Abstract
The utility model relates to a printing quality on-line detecting apparatus for Renminbi (RMB), which comprises a camera box hung at the lower part of an apron wheel of a printing production line, and an optical-electricity encoder is arranged on a wheel axle which is on the inflexion point of the printing production line. The camera box is provided with linear light sources. A signal output terminal of the optical-electricity encoder is connected with a camera by a signal cable. An image acquisition card is connected with the camera, a control host and an image processing card, and the image processing card is also connected with the control host. An output terminal of the control host is provided with a control cable connected with a printing device. The utility model has advantages of simple mechanical structure, cost reduction, homogeneous light source, homogeneous response of picture element and high distinguishability because the utility model adopts the linear array camera.
Description
The utility model relates to a kind of printed matter printing quality on-line measuring device, and particularly a kind of Renminbi is opened the printing quality on-line measuring device greatly.
At present, Renminbi prints the device that has the area array CCD digital camera that import is adopted in online detection.When big printed patterns of picked-up.Use area array CCD camera, have following defective:, just need powerful paper adsorbent equipment that whole absorption is stable 1) because paper can be followed shake in the high speed transport process; 2) area array CCD camera will improve one times of resolution, and camera picture dot number will increase by three times, and the camera cost increases greatly; 3) existing detection system can not detect safety line and watermark simultaneously.
The purpose of this utility model is: provide a kind of Renminbi to open the printing quality on-line measuring device greatly, and simple in structure, the resolution height, system cost is low.
The utility model is achieved in that a kind of Renminbi opens the printing quality on-line measuring device greatly, comprise the umbilical cable that videotapes case, photoelectric encoder, main control system, image collection card, image processing card and be connected to printing equipment, the described case that videotapes hangs on print stream waterline crawler belt bottom, photoelectric encoder is arranged on the wheel shaft at print stream waterline flex point place, videotape the case end face and have opening, be provided with line source and line array CCD gamma camera in the case, the signal output part of photoelectric encoder is connected on the gamma camera by signal cable; Image collection card links to each other with gamma camera, main control system and image processing card; The image processing card also links to each other with main control system; The main control system output terminal also is provided with the umbilical cable that is connected to printing equipment.
Described image collection card is connected by LVD30 million parallel 8 bit digital paths with gamma camera;
Described image collection card is crossed 200,000,000 CAB buses with the image processing cartoon and is connected;
Be connected by 133,000,000 pci buss between the main control system of narrating and image collection card and main control system and the image processing card;
Described videotaping also is provided with reflective mirror in the case.
The utility model is owing to adopt line-scan digital camera and coupled, send the photoelectric encoder of operational order to it, single line sensitization at one time, physical construction is simplified greatly, and the reduction system realizes cost, and single line sensitization realizes easily, light source is even, the picture dot response is even, and image quality is good, the resolution height.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, videotape the bottom that case 3 hangs on print stream waterline crawler belt 6, photoelectric encoder 5 is arranged on the wheel shaft at print stream waterline flex point place, videotapes and is provided with line source 1 and line array CCD gamma camera 4 in the case, and reflective mirror 7 also is arranged at and videotapes in the case.8 is gas blow pipe among the figure, and 9 is support.The signal output part of photoelectric encoder is connected on the gamma camera by signal cable; Image collection card A links to each other with gamma camera, main control system C and image processing card B; The image processing card also links to each other with main control system; The main control system output terminal also is provided with the umbilical cable that is connected to printing equipment D.Any big the Renminbi that finishes printing 2 that detects when needs is held in the month tooth 12 and is held in the month when videotaping the upper box part opening part, the line source direct projection is to below proal big the printing bank note of certain speed, reflective mirror reflexes to the image in irradiate light zone in the gamma camera, imaging is to 2048 picture dots of linear array CCD camera, then by high speed image capture card, and be transferred to image processing by the 200M high speed data bus and stick into line data and handle by main control system control.10 is the specification product holder among the figure, and 11 is the substandard product holder.The utility model is owing to adopt the high speed linear array CCD camera, and systemic resolution can reach 0.4mm * 0.4mm, and distortion is less than 1%; Owing to adopt photoelectric encoder to solve the collection stationary problem, thereby obtained the full width image of scanner distortion less than 0.05mm; Owing to adopt reflective mirror, solved the difficult problem that this verifying attachment is installed in the narrow space; Owing to adopt the linear array optical fiber source, improved light efficiency greatly, and provide cold light source to improve system reliability; Owing to adopt the special-purpose 200M data bus of image collection card and image processing card formation, arithmetic speed is up to 160M, and greatly reduces electromagnetic interference (EMI); Owing to adopt the semiclosed shooting case that has gas blow pipe, played the good dust-proof effect.
