Description
Technical field
The present invention relates to tobacco manufacture fields, relate in particular to a kind of photoelectric detecting method of tobacco product.
Background technique
Representative one of of the quick-fried pearl cigarette as cigarette category innovation and development, because its unique advantage gradually show it is powerful
Growth and good development prospect, at home and abroad tobacco market causes extensive concern.It is interior after quick-fried integument is pinched brokenly
The liquid spice in portion overflows, and assigns the unique fragrance of cigarette, and consumer is made to obtain different suction experience.Due to quick-fried pearl filter stick
During production and processing and packed and transported, the unqualified feelings such as internal quick-fried pearl easily appearance position offset, missing and breakage
Condition, and then the quality of quick-fried pearl cigarette is had an impact, thus we it is necessary to carry out quality testing to quick-fried pearl filter stick.
The quality testing of current quick-fried pearl filter stick relies primarily on manual removal method, lamp box method and microwave method and is detected.Manually
Stripping method is that destructive detection, large labor intensity, low efficiency are carried out to sample；Lamp box method utilizes strong backlight illumination filter stick, then
With eye-observation, it is be easy to cause eye fatigue, is difficult to complete large batch of Detection task in the short time；Microwave method is to transport at present
With widest, this method can be realized the non-destructive testing of sample, but microwave equipment price is relatively high, microwave cavity etc.
The maintenance cost of critical component is high, and detection speed is still unable to satisfy online production demand.Patent publication No. in the prior art
Are as follows: disclose a kind of quick-fried pearl cigarette filter quality detection device in the patent of CN 207730680U, specially image capture module,
Controller and application module；Described image acquisition module includes CCD line-scan digital camera, point light source and encoder, for shooting quick-fried pearl
Cigarette filter complete image；The controller includes the vision algorithm processing platform based on side to detection instrument, for according to image
The image recognition and the detection quick-fried pearl defect of cigarette filter stick of acquisition module acquisition；The application module includes display, for showing
With the quick-fried pearl cigarette filter image information of storage and detection data；The CCD line-scan digital camera, point light source and encoder respectively with control
Device connection, controller are connect with display.The utility model utilizes the Image Acquisition and identification technology of view-based access control model algorithm, energy
It effectively detects the quick-fried pearl defect of cigarette filter stick, and the removing filter-stick of quick-fried pearl defect will be present, but it carries out quick-fried pearl by image
State-detection, has interference, and testing result is undesirable.
Therefore, a kind of convenience, economy are needed and quickly for effective detection method of quick-fried pearl in quick-fried pearl filter stick.
Summary of the invention
Based on this, the object of the present invention is to provide a kind of convenience, economy and quickly for the light of quick-fried pearl in quick-fried pearl filter stick
Electric detection method.This method uses optoelectronic device, is irradiated from quick-fried pearl filter stick side, and the other side receives the light for penetrating filter stick
Signal judges that the missing of quick-fried pearl in quick-fried pearl filter stick has nil case according to the attenuation of light signal strength.
Specifically, the present invention provides the following technical solutions:
The photoelectric detecting method of quick-fried pearl in a kind of quick-fried pearl filter stick, which comprises the following steps:
(1) photoelectric detection system is opened, optical path is adjusted；
(2) mobile quick-fried pearl filter stick and optical path are perpendicular through photoelectric detection system；
(3) state of quick-fried pearl in quick-fried pearl filter stick is judged according to the optical signal power through filter stick；
(4) the attenuated optical signal difference generated when being blocked using filter stick by optical path sets light according to different product
Signal strength threshold is A value, judges the state of quick-fried pearl filter stick with the variation of A value, and realizes the numeration of quick-fried pearl addition in filter stick.
(5) light variable signal and PC are realized that record communicates in real time, available quick-fried pearl filter stick passes through photoelectricity when optical path
Signal curve.Using peak value in curve, there is nil cases to reflect the presence or absence of quick-fried pearl situation, corresponding length occurs using peak value
Degree variation reflects the position offset of quick-fried pearl, and the breakage of quick-fried pearl is reflected using the variable quantity of peak value.
Preferably, the shape of quick-fried pearl in quick-fried pearl filter stick is judged in the step (3) according to the optical signal power through filter stick
State: tow partial light permeability is relatively preferable, and the optical signal that receiving end obtains is stronger；When filter stick is mobile, optical signal is hidden by quick-fried pearl
Gear, the optical signal that receiving end obtains at this time will weaken.
Compared with the prior art, technical solution of the present invention bring the utility model has the advantages that
(1) technical solution of the present invention provides a kind of detection side using photoelectric method to quick-fried pearl state in quick-fried pearl filter stick
Method, this method can accurately identify the missing breakage state of quick-fried pearl in quick-fried pearl filter stick, and can accurately measure the position of quick-fried pearl；
(2) technical solution of the present invention is economic and practical, easy to operate, method is reliable, convenient and efficient, is conducive to promote fortune
With.
