Description

Technical Field

[0001] The invention relates to the field of electronic component coil preparation equipment, and in particular to a stranded wire winding assembly and a stranding method and a stranded wire winding device. Background Art

[0002] Depending on the application scenarios of electronic components, there are different requirements for the preparation of the powered coils in the electronic components, such as the number of turns of the powered coil, whether the ends of the powered coils are covered with casings, or whether the powered coils need to be wound by twisting multiple wires. According to the different production requirements of the powered coils, the settings on the coil preparation device are also relatively different. For example, for coils that need to be threaded with casings, the coil preparation device needs to add casing conveying components, casing cutting components, and casing threading components; for coils that need to be wound by twisting multiple wires, the coil preparation device needs to add a twisting component.

[0003] In the existing twisted wire winding device, the twisted wire assembly is located above the winding assembly, the twisted wire assembly is used to twist multiple wires, and the winding assembly is used to wind the twisted wires on the frame to form a coil. In the twisted wire winding device of this structure, the twisted wire assembly and the winding assembly are independent of each other. Regardless of whether the structure of the twisted wire assembly is simple or complex, the complexity of the winding device is increased to varying degrees, making it difficult to control the manufacturing cost of the twisted wire winding device. Summary of the invention

[0004] A first object of the present invention is to provide a stranded wire winding assembly that reduces the complexity of the stranded wire winding device.

[0005] A second object of the present invention is to provide a stranded wire winding method for the stranded wire winding assembly described above.

[0006] A third object of the present invention is to provide a stranded wire winding device comprising the stranded wire winding assembly.

[0007] In order to achieve the above-mentioned first purpose, the stranded wire winding assembly provided by the present invention includes a wire nozzle crossbeam assembly and a rotating spindle assembly, the wire nozzle crossbeam assembly includes a wire nozzle crossbeam and a wire nozzle driving assembly, the wire nozzle driving assembly drives the wire nozzle crossbeam to move toward or away from the rotating spindle assembly, the wire nozzle driving assembly drives the wire nozzle crossbeam to rotate, multiple groups of wire nozzle assemblies are arranged on the wire nozzle crossbeam, the wire nozzle assembly includes at least two wire nozzles; the rotating spindle assembly includes multiple rotating spindles and a spindle driving assembly, the spindle driving assembly drives the rotating spindle to move and rotate, the rotating spindle is used to connect the skeleton, multiple pins are arranged on the skeleton, multiple wires passing through the wire nozzle along the length direction of the wire nozzle are wound on the pins, and the rotating spindle drives the skeleton to rotate.

[0008] It can be seen that multiple wires pass through different wire nozzles in the wire nozzle assembly respectively, and then are wound on the pins of the skeleton. Since the axial direction of the rotating spindle is extended in the horizontal direction, the wire nozzle driving assembly drives the wire nozzle crossbeam to move away from the rotating spindle, so that the wire between the wire nozzle and the rotating spindle tends to extend in the horizontal direction. Since the wire nozzle cannot rotate around its own length direction, when the horizontally set rotating spindle rotates, it drives multiple wires in the wire nozzle assembly to be wound together to complete the wire twisting process. Then the wire nozzle driving assembly drives the wire nozzle to move toward the rotating spindle, so that the wire between the wire nozzle and the rotating spindle tends to extend in the vertical direction. The rotating spindle drives the skeleton to rotate, driving the completed twisted wire to be wound. This type of twisted wire winding assembly has a simple structure and does not require an additional twisted wire assembly. Only a wire nozzle needs to be added to the wire nozzle crossbeam of an ordinary winding machine. The twisting and winding of the wires are completed by the rotating spindle assembly and the wire nozzle crossbeam assembly, which greatly reduces the complexity of the device.

[0009] A further solution is that the length direction of the thread nozzle is located on the extension plane, the pins are located on the pin mounting surface of the frame, and the extension plane and the pin mounting surface are not arranged perpendicularly.

[0010] It can be seen that during the wire twisting process, the extension plane and the pin mounting surface are not arranged vertically, so that when twisting the wire, the wire between the wire nozzle and the rotating spindle tends to be horizontal, which makes the twisting effect better.

[0011] A further solution is that the extension plane and the pin mounting surface are parallel to or overlap each other.

[0012] It can be seen that when the extension plane and the pin mounting surface are parallel or overlapped, the length direction of the wire nozzle is parallel to the axial direction of the rotating spindle, which makes the wire twisting effect better.

[0013] A further solution is that a wire assembly is provided on the rotating spindle, the wire assembly includes a first wire block and a second wire block, a threading position is provided between the first wire block and the second wire block, and the wire assembly and the pins on the skeleton are located on the same side of the rotating spindle.

[0014] It can be seen that the wire assembly is set on the rotating main shaft. The wire is wrapped around the skeleton pin and first passes through the threading position between the first wire block and the second wire block. The wire can be guided and the moving track of the wire can be restricted before the wire is wrapped around the pin, so as to better control the moving direction of the wire.

