Problems solved by technology

Manual inspection requires hundreds or even thousands of inspectors to carry out this process. It relies on the operator to stare at the backlight panel to see if there are defects on the film. Staring for a long time will cause eye fatigue and soreness, which will bring great harm to the factory. While increasing the huge labor cost and management cost, it has the characteristics of slow efficiency and high misidentification rate; while taking partial images cannot completely detect the production and printing status of the film, there is randomness, and it is prone to missed inspections, causing unqualified products to flow out
Existing detection methods are increasingly unable to meet the needs of production

Abstract

The invention discloses a printing film defect detection device. The device comprises a cross beam; at least one first bearing part arranged on the cross beam; at least one first mounting mechanism arranged on one side of the corresponding first bearing part; at least one camera assembly arranged on the corresponding first mounting mechanism; at least one second mounting mechanism arranged on the other side of the corresponding first bearing part; and a light source arranged on the at least one second mounting mechanism. The printing film defect detection device can realize the automation of printing film defect detection, can conveniently adjust the positions of a camera assembly and the light source through the first mounting mechanism and the second mounting mechanism, ensures that the line scanning camera is aligned with a bright spot irradiated on a film by the light source, guarantees the shooting stability and the image shooting quality, can be compatible with different films for surface defect detection, improves the working efficiency, and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of printing film production, in particular to a printing film defect detection device. Background technique [0002] With the development of the printing industry, the requirements for printing quality are getting higher and higher. When producing printed films, it is necessary to detect whether there are holes, wire drawing, creases, missing characters, ink dragging, crystal points, etc. on the surface of the printed film. At present, it is generally completed by manual detection or partial image detection. Manual inspection requires hundreds or even thousands of inspectors to carry out this process. It relies on the operator to stare at the backlight panel to see if there are defects on the film. Staring for a long time will cause eye fatigue and soreness, which will bring great harm to the factory. While increasing the huge labor cost and management cost, it has the characteristics of slow efficiency an...
