Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to a high-efficiency welding device for processing photovoltaic brackets. Background Art

[0002] Photovoltaic bracket, also known as solar photovoltaic bracket, is a special bracket designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. It is generally made of aluminum alloy, carbon steel and stainless steel. It is mainly composed of vertical rods and horizontal rods used to support the entire bracket, as well as steel sections (such as angle steel, square steel pipes, etc.) used to support solar panels. When making a photovoltaic bracket, the steel sections need to be welded and fixed to the horizontal rods.

[0039] The welding assembly 3 includes a moving mechanism 31. Two moving mechanisms 31 are symmetrically provided on the sides of the mounting plate 30. A welding mechanism 32 is provided at the lower end of each moving mechanism 31. The moving mechanism 31 is used to drive the welding mechanism 32 to move and weld. The two welding mechanisms 32 can weld the sides of the photovoltaic bracket simultaneously.

[0040] The welding mechanism 32 includes an adjusting plate 320, and a welding head 321 is provided on the side of the adjusting plate 320 away from the moving mechanism 31. A discharge head 322 is provided in the adjusting plate 320, and the discharge head 322 is a hollow structure.

A first roller 325 is rotatably provided in the adjusting plate 320, and a second bevel gear 326 is provided on the upper end of the first roller 325. The first bevel gear 324 and the second bevel gear 326 are meshed with each other. A second roller 327 is also provided in the adjusting plate 320.

[0041] Another embodiment provided by the present invention further includes a mounting assembly 2, the mounting assembly 2 including a fixed plate 20, the fixed plate 20 being in a ∩ shape, a mounting plate 30 being rotatably provided at one end of the lower side of the fixed plate 20, a first worm gear 21 being fixedly provided at the upper end of the mounting plate 30, the central axis of the first worm gear 21 coinciding with the rotation center of the mounting plate 30 on the fixed plate 20, a rotating shaft 22 being rotatably provided at the middle portion of the fixed plate 20, two worms 23 being provided on the rotating shaft 22, the first worm gear 21 being meshed with one of the worms 23 on the rotating shaft 22;

[0042] The specific implementation is as follows: before welding the photovoltaic bracket, according to the welding angle between the photovoltaics to be welded, the rotating shaft 22 is rotated so that the rotating shaft 22 drives the worm 23 provided thereon to rotate, so that the rotating shaft 22 drives the first worm wheel 21 meshing with it to rotate through the worm wheel 23, so that the first worm wheel 21 fixedly set in the middle of the upper end of the mounting plate 30 drives the mounting plate 30 to rotate, so that the rotating shaft 22 adjusts the angle of the mounting plate 30 through the first worm wheel 21 and the first worm wheel 23, so that the mounting plate 30 adjusts the moving direction of the moving mechanism 31, and ensures that the moving mechanism 31 drives the welding mechanism 32 to move the connection of the welded photovoltaic bracket; and the worm gear structure has self-locking properties, so that the angle of the mounting plate 30 after adjustment will not change during the welding process.

[0043] In another embodiment provided by the present invention, a loading assembly 4 is further included, wherein the loading assembly 4 includes a loading plate 40, a screw rod 41 is provided in a rotatable manner in the loading plate 40, one end of the screw rod 41 is connected to the output end of the loading motor 42 through a coupling, the loading motor 42 is provided at the lower end of the loading plate 40, an extrusion block 43 is provided on the outside of the screw rod 41 by threaded fitting, a slide groove is provided on the loading plate 40, a guide rod 430 is provided in the slide groove, the extrusion block 43 is provided in the slide groove in a sliding manner, and the extrusion block 43 is slidably sleeved on the outside of the guide rod 430, a second worm gear 44 is fixedly provided on the upper side of one end of the loading plate 40 close to the telescopic rod 1, and the second worm gear 44 is meshed with the other worm 23 of the rotating shaft 22;

