ZONESUN ZS-STB3 Automatic Vision Positioning Labeling Machine CCD Camera Guided Smart Visual Alignment
The ZONESUN ZS-STB3 is a fully automatic vision-positioning labeling machine designed for high-precision cap labeling. Running at 22–25 pcs/min, it uses a camera-guided algorithm to detect cap orientation and applies labels at the exact target angle. With PLC-based coordination, XYZ servo slide, rotary labeling head, and stable bottle alignment, it delivers repeat-accurate, premium-grade labeling performance for perfume and cosmetic packaging lines.

VISION PROCESSING
Processes real-time image data to identify cap position and orientation, sending precise control signals to ensure accurate and stable automated cap placement.
XYZ THREE AXIS SLIDE
Delivers precise X/Y/Z servo positioning to align the labeling head with camera-detected cap angles, ensuring stable, accurate labeling.
ROTARY LABELING HEAD
Applies labels with servo-driven rotary precision, aligning each label to the camera-detected cap position for repeat-accurate, premium-grade labeling.
LABEL FEEDING
Ensures smooth, stable label delivery and precise peeling, providing the rotary head with consistent label supply for repeat-accurate cap labeling.
ALIGNMENT GUIDE
Aligns bottles into a straight, stable horizontal line on the conveyor, ensuring optimal camera detection and precise cap-labeling accuracy.

Why choose the ZS-STB3?
-
CCD Vision Positioning — ±0.1 mm Accuracy: Industrial camera continuously captures cap orientation in real time, enabling the servo system to correct label placement to within ±0.1 mm — critical for luxury packaging where label misalignment is unacceptable.
- Automatic Cap Orientation Recognition: Intelligent algorithm identifies the reference mark or feature on each cap automatically, eliminating the need for manual pre-orientation or mechanical star-wheel alignment fixtures.
- XYZ Servo-Driven Precision Adjustment: Three-axis servo system dynamically compensates for cap position variation in real time, maintaining consistent label placement across the full production run without operator intervention.
- Rotary Labeling Head: Rotary applicator conforms label smoothly to curved cap surfaces, preventing air bubbles, wrinkles, and edge lift on small-diameter caps typical in perfume and cosmetic packaging.
- PLC Touchscreen Control: Intuitive HMI allows operators to store and recall product recipes, adjust label position offsets, and monitor production counts — reducing changeover time between SKUs.
- 22–25 pcs/min Stable Throughput: Consistent speed across the full shift without warm-up degradation, supporting integration into semi-automated or fully automated cosmetic packaging lines.
- Reduced Rejects & Label Waste: Vision-guided correction reduces mislabeled units to near zero, lowering material cost and rework labor on high-value packaging components.
- Customizable Product & Label Dimensions: Cap diameter, height, and label size ranges are configurable to accommodate diverse bottle and cap formats beyond the standard 56 mm / 145 mm specification.
Applications
- Perfume & Fragrance Packaging: Precision cap labeling for glass perfume bottles where brand logo and decorative labels must align exactly to embossed or printed cap features.
- Luxury Cosmetics: Foundation, serum, and skincare cap labeling for premium brands requiring zero-defect label placement on high-gloss or metallic cap surfaces.
- Essential Oil & Aromatherapy Products: Small-cap labeling for roller-ball and dropper bottles where label size and placement consistency directly affect retail shelf appeal.
- High-End Personal Care: Shampoo, conditioner, and body care pump cap labeling for prestige personal care brands with strict packaging quality standards.
- Pharmaceutical Packaging: Cap labeling for prescription and OTC bottles requiring tamper-evident or regulatory label placement with documented positional accuracy.
- Contract Packaging & CMOs: Multi-SKU cap labeling operations where rapid recipe changeover and consistent quality across different cap formats are essential for client SLA compliance.
