Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery processing technology, specifically to a tab chamfering device for lithium battery processing. Background Technology
[0002] The term "soft-pack battery" is a name used to distinguish it from cylindrical and prismatic hard-shell batteries. Its internal composition (positive electrode, negative electrode, separator, electrolyte) is not much different from that of prismatic and cylindrical lithium batteries. The biggest difference is that soft-pack batteries use an aluminum-plastic composite film as the outer shell, while prismatic and cylindrical batteries use metal materials as the outer shell.
[0003] In this regard, the existing technology patent announcement number: CN218533054U discloses a chamfering device for processing the tabs of soft-pack lithium batteries, including a base, with columns installed on both sides of the base, an adjustment seat fixedly installed between the two sets of columns, and a mating seat provided on the top of the base.
[0004] However, in actual use, the operation of adjusting the spacing of the extension tube is quite cumbersome. Also, the top surface of the battery tab is not limited during the chamfering process. Therefore, improving and perfecting the above-mentioned issues is an urgent problem to be solved. Utility Model Content

[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] Please see Figures 1-5 One embodiment provided by this utility model:
[0026] A chamfering device for electrode tabs in lithium battery processing. The cylinder body 4 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a base plate 1, a support plate 2 installed on the back of the base plate 1, a side plate 3 installed on the front surface of the support plate 2, a drive assembly installed inside the side plate 3, a chamfering assembly installed at the lower end of the drive assembly, and a limit assembly installed on the surface of the base plate 1.
[0027] The drive assembly includes a cylinder body 4, which is installed inside the side plate 3, and a connecting seat 5 is installed at the lower end of the cylinder body 4.
[0028] The chamfering assembly includes a first mounting block 6, a first chamfering ring 7, and a second chamfering ring 11. The first mounting block 6 is mounted on the right side surface of the connecting seat 5, and the first chamfering ring 7 is mounted on the right side surface of the first mounting block 6. A fixing cylinder 8 is mounted at the front end of the first mounting block 6, and a stabilizing column 9 is mounted inside the fixing cylinder 8. Limiting arc-shaped blocks 12 are mounted on the inner side walls of both the first chamfering ring 7 and the second chamfering ring 11. A second mounting block 10 is mounted at the end of the stabilizing column 9 away from the fixing cylinder 8, and the second chamfering ring 11 is mounted on the right side surface of the second mounting block 10. A fixing groove 13 is formed inside both the fixing cylinder 8 and the stabilizing column 9, and a fixing column 14 is mounted inside the fixing groove 13. In use, the battery tabs are first positioned. Then, the distance between the first chamfering ring 7 and the second chamfering ring 11 is adjusted according to the size of the battery. During adjustment, the stabilizing column 9 moves inside the fixing cylinder 8. After moving to the appropriate size, the fixing column 14 is installed inside the fixing groove 13 to fix the fixing cylinder 8 and the stabilizing column 9. Then, the cylinder body 4 drives the connecting seat 5 to move downward. At this time, the connecting seat 5 will drive the first chamfering ring 7 and the second chamfering ring 11 downward. At this time, the first chamfering ring 7 and the second chamfering ring 11 will be chamfered on both sides of the battery tabs. After chamfering, the limiting arc block 12 will abut against the upper surface of the first chamfering ring 7 and the second chamfering ring 11 to ensure that the chamfering operation is completed. Therefore, this setting, through the cooperation of the drive component and the chamfering component, can quickly adjust the distance between the first chamfering ring 7 and the second chamfering ring 11, and it is convenient to fix after adjustment. At the same time, it can also ensure the stability of chamfering.
[0029] The limiting assembly includes a limiting plate 15, which is installed on the top surface of the base plate 1. A large groove 16 is formed on the surface of the limiting plate 15, and a rotating column 17 is inserted inside the limiting plate 15. An abutment block 18 is installed on the outer surface of the rotating column 17, which is movably installed inside the limiting plate 15. When the battery tab is placed inside the large groove 16, rotating the rotating column 17 causes the abutment block 18 to rotate, causing it to adhere to the upper surface of the battery tab. This effectively limits the battery position during the chamfering process, resulting in a good overall limiting effect. This design, through the limiting assembly, pre-limits and fixes the lithium battery to be chamfered, thus preventing subsequent displacement of the lithium battery and chamfering failure.
[0030] Working principle: When the operator uses this device, first connect the device to an external power source to provide power support. During use, first limit the battery tabs, and then adjust the distance between the first chamfering ring 7 and the second chamfering ring 11 according to the size of the battery. During adjustment, the stabilizing column 9 moves inside the fixing cylinder 8. When it moves to the appropriate size, the fixing column 14 is installed inside the fixing groove 13 to fix the fixing cylinder 8 and the stabilizing column 9. Then, the cylinder body 4 drives the connecting seat 5 to move downward. At this time, the connecting seat 5 will drive the first chamfering ring 7 and the second chamfering ring 11 downward. At this time, the first chamfering ring 7 and the second chamfering ring 11 will perform chamfering operation on both sides of the battery tabs. At the same time, after chamfering, the limiting arc block 12 will abut against the upper surface of the first chamfering ring 7 and the second chamfering ring 11 to ensure that the chamfering operation is completed.
[0031] At this time, the battery tab is placed inside the large groove 16, and then the rotating column 17 is rotated, which will drive the contact block 18 to rotate. At this time, the contact block 18 will fit against the upper surface of the battery tab, thereby limiting the position of the battery during the chamfering process. The above is the working principle of this utility model.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
