Smart phones are the 3C products with the largest market share, and the huge market share has created white-hot competition among cell phone manufacturers, and the design of cell phone shells, screens and other accessories tends to be diversified.Cell phone shell is an important part of the composition of the phone, quality testing requirements are also very strict.
Cell phone backshells are curved, and measurements include flatness, contour, etc. Traditional inspection techniques are difficult to meet the demand.
Adoption of POMEAS self-developed line laser sensor with 3DOS measurement system,to do 3D data acquisition and comparison of measurement analysis, scanning the back of the cell phone shell point cloud data and standard documents for comparison, according to the parameters of the color gradient to determine the deviation value of the contour, and directly control whether the product size is in line with the requirements.
1. Detection speed can be achieved within 10s, suitable for production line high-volume product inspection.
2. Measurement accuracy can reach ±3μm, high measurement precision.
3. non-contact detection, to avoid errors due to contact with the surface of the workpiece.
