Description

Technical Field

[0001] The present invention relates to the technical field of inductance winding equipment, and particularly relates to an inductance winding machine and a winding method. Background Art

[0002] In the production and manufacturing of inductance coils, winding a copper wire around a magnetic ring is a key process. The traditional winding method is to completely rely on a crochet needle to pull the unwound wire from above the magnetic ring to below. This method has the following drawbacks:

[0003] 1. Because for each turn of winding, the crochet needle has to rub against the entire length of the unwound wire, the wire is severely worn.

[0004] 2. After the unwound wire is pulled down by the crochet needle, the wire tail is in a free hanging state without any other constraints, and it is very easy to deform and bend, and its position is uncontrollable. The longer the wire, the more difficult it is to control the position of its tail, and it is easy to wind into other structural parts of the winding equipment, causing problems such as wire breakage and damage to the insulation layer of the wire.

[0005] Therefore, how to store the longer and unwound copper wire during the winding of the inductance, control the position of the wire tail, and how to reduce the wear of the wire tail part during the winding process have become urgent technical problems to be solved. Summary of the Invention

[0006] The present invention provides an inductance winding machine and a winding method for the existing technical problems.

The wire feeding device is used to convey the wire to one end of the magnetic ring. The crochet needle device is used to hook the wire from one end of the magnetic ring to the other end of the magnetic ring. The winding device is used to clamp the wire and wind the wire around the magnetic ring. The wire arranging device is used to clamp the magnetic ring and drive the magnetic ring to rotate around its axis. The wire storage device is used to store the wire with a wire tail.

[0008] Based on the above technical solutions, the present invention can also be improved as follows:

[0009] Preferably, it further includes a magnetic ring feeding device. The magnetic ring feeding device includes a first cylinder, a second cylinder, an optical fiber, an optical fiber sensor, and a magnetic ring conveying channel. The magnetic ring conveying channel is used to store and convey the magnetic ring.

The wire hook is arranged outside the inner support ring and is used to hook the wire within its hooking range and wind the wire around the inner support ring.

[0016] Preferably, an outer baffle is arranged outside the inner support ring. The outer baffle is arc-shaped and is provided with an opening for hooking the wire.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0054] It should be noted that the terms "first", "second", etc. in the description, claims and the above-mentioned drawings of the present invention are used to distinguish similar objects and do not necessarily describe a specific order or sequence. The orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0055] Referring to Figures 1 to 20 As shown, the present invention discloses an inductor winding machine, which includes a first winding mechanism. The first winding mechanism is installed on a frame, and a control panel and an electrical box are installed on the frame for convenient control of each device. The first winding mechanism includes a wire feeding device 300, a winding device 400, a crochet device 500, a wire arranging device 600 and a wire storage device 700. The wire feeding device 300 is used to convey the wire to one end of the magnetic ring 109. The crochet device 500 is used to hook the wire from one end of the magnetic ring 109 to the other end of the magnetic ring 109. The winding device 400 is used to clamp the wire and wind the wire around the magnetic ring 109. The wire arranging device 600 is used to clamp the magnetic ring 109 and drive the magnetic ring 109 to rotate around its axis; the wire storage device 700 is used to store the wire with a wire tail. The wire can be a winding wire such as copper wire, aluminum wire or copper-clad aluminum wire, and the shape of the magnetic ring 109 can be a circular magnetic ring or a rectangular magnetic ring.

