Polar column polishing device for aluminum shell battery

Abstract

The invention discloses a polar column polishing device for an aluminum shell battery. The polar column polishing device comprises a supporting table panel, a milling cutter and a driving mechanism, wherein a linear guide rail and a substrate plate slidably assembled with the linear guide rail are arranged on the supporting table panel, and a guide slot for placing a battery and a positioning aircylinder located on one side of the guide slot are arranged on the substrate plate; the milling cutter mechanism is located at one end of the moving direction of the substrate plate, the milling cutter is connected to the driving mechanism and is driven by the driving mechanism to mill, a limiting mechanism is arranged on the outer side of the milling cutter, and the end, close to the substrate plate, of the limiting mechanism is longer than the end, close to the substrate plate, of the milling cutter, so that the limiting mechanism leans against a cover plate of the battery when the milling cutter leans against the polar column of the battery. The polar column polishing device solves the problem that during re-operation for rack of fusion, a conventional operating means is poor in weldingspot eliminating effect, low in efficiency and heavy in pollution, so that the surface structure of the polar column is protected effectively and the consistency of the battery is improved.

Description

technical field [0001] The technical field of battery manufacturing of the present invention, in particular relates to a grinding device for poles of aluminum shell batteries. Background technique [0002] In the production process of batteries, the welding of batteries is the key process of assembling battery packs, but the reprocessing of batteries with poor welding has always been a difficult problem for the entire industry. After welding, there are solder joints on the battery poles. The removal status of the solder joints directly affects the yield rate of re-soldering. If the solder joints are not completely removed, it will cause false soldering and missing soldering. If the column welding depth exceeds the standard, it is very easy to cause safety accidents such as liquid leakage in the later stage. The traditional manual direct grinding operation has low efficiency, huge differences in solder joint removal status, and low grinding yield. Contents of the invention...

[0002] In the production process of batteries, the welding of batteries is the key process of assembling battery packs, but the reprocessing of batteries with poor welding has always been a difficult problem for the entire industry

After welding, there are solder joints on the battery poles. The removal status of the solder joints directly affects the yield rate of re-soldering. If the solder joints are not completely removed, it will cause false soldering and missing soldering. If the welding depth of the column exceeds the standard, it is very easy to cause safety accidents such as liquid leakage in the later stage

The traditional manual direct grinding operation has low efficiency, huge difference in solder joint removal status, and low grinding yield rate
