Abstract
The utility model discloses a workpiece identifying and positioning backlight tray for a five-axle blade grinding machine visual system, and relates to a background device beneficial to the identification and positioning of the two-dimensional graphic profile of a workpiece. The workpiece identifying and positioning backlight tray is provided with a hollow frame, an electrode, a frosted film, a transparent organic glass plate, a reflecting film and LED (Light-Emitting Diode) light sources, wherein the hollow frame is provided with latticed array holes; the electrode is arranged on the side end face of the hollow frame; the transparent organic glass plate is arranged below the hollow frame, and is connected with the hollow frame; the frosted film is arranged on the upper surface of the transparent organic glass plate; the reflecting film is arranged on the lower surface of the transparent organic glass plate; the LED light sources are arranged on the two side end faces of the transparent organic plate. By adopting the workpiece identifying and positioning backlight tray, the distinction degree between the workpiece and a background is increased, the workpiece profile in a formed image is clear, the identification accuracy of the visual system is increased greatly, and complete workpiece profile information can be acquired by using an industrial visual system. Standard parts are adopted in the background tray, so that the principles of lot sizing and interchangeability are met, and popularization is facilitated.
Description
Technical field
The utility model relates to a kind of Background apparatus that is conducive to workpiece X-Y scheme profile identification location, especially relates to a kind of for five axle blade grinding machine vision system workpiece identification and location charging tray backlight.
Background technology
At present, full-automatic processing is very general, and unmanned processing has even been realized in a lot of workshops.Full industrial vision is being brought into play the effect of mankind's eyes at automation manufacture field, for identification, location workpiece to be machined.Industrial vision system has harsh requirement for workpiece imaging effect, and image quality is subject to the impact of the factors such as imaging device, surround lighting, workpiece and background area calibration, and workpiece imaging must be accurate, clear.Only has desirable workpiece image quality, the smooth errorless operation of guarantee industrial vision system.The lighting source of industrial vision system has annular light source, coaxial-illuminating light source, oblique illumination light source, background light source etc.For need to gathering the industrial vision system of the accurate profile information of workpiece, in the time that workpiece is white metal material, can produce reflective phenomenon and be shone the fuzzy partial contour information dropout that causes of target edges thereby workpiece surface roughness is lower, cause metal works and metal charging tray background area calibration very low, be unfavorable for the rim detection of system.How to make workpiece image quality obtain satisfied effect, become the problem of very paying close attention in the industry.
Summary of the invention
The purpose of this utility model is in order to overcome the impact of contextual factor on workpiece image quality, provide and can improve workpiece and background area calibration, make workpiece profile clear picture, the one that improves the recognition accuracy of vision system is used for five axle blade grinding machine vision system workpiece identification and location charging tray backlight.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The utility model is provided with hollow out frame, electrode, frosted film, transparent plexiglass plate, reflective membrane and LED light source;
Hollow out has been set up latticed array hole, electrode is located at hollow out frame side end face, transparent plexiglass plate is located at hollow out frame below and is connected with hollow out frame, frosted film is located at transparent plexiglass plate upper surface, reflective membrane is located at transparent plexiglass plate lower surface, and LED light source is located at the both sides end face of transparent organic plates.
Described hollow out frame is preferably the hollow out frame of U font, and the hollow out frame of U font is stuck in the both sides end face of transparent plexiglass plate, and bonds with the both sides end face of transparent plexiglass plate.
Described electrode preferably adopts Telescopic spring electrode.
Described frosted film and transparent plexiglass plate preferably bond; Described reflective membrane and transparent plexiglass plate preferably bond.
Each hole in the latticed array hole of described hollow out frame is preferably the hole that dimensions is identical, and the shape in hole is preferably rectangle.
Compared with the prior art, the beneficial effects of the utility model are as follows:
When use, workpiece is placed in the corresponding hole of hollow out frame.Described reflective membrane can see through lucite by photoemissive LED lamp light and evenly reflex to frosted film, and the light that simultaneously sees through frosted film becomes soft stable.Be radiated at so the very stable and uniform of light on workpiece, thereby can improve the contrast of workpiece and background, the clear-cut of workpiece is presented, realize better identification and the location of industrial vision system to workpiece.
Charging tray backlight itself described in the utility model is not with electric supply installation, just be provided with pair of electrodes in hollow out frame one side, in the time that charging tray backlight moves to operating position, electrode contacts with the current electrode on external equipment, light LED light source, charging tray backlight enters duty.Electrode adopts Telescopic spring electrode, can slow down charging tray backlight and move to the impact of operating position, and the equipment work of making is more reliable and stable.Charging tray backlight described in the utility model can be according to batch different product, the latticed array hole (special size groove) of preparation different size.Because workpiece quantity is many, in order to facilitate the quick feed of workman storehouse material loading, workpiece can adopt random placement in charging tray backlight, and it is random so making workpiece placement location in charging tray backlight, neither fixed-direction neither fixed position.In order to make the terminal-collecting machine grabbing workpiece exactly of manipulator, can be by adopting vision location technology and manipulator co-ordination to complete determining of the location of workpiece and direction.As can be seen here, the utlity model has the discrimination that improves workpiece and background, order become the workpiece profile in image clear, can greatly improve the recognition accuracy of vision system, guarantee industrial vision system can gather complete workpiece profile information.Background charging tray can all adopt standard parts and components, meets the principle of mass and interchangeability, is conducive to apply.
