Description

Technical Field

[0001] The present invention relates to an inductor manufacturing device, and in particular to an inductor winding device and a winding method. Background Art

[0002] An inductor includes a frame and a winding coil wound on its surface. The traditional method of winding is manual winding. With the development of technology, some automatic winding equipment has appeared on the market. During production, the frame is clamped by the machine, and the wire-releasing mechanism releases the wire on the outside of the frame and winds it. However, the current machines can only perform winding production on larger inductors. It is difficult to perform operations such as grabbing and positioning on smaller inductors, and automatic winding production cannot be achieved. Therefore, there is an urgent need for a device that can automatically wind inductors, especially for micro inductors. Summary of the invention

[0003] The object of the present invention is to provide an inductor winding device and a winding method to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] The inductor winding device comprises: a workpiece positioning mechanism, comprising a turntable and a clamping unit, the turntable can rotate along an axis in the up-down direction, the clamping unit comprises a cable nozzle seat and an opening and closing clamp, the cable nozzle seat is rotatably connected to one side of the turntable, the cable nozzle seat can rotate along an axis in the horizontal direction, the opening and closing clamp is arranged on the cable nozzle seat, the opening and closing clamp has a clamping space that can be opened and closed, and the cable nozzle seat is connected to a winding rod; a wire-releasing mechanism, located beside the turntable, the wire-releasing mechanism has a turntable that can approach or move away from the cable nozzle seat, the turntable can rotate along an axis in the horizontal direction, a push rod is connected to the turntable at a position of the rotation axis, and a lead reel is connected to a position of the turntable outside the rotation axis; a wire clamping mechanism, located beside the turntable, the wire clamping mechanism has a wire clamping claw that can move along a three-dimensional direction, and the wire clamping claw has a wire clamping space that can be opened and closed; a spot welding mechanism, which has a spot welding head that can approach or move away from the cable nozzle seat.

[0006] The technical solution has at least the following beneficial effects: before the inductor winding process, the inductor wire is released from the wire-releasing mechanism, the inductor wire is released through the lead-in barrel, the wire clamping claw is opened, one end of the inductor wire is extended into the wire clamping space, and then the wire clamping claw is closed to clamp one end of the inductor wire, the clamping space in the opening and closing clamp is opened, the workpiece to be wound is loaded into the clamping space, and then the opening and closing clamp is closed to clamp the workpiece in the clamping space. When the winding process is required, the turntable is rotated to drive the workpiece to the side close to the wire-releasing mechanism, and the wire is released. The rotating frame in the mechanism approaches the direction of the cable nozzle seat, so that the push rod presses against the side of the workpiece away from the cable nozzle seat, and the wire clamping claw also moves close to the workpiece, so that the inductance wire led out of the lead barrel presses against the outside of the workpiece, and then the rotating frame is rotated. Since the push rod is located on the rotating axis of the rotating frame, the push rod can always keep pressing against the workpiece, and the lead barrel is located outside the rotating axis of the rotating frame. With the rotation of the rotating frame, the inductance wire led out of the lead barrel can be wound around the outside of the workpiece. When the inductance wire is wound, the wire clamping claw and the workpiece are relatively moved to The wire is passed around the winding rod, so that the inductance wire connected between the workpiece and the wire clamping claw is against a welding point of the workpiece. At this time, the spot welding head in the spot welding mechanism is close to the workpiece, and the inductance wire is welded to a welding point of the workpiece. The wire clamping claw is away from the workpiece, and the originally clamped inductance wire is pulled, and the inductance wire is broken at the welding point. Then the lead barrel and the workpiece are relatively moved, and the inductance wire is passed around the winding rod, so that the inductance wire connected between the workpiece and the lead barrel is against another welding point of the workpiece, and the wire clamping claw moves close to the lead barrel and the workpiece. The inductor wire is re-clamped by opening and closing the wire clamping space, and the spot welding head welds the inductor wire to another welding point of the workpiece. At this time, the wire clamping claw is away from the workpiece, and the inductor wire connected to the workpiece can be pulled off from the welding point to complete the winding. In this way, the workpiece can be positioned from multiple directions by opening and closing the clamp and the ejector rod, which improves the stability of workpiece positioning. It is especially suitable for winding smaller inductors, and the winding rod is used to cleverly guide the wound inductor wire to the welding point position, thereby realizing automatic and efficient winding production of the inductor.

