a pick-up device

Abstract

The invention relates to a workpiece taking device. The workpiece taking device comprises a shell; a cavity is formed in the shell, the cavity is connected with a sucking pump, first grooves are formed in the outer surface, in contact with a workpiece, of the shell, a through hole is formed in the inner bottom face of each groove, a sealing part is arranged at each through hole, each sealing part comprises a connecting column, a first sealing plate and a second sealing plate, the first sealing plates are matched with the through holes and located in the through holes, the second sealing plates are located in the cavity, and the area of each second sealing plate is larger than each through hole, the second sealing plates are mutually attached to the first sealing plates, each second sealing plate comprises a left half portion and a right half portion which are symmetrical, the left half portions and the right half portions of the second sealing plates and the first sealing plates are all rotatably connected to the connecting columns, and the lower side face of each first sealing plate is connected with a first supporting rod. The workpiece taking device can suck and transfer the workpieces with different grooves or holes on the surface and accurately and automatically select a best sucking point, the application range is wide, production efficiency is improved, and the damage degree of the workpieces is reduced.

[0002] In the process of auto parts processing, it is necessary to use a reclaiming device to take out and transfer the finished workpiece. The traditional method is to take out and transfer the workpiece by clamping the workpiece, but in the process of clamping in this way, The fixture and the workpiece are easy to slip, scratch the workpiece or cause the workpiece to drop and damage

[0003] In order to avoid the above-mentioned damage, the method currently adopted is to suck the workpiece by air pumping, and then take it out and transfer it, which solves the above-mentioned problem well, but because many workpieces of auto parts have several concave holes of different sizes Grooves or holes, when the reclaimer sucks the workpiece, these grooves or holes will cause the workpiece to loosen from the reclaimer, because the reclaimer and the workpiece communicate with the outside air from the groove or hole, Causes the suction force of the reclaimer to the workpiece to become weak

[0004] For this kind of problem, at present, only by moving the suction position when picking up the workpiece to avoid grooves or holes, not only is it very troublesome, but the same pick-up device is often not suitable for different workpieces
