Abstract

The invention discloses a three-dimensional brittle object picking device. The three-dimensional brittle object picking device comprises: a tube body; a piston, the piston is movably arranged in the tube body and divides the space in the tube body into an upper cavity a chamber and a lower chamber; a suction cup, the suction cup is connected to the lower end of the tube body; an adhesive film suitable for adhering to a three-dimensional brittle object, the adhesive film covers the bottom of the suction cup and jointly defines an adjustment chamber, the adjustment chamber communicates with the lower chamber so that the volume of the adjustment chamber changes with the volume of the lower chamber; push rod, the lower end of the push rod is connected with the piston and The upper end of the upper chamber protrudes from the tube body. The three-dimensional brittle object picking device according to the embodiment of the present invention has the advantages of reliable picking, strong applicability, and low cost.

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...
