Cigarette box appearance quality detection method based on CCD

Abstract

The invention provides a cigarette box appearance quality detection method based on a CCD. The cigarette box comprises the steps: firstly, adjusting parameters of a CCD industrial camera and a light source; ensuring that the CCD industrial camera can obtain sufficient exposure time and definition; taking pictures after adjustment; storing image parameters of cigarette boxes with appearance defectsinto a defected cigarette box database after taking the pictures; providing a query interface for users. Compared with an existing visual detection system, the cigarette box appearance quality detection method disclosed by the invention utilizes a machine vision algorithm to adjust the parameters of the CCD industrial camera and the light source, cigarette box images collected by the CCD industrial camera are ensured to meet detection requirements, unqualified cigarette box image parameters are stored to the defected cigarette box database, data support is provided for users to query and retrospect defected cigarette boxes, appearance detection accuracy of recyclable cigarette boxes is improved to a great extent, and quality and efficiency of a case filling and sealing machine are furtherimproved.

Description

technical field [0001] The invention relates to the field of cigarette case appearance detection in cigarette production, in particular to a CCD-based method for detecting the appearance quality of the cigarette case. Background technique [0002] Since the recyclable cigarette boxes go through multiple links in the recycling process before they are finally recycled on the machine, during this period it is easy to cause certain damage to the quality of the smoke boxes, which affects the efficiency of automated packaging to a certain extent. Will lead to a decline in packaging quality. In order to efficiently recycle the cigarette boxes and complete the production tasks with quality and quantity, correspondingly higher requirements are put forward for the quality inspection of the packing workshop and logistics department, and the visual inspection system has also emerged as the times require. [0003] The existing visual inspection system includes a background computer inte...

Problems solved by technology

[0004] The visual inspection system uses the visual interface and the cooperation of the CCD industrial camera to detect the smoke box with appearance quality problems. However, due to the requirements of production efficiency, the exposure time of the CCD industrial camera is very short when collecting the appearance image of the smoke box, which leads to There are certain errors in the appearance inspection of the smoke box. In view of the above situation, it is necessary to develop a CCD-based inspection method for the appearance quality of the smoke box as a check measure for the quality of the smoke box to avoid quality problems caused by secondary damage to the smoke box.
