Therefore, an integrated detection device needs to be developed. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a screen comprehensive measurement device, which can solve the above problems.

[0006] Further, the screen comprehensive measurement device further includes a flatness measurement unit, which is used for measuring the overall flatness or flatness of the screen.

[0007] Further, the screen comprehensive measurement device further includes a longitudinal transfer line and a fixture stage; the longitudinal transfer line is arranged on one side of the measurement frame, driving the fixture stage to move back and forth longitudinally; the top surface height of the carrier plate of the fixture stage is adapted to the measurement heights of the long-side measurement unit, the end comprehensive measurement unit, the end local measurement unit, and the flatness measurement unit.

[0008] Further, the long-side measurement unit, the end comprehensive measurement unit, and the end local measurement unit all include a measurement camera, a measurement lens, a backlight source, and a front light source arranged from bottom to top. The screen to be measured on the fixture stage is moved between the backlight source and the front light source for measurement.

[0009] Furthermore, the fixture stage adopts a linkage side push-clamp positioning mechanism, which includes a hollow bottom plate, a product-supporting hollow suction plate, a long-side fixed stop component, a short-side fixed stop component, a long-side push-clamp positioning component, a short-side push-clamp positioning component, and a side positioning linkage driving component; a rectangular hollow opening is formed in the middle of the hollow bottom plate, and the long side of the product-supporting hollow suction plate is fixed to the long-side plate of the hollow opening of the hollow bottom plate through an extension part; the long-side push-clamp positioning component and the short-side push-clamp positioning component are driven in a linkage manner by the side positioning linkage driving component to perform side push-clamp positioning on the products on the product-supporting hollow suction plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: through the integrated and staggered arrangement of multiple measurement units, the present application effectively measures the four sides and local special areas of the screen at one time. Combined with the flatness measurement unit, batch high-efficiency intelligent measurement is achieved, ensuring the imaging quality of the screen and facilitating popularization and application in the detection field of transparent plates such as 3C.
