When the welding motor 408 rotates forward or reverse, the driving screw 409 drives the movable welding seat 401 and the laser welding head 402 to move automatically, thereby realizing the automatic welding of the distribution cabinet parts; when the movable control frame 404 moves to the center position of two semicircular protrusions 101, the corresponding two semicircular protrusions 101 push the movable control frame 404 to move upward, so that the movable control frame 404 automatically presses the control button 406; when the movable control frame 404 is separated from the corresponding two semicircular protrusions 101, the movable control frame 404 is in The laser welding head 402 automatically resets downward under the action of its own gravity and two supporting springs 407; when the control button 406 is in a pressed state, the control box 200 controls the laser welding head 402 to work, ensuring the same spacing between welding points and improving welding accuracy; after welding is completed, the staff starts the switching motor 509 through the control panel 604, so that the tooling support frame 503 automatically rotates 180 degrees under the action of the switching gear 508 and the driving gear 510, realizing the automatic switching of the tooling support frame 503, which is convenient for the operator to remove the parts of the distribution cabinet after welding, and also convenient for the operator to pre-install the parts of the distribution cabinet to be welded, reducing downtime and improving welding efficiency; when the tooling support frame 503 is switched, the air is inhaled The bottom end of the tube 300 and another circular suction hole 5051 are hollow, ensuring that during welding, only a row of suction elbows 506 on the rear side have the suction function; at the same time, the protective baffle 504 has a shielding and protective effect, which shields the smoke generated during welding, so that the welding smoke will not drift forward, thereby ensuring the absorption effect of the welding smoke; after the device is used, the operator can rotate the L-shaped mounting frame 602 in the opposite direction by about ninety degrees, reducing the space occupied by the device, which is beneficial for cleaning personnel to clean the floor of the workshop. At the same time, the two circular conductive heads 610 are automatically separated from the two circular conductive rings 606 under the action of the reset spring 612, ensuring that the operator is always in a relatively safe area when operating the device, reducing safety hazards.
