What are Vision inspection systems?

Vision inspection systems (sometimes referred to as machine vision systems) provide image-based inspection automated for your convenience for a variety of industrial and manufacturing applications.  Though not a new technology, 2D and 3D machine vision systems are now commonly used for automated inspection, robot guidance, quality control and sorting, and much more. Let’s take rubber stoppers as an example to explain the vision system applications.

Rubber closures are an essential packaging for parenteral drug products, and they can be a source of particulate matter. The machine vision systems can provide imaging-based automatic inspection and process the image data in applications of automatic inspection and process control. Cameras are used to capture the image data from the examined closure. We didn’t say 100% vision inspection can detect visible defects but 99.99% is available. The defects are some flaws, damages, scratch, missing-injected, burr, deformation and other colors.

Sipotek have developed its machine vision techniques for over 16 years since 2002. Our automatic optical vision inspecting system is designed to inspection a variety of products ranging from electronic, plastic, rubber, magnetic metal industry. In pharmaceutical filed, the vial plungers are inspected strictly with an modular vision system. During inspection process, the system continuously conveys the plungers through a glass plate, undergo through the endoscope cameras after which the products are either accepted or rejected.

The inspection process are not obscure to understand.

Prepare your rubber stoppers / rubber plungers in the container. The operator pours the parts into the vibration bowl feeder. If you want to have an automatic feeding, a hopper is a good idea. The parts are oriented from a hopper into the vibratory bowl feeder, out onto an accumulation track.

A glass plate, the rotating mechanism whee,l presents the products for the vision section. They will stand in order one by one, ready for image-capture and quality-check. Here the top and steep side and bottom are inspected for defects and the total height, diameter are measured.

A special mechanism with an ejector blows failed components off the glass plate and into the rejection bin. Parts that have been accepted continue to be transported another OK bin, thus separating bad ones from the good ones.

An intelligent product tracking system supports counting ability and the correct allocation of the parts into 2 separate station: accept and reject. This results in very low levels of false rejects and false accepts.


The automation visual inspection in quality control is not a brand new idea around the world but last long years. What we can do is focusing on improving the performance of the process, assisting in reducing costs of defects with a higher and safer condition. Sipotek will keep further supports industry leader in these pharmaceutical manufacturing fields by minimizing the risk of component related issues in drug fill-finish operations.
