Description

But quick replacement's sucking disc mechanism

Technical Field

The present invention relates to an end effector suction cup mechanism, and more particularly, to a quick replaceable suction cup mechanism.

Background

The end effector for grabbing the plate is an indispensable part of a punching automation production line head, wherein the vacuum sucker type end effector of the vacuum sucker type end effector is used for picking up a workpiece by utilizing negative pressure generated by a sucker at the tail end of the working process, the working principle of the end effector is that the vacuum sucker generating the negative pressure and equipment for manufacturing a vacuum state are connected together through an air pipe, the surface of the sucker is in close contact with the surface of the sucked workpiece, air is sucked by the equipment, so that the inside of the vacuum sucker is changed into the vacuum state, suction force is generated, the workpiece is picked up, after the workpiece is moved to a position needing to be reached, the equipment is used again to fill air into the vacuum sucker, so that the atmospheric pressure in the sucker is changed into normal atmospheric pressure from the vacuum state, the suction force is finally changed into zero, and the workpiece is separated from the sucker. The vacuum chuck type end effector can absorb workpieces produced by non-magnetic materials such as copper, aluminum, plastic and the like, and the surfaces of the workpieces cannot be scratched.

The sucking disc is an important component of the end effector, but the sucking disc is easy to wear and tear due to the fact that the sucking disc is made of rubber, the workpiece cannot be grabbed in the production process, the problem that the workpiece falls to cause alarm of a press machine and the like can occur, and therefore the sucking disc needs to be replaced frequently; meanwhile, because the sucker can not be fixed, a connecting component is required to be arranged to be connected with the end effector support arm, most of the prior art adopt a connecting mode that the rod chuck and the sucker component are fixed through bolts, the connection mode determines that 2-bar 12-inch shifting wrench tools are needed when the sucker component is replaced, the bolts for fixing the sucker are loosened by clamping the nuts, the auxiliary rod chuck is easy to generate small displacement and rotation in the disassembly process, the position of the sucker deviates after the auxiliary rod chuck is connected and assembled with the sucker in the assembly process, and the sucker cannot be accurately positioned, if the position does not need to loosen the bolt again and finely adjust, the adjustment is needed for many times, the stop time is increased by the mode of replacing the sucker, the production is delayed, the workpiece cannot be grabbed due to the position deviation of the sucker, the workpiece is dropped, the deformation and other problems cause the production of waste workpieces, and the replacement and adjustment of the sucker at each time averagely needs about 8 minutes.
