Abstract

The invention discloses a three-dimensional brittle object pickup device. The three-dimensional brittle object pickup device comprises a tube body, a piston, a suction cup, an adhesive film and a pushrod, wherein the piston is movably arranged in the tube body and divides the internal space of the tube body into an upper chamber and a lower chamber; the suction cup is connected with the lower endof the tube body; the adhesive film is suitable for adhering to a three-dimensional brittle object, the lower portion of the suction cup is covered with the adhesive film, and the adhesive film and the suction cup define an adjusting cavity; the adjusting cavity communicates with the lower chamber to enable the volume of the adjusting cavity to change along with volume change of the lower chamber; and the lower end of the push rod is connected with the piston, and the push rod extends out of the tube body from the upper end of the upper chamber. The three-dimensional brittle object pickup device provided by the embodiment of the invention has the advantages of being reliable in pickup, high in applicability, low in cost and the like.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a three-dimensional brittle object picking device. Background technique [0002] The grasping technology for picking up, transferring and releasing three-dimensional brittle objects such as balls and silicon wafers in millimeter and centimeter scales is an important link in practical applications such as laboratory assembly and precision manufacturing. [0003] The three-dimensional brittle object pick-up device in the related art is based on the vacuum adsorption method, but there are problems such as uneven stress, small adsorption force, difficulty in grasping the spherical surface, and limited size. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a three-dimensional brittle object picking device, which has the advantages of reliable picking, str...
