Embodiment Construction

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0047] Such as figure 1 , figure 2 As shown, the present invention provides an automatic pin search method and system for AOI testing of LCD white glass, including the following steps:

[0048] Step S100, the power supply module is connected to the COM pin and the SEG pin of the LCD white glass.

[0049] In the steps of this implementation, the LCD white glass is powered by the power supply module. The LCD white glass has two types of pins: COM pin and SEG pin. The two pins can be energized to display different images on the display. For ease of understanding, the COM pin can be un...

Abstract

The invention provides an automatic pin position searching method and system applied to an LCD white glass AOI test. The method comprises the steps of: connecting a power supply module with a COM pin and an SEG pin of the LCD white glass; respectively supplying power to each pin to generate a plurality of patterns, shooting and recording all the patterns, and associating the patterns with the corresponding pins; selecting an image to be compared with all the other images one by one, and dividing the images into two types according to the comparison result; and distinguishing a COM pin and an SEG pin according to the two types of images. The method can realize automatic search and correct judgment of the COM pin and the SEG pin of the LCD white glass, and overcomes the defects of low efficiency, excessive use of clamps and difficult management in the process of manual connection judgment.

Description

Technical field [0001] The invention relates to the field of LCD detection equipment, and in particular to an automatic pin search method and system applied to AOI testing of LCD white glass. Background technique [0002] LCD white glass is a component used for display in electronic equipment, including a glass screen for display and pins for connection. The pins are composed of COM pins and SEG pins. Due to the variety of LCD glass specifications, COM pins Different from the arrangement of the SEG pin, it cannot be accurately judged which pin is the COM pin (pin position) and which pin is the SEG pin (pin position). [0003] The existing LCD white glass is to distinguish the correct COM pin and SEG pin. Because there are many pins on the LCD glass, it is necessary to manually connect them one by one, and then detect the different pins. There are many jigs used in this way, which requires maintenance and management, and the measurement efficiency of workers is low. [0004] Therefo...
