They are typically made of metal materials, such as aluminum alloy or galvanized steel, to ensure corrosion resistance and structural strength. A single photovoltaic rack typically consists of two individual racks and multiple crossbeams. Each rack includes a front leg, a rear leg, and a diagonal beam. Multiple crossbeams are fixedly connected to the two individual racks to form a complete photovoltaic rack. Welding is a common connection technique used in the manufacture of photovoltaic racks. During the welding process, formed and cut metal sheets are assembled and connected using a welding process to ensure a strong and stable rack structure.

DETAILED DESCRIPTION

[0037] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0038] like Figures 1-12 As shown, a welding machine and welding method for photovoltaic bracket processing include two groups of brackets 1, and the brackets 1 are prior art. Each bracket 1 is composed of a front leg 11, a rear leg 12, and an inclined beam 13. Among them, the front leg 11 and the rear leg 12 are both vertically arranged, and the height of the front leg 11 is less than the height of the rear leg 12. The two ends of the inclined beam 13 are fixedly connected to the top of the front leg 11 and the rear leg 12 respectively. A plurality of mutually parallel cross beams 14 need to be welded to the inclined beam 13. In this application, two cross beams 14 are taken as an example.

[0039] The welding machine also includes a processing table 2, two position-limiting assemblies 3, a loading assembly 4, and a welding assembly 5. The processing table 2 primarily serves as a mounting and support structure, providing a mounting and support carrier for the corresponding components. The position-limiting assembly 3 is primarily used to position the bracket 1, ensuring a more secure mounting position and facilitating the welding of the crossbeam 14 to the bracket 1. The loading assembly 4 is used to transport the crossbeams 14 individually to the diagonal beams 13. The welding assembly 5 is primarily used to weld the joints between the crossbeams 14 and the diagonal beams 13.

[0040] Specifically, if Figure 1 、 Figure 3 、 Figure 6 and Figure 12 As shown, the top of the processing table 2 is provided with two mutually parallel limit grooves 21 and a transition plate 22. The two limit grooves 21 correspond one to one with the two brackets 1, and the limit grooves 21 are used to limit the corresponding brackets 1. The length of the limit groove 21 can be equal to the farthest distance between the front leg 11 and the rear leg 12. The transition plate 22 is arranged between the two limit grooves 21, and the top of the transition plate 22 is coplanar with the top of the inclined beam 13. The transition plate 22 is mainly used to support the cross beam 14 during the transportation of the cross beam 14 to prevent the end of the cross beam 14 from tilting downward. It should be noted that a plurality of support legs are fixedly connected to the bottom of the processing table 2 to support the processing table 2. A column is provided at the bottom of the transition plate 22, and the column is fixedly connected to the processing table 2, and the column is used to support the transition plate 22.

[0041] In addition, if Figure 2 、 Figure 4 、 Figure 7 and Figure 12As shown, the two limiting components 3 correspond to the two limiting slots 21 one by one. The limiting component 3 includes: two limiting plates 31 and a power component 32. The power component 32 is used to selectively drive the two limiting plates 31 to move in the limiting slot 21 to contact the front foot 11 and the rear foot 12 respectively.

[0042] Specifically, two mutually parallel installation slots 23 are opened at the bottom of the processing table 2. The two installation slots 23 correspond to the two limiting slots 21 and the two limiting components 3 one by one. The top of the installation slot 23 is connected to the corresponding limiting slot 21.

[0043] The power component 32 includes: a double-headed screw 321, two first nut seats 322 and a first motor 323. It should be noted that the thread directions on both sides of the double-headed screw 321 are opposite. The double-headed screw 321 is arranged in the corresponding installation slot 23, and both ends of the double-headed screw 321 are rotatably connected to two opposite side walls of the installation slot 23 respectively. One end of the double-headed screw 321 extends to the outside of the processing table 2 and is fixedly connected to the output shaft of the first motor 323. The first motor 323 is fixedly connected to the processing table 2. The axial direction of the double-headed screw 321 can be the same as the length direction of the limiting slot 21. The two first nut seats 322 are respectively threadedly connected to both sides of the double-headed screw 321, and the two limiting plates 31 are respectively fixedly connected to the tops of the two first nut seats 322.

