Description

Technical Field

[0002] The winding machine is a fully automated or semi-automated processing equipment used to wind the enameled copper wire around the outside of the magnetic ring to form a common-mode inductor coil. Depending on the different functions of the common-mode inductor coil, the winding method and number of winding turns for the external copper wire are different. The winding machines on the market now generally use the rotating magnetic ring to achieve the winding of the wire on the magnetic ring. This winding method causes the wire to be unevenly arranged and cross-overlapped during the winding process. If the winding method is replaced with a magnetic ring that does not move, the wire is wound around the outside of the magnetic ring, and it rotates with each winding, this method will greatly improve the processing quality of the coil, and the arrangement density of the coil can be adjusted. However, the hooking device of the traditional winding machine cannot rotate with the winding and rotation of the wire, so it is impossible to complete the hooking operation when the magnetic ring is stationary.

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] See also Figure 1-Figure 6, is a wire hooking device 100 provided by the utility model. The wire hooking device 100 provided by the utility model is suitable for use on various winding machines. It is used to hook the wire located above the magnetic ring during the winding operation of the winding machine, pass through the through hole in the center of the magnetic ring, and pull it to the bottom of the magnetic ring to complete the winding of the wire inside the magnetic ring. The wire hooking device 100 provided by the utility model can better hook the wire, and is suitable for the wire hooking operation when the magnetic ring rotates, and is also suitable for the wire hooking operation when the magnetic ring does not rotate.

[0032] like Figure 1 and Figure 2 FIG. 1 is a schematic diagram of the three-dimensional structure of the line hooking device 100 provided by the utility model. Figure 1 , is a schematic diagram of the three-dimensional structure of the wire hooking device 100 in the initial state and at the lowest position of the winding machine. Figure 2 , which is a schematic diagram of the three-dimensional structure of the wire hooking device 100 when it is in the wire hooking state and at the highest position of the winding machine. The wire hooking device 100 provided by the utility model includes a mounting bracket 10, a lifting drive assembly 20 arranged on the mounting bracket, a translation assembly 30 driven by the lifting drive assembly 20, and a hook assembly 40 fixedly connected to the translation assembly 30. The mounting bracket 10 in the wire hooking device 100 is arranged at the bottom of the frame of the winding machine to support the entire lifting drive assembly 20. The lifting drive assembly 20 is used to drive the translation assembly 30 and the hook assembly 40 fixed thereon to lift and reciprocate in the vertical direction, that is, Figure 1 and Figure 2 The translation assembly 30 is arranged on the lifting drive assembly 20, and is used to drive the entire hook assembly 40 to move horizontally in the horizontal direction. The setting of the translation assembly 30 is to compensate for the fact that after the hook assembly 40 rotates horizontally, the center of the hook body of the hook 41 in the hook assembly 40 is always located at the central axis of the magnetic ring. Because the center of the hook body of the commercially available hook 41 is not concentric with the center of the hook 41 as a whole, the center of the hook body can be coaxially arranged with the center of the magnetic ring in the initial position. However, after the hook 41 is driven to rotate, the center of the hook body will be horizontally offset from the center of the magnetic ring as it rotates. Therefore, the translation assembly 30 in the hooking device 100 provided by the utility model is to compensate for the displacement of the above-mentioned center offset, so as to ensure that after each rotation, the center of the hook body of the hook 41 is always coaxially arranged with the center of the magnetic ring, thereby ensuring that the hook 41 can smoothly hook the wire above the magnetic ring every time it rises to the highest point. The hook assembly 40 in the thread hooking device 100 is used to fix the hook 41, drive the hook 41 to rotate, and detect whether the hook 41 hooks the wire, so as to ensure the smooth progress of the thread hooking operation.

[0033] Specifically, Figure 3As shown, the translation assembly 30 in the hooking device 100 provided by the utility model includes a fixed plate 31 fixed to the lifting drive assembly 20, a translation plate 32 fixedly connected to the hook needle assembly 40, and a horizontal driving member 33 driving the translation plate 32 to move horizontally relative to the fixed plate 31. The horizontal driving member 33 drives the translation plate 32 to which the hook needle assembly 40 is fixed to move horizontally relative to the fixed plate 31, so that the center of the hook body of the hook needle 41 of the hook needle assembly 40 is always on the same vertical axis as the center of the magnetic ring in the winding machine after the hook needle assembly 40 rotates. And, as Figure 3 As shown, the translation plate 32 of the translation assembly 30 is provided with an L-shaped connection block 321, and the fixed plate 31 is provided with two spaced-apart limit blocks 311 in the moving direction of the translation plate 32, and one end of the L-shaped connection block 321 extends between the two limit blocks 311. The two limit blocks 311 limit the horizontal movement distance of the translation plate 32 in the horizontal direction. In addition, a sensor can be provided on the limit block 311 to confirm the translation amount of the hook assembly 40 each time.

