Problems solved by technology

For this reason, in the subsequent process, there is a step in which the inspector performs the final inspection on the product again, and this visual inspection operation has the problem of requiring a lot of cost and time.
[0005] In addition, in the prior art, since only the defect occurrence rate information using only the number of defects measured in the coil can be obtained, there is a problem that the possibility of missing defects (that is, the defect is not marked) is not taken into account.

Abstract

The invention provides a polarizing film roll quality judging system and method thereof. According to the system and the method, the time and the cost for additional detections can be reduced. Meanwhile, coils of higher defect missing rate can also be automatically discriminated. In one embodiment of the invention, the important information of the roll quality based on the detection result data acquired by an optical detector is transmitted to subsequent steps, so that the early warning system function for unqualified coils is realized. Meanwhile, different processes are constructed according to coils of different qualities in subsequent steps.

Description

technical field [0001] The invention relates to a quality judging system and method for a polarizing film coil, in particular to a system and a method for judging the quality of a polarizing film coil using the detection result data of an automatic optical detection machine. Background technique [0002] A manufacturer of polarizing film used as an LCD optical material, in order to detect high-speed production products in real time, uses an in-line (IN-LINE) automatic optical inspection system (Automated Optical Inspection system, hereinafter referred to as an automatic optical inspection machine) . Generally speaking, the inline automatic optical inspection machine can discard the marked parts in the subsequent process by marking the color or marking the barcode on the position where the defect occurs, or perform additional inspection on such parts. [0003] However, i) when the above-mentioned defects are continuously and intensively generated at a specific time point, or...
