They are mainly used to support photovoltaic brackets and solar panels. Generally, the surface of photovoltaic ground piles will be welded with connecting nuts or reinforcement sheets, which can be used as auxiliary components for positioning and installation during the construction process. When the ground piles are driven into the ground or connected to the foundation, the reinforcement sheets can help determine the position and angle of the ground piles, improve the accuracy and efficiency of the construction, and at the same time, the reinforcement sheets can also provide better support and connection points for the subsequent installation of photovoltaic modules, making the installation process more convenient;

[0003] However, the existing welding devices need to use multiple welding guns to weld nuts or reinforcement plates from multiple angles. A large number of sparks will be emitted during welding. These sparks are not only small but also very hot. If they are not avoided in time, they will burn the operators.

[0026] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0027] 1. A welding assembly is provided, and welding is performed gradually and continuously through a welding gun, so a large number of sparks will not be generated at the same time during welding, and no matter where the welding gun moves to, the suction pipe is always in the middle of the top of the object to be welded, so that the suction force can be evenly covered on the top of the entire welding point. At this time, sparks generated at any position will be sucked into the inner side of the recovery box, thereby reducing or even eliminating spark splashes during the photovoltaic pile welding process, which not only protects the operator, but also prevents the splashing sparks from damaging the surface of the photovoltaic pile, improves the antioxidant capacity of the photovoltaic pile, and further prevents the splashing sparks from damaging the welding machine, especially protecting various rubber pipes near the machine, and further ensuring the safety of operation;

[0028] After using it for a period of time, you can pry open the handle on one side of the recycling box to release the adsorption between the connecting magnet and the recycling cover, and then quickly replace the wet sponge inside the recycling box to ensure cooling efficiency. When it is necessary to weld nuts of different sizes, you can unscrew the clamping screw from the threaded barrel on the top of the threaded seat, and then replace the guide rods of different outer diameters, so as to meet the use of nuts of different sizes and improve the convenience of welding.

[0029] When welding irregular-shaped reinforcement sheets, adjust the welding wire in the welding gun to another side for mobile welding. After welding of multiple sides is completed, reset the welding gun. At this time, the welding gun can be used to weld a variety of materials. Not only regular polygonal nuts can be welded, but also irregular polygonal reinforcement sheets can be welded, which increases the application range of the welding device and reduces the space occupied by the welding device, so that it is convenient for operators to deploy multiple machines and further improve work efficiency.

[0030] 2. A clamping assembly is provided. Because the position of the bottom sliding seat is fixed, when welding other steel pipes of the same batch and uniform specifications in the future, it is only necessary to place the steel pipe on the inner side of the supporting groove plate. At this time, the moving clamping seat can push one end of the steel pipe to the side of the contact plate, so that the steel pipes can be moved and fixed at the same welding position, which is convenient for operators to quickly load materials, simplifies the steel pipe fixing steps, and is simple and convenient to operate to improve the efficiency of pile welding manufacturing;

[0031] Turning on the reversing motor can drive the steel pipe to rotate through the clamping plate, and can quickly align the notches of the nuts or reinforcement plates that need to be welded with the top guide rod. If multiple nuts need to be welded, after welding one, the different positions of the outside of the steel pipe can be rotated to the bottom of the guide rod by rotating the reversing motor. The operation is simple and fast, and no manual position adjustment is required, which reduces the chance of contact between the operator and the welding device to prevent burns. The reversing motor can also accurately control the rotation angle to further improve the welding accuracy and the manufacturing quality of the photovoltaic ground piles.

[0032] In summary, the flying sparks in the process of photovoltaic ground pile welding can be reduced or even eliminated, the operators can be protected, the chance of contact between operators and sparks can be reduced, thereby preventing the flying sparks from contacting the operators and preventing the operators from being scalded. When adjusting the position of the steel pipe, the different positions of the outside of the steel pipe can be rotated to the bottom of the guide rod through the reversing motor. The operation is simple and quick, and no manual position adjustment is required, which further reduces the chance of contact between operators and welding equipment and prevents burns, thereby improving the overall work safety of operators.

The steel pipe 321 is clamped on the top of the rotating roller 311.

[0064] According to the above technical solution, a photovoltaic ground pile is a product manufactured according to an automatic welding machine for photovoltaic ground piles.