[0034] Furthermore, if Figure 4-6 As shown, it is a structural schematic diagram of the hook assembly 40 in the hooking device 100 provided by the utility model. The hook assembly 40 includes a hook 41, a vertical mounting plate 46 fixed to the translation assembly 30, a rotating platform 42 fixed on the vertical mounting plate 46, a mounting seat 43 arranged on the rotating platform 42, and a movable seat 44 that can be lifted and lowered and arranged on the mounting seat 43, and the hook 41 is fixed on the top of the movable seat 44. The top of the hook 41 in the hook assembly 40 is a hook body, which is used to hook the wire and pull the wire from the top of the magnetic ring through the magnetic ring to the bottom of the magnetic ring. The rotating platform 42 is used to drive all the components above it to realize horizontal rotation, thereby driving the hook body 41 to realize horizontal rotation. The hook body 41 can rotate horizontally, that is, it is suitable for use in a winding machine in which the magnetic ring is stationary and the winding device is rotating. It can better cooperate with the winding device in the winding machine to realize the winding of the wire on the magnetic ring, control the uniformity of the arrangement of the coil on the magnetic ring, and reduce the occurrence of the wire crossing on the magnetic ring. The relative movement of the mounting seat 43 and the movable seat 44 in the hook assembly 40 in the vertical direction can be used to identify whether the hook 41 hooks the wire. When it is identified that the hook fails to hook the wire, timely measures can be taken to stop the movement of the wire hooking device 100, which can also facilitate the staff to identify faults in the wire hooking device 100.

[0035] Furthermore, the rotating platform 42 in the hook assembly 40 provided by the utility model includes a rotating driving member 421 fixed to the bottom of the vertical mounting plate 46 and a turntable 422 driven by the rotating driving member 421 to rotate horizontally. In this embodiment, the rotating driving member 421 is a driving motor and a reducer. Driven by the reducer, the turntable 422 rotates horizontally around the central axis, driving the mounting seat 43, the movable seat 44 and the hook 41 thereon to rotate horizontally, so that the hook portion of the hook 41 can rotate synchronously with the rotation of the wire.

[0036] Specifically, the hook assembly 40 in the hooking device 100 provided by the utility model also includes a detection assembly 45 for detecting whether the hook 41 hooks the thread. The detection assembly 45 is used in conjunction with the mounting seat 43 and the movable seat 44 in the hook assembly 40. Among them, the detection assembly 45 includes a sensing piece 451 that can be raised and lowered with the movable seat 44 and a sensor 452 fixed on the vertical mounting plate 46 for detecting the movement of the sensing piece 451. The sensor 452 is fixed on the vertical mounting plate 46, and the vertical mounting plate 46 and the mounting seat 43 are both in a relatively fixed state, that is, the mounting seat 43 and the vertical mounting plate 46 are always at the same horizontal position. The sensing piece 451 is fixed on the movable seat 44, and the movable seat 44 can be raised and lowered relative to the mounting seat 43. Therefore, the sensing piece 451 will rise and fall relative to the vertical mounting plate 46 as the movable seat 44 rises and falls, so the sensor 452 can detect the movement of the sensing piece 451 and sense whether the hook 41 hooks the wire.

[0037] In the actual hooking operation process, the lifting drive assembly 20 drives the hook needle assembly 40 to move upward from the lowest point of the initial position to the highest point of the hooking position. During the upward movement, the hook needle 41 passes through the central through hole of the magnetic ring. Then, the hook needle assembly 40 is driven to move downward. During the downward movement, after the hook body of the hook needle 41 hooks the wire, the wire will exert an upward pulling force on the hook body. At this time, the hook needle 41 will move upward. At this time, the mounting seat 43 moves downward with the lifting drive assembly 20, and the movable seat 44 moves upward with the wire hooked by the hook needle 41, so that the movable seat 44 and the mounting seat 43 are relatively moved in the vertical direction, and then the sensor sheet 451 fixedly connected to the movable seat 44 and the sensor 452 fixedly connected to the vertical mounting plate 46 are relatively moved in the vertical direction, so the sensor 452 receives the signal output to confirm that the hook needle 41 has hooked the wire. If the hook 41 does not hook the wire, the hook 41 will move downward along with the lifting drive assembly 20. At this time, there is no relative movement between the sensor sheet 451 and the sensor 452. Therefore, the sensor 452 has no signal output, confirming that the hook 42 has not hooked the wire.

