It should be noted that the cabinet 100 is rectangular and placed horizontally. The product to be photographed is placed in front of the opening 101 through an external device and is facing the center of the opening 101. When installing the camera 200, the lens to be used has been lifted and installed on the camera 200, and the lens of the camera 200 is also facing the center of the opening 101, so that the camera 200 can take a more comprehensive picture of the product. The spectrometer 300 is made of a transparent material so that the spectrometer 300 can reflect light and enable the camera 200 to photograph the product through the spectrometer 300. The light source 400 is a light board, on which are provided lamp beads for emitting light. The cabinet 100 is also provided with a network port 105. The external server is connected to the control main board 500 through the network port 105, and can be used to power the camera 200 and the light source 400.

The cabinet 100 is also provided with an identification film 106, which can display the basic information of the device to facilitate the staff's understanding. The device realizes the integrated design of the detection device by reasonably assembling the components required for various tests in a cabinet 100.

[0039] The beneficial effects of the present invention are as follows: the light source 400 shines on the spectrometer 300, and the light is reflected by the spectrometer 300 on the product at the opening 101, so that the light source 400 indirectly illuminates the product, so that the camera 200 can directly shoot the product, and the light source 400 and the camera 200 are both arranged in the cabinet 100, so that the structure of the detection device is more compact, realizing the integrated design of the detection device, and the cabinet 100 can also play a protective role for the camera 200 and the light source 400, which is beneficial to improving the service life of the camera 200 and the light source 400.

[0040] Please refer to Figure 3 In one possible embodiment, a bracket 201 is provided within the cabinet 100, and the camera 200 is mounted on the bracket 201. It should be noted that studs are provided on the inner sidewall of the cabinet 100, and the bracket 201 is mounted on the studs via bolts. The provision of the bracket 201 not only provides a mounting base for the camera 200, but also allows the camera 200 to be suspended relative to the cabinet 100, so that the lens of the camera 200 is aligned with the center of the opening 101, facilitating a more comprehensive image of the product.

[0041] Please refer to Figure 2 and Figure 4 In one possible embodiment, a first mounting groove 301 is provided on the inner wall of the cabinet 100. The first mounting groove 301 is arranged at an angle, and the beam splitter 300 is disposed in the first mounting groove 301. It is easy to understand that when installing the beam splitter 300, it is only necessary to insert the beam splitter 300 into the outlet of the first mounting groove 301. The first mounting groove 301 can limit the beam splitter 300, thereby fixing the beam splitter 300 to the cabinet 100.

[0042] Please refer to Figure 2 In one possible embodiment, a first diffuser plate 401 is further provided in the cabinet 100 and is disposed between the beam splitter 300 and the light source 400. It is readily understood that the first diffuser plate 401 diffuses the light emitted by the light source 400, thereby improving the uniformity and softness of the light and enabling the camera 200 to capture clear images.

[0043] Please refer to Figure 2 and Figure 4 In one possible embodiment, a second mounting groove 402 is defined on the inner wall of the cabinet 100, and the first diffuser plate 401 is disposed within the second mounting groove 402. It is readily understood that, when installing the first diffuser plate 401, it is sufficient to simply insert the first diffuser plate 401 into the outlet of the second mounting groove 402. The second mounting groove 402 serves to limit the first diffuser plate 401, thereby securing the first diffuser plate 401 to the cabinet 100.

[0044] Please refer to Figure 2In one possible embodiment, a convex lens 600 is further provided in the cabinet 100 and is located between the opening 101 and the beam splitter 300. It is readily understood that the convex lens 600 can magnify the image and change the focal length of the camera 200, allowing the camera 200 to capture clearer images. Furthermore, the number of convex lenses 600 can be freely designed based on actual needs. In this device, there are two convex lenses 600, which are arranged side by side.

[0045] Please refer to Figure 2 and Figure 4 In one possible embodiment, a third mounting groove 601 is provided on the inner wall of the cabinet 100, and the convex lens 600 is disposed in the third mounting groove 601. It is easy to understand that when installing the convex lens 600, it is only necessary to extend the convex lens 600 from the exit of the third mounting groove 601. The third mounting groove 601 can limit the convex lens 600, thereby securing the convex lens 600 to the cabinet 100. Furthermore, the third mounting groove 601 is connected to the second mounting groove 402, and the lower end of the convex lens 600 contacts the first diffuser 401. Furthermore, the number of third mounting grooves 601 is the same as the number of convex lenses 600.

[0046] Please refer to Figure 3 and Figure 4 In a possible implementation, the cabinet 100 includes a main body 102 , an upper cover 103 , and a front cover 104 . The upper cover 103 and the front cover 104 are both detachably connected to the main body 102 . It should be noted that the opening 101 is arranged on the front cover 104, the first mounting groove 301, the second mounting groove 402 and the third mounting groove 601 are all arranged on the inner wall of the main body 102, and the upper cover 103 is used to block the outlets of the first mounting groove 301 and the third mounting groove 601 to prevent the spectrometer 300 and the convex lens 600 from sliding out, and the front cover 104 is used to block the outlet of the second mounting groove 402 to prevent the first diffuser plate 401 from sliding out. In addition, a step 107 is provided on the bottom surface of the main body 102, and the light source 400 is provided on the step 107 so that the middle part of the lamp board is suspended in the air, which is convenient for connecting the lamp board from the bottom surface, and a wire hole 108 is also provided on the main body 102, and the wires of the lamp board are connected to the control main board 500 through the wire hole 108.

[0047] Please refer to Figure 2In one possible embodiment, a second diffuser plate 403 is provided on the front cover 104, and the second diffuser plate 403 corresponds to the side of the light source 400. It should be noted that lamp beads can also be provided on the side of the light board to allow light to be emitted from the side of the light source 400. The second diffuser plate 403 provided on the side of the light source 400 can diffuse the light emitted from the side of the light source 400, which is conducive to improving the uniformity and softness of the light, making the light irradiated on the product softer, and avoiding the situation where the light source 400 can only illuminate the product through reflection from the beam splitter 300. When the product is not facing the opening 101, the light source 400 can also illuminate the product through the second diffuser plate 403, providing another way for the light source 400 to illuminate the product.

[0048] Please refer to Figure 5 In one possible embodiment, a tripod 700 is further provided at the front end of the cabinet 100. The inner side of the tripod 700 is a reflective surface 701, which corresponds to the opening 101. It should be noted that when a product cannot be placed in the opening 101 or when a staff member needs to photograph the side of the product, the product can be moved downward so that it is located at the second diffuser plate 403, and the tripod 700 is placed on the cabinet 100. The reflective surface 701 of the tripod 700 is a mirror surface. The product can be presented in the mirror surface through the mirror principle. The camera 200 obtains an image of the product by photographing the mirror surface, and the light source 400 can illuminate the product through the second diffuser plate 403 to make the captured image clearer.

[0049] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
