Description

Technical Field

[0001] The utility model belongs to the technical field of lithium-ion battery processing equipment, and particularly relates to an automatic wiping device for the tabs of cylindrical lithium-ion batteries. Background Art

[0002] The tabs produced using aluminum strips, nickel strips, and nickel-plated steel strips are commonly used in cylindrical lithium-ion batteries. During the manufacturing process of the tabs, they will be contaminated with oil. Before the production process of welding the tabs to the electrode sheets, it is necessary to remove the oil to prevent subsequent side reactions between the battery and the oil from degrading the battery quality. Currently, manual wiping is used, but there may be omissions, it requires long-term fixed-point work, and it is difficult to control the single dip amount of the wiping solvent, which cannot guarantee the wiping effect and has poor practicability. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to achieve automatic wiping of the oil on the tabs.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is as follows:

[0005] An automatic wiping device for the tabs of cylindrical lithium-ion batteries, including a tab disk, an automatic dispensing machine, a tab wiping device, and a roller. The tab wiping device includes two wiping disks arranged radially, and the upper wiping disk is connected to the outlet of the automatic dispensing machine through a pipeline. The tabs wound on the tab disk pass through the roller and then pass through the tab wiping device after being bent.

[0006] Further, the tabs pass through the middle of the two wiping disks and are in close contact with the two wiping disks.

[0007] Further, the wiping disks are made of dust-free paper or sponge.

[0008] Further, the automatic dispensing machine includes a storage tank and an automatic dispensing valve. Both the storage tank and the automatic dispensing valve are connected to an external independent air compressor. The tab wiping solvent is stored in the storage tank, and the storage tank and the automatic dispensing valve are connected through a pipeline.

[0009] Further, the tab wiping solvent is anhydrous ethanol.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1) Adjust the supply frequency and single supply amount of anhydrous ethanol according to the oil amount, accurately control the usage amount of the wiping solvent, and have good economy;

[0012] 2) The automatic dispensing machine automatically controls the supply of anhydrous ethanol, reduces the labor intensity of workers, and saves labor and time costs;

[0013] 3) The upper and lower wiping discs of the tab wiping device are in close contact with the tab passing between them, achieving uniform and comprehensive wiping of the tab and ensuring the effect of removing oil stains.

[0014] 4) The tab wound on the tab disc is gradually eliminated from bending deformation through the forward and reverse winding of the roller, facilitating wiping and subsequent spot welding. Description of the Drawings

[0020] Embodiment 1

[0021] Refer to Figure 1, including an ear tab disc 1, an automatic dispensing machine 2, an ear tab wiping device 3 and a roller 4. The ear tab wiping device 3 is provided with two wiping discs in the radial direction that are in close contact with each other, and the upper wiping disc is connected to the outlet of the automatic dispensing machine 2 through a pipeline. The ear tabs wound on the ear tab disc 1 pass through between the two wiping discs of the ear tab wiping device 3 after being continuously bent by the roller 4. The material of the wiping disc is dust-free paper or sponge, and the solvent used for wiping is anhydrous ethanol. After starting to work, the solution in the upper wiping disc will diffuse into the lower wiping disc, thereby achieving sufficient wiping of the ear tabs passing through the wiping disc.

[0022] The automatic dispensing machine 2 includes a storage tank 201 and an automatic dispensing valve 202. Both the storage tank 201 and the automatic dispensing valve 202 are connected to an external independent air compressor. The wiping solvent is stored in the storage tank 201, and the air compressor presses air into the storage tank 201. The wiping solvent enters the automatic dispensing valve 202 through the pipeline between the storage tank 201 and the automatic dispensing valve 202.

[0023] The automatic dispensing valve 202 is MY-405 of Shenzhen Dali Cheng Plastic Hardware Products Co., Ltd., and a tail micrometer is used for micro adjustment. The minimum glue discharge amount is 0.01 ml. By adjusting the tail micrometer, the single solvent supply amount can be changed. By adjusting the air supply frequency of the air compressor connected to the automatic dispensing valve 202, the supply frequency of the automatic dispensing valve 202 to the solvent can be changed.
