Our country develops industrial robot to be later than the United States and Japan, result 20 centuries 70 time, inchoate the research of the spontaneity that is university and place of scientific research courtyard. To 80 time metaphase, the whole nation comes out without an industry robot. And be in abroad, industrial robot has been a very mature industry product, wide application received in automobile industry. In view of the domestic and international situation at that time, country " 75 " tackle key problem the plan included a plan the development of industrial robot, undertook tackling key problem to industrial robot, regard the serious content of assessment as application especially, link robot technology and user cheek by jowl so rise, make Chinese robot is in start level was aimed at practical the way that change. Include a country at will developing a robot 1986 meanwhile " 863 " high-tech plan. In the country " 863 " during planning to carry out 5 years, comrade Deng Xiaoping put forward " development high-tech, realize industrialization " target. Drive in what home market develops below, and on the foundation that the technology that researchs to robot technology lays in, group of 863 themes expert undertook in time adjustment mixing to main attack direction outspread, regard research as to develop one of stresses industrial robot and applied project, put forward to drive the development policy of crucial technology and basic research in order to apply, include a country again later " 85 " and " 95 " in. Try hard through abidance of ten years, below national organization and support, our country solders the research of the robot is in fundamental technology, control technology, crucial the respect such as yuan of parts of an apparatus obtained significant progress, already entered use change level, formed spot welding, arc welding machine implement person series product, can realize small lot production. Our country solders the applied state our country of the robot solders the application of the robot basically is centered in engine of machine of car, autocycle, project, railroad to wait for a few main industries. The car is to solder the biggest user of the robot, also be the earliest user. Be in early 70 time end, shanghai electric welder factory moves tool institute with Shanghai report, the rectangular coordinates manipulator that collaboration develops, apply successfully at batholith of Shanghai card car solder. "One steam " it is our country is introduced the earliest solder the enterprise of the robot, from KUKA the company introduced robot of 3 spot welding after 1984 at first, use at that time " red flag card " the automobile body of the car solders and " emancipatory card " of automobile body coping solder. Will solder successfully 1986 the robot applies at front wall assembly solder, developed line of total solder of robot automobile body 1988. 80 time end and at the beginning of 90 time, german people corporation establishs joint-stock car plant to produce a car with one steam with Shanghai respectively, although be abroad secondhand equipment, but its solder automation degree and equipment standard, let us realise the huge gap with abroad. Subsequently 2 steam were introduced in van and light-duty car project solder robot. The transfer of technology since can saying 90 time is introduced with what produce equipment, tooling make the car of our country makes a level raise dimensions to turn production by original mill type production, make abroad solders at the same time the robot enters China in great quantities. The high speed development that builds as a result of our country infrastructure drove the prosperity of project machinery industry, mechanical industry also becomes the project to cite earlier solder one of industries of the robot. Develop as a result of the high speed of our country economy in recent years, a large number of demand of the sources of energy, the production industry related to the sources of energy also begins to seek automation to solder technology, solder the robot cuts a figure gradually. Because railroad engine industry increases of the demand such as subway of our country freight, passenger transport, city ceaselessly, and train is carried fast demand, the demand of the robot is in all the time rise situation steadily. According to 2001 statistic, the whole nation is mutual and of all kinds solder robot 1040, the car is made and company of car component production solders mediumly the robot is occupied solder entirely 76% of the robot. Solder robot and arc welding machine order in automobile industry implement the person's scale is 3: 2, other industry is mostly with arc welding machine implement the person is given priority to, basically distributing in project machine (10% ) , autocycle (6% ) , railroad traffic (4% ) , boiler (1% ) wait for an industry. Solder the robot basically also distributings in the whole nation a few old automobile factories, from the graph 1 in still can see, our country solders the industry of the robot distributings disequilibrium, not quite extensive also. As a result of,enter 21 centuries of foreign car tycoon swarm into ceaselessly, automobile industry is swift and violent develop, the robot of industry of our country automobile installs a several mushroom, 2002, 2003, the amount that has