Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to a dual-cell stacking device. Background Technology

[0002] In existing technologies, a stacking robot picks up positive and negative electrode sheets from the sheet carrier and, in conjunction with the oscillation of the separator assembly, alternately places them on the stacking table to form a single cell. Due to structural limitations of the existing sheet carrier, stacking table, and robot, only one cell can be stacked at a time. The stacking table stacks one cell at a time, and only after the completed cell is transferred out of the stacking table can the stacking of the next cell begin. Existing technologies can only produce one cell at a time, resulting in low cell production efficiency. Improving efficiency requires increasing the electrode sheet feeding speed and stacking speed, but increasing the operating speed of the mechanism has an upper limit and will exacerbate equipment vibration, adversely affecting the equipment's operating accuracy and CCD sampling accuracy, thus impacting the cell production accuracy.
