When the solar panel moves to the inspection station, a light source assembly located below the solar panel illuminates the solar panel from bottom to top, while a camera located above the solar panel captures the solar panel image for quality inspection. If a crack is found in the inspected solar panel, light from the light source assembly will pass through the crack, and the camera will capture the defect. Furthermore, in the present invention, because the camera and the light source assembly are horizontally offset in the first direction, the camera can capture the solar panel without being in direct line of sight with the light from the light source assembly. This prevents light from passing through cracks in defective solar panels and affecting the camera's image quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Reference Figures 1 to 3 In an embodiment of the present utility model, a photovoltaic panel detection device is provided, including a conveyor belt 100, a bracket 300, a light source assembly 400 and a camera 500.

[0030] Among them, the conveyor belt 100 is used to horizontally support and convey the solar panel 200 horizontally along the first direction. The conveyor belt 100 passes through the inspection station. The bracket 300 is set at the inspection station. The light source assembly 400 is set on the bracket 300 and is located below the solar panel 200 supported by the conveyor belt 100. The light source assembly 400 is configured to emit light upward. The camera 500 is set on the bracket 300 and is located above the conveyor belt 100. The horizontal positions of the camera 500 and the light source assembly 400 in the first direction are staggered with each other. The camera 500 is configured to obliquely shoot the solar panel 200 conveyed to the inspection station.

[0031] It is understood that during the inspection process, the conveyor belt 100 horizontally supports the panel 200 and conveys the panel 200 horizontally along a first direction. When the panel 200 moves to the inspection station, the light source assembly 400 located below the panel 200 can illuminate the panel 200 from bottom to top, while the camera 500 located above the panel 200 can capture an image of the panel 200 to perform quality inspection on the panel 200. If a crack is found in the inspected panel 200, the light emitted by the light source assembly 400 will pass through the crack on the panel 200, and the camera 500 will also capture the defect location. In addition, in the present invention, because the horizontal positions of the camera 500 and the light source assembly 400 are staggered in the first direction, the camera 500 can capture the panel 200 without being in direct line of sight with the light emitted by the light source assembly 400. This prevents light from passing through the cracks of the defective panel 200 and affecting the camera 500's imaging accuracy.

[0032] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the setting angle of the camera 500 relative to the bracket 300 is adjustable. In order to adjust the illumination angle of the camera 500, the detection device of the present invention can be suitable for photographing solar panels 200 of different sizes and shapes.

[0033] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, a support bracket 310 is provided on a bracket 300, and the support bracket 310 is connected to a support plate 320. The support bracket 310 is provided with a hinge hole 311 and an arc-shaped slot 312. The center of the hinge hole 311 coincides with the center of the arc-shaped slot 312. The support plate 320 is provided with a hinge (not shown) and a sliding member (not shown). The hinge is plugged into the hinge hole 311, and the sliding member is slidably arranged in the arc-shaped slot 312 and can be fixed at any position in the arc-shaped slot 312. The camera 500 is set on the support plate 320. When it is necessary to adjust the shooting angle of the camera 500, the setting angle of the camera 500 can be indirectly adjusted by adjusting the setting angle of the support plate 320. Specifically, both the hinge and the slider can be bolts. The support plate 320 can have threaded holes that threadably engage with the hinge and slider, respectively. The hinge can pass through the hinge holes 311 and threadably engage with one of the threaded holes, while the slider can pass through the arcuate slot 312 and threadably engage with the other threaded hole. Once the camera 500 is adjusted to the desired angle, the support plate 320 can be fixed by tightening the bolts.

[0034] Reference Figure 1 and Figure 3In one embodiment of the present invention, the position of the support bracket 310 relative to the bracket 300 is adjustable along a first direction and a second direction, thereby arbitrarily adjusting the horizontal position of the camera 500. The second direction is a horizontal direction and perpendicular to the first direction. For example, when the first direction is a front-to-back direction, the second direction is a left-to-right direction.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the light source assembly 400 includes a light source body 410 and an adjustment assembly 420. The adjustment assembly 420 is connected to the bracket 300. The light source body 410 is disposed on the adjustment assembly 420. The adjustment assembly 420 is positionally adjustable relative to the bracket 300 in a vertical direction and a second direction. The second direction is a horizontal direction and is perpendicular to the first direction. The light source body 410 is positionally adjustable relative to the adjustment assembly 420 in the first direction. Through the above arrangement, the position of the light source assembly 400 relative to the bracket 300 can be adjusted in both the horizontal and vertical positions according to actual conditions, thereby improving the adaptability of the detection device of the present invention.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the adjustment assembly 420 includes a first connecting plate 421, a second connecting plate 422 and a third connecting plate 423, the first connecting plate 421 extends along the second direction and is connected to the bracket 300, and the position of the first connecting plate 421 relative to the bracket 300 along the second direction is adjustable, so as to adjust the position of the light source body 410 in the second direction; the second connecting plate 422 extends along the first direction and is connected to the first connecting plate 421, the light source body 410 is connected to the second connecting plate 422 and the position relative to the second connecting plate 422 along the first direction is adjustable, so as to adjust the position of the light source body 410 in the first direction; the third connecting plate 423 is vertically arranged, one end of the third connecting plate 423 is connected to the end of the second connecting plate 422 away from the first connecting plate 421, and the other end is fixedly connected to the bracket 300, and the position of the second connecting plate 422 relative to the third connecting plate 423 along the vertical direction is adjustable, so as to adjust the position of the light source body 410 in the vertical direction.

[0037] In one embodiment of the present invention, the acute angle between the shooting angle of the camera 500 and the horizontal plane is between greater than or equal to 45 degrees and less than or equal to 60 degrees, so that the camera 500 can shoot the solar panel 200 at a suitable angle without directly looking at the light source.

[0038] like Figure 1As shown, in one embodiment of the present invention, the conveyor belt 100 includes two belt bodies 110, which are spaced apart and have an irradiation space therebetween. The light source assembly 400 is configured to pass through the irradiation space and irradiate the solar panel 200 upwards. Figure 1 The conveyor belt 100 and the solar panel 200 are indicated by dotted lines to prevent them from blocking other components.

[0039] 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.
