A cell pole piece shaping device

Abstract

The invention discloses a battery pole piece shaping device, comprising a shaping bottom plate, support blocks are fixedly connected to both ends of the shaping bottom plate, flat plates are fixedly connected to the two support blocks, and sliding blocks are slidably connected to the flat plates , the flat plate is provided with a first driving mechanism for driving the sliding block to move. In the present invention, the deformed cell pole piece is placed on the top of the shaping bottom plate, and the second driving mechanism is started to drive the conical surface of the conical block to collide with the outer wall of the arc block, driving the rotating block to rotate, and driving the pressing block to press on the electric Fix it on the pole piece of the core, start the movement of the piston rod of the second cylinder to drive the movement of the sliding block until the shaping block is above the deformation of the pole piece of the battery, start the piston rod of the first cylinder to stretch out, and the shaping block presses on the pole piece of the battery to deform It is easy to operate and improve the work efficiency of shaping, and the shaping stability of the device is good to ensure the quality of the battery pole after shaping.

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 supplies. 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 existin...

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.
