Embodiment Construction

[0027] figure 1 An imaging device according to one embodiment of the present invention is shown. Such as figure 1 As shown, the imaging device includes a diffuse illumination light source 1 and an image acquisition device 2 . In this embodiment, the diffuse illumination light source 1 includes several LED light sources 3 and diffuse reflection arcs 4 . Optionally, the imaging device further includes a reflector 5 for turning back the collection light path of the image collection device, so that the imaging device of the present invention is more compact.

[0028] In this embodiment, the diffuse reflection arc 4 is semi-cylindrical, and the inner surface of the semi-cylindrical diffuse reflection arc 4 is coated with a material with high diffuse reflectance. For example, the inner surface of the diffuse reflection arc 4 is sprayed with a material mixed with barium sulfate, latex and water. Those skilled in the art should understand that although the LED light source and the...

Abstract

The invention provides imaging equipment for a laser printed product quality detection system and the corresponding detection system. The imaging equipment comprises a diffused illumination light source and an image acquisition device, wherein the diffused illumination light source is used for providing diffused light to a detected product; the image acquisition device is used for performing image acquisition on the detected product or a mirror image of the detected product at a predetermined tilt angle. The imaging equipment can be used for better imaging a printed pattern obtained by performing processes of gold blocking, belling and the like on a laser product, so that the corresponding detection system can be used for conveniently detecting the production quality problems of the processes based on an obtained image; the imaging equipment is especially suitable for performing imaging analysis on concave-convex information of the printed product.

Description

technical field [0001] The invention relates to the field of quality inspection, in particular to an imaging device used in a laser print quality inspection system. Background technique [0002] In recent years, with the continuous advancement of technology and the increasing abundance of materials, in order to enhance the visual effect and increase the added value of products, high-end printed matter often uses various types of laser paper and laser film as printing materials. More complex additional processes such as bronzing and embossing will be added. [0003] The automatic printing quality inspection technology based on machine vision, with its advantages of high speed, stability, and all-weather operation, effectively avoids missed inspections and wrong inspections caused by factors such as individual differences and fatigue in traditional manual visual inspection methods, and can It has become an inevitable trend in the development of the industry to solve the probl...
