Description

Technical Field

[0001] The present invention relates to the field of coil preparation and processing equipment, and specifically relates to a folding line clamping component, a folding line mechanism, and a multi-axis flat wire winding and folding line device. Background Art

[0002] When making a flat wire coil, it is necessary to perform multiple folding lines and tangents on the connecting feet of the flat coil. During the entire process of making the flat wire coil from winding, folding line, tangent, and blanking, the preparation device is provided with components corresponding to the above process steps. Among them, during the folding line process, since the folding line can include multiple folding lines, one folding line corresponds to one folding line component, and multiple folding line components are independent of each other. Multiple folding line components and tangents are arranged around the outer periphery of the fixing seat for fixing the flat wire coil. When only one flat wire coil can be fixed on the fixing seat, only one coil can perform the folding line step, which affects the working efficiency. If multiple fixing seats are provided on the device, one fixing seat corresponds to fixing one coil, so that multiple working blocks are also provided on the corresponding folding line components and tangent components, making the components in the winding and folding line device more complex and occupying more space. Summary of the Invention

[0003] The first object of the present invention is to provide a folding line clamping component that can effectively improve efficiency and has a simpler structure.

[0004] The second object of the present invention is to provide a folding line mechanism including the above folding line clamping component.

[0005] The third object of the present invention is to provide a multi-axis flat wire winding and folding line device including the above folding line mechanism.

[0006] To achieve the above first object, the folding line clamping component provided by the present invention includes a mounting plate, a first clamping component, a second clamping component, and a clamping rotation driving device. A feeding station and a folding line station are provided on the mounting plate. One of the first clamping component and the second clamping component is arranged at the feeding station, and the other is arranged at the folding line station. The clamping rotation driving device drives the mounting plate to rotate; the first clamping component includes a first moving block, a second moving block, and a moving block moving driving device. A first clamping block and a second clamping block are arranged on the first moving block, and a third clamping block and a fourth clamping block are arranged on the second moving block. A first clamping part is formed between the first clamping block and the third clamping block, and a second clamping part is formed between the second clamping block and the fourth clamping block. The moving block moving driving device simultaneously drives the third clamping block to move towards the first clamping block and the fourth clamping block to move towards the second clamping block, and the first clamping part and the second clamping part are arranged collinearly.

[0007] It can be seen from the above scheme that since the mounting plate is provided with two clamping assemblies, when folding, the clamping assembly located at the discharge station clamps the coil after loading, and the coil clamped by the clamping assembly located at the folding station is performing the folding process step, and the coils on the two stations work simultaneously, effectively improving work efficiency; when the clamping assembly is working, the moving block moves the driving device to drive the third clamping block toward the first clamping block and the fourth clamping block toward the second clamping block, so that the first clamping block and the third clamping block, the second clamping block and the fourth clamping block respectively clamp the coil simultaneously, so that there are two clamping parts on one clamping assembly at the same time, and two clamping assemblies are arranged on the mounting plate, so that there are four clamping parts on the mounting plate, and the coils on the four clamping parts work simultaneously, further improving work efficiency; a discharge station and a folding station are arranged on the mounting plate, and the distance between the components corresponding to the discharge and folding is pulled apart, so that the layout of each component is more reasonable and simple.

[0008] A further solution is that the first clamping part and the second clamping part are arranged in the same line along the moving direction of the third clamping block; the first moving block is provided with a first mounting bar and a moving track, the first clamping block and the second clamping block are respectively arranged on the first mounting bar, and the moving track is located between the second clamping block and the first mounting bar; the second moving block is provided with a second mounting bar, the third clamping block and the fourth clamping block are arranged on the second mounting bar, and the second mounting bar is arranged in the moving track.

[0009] It can be seen that the second mounting bar of the second moving block moves in the moving track to guide the movement of the second moving block, ensure the accuracy of the moving direction of the second moving block, clamp the coil more accurately, and the first clamping part and the second clamping part are colinearly arranged along the moving direction of the third clamp, so that the first moving block and the second moving block are integrated into one, making the volume of the folding line clamping assembly smaller.

[0010] A further solution is that a limiting block is provided on the side wall of the second clamping block facing the movable track, and a limiting groove is provided on the side wall of the second mounting strip facing the limiting block, and the limiting block moves in the limiting groove.

[0011] It can be seen that since the limit block is arranged in the limit slot, when the second moving block moves, the limit block moves in the limit slot, and the length of the limit slot along the moving direction of the third clamping block can be used to limit the moving range of the second moving block.

[0012] A further solution is that the second clamping block and the first mounting strip are respectively connected to the connecting block, and an avoidance space is provided between the second clamping block and the first mounting strip along the moving direction of the third clamping block, and the second mounting strip is located in the moving track; a connecting seat is provided on the side wall of the second mounting strip facing away from the second clamping block, the connecting seat is connected to the moving drive device of the moving block, and the connecting seat is located in the avoidance space.

