Problems solved by technology

[0003] However, there is a big defect in increasing the adsorption force by adding a mechanical locking device
The mechanical locking device is locked after the vacuum extraction is completed, and cannot assist vacuum extraction; the mechanical locking force cannot be adjusted according to needs, the adaptability is poor, and the degree of automation is low; the mechanical locking device cannot change the environment where the vacuum suction cup is located Atmospheric pressure has no effect on the increase of the actual vacuum degree

Abstract

The invention discloses a vacuum sucker with functions of vacuumizing assisting and pressurizing. The vacuum sucker comprises a sucker body, a sucker seat connected with the sucker body and a pressurizing cavity, wherein compressed air can be injected into the pressurizing cavity. The vacuum sucker has the advantages that the vacuum sucker can assist the discharge of air in the sucker body during vacuumizing and pressurize an absorption surface during absorption so as to guarantee the reliability of sucker absorption, PLC control is used, high automation level is achieved, and manual operation is not needed.

Description

technical field [0001] The invention relates to a vacuum suction cup, in particular to a simple and practical vacuum suction cup with the functions of auxiliary vacuuming and pressurization. Background technique [0002] In the prior art, the suction force F of the suction cup depends on the suction area S of the suction cup, the degree of vacuum P and the safety factor μ, F=S*P / μ. When the adsorption area S is constant, the improvement of the adsorption force F mainly depends on the improvement of the vacuum degree P and the reduction of the safety factor μ. The equipment cost required to increase the vacuum degree P is relatively high, and the applied industries are relatively limited. At present, it is more common to increase the mechanical locking device to reduce the vacuum leakage rate and reduce the safety factor μ, thereby increasing the adsorption force F. [0003] However, increasing the adsorption force by adding a mechanical locking device has relatively large ...
