[0019] Referring to Figure 1 With Figure 2 An electrode coating tool shown in the figure, including base 1, base 1 is the support base of the whole tool, made of materials with certain strength and rigidity and insulation, such as high-strength plastic and the like. First and second protective sheets 2 and 3 are arranged at intervals on the base 1, and a feeding channel 4 is formed between the first and second protective sheets 2 and 3 for conveying film material. The first protective sheet 2 has a straight sheet part 21 and an arc sheet part 22, and the straight sheet part 21 is fixedly connected with the base 1 by welding or one-piece forming and the like, to ensure the firmness and stability of the connection. The arc sheet part 22 is not connected with the base 1 and has elasticity, and this elastic design can make the arc sheet part 22 produce certain deformation when subjected to external force, thereby pressing the film material coated on the outer surface of the electrode (not shown in the figure) and improving the tightness and uniformity of the coating. A positioning rod 5 is arranged on the inner side of the arc sheet part 22 of the base 1, and the positioning rod 5 is fixed on the base 1 or mounted on the base 1 through a bearing or the like rotary support part. The electrode can be sleeved on the positioning rod 5 and rotate relative to the positioning rod 5, or the electrode is fixedly installed on the positioning rod 5 and rotates relative to the base 1 through the positioning rod 5, so that the electrode can rotate smoothly during the coating process, realizing uniform coating of the film material.

[0020] In some possible embodiments, the inner side of the arc sheet part 22 is further provided with a circular arc pressing sheet 7, the circular arc pressing sheet 7 extends from the end of the arc sheet part 22 to the straight sheet part 21, and the circular arc pressing sheet 7 is coaxially arranged with the positioning rod 5, and the inner diameter size of the circular arc pressing sheet 7 is greater than the outer diameter size of the electrode. Further, the circular arc pressing sheet 7 is integrally formed with the first protective sheet 2, and is processed and formed at the same time with the first protective sheet 2 by using high-strength plastic and the like, to ensure the integrity and strength of the structure. The connection between the circular arc pressing sheet 7 and the arc sheet part 22 is rounded, so that the film coated on the outer surface of the electrode is smoothly pressed at this place, avoiding scratching the film.

[0021] In some possible embodiments, the width of the feeding channel 4 gradually decreases from the straight piece 21 to the arc piece 22, and the gradually-changing feeding channel 4 design can guide the thin film material to gradually fit the outer surface of the electrode, so that the thin film material can be more smoothly unfolded and positioned during the coating process. Further, the connecting piece 23 is arranged between the straight piece 21 and the arc piece 22, and the connecting piece 23 is inclined from the straight piece 21 to the arc piece 22 and gradually approaches the second guard piece 3, thereby playing a dual role of connection and guidance.

[0022] In some possible embodiments, the base 1 is provided with a placement groove 9 for installing a planar needle bearing (not shown in the figure) at a position outside the periphery of the positioning rod 5. The planar needle bearing is installed in the placement groove 9, which can reduce the frictional resistance of the electrode during rotation, so that the electrode can rotate more smoothly and stably.

[0023] In some possible embodiments, the height of the first guard piece 2 protruding from the base 1 is less than the height of the second guard piece 3 protruding from the base 1, and the width of the thin film is greater than the height of the first guard piece 2, so as to facilitate the hand or equipment to pull the thin film out of the arc piece 22 and smoothly attach the thin film to the electrode.

[0024] In some possible embodiments, one end of the second guard piece 3 close to the positioning rod 5 is not connected to the base 1, and the extension length of the one end of the second guard piece 3 is greater than the extension length of the arc piece 22, which can better support and position the thin film material during the coating process.

[0025] In some possible embodiments, the feeding channel 4 is provided with a lifting step 10 at the bottom, one end of the lifting step 10 protrudes from the arc piece 22 and gradually converges to the side surface of the second guard piece 3, and further, the surface of the lifting step 10 is smooth, which reduces the friction between the thin film material and the lifting step 10 during the feeding process, thereby preventing the thin film from being scratched or damaged.

[0026] In actual use, firstly, one end of the film material is put into the entrance of the feeding channel 4 and gradually pushed to the arc piece 22 along the feeding channel 4, the lifting step 10 and the connecting piece 23 position and guide the film material, so that the film material can be smoothly conveyed along the feeding channel 4 and aligned with the position required to be coated on the electrode. The operator installs the electrode on the positioning rod 5 and ensures that the electrode can rotate relative to the axis of the positioning rod 5. When the film material passes through the arc piece 22, it is automatically attached to the outer surface of the electrode or the operator attaches the end of the film material to the outer surface of the electrode, then the operator starts the rotating device or manually drives the electrode to rotate, so that the electrode rotates on the positioning rod 5, and the rotation of the electrode pulls the film material, so that the film material is uniformly wound and coated on the outer surface of the electrode. When the film material is coated for several layers, the film material is stably attached to the outer surface of the electrode under the action of the arc pressing piece 7 and the elastic restoring force of the arc piece 22, and finally the operator cuts off the film material and drives the electrode to rotate, so that the arc pressing piece 7 tightly presses and stably connects the cut end of the film material to the electrode, so that the coating work of the electrode is completed.

[0027] The electrode coating tool has the advantages of simple structure, convenient operation, high coating quality, can effectively solve the problems in the prior art, and has good application prospect and market promotion value.

[0028] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any change or replacement within the technical range disclosed by the utility model should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
