Abstract

The invention provides a detection method of a full-automatic background module detector. The detection method includes: step S1, receiving incoming material information and correcting through an optical fiber sensing mechanism; step S2, grabbing corrected incoming materials to a jig; step S3, adopting a film stripping mechanism for carrying out film stripping action, and conveying to a laminationcorrection position through a film transport line; step S4, starting signal acquisition according to detection signals, namely acquiring images, positioning, calculating, outputting results and recording data; step S5, receiving product information through the optical fiber sensing mechanism, laminating a protective film at the correction position to a product, and detecting; step S6, performingdistinguished discharging according to detection results. The detection method of the full-automatic background module detector has advantages that existing manual lamp detection can be replaced withthe method, and high detection precision and high detection efficiency are realized.

Description

technical field [0001] The invention relates to the field of detection machines, in particular to a detection method of a fully automatic backlight module detection machine. Background technique [0002] Backlight module (Back light module) is one of the key components of liquid crystal display panel (LCD panel). Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and evenly distributed light source to make it work normally. Display the image. LCD panels are now widely used in electronic products with growth potential such as monitors, notebook computers, digital cameras, and projectors. Therefore, the demand for backlight modules and related components continues to grow. Stimulated by the low price of panels , and the demand for large-size panels such as notebook computers and LCD monitors is the largest, which is the main source of growth in the demand for backlight modules. [0003] At present, the...
