Description
Technical field
The utility model relates to image false distinguishing fields, and in particular to a kind of contact type image biography with adhesive tape detection function
Sensor.
Background technique
In banknote image collection process, the lens in contact-type image sensor can only receive to send perpendicular to transparent panel
Light, if encountering the bank note for being pasted with adhesive tape, since adhesive tape is similar to transparent glass, mirror-reflection is very strong,
Diffusing reflection is weaker, and the vertical light that lens receive is relatively fewer, and the optical signal for receiving contact-type image sensor is limited, causes to connect
Touch imaging sensor is insensitive to adhesive tape, can not detect.Existing solution is contact-type image sensor inspection
After survey, setting is exclusively used in the mould group of detection adhesive tape in sending paper money channel, but in this case to the structure angle of cash inspecting machine component
Degree requires height, and because the external factors influences such as the easy dust stratification of mould group, structural member deformation cause the mould group service life ofer short duration, function reduction
Fastly, and the mould group added, the volume of false distinguishing component is not only increased, production cost is further increased.
Notification number is 104580808 B of CN, entitled contact-type image sensor, and the sensor is by lens and scanning surface
Placement at an angle, though the mirror-reflection light on part to be scanned can be received, so that solving adhesive tape can not identify
The problem of.But encountering has the bank note of fold to pass through, and just will appear the situation of bright and dark light unevenness, causes imaging effect bad, because
This is in practical banknote false distinguishing and is not suitable for, and operability is too poor.
Notification number is 201927100 U of CN, a kind of entitled contact-type linear array sensor, which can be in glue
Band paper surface forms total reflection, forms highlight regions on the image of formation, to achieve the purpose that identify adhesive tape, but the party
Only one receiver of case, mirror reflection effect is preferable, and diffusing reflection is then insufficient, imaging effect and bad in actual mechanical process.
It follows that not finding realistic plan also in actual operation to improve contact-type image sensor.
Summary of the invention
In view of the deficienciess of the prior art, the utility model provide a kind of strong operability, structure is simple, band
The contact-type image sensor of adhesive tape detection function.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solutions:
A kind of contact-type image sensor with adhesive tape detection function comprising shell, shell is interior to be equipped with lens, lens
Side set the light source with light guide, be transparent panel above lens, the lower section of lens is equipped with wiring board, and wiring board is equipped with light
Electric conversion chip, the utility model are a newly-increased photosensitive elements on the other side of the lens, and photosensitive element is connected with wiring board, photosensitive
The surrounding of element sets the lamp guide of a hollow cylinder, so that photosensitive element only receives the light of fixed-direction.Light source and transparent panel
It is placed at fixed angle, light source is irradiated on transparent panel, and photosensitive element is just arranged on the reflection direction of light source.Light source with it is transparent
The fixed angle of plate is between 25 to 70 degree.
The illumination that light source issues is mapped on adhesive tape, returns photosensitive element, photosensitive member through adhesive tape mirror-reflection
Received optical signal is converted into electric signal by part, is exported outward as image information.
The invention has the following advantages:
This programme eliminates the mould group for examining adhesive tape in original currency counting and detecting machine structural member, saves material and sky
Between, and because contact-type image sensor is produced under dustfree environment, angle is designed before need to only installing, not only installation side
Just, the external interferences such as dust, malformation are also eliminated, the service life is longer, and function is more stable.
Photosensitive element is arranged on the reflection direction of light source, and photosensitive element only receives the light of fixed-direction reflection, so that
Photosensitive element receives the optical signal more complete and accurate of adhesive tape mirror-reflection, and the image information of collection is just more comprehensively.
Using two sets of reception devices of lens and photosensitive element, the stabilization of bank note imaging not only ensure that, but also compensate for former contact
Formula imaging sensor is insensitive to adhesive tape, the problem of can not detected, and strong operability is suitble to be widely used.
Detailed description of the invention
Fig. 1 contact-type image sensor side cut away view；
Specific embodiment:
The utility model is further described with reference to the accompanying drawing.
See Fig. 1, a kind of contact-type image sensor with adhesive tape detection function comprising shell 1 is equipped in shell 1
Lens 2, the side of lens 2 set the light source 3 with light guide, and the top of lens 2 is transparent panel 4, and the lower section of lens 2 is equipped with wiring board
5, wiring board 5 is equipped with photoelectric conversion chip 6.Circuit is equipped with inside photoelectric conversion chip 6, photoelectric conversion chip 6 is by optical signal
It is converted into electric signal, is exported outward as image information, this is the structure of existing contact-type image sensor.
The utility model is characterized in that increasing a photosensitive element 7, photosensitive element 7 and wiring board 5 newly in the other side of lens 3
It is connected, the surrounding of photosensitive element 7 sets a cylindrical lamp guide 8, and lamp guide 8 ensure that photosensitive element 7 only receives fixed-direction
Light.Light source 3 is placed with transparent panel 4 at fixed angle, and light source 3 is irradiated on transparent panel 4, and photosensitive element 7 is just arranged in light source 3
