Suction disc device with ejection structure

Abstract

The invention provides a suction disc device with an ejection structure. The suction disc device comprises a base, a suction disc mechanism, an ejection mechanism, a hoisting mechanism and a limiting mechanism, wherein the ejection mechanism is fixedly connected to the suction disc mechanism; the hoisting mechanism drives the suction disc mechanism to do vertical movement; the limiting mechanism has a limiting effect on a route of the hoisting mechanism; the suction disc mechanism comprises a suction disc and a quick plug connector; a first through hole is formed in the end of the suction disc; the first through hole is communicated with the quick plug connector; a second through hole is further formed in the suction disc; the ejection mechanism comprises a push rod, an air cylinder seat and an ejection air cylinder; the ejection air cylinder and the suction disc are fixed on the air cylinder seat; the push rod is fixedly connected to a piston rod of the ejection air cylinder; and the push rod is located in the second through hole. When the suction disc device with the ejection structure, provided by the invention, is used for sucking, thin-sheet type objects are not bent and deformed; and influences of static electricity, friction and the like can also be overcome when the objects are put down and the objects can easily fall into an effective appointed region.

Description

technical field [0001] The invention belongs to the field of picking and placing objects, in particular to a suction cup device with an ejection structure. Background technique [0002] In automatic production, the grabbing and transporting of objects is an important link. In the existing technology, the structure of picking and placing small and thin sheet objects generally adopts a structure with a suction cup at the end, and the suction cup is made of rubber or silica gel. However, this kind of suction cup has the following disadvantages: when picking up items, because the end is a vacuum suction cup, the suction force is relatively large, and grabbing thinner or less hard items, such as films, will deform the item, causing creases or even damage ,Affect. When dropping items, due to reasons such as static electricity, the items cannot fall from the suction cup in time, which affects production efficiency. Especially in the occasions where the quality requirements for th...

However, this kind of suction cup has the following disadvantages: when picking up items, because the end is a vacuum suction cup, the suction force is relatively large, and grabbing thinner or less hard items, such as films, will deform the item, causing creases or even damage ,Affect

When dropping items, due to static electricity and other reasons, the items cannot fall from the suction cup in time, which affects production efficiency

Especially in occasions where the quality of the items to be picked and placed is high, the general picking and placing mechanism can no longer meet the requirements
