After welding is completed, the baffle 2727 can also automatically reset as the clamping is released.
[0024] In summary, when using the welding device for processing electrical connectors, the air pump 11 is first started. The air pump 11 establishes a negative pressure in the air passage 5 of the shaft 201 through the air extraction pipe 10. The air in the wire placement groove 210 enters the second sleeve group 9 from the air extraction hole 8 through the air extraction groove 7, and then enters the air passage 5 from the air extraction port 6, thereby forming an adsorption force at the air extraction groove 7. Then, the rotating wheel 3 is manually rotated and the wiring harness is placed in the corresponding wire placement groove 210 in sequence according to the position of the welding point on the electrical connector. The wiring harness that exceeds the length of the shaft 201 can be placed in the through groove 4. The adsorption force at the air extraction groove 7 can firmly adsorb the wiring harness in the wiring groove 210, so that when the rotating wheel 3 rotates, the wiring harness can be driven to move together with the shaft 201 to avoid entanglement between the wiring harnesses. After the wiring harness is placed, the electrical connector is placed inside the swivel 20, and the pins of the electrical connector and the welding end of the wiring harness are located on the same plane. Then the telescopic rod 22 drives the clamping plate 23 to move to clamp the electrical connector, and the follower rod 24 can move synchronously with the clamping plate 23. Because the initial positions of the clamping plate 23 are located at the upper, lower, front and back four directions of the swivel 20, when the clamping plate 23 moves, the clamping plates 23 on both sides can make the follower rod 24 drive the baffles 27 on both sides of the chassis 1 through the follower block 28 to move synchronously. The baffle 27 is moved so that the edge of one side close to the electrical connector is always close to the outer wall of the electrical connector, so that the baffle 27 can separate the pin side of the electrical connector into two parts, the upper and lower parts, thereby separating the welding area and the cooling area, avoiding the mutual influence of hot and cold air flows during the welding process, and automatically adapting to electrical connectors of different sizes without manual adjustment of the baffle 27. During the movement of the baffle 27, the slide groove 25 can limit the baffle 27 through the slide rod 26 to ensure the stability of the baffle 27 and prevent the baffle 27 from deflecting. After the electrical connector is clamped, the push rod 203 can drive the air plate 204 to move in the ventilation cavity 202, and squeeze the air in the ventilation cavity 202 into the ventilation groove 205 through the vent hole 206, and squeeze it into the first sleeve group 208 through the vent hole 207, so that the first sleeve group 208 drives the material plate to expand outward on the shaft 201 synchronously, so that the material plate drives the welding end of the wire harness to connect with the pin on the electrical connector. When the material plate moves, the baffle 27 can limit the movement distance of the material plate. When the material plate contacts the baffle 27, the push rod 203 stops pushing the air plate 204 to prevent the material plate from moving too much and causing the wire harness to be unable to connect accurately. When the material plate moves, the second sleeve group 9 can follow the material plate to expand synchronously to ensure the connection between the exhaust groove 7 and the air duct 5; After the wire harness is moved into place, the welding wire reel is installed on the feeding mechanism 29, and the end is pulled to the first welding point. The direction of the nozzle 16 is then adjusted by the spherical joint so that the airflow ejected by the nozzle 16 can be aimed at the welding point. Then the heat exchange plate 14 is started. After the air extracted by the air pump 11 enters the heat exchange box 12, the heat exchange plate 14 can cool the air below the partition 13 and dissipate the heat to the top of the partition 13 to heat the air above the partition 13. The partition 13 can isolate the air in the upper and lower parts of the heat exchange box 12 to avoid heat exchange between the air flows, which may cause the temperature of the cold and hot air flows to not meet the requirements. After the hot air flow is ejected from the hot air pipe 15 through the nozzle 16 to the welding point, hot air welding can be carried out. After a welding point is completed, the motor 19 drives the wheel shaft 18 to rotate, which can drive the rotating ring 20 and the rotating wheel 3 to rotate synchronously, and synchronously adjust the position of the electrical connector and the wiring harness, so as to weld the next welding point. After the welding is completed, the welding point moves below the baffle 27, and the cold air flow is ejected through the cold air pipe 17 to cool the welding point, thereby accelerating the cooling of the welding point. After all welding is completed, turn off the heat exchanger and air pump 11. After the wheel 3 rotates back to its initial position, turn off the motor 19. At the same time, push the rod 203 to drive the air plate 204 to reset, so that the wire placement plate 209 is synchronously contracted inward on the shaft 201, so that the material placement plate is away from the wire harness. Then, grab the electrical connector and use the telescopic rod 22 to drive the clamping plate 23 to reset. Take the electrical connector together with the wire harness out of the inner side of the swivel 20, and then you can start welding the next electrical connector.