[0015] A further solution is that a plurality of wire stripping blocks are arranged on the nozzle crossbeam, the wire stripping blocks include wire shifting blocks, and the length direction of the wire shifting blocks is arranged parallel to the axial direction of the rotating spindle.

[0016] It can be seen that after the winding is completed, when the skeleton is separated from the rotating main shaft, the wire between the first wire block and the second wire block is removed from the threading position through the wire removing block. Since the length direction of the wire removing block is arranged parallel to the axial direction of the rotating main shaft, when the wire removing block moves to the bottom of the wire, the wire removing block moves to drive the wire to separate from the threading position, thereby realizing the unloading of the coil.

[0017] A further solution is that the stranded wire winding assembly includes a plurality of wire clamping assemblies, a rotating spindle is arranged between two wire clamping assemblies, the wire clamping assembly includes a first clamping block, a second clamping block and a clamping block driving device, and the clamping block driving device drives the first clamping block to move toward or away from the second clamping block.

[0018] It can be seen that the wire clamping assembly is used to clamp the wire ends of the wires, so that the wires can be wrapped around the pins more securely.

[0019] A further solution is that a wire clamping position is provided between the first clamping block and the second clamping block, a wire pushing block is provided on the side wall of the first clamping block facing the second clamping block, a wire pushing driving device is provided on the first clamping block, and the wire pushing driving device drives the wire pushing block to move in the wire clamping position.

[0020] It can be seen that the wire pushing drive device drives the wire pushing block to move in the wire clamping position, withdraws the wire head in the wire clamping position, and facilitates the unloading of the coil.

[0021] To achieve the second objective, the stranded wire winding method provided by the present invention is applied to the stranded wire winding assembly as described above, and the stranded wire winding method comprises the following steps:

[0022] S1, multiple wires pass through the nozzles in the nozzle assembly respectively;

[0023] S2, the nozzle drives the wire to wind around the pins of the skeleton;

[0024] S3, the nozzle driving assembly drives the nozzle crossbeam to move away from the rotating spindle along the axial direction of the rotating spindle;

[0025] S4, the spindle drive assembly drives the rotating spindle to rotate and start twisting the wire;

[0026] S3. After the wire twisting is completed, the wire nozzle driving assembly drives the wire nozzle crossbeam to move along the axial direction of the rotating spindle toward the rotating spindle to start winding.

[0027] It can be seen from the above scheme that the wire passes through the wire nozzle, and the wire nozzle driving assembly drives the wire nozzle to move and rotate in multiple directions, so that the wire nozzle can drive the wire to be wound around the pins of the skeleton. When the wire nozzle driving assembly drives the wire nozzle to move away from the rotating spindle, the length of the wire between the wire nozzle and the rotating spindle is increased, so that there is enough space between the wire nozzle and the rotating spindle for twisting the wire, and the wire between the wire nozzle and the rotating spindle tends to extend in a horizontal direction. When the rotating spindle set in the horizontal direction rotates, the wire between the pins and the wire nozzle can be driven to twist the wire; after the twisting is completed, the wire nozzle driving assembly drives the wire nozzle to move above the rotating spindle, and the length direction of the wire nozzle is perpendicular to the axial direction of the rotating spindle, and the rotating spindle starts to rotate for winding.

[0028] A further solution is that in step S3, while the nozzle is moving, the nozzle driving assembly drives the nozzle beam to flip, and the length direction of the nozzle is parallel to the axial direction of the rotating spindle.

[0029] To achieve the third objective mentioned above, the stranded wire winding device provided by the present invention includes the stranded wire winding assembly as mentioned above. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The stranded wire winding device of the present invention is used for processing coils in energized components, including coils for transformers. The stranded wire winding device transfers a single skeleton to a feeding assembly through a pushing assembly, and then transfers it to the stranded wire winding device through the feeding assembly. During the skeleton transportation process, the feeding assembly gradually takes materials from a single skeleton, effectively improving the accuracy of taking materials and reducing the occurrence of empty workstations in the stranded wire winding assembly. In addition, the pushing assembly and the stranded wire winding assembly are used to transfer materials through the feeding assembly, thereby improving the degree of automation.

[0047] See also Figure 1 The stranded wire winding device comprises a vibration plate 1, a mounting platform 2, a material pushing assembly 3, a material feeding assembly 4, a material placement block 12, an S-shaped wire pulling assembly 6 and a stranded wire winding assembly 7. The vibration plate 1, the material pushing assembly 3, the material feeding assembly 4, the material placement block 12, the S-shaped wire pulling assembly 6 and the stranded wire winding assembly 7 are arranged on the mounting platform 2. The material pushing assembly 3 and the material placement block 12 are arranged between the material feeding assembly 4 and the stranded wire winding assembly 7, and the S-shaped wire pulling assembly 6 is arranged above the stranded wire winding assembly 7.

