Description

Technical Field

[0001] This utility model relates to the technical field of foil winding devices, and in particular to a foil winding device for transformer core coils. Background Technology

[0002] Foil winding is a core technology in transformer winding manufacturing. It specifically refers to the process system that uses copper foil or aluminum foil to replace traditional wires for precision winding. It has advantages such as better electromagnetic performance of coils, tighter and stronger winding, and better shock resistance. It is mainly used in low-voltage and high-current scenarios to improve equipment performance.

[0003] Currently, the main method used is to wind transformer core coils using foil winding devices. For example, the invention patent with patent number 202011343905.0, entitled "A Winding Device and Operating Method for an Integrated Winding Machine for Amorphous Three-Dimensional Winded Core Transformer Wire and Foil", states that in this patent, a rotary drive mechanism drives the winding gear set to rotate, which can form copper foil outside the winding gear set.

[0004] However, once the copper foil is wound around the winding gear assembly and forms a ring shape, it is extremely difficult to detach from the winding gear assembly. This makes it difficult to remove the ring-shaped copper foil, affecting the manufacturing process of the transformer core coil.

[0005] Therefore, how to design a transformer core coil foil winding device that is easy to detach and remove is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This invention provides a transformer core coil foil winding device, which solves the technical problem that the existing formed copper foil is not easy to remove.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a transformer core coil foil winding device, comprising: a fixed frame, a first winding roller, a rotary drive mechanism, and a telescopic winding mechanism.

[0008] The first winding roller rotates on the fixed frame; the copper foil rotates outside the first winding roller; the rotation drive mechanism is located on one side of the copper foil and its fixed part is fixed on the fixed frame, and the rotation axis of its rotating part is parallel to the axis of the first winding roller; the telescopic winding mechanism includes a telescopic drive part and a fixed winding member and a movable winding member for forming the iron core coil, the fixed winding member is fixed on the rotating part of the rotation drive mechanism; the telescopic direction of the telescopic drive part is arranged along the axis perpendicular to the rotation axis of the rotating part; the fixed winding member and the movable winding member are respectively fixed to the fixed end and the telescopic end of the telescopic drive part, so that the copper foil that has rotated out of the first winding roller is first formed outside the fixed winding member and the movable winding member after the distance is increased, and then the distance between the fixed winding member and the movable winding member is reduced, so that the formed copper foil can be separated from the fixed winding member and the movable winding member.

[0009] The beneficial effects of this utility model are: it improves the structure of the traditional transformer core coil foil winding device, and uses the rotating part of the rotary drive mechanism to drive the fixed winding member to rotate, so that the copper foil that has rotated out of the first winding roller is wound on the fixed winding member and the movable winding member after the distance has increased. When the copper foil is wound, the distance between the fixed winding member and the movable winding member after the increase is the same as the diameter of the transformer core coil. Then, the telescopic end of the telescopic drive part drives the movable winding member to move, reducing the distance between the fixed winding member and the movable winding member. When detaching, the distance between the fixed winding member and the movable winding member after the decrease is 0.6 to 0.8 times the diameter of the transformer core coil, which makes it easier for the formed copper foil to detach from the fixed winding member and the movable winding member, thereby improving the production efficiency of the transformer core coil.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the rotary drive mechanism includes a drive motor, a reducer, and a rotary shaft. The drive motor is the fixed part of the rotary drive mechanism and is fixed on the fixed frame. The reducer is adjacent to the drive motor and is fixed on the fixed frame. The input shaft of the reducer is drively connected to the output shaft of the drive motor. The rotary shaft is the rotating part of the rotary drive mechanism and is arranged along the rotation axis of the rotating part. The rotary shaft is drively connected to the output shaft of the reducer. The fixed winding member is fixed on the rotary shaft.

