An anti-fraying automobile ignition coil winding device

Abstract

This invention relates to the field of automotive production equipment technology, specifically disclosing a wire breakage prevention device for automotive ignition coil winding. The device includes a mounting plate, a winding mechanism fixedly mounted on the mounting plate, and a stabilizing mechanism fixedly mounted on the winding mechanism. By setting both ends of the guide tube in a trumpet shape, the friction between the enameled copper wire and the openings at both ends of the guide tube is significantly reduced, thereby reducing the probability of wire breakage and improving winding stability. When the motor starts, it simultaneously drives the second drive shaft to rotate, which in turn drives the fixing clamp to move upwards along the central axis of the first and second mounting rings, while simultaneously rotating. This upward movement, combined with the rotating guide tube, significantly increases the winding speed of the ignition coil, thereby increasing the production speed of the ignition coil. Furthermore, the device operates with only one motor, improving its linkage performance and reducing production costs for the enterprise.

Description

Technical Field

[0001] This invention relates to the field of automotive production equipment technology, specifically to a winding device for preventing broken wires in automotive ignition coils. Background Technology

[0002] The ignition coil is a core component of a gasoline engine's ignition system. Its function is to convert the vehicle's low-voltage direct current into high-voltage electricity to ignite the air-fuel mixture in the cylinder by breaking down the spark plug gap. An ignition coil typically contains a primary winding, a secondary winding, and an iron core. The quality of the windings directly determines the voltage output characteristics and operational reliability of the ignition coil. During the manufacturing process of the ignition coil, the winding process is crucial; it involves using specialized winding equipment to evenly wind enameled copper wire onto a frame according to a predetermined number of turns and arrangement.

[0003] For example, application number "CN201810811066.7" discloses a winding device. The first mounting component of the waiting mechanism is correspondingly set with the clamping component of the fixing mechanism. The waiting mechanism can automatically feed the material to the fixing mechanism. After the fixing mechanism fixes the stator, the needle turning mechanism can automatically wind, guide, and wind the stator with the cooperation of the third, fourth, fifth, and sixth driving components. During the winding process, the second driving component drives the clamping component to move the stator in coordination, which can achieve precision wire arrangement. The winding device of the present invention can achieve efficient and high-quality winding. However, the existing automotive ignition coil winding devices still have the following shortcomings in practical applications: First, the openings at both ends of the guide tube of conventional winding devices are mostly right angles or sharp edges. When the enameled copper wire enters and exits the guide tube at high speed, it generates a large sliding friction force with the edge of the port. After long-term operation, the insulation layer on the surface of the enameled wire is easily scratched, which leads to wire breakage and seriously affects the continuity of winding operations and product qualification rate. Meanwhile, in existing equipment, the workpiece clamping mechanism typically remains stationary during the winding process, relying solely on the rotation or oscillation of the guide tube to complete the winding. This limits the winding speed and makes it difficult to meet the demands of high-efficiency production. Using multiple drive sources to separately control workpiece lifting and guide tube rotation increases equipment cost and control complexity, and the synchronization between actions is poor. Secondly, during winding, the fixed clamp only holds the ignition coil frame from the end. As the number of coils increases, the radial tension of the enameled copper wire on the frame gradually increases, easily causing the central axis of the fixed clamp to shift. This results in uneven subsequent winding arrangements, reducing the winding quality of the ignition coil. Furthermore, due to periodic tension fluctuations during winding, stress concentration easily occurs at the connection between the fixed clamp and the frame, further increasing the risk of wire breakage. Existing equipment generally lacks auxiliary support mechanisms for the fixed clamp, failing to dynamically enhance clamping stability during winding and effectively buffering sudden tension changes in the enameled wire. This leads to decreased equipment accuracy and increased scrap rate after prolonged use. In summary, how to reduce the probability of wire breakage while increasing winding speed, and ensure the long-term stability of workpiece clamping during the winding process, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a car ignition coil winding device for preventing wire breakage, comprising a mounting plate, and further comprising: a winding mechanism, the winding mechanism being fixedly mounted on the mounting plate; and a stabilizing mechanism, the stabilizing mechanism being fixedly mounted on the winding mechanism; wherein the winding mechanism comprises a first mounting ring, the first mounting ring being fixedly mounted on the outer surface of the mounting plate, a connecting rod being fixedly mounted through the upper surface of the first mounting ring, the connecting rod being fixedly spaced at three intervals around the central axis of the first mounting ring, and a second mounting ring being fixedly connected through the connecting rod, the second mounting ring being positioned directly below the first mounting ring.

