Technical Field

[0001] This invention relates to the field of transformer manufacturing technology, and more specifically to a transformer coil winding device. Background Technology

[0002] Transformers are fundamental equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. They are devices that use the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. Their main functions include voltage transformation, current transformation, impedance transformation, isolation and voltage stabilization.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-6This invention discloses a transformer coil winding device, comprising a primary coil 1, a primary coil frame 2, a winding coil 3, and a winding frame 4.

The guide frame 6 is located between the primary coil frame 2 and the winding frame 4. The guide frame 6 is provided with a vertical drive mechanism and a through groove Ⅰ6.1 that extends laterally through both sides of the guide frame 6. The motor base 7 is located within the through groove Ⅰ6.1. The output end of the drive mechanism is connected to the motor base 7 in the through groove I 6.1. The drive motor base 7 slides vertically in the through groove I 6.1. The adjustment motor 8 is mounted on the motor base 7. The output shaft of the adjustment motor 8 is connected to the lead screw 9. The lead screw 9 is located between the original bobbin 1 and the winding bobbin 3 and the axes of the three are parallel.

Two guide wheels 11 arranged vertically and horizontally are rotatably arranged in the through groove II 10.2.

[0019] In a specific implementation of this invention, since the original bobbin 1 and the winding bobbin 3 may not be the same size, during the winding process, the wire is not always transported in a straight line from the original bobbin 1 and the guide seat 10 to the winding bobbin 3. To prevent the wire from being bent and scratched by the guide seat 10 during the transport process, a limiting roller 12 is provided. The limiting roller 12 is located at the opening edge of the through groove II 10.2 of the guide seat 10. The limiting roller 12 is rotatably set and its axis is parallel to the edge line of the opening. It can be set at all four edges of the opening of the through groove II 10.2, or at the left and right edges. The lower end of the through groove II 10.2 can also be open. When using this structure, the lower end does not need to be provided with the limiting roller 12. The original drum frame 2 and the winding frame 4 are support bases. Two of each can be set, located at the two ends of the original drum 1 and the winding drum 3 respectively, or one can be set. In this example, one is set.

During installation, the original cylinder 1 and the winding cylinder 3 are respectively fitted onto the cylindrical shaft 13, and the nut 16 is screwed onto the stud 15. The original cylinder 1 and the winding cylinder 3 can be fixed on the cylindrical shaft 13 by the baffle 14 and the nut 16. Disassembly is done by reversing the operation. The vertical drive mechanism is an electric telescopic rod. The output end of the electric telescopic rod extends vertically into the through slot I 6.1 and connects to the motor base 7. That is, the output end of the electric telescopic rod is connected to the upper end of the U-shaped frame, and the lower end of the U-shaped frame is connected to both sides of the motor base 7.
