Description

Technical Field

[0001] This utility model relates to the field of battery terminal processing technology, specifically a tooling for passivating battery terminals. Background Technology

[0002] In battery production, electrode passivation is a crucial step in ensuring battery performance and lifespan. Traditional processing fixtures typically involve directly immersing multiple battery electrodes in a solution tank within a basket, which can easily lead to electrode collisions and surface damage, affecting passivation effectiveness and battery electrode quality. Therefore, there is an urgent need for a new passivation processing fixture that can stably hold battery electrodes, prevent surface damage, and support batch processing to meet the demands of modern battery production for efficient and high-quality processes.

[0003] As disclosed in patent announcement CN221419034U, a passivation code disk includes a code disk body. The code disk body includes at least one placement mechanism, which includes at least three first pillars forming a placement position. Multiple first liquid channels are provided on the placement position, and a support member is formed between adjacent first liquid channels. A copper riveted electrode is placed within the placement position and limited by the first pillars, which are mounted on the support member. Two code disk bodies are stacked to form a placement cavity between the placement position and the bottom of the upper code disk body. The copper riveted electrode is placed within the placement cavity. The copper riveted electrode can be placed within the placement cavity and can move within it. Due to the first liquid channels, passivation liquid or cleaning liquid can flow over the surface of the copper riveted electrode, increasing the passivation or cleaning effect.

[0004] While the aforementioned solution improves the passivation effect of the battery terminals through the arrangement of multiple placement chambers and multiple liquid channels, its complex structure means that the terminals still have significant coverage areas on both sides during use, affecting the sufficient contact between the outer surface of the terminals and the cleaning or passivation solution. Furthermore, the lack of terminal fixing measures makes the terminals prone to displacement during passivation or cleaning. Therefore, we propose a battery terminal passivation treatment fixture that solves the problems of insufficient terminal passivation and terminal fixing in the current solution, improving the passivation effect and thus increasing the product yield. Utility Model Content

[0005] The purpose of this utility model is to provide a battery terminal passivation treatment fixture to solve the problems of insufficient terminal passivation treatment and terminal fixation in the existing solutions mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A passivation treatment fixture for battery terminals includes a rectangular frame, the interior of which is divided into three clamping frames at equal intervals. Sliding grooves are provided on both sides of the clamping frames, and clamping plates are slidably installed inside the sliding grooves. Each pair of clamping plates forms a group, and the spacing between each group of clamping plates is equal.

[0008] As a further embodiment of this utility model: an adjusting rod is provided at the lower end of the clamping plate, the adjusting rod is composed of multiple bidirectional threaded segments, a separator ring is fixedly provided in the middle of the bidirectional threaded segments, and limit rings are fixedly provided at both ends of the bidirectional threaded segments.

[0009] As a further embodiment of this utility model: each set of clamping plates is symmetrically arranged on both sides of the partition ring and threadedly connected to the bidirectional threaded section. A clamping protrusion is fixedly provided on one side of each clamping plate. The end of the clamping protrusion is made of silicone rubber material. The clamping protrusion is located on the side of each set of clamping plates that is close to each other.

[0010] As a further improvement of this utility model: multiple battery electrode placement slots are symmetrically provided on both sides of the clamping frame. The battery electrode placement slots have a Y-shaped structure with rounded corners at the upper end. The battery electrode placement slots are arranged in groups of two, and each group is symmetrically distributed about the longitudinal axis of the short side of the clamping frame. The spacing between each group of battery electrode placement slots is equal. A battery terminal is inserted into each group of battery electrode placement slots. The line connecting the centers of the bottom surfaces of each group of battery electrode placement slots is on the same plane as the perpendicular bisector of the bidirectional threaded section.

[0011] As a further embodiment of this utility model: the two ends of the adjusting rod are rotatably connected to the inner wall of the rectangular frame through bearings, one end of the adjusting rod passes through the rectangular frame and is fixedly provided with a rotating handle, the rotating handle is rotatably installed on the outside of the rectangular frame, a lifting rod is fixedly provided on the top surface of the rectangular frame, and multiple support feet are evenly distributed on the bottom surface of the clamping frame.

[0012] Compared with the prior art, this utility model provides a tooling for passivating battery terminals, which has the following advantages:

[0013] 1. This battery terminal passivation treatment fixture, through multiple clamping frames set inside a rectangular frame, and multiple sets of clamping plates and battery terminal placement slots set inside the clamping frames, when the battery terminal is passivated or cleaned, first place the battery terminal in the battery terminal placement slot, and then rotate the handle clockwise to drive the adjusting rod to rotate, thereby driving the multiple sets of clamping plates connected by the outer threads of the bidirectional thread section to clamp the battery terminal simultaneously, so that the battery terminal is fixed in the battery terminal placement slot. This clamping and fixing method is simple and convenient to operate, and multiple battery terminals can be clamped at one time, avoiding the problem of battery terminals falling out of the slot during passivation or cleaning. At the same time, it also facilitates the staff to dry the passivated battery terminals 10.