[0013] It can be seen that since the connecting seat of the second moving block is located within the avoidance vacancy, the second moving block is embedded on the first moving block, making the width of the clamping assembly smaller and the volume smaller.

[0014] A further solution is that the first moving block is provided with a first fixing seat and a second fixing seat. The first fixing seat is located between the first clamping block and the third clamping block, and the second fixing seat is arranged between the second clamping block and the fourth clamping block. A first gap is respectively provided between the fixed end of the first fixing seat and the first clamping block and the third clamping block, and a second gap is respectively provided between the fixed end of the second fixing seat and the second clamping block and the fourth clamping block.

[0015] It can be seen that the first fixing seat is located within the first clamping portion, and the second fixing seat is located within the second clamping portion. The first fixing seat and the second fixing seat are respectively used for placing coils. When the two clamping blocks clamp the coils on the fixing seats, the first gap and the second gap respectively correspond to the two connecting feet on the coils, facilitating the folding block to enter the gaps to fold the connecting feet, and the setting of the gaps can limit the folding block.

[0016] To achieve the above second object, the folding mechanism provided by the present invention includes the folding clamping assembly, the first folding assembly, and the second folding assembly as described above. The first folding assembly includes a first folding driving assembly and a first folding block. The first folding driving assembly drives the first folding block to move towards or away from the folding station. The second folding assembly includes a second folding driving assembly and a second folding block. The second folding driving assembly drives the second folding block to move towards or away from the folding station. The moving direction of the first folding block intersects with the moving direction of the second folding. The first folding assembly and the second folding assembly are respectively located on two opposite sides of the mounting plate, and the folding station is arranged between the first folding assembly and the second folding assembly.

[0017] It can be seen that the two folding assemblies are respectively located on two opposite sides of the folding station, realizing folding in different directions and completing multiple foldings.

[0018] A further solution is that the first folding driving assembly includes a vertical driving assembly and a horizontal driving assembly. The vertical driving assembly drives the first folding block to move in the vertical direction, and the horizontal driving assembly drives the first folding block to move in the vertical direction. Two driving pieces are provided on the first folding block. Pushing blocks are respectively provided on the side walls of the two driving pieces facing the folding clamping assembly 8. A folding step is formed between the protruding pushing block and the driving piece, and the first clamping portion can be located on the folding step.

[0019] It can be seen that since the first broken line block can move in the vertical and horizontal directions, the first broken line block can perform two broken lines. When the first broken line block moves in the vertical direction, the wire pushing block pushes the connecting foot part to extend in the vertical direction. When the second broken line block moves in the horizontal direction, the coil on the first clamping part gradually enters the broken line step, and the connecting foot part that originally extended in the vertical direction is extended towards the horizontal direction. The setting of the broken line step can also limit the displacement of the wire pushing block moving in the horizontal direction.

[0020] A further solution is that the second broken line block is a cutting knife, the second broken line assembly includes a lower cutting knife assembly, the broken line clamping assembly is arranged between the second broken line block and the lower cutting knife assembly, the lower cutting knife assembly includes a lower cutting knife driving assembly and a lower cutting knife block, and the lower cutting knife driving assembly drives the lower cutting knife block to move towards the second broken line block; a groove is arranged on the side wall of the lower cutting knife block facing the second broken line block, a cutting edge is formed on the lower cutting knife block, the second broken line block enters the groove, and the cutting edge on the second broken line block is arranged in cooperation with the cutting edge on the lower cutting knife block.

[0021] It can be seen that since the second broken line block is a cutting knife, when the second broken line block and the lower cutting knife move towards each other respectively, while the second broken line block drives the connecting foot part to bend, it also drives the connecting foot part to enter the groove of the lower cutting knife at the same time, realizing bending while completing the wire cutting, combining the two process steps, and further improving the working efficiency with a simpler structure of the second broken line assembly.

[0022] A further solution is that a first inclined surface and a second inclined surface are arranged on the side wall of the second broken line block facing the broken line clamping assembly, and the first inclined surface and the second inclined surface are arranged oppositely; a third inclined surface and a fourth inclined surface are arranged on the side wall of the lower cutting knife block facing the groove, the first inclined surface and the third inclined surface are opposite and parallel, and the second inclined surface and the fourth inclined surface are opposite and parallel.

[0023] It can be seen that the arrangement of the inclined surfaces on the second broken line block and the lower cutting knife can make the connecting foot part have an inclined cutting surface while cutting off the connecting foot part of the coil.

[0024] To achieve the above-mentioned third purpose, the multi-axis flat wire winding and breaking device provided by the present invention includes the above-mentioned breaking mechanism. Description of the Drawings

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiments

[0045] The multi-axis flat wire folding and winding device of the present invention is applied to the winding and folding process of flat wire coils. Such flat wire coils are relatively small in volume, and flat wires are wound on the skeleton in a stacked manner. In the multi-axis flat wire folding and winding device of the present invention, a feeding station and a folding station are provided in the folding clamping component. While the clamping component at the feeding station fixes the material, the coil clamped by the clamping component at the folding station is folded. The coils at the two stations work simultaneously, effectively improving the working efficiency and making the structure of the device simpler, avoiding the device being too large in volume.