[0044] The specific implementation is as follows: a sensor is provided on the loading plate 40, which drives another worm 23 to rotate through the rotating shaft, so that the worm 23 drives the second worm gear 44 meshed with it to rotate, so that the rotating shaft drives the loading plate 40 to rotate and tilt through the worm 23 and the second worm gear 44, so that the loading plate 40 can rotate synchronously with the mounting plate 30, so that the loading plate 40 and the mounting plate 30 are synchronously tilted on the fixing plate 20 and the tilt angle is the same; before welding the photovoltaic bracket, multiple square steel pipes to be welded are placed in the loading plate 40, so that the loading plate 40 can store the square steel pipes to be welded. During welding, the feeding motor 42 rotates, causing the feeding motor 42 to drive the screw rod 41 to rotate, thereby causing the screw rod 41 to drive the extrusion block 43 to move through threaded cooperation. When the extrusion block 43 moves, the slide groove and the guide rod 430 can guide and limit the extrusion block 43, thereby causing the extrusion block 43 to squeeze the square steel pipe located in the feeding plate 40, so that the square steel pipes are loaded one by one, so that the square steel pipes are placed in the welding position. After the square steel pipes are placed in the welding position, the sensor detects it and controls the feeding motor 42 to stop rotating, so that the welding head 321 can weld the square steel pipes to the photovoltaic bracket.

[0045] Another embodiment provided by the present invention further includes a support assembly 5, which includes two sliding blocks 50 symmetrically and slidably arranged on the side of the mounting plate 30 away from the loading assembly 4, each of the sliding blocks 50 is provided with a connecting plate 51 at one end away from the mounting plate 30, and each of the connecting plates 51 is provided with a threaded barrel 52 at the lower end of the side away from the mounting plate 30, each of the threaded barrels 52 is provided with a threaded rod 53 in a threaded fit manner, and each of the threaded rods 53 is provided with a retaining ring 54 in a rotatable manner at one end away from the threaded barrel 52, and a reinforcing plate 55 is provided between the threaded barrel 52 and the connecting plate 51;

[0046] The specific implementation is as follows: a connecting spring 503 is provided between the two sliding blocks 50. Before the photovoltaic bracket is welded, the threaded rod 53 is rotated to make the threaded rod 53 move along the length direction of the threaded barrel 52, so that the threaded rod 53 adjusts the total length between the threaded rod 53 and the threaded barrel 52, thereby making the threaded rod 53 drive the retaining ring 54 to move, so that the retaining ring 54 can support and limit the lower end of the square steel pipe of different lengths placed in the welding position, thereby preventing the square steel pipe from slipping during the welding process and causing welding failure; and according to the width of the square steel pipe, the connecting plate 51 can drive the sliding block 50 to move along the side of the mounting plate 30, so that the connecting plate 51 can clamp and fix the side of the square steel pipe, and at the same time, the two sliding blocks 50 and the two connecting plates 51 are pulled closer to each other by the connecting spring, thereby strengthening the clamping of the connecting plate 51 on the side of the square steel pipe; in addition, the connection and fixation between the threaded barrel 52 and the connecting plate 51 is strengthened by the reinforcing plate 55, thereby preventing the threaded barrel 52 and the threaded rod 53 from bending and deformation when supporting and limiting the square steel pipe.

[0047] In another embodiment provided by the present invention, each of the sliding blocks 50 is provided with a clamping block 500 at one end thereof facing the interior of the mounting plate 30 in a sliding manner. A clamping spring 501 is provided between the clamping block 500 and the sliding block 50. The end of the clamping block 500 away from the connecting plate 51 and the end of the mounting plate 30 closer to the clamping block 500 are both rough surfaces.

[0048] The specific implementation is as follows: during the movement of the sliding block 50, in order to avoid vibration and other reasons causing the sliding block 50 to move and making it difficult for the connecting plate 51 to support and limit the square steel pipe, when the connecting spring approaches and fits the surface of the square steel pipe through the connecting plate 51, the threaded tube 52 and the threaded rod 53 can support and limit the lower end of the square steel pipe through the retaining ring 54. At the same time, the clamping spring 501 squeezes the clamping block 500 so that the clamping block 500 is tightly attached to the inner side of the mounting plate 30, and the end of the clamping block 500 facing the mounting plate and the end of the mounting plate 30 close to the clamping block 500 are both rough surfaces. The clamping spring 501 squeezes the clamping block 500 to approach and fit the rough surface of the mounting plate 30, making it difficult for the clamping block 500 and the mounting plate 30 to slide against each other, thereby making the clamping block 500 cooperate with the connecting spring to strengthen the limiting support of the square steel pipe.

