Backlight module detection equipment and detection method

Abstract

The invention discloses backlight module detection equipment and a backlight module detection method. The detection equipment comprises feeding production lines, a detection station, a manipulator and qualified and non-qualified production lines, wherein the feeding production lines used for providing to-be-detected backlight modules to the detection station, the detection station is arranged at one side of a material supply track and comprises a CCD detection device, a light source, a vacuum assembly and a detection work station, the vacuum assembly and the detection work station are fixed on the detection station, during operation, through arranging the CCD detection device, the vacuum module and a turning rotation disc, internal and external portions of the backlight modules are sequentially detected, after analysis on characteristic image values of the backlight modules is carried out through the CCD detection device, whether abnormality exists is determined, and the backlight modules can be disposed by a background control system through the manipulator to the corresponding qualified and non-qualified production lines. The detection equipment is advantaged in that internal and external detection on the backlight modules can be realized automatically, so whether the backlight modules are abnormal can be determined, detection efficiency is improved, a problem of easily-generated errors because of manual detection can be avoided, manpower cost is reduced, and production quality is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a detection device for a backlight module and a detection method thereof. Background technique [0002] On intelligent automation equipment, automation equipment or image detection technology is often used for product quality inspection. Using image positioning or image detection technology will inevitably use a camera, that is, a CCD detection device. In these high-precision intelligent applications, CCD The detection device must be fixed in some specific positions of the equipment in order to capture a clear and effective image. In the process of traditional backlight module processing, it is usually necessary to detect from different angles whether there are black and white spots and color differences inside the product, whether there are scratches and dust on the appearance, and in this inspection process, the operation fineness of the backlight module to be inspected Highe...

Problems solved by technology

In the process of traditional backlight module processing, it is usually necessary to detect from different angles whether there are black and white spots and color differences inside the product, whether there are scratches and dust on the appearance, and in this inspection process, the operation fineness of the backlight module to be inspected Higher requirements are put forward. Usually, the internal and external parts of the product are inspected manually. Due to the need for frequent observation of the backlight module, long-term use of the eyes will cause visual fatigue. Missed detection of qualified products, therefore, a device that can automatically detect the inside and outside of the backlight module should be designed to avoid the disadvantages of manual detection errors, reduce labor costs, and improve product quality
