Embodiment
In order to make those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present inventionAttached drawing, is clearly and completely described the technical solution in the embodiment of the present invention, it is clear that described embodiment is onlyThe embodiment of a part of the invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill peopleMember's all other embodiments obtained without making creative work, should all belong to the model that the present invention protectsEnclose.
It is to be appreciated that " on ", " under ", "left", "right", " front " mentioned in the implementation below of the present invention" reverse side " etc. on the basis of the direction shown in each figure, these words for being used for limiting direction are intended merely to facilitate explanation,The limitation to concrete technical scheme of the present invention is not represented.
It is shown referring to Figures 1 and 2, the embodiment of the invention discloses a kind of vision system environmental control system, for preventing workIndustry camera 1 and provided for industrial camera 1 illumination headlamp 2 it is contaminated, including supply part 3 and be connected to 3 lower section of supply partInstalled part 4, wherein industrial camera 1 and headlamp 2 be arranged on supply part 3 top；
Supply and the downward flow-guiding channel 5 entered for inert gas is provided with the side of part 3, be located at work in supply part 3Downward visual channel 6 and illumination passage 7 are further respectively had at 2 underface of industry camera 1 and headlamp, after flow-guiding channel 5 is bentConnected respectively with visual channel 6 and illumination passage 7；
Visual channel 6 and illumination passage 7 are extended in installed part 4 out of supply part 3, and penetrate through the lower surface of installed part 4.
The vision system for monitoring forming process is provided with the present embodiment, in molding room, vision system includes industryCamera and headlamp, wherein industrial camera are used to gather visual pattern, and headlamp is used to provide illumination for industrial camera.
Supply part and installed part are set on industrial camera and headlamp, the flow-guiding channel of inert gas from supply part is drawnEnter, and enter installed part lower part through visual channel and illumination passage.Whole environmental control system is installed on molding room by installed partOn interior corresponding installing component, so that inert gas is finally filled with forming cavity from installed part lower part through being molded indoor installing componentIt is indoor.
Total is sealing structure, and the critical component of industrial camera and headlamp is arranged in the sealing structure, is madeIndustrial camera is observed inside molding room by visual channel, and headlamp is provided needed for observation by illumination passage for industrial cameraThe structure of illumination, visual channel and illumination passage can reduce the probability being deposited by metal volatile matter, while industrial camera and photographBright lamp is isolated with vacuum environment, it can also be ensured that the two equipment are used in home.