[0048] See also Figure 2 and Figure 3The pushing assembly 3 includes a waiting assembly 31 and a pushing assembly 32. The waiting assembly 31 includes a waiting track 311 and a mounting frame 310. The waiting track 311 and the pushing assembly 32 are arranged on the mounting frame 310, and the vibration plate 1 is connected to the waiting track 311. In this embodiment, the vibration plate 1 arranges the skeleton in the vibration plate 1 on the discharge track of the vibration plate 1 by vibration, and the discharge track 11 of the vibration plate 1 is connected to the waiting track 311. The skeleton on the discharge track 11 of the vibration plate 1 moves to the waiting track 311 through the vibration of the vibration plate 1. Under the vibration of the vibration plate 1, the skeleton on the discharge track 11 of the vibration plate 1 moves to the waiting track 311, and pushes the skeleton on the waiting track 311 to the pushing assembly 32.

[0049] In this embodiment, a fixing groove 312 is provided on the waiting track 311, and the length extension direction of the fixing groove 312 is the same as the extension direction of the waiting track 311. The skeleton on the discharging track 11 of the vibration plate 1 moves into the fixing groove 312, and the fixing groove 312 can limit the skeleton on the waiting track 311, so that the skeleton on the waiting track 311 can move along the extension direction of the waiting track 311. The waiting assembly 31 includes a cover plate 313, and the cover plate 313 includes a mounting plate 3130, a connecting plate 3131 and a limiting plate 3132. The mounting plate 3130 is installed on the outer wall of the waiting track 311, and the connecting plate 3131 is connected between the mounting plate 3130 and the limiting plate 3132. The limiting plate 3132 is arranged above the fixing groove 312. The limiting plate 3132 positions the skeleton in the fixing groove 312 to prevent the skeleton from falling off the waiting track 311.

[0050] The material waiting assembly 31 includes a latch assembly, which includes a mounting block 314, a latch 315 and a latch driving device 316. The mounting block 314 is arranged on the mounting block, and the latch driving device 316 is arranged on the mounting block 314. The latch driving device 316 drives the latch 315 to move toward the material waiting track 311, and the moving direction of the latch 315 is perpendicular to the extension direction of the material waiting track 311. When the skeleton on the material waiting track 311 has moved to the pushing assembly 32, the latch driving device 316 drives the latch 315 to move toward the material waiting track 311 to prevent the skeleton on the material waiting track 311 from detaching from the material waiting track 311 after moving. In this embodiment, the latch 315 passes through the side wall of the fixing groove 312.

[0051] An optical fiber sensor 317 is provided between the latch 315 and the push assembly 3, and the optical fiber sensor 317 is provided on the mounting block 314, and the optical fiber sensor 317 is provided between the latch 315 and the push assembly 32. The optical fiber sensor 317 is used to detect whether a skeleton moves onto the push assembly 3, so as to further improve the accuracy of skeleton conveying.

[0052] The push assembly 32 includes a discharge block 321 and a push drive assembly 33. The discharge block is located in the extension direction of the waiting track 311. The push drive assembly 33 drives the discharge block 321 to move toward or away from the waiting track 311. In this embodiment, a groove 322 is provided on the discharge block 321, and the fixed groove 312 is connected with the groove 322 along the length extension direction of the fixed groove 312. The skeleton on the discharge track 11 of the vibration plate 1 moves to the waiting track 311 through vibration, and the skeleton on the waiting track 311 is squeezed into the groove 322 of the discharge block 321. The discharge block 321 is used to place a single skeleton.

[0053] In this embodiment, a pressing block 323 and a pressing block driving device 324 are provided above the material discharging block 321. The pressing block driving device 324 drives the pressing block 323 to move toward the material discharging block 321 to press the skeleton on the material discharging block 321. When the pushing assembly 32 is feeding, the pressing block 323 presses the skeleton to prevent the skeleton on the material discharging block 321 from shifting or falling, thereby improving the accuracy of skeleton transportation.

[0054] The push drive assembly 33 includes a first direction drive assembly 34 and a second direction drive assembly 35. The first direction drive assembly 34 drives the material discharging block 321 to move along the first direction X. The second direction drive assembly 35 drives the material discharging block 321 and the first direction drive assembly 34 to move along the second direction Y. The first direction X is perpendicular to the extension direction of the waiting material track 311 in the horizontal plane, and the first direction X and the second direction Y are perpendicular in the vertical plane. It can be seen that the multi-directional movability of the material discharging block 321 cooperates with the movability of the material discharging block 321, which facilitates the accurate completion of the transfer of materials between the push assembly 3 and the feeding assembly 4.

