Background technology
Along with the development of auto industry, the auto-producing automaticity is more and more higher, mode totally-enclosed, full robot manipulating task that automobile body-in-white welding generally the adopts operation that is welded.In order to guarantee whole line beat, by with other welding robots, roller bed, fixedly the equipment such as welding gun, fixture carries out joint control, automaticity and production efficiency have further been promoted, realized the manless production of whole line, except the robot that is welded, on the floor, the station such as total spellings also need arrange some transfer robots, realize the assemblies such as top cover, floor, left and right gusset are carried out robot crawl and accurately location placement.
The utility model content
Problem to be solved in the utility model is, for reaching transfer robot, the assemblies such as top cover, floor, left and right gusset are implemented crawl and accurately location placement, a kind of white car body top cover gripping apparatus is provided, realization is to the crawl of the assemblies such as top cover, floor, left and right gusset and accurately location placement, automaticity and production efficiency have namely been promoted, realize the manless production requirement of whole line, can satisfy again the flexible welding requirement of two kinds of top covers of a kind of vehicle.
The purpose of this utility model is achieved through the following technical solutions.A kind of white car body top cover robot gripping apparatus; the framework that comprises the matrix pattern that is formed by six roots of sensation straight-bar; be provided with from moving the gunlock structure at the upside of framework, the downside of side straight-bar is respectively equipped with some suckers before and after framework, is provided with Workpiece clamping protective device and sensor at the downside of frame left straight-bar.Adopt this scheme; robot arm inserts from moving the gunlock structure, picks up the top cover gripping apparatus, and robot can distinguish whether top cover puts in place by sensor; and then starting sucker absorption top cover, the Workpiece clamping protective device causes workpiece to drop to prevent the gas path failure sucker to lose efficacy.Robot is delivered to body in white top with top cover, and clamping protection device opens simultaneously, and sucker discharges and top cover is fallen into fixture accurately locates overlap joint, and clamps; After the top cover dropping place was complete, robot picked up the top cover gripping apparatus, was placed on the gripping apparatus frame, and robot separates with gripping apparatus, and the crawl welding gun carries out spot welding to top cover on gun rack; Weld complete rear robot welding gun is placed on gun rack, again pick up the top cover gripping apparatus to the gripping apparatus frame, and then go to grasp top cover assembly on the top cover bin; So far on complete top cover, part and welding process finish, and according to different vehicle testing results, the top cover that the robot crawl is different has improved flexibility and the automaticity of welding line greatly, has accurately controlled beat.
As preferably, described sucker is vacuum cup.Draw top cover with vacuum cup flexible.
As preferably, described sensor is metal sensor.Adopt this scheme sensor can distinguish enough exactly whether top cover puts in place.
The beneficial effects of the utility model are, can realize the crawl of the assemblies such as top cover, floor, left and right gusset and accurately location placement, namely promote automaticity and production efficiency, realized the manless production requirement of whole line, can satisfy again the flexible welding requirement of two kinds of top covers of a kind of vehicle.
The specific embodiment
The below is described in further detail the utility model in conjunction with the accompanying drawings and embodiments:
As shown in Fig. 1; a kind of white car body top cover robot gripping apparatus; the framework 1 that comprises the matrix pattern that is formed by six roots of sensation straight-bar; upside at framework is provided with from moving gunlock structure 2; the downside of the straight-bar of side side is respectively equipped with four vacuum cups 3 before and after the framework, is provided with Workpiece clamping protective device 5 and metal sensor 4 at the downside of framework opposite side straight-bar.
The above is the better specific embodiment of the utility model, is not to limit practical range of the present utility model with this.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