[0006] According to one embodiment of the present invention, the inner surfaces of the first mounting ring and the second mounting ring are fixedly connected to mounting brackets, wherein the upper surfaces of the two mounting brackets are threaded through and connected to threaded rods, wherein the threaded rods are arranged with the first mounting ring and the second mounting ring on the same central axis.

[0007] According to one embodiment of the present invention, a mounting cover is fixedly connected to the bottom of the connecting rod, and a bearing plate is fixedly connected to the outer surface of the mounting cover. The outer surface of the first mounting ring is also fixedly connected to the bearing plate, and the first mounting ring and the bearing plate on the mounting cover are arranged with the same central axis. A motor is fixedly connected to the upper surface of the bearing plate on the mounting cover. The motor is configured as a dual-shaft drive, and the two ends of the motor are respectively rotatably connected to a first drive shaft and a second drive shaft.

[0008] According to one embodiment of the present invention, a drive wheel is fixedly connected to the outer surface of the first drive shaft, a slider is slidably connected to the inner surface of the mounting cover, a rotating ring is fixedly connected to the bottom surface of the slider, and the upper surface of the rotating ring is rotatably connected to the lower surface of the mounting cover, wherein the outer surface of the mounting cover is rotatably connected to the outer surface of the drive wheel.

[0009] According to one embodiment of the present invention, a connecting frame is fixedly connected to the bottom surface of the rotating ring, and a conduit is fixedly connected through the connecting frame, the two ends of the conduit being flared.

[0010] According to one embodiment of the present invention, the top of the second drive shaft is rotatably connected to the upper surface of the bearing plate on the first mounting ring, wherein a transmission belt is rotatably connected to the top outer surface of the second drive shaft, and sliding grooves are symmetrically opened on both outer surfaces of the threaded rod, wherein a limiting ring is slidably connected to the outer surface of the threaded rod through the sliding groove, the bottom surface of the limiting ring is rotatably connected to the upper surface of the mounting bracket, and the end of the transmission belt away from the second drive shaft is rotatably connected to the outer surface of the limiting ring.

[0011] According to one embodiment of the present invention, a fixing clip is fixedly connected to the bottom of the threaded rod, and the bottom of the fixing clip is initially set to the same horizontal plane as the mounting cover.

[0012] According to one embodiment of the present invention, the stabilizing mechanism includes a stabilizing frame, the outer end of which is slidably connected to the outer surface of the connecting rod, the lower middle surface of which is rotatably connected to the upper surface of the fixing clamp, and the stabilizing frame is not connected to the threaded rod.

[0013] According to one embodiment of the present invention, a compression bladder is fixedly connected to the upper surface of the outer end of the stabilizer, the compression bladder is sleeved on the outside of the connecting rod, wherein the top of the compression bladder is fixedly connected to the lower surface of the second mounting ring, and elastic telescopic rods are symmetrically fixedly connected to the outer surfaces of the two sides of the fixing clamp, the internal cavity of the elastic telescopic rod is in communication with the internal cavity of the compression bladder, and a compression plate is fixedly connected to the output end of the elastic telescopic rod, the compression plate and the outer surface of the fixing clamp being arranged parallel to each other.

[0014] When it is necessary to wind the car ignition coil, first fix the device with the mounting plate, then fix the top of the ignition coil with the fixing clip, then pass the enameled copper wire through the conduit and connect it to the top of the ignition coil, and then start the motor. As the motor starts, it will drive the first drive shaft to rotate, which will drive the drive wheel to rotate, and then drive the rotating ring to start rotating relative to the mounting cover. That is, the conduit at the bottom of the mounting ring will start to rotate along the ignition coil. At this time, the enameled copper wire will be wound around the outer surface of the ignition coil, and finally the winding operation is completed.