[0055] In this embodiment, the first direction driving assembly 34 includes a moving block 341, a first guide rail 342 and a first direction driving device 343. The first guide rail 342 and the first direction driving device 343 are arranged on the moving block 341. The first guide rail 342 extends along the first direction X. The material discharging block 321 is connected with the first guide rail 342. The first direction driving device 343 drives the material discharging block 321 to move along the first direction X. The second direction driving assembly 35 includes a second guide rail 351 and a second direction driving device 352. The second guide rail 351 is arranged on the mounting frame 310. The second guide rail 351 extends along the second direction Y. The moving block 341 is connected with the second guide rail 351. The second direction driving device 352 drives the moving block 341 to move along the second direction Y.

[0056] The push assembly 32 includes a buffer assembly 36, and the buffer assembly 36 includes a buffer 361 and a limit block 362. The limit block 362 is arranged on the mounting frame 310, and the buffer 361 is arranged on the moving block 341. The buffer 361 moves toward or away from the limit block 362 along the second direction Y. When the material discharging block 321 and the first direction driving assembly 34 move toward the second direction Y, the buffer 361 is also driven to move along the second direction Y. When the buffer 361 contacts the limit block 362, the material discharging block 321 gradually stops moving. The buffer 361 and the limit block 362 limit the moving length of the material discharging block 321 in the second direction Y.

[0057] See also Figure 4 The feeding assembly 4 includes a feeding block 41 and a feeding drive assembly 42. A plurality of fixed shafts 43 are provided on the feeding block 41. The feeding drive assembly 42 drives the feeding block 41 to move. In the present embodiment, the feeding drive assembly 42 includes a first feeding drive assembly 44 and a second feeding drive assembly 45. The first feeding drive assembly 44 includes a moving block 441, a rotating motor 442, two rotating wheels 443 and a transmission belt 444. The two rotating motors 442 are respectively connected to the two rotating wheels 443 in a one-to-one correspondence. The transmission belts 444 are respectively connected to the two rotating wheels 443. The moving block 441 is connected to the transmission belt 444. The transmission belt 444 drives the moving block 441 to move between the pushing assembly 3 and the stranded wire winding assembly 7. The second feeding drive assembly 44 and the feeding block 41 are respectively arranged on the moving block 441, and the second feeding drive assembly 45 includes two driving cylinders 451. The second feeding drive assembly 45 drives the feeding block 41 to move toward or away from the discharge block 321, or the second feeding drive assembly 45 drives the feeding block 41 to move toward or away from the stranded wire winding assembly 7. Four fixed shafts 43 are arranged on the side wall of the feeding block 41 away from the second feeding drive assembly 45, and the feeding drive assembly 42 drives the four fixed shafts 43 to grab the skeletons on the discharge block 321 one by one, so as to improve the accuracy of the feeding assembly 4 grabbing the skeletons.

[0058] During the operation of the pushing assembly 3, when the vibration plate 1 drives multiple skeleton pieces to be arranged on the waiting track 311 and drives a single skeleton to enter the discharge block 321, the latch driving device 316 drives the latch 315 to penetrate the side wall of the fixing groove 312 to prevent another skeleton from entering the discharge block 321. The pressing block 323 above the discharge block 321 presses the skeleton, the pushing drive assembly 32 drives the discharge block 321 to move toward the feeding assembly 4, the feeding drive assembly 42 in the feeding assembly 4 drives the feeding block 41 to move toward the discharge block 321, and the fixed shaft 43 on the feeding block 41 grabs the skeleton on the discharge block 321 one by one, and then the feeding drive assembly 42 drives the feeding block 41 toward the stranded wire winding assembly 7 to transfer the skeleton to the rotating spindle assembly 7; in the above process, the discharge block 321 only transports a single skeleton at a time, and the multiple fixed shafts 43 on the feeding block 41 take the material one by one, so as to better ensure that each fixed shaft 43 on the feeding can take the material smoothly, avoid empty workstations when the stranded wire is wound, and the skeleton is transported from the pushing assembly 3 to the stranded wire winding assembly 7 through the feeding block 41 to improve the degree of automation.

[0059] See also Figure 5 The S-shaped wire pulling assembly 6 is arranged above the twisted wire winding assembly 7. The S-shaped wire pulling assembly 6 is used to adjust the tightness of the wire to be twisted and wound to avoid the wire being too loose after the twisting is completed, which affects the twisted wire winding effect.

[0060] See also Figure 6 The S-shaped wire pulling assembly 6 includes a wire pulling mounting frame 60, a first wire passing rod assembly 61 and a second wire passing rod assembly 62. The first wire passing rod assembly 61 and the second wire passing rod assembly 62 are arranged on the wire pulling mounting frame 60. A mounting end surface 601 is arranged at the bottom of the wire pulling mounting frame 60, and the mounting end surface 601 is arranged in a horizontal direction.

