Description

Technical Field

[0001] The invention relates to the technical field of electronic component production equipment, in particular to an electronic transformer wire starting spiral winding device. Background Art

[0002] The transformer is a commonly used electronic component, which mainly winds coils on the skeleton and pins. Due to the development of electronic miniaturization, a large number of electronic components are installed electronically, so electronic transformers are also produced. In order to improve the production efficiency of transformers, automated equipment is usually used for winding. The existing automated winding equipment sets the winding assembly for supplying wires to three-axis motion during winding, and the wire clamping mechanism fixes the wire end, and then winds the wire on the starting pin. This method will cause the wires to cross on the starting pins of the transformer and the wires to be suspended at the skeleton, which will lead to the following: 1. When soldering, there will be tin accumulation, the hanging wire will become thinner, etc., which will lead to an increase in the defective rate of broken wires. 2. When laser stripping, the skin of the hanging wire will be stripped off first, and the part blocked by the hanging wire cannot be stripped by the laser, which will affect the subsequent tinning effect.
