[0005] However, in this winding device and method, the positive and negative electrode sheets 3', 4' are fed from the same direction, that is, the positive and negative electrode sheets overlap each other during the feeding process, and the cobalt acid in the negative electrode sheet 4' Lithium easily falls onto the positive sheet 3', causing a short circuit
Moreover, the structure of the feeding mechanism that ensures that the positive and negative plates 3' and 4' overlap in the same direction is complex and inefficient, which is not conducive to mass production of products

Embodiment Construction
[0034] See Figure 1 to Figure 4 An embodiment of the battery pole piece winding device designed in the present invention includes a positive electrode sheet supply mechanism 1, and a negative electrode sheet supply mechanism 2 spaced apart from the positive electrode sheet supply mechanism 1 in the horizontal direction and staggered in the vertical direction. , Provide the diaphragm supply mechanism 3 between the positive and negative electrode sheet supply mechanisms, and the upper and lower winding needles 4 between the positive and negative electrode sheet supply mechanisms.
[0035] In this embodiment, the positive and negative electrode sheet supply mechanisms 1 and 2 are respectively located on different levels and distributed on the left and right sides. The position of the negative electrode sheet supply mechanism 2 on the right is higher than the position of the positive electrode sheet supply mechanism 1 on the left. . The positive and negative plates 5, 6 of the batt...
