Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1 and figure 2 As shown, a fully automatic LCD detection and control system based on AOI technology in the present invention includes an Inline line body PLC control module 1 and a detection workstation. The detection workstation is provided with an automatic crimping device 2, an AOI system 3 and a re-judgment workstation 4.

[0040] Inline PLC control module 1 is used to control the position of LCD panel a3 on the assembly line, and send the panel information to automatic crimping equipment 2 and AOI system 3 . The PLC control module 1 of the Inline line realizes automation through PLC, controls the inbound and outbound of the LCD panel a3 (a1 / a2 / a4 / a5), and carries and transmits the relevant information of the LCD panel a3, when the LCD panel a3 enters the detection workstation , the PLC control module 1 of...

Abstract

The invention discloses a full-automatic LCD detecting control system and method based on an AOI technology. The system comprises an Inline line body PLC module and a detecting workstation, wherein automatic compression joint equipment and an AOI system are arranged in the detecting workstation; the Inline line body PLC module is used for controlling the position of an LCD panel on an assembly line; the automatic compression joint equipment is used for controlling a motor to carry out automatic plug wire compression joint on the LCD panel of the detecting workstation; after plug wire compression joint is finished, the AOI system is informed to begin to detect; after a detection finish signal transmitted from the AOI system is received, a wire is automatically unplugged from the LCD panel; and the AOI system is used for receiving a detection beginning signal and then automatically optically detecting the LCD panel, generating a detecting information file, and transmitting the detecting finish signal to the automatic compression joint equipment. Disadvantages of manual detection can be overcome, the defect detection speed is high, the precision is also high, the system is automatic and practical, a non-contact mode is carried out, and the development prospect in the industry of defect detection of liquid crystal displays is wide.

Description

technical field [0001] The invention belongs to the technical field of automatic optical liquid crystal panel detection, and specifically refers to a fully automatic LCD detection control system and method based on AOI technology. Background technique [0002] Under the production capacity requirements of LCD panel manufacturers and the fierce competition environment, with the increase of labor costs and the continuous development of AOI (Automatic Optical Inspection Technology), the application in the field of LCD panels continues to mature. Compared with the production line The detection method of manually pointing the screen and cutting the picture by the staff and looking for defects with the naked eye relies on subjectivity and has the characteristics of high false detection and missed detection rate. With the advantages of high precision, automation, and non-contact, it can overcome the disadvantages of manual inspection and has a good development prospect in the liqui...
