product background

In the past, testing whether the quality of printing and packaging was qualified was mostly achieved through manual visual inspection. Not to mention the low detection efficiency, missed inspections and false inspections often occurred, and the inspection standards were difficult to unify. The emergence of testing equipment has solved the disadvantages of low efficiency of manual testing and high outflow rate of defective products. It has improved the efficiency of packaging testing and reduced labor, time and management costs.

Inspection principle

Packaging inspection of printed graphics After the production of packaging, palletizing, and labeling, the graphics and text visual inspection system will use high-performance industrial cameras to take pictures of the packaging surface from multiple angles and in all directions, and transmit each frame of the captured image to the The on-site computer analyzes and processes image information through image processing software, finds products with defective appearance, and realizes online rejection of defective products.

Inspection details

The inspection machine adopts multiple sets of high-pixel industrial cameras and high-performance stroboscopic light sources to carry out omni-directional visual inspections for product appearance defects. The equipment can realize 7*24 hours of all-weather operation, and it can be online automatically. Eliminate substandard products.The whole set of inspection equipment includes mechanical, visual electronic hardware and inspection system software. The entrance and exit of the equipment are reserved for docking positions to facilitate on-site operations.

Automatic print quality inspection Most of the inspection systems used in automatic print quality inspection equipment are to use high-definition, high-speed camera lenses to capture standard images, and then set certain standards on this basis;The CCD linear sensor converts the light quantity change of each pixel into an electronic signal. After comparison, as long as the detected image is found to be different from the standard image, the system considers the detected image to be an unqualified product. All kinds of errors in the printing process are only the difference between the standard image and the detected image to the computer. Defects such as smudges, ink dot chromatic aberration, etc. can be detected.
