Description

Technical Field

[0001] The invention relates to the field of coil processing equipment, and in particular to a winding spindle assembly and a winding device. Background Art

[0002] The winding process in the existing winding device is generally as follows: the rotating spindle fixes the frame, and after the wire passes through the wire nozzle, the wire clamping assembly clamps the wire end. Under the guidance of the wire nozzle, the wire passes around the frame, and the rotating spindle drives the frame to rotate, thereby realizing winding. After the winding is completed, the cutter cuts the wire, the coil is cut, and the winding process is completed. In the existing winding device, the rotating spindle and the wire clamping assembly are two independent components. Due to the component layout of the winding device, the clamping frame end of the rotating spindle is difficult to keep on the same horizontal plane with the clamping end in the wire clamping assembly, resulting in the wire ends and tails extending from the coil being too long, which may affect subsequent welding.

[0003] The rotating spindle in the existing winding device has different structures according to the different shapes of the frame, so as to more firmly fix the frame to be wound. The rotating spindle in the existing winding device can fix the frame by penetration or cable nozzle. Regardless of which method is adopted, most of the existing rotating spindles extend in the horizontal direction, while the wire extends in the vertical direction; when the frame is in an I-shaped shape, it is difficult to fix the frame by rotating along the horizontal extension; or the frame is turned to facilitate the rotating spindle to fix the frame, but the complexity of the winding device is increased to a certain extent. Summary of the invention

[0004] A first object of the present invention is to provide a winding spindle assembly with a wire clamping function.

[0005] A second object of the present invention is to provide a wire winding device comprising the wire winding spindle assembly described above.

[0006] In order to achieve the above-mentioned first purpose, the winding spindle assembly provided by the present invention includes a rotating spindle assembly and a wire clamping assembly, the rotating spindle assembly includes a spindle and a movable driving assembly, the movable driving assembly drives the spindle to move; the wire clamping assembly is arranged on the radial outer wall of the spindle, the wire clamping assembly includes a first clamping block, a second clamping block and a clamping block driving assembly, the first clamping block is fixedly arranged on the radial outer wall of the spindle, the clamping block driving assembly drives the first clamping block to move toward or away from the second clamping block, and the first clamping block moves along the circumferential direction of the spindle.

[0007] It can be seen from the above scheme that the main shaft is used to fix the skeleton, and can be fixed by penetration or cable nozzles; the mobile drive assembly drives the main shaft to rotate, and the rotation of the main shaft drives the rotation of the skeleton, which is convenient for winding the skeleton; the wire clamping assembly is arranged on the outer wall, and the rotating main shaft assembly and the wire clamping assembly are integrated into one, thereby reducing the setting of components in the winding device, and making the layout of the winding device components have a wider operating space to adapt to the winding process of skeletons of more different shapes; the operator can set the position of the wire clamping assembly on the outer wall of the main shaft according to the required length of the wire head. When the first clamping block and the second clamping block are respectively located in the same plane as the skeleton fixed end of the main shaft, while ensuring that the skeleton fixed end of the main shaft firmly fixes the skeleton, the distance between the wire clamping assembly and the skeleton fixed end of the main shaft is the shortest, so that the length of the wire head is short, which better guarantees the subsequent welding effect of the coil.

[0008] A further solution is that the clamping block driving assembly includes a tension spring, a first movable ring and a movable ring driving assembly. The first movable ring is sleeved outside the main shaft. The first movable ring is fixedly connected to the first clamping block. The movable ring driving assembly drives the first movable ring to move circumferentially along the main shaft. The tension spring is respectively connected to the first movable ring and the main shaft.

[0009] It can be seen that the moving ring driving assembly drives the first moving ring to move, and since the first moving ring is fixedly connected to the first clamping block, the movement of the first moving ring drives the movement of the first clamping block, so that the first clamping block moves away from the second clamping block, and the wire enters between the first clamping block and the second clamping block; since the tension spring is respectively connected to the first moving ring and the first clamping block, the movement of the first moving ring drives the tension spring to stretch, and after the moving ring driving assembly stops driving, the first moving ring is reset under the elastic force of the tension spring to clamp the wire; the movement of the first moving ring drives the first clamping block to move along the radial circumferential direction of the main shaft, so that the wire clamping position between the first clamping block and the second clamping block is closer to the fixed end of the main shaft skeleton, thereby controlling the length of the wire head or tail.

