In-house Technology/R&D

World’s First 3D Inspection Technology

This world’s first 3D inspection technology has been developed in a NEDO-subsidized project.

Our Tablet Visual Inspection System was adopted as their subsidized project for practical application and development of industrial technologies of the New Energy and Industrial Technology Development Organization (NEDO) and becomes the world’s first system of this type equipped with the 3D camera. Only Viswill, the company with an established reputation in tablet visual inspection, can materialize the technology.

Reliable inspection of tablet shapes
The optical-cross method traces the surface of a tablet and thus can accurately detect the shape of the tablet, thus attaining the highest precision. It also precisely detects capping defect and shallow and deep division lines.
Tablets coated in the same color can be accurately distinguished.
The system can inspect a slight chip, insufficient coating, coating in the same color as the tablet body, and spotted tablets with high accuracy.

Leading-edge Color Camera Technology

High-precision and stable inspection without compromising the processing speed

Highly-sophisticated 3CCD camera combined with our unique ‘Color-space filtering process’ has been contributed to this high-precision and stable inspection at high speed.

Technology with high color reproducibility
Colors can be reproduced with high reliability, and images have the same optical axis, resulting in vivid images.
A setup gentle to a user
Color defects can easily detected with our simple user-friendly setting.