[0007] As a further improvement of the above technical solution, the opening and closing clamp includes a fixed block connected to the cable nozzle seat, a movable block rotatably connected to the cable nozzle seat, and a first spring connected between the fixed block and the movable block, the fixed block and the movable block form the clamping space on the side away from the turntable, the movable block can be rotated on the cable nozzle seat until the clamping space is opened or closed, the first spring has a tendency to press the movable block to rotate until the clamping space is closed, and a first rotation drive and a telescopic drive are arranged in the turntable, the first rotation drive is transmission-connected to the cable nozzle seat, the clamping unit also includes a top block, the telescopic drive is transmission-connected to the top block, the telescopic drive can drive the top block to press against the movable block and make the first spring elastically compressed. When the workpiece needs to be loaded, the telescopic drive in the turntable works and drives the top block to move, so that the top block is pressed against the movable block, driving the movable block to rotate, and the end of the movable block close to the turntable rotates toward the fixed block, elastically compressing the first spring, and the end of the movable block away from the turntable rotates away from the fixed block, opening the clamping space between the fixed block and the movable block. At this time, the workpiece can be loaded into the clamping space, and then the telescopic drive drives the movable block to return and reset, and the movable block rotates and resets under the elastic force of the first spring, so that the clamping space is closed, thereby utilizing the movable block and the fixed block to clamp and position the workpiece, and when it is necessary to drive the workpiece to rotate, the first rotating drive member provides a rotational driving force to the cable nozzle seat.

[0008] As a further improvement of the above technical solution, clamping groups are respectively arranged on both sides of the turntable, and the two clamping groups respectively include a plurality of clamping units arranged on one side of the turntable, and the number of the first rotary drive and the telescopic drive are two respectively, one of the first rotary drive is connected to the plurality of cable nozzle seats in one clamping group, and one of the telescopic drive is connected to the plurality of top blocks in one clamping group. The clamping groups on both sides of the turntable can form two stations for loading and clamping workpieces respectively. During operation, the station on one side of the turntable can load the workpieces, and put the plurality of workpieces into the clamping spaces of the plurality of clamping units respectively, while the station on the other side of the turntable can perform winding production. When the winding is completed, the turntable rotates, and the stations on both sides are interchanged, which can save time for loading and unloading the workpieces and improve production efficiency.

[0009] As a further improvement of the above technical solution, a connecting rod is connected to the rotation axis position of the rotating frame away from the rotating table, a threading channel is arranged in the connecting rod, the push rod is slidably connected to the side of the rotating frame close to the rotating table, a limit shoulder is formed on the outer side of the end of the push rod close to the rotating table, and a second spring is sleeved on the outer side of the push rod, and the two ends of the second spring are respectively against the rotating frame and the limit shoulder, and the second spring has a tendency to press the limit shoulder toward the rotating table. The inductor wire to be wound passes through the threading channel of the connecting rod and then passes through the lead bobbin. When the workpiece needs to be wound, the rotating frame approaches the cable nozzle seat and presses the push rod against one side of the workpiece. As the rotating frame gradually approaches, the push rod gradually slides into the rotating frame and elastically compresses the second spring. At this time, the push rod uses the elastic force of the second spring to elastically press against the workpiece, which can not only improve the positioning effect of the workpiece, but also prevent the workpiece from being damaged by excessive pressure. When the winding production is completed, the rotating frame is away from the cable nozzle seat. At this time, the elastic force of the second spring restores the push rod to reset from the rotating frame.

[0010] As a further improvement of the above technical solution, the wire-paying mechanism includes a base plate, a wire-paying left and right translation drive, a first sliding seat, a wire-paying front and back translation drive, and a second sliding seat. The wire-paying left and right translation drive is arranged on the base plate, the wire-paying left and right translation drive is transmission-connected to the first sliding seat, the wire-paying left and right translation drive can drive the first sliding seat to move left and right, the wire-paying front and back translation drive is arranged on the first sliding seat, the wire-paying front and back translation drive is transmission-connected to the second sliding seat, the wire-paying front and back translation drive can drive the second sliding seat to move front and back, the turntable is rotationally connected to the second sliding seat, the second sliding seat is connected to a second rotation drive, and the second rotation drive is transmission-connected to the turntable. The turret can move in the left and right and front and back directions through the left and right translation drive and the front and back translation drive for wire pay-off, so as to move closer to or farther away from the cable nozzle seat. During wire winding production, the cable nozzle seat adjusts its position in the front and back directions so that the push rod is opposite to the workpiece, and then moves in the left and right directions so that the push rod is pressed against the workpiece, and then the turret is driven to rotate by the second rotation drive to realize winding of the workpiece.

[0011] As a further improvement of the above technical solution, the wire clamping mechanism includes a wire clamping left and right translation drive, a wire clamping front and back translation drive, a wire clamping translation seat, and a wire clamping lifting drive. The wire clamping left and right translation drive is transmitted and connected to the base plate, and the wire clamping left and right translation drive drives the base plate to move left and right. The wire clamping front and back translation drive is arranged on the base plate, and the wire clamping front and back translation drive is transmitted and connected to the wire clamping translation seat, and the wire clamping front and back translation drive drives the wire clamping translation seat to move forward and backward. The wire clamping lifting drive is arranged on the wire clamping translation seat, and the wire clamping lifting drive is transmitted and connected to the wire clamping claw, and the wire clamping lifting drive drives the wire clamping claw to move up and down. The wire clamping claw can move in three directions, left and right, front and back, and up and down, respectively, driven by the wire clamping left and right translation drive, the wire clamping front and back translation drive, and the wire clamping lifting drive. When the wire clamping left and right translation drive drives the bottom plate to move left and right to drive the wire clamping claw to move left and right, the turntable is also driven to move in the left and right direction at the same time. At this time, the left and right movement of the turntable can be powered by the wire-releasing left and right translation drive and the wire clamping left and right translation drive. When in use, by adjusting the power provided by different drives, the effect of first quickly moving the turntable into position and then slowly and accurately adjusting the stroke can be achieved.

