Technical Field
[0001] This utility model specifically relates to a coated pad for a lithium-ion battery. Background Technology
[0002] During the research and development and trial production of lithium-ion batteries, multiple coating designs often need to be met, including coating width and thinning. Currently, a single coating pad can often only meet one or a few coating size designs. When the pad is incompatible, it has to be redesigned, which greatly increases costs and reduces production efficiency. To address this, we propose a coating pad for lithium-ion batteries.

[0014] It facilitates the coating process by using two secondary gaskets.
[0015] Preferably, the guide groove is convex in shape.
[0016] It facilitates flow during coating.
[0017] Preferably, a locking and limiting hole is provided through the inner side of the main gasket, and multiple locking and limiting holes are evenly distributed along the circumference of the guide groove.
[0018] It facilitates quick and easy connection and fixation of the main gasket to the external coating equipment.
[0019] Preferably, the main gasket is T-shaped, and the lower ends of the two side walls of the main gasket are rounded.
[0020] This helps reduce the risk of scratches on the outside caused by the corners of the main gasket sidewall.
[0021] Preferably, the main gasket and the secondary gasket are made of the same material, and two secondary gaskets are provided.
[0022] It facilitates coating through two secondary gaskets.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] This patent allows for maximum adaptation to different coating design requirements by replacing secondary gaskets of different lengths and chamfers with the main gasket. It can be widely compatible with a variety of coating designs at minimal cost, and also requires rapid changeover, saving time on rework and redesign, thus greatly improving production efficiency.

[0029] 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.
[0030] Please see Figures 1-3 This utility model provides a technical solution: a coated pad for a lithium-ion battery, comprising:
[0031] Main gasket 1, wherein a guide groove 4 is provided on the inner side of the main gasket 1;
[0032] The auxiliary gasket 7 is disposed on the upper inner side of the guide groove 4, and the auxiliary gasket 7 is detachably connected to the main gasket 1;
[0033] The auxiliary gasket 7 has a chamfer 8 at one end.
[0034] The auxiliary gasket 7 is easy to disassemble and install, so that multiple auxiliary gaskets 7 can be processed. The length of the auxiliary gasket 7 can be designed in multiple ways so that different auxiliary gaskets 7 can be selectively assembled when needed to meet different coating requirements.
[0035] In this embodiment, preferably, the secondary gasket 7 is "L" shaped.
[0036] This improves the stability of the sub-gasket 7 after installation, ensuring that the sub-gasket 7 does not move arbitrarily during coating.
[0037] In this embodiment, preferably, the side wall of the auxiliary gasket 7 has a snap-fit groove 6, and the inner side of the main gasket 1 has an auxiliary gasket snap-fit groove 3 that cooperates with the snap-fit groove 6.
[0038] It facilitates quick and easy engagement of the secondary gasket 7 with the main gasket 1, improving the convenience of disassembling the secondary gasket 7 and making it easy to replace.
[0039] In this embodiment, preferably, there are two auxiliary gasket slots 3, and the two auxiliary gasket slots 3 are symmetrically distributed.
[0040] The auxiliary gasket 7 can be quickly installed and connected through the auxiliary gasket slot 3, and then the coating action can be completed through the two auxiliary gaskets 7.
[0041] In this embodiment, preferably, the guide groove 4 is convex in shape.
[0042] It facilitates flow during coating.
[0043] In this embodiment, preferably, a locking limit hole 5 is provided through the inner side of the main gasket 1, and multiple locking limit holes 5 are evenly distributed around the circumference of the guide groove 4.
[0044] This facilitates quick connection and fixation of the main gasket 1 to the external coating equipment. The main gasket 1 is quickly installed and fixed by engaging the locking limit hole 5 with the bolt.
[0045] In this embodiment, preferably, the main gasket 1 is "T" shaped, and the lower ends of the two side walls of the main gasket 1 are provided with rounded corners.
[0046] This design helps reduce the risk of scratches on the outside from the corner of the main gasket 1 sidewall, and the "T" shape also helps ensure the stability of the main gasket 1 when it is installed on the coating equipment.
[0047] In this embodiment, preferably, the main gasket 1 and the secondary gasket 7 are made of the same material, and two secondary gaskets 7 are provided.
[0048] It facilitates coating through two auxiliary gaskets 7, ensuring a good coating effect.
[0049] The working principle and usage process of this utility model are as follows: When in use, the main gasket 1 is designed in the shape of a "U". The upper end is provided with a secondary gasket slot 3, the middle part is a guide groove 4, and the lower end is provided with a locking limit hole 5. The slot 6 and the secondary gasket 7 form the main body, and a chamfer 8 is provided at the front end of the secondary gasket 7. The secondary gasket 7 can be embedded in the secondary gasket slot 3 of the main gasket 1, thus forming a quick-change gasket for lithium-ion battery coating.
[0050] The secondary gasket 7 is a replaceable gasket. One main gasket 1 can contain multiple secondary gaskets 7. The length of the secondary gasket 7 can be designed as a gradient length, and it can be made in the form of 2.5mm, 5mm, 7.5mm, and 10mm. By changing the secondary gasket 7 of different lengths, different coating width design requirements can be met. In addition, the secondary gasket 7 can also be made into a gradient chamfered gasket on the chamfer 8, and can be made in the form of 2x1mm, 2x2mm, 3x1mm, and 3x2mm. By changing the secondary gasket 7 with different chamfers, different coating thinning designs can be met. It is not limited to the combination of secondary gasket 7 and chamfer 8 to meet a wider range of coating design requirements. Just by matching the secondary gasket 7 of different sizes with the secondary gasket slot 3 of the main gasket 1, the gasket corresponding to the coating design requirements can be quickly adapted, realizing quick gasket change.
