[0002] The photovoltaic equipment industry exists as a supporting industry for the photovoltaic industry. As the world's largest producer of solar cells, the development of the solar cell industry in my country has driven the overall rise of the photovoltaic industry, which in turn has given rise to my country's photovoltaic equipment industry. With rich technical experience in the field of semiconductor equipment manufacturing, Chinese companies quickly achieved breakthroughs in the field of photovoltaic equipment. Photovoltaic equipment includes multiple solar cells (monocrystalline silicon, polycrystalline silicon or thin-film cells) packaged in series or parallel, with external glass, backplane and aluminum frame protection structures. The supporting components are called photovoltaic brackets, which are used to adjust the optimal tilt angle.

In the existing welding technology process, the workpiece is generally placed directly on the workbench without additional equipment to limit and fix it. The welding work between the two workpieces is carried out solely based on the experience of the staff.

[0013] A welding method for photovoltaic equipment, the specific welding operation method is as follows: S1. The staff puts one end of the photovoltaic support against the top of the photovoltaic welding panel, and then starts the motor on the wide panel frame to drive the screw to rotate, thereby driving the two slides and the outer and inner clamping plates to move in opposite directions. During the process of the two slides moving in opposite directions, the guide rods will guide them horizontally until the two inner clamping plates fit and clamp the outer wall of the photovoltaic support. S2. When the slide plate is driven to move horizontally, the rectangular slot plate and the welding gun are also driven to move horizontally synchronously. When the inner clamp plate contacts the photovoltaic pillar, the elastic member installed between the inner clamp plate and the outer clamp plate, as well as a telescopic plate of the T-shaped clamp plate, can delay the welding gun during the continuous transmission of the screw rod, so that the welding gun and the inner clamp plate can be flush at a specific time position, so that the slide plate and the welding gun move uniformly to contact the photovoltaic pillar. When the welding gun contacts the connection point between the photovoltaic pillar and the photovoltaic welding panel, welding is performed; S3. The process of passive movement of the rectangular slot plate will also push the bracket and a square slot plate to translate. After a square slot plate is passively pushed, it will drive the hinge plate to move tilted, thereby driving the other square slot plate to be horizontally guided on the cross bar, so that the two square slot plates translate in opposite directions to each other, thereby driving multiple arc blocks on each rotating rod to contact the surface of the photovoltaic pillar, thereby causing the torsion spring to deform and at the same time to come into contact with the corresponding abutment plate, thereby generating friction with the surfaces at both ends of the photovoltaic pillar, thereby driving the photovoltaic pillar to rotate at a certain angle. After the motor rotates in the opposite direction, the multiple groups of arc blocks inside it will no longer generate abutting friction with the photovoltaic pillar, and will be automatically reset by the torsion spring, and will no longer drive the photovoltaic pillar to rotate during reset.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) In the present invention, a worker places one end of the photovoltaic support against the top of the photovoltaic welding panel, and then starts the motor on the wide panel frame, so that the motor drives the screw composed of two sections of opposite threaded rods to rotate, thereby driving the two slide plates and the outer clamping plate and the inner clamping plate to move in opposite paths to each other, thereby achieving the outer wall of the photovoltaic support to be fitted and clamped, and the automatic mechanical structure is used to limit and fix it, thereby ensuring the stability of the welding operation; (2) The present invention also pushes the bracket and a square slot plate to translate during the process of passively moving the rectangular slot plate, thereby indirectly driving the hinge plate to tilt and move, so that the two square slot plates translate in opposite directions to each other, so that multiple arc blocks can contact the surface of the photovoltaic pillar, and at the same time, the torsion spring can be deformed and at the same time, it can come into contact with the corresponding abutment plate, thereby generating friction with the surfaces at both ends of the photovoltaic pillar, driving the photovoltaic pillar to rotate at a certain angle, and when the motor rotates in the opposite direction, the multiple groups of arc blocks inside it will no longer generate a compressive friction with the photovoltaic pillar, and will be automatically reset by the torsion spring, thereby no longer driving the photovoltaic pillar to rotate during the reset.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 7 As shown, the present invention provides a welding device for photovoltaic equipment, including a machine base 1, four baffles 11 are fixedly connected to the top inner wall of the machine base 1, a movable plate 12 is slidably connected to the plate bodies of the four baffles 11, two springs 13 are fixedly connected to the plate bodies on both sides of the bottom end of the movable plate 12, the bottom ends of the two groups of springs 13 are fixedly connected to the top inner wall of the machine base 1, two clamping blocks 14 are fixedly connected to the outer walls at both ends of the movable plate 12, and two groups of clamping grooves 15 that can be intermittently clamped with the two clamping blocks 14 are opened in the inner walls at both ends of the machine base 1, a plurality of photovoltaic welding plates 16 are jointly connected to the top of the movable plate 12 and the inner walls of the four baffles 11, and a photovoltaic pillar 17 can be intermittently and tightly fitted on the outer wall of the top of each photovoltaic welding plate 16; A limiting welding part 2 is provided on the machine base 1, and the limiting welding part 2 includes a wide plate frame 21 and a narrow plate frame 22 which are respectively fixedly connected to the two sides of the top of the machine base 1. A motor 23 of a forward and reverse rotating model is fixedly connected to the outer wall of one end of the wide plate frame 21, and a screw rod 24 is fixedly connected to the rotating shaft of the motor, and a clamping structure is provided on the screw rod 24. A friction rotating structure is also provided on the machine base 1.

