Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a magnetic ring winding device for flat wires. Background Technique

[0002] In some high-power electronic products, such as photovoltaic transformers, inverters, reactors, new energy charging piles, communication products, etc., flat wires are required. Flat wires usually carry large currents, have large wire diameters, are difficult to produce and manufacture, and consume a large amount of man-hours. In the traditional method of winding magnetic ring products, the magnetic ring needs to be cut into two halves. After the wire is wound into a hollow coil, the coil is then installed into the cut magnetic ring, and then the magnetic ring is assembled and tied with a steel strip. Another method is to wind the wire into a hollow coil and then stretch the coil, and manually rotate the coil one by one into the magnetic ring. The production processes of the above two methods are quite time-consuming and have low production efficiency.

[0003] In the prior art, the patent number is CN207624537U, which provides a device for winding flat wires on a magnetic ring, including a hollow wire-passing and forming guide rail. One end of the wire-passing and forming guide rail is provided with a wire feeding mechanism, and the other end of the wire-passing and forming guide rail is provided with a bending wire forming U-shaped guide wheel that can move back and forth in the vertical direction. An annular magnetic core is arranged below the bending wire forming U-shaped guide wheel; the wire feeding mechanism and the bending wire forming U-shaped guide wheel are both arranged at intervals with the wire-passing and forming guide rail; a protruding end R corner is arranged in the middle of one end of the wire-passing and forming guide rail close to the bending wire forming U-shaped guide wheel. The flat wire is wound around the magnetic core through the cooperation of the wire feeding mechanism and the U-shaped guide wheel. However, the above structure has the following problems: First, the requirement for the wire guiding accuracy is high. If the wire deviates, it is easy to cause the entire product to be scrapped, and there is a safety hazard if the operator is near the device; Second, the bending direction of the wire needs to be adjusted through the R corner arranged on the forming guide rail, and the bending angle cannot be adjusted, and the universality cannot be satisfied for different sizes of annular magnetic cores.
