Traditional manual measurement with the help of tools can no longer meet the current high-efficiency and high-precision detection requirements.

[0003] For mobile phone screens, it includes both the detection of the entire panel and the detection of specific areas, such as the area of the Dynamic Island. Therefore, it is necessary to develop an integrated batch transmittance detection device. Summary of the Invention

In traditional detection, the screen is adsorbed and positioned on the download table and sent to the detection position for optical detection. However, in this way, the screen cannot be close to the detection unit, such as a CCD camera, an integrating sphere, etc. Therefore, the method of picking up, detecting, and transporting the screen adsorbed under the upload table is adopted. Secondly, for transmittance detection, an integrating sphere is used to comprehensively perform optical detection on multiple points on the screen surface to achieve spectral acquisition and output. This ensures high-precision and high-volume efficient transmittance detection. The overall solution is as follows.

[0007] Further, the transmittance detection mechanism includes a spectrometer, a laser focusing lens group, a laser source, and a light-shielding cover with a detection notch; the spectrometer is installed on the detection vertical plate frame through a spectrometer seat, and the laser focusing lens group is tiltably installed on the detection vertical plate frame through a laser mounting seat with adjustable angles and emits light downward toward the detection port of the spectrometer.

[0008] Further, the lower adsorption transfer table includes a lower suction plate, an adsorption adapter plate, a leveling plate, and an adsorption mounting plate frame, which are arranged from bottom to top and all have hollow openings in the middle; a leveling screw spring assembly is arranged between the leveling plate and the adsorption mounting plate frame, and the adsorption mounting plate frame is installed on the movable terminal of the transfer line through a transfer bottom plate; the hollow opening is adapted to the light source incident direction of the transmittance detection mechanism.
