[0025] By spirally rotating the threaded rod 13, it spirally pushes the connected trapezoidal block 2 14, and the upper and lower ends of one side of the trapezoidal block 2 14 squeeze the trapezoidal block 12 respectively, so that the two limit assemblies expand to the opposite sides. Through the self-locking of the threaded rod 13, the two limit assemblies maintain a fixed open state, which is convenient for placing the lithium battery diaphragm between the two limit assemblies and improving the clamping convenience. After the placement is completed, the two limit assemblies are reset by rotating the threaded rod 13 in the opposite direction, so that the lithium battery diaphragm between the two limit assemblies is squeezed and fixed, which is convenient for the subsequent lithium battery diaphragm winding operation.

[0026] The sliding plate 5 is provided with a sliding groove 6 and a limiting groove 7 connected thereto. The side wall of the sliding plate 5 is further provided with a trapezoidal groove 8 connected to the sliding groove 6. The trapezoidal block 2 14 and the two trapezoidal blocks 1 12 are respectively located in the limiting groove 7.

[0027] The limiting groove 7 is used to vertically guide the trapezoidal block 2 14 and the two trapezoidal blocks 1 12 so that the trapezoidal block 2 14 and the two trapezoidal blocks 1 12 remain in a vertical state during the movement.

[0028] The limiting assembly includes a clamping block 9, one side of which is fixedly connected to a trapezoidal block 12.

A plurality of trapezoidal blocks 11 are equidistantly fixed to one end of the clamping block 9. The trapezoidal block 11 is slidably connected to the inner wall of the trapezoidal groove 8.

[0029] The spring 10 is used to push the clamping block 9 and generate an expansion force when the clamping block 9 contracts, so that the clamping block 9 can be reset when the contraction force disappears;

The clamping block 9 clamps the lithium battery diaphragm under the action of the spring 10, which is convenient for the subsequent winding operation of the lithium battery diaphragm. The lithium battery diaphragm is wound by the pay-off roller 4. Through the same operation, multiple pay-off rollers 4 with wound lithium battery diaphragms can be prepared in advance, and the fixed plate 1 is dragged to drive the pay-off roller 4 to move, so that the card block is engaged with the card slot, and the pay-off roller 4 can be driven by the motor 18 to realize the film laying operation.
