Three dimensional inspection of electric bicycle frame

Bicycle is the most environment-friendly means of transportation, and electric bicycle is becoming more and more popular among citizens. Electric bicycle has the advantages of convenience, economy and environmental protection that many other means of transportation do not have. With the continuous boost of the new national standard, sharing economy and real-time distribution industry, the electric bicycle industry has ushered in explosive growth, but the attendant potential safety problems have also been paid attention to.

Pracical problems
1. The customer is the manufacturer of motorcycles and electric bicycles. The electric vehicle frame designed with the concept of portability and environmental protection has a black surface and large radian.

2. The fixed scanner needs to be sprayed with developer, which is inefficient. Customers require 3D scanner to scan high-precision and complete data with high efficiency, detect the error of actual processing and ensure driving safety.

Solutions

Equipment: Handheld 3D scanner HOLON 771

All blue laser scanning is adopted, fearless of black surface objects; The scanning speed is 1350000 measurements / s, and the scanning can be completed in 10 minutes; The precision is as high as 0.02mm, with dual industrial cameras, automatic splicing technology of marker points and independently developed scanning software, which has high scanning precision and work efficiency. Through the comparison with the original 

data, the actual machining error is detected.
