Slicing machine for producing slice laminated pole piece

Abstract

The invention discloses a slicing machine for producing a slice laminated pole piece. According to the slicing machine for producing the slice laminated pole piece, the synchronization technology is adopted for a punching assembly and a cutter assembly, both punching and cutting are achieved through the slicing machine when a blank is operates, both the efficiency and the precision of the machine are improved, the efficiency of the slicing machine is about three times that of the prior art, the mechanical structure of the slicing machine is greatly simplified, operation is convenient, and the failure rate is low; due to the fact that a hardware mold is used for punching, burrs and dust generated during pole piece forming are effectively reduced, the pole piece is driven to move forwards by driving two synchronous belts to rotate through two motors, transmission errors which are caused when the synchronous belts are driven through one motor are reduced, and pole piece conveying precision is improved.

Description

technical field [0001] The invention relates to a slicer in the field of lithium battery production, in particular to a slicer for producing laminated pole pieces. Background technique [0002] The slicers widely used in the domestic market can be roughly divided into two types: [0003] 1. A slicer for cutting pole pieces with a laser die; [0004] 2. A slicer for cutting pole pieces with a metal knife die. [0005] The basic working principle of the first type of slicer is to use the motor to drive the pole piece to a fixed length, the laser knife die is installed on the punching machine to cut off the pole piece, and the cut pole piece and waste materials are transported to the outside of the punching machine through the recycled PET film. The formed pole piece is transported to the inside of the material box, and the waste material continues to be transported forward with the PET film and falls into the waste material collection place. The advantage of this type of sl...

Problems solved by technology

[0007] For a long time, affected by many aspects such as design, function, material, processing, cost, etc., domestic slicers have not made much progress in many aspects such as production efficiency, burrs and powder loss of finished pole pieces, dimensional accuracy of pole pieces, and convenience of operation. Therefore, how to improve the production efficiency of the slicer, reduce the burr and powder drop of the pole piece, ensure the dimensional accuracy of the pole piece, and improve the convenience of machine operation have become the bottleneck problems of the slicer in the field of lithium battery production in China today.