[0012] As a further improvement of the above technical solution, the present invention also includes a shaping mechanism, which has a hot air blowing pipe that can be close to or away from the cable nozzle seat. After the winding is completed, the hot air blowing pipe approaches the cable nozzle seat and blows hot air to the workpiece after the winding is completed, so that the wound inductor wire can be shaped, effectively preventing the inductor wire from being easily loosened. After the workpiece is shaped by blowing hot air, the hot air blowing pipe is reset away from the cable nozzle seat.

[0013] As a further improvement of the above technical solution, the shaping mechanism includes a fixed frame, a shaping front and rear translation drive, a shaping translation seat, a shaping lifting drive, a shaping lifting seat and a hot blow pipe, the shaping front and rear translation drive is arranged on the fixed frame, the shaping front and rear translation drive is transmission-connected to the shaping translation seat, the shaping front and rear translation drive can drive the shaping translation seat to move forward and backward, the shaping lifting drive is arranged on the shaping translation seat, the shaping lifting drive is transmission-connected to the shaping lifting seat, the shaping lifting drive can drive the shaping lifting seat to move up and down, and the hot blow pipe is connected to the shaping lifting seat. The shaping front and rear translation drive and the shaping lifting drive can respectively provide driving force for the hot blow pipe to move along the front and rear and up and down directions, so that the hot blow pipe can be moved close to or away from the cable nozzle seat. For example, when the hot blow pipe needs to be close to the cable nozzle seat, the shaping front and rear translation drive first drives the hot blow pipe to be translated to above the workpiece, and then the shaping lifting drive drives the hot blow pipe to move down close to the workpiece, so that the hot air can be blown directly to the winding position. After completion, the shaping lifting drive drives the hot blow pipe to move up away from the workpiece, and then the shaping front and rear translation drive drives the hot blow pipe to be translated away from the workpiece.

[0014] As a further improvement of the above technical solution, the spot welding mechanism includes a spot welding front and back translation drive, a spot welding translation seat, a spot welding lifting drive and a spot welding lifting seat. The spot welding front and back translation drive is arranged on the fixed frame, and the spot welding front and back translation drive is transmission-connected to the spot welding translation seat. The spot welding front and back translation drive can drive the spot welding translation seat to move forward and backward. The spot welding lifting drive is arranged on the spot welding translation seat, and the spot welding lifting drive is transmission-connected to the spot welding lifting seat. The spot welding lifting drive can drive the spot welding lifting seat to move up and down, and the spot welding head is connected to the spot welding lifting seat. The spot welding forward and backward translation drive and the spot welding lifting drive can respectively provide driving force for the spot welding head to move along the forward and backward and up and down directions, so that the spot welding head can be moved close to or away from the cable nozzle seat. For example, when the spot welding head needs to be close to the cable nozzle seat, the spot welding forward and backward translation drive first drives the spot welding head to move horizontally above the workpiece, and then the spot welding lifting drive drives the spot welding head to move down close to the workpiece to spot weld the welding point position of the workpiece. After completion, the spot welding lifting drive drives the spot welding head up and away from the workpiece, and then the spot welding forward and backward translation drive drives the spot welding head to move horizontally away from the workpiece.

[0039] Reference Figure 1 and Figure 2 The inductor winding device includes a workpiece positioning mechanism 100, a wire release mechanism 200, a wire clamping mechanism 300 and a spot welding mechanism 400, wherein the workpiece positioning mechanism 100 includes a turntable 110 and a clamping unit 120, the turntable 110 can be driven by a rotary cylinder or a driving motor to realize the rotation of the axis along the up and down directions, the clamping unit 120 includes a cable mouth seat 121 and an opening and closing clamp, the cable mouth seat 121 is rotatably connected to one side of the turntable 110, the cable mouth seat 121 can rotate along the axis in the horizontal direction, the opening and closing clamp is arranged on the cable mouth seat 121, the opening and closing clamp has an openable clamping space 126, and the cable mouth seat 121 is connected to a winding rod 122; the wire release mechanism 200 is located on the side of the turntable 110, the wire release mechanism 200 is located on the side of the turntable 110, and the wire release mechanism 200 is located on the side of the turntable 110. The wire mechanism 200 has a rotating frame 210 that can approach or move away from the cable nozzle seat 121, and the rotating frame 210 can rotate along the horizontal axis. A push rod 211 is connected to the rotating frame 210 at the position of the rotation axis, and a lead reel 212 is connected to the rotating frame 210 at a position outside the rotation axis; the wire clamping mechanism 300 is located on the side of the turntable 110, and the wire clamping mechanism 300 has a wire clamping claw 310 that can move along the three-dimensional direction, and the wire clamping claw 310 has an openable and closable wire clamping space. The wire clamping claw 310 can use an electric clamping finger or a pneumatic clamping finger as a driving source to drive the two clamping blocks to approach or move away from each other, thereby forming an open and closed wire clamping space; the spot welding mechanism 400 has a spot welding head 410 that can approach or move away from the cable nozzle seat 121.

