Background technology
At present, after product completes production process, many by artificial directly visual detection to the detection of product, and use kind of calliper.The mode of this Manual Visual Inspection wastes time and energy, and manual intervention is too many, there are the factors of instability.
In recent years, machine vision, as the cutting edge technology of automation industry, by feat of vision system noncontact, the outstanding advantage such as speed is fast, precision is high, on-the-spot antijamming capability is strong, is widely used, achieves huge economic benefit in manufacturing industry.In production in enormous quantities, NI Vision Builder for Automated Inspection can fast, the quality of testing product accurately and efficiently, compared with employing human eye detection, production efficiency is greatly improved.NI Vision Builder for Automated Inspection detects and adopts detector lens (as CCD) to carry out IMAQ to product corresponding site, and by the image transmitting collected to detecting computer, carrying out respective handling, thus realize the Quality Detection to product by detection computer to the image collected.Detector lens needs light source polishing when carrying out IMAQ usually, to illuminate test product, and in prior art, the light source adopted in NI Vision Builder for Automated Inspection is generally single lamp body, its range of exposures is comparatively large, and brightness disproportionation, for the reflective or more shallow product of color, be difficult to the details telling the tested position of product, also just affect Machine Vision Detection work.
In this context, present applicant has proposed a kind of light-source structure of vision inspection apparatus, namely propose this case application.
Summary of the invention
The purpose of this utility model is the light-source structure providing a kind of vision inspection apparatus, and it can obtain uniform illumination, can the details at the tested position of highlight products, hoisting machine vision-based detection operating efficiency and accuracy, and structure is simple, long service life.
For achieving the above object, the utility model adopts following technical scheme:
A kind of light-source structure of vision inspection apparatus, this light-source structure has a box-shaped enclosure, the lower end of box-shaped enclosure is designed to bright dipping end, bright dipping end is provided with Scrub diffusing panel, lamp socket is provided with in box-shaped enclosure, be formed with optical channel in the middle part of lamp socket, be equipped with lamp bar in the upper and lower side of lamp socket, lamp bar is located in PCB by LED array group and is formed; Be assembled with the annular light source of subsidiary polarizer inside the upper top of box-shaped enclosure, the residue surrounding medial surface of box-shaped enclosure is selected to be provided with white scattering film and brightness enhancement film.
Described box-shaped enclosure and lamp socket are aluminium matter matrix, and lamp socket contacts with box-shaped enclosure and connects and composes heat radiation system.
The lamp bar of described lamp socket upper and lower side is by being symmetrical arranged up and down; Lamp bar on same side has four, and the optical channel in the middle part of lamp socket is by four azimuthal spacings distributions.
Described lamp socket is box-shaped, and lamp socket upper and lower side is equipped with wire casing, and wire casing extends through the back side of the PCB of lamp bar.
The light-source structure of the vision inspection apparatus that the utility model provides, is combined by structure optimization, realizes light and evenly penetrates, for vision-based detection, can the details at the tested position of highlight products, hoisting machine vision-based detection operating efficiency and accuracy, structure is simple, long service life.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model preferred embodiment structural representation.
detailed description of the invention:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consult shown in Fig. 1, it is preferred embodiment schematic diagram of the present utility model, the utility model is about a kind of light-source structure of vision inspection apparatus, this light-source structure has a box-shaped enclosure 1, the lower end of box-shaped enclosure 1 is designed to bright dipping end 11, bright dipping end 11 is provided with Scrub diffusing panel 111, Scrub diffusing panel 111 can make light out evenly.Lamp socket 2 is provided with in box-shaped enclosure 1, optical channel 21 is formed in the middle part of lamp socket 2, lamp bar 3 is equipped with in the upper and lower side of lamp socket 2, lamp bar 3 is located in PCB by LED array group and is formed, the annular light source 4 of subsidiary polarizer is assembled with inside the upper top of box-shaped enclosure 1, the residue surrounding medial surface of box-shaped enclosure 1 is selected to be provided with white scattering film 5 and brightness enhancement film 6, realizes scattering and blast, fully merges the light in box-shaped enclosure 1.The annular light source 4 of the present embodiment is the double-colored light source of low angle height light, is configured with polarizer, has better development effect to the high narrow limit of light metal.Lamp bar 3 is located in PCB by LED array group and is formed, and brightness is good, is equipped with lamp bar 3 in the upper and lower side of lamp socket 2, makes the light in box-shaped enclosure 1 balanced.The light that lamp bar 3 on the upside of lamp socket 2 sends is through reflection, scattering, and the light that annular light source 4 sends is transported to bright dipping end 11 by the optical channel 21 in the middle part of lamp socket 2, penetrates through Scrub diffusing panel 111.In the present embodiment, the lamp bar 3 of described lamp socket 2 upper and lower side is by being symmetrical arranged up and down; Lamp bar 3 on same side has four, and the optical channel 21 in the middle part of lamp socket 2, by four azimuthal spacings distributions, during work, can select all or part of luminescence of lamp bar 3 according to actual conditions, to obtain desirable lighting effect, and also economize energy.
