The conveyor belt 1 includes an upstream outer panel welding position and a downstream inner panel welding position. The outer panel receiving box 2 is placed on the conveyor belt 1 to fix the outer perimeter panels of the cabinet. The outer panel welding machine, located at the outer panel welding position, includes an outer panel welding robotic arm 3 and an outer panel welding gun located at the movable end of the robotic arm 3. 4; The outer panel welding position limiter 5 is located at the outer panel welding position and is used to stop the outer panel receiving box 2 at the outer panel welding position or to allow it to continue moving; The inner panel placement machine is located at the inner panel welding position and includes an inner panel placement robotic arm 6 and a gripper located at the movable end of the inner panel placement robotic arm 6; The inner panel welding machine is located at the inner panel welding position and includes an inner panel welding robotic arm 7 and an inner panel welding torch 8 located at the movable end of the inner panel welding robotic arm 7; The inner panel welding position limiter 9 is located at the inner panel welding position and is used to stop the outer panel receiving box 2 at the inner panel welding position or to allow it to continue moving.

[0037] During the welding and assembly process of the multi-storage steel cabinet, the outer panel receiving box 2 is used to fix the outer panel of the cabinet in the assembly position, and is then sequentially conveyed to the upstream outer panel welding position and the downstream inner panel welding position via conveyor belt 1. At the outer panel welding position, such as... Figure 3 As shown, the outer panel receiving box 2 is stopped by the outer panel welding position limiter 5, and the outer panel welding robotic arm 3 moves the outer panel welding gun 4 to the designated welding position on the outer panel and performs welding. Afterwards, the outer panel welding position limiter 5 releases the outer panel receiving box 2, allowing it to be transferred to the inner panel welding position, as shown. Figure 4 As shown, the inner plate is placed to the set position by the inner plate placement robot arm 6, and then the inner plate welding robot arm 7 drives the inner plate welding gun 8 to move to the set welding position of the inner plate and perform welding.

[0038] In some specific embodiments, such as Figure 5 As shown, the outer panel receiving box 2 includes a bottom plate 201, a left side plate 202, a right side plate 203 and a rear side plate 204 disposed on the bottom plate 201, an interlayer disposed in the bottom plate 201, the left side plate 202, the right side plate 203 and the rear side plate 204, an adsorption through hole disposed on the inner side of the left side plate 202, the right side plate 203 and the rear side plate 204 and communicating with the interlayer, and a negative pressure pump communicating with the interlayer;

[0040] In some specific embodiments, the left side panel 202, the right side panel 203, and the rear side panel 204 are all conformal panels to better fit the outer panel of the cabinet and achieve a stable negative pressure adsorption effect.

[0041] In some specific embodiments, the outer plate welding robotic arm 3, the inner plate placement robotic arm 6, and the outer plate welding robotic arm 3 all include a transverse guide rail, a longitudinal guide rail, and a telescopic rod that are orthogonally slidably connected in sequence. Specifically, it includes a support, a transverse guide rail that is parallel to the support and parallel to the conveyor belt 1, a transverse slide block that is slidably disposed on the transverse guide rail, a longitudinal guide rail that is disposed on the transverse slide block and perpendicular to the conveyor belt 1, a longitudinal slide block that is disposed on the longitudinal guide rail, and a telescopic rod that is disposed on the longitudinal slide block. The telescopic rod extends in the direction of the extension and retraction of the telescopic rod towards the conveyor belt 1. Both the transverse and longitudinal slide blocks can move in three dimensions—horizontal, vertical, and transverse—under the action of linear drive components such as linear motors and motor-driven screw and nut mechanisms.

[0042] In some specific embodiments, a rotating motor is also provided between the telescopic rod of the inner plate placement robot arm 6 and the gripping component, which is used to adjust the posture of the gripped inner plate.

[0043] In some specific embodiments, the gripping element is a claw or a vacuum suction cup. The claw grips the inner panel mechanically, while the vacuum suction cup grips the inner panel using negative pressure adsorption.

[0046] In some specific embodiments, the outer panel welding position limiter 5 and the inner panel welding position limiter 9 include a lifting rod disposed between the first conveyor belt and the second conveyor belt, and a blocking block disposed on the lifting rod. The blocking block can rise above the conveyor belt 1 to block the outer panel receiving box 2, or fall below the conveyor belt 1 to release the outer panel receiving box 2.

[0047] In some specific embodiments, the outer panel welding position limiter 5 and the inner panel welding position limiter 9 are proximity sensors electrically connected to the conveyor belt to stop the conveyor belt when the outer panel receiving box 2 is detected to have reached the designated position, and to start the conveyor belt after welding is completed at both stations.

[0048] In some specific embodiments, the automated welding equipment also includes a controller that electrically connects to the conveyor belt 1, the outer panel receiving box 2, the outer panel welding machine, the outer panel welding position limiter 5, the inner panel placement machine, the inner panel welding machine, and the inner panel welding position limiter 9, to perform welding of the outer and inner panels of the cabinet.
