Description

Technical Field

[0002] The string welding machine is one of the important equipment in the production process of battery cells. It is used to weld multiple battery cells into a string of battery strings. The welded battery strings need to be cut according to the predetermined length. The existing battery string cutting mechanism generally adopts the upper and lower cutter mechanisms arranged longitudinally. The lower cutter mechanism is fixedly arranged. The upper cutter mechanism is driven downward by the cylinder to cooperate with the lower cutter mechanism to cut the welding ribbon. The battery string cutting mechanism with this structure will cause the welding ribbon to tilt downward after cutting. The cut fixed-length battery string may contact the conveyor belt during transportation, causing the fixed-length battery string to shift during transportation, thereby affecting the transmission accuracy of the subsequent battery string. Therefore, a battery string cutting mechanism and a string welding machine are provided to solve the above problems. Utility Model Content
