Example Embodiment

[0027] Please refer to Figure 1 to Figure 3 As shown, it shows the specific structure of the preferred embodiment of the present invention. A lithium battery pole piece punching and forming machine includes a frame 10, a driving device 20, a transmission mechanism 30, a lifting frame 40, and a punching machine. The die 50 and the punching die 50 have a hanging die rod 51, an upper die 52 and a lower die 53, and the driving device 20 drives the lifting frame 40, the hanging die rod 51 and the upper die 52 through the transmission mechanism 30 to lift.

[0028] Wherein, the frame 10 includes a bottom plate 11, a top plate 12, and a plurality of uprights 13, the uprights 13 are connected between the bottom plate 11 and the top plate 12, and the top plate 12 is provided with two side upright plates 14 for mounting the transmission shaft.

[0029] The lifting frame 40 includes a sheave block 41 at the upper end, a seat plate 42 at the lower end, and a plurality of longitudinally extend...

Abstract

The invention discloses a lithium battery electrode piece cutting and forming machine comprising a drive device, a transmission mechanism, a lifting frame and a cutting die. The cutting die comprises a die hanging rod, an upper die unit and a lower die unit; the drive device drives the lifting frame, the die hanging rod and the upper die unit to lift through the transmission mechanism; a cutting trimming device is arranged between the lifting frame and the die hanging rod. On one hand, the die hanging rod is fixed to an upper oblique block of the cutting trimming device, a lower oblique block is driven to move transversely by adjusting a trimming screw so as to drive the fitted upper oblique block to move vertically, the longitudinal movement of the die hanging rod is implemented, and the cutting height can be trimmed; on the other hand, a bearing shaft is arranged on an eccentric wheel as designed, the eccentric wheel is protected, and the service life is prolonged. In the whole moving process, the eccentric wheel is installed on the transmission shaft to rotate and rolls in a racetrack-shaped hole of a grooved wheel block to drive the grooved wheel block to move vertically; the entire operation is stable, impact is resisted, and noise is low.

Description

technical field [0001] The invention relates to the technology in the field of lithium battery production equipment, in particular to a lithium battery pole piece punching forming machine and a punching fine-tuning device. Background technique [0002] The stacked lithium battery is made of multi-layer positive and negative pole pieces. These pole pieces are always cut from the whole pole piece that has been coated and rolled. With the development of science and technology, in response to this problem, people have designed a pole piece cutting and forming process according to the steps of manual processing. There are mainly two types of cutting mechanisms in the market at present: one The servo drives the eccentric shaft to drive the connecting rod for punching (pole sheet punching and forming machine 201120444953.9). The main disadvantage of this device is that the connection between the eccentric shaft and the connecting rod is easy to wear and produce a gap, and the punch...