[0061] In this embodiment, the first wire-crossing rod assembly 61 includes a first wire-crossing rod 611 and a first movable assembly 612, the first movable assembly 612 drives the first wire-crossing rod 611 to move in a first plane, and the second wire-crossing rod assembly 62 includes a second wire-crossing rod 621 and a second movable assembly 622, the second movable assembly drives the second wire-crossing rod 621 to move in a second plane, the first plane and the second plane are parallel, and the moving direction of the first wire-crossing rod 611 is opposite to the moving direction of the second wire-crossing rod 621; based on the mounting end face 601, the setting height of the first wire-crossing rod 611 is greater than the setting height of the second wire-crossing rod 621. Since the second wire rod 621 is on the second plane outside the first plane, there is a height difference between the first wire rod 611 and the second wire rod 621. When the wire passes through the first wire rod 611 and the second wire rod 621, the wire can bypass the first wire rod 611 and the second wire rod 621 in an S shape. When the tension of the wire needs to be increased, the first moving component 612 drives the first wire rod 611 to move away from the second wire rod 621. The width between the first wire rod 611 and the second wire rod 621 is The wire tension becomes larger, so that the wire is stretched and the wire tension becomes larger. When the wire tension needs to be reduced, the first wire-passing rod 611 moves toward the second wire-passing rod 621, and the width between the first wire-passing rod 611 and the second wire-passing rod 621 becomes smaller, the wire stretching force is reduced, and the wire tension becomes smaller. The wire tension is adjusted by adjusting the width between the first wire-passing rod 611 and the second wire-passing rod 621, so that the wire tension can be adjusted more flexibly, thereby avoiding the situation where the wire tension is too small during winding and the twisting effect is poor.

[0062] In the above-mentioned embodiment of the S-shaped wire pulling assembly, the first wire rod 611 and the second wire rod 621 can be movable. As another embodiment, the second wire rod 621 can be fixed, and the first moving assembly 612 drives the first wire rod 611 to move toward or away from the second wire rod 621 to adjust the distance between the first wire rod 611 and the second wire rod 621, thereby adjusting the wire tension.

The first wire rod 611 and the second wire rod 621 have a high height based on the installation end surface 601 of the wire pulling installation frame 60, and the transmission belt 615 is respectively connected to the two rotating connecting rods 614 to form two transmission belt segments with a height difference, the first wire rod 611 is connected to one of its transmission belt segments, and the second wire rod 621 is connected to the other transmission belt segment. Through this connection mode, the first wire rod 611 and the second wire rod 621 are respectively driven to move, simplifying the driving structure.

The guide block assemblies 63 include three guide blocks 631. Guide grooves are arranged on the guide blocks 631. A single wire corresponds to a guide groove in a single guide block 631 to prevent multiple wires from being entangled before twisting, thereby affecting the twisting effect.

The wire nozzle driving assembly 82 drives the wire nozzle beam 81 to rotate. Multiple groups of wire nozzle assemblies 83 are arranged on the wire nozzle beam 81. The wire nozzle assembly 83 includes at least two wire nozzles 831. In this embodiment, the wire nozzle assembly 83 includes three wire nozzles 831. The wire nozzle 831 is in the shape of a long tube. The multiple wire nozzles 831 are arranged in parallel. The wire passes through the wire nozzle 831 after passing through the S-shaped wire pulling assembly 6.

[0069] See also Fig. 9 and Fig.10 The rotating spindle assembly 9 includes a plurality of rotating spindles 91 and a spindle driving assembly 92. The spindle driving assembly 92 drives the rotating spindles 91 to move and rotate. The rotating spindles 91 are used to connect the skeleton. The number of the rotating spindles 91, the number of the nozzle assemblies 83, the number of the first guide assemblies 84, and the number of the second guide assemblies 85 are equal. Fig.11 The frame 10 includes a central groove 101 and a pin mounting surface 102. The fixed shaft 43 and the rotating main shaft 91 are inserted into the central groove 101 to grab the frame. Two rows of parallel pins 103 are arranged on the pin mounting surface 102. A plurality of wires passing through the wire nozzle 831 along the length direction of the wire nozzle 831 are wound around the pins 103. The rotating main shaft 91 drives the frame 10 to rotate.

[0070] The wires pass through different wire nozzles 831 in the wire nozzle assembly 83 respectively, and then are wound on the pins of the skeleton. Since the axial direction of the rotating spindle 91 is extended in the horizontal direction, the wire nozzle driving assembly 82 drives the wire nozzle crossbeam 81 to move away from the rotating spindle 91, so that the wire between the wire nozzle 831 and the rotating spindle 91 tends to extend in the horizontal direction. Since the wire nozzle 831 cannot rotate around its own length direction, when the horizontally set rotating spindle 91 rotates, it drives the multiple wires in the wire nozzle assembly 83 to be wound together to complete the twisting process, and then the wire nozzle driving assembly Component 82 drives the wire nozzle 831 to move toward the rotating main shaft 91, so that the wire between the wire nozzle 831 and the rotating main shaft 91 tends to extend in the vertical direction. The rotating main shaft 91 drives the skeleton to rotate, driving the wire that has been twisted to be wound. This type of twisted wire winding assembly 7 has a simple structure and does not require an additional twisting assembly. It only requires adding a wire nozzle 831 to the wire nozzle crossbeam 81 of an ordinary winding machine to control the number of single wires required to twist into a strand of wire. The twisting and winding of the wire are completed by the rotating main shaft assembly 9 and the wire nozzle crossbeam assembly 8, which greatly reduces the complexity of the device.