[0012] Furthermore, the fixed winding component is a fixed box, and the movable winding component is a movable box. The two adjacent and perpendicularly distributed side walls of the fixed box are the first side wall and the second side wall, respectively. The first side wall of the fixed box is arranged perpendicular to the rotation axis of the rotating part and fixed to the rotating part. The second side wall of the fixed box is arranged opposite to the movable box and is provided with an inlet / outlet sliding hole. The movable box slides within the fixed box along the rotation axis perpendicular to the rotating part and can slide out of the inlet / outlet sliding hole. The movable box has an opening on one side corresponding to the fixed box and defines a functional module installation area between the movable box and the fixed box. The copper foil is formed on the fixed box and the movable box. The telescopic drive part is located within the functional module installation area, and its fixed end is fixed to the fixed box, and its telescopic end is fixed to the movable box, so as to slide the movable box into the fixed box, so that the formed copper foil can be detached from the fixed winding component and the movable winding component.

[0013] The further beneficial effect of adopting the above is that the movable box slides inside the fixed box. Since the fixed end of the telescopic drive is fixed on the fixed box and the telescopic end is fixed on the movable box, the movable box can slide into the fixed box when the copper foil is formed outside the fixed box and the movable box, thereby reducing the overall volume of the fixed box and the movable box and making it easier for the formed copper foil to detach from the fixed winding component and the movable winding component.

[0014] Furthermore, the telescopic drive unit includes a support frame, a screw, a nut, a worm gear, a worm, an operating shaft, and an operating wheel, all located in the functional module mounting area. The support frame is the fixed end of the telescopic drive unit and is fixed to the fixed box. The screw is the telescopic end of the telescopic drive unit and rotates on the movable box along the rotation axis perpendicular to the rotating part. The nut is fixed to the support frame and threadedly connected to the screw. The worm gear is sleeved outside the nut. The worm meshes with the worm gear so that when the worm rotates, the screw rotates in conjunction with it, causing the movable box to slide out of the fixed box or slide into the fixed box. The operating shaft is fixed to the worm and one end of it rotates out of the fixed box. The operating wheel is located outside the fixed box and fixed to the extended end of the operating shaft.

[0015] The further beneficial effects of the above are: rotating the operating wheel, the linkage operating shaft and worm gear rotate, which drives the worm wheel to rotate. Since the worm wheel is fixed outside the nut, the screw can rotate and move, making it easy for the movable box to extend into or out of the fixed box.

[0016] Furthermore, the telescopic winding mechanism also includes a clamping screw, a clamping plate, and a clamping nut. The clamping screw is fixed to the fixed winding member along the rotation axis perpendicular to the rotating part. The clamping plate is provided with a through hole. The clamping screw passes through the through hole. The clamping nut is threaded onto the clamping screw to push the clamping plate to press against the outside of the copper foil.

[0017] The further beneficial effect of the above is that when the copper foil is wound on the fixed winding member and the movable winding member, rotating the clamping nut and pushing the clamping plate close to the copper foil can press the clamping plate firmly on the copper foil and prevent the copper foil from curling up.

[0018] Furthermore, it also includes a second winding roller, which is located on one side of the first winding roller and its two ends are respectively rotatably connected to the two fixed frames. An insulating sheet is wound on the second winding roller. The insulating sheet that turns out of the second winding roller and the copper foil that turns out of the first winding roller are alternately wound around the fixed winding member and the movable winding member.

[0019] Furthermore, it also includes a pressing roller and two rotating frames, the two rotating frames rotating about the rotation axis of the rotating part on the two fixed frames respectively; the pressing roller is arranged along the rotation axis of the rotating part and its two ends are fixed on the two rotating frames respectively, so as to press against the copper foil on the fixed frames as the two rotating frames rotate.

[0020] The further beneficial effect of the above is that pressing the pressure roller against the copper foil outside the first winding roller can prevent the copper foil from curling up.

[0021] Furthermore, it also includes a controller, which is fixed on the mounting frame and electrically connected to the rotary drive mechanism. Attached Figure Description
