When the welding operations of the four joints of the four photovoltaic panel frames are all completed, at this time, directly use the controller 104 to activate the two groups of electric valves 215 at the same time. At this time, all four suction cup assemblies 212 will lower the corresponding photovoltaic panel frames with the cooperation of the corresponding hoses 216, the corresponding three-way pipes 214, and the corresponding two activated electric valves 215. Subsequently, use the controller 104 to turn off the two groups of electric valves 215. Then use the controller 104 to activate the four second electric push rods 210 at the same time. At this time, all four activated second electric push rods 210 will, with the cooperation of the corresponding mounting frames 211,Drive the corresponding suction cup assembly 212 to move vertically upward. When each suction cup assembly 212 is separated from the corresponding photovoltaic panel frame, directly use the controller 104 to simultaneously start the four first electric push rods 201. At this time, the four started first electric push rods 201 will, with the cooperation of the corresponding L-shaped plates 202, make the corresponding suction cup assemblies 212 perform reset movement. When the four suction cup assemblies 212 are all reset to their original positions, directly use the controller 104 to simultaneously close the four first electric push rods 201. Then, with the cooperation of tools, remove the photovoltaic panel frame that has completed the welding operation. Next, perform operations according to the above operation steps to perform welding operations on the remaining photovoltaic panel frames.

[0028] Among them, the suction cup assembly 212 consists of: Air collecting shell: The air collecting shell is connected to the hose 216.

[0029] Connecting pipes: Two connecting pipes connect the air collecting shell with the two suction cups respectively.

[0030] Support frame: The support frame mainly plays the role of supporting and fixing the air collecting shell and the suction cups.

[0031] Suction cup: When negative pressure is formed in the air collecting shell and transmitted to the suction cup through the connecting pipe, the air inside the suction cup is pumped out, making the pressure inside the suction cup lower than the external atmospheric pressure, and the suction cup will tightly adsorb the object.

[0032] Among them, the welding mainframe 103 is a laser welding mainframe, the welding torch 109 is a laser welding torch. The welding mainframe 103 is the source of laser energy. It converts electrical energy into a high-energy laser beam through an internal laser generator, and then transmits the laser beam to the welding torch 109. The welding mainframe 103 can precisely control various parameters of the laser. The staff sets the corresponding parameters on the welding mainframe 103 according to factors such as the material and thickness of the photovoltaic panel frame. The welding torch 109 outputs laser for welding according to the parameters set by the welding mainframe 103. Before welding, the staff will plan the movement trajectory for the robotic arm 102 according to the shape and weld position of the photovoltaic panel frame. The movement trajectory of the robotic arm 102 determines the welding path of the welding torch 109. The control cooperation between the welding mainframe 103 and the robotic arm 102 ensures that the robotic arm 102 moves at a predetermined speed and path, and at the same time, the welding mainframe 103 outputs laser for welding at the appropriate position and time.

[0033] Among them, the controller 104 (PLC controller), robotic arm 102, welding mainframe 103, servo motor 107, welding torch 109, first electric push rod 201, drive motor 206, second electric push rod 210, air pump 213, and electric valve 215 are all existing technologies, and their working principles are all publicly known technologies. Their models can be selected according to the actual situation and will not be explained in detail here.
