Abstract
Description
Technical Field
[0001] The utility model relates to the field of coil winding, in particular to a material feeding mechanism for winding a magnetic core coil. Background Art
[0002] A magnetic core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability, high magnetic flux density, and low loss. Nickel-zinc ferrite has extremely high impedance and low magnetic permeability of less than a few hundred. Ferrite magnetic cores are used in coils and transformers of various electronic devices.
[0003] However, when winding a magnetic core coil, due to the relatively fast winding speed, directly feeding the wire through a wire roller easily leads to uneven winding. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a material feeding mechanism for winding a magnetic core coil, which solves the problems mentioned in the above background.
[0005] The utility model provides the following technical solutions: A material feeding mechanism for winding a magnetic core coil includes a winding frame. A winding roller is arranged inside the winding frame. A wire feeding frame is arranged on one side of the winding roller. A reciprocating lead screw is installed inside the wire feeding frame. A material feeding mechanism is arranged on the outer side of the reciprocating lead screw. The material feeding mechanism includes: a material feeding frame, a swing arm frame, and a pressure swing arm. A material feeding pulley is installed inside the upper end of the material feeding frame. An embedded groove is opened at the lower end of the pressure swing arm. A limiting guide plate is installed on the side surface of the winding frame below the material feeding mechanism. A wire pulling mechanism is arranged below the limiting guide plate. The wire pulling mechanism includes: a first sliding guide block, a second sliding guide block, and a wire pulling ring. A sliding rail is arranged between the first sliding guide block and the second sliding guide block and the limiting guide plate.
[0006] As a further scheme of the utility model: A limiting groove is opened on the lower surface of the material feeding mechanism. A threaded hole is opened inside the material feeding frame on the outer side of the reciprocating lead screw. A wire roller is arranged inside the winding frame.
[0007] As a further scheme of the utility model: A second driven runner is installed on the outer side of the winding frame at the end of the winding roller. A first driven runner is installed at the end of the reciprocating lead screw. A driving runner is arranged between the first driven runner and the second driven runner.
[0008] As a further scheme of the utility model: A rotating shaft is installed between the pressure swing arm and the swing arm frame.
[0009] As a further solution of the present utility model: both the first sliding guide block and the second sliding guide block are slidably connected to the sliding rail.
[0010] As a further solution of the present utility model: the threaded hole is in meshing rotational connection with the reciprocating lead screw.
[0011] As a further solution of the present utility model: the feeding pulley is rotatably connected to the feeding rack.
[0012] As a further solution of the present utility model: a transmission belt is connected between the driving runner, the first driven runner and the second driven runner.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] After the wire is aligned with the inner embedded groove at the lower end of the pressure material swing arm and then wound around the outside of the winding roller, when feeding the wire, the feeding pulley and the inner embedded groove at the end of the material swing arm can ensure the positioning and guiding transmission of the wire, avoiding unevenness during winding.
[0015] Control the second sliding guide block and the first sliding guide block as a whole to move towards the end of the winding frame on the outside of the sliding rail respectively. The wire pulling ring will pull the wire wound on the wire roller outwards. The alternating movement of the first sliding guide block and the second sliding guide block can ensure that there is a slack wire supply when the feeding mechanism as a whole feeds the wire, reducing the resistance during winding.

Detailed implementation mode
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] As Figures 1-5 shown, this embodiment provides a feeding mechanism for winding a magnetic core coil, including a winding frame 1. A winding roller 2 is arranged inside the winding frame 1. A wire pay-off frame 3 is arranged on one side of the winding roller 2. A reciprocating lead screw 4 is installed inside the wire pay-off frame 3. A feeding mechanism 5 is arranged on the outer side of the reciprocating lead screw 4. The feeding mechanism 5 includes: a feeding rack 501, a swing arm frame 505, and a pressing arm 506. A rotating shaft is installed between the pressing arm 506 and the swing arm frame 505. A feeding pulley 504 is installed inside the upper end of the feeding rack 501. The feeding pulley 504 is rotatably connected to the feeding rack 501. An embedded groove 507 is opened at the lower end of the pressing arm 506. A limiting guide plate 6 is installed on the side surface of the winding frame 1 below the feeding mechanism 5. A wire pulling mechanism is arranged below the limiting guide plate 6. The wire pulling mechanism includes: a first sliding guide block 601, a second sliding guide block 602, and a wire pulling loop 605. A sliding rail 604 is arranged between the first sliding guide block 601 and the second sliding guide block 602 and the limiting guide plate 6. The first sliding guide block 601 and the second sliding guide block 602 are both slidably connected to the sliding rail 604.
[0024] As Figures 2-3 shown, in this embodiment, a limiting groove 502 is opened on the lower surface of the feeding mechanism 5. A threaded hole 503 is opened inside the feeding rack 501 on the outer side of the reciprocating lead screw 4. The threaded hole 503 is meshed and rotatably connected to the reciprocating lead screw 4. A wire roller 603 is arranged inside the winding frame 1. A second driven runner 8 is installed on the outer side of the winding frame 1 at the end of the winding roller 2. A first driven runner 7 is installed at the end of the reciprocating lead screw 4. A driving runner 9 is arranged between the first driven runner 7 and the second driven runner 8. A transmission belt is connected between the driving runner 9 and the first driven runner 7 and the second driven runner 8.
[0025] The working principle of the present utility model is as follows: during use, after the thread end part outside the thread roller 603 is integrally drawn out and respectively inserted into the sliding rails 604 at the ends of the first sliding guide block 601 and the second sliding guide block 602, the thread end is then passed through the inside of the unwinding rack 501 and wound around the outside of the unwinding pulley 504. Then, the thread is aligned with the inner embedding groove 507 at the lower end of the pressing arm 506 and then wound around the outside of the winding roller 2. By driving the driving active runner 9 to drive the first driven runner 7 and the second driven runner 8 to rotate simultaneously, the reciprocating lead screw 4 and the winding roller 2 are respectively driven to rotate integrally. The rotating winding roller 2 winds the thread. At the same time, the rotation of the reciprocating lead screw 4 drives the threaded hole 503 inside the unwinding rack 501 to slide reciprocally, controlling the movement of the entire unwinding mechanism 5 following the movement of the thread wound around the outside of the winding roller 2. Before the unwinding mechanism 5 needs to move to the left, first control the second sliding guide block 602 to move towards the end of the winding rack 1 on the outside of the sliding rail 604. The wire pulling ring 605 will pull the thread wound on the thread roller 603 outwards. When the entire unwinding mechanism 5 moves, at this time, the second sliding guide block 602 moves back to the central position of the winding rack 1, and at the same time, the first sliding guide block 601 pulls towards the end of the winding rack 1. Thus, the alternating movement of the first sliding guide block 601 and the second sliding guide block 602 can ensure that there is a slack thread supply during the entire wire release of the unwinding mechanism 5, reducing the resistance during winding.
