Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a lithium battery negative electrode polishing device. Background Technology

[0002] Lithium-ion batteries are widely used in mobile phones, digital cameras, laptops, and electric vehicles due to their advantages such as light weight, large capacity, and no memory effect. During lithium-ion battery production, the negative electrode is typically rectangular in shape and requires polishing. The purpose of polishing is to remove surface protrusions, pits, or oxide films, thereby improving conductivity and ensuring good contact between the battery terminals and the capacity testing probes.

[0003] In the prior art, a Chinese patent document with publication number CN216179262U and publication date of April 5, 2022 was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a lithium battery negative electrode positioning grinding device, including a worktable with a grinding device installed, positioning plates fixedly connected to both sides of the upper end of the worktable, a top cover plate fixedly connected to the upper end of the two positioning plates, a cylinder fixedly connected to the bottom end of the top cover plate, and an adjustment plate fixedly connected to the output end of the cylinder.

[0004] To address the positioning issue during lithium battery polishing, existing technologies utilize two baffles and two push plates to gather the negative electrode of the lithium battery towards the center of the processing plate, allowing the polishing device to better process the negative electrode. However, the gathering method of the push plates and baffles relies on structural linkage. For lithium battery negative electrodes that are too small or too large, there may be problems with unstable clamping or ineffective gathering, making it difficult to flexibly adapt to the polishing needs of various specifications of negative electrodes, thus limiting the processing capabilities. Utility Model Content

[0005] The purpose of this invention is to provide a lithium battery negative electrode polishing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A lithium battery negative electrode polishing device includes a polishing apparatus, the polishing apparatus including a polishing table, a guide plate fixedly installed on the front side of the polishing table, and a support bracket fixedly installed on the rear side of the polishing table.

[0008] The grinding table has movable grooves on both the front and rear edges, and a sliding rod is fixedly installed inside the movable groove. The sliding rod can limit the movement of the clamping plate.

[0009] A further improvement of this utility model is that: a limiting rod is fixedly installed at both the upper and lower ends of the bearing bracket, and an electric telescopic rod is fixedly installed on the inner side of the rear end of the bearing bracket. The limiting rod can limit the movement of the moving plate.

[0010] A further improvement of this utility model is that a motion plate is fixedly installed on the other end of the electric telescopic rod, and limit blocks are fixedly installed at both the upper and lower ends of the motion plate, with the limit blocks slidably sleeved on the outer surface of the limit rod.

[0011] A further improvement of this utility model is that a connecting sleeve is fixedly installed on the front side of the motion plate, and a push-pull rod is rotatably sleeved on the outer surface of the inner rod of the connecting sleeve.

[0012] A further improvement of this utility model is that a rotating shaft is rotatably connected to the other end of the push-pull rod, and a clamping plate is fixedly installed at the other end of the rotating shaft.

[0013] A further improvement of this utility model is that: sliders are fixedly installed on both sides of the bottom end of the clamping plate, the sliders are slidably sleeved on the outer surface of the slide rod, and rubber pads are fixedly installed on the inner side of the clamping plate. The rubber pads can enhance the clamping friction during clamping and also serve the purpose of protection.

[0014] A further improvement of this utility model is that: a connecting plate is fixedly sleeved on the outer surface of the inner rod of the connecting sleeve at the upper and lower ends, and a pusher plate is fixedly installed on the other end of the connecting plate.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a lithium battery negative electrode grinding device. By setting an electric telescopic rod to drive the moving plate to move, the push-pull rod pulls the clamping plate to slide along the slide bar. The angle change of the push-pull rod realizes the flexible adjustment of the clamping plate spacing, which can be adapted to lithium battery negative electrodes of different sizes, thereby improving the convenience.

[0017] 2. This utility model provides a lithium battery negative electrode grinding equipment. The automatic clamping and releasing action is completed by setting the telescopic movement of the electric telescopic rod to link the clamping plate. No manual operation is required, which reduces the labor input. The connecting plate on the connecting sleeve drives the pusher plate to move synchronously. After grinding, the negative electrode can be automatically pushed to the guide inclined plate for unloading. This forms a continuous automated process, shortens the processing cycle, and improves the overall production efficiency. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-5 As shown, this utility model provides a lithium battery negative electrode polishing device, including a polishing device 1. The polishing device 1 includes a polishing table 2. A guide plate 4 is fixedly installed on the front side of the polishing table 2, and a bearing bracket 3 is fixedly installed on the rear side of the polishing table 2. Moving grooves 21 are provided on both the front and rear edges of the polishing table 2. A sliding rod 22 is fixedly installed inside the moving groove 21. A connecting plate 311 is fixedly sleeved on the upper and lower ends of the inner rod of the connecting sleeve 35. A pusher plate 312 is fixedly installed on the other end of the connecting plate 311.

