Online visual inspection system for facial mask production line

Abstract

The invention discloses an online visual inspection system for a facial mask production line. The online visual inspection system comprises an image acquisition unit, an image processing unit and a PLC. The image acquisition unit comprises a light source, a lens, a camera and an image acquisition card. The light source comprises an LED lamp source, a fluorescent lamp source and a laser ray source.The camera is matched with the LED lamp source, the fluorescent lamp source and the laser ray source to acquire corresponding images. The camera and the LED lamp source are used in cooperation to acquire the outline and surface of a facial mask. Whether flaws exist on the outline and surface of the facial mask or not is judged by comparing the facial mask with a standard facial mask through the image processing unit. The facial mask is collected through cooperation of the camera and the fluorescent lamp source. Whether the facial mask contains a fluorescent agent or not is judged by comparingthe facial mask with the standard facial mask through the image processing unit. The camera and the laser ray source are used in cooperation to collect the status image of laser rays on the facial mask. Whether the facial mask is torn or not is judged by comparing the facial mask with the standard facial mask through the image processing unit.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to an online visual detection system used in a facial mask production line. Background technique [0002] Traditional mask cutting mostly adopts manual cutting, machine punching and cutting, and two vacuum nozzles to open the bag, which is inefficient, and the traditional mask has many steps from cutting to bagging, which wastes time and labor costs and the process The disinfection requirements are difficult to control; in order to solve this technical problem, the Chinese patent application publication number CN108100737A discloses a fully automatic mask production line, by setting the mask unwinding device, the materials of the mask film unwinding device are superimposed by the deviation correction device Enter the first roller die-cutting machine to form the mask structure on the first belt conveying line, set the mask packaging bag unwinding device to connect with ...

[0002] Traditional mask cutting mostly adopts manual cutting, machine punching and cutting, and two vacuum nozzles to open the bag, which is inefficient, and the traditional mask has many steps from cutting to bagging, which wastes time and labor costs. It is difficult to control the disinfection requirements; in order to solve this technical problem, the Chinese patent application publication number CN108100737A discloses a fully automatic mask production line, by setting the mask unwinding device, the materials of the mask film unwinding device are superimposed by the deviation correction device Enter the first roller die-cutting machine to form the mask structure on the first belt conveying line, set the mask packaging bag unwinding device and connect with the roller die-cutting machine to form the mask packaging bag on the second belt conveying line, the mask structure passes through the mask left and right The folding seat is folded left and right to form a folded mask structure, and the mask packaging bag is opened after entering the bag opening device; and a cylinder telescopic arm is set above the first belt conveying line so that the folded mask structure falls into the In the mask packaging bag, the mask packaging bag on the second belt transmission line is continuously opened by the rotary vacuum bag opening device, so as to realize the functions of fast cutting, fast folding and fast bagging of the mask. At the same time, the production line is equipped with AGV trolley and automatic The splicing device realizes uninterrupted feeding; however, this patent cannot detect the outer contour defects of the mask, the surface defects of the mask, the tearing of the mask, and whether the mask contains fluorescent agents, etc., which cannot meet the quality requirements of the mask