[0040] As can be seen from the above, before the inductor winding process, the inductor wire is released from the wire-releasing mechanism 200, the inductor wire is released through the lead barrel 212, the wire clamping claw 310 is opened, one end of the inductor wire is extended into the wire clamping space, and then the wire clamping claw 310 is closed to clamp one end of the inductor wire, the clamping space 126 in the opening and closing clamp is opened, the workpiece to be wound is loaded into the clamping space 126, and then the opening and closing clamp is closed to clamp the workpiece in the clamping space 126. When the winding process is required, the turntable 110 rotates to drive the workpiece to the side close to the wire-releasing mechanism 200, and the turntable 2 in the wire-releasing mechanism 200 is opened. 10 is moved toward the direction of the cable nozzle seat 121, so that the push rod 211 is pressed against the side of the workpiece away from the cable nozzle seat 121, and the wire clamping claw 310 is also moved toward the workpiece, so that the inductance wire drawn from the wire guide barrel 212 is pressed against the outside of the workpiece, and then the rotating frame 210 is rotated. Since the push rod 211 is located on the rotation axis of the rotating frame 210, the push rod 211 can always keep pressing against the workpiece, and the wire guide barrel 212 is located outside the rotation axis of the rotating frame 210. As the rotating frame 210 rotates, the inductance wire drawn from the wire guide barrel 212 can be wound around the outside of the workpiece. When the inductance wire is wound, the relatively moving wire clamping claw 310 is moved. The claw 310 and the workpiece are moved to pass the inductor wire around the winding rod 122, so that the inductor wire connected between the workpiece and the wire clamping claw 310 is against a welding point of the workpiece. At this time, the spot welding head 410 in the spot welding mechanism 400 is close to the workpiece, and the inductor wire is welded to a welding point of the workpiece. The wire clamping claw 310 is away from the workpiece, and the originally clamped inductor wire is pulled, and the inductor wire is broken at the welding point. Then, the lead cylinder 212 and the workpiece are relatively moved to pass the inductor wire around the winding rod 122, so that the inductor wire connected between the workpiece and the lead cylinder 212 is against another welding point of the workpiece, and the wire clamping claw 310 is moved. The inductor wire is approached between the lead barrel 212 and the workpiece, and the inductor wire is re-clamped by opening and closing the wire clamping space. The spot welding head 410 welds the inductor wire to another welding point of the workpiece. At this time, the wire clamping claw 310 is far away from the workpiece, and the inductor wire connected to the workpiece can be pulled off from the welding point to complete the winding. In this way, the workpiece is positioned from multiple directions by opening and closing the clamp and the push rod 211, which improves the stability of the workpiece positioning. It is particularly suitable for winding smaller inductors, and the winding rod 122 is used to cleverly guide the wound inductor wire to the welding point position, thereby realizing automatic and efficient winding production of the inductor.

[0041] The opening and closing clamp is mainly used to clamp and position the workpiece. During the entire winding production process, the opening and closing clamp maintains the workpiece clamped for most of the time. Therefore, in order to better maintain the clamping of the workpiece by the opening and closing clamp, in this embodiment, Figure 3As shown, the opening and closing clamp includes a fixed block 123 connected to the cable nozzle seat 121, a movable block 124 rotatably connected to the cable nozzle seat 121, and a first spring 125 connected between the fixed block 123 and the movable block 124. The fixed block 123 and the movable block 124 form the clamping space 126 on the side away from the turntable 110. The movable block 124 can be rotated on the cable nozzle seat 121 until the clamping space 126 is opened or closed. The first spring 125 has a tendency to press the movable block 124 to rotate until the clamping space 126 is closed. The turntable 110 is provided with a first rotation drive 111 and a telescopic drive. The first rotation drive 111 is transmission-connected to the cable nozzle seat 121. The clamping unit 120 also includes a top block 127. The telescopic drive is transmission-connected to the top block 127. The telescopic drive can drive the top block 127 to press against the movable block 124 and cause the first spring 125 to be elastically compressed.

