Description

Technical Field

[0001] The present invention relates to the technical field of ground pile welding, and in particular to an automatic welding machine for photovoltaic ground piles and the photovoltaic ground piles. Background Art

[0002] Photovoltaic ground piles are a new type of green energy equipment that combines photovoltaic power generation and ground pile foundations. They are mainly used to support photovoltaic brackets and solar panels. Generally, the surface of photovoltaic ground piles is welded with connecting nuts or reinforcement plates, 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 plates can help determine the position and angle of the ground piles, improving the accuracy and efficiency of construction. At the same time, the reinforcement plates 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 device requires the use of multiple welding guns to weld nuts or reinforcement plates from multiple angles, and a large number of sparks will be ejected during welding. These sparks are not only small but also very hot. If they are not avoided in time, they will burn the operator. In addition, these sparks will splash onto the ground piles or the welding machine, causing damage to the ground piles and the machine, thereby increasing the danger of ground pile welding. In order to avoid the above technical problems, it is indeed necessary to provide an automatic welding machine for photovoltaic ground piles and photovoltaic ground piles to overcome the above-mentioned defects in the prior art.

[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 the 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 weld. At this time, sparks generated at any position will be sucked into the inner side of the recovery box, thereby reducing or even eliminating sparks 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 the 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 you can quickly replace the moist sponge inside the recycling box to ensure cooling efficiency. When you need to weld nuts of different sizes, you can unscrew the tightening screw from the threaded barrel at the top of the threaded seat, and then replace the guide rods with different outer diameters, so that you can meet the use of nuts of different sizes and improve welding convenience.

[0029] When welding irregular-shaped reinforcement plates, adjust the welding wire in the welding gun to another edge for mobile welding. After welding multiple edges, 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 plates. This increases the applicability of the welding device and reduces the space occupied by the welding device, making it easier for operators to deploy multiple machines and further improving work efficiency.

[0030] 2. A clamping assembly is provided. Since the position of the bottom sliding seat is fixed, when welding other steel pipes of the same batch and the same 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 clamping seat can be moved to push one end of the steel pipe to the side of the contact plate, so that the steel pipes can be moved and fixed in 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, improving the efficiency of pile welding manufacturing;

[0031] Turning on the reversing motor can drive the steel pipe to rotate through the clamping disk, 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 reversing motor can be rotated to the different positions on the outside of the steel pipe to the bottom of the guide rod. 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 spark flying during the photovoltaic ground pile welding process is reduced or even eliminated, the operator is protected, and the chance of the operator coming into contact with the sparks is reduced, thereby preventing the ejected sparks from coming into contact with the operator and preventing the operator from being scalded. In addition, when adjusting the position of the steel pipe, the different positions of the outer side 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 does not require manual position adjustment, further reducing the chance of the operator coming into contact with the welding device and preventing burns, thereby improving the overall work safety of the operator.

The top of the rotating roller 311 is engaged with the steel pipe 321.

[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 usage process of the present invention are as follows: First, the operator places the steel pipe 321 to be welded into the photovoltaic ground pile on the inner side of the supporting groove plate 309, adjusts the steel pipe 321 so that the notch on its surface aligns 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 outer side of the guide rod 226 and adsorbed to the bottom position of the clamping magnetic sheet 225. 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. 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. When it is necessary to weld nuts of different sizes, the clamping screw 224 can be unscrewed 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 as to meet the use of nuts of different sizes and improve welding convenience.

[0067] After the nut to be welded is initially fixed, the radius fixing screw 213 is loosened and 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. The welding gun 217 can then 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 perform welding, after adjusting the position of the welding gun 217, the servo motor 208 inside the motor mounting seat 207 is controlled to start, thereby driving the driving gear 209 to rotate, and then the driven gear 210 is driven to rotate through the driving gear 209. 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 continuously extends and continuously adheres to the nut for welding, thereby completing rotary one-time welding. After completing a circle of welding, 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] The ducted fan 236 is started while welding, and at this time, the ducted fan 236 generates a huge suction force, which will absorb and clean some debris adsorbed on the surface of the steel pipe 321, thereby preventing steam bubbles formed by the vaporization of these adsorbed debris during welding, thereby preventing the high-temperature liquid metal from exploding when the steam bubbles burst to form sparks, and reducing 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 that are initially cooled by the high-speed flowing air will enter the interior of the arc-shaped connecting pipe 227. Then, some 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. Another part of the sparks will be blocked by the metal mesh 235 and will also fall into the interior of the recovery box 230 after the welding is completed.

[0069] At this time, because the welding is carried out step by step 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 weld. 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 sparks 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, further ensuring operational safety, and after using 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 moist sponge 231 inside the recovery box 230 can be quickly replaced, thereby ensuring cooling efficiency;

[0070] Next, when welding an irregularly shaped reinforcement sheet, the welding gun 217 is first rotated to one corner of the reinforcement sheet through the rotating cylinder 206, and then the electric sliding seat 215 is turned on. 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 multiple sides, 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 applicability of the welding device and reduces the space occupied by the welding device, thereby facilitating the operator to deploy multiple machines and further improving 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 on the top position of the symmetrical support frame 310 and the rotating roller 311, and 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, and 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, thereby fixing 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 is directly controlled to retract, so that the clamping restriction of 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 the same specification 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 moving 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 in the same welding position, which is convenient for the operator to quickly load the material, simplifies the steps of fixing 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 facing 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 by the transmission block 320. At this time, the steel pipe 321 and the contact plate 307 can be driven to rotate by 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 position of the contact plate 307 from deviating. The steel pipe 321 can be moved at a constant speed at the bottom end of the guide rod 226 at this time, 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 outer side 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 does not require manual position adjustment, which reduces the chance of contact between the operator and the welding device to prevent burns. The reversing motor 313 can also accurately control the rotation angle to further improve the welding accuracy and the manufacturing quality of the photovoltaic ground piles.
