Description

Technical Field

[0001] This utility model relates to the field of inductor coil technology, specifically a coil tightening mechanism. Background Technology

[0002] An inductor is a device that works using the principle of electromagnetic induction. When current flows through a wire, a certain electromagnetic field is generated around the wire, and the wire itself will induce an effect on other wires within the range of this electromagnetic field.

[0003] In the process of processing inductor coils, copper wire needs to be wound around the coil body. Currently, some manufacturers still rely on manual operation for winding the copper wire. During manual winding, it is impossible to apply the same tightening force to each turn of copper wire, which reduces the stability of coil processing. Therefore, a coil tightening mechanism is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A coil tightening mechanism of this utility model includes a base, a first motor fixedly connected to the outer side of the base, a first gear fixedly connected to the output end of the first motor, a second gear meshing with the outer side of the first gear, a winding roller fixedly connected to the outer side of the second gear, a support block rotatably connected to the outer side of the first gear, a rod slidably connected to the outer side of the support block, a slot formed on the surface of the first gear, the slot and the rod working together, a clamping screw rotatably connected to the inner side of the support block, a clamping plate threadedly connected to the outer side of the clamping screw, the clamping plate and the support block slidably connected, a fixing block fixedly connected to the outer side of the base, a second motor fixedly connected to the outer side of the fixing block, a third gear fixedly connected to the output end of the second motor, a lifting screw rotatably connected to the outer side of the fixing block, a lifting plate threadedly connected to the outer side of the lifting screw, and both the lifting plate and the inner side of the fixing block rotatably connected. A semi-circular plate is attached, with a fixing strip fixedly connected to the inner side of one side of the semi-circular plate and a semi-gear ring fixedly connected to the outer side of the semi-circular plate. The semi-gear ring and the third gear work together. In this step, by setting up the first gear, the take-up roller, the semi-circular plate, and the semi-gear ring, the copper wire is first tightly wound around the outer side of the take-up roller, then one end is pulled out and wound around the outer side of the fixing strip. Then the lifting plate is lowered, placing one side of the coil between the clamping plate and the support block, and the other side between the semi-circular plates. Then the semi-circular plate is returned to its position, and the second motor drives the semi-gear ring to rotate, so that the semi-circular plate drives one end of the copper wire to start rotating around the coil. At the same time, the first motor drives the coil and the take-up roller to rotate in opposite directions, so that the take-up roller can stably tighten the copper wire. Thus, when the copper wire moves, a uniform tension force is applied to it, and through the rotation of the coil, the copper wire can be evenly wound around the outer side of the coil. Therefore, during winding, the copper wire can be evenly tightened and wound, making the coil production more stable and improving the stability of the device.

[0006] Preferably, a spring is fixedly connected to the outside of the fixing block, and a push plate is fixedly connected to one end of the spring. The push plate and the fixing block are slidably connected. By setting the spring and the push plate, when the copper wire is wound, the spring pushes the push plate to stick to the coil, thereby limiting and blocking the copper wire wound by the device, making it less likely to be excessively dispersed during winding, and improving the stability of the device.

[0007] Preferably, a fixing plate is slidably connected to the inner side of the fixing block, and the fixing plate and the push plate are used in conjunction. By setting the fixing plate, when the push plate is not needed, the fixing plate can be pulled out from the inner side of the fixing block to block the lower side of the push plate, making it difficult for the push plate to move down and improving the stability of the device.

[0008] Preferably, a guide plate is fixedly connected to the outer side of the base, and an elastic pad is fixedly connected to the outer side of the guide plate. This step, by setting the guide plate, shields the copper wire when the winding roller releases it, making it less likely to come into contact with the coil during unwinding and cause wear, thus further improving the stability of the device.

[0009] Preferably, a limiting plate is threadedly connected to the outer side of the take-up roller, and the limiting plate and the semi-circular plate are used in conjunction. This step, by setting the limiting plate and screwing it onto the outer side of the take-up roller, further restricts the position of the copper wire when the take-up roller unwinds the copper wire, thereby improving the stability of the device operation.