[0010] A further solution is that a first limiting ring and a second limiting ring are provided on the radial outer side wall of the main shaft, the first movable ring is provided between the first limiting ring and the second limiting ring, and the second clamping block is fixedly provided on the second limiting ring.

[0011] It can be seen that the first limiting ring and the second limiting ring limit the moving direction of the first movable ring, ensuring the accuracy of the moving direction of the first clamping block driven by the movement of the first movable ring, so that the first clamping block and the second clamping block can clamp the wire accurately and stably.

[0012] A further solution is that the moving ring drive assembly includes a first driving sleeve, a first driving ring and a wire clamping drive device, the first driving sleeve is sleeved outside the main shaft, the first driving sleeve is provided with a first groove along the circumference of the main shaft, the main shaft passes through the first driving ring, a first connecting block is provided on the side wall of the first driving ring facing the main shaft, the first connecting block is located in the first groove, and the wire clamping drive device drives the first driving ring to move axially along the main shaft; a first inclined surface is provided on the end of the first driving sleeve close to the first moving ring, a protruding block is provided on the side wall of the first moving ring away from the main shaft, and the first inclined surface is adjacent to the protruding block.

[0013] It can be seen that since the first connecting block of the first drive ring is located in the first groove of the first drive sleeve, when the main shaft rotates to drive the first drive sleeve to rotate, the first movable ring can maintain its state to avoid mutual interference; when the wire clamping drive device drives the first drive ring to move, it can drive the first drive sleeve to move. Since the inclined surface on the first drive sleeve is adjacent to the raised block on the first movable ring, the movement of the first drive sleeve drives the movement of the first movable ring, and drives the first clamping block to move away from the second clamping block. This structure realizes the rotation of the main shaft while realizing the movement of the first drive sleeve on the main shaft, and the movement of the main shaft and the movement of the first drive sleeve do not interfere with each other.

[0014] A further solution is that the wire clamping assembly includes a third clamping block, a fourth clamping block, a second movable ring and a third limiting ring, the second movable ring and the third limiting ring are respectively arranged outside the main shaft, the second movable ring is arranged between the second limiting ring and the third limiting ring, the movable ring driving assembly drives the second movable ring to move along the circumferential direction of the main shaft, the third clamping block is arranged on the second movable ring, and the fourth clamping block is arranged on the third limiting ring.

[0015] It can be seen that since the second movable ring is arranged between the second limit block and the third limit ring, the movement of the second movable ring can be limited, and the movement of the second movable ring drives the third clamping block to move toward the fourth clamping block. The first clamping block and the second clamping block clamp the end of the wire, and the third clamping block and the fourth clamping block clamp the end of the wire, which is convenient for subsequent wire cutting.

[0016] A further solution is that a guide block is provided on the radial outer wall of the main shaft, the guide block is provided between the third limiting ring and the skeleton fixed end of the main shaft, an avoidance step is provided on the second clamping block, and the guide block is located in the avoidance step; a guide end face is provided on the guide block, and the skeleton fixed end of the main shaft is located on the guide end face.

[0017] It can be seen that the fixed end of the main shaft skeleton is located on the guide end face, and the bend formed on the guide block and the guide end face guide the wire, so that the wire is kept in a certain position for winding, which makes the winding effect better.

[0018] A further solution is that a hollow portion is provided inside the main shaft along the axial direction of the main shaft, an opening is provided at the fixed end of the main shaft skeleton, the opening is connected to the hollow portion, a clamping assembly is provided in the hollow portion, the clamping assembly includes at least two clamping plates, at least two clamping plates are respectively provided with second inclined surfaces, the second inclined surfaces are respectively adjacent to the inner side walls of the main shaft, and the mobile driving assembly drives the clamping plate to pass through the opening.

[0019] It can be seen that the clamping assembly is arranged in the main shaft. When the mobile driving assembly drives the clamping piece to pass through the opening, the distance between the two clamping pieces becomes larger, and the skeleton is located between the two clamping pieces. The mobile driving assembly drives the clamping piece to move in the opposite direction. The two clamping pieces clamp the skeleton and retract into the hollow part of the main shaft, thereby fixing the skeleton. The skeleton is clamped by the clamping assembly, and there is no requirement for the shape and structure of the skeleton, thereby improving the application degree of the device.

