Description

Technical Field

[0001] This utility model relates to the field of lithium battery cap pressure welding technology, specifically an anti-tipping lithium battery cap pressure welding machine. Background Technology

[0002] The cap welding of lithium batteries is a crucial step in the lithium battery manufacturing process. It involves connecting the lithium battery and the cap together through pressure welding. The cap protects the lithium battery during charging, providing safety protection and making the lithium battery safer to use, thus protecting the user. Therefore, a lithium battery cap welding machine is needed to weld the lithium battery and the cap together.

[0003] An investigation revealed that a Chinese utility model patent discloses a lithium battery cap pressure welding device (publication number: CN216151429U), comprising a control box, an operating table, pressure welding equipment, and an annular transparent baffle. The control box is movably connected to the inside of the operating table, and the pressure welding equipment is fixedly connected to the top right side of the operating table. The annular transparent baffle is fixedly connected to the surface of the pressure welding equipment. The pressure welding equipment includes a base plate, a pressure welding table, a pressure welding machine, and a support column. The bottom of the base plate is fixedly connected to the top of the operating table, the top of the base plate is movably connected to the pressure welding table, the support column is fixedly connected to the rear of the top of the base plate, and the pressure welding machine is fixedly connected to the front of the support column.

[0004] Although the aforementioned patent eliminates the need for manual docking compared to existing technologies, reducing manual operation steps and labor intensity for workers, the inability to secure the lithium battery during pressure welding to the cap can lead to the battery tipping over. This necessitates manual intervention to lift the tipped lithium battery before it can be welded to the cap, thus slowing down the welding process and reducing lithium battery production efficiency.

[0005] Therefore, this utility model provides a lithium battery cap welding machine to prevent tipping, in order to solve the above problems. Utility Model Content

[0007] This invention provides an anti-tipping lithium battery cap welding machine, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery cap pressure welding machine for preventing tipping, comprising a processing platform, a pressure welding assembly on the top of the processing platform, a connecting rod slidably connected below the pressure welding assembly inside the processing platform, a positioning block fixedly connected to the end of the connecting rod away from the processing platform, a first spring fixedly connected to the inner wall of the positioning block, the end of the first spring away from the positioning block being fixedly connected to the inner wall of the processing platform, the connecting rod being inserted through the inner ring of the first spring, a first gear rotatably connected to the top of the processing platform, a motor for driving the first gear to rotate being provided at the bottom of the processing platform, a placement slot for placing the lithium battery being opened on the top of the first gear, and a compression ball in contact with the positioning block being fixedly connected to the top of the first gear.

[0010] As a preferred technical solution of this application, the top of the processing platform is rotatably connected to a second gear that meshes with the first gear, and the top of the second gear is fixedly connected to a lever.

[0011] As a preferred technical solution of this application, a placement block is fixedly connected to the top of the processing platform, and the inner cavity of the placement block is connected to a discharge pipe.

[0014] As a preferred technical solution of this application, a second spring is fixedly connected to the outer wall of the push block, and the end of the second spring away from the push block is fixedly connected to the inner wall of the placement block.

[0015] As a preferred technical solution of this application, the actuating rod contacts the push block, and the squeezing ball is arc-shaped and adapted to the outer wall of the positioning block.

[0016] (III) Beneficial Effects

[0017] This invention, through the arrangement of a first gear, placement slots, extrusion balls, positioning blocks, connecting rods, and a first spring, allows the individual extrusion balls at each placement slot on the first gear to contact the positioning block first when the motor drives the first gear to rotate, causing it to move outward. This enables the lithium battery in the placement slot to rotate smoothly to the position directly below the pressure welding assembly. Simultaneously, when the lithium battery rotates to the position directly below the pressure welding assembly, the extrusion balls lose contact with the positioning block, allowing the positioning block to reset and fix the lithium battery using the elastic force of the connecting rod and the first spring. This provides a fixed effect to prevent the lithium battery from tipping over, thus eliminating the need for manual support and indirectly increasing the pressure welding speed between the lithium battery and the cap, thereby improving the production efficiency of the lithium battery.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides an anti-tipping lithium battery cap welding machine, such as... Figure 1-7 As shown, the pressure welding machine includes a processing platform 1, a pressure welding assembly 2 is provided on the top of the processing platform 1, a connecting rod 3 is slidably connected below the pressure welding assembly 2 inside the processing platform 1, a positioning block 4 is fixedly connected to the end of the connecting rod 3 away from the processing platform 1, a first spring 5 is fixedly connected to the inner wall of the positioning block 4, the end of the first spring 5 away from the positioning block 4 is fixedly connected to the inner wall of the processing platform 1, the connecting rod 3 is inserted through the inner ring of the first spring 5, a first gear 6 is rotatably connected to the top of the processing platform 1, a motor 7 for driving the first gear 6 to rotate is provided at the bottom of the processing platform 1, a placement slot 8 for placing lithium batteries is opened on the top of the first gear 6, and an extrusion ball 9 that contacts the positioning block 4 is fixedly connected to the top of the first gear 6.

