Description

Technical Field

[0001] The present invention relates to the technical field of low - voltage foil - wound coil production, and particularly to a positioning device for conductive bars of low - voltage foil - wound coils. Background Art

[0002] The positioning device for conductive bars of low - voltage foil - wound coils is a special device used in the manufacture of low - voltage winding coils in power equipment (such as transformers, motors, generators, etc.), aiming to achieve precise positioning of conductive bars (usually aluminum foil or copper foil) during the winding process. By ensuring that the conductive bars are accurately and stably placed in the predetermined positions, the winding accuracy of the coil can be improved, the winding performance can be ensured, and losses can be reduced. This device is particularly suitable for the precise manufacturing requirements of low - voltage windings in the power industry.

[0003] The positioning device for conductive bars of low - voltage foil - wound coils ensures the stability and accuracy of the conductive bars during the winding process through precise positioning, orientation, and automatic adjustment, thereby improving the quality and performance of the windings. It reduces manual intervention through automated operations, improves production efficiency, and has strong adaptability and intelligent control, providing an efficient solution for the power and electronics industries.

[0004] During the winding process of the low - voltage foil - type coil of a dry - type transformer, although the spacer rods can be placed between the conductive bars manually to achieve the structural support and spacing function of the coil, this manual operation method also has some disadvantages. When manually placing the spacer rods, the proficiency and operation speed of the operator will affect the uniformity of the position and spacing of the spacer rods. This may lead to inconsistent spacing between the copper foils, which in turn affects the electrical performance and mechanical strength of the coil, and may even cause short - circuits or deformation of the winding. At the same time, manually placing the spacer rods is a labor - intensive process and takes a long time to complete. This results in low efficiency in the winding process, especially in a production environment where a large number of coils need to be wound, and the time cost of manual operation is relatively high.
