Technical Field
[0001] The present application relates to the field of inductance processing, and in particular to a winding mechanism for an inductance coil. Background Art
[0002] An inductor is a group of coaxial turns connected in series, made by winding enameled wire, yarn-covered wire or plastic-covered wire on an insulating frame, magnetic core or iron core. Its main function is to isolate and filter AC signals or to form a resonant circuit with capacitors, resistors, etc.
[0003] In the process of inductor processing, it is usually necessary to first wind the enameled wire into a coil, then transport the magnetic core to the coil through a feeding mechanism, and then assemble the coil on the magnetic core. The current winding mechanism of the inductor coil needs to cooperate with a clamping mechanism when winding the coil. The clamping mechanism is used to clamp one end of the enameled wire, and then the winding mechanism can wind the coil; and after the coil is wound, it also needs to cooperate with a shearing mechanism to cut off the root of the coil, so that the final finished coil can be obtained.
[0004] However, the additional provision of a clamping mechanism and a shearing mechanism not only makes the overall structure of the equipment more complicated, increasing the use cost and maintenance cost of the equipment, but also the independent clamping mechanism and shearing mechanism cannot achieve close coordination with the winding mechanism, greatly affecting the quality of the finished coil.

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.
[0033] See also Figure 1-3As shown, there is shown a winding mechanism for an inductor coil, which is used to wind an insulated wire into a coil, including a frame 1, a bearing seat 2 rotatable around its own axis and arranged on the frame 1, a first driving component 3 for driving the bearing seat 2 to rotate, a winding rod 4 movable along the horizontal and vertical directions and used to be buckled on the bearing seat 2 and wind the insulated wire, and a second driving component 5 for driving the winding rod 4 to move. The winding rod 4 is rotatable around its own axis, and a pressing unit 6 is also provided on the side of the bearing seat 2. The pressing unit 6 includes a pressing groove 61 opened on the top of the bearing seat 2, a movable pressing knife 62 that can be lifted and lowered and arranged in the pressing groove 61, a third driving component 63 for driving the movable pressing knife 62 to lift and lower, and a fixed pressing knife 64 arranged in the pressing groove 61, and the movable pressing knife 62 and the fixed pressing knife 64 are adjacent to each other and have blades on one side where the two are close to each other.
[0034] Through the cooperation of the dynamic pressure knife 62, the fixed pressure knife 64 and the pressure cutting groove 61, the insulated wire can be clamped during winding and sheared after winding, without the need to set up a clamping mechanism and a shearing mechanism separately. This not only simplifies the structure and reduces the use cost and maintenance cost of the equipment, but also the dynamic pressure knife 62, the fixed pressure knife 64 and the pressure cutting groove 61 arranged on the supporting seat 2 can cooperate closely with the supporting seat 2, thereby improving the quality of the finished coil.
[0035] Specifically, when winding the coil, the insulated wire is paid out through the pay-off wheel with the insulated wire wound thereon located above the side of the supporting seat 2, and the movable end of the insulated wire is clamped under the dynamic pressure knife 62. Then the winding rod 4 is buckled on the supporting seat 2 and rotates synchronously with the supporting seat 2. The insulated wire is wound on the winding rod 4 and forms a coil during the rotation of the supporting seat 2 and the winding rod 4. Then the dynamic pressure knife 62 rises and releases the clamping of the movable end. The winding rod 4 drives the coil to move and sends the connection between the coil and the insulated wire to the bottom of the dynamic pressure knife 62. The dynamic pressure knife 62 descends and cooperates with the fixed pressure knife 64 to cut the connection and then clamp the movable end of the insulated wire in the pressing groove 61. Then the winding rod 4 drives the cut coil to move to the unloading station. After the coil is unloaded, the winding rod 4 is reset and buckled on the supporting seat 2, and then the winding process starts again.
[0036] In this embodiment, combined with Figure 2 As shown, a bearing rod 7 for pressing the winding rod 4 is provided on the top of the bearing seat 2, and a pressure cutting groove 61 is located on one side of the bearing rod 7, which includes a first groove body 611 for accommodating a dynamic pressure knife 62, and a driving port (not shown in the figure) is opened at the bottom of the first groove body 611, and the output end of the third driving component 63 is passed through the driving port and connected to the dynamic pressure knife 62. Among them, the third driving component 63 is a cylinder, and the end of the piston rod of the cylinder is coaxially connected to the dynamic pressure knife 62.
