Abstract
Description
Technical Field
[0001] This invention relates to the field of coil winding technology, and more specifically to a winding device for automotive ignition coils. Background Technology
[0002] An ignition coil typically consists of a frame and wires wound around it. Currently, most methods involve workers using winding tools to wrap the wires around the frame layer by layer to ensure the coil's neatness and uniformity. However, this winding process is labor-intensive, lacks integration, and is inefficient.
[0003] To address the aforementioned issues, an automatic winding device has been commercially available. This device includes a winding box, a motor, a rotating shaft, a coil drum, a wire box, and several spools. The motor is fixedly connected to the inner wall of the winding box; the rotating shaft is fixedly connected to the motor's output shaft; the coil drum is fixedly connected to the rotating shaft; and the spools are all fixedly connected to the inner wall of the wire box, with adjacent spools staggered vertically along the length of the wire box. In use, the wire inside the coil is sequentially threaded onto two adjacent spools, then connected to the coil drum. Finally, the rotation of the coil drum automatically winds the wire around it, thus improving the efficiency and quality of the wire winding process.
[0004] The above-mentioned device has the following problems in actual use: When the wire is wound, the wire is relatively soft and cannot be straightened. If the wire is not straightened and is wound directly, it is easy for the wire to get knotted, which will damage the quality of the coil formed by the wire winding and make it unable to work efficiently. Summary of the Invention
[0005] This invention provides a winding device for automotive ignition coils to solve the problem that existing winding devices cannot straighten the wires during the winding process.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a winding device for automotive ignition coils, comprising an operating box, a rotating shaft, a coil cylinder, and a drive mechanism for driving the rotating shaft to rotate. The rotating shaft is rotatably connected to the inner wall of the operating box, and the coil cylinder is fixedly connected to the rotating shaft. It also includes a processing mechanism disposed within the operating box. The processing mechanism includes a guide tube, a processing box with through holes on both sides, and processing components disposed on both sides of the guide tube along its length. Both sides of the guide tube are connected to two through holes. The processing box is fixedly connected to the operating box. The processing components include a guide cylinder, a guide block, a fixed block, a side block, a clamping arm block, a side hole on the guide tube, a drive unit for driving the guide block to reciprocate along the length of the guide cylinder, and a power unit for driving the side block to reciprocate along the width of the fixed block. The guide cylinder is fixedly connected to the operating box. The guide block is slidably connected to the guide cylinder. The fixed block is fixedly connected to the guide block. The side block is slidably connected to the fixed block, and the free end of the side block extends into the side hole. The clamping arm block is connected to the free end of the side block. The two guide blocks move in opposite directions.
[0007] The principles and advantages of this scheme are: The wire is passed through the through-hole from one end of the conduit to the other end and connected to the coil drum. As the coil drum rotates, the wire gradually winds around it. During the wire's movement within the conduit, two clamping arms hold the wire from both sides, thus reducing the probability of knotting and improving the efficiency and quality of the winding process.
[0008] The two clamping arms are positioned in opposite directions to expand the range of action on the conductor, thereby increasing the conductor's tension and enhancing its effectiveness.
[0009] During the reciprocating motion of the clamping arm block, the continuous squeezing by the side blocks improves the fit between the clamping arm block and the wire, thereby enhancing the force exerted by the clamping arm block on the wire and ensuring that the clamping arm block can clamp the wire more efficiently, thus enabling the wire to be taut more fully.
[0010] Furthermore, the processing component also includes a linkage unit; the linkage unit further includes a guide rod, a nut seat, a linkage block, a first spring, a clamping groove in the clamping arm block, a linkage hole in the guide tube, and a linkage unit for driving the nut seat to reciprocate; the guide rod is fixedly connected to the fixed block; the nut seat is slidably connected to the guide rod; the linkage block is fixedly connected to the nut seat, the linkage block extends into the linkage hole, and the linkage block abuts against the clamping arm block; the side block is slidably connected to the clamping groove, and the two ends of the first spring are respectively connected to the side block and the clamping groove.
