Description

A kind of color optical fiber automatic checkout system

Technical field

A kind of color optical fiber automatic checkout system is the utility model is related to, belongs to detecting system technical field.

Background technology

Color discrimination system currently on the market has several drawbacks in that：

First, more high-precision color detection, its reaction speed is very slow, can be used only in the non-on-line checking in laboratory.

Two and other online high speed color sensors, its accuracy of detection are low, it is impossible to used in high-precision trapping printing or On the auto color sorting system of high speed.

3rd, the higher color sensor of external precision, all employs integral type detection, and size is very big, is not suitable for peace The place small mounted in station.

4th, former all color sensors are all shone respectively using tri- LED of RGB, for simulating white light, but it is this white Just false exposure, its frequency spectrum only have tri- kinds of colors of RGB, without frequency spectrums such as purple, yellow, cause purple, yellow and ash The muted colors such as color are unable to stability monitoring.

5th, conventional color sensor can only be close to the monitoring of 10 millimeter of object.

Utility model content

In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of automatic detection system of color optical fiber System.

A kind of color optical fiber automatic checkout system of the utility model, it includes host, fibre-optical probe, white light LEDs, RGB Three tunnel reception pipes, optical fiber；White light LEDs, tri- tunnel reception pipes of RGB are provided with the host, the white light LEDs, tri- tunnels of RGB receive Guan Jun is connected by optical fiber with fibre-optical probe, and the front end of the fibre-optical probe is provided with 10mm aspherical glass lens.

Compared with prior art, the beneficial effects of the utility model are：Energy stability monitoring, and be easily installed, it may exit off More than object 60MM is monitored, while adjusts probe lens and fiber position, it is possible to achieve big-and-middle small light spot is freely adjusted, can To detect planar object, small-sized punctiform object etc..

Embodiment

To make the objectives, technical solutions and advantages of the present invention clearer, below by showing in attached drawing Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality With new scope.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily mixing Confuse the concept of the utility model.

As shown in Figures 1 to 4, present embodiment uses following technical scheme：It include host 1, fibre-optical probe 2, White light LEDs 3, tri- tunnel reception pipes 4 of RGB, optical fiber 5；White light LEDs 3, tri- tunnel reception pipes 4 of RGB are provided with the host 1, it is described white Tri- tunnel reception pipe 4 of light LED3, RGB is connected by optical fiber 5 with fibre-optical probe 2, and the front end of the fibre-optical probe 2 is provided with 10mm Aspherical glass lens 2a.

The operation principle of present embodiment is：Light source is used as using white light LEDs 3, using tri- tunnel reception pipes 4 of R G B Receive at the same time and follow-up signal amplifies and processing.Being compared in existing color detection has three advantages：White light LEDs spectral width Extensively, all color spectrums of finding of naked eye are covered, therefore also can stability monitoring to muted colors such as yellow, grey；Using optical fiber The structure of probe 2 plus host 1, is connected by optical fiber 5, and probe 2 can be in the convenient installation of remote small space；Fibre-optical probe 2 use 10MM aspherical glass lens 2a, and white light is focused on, may exit off and more than object 60MM be monitored, while adjusts spy Head lens and fiber position, it is possible to achieve big-and-middle small light spot is freely adjusted, and can detect planar object, small-sized punctiform object etc.. The color of real-time detection object on automatic assembly line, is particularly suitable for the automatic chromaticity printing of printing house, different colours on assembly line The Automated Sorting System of object.The present invention is to use a kind of new color detection mode, sends white light by LED and is used as light Source, uses the reception pipe of tri- kinds of colors of RGB in receiving portion, docks received white light respectively and handled, obtain RGB tri- The signal value of path.Then 32 ARM chips of host are AD converted three road signals, and bright value signal is carried out numeral Change, then ARM chips carry out calculating processing to the light value of RGB three-ways according to special process, realize the automatic inspection of color Survey and distinguish, host computer or controller are then generated output to according to different algorithms so that machine carries out point of color automatically Pick and distinguish；ARM high speeds send white light, send 15000 white lights each second, then object color is detected, and realize The color detection of height, so can realize real-time auto color detection in High-Speed Automatic equipment；By special small Size fibers lens, may exit off object, position is detected farther out, so as to can also install optical fiber in the narrow and small place of station Lens.

Present embodiment has the following advantages that：

First, white light LEDs shine as detection light source, realize the detection of wide spectrum.

2nd, host is separated with fibre-optical probe, realizes remote detection and small space installation.

3rd, external fibre-optical probe can have other different shapes or installation dimension.

4th, probe can detect big planar object and small punctiform object with automatic focusing.

5th, host is processed by 32 movement pieces of ARM, sends the white light of 15KHZ, receiving portion is passed back by optical fiber Host, then analog circuit signal is amplified, the a/d converter carried by ARM carries out 12 AD conversion, by analog signal number Word, the size real-time display of data is on seven section of eight word display screen of LED.
