Problems solved by technology

[0002] In the field of lithium battery manufacturing, the unwinding mechanism is one of the essential equipment for pole piece processing. The conventional unwinding mechanism usually uses a motor to drive the unwinding shaft to move. The direction of the material rotates in the same direction, that is, the motor directly drives the unwinding shaft to rotate, and the power transmitted by the motor to the magnetic powder clutch will constantly modify the output parameters of the motor according to the difference in tension and the diameter of the coil. The program control is also complicated and difficult to control. , making the tension control of the pole piece strip unstable and affecting the pole piece processing
In addition, since the motor directly drives the unwinding shaft to rotate, during the unwinding process, due to the fluctuation of winding and intermediate traction force, it is necessary to continuously optimize the output parameters of the motor, and the excessive tension fluctuation when the equipment starts and stops may easily cause the strip of the pole piece to break. After the tape is broken, it is necessary to manually reconnect the tape, resulting in a waste of labor costs and a waste of pole piece material tape

Abstract

The embodiment of the invention provides a roll material unwinding mechanism and a laser die cutting and slitting all-in-one machine, and relates to the technical field of lithium battery manufacturing. The roll material unwinding mechanism comprises an unwinding shaft, a mounting frame, a magnetic powder clutch and a driving part, the driving part is in transmission connection with an input shaft of the magnetic powder clutch, and an output shaft of the magnetic powder clutch is rotationally assembled on the mounting frame. The unwinding shaft is in transmission connection with the output shaft of the magnetic powder clutch and used for bearing a pole piece material strap, the rotation direction of the input shaft of the magnetic powder clutch is opposite to that of the unwinding shaft, and the magnetic powder clutch is used for adjusting the tension of the unwinding shaft. Compared with the prior art, the roll material unwinding mechanism can prevent a motor from directly driving the unwinding shaft to rotate, so that tension control of the unwinding shaft is more stable, the control process is simplified, and the problem that the pole piece material strap is prone to being broken due to overlarge tension fluctuation during starting and stopping is avoided.
