Problems solved by technology

[0004] (1) When the copper foil is cut equidistantly, the two sections of copper foil to be cut are easy to be cut unevenly, resulting in different synchronous widths of the two sections, and most equipment cannot integrate the surface of the two sections of copper foil after cutting Grinding
[0005] (2) The edge of the copper foil cut after the two sections will be uneven, resulting in poor subsequent use effect;

Embodiment Construction

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0033] Such as Figure 1 to Figure 6 Shown, a lithium battery copper foil production process, which uses a rolling press equipment, the punching and rolling pressing equipment includes a base 1, a cutting device, a pressing device, a winding device, using the above lithium battery copper foil production The specific method of processing technology is as follows:

[0034] S1. Copper foil placement: manually place the uncut copper foil on the two adjustment frames 21;

[0035] S2. Copper foil slitting: Tongyan copper foil passes through the cutting knife 24 to make the copper foil be cut into two equidistant copper foils;

[0036] S3. Copper foil pressing: when the two cut copper foils pass through the I-shaped frame 34, the depressions on both side...

Abstract

The invention relates to a lithium battery copper foil production treatment process. Winding and pressing equipment is used, and the winding and pressing equipment comprises a base, a cutting device,a pressing device and a winding device. The cutting device is fixedly installed on the upper surface of the base, the pressing device fixedly connected with the base is arranged on the front side of the cutting device, and the winding device connected with the base is arranged on the front side of the pressing device. By arranging the cutting device, equal-interval slitting of copper foil is achieved, a grinding rotating shaft rotates relatively to grind the upper end face and the lower end face of the copper foil in the middle of the grinding rotating shaft, and cutting and grinding are integrated for operation. A pressing plate is driven by a pressing motor to move to press a copper foil notch, so that irregularity caused by the notch is pressed and smoothened during cutting; and two sections of the copper foil are synchronous wound after cutting of the copper foil through the winding device, and the working efficiency is higher.

Description

technical field [0001] The technical field of lithium battery copper foil processing of the present invention is specifically a production and treatment process of lithium battery copper foil. Background technique [0002] Lithium battery copper foil is an important material for the manufacture of copper clad laminates (CCL), printed circuit boards (PCB), and lithium-ion batteries. In today's rapid development of the electronic information industry, electrolytic copper foil is known as electronic product signal and power transmission, The "neural network" of communication. Since 2002, the production value of printed circuit boards in my country has entered the third place in the world, and as the substrate material of PCB --- copper clad laminate has also become the third largest producer in the world, which also makes my country's electrolytic copper foil industry In recent years, it has developed by leaps and bounds. Electrolytic copper foil is an important material for th...