[0065] The working principle and use process of the present invention are as follows: First, the operator places the steel pipe 321 to be welded into a photovoltaic ground pile on the inner side of the supporting slot plate 309, adjusts the steel pipe 321 to align the notch on its surface with the guide rod 226, and then controls the electric telescopic rod 314 to extend and drive the clamping plate 317 to move, thereby clamping the steel pipe 321 between the clamping plate 317 and the contact plate 307 for fixation;

[0066] At this time, the nut to be welded is sleeved on the outside of the guide rod 226 and adsorbed to the bottom position of the clamping magnetic sheet 225, and then the two hydraulic cylinders 202 are controlled to extend downward, so that the connecting frame 203 can be driven to move to the bottom by the hydraulic cylinder 202. At this time, the clamping tube 204 can be driven to move to the bottom by the connecting frame 203. At this time, the guide rod 226 at the bottom of the clamping tube 204 will drive the nut to move to the notch at the top of the steel pipe 321, and the guide rod 226 will be inserted into the inside of the notch and the nut will be clamped and fixed. At this time, the nut to be welded can be preliminarily fixed, and when it is necessary to weld nuts of different sizes, the clamping screw 224 can be screwed out from the threaded barrel 223 at the top of the threaded seat 222, and then the guide rods 226 of different outer diameters can be replaced, so that nuts of different sizes can be used, thereby improving the convenience of welding.

[0067] After the nut to be welded is initially fixed, the radius fixing screw 213 is loosened and then the position restriction of the radius fixing screw 213 on the sliding rod 212 is released. At this time, the sliding rod 212 can be slid on the inner side of the sliding frame 211, so that the electric slide rail 214, the electric sliding seat 215, the fixing cylinder 216 and the internal welding gun 217 are slid outward to adapt to the size of the nut to be welded. After adjusting to the appropriate position, the radius fixing screw 213 is quickly tightened to fix the position of the welding gun 217, and then the length fixing screw 218 is loosened. Then, the welding gun 217 can be slid on the inner side of the fixing cylinder 216, and the welding wire inside the welding gun 217 is moved to the outside of the nut to be welded, and then the length fixing screw 218 is tightened and fixed, so that subsequent batches of nuts can be conveniently carried out. To weld, after adjusting the position of the welding gun 217, the servo motor 208 inside the motor mounting seat 207 is controlled to start, so that the driving gear 209 can be driven to rotate, and then the driven gear 210 is driven to rotate through the driving gear 209, and the driven gear 210 will drive the rotating cylinder 206 to rotate on the outside of the rotating bearing 205, and then the welding gun 217 can be driven to rotate through the rotating cylinder 206. At this time, the nut can be quickly welded by rotating the welding gun 217. During welding, since most nuts are regular equilateral polygons, the welding wire inside the welding gun 217 will continue to extend and weld with the nut, so that the rotary one-time welding can be completed, and after a circle of welding is completed, the position of the welding gun 217 needs to be rotated and reset to prevent the power cord 219 from being entangled and reset;

[0068] And the ducted fan 236 is started while welding, at this time the ducted fan 236 will generate a huge suction force, at this time the huge suction force will absorb and clean up some debris adsorbed on the surface of the steel pipe 321, so as to prevent the vaporization of these adsorbed debris during welding to form steam bubbles, so as to prevent the high-temperature liquid metal from bursting to form sparks when the steam bubbles burst, and reduce the number of sparks formed. Even if sparks are generated during welding, these sparks will enter the inner side of the suction pipe 220 through the notches on both sides of the fixing rod 221 under the action of the huge suction force, and then the sparks preliminarily cooled by the high-speed flowing air will enter the inside of the arc-shaped connecting pipe 227, and then part of the sparks will fall to the top of the wet sponge 231 inside the recovery box 230 when passing through the bottom of the arc-shaped connecting pipe 227, and will be further cooled to form metal particles, and part of the sparks will be blocked by the metal mesh 235, and will also fall into the inside of the recovery box 230 after the welding is completed;

