[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0030] like Figure 1-Figure 5As shown, the utility model provides a welding device for resistance processing, including a welding gun 1, a tin-through hole 2 is opened in the welding gun 1, a heater 3 is fixedly connected to the surface of the welding gun 1, a soldering iron tip 4 is fixedly connected to the heating end of the heater 3, a purification structure 5 is provided on the surface of the welding gun 1, and the purification structure 5 includes an air suction pump 501, the air suction pump 501 is fixedly connected to the welding gun 1, the air inlet end of the air suction pump 501 is fixed and communicated with a first frame 502, the first frame 502 is fixedly connected to the welding gun 1, and a second frame 503 is fixedly connected to the surface of the welding gun 1. The first frame 502 and the second frame The inner wall of 503 is snap-connected with a connecting pipe 504, and the connecting pipe 504 is filled with a filter element 505. The surface of the second frame 503 is fixed and connected with a bending pipe 506, and one end of the bending pipe 506 is fixed and connected with an air intake hood 507. The arc surface of the connecting pipe 504 is fixedly connected with an L-shaped plate 508, and the surface of the welding gun 1 is fixedly connected with a round rod 509. The arc surface of the round rod 509 is rotatably connected with a rotating plate 510. The rotating plate 510 is slidably connected to the L-shaped plate 508. The rotating plate 510 prevents the L-shaped plate 508 from moving upward, thereby preventing the connecting pipe 504 from moving.
[0031] like Figure 2-Figure 5 As shown, the arc surface of the round rod 509 is covered with a torsion spring 511, and the two ends of the torsion spring 511 are fixedly connected to the welding gun 1 and the rotating plate 510 respectively. The torsion spring 511 will use its own torsion to rotate the rotating plate 510 and contact with the L-shaped plate 508. The surface of the rotating plate 510 is provided with a plurality of anti-slip grooves 512. The anti-slip grooves 512 can facilitate the rotation of the rotating plate 510. The arc surface of the connecting pipe 504 is fixedly connected to the clamping plate 514, and the surface of the welding gun 1 is fixedly connected to the U-shaped plate 513. The U-shaped plate 513 is slidably connected to the clamping plate 514. The U-shaped plate 513 limits the moving path of the clamping plate 514, thereby limiting the connection. To control the moving path and position of the connecting pipe 504, a guide plate 515 is fixedly connected to the lower surface of the card plate 514, and the guide plate 515 is a step structure. After the guide plate 515 with a step structure comes into contact with the U-shaped plate 513, it can guide the moving path of the card plate 514, making it convenient for the card plate 514 to slide into the U-shaped plate 513. Both ends of the connecting pipe 504 are fixedly connected with a sealing ring 516, and the two sealing rings 516 are respectively slidably connected to the first frame 502 and the second frame 503. The sealing ring 516 serves to improve the sealing between the connecting pipe 504 and the first frame 502 and the second frame 503.
[0032] The overall working principle is that when processing the carbon film wafer resistor, the solder wire is passed through the tin hole 2, and the soldering iron tip 4 is heated by means of the heater 3. When the solder wire contacts the soldering iron tip 4, it will be melted, and then the carbon film wafer resistor is processed with the melted solder. When it is necessary to deal with the generated smoke, the rotating plate 510 is first turned. At this time, the anti-slip groove 512 serves to facilitate the rotation of the rotating plate 510. The rotation of the rotating plate 510 will twist the torsion spring 511, so that the torsion spring 511 is in a twisted state, and then the connecting tube 504 is moved. The card plate 514 moves with the movement of the connecting tube 504 and drives the guide plate 515 to move. After the guide plate 515 with a step structure contacts the U-shaped plate 513, it can guide the moving path of the card plate 514, making it convenient for the card plate 514 to slide into the U-shaped plate 513. The U-shaped plate 513 limits the moving path of the card plate 514, thereby limiting the connecting tube 504 moves along the path and position of movement, and then the connecting pipe 504 will contact the first frame 502 and the second frame 503, and the sealing ring 516 will improve the sealing between the connecting pipe 504 and the first frame 502 and the second frame 503, and then the rotating plate 510 will be loosened, and the torsion spring 511 will use its own torque to rotate the rotating plate 510 and contact with the L-shaped plate 508, and the rotating plate 510 will prevent the L-shaped plate 508 from moving upward, thereby preventing the connecting pipe 504 from moving, and then turn on the suction pump 501. At this time, the air around the air intake hood 507 will flow into the air intake hood 507, and the air flow will drive the smoke to flow, thereby preventing the smoke from spreading to the surroundings. After that, the smoke will pass through the bending tube 506 and the second frame 503 and be filtered by the filter element 505, thereby absorbing the smoke, preventing the smoke from polluting the surrounding air, and ensuring the comfort of the staff.
