Automatic Tablet Inspection

Automatic Tablet Inspection


Automatic Tablet Inspection won the competition of Food & Pharmaceutical Machinery Productivity 4.0 Product in 2016.
Inspection efficiency up to 120,000 tablets/hour.

Optical inspection principle:

Automatic optical inspection is a common method in industrial processes. In the use of optical instruments to obtain the surface state of the finished product, and then inspect foreign objects, abnormal patterns and other defects by the computer image processing technology. Tablet inspection machine is used the optical illumination and image measurement technology to inspect size mismatch, surface foreign object, pucker, stained, breakage, twining of the tablet.


1. Follow the requirements of cGMP、PIC/S、21CFR Part 11
2. Using high-sensitivity CMOS CCD to take high-resolution images. Inspect hair and foreign objects, adhesion of dirt and foreign matters, improve the detection accuracy of the edge of the tablet.
3. High-speed image processing technology to improve the quality of inspection process and save manpower.
