Wire harness tension adjusting system of winding machine

Abstract

The invention provides a wire harness tension adjusting system of a winding machine. A feedback control loop composed of a tension detector, a main controller, a wire harness brake, an auxiliary controller and a wireless communication module is arranged, so that the tension force on an wire harness can be automatically adjusted to a preset value, and a previous operation method of manually monitoring and adjusting the tension force of the wire harness is changed; and the efficiency of adjusting the tension of the wire harness during winding of the winding machine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of winding machines, in particular to a wire harness tension adjustment system of a winding machine. Background technique [0002] The toroidal coil winding machine is a kind of equipment widely used in the power electronics industry. It is mainly used to wind the enameled wire on the ring frame, and wrap the iron core ring frame according to the coil process requirements. The equipment consists of two parts: the host machine and the wire pay-off mechanism. Its working principle is to drive the wire storage ring to rotate through the reverse rotation of the shuttle to wind the enameled wire on the pay-off frame into the wire storage ring, and then pull out the wire storage ring by the forward rotation of the shuttle. The enameled wire in it is wound on the iron core. However, when the annular iron core is clamped, it is generally difficult to ensure that the cross section of the annular iron core is located...

AI Technical Summary

Problems solved by technology

However, when the annular iron core is clamped, it is generally difficult to ensure that the cross section of the annular iron core is located at the center of the wire storage ring, resulting in a section between the iron core and the ring gear picker during the rotation of the ring gear. The enameled wire always increases gradually when passing the first half turn, and gradually shortens when the ring gear turns through the second half turn, so during the winding process, the tension of the enameled wire in the first half turn is greater than that in the second half turn

The enameled wire will become loose within a certain angle during the winding process, that is, the tension of the enameled wire is zero, which makes the iron core shake during the winding process, the winding pitch is uneven, and the tensile stress of the wire is different. When the product is in stock, the stress is released and the coil is deformed, which affects the performance and quality of the final product