[0015] (III) Beneficial Effects This invention provides a winding device for preventing broken wires in automotive ignition coils. It has the following beneficial effects: (I) This anti-breakage automotive ignition coil winding equipment significantly reduces the friction between the enameled copper wire and the openings at both ends of the conduit by setting the two ends of the conduit in a trumpet shape, thereby reducing the probability of wire breakage and improving winding stability. After the motor starts, it will simultaneously drive the second drive shaft to rotate. As the second drive shaft rotates, it will drive the transmission belt to rotate, which in turn will drive the limit ring to rotate, and finally drive the threaded rod to rotate. The threaded rod is connected to the middle of the mounting bracket on the first and second mounting rings by threads. As the threaded rod rotates, it will move upwards, thereby driving the fixing clamp to move upwards along the central axis of the first and second mounting rings. During the upward movement, it will rotate synchronously. In conjunction with the rotating conduit, the winding speed of the ignition coil is greatly improved, thereby increasing the production speed of the ignition coil. At the same time, the entire equipment can be driven by a single motor, which not only improves the linkage performance of the equipment, but also reduces the production cost of the enterprise.

[0016] (II) In this anti-breakage automotive ignition coil winding device, when the fixed clamp moves upward, it simultaneously drives the stabilizer to move upward. It is known that the outer end of the stabilizer is slidably connected to the connecting rod, meaning that the stabilizer will not rotate when it moves upward. This causes the compression bladder to begin to compress, resulting in an increasing air pressure inside the compression bladder. This air pressure is then transmitted to the interior of the elastic telescopic rod, causing the air pressure inside the elastic telescopic rod to rise. This pushes the compression plate towards one side of the fixed clamp, eventually compressing both sides of the fixed clamp. This gradually supports both sides of the fixed clamp during winding, preventing the positioning clamp from shifting its central axis and reducing the winding quality due to the tension of the enameled copper wire after prolonged use. It also prevents the enameled copper wire from breaking due to periodic tension changes during winding, further improving the working stability of this device. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] First embodiment: as follows Figures 1 to 8 As shown, the present invention provides a technical solution: a car ignition coil winding device to prevent wire breakage, including a mounting plate 1, and further comprising: Winding mechanism 2 is fixedly mounted on mounting plate 1; Stabilizing mechanism 3 is fixedly installed on winding mechanism 2; The winding mechanism 2 includes a first mounting ring 21, which is fixedly mounted on the outer surface of the mounting plate 1. A connecting rod 22 is fixedly mounted through the upper surface of the first mounting ring 21. The connecting rod 22 is arranged at fixed intervals around the central axis of the first mounting ring 21.

[0022] A mounting cover 26 is fixedly connected to the bottom of the connecting rod 22. A bearing plate 27 is fixedly connected to the outer surface of the mounting cover 26.

The first mounting ring 21 and the bearing plate 27 on the mounting cover 26 are arranged on the same central axis. A motor 28 is fixedly connected to the upper surface of the bearing plate 27 on the mounting cover 26. The motor 28 is configured as a dual-shaft drive. The two ends of the motor 28 are respectively rotatably connected to the first drive shaft 29 and the second drive shaft 210.

[0023] A drive wheel 211 is fixedly connected to the outer surface of the first drive shaft 29. A slider 212 is slidably connected to the inner surface of the mounting cover 26. A rotating ring 213 is fixedly connected to the bottom surface of the slider 212. The upper surface of the rotating ring 213 is rotatably connected to the lower surface of the mounting cover 26. The outer surface of the mounting cover 26 is rotatably connected to the outer surface of the drive wheel 211.

[0024] A connecting frame 214 is fixedly connected to the bottom surface of the rotating ring 213, and a conduit 215 is fixedly connected through the connecting frame 214. The two ends of the conduit 215 are flared.

[0025] The top of the second drive shaft 210 is rotatably connected to the upper surface of the bearing plate 27 on the first mounting ring 21. A transmission belt 216 is rotatably connected to the top outer surface of the second drive shaft 210. Sliding grooves 217 are symmetrically opened on both outer surfaces of the threaded rod 25. A limit ring 218 is slidably connected to the outer surface of the threaded rod 25 through the sliding grooves 217. The bottom surface of the limit ring 218 is rotatably connected to the upper surface of the mounting bracket 24. The end of the transmission belt 216 away from the second drive shaft 210 is rotatably connected to the outer surface of the limit ring 218.

