Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0029] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0030] In an embodiment of the present invention, a surface optical detection device for a photovoltaic panel 200 is provided, comprising a conveyor line 100 , a rack 300 , a light source 400 and a camera 500 .

[0031] Among them, the conveyor line 100 is used to horizontally support and convey the photovoltaic panel 200 forward. The conveyor line 100 passes through the inspection station. The rack 300 is set at the inspection station. The rack 300 has a shooting hole 321. The shooting hole 321 is located above the conveyor line 100. The light source 400 is set on the rack 300. The light source 400 is located obliquely above the shooting hole 321 and is inclined to illuminate in the direction of the shooting hole 321. The light emitted by the light source 400 can pass through the shooting hole 321 and illuminate the photovoltaic panel 200 moved to the bottom of the shooting hole 321. The camera 500 is set on the rack 300 and is located directly above the shooting hole 321.

[0032] It is understandable that when the conveyor line 100 conveys the photovoltaic panel 200 to the inspection station, the illumination light emitted by the light source 400 can pass through the shooting hole 321 and illuminate the photovoltaic panel 200 located directly below the shooting hole 321 at an angle. At the same time, the camera 500 located directly above the shooting hole 321 can photograph the photovoltaic panel 200. In the inspection device of the embodiment of the present utility model, since the light source 400 illuminates the photovoltaic panel 200 at an angle, the camera 500 and the light source 400 are prevented from blocking each other, thereby ensuring the clarity of the camera 500's photography and improving the inspection accuracy of the photovoltaic panel 200.

[0033] It should be noted that the conveyor line 100 in the present invention can be set to intermittent movement, that is, when the photovoltaic panel 200 to be inspected moves to directly below the shooting hole 321, the conveyor line 100 stops moving, and when the camera 500 completes shooting of the photovoltaic panel 200, the conveyor line 100 continues to transport forward.

[0034] In addition, if Figure 2 As shown, since a shooting hole 321 is provided in the present invention, after the light of the obliquely irradiated light source 400 is reflected on the surface of the photovoltaic panel 200, most of the light will be reflected on the bottom surface of the rack 300 and the surface of the photovoltaic panel 200, thereby increasing the surface brightness of the photovoltaic panel 200 and further improving the detection accuracy.

[0035] like Figure 3 and Figure 4As shown, in some embodiments of the present invention, the photographing hole 321 is a rectangular hole extending longitudinally through the frame 300, with the long side of the photographing hole 321 extending in the left-right direction. The light source 400 is a long strip light source 400 extending in the left-right direction. The rectangular photographing hole 321 may correspond to the area to be inspected on the photovoltaic panel 200. The long strip light source 400 ensures uniform light intensity on the photovoltaic panel 200.

[0036] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the frame 300 includes a vertical plate 310, a bottom plate 320, and a top plate 330. The bottom plate 320 is horizontally disposed, with a photographing hole 321 defined therein. The top plate 330 is horizontally disposed above the bottom plate 320. The vertical plate 310 is vertically disposed, with its upper and lower ends connected to the top plate 330 and the bottom plate 320, respectively. The camera 500 is mounted on the top plate 330. The top plate 330 can be vertically adjustable relative to the vertical plate 310 to adjust the photographing distance of the camera 500 relative to the photovoltaic panel 200.

[0037] like Figure 1 、 Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the rack 300 further includes four columns, which are respectively arranged on the base plate 320. The rack 300 is erected above the conveyor line 100 through the four columns, so that the rack 300 can be stably supported.

[0038] Further, refer to Figure 4 In some embodiments of the present invention, a connecting piece 340 is provided on each column, and a strip hole 341 is opened on the connecting piece 340. The bottom plate 320 is connected with four bolts. The four bolts are threadedly connected to the bottom plate 320 after passing through the corresponding strip holes 341 respectively. Through the cooperation of the bolts and the connecting piece 340, the overall horizontal position of the rack 300 can be adjusted.

[0039] In some embodiments of the present invention, the angle of the light source 400 relative to the frame 300 is adjustable. Two support plates 322 may also be provided on the base plate 320, each hinged to the ends of the light source 400. By providing an arcuate groove on the base plate 320, the angle adjustment range of the light source 400 can be limited. The present invention is simple to operate, as it allows the light to coincide with the center of the camera 500 simply by adjusting the illumination angle of the light source 400. Furthermore, in some embodiments of the present invention, the acute angle between the illumination angle of the light source 400 and the horizontal plane is between greater than 45 degrees and less than or equal to 80 degrees.

[0040] In some embodiments of the present invention, the camera 500 is configured to rotate around its own axis so that the camera imaging line coincides with the light line of the light source 400 without generating an angle intersection.

[0041] The above description further details the present invention in conjunction with specific preferred embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. A person skilled in the art of the present invention will appreciate that its architecture is flexible and adaptable, allowing for the development of a series of products without departing from the present invention's concept. Simple deductions or substitutions should be considered within the scope of patent protection for the present invention as defined by the submitted claims.
