Description

Technical Field

[0001] This utility model relates to the field of electromagnetic coil winding technology, specifically to a hook coil. Background Technology

[0002] In the manufacturing of inductor coils, winding copper wire onto a magnetic ring is a crucial step. The traditional winding method relies entirely on a hook to pull the unwound wire from top to bottom of the magnetic ring. This method has the following drawbacks:

[0003] 1. Because the crochet hook rubs against the unwound yarn along its entire length with each turn, the yarn wears out very quickly.

[0004] 2. After the unwound wire is pulled down by the hook, the end of the wire hangs freely without any other constraints. The copper wire is prone to deformation and bending, and its position is out of control. Therefore, the longer the wire, the more difficult it is to control the position of its end. In addition, the end of the wire is prone to getting caught in other structural components of the winding equipment, causing problems such as wire breakage and damage to the insulation layer of the wire.

[0005] Therefore, how to collect long, unwound copper wires during inductor winding, control the position of the wire tail, and reduce wear on the wire tail during the winding process have become urgent technical problems to be solved. Utility Model Content

[0006] This utility model addresses the existing technical problems by providing a hook reel.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hook reel includes a rotary drive mechanism and a support ring. The output end of the rotary drive mechanism is connected to the support ring and is used to drive the support ring to rotate. A hook is provided on the outer side of the support ring.

[0008] The beneficial effects of this utility model are as follows: During use, the hook on the outside of the support ring moves in a circular motion as the support ring rotates. As the rotation drive mechanism drives the support ring to continue rotating, since the end of the copper wire (i.e. the wire tail) is in a free state, the copper wire tail is continuously wound onto the support ring under the pull of the hook until all the remaining copper wire is wound onto the support ring. Therefore, there will be no situation where it gets wound into other equipment, ensuring the safety of the winding process. The controllable position of the wire tail allows this solution to meet the winding requirements of longer copper wires.

[0009] Based on the above technical solution, the present invention can be further improved as follows:

[0010] Preferably, the outer side of the support ring is covered with an outer baffle, and a wire-receiving space is provided between the outer baffle and the support ring. The outer baffle is provided with a wire hook. The wire hook catches the copper wire located at the wire hook, and the copper wire to be wound enters the receiving space through the wire hook, thus storing the copper wire and preventing the end of the copper wire from entering other equipment, further improving the storage effect of the copper wire and improving the safety of use.

[0011] Preferably, the hook has a groove opening.

[0012] Preferably, the groove opening is U-shaped or V-shaped. The inner surface of the V-shaped opening is a smooth arc surface, and the hook is made of Teflon or polyoxymethylene (POM), which has a low coefficient of friction, reducing the friction on the copper wire. In particular, the bending radius of the smooth arc surface of the inner surface of the V-shaped opening is much larger than the bending radius of the hook hook position. When the copper wire is pulled by the V-shaped opening, the bending angle of the copper wire is not too large, avoiding damage to the copper wire and the insulation layer.

[0013] Preferably, a roller is installed at the opening of the groove to further convert the dynamic friction with the copper wire into static friction, thereby further reducing wear on the copper wire.

[0014] Preferably, an upper support plate is installed at the upper end of the support ring, and a lower support plate is installed at the lower end of the support ring.

[0015] Preferably, the outer edge of the upper support plate is provided with an upper retaining ring, the outer edge of the lower support plate is provided with a lower retaining ring, and the hook is located between the upper retaining ring and the lower retaining ring.

[0016] Preferably, the rotary drive mechanism includes a motor and a reducer, the output end of the motor is connected to the reducer, and the output end of the reducer is connected to the lower support plate and the upper support plate.

[0017] Preferably, the rotary drive mechanism is a stepper motor or a servo motor. Attached Figure Description

[0027] Example 1

[0028] Reference Figures 1 to 5 As shown, this utility model discloses a wire hook reel, including a rotary drive mechanism and a support ring 5. The support ring 5 is circular or cylindrical, which reduces bending of the copper wire, reduces damage to the copper wire, and ensures the service life of the copper wire. The output end of the rotary drive mechanism is connected to the support ring 5, driving the support ring 5 to rotate to realize the copper wire collection action, and can stop at any position according to the winding situation. A wire hook 6 is provided on the outside of the support ring 5, which is used to hook the copper wire.

[0029] The hook 6 has a groove opening; in this embodiment, the hook 6 has a V-shaped opening, and a roller 8 is installed at the V-shaped opening. In this example, the hook reel is horizontally positioned, and the V-shaped opening is horizontally oriented. When the hook 6 rotates with the support ring 5, it hooks the copper wire. As the support ring 5 further rotates, the copper wire is pulled forward by the groove opening, causing it to wrap around the support ring 5. The roller 8 has a radius of curvature much larger than that of the hook, significantly reducing the bending angle of the copper wire. It also converts dynamic friction into static friction, further reducing wear on the copper wire from the hook 6, minimizing damage, and ensuring smooth movement of the copper wire along the hook 6. Because the wire maintains a certain tension throughout the process, the hook reel is not limited to a horizontal setting; it can also be vertical or inclined.

