[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] One or more embodiments of the present invention provide a welding tool for photovoltaic panels, which will be described below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the welding tool for the photovoltaic panel 50 described in the present application includes a flattening component, a weld positioning component and a flipping component.

[0032] Among them, the flattening component includes two pressing plates 20 arranged opposite to each other in the vertical direction, and the two pressing plates 20 are configured to be displaced toward each other to flatten the photovoltaic panel 50; the weld positioning component includes a weld identification element, and a rotating plate 30 mounted on the pressing plate 20 relatively below, and the rotating plate 30 is configured to rotate circumferentially synchronously with the pressing plate 20; after the weld identification element identifies the area to be welded of the photovoltaic panel 50, the rotating plate 30 drives the pressing plate 20 to rotate so that the area to be welded of the photovoltaic panel 50 is rotated to a preset position; the flipping component includes a displacement robot arm 40 and a fixed claw 41 provided on the displacement robot arm 40, the fixed claw 41 is used to fix the photovoltaic panel 50, the fixed claw 41 moves in the horizontal direction with the displacement robot arm 40, and can be displaced in the vertical direction relative to the displacement robot arm 40, and the displacement robot arm 40 is provided with a flipping drive component 45 for driving the fixed claw 41 to flip.

[0033] From the above description, it can be seen that the photovoltaic panel 50 provided in the present application uses a welding tool, which first flattens the photovoltaic panel 50 using a flattening component, and then locates the area to be welded of the photovoltaic panel 50 through the weld positioning component, and rotates the photovoltaic panel 50 to a preset position to facilitate welding by an external welding robot. Since both the upper and lower surfaces of the photovoltaic panel 50 need to be welded, the flipping component can facilitate flipping the photovoltaic panel 50 so that both surfaces of the photovoltaic panel 50 can be welded. The entire process does not require manual participation, has a high degree of automation, saves a lot of labor costs, and is conducive to improving production efficiency.

[0034] It should be noted that, in the embodiment of the present application, the photovoltaic panel 50 is exemplarily an annular plate, that is, an end plate used to be fixed to the end of the photovoltaic pipe pile, and the end plate is in the shape of a flange. Since the initially cast end plate is not a flat plate, the end plate can be flattened by using a flattening assembly. Of course, for different implementation scenarios, the actual shape of the photovoltaic panel 50 is different, and this is only illustrated in the embodiment of the present application.

[0035] like Figure 1 and Figure 2 As shown, the welding tool for photovoltaic panels 50 described in the present application further includes a support frame 10, and the flattening assembly, the weld positioning assembly and the flip assembly are all arranged on the support frame 10. Here, the support frame 10 can be made of high-strength steel material.

[0036] In the above embodiment, the support frame 10 is further provided with a linear driving component 12, and one of the two pressing plates 20 is fixed on the support frame 10, and the other pressing plate 20 is driven to move by the linear driving component 12. Here, the linear driving component 12 can be a hydraulic cylinder, and the upper end of the hydraulic cylinder is fixedly connected to the lower pressing plate 20. When the photovoltaic panel 50 is transported from the outside, the hydraulic cylinder drives the lower pressing plate 20 to move upward, thereby flattening the photovoltaic panel 50 in the middle.

[0037] In the above embodiment, a stand can be set on the support frame 10, and the pressing plate 20 located above is transversely fixed on the stand, so that the two pressing plates 20 are arranged in relative positions. Since the photovoltaic panel 50 needs to be turned over for welding later, the stand will interfere with the turning over and welding of the photovoltaic panel 50. Therefore, the subsequent displacement robot 40 can be used to first move away from the pressing plate 20, then raise the photovoltaic panel 50, and finally approach the automatic welding robot again to complete the welding of the turning over work. The raising action is to avoid interference with the stand. In the embodiment described in the present application, the pressing plate 20 located relatively below is provided with a boss protruding in the thickness direction, and the photovoltaic panel 50 is engaged with the boss 21. Here, exemplarily, when the photovoltaic panel 50 is an annular plate, the photovoltaic panel 50 is sleeved on the boss 21 to constitute a radial constraint of the photovoltaic panel 50 to prevent the photovoltaic panel 50 from deviating and affecting the subsequent welding work. Therefore, the shape of the boss 21 is adapted to the inner diameter of the annular plate, and the outer diameter of the boss 21 is slightly smaller than the inner diameter of the annular plate. When the photovoltaic panel 50 is a panel of other shapes, the boss 21 can also be adjusted accordingly as long as the fixing effect with the photovoltaic panel 50 is ensured.

[0038] It should be noted that, in some embodiments, illustratively, the thickness of the boss 21 is less than or equal to the thickness of the photovoltaic panel 50, that is, when the photovoltaic panel 50 is mounted on the boss 21, the uneven and spiral photovoltaic panel 50 will be flattened first when the two pressure plates 20 are squeezed, thereby ensuring the flatness of the photovoltaic panel 50.

