[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] Please see Figures 1-9 As shown, the purpose of this embodiment is to provide a polymer battery head wrapping machine, including a fixing plate 1, a plurality of through holes 12 are provided through the fixing plate 1, a battery 4 is inserted into the through holes 12, a plurality of clamps 2 are slidably provided on the fixing plate 1, and the clamps 2 are used to clamp and fix the battery 4, and a wrapping part 3 for wrapping the battery head is fixedly provided on one side of the fixing plate 1.

[0032] The clamp 2 includes clamping plates 21 arranged symmetrically on the top and bottom. One end of each clamping plate 21 is fixedly provided with an arc-shaped block 22 for clamping the battery 4, and a fixing ring 23 is fixedly provided between the other ends of the two clamping plates 21.

[0033] An elastic pad 5 is fixedly provided on the inner wall of the through hole 12. The battery 4 is inserted into the elastic pad 5. The elastic pad 5 is made of highly elastic silicone, which can provide sufficient friction to clamp the battery 4 when it is inserted. It can also maintain good elastic recovery during long-term use, ensuring that the clamping effect is always consistent. In addition, the elastic pad 5 can adapt to batteries 4 of different sizes.

[0034] Furthermore, the elastic pad 5 gradually increases in diameter from the insertion end of the battery 4 to the other end, forming a cone-shaped structure. This structure serves both as a guide and allows the battery 4 to be gradually clamped by the elastic pad 5 during insertion, thus achieving initial fixation. As the battery 4 is inserted deeper, the elastic pad 5 gradually unfolds and adheres to the surface of the battery 4, ensuring that the battery 4 is stably clamped within the through hole 12.

[0035] The arc-shaped block 22 is arc-shaped and is typically made of a material with a certain degree of elasticity, such as high-quality alloy steel or special plastic, to ensure that it provides sufficient clamping force when clamping the battery 4, while avoiding damage to the surface of the battery 4 due to excessive compression. Furthermore, the curvature of the arc-shaped block 22 is smaller than that of a circle. When the clamp 2 clamps the battery 4, the arc-shaped block 22 will be slightly deformed by the compression of the battery 4. This deformation is elastic, meaning that when the battery 4 is released, the arc-shaped block 22 can return to its original shape, allowing it to fit tightly against the surface of the battery 4, achieving stable clamping regardless of the diameter of the battery 4.

[0036] When clamping batteries 4 of different diameters, the arc-shaped blocks 22 automatically adjust their clamping force and contact area according to the size of the battery 4. For batteries 4 with smaller diameters, the arc-shaped blocks 22 will press together more to provide stronger clamping force; while for batteries 4 with larger diameters, the arc-shaped blocks 22 will be relatively dispersed, but still maintain sufficient contact area to ensure stable clamping.

[0037] Connecting tubes 231 are fixedly installed at both ends of the fixing ring 23. One end of the connecting tube 231 is fixedly connected to the fixing ring 23, and the other end is fixedly connected to the side wall of the clamping plate 21. The connecting tube 231 is a corrugated tube, which allows it to deform under external force and quickly return to its original shape after the external force is removed. When the user needs to manually press the upper and lower clamping plates 21, the corrugated tube connecting tube 231 can be easily folded and compressed, allowing the other end of the clamping plate 21 to be raised or lowered. The corrugated tube structure also has a certain shock absorption and buffering effect, which can reduce the vibration and impact on the battery 4 during the wrapping process to a certain extent.

[0038] A spring 232 is fixedly installed inside the connecting tube 231. One end of the spring 232 is fixedly connected to the fixing ring 23, and the other end of the spring 232 is fixedly connected to the side wall of the clamping plate 21. The clamping function of the clamp 2 is realized by the elasticity of the spring 232. Since the spring 232 is installed inside the connecting tube 231, it may be subjected to various external forces and impacts during long-term use. If it is not effectively protected, it is easy to deform or twist, thereby affecting the clamping effect and service life of the clamp 2. The pleated structure of the connecting tube 231 can not only provide a certain buffer and shock absorption for the spring 232, but also prevent external objects from directly contacting the spring 232, thereby effectively avoiding damage to the spring 232.

