In modern food packaging automation production, various inspections and measurements are involved. Such as the printing quality inspection of the cap, the product packaging characters, barcodes, labels, etc. The common feature of this type of application is continuous mass production and high quality appearance.
In the production of beverages, the production date of the day of printing needs to be printed. There are generally two types of printing on the current production date: one is a printer, and the black characters are printed on the bottle cap or the bottle body; the second is a laser marking machine. Also known as a laser printer, a colorless production date with a certain depth is engraved on the neck of the bottle.
The first method is more flexible, but often the scene of the printer nozzle is blocked, resulting in incomplete characters or missing characters; the second method is easy to print overlapping, missing, or missing during the coding process. Phenomenon; for most of the above problems, the factory uses manual methods for inspection, but this will greatly affect the production speed.
Xinwei Vision can carry out quality inspections on the coded products, sorting and rejecting code quality defects such as font ambiguity, code distortion, character errors, and dot characters that cannot be connected in the product to ensure the quality of all products. Consistency. Take the mineral water date as an example:
1, bottle cap printing character detection
Bottle cap printing characters
The above characters are printed on the arc surface of the bottle cap. When the light is turned on, there will be a phenomenon that the middle bright and both sides are dark. At the same time, the concave and convex stripes are also obvious. Generally, visual packaging testing is somewhat difficult. After many years of hard work, Xinwei Vision can do the following: effect:
Improved image cap characters
After the improvement, it can be clearly seen that the background of the character is highlighted, the character is black, and the overall feeling is on a plane, so that the visual detection is more convenient, and the detection effect is as follows:
Software Detection Interface NG Software Detection Interface OK
2, outer printing character detection
On the outer package, the bar code will be printed on the product itself and the label so that the company can establish a product tracking system and meet the requirements of the enterprise to collect product bar code information in real time. With its excellent reading ability, Sunny Vision System can accurately and quickly read characters on various packaging materials.
As food quality standards become stricter and stricter, not only character printing needs strict inspection, but also the reading and verification of barcodes and two-dimensional codes becomes more and more important in many detection processes.
Xinwei Vision has been focusing on machine vision system solutions for fifteen years. Its intelligent machine vision software has excellent bar code and two-dimensional code recognition capabilities and can correctly read various types of bar codes. At the same time, Xin Wei Vision can also solve all machine vision problems for you, full service, professional and efficient.