[0042] In the opening and closing clamp of the above-mentioned embodiment, in the natural state, the movable block 124 can maintain its position state under the elastic force of the first spring 125, so that the clamping space 126 formed by the movable block 124 and the fixed block 123 on the side away from the turntable 110 remains closed. When it is necessary to load a workpiece, the telescopic drive in the turntable 110 works and drives the top block 127 to move, so that the top block 127 presses against the movable block 124, driving the movable block 124 to rotate, and the end of the movable block 124 close to the turntable 110 rotates toward the fixed block 123, elastically compressing the first spring 125. , and the end of the movable block 124 away from the turntable 110 rotates away from the fixed block 123, opening the clamping space 126 between the fixed block 123 and the movable block 124. At this time, the workpiece can be loaded into the clamping space 126, and then the telescopic drive drives the movable block 124 to return and reset. The movable block 124 rotates and resets under the elastic force of the first spring 125, so that the clamping space 126 is closed, so that the movable block 124 and the fixed block 123 are used to clamp and position the workpiece. When it is necessary to drive the workpiece to rotate, the first rotary drive 111 provides a rotary driving force to the cable nozzle seat 121. In actual application, a protrusion is formed on the side of the movable block 124 away from the fixed block 123, so as to facilitate the abutment with the top block 127, and a roller is provided on the side of the top block 127 close to the movable block 124. When the top block 127 approaches the movable block 124, the roller and the protrusion abut, which can reduce the friction between the two and improve the smoothness of the opening and closing of the clamping space 126.

[0043] Before loading, the turntable 110 rotates the clamping unit 120 to the side away from the rotating frame 210 to facilitate loading. After completion, the turntable 110 rotates to rotate the clamping unit 120 clamped with the workpiece to face the turntable 210. In order to reduce the waiting time when loading the workpiece, in the present embodiment, clamping groups are respectively arranged on both sides of the turntable 110, and the two clamping groups respectively include a plurality of clamping units 120 arranged on one side of the turntable 110. The number of the first rotary drive 111 and the number of the telescopic drive are two respectively. One of the first rotary drive 111 is transmission-connected to the plurality of cable nozzle seats 121 in one of the clamping groups. For example, the first rotary drive 111 can be driven by a belt to simultaneously drive the plurality of cable nozzle seats 121 in the same clamping group to rotate. One of the telescopic drive is transmission-connected to the plurality of top blocks 127 in one of the clamping groups. For example, the plurality of top blocks 127 are connected to the same transmission plate. The movable end of the telescopic drive is connected to the transmission plate, and the plurality of top blocks 127 are driven to move through the transmission plate. The clamping groups on both sides of the turntable 110 can form two workstations for loading and clamping workpieces. During operation, the workstation on one side of the turntable 110 can load the workpieces, and put multiple workpieces into the clamping spaces 126 of multiple clamping units 120, while the workstation on the other side of the turntable 110 can perform winding production. When the winding is completed, the turntable 110 rotates and the workstations on both sides are interchanged, which can save time for loading and unloading workpieces and improve production efficiency. In actual applications, the number of clamping units 120 in each clamping group is equal to the number of rotating frames 210, the number of clamping claws 310 and the number of spot welding heads 410, so as to achieve simultaneous winding production of multiple workpieces.

[0044] When the push rod 211 is pressed against one side of the workpiece, the push rod 211 may be directly driven by the driving member to rigidly contact the workpiece. In this case, the push rod 211 may easily exert too much pressure on the workpiece. Therefore, in order to prevent the workpiece from being pressed too much, in this embodiment, Figure 5As shown, a connecting rod 213 is connected to the rotation axis position of the rotating frame 210 away from the turntable 110, and a threading channel is provided in the connecting rod 213. The push rod 211 is slidably connected to the side of the rotating frame 210 close to the turntable 110. A limiting shoulder 214 is formed on the outer side of the end of the push rod 211 close to the turntable 110. A second spring 215 is sleeved on the outer side of the push rod 211, and the two ends of the second spring 215 respectively abut against the rotating frame 210 and the limiting shoulder 214. The second spring 215 has a tendency to press the limiting shoulder 214 toward the turntable 110. The inductor wire that needs to be wound passes through the threading channel of the connecting rod 213 and then passes through the lead barrel 212. When the workpiece needs to be wound, the rotating frame 210 approaches the cable nozzle seat 121 and presses the push rod 211 against one side of the workpiece. As the rotating frame 210 gradually approaches, the push rod 211 gradually slides into the rotating frame 210 and elastically compresses the second spring 215. At this time, the push rod 211 uses the elastic force of the second spring 215 to elastically press against the workpiece, which can not only improve the positioning effect of the workpiece, but also prevent the workpiece from being damaged by excessive pressure. When the winding production is completed, the rotating frame 210 is away from the cable nozzle seat 121. At this time, the elastic force of the second spring 215 restores the push rod 211 from the rotating frame 210 and resets it.