[0039] Symmetrical grooves 11 are provided near the upper and lower ends of the through hole 12. The clamp 2 is slidably installed in the grooves 11. The grooves 11 are H-shaped and the cross sections at both ends of the grooves 11 are inverted trapezoidal.

[0040] Initially, the clamp 2 is located at the left end of the slide groove 11. When it is necessary to clamp and fix the battery 4, the user first presses the clamp plate 21, causing the connecting tube 231 to fold and compress. At the same time, the spring 232 is also compressed and stores energy. As the connecting tube 231 and the spring 232 are compressed, the upper and lower ends of the clamp plate 21 at the pressing end will gradually move closer until the clamp plate 21 is parallel to the middle of the slide groove 11. Then, the clamp 2 is slid along the direction of the slide groove 11, so that it slides from the left end to the right end of the slide groove 11. When the clamp 2 slides to the right end of the slide groove 11, the clamp plate 21 is gradually released. At this time, the spring 232 will release the stored energy and push the other end of the clamp plate 21 to move closer together, thereby clamping the battery 4. Due to the elastic recovery effect of the corrugated connecting tube 231, the clamp plate 21 will fit tightly against the surface of the battery 4, achieving a stable clamping effect. Moreover, the inverted trapezoidal cross-sections at both ends of the slide groove 11 can prevent the clamp 2 from accidentally sliding due to external forces to a certain extent.

[0041] A limiting groove 111 is formed on one side of the inner wall of the slide groove 11, and a limiting block 211 is fixedly provided on the inner wall of the clamping plate 21. The limiting block 211 is slidably installed in the limiting groove 111. The existence of the limiting groove 111 provides a clear guide and limiting function for the clamp 2, so that the clamp 2 can always maintain a stable horizontal position during movement. When the clamp 2 slides to the right end of the slide groove 11, the limiting block 211 will be locked at the end of the limiting groove 111, thereby fixing the horizontal position of the clamp 2. This not only prevents the clamp 2 from accidentally sliding due to external force, but also ensures that the clamping plate 21 can fit tightly against the surface of the battery 4, achieving a stable clamping effect.

[0042] In practical use, the battery 4, which needs to be wrapped with adhesive, is inserted into the elastic pad 5 through one end of the through hole 12 and initially fixed by its clamping force. In the initial state, the clamp 2 is located at the left end of the slide groove 11. Pressing one end of the clamping plate 21 causes the corrugated pipe connecting pipe 231 to fold and compress. When the clamping plate 21 is parallel to the middle of the slide groove 11, the clamp 2 is slid along the direction of the slide groove 11, so that it slides from the left end to the right end of the slide groove 11. During the sliding process, the limiting block 211 slides in the limiting groove 111 to ensure that the clamp 2 maintains a stable horizontal position. When the clamp 2 slides into the slide groove 111, the clamp 2 is fixed in the left end of the slide groove 111. When the right end of 1 is reached, the clamp 21 is gradually released. At this time, the spring 232 gradually returns to its original state, so that the other end of the clamp 21 approaches each other, and the arc block 22 clamps the battery 4. Then, the glue-wrapping part 3 is started to begin the glue-wrapping operation on the head of the battery 4. After the glue-wrapping is completed, the glue-wrapping part 3 is closed, and one end of the clamp 21 is pressed, so that the spring 232 is compressed again. At the same time, the bellows connecting pipe 231 is folded and compressed, and the clamp 2 is slid from the right end of the slide groove 11 back to the left end along the direction of the slide groove 11. When the clamp 2 returns to the initial position, the clamp 21 is released, and the battery 4 with the glue-wrapped part is taken out.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
