Keyword: Industrial robot; Punch; Gold of Ban of automobile body of automation foreword car punch line is the important equipment in car production process, its produce quality and efficiency to affect the quality of the car and manufacturing efficiency directly. Punch production automation is to raise labor productivity and the significant step that improve labor condition and main method. Rise ceaselessly and expand of scale of production as quality of product of our country car, electric equipment ceaselessly, automation of production of implementation of industry of punch of our country metal is imperative. The in comparing punch technology producer type of all sorts of producer type has L traditional artificial production pattern (if pursue,show 1 times) produce kind with automation (if pursue 2 show 3 times with the graph) . Each respect has efficiency of intensity of work of the stability from product quality, staff, safe production, production quite, automation produces means to have larger dominant position, also be the development trend of punch production means. Automation product line divides punch to be mixed for product line of automation of manipulator automation product line, robot again multitask the means such as compressor product line. The distinction of manipulator automation product line and robot automation product line basically behaves in the following respects: (1) install means: Robot line is installed in the ground, do not have the join on machinery with compressor; Manipulator line installs girder between compressor pillar, adherent go up in compressor. (2) use characteristic: Robot line passes Duan Shi implement of switch and robot movement contrail adjust, more flexible change. (3) manufacturing metre: Metre of robot line production is 7 / Min~10 / Min, manipulator line is 8 / Min~12 / Min. (4) investment cost: Robot line investment is low, manipulator line investment is high. Because manufacturing metre is an integrated index, it depends on not only some equipment, and depend on automation equipment, compressor, mould 3 person harmonious match a relation, if achieve 10 / Min above, rise accordingly to the requirement of compressor and mould, mean investment to increase. Integrated consideration, use robot automation line more economy, applicable. Manipulator automation the line is comfortable the compressor product line at big span, apply to the automation that already had product line to transform at the same time. Through changing end is picked up implement, robot automation product line can suit the production of much model, flexible taller. Graph sketch map of product line of 3 robots automation. Product line of automation of 2 robots punch designs product line of robot automation punch to run circular means to be: The battlements expects tear open a battlements (the robot tears open a battlements) one board makings transmits one board material oiled one board stuff is right in go up makings robot sends expect one (first press punch) makings robot is taken makings, send expect one (press punch) (the basis is versed in. The article is a control of pair of its whole layout, electric equipment to wait with the product line of robot punch automation of Great Wall car undertake specific design. 2.

System of cost of 1 system group includes the system that tear open a battlements, oiled machine, stage in be opposite, compressor to hold fluctuation concurrently to expect tail of system, string carries a system. The system that tear open a battlements is used can circulate stage of makings of type double battlements, slideway decorates parallel at compressor, makings of strong pressing plate uses drive a vehicle or forklift is placed go up in stage of makings of blame job battlements, affirm through effective signal next on makings end, systematic general changes a battlements automatically after tearing open a battlements to finish makings stage, assure serial production; In the battlements magnetic force is deployed to divide Zhang Qi on skip, tear open a battlements automatically to become sheet through makings of battlements of magnetic force general piece. There is of reinforced material to detect on the robot that tear open a battlements and unit of processing of of reinforced material is sheet every time with assuring piece send makings. The robot that tear open a battlements lays board material go up in the magnetic conveyer belt with adjustable length, board makings sends to oiled machine, board makings is oiled buy of the oil level that reach besmear can adopt set of process designing proper motion, after board makings is oiled, the stage in conveying to be opposite. The stage in be opposite uses machinery to be opposite in stage, can undertake move and be fixedded conveniently, use gravity is right at the same time medium or the vision is right in system, the repetition that assures board makings locates quick, accurate with firm; Expect on robot basis the in be opposite position of every spare parts, the change runs orbit, carry board material well and truly compressor inside; Make an imitate that undertakes a robot show to different punch religion, from line process designing, in order to suit a variety of making in all line production; String tail is carried use leather belt machine, leather belt engine is placed in the extreme of product line, the robot that assures last compressor sets the part leather belt machine to go up directly, achieve give an effect. Make through software the robot dogs the motion of press, realize press and robot synchronism function, can the biggest change the registration between fluctuation makings and press campaign, achieve smooth switch its speed will shorten manufacturing metre and the goal that reduce mechanical negative charge. Through increasing exterior axis, undertake as the 7th axis of the robot servo is controlled, make the span between compressor is decorated more free; In the meantime, the deferent limits of the robot and carry speed to get promotion, manufacturing metre is faster. 2.