[0071] In this embodiment, before twisting the wire, the wire nozzle driving assembly 82 drives the wire nozzle cross beam 81 to move in the horizontal direction away from the rotating spindle assembly 9. Before the wire nozzle 831 moves, the length direction of the wire nozzle 831 is perpendicular to the pin mounting surface 102. Since the axial direction of the rotating spindle 91 extends in the horizontal direction, the length direction of the wire nozzle 831 is perpendicular to the axial direction of the rotating spindle 91. The wire nozzle driving assembly 82 drives the wire nozzle cross beam 81 to move in the horizontal direction away from the rotating spindle assembly 9, stretching the length of the wire between the wire nozzle 831 and the rotating spindle 91, so that there is enough space between the wire nozzle 831 and the rotating spindle 91 for twisting the wire. The wire nozzle driving assembly 82 drives the wire nozzle cross beam 81 to rotate, driving the length direction of the wire nozzle 831 to extend in the horizontal direction, so that the extension plane is parallel to the pin mounting surface 102, or the wire nozzle driving assembly 82 drives the wire nozzle cross beam 81 to move downward, so that the extension plane overlaps with the pin mounting surface 102, so that the wire between the wire nozzle 831 and the rotating spindle 91 is parallel in the horizontal direction. When the wire between the wire nozzle 831 and the rotating spindle 91 is arranged horizontally, the rotating spindle driving assembly 92 drives the rotating spindle 91 to rotate, driving the skeleton 10 to rotate, thereby driving the wire wrapped around the pins 103 of the skeleton 10 to be twisted; the overlap of the extension plane and the pin mounting surface 102 makes the twisting effect better.

The rotation drive assembly 84 includes a rotating motor 841 and a detection assembly. The rotating motor 841 drives the nozzle crossbeam 81 to rotate. The detection assembly includes a rotating piece 842 and two photoelectric sensors 843. The rotating piece 842 is connected to the nozzle crossbeam 81. The rotation of the nozzle crossbeam 81 drives the rotating piece 842 to pass through the two photoelectric sensors 843 respectively.

[0073] The moving driving assembly 85 drives the beam mounting frame 83 to move in the vertical direction and the horizontal direction.

[0074] In this embodiment, a plurality of guide blocks 86 and a plurality of cutters 87 are also provided on the nozzle cross beam 81. In the vertical direction, one guide block 86 is correspondingly provided above one nozzle assembly 83. A guide groove 861 is provided in the guide block 861. The wire extends from the S-shaped wire drawing assembly 6 to the nozzle cross beam assembly 8, first passes through the guide groove 861 in the guide block 861, then passes through the nozzle 831, and extends to the rotating spindle 91. The cutter 87 is used to cut the wire after winding.

[0075] The rotating spindle assembly 9 includes a mounting crossbeam 93, and a plurality of rotating spindles 91 are arranged on the mounting crossbeam 93. The spindle driving assembly 92 includes a spindle rotating driving assembly 94 and a spindle moving assembly 95. The spindle moving assembly 95 drives the mounting crossbeam 93 to extend in the horizontal direction through the cooperation connection between the motor 951 and the screw rod 952. The spindle rotating driving assembly 94 drives the plurality of rotating spindles 91 to rotate synchronously through the rotating motor 941 and the transmission belt 942.

[0076] The rotating spindle assembly 9 includes a limiting assembly 95, which includes a limiting driving cylinder 951, a rotating rod 952 and a plurality of limiting rods 953. The number of limiting rods 952 is the same as the number of rotating spindles 91. Each rotating spindle 91 passes through the mounting crossbeam 93. A plurality of limiting blocks 96 are provided along the circumferential protrusion of the rotating spindle 91 at one end of the rotating spindle 91, and a limiting groove 961 is provided between every two adjacent limiting blocks 96. The driving rod of the limiting driving cylinder 951 is located in the middle of the rotating rod 952 and is hinged to the rotating rod 952, so that the limiting driving cylinder 951 drives the rotating rod 952 to rotate, driving the limiting rod 952 to enter the limiting groove 961 accordingly, so as to limit the rotating spindle 91 and prevent the rotating spindle 91 from rotating in a non-rotatable state.