[0044] During use, in the initial state, the two limiting plates 31 are close to each other, and the distances between the front foot 11 and the corresponding limiting plate 31 and between the rear foot 12 and the corresponding limiting plate 31 are equal. After the bracket 1 is placed in the limiting slot 21, the sides of the front foot 11 away from the rear foot 12 and the sides of the rear foot 12 away from the front foot 11 can respectively contact the two opposite side walls of the limiting slot 21. At this time, start the first motor 323. The first motor 323 will drive the double-headed screw 321 to rotate. The rotation of the double-headed screw 321 can drive the two first nut seats 322 to move away from each other, thereby driving the two limiting plates 31 to move away from each other until the two limiting plates 31 respectively contact the corresponding front foot 11 and rear foot 12, so as to realize the limiting and fixing of the bracket 1. After the bracket 1 is welded to the cross beam 14, reverse the rotation of the first motor 323 to release the limit on the bracket 1.

[0045] As an optional embodiment, as Figure 3 shown, in the vertical direction, the cross-sectional shape of the top of the limiting plate 31 is a U-shaped structure, and the opening directions of the two limiting plates 31 are opposite. It should be noted that the top of the limiting plate 31 extends to the outside of the limiting slot 21. The top of the limiting plate 31 is set as a U-shaped structure, and the opening size of the U-shaped structure can be the same as the width sizes of the corresponding front foot 11 and rear foot 12. In this way, the side walls of the front foot 11 and the rear foot 12 can be clamped by the U-shaped structure, so that the setting of the bracket 1 is more stable and reliable.

[0046] In addition, if Figure 1 、 Figure 4 and Figures 6-11 As shown, the loading assembly 4 includes: a loading plate 41, an L-shaped material transport rod 42, a feeding assembly 43 and a driving assembly 44. The loading plate 41 includes: a horizontal plate 412 and an inclined plate 411 parallel to the inclined beam 13. Among them, the upper side of the inclined plate 411 is fixedly connected to one side of the horizontal plate 412. The L-shaped material transport rod 42 is arranged above the inclined plate 411, and the L-shaped material transport rod 42 includes: a horizontal rod 421 and an inclined rod 422 parallel to the inclined beam 13. The L-shaped material transport rod 42 selectively moves on the surface of the inclined plate 411 to transport the crossbeam 14 on the inclined plate 411 to different positions on the inclined beam 13. The feeding assembly 43 is used to drop the crossbeam 14 on the horizontal plate 412 onto the horizontal rod 421. The driving assembly 44 is used to provide power for the movement of the L-shaped material transport rod 42. It should be noted that the cross beams 14 on the horizontal plate 412 are all arranged parallel to the horizontal rods 421 , so that the cross beams 14 can better slide along the surface of the inclined plate 411 to the horizontal rods 421 .

[0047] Specifically, the inclined plate 411 is arranged close to any limiting slot 21, and the limiting slot 21 to which the inclined plate 411 is close is located between the other limiting slot 21 and the inclined plate 411. A movable hole 4111 is provided on the inclined plate 411, and the movable hole 4111 includes: a movable hole 1 4112 parallel to the inclined beam 13 and a plurality of movable holes 2 4113 perpendicular to the inclined beam 13. The plurality of movable holes 2 4113 are parallel to each other, and the plurality of movable holes 2 4113 are spaced apart along the inclined direction of the inclined plate 411. The ends of the plurality of movable holes 2 4113 away from the limiting slot 21 are all connected to the movable hole 1 4112. It should be noted that the number of movable holes 2 4113 and the distance between adjacent movable holes 2 4113 can be set according to the number of beams 14 and the distance between adjacent beams 14. In the present application, the number of movable holes 2 4113 can be set to two.

[0048] Furthermore, the drive assembly 44 can be positioned below the inclined plate 411 to reduce interference between the drive assembly 44 and the L-shaped material transport rod 42 and the crossbeam 14. The drive assembly 44 includes a horizontal drive assembly 441 and an inclined drive assembly 442. The horizontal drive assembly 441 is used to drive the L-shaped material transport rod 42 along the length of the second moving hole 4113. The inclined drive assembly 442 is used to drive the L-shaped material transport rod 42 along the length of the first moving hole 4112.