[0045] The wire release mechanism 200 includes a wire release device 260 and a tensioner. The wire release device 260 releases the inductor wire to the tensioner, and the tensioner is used to provide tension to the inductor wire, and then the inductor wire is released to the workpiece for winding. Specifically, Figure 4 As shown, the wire-paying mechanism 200 includes a base plate 220, a wire-paying left and right translation drive 230, a first sliding seat 240, a wire-paying front and back translation drive, and a second sliding seat 250.

The rotating frame 210 can realize movement in the left and right and front and back directions through the left and right translation drive 230 and the front and back translation drive for wire laying, so as to approach or move away from the rope nozzle seat 121. During the winding production, the rope nozzle seat 121 adjusts its position in the front and back directions so that the push rod 211 is opposite to the workpiece, and then moves in the left and right directions so that the push rod 211 is pressed against the workpiece, and then the second rotation drive drives the rotating frame 210 to rotate to realize the winding of the workpiece.

[0046] The wire clamping mechanism 300 mainly has a driving source that can move in a three-dimensional direction to drive the wire clamping claw 310 to move in a three-dimensional direction. Specifically, the wire clamping mechanism 300 includes a left and right translation drive for the wire clamping, a front and back translation drive for the wire clamping, a translation seat 330 for the wire clamping, and a lifting drive 340 for the wire clamping. The left and right translation drive for the wire clamping drives the bottom plate 220 to move left and right. The front and back translation drive 320 for the wire clamping is arranged on the bottom plate 220. The front and back translation drive 320 for the wire clamping drives the translation seat 330. The front and back translation drive 320 for the wire clamping drives the translation seat 330 to move forward and backward. The lifting drive 340 for the wire clamping is arranged on the translation seat 330. The lifting drive 340 for the wire clamping is transmission-connected to the wire clamping claw 310. The lifting drive 340 for the wire clamping drives the wire clamping claw 310 to move up and down. The wire clamping claw 310 can move in three-dimensional directions of left and right, front and back, and up and down respectively under the drive of the wire clamping left and right translation drive, the wire clamping front and back translation drive 320, and the wire clamping lifting drive 340. When the wire clamping left and right translation drive drives the base plate 220 to move left and right to drive the wire clamping claw 310 to move left and right, the rotating frame 210 is also driven to move in the left and right direction at the same time. At this time, the left and right movement of the rotating frame 210 can be powered by the wire-releasing left and right translation drive 230 and the wire clamping left and right translation drive. When in use, by adjusting the power provided by different drives, the effect of first quickly moving the rotating frame 210 into place and then slowly and accurately adjusting the stroke can be achieved.

[0047] The present invention also includes a shaping mechanism 500, such as Figure 6 As shown, the shaping mechanism 500 has a hot air blowing pipe 550 that can be close to or away from the cable nozzle seat 121. After the winding is completed, the hot air blowing pipe 550 approaches the cable nozzle seat 121 and blows hot air to the workpiece after the winding is completed, so that the wound inductor wire can be shaped and the inductor wire can be effectively prevented from being easily loosened. After the workpiece is shaped by blowing hot air, the hot air blowing pipe 550 is moved away from the cable nozzle seat 121 and reset.

[0048] The positioning mechanism has a driving source that can drive the hot blow pipe 550 to approach or move away from the workpiece. In this embodiment, the shaping mechanism 500 includes a fixed frame 510, a shaping front and rear translation drive, a shaping translation seat 520, a shaping lifting drive 530, a shaping lifting seat 540 and a hot blow pipe 550. The shaping front and rear translation drive is arranged on the fixed frame 510, and the shaping front and rear translation drive is transmission-connected to the shaping translation seat 520. The shaping front and rear translation drive can drive the shaping translation seat 520 to move forward and backward. The shaping lifting drive 530 is arranged on the shaping translation seat 520, and the shaping lifting drive 530 is transmission-connected to the shaping lifting seat 540. The shaping lifting drive 530 can drive the shaping lifting seat 540 to move up and down, and the hot blow pipe 550 is connected to the shaping lifting seat 540. The shaping front and rear translation drive and shaping lifting drive 530 can respectively provide driving force for the hot blow pipe 550 to move in the front and rear and up and down directions, so that the hot blow pipe 550 can be close to or away from the cable nozzle seat 121. For example, when the hot blow pipe 550 needs to be close to the cable nozzle seat 121, the shaping front and rear translation drive first drives the hot blow pipe 550 to translate above the workpiece, and then the shaping lifting drive 530 drives the hot blow pipe 550 to move down close to the workpiece, so that the hot air can be blown directly to the winding position. After completion, the shaping lifting drive 530 drives the hot blow pipe 550 to move up away from the workpiece, and then the shaping front and rear translation drive drives the hot blow pipe 550 to translate away from the workpiece. In actual application, the hot blow pipe 550 is connected to an external blowing device, and the blowing device provides hot air to the hot blow pipe 550.