[0019] The above scheme is adopted: when a photovoltaic welding plate 16 and a photovoltaic support 17 are welded, the finished photovoltaic support is separated from the machine base 1, and the movable plate 12 is no longer pressed, a part of the pressure borne by the multiple springs 13 will automatically drive other photovoltaic welding plates 16 to move up and replenish materials on the multiple baffles 11, and in the process of the movable plate 12 moving up, in order to ensure stability, it will be connected to the card slot 15 in real time through the multiple card blocks 14, so as to achieve automatic material replenishment and support effects; It is worth mentioning that the card block 14 is also made of natural rubber material, so when it is passively moved up, it can be passively moved up and connected into the upper card slot 15 under the action of passive force, and the spring 13 is specially set, and its own elastic expansion force will be proportional to the force it receives, thereby achieving the reduction of a photovoltaic welding panel 16, which will automatically drive the card block 14 to move up one grid through its own elastic force.

[0020] The clamping structure includes a guide rod 25 fixedly connected between the two wide plate frames 21, and slide plates 26 are slidably connected to the rod bodies on both sides of the guide rod 25. One side plate body of the two slide plates 26 is also threadedly connected to the two sides of the rod body of the screw rod 24, and the screw rod 24 is specifically composed of two sections of threaded rod bodies in opposite directions. An outer clamping plate 27 is fixedly connected to one end plate body of the two slide plates 26, and two T-shaped grooves 28 are opened in the inner walls of the two outer clamping plates 27. T-shaped clamping plates 231 are fit and clamped in the two T-shaped grooves 28, and two groups of elastic members 29 are fixedly connected to the inner wall of the outer clamping plate 27. The other ends of the two groups of elastic members 29 are jointly fit and connected with an inner clamping plate 230. The outer wall of the inner clamping plate 230 is fixedly connected to the inner wall of one end of the two T-shaped clamping plates 231, and a section of the plate body connecting the two T-shaped clamping plates 231 and the inner clamping plate 230 is specifically a telescopic plate.

[0021] The above scheme is adopted: start the motor 23 on the wide plate frame 21, so that it operates to drive the screw 24 to rotate, thereby driving the two slides 26 and the outer clamping plate 27 and the inner clamping plate 230 to move in opposite paths to each other, and in the process of the two slides 26 moving in opposite directions, they will be horizontally guided by the guide rod 25 until the two inner clamping plates 230 fit and clamp the outer wall of the photovoltaic pillar 17. Subsequently, when the photovoltaic pillar 17 rotates passively, the two tightly connected inner clamping plates 230 and the two T-shaped clamping plates 231 will rotate in the corresponding T-shaped grooves 28.

[0022] A rectangular groove plate is also threadedly connected to the rod body on one side of the screw rod 24, and a welding gun 232 is fixedly connected to one end of the rectangular groove plate. The muzzle of the welding gun 232 can be intermittently fitted and connected to the connection between the photovoltaic welding plate 16 and the photovoltaic support 17. The rectangular groove plate is also slidably connected to the rod body on one side of the guide rod 25. A support rod 234 is slidably connected to the plate body on the side of the slide plate 26 away from the screw rod 24, and the rod bodies on both sides of the support rod 234 are respectively fixedly connected to the two narrow plate frames 22.