[0049] Furthermore, a groove is provided at the lower end of the loading plate 40, a notch is provided on one side of the groove, and a slope is provided on one side of the notch. Specifically, when multiple square steel pipes to be welded are placed in the loading plate 40, the groove is used to limit and support the lower ends of the multiple square steel pipes to be welded, so that the loading plate 40 can limit and store the multiple square steel pipes to be welded. After the square steel pipes are limited and stored in the loading plate 40, the loading motor 42 is rotated, so that the loading motor 42 drives the screw rod 41 to rotate, so that the screw rod 41 drives the extrusion block 43 to move through the threaded cooperation, and then the extrusion block 43 squeezes the square steel pipe located in the loading plate 40, so that the square steel pipe moves along the groove toward the notch, so that the square steel pipes fall from the notch one by one, and at the same time cooperates with the threaded rod 53 and the threaded cylinder 52 after adjustment, so that the retaining ring 54 cooperates with the notch to load the fallen square steel pipes one by one, and the slope at the notch facilitates the loading of the square steel pipes from the notch.

[0050] In another embodiment provided by the present invention, the moving mechanism 31 includes two moving blocks 310, both of which are slidably arranged on the sides of the mounting plate 30. A moving plate 311 is commonly mounted on the two moving blocks 310. A driving motor 312 is disposed inside the moving plate 311, and a driving gear 313 is disposed at the output end of the driving motor 312. A rack 314 is further disposed on the side of the mounting plate 30 where the sliding block 50 is disposed, and the driving gear 313 is meshed with the rack 314.

[0051] The specific implementation is as follows: during welding, after the square steel pipe is placed in the welding position, the driving motor 312 drives the driving gear 313 to rotate, so that the driving gear 313 engages and moves along the rack 314. When the driving gear 313 moves along the rack 314, it drives the driving motor 312, the moving plate 311 and the moving block 310 to move along the mounting plate 30, so that the moving plate 311 drives the adjustment plate 320 to move, so that the moving plate 311 drives the discharge head 322 and the welding head 321 to move, so that the discharge head 322 and the welding head 321 weld the square steel pipe to the photovoltaic bracket when moving; and by controlling the rotation speed of the driving motor 312, the welding speed of the welding head 321 can be adjusted to ensure the welding quality.

[0052] In another embodiment provided by the present invention, the moving mechanism 31 further includes an electric push rod 315, which is disposed at the lower end of the moving plate 311. An adjustment plate 320 is disposed at the protruding end of the electric push rod 315. One end of two guide rods 316 are symmetrically disposed on one side of the adjustment plate 320 close to the moving plate 311. The other end of the guide rod 316 is slidably disposed within the moving plate 311.

[0053] The specific implementation is as follows: after the square steel pipe is placed in the welding position, the electric push rod 315 is first used to drive the adjustment plate 320 to move toward the welding position of the square steel pipe, so that the discharge head 322 and the welding head 321 are close to the welding position of the square steel pipe. After the welding is completed, the electric push rod 315 drives the adjustment plate 320 to move in the opposite direction, so that the discharge head 322 and the welding head 321 move away from the square steel pipe, so that the welding mechanism 32 is away from the welding position, which facilitates the welding equipment to be away from the welded square steel pipe and facilitates the movement of the welding equipment; and when the adjustment plate 320 moves, the guide rod 316 is used to guide and limit the moving adjustment plate 320 to prevent the electric push rod 315 from driving the adjustment plate 320 to rotate.

[0054] In another embodiment provided by the present invention, the welding mechanism 32 further includes two sliding blocks 328 . The two sliding blocks 328 are slidably disposed within the adjustment plate 320 , and a sliding block 328 is rotatably disposed at each end of the second roller 327 . A return spring 329 is disposed between each sliding block 328 and the adjustment plate 320 .