[0056] Referring to Figure 2As shown, the inductor winding machine further includes a magnetic ring feeding device 100. The magnetic ring feeding device 100 includes a first cylinder 104, a second cylinder 105, an optical fiber 106, an optical fiber sensor 107, and a magnetic ring conveying channel. The magnetic ring conveying channel is used to store and convey magnetic rings 109. At the end of the magnetic ring conveying channel, the first cylinder 104, the second cylinder 105, the optical fiber 106, and the optical fiber sensor 107 are installed. The first cylinder 104 is used to make the magnetic rings 109 enter the specified position one by one. The second cylinder 105 is used to restrict the magnetic ring 109 to be wound at the specified position. The optical fiber 106 and the optical fiber sensor 107 cooperate to detect whether there is a magnetic ring 109 at the specified position. Specifically, the magnetic ring conveying channel includes a material pipe 108, a first cover plate 102, and a second cover plate 103. The material pipe 108 is an inclined transparent pipe, which is convenient for observing the state of the magnetic ring 109 and enables the magnetic ring 109 to slide down under the action of gravity. The first cover plate 102 and the second cover plate 103 are installed at the lower end of the material pipe 108. The first cover plate 102 and the second cover plate 103 are installed on the fixed plate 101. The first cover plate 102 and the second cover plate 103 cooperate to form a slideway for the magnetic ring 109 to pass through. There is a gap between the first cover plate 102 and the second cover plate 103, which is convenient for observing the state of the magnetic ring. The end of the slideway is a horizontally arranged specified position for the magnetic ring. The first cylinder 104 is located on one side of the specified position, and the second cylinder 105 is located on the other side of the specified position. The output end of the first cylinder 104 is used to block other magnetic rings 109, so that there is only one magnetic ring 109 at the specified position. The output end of the second cylinder 105 is used to block the magnetic ring 109 at the specified position to prevent it from falling. When it is necessary to take away the magnetic ring 109 at the specified position, the output end of the second cylinder 105 retracts to avoid. After the magnetic ring 109 is taken away, the first cylinder 104 and the second cylinder 105 reset, so that another magnetic ring 109 moves to the bottom specified position, realizing the automatic feeding of the magnetic ring 109.

[0057] Refer to Figure 3 As shown, the inductor winding machine further includes a magnetic ring loading device 200. The magnetic ring loading device 200 is used to convey the magnetic rings 109 at the magnetic ring feeding device 100 to the wire arranging device 600 to realize the transfer of the magnetic rings 109.

[0058] Specifically, the magnetic ring loading device 200 includes a first support plate 202 and a first driving motor 201 mounted on the first support plate 202. Two first synchronous belt pulleys 203 are mounted on the first support plate 202. The two first synchronous belt pulleys 203 are connected by a first synchronous belt 204. The output end of the first driving motor 201 is connected to one of the first synchronous belt pulleys 203. A slider 205 is mounted on the first synchronous belt 204. The slider 205 is connected to a third cylinder 208 through a first connecting plate 207. The third cylinder 208 is used to control the magnetic ring gripper 209 to grab the magnetic ring 109 of the magnetic ring feeding device 100 to the wire arranging device 600, realizing the transfer of the magnetic ring 109.

[0059] Further, the slider 205 moves along the linear guide rail 206 driven by the first synchronous belt 204. The linear guide rail 206 is mounted on the first support plate 202. A stop block 210 is mounted at the end of the linear guide rail 206 for restricting the moving distance of the slider 205. The linear guide rail 206 can increase the smoothness during the transfer of the magnetic ring 109, facilitating the smooth transfer of the magnetic ring 109.

[0060] Refer to Figure 4 As shown in the figure, in this embodiment, the online device 300 includes a fourth cylinder 301, a wire pressing clamp 302, a wire conduit 303 and a wire end clamp 304. The fourth cylinder 301 is used to drive the wire pressing clamp 302 and the wire conduit 303 to move reciprocally and convey the wire end to the wire end clamp 304. The wire end clamp 304 is used to clamp or release the wire end conveyed by the wire conduit 303.

[0061] The wire pressing clamp 302 is used to clamp or release the wire. The wire conduit 303 plays a role in supporting, positioning and leveling the wire, facilitating the wire end clamp 304 to pick up the wire end of the wire and enabling the wire to move along the wire conduit 303, reducing the occurrence of wire bending and knotting.

[0062] Refer to Figure 5 As shown in the figure, in this embodiment, the winding device 400 includes a swinging assembly, a swing arm 406 and a wire clamping claw 407. The swing arm 406 is connected to the wire clamping claw 407. The wire clamping claw 407 is used to clamp or release the wire. The swinging assembly is used to drive the swing arm 406 and the wire clamping claw 407 to perform an arc-shaped winding action.

[0063] Specifically, the swinging assembly includes a second support plate 401, a second driving motor 402, a second synchronous belt pulley 403 and a third synchronous belt pulley 404. The output end of the second driving motor 402 passes through the second support plate 401 and is connected to the second synchronous belt pulley 403. The second synchronous belt pulley 403 is connected to the third synchronous belt pulley 404 through a second synchronous belt 405. One end of the swing arm 406 is hinged to the second synchronous belt pulley 403, and the other end of the swing arm 406 is hinged to the third synchronous belt pulley 404.

