Pre-alignment device and testing equipment

Abstract

The invention provides a pre-alignment device and detection equipment. The pre-alignment device includes a fixed structure and a pre-alignment structure, the pre-alignment structure is movably connected to the fixed structure, and the pre-alignment structure is located on the stage carrying the substrate to be tested in the pre-alignment state, and the pre-alignment structure includes The baffles and stoppers respectively define the position of the substrate to be tested in the first direction and the second direction perpendicular to each other. In the pre-alignment state, the baffles and / or stoppers are in line contact with the stage surface The part is located at the end of the baffle and / or the stopper which is in contact with the substrate to be tested. The pre-alignment device can relatively reduce or eliminate the gap between the baffle plate and the stage surface and the contact position between the stopper and the stage surface, so that the thinner substrate to be measured is not easy to be inserted into the baffle plate and the stage surface during the pre-alignment process. In the gap between the stage surface and the stopper and the stage surface, the pre-alignment accuracy and manual loading efficiency of the substrate to be tested are effectively improved, and the stable test of the substrate to be tested is ensured.

Description

Technical field[0001]The invention belongs to the technical field of display product detection and alignment, and specifically relates to a pre-alignment device and detection equipment.Background technique[0002]In the process of panel display product lighting detection, manual loading is required for all manual lighting equipment, regardless of rigid or flexible products. At present, the manual loading pre-alignment mechanism usually adopts X-direction and Y-direction movable limit blocks. The movable limit blocks are fixed on the carrier when they are used. When products of different sizes are switched, they need to be disassembled and moved for two limits. The position of the bit block in order to realize the function of pre-alignment.[0003]The movable limit block is troublesome to disassemble and replace, and there are more mechanical contacts with the table surface, which will damage the carrier surface; in addition, due to the overall manufacturing process, assembly accuracy, m...

AI Technical Summary

Problems solved by technology

[0003] It is troublesome to disassemble and replace the movable limit block, and it has more mechanical contact with the carrier surface, which will cause greater damage to the carrier surface; in addition, due to the overall manufacturing process, assembly accuracy, material characteristics, etc., the movable limit block There is a certain gap between the contact surface with the carrier, and the flexible display product has the characteristics of ultra-thin, it is very easy for the product to be inserted into the gap between the contact surface when the material is manually loaded, resulting in alignment deviation and Difficulty in personnel operation seriously affects work efficiency