[0046] See Figure 1 , the multi-axis flat wire winding and folding device includes a feeding component 1, a wire feeding component 2, a winding component 3, a folding mechanism 4 and a blanking component 5. The feeding component 1 is used for feeding the skeleton and transferring the material between the feeding component 1 and the winding component 3, and between the winding component 3 and the folding mechanism 4; the wire feeding component 2 is used for guiding the flat wire; the winding component 3 is used for winding the flat wire on the skeleton to form a flat wire coil; the folding mechanism 4 is used for folding the connecting feet on the coil multiple times; the blanking component 5 is used for loading the folded coil onto a tray.

[0047] The feeding component 1 includes a skeleton feeding component 11 and a feeding conveying component 12. The skeleton feeding component 11 includes a vibrating disk 111 and a linear track 112. The linear track 112 is connected to the vibrating disk 111. The skeletons are concentrated in the vibrating disk 111, and the vibrating disk 111 drives the skeletons to be arranged orderly on the linear track 112 through vibration. The feeding conveying component 12 is used to move the coil on the linear track 112 into the winding component 3. See Figure 2, the loading and conveying assembly 12 includes a mounting plate 121, four conveying fixing assemblies, and a conveying driving assembly. The four conveying fixing assemblies are arranged on the mounting plate 121, and the conveying driving assembly drives the mounting plate 121 to move between the linear track 112 and the winding assembly 3, driving the four conveying fixing assemblies to move. The structures of the four conveying fixing assemblies are the same. The conveying fixing assembly includes a suction nozzle assembly and a fixing clamp assembly. Along the vertical direction, the suction nozzle assembly is arranged above the fixing clamp assembly. In this embodiment, the suction nozzle assembly includes a suction nozzle fixing seat 122, a suction nozzle mounting rod 123, and a suction nozzle 124. The suction nozzle fixing seat 122 is arranged on the mounting plate 121, the suction nozzle mounting rod 123 is mounted on the suction nozzle fixing seat 122, and the suction nozzle 124 is mounted on the side wall of the suction nozzle mounting rod 123 facing the fixing clamp assembly. The suction nozzle fixing seat 122 and the suction nozzle mounting rod 123 are respectively provided with air pipes, and the air pipes are connected to the suction nozzle 124. The fixing clamp assembly includes a jaw cylinder 125, a first clamping block 126, and a second clamping block 127. The suction nozzle 124 extends through the skeleton clamping part 128 between the first clamping block 126 and the second clamping block 127. The structure of the first clamping block 126 is the same as that of the second clamping block 127. On the ends of the first clamping block 126 and the second clamping block 127 facing the suction nozzle 124, there are respectively provided protruding blocks 129, and the protruding blocks 129 are respectively arranged on the side walls of the first clamping block 126 and the second clamping block 127 facing away from the suction nozzle mounting rod 123. When the conveying fixing assembly fixes the skeleton, the suction nozzle 124 sucks the skeleton tightly, and the first clamping block 126 and the second clamping block 127 clamp the skeleton. The skeleton is fixed in a combined manner by two fixing methods, improving the stability of the skeleton. The setting of the protruding blocks 129 can increase the contact area between the clamping block and the skeleton, further ensuring the stability of the skeleton.

[0048] The conveying driving assembly includes a mounting plate 1210, a servo motor 1211, and a lead screw 1212. The servo motor 1211 and the lead screw 1212 are arranged on the mounting plate 1210. The mounting plate 1210 is connected to the lead screw 1212. The servo motor 1211 drives the lead screw 1212 to rotate, driving the mounting plate 1210 to move, thereby conveying the skeleton. On the side wall of the mounting plate 121 facing the mounting plate 1210, there are provided a plurality of detection pieces 1213. On the side wall of the mounting plate 1210 facing the mounting plate 121, there are provided a plurality of detectors 1214. The detector 1214 is provided with a groove 1215, and the detection piece 1213 can pass through the groove 1215. The cooperation setting of the detection piece 1213 and the detector 1214 is used to detect the position where the skeleton is conveyed.

