[0019] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] When processing Topcon cells, an oxidation furnace is required. The oxidation furnace forms a required oxide film on the surface of the raw materials of the processed topcon cells under a certain temperature and atmosphere reaction. However, during the use of the oxidation furnace for processing topcon cells, the raw materials are mostly pushed into the oxidation furnace manually, which is troublesome and has low work efficiency.

[0021] Example

[0022] The existing device solves the problem of automatic loading, but the baffles on both sides of the above-mentioned device technical solution and the L-shaped plate on the outside form a semi-enclosed structure. Due to the shielding effect of the above-mentioned structure, it is inconvenient for workers or robotic arms to put the battery cells on the loading platform, which causes inconvenience. Figure 1-Figure 3 The embodiment provides a raw material feeding device for an oxidation furnace for processing topcon battery cells, comprising an oxidation furnace body 1 and a feed port 2 opened on the oxidation furnace body 1, and a mounting plate 3 is fixedly installed below the feed port 2 on the oxidation furnace body 1.

[0023] like Figure 1-Figure 3 As shown, obstructions will block the sight of workers or robotic arms, making it difficult for them to accurately place the battery cells in the designated position, increasing the difficulty of operation, requiring extra time and effort to complete the task, and then leading to processing position deviation, thereby affecting the processing accuracy and the quality of the final product. Therefore, in order to enable workers or robotic arms to place the battery cells without obstacles and accurately position and center them, the following settings are made: a correction mechanism 4 for pushing the battery cells to the top center position of the mounting plate 3 is provided at one end of the mounting plate 3 away from the oxidation furnace body 1, and the correction mechanism 4 includes a baffle motor 41 fixedly mounted on the outer end of the mounting plate 3, and side baffles 42 are rotatably installed on both sides of the mounting plate 3. Before the loading device works, the side baffles 42 on both sides are in a horizontal state and do not hinder the placement of the battery cells, so that workers or robotic arms can easily and unobstructedly place the battery cells on the mounting plate 3, significantly improving the convenience of operation before loading. The side baffle 42 is connected to the baffle motor 41. Driven by the baffle motor 41, the side baffle 42 can push the battery cell to the center position of the middle of the mounting plate 3, ensuring accurate positioning of the loading process, which is beneficial to uniform heating of the battery cell in the oxidation furnace body 1 and improving the uniformity and quality of the oxide film formation.

[0024] refer to Figure 2 As shown, when the hardness of the topcon battery cell material does not match the hardness of the side baffle 42 and the mounting plate 3, the risk of damage caused by friction and extrusion will increase, especially when the surface of the battery cell is fragile or easily scratched, it is easy to be damaged by the friction of the hard surface. Therefore, in order to avoid the wear or damage of the battery cell caused by friction and extrusion during the loading process, thereby affecting the integrity of the battery cell, the following settings are made: the upper surfaces of the side baffle 42 and the mounting plate 3 are provided with a plush rubber plate 6, and the plush rubber plate 6 is a plate-like structure with flocked rubber material on the upper surface. The rubber material and flocked surface of the plush rubber plate 6 provide good buffering for the battery cell, effectively avoiding the wear or damage of the battery cell caused by friction and extrusion during the loading process, protecting the integrity of the battery cell, and reducing production losses; the flocked surface of the plush rubber plate 6 not only provides buffering, but also has good flexible contact and anti-slip properties, which can effectively prevent the battery cell from sliding or deflecting during the pushing process, ensuring the stability and reliability of the loading process.

[0025] refer to Figure 1-Figure 3 As shown, one end of the mounting plate 3 away from the oxidation furnace body 1 is provided with a loading mechanism 5 for automatically pushing the battery cell from the initial position to the feed port 2, and the loading mechanism 5 includes a power motor 51 fixedly mounted on the outer end of the mounting plate 3, a threaded rod 52 is fixedly mounted on the output end of the power motor 51, and a slider 53 is threadedly connected to the outer wall of the threaded rod 52, and an intermediate guide groove 54 is opened in the middle of the mounting plate 3, and the slider 53 slides inside the intermediate guide groove 54, and a push block 55 is fixedly mounted on the upper end of the slider 53 to push the battery cell to move into the feed port 2 to complete the loading of the battery cell, the power motor 51 drives the threaded rod 52 to rotate, the rotation of the threaded rod 52 drives the slider 53 to move, the movement of the slider 53 drives the push block 55 to move, and the movement of the push block 55 pushes the battery cell to move into the feed port 2, thereby completing the loading process of the battery cell, which can greatly reduce the burden of manual operation and improve work efficiency.

[0026] Since the correction mechanism 4 and the feeding device 5 adopt the design of rotatable side baffle 42, slider 53-threaded rod 52 transmission structure, etc., each component is relatively independent and easy to disassemble and assemble, which is convenient for daily maintenance and troubleshooting of the device, and improves the overall convenience and maintenance efficiency of the device.

[0027] The working principle of the utility model is as follows: when working, the battery cell is first placed on the mounting plate 3, and then the baffle motor 41 is actuated to drive the side baffle 42 to rotate. The rotation of the side baffle 42 allows the battery cell to slide on the side baffle 42, and then the battery cell is pushed to the center position. The plush rubber plate 6 plays a buffering role for the battery cell to prevent the battery cell from being worn, squeezed and damaged during the pushing process or the pushing process of the side baffle 6. Then the power motor 51 is actuated to drive the threaded rod 52 to rotate, and the rotation of the threaded rod 52 drives the slider 53 to move. The movement of the slider 53 drives the push block 55 to move, and the push block 55 moves to push the battery cell into the feed port 2, thereby completing the loading process of the battery cell.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
