[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The driving assembly includes a gear 81, a rack 1 82, a rack 2 83, a connecting rod 84 and a connecting rod 85. The gear 81 is fixedly sleeved on the rotating shaft 6. The rack 1 82 and the rack 2 83 are respectively placed on both sides of the gear 81, and the rack 1 82 and the rack 2 83 are fixedly connected through the connecting rod 84. One end of the connecting rod 85 is fixedly connected to the rack 1 82, and the other end of the connecting rod 85 is fixedly connected to the moving seat 2. The connecting rod 85 passes through the strip opening 4 and slides in the strip opening 4. The sliding assembly includes two plates 1 91, a slider 1 92, two rods 1 93, a fixed plate 94, two plates 2 95, two rods 2 96, a spring 97 and a slider 2 98. The two plates 1 91 are fixed on the frame 1, the two rods 1 93 are fixed between the two plates 1 91, the slider 1 92 is slidably sleeved on the two rods 1 93, and during the movement of the slider 2 98, the slider 1 9 2 and the two rods 1 93 limit the movement of the slider 2 98, thereby ensuring the stability of the slider 2 98 during movement. In addition, the slider 1 92 and the rod body 93 are made of rubber material, which makes the slider 1 92 and the rod body 93 have a sufficiently large friction force to prevent the slider 1 92 from moving without force, thereby ensuring the position stability of the rack 1 82 and the rack 2 83. The two plates 2 95 are respectively fixed at the upper and lower ends of the fixed plate 94, and the two rods 2 96 are fixed between the two plates 2 95. The slider 2 98 is slidably sleeved on the two rods 2 96. When the rack 1 82 moves downward, the slider 2 98 and the two rods 2 96 limit the movement of the rack 1 82, and the slider 2 98 is fixedly connected to the rack 1 82. One end of the spring 97 is connected to the slider 2 98, and the other end is connected to one of the plates 2 95.
[0026] The control component includes magnet one 101, magnet two 102 and magnet three 103, magnet one 101 and magnet two 102 are all fixed on the frame 1, magnet three 103 is fixed on the slider two 98, the magnetic poles of magnet one 101 and magnet three 103 are the same poles, and the magnetic poles of magnet two 102 and magnet three 103 are opposite poles. When the movable seat 2 moves up and down, gear one 82 and gear two 83 can alternately drive the rotating shaft 6 to rotate, which makes the several axial flow blades 7 continuously perform the exhaust action, so as to absorb the smoke generated during the spot welding process. Furthermore, gear one 82 and gear two 83 can be alternately driven to avoid the existence of a window period in the exhaust action, so as to ensure the device's absorption effect on the smoke.
[0027] The specific working principle of the utility model is as follows:
[0028] When the varistor processing pin welding device proposed by the utility model is used, in the initial state, the movable seat 2 is located at the upper limit position, and the magnetic block 3 103 is arranged opposite to the magnetic block 1 101. Since the magnetic poles of the magnetic block 1 101 and the magnetic block 3 103 are the same, under the effect of the same poles repelling each other, the magnetic block 3 103 is located away from the magnetic block 1 101. At this time, the rack 1 82 is meshed with the gear 81, and the rack 2 83 is not meshed with the gear 81;
[0029] When spot welding the pins of the varistor, the staff puts the pins of the varistor between the movable seat 2 and the fixed seat 3. Then, the movable seat 2 moves downward to cooperate with the fixed seat 3 to complete the spot welding of the pins of the varistor. When the movable seat 2 moves downward, it can drive the rack 82 to move downward through the connecting rod 85. When the rack 82 moves downward, it can drive the gear 81 to rotate, and the shaft 6 will also rotate accordingly. When the shaft 6 rotates, it can drive the plurality of axial flow blades 7 to rotate. When the plurality of axial flow blades 7 rotate, During the air pumping operation, during the downward movement of rack 1 82, slider 2 98 and two rods 2 96 limit the movement of rack 1 82. When the movable seat 2 moves to the lower limit position, slider 2 98 moves to the position facing magnet 2 102. At this time, magnet 3 103 is arranged facing magnet 2 102. Since the relative poles of magnet 2 102 and magnet 3 103 are opposite, magnet 3 103 will move towards the direction close to magnet 2 102 under the effect of attraction of opposite poles, and bring The movable slider 2 98 moves, and when the slider 2 98 moves, it can drive the rack 1 82 to move. When the rack 1 82 moves, it can drive the rack 2 83 to move through the connecting rod 84. When the magnetic block 2 102 and the magnetic block 3 103 are attracted to each other, the rack 1 82 is separated from the gear 81, and the rack 2 83 is meshed with the gear 81. Further, the movable seat 2 moves up and resets. When the movable seat 2 moves up, it can drive the rack 1 82 to move up through the connecting rod 85, and the rack 2 83 will also move up. In this process, the rack 2 83 can drive the gear 81 to rotate, and the rotating shaft 6 and the plurality of axial flow blades 7 will also rotate accordingly. Based on the above process, when the movable seat 2 moves up and down, the gear 1 82 and the gear 2 83 can alternately drive the rotating shaft 6 to rotate, which makes the plurality of axial flow blades 7 continuously perform the exhaust action, thereby absorbing the smoke generated during the spot welding process. Further, the gear 1 82 and the gear 2 83 can be driven alternately to avoid the window period of the exhaust action, thereby ensuring the device's absorption effect on the smoke.
[0030] It is worth mentioning that during the movement of slider 2 98 , slider 1 92 and two rods 1 93 limit the movement of slider 2 98 , thereby ensuring the stability of slider 2 98 during the movement. In addition, slider 1 92 and rod body 93 are both made of rubber material, which ensures that there is sufficiently large friction between slider 1 92 and rod body 93 to prevent slider 1 92 from moving without force, thereby ensuring the position stability of rack 1 82 and rack 2 83 .
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
