Machine vision based on-line detection system and detection method thereof

Abstract

Being applicable to the technical field of display unit detection, the invention discloses a machine vision based on-line detection system and a detection method thereof. The machine vision based on-line detection system consists of a darkroom equipped machine body, which strides over a conveyer line, the conveyer line is used for conveying a display unit and loading the protection tooling of the display unit. The darkroom is internally provided with an imaging device, and is equipped with an overturning component for tunring over the display unit or the display unit and the protection tooling to make the display unit face the imaging device, the display unit is in connection with a terminal box, and the darkroom is internally provided with a butt joint butted with the terminal box. The machine vision based on-line detection method adopts the machine vision based on-line detection system. The machine vision based on-line detection system and the detection method provided by the invention can realize continuous production and detection, have no need to take the display unit from the production line, and have the advantages of high detection efficiency, good detection effect, and high detection automation degree.

Description

technical field [0001] The invention belongs to the technical field of display device detection, and in particular relates to a machine vision-based online detection system and a detection method thereof. Background technique [0002] In recent years, due to the good characteristics of lightness and thinness of LCD (Liquid Crystal Display), it has been used in most communication products (such as car navigation systems, mobile phones), consumer electronics (such as LCD TVs, cameras), instrument products and industrial products. In fields such as automation products, LCDs are used as control panels, and its application range is very wide, and the market has been constantly expanding. Since the entire LCD production process is long, and the size of the substrate is getting larger and larger, and the circuit size is becoming more and more precise, therefore, more stringent quality control is required in the production process of the LCD. But at present, in the LCD inspection p...

Problems solved by technology

In recent years, with the high-grade, large-scale, and internationalization of LCD screens, the requirements for inspection have become higher and higher, and the measurement method has also transitioned from random inspection to 100% full inspection. The inspection items have changed from simple to complex, and manual inspection can no longer meet the requirements. Such labor-intensive and complex precision requirements

[0003] However, the inspection system based on machine vision in the prior art generally needs to remove the display device from the production line, and then perform inspection separately, which has a low degree of automation and low detection efficiency.
