[0002] In the lithium-ion battery industry, fully automatic liquid injection machines are welcomed by many companies due to their high efficiency, stable working environment, and easy operability. At the same time, the amount of liquid injected by the fully automatic liquid injection machine is a very important indicator. Too much liquid will lead to safety risks for pouch lithium batteries, while too little liquid will cause the capacity, voltage, and other properties of the pouch lithium batteries to fail to meet the requirements, resulting in product scrap.

[0003] Furthermore, most existing battery filling machines lack automatic fixing devices for pouch lithium batteries, making manual fixing prone to worker injuries and resulting in low production efficiency, thus failing to meet the demands of large-scale production. Therefore, we propose a pouch lithium battery linear filling machine. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 6 This utility model provides a technical solution: a soft-pack linear lithium battery filling machine, including a processing table 2, a conveyor belt 11 rotatably connected to the top of the processing table 2, and mounting seats 1 symmetrically connected to the top of the processing table 2. The conveyor belt 11 is rotatably connected between the mounting seats 1, and one end of the conveyor belt 11 is driven by a motor 9. Multiple card seats 10 are equidistantly connected to the outer surface of the conveyor belt 11, and a placement seat 27 is clamped onto the card seat 10. The bottom of the placement seat 27 has a slot 20, and the bottom of the placement seat 27 is slidably connected to the card seat 10 through the slot 20. The cooperation between the slot 20 and the card seat 10 makes it convenient for the user to stably place the placement seat 27 on the top of the conveyor belt 11, and also makes it convenient to remove the placement seat 27 from the top of the conveyor belt 11. The structure is simple and highly practical.

[0024] like Figure 4 , 5 As shown in Figure 6, a first placement groove 23 is provided on the top of the placement base 27. One end of the first placement groove 23 extends through the placement base 27, and a second placement groove 25 is symmetrically provided on the top of the placement base 27 along the first placement groove 23. An opening 24 is provided on the adjacent side of each of the second placement grooves 25. A clamping plate 22 is connected to the upper end of each of the second placement grooves 25 through a rotating shaft 21. The middle part of the clamping plate 22 bends and extends into the first placement groove 23. Multiple return springs 5 ​​are connected between the lower end of the clamping plate 22 and the inner bottom surface of the second placement groove 25 to hold the battery pack ( Figure 6(As indicated by the middle arrow A) is placed between two clamping plates 22. Since the middle part of the clamping plate 22 is bent and extends into the first placement groove 23 through the opening 24, it can clamp both sides of the battery soft pack, which improves the stability of placing the battery soft pack, effectively avoids the battery soft pack from shifting position, and thus improves the quality of liquid injection.

[0025] Meanwhile, in order to achieve stable extension and retraction of the reset spring 5, a second connecting rod 26 is tightly fastened to the lower end of the second placement groove 25, and a first connecting rod 12 is connected to the bottom of the clamping plate 22. Both ends of the reset spring 5 are connected to sleeves 6, and the two sleeves 6 are slidably connected to the second connecting rod 26 and the first connecting rod 12 respectively.

[0026] In summary, this soft-pack linear lithium battery injection machine has an injection mechanism connected to the processing table 2 above the conveyor belt 11 during use. The injection mechanism includes a bracket 16 fastened to the top of the processing table 2, one end of which extends above the conveyor belt 11, and a connecting seat 3 is connected below the bracket 16. The connecting seat 3 is connected to the bracket 16 via an electric push rod 18, and multiple guide rods 17 penetrating the bracket 16 are vertically connected to the top of the connecting seat 3, effectively improving the stability of the connecting seat 3's up-and-down sliding. Multiple injection pipes 4 are connected to the connecting seat 3; the injection pipes 4 are connected to the pump 13 via an infusion pipe 14, and the inlet end of the pump 13 is connected to the electrolyte tank 15.

[0027] like Figure 6 As shown, the battery packs that need to be injected are placed into the first placement groove 23 from one side of the placement seat 27. Under the action of the clamp 22 in the first placement groove 23, the stability of the battery pack placement can be effectively improved. A protective plate 8 is fixedly connected along the circumference on one side of the conveyor belt 11, which can limit the placement of the placement seat 27, thereby ensuring the stable placement of the battery packs. After multiple battery packs are placed, the battery packs are moved to the bottom of the injection tube 4 by the drive of the conveyor belt 11. The injection tube 4 can be moved to the top of the battery packs and the injection operation can be performed by adjusting the extension and retraction of the electric push rod 18.

[0028] After the liquid injection is completed, the battery pouch is transported to the other end of the conveyor belt 11 and unloaded. The staff can remove the battery pouch individually, or the placement seat 27 can be removed as a whole to unload the battery pouch in batches. During the unloading operation, in order to facilitate the staff to pull the placement seat 27, end plates 19 are symmetrically connected to the outer wall of the placement seat 27 near the opening of the first placement groove 23. This utility model also includes a control box 7, which is connected to a controller, and the motor 9, the liquid pump 13, and the electric push rod 18 are connected to the controller.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
