Glass alignment electrical control system for plain glass optical inspection machine

Abstract

The invention discloses a glass alignment electrical control system for a plain glass optical inspection machine, and the system comprises a man-machine operation interface which is used for enablingan operator to interact with equipment and achieving the visualization of a control process; a main control module which is in communication connection with the man-machine operation interface and isused for writing and executing a program; a motion control module which is connected to the main control module and translates the motion control process into a recognizable pulse signal; a servo driving module which is connected with the motion control module and converts the pulse signal into a voltage signal after receiving the pulse signal; an operation panel connected with the man-machine operation interface, peripheral equipment connected with the motion control module, a servo motor connected to the servo driving module, and a motor encoder which connected to the servo motor and used for feeding back the position and speed to the servo driving module. The programming is more convenient, the operation is simpler, and the applicability is wide; the automatic production operation can be achieved, the glass detection yield of automatic optical inspection equipment can be improved, the reliability of the equipment is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a glass guiding electrical control system for plain glass optical inspection machines. Background technique [0002] The liquid crystal panel production industry still manually inspects defects such as scratches and chipping on the glass during the initial production process of plain glass substrates. The use of optical inspection equipment (AOI) has greatly solved these problems. [0003] Since the equipment of most glass manufacturing enterprises in the production and cutting of plain glass is mostly old and has a high failure rate, some irregular phenomena such as tilting of the incoming material direction of the glass after the end of the previous process often occur. The reason for this is It is also more complex and changeable, such as how much glass cleaning fluid will cause the glass to tilt. [0004] Since the machine vision software of automatic optical ins...

Problems solved by technology

[0003] Since the equipment of most glass manufacturing enterprises in the production and cutting of plain glass is mostly old and has a high failure rate, some irregular phenomena such as tilting of the incoming material direction of the glass after the end of the previous process often occur. The reason for this is It is also more complex and changeable, such as the amount of glass cleaning fluid used will cause the glass to tilt

[0004] Since the machine vision software of automatic optical inspection equipment (AOI) has a limited rotation angle for automatic deflection correction of image acquisition, excessive glass deflection angles will reduce the yield of automatic optical inspection equipment.
