Description

Technical Field

[0001] This utility model relates to the field of paste application technology, and more specifically, to a paste application device for battery production. Background Technology

[0002] In existing technologies, a workpiece guiding system in a paste-coating device used for battery production suffers from inconvenience during actual operation. Specifically, the workpiece is moved and positioned within the device via a guiding mechanism, but due to the complex design of the guiding structure, precise positioning and stability of the workpiece are often difficult to guarantee during operation. This not only increases the time and difficulty of workpiece loading and unloading but may also lead to workpiece displacement or deformation during production, thereby affecting the uniform coating effect and the quality of the final product.

[0003] Furthermore, the connection between the paint tank and the roller coating device is also inconvenient. In existing equipment, the connection between the paint tank and the roller coating section often requires multiple adjustments and manual operations to ensure that the paint can smoothly enter the coating area. This connection method not only increases the workload of operators but may also lead to paint waste or uneven coating, thus affecting the consistency and performance of the battery products. At the same time, cleaning and maintenance of the connection points are also relatively troublesome, and paint residue is prone to accumulate, leading to equipment malfunctions or paint contamination.

[0021] Please see Figures 1-5 A paste-coating device for battery production includes a frame 1, a stabilizing guide mechanism, a coating box clamping mechanism, and a clamping auxiliary mechanism. The stabilizing guide mechanism includes a bottom roller 2 and a guide roller 3. Multiple sets of bottom rollers 2 are mounted on the frame 1, and the guide rollers 3 are rotatably mounted on the frame 1. Side rollers 4 are installed on both sides of the top end of the frame 1. A lifting frame 5 is fixedly installed on the top end of the frame 1. A coating assembly 6 is slidably mounted on the lifting frame 5. A coating box 7 is installed on the top end of the coating assembly 6. The coating box clamping mechanism includes a quick-clamp tube 8 and an inner clamp tube 9. A locking groove 10 is opened on the side wall of the inner clamp tube 9. An insertion frame 11 is slidably mounted laterally on the side wall of the quick-clamp tube 8. A longitudinal sliding sleeve 12 is slidably mounted on the outer wall of the quick-clamp tube 8. A moving push frame 13 is installed on the longitudinal sliding sleeve 12. The moving push frame 13 pushes the insertion frame 11 into the locking groove 10, fixing the inner clamp tube 9 inside the quick-clamp tube 8.

[0022] In this embodiment, the stabilizing guide mechanism provides stable guiding support for the movement of the battery panel through the combined action of the bottom roller 2, guide roller 3, and side roller 4. The drive motor 18 drives the guide roller 3 to rotate through the transmission chain assembly 19, so that the battery panel moves smoothly along the channel formed by the bottom roller 2 and guide roller 3. At the same time, the eccentric plate 20 at the output end of the transmission chain is connected to the coating assembly 6 through the push-pull rod 21, so that the coating assembly 6 slides in a direction on the lifting frame 5 to realize the reciprocating coating action of the battery panel. The coating box locking mechanism realizes the quick connection and disassembly of the coating box 7 and the coating assembly 6 through the cooperation of the quick-lock tube 8 and the inner lock tube 9. The inner lock tube 9 is connected to the top of the coating assembly 6, and a locking groove 10 is provided on its side wall. The quick-lock tube 8 is connected to the bottom of the coating box 7. When the coating box 7 needs to be installed, the inner lock tube 9 is inserted into the quick-lock tube 8. The extension bracket 11 on the side wall of the quick-lock tube 8 automatically embeds into the locking groove 10 of the inner lock tube 9 under the action of the tension spring 24, locking the two together.

[0023] The snap-fit ​​auxiliary mechanism includes a longitudinal moving block 14 and a bidirectional positioning spring 15. Multiple sets of longitudinal moving blocks 14 are installed on one end face of the longitudinal moving sleeve 12, and the bidirectional positioning spring 15 is installed on the longitudinal moving block 14. A longitudinal moving groove 16 is opened on the outer wall of the quick-clamp tube 8, and a positioning groove 17 is opened on the longitudinal moving groove 16. Multiple sets of positioning grooves 17 are provided. The bidirectional positioning spring 15 extends into the positioning groove 17 step by step, so that the longitudinal moving sleeve 12 moves stably in the longitudinal direction.

[0024] In this embodiment, the locking auxiliary mechanism controls the longitudinal movement of the longitudinal sleeve 12 on the outer wall of the quick-lock tube 8 through the cooperation of the longitudinal moving block 14 and the bidirectional positioning spring 15. The pusher 13 installed on the longitudinal sleeve 12 can push the extension frame 11 to embed or disengage it from the locking groove 10 of the inner locking tube 9. When the longitudinal sleeve 12 moves, the bidirectional positioning spring 15 on the longitudinal moving block 14 will extend into the positioning groove 17 of the longitudinal moving groove 16 on the outer wall of the quick-lock tube 8 step by step, so that the longitudinal sleeve 12 can move stably in segments and provide precise locking control.

