Description

TECHNICAL FIELD

[0001] The application relates to the technical field of new energy batteries, in particular to a lithium battery automatic cutting and winding machine and an intelligent control method for automatic cutting and winding. BACKGROUND

[0002] Lithium ion batteries are a new generation of green high-energy batteries with excellent performance, and have become one of the focuses of high-tech development. Lithium ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, little self-discharge, and many cycle times. In recent years, the lithium ion battery manufacturing industry has developed rapidly, and the process quality requirements for manufacturing battery winding cores have been continuously improved. The processing steps of lithium batteries mainly include positive electrode material preparation, negative electrode material preparation, coating, positive electrode sheet preparation, negative electrode sheet preparation, positive electrode sheet preparation and negative electrode sheet preparation, winding, shell insertion, groove rolling, core baking, liquid injection, super-welding cover cap, and performance testing, etc.

[0003] Among them, before winding, the cutting device needs to be used to cut the materials such as electrode sheets and diaphragms, and then the winding processing is carried out. In the lithium battery manufacturing process, the cutting and winding of key materials such as electrode sheets and diaphragms are one of the core links, and their quality and efficiency directly affect the overall performance and production cost of lithium batteries. The traditional cutting and winding process often relies on manual operation, and there are problems such as low production efficiency, low precision, and unstable quality. In order to solve these problems, the industry has begun to explore automatic and intelligent cutting and winding equipment.

[0004] However, there are still some problems in the research and application of automatic cutting and winding equipment. For example, the electrode sheets, diaphragms and other materials after cutting may have scratches, folds and other defects. If these defective materials continue to be processed, it will seriously affect the quality of the finished lithium battery, and how to avoid the materials from being unable to fall off from the bottom of the suction cup due to strong adsorption force when the feeding mechanism discharges the materials, resulting in poor discharging, is also a difficult problem that needs to be overcome in the automatic cutting and winding equipment.

[0005] At the same time, in the process of realizing intelligent control of automatic cutting and winding, a series of technical challenges are faced. First of all, how to realize full automation from feeding, winding, cutting to discharging to improve production efficiency is a problem that needs to be solved. The traditional operation method needs manual participation in multiple links, which not only consumes time and effort, but also is prone to errors. Therefore, an intelligent control method that can integrate advanced control systems and sensor technologies is needed to realize full automation.

[0006] Secondly, the application of intelligent control methods needs to ensure the stability and flexibility of the production process. Due to the existence of various variables and uncertain factors in the production process of lithium batteries, such as material properties, equipment status, production environment, etc., the intelligent control method needs to automatically adjust the parameters according to the production requirements to adapt to different production conditions, so as to ensure the stability and flexibility of the production process.

[0007] In addition, in order to realize the continuous optimization and improvement of the production process, a system capable of automatically recording each production data is needed, and the production data can be deeply mined through data analysis software. Traditional data recording and analysis methods often rely on manual operation, which is not only inefficient, but also difficult to find bottlenecks and problem points in the production process. Therefore, it is necessary to develop an intelligent control system capable of automatically recording and analyzing production data to find out the problems in the production process and propose improvement measures.

The cut material is driven to move by suction force and moved to the top of the first conveying belt 5 and released. When the vacuum suction cup device 41 moves linearly, it drives the suction cup group 411 to abut against the outside of the machine tool frame 1, then drives the rack group 48 to move, drives the gear 47 to rotate, and finally drives the threaded rod 45 to descend, driving the push plate 413 to move and push the material fixed by the vacuum suction cup device 41.
