[0034] The welding process of copper Hukou welding equipment based on pulse laser hybrid welding technology has the following steps:

[0035] S1: By putting the copper pot on the round box 5, starting the cylinder 36 to drive the two lifting plates 37 to move upward, driving the pressure rod 35 to move upward to squeeze the air in the pressure tube 3 into the round box 5, the air will enter the square tube 6 and drive the moving bar 7 to move, and the moving bar 7 drives the soft board 8 to move and squeeze the inner wall of the copper pot to fix the copper pot.

[0036] S2: By inserting the spout into the positioning groove 26 and starting the air pump 12, air can be injected into the air bag 25 to expand the spout and squeeze the spout to fix the spout.

[0037] S3: The position of the copper kettle's welding joint can be monitored by the visual monitoring device 17, and the position of the copper kettle can be adjusted by rotating the rotating plate 10 back and forth through the rack 9 via the rotary drive 2, so that the welding joint of the copper kettle is adjusted to be aligned with the spout.

[0038] S4: After the gas enters the square tube 6 from the round box 5, it can squeeze the movable plug 24 to move, and the moving bar 7 can be squeezed by the pressure spring 23. The squeezing of the pressure spring 23 can fix the copper pot while providing a certain buffer space to avoid excessive squeezing force to damage the copper pot.

[0039] When in use, the first step is: by putting the copper kettle that needs to be fixed on the round box 5, the two lifting plates 37 can be driven upward by the cylinder 36, thereby driving the pressure rod 35 to move upward, so that the air in the pressure tube 3 can be squeezed into the round box 5, and then the air will enter the square tube 6, so that the moving bar 7 can be driven to move, thereby driving each soft plate 8 to move and squeeze the inner wall of the copper kettle, so that the copper kettle can be fixed. After inserting the spout into the positioning groove 26 and starting the air pump 12, air can be injected into the airbag 25 to expand it and squeeze the spout to fix the spout, so that the user can quickly fix the copper kettle and the spout.

[0040] Step 2: The position of the copper kettle's welding joint can be monitored by the visual monitoring device 17, and then the position of the copper kettle can be adjusted by rotating the rotating plate 10 back and forth through the rack 9 via the rotary drive 2, so that the welding joint of the copper kettle can be adjusted to align with the spout.

[0041] Step 3: After the gas enters the square tube 6 from the round box 5, it can squeeze the movable plug 24 to move, so that the movable bar 7 can be squeezed by the pressure spring 23. In this way, the copper pot can be fixed by the squeezing of the pressure spring 23 while providing a certain buffer space to avoid excessive squeezing force to damage the copper pot.

[0042] Step 4: By cooperating with the limiting groove 20 of the limiting rod 22 and the limiting block 21, the moving bar 7 can be smoothly sucked back when the pressure rod 35 moves downward and starts to inhale, so that the user can easily remove the copper kettle.

[0043] Step 5: By rotating the rotating ring 32 downward, the sealing ring 30 can be driven to move downward to expose the air port 33. In this way, the screw 14 can be driven by the rotating disk 15 to rotate up and down to adjust the initial position of the circular plate 39, so that the internal air volume can be adjusted. At the same time, the sealing ring 30 is moved upward to block the air port 33 and then the position of the circular plate 39 is moved up and down. In this way, the initial position of the soft board 8 can be adjusted, so that the user can adjust it according to the size of the copper pot, so that copper pots of different sizes can be fixed.
