Description
Technical Field
The invention relates to a sucking disc for sucking and picking a flat workpiece.
Background
In many production lines of flat plate-shaped products, there are many processes for sucking and picking up flat plate-shaped workpieces, especially circuit board production enterprises. The production process comprises the following steps: the sucker group is pressed down to the upper surface of the flat-plate-shaped workpiece, and is pressed tightly and sucked, and the sucker group is pulled upwards. In this case, if the plate-shaped workpiece is perforated and it is entirely possible that one or more holes are located at the lower opening of one or more suction cups, then it is necessary to cause the suction cup or cups to leak air or to suck air. As a result, either the air pump is overloaded or the suction force is insufficient due to a decrease in the effective suction pad number and the workpiece falls off. Therefore, the development of a sucker group capable of avoiding air leakage is urgently needed, air leakage or less air leakage of the sucker group is guaranteed in the processes of pressing a flat plate-shaped workpiece with holes tightly, sucking air and pulling upwards, so that the flat plate-shaped workpiece with the holes is prevented from falling off, energy is saved, and the smoothness of the whole production automation process is guaranteed.