[0038] like Figure 4 and Figure 6 As shown, the mounting seat 43 of the hook assembly 40 provided by the utility model includes a vertical support plate 431 fixed on the rotating platform 42 and a horizontal support plate 432 fixed above the vertical support plate 431. The vertical support plate 431 is directly fixed on the turntable 422 of the rotating platform 42, so that the mounting seat 43 can rotate horizontally with the rotating platform 42. The vertical support plate 431 is fixed to the top of the vertical support plate 431, and is used to limit the relative range of motion of the movable seat 44. The horizontal support plate 432 is provided with an opening 4321 for the movable seat 44 to pass through. The movable seat 44 of the hook assembly 40 is a T-shaped structure, including a horizontal portion 441 and a vertical portion 442 arranged perpendicularly to each other, the horizontal portion 441 is arranged between the horizontal support plate 432 of the mounting seat 43 and the rotating platform 42, and the vertical portion 442 extends upward through the opening 4321 of the horizontal support plate 432. A slide rail is provided between the vertical portion 442 of the movable seat 44 and the vertical support plate 431 of the mounting seat 43, so that the vertical portion 442 of the movable seat 44 can be movably connected with the vertical support plate 431 and can be relatively vertically lifted and lowered. The vertical portion 442 of the movable seat 44 extends upward from the opening 4321 of the horizontal support plate 432 of the mounting seat 43 and is fixedly connected with the main body of the hook 41, and is movably connected with the induction sheet 451 of the detection assembly 45, that is, the induction sheet 451 can be lifted and lowered vertically along with the movable seat 44, but the induction sheet 451 will not limit the rotation of the movable seat 44 in the horizontal direction.

[0039] Specifically, Figure 4-6 As shown, in the hook assembly 40 provided by the utility model, a circle of grooves 4421 for the induction sheet 451 to be embedded is provided on the vertical portion 442 of the movable seat 44, and a notch that can be embedded in the groove 4421 of the movable seat 44 is provided on the end of the induction sheet 451 connected to the movable seat 44, and the notch of the induction sheet 451 is embedded in the groove 4421, so that the movable seat 44 can rotate horizontally relative to the induction sheet 451. The notch of the induction sheet 451 is embedded in the groove 4421 provided on the vertical portion 442 of the movable seat 44, so that the movable seat 44 can drive the induction sheet 451 to rise and fall vertically, but when the movable seat 44 rotates horizontally, the induction sheet 451 is in the groove 4421 of the movable seat 44, and will not hinder the horizontal rotation of the movable seat 44.

[0040] Furthermore, if Figure 5As shown, the hook assembly 40 provided by the utility model further includes a spring 47 disposed between the horizontal support plate 432 of the mounting seat 43 and the horizontal portion 441 of the movable seat 44. In the initial state, the spring 47 is in an open state, and the bottom of the horizontal portion 441 of the movable seat 44 abuts against the rotating platform 42. When the hook 41 hooks the wire, causing the movable seat 44 to move relative to the mounting seat 43, the horizontal portion 441 of the movable seat 44 presses the spring 47, causing the bottom of the horizontal portion 441 to separate from the rotating platform 42, resulting in a phenomenon as shown in FIG. Figure 5 When the hook 41 is separated from the wire, the force pulling the hook 41 upward disappears, and the spring 47 restores the horizontal portion 441 of the movable seat 44 to the initial state, pushing the movable seat 44 to move downward and return to the initial position.

[0041] The hook needle assembly 40 of a wire hooking device 100 provided by the utility model includes a rotating platform 42, so that the rotating platform 42 can drive the hook needle 41 to rotate in the horizontal direction to ensure that the hook body of the hook needle 41 can be consistent with the rotation direction of the wire on the winding machine. During each coil winding process, the wire can be hooked and the wire can be pulled from the top of the magnetic ring through the through hole of the magnetic ring to the bottom of the magnetic ring to complete the wire hooking operation, thereby controlling the tightness of the wire on the magnetic ring when it is wound into a coil, so that the arrangement of the coil is more uniform, thereby improving the product quality of the processed common mode inductor.

[0042] The utility model also provides a winding machine, including the above-mentioned wire hooking device 100 and a winding device, a magnetic ring clamping device, a wire feeding device, and a loading and unloading device. The wire hooking device 100 cooperates with the winding device and the magnetic ring clamping device in the winding machine to realize the winding of the wire inside and outside the magnetic ring.

[0043] When the magnetic ring clamping device of the winding machine is a fixed and non-rotating structure, the magnetic ring clamped on the magnetic ring clamping device does not rotate, and the wire hooking device 100 provided by the utility model will be synchronized with the winding device, and as the winding device rotates horizontally relative to the magnetic ring, the coil is wound in a manner that the magnetic ring does not rotate but the wire rotates.

[0044] When the magnetic ring clamping device of the winding machine is a rotating structure, the magnetic ring clamping device drives the magnetic ring to rotate around the center of the magnetic ring. The wire hooking device 100 provided by the utility model will cooperate with the winding device in the vertical direction to realize the rotation of the magnetic ring and complete the winding of the coil in a way that the wire does not rotate.

[0045] The utility model provides a winding machine which adopts the above-mentioned wire hooking device 100 and is suitable for the automated winding processing of common mode inductors with different winding methods. It can be suitable for the wire hooking operation in the winding method in which the magnetic ring rotates and the wire is fixedly wound, and it can also be suitable for the wire hooking operation in the winding method in which the magnetic ring does not rotate and the wire rotates.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