[0049] After the winding is completed, the inductor wire needs to be spot welded to the workpiece itself, and this spot welding process is completed by the spot welding mechanism 400. The spot welding mechanism 400 has a driving source that can drive the spot welding head 410 to approach or move away from the workpiece. Specifically, the spot welding mechanism 400 includes a spot welding front and back translation drive, a spot welding translation seat 420, a spot welding lifting drive 430 and a spot welding lifting seat 440. The spot welding front and back translation drive is arranged on the fixed frame 510, and the spot welding front and back translation drive is transmission-connected to the spot welding translation seat 420.

The spot welding lifting drive 430 can drive the spot welding lifting seat 440 to move up and down, and the spot welding head 410 is connected to the spot welding lifting seat 440. The spot welding forward and backward translation drive and the spot welding lifting drive 430 can respectively provide driving force for the spot welding head 410 to move along the forward and backward and up and down directions, so that the spot welding head 410 can be moved close to or away from the cable nozzle seat 121. For example, when the spot welding head 410 needs to be close to the cable nozzle seat 121, the spot welding forward and backward translation drive first drives the spot welding head 410 to be translated above the workpiece, and then the spot welding lifting drive 430 drives the spot welding head 410 to move down close to the workpiece to spot weld the welding point position of the workpiece. After completion, the spot welding lifting drive 430 drives the spot welding head 410 to move up away from the workpiece, and then the spot welding forward and backward translation drive drives the spot welding head 410 to be translated away from the workpiece.

[0050] A winding method, using the above-mentioned inductor winding device, includes but is not limited to the following steps:

[0051] Step S100, laying out the inductor wire through the lead barrel 212, and clamping one end of the inductor wire with the opening and closing clamp;

[0052] Step S200, loading the workpiece into the clamping space 126;

[0053] Step S300, the push rod 211 is pressed against a side of the workpiece away from the cable nozzle seat 121, and the rotating frame 210 is relatively rotated so that the inductor wire is wound around the outside of the workpiece;

[0054] Step S400, after the inductor wire is wound, hot air is blown toward the workpiece to shape it;

[0055] Step S500, relatively moving the opening and closing clamp and the workpiece, winding the inductor wire around the winding rod 122, so that the inductor wire abuts against a welding point of the workpiece, and the spot welding head 410 welds the inductor wire to a welding point of the workpiece;

[0056] In step S600, the opening and closing clamp and the lead tube 212 are relatively moved to pass the inductor wire around the winding rod 122 so that the inductor wire abuts against another welding point of the workpiece. The opening and closing clamp clamps the inductor wire between the lead tube 212 and the workpiece, and the spot welding head 410 welds the inductor wire to another welding point of the workpiece.

[0057] The present invention positions the workpiece from multiple directions by means of the opening and closing clamps and the ejector rod 211, thereby improving the stability of the workpiece positioning. The present invention is particularly suitable for winding a smaller inductor, and uses the winding rod 122 to skillfully guide the wound inductor wire to the soldering point position, thereby realizing automatic and efficient winding production of the inductor.

[0058] In order to further improve the overall automation level, such as Figure 7 As shown, a vibration plate 600, a transfer mechanism 700, a loading mechanism 800 and a unloading mechanism 900 may also be provided. The vibration plate 600 is mainly used for discharging the workpieces. The transfer mechanism 700 is mainly used for transferring the output of the vibration plate 600 to the side of the workpiece positioning mechanism 100. The loading mechanism 800 is mainly used for loading the workpiece transferred into place by the transfer mechanism 700 to the opening and closing clamp. The unloading mechanism 900 is mainly used for unloading the workpiece after winding.

[0059] like Figure 8 As shown, the discharge end of the vibration disk 600 is connected to a straight vibration guide groove 610, and the end of the straight vibration guide groove 610 away from the vibration disk 600 is provided with a blocking block 620 that can cover or open the end of the straight vibration guide groove 610. For example, a cylinder or an electric screw can be installed at the end of the straight vibration guide groove 610, and the cylinder or the electric screw provides a driving force for reciprocating motion in a straight direction to the blocking block 620, so that the blocking block 620 covers or opens the end of the straight vibration guide groove 610.

[0060] The transfer mechanism 700 has a discharge plate 710 that can move between the stop block 620 and the workpiece positioning mechanism 100. The discharge plate 710 is provided with a discharge groove on the side opposite to the straight vibration guide groove 610. In actual application, the discharge plate 710 is driven by a cylinder, an electric screw or a hydraulic cylinder to move in the front and rear directions, thereby realizing the movement between the stop block 620 and the workpiece positioning mechanism 100. There can be multiple discharge grooves on the discharge plate 710, so that multiple workpieces can be loaded on the discharge plate 710 at a single time.

