A collinear adjustment device for a line array camera

Abstract

A collinear adjustment device for a line scan camera related to the field of glass defect inspection devices, the device comprises a base plate, a positioning plate, a support plate and a connecting seat; There are two screw holes on the board surface corresponding to the horizontal and vertical directions of the sphere, one screw hole is installed with a screw head corresponding to the limit screw screwed into the bottom plate, and the other screw hole is installed with a screw head A horizontal support plate is fixed on the side of the positioning plate facing away from the bottom plate, and the upper part of the support plate is connected with a connecting seat; the device can meet the requirements of collinear alignment of multiple line scan cameras. The error is controlled within the required range of no more than 0.2 mm, thus effectively guaranteeing the data accuracy of glass defect inspection.

Description

【Technical Field】 [0001] The invention relates to the field of glass defect inspection devices, in particular to a collinear adjustment device for adjusting multiple line scan cameras for defect inspection in a glass production line. 【Background technique】 [0002] It is known that the existing glass production line usually uses 10 line scan cameras to be installed on a long beam with a span of 6 meters when inspecting products for defects, and then uses these 10 line scan cameras to scan the glass line by line. To achieve the goal of uniform defect detection on glass; at present, the 10 linear array cameras need to be firmly installed on the side of the long beam during the inspection process, and the collinear error must not be greater than 0.2 mm. If the collinear error is too large , It will cause the defect detection deformation and incompleteness, which will cause the detection to lose its effect. However, in real applications, the side of the long beam will inevitably prod...

[0002] It is known that when the existing glass production line inspects products for defects, it usually installs 10 line-scan cameras on a long beam with a span of 6 meters, and then uses These 10 line-scan cameras scan the glass line by line continuously, so as to achieve the purpose of uniform defect detection on the glass; at present, these 10 line-scan cameras need to be firmly installed on the side of the long beam during the inspection process, and require The collinear error cannot be greater than 0.2mm. If the collinear error is too large, it will cause deformation and incompleteness of defect detection, which will cause the detection to lose its effect. Some irregular deformation occurs. According to the preliminary measurement, the flatness error exceeds 5 mm. Therefore, after the line array camera is positioned and installed on the side of the long beam according to the conventional method, the collinear error is often greater than the design requirement; usually, the application They all use the installation of spacers under the camera positioning plate to achieve the purpose of adjusting the collinearity error, but due to the length of the long beam, it is difficult to ensure the collinearity of 10 line array cameras in practical applications due to the length of the long beam. The error can always remain stable, that is, the existing glass defect inspection often affects the accuracy of the inspection results due to the collinear error of the line scan camera
