The utility model discloses a special oven for the lithium battery industry, which can dry lithium battery-related products, not only block products, but also sheet products, improving drying efficiency, while preventing the plate from being easily disassembled, and maximizing the use of the oven's internal space, showing good prospects for use.

[0003] The above technical solution is provided with a support block and a placement plate, and the placement plate is taken out from the inside of the oven. Then, the block products related to the lithium battery are placed on the surface of the placement plate, and the placement plate and the products are pushed into the oven together, and then the product is dried. After the drying is completed, the product and the placement plate are taken out together, and the surface product can be removed. However, the above technical solution still has certain defects. For example, the above equipment places the block products related to the lithium battery on the surface of the placement plate, but the equipment will cause the placement plate to shake during operation, and then the batteries on the placement plate will collide with the inner wall of the oven or other components. Then, the lithium battery is usually in a relatively fragile state during the baking process. The collision may cause the battery shell to rupture, internal short circuit or electrolyte leakage, etc., thereby reducing the practicality of the equipment. Utility Model Content

[0033] Furthermore, when using the device, it is started by connecting an external power supply. First, the box door 2 is opened and the protrusions on both sides of the placement plate 8 are aligned with the placement plate groove 12 and inserted. Then, the force generated by the return spring 9 on the push block 10 causes the push block 10 to drive the limit block 16 to move in the opposite direction while the other end enters the inside of the first limit block groove 15, thereby limiting the placement plate 8 to prevent it from moving or shaking. Then, the lithium battery-related block products are placed on the surface of the placement plate 8, and then the box door 2 is closed to heat the oven 1 through the heating plate 6 while drying the lithium battery-related block products. Then, the output end of the motor 3 is rotated to drive the threaded rod 14 to rotate and drive the movable seat 13 to move from the inside of the oven 1 while driving the placement frame 7 out of the inside of the oven 1. Then, the push block 10 is pushed to move in the opposite direction to drive the return spring 9 to contract while driving the limit block 16 to move in the opposite direction. Then, the limit block 16 moves in the opposite direction to make the outer wall of its other end disengage from the inside of the first limit block groove 15, and then the placement plate 8 can be removed from the placement frame 7 by pulling it.

[0034] The cams 16 on both sides of the placing plate 8 are aligned with the placing plate grooves 12 and inserted into the placing plate grooves 12 by the limit device, and then the force generated by the return spring 9 on the pushing block 10 causes the pushing block 10 to drive the limit block 16 to move in the opposite direction while the other end enters the inside of the first limit block groove 15, thus limiting the placing plate 8 and preventing it from moving or shaking, thereby avoiding the placing plate 8 from shaking during operation, effectively improving the practicality and safety of the equipment, and at the same time avoiding the battery from colliding with the inner wall of the oven or other components, thereby protecting the battery, and then pushing the pushing block 10 to move in the opposite direction to drive the return spring 9 to contract and drive the limit block 16 to move in the opposite direction, and then the limit block 16 moves in the opposite direction to make the outer wall of the other end disengage from the inside of the first limit block groove 15, and then pulling the placing plate 8 to remove it from the placing frame 7, which is convenient for disassembling the placing plate 8, effectively improving the work efficiency of the staff, and at the same time improving the maintenance and inspection efficiency of the placing plate 8.

[0035] Working principle: first open the box door 2 and align the protrusions on both sides of the placement plate 8 with the placement plate slots 12 and insert them. Then, the return spring 9 exerts a force on the push block 10 to make the push block 10 drive the limit block 16 to move in the opposite direction while the other end enters the inside of the first limit block slot 15. This limits the placement plate 8 to prevent it from moving or shaking. Then, the lithium battery related block products are placed on the surface of the placement plate 8. Then, close the box door 2 and heat the oven 1 through the heating plate 6 to dry the lithium battery related block products. Then, the output end of the motor 3 rotates to drive the threaded rod 14 to rotate and drive the moving seat 13 to move from the inside of the oven 1 while driving the placement frame 7 out of the inside of the oven 1. Then, push the push block 10 to move in the opposite direction to drive the return spring 9 to contract while driving the limit block 16 to move in the opposite direction. Then, the limit block 16 moves in the opposite direction to make the outer wall of its other end disengage from the inside of the first limit block slot 15. Then, pull the placement plate 8 to remove it from the placement frame 7.
