Abstract

The invention discloses an intelligent lithium battery diaphragm tension control device. The intelligent lithium battery diaphragm tension control device comprises a PLC a driving motor, two servo drivers and a display, the servo drivers are connected with servo motors, incremental encoders are arranged on the servo motors, the output ends of the servo motors are connected with diaphragm transmission rollers through gearboxes, and the two diaphragm transmission rollers are separately located at the input end and the output end of a lithium battery diaphragm. The output end of the driving motoris connected with a marking roller, the marking roller is located at the input end of the lithium battery diaphragm, and a plurality of hole punching cutters are evenly distributed on the end part inthe circumferential direction. The hole punching cutters are matched with the diaphragm transmission roller located at the input end of the lithium battery diaphragm, and a photoelectric sensor is arranged near the output end of the lithium battery diaphragm, and the photoelectric sensor corresponds to the side of the lithium battery diaphragm. The intelligent lithium battery diaphragm tension control device can correct position information of the lithium battery diaphragm in time, a transmission system of the whole lithium battery diaphragm is enabled to be more stable and reliable, and thequality and output of the lithium battery diaphragm are improved.
