Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically a hot pressing device for lithium battery production. Background Technology

[0002] A lithium-ion battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The working principle of a lithium-ion battery is based on a redox reaction, specifically involving the movement of lithium ions between the positive and negative electrodes. During charging, lithium ions are released from the positive electrode (which usually contains lithium compounds), move through the electrolyte solution to the negative electrode (which is usually made of carbon material), and embed themselves there.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: In the production of lithium batteries, it is necessary to hot press the lithium batteries. When operating a traditional hot press, the entire process requires workers to manually complete the loading and unloading operations. Since traditional hot presses lack loading and unloading mechanisms, workers need to manually place the lithium batteries during operation. This can easily lead to uneven loading due to non-standard battery placement. Therefore, a hot pressing device for lithium battery production is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A hot pressing device for lithium battery production, comprising a body and a moving device, wherein a hot pressing part is slidably connected to the surface of the body, a control box is fixedly connected to the side wall of the body, and three buttons are fixedly connected to the surface of the body; the moving device is disposed on the surface of the body, and the moving device includes two support blocks, the side walls of the two support blocks are fixedly connected to the side wall of the body, a support rod is fixedly connected to the side wall of the support block, and a connecting block is fixedly connected to the end of the support rod away from the support block; a placement plate is slidably connected to the surface of the two support rods, the placement plate is located directly below the hot pressing part, and multiple support rollers are located between the two support blocks, allowing the placement plate to slide on the support rod surface on the support blocks and the connecting block. The placement plate slides to the bottom of the hot pressing part, and then the hot pressing part is activated to hot press the lithium battery. By setting the support blocks, support rods, connecting blocks, and placement plate, multiple lithium batteries can be conveniently hot-pressed, and the lithium batteries can also be conveniently fixed.

[0006] Preferably, a fixing block is fixedly connected to the side wall of the support block near the support roller. The side wall of the fixing block and the side wall of the support roller are rotatably connected. The support roller rotates on the side wall of the fixing block. By setting the fixing block and the support roller, the placement plate can be supported.

[0007] Preferably, a movable frame is fixedly connected to the side wall of the placement plate. When it is necessary to move the placement plate, the movable frame is pushed to move the placement plate. The placement plate can be easily operated by setting the movable frame.

[0008] Preferably, the movable frame and the inner walls of the two support blocks are threaded with insert rods. After the movable frame is moved to a suitable position, the insert rods are rotated to the inner walls of the two support blocks and the movable frame, and the insert rods can restrict the position of the movable frame.

[0009] Preferably, a sliding hole is provided on the surface of the placement plate near the support rod. The inner wall of the sliding hole of the placement plate is slidably connected to the surface of the support rod. When the placement plate moves, the placement plate will slide on the surface of the support rod through the sliding hole. The opening of the sliding hole can facilitate the sliding of the placement plate on the surface of the support rod.

[0010] Preferably, a protective device is provided on the surface of the body near the three buttons. The protective device includes a fixing frame, the side wall of the fixing frame is fixedly connected to the surface of the body, and three protective blocks are rotatably connected to the surface of the fixing frame. The protective blocks are fitted onto the surface of the buttons, and a limit post is fixedly connected to the surface of the fixing frame near the protective blocks. The protective blocks rotate to the surface of the buttons. By setting the fixing frame, protective blocks and limit posts, the buttons can be protected and the accidental button presses can be reduced.

[0011] Preferably, a locking block is fixedly connected to the upper surface of the protective block, and a locking hole is opened on the surface of the machine body near the locking block. The locking block is inserted into the inner wall of the locking hole of the machine body. When the protective block rotates, the protective block drives the locking block to move and the locking block is inserted into the inner wall of the locking hole. The angle of the protective block can be limited by setting the locking block.

[0012] Preferably, the locking block is a rubber block, and the vertical cross-section of the locking block forms an "L" shape. When the locking block rotates, it will be squeezed into the inner wall of the locking hole. By setting the locking block as a rubber block, the friction between the locking block and the locking hole can be increased.

[0013] The advantages of this utility model are:

[0014] 1. When hot pressing lithium batteries is required, the lithium battery is placed on the inner surface of the placement plate, and then the moving frame is pushed to move the placement plate. The placement plate moves on the surface of the support roller, and the support roller rotates on the surface of the fixed block. When the placement plate moves, it slides on the surface of the support rod through the sliding hole. The support rod is fixed to the machine body by the support block and the connecting block. After the placement plate moves to the appropriate position, the insertion rod is rotated to the inner wall of the two support blocks and the moving frame. Then the hot pressing unit is started to hot press the lithium battery. After hot pressing is completed, the insertion rod is rotated out from the support block and the placement plate. Then the moving frame is pulled to move the placement plate away from the machine body. Then the lithium battery is removed. By setting up the whole device, multiple lithium batteries can be easily fixed, and the placement of lithium batteries can be standardized, reducing the situation of uneven feeding.

[0015] 2. When the button is not needed, the present invention pushes the protective block to rotate on both sides of the fixed frame and the limiting post. When the protective block rotates, it will drive the locking block to move. The protective block will fit on the surface of the button, and the locking block will be inserted into the inner wall of the locking hole. By setting the entire device, the button can be protected and the accidental button touch can be reduced. Attached Figure Description