[0064] Further, a plurality of through holes are circumferentially provided on the second synchronous pulley 403 and the third synchronous pulley 404. The swing arm 406 is hinged to the through holes through a swing shaft, so as to drive the wire clamping claw 407 to perform an arc-shaped wire winding action.

[0065] When the second driving motor 402 works, it drives the second synchronous pulley 403 and the third synchronous pulley 404 to rotate. Since the rotating shafts at both ends of the swing arm 406 are located on one side of the rotating shafts of the second synchronous pulley 403 and the third synchronous pulley 404 itself and have the same phase, when the second synchronous pulley 403 and the third synchronous pulley 404 rotate, they can drive the swing arm 406 and the wire clamping claw 407 to swing in an arc, complete the wire winding action, and improve the wire winding efficiency.

[0066] Further, the wire winding device 400 further includes a wire dial 408 and a third driving motor 409. The wire dial 408 is located below the wire clamping claw 407. A plurality of wire dial holes are circumferentially provided on the wire dial 408. The wire dial 408 is connected to the output end of the third driving motor 409 and rotates under the drive of the third driving motor 409, so that different wire dial holes are located below the wire clamping claw 407. The wire clamping claw 407 clamps the wire between the magnetic ring 109 and the wire dial 408 above the magnetic ring 109 to complete the wire winding action. The wire dial holes of the wire dial 408 play a role in separating the wire, avoiding the situation of the wire itself being wound and knotted, and ensuring the smoothness of the wire winding.

[0067] Refer to Figures 6 to 8 As shown, in this embodiment, the crochet device 500 includes a fourth driving motor 501 and a crochet hook 503. The fourth driving motor 501 drives the crochet hook 503 to rotate. The crochet hook 503 is installed on the X-direction adjusting plate 504 through a fixed seat 502 and can move along the X-direction adjusting plate 504 to adjust the position of the crochet hook 503 in the X direction. The X-direction adjusting plate 504 is installed on the Y-direction adjusting plate 505. The Y-direction adjusting plate 505 is installed on the connecting plate two 508 through a sliding groove to realize the adjustment of the position of the crochet hook 503 in the Y direction. The connecting plate two 508 is slidably installed on the Z-direction slide rail 507 and moves up and down along the Z-direction slide rail 507 under the drive of the fifth driving motor 506, thereby driving the crochet hook 503 to move up and down. By driving the crochet hook 503 to move up and down, rotate and move, it is ensured that the crochet hook 503 can normally hook the wire, realizing automatic wire hooking and wire retracting.

[0068] Further, a guiding portion is provided on one side of the upper part of the crochet hook 503, and the guiding portion is arranged obliquely and straddles the central axis of the crochet hook 503. The inclination angle α of the guiding portion is 30°-70°. By providing the guiding portion, the highest point of the crochet hook 503 deviates from the center line. When there is a small positional deviation of the wire, the crochet hook is deformed, or there is a deviation in the debugging position, the wire is guided by the guiding portion so that all the wires are on the same side of the crochet hook 503, ensuring that the crochet hook 503 hooks the wire stably and accurately, making the production process have better fault tolerance, greatly improving the stability and continuity of production, and improving the working efficiency of the winding machine.

[0069] Referring to Figure 9 As shown, in this embodiment, the wire arranging device 600 includes a sixth driving motor 601, a rotating shaft 603, and a second magnetic ring jaw 609. The sixth driving motor 601 is used to drive the rotating shaft 603 to rotate. The rotating shaft 603 drives the magnetic ring 109 clamped by the second magnetic ring jaw 609 to rotate around its own axis through a connecting component. The second magnetic ring jaw 609 is installed on the first clamping cylinder 608.

