Positive and negative electrode welding and membrane covering assembly line of battery

Abstract

The invention provides a positive and negative electrode welding and membrane covering assembly line of a battery. The assembly line comprises a positive and negative electrode welding machine, a membrane covering machine and a cache mechanism, wherein the positive and negative electrode welding machine comprises a battery charging conveyor module and a welding concentricity detector module; the membrane covering machine comprises a battery membrane covering module and a battery boxing module; the cache mechanism comprises a cache box, a battery charging channel and a battery discharging channel. The assembly line can be used for carrying out charging, conveying, positive electrode welding, positive electrode concentricity detection, positive electrode welding, negative electrode concentricity detection, sorting of accepted weld products, battery conveying caching, battery internal resistance testing, battery meson assembly, battery membrane covering, battery membrane baking, sorting of accepted battery products, battery boxing, discharging and recycling in a full automatic way and integrates all these functions into a whole; the assembly line has the advantages of high intelligent level, high automatic operation degree, high detection accuracy, high welding and assembling working efficiency, high yield, good quality effect and low cost; in addition, the assembly line can produce over 55 batteries per minute.

Description

Technical field [0001] The invention relates to a battery positive and negative electrode welding and covering film assembly line. Background technique [0002] The traditional welding and assembly of the battery is mainly operated by human hands. The screw and nut are mainly welded to the positive and negative electrodes of the battery by hand. The manual welding operation method cannot detect the concentricity of the screw and nut after welding. It causes large welding deviation, poor quality effect and low yield. After the welding process is completed, it is necessary to manually complete the detection of battery resistance, manual assembly of meson film, manual cover film, electric blower film, manual packing, etc. The test and assembly process is low in efficiency and high in cost. Therefore, in view of the shortcomings of the above-mentioned problems in traditional battery welding and assembly technology, the applicant has developed a fully automatic battery loading, trans...

Problems solved by technology

[0002] The traditional welding and assembly of batteries is mainly done by hand. It mainly welds the screws and nuts to the positive and negative electrodes of the battery respectively by hand. The manual welding operation method cannot detect the concentricity of the screws and nuts after welding. The welding deviation is large, the quality effect is poor, and the yield is low. After the welding process is completed, it needs to manually complete the detection of the battery resistance, manually assemble the meson film, artificially cover the film, electric heating and blowing the film, and manually pack the box. Test and assembly process, low efficiency and high cost
