[0023] Please refer to Figures 1-5 As shown in the figure, a coil wiring docking device includes a workbench 1. A cavity chamber 2 is provided inside the workbench 1. A servo motor 3 is installed inside the bottom side of the cavity chamber 2. A first gear 4 is installed at the output end of the servo motor 3. Two guide rods 5 are symmetrically and fixedly connected between the two sides of the cavity chamber 2. Slide blocks 6 are slidably installed on the outer walls of the guide rods 5. A rack 7 is installed on the top side of the slide block 6. Connecting blocks 8 are fixedly connected to one end of the top side of the rack 7. A movable plate 9 is fixedly connected to the top side of the connecting block 8. Two chute grooves 10 are symmetrically provided inside the top side of the workbench 1. The movable plate 9 is slidably installed inside the chute grooves 10. Arc-shaped wire laying grooves 11 are provided inside the movable plates 9. Mounting ears 12 are installed on one side of the movable plates 9. A trigger rod 13 and a trigger switch 14 are respectively installed on one side of the mounting ears 12. A U-shaped frame 17 is fixedly installed on the top side of the movable plate 9. A screw rod 18 is threadedly connected inside the U-shaped frame 17. A pressing block 19 is rotatably installed at the bottom end of the screw rod 18. A handle 20 is fixedly connected to the top end of the screw rod 18. A vertical rod 21 is installed on the top side of the pressing block 19. A control panel 36 is installed on one side of the workbench 1. During operation, in practical applications, when the coil is being wired and docked, accurate position positioning cannot be achieved, which will result in inaccurate wiring and docking of the coil and affect the circuit performance. Place the coil and the lead wire to be docked in the arc-shaped wire laying grooves 11 respectively. At this time, rotate the screw rod 18 by operating the handle 20. The screw rod 18 is threadedly driven inside the U-shaped frame 17 to drive the pressing block 19 to move downward to press and fix the coil and the lead wire to prevent the coil from moving during the docking process. At this time, one end of the coil and the lead wire are respectively aligned with one end of the trigger rod 13 and the trigger switch 14. Start the servo motor 3 to drive the first gear 4 to rotate, which will drive the two racks 7 to perform relative or opposite linear motions along the guide rods 5, so that the connecting blocks 8 drive the movable plate 9 to slide inside the chute grooves 10. When the movable plate 9 moves in place, the trigger rod 13 will trigger the trigger switch 14 and transmit the signal to the control panel 36, achieving accurate positioning for the docking of the coil and realizing an automated control docking process, thereby ensuring the accuracy of the docking.

[0024] Please refer to Figures 1-4As shown in the figure, a support column 15 is fixed at the center position on the top side of the workbench 1. The top end of the support column 15 is fixedly connected with a support plate 16. The top side of the support plate 16 and the bottom arc surface of the wire laying groove 11 are on the same horizontal line. An L-shaped plate 22 is fixed at the edge of the top side of the workbench 1. A cylinder 23 is installed on the top side of the L-shaped plate 22. A welding machine 24 is installed at the acting end of the cylinder 23. A welding head 25 is installed at the output end of the welding machine 24. During operation, when wiring the coil, it is necessary to transfer the signal generated or received by the coil to other parts through docking with the lead wire. When wiring is required after docking is completed, the position where the coil is docked with the lead wire is above the support plate 16, providing a stable support plane for the coil. At this time, the control panel 36 controls the cylinder 23 to operate, and its acting end pushes the welding machine 24 to move towards the docking position, and the welding head 25 also approaches the part to be welded. When the welding head 25 reaches the designated position, the welding machine 24 is started, and welding operation is carried out through the welding head 25 to realize the docking of the coil and the lead wire. The model of the welding machine 24 is WS-200.

[0025] Please refer to Figure 1 , 2 , as shown in FIG. 5, two support rods 26 are symmetrically installed at the edge of the top side of the workbench 1. An installation ring 27 is installed on the top side of the support rod 26. An annular groove 28 is opened inside the installation ring 27. An annular slider 29 is slidably installed inside the annular groove 28. A cleaning pad 30 is installed on the inner wall of the annular slider 29. Through holes 31 with different sizes are opened inside the cleaning pad 30. A toothed ring 32 is installed on the outer wall of the annular slider 29. A side ear 33 is installed on the outer wall of the installation ring 27. A driving motor 34 is installed on one side of the side ear 33. A gear two 35 is installed at the output end of the driving motor 34, and the toothed ring 32 meshes with the gear two 35. During operation, the presence of dust and impurities may affect the contact quality of the wiring, resulting in poor contact and affecting the stability and efficiency of current transmission. Start the driving motor 34 to drive the gear two 35 to rotate. Since the toothed ring 32 meshes with the gear two 35, the annular slider 29 and the cleaning pad 30 will be driven to slide inside the annular groove 28. The through holes 31 with different sizes opened inside the cleaning pad 30 can adapt to coils and lead wires with different diameters. During the sliding process of the annular slider 29, the cleaning pad 30 will contact the coil and the lead wire, thereby cleaning the dust and impurities on their surfaces before the coil wiring docking, improving the quality and reliability of the wiring.

[0026] Working principle, before docking: Start the drive motor 34 to drive the second gear 35 to rotate. Since the toothed ring 32 meshes with the second gear 35, the annular slider 29 and the cleaning pad 30 will be driven to slide in the annular groove 28. The through holes 31 with different sizes can accommodate coils and leads with different diameters. During the sliding process of the annular slider 29, the cleaning pad 30 will contact the coil and the lead, so as to clean the dust and impurities on its surface before the coil wiring is docked, improving the quality and reliability of the wiring;

[0027] Place the coils and leads to be docked in the arc-shaped wire laying grooves 11 respectively. At this time, rotate the screw rod 18 by operating the handle 20. The screw rod 18 is in threaded transmission in the U-shaped frame 17, driving the pressing block 19 to move downward to press and fix the coils and leads, preventing the coils from moving during the docking process. At this time, one end of the coil and the lead are respectively aligned with one end of the trigger rod 13 and the trigger switch 14. Start the servo motor 3 to drive the first gear 4 to rotate, which will drive the two racks 7 to move linearly relative to or away from each other along the guide rod 5, so that the connecting block 8 drives the movable plate 9 to slide in the chute 10. When the movable plate 9 moves in place, the trigger rod 13 will trigger the trigger switch 14 and transmit the signal to the control panel 36, providing accurate positioning for the docking of the coils, realizing the automated control of the docking process, and thus ensuring the accuracy of the docking;

[0028] When wiring is required after docking, the docking position of the coil and the lead is located above the support plate 16. The coil provides a stable support plane. At this time, the control panel 36 controls the cylinder 23 to operate, and its acting end pushes the welding machine 24 to move towards the docking position, and the welding head 25 also approaches the part to be welded. When the welding head 25 reaches the specified position, the welding machine 24 is started, and welding operation is carried out through the welding head 25 to realize the welding and fixing of the coil and the lead.