[0025] Please see Figures 1-5 As a supplementary embodiment of a battery production paste-coating equipment with a stabilizing guide mechanism, a coating box clamping mechanism, and a clamping auxiliary mechanism: A drive motor 18 is installed on the frame 1. A transmission chain assembly 19 is installed at the output end of the drive motor 18. The output end of the transmission chain assembly 19 is connected to the guide roller 3. An eccentric plate 20 is installed at the output end of the transmission chain. The eccentric plate 20 is rotatably mounted on the frame 1. A push-pull rod 21 is rotatably connected between the eccentric plate 20 and the coating assembly 6. A guide rod 22 is installed at the bottom end of the coating box 7. A guide sleeve 23 is installed at the top end of the coating assembly 6. The top end of the coating assembly 6 is connected to the inner clamping tube 9. The bottom end of the coating box 7 is connected to the quick clamping tube 8. The inner clamping tube 9 can extend into the quick clamping tube 8 in a directional manner. A tension spring 24 is installed on the inner side of the extension frame 11. The other end of the tension spring 24 is connected to the outer wall of the quick clamping tube 8. A conveying assembly 25 is installed on the side of the frame 1.

[0026] More specifically, initially, the drive motor 18 drives the guide roller 3 to rotate via the transmission chain assembly 19. The battery panel moves smoothly under the guidance of the bottom roller 2, guide roller 3, and side roller 4. At the same time, the transmission chain drives the eccentric plate 20 to rotate, and the application assembly 6 reciprocates and slides on the lifting frame 5 via the push-pull rod 21. The paint flows from the paint box 7 through the connecting channel of the inner clamp tube 9 and the quick clamp tube 8 to the application assembly 6. The guide rod 22 at the bottom of the paint box 7 is inserted into the guide sleeve 23 at the top of the application assembly 6 to ensure accurate paint delivery. When the battery panel passes through the application assembly 6, the application assembly 6 applies the paint evenly to the battery panel. After the application is completed, the battery panel continues to be transported to the next process by the conveying assembly 25 on the side of the frame 1. When the paint box 7 needs to be replaced, the operator moves the longitudinal sleeve 12, causing the push frame 13 on the longitudinal sleeve 12 to push the extension frame 11 out of the locking groove 10 of the inner clamp tube 9. At this time, the quick clamp tube 8 and the inner clamp tube 9 can be easily separated, realizing the quick replacement of the paint box 7.

[0027] In summary, during the use or operation of the overall equipment: when the stable guiding mechanism is required, the stable guiding mechanism provides stable guiding support for the movement of the battery panel through the combined action of the bottom roller 2, guide roller 3, and side roller 4. The drive motor 18 drives the guide roller 3 to rotate through the transmission chain assembly 19, so that the battery panel moves smoothly along the channel formed by the bottom roller 2 and the guide roller 3. At the same time, the eccentric plate 20 at the output end of the transmission chain is connected to the coating assembly 6 through the push-pull rod 21, so that the coating assembly 6 slides in a direction on the lifting frame 5 to realize the reciprocating coating action of the battery panel.

[0028] When the coating box clamping mechanism is in operation, the coating box clamping mechanism realizes the quick connection and disassembly of the coating box 7 and the coating assembly 6 through the cooperation of the quick clamping tube 8 and the inner clamping tube 9. The inner clamping tube 9 is connected to the top of the coating assembly 6, and a locking groove 10 is provided on its side wall. The quick clamping tube 8 is connected to the bottom of the coating box 7. When the coating box 7 needs to be installed, the inner clamping tube 9 is inserted into the quick clamping tube 8. The extension bracket 11 on the side wall of the quick clamping tube 8 is automatically embedded into the locking groove 10 of the inner clamping tube 9 under the action of the tension spring 24, locking the two together.

[0029] When the locking auxiliary mechanism is in operation, the locking auxiliary mechanism controls the longitudinal movement of the longitudinal sleeve 12 on the outer wall of the quick-lock tube 8 through the cooperation of the longitudinal moving block 14 and the bidirectional positioning spring 15. The pusher 13 installed on the longitudinal sleeve 12 can push the extension frame 11 to embed or disengage it from the locking groove 10 of the inner locking tube 9. When the longitudinal sleeve 12 moves, the bidirectional positioning spring 15 on the longitudinal moving block 14 will extend into the positioning groove 17 of the longitudinal moving groove 16 on the outer wall of the quick-lock tube 8 step by step, so that the longitudinal sleeve 12 can move stably in segments and provide precise locking control.

[0030] Initially, the drive motor 18 drives the guide roller 3 to rotate via the transmission chain assembly 19. The battery panel moves smoothly under the guidance of the bottom roller 2, guide roller 3, and side roller 4. At the same time, the transmission chain drives the eccentric plate 20 to rotate, and the application assembly 6 reciprocates and slides on the lifting frame 5 via the push-pull rod 21. The paint flows from the paint box 7 through the connecting channel of the inner clamp tube 9 and the quick clamp tube 8 to the application assembly 6. The guide rod 22 at the bottom of the paint box 7 is inserted into the guide sleeve 23 at the top of the application assembly 6 to ensure accurate paint delivery. When the battery panel passes through the application assembly 6, the application assembly 6 applies the paint evenly to the battery panel. After the application is completed, the battery panel continues to be transported to the next process by the conveying assembly 25 on the side of the frame 1. When the paint box 7 needs to be replaced, the operator moves the longitudinal sleeve 12, causing the push frame 13 on the longitudinal sleeve 12 to push the extension frame 11 out of the locking groove 10 of the inner clamp tube 9. At this time, the quick clamp tube 8 and the inner clamp tube 9 can be easily separated, realizing the quick replacement of the paint box 7.