[0020] A further solution is that the mobile drive component includes a translation drive component, the translation drive component includes a translation drive device, a second drive ring, a second drive sleeve and a drive rod, the drive rod is arranged in the hollow portion, a slide groove is arranged on the main shaft, the slide groove is connected with the hollow portion, the second drive sleeve is sleeved outside the main shaft, a connecting rod is arranged on the side wall of the second drive sleeve facing the main shaft, the connecting rod passes through the slide groove and the drive rod, the second drive sleeve is provided with a second groove along the circumference of the main shaft, the main shaft passes through the second drive ring, and the second drive ring is provided with a second connecting block towards the second drive sleeve, the second connecting block is located in the second groove, and the translation drive device drives the second drive ring to move axially along the main shaft.

[0021] It can be seen that the translation drive device drives the second drive ring to move, which drives the second drive sleeve to move. Since the connecting rod on the second drive sleeve passes through the slide groove and the drive rod, the movement of the second drive sleeve drives the drive rod to move. Since the clamping assembly is arranged on the drive rod, the clamping and release of the clamping assembly are realized.

[0022] A further solution is that there are two main shafts, the two main shafts are arranged in parallel, and a wire clamping assembly is provided on the outer side wall of each main shaft; the mobile drive assembly includes a rotation drive assembly, the rotation drive assembly includes a rotation drive device and a transmission belt, the two main shafts are respectively connected to the transmission belts, and the rotation drive device drives one of the main shafts to rotate.

[0023] It can be seen that the two main shafts rotate simultaneously to carry out the winding process of the two skeletons, which effectively improves the work efficiency.

[0024] To achieve the above second objective, the winding device provided by the present invention includes the winding spindle assembly as described above. BRIEF DESCRIPTION OF THE DRAWINGS

The side wall of the groove 1112 can be arc-shaped, matching the I-shaped skeleton that is circular when viewed from above. The vibration plate 101 drives the skeleton on the linear track 102 to pass through the opening 1113 and enter the groove 1112. The side plate with a larger width in the I-shaped skeleton is placed on the mounting plate, and the middle shaft and the side wall with a smaller width are suspended in the groove 1112. The lifting assembly 112 is used to lift the skeleton in the groove 1112, so that the side plate with a larger width in the skeleton can move away from the mounting plate 1111, so that the winding spindle assembly 2 can grab the skeleton. The ejector assembly 112 includes an ejector drive cylinder 1121 and two ejector rods 1122. The two ejector rods 1122 are respectively located in two grooves 1112 in a one-to-one correspondence. The ejector drive cylinder 1121 drives the two ejector rods 1122 to move in the grooves 1112 at the same time. The feed drive assembly 113 includes a motor 1132 and a screw rod 1131. The motor 1132 drives the screw rod 1131 to rotate, and the screw rod 1131 is connected to the feed block 1111. The winding spindle assembly 2 is used to fix the skeleton and drive the skeleton to rotate for winding. The wire cutting assembly 12 is used to cut the wire on the winding spindle assembly 2. In this embodiment, the wire cutting assembly 12 includes two pneumatic scissors 121. The wire cutting assembly 12 is arranged between the winding spindle assembly 2 and the wire nozzle assembly 13. The wire nozzle assembly 13 is used to guide the direction of the wire. The nozzle assembly 13 includes two nozzles 131, two wire pressing assemblies and a nozzle driving assembly 133. In this embodiment, the nozzles 131 extend in the horizontal direction. One nozzle 131 corresponds to one wire pressing assembly. The wire pressing assembly includes two pressing blocks 132, and the wire passes between the two pressing blocks 132. The nozzle driving assembly 133 drives the nozzle to move in three directions of X, Y and Z.

