Description

Technical Field

The invention belongs to the field of foil coil winding machines, and particularly relates to a double-servo bias correction low-voltage foil coil winding machine.

Background

A foil coil winder (hereinafter referred to as a foil winder) is a special transformer for manufacturing a low-voltage coil in a round or square or rectangular coil shape. The main function of the coil is that the foil tape (copper tape or aluminum tape) is tightly wound on a die with tension, the turns are wound with wide tape-shaped insulating materials with tension, two ends of the coil are insulated around the ends, and the inner side and the outer side of the coil are welded with leads respectively. The tension control system and the deviation rectifying structure system are two main functional systems of the foil winding machine. The two functional systems complement each other during coil winding, and play a decisive role in the overall quality of coil winding. The consistency of the compactness and the radial dimension of coil winding is mainly determined by the precision of tension control by a tension control system, and the advantages and disadvantages of a deviation correcting structure system determine the coil end face leveling degree, namely the axial dimension error. With the development of more than ten years, on one hand, because the insulation width of some coil ends is only 5-10 mm, higher requirements are put forward on the end surface level of the coil foil strips, and on the other hand, because the labor cost is higher and higher, in order to improve the efficiency and reduce the cost, great clear demands are made on the automation of equipment, the acceleration of winding speed and the stability of winding. The performance of the correction system of the existing foil winding machine and the automation level of each functional component are difficult to meet the current use requirements.
