[0024] The following is a more specific embodiment:
[0025] In this embodiment, the battery electrode sheet rolling machine winding automatic tape splicing assembly is provided with a threading chain buffer compensation mechanism. The automatic tape changing and splicing device has a tape guiding mechanism that can move in the vertical and horizontal directions. The tape guiding mechanism is composed of a sprocket group. By changing the position of the side plate, the relative position of the sprocket group changes to compensate for the length difference of the tape guiding chain caused by displacement. The tape splicing mechanism includes a moving frame unit, a telescopic frame unit, and a tape splicing rubber roller assembly. The entire tape splicing mechanism is arranged on the mounting frame and is located between the first winding unit and the second winding unit. The moving frame is arranged on the mounting frame and reciprocates between the first unwinding unit and the second unwinding unit.

The tape splicing assembly is arranged on the telescopic frame and moves or telescopes with the moving frame and the telescopic frame.

When the main side plate unit 1 moving up and down moves up and down, the length of the tape guiding chain 9 inside the automatic tape splicing assembly does not change, which can ensure the normal use of the tape guiding chain. Among the tape guiding chains between the small sprocket assembly II and the small sprocket assembly III, and between the small sprocket assembly III and the small sprocket assembly IV, they are always in a parallel state. When the telescopic side plate unit 2 moves left and right and telescopes, they compensate for each other's lengths, so that the length of the tape guiding chain 9 inside the automatic tape splicing assembly does not change, which can ensure the normal use of the tape guiding chain. By changing the moving positions of the main side plate unit 1 moving up and down and the telescopic side plate unit 2 moving left and right, the tape splicing rubber roller assembly 10 can avoid contacting the electrode sheet during production, thereby extending the service life of the tape splicing rubber roller and reducing production costs.