[0035] In this embodiment, the jig feeding assembly 14 includes a first conveying track 141 and a first track driving assembly 142. The first conveying track 141 is used for an empty jig. The empty jig is provided with a plurality of placement grids. The placement grids are used to place the coils that have been wound. The first track driving assembly 142 drives the empty jig on the first conveying track 141 to move along the extension direction of the first conveying track 141. The unloading assembly 15 includes a second conveying track assembly and a clamping assembly. The second conveying track assembly includes a second conveying track 151 and a second track driving assembly. The second conveying track 151 is used to convey the jig. The second track driving assembly drives the jig to move along the direction of the second conveying track 151. The extension direction of the lead screw 1131, the first conveying track 141, and the extension direction of the second conveying track 151 are parallel to each other. The second conveying track 151 is arranged between the first conveying track 141 and the feeding assembly 11. The material clamping assembly includes a clamping assembly 152 and a clamping driving assembly 153 . The clamping assembly 152 clamps the fixture by two clamping blocks 1521 that can move toward or away from each other. The clamping driving assembly 153 drives the clamping assembly 152 to move between the first conveying track 141 and the second conveying track 151 .

[0036] The working process of the winding device is as follows: the vibration disk 101 drives the skeleton to move to the feeding assembly 11, and the feeding assembly 11 drives the skeleton to move to the winding spindle assembly 2. The operator passes the wire through the wire pressing assembly and the wire nozzle 131 in turn, and the wire clamping assembly on the winding spindle assembly 2 clamps the wire to start winding. At the same time, the first conveying track assembly 14 conveys the empty jig, and the clamping assembly 152 moves the empty jig to the second conveying track 151. After the skeleton is wound, the wire cutting assembly 12 cuts the wire, and the winding spindle assembly 2 places the coil on the empty jig. After the empty jig is full, the clamping assembly 152 moves the full jig from the second conveying track 151 to the first conveying track 141 for unloading.

[0037] See also Figure 3 The winding spindle assembly 2 includes a mounting frame 21, a rotating spindle assembly 3, a wire clamping assembly 4 and a spindle moving driving assembly 5. The mounting frame 21 is arranged on the mounting platform 10, and a through slot 211 is arranged on the mounting frame 21. The rotating spindle assembly 3 and the spindle moving driving assembly 5 are respectively arranged on the mounting platform 21, and the rotating spindle assembly 3 extends in the vertical direction and passes through the through slot 211. In this embodiment, the spindle moving driving assembly 5 is arranged on the side wall of the mounting frame 21 away from the mounting platform 10. When the spindle moving driving assembly 5 drives the rotating spindle assembly 3 to move along the first direction X, the first direction X intersects with the extension direction of the first conveying track 141. The spindle moving driving assembly 5 drives the rotating spindle assembly 3 to move in the horizontal direction and the vertical direction through the structure connected by two groups of motors and the screw rod.

[0038] See also Figure 4In this embodiment, the rotating spindle assembly 3 includes a fixed plate 31, two spindles 6 and a mobile driving assembly. The mobile driving assembly drives the two spindles 6 to rotate synchronously. The mobile driving assembly is arranged on the fixed plate 31, and the two spindles 6 are arranged in parallel.

The rotation driving assembly 8 includes a rotation driving device 81 and a transmission belt 82. The transmission belt 82 is connected to the two spindles 6 respectively. The rotating driving device 81 is a rotating motor. The rotating driving device 81 drives one spindle 6 to rotate, and drives the other spindle 6 to rotate through the transmission belt 82. The two spindles 6 rotate simultaneously to perform the winding process, which effectively improves the work efficiency. In this embodiment, a rotating block 61 is fixedly connected to one of the main shafts 6, and the rotating block 61 is sleeved outside the main shaft 6.

A photoelectric sensor 32 is provided on the fixed plate 31, and a groove 321 is provided on the photoelectric sensor 32. When the main shaft 6 rotates, the detection piece 611 passes through the groove 321 of the photoelectric sensor 32, and the number of rotations of the main shaft 6 is detected by this detection structure.

