Products: HSCAN331 3D Scanner & MSCAN Global Photogrammetry System
Scanning object: Body frame, auto parts
Scanning requirements: Get accurate 3D data of the assembled body frame to obtain the deviation value
Aim: 3d scanning of the body and automobile parts to obtain the product deviation value for easy correction
Automobile quality control is interspersed throughout the process from R&D to production to after-sales. Good quality management in the process of production and R&D can help automobile enterprises improve the quality level of final products. The emergence of laser 3d scanners has greatly improved the efficiency of the car in product development, product design, quality management and other aspects.
In the trial production stage of automobile R&D and production, the trial production personnel of the automobile manufacturer will carry out the trial assembly of the whole vehicle, thereby discovering problems in the assembly (such as mutual interference of components, unreasonable arrangement, etc.), and informing the design department to make corrections. In the past, the car manufacturer used the traditional three-coordinate contact measurement method, but because the measurement with the hard probe is easy to deform the product, and the measurement time is very long, the requirements for the inspectors are also very strict, so there are many Pain points, car manufacturers urgently need a simple and efficient three-dimensional detection method.
Next, Scantech will show you how 3D scanners solve the pain points of the automotive industry.
The customer is developing a new product, it is found that some parts of the body cannot be assembled accurately, so it is necessary to detect the position of product deviation and to facilitate correction. Some parts of the car are plastic products, hard measurements such as three-coordinate cause deformation on the product and cannot be detected accurately, so they want to seek a solution towards to Scantech.
After understanding the products of automobile manufacturers, Scantech found two problems:
The size of the detected auto parts is different, and the structures are mostly curved surface and complicated.
The detected car body model is large, and the customer has high requirements for precision.
Considering the above two factors, Scantech decided to adopt HSCAN331 hand-held 3d scanner combined with MSCAN global photogrammetry system to reduce the volume error and greatly improve the detection accuracy.
Step1: Mark reflective marking points and coding points, place the ruler. The position of the ruler should be connected with the whole code point.
Step2: The MSCAN global photogrammetry system captures the corresponding marker points and code points at various angles, and calculates the overall marker points to obtain marker point data.
Step3: Importing the Marking point into scanning software, scanning it by handheld 3D scanner.
Step4: Digital model and scanning data are fitted and aligned for 3D detection and analysis.
Step5: Adjust and optimize the shape of the product based on the inspection data.
Caution: The corner of a locomotive and its flank, the marking point and coding point of both sides need to be photographed into the global photography system at the same time.
3D Scanning working time
It takes 30 minutes to mark points.
It takes 30 minutes to scan.
It takes 5 minutes to generate inspection report.
65minutes in total.
3D scanning plays an indispensable role in the field of automobile quality control nowadays. Due to the high-efficiency and portable characteristics, HSCAN 3D scanner has played a strong advantage in scanning various medium and large objects with multiple curved surfaces and complicated structures. As an industrial-grade 3D scanner, HSCAN 3D scanner can easily control various auto parts and automobile shapes, which brings great convenience to the quality control of automobile assembly.