[0070] Specifically, the connecting component includes a third connecting plate 605 and a support seat 606. The output end of the sixth driving motor 601 is connected to the fourth synchronous belt pulley 602 through a synchronous belt. The fourth synchronous belt pulley 602 is connected to the rotating shaft 603. The rotating shaft 603 is rotatably installed on the bearing seat 604 through a bearing. The rotating shaft 603 passes through the bearing seat 604 and is connected to the third connecting plate 605. The bearing seat 604 is installed on the machine frame. The third connecting plate 605 is connected to the support seat 606. The third connecting plate 605 and the support seat 606 are integrally L-shaped. When the sixth driving motor 601 works, it drives the fourth synchronous belt pulley 602 and the rotating shaft 603 to rotate. The rotating shaft 603 drives the third connecting plate 605 and the support seat 606 to rotate around the bearing seat 604. Since the magnetic ring 109 is coaxially arranged with the rotating shaft 603, the magnetic ring 109 is driven to rotate around its axis. During the winding process, for each wire wound on the magnetic ring 109, the sixth driving motor 601 drives the magnetic ring 109 to rotate by an angle, so as to realize the uniform arrangement of the wire on the magnetic ring 109 as required, ensure the quality of the magnetic ring induction coil, and improve the winding efficiency.

[0071] Further, a rotating cylinder 607 is installed on the support seat 606, and the output end of the rotating cylinder 607 is connected to the first clamping cylinder 608. The rotating cylinder 607 can drive the first clamping cylinder 608 to rotate by 180°, thereby driving the magnetic ring 109 to flip, meeting the requirement of reverse winding on the magnetic ring 109 and improving the applicable range of the wire arranging mechanism.

[0072] The inductor winding machine includes a wire head clamping assembly, which includes a first wire head clamping assembly and a second wire head clamping assembly. The second wire head clamping assembly is used to clamp the wire head formed by the first section of the coil. The second wire head clamping assembly includes a second wire head clamp 613, a second wire head clamping cylinder 614, a horizontal movement cylinder 615 and a lifting cylinder 616. The lifting cylinder 616 is installed on the third connecting plate 605. The output end of the lifting cylinder 616 is installed with the horizontal movement cylinder 615. The output end of the horizontal movement cylinder 615 is installed with the second wire head clamping cylinder 614. The second wire head clamping cylinder 614 is installed with the second wire head clamp 613. The second wire head clamping cylinder 614 drives the second wire head clamp 613 to loosen or clamp the wire head. The horizontal movement cylinder 615 drives the second wire head clamp 613 to move in the horizontal direction to adjust the horizontal position of the second wire head clamp 613. The lifting cylinder 616 drives the second wire head clamp 613 to lift and lower to adjust the height of the second wire head clamp 613, so as to meet the clamping requirements of wire heads with different lengths or different positions and improve the convenience of use.

[0073] The first wire head clamping assembly is used to clamp the two wire heads formed by the first coil. The two first wire head clamping assemblies are arranged on both sides of the magnetic ring 109. The first wire head clamping assembly is connected to the output end of the rotary cylinder 607. When the rotary cylinder 607 drives the magnetic ring 109 to flip 180°, it can drive the first wire head clamping assembly to flip synchronously, always maintaining the clamping state of the wire head, avoiding the wire head from being wound into the coil being wound, and ensuring that the coil can be wound normally.

[0074] In this embodiment, the first wire head clamping assembly includes a first wire head clamp 610, a first wire head clamping cylinder 611 and a fifth cylinder 612. Specifically, the fifth cylinder 612 is installed at the output end of the rotary cylinder 607. The output end of the fifth cylinder 612 is connected to the first wire head clamping cylinder 611. The first wire head clamping cylinder 611 is provided with the first wire head clamp 610. The first wire head clamping cylinder 611 drives the first wire head clamp 610 to clamp or loosen the wire head. The fifth cylinder 612 drives the first wire head clamping cylinder 611 and the first wire head clamp 610 to move, so as to meet the clamping requirements of wire heads with different lengths and different positions and improve the convenience of use.

[0075] Refer to Figure 10 As shown, in this embodiment, the wire storage device 700 includes a seventh drive motor 701, an inner support ring 702 and a wire hook 704. The seventh drive motor 701 is used to drive the inner support ring 702 to rotate. The wire hook 704 is arranged outside the inner support ring 702. The wire hook 704 is used to hook the wire within its hooking range and wind the wire around the inner support ring 702.

