The beneficial effects of the present invention are as follows:

1. The present invention is provided with a rotating mechanism. When it is necessary to weld the bowl rack for placing bowls, after the sliding plate 1 is placed into the outer box of the dishwasher through the handle, since the sizes of different bowls placed are different, the sizes of the bowl racks required for welding are also different. The movement of the shoveling mechanism will drive the rotating shaft 1 to rotate, thereby driving the rotating disk to rotate. Before welding, the welding gun is placed in the insertion hole with a radius of the required welding bowl size, so as to facilitate the subsequent welding of the placement rack of a specific size. At the same time, the fan blade 1 at the bottom will also be driven to rotate, so as to blow the smoke generated by the welding upwards, so as to facilitate the subsequent collection and purification by the absorption mechanism.

2. The present invention sets a preheating mechanism. In the first circle of rotation of the rotating disk, the preheating mechanism will work first. The heater will quickly preheat the welding part locally before welding. Preheating can reduce welding stress, improve the fusion and strength of the weld, and reduce welding defects. After the rotating disk starts to rotate, the centrifugal force will stretch the telescopic spring, so that the sliding block moves along the second support column, thereby driving the scratch plate to scrape off the dust and stains on the heating plate first, so as to avoid the weakening of the subsequent heating effect. After that, the scratch plate will come into contact with the brush, and the brush will scrape off the dust attached to the scratch plate, thereby realizing self-cleaning.

3. The present invention sets a shoveling mechanism, and the magnetic blocks on the sliding plate 2 are attracted by the electromagnetic blocks on both sides, so as to control the sliding plate 2 to move back and forth along the support rod 3. During the movement, the cooperation of the rack and the gear 1 will drive the rotating shaft 1 to rotate, so that the rotating shaft 1 will rotate clockwise and counterclockwise. The clockwise rotation is the preheating process, and the counterclockwise rotation is the welding process. As the sliding plate 2 moves, the shoveling plate will also shovel the debris dropped on the sliding plate 2 during the welding onto the collecting plate.

4. The present invention sets a welding mechanism, and drives the sliding plate three to move by the rotation of the screw rod, thereby controlling the welding head to perform spot welding on the outer wall of the dishwasher outer box. During the welding process, the servo motor two will drive the motor shaft and the gear one to rotate, thereby driving the gear three and the shaft two to rotate, and then driving the fan blade two to rotate and generate wind force to make the argon gas entering the support block flow out from the air outlet pipe. At the same time, the winding rod will also move the copper wire along the direction of the control plate, so that the copper wire will melt and solidify at the welding point, thereby achieving the welding effect.

5. The present invention sets an absorption mechanism. After the exhaust device sucks the waste gas through the air inlet, it will enter the filter plate cylinder through the steam pipe 2. The impurities and small metal particles in the gas will be filtered between the filter plate 1 and the filter plate 2. At the same time, the cuprous chloride hydrochloric acid solution in the filter cylinder will produce a complex with the carbon monoxide in the waste gas, thereby purifying the waste. After that, the purified waste will enter the treatment cylinder through the outlet pipe 2 and react with the activated carbon to adsorb oxygen and carbon dioxide, and finally enter the gas storage cylinder, thereby realizing the reuse of argon.

When it is necessary to weld the bowl rack for placing bowls, after putting the sliding plate 671 into the outer box 7 of the dishwasher through the handle 673, since the sizes of different bowls are different, the sizes of the bowl racks required for welding are also different, and the height position of the rotating welding mechanism 67 can be changed by inserting the insertion plate 65 into the slots 64 of different heights.

As shown in FIG. 7 , the rotary welding mechanism 67 includes a sliding plate 671, a collecting plate 672 is symmetrically arranged at the bottom of the sliding plate 671, a handle 673 is fixedly connected to one end of the sliding plate 671 close to the inserting plate 65, shoveling mechanisms 675 are fixedly connected to both ends of the sliding plate 671, and a rotating mechanism 674 is evenly arranged on the top of the sliding plate 671;

The movement of the shoveling mechanism 675 drives the rotating shaft 6742 to rotate, thereby driving the rotating disk 6746 to rotate. Before welding, the welding gun 6748 is placed in the insertion hole 6747 of the required welding bowl size radius, so as to facilitate the subsequent welding of a specific size of the placement rack. At the same time, the fan blade 6743 at the bottom is also driven to rotate, so as to blow the smoke generated by welding upwards, so as to facilitate the subsequent collection and purification by the absorption mechanism 46.

In the first circle of rotation of the rotating disk 6746, the preheating mechanism 6749 will work first, and the heater will quickly preheat the welding part locally before welding. Preheating can reduce welding stress, improve the fusion and strength of the weld, and reduce welding defects. After the rotating disk 6746 starts to rotate, the centrifugal force will stretch the telescopic spring 67493, so that the sliding block 67495 moves along the support column 67494, thereby driving the scratch plate 67496 to first scrape off the dust and stains on the heating plate 67491, so as to avoid the subsequent weakening of the heating effect. After that, the scratch plate 67496 will come into contact with the brush 67499, and the brush 67499 will scrape off the dust attached to the scratch plate 67496, thereby realizing self-cleaning.

The electromagnetic blocks 6752 on both sides attract the magnetic blocks 6755 on the sliding plate 2 6754, thereby controlling the sliding plate 2 6754 to move back and forth along the support rod 3 6753. During the movement, the rack 6756 and the gear 1 6745 cooperate to drive the shaft 1 6742 to rotate, thereby causing the shaft 1 6742 to rotate clockwise and counterclockwise. The clockwise rotation is the preheating process, and the counterclockwise rotation is the welding process. As the sliding plate 2 6754 moves, the shoveling plate 6757 will also shovel the debris dropped on the sliding plate 2 6754 during welding onto the collecting plate 672

The specific workflow is as follows:

During operation, after the sliding plate 1 671 is placed into the outer box 7 of the dishwasher through the handle 673, the magnetic blocks 6755 on the sliding plate 2 6754 are attracted by the electromagnetic blocks 6752 on both sides, so as to control the sliding plate 2 6754 to move back and forth along the support rod 3 6753.

The forward rotation is the preheating process, and the counterclockwise rotation is the welding process. As the sliding plate 2 6754 moves, the shoveling plate 6757 will also shovel the debris dropped on the sliding plate 2 6754 onto the collecting plate 672. The movement of the shoveling mechanism 675 will drive the rotating shaft 1 6742 to rotate, thereby driving the rotating disk 6746 to rotate. Before welding, put the welding gun 6748 into the required welding bowl size. The small radius insertion hole 6747 is used to facilitate the subsequent welding of a placement rack of a specific size. At the same time, the fan blade 6743 at the bottom will also be driven to rotate, thereby blowing the smoke generated by welding upward. In the first circle of rotation of the rotating disk 6746, the preheating mechanism 6749 will work first, and the heater will perform local rapid preheating of the welding part before welding. Preheating can reduce welding stress, improve the fusion and strength of the weld, and reduce welding defects. After the rotating disk 6746 starts to rotate, the centrifugal force will cause the telescopic spring 67493 to stretch, thereby causing the sliding block 67495 to move along the support column 67494, thereby driving the scratch plate 67496 to first scrape off the dust and stains on the heating plate 67491, thereby avoiding the subsequent weakening of the heating effect. After that, the scratch plate 67496 will come into contact with the brush 67499, and the brush 67499 will scrape off the dust attached to the scratch plate 67496.
