The position distance between the two groups of placement tables 5 is detected by the laser displacement ranging sensor 91 and the measuring circular plate 92 in the distance detection mechanism 9, so as to achieve precise control of the distance between the placement tables 5, so as to adjust the accuracy of the spacing between the parts to be welded, and utilize The residue collection box 10 collects welding residues. The box body 101 in the residue collection box 10 is composed of silica gel 103 and ceramic coating 104, which makes the residue collection box 10 have the advantages of being deformable and high-temperature resistant, avoiding hindering the movement of the placement table 5. The use of ceramic coating 104 can also prevent high temperature from affecting the safety of the residue collection box 10. The touch screen 3 and the PLC controller are used to monitor and control the moving mechanism 4, the limiting mechanism 6, the shell 61, the plumb line 7 and the electrical components in the distance detection mechanism 9 to adjust the position accuracy of the parts to be welded.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
