Product background

The continuation of the new crown epidemic has made people more aware of the importance of the pharmaceutical and medical device industries. In the pharmaceutical and medical device industries, machine vision inspection technology is often used for quality control in high-volume manufacturing environments. For example, in the production of medical products such as syringes and vials, machine vision is often used for quality monitoring. The global Covid-19 vaccination program, which will eventually cover some 7.8 billion people, will require a large number of vaccines, which cannot be produced without visual inspection.

In the broader pharmaceutical and medical device industries, machine vision can start with inspecting raw materials, all the way to inspecting finished products and their packaging. Product inspection can include size, shape, color, integrity, and the presence of defects or foreign objects. Packaging inspections range from detecting the fill level of vials and bottles, to ensuring the filling of blister packs. The presence and location of tamper-evident seals can also be detected, as well as other details regarding package integrity. It is also important to confirm the presence of labels, as well as to read and verify 1D/2D codes and human readable text. Using a serialized QR code on each package can be traced back to production from the point of sale. Machine vision lighting is a key part of ensuring accurate and repeatable measurements while performing all of these tasks.

Inspection principle:

The materials are arranged by vibrating plate, Linear vibration and non-destructive conveying, and the capacitance is stably and orderly transferred to the specific inspection station, and then the high-pixel sample image captured by the industrial camera is transferred to the image processing software. After the system analyzes and processes, it judges good and defective products, and controls the corresponding pneumatic components to eliminate the defective products, and finally collects qualified products.

Inspection details:

Machine vision lighting needs to provide the illumination intensity and uniformity required by the application in order to generate images with good contrast and signal-to-noise ratios to highlight features of interest. These characteristics are determined by the application itself. Factors such as the color, surface texture, shape, and reflectivity of the object being imaged all affect its interaction with light, which also determines which light source form and wavelength are best suited for a particular inspection task. The geometric position between the object, the light source, and the camera determines the orientation, the angle of illumination, and the angle at which the camera collects the light.

• High-speed, high-volume production requires precise pulses to "freeze" motion in the image.
• High illumination intensity is required to clearly capture small target information on moving objects, such as 1D and 2D codes.
• Lighting used in a clean room environment should generate less heat to prevent product aging.
• To maintain a stable level of illumination intensity and uniformity to ensure good manufacturing practice
