Embodiment Construction

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the drawings as follows.

[0025] The present invention provides a measurement and debugging platform. Through the debugging platform according to the present invention, the detection device and the object to be tested can be conveniently placed in appropriate positions on the debugging platform, and the special structure of the debugging platform can be convenient and fast , Accurately adjust the position and parameters of the detection device, and then let the transmission image quality detection device trial run to detect the transmission image quality of the sheet material. For ease of description, the following embodiments mainly take the debugging platform for detecting the transmission image quality of sheet-shaped materials of the present invention as an example for description. However, it is obvious that the present invention can also be a debugging platform for qu...

Abstract

This invention discloses one test bench to test the slice material image transmission quality, on which one transmission test box is fixed with three black and white line array CCD vidicons, wherein the other end of the materials is the adhesive roller cylinder. The cylinder is driven by the variable motor and is connected to coder through one pair of gear with proportion as one to one; the cylinder inside is set with fixed fiber linear light source.

Description

Technical field [0001] The invention relates to a detection device, in particular to a debugging platform for detecting the transmission image quality of sheet materials. Background technique [0002] In order to increase the anti-counterfeiting capability of sheet materials such as banknotes, securities, stamps, and security papers, fluorescent images, infrared images, etc. are usually added to these sheet materials. Especially for banknotes, watermarks and security lines are also added, and some are also equipped with laser code holes. With the improvement of coinage technology, the accuracy of printing on the front and back of banknotes has also been greatly improved. In addition, paper defects are not allowed because high-quality paper-printed banknotes are difficult to imitate. In order to improve the anti-counterfeiting capability of banknotes and enable banknotes to have international circulation, it is urgent to ensure the high quality of banknotes. Strict inspection of t...