[0039] The above-mentioned weld seam identification element can adopt a component in the related technology that can identify the area to be welded. For example, a machine vision recognition system is integrated on the support frame 10. The system can take real-time photos of the photovoltaic panel 50 before welding and perform image analysis to determine the actual position, angle, width and other parameters of the weld, thereby guiding the automatic welding robot to accurately locate and implement the welding operation. Alternatively, a dedicated sensor or weld seam tracking device is set on the support frame 10 to detect the position and shape of the weld through electromagnetic, laser or infrared technical principles to ensure the accurate execution of the welding process. In practical applications, these technologies and equipment together constitute a part of the intelligent welding production line, which significantly improves the welding quality and production efficiency.

[0040] It should be noted that the area to be welded described in the embodiment of the present application refers to the joint position of adjacent edges extending outward in the radial direction of the photovoltaic panel 50, and the automatic welding robot can perform welding work on the weld at the preset position. The preset position can be set in advance, for example, determined by three-dimensional coordinates.

[0041] like Figure 1 As shown, in some embodiments, the support frame 10 is provided with a slide rail 11 extending in the horizontal direction, and the displacement mechanical arm 40 is provided with a horizontal driving component 46, and the horizontal driving component 46 drives the displacement mechanical arm 40 to move on the slide rail 11 to approach or move away from the pressing plate 20. In addition, the displacement mechanical arm 40 includes a base 42 that cooperates with the slide rail 11, and a telescopic bracket 43 provided on the base 42, and the fixed claw 41 is provided on the telescopic bracket 43; the displacement mechanical arm 40 is provided with a vertical driving component 44, and the vertical driving component 44 drives the telescopic bracket 43 to move in the vertical direction. Here, the horizontal driving component 46 and the vertical driving component 44 can adopt linear driving components in the relevant technology, such as linear driving motors.

[0042] In some embodiments, the fixed claws 41 are two provided on the displacement robot arm 40, and the two fixed claws 41 are located on the same plane. The fixed claws 41 include two clamping plates 411 arranged opposite to each other in the vertical direction, and also include a clamping driving component 47 for driving the two clamping plates 411 to clamp. The clamping driving component can be a hydraulic component to clamp the photovoltaic panel 50 by hydraulic pressure.

[0043] Since the clamping plates 411 on the fixed claw 41 are relatively arranged in the vertical direction, when the fixed claw 41 moves with the displacement robot arm 40 close to the flattening assembly, the clamping plates 411 will gradually extend into the photovoltaic panel 50, and then the clamping driving component 47 can be used to drive the clamping plates 411 to clamp the photovoltaic panel 50.

[0044] The flip driving component 45 provided for the above-mentioned fixed claw 41 is a motor in the related art, and the output shaft end of the motor is coaxially fixed with the fixed claw 41. When the output shaft of the motor rotates, the fixed claw 41 is driven to rotate circumferentially. Furthermore, the flip angle of the fixed claw 41 is 180°. After the fixed claw 41 flips 180°, the photovoltaic panel 50 fixed by the fixed claw 41 is turned over so that the unwelded side faces upward, which is convenient for the subsequent automatic welding robot to continue welding.

[0045] It should be noted that after the fixing claw 41 is flipped, the actual position of the photovoltaic panel 50 is not the aforementioned preset position. Therefore, another preset position needs to be additionally set so that the automatic welding robot can perform welding work on the photovoltaic panel 50 at the preset position.

[0046] An exemplary use process of the welding tool for the photovoltaic panel 50 described in the present application is as follows:

[0047] The photovoltaic panel 50 that has been initially cast is transported by external equipment and placed on the pressure plate 20 relatively below. At this time, the photovoltaic panel 50 is snap-fitted with the boss 21 on the pressure plate 20. Then, after the weld identification element identifies the area to be welded of the photovoltaic panel 50, the rotating plate 30 drives the pressure plate 20 to rotate, so that the area to be welded of the photovoltaic panel 50 is rotated to a preset position, and the automatic welding robot performs welding on the area to be welded.

[0048] After welding is completed, the displacement robot arm 40 moves toward the flattening assembly, and the fixed claw 41 clamps the photovoltaic panel 50. The displacement robot arm 40 moves in the direction away from the flattening assembly. Then, the telescopic bracket 43 rises under the driving action of the vertical driving component 44, and the flip driving component 45 drives the fixed claw 41 to flip, and drives the displacement robot arm 40 again to approach the flattening assembly. During this process, the fixed claw 41 passes over the bracket that fixes the card plate relatively above and enters another preset position. The automatic welding robot performs welding work on the photovoltaic panel 50 at the preset position to complete the overall welding of the photovoltaic panel 50.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
