[0001] The invention relates to the field of winding machines, and in particular to a magnetic bar winding machine, a magnetic bar and skeleton winding system and a winding method thereof. Background Art

[0002] In the electronics and electrical industry, the winding of magnetic rods and bobbins is an important manufacturing process, which is widely used in the production process of electronic components such as transformers and inductors. Traditional methods of winding magnetic rods and bobbins mostly rely on manual operation, which is not only inefficient, but also difficult to ensure the accuracy and consistency of winding. With the development of automation technology, some automated winding equipment has gradually appeared on the market, but these equipment often have limitations in structure and function, and cannot meet the needs of efficient and accurate winding of magnetic rods and bobbins at the same time.

[0003] Specifically, traditional winding equipment can usually only wind the magnetic rod or the skeleton separately, but lacks the function of effectively connecting the two and winding them at the same time. This requires additional steps and equipment to complete the connection between the magnetic rod and the skeleton during the manufacturing process, increasing production costs and complexity. In addition, traditional winding equipment often has difficulty in ensuring the uniform distribution and tight fit of the copper wire during the winding process, affecting the electrical performance and reliability of the final product. Summary of the invention

[0009] The wire located between the first wire nozzle outlet end and the second wire nozzle inlet end is set as a winding segment, and the first winding arm and the second winding arm are respectively driven by the moving module to move horizontally and vertically and rotate around the horizontal axis, so that the winding segment has a corresponding spatial position and posture.

[0010] Preferably, the outlet end of the first wire nozzle has a winding station which is located on the opposite side of the horizontal plane and the vertical plane where the carrying part is located relative to the inlet end of the second wire nozzle under the drive of the moving module.

[0011] Preferably, the carrying parts are arranged in plurality on the base along the length direction of the first winding arm or the second winding arm, and the first wire nozzle and the second wire nozzle are arranged in plurality and are arranged corresponding to the plurality of carrying parts.

[0012] A magnetic bar and skeleton winding system, wherein the skeleton is pre-installed outside a first wire nozzle, and a pin fixer is fixed to the first winding arm adjacent to the first wire nozzle, and the pin fixer abuts against the pin of the skeleton to limit the direction of the pin of the skeleton.

[0013] Preferably, a skeleton carrier is provided on the base, and the skeleton carrier has a loading groove for accommodating the skeleton, and a retaining wall is provided on the side of the loading groove away from the base; the skeleton carrier is connected to an assembly driver, and the assembly driver can drive the skeleton carrier to move toward the base, so that the retaining wall abuts against the skeleton, thereby pushing the skeleton to move.

[0014] Preferably, the skeleton carrier is connected to the base via a lifting mechanism, and the lifting mechanism drives the skeleton carrier to perform a lifting action.

[0015] A winding method comprises the following steps:

[0016] S1, the moving module drives the first winding arm and the second winding arm to move, so that the first wire nozzle is located at one end of the second wire nozzle close to the wire feeding device and is coaxially arranged with the second wire nozzle;

[0017] S1.1, the first winding arm and the second winding arm move toward the carrying portion at different distances, so that the distance between the first wire nozzle and the second wire nozzle increases, forming a winding segment of the copper wire;

[0019] S2, the moving module drives the first nozzle to move to an assembly station close to the magnetic bar and coaxial with the magnetic bar;

[0020] S2.1. The skeleton carrier can enter the assembly station through the lifting mechanism, and under the drive of the assembly driver, it abuts against the skeleton through the retaining wall to push the skeleton onto the outer wall of the magnetic rod;

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with specific embodiments:

[0037] A magnetic bar winding machine, using copper wire to Figure 1 The magnetic bar 100 is shown wound.

[0038] like Figure 2 As shown, it comprises a base 1, a wire supply device 2 is installed on the top of the base 1, a carrying portion 3 is provided in the middle and a winding device is movably installed.

[0039] In the present application, the carrying part 3 is constructed as a pair of clamps, and the magnetic bar 100 is clamped in the carrying part 3 in the horizontal direction. The wire supply device 2 is used to provide the copper wire required for winding, and the copper wire output by the wire supply device 2 will enter the winding device. The winding device includes a first winding arm 4 and a second winding arm 5, as shown in FIG. Figure 3 and Figure 4 As shown, the first winding arm 4 and the second winding arm 5 are respectively provided with a first wire nozzle 41 and a second wire nozzle 51 for the copper wire to pass through, and the second winding arm 5 is provided with a locking device corresponding to the second wire nozzle 51, which can fix the copper wire passing through the second wire nozzle 51, so that the winding device can pull the copper wire.

[0040] The portion of the copper wire between the outlet end of the first wire nozzle 41 and the inlet end of the second wire nozzle 51 is used as a winding segment, and the copper wire of the winding segment is used for winding the magnetic bar 100 and the skeleton 200 .