[0039] See also Figure 5 A hollow portion 62 is provided in the spindle 6 along the axial direction of the spindle 6, and an opening 631 is provided at the frame fixing end 63 of the spindle 6. The opening 631 is connected to the hollow portion 62, and the frame is fixed on the frame fixing end 63 of the spindle 6. A clamping assembly 9 is provided in the hollow portion 62, see Figure 6 The clamping assembly 9 includes a connecting shaft 91 and three clamping pieces 92. The three clamping pieces 92 are arranged on the first axial end of the connecting shaft 91 and are arranged equidistantly along the circumference of the connecting shaft 91. A second inclined surface 921 is respectively arranged on each clamping piece 92 along the main shaft 6. The second inclined surface 921 is respectively adjacent to the inner side wall of the hollow part 62 in the main shaft 6. The translation drive assembly 7 drives the clamping piece 92 to pass through the opening 631. After the three clamping pieces 92 pass through the opening 631, the three clamping pieces 92 are dispersed, and the distance between each other becomes larger. The skeleton enters between the three clamping pieces 92. When the translation drive assembly 7 drives the clamping piece 92 to move in the reverse direction, the clamping piece 92 is moved closer and contracted into the hollow part 62 of the main shaft 6, thereby fixing the skeleton. The skeleton is clamped by the clamping assembly 9, and there is no requirement for the shape and structure of the skeleton, which improves the application degree of the device. In addition, the hollow part 62 in the main shaft 6 limits the clamping assembly 9 to ensure the stability of the clamping assembly 9 fixing the skeleton.

[0040] The fixed plate 31 is provided with a cylinder mounting plate 33 protruding from the side wall on which the sensor 32 is provided, and the cylinder mounting plate 33 is provided below the sensor 32. The translation drive assembly 7 includes two translation drive devices 71, a second drive ring 72, a second drive sleeve 73 and a drive rod 74.

The drive rod 74 is provided in the hollow portion 62, and the clamping assembly 9 is provided on the drive rod 74. The main shaft 6 is provided with a slide groove 63, which is connected to the hollow portion 62; and the drive rod 74 is provided with a through hole 741. The second drive sleeve 73 is sleeved outside the main shaft 6, and a connecting rod 731 is provided on the side wall of the second drive sleeve 73 facing the main shaft 6, and the connecting rod 731 passes through the slide groove 63 and the through hole 741 on the drive rod 74. The second drive sleeve 73 is provided with a second groove 732 along the circumference of the main shaft 6. The main shaft 6 penetrates the second drive ring 72. The second drive ring 72 is provided with two second connection blocks 721 toward the second drive sleeve 73. The two second connection blocks 731 are respectively located in the second groove 732. The translation drive device 71 drives the second drive ring 72 to move along the axial direction of the main shaft 6. When the translation drive device 71 drives the second drive ring 72 to move, the second drive sleeve 73 is driven to move. Since the connecting rod on the second drive sleeve 73 penetrates the slide groove 63 and the drive rod 74, the movement of the second drive sleeve 73 drives the drive rod 74 to move. Since the clamping assembly 9 is connected to the drive rod 74, the clamping and release of the clamping assembly 9 are realized. The rotation of the main shaft 6 drives the second drive sleeve 73 to rotate, and the second connecting block 721 on the second drive ring 72 always remains stationary in the second groove 7321. When the translation drive device 71 drives the second drive ring 72 to move, the second drive sleeve 73 is driven to move through the second connecting block 721, so that the connecting rod 731 moves in the slide groove 63, thereby realizing the movement of the drive rod 74, driving the clamping assembly 9 to clamp and release the skeleton, thereby realizing the complementary interference between the rotation of the main shaft 6 and the axial movement of the drive rod 74 in the main shaft 6 along the main shaft 6.

[0041] In this embodiment, the connecting shaft 91 is inside the moving sleeve 90, the second inclined surface 921 on the clamping piece 92 is arranged outside the moving sleeve 90, the moving sleeve 90 is arranged inside the hollow part 62, and the moving sleeve 90 is connected to the driving rod 74. Steps are arranged on the side walls of the moving sleeve 90 and the hollow part 62, respectively, and a spring 70 is abutted between the steps of the moving sleeve 90 and the steps of the hollow part 62. When the driving rod 74 drives the moving sleeve 90 to move, the spring 70 is compressed. When the translation driving device 71 stops driving, under the elastic force of the spring 70, the driving rod 74 drives the clamping assembly 9 to reset.

