A well-known mold manufacturer in Xiangtan needs to conduct three-dimensional inspection of automobile foam film. Hualang 3D engineers use the three-dimensional photogrammetric system HL-3DP to detect automobile foam film, and compare and analyze the obtained three-dimensional data with the original three-dimensional data. The overall deviation of the actual workpiece and the CAD drawing, check whether the quality is qualified.
Practical problems
1. The automobile foaming film mold has a huge body, different surface contours, complex structure, and many curved surfaces, making it difficult to measure.
2. Using traditional measurement methods, only part of the data can be obtained, and curved surfaces and parts with large slopes cannot be measured, resulting in an incomplete amount of data obtained, and it is impossible to detect the quality of automobile foam film molds.
Holon solutions
Customers need to carry out quality inspections on automobile foamed films. Traditional measurement methods have very low efficiency and large errors. In response to the problems faced by customers, Hualang 3D engineers proposed a solution to use the scanning device HL-3DP to take a global picture of the automobile foaming film mold, obtain the three-dimensional coordinates of the mark points of the inspection part, and import the taken pictures into the software for calculation. The calculated data and the original digital and analog diagrams are tested and compared to obtain the error value between the auto foaming film molds.
Using the three-dimensional photogrammetry system HL-3DP to take pictures of the automobile foam film, it only takes 30 minutes to obtain the three-dimensional data of the automobile foam film mold, and the measurement accuracy is very high. Quickly detect the difference between the automobile foam film (CAD) model and the product, check whether the automobile foam film mold is qualified, and effectively solve the problems faced by customers.
