A magnetic shielding layer is provided on the outside of the heat-resistant magnetic column 35.

[0021] A controller 31 is provided on the side wall of the conductor platform 1.

[0022] The controller 31 is electrically connected to the drive motor 6, the coupling electromagnet 25 and the sliding electromagnet 33 respectively.

[0023] In actual use, initially, the guide spring 12 is in an extended state, and the sliding drive spring 20 is initially in a compressed state. Multiple sets of terminals are inserted between the heat-resistant rubber layers 15 inside the clamping box 14. The terminals are clamped inside the clamping box 14 by the deformation of the heat-resistant rubber layers 15. The controller 31 controls the activation of the electromagnet 25. The electromagnet 25 is energized and generates magnetism. The electromagnets 25 are set with the same pole. The electromagnets 25 repel each other due to the repulsive magnetic field generated and move in opposite directions. The electromagnet 25 pushes the sliding block 19 through the arc rod 22. The sliding block 19 drives the guide post 18 to rotate by the elastic deformation of the sliding drive spring 20. The circular cavity formed by the two sets of half rubber tubes 24 is opened. The wire harness is placed between the half rubber tubes 24. The end of the wire harness away from the half rubber tube 24 is placed on the bottom wall of the arc groove 2. Then the electromagnet 25 is de-energized and demagnetized. The sliding drive spring 20 elastically resets and drives the sliding block 19 to rotate through the guide post 18. The sliding block 19 drives the wire clamping block 23 to move relative to each other through the arc rod 22. The wire clamping block 23 drives the half rubber tube 24 to clamp the wire harness. The controller 31 controls the start of the sliding electromagnet 33. The sliding electromagnet 33 is energized and generates magnetism. The sliding electromagnet 33 and the sliding magnetic block 32 are set with opposite poles. The sliding electromagnet 33 is fixed to the side wall of the welding table 3 and magnetically attracts the sliding magnetic block 32. The sliding magnetic block 32 uses the deformation of the sliding spring 20 to drive the sliding block 19 to slide along the guide post 18. The sliding block 19 drives the wire clamping block 23 to move closer to the welding table 3 through the arc rod 22. The wire clamping block 23 drives the wire harness to move to the welding table surface of the welding table 3 through the half rubber sleeve 24. At this time, the metal wire of the wire harness is located on the upper wall of the terminal. The ultrasonic welding equipment is moved to one side of the welding table 3. The ultrasonic welding equipment presses the metal wire and terminal down onto the table surface of the welding table 3. Under the pressure of the ultrasonic welding equipment, the wire harness is pulled out from between the half rubber cylinders 24 to avoid excessive pulling of the wire harness. The bottom wall of the clamping box 14 is in contact with the bottom wall of the welding groove 34, and the bottom wall of the terminal is in contact with the table surface of the welding table 3. The ultrasonic welding equipment generates heat through high-frequency vibration and friction, causing the metal atoms on the contact surface to diffuse and combine in the solid state, thereby achieving the welding of the wire harness and the terminal. After the wire harness metal wires and terminals are pressed together on the welding table 3, the controller 31 controls the electromagnet 25 to be energized and generate magnetism. The electromagnet 25 is set with opposite poles. The inner diameter of the cavity formed by the splicing of the half rubber cylinders 24 is smaller than the outer diameter of the wire harness. Under the mutual attraction of the electromagnets 25, the half rubber cylinders 24 are squeezed and spliced ​​together to complete the clamping of the wire harness. This facilitates the pull-out test of the welded wire harness and ensures the welding quality between the wire harness metal wires and terminals. Under the same welding process parameters, the larger the cross-sectional area of ​​the wire, the longer the welding time is usually, and the more heat is output from the welding area. The heat-conducting copper rod 27 conducts heat out of the welding area. The soft iron block 30 moves with the clamping block 23 and reduces the distance between itself and the heat-conducting copper rod 27. The heat-resistant bar magnet 29 magnetizes the soft iron block 30 above it. The soft iron block 30 and the heat-resistant bar magnet 29 are set with opposite poles. The heat-conducting copper rod 27 uses the heat it conducts to heat the soft iron block 30. After the soft iron block 30 is heated, the magnetic field weakens. The magnetic field strength between the heat-resistant bar magnet 29 and the soft iron block 30 weakens accordingly, so that the sliding spring 20 can pull the terminal through the metal wire at a faster rebound speed. The terminal is pulled out from between the heat-resistant rubber layers 15. The smaller the cross-sectional area of ​​the conductor, the shorter the welding time is usually, and the less heat is output from the welding area. This results in less heating heat from the thermally conductive copper rod 27 to the soft iron block 30, and a stronger magnetic field between the heat-resistant strip magnet 29 and the soft iron block 30. Consequently, the sliding spring 20 pulls the terminal through the metal conductor at a slower rebound speed. After the terminal is pulled out from the clamping box 14 by the metal wire, the controller 31 controls the electromagnet 25 to start. The electromagnet 25 is energized and generates the same polarity magnetism. The clamping blocks 23 move in opposite directions, taking out the welded wire bundle and terminal from the clamping blocks 23 and the arc groove 2, and placing the next set of wire bundles. This not only completes the unloading of the welding area, but also realizes the above-mentioned welding quality pull test. It can also prevent the thin wire bundle from being torn off under high pulling speed and strength, thereby ensuring the safety and reliability of the test. Subsequently, the controller 31 controls the drive motor 6 to start, and the drive motor 6 drives the drive frame 7 to rotate through the power end. The drive frame 7 drives the sliding plate 11 to rotate through the guide ring disk 9. The sliding plate 11 drives the next set of terminals to enter the table surface of the welding station 3 through the clamping box 14, waiting for the ultrasonic welding equipment to perform the downward welding operation. The above operation can be repeated for the next use.
