Example of detecting objects in a box

As we all know, the production and management of food and medicine are related to human life and health. If the quality of food/drugs threatens human life, it will be a great disaster. Therefore, all pharmaceutical manufacturers, especially world-renowned large manufacturers, attach great importance to the entire production process of drugs and even the packaging of the back-end.

American Banner Engineering International Co., Ltd. has good cooperation with many world-renowned pharmaceutical companies and food packaging manufacturers worldwide. Whether it is blister packaging of drugs, filling of liquid food, or capping, labeling, coding, and final box inspection, Banner can provide many solutions. The following introduces the application example of the company's iVu image sensor in object detection in packaging boxes.

In the pharmaceutical industry, drugs must eventually be boxed, and each box must be accompanied by the instructions for the drug.

Usually, the iVu image sensor is installed above the packaging line to ensure that each box is accompanied by an instruction manual. By setting the Match tool for detection, the Match tool can search for the object to be tested in a 360-degree range, so the instructions in the medicine box can be placed at any angle, but the surface must face up. When it is detected that there is no instruction manual in the medicine box, the sensor will send a FAIL signal to the production line, thereby removing the medicine box.

Similarly, for food packaging inspection, Banner's iVu image sensor can also be flexibly applied to the packaging box production line. It can be used to detect the status of objects during the packaging process. An internationally renowned milk powder manufacturer uses Banner's iVu product to detect whether there is a small spoon and whether the milk powder box is sealed. During the inspection process, the iVu visual sensor can clearly indicate the presence or absence of the small spoon in the milk powder box on the screen, so that qualified products can be packaged later.

From the iVu machine vision image in Figure 2, it can be detected that the milk powder box is the correct milk powder box, while Figure 3 shows that the iVu machine camera detects that there is no spoon, and Figure 4 shows that the iVu machine camera detects that the milk powder box is not correctly sealed.

The above is a typical application example of detecting items in packaging boxes in food and drug production. Traditional visual cameras are large in size and require computer settings when changing the environment. In response to the market demand for visual cameras in China, Banner has developed a new sensor - iVu, which is easy to operate and does not require PC settings. Its small size, powerful functions and unique appearance are especially suitable for occasions where ordinary photoelectric sensors cannot solve the problem. The visual inspection solution mainly includes two aspects: hardware - camera, controller, light source and bracket; software - control system, graphical user interface (GUI) and image analysis algorithm.