[0077] In this embodiment, a plurality of limit blocks 97 are provided on the mounting crossbeam 93. In the vertical direction, one limit block 97 is correspondingly provided above one rotating main shaft 91. A limit slot 971 is provided on the limit block 97 in the vertical direction. The limit slot 971 is provided with an opening 972 in the horizontal direction, and the opening 972 is connected to the limit slot 971. The wire passes through the nozzle 831 and then through the limit slot 971. The setting of the opening 972 of the limit slot 971 can more conveniently set multiple wires in one nozzle assembly 83 in the limit slot 971.

[0078] See also Fig.11 and Fig.12 The rotating main shaft 91 is provided with a through slot 911 and two grab blocks 912, and a gap 913 is provided between the two grab blocks 912, and the gap 913 is connected to the through slot 911. The radial width of the grabbing automatic ends of the two grab blocks 912 gradually decreases along the axial direction of the rotating main shaft 91, so that the grab blocks 912 first enter the central slot 101 of the skeleton through the grabbing free ends with smaller widths, the two grab blocks 912 are squeezed, and the gap 913 becomes smaller, so that the two grab blocks 912 penetrate the central slot 101 of the skeleton 10 and firmly grasp the skeleton 10.

[0079] In this embodiment, a wire assembly 98 is also provided on the rotating spindle 91, and the wire assembly 98 includes a first wire block 981 and a second wire block 982, and a threading position 983 is provided between the first wire block 981 and the second wire block 982. The wire assembly 98 and the pins 103 on the skeleton 10 are located on the same side of the rotating spindle 91. Before the wire is wound around the pins 103 on the skeleton 10, it first passes through the threading position 983 between the first wire block 981 and the second wire block 982, which can guide the wire and limit the moving track of the wire before the wire is wound around the pins 103, so as to control the moving direction of the wire well. A plurality of de-threading blocks 88 are provided on the nozzle crossbeam 81, and the de-threading blocks 88 include a wire dialing block 881, and the wire dialing block 881 is arranged parallel to the axial direction of the rotating spindle 91 along the length direction of the wire dialing block 881. After winding is completed, when the skeleton 10 is separated from the rotating main shaft 91, the wire between the first wire block 981 and the second wire block 982 is removed from the threading position 983 through the wire removal block 88. Since the wire removal block 881 is arranged parallel to the axial direction of the rotating main shaft 91 along the length direction of the wire removal block 881, when the wire removal block 881 moves to the bottom of the wire, the wire removal block 881 moves to drive the wire to be separated from the threading position, thereby realizing the unloading of the coil. The structure of the fixed shaft 43 is basically the same as that of the rotating main shaft 91, except that the wire assembly 98 is arranged on the rotating main shaft 91.

[0080] See also Fig.13 and Fig.14The stranded wire winding assembly 7 includes a plurality of wire clamping assemblies 5 and a wire clamping drive assembly 50. A rotating main shaft 91 is arranged between the two wire clamping assemblies 5. The wire clamping assembly 5 includes a first clamping block 51, a second clamping block 52 and a clamping block drive device 53. The clamping block drive device 53 drives the first clamping block 51 to move toward or away from the second clamping block 52. The wire clamping assembly 5 is used to clamp the wire end of the wire material so that the wire material can be more firmly wound on the stitch 103. In this embodiment, the first clamping block 51 is provided with a wire clamping end 511, a hinged portion and a connecting end. The hinged portion is arranged between the wire clamping end and the connecting end. The hinged portion is hinged to the second wire clamping block. The wire clamping drive device 53 is connected to the connecting end. The wire clamping drive device 53 drives the wire clamping end 511 of the first wire clamping block 51 to move toward or away from the second wire clamping block 52. The wire clamping driving device 53 drives the connecting end of the first clamping block 51 to move back and forth. Since the hinged portion of the first clamping block 51 is hinged to the second clamping block 52, the wire clamping end 511 of the first clamping block 51 moves toward or away from the second clamping block 52, thereby clamping the wire.

[0081] A wire clamping position 54 is provided between the first clamping block 51 and the second clamping block 52, a wire pushing block 55 is provided on the side wall of the first clamping block 51 facing the second clamping block 52, the wire pushing block 54 is located between the wire clamping end 511 and the hinged end, and a wire pushing driving device 56 is provided on the first clamping block 51, and the wire pushing driving device 56 drives the wire pushing blocks 55 on the first clamping block 51 to move in the wire clamping position 54 through the connecting block 57.

[0082] A plurality of wire clamping assemblies 5 are arranged on the mounting block 501 , and the wire clamping driving assembly 50 drives the mounting block 501 to rotate and move in the vertical and horizontal directions.