[0041] like Figure 2 As shown, the first winding arm 4 and the second winding arm 5 are respectively connected to a moving module 6, and under the control of the moving module 6, they move in the horizontal and vertical directions and rotate around the horizontal axis, thereby changing the spatial position of the outlet end of the first wire nozzle 41 and the inlet end of the second wire nozzle 51, and then controlling the position and posture of the copper wire winding segment, so that the winding segment corresponds to the magnetic bar 100 or the skeleton 200 that needs to be wound. In addition, the moving module 6 is also responsible for driving the corresponding first winding arm 4 or second winding arm 5 to rotate around the wound magnetic bar 100 or the skeleton 200 to wind the copper wire.

[0042] When winding, the magnetic bar 100 is first wound, and the specific steps are as follows:

[0043] like Figure 5 As shown, the moving module 6 drives the first winding arm 4 and the second winding arm 5 to move, so that the first wire nozzle 41 is located above the second wire nozzle 51 and is coaxially arranged.

[0044] The copper wire is passed through the first wire nozzle 41 and the second wire nozzle 51 , and the copper wire in the second wire nozzle 51 is fixed by a locking device.

[0045] The first winding arm 4 and the second winding arm 5 are lowered by different distances, so that when the winding device moves toward the carrying portion 3, the distance between the first wire nozzle 41 and the second wire nozzle 51 increases, forming a winding segment of the copper wire.

[0046] At this time, the second wire mouth 51 fixed to the copper wire is located below the first wire mouth 41. If the second wire mouth 51 is used to run around the magnetic bar 100 for winding, during the winding process, the traction end connected to the copper wire and the winding device and the wire feeding device 2 are separated by the copper wire already attached to the magnetic bar 100. As a result, the second winding arm 5 needs to overcome the friction between the copper wire already attached to the magnetic bar 100 and the magnetic bar 100 in order to wind the newly output copper wire from the wire feeding device 2 around the magnetic bar 100, thereby causing difficulty in operating the system.

[0047] Therefore, before the copper wire is wound on the magnetic bar 100, the present application Figure 6 As shown, the movable module 6 drives the first winding arm 4 located above to flip outward, and at the same time, the second winding arm 5 located below flips inward, so that the outlet end of the flipped first wire nozzle 41 is located below the inlet end of the flipped second wire nozzle 51, and the winding segment is inclined.

[0048] Then, combined Figure 7 As shown, the winding device descends so that the winding segments are staggered and abut against the magnetic bar 100. At this time, the first wire nozzle 41 is located at the winding station, that is, the first winding arm 4 is located on the side of the carrying part 3 away from the base 1, so that the first winding arm 4, which is slidably connected to the copper wire, has space to move around the magnetic bar 100. When the first winding arm 4 is winding around the magnetic bar 100, the new copper wire output by the wire supply device 2 can be directly attached to the magnetic bar 100.

[0049] The present application also provides a magnetic bar and skeleton winding system, which is used to put the skeleton 200 on the magnetic bar 100 after completing the winding work on the magnetic bar 100, and continue to wind the copper wire connecting the magnetic bar 100 on the pin 300 of the skeleton 200, so that the magnetic bar 100 is connected to the skeleton 200.

[0050] In this application, if Figure 3 As shown, the frame 200 is pre-mounted on the outer edge of the first wire nozzle 41, and the first winding arm 4 is provided with a pin holder 42 adjacent to the first wire nozzle 41 to abut against the pin 300 on the frame 200. Before assembling the frame 200 on the magnetic bar 100, the moving module 6 drives the first wire nozzle 41 to move to an assembly station close to the magnetic bar 100 and coaxial with the magnetic bar 100. Figure 8 As shown, a skeleton carrier 7 is disposed at the bottom end of the base 1 . When the skeleton 200 needs to be assembled, the skeleton carrier 7 can enter the assembly station through a lifting mechanism 73 .

[0051] like Fig. 9 As shown, the skeleton carrier 7 has a loading slot 71 for accommodating the skeleton 200, and a retaining wall 72 is provided at one end of the loading slot 71 away from the base 1. The retaining wall 72 abuts against the end of the skeleton 200 when in the assembly station, so that when the skeleton carrier 7 moves toward the base 1 under the drive of the assembly driver 74, the skeleton 200 can be pushed onto the magnetic rod 100. At this time, the two groups of pins 300 of the skeleton 200 are both set upward under the restriction of the pin holder 42.

[0052] Subsequently, the second winding arm 5 winds one end of the winding segment of the copper wire around a group of pins 300 on the frame 200 , and cuts off the copper wire after winding. Then, the second winding arm 5 rises driven by the moving module 6 to make way for the first winding arm 4 .

[0053] Finally, the first winding arm 4 is turned over to the top of the frame 200, and drives the other end of the winding segment to be wound around another set of pins 300 of the frame 200, and the lead wire is cut off after the winding is completed. At this point, the frame 200 and the magnetic bar 100 are assembled.

[0054] In addition, the above-mentioned carrying part 3 is set to be multiple along the length direction of the first winding arm 4 on the base 1, and the first wire nozzle 41 and the second wire nozzle 51 are also set to be multiple corresponding to the carrying part 3 on the first winding arm 4 and the second winding arm 5, respectively, so that multiple magnetic bars 100 and skeletons 200 can perform winding operations at the same time.

[0055] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention.