[0076] Further, an outer baffle 703 is provided on the outer side of the inner support ring 702. The outer baffle 703 is installed on the frame. The outer baffle 703 is arc-shaped, and an opening for hooking the wire is provided on the outer baffle 703. An upper support plate 705 is installed at the upper end of the inner support ring 702, and a lower support plate 706 is installed at the lower end. The inner support ring 702, the outer baffle 703, the upper support plate 705, and the lower support plate 706 cooperate to form a space for accommodating the wire, so as to store the wire, control the position of the wire, and solve the problem that the wire is wound into other devices and damages the insulating layer of the wire.

[0077] During use, the wire hook 704 on the outer side of the inner support ring 702 makes a circular motion as the inner support ring 702 rotates, hooks the wire that has already been at the opening of the outer baffle 703. As the seventh drive motor 701 drives the inner support ring 702 to continue rotating, since the tail end (i.e., the wire tail) of the copper wire is in a free state, the wire tail is continuously wound around the inner support ring 702 under the pulling of the wire hook 704 until all the remaining wire is wound around the inner support ring 702. The wire is stored in the wire accommodating space between the inner support ring 702 and the outer baffle 703, so the situation of winding into other devices will no longer occur, ensuring the safety of the winding process. The controllability of the wire tail position enables this solution to meet the winding requirements of longer wires.

[0078] In this embodiment, the inductor winding machine further includes a second winding mechanism and an intermediate handling device 800. The first winding mechanism is used to wind the first coil on the magnetic ring, the second winding mechanism is used to wind the second coil on the magnetic ring, and the intermediate handling device 800 is used to convey the magnetic ring 109 from the first winding mechanism to the second winding mechanism. The intermediate handling device 800 is located between the first winding mechanism and the second winding mechanism. The intermediate handling device 800 includes a handling jaw 801, a handling cylinder 802, and a turntable 803. The handling jaw 801 is installed at the output end of the handling cylinder 802, the handling cylinder 802 is installed on the turntable 803, the handling cylinder 802 drives the handling jaw 801 to move back and forth, and the turntable 803 drives the handling cylinder 802 and the handling jaw 801 to rotate. By setting the first winding mechanism and the second winding mechanism, a butterfly coil is wound on the magnetic ring. The second winding mechanism and the first winding mechanism are symmetrically arranged on the frame. The first winding mechanism includes a second wire head clamping assembly. The second winding mechanism includes a first wire head clamping assembly and a second wire head clamping assembly. The rest of the structure of the second winding mechanism is the same as that of the first winding mechanism, and will not be described in detail here. After the second winding mechanism finishes winding, the wound magnetic ring is removed by the blanking device 900. The structure of the blanking device 900 is the same as that of the magnetic ring loading device 200, and will not be described in detail here.

[0079] A wire cutting device 1000 is provided on one side of both the first winding mechanism and the second winding mechanism to facilitate wire cutting.

[0080] The present invention also discloses an inductor winding method, which uses the inductor winding machine as described above. The specific steps are as follows:

[0081] Step S1: The wire feeding device 300 continuously feeds the wire. The wire with a wire tail is continuously stored on the wire storage device 700. When the wire feeding device 300 has fed the wire of length L / 2, the wire feeding is stopped and the wire is clamped.

[0082] Step S2: The crochet device 500 hooks the wire from one end of the magnetic ring 109 to the other end of the magnetic ring 109. The winding device 400 clamps the wire and winds the wire around the magnetic ring 109. For each turn of the wire wound, the wire arranging device 600 drives the magnetic ring 109 to rotate a certain angle. Repeat this step until the wire of length L / 2 is wound.

[0083] Step S3: The magnetic ring 109 is flipped. The wire is horizontally placed on the inner hole of the magnetic ring 109, and the wire head clamping assembly clamps the wire head.

[0084] Step S4: The crochet device 500 hooks the wire from one end of the magnetic ring 109 to the other end of the magnetic ring 109 again. The wire feeding device 300 continues to feed the wire, and the wire storage device 700 continues to store the wire. When the wire feeding device 300 has fed the wire of length L / 2 again, the wire feeding is stopped and the wire is cut to form a new wire head. The wire storage device 700 stores the wire with the wire head.

[0085] Step S5: The winding device 400 clamps the wire and winds the wire around the magnetic ring 109. The crochet device 500 hooks the wire from one end of the magnetic ring 109 to the other end of the magnetic ring 109. Repeat this step until all the wires are wound.