[0049] Specifically, the horizontal drive assembly 441 includes a mounting base 4411, a screw rod 4412, a nut seat 4413, and a motor 4414. The mounting base 4411 is connected to the tilt drive assembly 442. A mounting hole 4415 is defined within the mounting base 4411 along the length of the second movable hole 4113. The screw rod 4412 is disposed within the mounting hole 4415, and its two ends are rotatably connected to two opposing inner walls of the mounting hole 4415. The axis of the screw rod 4412 is aligned with the length of the second movable hole 4113. One end of the screw rod 4412 extends outside the mounting base 4411 and is fixedly connected to the motor 4414. The motor 4414 is fixedly connected to the outer wall of the mounting base 4411. The nut seat 4413 is threadedly connected to the screw rod 4412 and passes through the movable hole 4111 to be fixedly connected to the L-shaped material transport rod 42. It should be noted that in order to smoothly transport the crossbeam 14 to the inclined beam 13, the inclined rod 422 can be positioned on the side of the horizontal rod 421 away from the inclined beam 13. This allows the inclined rod 422 to provide power to the crossbeam 14 and to limit the position of the crossbeam 14 during transportation. Furthermore, the second nut seat 4413 can be fixedly connected to the connection between the horizontal rod 421 and the inclined rod 422. It should be noted that the length of the horizontal rod 421 can be greater than or equal to the length of the crossbeam 14, and the length of the inclined rod 422 can be set according to actual working conditions.

[0050] The tilt drive assembly 442 includes: a mounting plate 1 4421, a mounting plate 2 4422, a nut seat 3 4423, a screw 2 4424, and a motor 3 4425. The mounting plate 1 4421 and the mounting plate 2 4422 are fixedly connected to the upper and lower sides of the tilt plate 411, respectively. The nut seat 3 4423 is fixedly connected to the bottom of the mounting seat 4411. The two ends of the screw 2 4424 are fixedly connected to the mounting plate 1 4421 and the mounting plate 2 4422, respectively. The nut seat 3 4423 is threadedly connected to the screw 2 4424. One end of the screw 2 4424 extends to the outside of the mounting plate 2 4422 and is fixedly connected to the motor 3 4425. The motor 3 4425 is fixedly connected to the tilt plate 411. It should be noted that the axial direction of the screw 2 4424 is the same as the length direction of the inclined beam 13.

[0051] During use, in the initial state, nut seat 2 4413 is located at the connection between moving hole 1 4112 and moving hole 2 4113. When the crossbeam 14 falls onto the horizontal rod 421, motor 2 4414 is started, which drives screw rod 1 4412 to rotate. The rotation of screw rod 1 4412 is transmitted through nut seat 2 4413, driving the L-shaped material transport rod 42 to move toward the side of the inclined beam 13, thereby driving the crossbeam 14 to move toward the side of the inclined beam 13. The end of the crossbeam 14 away from the inclined rod 422 moves successively through the adjacent inclined beam 13 and transition plate 22 to the more distant inclined beam 13. When the two ends of the crossbeam 14 are in contact with both inclined beams 13, the welding assembly 5 is started to weld the connection between the crossbeam 14 and the upper side of the inclined beam 13. After the upper side welding is completed, motor 2 4414 is started to retract the L-shaped material transport rod 42 to its initial state. Then, welding assembly 5 is used to weld the connection between horizontal beam 14 and the lower side of inclined beam 13. After welding is completed, motor 3 4425 is started, which drives screw 2 4424 to rotate. The rotation of screw 2 4424 is transmitted through nut seat 3 4423, which drives mounting seat 4411 to move along the axial direction of the screw, thereby driving L-shaped material transport rod 42 to move upward along the axial direction of the screw. During the movement of L-shaped material transport rod 42, nut seat 2 4413 moves along movable hole 1 4112. When nut seat 2 4413 moves to the connection between movable hole 2 4113 and movable hole 1 4112 on the upper side, motor 3 4425 is stopped. At this time, the feeding assembly 43 is started to drop a crossbeam 14 onto the inclined plate 411. The crossbeam 14 will slide along the inclined surface of the inclined plate 411 and onto the horizontal rod 421. Then, the second motor 4414 is started, which drives the first screw 4412 to rotate. The rotation of the first screw 4412 is transmitted through the second nut seat 4413 to drive the L-shaped material transport rod 42 to move toward the side of the inclined beam 13, thereby driving the crossbeam 14 to move toward the side of the inclined beam 13. The end of the crossbeam 14 away from the inclined rod 422 moves successively through the adjacent inclined beam 13 and the transition plate 22 to the more distant inclined beam 13. When the two ends of the crossbeam 14 are in contact with both inclined beams 13, the welding assembly 5 is started to weld the connection between the crossbeam 14 and the upper side of the inclined beam 13. After the upper side welding is completed, start the second motor 4414 to retract the L-shaped material transport rod 42 to the initial state, and then use the welding assembly 5 to weld the connection between the lower side of the cross beam 14 and the inclined beam 13.