[0061] The feeding mechanism 800 has a driving source that can drive the feeding nozzle 816 to move and adjust its direction and position. Specifically, Fig. 9As shown, the feeding mechanism 800 includes a feeding lifting drive, a feeding lifting seat 811, a feeding left and right translation drive 812, a feeding translation seat 813, a feeding rotation drive 814 and a feeding turntable 815. The feeding lifting drive is transmission-connected to the feeding lifting seat 811, and the feeding lifting drive can drive the feeding lifting seat 811 to move up and down. The feeding left and right translation drive 812 is arranged on the feeding lifting seat 811, and the feeding left and right translation drive 812 is transmission-connected to the feeding translation seat 813, and the feeding left and right translation drive 812 can drive the feeding translation seat 813 to move left and right. The feeding rotation drive 814 is rotationally arranged on the feeding translation seat 813, and the feeding rotation drive 814 is transmission-connected to the feeding turntable 815, and the feeding rotation drive 814 can drive the feeding turntable 815 to rotate up and down. The feeding nozzle 816 is connected to the feeding turntable 815. The loading lifting drive and the loading left and right translation drive 812 can provide driving force for the loading suction nozzle 816 to move in the up and down directions and left and right directions respectively, and the loading rotation drive 814 can provide a rotational driving force for the loading suction nozzle 816. When it is necessary to take materials from the discharge plate 710, the loading left and right translation drive 812 can drive the loading suction nozzle 816 to move closer to the discharge plate 710, and the loading lifting drive drives the loading suction nozzle 816 to move down close to the discharge slot. At the same time, the loading rotation drive 81 The loading suction nozzle 816 is driven to rotate so that the loading suction nozzle 816 faces downward. When the loading suction nozzle 816 approaches and presses the workpiece, the workpiece is sucked. Then, the loading lifting drive drives the loading suction nozzle 816 to move upward. The loading rotation drive 814 drives the loading suction nozzle 816 to rotate toward the clamping space 126. The loading left and right translation drive 812 drives the loading suction nozzle 816 to approach the clamping space 126, so as to transfer the workpiece from the discharge slot to the clamping space 126.

[0062] The feeding mechanism 800 also includes an elevated frame 821, a pressure lifting drive and a pressure lifting plate 822. The elevated frame 821 is connected to the top side of the feeding translation seat 813 and extends in the direction of the opening and closing clamp.

The pressure lifting drive can drive the pressure lifting plate 822 to move up and down. A pressure block 823 is connected to the pressure lifting plate 822. The elevated frame 821 raises the installation position of the pressure block 823 so that the pressure block 823 is installed above the loading nozzle 816. When the loading nozzle 816 completes the transfer of the workpiece from the discharge trough to the clamping space 126 by suction, the loading nozzle 816 is driven by the pressure lifting drive to move down and press against the workpiece, further pressing the workpiece down in the discharge trough to position it. Then the pressure lifting drive drives the loading nozzle 816 to move up and reset, in preparation for pressing the workpiece into the clamping space 126 for positioning next time.

[0063] In order to make the pressing block 823 have an elastic buffering effect when pressing the workpiece, in this embodiment, a slider 824 is slidably connected to the press material lifting plate 822 in the up-down direction, the pressing block 823 is connected to the bottom side of the slider 824, and a buffer spring 825 is connected between the slider 824 and the press material lifting plate 822, and the buffer spring 825 has a tendency to pull the slider 824 downward to the bottom of the stroke. When the pressing block 823 moves down to press against the workpiece, the slider 824 moves up relatively on the press material lifting plate 822, stretching the buffer spring 825 in the up-down direction. At this time, the buffer spring 825 plays an elastic buffering effect when pressing against the workpiece, which is helpful to prevent the pressure of the pressing block 823 from being too large to crush the workpiece. After the workpiece is pressed into the clamping space 126, the press material lifting plate 822 moves up, and the elastic restoring force of the buffer spring 825 and the gravity of the slider 824 itself can make the slider 824 move down and reset.

The unloading translation drive 920 can drive the unloading translation seat 930 to move forward and backward. The unloading lifting drive 940 is arranged on the unloading translation seat 930. The lifting drive 940 is transmission-connected to the unloading lifting frame 950, and the unloading lifting drive 940 can drive the unloading lifting frame 950 to move up and down.

The unloading lifting drive 940 and the unloading left and right translation drive can provide driving force for the unloading suction nozzle 990 to move along the up and down and front and back directions respectively, and the unloading rotation drive 960 provides rotational driving force for the unloading suction nozzle 990. After the winding of the workpiece is completed, the unloading left and right translation drive can drive the unloading suction nozzle 990 to move horizontally close to the clamping space 126. The unloading lifting drive 940 drives the unloading suction nozzle 990 to move downward close to the workpiece after the winding is completed. At the same time, the unloading rotation drive 960 drives the unloading suction nozzle 990 to rotate, so that the unloading suction nozzle 990 faces downward. When the unloading suction nozzle 990 approaches and presses the workpiece, the workpiece is sucked, and then the unloading lifting drive 940 drives the unloading suction nozzle 990 to move upward, and moves the workpiece out of the clamping space 126 to complete the material removal of the workpiece, and then the unloading translation drive 920 drives the workpiece away from the clamping space 126 and transfers it to the next workstation.