nearly 1000 every year 2004 grows. Estimation our country solders at present the installation stage number of the robot is controlled in 4000. Automobile industry solders the proportion that robot place holds can rise further. The robot that uses in our country at present basically divides day of department, Europe is to mix homebred 3 kinds. There basically is An Chuan, OTC, pine to fall in day department, FANUC, not 2 more, the product of the company such as plain Qi. The IGM company of the COMAU of the ABB of the KUKA that there basically is Germany in Europe department, CLOOS, Sweden, Italy and Austria. Homebred robot basically is product of company of robot of Shenyang new pine. Although had had own intellectual property,be in our country at present solder robot series product, but however cannot batch production, form dimensions, have the following main reasons: Domestic robot price does not have an advantage. Come nearly 10 years, the price that imports a robot is reduced substantially, from every 7-8 10 thousand dollars reduce 2-3 10 thousand dollars, the common industry robot that makes our country proper motion is made competes very hard on the price to it. Especially the initial stage that our country is developing a robot, develop corresponding component property without synchronism, if the need such as machine of servo electric machinery, decelerate is imported, make the price is reduced hard, so the robot produces cost not to fall; Our country solders equipment standard and abroad still are put in very big difference, this also affected the development of domestic robot secondhand. The biggest user to the robot, - for manufacturer of car white automobile body, at present almost all equipments are introduced from abroad, homebred robot looks for the arena that is less than a performance almost. No matter wait for respect and foreign company to still exist from control level or dependability,we should admit homebred robot certain difference. Foreign industry robot is a very mature industry product, experienced 30 old development course, and be perfected ceaselessly in actual production and rise, and our country is in a kind of sheet the manufacturing condition of small lot. Domestic robot produces manufacturer to be in infancy, still need the support of governmental policy and capital. Solder the hi-tech product that the robot is an Electromechanical unifinication, the oneself ability that sheet relies on an enterprise is insufficient, need government produces enterprise and the company that use homebred robot system to give proper policy and capital support to the robot, accelerate the development of our country homebred robot. Application solders the meaning of the robot solders the 40% above that the robot can hold gross of whole industry robot, with solder this special industry is concerned, solder as industry " sartorial " , it is the very important process instrumentation in industrial production, the existence that because solder,at the same time soot, arc, metal splatters, soldering working environment very abominable, solder the stand or fall of quality has conclusive effect to product quality. Baconian rise use solder the robot has following and main sense: (1) stabilize and rise solder quality, assure its homogeneity. Solder if parameter solders electric current, voltage, solder speed and solder dry extend length to wait to have decision effect as a result to soldering. When using a robot to solder to every welding line solder parameter is constant, the element effect that welding line quality gets a person is lesser, reduced the demand that handles a technology to the worker, because this solders,quality is stable. And when soldering artificially, solder speed, dry stretchy etc is change, because this accomplishs the homogeneity of quality very hard. (2) the labor condition that improved a worker. Use the person just uses robot welder to assemble and unassemble workpiece, was far from solder arc, aerosol and splatter etc, to spot welding the worker carries cumbersome manual solder clamp no longer, make the worker comes out from the disengagement in the physical labor of great strength. (3) improve labor productivity. The robot does not have exhaustion, one day but 24 hours of serial production, additional as high speed efficient solder technical application, use robot solders, what efficiency rises is more apparent. (4) product cycle is specific, control product output easily. The manufacturing metre of the robot is fixed, because this plans production,plan very clear. (5) can shorten the cycle of product remodel replacement, reduce corresponding installation cost. Can realize small lot product solder automation. The biggest distinction of robot and private plane is he can pass modification program to differ in order to suit the production of workpiece. Our country solders robot application project solders robot application technology is robot technology, solder the confluence of technology and systematic project technology, solder robot whether get applied in actual production, develop its advantageous character, depend on people is right the shirt-sleeve degree of afore-mentioned technologies. Through effort of nearly 10 years, our country installs clamping apparatus to designed a respect to accumulate richer experience in robot solder, robot peripheral