Embodiment Construction

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

[0025] The invention provides a measurement and debugging platform, through the debugging platform according to the invention, the detection device and the detected object can be conveniently placed on the appropriate position on the debugging platform, and through the special structure of the debugging platform, it can be conveniently and quickly 1. Accurately adjust the position and parameters of the detection device, and then make the transmission image quality detection device test run to detect the transmission image quality of the sheet material. For the convenience of description, the following embodiments mainly take the debugging platform for detecting the quality of the transmitted image of a sheet material as an example for illustration. However, it is obvious that the present invention can also be used as a debugging station for s...

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 quality of a transmission image of a sheet material. Background technique [0002] In order to increase the anti-counterfeiting capabilities of banknotes, securities, stamps, security paper and other sheet materials, fluorescent images, infrared images, etc. are usually added to these sheet materials. Especially for banknotes, watermarks and security threads are added, and some are also provided with laser coding holes. With the improvement of coinage technology, the printing accuracy of the front and back of banknotes has also been greatly improved. In addition, paper defects are not allowed, because banknotes printed on high-quality paper are difficult to imitate. In order to improve the anti-counterfeiting ability of banknotes and make banknotes have the ability of international circulation, it is urgent to ensure the high quality of banknotes, and ...