[0011] Through the combined action of the linkage block and the first spring, the clamping arm block can perform vertical reciprocating motion relative to the side block, thus placing the clamping arm block in a dynamic clamping state. Therefore, under the dynamic clamping of the clamping arm block, the clamping arm block can make fine adjustments to the wire at any time, thereby further improving the stability of the wire clamping and reducing the probability of the wire getting tangled.
[0012] Furthermore, the processing assembly also includes an auxiliary section; the auxiliary section includes an auxiliary rod, several auxiliary brushes, a side groove on the clamping arm block, and an auxiliary unit for driving the auxiliary rod to perform vertical reciprocating motion; the auxiliary rod is slidably connected to the clamping arm block and extends into the side groove; the several auxiliary brushes are all fixedly connected to the auxiliary rod.
[0013] During the clamping of the wire by the clamping arm block, the auxiliary rod drives the auxiliary brush to make vertical reciprocating motion, thereby sweeping away foreign objects adhering to the wire, reducing the interference of foreign objects on the ignition coil, and thus improving the working quality of the ignition coil.
[0014] Furthermore, the processing mechanism also includes a cleaning component; the cleaning component includes an annular hollow block, an inner block with cleaning holes, several scrapers arranged along the circumferential direction of the annular hollow block, and a moving part for driving the annular hollow block to rotate; the inner block is fixedly connected to the inner wall of the conduit; the annular hollow block is rotatably connected to the inner block; and the scrapers are fixedly connected to the inner wall of the annular hollow block.
[0015] During the winding of the wire, the rotation of the scraper allows for thorough and comprehensive cleaning of foreign objects with strong adhesion to the wire, thereby reducing the amount of foreign objects adhering to the wire and ensuring that the ignition coil can work more efficiently.
[0016] The scraper can also catch knotted wires, prompting workers to intervene manually to prevent the knotted wires from getting tangled on the coil drum.

[0018] The guide wheel is designed to move the wire toward the location of the coil drum and to initially position the wire. Then, in conjunction with the clamping arm block, the wire is straightened, thereby comprehensively enhancing the clamping effect of the clamping arm block on the wire.

[0020] The push wheel is designed to expand the range of the push on the conductor, allowing it to be pushed from multiple points, thus enabling the conductor to move more efficiently toward the location of the coil drum.

[0022] During the reciprocating motion of the side block along the length of the wall block, the combined action of the power block, the second spring, and the semi-circular groove causes the side block to drive the clamping arm block to continuously squeeze the wire.
[0023] Furthermore, the linkage unit includes a screw, a linkage component for driving the screw to rotate; the screw is rotatably connected to the fixed block; and the nut seat is threadedly connected to the screw.
[0024] During screw rotation, the nut seat can reciprocate along the axial direction of the screw.

[0054] Specific implementation process: The wire is passed through the through hole from one end of the conduit 4 to the other end and connected to the coil drum 3. Then, the first motor is started, and the output shaft of the first motor drives the rotating shaft 2. During the rotation of the rotating shaft 2, the coil drum 3 rotates synchronously, and the wire is gradually wound around the coil drum 3. During the movement of the wire inside the conduit 4, it is clamped from both sides by two clamping arms 10, which can pull the wire and reduce the probability of the wire getting tangled, thereby improving the efficiency and quality of the wire winding.
[0055] During the winding of the wire, the second motor 33 is started, and the output shaft of the second motor 33 drives the guide shaft 19 to rotate. During the rotation of the guide shaft 19, the second cam 41 rotates synchronously. When the protrusion of the second cam 41 abuts against the guide block 7, the guide block 7 moves closer to the inner wall of the guide cylinder 6, and the fifth spring is compressed. When the protrusion of the second cam 41 no longer abuts against the guide block 7, the guide block 7 returns to its original position under the action of the fifth spring, and moves away from the inner wall of the guide cylinder 6. Therefore, the guide block 7 can perform reciprocating motion. Furthermore, since the protrusions of the two second cams 41 face opposite directions, the two guide blocks 7 move in opposite directions.
[0056] During the movement of guide block 7, guide block 7 drives clamping arm block 10 to move via fixing block 8. The two clamping arm blocks 10 are arranged in opposite directions to expand the range of action on the conductor, thereby enabling the conductor to be stretched more taut, which further enhances the effect on the conductor.