[0049] See Figure 3 , the wire feeding assembly 2 includes a wire feeding driving assembly 21 and a wire feeding block assembly 22. The wire feeding driving assembly drives the wire feeding block assembly 22 to move along the XYZ directions. In each direction, a structure in which the motor 211 drives the lead screw 212 to move to drive the wire feeding block assembly 22 to move is respectively adopted, and the axial directions of the lead screws 212 in the three directions are different. SeeFigure 4 , the wire feeding block assembly 22 includes a first wire feeding block 221 and a second wire feeding block 222. Along the vertical direction, the first wire feeding block 221 is fixedly arranged on the second wire feeding block 222. A wire routing channel 223 is arranged between the first wire feeding block 221 and the second wire feeding block 222. The wire routing channel 223 is inclined downward along the vertical direction towards the winding assembly 3. In this embodiment, an extending section 2211 is arranged on the first wire feeding block 221 based on the second wire feeding block 222. The extending section 2211 is located above the outlet 2231 of the wire routing channel 223, and the extending section 2211 extends horizontally along the side wall of the wire routing channel 223. When the wire moves in the wire routing channel 223, the side wall extending horizontally on the extending section 2211 limits the wire, so that the wire extending out of the wire routing channel 223 extends horizontally as much as possible, thereby making the winding stacking effect better.

[0050] A cutting component 6 is arranged between the wire feeding component 2 and the winding component 3. The cutting component 6 is used for cutting the wire between the wire feeding component 2 and the winding component 3. See Figure 5 , the cutting component 6 includes a cutting driving component 61 and a cutter wire clamping component 62. The cutting driving component 61 drives the cutter wire clamping component 62 to move along the vertical direction and the horizontal direction. The cutting driving component 61 realizes the movement of the cutter wire clamping component 62 in two directions through the connection structure of two groups of motors 611 and lead screws 612.

[0051] The cutter wire clamping component 62 includes a mounting seat 621, a connecting block 622, a fixed clamping plate 623, a movable clamping block 624, a spring, a cutter 625 and a cutter driving device 626. The cutter driving device 626 and the fixed clamping plate 623 are fixedly arranged on the mounting seat 621. In this embodiment, the fixed clamping plate 623 is connected to the mounting seat 621 through a connecting shaft 627 extending along the vertical direction. The movable clamping block 624 and the cutter 625 are arranged on the connecting block 622. The spring is connected between the movable clamping block 624 and the connecting block 622. The connecting shaft 627 is located between the cutter 625 and the movable clamping block 624. When the cutter driving device 626 drives the connecting block 622 to move, it drives the cutter 625 and the movable clamping block 624 to move. The movable clamping block 624 moves towards the fixed clamping plate 623. During the movement, the movable clamping block 624 and the fixed clamping plate 623 clamp the wire, the spring is compressed, and the cutter 625 advances to cut the wire. In this embodiment, the cutter 625 is located between the winding component 3 and the movable clamping block 624, so that after the cutter 625 cuts the wire, the movable clamping block 624 and the fixed clamping plate 623 still clamp the wire, which is convenient for the cutting driving component 62 to drive the wire to move to the winding component 3.

[0052] See Figure 6, the winding component 3 includes two rotating shaft components 7 and two wire clamping components 31. The structures of the two rotating shaft components 7 are the same, and the structures of the two wire clamping components 31 are the same. One wire clamping component is correspondingly connected to one rotating shaft component. The rotating shaft component 7 includes a rotating shaft 71, a rotating shaft rotation driving device 72, and a fixing component 73. The rotating shaft rotation driving device 72 drives the rotating shaft 71 to rotate, and the rotating shaft 71 is provided with a skeleton fixing portion 711. The fixing component 73 is used to fix the skeleton on the rotating shaft 71. The wire clamping component 31 is located on the rotating shaft 71, and a wire clamping position 310 is provided on the wire clamping component 31. The wire is clamped by the wire clamping component 31 at the wire clamping position 310.

[0053] In this embodiment, the fixing assembly 73 includes a cable nozzle 731, a second spring and a cable nozzle driving assembly. The cable nozzle driving assembly includes two cable nozzle driving devices 732, a connecting plate 733 and a driving sleeve 734. A hollow portion 735 is arranged in the driving sleeve 734. A first step is arranged on the inner side wall of the driving sleeve 734. The rotating shaft 71 is located in the cable nozzle 731. The cable nozzle 731 is arranged in the hollow portion 735. A second step is arranged on the outer side wall of the cable nozzle 731. The second spring abuts between the first step and the second step. The cable nozzle driving device 732 drives the driving sleeve 734 to move along the axial direction of the rotating shaft 71 away from the frame fixing portion 711. The driving sleeve 734 drives the cable nozzle 731 to move away from the frame fixing portion 711. The second spring drives the cable nozzle 731 to move toward the frame fixing portion 711. A driving groove 736 is provided on the outer wall of the driving sleeve 734, and the driving groove 736 is arranged along the circumference of the driving sleeve 734. A driving block 737 is provided on the side wall of the connecting plate 733 facing the driving groove 736, and the driving block 737 is arranged in the driving groove 736. Two cable nozzle driving devices 732 are respectively located on two opposite sides of the connecting plate 733, and the two cable nozzle driving devices 732 are respectively connected to the connecting plate 733. The structure of the driving sleeve 734 can realize that when the cable nozzle driving device 732 drives the driving sleeve 734 to move, the rotation of the driving sleeve 734 and the movement of the driving sleeve 734 do not interfere with each other. The cable nozzle 731 includes a plurality of elastic clamping pieces 7311, and the plurality of clamping pieces 7311 are arranged along the circumference of the rotating shaft 71. The rotating shaft 71 is located in the space surrounded by the plurality of clamping pieces of the cable nozzle 731, and the skeleton on the rotating shaft 71 is clamped by the cable nozzle 731. In this embodiment, a plurality of abutment blocks are arranged on the inner side wall of the driving sleeve 734 facing the hollow part 735, and an abutment step is arranged on the side wall of each clamping block facing the driving sleeve, and the abutment blocks are abutted and connected with the abutment steps one by one. When the skeleton is fixed in the cable mouth 731, the cable mouth driving device 732 drives the driving sleeve 734 to move through the connecting plate 733, and the abutment blocks abut against the abutment steps, driving the clamping pieces 7311 in the cable mouth 731 to disperse, and the second spring is compressed, so that the rotating shaft 71 is convex relative to the cable mouth 731. After the skeleton is placed on the rotating shaft 71, the cable mouth driving device 732 stops driving, and under the elastic force of the second spring, the driving sleeve 734 moves in the reverse direction, and the abutment blocks move away from the abutment steps, driving the clamping pieces 7311 of the cable mouth 731 to move together under the elastic force of the second spring, thereby clamping the skeleton.

