[0028] When in use, first place the bottom plate in the middle of the base 1, then place the side plate on the vacuum suction cup 810, and fix the side plate by suction. Just start the rotating motor 704, the rotating motor 704 drives the rotating plate 708 to rotate, the rotating plate 708 drives the moving ring 711 to reciprocate back and forth, and the moving ring 711 drives the moving plate 710 and the rectangular rubber plug 709 to reciprocate back and forth. When the rectangular rubber plug 709 moves backward, the limiting ball 806 moves downward under the suction force, the control spring 804 is compressed, and the limiting ball 805 is kept under the limit of the fixed ring 809. At this time, the interior of the rectangular cylinder 801 is connected with the interior of the air collecting box 802, so that the air in the air collecting box 802 is sucked into the rectangular cylinder 801. When the rectangular rubber plug 709 moves forward, the limiting ball 806 is forced to reset and remains stationary under the limit of the rectangular cylinder 801. The limiting ball 805 is pushed outward, and the control spring 803 is compressed. At this time, the interior of the rectangular cylinder 801 is connected with the outside world, so that the air in the rectangular cylinder 801 is pushed to the outside world, so that the air in the air collecting box 802 is gradually discharged to form negative pressure, so that the side plate is firmly adsorbed on the vacuum suction cup 810;Then, the bottom plate is fixed, and the side plate is fixed and placed at the same time, and the moving motor 502 is started. The moving motor 502 drives the screw rod 501 to rotate, and the screw rod 501 drives the T-shaped plate 503 to move from both ends to the middle, and the T-shaped plate 503 drives the entire bottom plate end surface automatic fixing component 5 and the bottom plate top automatic fixing component 6 to move toward the middle together, and the bottom plate top automatic fixing component 6 drives the entire side plate automatic placement mechanism 3 to move toward the middle. When the L-shaped block 504 contacts the end surface of the bottom plate, under the continued movement of the T-shaped plate 503, the L-shaped block 504 moves backward along the U-shaped block 506, and the L-shaped block 504 drives the fixed plate 507 to move backward, and the fixed plate 507 drives the connecting rod 605 to rotate, and the connecting rod 605 drives the rotating column 602 to rotate, and the rotating column 602 drives the flip plate 603 to rotate, and the flip plate 603 drives the columnar tube 606, the extrusion column 604 and the entire side plate automatic placement mechanism 3 to rotate together until the L The shape block 504 is in close contact with the rectangular block 505, and the end surface of the bottom plate can be fixed. At this time, the connecting rod 605 is rotated exactly 90 degrees, that is, the extrusion column 604 and the side plate are rotated exactly 90 degrees. At this time, the extrusion column 604 is perpendicular to the bottom plate, and the extrusion column 604 is pressed against the top of the bottom plate under the elastic force of the extrusion spring 607, so as to fix the top surface of the bottom plate. At this time, the side plate and the bottom plate are also perpendicular to each other, but there is still a distance of one to two centimeters between the bottom of the side plate and the top of the bottom plate. At this time, the screw rod 2 702 is rotated, and the screw rod 2 702 drives the moving block 706 and the electric telescopic rod 703 to move downward together, that is, drives the side plate to move downward until the bottom of the side plate is in contact with the bottom plate. If there is still a certain distance between the bottom of the side plate and the side plate installation on the bottom plate, it is only necessary to control the electric telescopic rod 703 so that the electric telescopic rod 703 drives the side plate to move horizontally until the bottom of the side plate is aligned with the side plate installation on the bottom plate, and the placement of the side plate can be completed. ;

[0029] Then the connection between the bottom plate and the side plate can be welded, and the transverse motor 905 is started. The transverse motor 905 drives the movable block 904 to move to both ends or the middle. The movable block 904 drives the electric hydraulic cylinder 906, the fixed frame 907 and the frame 909 to move to both ends or the middle. The frame 909 drives the screw rod 4 903, the block 910 and the welding gun 1010 to move to both ends or the middle until the connection between the welding gun 1010 and the bottom plate and the side plate forms a forty-five angle. The transverse motor 905 can be turned off, and the electric hydraulic cylinder 906 is started again. The electric hydraulic cylinder 906 drives the fixed frame 907 and the frame 909 to move to the connection. The frame 909 drives the screw rod 4 903, the block 910 and the welding gun 1010 to move to the connection until the welding gun 1010 moves to a distance from the connection. When the joint is one to two millimeters away, the longitudinal motor 908 is started again, and the longitudinal motor 908 drives the block 910 and the welding gun 1010 to move together until the welding gun 1010 moves to the starting point of the joint, and then the longitudinal motor 908 drives the welding gun 1010 to move to the end point of the joint, and the welding gun 1010 and the reciprocating motor 1002 are started at the same time, the reciprocating motor 1002 drives the driving gear 1006 to rotate, the driving gear 1006 drives the driven gear 1007 and the fan gear 1008 to rotate, the two fan gears 1008 drive the rack 1005 to reciprocate left and right, the rack 1005 drives the connecting block 1009 and the welding gun 1010 to reciprocate left and right, so that the welding gun 1010 can perform Z-shaped automatic welding on the connection between the bottom plate and the side plate.