[0055] The specific implementation is as follows: during welding, the first bevel gear 324 is driven to rotate by the conveying motor 323, so that the first bevel gear 324 drives the first roller 325 to rotate through the second bevel gear 326, so that the first roller 325 and the second roller 327 convey the welding wire clamped therebetween to the discharge head 322, so that the discharge head 322 places the welding wire at the gap between the square steel pipe and the photovoltaic, that is, the welding position, so that the welding head 321 welds the welding position, and the welding wire conveyed to the welding position by the first roller 325 and the second roller 327 is melted to enhance the welding effect; at the same time, in order to adapt to different diameters After the welding wires of different diameters are inserted between the first roller 325 and the second roller 327, the sliding block 328 is adjusted to slide in the adjustment plate 320 by the return spring 329, so that the sliding block 328 drives the second roller 327 to move and is at different distances from the first roller 325, so that the distance between the first roller 325 and the second roller 327 can adapt to welding wires of different diameters, ensuring that the first roller 325 and the second roller 327 can always clamp welding wires of different diameters, so that the first roller 325 and the second roller 327 can stably transport the welding wire, thereby ensuring the welding effect of the welding head 321.

[0056] Furthermore, an angle plate is provided on the lower side of the movable plate 311, and a locking rod is slidably provided in the middle of the angle plate, and the upper end of the locking rod is provided at the lower end of the movable plate 311 by threaded engagement. Specifically, the locking rod is rotated so that the upper end of the locking rod is disengaged from the movable plate 311. At this time, the locking rod is pulled outward from the angle plate and the disc-shaped welding wire is placed on the inner side of the angle plate. After the welding wire is placed, the locking rod is rotated in the opposite direction so that the locking rod locks the disc-shaped welding wire to the inner side of the angle plate. At the same time, the free end of the disc-shaped welding wire passes through the adjustment plate 320, and passes between the first roller 325 and the second roller 327, and finally passes out from the discharge head 322. In this way, the conveying motor 323 drives the first roller 325 to rotate through the first bevel gear 324 and the second bevel gear 326, so that the first roller 325 and the second roller 327 convey the welding wire to the discharge head 322, so that the welding wire can strengthen the welding of the photovoltaic bracket at the welding head 321 during welding.

[0057] In another embodiment provided by the present invention, the welding mechanism 32 further includes a limiting plate 3210, which is provided on the outer side of the discharge head 322. Both sides of the limiting plate 3210 are connected to the discharge head 322 via limiting rods 3211, and a steel ball is rotatably provided on the side of the limiting plate 3210 close to the photovoltaic bracket.

[0058] The specific implementation is as follows: the efficient welding equipment for photovoltaic bracket processing is installed on the mobile device through the telescopic rod 1. This is the existing technology and will not be described in detail. When the electric push rod 315 drives the welding head 321 and the discharge head 322 to approach the welding position through the adjustment plate 320, in order to prevent the adjustment plate 320 from driving the welding head 321 and the discharge head 322 to directly hit the square steel pipe, a limit plate 3210 is set on the discharge head 322. The limit plate 3210 can first contact the square steel through the steel ball. Tube, when the adjusting plate 320 drives the discharge head 322 and the welding head 321 to move and weld the square steel pipe, the discharge head 322 is limited and protected by the limiting plate 3210, and the limiting plate 3210 is supported by the limiting rod 3211 to prevent the discharge head 322 and the welding head 321 from touching or even colliding with the square steel pipe after the limiting plate 3210 is deformed. The steel balls facilitate the adjustment plate 320 to drive the welding head 321 and the discharge head 322 to move along the welding position of the square steel pipe.