[0052] In this way, the entire welding process is completed, and then a new bracket 1 is replaced and the above steps are repeated.

[0053] As an optional embodiment, Figure 4 、 Figure 6 and Figure 7As shown, the welding machine also includes a mounting plate 3 6, a mounting plate 4 7, a guide plate 8, and a guide rod 9. The mounting plate 3 6 and the mounting plate 4 7 are respectively fixedly connected to the bottom of the upper and lower sides of the inclined plate 411. The guide plate 8 is fixedly connected to the bottom of the mounting seat 4411. The guide rod 9 slides through the guide plate 8, and the two ends of the guide rod 9 are respectively fixedly connected to the mounting plate 3 6 and the mounting plate 4 7. The axis of the guide rod 9 is parallel to the axis of the screw 2 4424. When the mounting seat 4411 moves along the axial direction of the screw 2 4424, the guidance and support of the guide rod 9 can make the movement of the mounting seat 4411 more stable.

[0054] In addition, if Figure 4 and Figure 8 As shown, the feeding assembly 43 includes: a cylinder 431 and two parallel baffles 432. The cylinder 431 is set on the horizontal plate 412, and the extension direction of the cylinder 431 and the length direction of the two baffles 432 are perpendicular to the length direction of the movable hole 4113. The cylinder 431 is used to push the crossbeam 14 between the two baffles 432 onto the inclined plate 411 in sequence and contact the horizontal rod 421. It should be noted that when the crossbeam 14 is placed, the length direction of the crossbeam 14 is set perpendicular to the extension direction of the cylinder 431, and multiple crossbeams 14 can be placed together in parallel, but should not be stacked. The extension end of the cylinder 431 can contact the middle position of the crossbeam 14, and the distance between the two baffles 432 is equal to the length of the crossbeam 14. This can better push the crossbeam 14 parallel to the horizontal rod 421. It should be noted that the height setting of the baffle 432 is set according to the actual working conditions so as not to affect the movement of the inclined rod 422.

[0055] During use, after adjusting the position of the horizontal rod 421, it is necessary to push the crossbeam 14 on the horizontal plate 412 onto the horizontal rod 421. At this time, the cylinder 431 is activated, and the cylinder 431 pushes the adjacent crossbeam 14 toward the inclined plate 411. During the movement, when a crossbeam 14 away from the cylinder 431 falls onto the inclined plate 411, the cylinder 431 is stopped, and the crossbeam 14 that has fallen onto the inclined plate 411 will slide onto the horizontal rod 421, and then be transported to the inclined beam 13 by the L-shaped material transport rod 42.

[0056] In addition, if Figure 1 、 Figure 2 、 Figure 4-Figure 6 and Figure 8 As shown, the welding assembly 5 includes a welding gun 51 and a position adjustment assembly 52. ​​In the initial state, the muzzle of the welding gun 51 is set downward. The position adjustment assembly 52 is used to adjust the spatial position of the welding gun 51.

