[0002] Global warming and the development of technology have promoted the rise of new energy. Batteries are widely used in all walks of life, and the research on batteries is more comprehensive. The basic research of domestic enterprises on lithium-ion batteries mostly focuses on the testing of single battery cells. Among them, cylindrical batteries and soft-pack batteries are the most commonly used in research. Soft-pack batteries are widely used in fields such as 3C consumer electronics, new energy vehicles, and power batteries due to their good safety function, light weight, large battery capacity, and good cycling function.

[0003] In the experimental stage of soft-pack batteries, the research from battery baking, liquid injection to battery performance testing is mostly manual operation. In order to more fully dry the residual moisture in the battery cell, it is generally selected to open the air bag mouth as much as possible so that the moisture can volatilize quickly. Similarly, when injecting liquid into a dry battery cell, we also expect to open the air bag mouth to facilitate the addition of electrolyte. However, using tweezers to open the air bag is likely to scratch the aluminum-plastic film, and the size of the air bag mouth opened by the tweezers is very limited, and the problem cannot be well solved.

[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0024] Embodiment 1

[0025] Please refer to Figure 1 and Figure 2 As shown, an auxiliary tool for manufacturing a soft-pack battery includes a main forceps frame 1. The main forceps frame 1 is of a V-shaped structure and includes two connecting rods 5. The connecting rods 5 have a first end and a second end. Among them, the two first ends are hinged by a pin shaft to realize the relative rotation between the two connecting rods 5. An elastic member 6 is arranged between the two connecting rods 5, and the elastic member 6 is close to the first end. The elastic force of the elastic member 6 makes the two second ends move away from each other, and the main forceps frame 1 is in an initial state without external force; among them, the type of the elastic member 6 is, for example: a spring.

[0026] The pneumatic device is arranged inside the connecting rod 5;

[0027] Specifically, a receiving groove is formed inside the connecting rod 5, and the receiving groove communicates with the second end. The pneumatic device includes an internal air pipe 2. The internal air pipe 2 includes an air delivery pipe 7 and an air storage member 8 that are connected and communicate with each other. Among them, the end of the air delivery pipe 7 away from the air storage member 8 is close to the second end;

[0028] Furthermore, the air storage member 8 includes a first air storage portion 10 and a second air storage portion 11 that are connected and communicate with each other. The first air storage portion 10 is close to the air delivery pipe 7;

[0029] It should be noted that in the natural state, the internal and external pressures of the built-in trachea 2 are the same. At this time, both the first air storage part 10 and the second air storage part 11 are spherical, and a concave part is formed between the first air storage part 10 and the second air storage part 11. After the air storage member 8 is pressed, the air inside the first air storage part 10 and the second air storage part 11 is discharged outward through the air delivery pipe 7;

[0030] Furthermore, the pneumatic device further includes a pneumatic switch 4;

[0031] Specifically, on the side walls of the two connecting rods 5 away from each other, moving grooves are provided at positions corresponding to the air storage member 8. The moving grooves communicate with the accommodating grooves. The pneumatic switch 4 is slidably arranged in the moving grooves. The pneumatic switch 4 includes an operating end and a pressing trigger end. The operating end is located outside the connecting rod 5, and the pressing trigger end penetrates through the moving groove and extends into the accommodating groove for contacting the air storage member 8;

[0032] Furthermore, the pneumatic switch 4 has three - gear adjustment. Among them, the first gear corresponds to the concave part between the first air storage part 10 and the second air storage part 11, the second gear corresponds to the first air storage part 10, and the third gear corresponds to the second air storage part 11;

[0033] When the pneumatic switch 4 is in the first gear, the pressing trigger end is located in the concave part. At this time, the pressing trigger end does not contact the first air storage part 10 and the second air storage part 11, and the built - in trachea 2 is in the natural state and does not perform the actions of inhaling and exhaling;

[0034] When the pneumatic switch 4 is in the second gear, the pressing trigger end is located in the first air storage part 10. During the process of adjusting the pneumatic switch 4 from the first gear to the second gear, the pressing trigger end moves from the concave part to the first air storage part 10, continuously pressing the first air storage part 10, thereby discharging the air inside the first air storage part 10;