[0037] The pressure cutting groove 61 further includes a second groove body 612 for accommodating the fixed pressure knife 64. The second groove body 612 is located on the side of the first groove body 611 away from the bearing rod 7. The bottom of the second groove body 612 has a first groove bottom wall 6121 that is inclined downward along the direction from the bearing rod 7 to the first groove body 611. The movable pressure knife 62 is attached to the first groove bottom wall 6121 and is movable along the extension direction of the first groove bottom wall 6121. A movable groove 641 is provided on one side of the fixed pressure knife 64 away from the blade. The extension direction of the movable groove 641 is consistent with the extension direction of the first groove bottom wall 6121. The pressure cutting unit 6 further includes a locking bolt 65 that is penetrated in the movable groove 641 and is threadedly connected to the first groove bottom wall 6121.
[0038] By providing the movable groove 641, when shearing the coil, the distance between the dynamic pressure knife 62 and the fixed pressure knife 64 can be adjusted according to the specific shearing needs, which greatly improves the shearing efficiency of the coil. Specifically, when adjusting, it is only necessary to loosen the locking bolt 65, and then move the fixed pressure knife 64 along the extension direction of the first groove bottom wall 6121, and the locking bolt 65 can move relative to the movable groove 641. After the fixed pressure knife 64 moves into place, tighten the locking bolt 65 to lock the fixed pressure knife 64 in the second groove body 612 again.
[0039] In this embodiment, combined with Figure 2 As shown, the side of the supporting seat 2 has an opening 19, one end of the second groove body 612 is connected to the first groove body 611, and the other end is connected to the opening 19, and the fixed pressure knife 64 is arranged on a side protruding from the opening 19 away from the dynamic pressure knife 62. In this way, the moving stroke of the fixed pressure knife 64 can be increased so that it can better cooperate with the dynamic pressure knife 62.
[0040] The pressing groove 61 also includes a third groove body 613 disposed between the first groove body 611 and the bearing rod 7. The bottom of the third groove body 613 has a second groove bottom wall 6131, and the second groove bottom wall 6131 is inclined downward from the bearing rod 7 to the first groove body 611. When the passive pressing knife 62 of the insulated wire is pressed downward, its main body can be supported on the inclined second groove bottom wall 6131, which effectively avoids excessive friction between the insulated wire and the side wall of the first groove body 611 during the pressing process of the passive pressing knife 62, thereby causing wear or breakage.
[0041] In this embodiment, the top of the bearing seat 2 has a bearing surface 21, which includes a first bearing surface 211 for opening the pressure cutting groove 61 and a second bearing surface 212 for setting the bearing rod 7. The first bearing surface 211 is arranged in the horizontal direction, and the second bearing surface 212 is inclined downward in a direction away from the first bearing surface 211. In this way, the inclined second bearing surface 212 can avoid the coil at the lower end of the winding rod 4 to prevent the two from interfering with each other during the rotation of the bearing seat 2.
[0042] The frame 1 is provided with a rotating seat 8, the bearing seat 2 is mounted on the rotating seat 8, and the output end of the first driving component 3 is connected to the rotating seat 8. The first driving component 3 is a motor, and the output shaft of the motor is coaxially connected to the rotating seat 8.
[0043] In this embodiment, combined with Figure 1 and Figure 3 As shown, the winding mechanism also includes a base 9 arranged on the frame 1, a first slide 10 arranged on the base 9 slidable in the horizontal direction, a second slide 11 arranged on the first slide 10 slidable in the vertical direction, and a winding seat 12 arranged on the second slide 11. The second driving component 5 includes a driving component a51 for driving the first slide 10 to move, and a driving component b52 for driving the second slide 11 to move. The winding rod 4 is rotatable around its own axis and is arranged in the winding seat 12. The winding mechanism also includes a fourth driving component 13 for driving the winding rod 4 to rotate. Among them, the driving component a51 and the driving component b52 are both motor screw structures.
[0044] A first guide rail 14 is disposed on the base 9 , a second guide rail 15 is disposed on the first slide 10 , the first slide 10 is slidably connected to the first guide rail 14 , and the second slide 11 is slidably connected to the second guide rail 15 .
[0045] The winding mechanism also includes a stripping cylinder 16 disposed on the side of the winding seat 12. The piston rod of the stripping cylinder 16 is retracted in the vertical direction and a stripping plate 17 is connected to its end. A stripping groove 18 is provided on the stripping plate 17, and the stripping groove 18 surrounds the lower end of the winding rod 4. Among them, a driving seat 20 is provided at the end of the piston rod of the stripping cylinder 16, and the stripping plate 17 is connected to the side of the driving seat 20. After the coil is wound, the stripping groove 18 surrounding the lower end of the winding rod 4 can move downward under the drive of the stripping cylinder 16, and the groove wall on its side can resist the two ends of the coil and bring the coil away from the winding rod 4, which greatly facilitates the separation of the coil from the winding rod 4.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
