Embodiment Construction

[0017] Such as Figure 1~3 As shown, a size detection device for an automobile windshield includes a measuring platform 100 for placing the measured windshield 400, and a three-dimensional scanner 200 for scanning the measured windshield 400 is arranged on the side of the measuring platform 100. A controller 300 electrically connected to the 3D scanner 200 is disposed beside the 3D scanner 200 . During measurement, the point cloud coordinates of the three-coordinates of the glass 400 surface can be obtained by the three-dimensional scanner 200, and the points are fitted into a curved surface by the data processor 310 of the controller 300, and the points between the fitted curved surface and the target curved surface are compared. The difference, the mean square error of the difference between each line, and the mean square error between the detection points on the surface, the user can judge whether the windshield 400 is qualified according to the above three indicators.

Abstract

The invention relates to a size detection device for windshield glass of an automobile, which comprises a measuring table for placing the size of the windshield glass to be measured, and a three-dimensional scanner for scanning the size of the windshield glass to be measured is arranged beside the measuring table. A controller electrically connected to the three-dimensional scanner is arranged on the side; the invention also relates to a working method of a size detection device for an automobile windshield. The invention has reasonable structure and convenient operation, can detect the shape of the windshield glass, does not need specific inspection tools, and has high measurement accuracy.

Description

technical field [0001] The invention relates to a size detection device of an automobile windshield and a working method thereof. Background technique [0002] At present, to detect the size and profile of the formed automobile windshield, it is usually attached to the electronic inspection tool that is the same as the required glass surface, and the electronic probe is arranged at several important points on the electronic inspection tool. The deviation between the detection points is used to determine whether the windshield is qualified, but there are the following problems: [0003] 1. Each type of glass requires a special inspection tool, and the cost of the inspection tool is relatively high; [0004] 2. The inspection tools required for the production of various products are different, and it is cumbersome to disassemble and replace back and forth; [0005] 3. The detection accuracy is low. Contents of the invention [0006] In view of this, the object of the pres...