[0023] The above scheme is adopted: when the slide plate 26 is driven to translate, the rectangular groove plate and the welding gun 232 will also be driven to translate synchronously. When the inner clamp plate 230 contacts the photovoltaic pillar 17, the elastic member 29 installed between the inner clamp plate 230 and the outer clamp plate 27, and a telescopic plate of the T-shaped clamp plate 231 can delay the welding gun 232 during the continuous transmission of the screw 24, so that the welding gun 232 and the inner clamp plate 230 can be flush at a specific time position, so that the slide plate 26 and the welding gun 232 move uniformly to contact the photovoltaic pillar 17. When the welding gun 232 contacts the connection point between the photovoltaic pillar 17 and the photovoltaic welding panel 16, a laser beam will be automatically emitted to weld the two.

[0024] The friction rotation structure includes a support plate 237 fixedly connected to a plate body on one side of the top of the machine base 1, a vertical rod 238 fixedly connected to the plate body on one side of the top of the support plate 237, a hinge plate 239 movably sleeved on the vertical rod 238, and square groove plates 240 are hingedly connected to both ends of the hinge plate 239, a bracket 236 is fixedly connected to the outer wall of one square groove plate 240, and the other end of the bracket 236 is fixedly connected to the outer wall of the bottom end of the rectangular groove plate, and a plate 241 is fixedly connected to the outer wall of the other square groove plate 240, and a cross bar 242 is slidably connected to the plate 241, and the cross bar 242 is hinged to the outer wall of the cross bar 242. The rod body at one end is fixedly connected to the plate body of a narrow plate frame 22, and multiple abutment plates 243 are fixedly connected to the inner walls of the two square groove plates 240 and multiple rotating rods 244 are rotatably connected. The rod body of each rotating rod 244 is fixedly connected to multiple arc blocks 245 in a vertical array, and the outer wall of one end of each arc block 245 and the outer wall of the photovoltaic support 17 can be intermittently fitted and slidably connected. A torsion spring 246 is fixedly connected to the rod body near the upper and lower ends of each rotating rod 244, and the other end of each torsion spring 246 is fixedly connected to the upper and lower inner walls of the square groove plate 240 respectively.

[0025] The above scheme is adopted: when the rectangular slot plate is passively moved, it will also push the bracket 236 and a square slot plate 240 to translate. After one square slot plate 240 is passively pushed, it will drive the hinge plate 239 to tilt and move, thereby driving the other square slot plate 240 to be horizontally guided on the cross bar 242, so that the two square slot plates 240 are translated in opposite directions to each other, thereby driving the multiple arc blocks 245 on each rotating rod 244 to contact the surface of the photovoltaic pillar 17, thereby causing the torsion spring 246 to deform and at the same time to contact the corresponding abutment plate 243, thereby generating friction with the surfaces of both ends of the photovoltaic pillar 17, thereby driving the photovoltaic pillar 17 to rotate at a certain angle. After the motor 23 rotates in the opposite direction, the multiple groups of arc blocks 245 inside it will no longer generate abutting friction with the photovoltaic pillar 17, and will be automatically driven to reset by the torsion spring 246, thereby no longer driving the photovoltaic pillar 17 to rotate during reset.

