Battery cell pole piece shaping device

Abstract

The invention discloses a battery cell pole piece shaping device which comprises a shaping bottom plate. Supporting blocks are fixedly connected to the two ends of the shaping bottom plate, a flat plate is fixedly connected to the two supporting blocks, a sliding block is slidably connected to the flat plate, and a first driving mechanism for driving the sliding block to move is arranged on the flat plate. A deformed battery cell pole piece is placed on the top of a shaping bottom plate, a second driving mechanism is started, the conical surface of a conical block is driven to abut against the outer surface wall of an arc-shaped block, a rotating block is driven to rotate, a pressing block is driven to press the battery cell pole piece to fix the battery cell pole piece, and a piston rod of a second air cylinder is started to move to drive a sliding block to move till that the shaping block is located above the deformation position of the battery cell pole piece; and the piston rod of a first air cylinder is started to extend out, the shaping block is pressed at the deformation position of the battery cell pole piece, the battery cell pole piece is shaped, the operation is simple, the shaping working efficiency is improved, the shaping stability of the device is good, and the quality of the shaped battery cell pole piece is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of shaping devices, and in particular, to a shaping device for cell pole pieces. Background technique [0002] Lithium-ion batteries have the advantages of high energy density, high working voltage, light weight, small size, good safety and environmental protection. They have broad application scenarios in portable weapons, power tools and electric transportation power sources. It is the part that makes up the lithium ion battery, and the size of the electrode pieces in different lithium ion batteries is different. [0003] The existing battery pole pieces are stacked or contacted and squeezed during the production or assembly process, resulting in the deformation of the battery pole pieces. Reshaping, then the deformed electrode pieces can only be scrapped. [0004] Therefore, when the cell pole piece is deformed, it is necessary to reshape the cell pole piece to avoid waste. Most of the existing ...

AI Technical Summary

Problems solved by technology

[0003] The existing battery pole pieces are piled up or contacted and squeezed during the production or assembly process, resulting in deformation of the battery pole pieces. After deformation, the battery pole pieces will not be able to be installed inside the lithium-ion battery. Reshaping, then the deformed battery pole piece can only be scrapped

[0004] Therefore, when the pole piece of the battery cell is deformed, it is necessary to reshape the pole piece of the battery cell to avoid waste. Most of the existing shaping methods of the pole piece of the battery cell are manually shaped. However, first of all, it is cumbersome for workers to use rubber hammers to beat the operation, and the steps are cumbersome, which reduces the work efficiency of plastic surgery.
