[0016] like Figures 1 to 3 As shown, in this embodiment, the box body 20 includes a left vertical plate 200, a right vertical plate 201 and an upper cover plate 202.

It can be seen that the box body 20 forms a closed environment with various plates, providing a dark room environment for the standard light source, which can reduce the influence of the environment on the detection results.

[0017] like Figure 1 to Figure 2 As shown, in this embodiment, the lens module 3 includes a telecentric lens 30 and a lens introduction block 31, and the lens introduction block 31 is provided with a first through hole that is limitedly matched with the telecentric lens 30, and the lens introduction block 31 is fixedly matched with the carrier 4. It can be seen that the lens module 3 adopts a telecentric lens 30, and the telecentric lens has an ultra-wide depth of field, which can completely cover the standard light source 24, eliminating the problem of different magnifications caused by the inconsistent distance between the measured object and the lens, and the telecentric lens 30 is limitedly matched with the lens introduction block 31 through the first through hole, and the lens introduction block 31 is fixedly accompanied with the carrier 4.

[0018] like Figures 1 to 4As shown, in this embodiment, the display module 2 also includes a calibration plate 23 and a standard light source 24, the calibration plate 23 is fixedly matched on the movable plate 21, the standard light source 24 is fixedly matched on the side of the movable plate 21 close to the lens introduction plate 22, a scale plate 203 is provided on the upper cover plate 202, the scale plate 203 cooperates with the calibration plate 23, a second through hole is provided on the lens introduction plate 22, and the second through hole cooperates with the lens module 3. It can be seen that the display module 2 is connected to the lens module 3, the standard light source 24 should be provided on the side of the movable plate 21 close to the lens introduction plate 22, the lens module 3 can better obtain the light of the standard light source 24, reduce the detection error, and the lens introduction plate 22 is provided with a second through hole to facilitate the cooperation of the lens module 3 with the display module 2.

[0019] like Figure 2 As shown, in this embodiment, the left vertical plate 200 and the right vertical plate 201 are both provided with a second notch 25 on the side close to the movable plate 21, and the movable plate 21 is provided with a pin 210 that slidably cooperates with the second notch 25.

[0020] like Figure 1 and Figure 2 As shown, in this embodiment, the detection module 1 includes a brightness meter 10, and the brightness meter 10 is connected to one end of the telecentric lens 30 near the lens introduction block 31. It can be seen that the detection module 1 is a brightness meter 10 to be tested, and different brightness meters 10 to be tested are connected to one end of the telecentric lens 30 near the lens introduction block 31. The brightness meter 10 obtains the light emitted by the same standard light source 24 through the telecentric lens 30, and the different brightness meters 10 are tested accordingly.

[0022] In this embodiment, the working principle of the utility model is as follows:

[0023] like Figures 1 to 4 As shown, when the detection module 1 needs to detect the display module 2, it pushes and pulls the calibration plate 25, and the movable plate 21 follows the calibration plate 23 to move on the carrier 4. The pin 210 slides under the guidance of the second notch 25 of the left vertical plate 200 and the right vertical plate 201 and the first notch 40 of the carrier plate 4 to adjust the relative distance between the standard light source 24 and the lens module 3.