[0069] At this time, because the welding is performed gradually and continuously by the welding gun 217, a large number of sparks will not be generated at the same time during welding, and no matter where the welding gun 217 moves to, the suction pipe 220 is always in the middle position of the top of the object to be welded, so that the suction force can be evenly covered on the top of the entire welding point. At this time, sparks generated at any position will be sucked into the inner side of the recovery box 230, thereby reducing or even eliminating spark splashes during the photovoltaic pile welding process, not only protecting the operator, but also preventing the splashing sparks from damaging the surface of the photovoltaic pile, improving the antioxidant capacity of the photovoltaic pile, and further preventing the splashing sparks from damaging the welding machine, especially protecting various rubber pipes near the machine, further ensuring the safety of operation, and after using it for a period of time, the handle on one side of the recovery box 230 can be moved to release the adsorption between the connecting magnet 229 and the recovery cover 228, and then the wet sponge 231 inside the recovery box 230 can be quickly replaced to ensure cooling efficiency;

[0070] Next, when welding the irregularly shaped reinforcement sheet, first rotate the welding gun 217 to one corner of the reinforcement sheet through the rotating cylinder 206, and then turn on the electric sliding seat 215. At this time, the electric sliding seat 215 will drive the fixed cylinder 216 and the welding gun 217 to slide on the outside of the electric slide rail 214. At this time, one side of the irregular reinforcement sheet can be quickly welded, and after welding one side, the rotating cylinder 206 can be rotated to adjust the welding wire in the welding gun 217 to another side for mobile welding. After welding of multiple sides is completed, the welding gun 217 is reset. At this time, the welding gun 217 can be used to weld a variety of materials, not only regular polygonal nuts can be welded, but also irregular polygonal reinforcement sheets can be welded, which increases the application range of the welding device and reduces the space occupied by the welding device, so that it is convenient for operators to deploy multiple machines and further improve work efficiency.

[0071] Finally, when welding steel pipes 321 of different lengths, first loosen the limiting screw 305 to move the bottom sliding seat 303 and the stabilizing plate 304 to one end of the positioning track 302, then place the steel pipe 321 on the inner side of the supporting groove plate 309, so that the steel pipe 321 is placed at the top position of the symmetrical support frame 310 and the rotating roller 311. At this time, align the position to be welded with the top guide rod 226, and then slide the bottom sliding seat 303 on the top of the positioning track 302. At this time, the contact plate 307 can be fitted on one end of the steel pipe 321, and then tighten the limiting screw 305 to press against the top of the positioning track 302, so as to fix the bottom sliding seat 303, and then control the electric telescopic rod 314 to extend, which can drive the clamping seat 315 to move on the positioning track 302. The top of the steel pipe 321 can be slid, and then the clamping plate 317 can be pressed against the other end of the steel pipe 321. At this time, the steel pipe 321 can be fixed and clamped. After the welding is completed, the electric telescopic rod 314 can be directly controlled to retract, so that the clamping restriction on the steel pipe 321 can be released. At this time, because the position of the bottom sliding seat 303 is fixed, when welding other steel pipes 321 of the same batch and uniform specifications in the future, it is only necessary to place the steel pipe 321 on the inner side of the supporting groove plate 309. At this time, the mobile clamping seat 315 can push one end of the steel pipe 321 to one side of the contact plate 307, so that the steel pipes 321 can be moved and fixed at the same welding position, which is convenient for operators to quickly load materials, simplifies the fixing steps of the steel pipe 321, and is simple and convenient to operate to improve the efficiency of pile welding manufacturing.

[0072] And after the steel pipe 321 is fixed, if the welded notch is not directly opposite to the bottom of the guide rod 226, the reversing motor 313 can be turned on to drive the transmission block 320 to rotate. Then, since the transmission block 320 is mutually engaged with the transmission rod 316 through the driven groove 319, the clamping plate 317 can be driven to rotate through the transmission block 320. At this time, the steel pipe 321 and the contact plate 307 can be driven to rotate through the clamping plate 317. At this time, the contact plate 307 rotates on the inner side of the bottom sliding seat 303 through the drag reduction bearing 306, and the presence of the limit plate 308 can prevent the contact plate 307 from deviating from the position The steel pipe 321 can be moved at a constant speed at the bottom end of the guide rod 226, and then the notch of the nut or reinforcement plate to be welded can be quickly aligned with the top guide rod 226. If multiple nuts need to be welded, after welding one, the different positions of the outside of the steel pipe 321 can be rotated to the bottom of the guide rod 226 by rotating the reversing motor 313. The operation is simple and fast, and no manual position adjustment is required, which reduces the probability of contact between the operator and the welding device to prevent burns. The reversing motor 313 can be used to accurately control the rotation angle, thereby further improving the welding accuracy and the manufacturing quality of the photovoltaic piles.