[0057] During the reciprocating motion of the side block 9 along the length of the wall block 23, the combined action of the power block 24, the second spring 25, and the semi-circular groove causes the side block 9 to drive the clamping arm block 10 to continuously squeeze the wire.
[0058] During the reciprocating motion of the clamping arm block 10, the side block 9 continuously squeezes, thereby improving the fit between the clamping arm block 10 and the wire, thus enhancing the force exerted by the clamping arm block 10 on the wire, ensuring that the clamping arm block 10 can clamp the wire more efficiently, that is, enabling the wire to be taut more fully.
[0059] During the movement of the fixed block 8, the first gear 32 engages sequentially with the first incomplete rack 37 and the second incomplete rack 38, thereby driving the screw 26 to perform forward and reverse movements. During the rotation of the screw 26, the nut seat 14 drives the linkage block 15 to perform vertical reciprocating movements.
[0060] During the vertical reciprocating motion of the linkage block 15, the clamping arm block 10 can reciprocate vertically relative to the side block 9 under the combined action of the linkage block 15 and the first spring, thus placing the clamping arm block 10 in a dynamic clamping state. Therefore, under the dynamic clamping of the clamping arm block 10, the clamping arm block 10 can make fine adjustments to the wire at any time, thereby further improving the stability of the wire clamping, that is, reducing the probability of the wire getting tangled.
[0061] During the rotation of the guide shaft 19, the guide shaft 19 drives the worm gear to rotate via the belt 40. During the rotation of the worm gear, the first cam 39 rotates synchronously. During the rotation of the first cam 39, when the protrusion of the first cam 39 abuts against the drive block 29, the drive block 29 moves vertically downward, and the fourth spring is compressed; when the protrusion of the first cam 39 no longer abuts against the drive block 29, the drive block 29 returns to its original position under the action of the fourth spring, and the drive block 29 moves vertically upward. Therefore, the drive block 29 can perform vertical reciprocating motion. During the movement of the drive block 29, the pressure rod 30 moves synchronously.
[0062] During the movement of the pressure rod 30, the auxiliary rod 16, under the combined action of the pressure rod 30 and the third spring, can perform vertical reciprocating motion. Therefore, while the clamping arm block 10 is clamping the wire, the auxiliary rod 16 drives the auxiliary brush to perform vertical reciprocating motion, thereby removing foreign objects adhering to the wire, reducing interference from foreign objects on the ignition coil, and thus improving the working quality of the ignition coil.
[0063] During the rotation of the worm gear, the first gear 32 rotates synchronously. During the rotation of the first gear 32, the meshing of the first gear 32 with the annular rack causes the annular rack to drive the scraper to rotate. Therefore, during the wire winding process, the rotation of the scraper allows for thorough and comprehensive cleaning of foreign objects with strong adhesion to the wire, further reducing the amount of foreign objects adhering to the wire and ensuring that the ignition coil can operate more efficiently.
[0064] The scraper can also catch knotted wires, prompting workers to intervene manually to prevent the knotted wires from getting tangled on the coil drum 3.
[0065] During the rotation of the guide shaft 19, the guide wheel 20 rotates synchronously. The guide wheel 20 is designed to enable the wire to move towards the position of the coil drum 3 and to initially position the wire, thereby working with the clamping arm block 10 to straighten the wire and comprehensively enhance the clamping effect of the clamping arm block 10 on the wire.
[0066] During the rotation of the worm, the top shaft 21 rotates due to the meshing of the worm wheel 34 with the worm. During the rotation of the top shaft 21, the drive wheel 22 rotates synchronously. The drive wheel 22 is designed to expand the range of the conductor's movement, allowing the conductor to be driven from multiple points, thereby enabling the conductor to move more efficiently towards the location of the coil cylinder 3.
[0067] In summary, by straightening the wire, removing foreign objects from the wire, and causing the wire to move towards the position of the coil cylinder 3, the variety of wire winding effects is enriched, thus comprehensively improving the efficiency and quality of wire winding.
