Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] Such as figure 1 , figure 2 As shown, the present invention proposes a method and system for automatically searching pin positions applied to LCD white glass AOI testing, 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. Different images can be displayed on the display screen after the two kinds of pins are powered on. ...

Abstract

The present invention provides a method and system for automatically searching pins for LCD white glass AOI testing, comprising the steps of: connecting a power supply module to COM pins and SEG pins of LCD white glass; supplying power to each pin to generate multiple patterns, and photographing And record all the patterns and associate them with the corresponding pins; select an image and compare it with all the other images one by one, and divide the images into two categories according to the comparison results; distinguish COM pins and SEG pins according to the two types of images. It can realize the automatic search and correct judgment on the COM pin and SEG pin of the LCD white glass, and solve the defects of low efficiency in the process of manual connection judgment, excessive use of fixtures and difficult management.

Description

technical field [0001] The invention relates to the field of LCD detection equipment, in particular to a method and system for automatically searching pin positions for LCD white glass AOI testing. 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 Unlike the arrangement of SEG pins, it is not possible to accurately determine which pin is the COM pin (pin position) and which pin is the SEG pin (pin position) during use. [0003] The existing LCD white glass is used to identify the correct COM pin and SEG pin. Since there are many pin positions on the LCD glass, it is necessary to manually connect them one by one, and then detect and distinguish different pins. There are many fixtures used in this way, requiring maintenance and management, and the measurement ...