[0029] Specifically, when it is necessary to fix the lithium battery to facilitate subsequent pressure welding with the cap, firstly, multiple lithium batteries are placed in multiple placement slots 8, and then the motor 7 is started. After the motor 7 starts, it drives the first gear 6 to rotate through the output shaft, so that the lithium batteries in the multiple placement slots 8 on the first gear 6 are in a rotating state. The extrusion ball 9 at each placement slot 8 can rotate first to contact the positioning block 4. When the extrusion ball 9 contacts the positioning block 4, the extrusion ball 9 can use its arc surface to squeeze the positioning block 4, causing the positioning block 4 to move outward through the connection of the connecting rod 3. After the positioning block 4 moves outward, the lithium battery in the placement slot 8 can continue to rotate without being blocked by the positioning block 4, so that the lithium battery can rotate smoothly to the position directly below the pressure welding assembly 2, which is convenient for subsequent pressure welding with the cap using the pressure welding assembly 2.

[0030] Simultaneously, when the lithium battery rotates to the position corresponding to the pressure welding component 2, the compression ball 9 means that it has lost its compression on the positioning block 4. After the positioning block 4 is no longer compressed by the compression ball 9, it can be reset by the elastic force of the connecting rod 3 and the first spring 5. After the positioning block 4 is reset, it can compress and fix the lithium battery, preventing the lithium battery from easily tipping over during subsequent pressure welding, which would affect the accuracy of the pressure welding between the lithium battery and the cap. This ensures the quality of the pressure welding between the lithium battery and the cap. Furthermore, when the lithium battery has an anti-tipping effect, there is no need to manually lift the lithium battery, thereby indirectly increasing the pressure welding speed between the lithium battery and the cap and indirectly improving the production efficiency of the lithium battery.

[0031] The top of the processing platform 1 is rotatably connected to a second gear 10 that meshes with the first gear 6, and the top of the second gear 10 is fixedly connected to a lever 11.

[0032] A placement block 12 is fixedly connected to the top of the processing platform 1, and a discharge pipe 13 is connected to the inner cavity of the placement block 12.

[0033] An overlap block 14 is fixedly connected inside the discharge pipe 13. The overlap block 14 is made of rubber.

[0034] The placement block 12 has a pusher 15 inside, and the bottom of the placement block 12 has a through hole 16 for the pusher 15 to slide into.

[0035] A second spring 17 is fixedly connected to the outer wall of the push block 15, and the end of the second spring 17 away from the push block 15 is fixedly connected to the inner wall of the placement block 12.

[0036] The lever 11 contacts the push block 15, and the compression ball 9 is arc-shaped and adapted to the outer wall of the positioning block 4.

[0037] Specifically, when the lithium battery is in the placement slot 8, the cap can be simultaneously placed into the placement block 12. As the motor 7 drives the first gear 6 to rotate, gradually completing the lithium battery fixing process, the second gear 10, which meshes with the first gear 6, drives the actuating rod 11 to rotate. When the actuating rod 11 rotates, it moves the push block 15, causing the push block 15 to push the cap in the placement block 12 towards the pressure welding assembly 2. After the lithium battery and the cap are in the same position, they can be bonded together using the pressure welding assembly. 2. Perform pressure welding to ensure that the pressure welding process between the cap and the lithium battery is synchronized. After the lithium battery is fixed, the cap moves to the same position as the lithium battery. At the same time, when the actuating rod 11 rotates to a certain angle, it loses its actuation on the push block 15. The push block 15 can be reset by the second spring 17 when it is not actuated by the actuating rod 11. After the push block 15 is reset, the actuating rod 11 can rotate to a certain angle to continue actuating the push block 15 to push the cap to move, so as to achieve the purpose of automating the loading of the cap.

[0038] When the cap moves into the discharge pipe 13, it can be placed on the overlap block 14. At this time, the pressure welding assembly 2 can be used to press the cap on the overlap block 14 into contact with the lithium battery and perform pressure welding. The overlap block 14 is made of rubber, so when the pressure welding assembly 2 presses the cap, the cap can be squeezed out of the overlap block 14 and smoothly contact the lithium battery. The plasticity of the rubber of the overlap block 14 allows it to recover quickly. It can be used for the placement of the cap, and it can also be adjusted to allow the cap to continue to move downwards to contact the lithium battery. The limiting space provided by the discharge pipe 13 ensures that the cap will not shift during the downward movement, ensuring that the cap and the lithium battery are in the same position, preventing the cap from shifting and reducing the pressure welding quality between the cap and the lithium battery. The through hole 16 provides space for the push block 15 to contact the toggle lever 11, so that the push block 15 can contact the toggle lever 11 from the through hole 16, and the push block 15 can also move smoothly.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