realized standardization, have produce per year more than 300 to solder the ability of robot workstation. The design that compositive business makes station and simple solder hold a line artificially in the machine develops the system that can say country the capacity that the respect had as compositive as foreign system business to contend, offerred many robot to solder for the enterprise such as domestic car component in last few years system. But the fact with serious another is, we still do not have the solder of robot whole set of production Gao Shuiping to act the capacity of the line. By foreign robot system compositive business design makes the line of outfit of automobile body solder of a few old car plants of domestic. As solder the biggest user of the robot, the car of 10 years of our country of predicting future produces per year a quantity to want to achieve ten million, present solder equipment cannot satisfy manufacturing requirement far, the demand that equips to soldering will increase considerably, solder outfit product line asks more automation and flexible change, in order to get used to the manufacturing demand of much breed, small lot, the robot receives a large number of application product line at solder in. How opportunity is being seized for compositive to the robot system of our country business is the main task that should solve currently, from tell on the other hand also decide the move is homebred solder the destiny of the robot. (1) executes cartel. Compositive business and car manufacturer combine robot system, digest absorb foreign car solder to hold a line. (2) builds him solder equipment design standard and digital-to-analogue, improve design level and efficiency. (3) strengthens a talent to foster construction. Robot solder deliver a child produces a line is a complex systematic project, involve mechanical, electric, content shedding to transmit, design of the computer, car is made, robot technology, solder a variety of course such as the technology, and our country still is done not have at present about this respect relatively of the system groom orgnaization. (4) strengthens the cooperation with foreign company, raise oneself design level through cooperative study. Solder the newest application technology of the robot (1)TCP (center of tool of Tool Center Point) automatic school 0 technologies solder the end points of the welding wire that the tool center of the robot is welding torch, because the null precision of this TCP is being affected directly,solder the stability of quality. But inevitable in actual production meeting produces the collision between welding torch and clamping apparatus to wait cannot foresight element brings about TCP position deviate. Normally the practice is to use a hand to move have robot TCP school 0, but general whole process needs ability 30 minutes to finish, the influence manufactures efficiency. TCP automatic school 0 it is one of be used in the robot to solder new technology, its hardware establishment is by one echelon fixed pedestal and sensor of a group of laser are comprised. When welding torch passes TCP pedestal with different attitude, the data that laser sensor plays the record delivers CPU and first set value to undertake comparative with computation. When TCP happening deviate, the robot can move automatically school 0 programs, undertake automatically adjustment to the angle of every axis, restore TCP null inside least time. (2) double silk solders the high speed that waits for an industry as a result of machine of car of our country car, container, engine, project in recent years develops the technology, the demand that solders to high speed solder and efficiency of tall frit apply is increasing. Double silk solder is a kind of high speed that in recent years development rises efficient solder method, solder can rise significantly when thin plate solder speed, achieve 3 ～ 6m/min, solder thick board when can improve frit apply efficiency. Besides high speed efficient outside, double silk solders to still have the craft characteristic of other: Inferior hot input maintains when frit apply efficiency increases, hot influence area is small, solder be out of shape small, rate of solder coherent aperture is low. Because solder rate is very high, suit to use a robot to solder particularly, because this can say the application of the robot,also drove this one advanced solder technical development. At present double silk solder basically has 2 kinds of kind: 1 kind is Twin Arc law, additional 1 kind is Tandem law. Solder the basic composition of equipment is similar, it is solder by 2 2 power source, machine sending silk and a common cable that send double silk. To prevent to be the same as the mutual interference of 2 phasic electric arc, often use method of solder of MAG of pulse MIG/ pulse, maintain 2 electric arc to burn alternately by turns. Come so, be about to seek a cooperative control implement the weaveform of output electric current that assures 2 power supply is phasic differ 180 ° . Should solder parameter is installed optimal when, pulse electric arc can get do not have short circuit, transfer without what splatter almost process, accomplish truly " a pulse transfers a frit drips " , the size that every frit drips is almost identical, its size is by electric arc power is decided. The main