[0026] A welding method for photovoltaic equipment, the specific welding operation method is as follows: S1. The staff puts one end of the photovoltaic support 17 against the top of the photovoltaic welding plate 16, and then starts the motor 23 on the wide plate frame 21 to drive the screw 24 to rotate, thereby driving the two slides 26 and the outer clamping plate 27 and the inner clamping plate 230 to move in opposite paths to each other, and in the process of the two slides 26 moving in opposite directions, the guide rod 25 will guide them horizontally until the two inner clamping plates 230 fit and clamp the outer wall of the photovoltaic support 17; S2. When the slide plate 26 is driven to translate, the rectangular slot plate and the welding gun 232 are also driven to translate synchronously. When the inner clamp plate 230 contacts the photovoltaic pillar 17, the elastic member 29 installed between the inner clamp plate 230 and the outer clamp plate 27, and a telescopic plate of the T-shaped clamp plate 231 can delay the welding gun 232 during the continuous transmission of the screw 24, so that the welding gun 232 and the inner clamp plate 230 can be flush at a specific time position, so that the slide plate 26 and the welding gun 232 move uniformly to contact the photovoltaic pillar 17, and when the welding gun 232 contacts the connection point between the photovoltaic pillar 17 and the photovoltaic welding plate 16, welding is performed; S3. The process of passively moving the rectangular slot plate will also push the bracket 236 and a square slot plate 240 to translate. After a square slot plate 240 is passively pushed, it will drive the hinge plate 239 to tilt, thereby driving the other square slot plate 240 to be horizontally guided on the cross bar 242, so that the two square slot plates 240 translate in opposite directions to each other, thereby driving the multiple arc blocks 245 on each rotating rod 244 to contact the surface of the photovoltaic pillar 17, thereby causing the torsion spring 246 to deform and at the same time produce friction with the corresponding abutment plate 243, thereby generating friction with the surfaces of both ends of the photovoltaic pillar 17, thereby driving the photovoltaic pillar 17 to rotate at a certain angle. After the motor 23 rotates in the opposite direction, the multiple groups of arc blocks 245 inside it will no longer generate a pressing friction force with the photovoltaic pillar 17, and will be automatically reset by the torsion spring 246. When resetting, it will no longer drive the photovoltaic pillar 17 to rotate.

[0027] One point that needs to be added is that one end of the arc block 245 that contacts the surface of the photovoltaic support 17 and drives it to rotate is specifically made of natural rubber material, while the other parts are all made of metal material, which can make the reverse translation generated when the square groove plate 240 is passively reset, and can no longer drive the arc block 245 to generate friction on the surface of the photovoltaic support 17; like Figure 7 As shown, when the square groove plate 240 is passively moved to the right, the natural rubber material portion at one end of the arc block 245 will come into contact with the outer wall of the photovoltaic pillar 17, and at this time, the existence of the abutment plate 243 will exert a pressure and barrier force on the end of the abutment plate 243 that moves to the right, so that the arc block 245 can have enough force to generate friction on the outer wall of the photovoltaic pillar 17, thereby driving the photovoltaic pillar 17 to perform intermittent unidirectional rotation, and realizing intermittent spot welding between the photovoltaic pillar 17 and the photovoltaic welding plate 16 in coordination with the reciprocating movement of the welding gun 232, until the two are fully rotated one circle and welded firmly, and the welding operation is completed.