[0086] Taking the total length of the wire used for winding the first coil a on the magnetic ring 109 as L1 and the total length of the wire used for winding the second coil b as L2 as an example, with reference to Figures 12 to 20 As shown, the specific winding method of the inductor winding machine of the present invention is as follows:

[0087] Loading of the magnetic ring 109:

[0088] The magnetic ring loading device 200 transports the magnetic ring 109 at the magnetic ring feeding device 100 to the magnetic ring jaw two 609 of the wire arranging device 600.

[0089] Wire feeding:

[0090] The fourth cylinder 301 works, driving the wire conduit 303 to convey the wire head to the wire head clamp 304. The wire head clamp 304 clamps the wire head. Subsequently, the fourth cylinder 301 drives the wire conduit 303 to retreat, avoiding the position above the magnetic ring 109.

[0091] Wire hooking:

[0092] The crochet hook 503 moves in the direction of the magnetic ring 109. In this embodiment, the crochet hook 503 moves upward, passes through one of the wire guiding holes and the inner hole of the magnetic ring 109, and rotates a certain angle, such as 90°, so that the hook on the crochet hook 503 can hook the wire. Subsequently, the crochet hook 503 moves downward to pull the wire to the other end of the magnetic ring 109, that is, to hook the wire from the upper end of the magnetic ring 109 to the lower end of the magnetic ring 109. During this process, the wire pressing clip 302 of the wire feeding device 300 continuously feeds the wire while maintaining a certain tension on the wire.

[0093] Refer to Figure 14 As shown, the crochet hook 503 rotates 90° to change the arrangement direction of the wires on both sides of the crochet hook 503, so that the wire on one side of the crochet hook 503 approaches the wire hook 704 and enters the wire hooking range of the wire hook 704.

[0094] Stored wire:

[0095] Refer to Figure 15 As shown, the inner support ring 702 rotates, and the wire hook 704 hooks the wire within its wire hooking range. Subsequently, the crochet hook 503 moves upward a certain distance away from the wire and rotates 90° in the reverse direction to completely separate the crochet hook 503 from the wire.

[0096] The inner support ring 702 continues to rotate. The wire feeding device 300 continuously feeds the wire while maintaining a certain tension on the wire until the wire of the required length is wound around the inner support ring 702. In this embodiment, the required length is the wire of L1 / 2 length.

[0097] Refer to Figure 16 As shown, the wire pressing clip 302 of the wire feeding device 300 clamps the wire, and the wire end clip 304 loosens the wire end. The inner support ring 702 continues to rotate until the end with the wire end is completely wound around the outer circumference of the inner support ring 702.

[0098] The first winding mechanism winds the first coil a:

[0099] The wire winding device 400 of the first wire winding mechanism drives the wire clamping jaw 407 to move upward along a semi-circular or approximately semi-circular arc-shaped wire winding trajectory, winds the wire above the magnetic ring 109 and crosses the inner hole of the magnetic ring 109 to complete one wire winding operation. Then, the wire guiding disc 408 rotates to turn the wire guiding hole through which the wire has passed away from directly below the magnetic ring 109, and makes another idle wire guiding hole rotate to directly below the magnetic ring 109, so that when the crochet hook 503 hooks the wire next time, it can pass through a new wire guiding hole. During the next wire storage process, the free end of the wire will go upward from the previous wire guiding hole, break away from the inner support ring 702, and at the same time be pulled down from the wire guiding hole that is currently directly below the magnetic ring 109 to be re-wound onto the inner support ring 702. The two operations are carried out from different wire guiding holes respectively, which can ensure that the upward wire and the downward wire pass through different wire guiding holes to avoid winding and knotting. Refer to Figures 18 to 20 as shown;

[0100] Among them, during the wire winding process, every time a wire is wound on the magnetic ring 109, the wire arranging device 600 drives the magnetic ring 109 to rotate by an angle, so as to realize the uniform arrangement of the wire 109 on the magnetic ring as required, ensure the quality of the magnetic ring induction coil, and improve the wire winding efficiency.

