Self-cleaning battery manufacturing equipment

Abstract

The invention provides self-cleaning type battery manufacturing equipment. The equipment comprises a support plate for supporting the equipment, a strip-shaped conveyed pole piece foil material, welding equipment for welding a current collector on the pole piece foil material, and a roller shaft self-cleaning mechanism for automatically cleaning each conveying roller shaft for conveying the polepiece foil material, and relates to the field of battery manufacturing. According to the self-cleaning type battery manufacturing equipment, a special roller shaft transmission mode for transmitting the pole piece foil material is arranged so that roller shaft cleaning is automatically performed along with production and transmission. Dust on the pole piece foil material can be synchronously cleaned in a semi-closed manner. The pole piece foil material and the roller shaft are cleaned in a complementary manner. Therefore, problems that the roller shaft and the pole piece foil material are easily contaminated by dust, the dust on the roller shaft and the dust on the pole piece foil material are difficult to clean synchronously, the roller shaft and the pole piece foil material often interfere with each other and a trade-off state is generated, a welding effect is directly influenced by the dust, and quality of a finished product is influenced when a common battery is manufactured and processed by a sheet making machine are effectively solved.

Problems solved by technology

[0002] In the process of battery processing, it needs to be processed by a sheet making machine, and the current collector is welded on the pole piece foil by an ultrasonic welding machine. The sheet foil is generally very long and will be guided by multiple rollers. Therefore, under the conditions of long exposure workshop time and complex air environment, generally the cutting of the end of the pole sheet foil will generate more dust, and the dust is easy to fall on the conveyor. The pole piece foil, and then contaminated on the transmission roller, which makes the subsequent pole piece foil may also be contaminated with dust, the existence of these dust will affect the ultrasonic welding process, resulting in the occurrence of virtual welding, and then may As a result, there are defects in the produced batteries, so it is very important to remove dust. Due to the large number of rollers and their irregular distribution, the current main method is to stop the machine and clean each roller one by one after the equipment has been running for a period of time, and then for the electrode sheet foil The dust on the surface is generally only blown away by the wind. On the one hand, this method cannot completely reduce the dust, and the dust may fall back again, and the dust generated by the wind will also fall on the electrode foil far away from the welding machine, causing the roll The number of shaft cleaning increases. When the general battery manufacturing is processed by the film making machine, the roller shaft and the pole piece foil are easily contaminated with dust. The dust cleaning on the roller shaft and the pole piece foil is difficult to synchronize and often interferes with each other. These dusts directly affect the effect of welding, and then affect the quality of finished products, so a self-cleaning battery manufacturing equipment is needed