[0042] In this embodiment, a limiting groove 911 is provided on the axial second end of the connecting shaft 91, and a limiting rod 64 is provided in the hollow portion 62 in the main shaft 6 along the radial direction of the main shaft 6. The limiting rod 64 is provided between the connecting shaft 91 and the driving rod 74, and the limiting rod 64 can be located in the limiting groove 911. When the translation drive assembly 7 drives the driving rod 74 to move, the connecting shaft 91 moves away from the limiting rod 64, and the moving length of the driving rod 74 can be controlled according to the length of the slide groove along the axial direction of the main shaft 6, thereby controlling the degree of dispersion in the clamping assembly 9; when the translation drive assembly 7 drives the driving rod 74 to move in the reverse direction, the connecting shaft 91 moves toward the limiting rod 64, and after the limiting rod 64 enters the limiting groove 911, the connecting shaft 91 stops moving. The setting position of the limiting rod 64 controls the moving length of the connecting shaft 91, and ensures that while the skeleton is firmly clamped, a sufficient part of the skeleton extends out of the main shaft 6 for winding.

[0043] See also Figure 7 , one clamping assembly 4 is correspondingly arranged on the radial outer side wall of one main shaft 6. The clamping assembly 4 comprises a first clamping block 41, a second clamping block 42, a third clamping block 43, a fourth clamping block 44 and a clamping block driving assembly 45. The second clamping block 42 and the fourth clamping block 44 are respectively fixedly arranged on the radial outer side wall of the main shaft 6. The clamping block driving assembly 45 drives the first clamping block 41 to move toward or away from the second clamping block 42, and the third clamping block 43 to move toward or away from the fourth clamping block 44. The first clamping block 41 and the third clamping block 43 move along the circumferential direction of the main shaft 6.

[0044] In this embodiment, the clamp block driving assembly 45 includes two tension springs, a first limiting ring 451, a first moving ring 452, a second limiting ring 453, a second moving ring 454, a third limiting ring 455 and a moving ring driving assembly 46.

The first clamp block 41, the second clamp block 42, the third clamp block 43 and the fourth clamp block 44 extend respectively toward the frame fixed end 63 of the main shaft 6. The moving ring driving assembly 46 drives the first moving ring 452 and the second moving ring 454 to move in the same direction along the circumference of the main shaft 6, so that the first clamp block 41 moves away from the second clamp block 42, and the third clamp block 43 moves away from the fourth clamp block 44, so that the distance between the two groups of clamp blocks is opened, so that the wires can enter between the two groups of clamp blocks respectively. One tension spring is respectively connected to the first movable ring 452 and the main shaft 6, and the other tension spring is respectively connected to the second movable ring 454 and the main shaft 6. When the first movable ring 452 and the second movable ring 454 move, the two tension springs are respectively stretched. When the movable ring driving assembly 46 stops driving, under the tension of the tension springs, the first movable ring 452 and the second movable ring 454 are reset, so that the first clamping block 41 moves toward the second clamping block 42, and the third clamping block 43 moves toward the fourth clamping block 44, thereby clamping the wire.

[0045] The movable ring drive assembly 46 includes a first drive sleeve 461, a first drive ring 462, a third drive ring 463 and two wire clamping drive devices 464. The first drive sleeves 461 are respectively sleeved on the outside of the main shaft 6. The first drive sleeves 461 are provided with first grooves 4611 along the circumference of the main shaft 6. The main shaft 6 passes through the first drive ring 462. Two first connecting blocks 4621 are provided on the side wall of the first drive ring 462 facing the main shaft 6. The two first connecting blocks 4621 are respectively located in the first grooves 4611. The wire clamping drive device 464 drives the first drive ring 462 to move axially along the main shaft 6. The third driving ring 463 is fixedly connected to the first driving sleeve 461, and the third driving ring 463 is sleeved outside the main shaft 6. A first inclined surface 4631 is provided on one end of the third driving ring 463 close to the first moving ring 452, and a first protruding block 4521 is provided on the side wall of the first moving ring 452 away from the main shaft 6, and the first inclined surface 4631 is adjacent to the first protruding block 4521. A driving block 465 is provided on the outer side wall of the third driving ring 463, and the driving block 465 extends to the second moving ring 454, and a second protruding block 4541 is provided on the second moving ring 454. The driving block 465 is provided with a third inclined surface 4651, and the third inclined surface 4561 is adjacent to the second protruding block 4541. In this embodiment, the first protruding block 4521 and the second protruding block 4541 are cylindrical, respectively, and the first inclined surface 4631 and the third inclined surface 4561 have the same inclination direction. Since the first connecting block 4621 of the first driving ring 462 is located in the first groove 4611 of the first driving sleeve 461, when the main shaft 6 rotates to drive the first driving sleeve 461 to rotate, the first movable ring 452 can remain in a stopped state to avoid interfering with the rotation of the main shaft 6; when the wire clamping drive device 464 drives the first driving ring 462 to move, it can drive the first driving sleeve 461 to move. Since the inclined surface on the first driving sleeve 461 is adjacent to the raised block on the first movable ring 452, the movement of the first driving sleeve 461 drives the movement of the first driving ring 462, and drives the first clamping block 41 to move away from the second clamping block 42. This structure realizes the rotation of the main shaft 6 while realizing the movement of the first driving sleeve 461 on the main shaft 6, and the movement of the main shaft 6 and the movement of the first driving sleeve 461 do not interfere with each other.