[0059] Working principle: Before welding the photovoltaic bracket, according to the welding angle between the photovoltaics to be welded, the rotating shaft 22 is rotated so that the rotating shaft 22 drives the worm 23 provided thereon to rotate, so that the rotating shaft 22 drives the first worm gear 21 meshed with it to rotate through the worm gear 23, so that the first worm gear 21 fixedly provided at the middle of the upper end of the mounting plate 30 drives the mounting plate 30 to rotate, so that the rotating shaft 22 adjusts the angle of the mounting plate 30 through the first worm gear 21 and the first worm gear 23, so that the mounting plate 30 adjusts the moving direction of the moving mechanism 31, ensuring that the moving mechanism 31 drives the welding mechanism 32 to move the connection of the photovoltaic bracket for welding; and the worm gear structure has self-locking properties, so that the angle of the mounting plate 30 will not change after the adjustment is completed during the welding process;

[0060] A sensor is provided on the loading plate 40, which drives another worm 23 to rotate through the rotating shaft, so that the worm 23 drives the second worm gear 44 meshed with it to rotate, so that the rotating shaft drives the loading plate 40 to rotate and tilt through the worm 23 and the second worm gear 44, so that the loading plate 40 can rotate synchronously with the mounting plate 30, so that the loading plate 40 and the mounting plate 30 are synchronously tilted on the fixing plate 20 and the tilt angle is the same; before welding the photovoltaic bracket, multiple square steel pipes to be welded are placed in the loading plate 40, so that the loading plate 40 can treat The welded square steel pipes are stored. During welding, the feeding motor 42 rotates, causing the feeding motor 42 to drive the screw rod 41 to rotate, so that the screw rod 41 drives the extrusion block 43 to move through the threaded fit, and then the extrusion block 43 squeezes the square steel pipes located in the feeding plate 40, so that the square steel pipes are fed one by one, so that the square steel pipes are placed in the welding position. After the square steel pipes are placed in the welding position, the sensor detects that the feeding motor 42 stops rotating, which facilitates the welding head 321 to weld the square steel pipes to the photovoltaic bracket.

[0061] By rotating the threaded rod 53, the threaded rod 53 moves along the length direction of the threaded cylinder 52, so that the threaded rod 53 adjusts the total length between the threaded rod 53 and the threaded cylinder 52, thereby making the threaded rod 53 drive the retaining ring 54 to move, so that the retaining ring 54 can support and limit the lower end of the square steel pipe of different lengths placed in the welding position, thereby preventing the square steel pipe from slipping and causing welding failure during the welding process; and according to the width of the square steel pipe, the connecting plate 51 can drive the sliding block 50 to move along the side of the mounting plate 30, so that the connecting plate 51 can clamp and fix the side of the square steel pipe, and at the same time, the two sliding blocks 50 and the two connecting plates 51 are pulled closer to each other by the connecting spring, thereby strengthening the clamping of the connecting plate 51 to the side of the square steel pipe; during the movement of the sliding block 50, in order to avoid vibration and other reasons causing the sliding block 50 to move and causing the connecting plate 51 to be difficult to meet the square steel pipe When the clamping plate 501 is pressed against the clamping block 500, the clamping block 500 is pressed against the inner side of the mounting plate 30, and the end of the clamping block 500 facing the mounting plate 30 and the end of the mounting plate 30 close to the clamping block 500 are both rough surfaces. The clamping spring 501 presses the clamping block 500 toward the rough surface of the mounting plate 30 and fits it, making it difficult for the clamping block 500 and the mounting plate 30 to slide against each other, thereby making it difficult for the clamping block 500 to cooperate with the connecting spring to strengthen the limiting support of the square steel pipe; in addition, the reinforcing plate 55 strengthens the connection and fixation between the threaded barrel 52 and the connecting plate 51, thereby preventing the threaded barrel 52 and the threaded rod 53 from bending and deforming when supporting and limiting the square steel pipe;

[0062] When the locking cam 321 is unlocked, the locking cam 322 is unlocked and the locking cam 323 is unlocked, so that the locking cam 322 is unlocked and the locking cam 323 is unlocked.

