CSD PET Preform Vision Inspection System Optical Camera Checking Machine

CSD PET Preform Vision Inspection System Optical Camera Checking Machine

At present, the general PET beverage filling production line is composed of a series of production equipment and corresponding production processes such as blow molding machines, filling machines, coding machines, labeling machines, case packing machines, and palletizing machines. In many manufacturers, A large number of workers will be arranged to inspect products in the preform, filling, sleeve labeling, packing and other links. With the rising labor prices, manufacturers have caused a lot of pressure on labor costs. Therefore, the use of machines to replace manual quality inspection of products has become an urgent need for manufacturers.

Equipment Configurations

It has become an urgent need for manufacturers to use machines to replace manual quality inspection of products. KEYE, as a well-known machine vision inspection equipment research and development enterprise in China, has rich experience in providing machine vision inspection solutions for all walks of life. At present It has been able to provide a complete whole-line inspection solution to replace the manual product inspection work of each process.

Camera Layout

The defects of the preform usually appear in the mouth, shoulder and bottom. The preform inspection machine adopts multiple high-resolution CCD cameras, which can detect various defects in the mouth, shoulder and bottom of the preform. Comprehensive inspection. Among them, placing a camera above the mouth to collect the mouth image can check the bottle mouth flash, bottle mouth gap, mouth black spots and other defects.

A camera is placed above the mouth to capture the images of the inner wall of the mouth to check the black spots, dirt and other defects on the bottle wall, and 3 cameras are placed on the side of the screw mouth at intervals of 120 degrees for various sizes, black spots, and bottle shoulder areas. A 360-degree inspection without blind spots is carried out for thick sutures, burrs, and steps. A camera is placed above the mouth to capture the image of the bottom of the bottle embryo to check for defects such as black spots and poor nozzles. The schematic diagram is as follows:

Inspection Details

The design scheme uses high-pixel industrial cameras and high-performance strobe light sources to conduct all-round visual inspection for the appearance defects of products. The inspection speed is 60-100 pcs/min, and the equipment can operate 24 hours a day. Products can be automatically rejected online.

The whole set of vision machines includes mechanical parts, visual electronic hardware and vision system software. The entrance and exit of the inspection machine can be integrated with the customer's on-site conveyor line, and can be connected with upstream and downstream production equipment according to the specific production needs of the customer's site.
