Description

Technical Field

[0001] This application relates to the field of hollow coil manufacturing technology, and in particular to a hollow coil winding device. Background Technology

[0002] An air-core coil is an AC current sensor, consisting of a hollow ring-shaped coil available in both flexible and rigid forms. It can be directly wrapped around the conductor being measured to measure AC current. Air-core coils are suitable for measuring AC current over a wide frequency range, have no special requirements for conductor or size, and possess a fast instantaneous response capability. They are widely used in situations where traditional current measuring devices, such as current transformers, cannot be used, for current measurement, especially high-frequency, high-current measurements. The production of air-core coils requires the use of appropriate winding devices.

[0003] Currently, Chinese utility model patent application CN219832408U, published on October 13, 2023, discloses a hollow coil winding machine, including a worktable, support legs, a moving structure, a winding structure, a guide structure, and a limiting plate. The worktable has support legs at its bottom, the moving structure is located at the top of the worktable, the winding structure is located within the moving structure, the guide structure is located at one end of the top of the worktable, and the limiting plate is located within the winding structure. This utility model's limiting plate is an assemblable limiting plate, fixed to the baffles at both ends of the first and second winding columns via a fixing structure and a rotating structure, facilitating the fixation of hollow coils of different sizes on both sides during winding.

[0004] One type of hollow coil winding machine in the related technology uses only one guide ring to control the position of the wire during winding. There is a gap between the wire and the guide ring, which may cause the position of the wire to shift during movement, thus reducing the winding quality. Utility Model Content

[0005] This application provides a hollow coil winding device, which can improve the technical problem that the position of the conductor may shift during winding in related technologies.

[0006] This application provides a hollow coil winding device, including: a base, a feeding mechanism, a limiting mechanism, and a winding mechanism. The feeding mechanism includes a transmission table, a limiting ring, a wire-stopping frame, and a power component. The power component, the feeding mechanism, and the winding mechanism are all mounted on the base. The transmission table is mounted on the power component, which controls the position of the base. The wire-stopping frame has a wire-stopping groove. The wire-stopping frame and the limiting ring are both mounted on the transmission table.

[0007] The technical solution described above in this application embodiment has at least the following technical effects: Before the device is in operation, the operator can pull out the wire from the feeding mechanism and pass the wire through the inside of the limiting ring. Then, the wire is pressed into the abutment groove and connected to the winding mechanism. When the device is in operation, the winding mechanism pulls the wire to move. The limiting ring restricts the wire in contact with it inside. The abutment frame presses against the wire inside the abutment groove to make the wire taut and keep it close to the abutment groove as it continues to move toward the winding mechanism, which can prevent the wire position from shifting. At this time, the power component can accurately control the position of the wire by controlling the position of the transmission table, thereby improving the winding quality.

[0008] The hollow coil winding device provided in this application embodiment can more accurately control the position of the wire during winding by cooperating with the limiting ring and the wire abutment frame, thereby improving the quality of the finished hollow coil.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0026] Based on this, in order to improve the problem that the position of the conductor may shift during winding in related technologies, the embodiments of this application provide the following solution.

[0027] Please refer to the following: Figures 1 to 6 This application provides a hollow coil winding device, which includes a base 1, a feeding mechanism 2, a limiting mechanism, and a winding mechanism.

[0028] Please refer to the following: Figures 1 to 6The limiting mechanism includes a transmission table 31, a limiting ring 32, a wire-stopping frame 33, and a power assembly. The power assembly, the feeding mechanism 2, and the winding mechanism are all mounted on the base 1. The power assembly includes a stepper motor 341, a lead screw 342, a first optical shaft 343, and a first support plate 344. The stepper motor 341 and the first support plate 344 are both mounted on the base 1. The two ends of the first optical shaft 343 are fixedly connected to the first support plate 344. The two ends of the lead screw 342 are rotatably connected to the first support plate 344. The output shaft of the stepper motor 341 passes through the first support plate 344. 44 is connected to the lead screw 342 for transmission. The transmission table 31 is slidably connected to the first optical shaft 343. The lead screw 342 passes through the transmission table 31 and is threadedly connected to the transmission table 31. The wire abutment frame 33 is provided with a wire abutment groove 331. The wire abutment frame 33 and the limiting ring 32 are both provided on the transmission table 31. The feeding mechanism 2 includes a second support plate 21, a first rotating shaft 22 and a wire coil 23. The second support plate 21 is provided with an installation port 211. The two ends of the first rotating shaft 22 are rotatably connected to the installation port 211. The wire coil 23 is sleeved on the first rotating shaft 22. The winding mechanism includes The control assembly, transmission frame 42, motor 43, winding shaft 44, pressing table 45, second rotating shaft 46, and third support plate 47 are all mounted on the base 1. The control assembly includes an electric push cylinder 411, a second optical shaft 412, a limit slider 413, and a fourth support plate 414. The electric push cylinder 411 and the fourth support plate 414 are both mounted on the base 1. One end of the second optical shaft 412 is fixedly connected to the fourth support plate 414, and the other end of the second optical shaft 412 is fixedly connected to the base 1. The limit slider 413 is slidably connected to the second support plate 414. On the optical axis 412, the transmission frame 42 is fixedly connected to the top of the limit slider 413. The output shaft of the electric push cylinder 411 is connected to the transmission frame 42. The motor 43 is mounted on the transmission frame 42. The output shaft of the motor 43 passes through the transmission frame 42. The winding shaft 44 is keyed to the output shaft of the motor 43. A rubber pad 441 is provided at the end of the winding shaft 44 away from the motor 43. One end of the second rotating shaft 46 is rotatably connected to the third support plate 47. The pressing table 45 is fixedly connected to the end of the second rotating shaft 46 away from the third support plate 47. A baffle line 12 is also provided on the base 1.