[0063] The lower end of the loading plate 40 is provided with a groove, one side of the groove is provided with a notch, and one side of the notch is provided with an inclined surface. Specifically, when multiple square steel pipes to be welded are placed in the loading plate 40, the lower ends of the multiple square steel pipes to be welded are limited and supported by the groove, so that the loading plate 40 can limit and store the multiple square steel pipes to be welded. After the square steel pipes are limited and stored in the loading plate 40, the loading motor 42 rotates, so that the loading motor 42 drives the screw rod 41 to rotate, so that the screw rod 41 drives the extrusion block 43 to move through the threaded engagement, and then the extrusion block 43 squeezes the square steel pipe located in the loading plate 40, so that the square steel pipe moves along the groove toward the notch, so that the square steel pipe falls from the notch one by one, and at the same time cooperates with the threaded rod 53 and the threaded cylinder 52 after adjustment, so that the retaining ring 54 cooperates with the notch to load the fallen square steel pipes one by one, and the inclined surface at the notch facilitates the loading of the square steel pipe from the notch;

[0064] During welding, after the square steel pipe is placed in the welding position, the driving motor 312 drives the driving gear 313 to rotate, so that the driving gear 313 engages and moves along the rack 314. When the driving gear 313 moves along the rack 314, it drives the driving motor 312, the moving plate 311 and the moving block 310 to move along the mounting plate 30, so that the moving plate 311 drives the adjusting plate 320 to move, so that the moving plate 311 drives the discharge head 322 and the welding head 321 to move, so that the discharge head 322 and the welding head 321 weld the square steel pipe to the photovoltaic bracket when moving, and the speed of the welding head 321 can be adjusted by controlling the rotation speed of the driving motor 312. After the welding is completed, the electric push rod 315 drives the adjusting plate 320 to move in the opposite direction, so that the discharging head 322 and the welding head 321 are moved away from the square steel pipe, so that the welding mechanism 32 is away from the welding position, which facilitates the welding equipment to be away from the welded square steel pipe and facilitates the movement of the welding equipment. When the adjusting plate 320 moves, the guide rod 316 is used to control the moving adjusting plate 320. The guide limit prevents the electric push rod 315 from rotating when driving the adjustment plate 320 to move; the conveying motor 323 drives the first bevel gear 324 to rotate, so that the first bevel gear 324 drives the first roller 325 to rotate through the second bevel gear 326, so that the first roller 325 and the second roller 327 convey the welding wire clamped therebetween to the discharge head 322, so that the discharge head 322 places the welding wire at the welding position between the square steel pipe and the photovoltaic, so that the welding head 321 welds the welding position, and the welding wire conveyed to the welding position by the first roller 325 and the second roller 327 is melted to enhance the welding effect; at the same time To accommodate welding wires of different diameters, after welding wires of different diameters are inserted between the first roller 325 and the second roller 327, the return spring 329 is used to adjust the sliding block 328 to slide within the adjustment plate 320, so that the sliding block 328 drives the second roller 327 to move and to be at different distances from the first roller 325. This ensures that the distance between the first roller 325 and the second roller 327 can adapt to welding wires of different diameters, ensuring that the first roller 325 and the second roller 327 can always clamp welding wires of different diameters, so that the first roller 325 and the second roller 327 can stably transport the welding wire, thereby ensuring the welding effect of the welding head 321;At the same time, when the electric push rod 315 drives the welding head 321 and the discharge head 322 to approach the welding position through the adjustment plate 320, in order to prevent the adjustment plate 320 from driving the welding head 321 and the discharge head 322 to directly hit the square steel pipe, a limit plate 3210 is set on the discharge head 322. The limit plate 3210 can first contact the square steel pipe through the steel ball. In this way, when the adjustment plate 320 drives the discharge head 322 and the welding head 321 to move and weld the square steel pipe, the discharge head 322 is limited by the limit plate 3210. The limiting rod 3211 supports the limiting plate 3210 to prevent deformation of the limiting plate 3210, which could cause the discharge head 322 and the welding head 321 to touch or even hit the square steel pipe. The steel ball facilitates the adjustment plate 320 to drive the welding head 321 and the discharge head 322 to move along the welding position of the square steel pipe. When the square steel pipes are loaded one by one and placed at the welding position, the telescopic rod 1 is driven by an external device to move, thereby driving the welding equipment to move, so that the welding equipment can weld the square steel pipes to the photovoltaic bracket one by one.
