Referring to Fig. 2, the structural schematic diagram of the two-sided COF automatic optical detection device of winding of the invention is shown.A kind of volume
With two-sided COF automatic optical detection device, including detection roller 1, the detection roller set gradually along product circulation direction
2 210, the upside of detection roller 1 is provided with several CCD cameras 1, and the downside of detection roller 2 210 is provided with several
CCD camera 2 230, such as Fig. 2, product 240 to be detected is successively layed in the upper surface of detection roller 1, detection roller 2 210
Lower surface, when being detected, detection roller 1, detection roller 2 210 it is static, CCD camera 1, CCD camera 2 230
Work, is completed at the same time the detection work for treating 240 two detection faces of testing product.
In other embodiments of the invention, CCD camera 1 is set to the downside of detection roller 1, CCD camera two
230 are set to the upside of detection roller 230, and product 240 to be detected is layed in the lower surface of detection roller 1, detection roller two
210 upper surface.
It is noted that the circumferencial direction that several CCD cameras 1 are edge detection rollers 1 is uniformly arranged, and several
The sum of field angle of CCD camera 1 is greater than the size of the breadth of product 240 to be detected, i.e., the view of several CCD cameras 1
The sum of rink corner is greater than the size that product 240 to be detected is layed in the part of detection detection roller 1, similarly, several CCD cameras
2 230 be to be uniformly arranged along the circumferencial direction for detecting roller 2 210, and the sum of the field angle of several CCD cameras 2 230 is greater than
Product 240 to be detected is layed in the size of detection roller 2 210.For detecting roller 1, if product to be detected 240
Detection effective coverage is 140mm, and the allocation plan of CCD camera is as follows, resolution 1.5um/Pixel, 6 16K cameras, if then
The sum of the field angle of dry CCD camera 1 is 1.5*16*6=144mm, is met the requirements.
Such as Fig. 3, the side for detecting roller 1 is equipped with several suckers 1, and several suckers 1 are along detection roller
One 200 circumferencial direction and axis direction is uniformly distributed, and is additionally provided on the end face of detection roller 1 and is vacuumized hole 1,
It vacuumizes hole 1 to be connected to several suckers 1, be connect by vacuum evacuation device with hole 1 is vacuumized, can make to detect

With continued reference to Fig. 2, further, along product circulation direction, one 200 front of detection roller, front side roller 1
Between detection roller 2 210, detection 210 rear of roller is equipped with several guide pulleys 250, and along product circulation direction, if
Dry guide pulley 250, detection roller 1, detection roller 2 210 successively up and down is staggered, thus detect roller 1 with
Shape has angle between guide roller 250 before and after it, detects between roller 2 210 and guide roller 250 before and after it
Shape has angle.
Such as Fig. 4, the present invention also provides a kind of two-sided COF automatic optical detection method of winding, detailed process is as follows:
Several CCD cameras are arranged in the above/below of detection roller one in S1, setting detection roller one, detection roller two
One, several CCD cameras two are set in the lower section of detection roller two/top, are laid on detection roller one, detection roller two to be checked
Product is surveyed, product to be detected is located at detection roller one towards the surface of CCD camera one and detects roller two towards CCD camera two
Surface on;
In order to guarantee the planarization and fitting fixing of product to be detected, vacuum evacuation device connecting detection roller one is used
Vacuumize hole one and detect roller two and vacuumize hole two, and carry out vacuumize process, keep the product to be detected firm and flat
Whole is fitted in detection roller one, detects on roller two.
Preferably, along product circulation direction along, detection roller one front, detection roller one and detection roller two it
Between, the rear of detection roller two guide pulley is set, product to be detected be successively layed in detection roller one front guide pulley,
It detects roller one, detect on the guide pulley at one rear of roller, so that product to be detected is in the position for corresponding to detection roller one
Place's shape has angle, and similarly, product to be detected also will form an angle corresponding to detection roller two.
S2, CCD camera one, CCD camera two work, and two detection faces for treating testing product are detected, meanwhile, detection
Roller one, detection roller two rotate, and drive product to be detected mobile.
Preferably, vacuum evacuation device works, and makes product to be detected is firm be fitted in detection roller one, detect on roller two,
And the angle formed using detection roller one and guide pulley, the part that product to be detected is sent out can be detached from the suction of detection roller one
It is attached, and product infeed section to be detected can be then adsorbed, and detect the working principle at roller two and the work at detection roller one
Mode is identical, so, it is ensured that while absorption, product to be detected can continue mobile to circulation direction.
It is to be illustrated to what preferable implementation of the invention carried out, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