[0014] 2. The battery terminal passivation treatment fixture, by providing a clamping protrusion on one side of the clamping plate and a silicone rubber contact at the end of the clamping protrusion, enables the clamping plate to ensure the stability and surface quality of the battery terminal without affecting the battery terminal's full contact with the passivation treatment liquid.

[0015] 3. This battery terminal passivation treatment fixture, through multiple sets of battery terminal placement slots with consistent spacing, allows the battery terminals to maintain spacing during the processing, avoiding the mutual wear problem between terminals caused by traditional stacking cleaning methods, thereby improving the processing quality of the battery terminals.

[0024] Example: A tooling for passivating battery terminals, such as... Figures 1-3 As shown, the device includes a rectangular frame 1, which is divided into three clamping frames 2 at equal intervals. Sliding grooves 3 are provided on both sides of each clamping frame 2, and clamping plates 4 are slidably installed inside the sliding grooves 3. Each pair of clamping plates 4 forms a group, and the spacing between each group of clamping plates 4 is equal. A clamping protrusion 8 is fixedly provided on one side of each clamping plate 4. The end of the clamping protrusion 8 is made of silicone rubber. The clamping protrusion 8 is located on the side closest to each group of clamping plates 4. Multiple battery electrode placement slots 9 are symmetrically provided on both sides of the clamping frame 2. The battery electrode placement slots 9 have a Y-shaped structure with rounded corners at their upper ends. The battery electrode placement slots 9 are arranged in groups of two, and each group is symmetrically distributed about the short longitudinal axis of the clamping frame 2. The spacing between each group of battery electrode placement slots 9 is equal. A battery electrode post 10 is inserted into each group of battery electrode placement slots. The line connecting the centers of the bottom surfaces of each group of battery electrode placement slots 9 and the perpendicular bisector of the bidirectional thread section are located on the same plane.

[0025] In this embodiment, the arrangement of multiple battery terminal placement slots 9 enables the processing of multiple battery terminals 10 in a single operation. The battery terminal placement slots 9 have a Y-shaped structure with rounded corners at the upper ends, facilitating quick and accurate positioning by operators and improving the installation speed of the battery terminals 10. The clamping protrusions 8 fixedly disposed on one side of the clamping plate 4 effectively reduce the surface coverage of the battery terminals 10, ensuring the passivation effect of the battery terminals 10, while maintaining the clamping effect without compromising its overall performance.

[0026] like Figure 1 and Figure 4As shown, the device includes a rectangular frame 1, which is divided into three clamping frames 2 at equal intervals. Sliding grooves 3 are provided on both sides of the clamping frames 2, and clamping plates 4 are slidably installed inside the sliding grooves 3. An adjusting rod 5 is passed through the lower end of the clamping plate 4. The adjusting rod 5 is composed of multiple bidirectional threaded segments. A partition ring 6 is fixedly provided in the middle of the bidirectional threaded segments, and limit rings 7 are fixedly provided at both ends of the bidirectional threaded segments. Each set of clamping plates 4 is symmetrically arranged on both sides of the partition ring 6 and threadedly connected to the bidirectional threaded segments. The two ends of the adjusting rod 5 are rotatably connected to the inner wall of the rectangular frame 1 through bearings. One end of the adjusting rod 5 passes through the rectangular frame 1 and is fixedly provided with a rotating handle 11. The rotating handle 11 is rotatably installed on the outside of the rectangular frame 1. A lifting rod 12 is fixedly provided on the top surface of the rectangular frame 1, and multiple support feet 13 are distributed at equal intervals on the bottom surface of the clamping frames 2.

[0027] In this embodiment, by using multiple bidirectional threaded sections on the adjusting rod 5, when it is necessary to clamp the battery terminal 10, rotating the handle 11 clockwise will move the clamping plate 4 toward the surface of the battery terminal 10, thereby achieving the clamping effect. This clamping method can quickly and simultaneously clamp and fix multiple battery terminals 10, resulting in high efficiency. After the battery terminal passivation treatment is completed, rotating the handle 11 counterclockwise will release the clamping plate 4, making it easy to remove the battery terminal 10.

[0028] In this embodiment, a battery terminal passivation fixture is used by first inserting the battery terminal 10 into the Y-shaped battery terminal placement grooves 9 on both sides of the clamping frame 2. Then, by rotating the handle 11 clockwise, the adjusting rod 5 is rotated, which in turn moves multiple sets of clamping plates 4 connected by the outer threads of the bidirectional threaded section. Since every two clamping plates 4 are symmetrically arranged on both sides of the separating ring 6, and the two ends of the clamping plates 4 are slidably installed inside the sliding groove 3, the movement stability of the clamping plates 4 is effectively ensured, so that each set of clamping plates 4 can achieve the clamping and fixing effect on the battery terminal 10. During the clamping process, the clamping protrusion 8 is provided on one side of the clamping plate 4, and the end of the clamping protrusion 8 is provided with a silicone rubber contact, so that the clamping plate 4 can ensure the stability and surface quality of the battery terminal 10 without affecting the full contact of the battery terminal 10 with the passivation treatment liquid. Finally, the rectangular frame 1 holding multiple battery terminals 10 is placed into the passivation treatment tank by the lifting rod 12.