[0035] When the pneumatic switch 4 is in the third gear, the pressing trigger end is located in the second air storage part 11. During the process of adjusting the pneumatic switch 4 from the first gear to the third gear, the pressing trigger end moves from the concave part to the second air storage part 11, continuously pressing the second air storage part 11, thereby discharging the air inside the second air storage part 11 and the first air storage part 10;

[0036] The pneumatic device further includes a connecting piece 9 and a suction cup assembly;

[0037] Specifically, the connecting piece 9 is arranged at the second end of the connecting rod 5. Its interior is hollow and is communicated with the end of the air delivery pipe 7 away from the air storage member 8, and the airtightness is ensured;

[0038] Furthermore, the suction cup assembly includes a suction cup 3 and a connecting portion, the suction cup 3 and the connecting portion are connected, and the connecting portion and the connecting member 9 are connected and connected; the suction cup 3 is made of a silicone or rubber material with good airtightness and softness, which can better fit the aluminum-plastic film of the soft-pack battery so as to prevent air leakage and increase the contact area;

[0039] Optionally, the connector 9 is a threaded connector, which is threadedly connected to the connecting portion and can ensure sealing performance;

[0040] It should be noted that the threaded connector can adapt to suction cups 3 of different specifications and to the adsorption of objects of different sizes, thereby improving applicability and facilitating replacement of the suction cup 3.

[0041] Thus, the built-in air pipe 2 is connected to the suction cup 3 , and in the process of adjusting the gear position of the pneumatic switch 4 by moving the operating end, the air can enter and be discharged from the air storage part 8 through the suction cup 3 and the air pipe 7 .

[0042] Working principle: when the device is not used, under the action of the elastic force of the elastic member 6, the tweezers main frame 1 is in the initial state, the pneumatic switch 4 is in the first gear, and the second ends of the two connecting rods 5 are far apart. When in use, the aluminum-plastic film of the soft-pack battery to be adsorbed is placed between the two suction cups 3, and the pneumatic switch 4 is moved and adjusted from the first gear to the second gear, and the extrusion trigger end is moved from the recessed part to the first air storage part 10. During this process, the extrusion trigger end continuously squeezes the first air storage part 10, so that the air in the first air storage part 10 is discharged through the air delivery pipe 7 and the suction cup 3, and then the tweezers main frame 1 is operated to make the two suction cups 3 approach each other and contact the aluminum-plastic film of the soft-pack battery respectively, and then the pneumatic switch 4 is adjusted from the second gear to the first gear, and the extrusion trigger end is moved from the first air storage part 10 to the recessed part. During this process, the extrusion trigger end gradually moves away from the first air storage part 10 and no longer squeezes the first air storage part 10. The first air storage part 10 can be restored to its original state. Since the suction cup 3 contacts the aluminum-plastic film of the soft-pack battery, a negative pressure suction force is generated at the suction cup 3 during the process of the first air storage part 10 being in its original state, and the aluminum-plastic film of the soft-pack battery can be adsorbed. Then, the tweezers main frame 1 is released. Under the elastic force of the elastic member 6, the tweezers main frame 1 can be restored to its initial state, so that the two suction cups 3 can drive the aluminum-plastic film of the soft-pack battery adsorbed thereon to be away from each other, so that the opening between the two layers of aluminum-plastic film is opened. Finally, the pneumatic switch 4 is adjusted from the first gear to the third gear, and the extrusion trigger end is moved from the recessed part to the second air storage part 11. During this process, the extrusion trigger end continuously squeezes the second air storage part 11, so that the air in the second air storage part 11 is discharged to the first air storage part 10, and then the air in the first air storage part 10 and the second air storage part 11 are discharged through the air delivery pipe 7 and the suction cup 3. At this point, the suction cup 3 can release the adsorption of the aluminum-plastic film of the soft-pack battery, and then the soft-pack battery can be baked and injected.

[0043] By adsorbing and releasing the aluminum-plastic film of the soft-pack battery through air pressure changes, and the suction cup 3 contacting the aluminum-plastic film of the soft-pack battery, it is possible to avoid scratching the aluminum-plastic film. The device has a simple design, low cost, and is easy to operate. It can avoid damaging the aluminum-plastic film of the soft-pack battery and greatly improve work efficiency.
