【正文】 re, welding the application of robot is to used for to give or get an electric shock the process of Hu Han in the beginning.Actually, industrial robot at welded the application of realm to produce online electric resistance to order a Han beginning from the car assemble at the earliest reason lies in the process that the electric resistance orders Han opposite more simple, control convenient, and not need Han to sew a track follow, to the accuracy of the robot and repeat the control of accuracy have lower the Han robot assembles to produce a great deal of online application to consumedly raise the rate of production that the car assemble welds and weld quality in the car, at the same time again have a gentle characteristics for welding, then want ～only change procedure, can produce in the same online carry on assemble to weld to different cars type.BE born till the beginning of this 8039。It is still a kind of labor condition bad, many smoke and dust, hot the radiation is big, risk Gao of emergence of the industrial robot makes people naturally thought of first the handicraft that replace a person with it welds and eases the welder39。Weld robot application present conditionAccording to inpletely statistics, the whole world about has in the industrial robot of service nearly half of industrial robots is used for multiform weld to process realm, weld robot of application in mainly have two kinds of methods most widespreadly, then order Han and electricity Hu we say39。s welding robot is in fact welding to produce realm to replace a welder to be engaged in the industrial robot of welding the weld to have plenty of to design for being a certain to weld a way exclusively in the robot of, but majority ofly weld robot in fact is an in general use industrial robot to pack up a certain weld tool but many task environments, a set robot even can plete include weld at inside of grasp a thing, porterage, install, weld, unload to anticipate etc. various tasks, robot can request according to the procedure with task property and automatically replace the tool on the robot wrist, the pletion corresponds of , e up to say from a certain meaning, the development history of industrial robot is the development history that welds robot.Know to all, weld to process to request that welder have to have welltrained operation technical ability, abundant fulfillment experience, stability of weld level。s labor strength, can also promise to weld quality and exaltation to weld an efficiency at the same time.However, weld again with other industry process process different, for example, electricity Hu Han process in, drive welder piece because of part heat melt with cool off creation transform, the Han sews of the track will therefore take place to Han the experienced welder can sew position according to the actual Han observed by eyes adjustment Han in good time the position, carriage of the gun and run about of speed to adapt to the variety that the Han sews a the robot want to adapt to this kind of variety, have to the position and status of gun that want tosee this kind of to change, then adopt homologous measure to adjust Han like person first, follow while carrying out to sew actually to the the electricity Hu welds to have in process strong arc light, give or get an electric shock Hu noise, smoke and dust and Rong drop transition unsteady and causable Han silk short circuit, big electric current strong magnetic field etc. plicated environment factor of existence, the robot wants to examine and identifies a withdrawing of the signal characteristic needed for sewing Han and don39。s in century from the robot, the robot technique experienced a development process of long term 39。s labor force cost contains the trend to continuously Nations European Economic Committee(UNECE) statisticses from the variety curve of 19902000 years of the robot price index number and labor force cost index them the robot price of 1990 index number and labor force cost the index number is all reference to be worth 100, go to 2000, labor force cost index number is 140, increased 40%。And consider that the quality factor means because the robot make the exaltation of craft technique level, manufacturing quality and function of robot even if want also under the condition of equal price pare high before, therefore, if pressed the past robot equaled quality and function to consider, the price index number of robot should be much lower.Can see from here, national in the west, because the exaltation of labor force cost brings not small pressure for business enterprise, but the lowering of robot price index number coincidentally expands application to bring a chance further for it the equipments investment of employee and increment robot, when their expenses attains some one balance point, the benefit of adoption robot obviously wants to pare to adopt the benefit that the artificial brings big, it on the other hand can consumedly raise the automation level of producing the equipments and raise to labor rate of production thus, at the same time again can prom