[0030] In an optional embodiment, the groove opening is U-shaped, which can also achieve the function of hooking copper wire. Furthermore, a roller 8 is installed at the U-shaped opening to further reduce wear on the copper wire.

[0031] In this embodiment, specifically, the support ring 5 is a circular ring. An upper support plate 7 is installed at the upper end of the support ring 5, and a lower support plate 4 is installed at the lower end of the support ring 5. The rotation drive mechanism includes a motor 1 and a reducer 2. The output end of the motor 1 is connected to the reducer 2, and the output end of the reducer 2 is connected to the lower support plate 4 and the upper support plate 7. Alternatively, the upper support plate 7 is connected to the lower support plate 4, and the lower support plate 4 is connected to the output end of the reducer 2. The motor 1 and the reducer 2 drive the support ring 5 to rotate or stop. By setting the support ring 5 to a circular shape, the weight of the support ring 5 can be reduced, the output power of the motor 1 can be reduced, the inertia can be reduced, and the sensitivity of the action can be improved. By setting the upper support plate 7 and the lower support plate 4, the structural strength of the support ring 5 can be increased, and its deformation can be reduced.

[0032] Furthermore, the upper support plate 7 has an upper retaining ring on its outer edge, and the lower support plate 4 has a lower retaining ring on its outer edge. The wire hook 6 is located between the upper and lower retaining rings. The upper and lower retaining rings limit the movement of the copper wire. Together with the support ring 5 and the outer baffle 3, they form a wire-holding space, preventing the copper wire from coming out of the wire-holding space and preventing the copper wire from winding into other equipment, thus ensuring safety during winding.

[0033] In an optional embodiment, the rotary drive mechanism is a stepper motor or a servo motor, which can also drive the support ring 5 to rotate.

[0034] The usage process of this utility model is as follows:

[0035] See Figures 3 to 5As shown, the wire feeding mechanism 9 feeds copper wire to the wire clamping mechanism 10. The wire clamping mechanism 10 clamps the end of the copper wire. After the wire clamping mechanism 10 clamps the end, the wire feeding mechanism 9 releases and retracts. At this time, the copper wire is above the magnetic ring 11. The hook 12 passes upward through the inner hole of the magnetic ring 11. After the height of the hook 12 exceeds the copper wire, the hook 12 rotates at a certain angle to hook the copper wire, and then moves downward, using the hook on the hook 12 to hook the copper wire down. See [reference needed]. Figure 3 As shown; after the copper wire is pulled below the magnetic ring 11, the hook 12 rotates 90 degrees, changing the arrangement of the two segments of the copper wire at the V-shaped angle from left-right to front-back in the view plane. At this time, one strand of copper wire will enter the hook range of the hook 6 on the surface of the support ring 5. Then the support ring 5 rotates, and the copper wire gets into the hook 6 of the support ring 5. Under the continued rotation of the support ring 5, the hook 6 pulls the copper wire to move, as... Figure 4 As shown, during this process, the clamping mechanism 10 maintains a firm grip on the copper wire, while the feeding mechanism 9 continuously feeds the wire while maintaining a certain tension, until the required length of copper wire is wound onto the support ring 5. The feeding mechanism 9 then presses the copper wire tightly, the clamping mechanism 10 releases the wire end, and the support ring 5 continues to rotate, pulling down the wire end and winding the copper wire around the outer circumference of the support ring 5, thus achieving the storage of the copper wire. Figure 5 As shown.

[0036] This device can reduce the bending deformation of copper wires and prevent them from getting tangled in other equipment. At the same time, the angle of rotation of the support ring 5 determines the length of the stored wire. This angle can be changed according to the actual wire length required by the product. The circumference of the support ring 5 is 3.14 times its diameter, which can significantly reduce the size of the wire storage mechanism and reduce the space occupied.

[0037] Example 2

[0038] Reference Figure 6 As shown, an outer baffle 3 is provided on the outer side of the support ring 5. The outer baffle 3 is arc-shaped and is mounted on the support frame (not shown in the figure). A wire-accommodating space is provided between the outer baffle 3 and the support ring 5. The outer baffle 3 has a hook opening, which facilitates the hook 6 to hook the copper wire at the hook opening. Furthermore, the hook opening extends through the outer baffle 3 in the height direction, facilitating the smooth entry of the copper wire into the hook range of the hook 6. In use, the vertical copper wire located at the hook opening of the outer baffle 3 is inserted into the hook 6. As the support ring 5 rotates, the copper wire is wound around the support ring 5. By setting the outer baffle 3 on the outside of the support ring 5, the copper wire storage effect is further improved, solving the problem of the copper wire winding into other equipment, ensuring the safety of the winding process, and the more controllable position of the wire end allows this solution to meet the winding needs of longer copper wires.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