[0054] In this embodiment, see Figure 7 and Figure 8, the wire clamping assembly 31 includes a first clamping block 311, a second clamping block 312 and a wire clamping drive assembly. In this embodiment, a through hole 3121 is provided on the second clamping block 312, and the drive sleeve 734 is located within the through hole 3121; the second clamping block 312 is fixedly provided near the skeleton fixing portion 711 of the drive sleeve 734. Along the vertical direction, the first clamping block 311 is arranged above the second clamping block 312, and the first clamping block 311 is hinged to the second clamping block 312, such that a hinge portion 3111 is formed on the second clamping block 312. The wire clamping drive assembly includes a mounting plate 313, four first springs 314 and two wire clamping drive devices 315. Two through holes are provided on the mounting plate 313. A rotating shaft 71 passes through one through hole 3131, and a mating structure of a first clamping block 311 and a second clamping block 312 corresponds to one rotating shaft 71. A drive block 3112 is provided on the side wall of the first clamping block 311 facing the mounting plate 313. The hinge portion 3111 is arranged between the wire clamping position 310 and the drive block 3112, and the drive block 3112 is inclined. Two parallel channels 3122 are provided within the second clamping block 312. One first spring 314 is placed within one channel 3122, and the first spring 314 is respectively connected to the first clamping block 311 and the second clamping block 312. The two wire clamping drive devices 315 are respectively connected to the mounting plate 313. The wire clamping drive device 315 drives the mounting plate 313 to move. When the mounting plate 313 abuts against the drive block 3112, the movement of the mounting plate 313 drives the first clamping block 311 to move away from the second clamping block 312, and at the same time, the first spring 314 is stretched. When the wire clamping drive device 315 stops driving, under the pulling force of the first spring 314, the first clamping block 311 moves towards the second clamping block 312 to achieve wire clamping.

[0055] A wire positioning block 3123 is convexly provided on the side wall of the second clamping block 312 facing the first clamping block 311. The wire positioning block 3123 is arranged between the skeleton fixing portion 711 and the second clamping block 312. The wire positioning block 3123 is used to position the position of the wire. After the wire is clamped by the first clamping block 311 and the second clamping block 312, it is wound around the skeleton through the wire positioning block 3123. The plane of the wire positioning block 3123 facing the wire can be close to the plane where the skeleton fixing portion 711 is located, such that the wire is flat and the effect of winding the wire on the skeleton in a stacked manner is better. In this embodiment, the side wall of the wire positioning block 3123 facing the through hole 3121 is arc-shaped, reducing the influence on the rotation of the coil within the through hole 3121.

[0057] The folding line clamping assembly 8 includes a mounting plate 81, a first clamping assembly 82, a second clamping assembly 83, and a clamping rotation driving device 84.

[0058] In this embodiment, the structures of the first clamping assembly 82 and the second clamping assembly 83 are the same. Refer to Figure 10 , the first clamping assembly 82 includes a first moving block 821, a second moving block 822, and a moving block moving driving device 823. The moving block moving driving device 823 can simultaneously drive the first moving block 821 and the second moving block 822 to move towards or away from each other. Refer to Figure 11 , a first mounting strip 8211, a connecting block 8212, a first connecting seat 8213, a first clamping block 8214, and a second clamping block 8215 are formed on the first moving block 821. The first mounting strip 8211, the connecting block 8212, the first connecting seat 8213, the first clamping block 8214, and the second clamping block 8215 are integrally formed. In this embodiment, the first clamping block 8214 and the first connecting seat 8213 are respectively fixed on the first mounting strip 8211, and the first clamping block 8214 and the first connecting seat 8213 are respectively located on two opposite side walls of the first mounting strip 8211. The second clamping block 8215 is fixedly arranged on the first mounting strip 8211 through the connecting block 8212. The first clamping block 8214 and the second clamping block 8215 are located on the same side of the first mounting strip 8211. Along the vertical direction, a moving track 8216 is provided between the second clamping block 8215 and the side wall of the first mounting strip 8211 where the first clamping block 8214 is arranged. Along the horizontal direction, an avoidance space 8217 is provided between the first mounting strip 8211 and the second clamping block 8215.

