DETAILED DESCRIPTION

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] like Figure 1-Figure 5 As shown, a camera assembly with auxiliary positioning function includes a camera body 1, an annular frame 2 sleeved outside the camera body 1, and four laser lamps 3 installed on the annular frame 2; the four laser lamps 3 are arranged in a circular array and form a beam spot 7 in front of the camera body 1, and the four laser lamps 3 correspond to the four sides of the photovoltaic assembly 6 respectively. When the four sides of the photovoltaic assembly 6 are located in the area surrounded by the beam spots 7, the photovoltaic assembly 6 is completely located within the shooting range of the camera body 1. The angle between the center of the laser lamp 3 and the center of the camera body 1 is adjustable, and the inclination angle of the laser lamp 3 can be adjusted according to the side length of the photovoltaic assembly 6.

[0027] The specific method of use is: first put the annular frame 2 on the camera body 1 and fix it, then adjust the camera aperture, for example, adjust the aperture to the maximum, and then test the first photovoltaic module 6. Observe the camera lens 101 to ensure that the photovoltaic module 6 is completely located in the lens 101, then adjust the lights of the four laser lights 3 so that the photovoltaic module 6 is located in the area surrounded by the beam point 7, that is, there is no light on the surface of the photovoltaic module 6, and preferably the beam point 7 is tangent to the side of the photovoltaic module 6. At this time, fix the four laser lights 3, and then when measuring photovoltaic modules 6 of the same size, just place the photovoltaic module 6 in the area surrounded by the beam point 7, and there is no need to check the lens 101 all the time.

[0028] The annular frame 2 can be fixed outside the lens 101 of the camera body 1. The lens 101 is approximately cylindrical, and the annular frame 2 is in the shape of a ring.

[0029] The annular frame 2 and the lens 101 are preferably fixed by screws. Specifically, the annular frame 2 is provided with a first screw hole 201, and the locking screw 4 passes through the first screw hole 201 and abuts against the lens 101 for fixing (such as Figure 2 To prevent the outer surface of the lens 101 from being worn, a rubber layer may be provided on the outer surface of the lens 101, and the locking screw 4 abuts against the rubber layer, which can prevent wear and play an anti-slip role.

[0030] The laser lamp 3 can be a model that emits a single straight beam, such as a laser pen or a laser flashlight. During the initial adjustment, the side of the photovoltaic module 6 is tangent to the beam emitted by the laser lamp 3 (e.g. Figure 7 As shown), the requirement can be met as long as the side of the photovoltaic component 6 measured each time thereafter is located inside the light beam emitted by the laser lamp 3.

[0031] The laser lamp 3 may also be a model that emits multiple straight beams. In this case, the beams of adjacent laser lamps 3 may cross to form a grid point 8 (or a lampshade may be used to cover the redundant grid points 8). When adjusting, the side of the photovoltaic module 6 is located at the intersection grid points 8 formed by the straight beams of different laser lamps 3, especially at the grid points 8 located in a smaller range (such as Figure 8 As shown), the requirement can be met as long as the side of the photovoltaic component 6 is located inside the grid point 8 each time it is measured.

[0032] Laser light 3 angles adjustment:

[0033] like Figure 3 and Figure 4 As shown, the outer circumferential surface of the annular frame 2 is provided with a bracket 5 for mounting the laser lamp 3, and the bracket 5 includes two support plates 501 fixed to the annular frame 2 and a top plate 502 fixed to the support plates 501, and the top plate 502 is arranged opposite to the annular frame 2; a rotating shaft 301 is fixed on both sides of the rear of the laser lamp 3, and a shaft sleeve 503 for sleeve-mounting the rotating shaft 301 is provided on the support plate 501, and a second screw hole 504 is provided on the top plate 502, and an adjusting screw 505 passes through the second screw hole 504 and abuts against the front of the laser lamp 3; an extrusion spring 506 is also provided between the front of the laser lamp 3 and the annular frame 2. The adjusting screw 505 is used to push the front of the laser lamp 3, and the laser lamp 3 can rotate around the rotating shaft 301. The extrusion spring 506 is opposite to the adjusting screw 505 to fix the front of the laser lamp 3. When it is necessary to shrink the tilt angle of the laser lamp 3, the adjusting screw 505 is screwed inward, and the contraction amount of the extrusion spring 506 increases, that is, from Figure 5 Adjust to Figure 6 , Figure 5 The corresponding photovoltaic assembly 6 has a higher height, and vice versa, the adjusting screw 505 is screwed outward, and the contraction amount of the squeezing spring 506 is reduced.

[0034] Preferably, a bottom plate 507 is fixedly attached to the outer surface of the annular frame 2 , and the extrusion spring 506 and the support plate 501 are both fixed on the bottom plate 507 .