[0101] According to the number of turns required to be wound on the magnetic ring 109, repeat the actions of the wire winding device 400, the crochet hook device 500, the wire arranging device 600 and the wire storage device 700 to wind the front section coil a1 of the first coil a on the magnetic ring 109 and form a wire head. The rotary cylinder 607 drives the magnetic ring 109 to flip 180°, and makes the wire held by the wire head clamp 304 be horizontally placed above the inner hole of the magnetic ring 109. The second wire head clamping jaw 613 moves downward to clamp the wire head formed by the front section coil a1. The crochet hook 503 moves upward through the inner hole of the magnetic ring 109 to hook the wire to below the magnetic ring 109. The wire hook 704 hooks the wire, and the inner support ring 702 rotates to wind the wire onto the inner support ring 702. When the wire feeding device 300 sends out the wire of length L1 / 2 again, the wire cutting device 1000 cuts off the wire to form a new free end. The inner support ring 702 continues to rotate to make the new free end of the wire pass through the inner hole of the magnetic ring 109 and finally wind onto the inner support ring 702. The wire winding device 400 continues to wind the remaining rear section coil a2 of length L1 / 2 until the winding of the first coil a is completed.

[0102] Transfer the magnetic ring 109:

[0103] The intermediate transfer device 800 transfers the magnetic ring 109 with the first coil a wound thereon from the first winding mechanism to the second winding mechanism. Specifically, the transfer cylinder 802 drives the transfer gripper 801 to move towards the magnetic ring 109 and grip the magnetic ring 109. The turntable 803 drives the transfer cylinder 802 and the transfer gripper 801 to rotate to the position of the second winding mechanism, and drives the magnetic ring 109 to rotate in the reverse direction by a certain angle to move it towards the magnetic ring gripper two 609 of the second winding mechanism, so that the magnetic ring gripper two 609 can grip the magnetic ring 109. The structure is compact and the operation is convenient, ensuring that the magnetic ring gripper two 609 can normally grip the magnetic ring 109.

[0104] The second winding mechanism winds the second coil b:

[0105] The lead wire grippers one 610 on both sides of the magnetic ring gripper two 609 of the second winding mechanism grip the two lead wires of the first coil a. The upper wire feeding device 300 at the second winding mechanism feeds out a wire of length L2 / 2. The second winding mechanism winds the front section coil b1 of the second coil b according to the method of the first winding mechanism. Then the rotating cylinder 607 drives the magnetic ring 109 to flip 180°. The wire is horizontally placed above the inner hole of the magnetic ring 109. The lead wire gripper two 613 at the second winding mechanism grips the lead wire left by the front section coil b1, and then winds the rear section coil b2 of the second coil b again according to the winding method of the first winding mechanism. When the winding is completed, the blanking device 900 removes the magnetic ring 109 with the winding completed, and finally completes the overall winding of the magnetic ring 109.

[0106] The present invention feeds the wire to the lead wire gripper 304 through the wire pressing clamp 302 and the wire conduit 303, and hooks the wire through the crochet hook 503. The wire pressing clamp 302 and the wire conduit 303 can reciprocate under the drive of the fourth cylinder 301, without occupying the space above the magnetic ring 109, ensuring that the winding device 400 and the wire arranging device 600 have sufficient working space and reducing the design difficulty; by winding the wire with a lead wire on the inner support ring 702 and setting the rotation angle of the inner support ring 702 according to the wire length, precise control of the wire length is realized, ensuring that the wound coil meets the design requirements; since the lead wire is wound on the inner support ring 702 and an outer baffle 703 can be arranged outside the inner support ring 702, it can ensure that the wire is always stored in the wire accommodating space between the inner support ring 702 and the outer baffle 703, the position of the wire tail is controllable, and the wire is prevented from being wound into other devices, solving the problems of the wire being knotted, broken or the insulating layer being damaged.

[0107] Meanwhile, the outer peripheral length of the inner support ring 702 is 3.14 times its diameter. Winding the wire around the inner support ring 702 can greatly reduce the size of the wire storage mechanism. The wire hook 704 on the inner support ring 702 has a large smooth opening bending radius, which can greatly reduce the bending degree of the wire during winding, avoid large-angle bending of the wire, ensure that the outer insulating layer of the wire is not damaged, and also ensure the flatness of the wire and avoid wire deformation.

[0108] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
