Description

Technical Field

[0001] This utility model relates to the field of coil technology, and more specifically, to a hollow coil tangent device. Background Technology

[0002] A hollow coil consists of two parts: the hollow core and the coil itself. As the name suggests, the hollow core has no center. The coil is made of individual wires wound around each other, insulated from one another. When current flows through the wires, a magnetic field is generated around the coil. The strength of this magnetic field is directly proportional to the strength of the current flowing through the coil and the number of turns. Similarly, within a given magnetic field, the coil cuts through magnetic lines of force, converting the magnetic field into electrical energy. This magnetoelectric conversion principle can be used to create relays, motors, electric motors, wireless devices, speakers, and other devices. The wires can be made of metals such as copper, iron, aluminum, or gold. A metallic magnetic device can be inserted into the center of the coil to enhance the magnetic field generated when current flows through it. When the coil has only a plastic frame or no frame at all, it forms a hollow coil. Hollow coils have a wide range of applications, and to meet various needs, they are designed in circular, square, oval, and various irregular shapes.

[0003] Chinese Patent Publication No. CN221281912U discloses a winding machine, including a base. The upper surface of the base is fitted with a spool groove, a spool installer, a spring, a baffle, fixing bolts, a sliding plate, a transverse base, a drive motor, a threaded post, and a wire seat. The technical effects and advantages of this invention are: The invention has a reasonable structure. A plastic spool is pushed down by a slider and a top plate, and a copper wire spool is inserted into a support frame. A storage drawer stores the wound plastic spool. Multiple plastic spools are placed in the spool groove. The spool installer is slid by the palm to align the plastic spool with the rotating shaft. The baffle blocks the outlet of the spool groove, and the spring resets the baffle, causing the plastic spool to fall onto the sliding plate and then into the storage drawer. The rotating motor rotates the rotating shaft to wind the copper wire onto the plastic spool. The drive motor rotates the threaded post to move the wire seat at a uniform speed. Through the rotating shaft, plastic spool, and baffle, the machine is small in size, easy to move, and facilitates product processing, reducing manufacturing difficulty.

[0004] However, the existing technical solutions mentioned above have the following drawbacks: when using a winding machine, workers need to manually cut the copper wire body to complete the winding of the hollow coil, which is cumbersome, poses a threat to the safety of workers, and reduces the production efficiency of the winding machine.

[0005] Therefore, it is necessary to provide a hollow coil tangent device to solve the above problems. Utility Model Content

The upper surface of the base is fitted with a spool groove, a spool installer, a spring, a baffle, fixing bolts, a sliding plate, a transverse base, a drive motor, a threaded post, and a wire seat. The technical effects and advantages of this invention are: The invention has a reasonable structure. A plastic spool is pushed down by a slider and a top plate, and a copper wire spool is inserted into a support frame. A storage drawer stores the wound plastic spool. Multiple plastic spools are placed in the spool groove. The spool installer is slid by the palm to align the plastic spool with the rotating shaft.

Through the rotating shaft, plastic spool, and baffle, the machine is small in size, easy to move, and facilitates product processing, reducing manufacturing difficulty.

[0025] However, the existing technical solutions mentioned above have the following drawbacks: when using a winding machine, workers need to manually cut the copper wire body to complete the winding of the hollow coil, which is cumbersome, poses a threat to the safety of workers, and reduces the production efficiency of the winding machine.

[0026] Therefore, it is necessary to provide a hollow coil tangent device to solve the above problems.

[0027] Therefore, in order to improve the problem of requiring workers to manually cut the main body of the copper wire in the relevant technology.

[0028] Please see Figure 1 and Figure 3 A hollow coil cutting device includes a workbench 1, a cutting assembly 2, a wire assembly 3, a winding mechanism 4, and a wire exit assembly 5. The wire assembly 3, the winding mechanism 4, and the wire exit assembly 5 are all mounted on the workbench 1. The wire assembly 3 is used to guide the copper wire, the winding mechanism 4 is used to wind the copper wire, and the wire exit assembly 5 is used to exit the copper wire.

[0029] Please see Figure 1 The lead-out assembly 5 includes a support frame 51 and a second rotating shaft 52. The support frame 51 is provided on the upper surface of the workbench 1. The second rotating shaft 52 is fixedly connected to one side of the support frame 51. A lead-out roller 6 is sleeved on the outer surface of the second rotating shaft 52. The lead wire assembly 3 includes a lead wire base 31 and a lead wire seat 32. The lead wire base 31 is fixedly connected to the workbench 1. The lead wire seat 32 is provided on the lead wire base 31. A through hole 8 is provided on the lead wire seat 32.

