Abstract
The utility model provides a device for the automated optical inspection of the surface of a product. The device comprises a rack and a stage arranged on the rack, wherein a light source and a camera lens for acquiring the image of the surface of the product are mounted at the upper part of the stage; the light source is particularly a three-color LED (light-emitting diode) comprising a red LED, a green LED and a blue LED which are connected with a light source controller via wires; and the camera lens is connected with an image analysis host computer via optical fiber. By using the three-color LED (red, green and blue) as the light source and adjusting the color and light intensity of the light emitted by the LED by the light source controller, the device of the utility model can discriminate the image of the surface of the product to be inspected or the button, transfer the image shot by the camera lens to the image analysis host computer, carry out the analysis and comparison on the color, shape and standard images of the graph or button to judge whether the product is qualified, and display the result of analysis and comparison. Compared with the existing single-color light, the device of the utility model has the advantages of more flexible use and higher practicability.
Description
Technical field
The utility model relates to a kind of checkout facility that utilizes illumination testing product surface condition.
Background technology
Be applied to automatic visual inspection (AOI, Automated Optical Inspection)) Ce Shi checkout facility as silk-screen detection, surface element device etc., when general use black and white camera detects product, because the surperficial surveyed area change color of product is obvious, what existing AOI checkout equipment used is monochromatic source, and the light-source brightness value is manually controlled, during detection, because light source is monochromatic light, some pattern and button can't detect, as the silk-screen detection etc.
The utility model content
The technical problems to be solved in the utility model provides the product surface automatic optical checking equipment of a kind of light color, adjustable brightness.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of product surface automatic optical checking equipment, comprise frame, the objective table of carrying product to be detected on frame, camera lens at light source that product irradiation light on objective table is installed above the objective table and collection product surface image, described light source is a led light source, LED by red LED, green LED and three kinds of colors of blue led forms, and the LED of three kinds of colors all connects with light source controller by circuit, and described camera lens connects with a graphical analysis main frame by optical fiber.
As the improvement to such scheme, led light source is installed in the lampshade, and LED is distributed in the lampshade inside circumference, and camera lens is positioned at the lampshade middle part.
Operation for convenience, objective table is movably installed on the frame by screw mandrel and guide rail, objective table by screw mandrel by step motor drive.
The utility model adopts the LED of three kinds of colors of red, green, blue as light source, regulate color and the brightness that LED emits beam by light source controller, the image or the button that enable product surface to be measured need be detected obviously distinguish, by transferring to the graphical analysis main frame after the lens shooting color, shape and the standard picture of figure or button are analyzed contrast again, it is qualified to judge whether, and show, compare with existing monochromatic light, practicality is more flexible, and practicality is stronger.
Description of drawings
Accompanying drawing 1 is the utility model embodiment one-piece construction synoptic diagram;
Accompanying drawing 2 is a present embodiment lampshade structure synoptic diagram.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:
Shown in accompanying drawing 1,2, this programme has proposed a kind of automatic optical checking equipment that is used to check product surface figure, button.This equipment comprises a frame 1 and is installed on objective table 2, light source 3, camera lens 4 and light source controller 5 on the frame 1.
Wherein, objective table 2 is positioned at frame 1 upper surface, and light source 3 and camera lens 4 are positioned at objective table 2 tops, is used for the product to be measured on the objective table 2 is taken.This programme and prior art greatest improvement part are for to be improved to light source 3 by redness by original monochromatic light, the light source green and blue led is formed, and intensity and brightness by light source controller 5 scalable shades of colour LED, be that whole light source presents needed color, so that the figure of the required detection of product surface or button color can be easy to differentiate under camera lens 4 irradiations more, image process light transmission to graphical analysis main frame through camera lens 4 collections, the standard picture that pre-deposits in the image that the graphical analysis main frame is gathered camera lens 4 and the main frame is analyzed, then the result that contrasts of output.
In order to guarantee the radiation response of light at product surface, led light source is installed in the lampshade 6, and LED is distributed in the lampshade inside circumference, and camera lens 4 is positioned at lampshade 6 middle parts.And the operation when detecting, objective table 2 is movably installed on the frame 1 by screw mandrel and guide rail, and it moves by step motor drive.
It more than is the preferable implementation of the utility model; in addition, the utility model can also have other concrete implementations, need to prove; in any conspicuous replacement that does not break away under the present utility model design prerequisite, all within the utility model protection domain.
