Moreover, the light-shielding cylinder 11 can reciprocate longitudinally under the drive of the driving assembly 2. When the light-shielding cylinder 11 moves to the installation station, the internal cavity of the light-shielding cylinder 11 and the installation station will form a light source cavity for detecting the photosensitive product 6.

[0038] Specifically, see Figure 3-Figure 5 As shown, the above-mentioned driving component 2 includes a mounting plate 1 and a telescopic device. The mounting plate 1 is vertically connected to the upper surface of the working panel 17 and is located on one side of the installation station, while the telescopic device is fixed to the end of the mounting plate 1 away from the working panel 17. The output end of the telescopic device is connected to the movable component 5, and the movable component 5 drives the light-shielding tube 11 to reciprocate longitudinally.