[0030] With this setup, when the operator needs to use the hollow coil cutting device, the required lead roller 6 is first fitted onto the second rotating shaft 52. Then, one end of the copper wire is pulled out from the lead roller 6, and the lead roller 6 rotates on the second rotating shaft 52 to guide the copper wire towards the conductor seat 32. The copper wire passes through the through hole 8 on the conductor seat 32 and is then guided onto the winding assembly for winding. The through hole 8 prevents the copper wire from swinging during winding, thus improving the stability of the copper wire during winding.

[0031] Optionally, in some embodiments, please refer to Figure 2 and Figure 3The winding mechanism 4 includes a first drive motor 41, a first mounting plate 42, a first rotating shaft 43, a winding roller 44, a fixing component 45, and a sliding component 46. The first mounting plate 42 is mounted on the sliding component 46, and the first drive motor 41 is mounted on the first mounting plate 42. The first rotating shaft 43 is fixedly connected to the output shaft of the first drive motor 41, and the winding roller 44 is sleeved on the outer surface of the first rotating shaft 43. The fixing component 45 includes a fixing plate 451 and limiting posts 452. The fixing plate 451 is provided on the end of the first rotating shaft 43 away from the first drive motor 41. Two limiting holes 9 are provided on the side of the winding roller 44 away from the first drive motor 41. Two limiting posts 452 are fixedly connected to the side of the fixing plate 451 away from the first drive motor 41. Furthermore, each of the limiting posts 452... The sliding assembly 46, which is inserted into the corresponding limiting hole 9, includes a second drive motor 461, a second mounting plate 462, a guide rod 463, a lead screw 464, and a slider 465. The second mounting plate 462 is fixedly connected to the worktable 1, the second drive motor 461 is mounted on the second mounting plate 462, the guide rod 463 is fixedly connected to the second mounting plate 462, the lead screw 464 is rotatably connected to the second mounting plate 462, and one end of the lead screw 464 is connected to the output shaft of the second drive motor 461. The slider 465 is sleeved on the guide rod 463 and the lead screw 464, and the first mounting plate 42 is mounted on the slider 465. A nut 10 is provided on the end of the first rotating shaft 43 away from the first drive motor 41, and the nut 10 is threadedly connected to the first rotating shaft 43.

[0032] With this setup, when the operator needs to use the hollow coil cutting device, the operator guides the copper wire to the winding roller 44, winds it once, and then passes the copper wire through the limiting hole 9 on the winding roller 44. One end of the copper wire is then wound around the limiting post 452 on the fixed plate 451, which secures one end of the copper wire and prevents it from becoming loose on the winding roller 44, thus preventing problems with subsequent winding operations. Then, the operator starts the first drive motor 41, causing the first rotating shaft 43 to rotate. The winding roller 44 on the first rotating shaft 43 also rotates accordingly, winding the wire... The copper wire on the winding roller 44 will be wound around the winding roller 44 as the winding roller 44 rotates. At this time, the second drive motor 461 starts, and the lead screw 464 connected to the output shaft of the second drive motor 461 rotates. The slider 465 sleeved on the lead screw 464 will slide back and forth on the lead screw 464 and the guide rod 463 as the lead screw 464 rotates. This allows the copper wire wound on the winding roller 44 to be evenly wound around the winding roller 44 and wound into the desired coil. After the winding is completed, the first drive motor 41 and the second drive motor 461 are stopped.

[0033] Optionally, in some embodiments, please refer to Figure 1 The tangent assembly 2 includes a fixed frame 21, a first cutting blade 22, a second cutting blade 23, and an electric push rod 24. The fixed frame 21 is mounted on the workbench 1 and has a sliding groove 7. The first cutting blade 22 is fixedly connected to the fixed frame 21. An electric push rod 24 is mounted on the top of the fixed frame 21. The second cutting blade 23 is fixedly connected to the output shaft of the electric push rod 24 and slides on the sliding groove 7.

[0034] With this setup, when the operator needs to use the hollow coil cutting device, after the copper wire is wound on the winding roller 44, the operator starts the electric push rod 24. The first cutting blade 22 on the output shaft of the electric push rod 24 moves towards the second cutting blade 23. The lower cutting edge of the first cutting blade 22 is tangent to the upper cutting edge of the second cutting blade 23. The copper wire located between the first cutting blade 22 and the second cutting blade 23 will be cut off, completing the cutting of the copper wire body. This achieves automatic separation of the hollow coil from the copper wire body, improving the efficiency of coil production, reducing operator operations, and increasing portability.
