Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery production, in particular to an insulating component for cylindrical battery production and circulation. Background Art
[0002] During the production process of large cylindrical batteries, the opening formation process and other processes will be operated with power on. In order to ensure the performance and safety of the battery, the large cylindrical batteries in the process flow need to be insulated. In order to avoid short circuit failures of the positive and negative electrodes of the cylindrical battery during the circulation process, an insulating gasket is generally attached to the positive end of the battery. However, this type of insulating gasket requires special mold cutting and a fixing device, and cannot be reused, which greatly increases the cost. For this reason, the applicant has designed an insulating component, which is made of elastic insulating material into a cylindrical structure, which is sleeved on the cylindrical battery, solving the problem that the insulating gasket is not easy to fix, and it can be reused. However, this structure uses elastic force to wrap around the battery, making it more troublesome to remove the sleeve. Utility Model Content
[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide an insulating component with reasonable structural design, which can be quickly installed and removed, and is easy to operate and use.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] An insulating component for the production and circulation of cylindrical batteries, characterized in that it includes a disc-shaped insulating sheet, the middle part of the insulating sheet has a coaxial protruding convex column, the inner side of the convex column has a concave pole sealing cavity, the diameter of the pole sealing cavity is greater than the pole diameter of the cylindrical battery, and the depth is greater than the pole height of the cylindrical battery; the edge of the insulating sheet has an insulating sleeve extending in a direction away from the convex column, the inner diameter of the insulating sleeve matches the diameter of the cylindrical battery, so that the insulating sleeve can be mounted on the cylindrical battery with a clearance fit.
[0006] In the above structure, since the insulating sleeve and the cylindrical battery are clearance-matched, the friction between the insulating sleeve and the cylindrical battery is small, so that the insulating sleeve can be installed or removed more easily, and the operation is more convenient.
[0007] Furthermore, a magnet is provided on the insulating sheet, and the magnet is insulated and wrapped in the insulating sheet.
[0008] In this way, the insulating sheet can be adsorbed on the battery shell by a magnet, so that the insulating component can be more reliably mounted on the cylindrical battery.
[0009] Furthermore, a plurality of magnets are evenly distributed around the boss.
[0010] Furthermore, the insulating sheet has ventilation holes extending therethrough.
[0011] In this way, when the insulating component is installed and removed, the air in the insulating sleeve can be exchanged with the outside through the vent hole, thereby reducing the resistance of installation or removal and making the operation more convenient.
[0012] Furthermore, a plurality of vent holes are evenly distributed around the convex column.
[0013] Furthermore, the diameter of the vent hole is 2 to 5 mm.
[0014] Furthermore, one end of the insulating sleeve facing away from the insulating sheet has a bell mouth that expands outwards.
[0015] In this way, the insulating sleeve can be better aligned with the cylindrical battery sleeve.
[0016] Furthermore, the connection between the insulating sheet and the insulating sleeve bulges outward from the inside to form a buffer ring, and the inner diameter of the buffer ring is larger than the diameter of the cylindrical battery.
[0017] In this way, a gap can be formed between the edge of the cylindrical battery and the buffer ring by the buffer ring that expands from the inside to the outside. Once the cylindrical battery is knocked over, the buffer ring can also protect the edge of the cylindrical battery to avoid edge bumps.
[0018] Furthermore, the insulating sheet and the insulating sleeve are made of acid- and alkali-resistant polymer materials.
[0019] Furthermore, the insulating sheet, the protruding column and the insulating sleeve are integrally formed.
[0020] In summary, the utility model has the advantages of reasonable structural design, rapid assembly and disassembly, and convenient operation and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described in detail below in conjunction with the embodiments.
[0026] When implementing: Figure 1 and Figure 2 As shown, an insulating assembly for cylindrical battery production and circulation includes a disc-shaped insulating sheet 1, the middle part of the insulating sheet 1 has a coaxial protruding protrusion 2, the inner side of the protrusion 2 has a pole sealing cavity 3 formed by a depression, the diameter of the pole sealing cavity 3 is greater than the pole diameter of the cylindrical battery, and the depth is greater than the pole height of the cylindrical battery; the edge of the insulating sheet 1 has an insulating sleeve 4 extending in a direction away from the protrusion 2, the inner diameter of the insulating sleeve 4 matches the diameter of the cylindrical battery, so that the insulating sleeve 4 can be sleeved on the cylindrical battery with clearance fit; the insulating sheet 1, the protrusion 2 and the insulating sleeve 4 are integrally processed and made of acid and alkali resistant polymer materials. The connection between the insulating sheet 1 and the insulating sleeve 4 bulges from the inside to the outside to form a buffer ring 7, the inner diameter of the buffer ring 7 is greater than the diameter of the cylindrical battery; the end of the insulating sleeve 4 away from the insulating sheet 1 has a trumpet mouth that expands outward.
[0027] The insulating sheet 1 is provided with a magnet 5, which is insulated and wrapped in the insulating sheet 1, and multiple magnets 5 are evenly distributed around the boss 2; at the same time, the insulating sheet 1 has a through-set ventilation hole 6, the diameter of the ventilation hole 6 is 2 to 5 mm, and multiple ventilation holes 6 are evenly distributed around the boss 2.
[0028] When using the insulating assembly of this embodiment, align the bell mouth of the insulating sleeve with the positive electrode of the cylindrical battery and sleeve it on the cylindrical battery. During the sleeve installation process, the air in the insulating sleeve is discharged through the vents, thereby reducing the resistance during the installation process. At the same time, since the insulating sleeve and the cylindrical battery are in a clearance fit, the contact area between the insulating sleeve and the outer wall of the cylindrical battery is smaller, and the friction resistance is also smaller, so it is easier to sleeve. After being sleeved in place, the magnet will be adsorbed on the negative electrode shell, thereby preventing the insulating sleeve from falling off. During disassembly, air enters the insulating sleeve from the vents, so that the insulating assembly can be quickly removed. In addition, by using a buffer ring that expands from the inside to the outside, a gap can be formed between the edge of the cylindrical battery and the buffer ring, such as Figure 3 and Figure 4 As shown, once the cylindrical battery is knocked over, the buffer ring can also protect the edge of the cylindrical battery to avoid edge bumps.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
