Winding device and winding method for window-type irregular saddle-shaped coil

Abstract

The invention relates to the technical field of manufacturing processes of window type irregular saddle-shaped coils for compound function electromagnets, in particular to a winding device and method of a window type irregular saddle-shaped coil. The window type irregular saddle-shaped coil comprises step components which are unfolded with two 90-degree flanges on two edges and used for controlling gaps among copper wires of each layer at the 90-degree flanges, the upper edges of wire cakes on each layer are guaranteed to be flush on the same plane after flanging, the step component at one end is horizontally divided into three parts, and gaps are reserved in the middles and used for accommodating copper wire heads, the three parts are fixed on a base plate through locating pins and bolts respectively. A 90-degree back plate is located above the step component with coils unfolded at two ends and used for unfolding two ends of each wire cake to vertical positions layer by layer through a special tool after layer winding, and a saddle shape is formed. The internal quality is good, the performance is reliable, the winding efficiency is high, the cost is low, the boundary dimension and the shape error are small, the stability is excellent, the product consistency is good, the performance of a whole compound electromagnet is modified and improved, the magnetic field index is stable, and the error is small.

Description

technical field [0001] The invention relates to the technical field of manufacturing technology of a window-shaped irregular saddle-shaped coil for a composite function electromagnet, in particular to a winding device and a winding method of a window-shaped irregular saddle-shaped coil. Background technique [0002] With the rapid development of semiconductor technology, the requirements for semiconductor equipment are getting higher and higher, and online equipment requires small size, full functions, stable performance, and low failure rate. Therefore, electromagnets with composite functions such as focusing and deflection came into being. Coils are an indispensable key component of electromagnet equipment, especially the coils of window-type two-pole electromagnets, which not only require reliable internal quality, but also ensure accurate external dimensions. At present, according to the design of electromagnet equipment, there are many types of coils. Saddle coils are ...

Problems solved by technology

[0003] The existing coil winding methods are very effective for conventional saddle-shaped coils, but for the window-shaped irregular saddle-shaped coils of compound dipole magnets with large bending angles, especially the irregular saddle-shaped coils with a single layer as a cake In terms of regular saddle coil winding, not only the requirements for the winding mold are high, but also it is difficult to control its dimensional accuracy