[0059] Refer to Figure 12, the second moving block 822 includes a second mounting strip 8221, a second connecting seat 8222, a third clamping block 8223, and a fourth clamping block 8224. The second mounting strip 8221, the second connecting seat 8222, the third clamping block 8223, and the fourth clamping block 8224 are integrally formed and connected. The third clamping block 8223 and the fourth clamping block 8224 are fixed on the same side wall of the second mounting strip 8221. The second connecting seat 8222 and the third clamping block 8223 are respectively located on the opposite side walls of the second mounting strip 8221. The second mounting strip 8221 is located within the moving track 8216, and the second connecting seat 8222 is located within the avoidance vacancy 8217, thereby embedding the second moving block 822 into the first moving block 821.

[0060] In this embodiment, a limiting block 8218 is provided on the side wall of the second clamping block 8215 facing the moving track 8216, and a limiting groove 8225 is provided on the side wall of the second mounting strip 8221 facing the limiting block 8218. The limiting block 8218 moves within the limiting groove 8225. A first clamping portion 824 is formed between the first clamping block 8214 and the third clamping block 8223, and a second clamping portion 825 is formed between the second clamping block 8215 and the fourth clamping block 8224. The moving block moving driving device 823 simultaneously drives the first moving block 821 and the second moving block 822 to move horizontally, so that the first clamping block 8214 and the third clamping block 8223 move towards each other, and the fourth clamping block 8224 and the second clamping block 8215 move towards each other. The first clamping portion 824 and the second clamping portion 825 are arranged collinearly along the moving direction of the third clamping block 8223. Since the second mounting strip 8221 is located within the moving track 8216, the moving track 8216 limits the movement of the second moving block 822. And in this embodiment, an extension block 8219 is provided on the side wall of the second clamping block 8215 facing away from the fourth clamping block 8224. Along the vertical direction, the extension block 8219 is arranged above the moving track 8216, and the arrangement of the extension block 8219 further limits the second mounting strip 8221 within the moving track 8216. Since the limiting block 8218 is arranged within the limiting groove 8225, when the second moving block 822 moves, the limiting block 8218 moves within the limiting groove 8225, and the length of the limiting groove 8225 along the moving direction of the third clamping block 8223 can be used to limit the moving range of the second moving block 822. In this embodiment, the feeding station 811 is arranged close to the winding assembly 3, the folding station 812 is close to the first folding assembly 42 and the second folding assembly, and the folding station 812 is located between the first folding assembly 42 and the second folding assembly.

[0061] On the first mounting bar 8211, there are a first fixing seat 826 and a second fixing seat 827. The first fixing seat 826 is located between the first clamping block 8214 and the third clamping block 8223, and the second fixing seat 827 is arranged between the second clamping block 8215 and the fourth clamping block 8224. There are first gaps 828 respectively between the fixed ends of the first fixing seat 826 and the first clamping block 8214 and the third clamping block 8223, and second gaps 829 respectively between the fixed ends of the second fixing seat 827 and the second clamping block 8215 and the fourth clamping block 8224. The first fixing seat 826 is located within the first clamping portion 824, and the second fixing seat 827 is located within the second clamping portion 825. The first fixing seat 826 and the second fixing seat 827 are respectively used for placing coils. When the two clamping blocks clamp the coils on the fixing seats, the first gaps 828 and the second gaps 829 respectively correspond to two connection feet on the coils, facilitating the folding block to enter the gaps to fold the connection feet, and the setting of the gaps can limit the folding block.

[0062] In the folding mechanism 4, since the mounting plate 81 is provided with two clamping assemblies, during folding, the clamping assembly located at the feeding station 811 clamps the coil that has completed winding after loading, and the coil clamped by the clamping assembly located at the folding station 812 undergoes the folding process steps. The coils at the two stations work simultaneously, effectively improving the working efficiency. When the clamping assembly works, the moving block moves the driving device 83 to drive the third clamping block 8223 to move towards the first clamping block 8214 and the fourth clamping block 8224 to move towards the second clamping block 8215, so that the first clamping block 8214 and the third clamping block 8223, and the second clamping block 8215 and the fourth clamping block 8224 respectively clamp the coil simultaneously, resulting in two clamping portions on one clamping assembly. Since the mounting plate 81 is provided with two clamping assemblies, there are four clamping portions on the mounting plate 81, and the coils on the four clamping portions work simultaneously, further improving the working efficiency.

