[0053] Based on the above structure, the working method of the automated integrated wire cutting machine for fine leads of the present invention includes the following steps:

[0054] S1. Insert the lead wire coil into the wire feeding shaft 14 and tighten the locking knob 15;

[0055] S2, pull the lead end of the wire coil on the wire feeding shaft 14 so that the lead wire passes through the lead wire straightening mechanism 3, heating mechanism 4, wire feeding mechanism 5 and wire cutting mechanism 6 in one go;

[0056] S3. The equipment starts up. The wire feeding servo motor 12 and the power drive mechanism 7 work together to feed the wire. The wire feeding servo motor 12 feeds the wire, and the power drive mechanism 7 synchronously drives the wire feeding mechanism 5 to pull the lead wire.

[0057] S4. When the lead wire straightening mechanism 3 is working, the straightening drive motor 32 starts and drives the straightening drive wheel 33 to rotate. The straightening drive wheel 33 drives the straightening driven wheel 34 to rotate through the transmission belt 37.

[0058] S5. The straightening driven wheel 34 drives the rectangular frame 361 to rotate on two symmetrically arranged bearing support seats 35. As the rectangular frame 361 rotates, a number of straightening heads 1 363 and a number of straightening heads 2 364 make circular motion around the straightening hose 362, thereby pushing the lead wire inside the straightening hose 362 and straightening the lead wire.

[0059] S6. The straightened lead wire is fed into the heating tank 421. Due to the heating of the heating rod 43, the heating tank 421 has a certain temperature, which can heat the straightened lead wire to release stress.

[0060] 7. The wire feeding mechanism 5, under the elastic restoring force of the spring 518, enables the movable lead wire gripper 56 and the fixed lead wire gripper 57 to close and clamp the lead wire. After the movable lead wire gripper 56 and the fixed lead wire gripper 57 close and clamp the lead wire, the power drive mechanism 7 drives the wire feeding transmission assembly 513 to perform transmission, thereby causing the connecting rod structure composed of the wire feeding connecting rod 511 and the wire feeding rocker arm 512 to push the wire feeding slider 59 to move along the wire feeding guide rail 58, thereby causing the lead wire clamped by the movable lead wire gripper 56 and the fixed lead wire gripper 57 to move towards the wire cutting mechanism 6.

[0061] S8. After the wire feeding is completed, the power drive mechanism 7 provides driving force, causing the wire feeding link 51 to swing. The wire feeding link 51 pushes the flipping push plate 54 to flip around the rotating shaft mounting base 53.

[0062] S9. During the flipping process of the flipping push plate 54, the flipping push plate 54 pushes the push rod 55 to move, so that the lead wire movable clamp 56 and the lead wire fixed clamp 57 open, and the lead wire movable clamp 56 and the lead wire fixed clamp 57 no longer hold the lead wire. The power drive mechanism 7 drives the wire feeding slider 59 along the wire feeding guide rail 58, so that the lead wire movable clamp 56 and the lead wire fixed clamp 57 move away from the wire cutting mechanism 6.

[0063] S10, the lead wire cutting and fixing assembly 8 is working. The power drive mechanism 7 provides driving force. The planar linkage mechanism formed by the fourth link 81, the third rocker 82 and the third pusher 83 drives the fixed jaw 87 and the movable jaw 88 to close, clamping the lead wire for easy cutting.

[0064] S11, the wire cutting mechanism 6 is working. The power drive mechanism 7 provides driving force. The planar linkage mechanism formed by the second link 61, the second rocker arm 62, the second push rod 63, the second push plate 64 and the third link 66 drives the cutting guide wheel 610 to move along the back of the cutting blade 69. The cutting guide wheel 610 exerts downward pressure on the cutting blade 69, thereby cutting the lead wire. After the cutting guide wheel 610 returns to its initial position, the cutting blade 69 returns to its initial position at the second spring 68 so that the next cutting can be performed.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