[0028] The working principle and use process of the present invention are as follows: the staff puts one end of the photovoltaic support 17 against the top of the photovoltaic welding plate 16, and then starts the motor 23 on the wide plate frame 21, so that it operates to drive the screw 24 to rotate, thereby driving the two slide plates 26 and the outer clamping plate 27 and the inner clamping plate 230 to move in opposite paths to each other, and in the process of the two slide plates 26 moving in opposite directions, the guide rod 25 will guide them horizontally until the two inner clamping plates 230 fit and clamp the outer wall of the photovoltaic support 17; in the subsequent process, when the photovoltaic support 17 is passively rotated by the friction rotation structure, the two tightly connected inner clamping plates 230 and the two T-shaped clamping plates 231 will rotate in the corresponding T-shaped grooves 28; When the middle slide plate 26 is driven to translate, the rectangular slot plate and the welding gun 232 are also driven to translate synchronously. When the inner clamping plate 230 contacts the photovoltaic pillar 17, the elastic member 29 installed between the inner clamping plate 230 and the outer clamping plate 27, and a section of the telescopic plate body of the T-shaped clamping plate 231 can delay the welding gun 232 during the continuous transmission of the screw 24, so that the welding gun 232 and the inner clamping plate 230 can be flush at a specific time position. The subsequent rotation of the inner clamping plate 230 will continue to maintain the tight squeezing of the elastic member 29, so that it is compressed to the tightest degree, so that it will not be driven to rotate together when the inner clamping plate 230 rotates. The slide plate 26 and the welding gun 232 move uniformly to contact the photovoltaic pillar 17. When the welding gun 232 contacts the connection point between the photovoltaic pillar 17 and the photovoltaic welding plate 16, it will automatically perform spot welding on it, thereby automatically limiting and fixing the photovoltaic pillar 17, and automatically performing spot welding on it, which greatly reduces manual participation. At the same time, when the rectangular slot plate is passively moved, it will also push the bracket 236 and a square slot plate 240 to translate. After a square slot plate 240 is passively pushed, it will drive the hinge plate 239 to tilt and move with the vertical rod 238 on the support plate 237 as the axis, thereby driving the other square slot plate 240 to translate. The plate 241 on the other square slot plate 240 will be horizontally guided on the cross bar 242, so that the two square slot plates 240 translate in opposite directions to each other, thereby driving the multiple arc blocks 245 on each rotating rod 244 to contact the photovoltaic pillar 1 7; thereby, the torsion spring 246 is deformed, and at the same time, it comes into contact with the corresponding abutment plate 243, thereby generating friction with the surfaces at both ends of the photovoltaic pillar 17, thereby driving the photovoltaic pillar 17 to rotate at a certain angle. After the motor 23 rotates in the opposite direction, it will indirectly drive the welding gun 232 to reset a certain distance. At this time, the square groove plate 240 is indirectly driven to reset, and the multiple groups of arc blocks 245 rotate into the interior of the square groove plate 240. There will be no more friction with the photovoltaic pillar 17, and it will be automatically driven to reset by the torsion spring 246, so that the photovoltaic pillar 17 will no longer be driven to rotate during the reset; When a photovoltaic welding plate 16 and a photovoltaic pillar 17 are welded, the finished photovoltaic bracket is separated from the machine base 1, and thus the movable plate 12 is no longer under pressure, a part of the pressure borne by the multiple springs 13 will automatically drive other photovoltaic welding plates 16 on the multiple baffles 11 to move up to replenish materials, and during the upward movement of the movable plate 12, in order to ensure stability, it will be connected to the card slot 15 in real time through the multiple card blocks 14, thereby realizing automatic material replenishment and support effects.

10. A photovoltaic device welding method, applied to a photovoltaic device welding device as claimed in claim 9, characterized in that: The specific welding operation method is as follows: S1. A worker places one end of the photovoltaic support (17) against the top of the photovoltaic welding plate (16), and then starts the motor (23) on the wide plate frame (21) to drive the screw (24) to rotate, thereby driving the two slide plates (26) and the outer clamping plate (27) and the inner clamping plate (230) to move in opposite directions. During the process of the two slide plates (26) moving in opposite directions, the guide rod (25) guides them horizontally until the two inner clamping plates (230) are in close contact with the outer wall of the photovoltaic support (17); S2, when the slide plate (26) is driven to translate, the rectangular slot plate and the welding gun (232) are also driven to translate synchronously. When the inner clamping plate (230) contacts the photovoltaic pillar (17), the elastic member (29) installed between the inner clamping plate (230) and the outer clamping plate (27), and a telescopic plate of the T-shaped clamping plate (231) can delay the welding gun (232) during the continuous transmission of the screw rod (24), so that the welding gun (232) and the inner clamping plate (230) can be flush at a specific time position, so that the slide plate (26) and the welding gun (232) are uniformly moved to contact the photovoltaic pillar (17), and when the welding gun (232) contacts the connection point between the photovoltaic pillar (17) and the photovoltaic welding plate (16), welding is performed; S3. The process of passively moving the rectangular slot plate will also push the bracket (236) and a square slot plate (240) to move horizontally. After a square slot plate (240) is passively pushed, it will drive the hinge plate (239) to move tilted, thereby driving the other square slot plate (240) to be horizontally guided on the cross bar (242), thereby causing the two square slot plates (240) to move in opposite directions to each other, thereby driving the multiple arc blocks (245) on each rotating rod (244) to contact the photovoltaic The surface of the support (17) causes the torsion spring (246) to deform and, at the same time, to come into contact with the corresponding abutment plate (243), thereby generating friction with the surfaces at both ends of the photovoltaic support (17), thereby driving the photovoltaic support (17) to rotate at a certain angle. After the motor (23) rotates in the opposite direction, the multiple groups of arc blocks (245) inside it will no longer generate a pressing friction force with the photovoltaic support (17) and will be automatically reset by the torsion spring (246). When resetting, the photovoltaic support (17) will no longer be driven to rotate.
