[0055] like Figure 13 As shown, the inward winding device of the inlet and outlet lines performs a winding operation on a certain copper wire, as detailed below:

[0056] Preliminary preparations

[0057] Install and fix the upper and lower molds 1a in the corresponding positions of the automated winding equipment to ensure a stable installation. The upper mold 1 and the lower mold 2 have been assembled. The upper mold assembly consists of the upper mold fixing seat 3, the upper mold pad 4 and the upper mold cover 5. The lower mold assembly consists of the lower mold cover 10, the lower mold pad 9, the lower mold fixing seat 8 and the mold core 12. The mold core 12 is located at the center of the top of the lower mold cover 10.

[0058] Incoming line process

[0059] The copper wire is introduced from outside the equipment and first passes through the wire guide mechanism 3a. The copper wire passes through the wire guide shaft 42 in the vertical wire limiting assembly 40. The wire guide shaft 42 is supported and fixed by the support frame 43. The wire guide shaft 42 controls the copper wire to be at the same height as the guide wheel mechanism 2a. At the same time, the copper wire passes through the wire guide nozzle 44 in the horizontal limiting assembly 41. The wire guide nozzle 44 is supported by the support plate 45. The wire guide nozzle 44 restricts the horizontal movement of the copper wire and ensures that it enters the guide wheel mechanism 2a vertically.

[0060] In the guide wheel mechanism 2a, the guide wheel component 46 and the wire clamp component 47 work together. The wire clamp component 47 clamps the copper wire, and the guide wheel component 46 controls the wire and the angle at which the copper wire enters the mold. Through the up-and-down and back-and-forth movement of the guide wheel component 46, the copper wire slides into the upper mold groove during the bending process, preparing for subsequent winding.

[0061] Winding process

[0062] Once the copper wire reaches the appropriate position, the mold core 12 is pushed up, and the copper wire begins to wind around the mold core 12. At this time, the wire inlet clamping connecting block 31 in the lower mold clamping mechanism 11 is fixed to the outside of the lower mold assembly. The lower end of the wire inlet clamping connecting block 31 is fixed to the side of the lower mold pad 9 by bolts. The wire inlet clamping block 33 and the wire inlet clamping spring 34 in the wire inlet clamping component 32 cooperate to clamp and fix the copper wire to the side of the lower mold, ensuring the stability of the copper wire position during the winding process.

[0063] During the winding process, if bending of the copper wire is required, the upper die bending mechanism 7 comes into play. The bending pin stop 18 is located on the outside of the upper die assembly, and the bending pin assembly 19 is slidably disposed in the bending pin groove 102 within the bending pin stop 18. The bending pin assembly 19 includes a bending pin seat 22 and a bending pin 21, with the bending pin 21 slidably disposed within the bending pin seat 22. The limiting and pushing component 20 includes a limiting block 24, a limiting spring 26, and a pushing block 23. The bending pin stop 18 has a limiting groove 103 and a pushing groove 101. The limiting block 24 is slidably disposed within the limiting groove 103, and the pushing block 23 is slidably disposed within the pushing groove 101. The bending pin seat 22 has a limiting square groove 104. The limiting spring 26 is disposed on the limiting block 24, and the pushing spring 25 is disposed on the pushing block 23. The movement of the push block 23 and the limit block 24 drives the bending pin 21 to precisely bend the copper wire to meet the winding shape requirements.

[0064] Outgoing and tail wire handling

[0065] After the winding is completed, the mold core 12 descends. At this time, the wire outlet clamping connecting block 14 in the upper mold clamping mechanism 6 is fixed to the outside of the upper mold assembly, and its lower end is fixed to the side end of the upper mold pad 4 by bolts. The wire outlet clamping block 17 and the wire outlet clamping spring 16 in the wire outlet clamping component 15 cooperate to clamp the wire outlet end of the wound coil.

[0066] Meanwhile, the locking pin connector 28 in the coil lead blocking mechanism 30 is bolted to the inner plane of the upper mold pad 4. The locking pin connector 28 has a locking pin groove 105. The wire blocking pin 27 and the locking pin spring 29 are set on the locking pin groove 105. The upper end of the wire blocking pin 27 passes through the upper mold cover 5 to limit the sliding position of the lead wire and ensure the stability of the lead wire.

[0067] Next, the cutting mechanism 13 is activated, the cutting connector 37 is bolted to the inside of the lower mold pad 9, the top of the cutting blade 36 in the cutting blade 35 is bent and extended to form a bent part, the cutting blade spring 38 is located between the bent part of the cutting blade 36 and the cutting blade connector 37, a sliding groove hole is opened on the cutting blade 36, the cutting blade fixing pin 39 is inserted into the groove hole, and the cutting blade 36 moves to cut off the excess wire ends.

[0068] Therefore, the mechanical structure of this utility model, employing the aforementioned inward-facing winding device for incoming and outgoing wires, can cooperate with automated programs to complete winding tasks for complex-shaped cables requiring specific molding processes. Its various mechanisms work collaboratively; for example, the mold core ensures the inner diameter of the coil, and the upper mold bending mechanism achieves precise bending of the copper wire. This allows it to handle diverse winding requirements, demonstrating the applicability and effectiveness of the device in complex winding scenarios.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
