[0002] With the growth of demand for clean energy at home and abroad, the market demand for photovoltaic power generation equipment is increasing, and the application scenarios of photovoltaic power generation are also increasing. As a support component buried underground in photovoltaic power generation, photovoltaic ground pile is specially used to fix the photovoltaic module support in the solar photovoltaic power generation system, which can evenly transfer the weight of the photovoltaic module and its support to the ground, ensuring that the entire photovoltaic power generation system remains stable under various weather conditions and prevents safety accidents such as tilting and collapse.

[0003] At the position close to the end of the photovoltaic ground pile, multiple nuts are usually welded. The design of welding nuts allows the installer to simply screw the bolts into the already welded nuts, quickly fixing the photovoltaic panel, simplifying the installation steps, reducing the installation time, and thus reducing the overall construction cost. In addition, the nut and the photovoltaic ground pile pipe form a whole after welding, effectively enhancing the stability of the photovoltaic ground pile, ensuring the safe operation of the photovoltaic system, and also providing great convenience for later maintenance.

[0004] Currently, the welding of three nuts on the photovoltaic ground pile is carried out by ring welding. Workers manually position the holes on the photovoltaic ground pile pipe for welding nuts on the positioning protrusions of the welding equipment, then manually place the nuts, and then control the welding equipment to automatically ring weld. After welding the three nuts in turn, the workers manually unload and stack them. When using the above production process, the workers need to continuously place the nuts and also need to rotate the photovoltaic ground pile pipe, which is labor-intensive, low in production efficiency, and high in labor cost.

[0005] To solve the above problems, the Chinese invention patent document with authorization publication number CN102699514B discloses a nut automatic welding equipment for spiral ground pile production, which includes multiple high-frequency welding machines and matching nut (i.e. nut) conveying devices arranged side by side. A machine frame B is provided on the feeding side of the multiple high-frequency welding machines, and multiple feeding mechanical hands, multiple welding mechanical hands, a feeding device, and a discharging device are provided on the machine frame B. The multiple feeding mechanical hands and the multiple welding mechanical hands are one-to-one corresponding to the multiple high-frequency welding machines. The multiple welding mechanical hands are provided on one side of the machine frame B close to the high-frequency welding machines, and the multiple feeding mechanical hands are provided on the opposite side. The photovoltaic ground pile pipe is placed on the feeding table by the conveying device, the feeding mechanical hand clamps and positions the photovoltaic ground pile pipe and sends it to the position of the high-frequency welding machine, the nut conveying device sends the nut to the position of the hole on the photovoltaic ground pile pipe, and the welding mechanical hand performs the welding operation.

[0006] The nut automatic welding equipment for the production of spiral piles can realize automatic welding of nuts on the photovoltaic pile pipe, and solves the problems of high labor intensity, low work efficiency and high labor cost caused by manual placement of nuts and rotation of the pipe material;However, since the nut automatic welding equipment for the production of spiral piles is arranged before the automatic forming equipment, the automatic drilling equipment and the automatic sheet penetrating equipment, after the nut welding is completed, the subsequent processes such as the forming of the pointed cone are carried out, which may cause collision and damage to the welded nut during the processing, resulting in problems such as deformation of the nut or loosening of the welding point, and affecting the overall quality of the photovoltaic pile.

[0069] The screw cap welding unit 4 is a prior art, comprising a semi-automatic welding device.

[0070] The working process of the photovoltaic ground pile screw cap welding device is as follows:

[0071] The ground pile pipe 5 to be welded slides along the support 112 to the buffer station, the feeding and lifting cylinder 121 lifts the ground pile pipe 5 to make it fall on the alignment station, the feeding and alignment cylinder 131 retracts to make the screw cap end of the ground pile pipe 5 align with the baffle 113, and after alignment, the feeding and alignment cylinder 131 extends, the feeding and lifting mechanism 14 acts to lift the aligned ground pile pipe 5 and make it slide onto the rolling support plate 331 and slide to the positioning stop surface 3313. At this time, the first and second pushing cylinders 36 and 37 act to make the first and second positioning members 31 and 32 respectively position and clamp the ground pile pipe 5. The first and second servo motors 341 and 351 drive the ground pile pipe 5 to rotate, in the process, the sensor 38 detects the welding hole position on the ground pile pipe, and after the sensor 38 detects the signal, the ground pile pipe is continuously rotated by 180 degrees to make the detected hole be at the uppermost position. At this time, the screw cap feeding mechanism 24 transfers the screw cap 6 sent by the screw cap positioning mechanism 23 to the positioned welding hole position. Then the semi-automatic welding device presses down the screw cap 6, the screw cap feeding mechanism 24 retreats, the semi-automatic welding device starts to weld the screw cap 6, and after the welding is completed, the ground pile pipe 5 is rotated by 120 degrees, and then the screw cap feeding mechanism 24 continues to feed the screw cap 6 for welding. When the welding of the screw cap 6 on the ground pile pipe 5 is completed, the ground pile pipe 5 is lifted and sent away by the rolling and pushing member 332 in the rolling assembly.

[0072] The utility model can perform screw cap welding operation on the photovoltaic ground pile pipe with drilled holes and formed sharp cones, ensure the overall quality of the photovoltaic ground pile, and has high automation degree.