[0057] Specifically, the position adjustment assembly 52 includes: a mounting frame 521, a cross module 522 and a hydraulic cylinder 523. The mounting frame 521 is fixedly connected to the processing table 2. The mounting frame 521 includes an annular support frame 5211 and multiple support plates 5212. The bottom of the support plate 5212 is fixedly connected to the processing table 2, and the top of the support plate 5212 is fixedly connected to the support frame 5211. The cross module 522 is a prior art. The cross module 522 is fixedly connected to the mounting frame 521. Specifically, the cross module 522 is fixedly connected to the support frame 5211. The cross module 522 is used to adjust the position of the welding gun 51 in the horizontal direction. The fixed end of the hydraulic cylinder 523 is fixedly connected to the slider on the cross module 522, and the telescopic end of the hydraulic cylinder 523 is connected to the welding gun 51. The hydraulic cylinder 523 is used to adjust the position of the welding gun 51 in the vertical direction.

[0058] When the cross beam 14 is transported to the inclined beam 13, the welding gun 51 can be moved to the connection between the cross beam 14 and the inclined beam 13 using the cross module 522 and the hydraulic cylinder 523, so that the welding gun 51 can be started to weld the connection.

[0059] In addition, if Figure 4 and Figure 5 As shown, the welding assembly 5 also includes an angle adjustment assembly 53. The angle adjustment assembly 53 is used to adjust the inclination angle between the welding gun 51 and the horizontal plane, thereby more accurately aligning the muzzle of the welding gun 51 with the junction of the horizontal beam 14 and the inclined beam 13. The angle adjustment assembly 53 includes a connecting base 531, a connecting block 532, a clamping plate 533, and a motor 534. The connecting base 531 can be an L-shaped structure, comprising a horizontal portion 5311 and a vertical portion 5312. The horizontal portion 5311 of the connecting base 531 is fixedly connected to the telescopic end of the hydraulic cylinder 523. The motor 534 is fixedly connected to the vertical portion 5312 of the connecting base 531, and the output shaft of the motor 534 passes through the vertical portion 5312 and is fixedly connected to the connecting block 532. The clamping plate 533 is fixedly connected to the connecting block 532 and is used to securely connect the welding gun 51 to the connecting block 532. The axis of the output shaft of motor four 534 is arranged parallel to the beam 14.

[0060] When in use, start motor four 534, which will drive the connecting block 532 to rotate, and then drive the welding gun 51 to rotate through the clamping plate 533, and then adjust the angle of the muzzle of the welding gun 51, so that the connection between the cross beam 14 and the inclined beam 13 can be welded more accurately.

[0061] For example, when the crossbeam 14 is placed on two inclined beams 13, it is necessary to weld the upper and lower connections of the crossbeam 14 and the inclined beam 13 respectively. Since the horizontal rod 421 is located at the lower side of the crossbeam 14, the connection between the crossbeam 14 and the upper side of the inclined beam 13 is welded first. At this time, the angle of the welding gun 51 is adjusted so that the gun muzzle is facing the angle between the crossbeam 14 and the upper side of the inclined beam 13 for welding.

[0062] A welding method for a welding machine used for processing a photovoltaic bracket 1, comprising the following steps:

[0063] Step 1: First, place the two brackets 1 in parallel in the corresponding limiting grooves 21;

[0064] Step 2: Use the driving assembly 44 to adjust the L-shaped material transport rod 42 to the lowermost moving hole 2 4113;

[0065] Step 3: Start the feeding assembly 43 to push the beam 14 between the two baffles 432, so that the beam 14 closest to the inclined plate 411 falls onto the inclined plate 411 and slides onto the horizontal rod 421;

[0066] Step 4: Use the driving assembly 44 to drive the L-shaped material transport rod 42 to move horizontally to push the crossbeam 14 onto the two inclined beams 13;

[0067] Step 5: Start the welding assembly 5 and use the welding assembly 5 to weld the connection between the cross beam 14 and the inclined beam 13;

[0068] Step 6: Start the driving assembly 44 to retract the L-shaped material transport rod 42, move it upward, and adjust it to the second moving hole 4113 at the lower position, and repeat steps 3 to 5.

The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
