Description

Technical Field

[0001] The present invention relates to the field of lithium-ion power battery manufacturing, and in particular to a slide-type rotating stacking platform for automated battery cell stacking and a stacking and diaphragm pressing process thereof. Background Art

[0002] A lithium battery refers to a battery containing lithium in its electrochemical system, including metallic lithium, lithium alloys, lithium ions, and lithium polymers. Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium ion batteries. A lithium battery is a rechargeable battery that primarily relies on the movement of lithium ions between a positive and negative electrode. Batteries, which generally use materials containing lithium as electrodes, are the epitome of modern high-performance batteries. With China's vigorous promotion of new energy development, demand for lithium-ion power batteries is growing across various industries. The core component of a lithium-ion power battery is the battery cell, which is generally composed of alternating positive and negative electrode sheets. These cells consist of multiple alternating positive and negative electrode sheets, separated and insulated by a separator. Currently, the most technologically advanced lithium battery equipment in China is primarily in the hands of foreign equipment suppliers, and high-end lithium battery stacking equipment in China is primarily imported.

[0003] The battery cell of a lithium-ion battery is generally formed by alternating and stacking positive and negative electrodes, with an insulating separator inserted between them. Currently, the manufacturing process for battery cells includes two methods: strip lamination and single-piece lamination, depending on the separator insertion process. That is, continuous separators and single-piece separators are used for lamination. In the strip lamination process, the positive and negative electrodes are placed alternately on the lamination platform during lamination, and the strip separator is pulled back and forth above the lamination platform. After the positive or negative electrode is stacked, it is covered on the surface of the positive or negative electrode, and then the separator is cut. In this lamination method, the strip separator is stretched and pulled back and forth during the lamination process, resulting in internal stress. After cutting, the separator surface will wrinkle, affecting the quality of the battery cell. For the single-piece stacking process, the diaphragm is cut into a single-piece structure before stacking. After the positive and negative electrodes are stacked, the single-piece diaphragm is stacked on the surface of the positive electrode or the negative electrode to achieve stacking. This stacking process requires multiple diaphragm stacking, resulting in low stacking efficiency. In order to ensure the position accuracy of each stacking, the diaphragm needs to be aligned before stacking, and the stacking position accuracy is difficult to effectively guarantee.

[0004] For the above-mentioned strip stacking process, the following technical difficulties need to be solved during the automated stacking design process: During the stacking process, the continuous diaphragm strip is pulled open and the positive electrode sheet or negative electrode sheet is stacked on it, and then the diaphragm is pulled back to the above-mentioned positive electrode sheet or negative electrode sheet, and the diaphragm strip is coated back and forth along a Z-shaped path, and the electrodes of different polarities are stacked on the diaphragm one by one; based on the above stacking principle, the horizontal diaphragm that has been covered on the stacking platform needs to be pressed tightly during the left and right coating of the diaphragm to avoid it being lifted up when the film is pulled later. The traditional film pressing mechanism generally uses a cylinder to drive the suspended pressing plate to press the diaphragm from the outside of the stacking platform. In addition, since interference with the laminating movement needs to be avoided during the film pressing process, the film pressing process cannot only be pressed down from the vertical direction, but the pressing plate must also have a retraction force in the horizontal direction. To achieve this requirement, the existing film pressing device uses a cam transmission method to achieve vertical and horizontal drive. The transmission is unstable and affects the flatness of the pressing plate during film pressing. Its structural design is very complex, the force transmission path is long, and the transmission error is large. Summary of the Invention

In the natural state, the elastic force of the sealing spring (9213) is exerted on the sealing swing block (9212). 212) drives the sealing plate (9214) to press down, so that the sealing plate (9214) maintains a horizontal state and is buckled on the flexible opening to seal the flexible opening. At the flexible sealing position, the slide cylinder (928) drives the lifting slide (926) to move upward, and the lifting slide (926) drives the guide wheel (929) to push the sealing plate (9214) upward, so that the guide wheel (929) enters the upper slide (9215) from the lower slide (9216) through the flexible opening. After the guide wheel (929) completely enters the upper slide (9215), the sealing plate (9214) is automatically pulled to a horizontal state by the sealing spring (9213) so that the guide wheel (929) can roll linearly on the upper slide (9215).

7. A lamination and film pressing process for manufacturing a battery cell into a slide-type rotating lamination platform according to any one of claims 1 to 6, characterized in that: The process steps include: S1, Laminating: The diaphragm is spread horizontally and covered on the laminated support; S2. Lamination: The positive electrode sheet or the negative electrode sheet is stacked on the separator horizontally stretched on the lamination support in step S1; S3, secondary lamination: the diaphragm in the diaphragm unwinding mechanism is pulled open again and horizontally covered on the electrode stacked on the diaphragm in step S2; S4, film pressing: the diaphragm horizontally covered on the lamination support in step S1 and step S3 is pressed by the pressing plates of the film pressing assembly on the left and right sides of the lamination support; the pressing plates move in the horizontal and vertical directions to press the films; the film pressing assembly is internally provided with an upper slide and a lower slide spaced apart in the vertical direction, and the upper slide and the lower slide are horizontally arranged; the pressing plates are guided and limited by the upper slide and the lower slide when moving horizontally and vertically; one end of the upper slide and the lower slide is an open structure, and the other end of the upper slide is a flexible opening; the above-mentioned flexible opening is automatically sealed to maintain the linear motion of the pressing plates on the upper slide.
