Integrated equipment for battery pole sheet production and cell rolling

Abstract

The invention discloses an integrated equipment for battery pole sheet production and cell rolling, which includes a frame and a control system. The positive electrode sheet delivered by the positive electrode sheet supply device and the negative electrode sheet supply device are installed in the center of the frame. The negative electrode sheet sent by the device, the diaphragm output by the first and second diaphragm supply devices are sequentially wound into a winding device for electric cores in the order of positive electrode sheet, diaphragm, negative electrode sheet, and diaphragm; on the lower left side of the winding device There is a secondary unloading manipulator and a unloading conveyor belt mechanism. The secondary unloading manipulator performs hot hole processing at the same time as unloading, which is convenient and effective; the glue coating mechanism of the positive lug welding device on the frame adopts a cam control structure, which has high precision and stability. OK; the positive lug bracket of the positive lug welding device passes through the frame of the equipment and is installed on the rear side of the frame, and the negative lug bracket of the negative lug welding device passes through the frame of the equipment and is installed on the rear side of the rack , so that the layout of each device on the entire device is more reasonable, and the overall size is effectively reduced.

Description

【Technical field】 [0001] The invention relates to battery production equipment, in particular to an integrated equipment for battery pole sheet production and cell rolling. 【Background technique】 [0002] At present, the production of battery positive and negative electrode sheets and the winding of battery cells are usually completed by two separate equipments. First, the positive and negative electrode sheet production equipment welds tabs on the positive and negative electrode sheets and sticks protective tapes. Finally, according to the requirements of different winding equipment, the positive and negative electrode sheets are cut to a fixed length or rolled into rolls to complete the sheet production work; then, the collected sheets are moved to semi-automatic or fully automatic winding equipment, The pole piece is wound and formed by winding equipment to make a battery cell. [0003] Since two types of equipment are used for sheet production and winding cells, the sta...

AI Technical Summary

Problems solved by technology

[0003] Since two types of equipment are used for sheet production and winding cells, the staff need to transport the collected sheets to the winding equipment, which increases the labor intensity of the staff, delays time, and affects work efficiency

[0004] At the same time, during film production, the requirements for material rolls are relatively high. The current technology is difficult to achieve consistent alignment of rolls and winding materials, and it is easy to increase the difficulty of correcting deviations in the subsequent winding process, so that the positive and negative electrodes Skew will cause inconsistency in the alignment of the cell end face, which greatly affects the quality of the battery cell; during winding, due to manual direct contact, it is easy to cause cross-contamination of the positive and negative electrodes, which directly affects the final battery quality.
