Description

Technical Field

[0001] The invention relates to the field of transformer production, in particular to an iron core winding device for transformer production. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization.

[0003] During the production of the existing transformer, the coil needs to be manually wound around the outer wall of the transformer core. The production process is to first wind an insulating layer, wind retaining walls on both sides of the insulating layer, manually cut the insulating layer and the retaining wall using scissors, then wind a layer of coil, and repeat the above operation. When cutting the insulating layer and the retaining wall, since the transformer core is in an "I"-shaped structure, manually held scissors are not convenient for fast and stable cutting. In addition, during the cutting process, the worker needs to hold the insulating layer and the outer wall of the retaining wall with the other hand for cutting. Long-term work on the assembly line can easily make the worker feel tired, resulting in operational errors, causing the cutting knife to accidentally injure the other hand, or the cutting length is long, resulting in waste of materials. Therefore, the present invention proposes a core winding device for transformer production. Summary of the invention

[0009] As a further solution of the present invention: the number of the second spur gears is two, and the two second spur gears are symmetrically distributed on the outer walls of the two second fixing columns with the first spur gear as the center.

[0010] As a further solution of the present invention: the inner wall of the second fixed column is provided with a vertical slide groove for matching the vertical movement trajectory of the cutting knife and the support seat, and the vertical slide groove is used to limit the movement direction of the cutting knife and the support seat. A servo motor is installed at one end of the first fixed column, and the output end of the servo motor is connected to the transmission rod through a rotating shaft and a coupling.

[0011] As a further solution of the present invention: the inner wall of the second fixed column is provided with a groove for matching the rotation trajectories of the first rotating block and the second rotating block. When the cutting knife and the support seat are in a closed state, the first rotating block and the second rotating block are in opposite directions.

[0013] As a further solution of the present invention: the inner wall of the movable rod is provided with a sliding groove for matching the outer wall of the positioning rod, and the cross-sections of the movable rod and the positioning rod are both "T"-shaped structures.