[0029] As can be seen from the above, the hollow coil winding device provided in this application embodiment allows the operator to pull the wire from the wire coil 23 and pass it through the inside of the limiting ring 32 before operation. The wire is then pressed into the abutment groove 331, and the wire end is pulled to press it against the groove on the pressure plate 471. At this time, the wire located between the abutment frame 33 and the pressure plate 471 is precisely against the pressure table 45. Then, the device is started, and the electric pusher cylinder 411 pushes the transmission frame 42 and the motor 43 towards the pressure table 45. The transmission frame 42 drives the limiting slider 413 to slide on the second optical axis 412. The winding shaft 44 moves towards the pressure table 45 under the push of the output shaft of the motor 43 until it reaches the edge of the rubber pad 441. Partially pressing the wire onto the pressing table 45, the portion of the rubber pad 441 not in contact with the wire is also pressed onto the pressing table 45. Then, the operator can loosen the wire. The output shaft of the motor 43 drives the winding shaft 44 to rotate. The winding shaft 44, through the friction between the rubber pad 441 and the pressing table 45, drives the pressing table 45 and the second rotating shaft 46 to rotate. Because the wire is pressed onto the pressing table 45 by the rubber pad 441, it is also pulled and begins to be wound onto the winding shaft 44. At this time, the output shaft of the stepper motor 341 drives the lead screw 342 to rotate, thereby driving the transmission table 31 to move on the first optical axis 343. The limiting ring 32 confines the wire inside, and the wire abutment frame 33 presses against the wire inside the wire abutment groove 331, making the wire taut. The wire continues to move towards the winding post while remaining close to the abutment groove 331. The stepper motor 341 can precisely control the relative position between the wire and the winding shaft 44 by controlling the positions of the transmission table 31 and the abutment frame 33. The wire pulls the wire coil 23 to rotate, which in turn drives the first rotating shaft 22 to rotate inside the mounting port 211, continuously feeding wire onto the winding shaft 44. As the winding shaft 44 winds the wire, the abutment frame 33 continuously moves to a preset position, preventing the wire position from shifting during winding and reducing the quality of the finished coil. After winding is complete, the operator can use tools to cut the wire between the winding shaft 44 and the abutment frame 33, and then control the electric pusher cylinder 411 to move the winding shaft 44 away from the pressure table 45 to return to its initial position. During this process, the coil on the winding spool 44 will touch the stop line 12, which will block the movement of the coil, thus causing the coil to detach from the winding spool 44. Then, the operator can remove the detached coil, and the stepper motor 341 will drive the transmission table 31 back to the initial position. After the transmission table 31 and the winding spool 44 have returned to the initial position, the operator can repeat the above process to continuously produce coils. When the wire on the wire roll 23 is used up, the operator can remove the empty wire roll 23 and the first rotating shaft 22 from the second support plate 21, then put the new wire roll 23 on the first rotating shaft 22, and then install the first rotating shaft 22 back into the mounting port 211 to continue working, which can ensure that the device can work for a long time.

[0030] In some embodiments, please refer to the following: Figure 2 and Figure 4 The third support plate 47 is provided with a pressure plate 471 and a grating door output end 472, and the base 1 is provided with a grating door receiver end 11.

[0031] With this configuration, the output end 472 of the grating gate will send a light signal to a specific position of the receiver end 11 of the grating gate. When a foreign object or a worker's arm blocks the light signal, the receiver end 11 of the grating gate will send a signal to stop the operation of each power source of the device, so as to prevent the worker from being accidentally injured by the device due to operational errors and reduce safety hazards during production.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
