Abstract

The invention discloses a constant force coiling machine for MH-Ni dynamic cylinder battery coiling, comprising a frame and a device baseplate provided with a battery pole plate base, a membrane base, a pole plate guiding mechanism and a pin mechanism. The device controls a magnetic powder brake by membrane tension to realize membrane constant tension control, controls the coiling compressing mechanism by PLC to realize constant tension coiling and adopts the telescopic pole plate guiding mechanism to ensure flatness of an core end surface of the coiling as well as arranges a membrane grasping mechanism to realize an automatic feed in of a positive and a negative membrane. In the coiling process, under a circumstance that a diameter of the core of the coiling ranges up and down and degrees of tightness of the coiling core in and out are consistent, the constant force coiling machine, is flat at the end surface and low labor intensity in the operation personnel and great in product quality.

Description

technical field

[0001] The invention relates to battery manufacturing equipment, in particular to a winding machine for nickel-hydrogen power cylinder batteries. Background technique

[0002] The traditional nickel-hydrogen battery winding machine includes a frame and an equipment substrate fixed on the frame. The equipment substrate is equipped with a battery plate seat, a diaphragm seat, a diaphragm shaft, a plate guide mechanism and a needle rolling mechanism. The center hole of the diaphragm seat is pierced, and the diaphragm is placed on the diaphragm seat. During the winding process, the inner and outer tightness of the wound cell is inconsistent, and the battery’s electro-hydraulic distribution is uneven in the later stage, and the end surface of the cell is uneven. The product quality is directly affected by man-made. Factors have great influence. Although the lithium-ion battery winding machines currently on the market have a diaphragm tension mechanism, the tensio...