[0063] The pressing block assembly 41 is arranged above the folding station 812 of the folding clamping assembly 8. Refer to Figure 13 , the pressing block assembly 41 includes two pressing blocks 411 and a pressing block driving assembly 412. The pressing block driving assembly 412 drives the two pressing blocks 411 to move towards the folding station 812 in the vertical direction, and one pressing block respectively presses the coil within one clamping portion. The feeding and conveying assembly moves the wound coil to the feeding station 811 and places the coils respectively within the clamping portions, and the pressing blocks press the coils within the clamping portions.

[0064] The first folding line component 42 and the second folding line component are respectively located on two opposite sides of the folding line station 812. The first folding line component 42 includes a first folding line driving component 422 and a first folding line block 421. The first folding line driving component 422 drives the first folding line block 421 to move towards or away from the folding line station 812. The first folding line driving component 422 includes a vertical driving component 4221 and a horizontal driving component 4222. The vertical driving component 4221 drives the first folding line block 421 to move in the vertical direction, and the horizontal driving component 4222 drives the first folding line block 421 to move in the vertical direction. In this embodiment, the vertical driving component 4221 drives the first folding line block 421 to move in the vertical direction through a cylinder, and the horizontal driving component 4222 is the same. Refer to Figure 14 , two driving pieces 4211 are arranged on the first folding line block 421, a positioning groove 4210 is arranged between the two driving pieces, and the two driving pieces 4211 respectively correspond to two connecting feet. Pushing blocks 4212 are respectively arranged on the side walls of the two driving pieces 4211 facing the folding line clamping component 8. A folding line step 4213 is formed between the protruding pushing blocks 4212 and the driving pieces 4211, and the first clamping part 824 can be located on the folding line step 4213. Since the first folding line block 421 can move in the vertical direction and the horizontal direction, the first folding line block 421 can perform two foldings. When the first folding line block 421 moves in the vertical direction, the pushing block 4212 pushes the connecting foot to extend in the vertical direction. When the first folding line block 421 moves in the horizontal direction, the coil on the first clamping part 824 gradually enters the folding line step 4213, and the connecting foot that originally extended in the vertical direction is extended towards the horizontal direction. The setting of the folding line step 4213 can also limit the displacement of the pushing block 4212 moving in the horizontal direction.

[0065] The second folding line component includes a second folding line driving component, a second folding line block 91 and a lower cutting tool component. In the vertical direction, the second folding line block 91 is arranged above the lower cutting tool component, and the folding line station 812 is located between the second folding line block 91 and the lower cutting tool component. The second folding line driving component drives the second folding line block 91 to move towards or away from the folding line station 812 in the vertical direction, and the moving direction of the second folding of the first folding line block 421 intersects with the moving direction of the second folding line block 91. The first folding line component 42 and the second folding line component are respectively located on two opposite sides of the folding line station 812 on the mounting plate 81, so as to perform foldings in different directions and complete multiple foldings.

[0066] In this embodiment, the second folding line block 91 is a cutting tool, and the second folding line driving component drives the second folding line block 91 to move towards or away from the lower cutting tool component through the connection structure of a motor and a lead screw. Refer to Figure 15, the lower cutting knife assembly includes a lower cutting knife driving assembly 93 and a lower cutting knife block 92. The lower cutting knife driving assembly 93 drives the lower cutting knife block 92 to move vertically towards or away from the second folding line block 91 through the connection structure between the motor and the lead screw. A groove 921 is provided on the side wall of the lower cutting knife block 92 facing the second folding line block 91, and a cutting edge 922 is formed on the lower cutting knife block 92. The second folding line block 91 enters the groove 921, and the cutting edge on the second folding line block 91 is arranged in cooperation with the cutting edge 922 on the lower cutting knife block 92. Since the second folding line block 91 is a cutting knife, when the second folding line block 91 and the lower cutting knife block 92 move towards each other respectively, while the second folding line block 91 drives the connecting foot to bend, it also drives the connecting foot to enter the groove 921 of the lower cutting knife block 92 at the same time. While completing the tangent, the bending is realized, and the two technological steps are combined into one, which further improves the working efficiency under the condition of a simpler structure of the second folding line assembly.

[0067] See Figure 16 , on the side wall of the second folding line block 91 facing the folding line clamping assembly 8, a first inclined surface 911 and a second inclined surface 912 are provided. The first inclined surface 911 and the second inclined surface 912 are arranged oppositely, and one inclined surface corresponds to one connecting foot of the coil for tangent cutting respectively.