[0010] Preferably, a friction pad and a suction cup are fixedly connected to the outer side of the base. This step, by setting the friction pad and the suction cup, makes it easy for the device to be adsorbed onto the installation site by the suction cup, and the friction pad is used to increase the friction coefficient between the device and the installation site, thereby facilitating the placement and installation of the device and improving the convenience of using the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a first gear, a take-up roller, a semi-circular plate, and a semi-gear ring, first tightly winds the copper wire around the outside of the take-up roller, then pulls out one end and winds it around the outside of the fixing strip, then lowers the lifting plate, placing one side of the coil between the clamping plate and the support block, and the other side between the semi-circular plates, and then returns the semi-circular plates to their original position. The second motor drives the semi-gear ring to rotate, so that the semi-circular plate drives one end of the copper wire to start rotating around the coil. At the same time, the first motor drives the coil and the take-up roller to rotate in opposite directions, so that the take-up roller can stably tighten the copper wire. Thus, when the copper wire moves, a uniform tension force is applied to it, and through the rotation of the coil, the copper wire can be evenly wound around the outside of the coil. Therefore, during winding, the copper wire can be evenly tightened and wound, making the production of the coil more stable and improving the stability of the device.

[0013] 2. By setting a spring and a push plate, the copper wire is wound and the spring pushes the push plate to stick to the coil, thereby limiting and blocking the copper wire being wound, making it less likely to be excessively dispersed during winding, and improving the stability of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown, a coil tightening mechanism includes a base 1. A first motor 2 is fixedly connected to the outer side of the base 1. A first gear 3 is fixedly connected to the output end of the first motor 2. A second gear 4 meshes with the outer side of the first gear 3. A winding roller 5 is fixedly connected to the outer side of the second gear 4. A support block 301 is rotatably connected to the outer side of the first gear 3. A plug rod 302 is slidably connected to the outer side of the support block 301. A slot 303 is formed on the surface of the first gear 3. The slot 303 and the plug rod 302 cooperate. A clamping screw 6 is rotatably connected to the inner side of the support block 301. A clamping plate 7 is threadedly connected to the outer side of the clamping screw 6. The clamping plate 7 and the support block 301 are slidably connected. A fixing block 8 is fixedly connected to the outer side of the base 1. A second motor 9 is fixedly connected to the outer side of the fixing block 8. A third gear 10 is fixedly connected to the output end of the second motor 9. A lifting screw 11 is rotatably connected to the outer side of the fixing block 8. A lifting plate 12 is threadedly connected to the outer side of the lifting screw 11. Semicircular plates 1 are rotatably connected to the inner sides of both the lifting plate 12 and the fixing block 8. 3. A fixing strip 14 is fixedly connected to the inner side of the semicircular plate 13 on one side, and a semi-gear ring 15 is fixedly connected to the outer side of the semicircular plate 13. The semi-gear ring 15 and the third gear 10 are used in conjunction. In this step, by setting the first gear 3, the winding roller 5, the semicircular plate 13 and the semi-gear ring 15, the copper wire is first tightly wound around the outer side of the winding roller 5, then one end is pulled out and wound around the outer side of the fixing strip 14, then the lifting plate 12 is lowered, and one side of the coil is placed between the clamping plate 7 and the support block 301, and the other side is placed between the semicircular plates 13, and then the semi-gear ring 10 is lowered. The circular plate 13 returns to its original position, and the second motor 9 drives the semi-gear ring 15 to rotate, causing the semi-circular plate 13 to rotate one end of the copper wire around the coil. At the same time, the first motor 2 drives the coil and the take-up roller 5 to rotate in opposite directions, so that the take-up roller 5 can stably tighten the copper wire. Thus, when the copper wire moves, a uniform tension force is applied to it, and through the rotation of the coil, the copper wire can be evenly wound around the outside of the coil. This achieves uniform tightening and winding of the copper wire during winding, making the production of the coil more stable and improving the stability of the device.

