Non-contact robot gripper

Abstract

The invention provides a non-contact robot gripper and belongs to the technical field of mechanical grippers. The non-contact robot gripper comprises a robot, a frame and a plurality of non-contact suckers. According to the non-contact robot gripper, an arm of the robot is connected with the frame with the multiple non-contact suckers, and the bottom of a sucker body of each non-contact sucker isprovided with an annular groove and a third channel which is tangentially arranged along the side wall of the groove and communicates with the groove, so that gas can flow out from the third channel in the tangential direction of the side wall of the concave cavity and forms spiral motion under the constraint of the inner wall of the concave cavity, thereby generating vacuum suction force. A glasssubstrate is adsorbed, grabbed and transferred without contact, so that the problems of surface pollution, scratches, damage and deformation caused by contact are avoided, the quality of the glass substrate is guaranteed, the requirement of subsequent processing is met, and production and manufacturing of the glass substrate are facilitated.

Description

technical field [0001] The invention relates to the technical field of mechanical grippers, in particular to a non-contact robot gripper. Background technique [0002] Glass substrates are widely used in the flat panel display industry and are one of the core components to ensure the performance of flat panel displays. Their surface quality directly affects the quality of subsequent products. Therefore, improving the production quality of glass substrates has become the focus of industry research. [0003] At present, the transfer of glass substrates in different processes in the industry is mainly handled by mechanical grippers, and contact vacuum chucks are mainly used to achieve the adsorption, grasping and transfer of glass substrates. Vacuum chucks need to contact the surface of the glass substrate, which is easy to cause Glass substrates suffer from damage, scratches, and surface contamination. Moreover, with the continuous development of glass substrates towards thin...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned problems existing in the prior art, it is now intended to provide a non-contact robot gripper, to set several non-contact suction cups, and the above-mentioned several non-contact suction cups are installed on the robot arm through the frame, so that when facing the glass When the substrate is grasped, the non-contact suction cup can realize the adsorption, grasping and transfer of the glass substrate without touching the surface of the glass substrate, avoiding the problems of surface pollution, scratches, damage and deformation caused by contact with the glass substrate , better guarantee the quality of the glass substrate, better meet the needs of subsequent processing, better applicability, and more conducive to the production and manufacture of glass substrates
