Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to an auxiliary device for stacking solid-state battery electrodes. Background Technology

[0002] Unlike the commonly used lithium-ion and lithium-ion polymer batteries, solid-state batteries are batteries that use solid electrodes and solid electrolytes. Solid-state battery electrodes play a crucial role in solid-state batteries, with their main functions including storing and providing electrical energy, conducting current, and catalyzing chemical reactions. Battery cells are generally composed of positive and negative electrodes stacked alternately. Existing stacking devices require manual operation when stacking battery electrodes. Manual stacking cannot level the alternately stacked battery electrodes as needed, and manual alignment relies on visual inspection, which cannot guarantee dimensional accuracy. This results in poor alignment, making the electrodes prone to misalignment and short circuits during the stacking process. This seriously affects the performance and quality uniformity of the battery product and requires re-stacking, thereby reducing the effectiveness of use. Utility Model Content

[0018] This utility model has the following beneficial effects:

[0019] The system utilizes a drive L-shaped plate, drive motor, drive support plate, and drive shaft. The drive motor rotates the drive support plate and drive shaft, which then slides inside the corresponding assembly ring plate. This causes the assembly support plate on the assembly ring plate to move along the direction of the receiving plate. The assembly push plate on the assembly support plate also moves, aligning the two assembly push plates against the sides of the stacked electrode sheets. A movable sleeve block, movable J-shaped plate, movable motor, movable rod, and movable wheel work together. The movable motor drives the movable wheel to rotate. The movable wheel contacts the inner wall of the movable groove, generating friction, causing the two movable wheels to move closer together inside the groove. The movable sleeve block on the movable motor then moves closer together along the direction of the movable support. The movable J-shaped plate is then installed on the movable sleeve block, pressing against the front and rear edges of the stacked electrode sheets, maintaining their flatness and alignment. This eliminates the need for manual leveling and alignment, improving performance. Attached Figure Description

[0027] Reference Figure 1-4This utility model provides a solid-state battery electrode stacking auxiliary device, including a processing table 1. Two symmetrical receiving plates 2 are fixedly connected to the top of the processing table 1. A receiving bracket 3 is fixedly connected between the two receiving plates 2. A cylinder 4 is fixedly connected to the top of the receiving bracket 3. The piston end of the cylinder 4 passes through the receiving bracket 3 and is fixedly connected to a pressing plate 5. Two assembly support plates 6 are provided through the side walls of the receiving plates 2. An assembly loop plate 7 is fixedly connected between one end of the two assembly support plates 6, and an assembly push plate 8 is fixedly connected between the other ends of the two assembly support plates 6. An adjustment assembly loop plate 7 is connected to the side walls of the receiving plates 2 for adjusting the assembly loop plate 7. The movable drive assembly is used to adjust the movement of the assembly ring plate 7. The drive assembly includes a drive L-shaped plate 9 fixedly connected to the side wall of the receiving plate 2. A drive motor 10 is fixedly connected to the top of the drive L-shaped plate 9. A drive rod is fixedly connected to the output end of the drive motor 10. The end of the drive rod passes through the drive L-shaped plate 9 and is fixedly connected to a drive support plate 11. A drive shaft 12 is rotatably connected to the bottom of the drive support plate 11. The drive shaft 12 is slidably connected to the interior of its corresponding assembly ring plate 7. The drive motor 10 drives the drive rod and the drive support plate 11 to rotate.

[0028] The processing table 1 has multiple electrode plates 19 on its top. Two positive electrode tabs 20 are fixedly connected to the surface of the electrode plates 19, and two negative electrode tabs 21 are fixedly connected to the back of the electrode plates 19. A movable bracket 13 is fixedly connected to the side wall of the assembly push plate 8. The side wall of the movable bracket 13 has a movable groove. Two symmetrical movable components are movably sleeved on the outer side wall of the movable bracket 13. The movable components include a movable sleeve block 14 that is movably sleeved on the outer side wall of the movable bracket 13. A movable J-shaped plate 15 is fixedly connected to the top of the movable sleeve block 14. A movable motor 16 is fixedly connected to the side wall of the movable sleeve block 14. A movable rod 17 is fixedly connected to the output end of the movable motor 16. The end of the movable rod 17 passes through the movable sleeve block 14 and extends into the movable groove. A movable wheel 18 is fixedly connected to the end of the movable rod 17. The movable motor 16 drives the movable rod 17 to rotate.

[0029] Working principle: In use, first place the stacked electrode sheets 19 on the top of the processing table 1, then align the positive electrode tabs 20 and negative electrode tabs 21 on each electrode sheet 19, and then start the drive motor 10. The drive motor 10 drives the drive rod and drive support plate 11 to rotate. Then the drive support plate 11 also drives the drive shaft 12 to slide inside its corresponding assembly ring plate 7, so that the assembly support plate 6 on the assembly ring plate 7 moves along the direction on the receiving plate 2. Then the assembly push plate 8 on the assembly support plate 6 also moves, so that the two assembly push plates 8 are aligned with the two sides of the stacked electrode sheets 19 after being pressed together, ensuring the alignment effect.

[0030] Then, the two movable motors 16 on the movable support 13 are started, which drive the movable rod 17 and the movable wheel 18 to rotate. Because the movable wheel 18 contacts the inner wall of the movable groove and generates friction, the two movable wheels 18 move and approach each other inside the movable groove. Then, the movable sleeve block 14 on the movable motor 16 approaches each other along the direction on the movable support 13. Because the movable sleeve block 14 is equipped with a movable J-shaped plate 15, the movable J-shaped plate 15 presses against the front and rear edges of the stacked electrode sheets 19 to keep the electrode sheets flat and aligned. Finally, the cylinder 4 is started, which pushes the pressing plate 5 downward to press and flatten the stacked electrode sheets 19, ensuring further alignment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
