Technical Field

[0001] The utility model relates to the technical field of winding dies, in particular to an automatic winding die for an electronic coil. Background Art

[0002] A coil generally refers to a wire winding in a ring shape. The most common coil applications include motors, inductors, transformers, and loop antennas, etc. A coil in a circuit refers to an inductor, which means that wires are wound one by one, and the wires are insulated from each other. The insulating tube can be hollow or can contain an iron core or a magnetic powder core, simply referred to as an inductor. In electronic components, a coil generally refers to a wire winding in a ring shape, and a cylindrical electronic coil is a common form among them. Currently, an automatic winding die for a cylindrical electronic coil usually consists of a cylindrical support tube and two side plates. Although it can wind the coil on the surface of the support tube, since the support tube is integrally formed and the coil is tightly wound on its surface, it is difficult to demold the coil in a short time.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1-7, An automatic winding die for an electronic coil, comprising a base 1, a motor 2 is installed on one side of the base 1, and rotating plates 3 are respectively rotatably connected to both sides of the inner wall of the base 1, and a support tube 4 is arranged between the rotating plates 3, and arc-shaped plates 5 are annularly arranged on the surface of the support tube 4; both ends of the support tube 4 are respectively provided with side plates 6, and a connecting tube 7 is connected to the center of the side plate 6, and moving grooves 8 are annularly and equidistantly opened on the surface of the connecting tube 7, a sleeve 9 is threadedly connected to the surface of the connecting tube 7, and a first sliding groove 10 is opened on the inner wall of the sleeve 9, three first sliders 11 are slidably connected inside the first sliding groove 10, and a connecting rod 12 which is movably connected to the inside of the moving groove 8 is connected to one side of the first slider 11, one end of the connecting rod 12 is connected to a first moving rod 13, and an extrusion block 14 is connected to one side of the first moving rod 13; annularly and equidistantly arranged mounting plates 15 are connected to the inner wall of the support tube 4, a moving plate 16 is slidably connected to the inner wall of the mounting plate 15, and a spring 17 is connected between the moving plate 16 and the mounting plate 15, a second moving rod 18 connected to the arc-shaped plate 5 is fixedly connected to the surface of the moving plate 16, and an extrusion ball 19 is connected to one end of the second moving rod 18. When demolding is required, by rotating the annular plate 25, the screw rod 28 can be removed from the inside of the rotating plate 3, so that the support tube 4 and the connecting tubes 7 on both sides can be removed from the base 1. By rotating the sleeve 9, since the sleeve 9 is threadedly connected to the connecting tube 7, the sleeve 9 can be rotated and moved. Since the first sliding groove 10 and the first slider 11 are arranged inside the sleeve 9, the sleeve 9 can drive the connecting rod 12 and the first moving rod 13 to move through the first sliding groove 10 and the first slider 11. The clamping block 23 on the first moving rod 13 on the right side can be first removed from the inside of the clamping groove 22, and then by rotating the sleeve 9 on the left side, the extrusion block 14 can be moved away from the surface of the extrusion ball 19. Through the action of the spring 17, the moving plate 16, the second moving rod 18 and the arc-shaped plate 5 can be driven to reset, and the arc-shaped plate 5 can be moved away from the inside of the coil, so that there is a certain distance between the coil and the arc-shaped plate 5, facilitating the demolding of the coil.

[0031] Further, the extrusion block 14 is frustum-shaped, and the surface of the extrusion block 14 is in contact with the surface of the extrusion ball 19. It is convenient that after the frustum-shaped extrusion block 14 is moved to the surface of the extrusion ball 19 and continuously moved and extruded, the extrusion ball 19 and the second moving rod 18 can be pushed to move.

[0032] Further, positioning holes 20 are annularly and equidistantly arranged at both ends of the support tube 4, and positioning rods 21 in contact with the positioning holes 20 are annularly and equidistantly arranged on one side of the side plate 6. It is convenient that after the positioning rod 21 is connected to the positioning hole 20, the side plate 6 can be restricted on one side of the support tube 4.

[0033] Further, a clamping groove 22 is formed on one side of the extrusion block 14, and a clamping block 23 connected to the clamping groove 22 is connected to one end of the first moving rod 13 on the other side. After the extrusion ball 19 is extruded by the extrusion block 14 on the left first moving rod 13, the clamping block 23 on the right first moving rod 13 can be moved again, and the clamping block 23 can be moved into the clamping groove 22 on the surface of the extrusion block 14, so that the side plates 6 on both sides can be installed at both ends of the support pipe 4.

[0034] Further, the other end of the connecting pipe 7 is connected with a backing plate 24, and an annular plate 25 is sleeved on the surface of the connecting pipe 7. A rack 26 is connected to the inner wall of the annular plate 25, and a gear 27 is connected to the surface of the rack 26. A screw rod 28 threadedly connected to the surface of the rotating plate 3 is connected to the center of the gear 27. By rotating the annular plate 25, the rack 26 can be moved on the surface of the gear 27, so as to drive the gear 27 and the screw rod 28 to rotate inside the backing plate 24. Since the screw rod 28 is threadedly connected to the backing plate 24, the screw rod 28 rotates on the surface of the second slider 30 and drives the annular plate 25 and the like to move, so as to facilitate passing the screw rod 28 through the backing plate 24 and connecting it to the inside of the rotating plate 3.

[0035] Further, a second sliding groove 29 is formed at the bottom end inside the annular plate 25, and a second slider 30 rotatably connected to the bottom end of the screw rod 28 is slidably connected inside the second sliding groove 29. When the annular plate 25 rotates, the second slider 30 can rotate on the surface of the screw rod 28 through the second sliding groove 29, so that the rack 26 on the inner wall of the annular plate 25 moves on the surface of the gear 27.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
