Description

Novel AOI vacuum test equipment that is shaded

Technical Field

The utility model belongs to the technical field related to display screen detection, and particularly relates to novel AOI (argon oxygen decarburization) backlight vacuum detection equipment.

Background

The display screen backlight module is formed by reflecting cold cathode fluorescent lamps upwards through a light guide plate on an optical diaphragm and irradiating upwards through the optical diaphragm to reflect light uniformly. Because the air cleanliness of a workshop and the logistics pollution of incoming materials in the assembling process can cause the surfaces of parts to have fine stains, and the fine stains can not be screened out in the assembling process, light is slightly shielded in a product after the assembling process. The product is composed of multiple layers of materials, each layer is an air partition, and fine stains in the product cannot be effectively detected during conventional lighting detection after assembly, so that defective products flow into the downstream.

In the prior art, a film is pressed and then is subjected to vacuum detection, and one film needs to be replaced after being used for 10 times. And after the film is vacuumized for many times, indentation is caused to affect the detection result of AOI. Changing the film is also cumbersome and creates a consumable. Each replacement requires a shutdown and greatly affects the operational run time of the equipment.
