Description

Technical Field

[0001] The present invention relates to the technical field of new energy batteries, and in particular to an automatic cutting and winding machine for lithium batteries and an intelligent control method for the automatic cutting and winding. Background Art

[0002] Lithium-ion batteries are a new generation of green high-energy batteries with excellent performance. They 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, low self-discharge, and many cycles. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, low self-discharge, and many cycles. In recent years, the lithium-ion battery manufacturing industry has developed rapidly, and the process quality requirements for manufacturing battery cores have been continuously improved. The processing steps of lithium batteries mainly include positive electrode ingredients, negative electrode ingredients, coating, positive electrode sheeting, negative electrode sheeting, positive electrode sheet preparation and negative electrode sheet preparation, winding, shelling, rolling grooves, battery core baking, liquid injection, super welding capping and performance testing;

[0003] Before winding the battery cell, a cutting device is needed to cut the pole pieces, diaphragms and other materials before winding. In the lithium battery manufacturing process, the cutting and winding of key materials such as pole pieces and diaphragms is one of the core links, and its quality and efficiency directly affect the overall performance and production cost of lithium batteries. Traditional cutting and winding processes often rely on manual operations, 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 automated and intelligent cutting and winding equipment.

[0004] However, there are still some problems in the development and application of automated cutting and winding equipment. For example, after cutting, the pole pieces, diaphragms and other materials may have scratches, creases and other defects. If these defective materials continue to be processed, it will seriously affect the quality of the finished lithium battery. In addition, when the feeding mechanism discharges the material, how to prevent the material from falling off from the bottom of the suction cup due to excessive adsorption, resulting in poor material discharge, is also a problem that automated cutting and winding equipment needs to overcome.

[0005] At the same time, in the process of realizing the intelligent control of automatic cutting and winding, a series of technical challenges are faced. First of all, how to realize the fully automated operation from feeding, winding, cutting to unloading to improve production efficiency is an urgent problem to be solved. The traditional operation method requires manual participation in multiple links, which is not only time-consuming and labor-intensive, but also prone to errors. Therefore, it is necessary to develop an intelligent control method that can integrate advanced control systems and sensor technologies to achieve fully automated operation.

[0006] Secondly, the application of intelligent control methods needs to ensure the stability and flexibility of the production process. Since there are many 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 be able to automatically adjust parameters according to production needs to adapt to different production conditions and ensure the stability and flexibility of the production process.

[0007] In addition, in order to achieve continuous optimization and improvement of the production process, a system that can automatically record each production data is needed, and can deeply mine the production data through data analysis software. Traditional data recording and analysis methods often rely on manual operations, which are 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 that can automatically record and analyze production data to find out problems in the production process and propose improvement measures.

When the vacuum suction cup device 41 moves linearly, it will drive the suction cup group 411 to contact the outside of the machine tool frame 1, and then drive the rack group 48 to move, and then the driving gear 47 is rotated, and finally the threaded rod 45 is driven to descend, and then the push plate 413 is driven to move, and the material fixed by the vacuum suction cup device 41 is pushed. At this time, if the outer surface of the material is folded The marks and scratches on the material will cause the vacuum suction cup device 41 to be unstable, and then the push plate 413 will push the material away. At this time, the descending push plate 413 drives the T-shaped arm 414 to move together. The T-shaped arm 414 moves through the connecting rod 415, and then releases the suction cup group 411, driving the switch outside the suction cup group 411 to move, and then releases the fixation of the material with creases. At this time, the material is driven into the inside of the guide bin 43. At the same time, when the push plate 413 is close to the lifting mechanism 44, the lifting mechanism 44 is driven to rise by magnetic force to buffer the falling material.

[0072] The first conveyor belt 5 transports the qualified materials after cutting to the outside of the second conveyor belt 61, and after passing the detection of the detection camera group 62 and the position correction of the limit plate 63 and the correction plate 64, it is finally driven by the traction device 67 to the bottom of the gluing device 68 for gluing. The glued materials are driven by the control arm 71 to the outside of the guide conveyor 72, and the materials are wound by the winding device 73. Finally, the processed materials are placed on the top of the load-bearing plate 77. After passing the detection of the detection table 76, the materials are discharged through the discharge slide 78 to complete the overall processing steps.
