In the automated production of electronic accessories, signage color cards, and small plastic and hardware parts, problems such as appearance defects, missing parts, and assembly errors on sheet materials are often missed because of human visual fatigue. How can inspection standards be unified and efficient fully automatic 100% inspection be achieved? This article, together with Wanzhi Automation’s WZ-3022 CCD vision inspection machine, discusses upgrade solutions for small sheet part quality inspection.

I. Pain points of conventional manual inspection and the automated 100% inspection solution

In batch production of small sheet parts, conventional manual inspection faces pain points such as low efficiency, inconsistent standards, and fatigue-induced missed defects. As output requirements rise, manual visual inspection can no longer meet modern factories’ requirements for quality consistency. Wanzhi therefore launched the WZ-3022 CCD vision inspection machine. It is an inline vision quality inspection system designed for automated 100% inspection of small sheet parts. It integrates automatic conveying, image acquisition, intelligent judgment, and data storage, and can simultaneously identify multiple defect types such as surface printing defects, missing components, assembly errors, and barcode abnormalities, solving the missed-inspection problem at its source and unifying inspection standards.

II. WZ-3022 core technology analysis and production line application

The WZ-3022’s core advantage is the deep integration of high-accuracy imaging and intelligent algorithms. The machine is equipped with a Hikvision 6-megapixel industrial vision imaging system whose high-definition imaging reliably captures subtle defects, greatly reducing missed and false inspections. It also runs a self-developed high-accuracy inspection algorithm that ensures the accuracy of multi-dimensional combined inspection, so a single machine can simultaneously detect missing material, printing defects, and assembly errors.

For system operation and line compatibility, the machine uses an industrial touch operating system whose inspection programs can be stored and recalled quickly, making changeover simple. In practice, especially on complex lines that include a CCD vision labeling process, the WZ-3022 connects seamlessly to the upstream labeling machine to re-verify the appearance, position, and barcode after labeling. The machine is of modular design and the applicable product size can be customized to the workpiece. In addition, an optional pneumatic or belt-type automatic defect rejection mechanism automatically sorts good and NG products, achieving unmanned inspection.

III. Key selection points and operating advice

When introducing the WZ-3022 for a line upgrade, companies should focus on the following selection points. First, clarify the inspection requirements: based on the product’s specific dimensions and material, ask Wanzhi Automation for a customized inspection field of view and conveying length so the machine interfaces perfectly with the existing automated line. Second, assess throughput matching: the machine’s inspection efficiency reaches 2,000 pcs per hour and one machine can replace several inspectors, so plan the number of machines according to actual daily output.

In practical operation, we recommend making full use of its end-to-end quality traceability function. The industrial control system automatically records the inspection image and judgment data for every product, which supports later quality reviews and customer complaint traceability. For batch quality inspection scenarios such as electronic accessories, signage color cards, and small plastic and hardware parts, properly configuring a defect rejection mechanism can further improve line automation and yield.

FAQ

1. Is changeover setup complicated on the WZ-3022 CCD vision inspection machine?

No. The machine runs an industrial touch operating system whose inspection programs can be stored and recalled quickly, making changeover simple and supporting fast switching among multiple products.

2. How does the machine connect to existing labeling or packaging lines?

The machine is of modular design, with inspection field of view and conveying length customizable to the customer’s product dimensions, so it connects seamlessly to upstream and downstream automated lines for labeling, film lamination, and packaging.

3. How is inspection data used for quality traceability?

The machine conveys and inspects automatically throughout, and the industrial control system automatically records and stores the inspection image and judgment data for every product, supporting later quality reviews and customer complaint traceability.

4. Does the machine support automatic defect rejection?

Yes. Expansion functions are comprehensive: a pneumatic or belt-type automatic defect rejection mechanism can be added as needed to automatically sort good products from NG products.
