Description
Technical Field
The utility model belongs to the technical field of detection device and specifically relates to machine is examined to lamp.
Background
The light inspection machine is used for polishing the bottled products to be inspected by using a light source and identifying the bottled products by using a visual identification system so as to judge whether the bottled products contain foreign matters or not.
The light source for the visual identification system of the existing lamp inspection machine mostly uses the lamp strip or the lamp bead to directly irradiate the bottled product to be inspected, so that the illumination brightness of the bottled product to be inspected is not uniform enough, the visual identification system is not sensitive enough to identify foreign matters, and the yield of the bottled product is indirectly reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a tunnel type light source that illumination is more even is provided.
The utility model provides a technical scheme that its technical problem adopted is: the tunnel type light source comprises a light emitting part, a housing and a diffuse reflection part, wherein a light outlet is formed in the housing, the light emitting part is fixed in the light outlet of the housing and faces a cavity of the housing, a camera hole communicated with the cavity of the housing is formed in the wall surface of the housing, and the diffuse reflection part is fixed on the inner wall of the cavity.
Further, the number of the light emitting parts is two, and the two light emitting parts are fixed to the housing symmetrically with respect to the axis of the camera hole.
Further, a package box is included in which the light emitting portion is housed, the package box being fixed in the cavity of the housing symmetrically with respect to the axis of the camera hole.
Furthermore, the wall surface of the housing, which is provided with the camera hole and is positioned in the cavity, is an arc-shaped wall surface.
Further, the diffuse reflection part is diffuse reflection paper or a diffuse reflection coating layer.
Furthermore, the two ends of the housing along the length direction of the housing are provided with mounting holes which are uniformly distributed.
The utility model has the advantages that: compare with the light source for the machine vision recognition system is examined to lamp that the product directly shines of waiting to examine with current use lamp strip or lamp pearl, the utility model discloses a luminescent part, still include housing and diffuse reflection portion, be equipped with a light-emitting window on the housing, the luminescent part is fixed in the light-emitting window department of housing and towards the cavity of housing, be equipped with the camera hole with the cavity intercommunication of housing on the wall of housing, diffuse reflection portion fixes on the inner wall of cavity, the light that the luminescent part produced shines the reflection part on the cavity inner wall earlier, reflection part on the cavity inner wall can make light carry out multiple reflection in the cavity, it is more even to distribute when light jets out the cavity, thereby make the illumination luminance of production more even, shine illumination luminance on waiting to examine the product more even, make the vision recognition system discernment foreign matter more sensitive, the yields of product has been improved.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 3, a tunnel light source, including the luminescent part 3, the luminescent part 3 is a lamp strip, the lamp bead can produce bright devices, still include housing 1, be equipped with a light outlet on housing 1, for example housing 1 is box-like, hemisphere shell, have an open-ended hollow body, be equipped with at least one camera hole 101 with the cavity intercommunication on the wall of housing 1, still include diffuse reflection portion, diffuse reflection portion is diffuse reflection paper, diffuse reflection coating etc. can make light take place diffuse reflection's spare part or coating, diffuse reflection portion is paved and is fixed on the inner wall of cavity, luminescent part 3 fixes in the light outlet department of housing 1 and towards the cavity of housing 1, the light that luminescent part 3 produced shines earlier to the inner wall of cavity, the light outlet is shone out after diffuse reflection of diffuse reflection portion.
In order to provide sufficient illumination, two light emitting portions 3 are provided, and the two light emitting portions 3 are fixed to the housing 1 symmetrically with respect to the axis of the camera hole 101.
In order to prevent water drops from entering the light emitting portion 3, the light emitting portion 2 further includes a sealing case 2, the sealing case 2 is a case having a transparent plate on one side, the light emitting portion 3 is accommodated in the sealing case 2, the generated light is emitted through the transparent plate, and the sealing case 2 is fixed in the cavity of the housing 1 symmetrically with respect to the axis of the camera hole 101.
In order to make the illumination brightness uniform, the wall surface of the housing 1 in which the camera hole 101 is formed and which is located in the chamber is an arc-shaped wall surface.
In order to make the illumination brightness more uniform, the diffuse reflection part is diffuse reflection paper or a diffuse reflection coating layer.
In order to facilitate the fixed connection of the housing 1 and other structures of the lamp inspection machine through screws, the two ends of the housing 1 along the length direction of the housing are provided with uniformly distributed mounting holes 102.