[0068] On the side wall of the lower cutting knife block 92 facing the groove 921, a third inclined surface 923 and a fourth inclined surface 924 are provided. The first inclined surface 911 and the third inclined surface 923 are opposite and parallel, and the second inclined surface 912 and the fourth inclined surface 924 are opposite and parallel. The arrangement of the inclined surfaces on the second folding line block 91 and the inclined surfaces on the lower cutting knife block 92 can make the connecting foot have an inclined cutting surface while cutting the connecting foot of the coil.

[0069] The third folding line assembly 43 is arranged between the second folding line block 91 and the lower cutting knife assembly, and the third folding line assembly 43 and the second folding line assembly are located on the same side of the folding line station 812. See Figure 17 , the third folding line assembly 43 includes a third folding line block 431 and a third folding line driving assembly 432. The third folding line driving assembly 432 realizes the movement of the third folding line block 431 in the XYZ three directions through the connection structure of three groups of motors 4321 and lead screws 4322. The third folding line driving assembly 432 drives the third folding line block 431 to move towards or away from the folding line station 812. In this embodiment, a positioning groove 4311 is provided on the side wall of the third folding line block 431 facing the folding line station 812, so that two protruding blocks 4312 protruding relative to the positioning groove 4311 are formed on the second folding line block 91, and the positioning groove 4311 is arranged between the two protruding blocks 4312. Pushing blocks 4313 protrude respectively on the side walls of the two protruding blocks 4312 facing the folding line station 812, and pushing tips 4314 are respectively provided on the two pushing blocks 4313, and the side wall of one pushing block 4313 facing the other pushing block 4313 is arc-shaped.

[0070] The folding line mechanism 4 includes two positioning components 44, and the positioning components 44 are used for fine positioning of the coils that have completed folding. The structures of the two positioning components 44 are the same. The positioning component includes four positioning blocks 441, a positioning cylinder 442, and a positioning mounting base 443. The positioning ends of the four positioning blocks 441 are respectively bent, and the four positioning blocks 441 are respectively hinged to the positioning mounting base 443. The four positioning blocks 441 are arranged around the positioning portion 444, and the coil is located on the positioning portion 444. The positioning cylinder 443 drives the four positioning blocks 441 to approach or disperse. After approaching, the four positioning blocks fine-tune the position of the coil, facilitating the blanking of the coil.

[0071] The blanking component 5 includes a blanking conveying component 51 and a disk loading component 52. The blanking conveying component 51 is used to move the coil on the folding line station 812 to the positioning portion 444 within the positioning component 44, and move the coil that has completed fine-tuning to the loading tray. Refer to Figure 18 , the blanking conveying component 51 includes a moving plate 511, a plurality of suction nozzle components, and a blanking conveying driving component. The plurality of suction nozzle components are arranged on the moving plate 511. The suction nozzle component includes a suction nozzle 512 and an air pipe 513, and the suction nozzle 512 is connected to the air pipe 513. The blanking conveying driving component drives the moving plate 511 to move in the vertical and horizontal directions through the connection structure of two motors 514 and a lead screw 515. Refer to Figure 19 , the disk loading component 52 includes a moving disk 521 and a disk loading driving component 522. The tray for placing the coil is placed on the moving disk 521. The disk loading driving component 522 drives the moving disk 521 to move through the connection structure of a motor 5221 and a lead screw 5222. The moving direction of the moving disk 521 is perpendicular to the moving direction of the suction nozzle 512 on the horizontal plane.

[0072] The working process of the device is generally as follows: Place the skeleton on the vibrating bowl 111. The vibrating bowl 111 arranges the skeletons in an orderly manner on the linear track 112 through vibration. The feeding and conveying assembly moves the skeletons on the linear track 112 to the rotating shaft 71 in the winding assembly 3 to fix the skeletons. Before the first winding, manually clamp the wire at the wire clamping assembly 31 inside the wire feeding block assembly 22 first. The rotating shaft 71 starts to rotate for winding, and the clamping assembly 31 releases the wire. After the rotating shaft 71 stops rotating, the cutting assembly 6 moves and starts cutting. After the cutting is completed, the wire is still clamped on the cutting assembly 6. The wound coil moves to the discharging station 811 in the folding mechanism 4, and the cutting assembly 6 drives the wire to the clamping assembly 31. The clamping assembly 31 clamps the wire and starts to repeat the steps. In the folding mechanism 4, the coil is placed in the clamping part of the discharging station 811, and the pressing block 411 presses the coil in the clamping part; at the same time, the coil at the folding station 812 is folded. The first folding block 421 can move successively in the vertical and horizontal directions for two bends. The second folding block 91 cooperates with the lower cutting block 92 to complete the third bend while cutting the wire; the third folding assembly 43 bends the wire for the fourth time. After the folding is completed, the discharging and conveying assembly 51 moves the coil to the positioning assembly 44 to fine-tune the coil so that the coil can be placed more accurately in the placement grid of the tray. During discharging, the movement of the discharging and conveying assembly 51 cooperates with the movement of the moving tray 521 to complete the loading of the tray and realize the discharging of the coil.
