AI Artificial Eyes Quality Control System For Plastic Bottles & Preforms

In recent years, the safety of food and medicine has become a hot topic in today's society. Therefore, it is very important to strictly control the hygiene in the production process and ensure the safety of food and medicine. In recent years, with the rapid development of packaging technology in food, medicine and other industries, the requirements of manufacturing enterprises for product packaging quality testing are also getting higher and higher. PET preforms are semi-finished products of beverage packaging bottles, which inevitably have defects in the production process. The preform currently has problems such as broken support ring, flash, hollow, lack of glue, air bubbles, broken bottle mouth, oval, impurities, etc., which directly or indirectly cause the unqualified final product and bring huge losses to the enterprise. How to reject defective bottles before canning is an important topic in PET bottle production.

Inspection principle

When the PET bottle preform enters the inspection machine, the photoelectric sensor triggers the signal, and the inspection system starts to track the product and prepares for image acquisition. Under the positioning of the system tracking program, it is judged that the bottle has reached the predetermined position, and the system sends out light source and image acquisition instructions. With the assistance of a specific light source, the system will capture images in real time.

After the image acquisition is completed, it will be handed over to the image processing module for identification and algorithm analysis. , judge whether the product is qualified and transmit the signal to the control system to prepare to reject the unqualified products. When the tracking program detects that the product reaches the rejection position, the control system notifies the rejection mechanism to carry out the rejection action for the defective product.

Equipment Overviews

The overall detection equipment is equipped with 10 sets of high-pixel industrial cameras to comprehensively detect the appearance defects of the outer side of the bottle preform, the opening of the preform and the bottom of the preform. After the system collects the sample image, the image processing software is compared with the standardized sample to determine the good product and the bad product.

Key technology

1)Camera:Selected high stability, high transmission capacity and high anti-interference ability of industrial-grade cameras. Industrial cameras are also commonly known as cameras. Compared with traditional civilian cameras (cameras), they have high image stability, high transmission capacity and high anti-interference ability.CCD is currently the most commonly used image sensor in machine vision. It integrates photoelectric conversion, charge storage, charge transfer, and signal reading, and is a typical solid-state imaging device. The outstanding feature of CCD is to use electric charge as a signal, which is different from other devices that use current or voltage as a signal. Such imaging devices form charge packets through photoelectric conversion, and then transfer and amplify output image signals under the action of driving pulses.

2)Lens:The industrial lens is a very important imaging component in the machine vision system. If the system wants to fully play its function, the industrial lens must be able to meet the requirements.The telecentric lens selected when inspecting the bottle mouth can correct the parallax of traditional industrial lenses. It can make the magnification of the obtained image not change within a certain object distance range. is a very important application. Due to its unique parallel light path design, telecentric lenses are very suitable for high-precision machine vision applications.
