Problems solved by technology

[0002] In the existing lithium battery cell production technology, in the manufacturing equipment that completes the pole piece winding process, generally a tension buffer control structure is required between the two driving rollers to eliminate the speed error between the two driving rollers. The tension buffer mechanism is used to dynamically compensate the error value between the driving rollers to ensure a relatively constant tension state during operation. Because the tension is too high, the pole piece will be torn and deformed, and the product will be unqualified if the tension is too small; The winding of the pole piece is in a loose state, which leads to uneven curling, which affects the quality of the product and the subsequent process; while in the prior art, the effect of tension control is not very good, and the tension of the pole piece cannot be kept in a stable state

Abstract

A tension buffer mechanism comprises a driving device, a fixing plate, a roller mounting plate, a distance feedback device, a pole plate passing roller group and a tension detecting device; the rollermounting plate is slidably connected with the fixing plate, the driving device is used for driving the roller mounting plate to slide, the electrode sheet passing roller group is arranged on one sideof the roller mounting plate, The tension detecting device is arranged at one end of the fixing plate, and the pole piece passing roller group is arranged opposite to the tension detecting device. The tension detecting device is used for detecting the pole piece tension and feeding back to the external control system, and the distance feedback device is used for detecting the moving distance of the roller mounting plate and feeding back to the external control system. By adopting the structure of the invention, the tension buffer and the detection of the pole piece are realized through the cooperation of the tension detection device and the distance feedback device, so that the tension fluctuation of the pole piece is stable, the running stability of the whole machine running belt is improved, and the tension of the whole machine running belt is stabilized.
