Problems solved by technology
[0003]
However, in a high-speed laminating machine, due to the extremely fast left and right movement of the lamination platform and the high acceleration of the diaphragm movement, the diaphragm is prone to shake, so that the boundary sensed by the position sensor is not the real boundary position of the diaphragm, resulting in deviation correction uneven
[0004] In view of the above problems, it is necessary to develop a diaphragm correction device to solve the problem of uneven correction caused by the deviation of the boundary positioning caused by the vibration of the diaphragm

The invention discloses a deviation rectifying device for a diaphragm, and relates to the technical field of lithium battery manufacturing equipment. The deviation rectifying device for the diaphragm comprises a bracket, a deviation rectifying assembly, a smoothing assembly and a position sensor. The deviation rectifying assembly comprises two deviation rectifying rollers, the two deviation rectifying rollers extend in the first direction and are arranged on the bracket at intervals, and the two deviation rectifying rollers can rotate along the axes of the deviation rectifying rollers; the smoothing assembly comprises a fixing seat and two smoothing pieces arranged on the fixing seat at intervals, the fixing seat is slidably arranged on the bracket in the first direction, and the two smoothing pieces are used for smoothing the edge of the diaphragm; and the position sensor is arranged on the fixing seat and located between the smoothing pieces and the deviation rectifying rollers. According to the deviation rectifying device for the diaphragm, the diaphragm can be smoothed before the position sensor detects the boundary of the diaphragm, thus the accuracy of boundary detection is improved, and the deviation rectifying effect is improved.
Description
technical field [0001] The invention relates to the technical field of lithium battery manufacturing equipment, in particular to a deflection correcting device for a diaphragm. Background technique [0002] At present, in the manufacturing process of large-scale lithium-ion power batteries, a laminating machine is usually used to assemble the positive and negative pole pieces of the lithium-ion battery pole piece and the separator in a Z-shaped stack to make a pole piece. In the manufacturing process of the diaphragm, it is generally necessary to use a diaphragm winding device to wind the diaphragm. However, deviations are prone to occur during the winding process of the diaphragm, which eventually leads to irregular stacking of the diaphragm. Therefore, it is necessary to use a deviation correction device to correct the deviation of the diaphragm and adjust the position of the diaphragm during the winding process. In the traditional correction mechanism, the sensor is used...
