Multi-camera transparent object defect detecting system

Abstract

The invention provides a multi-camera transparent object defect detecting system which comprises a hardware part and a software part. By taking a multi-camera transparent film optical defect detectingsystem as an example, a special linear array camera and a special surface array camera are adopted to realize adjustment in a Y-axis direction and a Z-axis direction, and detected defect types are increased; a transmission synchronous belt adopts a hollow-out design, so that influences, on an intermediate colloid detected part, of a supporting object are effectively avoided; a material receivingdevice adopts a joint way, and directly transmits materials to a material separating rotary plate after passing through a transmission synchronous belt, so that material receiving is smooth without another transmission, and thus, damages onto products are avoided; and a material collecting device adopts the material separating rotary plate to rotate an angle and products freely slide to sort qualified products and unqualified products, so that damages, on products, of mechanical vibration are avoided, sorting efficiency is improved, and time and labor cost are saved.

Description

technical field [0001] The present invention relates to the field of defect detection, in particular to a multi-camera defect detection system for transparent objects, taking a multi-camera transparent film optical glue defect detection system as an example. Background technique [0002] With the increasing demand for films in the international and domestic transparent film markets, the competition in the transparent film industry has become increasingly fierce. More and more manufacturers have begun to start production lines with faster production speeds in order to reduce costs and improve production efficiency. Benefiting from the rapid development of smartphones, tablet computers, and vehicle displays, optically transparent adhesives are widely used in the field of touch screens. In the touch screen, the optical transparent adhesive is mainly used for bonding ITO glass or ITO film to the panel. At present, there are more than 30 machine vision brands that have entered C...

Problems solved by technology

[0003] Since the product is prone to defects during the production process, taking the transparent film optical adhesive as an example, the surface of the transparent film optical adhesive is prone to defects such as bubbles, foreign objects, scratches, dirt, and indentations, so higher requirements are put forward for defect detection. At present, domestic enterprises still use manual detection of defects, and the detection efficiency is low. This method can no longer meet the detection of a large number of product defects, and uses a single camera to collect images to detect optical glue. Requirements, resulting in missed detection of defects. During the shooting process of the camera, due to the barrier of supports, such as the support of glass to the camera, and the defects of the glass itself, the defects in the collected images are inaccurate, resulting in false detection of defects, and the product is not received smoothly. Cause damage, qualified products and non-conforming products cause damage to products due to mechanical vibration during sorting, so the multi-camera defect detection system becomes an indispensable part of product defect detection
