Description
Technical Field
The utility model particularly relates to a light filling structure for machine vision measuring apparatu.
Background
The technology is used for light supplement of the machine vision measuring instrument. The machine vision measuring instrument manufactured by the company is used for the fields of measuring liquid level, belt deviation and the like. The explosion-proof shell is used, the camera module is adopted to realize on-line detection, and the machine vision technology is utilized to realize unmanned monitoring of the industrial field. Because the machine vision has a high requirement on the field light condition, under the condition that the light is dark, the CMOS sensor module cannot receive the picture which can be used for analysis, and light needs to be supplemented to the field.
The existing machine vision measuring instrument has higher requirements on light rays of a working site, and needs to supplement light to the site, and one of the existing light supplementing schemes is to supplement light by using an external light source, namely, the light is supplemented by using one light source outside the measuring instrument. The explosion-proof requirement of the industrial field also needs to be considered for the external light source, the common light source cannot meet the requirement, and the linkage technology of the light source and the visual measuring instrument is complex.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a light filling structure for machine vision measuring apparatu to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a light filling structure for machine vision measuring apparatu, including the installation sheet metal component, the installation sheet metal component sets up in explosion-proof shell, be equipped with the camera module through the bolt on the installation sheet metal component, it is cotton to have annular lamp plate and buffering bubble in proper order on the camera module, evenly be equipped with four mounting holes on the annular lamp plate, there are four lamp plate installed parts in camera module both sides through screw fixed mounting, four lamp plate installed parts in both sides pass the mounting hole and offset with the buffering bubble is cotton, the cover has the diffuser plate on the buffering bubble is cotton, diffuser plate one end flushes with the buffering bubble mutually, diffuser plate and buffering bubble are cotton and offset with explosion-proof glass window, explosion-proof glass window bonds one end in explosion-proof shell, explosion-proof shell is the cavity round.
Preferably, a plurality of LED lamp posts are uniformly and fixedly mounted on the annular lamp panel, and the annular lamp panel is made of an aluminum back plate.
Preferably, the surface of the diffusion plate is coated with a frosted layer.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model has compact structure, reasonable design, better adaptability to the condition of dark ambient light and better adaptability to the condition of dark ambient light; the buffering bubble through setting up is cotton plays the effect of isolated lamp pearl and camera module, guarantees that the light of light filling lamp plate does not directly shine in the camera module.