[0026] The bottom of the threaded rod 25 is fixedly connected to a fixing clip 219, and the bottom of the fixing clip 219 is initially set to the same horizontal plane as the mounting cover 26.

[0027] Second embodiment: as follows Figures 1 to 8 As shown, the stabilizing mechanism 3 includes a stabilizing frame 31. The outer end of the stabilizing frame 31 is slidably connected to the outer surface of the connecting rod 22. The lower middle surface of the stabilizing frame 31 is rotatably connected to the upper surface of the fixing clamp 219. The stabilizing frame 31 is not connected to the threaded rod 25.

[0028] A compression bladder 32 is fixedly connected to the upper surface of the outer end of the stabilizer 31. The compression bladder 32 is sleeved on the outside of the connecting rod 22. The top of the compression bladder 32 is fixedly connected to the lower surface of the second mounting ring 23. Elastic telescopic rods 33 are symmetrically fixedly connected to the outer surfaces of the two sides of the fixing clamp 219. The internal cavity of the elastic telescopic rod 33 communicates with the internal cavity of the compression bladder 32. A compression plate 34 is fixedly connected to the output end of the elastic telescopic rod 33. The compression plate 34 and the outer surface of the fixing clamp 219 are arranged parallel to each other.

[0029] During operation, when it is necessary to wind the automotive ignition coil, the device is first fixed by mounting plate 1. Then, the top of the ignition coil is positioned and fixed by fixing clip 219. Next, the enameled copper wire is passed through the conduit 215 and connected to the top of the ignition coil. Then, the motor 28 is started. As the motor 28 starts, it drives the first drive shaft 29 to rotate, which in turn drives the drive wheel 211 to rotate, which in turn drives the rotating ring 213 to start rotating relative to the mounting cover 26. That is, the conduit 215 at the bottom of the mounting ring starts to rotate along the ignition coil. At this time, the enameled copper wire will be wound around the outer surface of the ignition coil, and the winding operation is finally completed. The two ends of 215 are flared, which significantly reduces the friction between the enameled copper wire and the openings at both ends of the conduit 215, thereby reducing the probability of wire breakage and improving winding stability. When the motor 28 starts, it simultaneously drives the second drive shaft 210 to rotate. The rotation of the second drive shaft 210 drives the transmission belt 216 to rotate, which in turn drives the limit ring 218 to rotate, ultimately causing the threaded rod 25 to rotate. The threaded rod 25 is threadedly connected to the middle of the mounting brackets 24 on the first mounting ring 21 and the second mounting ring 23, respectively. Therefore, as the threaded rod 25 rotates, it moves upwards simultaneously. The movement of the fixed clamp 219, along with the central axis of the first mounting ring 21 and the second mounting ring 23, causes the fixed clamp 219 to move upwards. Simultaneously, the fixed clamp 219 rotates during this upward movement. This, combined with the rotating guide tube 215, significantly increases the winding speed of the ignition coil, thereby increasing the production speed of the ignition coil. Furthermore, the entire equipment can be driven by a single motor 28, improving the linkage performance of the equipment and reducing production costs. The upward movement of the fixed clamp 219 also causes the stabilizer 31 to move upwards. It is known that the outer end of the stabilizer 31 is slidably connected to the connecting rod 22, meaning that the stabilizer 31 does not rotate during upward movement, thus initiating the compression process. The compression bladder 32 is squeezed, causing the air pressure inside the bladder 32 to increase. This air pressure is then transmitted to the interior of the elastic telescopic rod 33, increasing the air pressure inside the rod. This causes the compression plate 34 to move towards the fixed clamp 219, eventually compressing both sides of the fixed clamp 219. This gradually supports both sides of the fixed clamp 219 during winding, preventing the positioning clamp from shifting its central axis due to the tension of the enameled copper wire after prolonged use, thus reducing the winding quality. It also prevents the enameled copper wire from breaking due to periodic tension changes during winding, further improving the working stability of the equipment.