[0024] Furthermore, such as Figure 1 and Figure 4 As shown, a spring 16 is fixedly connected to the outside of the fixing block 8, and a push plate 17 is fixedly connected to one end of the spring 16. The push plate 17 and the fixing block 8 are slidably connected. By setting the spring 16 and the push plate 17, when the copper wire is wound, the spring 16 pushes the push plate 17 to stick to the coil, thereby limiting and blocking the copper wire wound by the device, making it less likely to be excessively dispersed during winding, and improving the stability of the device.

[0025] Furthermore, such as Figure 4As shown, a fixing plate 18 is slidably connected to the inner side of the fixing block 8, and the fixing plate 18 and the push plate 17 are used together. By setting the fixing plate 18, when the push plate 17 is not needed, the fixing plate 18 can be pulled out from the inner side of the fixing block 8 to block the lower side of the push plate 17, making it difficult for the push plate 17 to move down, thus improving the stability of the device.

[0026] Furthermore, such as Figure 2 As shown, a guide plate 19 is fixedly connected to the outer side of the base 1, and an elastic pad 20 is fixedly connected to the outer side of the guide plate 19. By setting the guide plate 19, when the winding roller 5 releases the copper wire, the guide plate 19 blocks it, making it less likely to come into contact with the coil during unwinding and cause wear, thus further improving the stability of the device.

[0027] Furthermore, such as Figure 2 As shown, a limiting plate 21 is threadedly connected to the outer side of the take-up roller 5. The limiting plate 21 and the semi-circular plate 13 are used in conjunction. This step, by setting the limiting plate 21 and screwing the limiting plate 21 to the outer side of the take-up roller 5, further restricts the position of the copper wire when the take-up roller 5 is unwinding the copper wire, thereby improving the stability of the device operation.

[0028] Furthermore, such as Figure 1 As shown, a friction pad 22 is fixedly connected to the outer side of the base 1, and a suction cup 23 is fixedly connected to the outer side of the base 1. This step, by setting the friction pad 22 and the suction cup 23, makes it easy for the device to be adsorbed onto the installation location by the suction cup 23, and the friction pad 22 is used to press against the device to increase the friction coefficient between the device and the installation location, thereby facilitating the placement and installation of the device and improving the convenience of using the device.

[0029] The working principle is as follows: First, the copper wire is tightly wound around the outside of the take-up roller 5. Then, one end is pulled out and wound around the outside of the fixing strip 14. Next, the lifting screw 11 is rotated, which drives the lifting plate 12 to move down, causing the two semi-gear rings 15 to separate. One side of the coil is placed between the clamping plate 7 and the support block 301, and the other side is placed between the semi-circular plates 13. Then, the semi-circular plates 13 are returned to their original positions. The second motor 9 drives the semi-gear rings 15 to rotate, so that the semi-circular plates 13 drive one end of the copper wire to start rotating around the coil. At the same time, the first motor 2 drives the coil and the take-up roller 5 to rotate in opposite directions, so that the take-up roller 5 can stably tighten the copper wire, and then move the copper wire. When in motion, apply a uniform tension force and allow the copper wire to be evenly wound around the outside of the coil through the rotation of the coil. When the copper wire is about to be wound around the coil that is blocked by the clamping plate 7, the user first holds the coil, then rotates the clamping screw 6 to separate the clamping plate 7 from the coil. Then, pull the insertion rod 302 out of the slot 303, and then rotate the support block 301 to drive the insertion rod 302 to rotate to the slot 303 on the other side, thereby adjusting its clamping position to the position of the coil with the copper wire already wound. Then, move the clamping plate 7 again to cooperate with the support block 301 to fix the coil, and continue to wind the coil. Finally, cut off the excess copper wire and take out the coil.
