Device and method for visual detection of ink color changes and mechanical arm adjustment

Abstract

The invention discloses a device and a method for visual detection of ink color changes and mechanical arm adjustment. The device includes a main platform, a mechanical arm module arranged on the left side of the main platform, a visual detection CCD arranged on the right side of the main platform, and printing seats arranged on the middle part of the main platform. A mechanical arm communication wire is connected between the mechanical arm module and the visual detection CCD, and an ink roll control communication wire is connected between the visual detection CCD and the printing seats; the mechanical arm module is provided with a mechanical hand ink needle adjustment mechanism, the mechanical hand needle adjustment mechanism is connected with ink bucket and ink needle assemblies arranged on a plurality of printing seats, printing materials are printed with patterns through the printing seats, dynamic scanning is carried out by the visual detection CCD, and color gradation comparison is carried out with a standard specimen page originally stored in a computer. The device and the method for the visual detection of the ink color changes and the mechanical arm adjustment have the characteristics of improving the detection precision and the detection efficiency and reducing the cost, and are suitable for various printing machine types.

Description

technical field [0001] The invention relates to the field of visual detection, in particular to a high-precision, high-efficiency visual detection of ink color change and mechanical arm adjustment equipment and method. Background technique [0002] The current ink control system is based on the structure of the ink fountain. The ink needle inside adopts a tiny motor, which is placed inside to control the ink discharge type of the stroke area. When printing standard proofs or files, first notify the ink area of ​​each color in CIP3 or CIP4 format. Put the ink, and then take a sample to the color scanner for regular re-inspection, and fine-tune the slight data of the ink needle. [0003] Disadvantages of this method: [0004] 1. If one ink color has 15 ink areas, six colors need 15*6=90 electronic ink needles, and 90 sets of control units, the cost is very high; [0005] 2. The color needs to be adjusted by random inspection and confirmation, and cannot be monitored constant...

AI Technical Summary

Problems solved by technology

[0004] 1. If one ink color has 15 ink areas, six colors need 15*6=90 electronic ink needles, and 90 sets of control units, the cost is very high;

[0005] 2. The color needs to be adjusted by random inspection and confirmation, and cannot be monitored constantly;

[0006] 3. In the event of a single electronic ink needle failure, the area will not be able to control the use of ink, and the printing equipment will easily shut down due to the ink discharge system;

[0007] 4. E-ink needle maintenance parts are expensive;

[0008] 5. The slits of the electronic ink needle are not easy to clean, and it is easy to cause miscellaneous ink pollution;

[0009] 6. The electronic ink needle parts have strict tolerance requirements, and there may be problems with too large or too small gaps after maintenance and replacement, resulting in increased ink leakage factors
