On automated packaging lines, after labels are applied, products often show bubbles, wrinkles, missed labels, or print defects. These not only affect appearance but can make barcodes unreadable. To solve the inefficiency and inconsistent standards of manual visual inspection, Wanzhi Automation introduced the WZ-3022 CCD vision inspection machine, providing an efficient and reliable automated solution for downstream inspection.

1. Inspection pain points after labeling and our vision inspection solution

In conventional lines, inspection after labeling mostly relies on people. Long shifts cause eye fatigue, so defects such as bubbles and tiny scratches are missed. Manual inspection also makes standards hard to unify and cannot provide 100% inspection or data retention. With CCD vision labeling and downstream inspection technology becoming more common, replacing manual work with machine vision is the industry trend. A vision inspection system captures product surface images with high-definition cameras and uses algorithms to judge defects quickly, unifying inspection standards, enabling full quality data traceability, and effectively improving overall yield.

2. WZ-3022 vision inspection machine technology and specifications

To address these pain points, the WZ-3022 CCD vision inspection machine from Wanzhi Automation offers a complete solution. The model is WZ-3022, full name CCD vision inspection machine, and applicable product sizes are customized to the workpiece, fitting flexible full inspection of all kinds of small flat parts. The machine uses a Hikvision 6-megapixel industrial vision imaging system whose high-definition images reliably capture fine defects, greatly reducing missed and false detections. Inspection throughput reaches 2000 pieces per hour, effectively lowering labor costs. The system also supports one-stop multi-function inspection, simultaneously identifying appearance defects, missing parts, assembly errors, and barcode anomalies. The industrial touch-screen system makes program storage and recall easy and supports rapid switching between products for flexible production.

3. Line deployment tips and routine maintenance

For line deployment and daily operation, connect the WZ-3022 seamlessly to upstream and downstream lines such as labeling and packaging. For products prone to bubbles, add vision inspection directly after the labeling station and optionally fit a pneumatic or belt-type reject mechanism to separate good and NG products automatically for unattended inspection. In routine maintenance, clean the industrial camera lenses and light sources regularly to keep images clear; when changing product specifications, recalibrate the inspection field of view and algorithm thresholds to maintain inspection accuracy and stability.

FAQ

Can the WZ-3022 detect tiny labeling bubbles?

Yes. The machine has 6-megapixel industrial cameras and our own high-precision algorithm, clearly capturing fine surface defects including tiny bubbles, wrinkles, and edge adhesive squeeze-out, effectively preventing missed defects.

Can the inspection speed meet high-speed line requirements?

Yes. The WZ-3022 achieves throughput of 2000 pieces per hour with fully automated conveying and inspection, readily matching the pace of high-speed upstream labeling or packaging lines for efficient flow.

How does the machine handle defective products?

An optional pneumatic or belt-type reject mechanism can be fitted. When the system judges a product as NG, the reject mechanism diverts it automatically so only qualified products move to the next process.

Is setup complicated when switching the line to a different product?

Not complicated. The machine runs an industrial touch-screen control system, and inspection programs can be stored and recalled quickly. When changing products, simply recall the matching program and fine-tune the light source or camera parameters for rapid switching.
