Description
Technical field
This utility model relates to a kind of online imaging system of leaflet, and a kind of leaflet based on area array cameras exists
Line imaging system, and a kind of online formation method of leaflet based on area array cameras.
Background technology
Advanced printer, its print speed printing speed has generally reached 200 ms/min, the highest.Give leaflet at high speed
Online quality control brings challenge greatly, is embodied in:
First, in the case of high speed printing, the collection difficulty of image；
Secondly, in the case of high speed printing, quality problems once occur, it will be continuous print, large-area scrap；
Furthermore, printer needs the most accurate tension force to control so that cannot sample leaflet in printing process；
Finally, unreeling → print → printing process of rolling in, if product cannot be carried out effective quality-monitoring,
Once there is printing issues, then all of leaflet all will be scrapped.
At present, existing leaflet on-line checking scheme has following three kinds:
1, quality testing based on stroboscopic instrument；By synchronizing stroboscope and printer, when leaflet to ad-hoc location
(such as each product length) gives the shortest and rapid flash of light, and operator directly observe printed matter surface, can be even
Seeing static printing surface during continuous printing, the program realizes simple, and low cost however it is necessary that quality assurance person possesses abundant
Experience, there is problems in that simultaneously
1.1, quality assurance person must pass through direct visual perception, in the case of group flashing light, arises that in the short time
Visual fatigue；
1.2, provisional imaging, it is impossible to comprehensively observe；
1.3, being difficult to, due to stroboscope and printer, the synchronization accomplished truly, both are constantly present certain mistake
Difference, the printing surface that therefore quality assurance person is observed visually can produce continuous print drift, it is impossible to observes details.
2, imaging system based on line-scan digital camera, the program is the use line-scan digital camera image capture device as leaflet,
By installing encoder on the printer, gather continuous print pixel column, finally by capture card, image is spliced, and
Show on display.The program there is problems in that
2.1, equipment cost is high, and the line-scan digital camera price of 4000 pixels is about 3-4 ten thousand yuan；
2.2, imaging area is little, 4000 pixels, if according to quality control requirement 0.05 millimeter, its area only has 4 centimetres；
2.3, under high speed printing, precision is unable to reach requirement, exists according to the line-scan digital camera of 20000 row mentioned before/second
When shooting the leaflet of 200 ms/min, on each pixel precision correspondence leaflet 0.167 millimeter, 0.05 cannot be met far away
The quality control requirement of millimeter (5).
3, coordinate the imaging system of flash of light control based on area array cameras, the program there is problems in that
3.1, owing to the shutter speed of usual area array cameras was at about 1/1000th seconds, few mm professional camera special can reach
1/10000th seconds, according to 200 ms/min, the print speed printing speed of i.e. 3.3 meter per seconds, the most at last the shutter speed of 1/10000th seconds
Degree, in the time that shutter is opened, printing paper has created the displacement of 0.33 millimeter, cannot meet far away the matter of 0.05 millimeter
Amount control accuracy；Exposed by the flash time of flasher (such as flash lamp), during its flash of light of conventional flash unit simultaneously
Between at 1/1000 to 1/3000 second, an ibid description, such time of exposure cannot meet requirement；In recent years, the sudden strain of a muscle of specialty
Light modulation can reach 1/10000 second, and even 1/20000 second, such flash unit was expensive, and is nominally 1/
The flash unit of one of 20000 seconds, refers to that its brightness exceedes after maximum brightness 50% to luminance-reduction to maximum brightness in fact
This time interval before 50%, but in actual application, brightness typically surpassing during this period of time less than maximum brightness 50%
Cross 50% twice during this period of time, flash of light during this period of time also can imaging on the sensor of area array cameras, thus cause photograph mould
Stick with paste；As certain brand flash fire persistent period is expressed as flash duration t=0.5:1/2000S, this flash lamp is true
Positive fluorescent lifetime is 3/2000S, about at 1/700S.Cause, when leaflet is shot by above-mentioned area array cameras, due to print
The high-speed motion of brush product, imaging is the fuzzyyest；
3.2, due to the bad assurance of aperture time, it is impossible to the position of the leaflet that is taken is positioned, a lot of weight is caused
Reset the candid photograph put, and strengthens the difficulty of quality control.
