Abstract
The utility model provides a gravure roller surface defect detection device, which comprises a linear LED (light-emitting diode) light source, a linear array CCD (charge coupled device) camera and an industrial personal computer. The linear array CCD camera is connected with the industrial personal computer by a Gigabit network card through signals. The detection device can be used for detecting surface defects of a gravure roller and has high detection accuracy and high speed, and real-time online detection can be achieved.
Description
Technical field
The utility model relates to detecting instrument, particularly a kind of gravure printing roller surface defect detection apparatus.
Background technology
Any defective on gravure printing roller surface all can be reflected on the pattern of printing, so definitely can not exist by defectiveness on the surface, the detection to the surface generally is by manually finding defective with eyes at present.Manually be difficult to long-time the sight and look into, the thing of omission often takes place, cause very big economic loss.
The utility model content
The purpose of this utility model is exactly in order to provide a kind of gravure printing roller surface defect detection apparatus.
To achieve these goals, the utility model has adopted following technical scheme: a kind of gravure printing roller surface defect detection apparatus, comprise wire led light source, linear array CCD camera and industrial computer, and linear array CCD camera links to each other with the industrial computer signal by PCI-Express.
Described linear array CCD camera is the STL-7400RCL camera, and it is that YF3528, enlargement ratio are the high resolving power of 0.5X, low distortion industrial lens that this camera is selected model for use.
The length of described wire led light source and the length of detected gravure printing roller are suitable.
Described wire led light source is selected the red LED linear light source for use.
Adopt pick-up unit of the present utility model to be used to detect the surface imperfection of gravure printing roller, the accuracy of detection height, speed is fast, and can realize that real-time online detects.
