[0025] Working principle: When the present invention is used, the specific operating steps are as follows: Step 1: First place the OT terminal on the fixing piece 1 5, and place the wire on the fixing piece 2 6; Step 2: Then open the electric push rod 4, and the movable end of the electric push rod 4 is extended to drive the mounting plate 11 to move downward, thereby driving the straight connecting frame 10 and the welding machine body 12 to move downward, thereby driving the connecting rod 9 to move downward along the vertical groove 1501 and the vertical groove 2 1601 respectively, releasing the support for the pressure plate 1 502 and the pressure plate 2 602, and then under the action of the reset spring 1 506 and the reset spring 2 604, the OT terminal and the wire are fixed; When one of the connecting rods 9 moves to the hinge of the inclined slot 1 1502, the other connecting rod 9 also moves along the vertical slot 2 1601; Then, when the connecting rod 9 moves along the inclined groove 1502, the connecting rod 9 moves toward the side close to the welding machine body 12, thereby driving the L-shaped connecting frame 8 to move toward the side close to the welding machine body 12, thereby realizing the movement of the OT terminal toward the side of the welding machine body 12; When one of the connecting rods 9 moves along the inclined groove 1 1502, the other connecting rod 9 continues to slide along the vertical groove 2 1601. When the connecting rod 9 moves to the intersection of the inclined groove 1 1502 and the falling groove 1 1503, the other connecting rod 9 moves to the entrance of the inclined groove 2 1602. Step 3: When the connecting rod 9 just enters the drop groove 1503, the connecting rod 9 contacts the pressure sensor 35. The pressure sensor 35 receives the signal and transmits the signal to the processor in the control device 2. The processor processes the signal and controls the controller to stop the electric push rod 4 and power on the electric telescopic rod 13 to open. Here, the position where the movable end of the electric telescopic rod 13 is fully extended is recorded as point A, the position where the movable end of the electric telescopic rod 13 moves to the bar-shaped toothed plate 28 and contacts the limit rod 14 is recorded as point B, and the position where the movable end of the electric telescopic rod 13 is fully retracted is recorded as point C; Step 4: When the movable end of the electric telescopic rod 13 is controlled to move from point A to point B, during this process, the movable end of the electric telescopic rod 13 contracts to drive the rectangular frame 19 to move, and then the movable block 27 moves synchronously with the rectangular frame 19 under the action of the extrusion spring 29, thereby driving the bar-shaped toothed plate 1 28 to move, so that the gear 2 18 rotates, and further drives the connecting shaft 26 to rotate, so as to release the traction rope 24, and then the baffle 20 is reset under the action of the extrusion spring 1 21, so as to shield the front end surface of the box body 1, avoid splashing of high-temperature liquid during welding, thereby avoiding the operator from being scalded, and further facilitating the operator to protect; When the bar-shaped toothed plate 1 28 contacts the limiting rod 14, the bar-shaped toothed plate 1 28 will not move, and the bar-shaped toothed plate 2 30 is meshed with the gear 1 17; Step 5: When the movable end of the electric telescopic rod 13 is controlled to move from point B to point C, during this process, the rectangular frame 19 continues to move to drive the bar-shaped toothed plate 2 30 to move, and then drives the gear 1 17 to rotate, thereby realizing the rotation of the screw rod 31, and the rotation of the screw rod 31 drives the threaded sleeve 36 to move, and then drives the rectangular box 32 to move, thereby driving the cleaning handle 33 to move, so as to clean the welding position of the OT terminal for the welding of the OT terminal; Then, the movable end of the electric telescopic rod 13 is controlled to move back and forth between point B and point C, thereby realizing the reciprocating movement of the cleaning handle 33 to clean the welding part of the OT terminal; Step 6: After the OT terminal is cleaned, the movable end of the electric push rod 4 is controlled to move downward to drive the mounting plate 11 to continue to move. At this time, one of the connecting rods 9 moves along the falling groove 1503, and the other connecting rod 9 moves along the inclined groove 2 1602, thereby realizing the movement of the fixing member 2 6, further driving the wire to move, and when the connecting rod 9 moves into the falling groove 2 1603, at this time, the wire and the OT terminal are connected; As the movable end of the electric push rod 4 continues to move downward, the welding machine body 12 will move downward, while the fixing member 1 5 and the fixing member 2 6 will not move any more. Finally, the welding machine body 12 falls at the junction of the OT terminal and the wire. Step 7: Finally, the electric push rod 4 is controlled to make the welding machine body 12 weld the OT terminal and the wire; After welding is completed, repeat step 5 to clean the residue at the welding position; Then, the first pressing plate 502 and the second pressing plate 602 are lifted upward to release the fixation of the OT terminal, and then the OT terminal is removed. Finally, the movable end of the electric push rod 4 is controlled to contract to reset each component.
