Device for feeding after cutting pole pieces

Abstract

The invention discloses a device for feeding after cutting pole pieces. The device comprises at least two adsorption mechanisms, a rotating frame and a rotation driving mechanism. Each adsorption mechanism comprises a sucker and an adsorption driving piece. Each sucker is provided with a plane used for holding the pole pieces. Adsorption holes and cutting grooves are formed in the planes. The adsorption holes are communicated with the adsorption driving piece. The shape of each cutting groove is matched with the shape of a to-be-cut pole piece. At least two adsorption mechanisms are mounted on the rotating frame. The rotation driving mechanism is connected with at least two adsorption mechanisms through the rotating frame. The rotation driving mechanism can drive the at least two adsorption mechanisms to rotate alternately at a cutting position and a feeding position, so that direct feeding can be realized after cutting of the pole pieces, and production efficiency of the pole pieces is improved; cut pole pieces are rotated rapidly to the feeding position from the cutting position by the rotation driving mechanism, and the adsorption mechanisms are directly driven by an air cylinder to feed, so that steps of positioning, picking and transporting of a manipulator are omitted, position accuracy of lamination is guaranteed, and production efficiency of the pole pieces is further improved.

Description

technical field [0001] The invention relates to the field of lithium ion battery production and manufacturing, in particular to a device for feeding pole pieces after cutting. Background technique [0002] In the production process of lithium-ion batteries, battery pole piece cutting and feeding are necessary processes before battery pole piece lamination. The quality of cutting and feeding directly affects the success of battery pole piece lamination. In the current process, the cutting of the battery pole piece is to fix the pole piece on the cutting table and cut it by laser. After cutting, the cut pole piece is supplied to the stacking device by the robot for stacking. In the current process, after the pole piece has been cut, the cutting device must be withdrawn first, and then the material is fed by the manipulator. The cutting and feeding need to be separated and cannot be carried out at the same time, which cannot meet the needs of high-speed lamination; and each fee...

AI Technical Summary

Problems solved by technology

In the current process, after the pole piece has been cut, the cutting device must be withdrawn first, and then the material is fed by the manipulator. The cutting and feeding need to be separated and cannot be carried out at the same time, which cannot meet the needs of high-speed lamination; and each feeding time After the cutting device exits the cutting position, the manipulator can enter to pick up the pole piece. In order to pick up the accuracy, the pole piece must be positioned first. In the process of reciprocating positioning and picking, it is inevitable that the positioning is not accurate and the lamination is not accurate. There will be bruises and other phenomena when removing the pole piece after picking up, and it takes time to pick up each positioning, which further reduces the speed of cutting and feeding, so that the speed of the entire stack is reduced
