1、Weld robot application present conditionAccording to incompletely 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, th
2、en order Han and electricity Hu Han.What we says welding robot is in fact welding to produce realm to replace a welder to be engaged in the industrial robot of welding the task.These weld to have plenty of to design for being a certain to weld a way exclusively in the robot of, but majority ofly wel
3、d robot in fact is an in general use industrial robot to pack up a certain weld tool but constitute.In many task environments, a set robot even can complete include weld at inside of grasp a thing, porterage, install, weld, unload to anticipate etc. various tasks, robot can request according to the
4、procedure with task property and automatically replace the tool on the robot wrist, the completion corresponds of task.Therefore, come 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 tha
5、t welder have to have well-trained operation technical ability, abundant fulfillment experience, stability of weld level;It is still a kind of labor condition bad, many smoke and dust, hot the radiation is big, risk Gao of work.The emergence of the industrial robot makes people naturally thought of
6、first the handicraft that replace a person with it welds and eases the welders 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 w
7、elder piece because of part heat melt with cool off creation transform, the Han sews of the track will therefore take place to change.Handicraft 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
8、run about of speed to adapt to the variety that the Han sews a track.However 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
9、 actually to the Han.Because 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. complicated environment factor of e
10、xistence, the robot wants to examine and identifies a withdrawing of the signal characteristic needed for sewing Han and dont seem to be industrial the other in the manufacturing to process the examination of process so easily, therefore, welding the application of robot is to used for to give or ge
11、t an electric shock the process of Hu Han in the beginning.Actually, industrial robot at welded the application of realm to produce on-line electric resistance to order a Han beginning from the car assemble at the earliest stage.The reason lies in the process that the electric resistance orders Han
12、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 request.Order the Han robot assembles to produce a great deal of on-line application to consumedly raise the rate of production that the car as
13、semble 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 on-line carry on assemble to weld to different cars type.BE born till the beginning of this 80s in century from the robot, the robot te
14、chnique experienced a development process of long term slowness.90s, along with the rapid development of calculator technique, micro-electronics technique, and network technique.etc., the robot technique is also flown soon a development.The manufacturing level, control speed and control accuracy and
15、 dependable sex etc. of industrial robot continuously raises, but manufacturing cost and price of robot continuously descend.Is social in the west, with contrary robot price BE, the persons labor force cost contains the trend to continuously increase.United Nations European Economic Committee(UNECE)
16、 statisticses from the variety curve of 1990-2000 years of the robot price index number and labor force cost index number.Among 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%;But robot under the sistuation that consider a quality factor the price index number is lower than 20, lowered 80%, under the sistuation that take no account of a quality
