Automatic fetching device

Abstract

The invention relates to an automatic fetching device which comprises a shell. A cavity is formed in the shell and communicated with an air suction pump, a plurality of first grooves are formed in the outer surface of the shell, a first through hole and a second through hole which are communicated with the cavity are formed in the undersurface of each first groove, a sealing piece movably sealing the corresponding first through hole is arranged at the first through hole, a rubber film sealing the corresponding second through hole is formed at each second through hole, one side, facing the corresponding first groove, of each rubber film is fixedly connected with a supporting rod while the other side of the same is hinged to a first connecting rod which is supported through a supporting block, and each first connecting rod is hinged to a second connecting rod which is connected with the corresponding sealing piece. The automatic fetching device can suck and transfer workpieces with different grooves or holes in the surfaces and is good in suction effect and wide in application range, production efficiency is improved, and workpiece damage degree is reduced.

Description

technical field [0001] The invention relates to an automatic material retrieving device. Background technique [0002] In the process of auto parts processing, it is necessary to use a reclaiming device to take out and transfer the finished workpiece.

[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