[0027] Furthermore, after grinding, the electric telescopic rod 32 drives the moving plate 33 to reset. At this time, the push-pull rod 36 pushes the clamping plate 38 to slide outward along the slide rod 22, releasing the clamping of the negative terminal of the lithium battery. At the same time, the connecting plate 311 on the connecting sleeve 35 moves with the connecting sleeve 35, driving the pusher plate 312 to move forward synchronously. The pusher plate 312 moves forward and pushes the ground lithium battery forward to achieve unloading.

[0028] Example 2

[0029] like Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a limiting rod 31 is fixedly installed at both the upper and lower ends of the inner side of the bearing bracket 3, an electric telescopic rod 32 is fixedly installed on the inner side of the rear end of the bearing bracket 3, a moving plate 33 is fixedly installed on the other end of the electric telescopic rod 32, a limiting block 34 is fixedly installed at both the upper and lower ends of the moving plate 33, the limiting block 34 is slidably sleeved on the outer surface of the limiting rod 31, a connecting sleeve 35 is fixedly installed on the front side of the moving plate 33, a push-pull rod 36 is rotatably sleeved on the outer surface of the inner rod of the connecting sleeve 35, a rotating shaft 37 is rotatably connected to the other end of the push-pull rod 36, a clamping plate 38 is fixedly installed at the other end of the rotating shaft 37, a slider 310 is fixedly installed on both sides of the bottom end of the clamping plate 38, the slider 310 is slidably sleeved on the outer surface of the slide rod 22, and a rubber pad 39 is fixedly installed on the inner side of the clamping plate 38.

[0030] Furthermore, the electric telescopic rod 32 starts to retract and pulls the moving plate 33 backward. Since the limiting blocks 34 at the upper and lower ends of the moving plate 33 are slidably sleeved on the limiting rod 31 inside the bearing bracket 3, the moving plate 33 will move smoothly along the axis of the limiting rod 31 to avoid deviation. During the movement of the moving plate 33, the connecting sleeve 35 on its front side moves synchronously, causing the push-pull rod 36 on the rod inside the connecting sleeve 35 to rotate at an angle. The other end of the push-pull rod 36 is connected to the clamping plate 38 through the rotating shaft 37. Under the pulling force of the push-pull rod 36, the clamping plate 38 slides inward along the sliding rod 22 of the grinding table 2 with the help of the sliders 310 on both sides of the bottom end. As the clamping plate 38 gradually approaches the negative electrode of the lithium battery, the rubber pad 39 on its inner side first contacts the surface of the negative electrode. The elasticity of the rubber pad 39 can prevent the negative electrode from being pinched and at the same time increase the friction to prevent the negative electrode from sliding during grinding, until the clamping plates 38 on both sides firmly clamp the negative electrode.

[0031] The solution uses a PLC as the core control component. The PLC establishes a connection with the electric telescopic pole 32 through RS-485 communication. When the electric telescopic pole 32 needs to be started, the PLC sends a start command to the electric telescopic pole 32, causing the electric telescopic pole 32 to start.

[0032] The working principle of this lithium battery negative electrode polishing equipment will be explained in detail below.

[0033] like Figures 1-5As shown, during use, the negative terminal of the lithium battery to be polished is placed on the top of the polishing table 2. At this time, the electric telescopic rod 32 starts to retract and pulls the moving plate 33 backward. Since the limiting blocks 34 at the upper and lower ends of the moving plate 33 are slidably sleeved on the limiting rod 31 inside the bearing bracket 3, the moving plate 33 will move smoothly along the axis of the limiting rod 31 to avoid deviation. During the movement of the moving plate 33, the connecting sleeve 35 on its front side moves synchronously, causing the push-pull rod 36 on the rod inside the connecting sleeve 35 to rotate at an angle. The other end of the push-pull rod 36 is connected to the clamping plate 38 through the rotating shaft 37. Under the pulling force of the push-pull rod 36, the clamping plate 38 moves with the help of the sliders 310 on both sides of the bottom end. Slide the slide bar 22 along the grinding table 2 inward. As the clamping plate 38 gradually approaches the negative electrode of the lithium battery, the rubber pad 39 on its inner side first contacts the surface of the negative electrode. The elasticity of the rubber pad 39 can prevent the negative electrode from being pinched and increase the friction to prevent the negative electrode from sliding during grinding. Until the clamping plates 38 on both sides firmly clamp the negative electrode, after grinding, the electric telescopic rod 32 drives the moving plate 33 to reset. At this time, the push-pull rod 36 pushes the clamping plate 38 to slide outward along the slide bar 22, releasing the clamping of the negative electrode of the lithium battery. At the same time, the connecting plate 311 on the connecting sleeve 35 moves with the connecting sleeve 35, driving the pusher plate 312 to move forward synchronously. The pusher plate 312 moves forward to push the ground lithium battery forward, realizing the unloading.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
