Technical Field

[0001] This utility model relates to the field of lithium-ion battery clamping technology, specifically to a clamping fixture for assembling lithium-ion batteries. Background Technology

[0002] Lithium-ion battery assembly fixtures are specialized tools used to fix, position, or press battery components together during battery production. They are typically made of metal or high-strength plastic. Their core function is to ensure precise alignment and stable stress on key components such as cells, electrodes, and separators during assembly, thereby improving battery consistency, safety, and production efficiency. Common types include electrode stacking fixtures, cell winding fixtures, and welding positioning fixtures. These fixtures must possess properties such as corrosion resistance, high-temperature resistance, and anti-static properties to meet the specific requirements of the lithium battery production environment.

[0003] Existing lithium-ion battery assembly fixtures do not have the function of adjusting the battery gap. During the lithium battery design process, the gap needs to be adjusted frequently, which requires different fixtures, leading to increased usage costs. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a fixture for assembling lithium-ion batteries, comprising:

[0025] Clamping base 1;

[0026] Adjustable positioning mechanism 2 is disposed on the top of clamping base 1. Adjustable positioning mechanism 2 is used for adjustable positioning of battery.

[0027] The clamping and positioning mechanism 3 is located on the top of the clamping base 1. The clamping and positioning mechanism 3 is used to cooperate with the adjustable positioning mechanism 2 to clamp and position the battery.

[0028] The adjustable positioning mechanism 2 includes a sliding adjustment component and a locking component. The sliding adjustment component includes a strip base 21, which is fixedly installed on the top of the clamping base 1. The top of the strip base 21 is coated with scale lines 22. A groove 23 is opened inside the strip base 21. A slider 24 is slidably connected to the inner wall of the groove 23. An indicator arrow 241 is fixedly connected to the top of the slider 24. A connecting arm 25 is fixedly installed on the outer wall of the slider 24. During the adjustment process, the user can slide the slider 24 inside the groove 23, thereby adjusting the position of the fitting clamp 26 left and right. As a result, the user can design various battery assembly gaps to meet production needs and reduce usage costs. With the indication of the indicator arrow 241 and the scale lines 22, the accuracy of the adjustment can be improved.

[0029] As one implementation method in this embodiment, such as Figure 2As shown, a fitting clamp 26 is fixedly installed at the end of the connecting arm 25 away from the sliding member 24. A round hole 261 is opened at the bottom of the fitting clamp 26, and a clamping groove 262 is opened on the side of the fitting clamp 26 away from the connecting arm 25. The design of the round hole 261 makes the fitting clamp 26 completely disconnected from the electrode at the bottom of the battery, increasing the safety of the electrode. The design of the clamping groove 262 facilitates the subsequent clamping of the battery inside the fitting clamp 26.

[0030] As one implementation method in this embodiment, such as Figure 3 As shown, the locking assembly includes a slider 243. A through hole 242 is provided on the side of the slider 24 away from the connecting arm 25. The slider 243 is slidably connected to the inner wall of the through hole 242. A connecting plate 244 is fixedly connected to the end of the slider 243. The locking assembly also includes a locking bolt 245, which is threadedly connected to the outer wall of the slider 24. The threaded end of the locking bolt 245 extends into the inner cavity of the slider 24 and is rotatably connected to the outer wall of the connecting plate 244. In the initial state, the end of the slider 243 abuts against the inner wall of the slide groove 23, locking the position of the slider 24 inside the scale line 22. If the position of the slider 24 needs to be adjusted, loosen and rotate the locking bolt 245 to make the slider 243 slide on the inner wall of the through hole 242 and move away from the slide groove 23, thus releasing the lock on the position of the slider 24. After the slider 24 is adjusted, tighten the locking bolt 245 to drive the slider 243 to reset and abut against the inner wall of the slide groove 23, thereby fixing the position of the slider 24.

[0031] As one implementation method in this embodiment, such as Figure 4 As shown, the clamping and positioning mechanism 3 includes a support leg 31, which is fixedly installed on the top of the clamping base 1. A support cross seat 32 is fixedly installed on the top of the support leg 31. A cylinder 33 is fixedly installed on the outer wall of the support cross seat 32. The telescopic end of the cylinder 33 extends to the other side of the support cross seat 32 and is fixedly connected to a connector 35. After the battery is inserted into the inner cavity of the fitting clamp 26 in sequence, the cylinder 33 is controlled to extend, which can drive the connector 35 to move towards the battery and pass through the clamping groove 262 to contact the outer wall of the battery, thus realizing the function of clamping the battery. The cylinder 33 is controlled to reset, which can release the clamping of the battery.

[0032] As one implementation method in this embodiment, such as Figure 4 As shown, a sliding rod 34 is fixedly installed on the outer wall of the connector 35. The sliding rod 34 is slidably connected to the inner wall of the support cross seat 32. When the cylinder 33 extends and retracts to move the connector 35, the sliding rod 34 will slide synchronously on the inner wall of the support cross seat 32, increasing the overall stability of the connector 35.

[0033] As one implementation method in this embodiment, such as Figure 4As shown, a connecting rod 36 is fixedly connected to the side of the connector 35 away from the sliding rod 34. An arc-shaped rubber strip 37 is fixedly connected to the outer wall of the connecting rod 36. Through the design of the arc-shaped rubber strip 37, the contact surface between the connecting rod 36 and the battery is a flexible structure, which reduces the damage to the battery caused by clamping and ensures the safety of the battery.

[0034] Working principle: Before clamping, the spacing of the engaging clamp 26 is designed first. Loosening the locking bolt 245 causes the slider 243 to slide on the inner wall of the through hole 242 and move away from the slide groove 23. The engaging clamp 26 can then be adjusted by sliding. During the adjustment, refer to the indication arrow 241 and the scale line 22. After adjustment, tighten the locking bolt 245 to drive the slider 243 to reset and abut against the inner wall of the slide groove 23, thus fixing the position of the engaging clamp 26. Then, the battery is inserted into the inner cavity of the engaging clamp 26 in sequence. The control cylinder 33 extends, which can drive the connector 35 to move towards the battery and pass through the clamping groove 262 to contact the outer wall of the battery, thus realizing the function of clamping the battery.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
