Efficient pole piece cutting device for battery production

Abstract

The invention discloses an efficient pole piece cutting device for battery production and relates to the technical field of battery manufacturing. The efficient pole piece cutting device comprises an outer shell, wherein a baseplate is fixedly connected with the inner wall of the left side of the outer shell; a mounting block is fixedly connected with the outer wall of the baseplate; a second mold is fixedly mounted on the outer wall of the mounting block; a first mold is arranged corresponding to the right side of the second mold; a dust removal device is arranged at the bottom of the first mold, and comprises a square frame, rotating shafts, first square blocks, second square blocks, rotating rollers and bristles; the square frame is fixedly mounted in the middle of the inner wall of the outer shell through connecting rods; adjusting grooves are formed in both the front side wall and the rear side wall of the square frame; the first square blocks are fixedly mounted at the left ends of the adjusting grooves; second square blocks are slidably connected into the adjusting grooves; first springs are fixedly connected between the first square blocks and the second square blocks; the rotating rollers are fixedly mounted on the outer sides of the rotating shafts; and the bristles are fixedly mounted on the outer sides of the rotating rollers. Consequently, pole pieces can be effectively separated from powder impurities, and the classified collection can be facilitated.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a pole piece cutting device for high-efficiency battery production. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable battery. Lithium-ion batteries are different from lithium-ion polymer batteries. The inventor of lithium batteries is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment is increasingly Lithium batteries have entered a large-scale practical stage. Lithium-ion batteries generally use lithium alloy metal...

AI Technical Summary

Problems solved by technology

[0003] In the process of battery production, it is necessary to slice the battery pole pieces. The cutting machine is a device for cutting multiple pieces of lithium battery positive pole pieces. This equipment uses a cylinder to control two cutters to cut the pole pieces. The cutting length is positioned by the positioning block, and the operator manually places a single piece for single-piece cutting. The disadvantages are:

[0004] 1. After the cutting is completed, the pole piece will be contaminated with more cutting dust. The existing cutting device does not have a corresponding dust removal device, and the pole piece is directly dropped into the collection device after cutting, which is easy to cause damage due to impact

[0005] 2. During the operation, due to the small pole piece, the hand is close to the cutting edge, and there is a safety risk of cutting hands; the operator cannot fully guarantee the identity of each pole piece size during the process of placing the pole piece. It is easy to cause the pole pieces to be skewed and of different lengths;

[0006] 3. When the slitting equipment is slitting the pole pieces, it is easy to generate dust and the slit pole pieces are mixed together, and it is not easy to separate them
