Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery technology, specifically to a stacked lithium battery feeding device. Background Technology
[0002] With the increasing emphasis on global energy structure transformation and environmental protection, the new energy industry is developing rapidly. Lithium batteries, as a key technology in the new energy field, are seeing their application scope expand and market demand continue to grow. In the lithium battery manufacturing process, battery forming and stacking technologies are core aspects affecting battery performance and cost. The basic structure of a lithium battery mainly includes a positive electrode, negative electrode, electrolyte, separator, and casing. Its working principle is to store and release electrical energy through a chemical reaction between the positive and negative electrodes. Stacking technology is the technique of stacking the positive and negative electrode sheets and separator materials into a single battery cell. Compared to the traditional wound battery production process, it features high energy density, good safety, long cycle life, and high flexibility. In the production process of stacked batteries, the positive and negative electrode materials need to be cut into specified specifications, and then the cut electrode sheets are transferred to the stacking station by a feeding mechanism to complete the stacking. Because the positive and negative electrode sheets are very thin, the coating of the electrode sheets is easily damaged during the transfer process, affecting battery performance. To ensure safe and efficient production, this utility model designs a lithium battery stacking feeding device. Utility Model Content

This reduces unnecessary intermediate transfer steps, achieves efficient production, and reduces accidental damage to the electrode products.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a stacked lithium battery feeding device, comprising a base plate, a hopper, fixing rods, a cylinder fixing plate, a material preparation platform, and cylinder electrode sheets.

[0005] Preferably, the hopper includes a hopper support and a hopper baffle, with a lower cylinder installed at the bottom of the hopper support and a hopper baffle installed on the outside of the hopper support.
[0006] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonable. The cut electrode sheets are stacked into the feeding bin, then picked up by the suction cup and placed on the preparation table.

[0012] Reference Figure 1-3 This specific embodiment adopts the following technical solution: A stacked lithium battery feeding device includes a base plate 1, a hopper 2, fixing rods 3, a cylinder fixing plate 4, a preparation platform 5, and cylinder electrode sheets 6. Multiple fixing rods 3 are arranged on the base plate 1, and the hopper 2 is arranged inside the fixing rods 3. A fixing plate is arranged on the top of the fixing rods 3, and multiple cylinder fixing plates 4 are arranged on the fixing plate. Multiple stroke cylinders 7 are fixed on the cylinder fixing plates 4. The stroke cylinders 7 are connected to a slide rail assembly 8. An upper cylinder 9 is connected below the slide rail assembly 8 and is connected to a suction cup 10. The preparation platform 5 and the hopper 2 are arranged below the suction cup 10, and the cylinder electrode sheets 6 are placed inside the hopper 2.
