Laminating machine capable of driving film discharging by rotary loading

Abstract

The invention relates to a laminating machine capable of driving film discharging by rotary loading. The laminating machine comprises a rotary loading mechanism, a positive pole piece trough, a positive pole piece calibration console, a negative pole piece trough, a negative pole piece calibration console, a lamination table and a film discharging mechanism, wherein the rotary loading mechanism is used for transferring pole pieces, and a big turntable which rotates in a reciprocating manner and is provided with four feeding arms is arranged at the upper part of the rotary loading mechanism; the positive pole piece trough, the positive pole piece calibration console, the negative pole piece trough, the negative pole piece calibration console and the lamination table are distributed along the periphery of the rotary loading mechanism; and the film discharging mechanism is arranged above the lamination table and driven by the big turntable which rotates in a reciprocating manner. When the big turntable rotates in a reciprocating manner, the two front feeding arms are used for respectively transferring positive pole pieces in the positive pole piece trough and negative pole pieces in the negative pole piece trough into the positive pole piece calibration console and the negative pole piece calibration console to be positioned; and the two rear feeding arms are used for respectively transferring the positioned positive pole pieces in the positive pole piece calibration console and the positioned negative pole pieces in the negative pole piece calibration console onto the lamination table and enabling the positive pole pieces and the negative pole pieces to be sequentially and alternately laminated with repeated Z-shaped films intermittently discharged by the film discharging mechanism. The laminating machine disclosed by the invention is simple in mechanisms for loading, transferring and laminating the positive pole pieces and the negative pole pieces in the circumferential direction, small in motion inertia, more stable in operation, small in occupied area and low in manufacturing cost.
