Embodiment Construction
[0028] Such as Figure 1-6 As shown, in a specific embodiment of the glass optical distortion detection system of the present invention, the system includes a glass optical distortion detection board 10 and a workpiece 30 supporting frame 20 for manufacturing the workpiece 30 . The workpiece 30 is glass to be inspected.
[0029] Such as figure 2 , 3 As shown, the glass optical distortion detection signboard 10 includes a base plate. The front of the bottom plate is a flat surface, on which evenly distributed grids 11 are printed. In this embodiment, the grid 11 includes a plurality of uniformly arranged black squares, with white spaces between the black squares. These black squares are arranged in a square matrix. As shown in the figure, the size of the entire glass optical distortion detection board 10 is: 2438mm×1219mm, and the size of the black squares is 31.6mm×31.6mm; and the white space between the black squares is 6.4mm. Therefore, according to the perception of ...

The invention relates to a glass optical distortion detecting system and an optical distortion detecting method. The system comprises a glass optical distortion detecting board and a workpiece supporting frame. The board comprises a bottom plate with a smooth surface on which evenly distributed griddings are arranged. In an optical distortion detection, the glass optical distortion detecting boardand the workpiece supporting frame are arranged at interval, then a workpiece is placed on the workpiece supporting frame, and the transparent surface of the workpiece is aligned to the glass opticaldistortion detecting board; and the existence of optical distortion is judged for the workpiece by observing the griddings of the glass optical distortion detecting board by permeating the workpiece.The system can be directly installed on site in a production workshop of glass to be detected, thereby effectively reducing the time consumption for running to a darkroom, effectively avoiding carrying the glass to be detected, improving the work efficiency and the security, avoiding using costly projective equipment and greatly reducing the investment of instruments. The detecting device and system can be used in large scale so as to improve the work efficiency.
Description
technical field [0001] The present invention relates to optical distortion detection of glass, more specifically, to a glass optical distortion detection board and system, and a detection method using the system. Background technique [0002] Because glass has good light transmission, it is widely used in some occasions that need light transmission and observation, such as the front windshield of a car. The following takes the front windshield of a car as an example. It has high requirements on the optical distortion of the glass, and the use of glass that will cause optical distortion should be avoided as much as possible. [0003] After the front windshield is produced, optical distortion detection of the glass is required to observe and determine whether it can be used as automotive glass. Existing detection of glass is by setting a projector, and setting a glass sheet prepared with a grid at the outlet of the projector, and projecting the grid on the glass sheet onto a ...
