[0050] This application is used to weld the switch motherboard welder. First, the overall equipment is positioned by welding the main box 1. The welding host 2 is installed inside the welding main box 1. Then, the motherboard moving limit mechanism moves inside the limit movable groove 4 and cooperates with the motherboard fixed limit mechanism to realize the limit fixation of switch motherboards of different sizes. The relay clamping limit mechanism clamps the relay and places the relay on the switch motherboard to achieve compression and fixation. When in use, first place the switch motherboard on the welding table 3.

[0051] The mainboard movement limiting mechanism includes a movable base plate 5, which is slidably plugged and installed on the welding main box 1 through two T-shaped slides 6. A first adjusting screw 7 is rotatably installed on the movable base plate 5 along the length direction. Both ends of the first adjusting screw 7 extend to the outside of the movable base plate 5. One end of the first adjusting screw 7 is fixedly installed with a first adjusting handle 8, and the other end is provided with a threaded end 9, which is spirally matched with the welding main box 1.

[0052] The motherboard movement limit mechanism realizes displacement by movably plugging the movable base plate 5 and the two T-shaped slides 6 into the interior of the welding main box 1. The threaded end 9 of the first adjusting screw 7 is screwed with the welding main box 1 to realize movement close to and then away from the motherboard fixed limit mechanism, thereby adapting to switch motherboards of different sizes.

[0053] A second adjusting bolt 10 is also screwedly installed on the movable base plate 5, and an L-shaped transmission limit plate 11 is rotatably installed on the upper part of the second adjusting bolt 10. The L-shaped transmission limit plate 11 slides with the limit movable groove 4. The top of the L-shaped transmission limit plate 11 extends to the top of the welding table 3 and is fixedly installed with a first limit pressure plate 12.

[0054] Rotating the second adjusting bolt 10 can drive the L-shaped transmission limit plate 11 to achieve lifting and lowering displacement. When the L-shaped transmission limit plate 11 moves to fit the side of the switch mainboard, adjusting the second adjusting bolt 10 makes the first limit pressure plate 12 press the edge surface of the switch mainboard, thereby fixing and pressing one side of the switch mainboard.

[0058] The relay clamping limit mechanism can drive the slide rail 18 to rotate to any angle by rotating the adjusting column 17, and then the upper slider 19 is slidably installed on the slide rail 18, so that the upper slider 19 can be adjusted to any position on the welding machine table, and then the edge of the relay is clamped by two fourth clamping plates 22, and the height of the clamping limit block 21 is adjusted by rotating the fourth adjusting screw 20, driving the clamping limit block 21 to clamp the relay and the switch mainboard, thereby fixing the welding position.

[0059] The welding host 2 is connected to a welding gun 25 via a welding line 24 .

[0060] After the switch mainboard and the relay are fixed, they are welded using a welding gun 25 .

[0061] The top view cross section of the welding main box body 1 is rectangular, and the rotation adjustment column 17 is located at any corner of the welding main box body 1 .