[0083] The stranded wire winding method of the present invention is applied to the stranded wire winding assembly 7 as described above, and the stranded wire winding method comprises the following steps:

[0084] S1, the wires pass through the nozzles in the nozzle assembly respectively;

[0085] S2, the nozzle driving assembly drives the nozzle to move, driving the nozzle to drive the wire to wind around the pins of the skeleton;

[0086] S3, the nozzle driving assembly drives the nozzle crossbeam to move away from the rotating spindle along the axial direction of the rotating spindle. While the nozzle moves, the nozzle driving assembly drives the nozzle crossbeam to flip, and the length direction of the nozzle is parallel to the axial direction of the rotating spindle;

[0087] S4, the spindle drive assembly drives the rotating spindle to rotate and start twisting the wire;

[0088] S3. After the wire twisting is completed, the wire nozzle driving assembly drives the wire nozzle crossbeam to move along the axial direction of the rotating spindle toward the rotating spindle, and raises the height of the wire nozzle to start winding.

[0089] The wire passes through the wire nozzle 831, and the wire nozzle driving component 82 drives the wire nozzle 831 to move and rotate in multiple directions, so that the wire nozzle 831 can drive the wire to be wound around the pins of the skeleton. When the wire nozzle driving component 82 drives the wire nozzle 831 to move away from the rotating spindle 91, the length of the wire between the wire nozzle 831 and the rotating spindle 91 is increased, so that there is enough space between the wire nozzle 831 and the rotating spindle 91 for twisting the wire, and the wire between the wire nozzle 831 and the rotating spindle 91 tends to extend in a horizontal direction. When the rotating spindle 91 set in the horizontal direction rotates, the wire between the pins and the wire nozzle 831 can be driven to twist the wire; after the twisting is completed, the wire nozzle driving component 82 drives the wire nozzle 831 to move above the rotating spindle 91, and the length direction of the wire nozzle 831 is perpendicular to the axial direction of the rotating spindle 91, and the rotating spindle 91 starts to rotate for winding. This method of winding twisted wire is simple and does not require additional twisting components. It only requires adding a wire nozzle 831 to the wire nozzle crossbeam 81 of an ordinary winding machine. The twisting and winding of the wire are completed by rotating the main shaft assembly 9 and the wire nozzle crossbeam assembly 8, which greatly reduces the complexity of the device.

[0090] A material placement block 12 is provided between the feeding assembly 4 and the stranded wire winding assembly 7, see Fig.15 The material placement block 12 is provided with a plurality of feed troughs 121 and a plurality of feed troughs 122, and a feed trough 122 is provided between every two adjacent feed troughs 121. The feed troughs 121 and the feed troughs 122 are cross-arranged on the material placement block 12, so that the rotating spindle 91 does not need to move too much displacement when taking and feeding materials.

[0091] A material unloading assembly is provided between the material placement block 12 and the feeding assembly 4, and the material unloading assembly includes a material unloading slider 13 and a transmission belt unloading assembly 14. A material unloading slope 131 is provided on the material unloading slider 13, and a plurality of spacers 133 are provided on the material unloading slope 131, and a chute 134 is formed between two adjacent spacers 133. The transmission belt unloading assembly 14 is provided between the feeding assembly 4 and the material unloading slider 13, and the transmission belt unloading assembly 14 includes a transmission belt driving device 141, a transmission belt 142 and an inclined plate 143. The transmission belt driving device 141 drives the transmission belt 142 to move, and the inclined plate 143 is provided at one end of the transmission belt 142, and a collection box may be placed below the inclined plate 143. The bottom surface of the discharge chute 122 is also an inclined surface. The coil slides in the discharge chute 122 to the discharge slider 13, slides to the conveyor belt 142 through the slide groove 134 formed by the partition 133 on the inclined surface 131 of the discharge slider 13, and falls into the storage box through the transmission belt 142 and the inclined plate 143.

[0092] In the automatic feeding strand winding assembly 7, a single skeleton is transferred to the feeding assembly 4 each time through the push assembly 32. After the four fixed shafts 43 in the feeding assembly 4 have all grabbed the skeleton, it moves to the material placement block 12. In this embodiment, there are 12 feeding troughs 121 on the material placement block 12. After the 12 feeding troughs 121 are all loaded with skeletons, the main shaft assembly 9 is rotated to take the material. The feeding trough 121 is provided with a narrowed opening 1211 on the side facing the feeding assembly 4. The fixed shaft 43 places the skeleton in the feeding trough 121 from the opening at the top of the feeding trough 121, and exits the feeding trough 121 through the narrowed opening 1211, thereby completing the feeding of the fixed shaft 43. After the rotating main shaft 91 takes the material, the strand winding begins. When the rotating spindle 91 unloads the coil, since a narrowed opening 1221 is also provided on the side of the unloading trough 122 facing the rotating spindle assembly 9, the rotating spindle 91 enters the unloading trough 122 through the opening at the top of the unloading trough 122 and exits the unloading trough 122 through the narrowed opening 1221 to complete the unloading.