[0046] The third drive ring 463 is provided with a slide groove 4562, and the main shaft 6 is provided with a limit column 66, which moves in the slide groove along the axial direction of the main shaft 6. The setting of the limit column 66 limits the moving distance of the first drive sleeve 461 to prevent the first clamping block 41 from moving too far, making it difficult to clamp the wire or reset.

[0047] The wire clamping driving device 464 is a cylinder, and the wire clamping driving device 464 and the translation driving device are respectively arranged on two side walls of the cylinder mounting plate 33 that are away from each other.

[0048] Two guide blocks 67 are protruded on the radial outer wall of the main shaft 6. The protrusion height of the guide block 67 is greater than the first limit ring 451. One guide block is correspondingly located at the first clamp block 41 and the second clamp block 42, and the other guide block 67 is correspondingly located at the third clamp block 43 and the fourth clamp block 44. The first clamp block 41 and the second clamp block 42 are respectively provided with avoidance steps 40, and the guide block 67 is located at the avoidance steps 40. A guide end face 671 is provided on the guide block 67 near the skeleton fixed end 63 of the main shaft 6. The skeleton fixed end 63 of the main shaft 6 is located on the guide end face 671. The bend 672 and the guide end face 671 formed on the guide block 67 guide the wire, so that the wire is kept in a certain position for winding, so that the winding effect is better.

[0049] The main shaft 6 is used to fix the skeleton, which can be fixed by penetration or cable nozzle; the mobile driving component drives the main shaft 6 to rotate, and the rotation of the main shaft 6 drives the rotation of the skeleton, which is convenient for the skeleton to be wound; the wire clamping component 4 is arranged on the outer wall, and the rotating main shaft 6 component 3 and the wire clamping component 4 are integrated into one, reducing the setting of components in the winding device, so that the layout of the winding device components has a wider operating space to adapt to the winding process of skeletons of more different shapes; the operator can set the position of the wire clamping component 4 on the outer wall of the main shaft 6 according to the required length of the wire end. When the first clamping block 41 and the second clamping block 42 are respectively located in the same plane as the skeleton fixed end 63 of the main shaft 6, while ensuring that the skeleton fixed end 63 of the main shaft 6 firmly fixes the skeleton, the distance between the wire clamping component 4 and the skeleton fixed end 63 of the main shaft 6 is the shortest, so that the length of the wire end is short, which better guarantees the subsequent welding effect of the coil. When winding, after the translation drive component 7 drives the clamping component 9 to clamp the skeleton, the moving ring drive component 46 drives the first clamp block 41 and the second clamp block 42 to clamp the wire, and the rotation drive component drives the main shaft 6 to rotate to start winding; after the winding is completed, the moving ring drive component 46 drives the first clamp block 41 to move away from the second clamp block 42, and the third clamp block 43 moves away from the fourth clamp block 44, and the wire falls from between the first clamp block 41 and the second clamp block 42. Under the guidance of the wire nozzle component 13, the wire enters the third clamp block 43 and the fourth clamp block 44, the wire cutting component 12 cuts the wire, and the main shaft 6 moving component drives the main shaft 6 to move to the second conveying track 151, and the skeleton is placed on the empty jig, and the material is unloaded after the empty jig is full.