production manufacturer of Twin Arc law has German SKS, Benzel and Nimark company, miller company of the United States. Fronius of the wants manufacturer to have Germany Cloos of Tandem law, Austria and American Lincoln company. Introduce according to German Cloos company, use Tandem law to solder when thin plate of 2 ～ 3mm, solder speed can amount to 6m/min, solder 8mm above is thick board when, frit apply efficiency can amount to 24Kg/h. (3) laser / electric arc is compound solder technical laser / electric arc is compound solder the technology is the combination that laser solders to protect solder with gas, two kinds solder heat source at the same time action solders at bath. The research of this technology gives the century on now the earliest 70 time end, but the high price as a result of laser, restricted its to apply mediumly in industry. As laser and performance of arc welding equipment rise, and of laser price reduce ceaselessly, the pressing demand that produces to satisfy at the same time, laser / electric arc is compound solder the technology is become in recent years solder one of research tasks with the mainest field. Laser / electric arc is compound solder the combination that the technology has a variety of forms, have laser / TIG, laser / MAG and laser / MAG. Laser / electric arc is compound solder what because its hold each heat source concurrently,the technology is by favour is long and fill respective short, have 1+1>2 or more " synergism " . Solder to be compared with laser, to assembling the requirement of clearance to reduce, reduced cost of preparation of the workpiece before solder consequently; The inherent blemish that because fill welding wire was eliminated,exists additionally, welding line is more compact. Compare the stability that increased electric arc and power density with arc welding photograph, rose to solder speed and welding line frit are deep, heat affects area decrescent, those who dropped work be out of shape, eliminated the fused and undesirable flaw when removing arc. Solder in what go up at this o'clock to suit aluminium and its alloy particularly. Laser / electric arc is compound solder the technology is the significant progress that receives to laser beam welding, solder to be able to reduce laser power half to control with the material with large model, because this reduced the investment cost of the enterprise greatly, the development of this technology popularizes the effect with will rise main to driving what laser beam welding receives. (4) the applied servo robot in the craft of car outfit solder of technology of servo solder vice solder clamp, use servo electric machinery to replace namely compress air clamp of a kind of as dynamical source new-style solder. It has the following advantage: What because use,① raises the clamp of solder of exterior quality servo of automobile body is servo electric machinery, the behavioral speed of electrode is before workpiece of bring into contact with, can adjust low speed well and truly by high speed, such, can form the electrode soft contact to workpiece, reduce electrode to pound the impress that causes, surface of automobile body of the foreword after also was being reduced thereby is repaired grind treating capacity, improved automobile body quality. And, technology of applied servo control is OK to soldering parameter undertakes digitlizing control management, can assure to offer piece the most comfortable solder parameter data, assure to solder quality. Because electrode is right,② improves work environment of workpiece is soft contact, can reduce concussion noise, also won't appear the exhaust noise that causes when clamp of use pneumatic solder. Improved the work environment of the spot. The pressurization that ③ Gao Sheng produces clamp of efficiency servo solder opens a movement to come by the robot automata. Compare with photograph of pneumatic solder clamp, the behavioral path of servo solder clamp can be controlled the shortest change, shorten manufacturing metre, improve manufacturing efficiency. Current, will consider from the angle of investment, investment that buys equipment of servo solder clamp is higher, accordingly, servo solder clamp still cannot be used extensively. But, considering the advantage of servo solder clamp, for example the soft contact of servo solder clamp is changed, the concussion to workpiece can be reduced, can reduce the amount of fixture clamp orgnaization relatively thereby, the cost that cuts clamping apparatus, also can reduce the integral investment of product line, servo solder clamp still has its vast application space. Accordingly, as development, servo solder clamp meets increasing on product line applying. The research of industrial robot technology, development and application, effectively drove the progress of world technology. Solder especially the robot receives production in the solder of Gao Zhigao effect in, produced all in all effect. Competition of the international after joining WTO as our country is more intense, can bigger and bigger to the demand of industrial robot, the industrial robot industry of our country will face new development opportunity and the challenge that come from abroad, we should grasp this one opportunity, meet a challenge, for body of our country ascend at robot powerful nation and make arduous efforts.
