Description

Technical Field

[0001] This invention belongs to the field of lithium battery processing technology, and in particular, it is an improved structure of the wound electrode flyband. Background Technology

[0002] The winding equipment is a KAIDO winding machine. During the production process, the KAIDO winding machine is prone to problems such as the electrode bending and shifting to one side after being cut, eventually being blocked by the cutter box outlet, resulting in the electrode not being inserted into the correct position and causing the flying strip problem, which seriously reduces production efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an improved structure for wound electrode flying strips.

[0004] The purpose of this invention is to provide an improved structure for the winding electrode flyband, wherein the cutting box guide rail is tilted at an angle of 75°, the length of the lower guide block guide rail of the cutting box is extended by 9.5 mm, and the lower guide block of the cutting box does not exceed the lower cutting edge of the cutting blade.

[0005] The present invention has the following advantages: by optimizing the lower guide block of the winding electrode cutter box, the problem of flying strip production in KAIDO winding machines is solved, and production efficiency is greatly improved. Attached Figure Description

[0006] Figure 1 This is a design drawing of the lower guide block of the cutter box of the present invention. Detailed Implementation

[0007] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0008] like Figure 1 As shown, an improved structure for the winding electrode flyband, suitable for KAIDO winding machines, is proposed. This involves increasing the tilt angle of the cutter box guide rail to 75°, extending the length of the lower guide block guide rail of the cutter box by 9.5mm, and installing the lower guide block of the cutter box together with the cutter box at the cutting position of the winding machine. The lower guide block of the cutter box must not exceed the lower cutting edge of the cutter. After these optimizations, during the winding process, after the electrode is cut, it will smoothly insert into the lower EPC wheel along the lower guide block of the cutter box, achieving continuous production.

Claims
