Description
Technical Field
The utility model relates to a glass check out test set technical field specifically is a glass limit light inspection device.
Background
The limit light inspection machine is a common glass surface inspection device, and traditional limit light inspection machine is put into the lighting lamp house with the glass edge in, utilizes the highlight to shine the glass edge, because the glass body is transparent, shines the glass edge and can lead to glass body luminance to improve, and the naked eye discernment glass surface defect of being convenient for improves naked eye discernment defect probability.
However, the existing edge light inspection machine has the following defects:
firstly, because the light source mode is the scattering mode, does not lead, and a large amount of light shines and does not shine glass surface at the lamp house surface, and the light source is effectively utilized.
Secondly, because the light source mode is the scattering mode, the light source transmission does not have the directionality, leads to the light inhomogeneous on the glass of shining, and the visual inspection effect is not ideal.
Thirdly, because the light source mode is a scattering mode, the light source mode has no directivity, and high-power illumination is needed for improving the overall brightness
Fourthly, due to the adoption of high-power illumination, the energy consumption is increased. Increasing cost and wasting energy efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a glass limit light inspection device, this inspection device can improve the utilization efficiency who detects the light source, improves the accuracy of glass surface defect inspection.
The utility model provides a technical scheme that its technical problem adopted is:
a glass edge light inspection device comprises a glass conveying roller way and a lamp box, wherein an upper lamp shade and a lower lamp shade which are identical in structure are vertically arranged in the lamp box, the upper lamp shade is rectangular and columnar, the inner wall of the upper lamp shade is a frosted surface, a baffle is arranged at the top of the upper lamp shade, the top surface of the baffle is a light shading surface, the bottom surface of the baffle is a light reflecting surface, a semi-circular arc-shaped transparent incident plate is arranged below the baffle, and a light source is arranged between the baffle and the transparent incident plate; the bottom of the upper lamp shade is provided with a bevel cut with an angle of 45 degrees, and the bevel cut is provided with a transparent light emitting plate; the upper lampshade and the lower lampshade are symmetrically arranged along the glass conveying plane, so that light transmitted out of the upper lampshade and the lower lampshade irradiates the glass plane at an angle of 45 degrees.
Furthermore, the light sources in the upper lampshade and the lower lampshade respectively adopt two different light colors.
Furthermore, a vertical glass limiting plate is arranged between the two light emitting plates of the upper lampshade and the lower lampshade.
The utility model has the advantages that:
the light source is guided to the surface light source through the lampshade by the traditional point light source or line light source, the light irradiating to the glass through the light emitting plate is more uniform, an even light band is formed in the glass body, the glass defect can be identified by naked eyes, and the identification efficiency of the edge light inspection to the defect is improved.
And secondly, the lamp shade is used for guiding the light emitted by the light source to the glass as much as possible, so that the illumination to the inner wall of the lamp box is reduced, the utilization efficiency of the light is improved, and the energy consumption can be reduced under the same illumination.
And light sources in the upper lampshade and the lower lampshade are not interfered with each other, so that the glass can be irradiated by two light colors for inspection.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an enlarged schematic view of the upper lampshade of the utility model.
Detailed Description
With reference to fig. 1 and 2, the utility model provides a glass edge light inspection device, which comprises a glass conveying roller way 1 and a lamp box 2, an upper lamp shade 3 and a lower lamp shade 4 with the same structure are vertically arranged in the lamp box 2, the upper lamp shade 3 is rectangular column-shaped, the inner wall of the upper lamp shade 3 is frosted, the top of the upper lamp shade 3 is provided with a baffle 5, the top surface of the baffle 5 is a light shading surface, the bottom surface is a light reflecting surface, a semi-arc transparent incident plate 6 is arranged below the baffle 5, and an upper light source 7 is arranged between the baffle 5 and the transparent incident plate 6; the bottom of the upper lampshade 3 is provided with a 45-degree oblique cut which is provided with a transparent light emitting plate 8; the upper lamp shade 3 and the lower lamp shade 4 are symmetrically arranged along a glass conveying plane, so that light transmitted by the upper lamp shade 3 irradiates the upper plane of the glass 9 at an angle of 45 degrees, and light transmitted by the lower lamp shade 4 irradiates the lower plane of the glass 9 at an angle of 45 degrees.
