Description

[Technical field]

[0001] The invention relates to a high-speed automatic winding technology, in particular to a multi-wire parallel winding and cross winding device and a winding machine thereof. [Background technology]

[0002] A winding machine is a device that winds a linear object onto a specific workpiece. It is usually used for winding copper wire. Most existing winding machines are combined into a highly automated device through motors, electric components, pneumatic components, transmission devices, sensors, control systems, etc. When the winding machine is working, the winding skeleton is generally fixed on the fixture, and the winding skeleton is rotated circumferentially and moved axially along with the fixture through automatic wire arrangement, winding head, wire cutting, wire twisting, loading and unloading. The wire is wound on the winding skeleton to form a coil.

[0003] In the existing winding machines, most of the winding components can only arrange single-wire or double-wire wires. Since the pin distance on the winding component cannot be changed, the coil enameled wire wound on the winding frame cannot fit perfectly, making the wire package too large, which leads to excessive parasitic capacitance. In addition, the conventional parallel winding method has too many turns and occupies a large space, which causes the temperature of the coil to rise during use. In addition, due to the excessive amount of enameled wire, there are bends and overlaps, which makes it difficult to wind the enameled wire flat, resulting in high leakage inductance of the capacitor. At the same time, loose winding will also aggravate the leakage inductance. [Summary of the invention]
