360° Label Inspection Machine (Model: DY‑FY‑4)
2. Main Advantages & Features
2.1 DAVUE AI Vision Industrial Intelligent Quality Inspection System
Independently developed with world‑leading AI software architecture and full independent intellectual property rights. Equipped with deep‑learning‑based AI inspection technology and complete algorithm system.
Combined with conventional quality‑inspection algorithms, it identifies subtle differences among samples from multiple dimensions, covering application scenarios including product defect detection, classification, measurement and monitoring.
Inspection throughput reaches 200 000 objects per hour. It realizes ultra‑high‑speed, high‑precision real‑time identification and rejection of defective products, so as to achieve precise quality control in production and guarantee product quality.
The inspection & control system adopts modular design, high‑efficiency image‑processing algorithms and distributed computing architecture, featuring high‑speed inspection, high reliability and great adaptability.
Good expandability and interoperability; flexible modular configuration. New inspection modules and functions can be added on the existing control center according to production & customer requirements to reduce future equipment investment. It supports communication with customer‑existing MES production‑management systems for Industry 4.0 & smart‑factory interconnection.
2.2 World‑class Hardware Configuration
Adopts high‑resolution CCD area‑scan cameras, high‑definition industrial lenses and optical glass with light transmittance＞98 %, to capture sharp, high‑resolution distortion‑free raw images. High‑brightness long‑life LED cold light sources; brightness maintains stable after 100 000 running hours.
Deep‑learning‑powered AI inspection delivers faster & more stable calculation than embedded computing boards inside smart cameras. Genuine Windows‑based software with user‑friendly intuitive GUI.
Straight‑through signal & image transmission without intermediate repeaters, minimizing signal degradation & distortion. It supports ultra‑high‑speed lossless data transmission to ensure valid image processing & output signals, laying the foundation for extremely low false‑rejection rate and escape‑rejection rate.
2.3 Systematic Equipment Maintenance & Operation Support
Built‑in self‑diagnosis, debugging guidance, operation status display, system help and operation log functions. Product recipe & inspection‑algorithm switching can be finished within 10 minutes. Intuitive workflow, easy‑to‑learn operation.
Complete system‑help functions for storage, query and timely updates. SOPs for system operation, equipment maintenance and technical documents are accessible locally on machine, including troubleshooting guides for common faults.
On‑board diagnostic & remote‑maintenance function for real‑time global technical support & remote commissioning.
Rich optional functions for adaptation to different production‑line processes. Multi‑source collected data can be tracked, aggregated, correlated and traced for precise process control & data management.
Multi‑year production‑data storage; data export for third‑party use. Customizable & printable production reports for customer quality analysis.
2.4 Control Cabinet & Inspection‑unit Cabinet Configuration
- Touch‑screen control cabinet with IP65 industrial protection rating.
- Multi‑channel audible‑visual alarm beacon to indicate equipment status and trigger audio‑visual alerts upon abnormalities.
- Control cabinet constructed of SUS304 stainless steel, manufactured to Rittal (Germany) standards and equipped with positive‑pressure protection, suitable for various complex working conditions.
- The inspection cabinet adopts an “over‑bridge” non‑contact design above the existing production‑line conveyor, compatible with various conveyor configurations.
- Fully‑enclosed inspection cabinet provides protection for cameras, light sources, lenses and precision optical components.
- Light‑blocking glass fitted on both ends of inspection cabinet to eliminate interference from natural ambient light on inspection accuracy.
- Bottle format change is realized by turning the adjusting hand‑wheel for overall vertical lifting of the inspection system; graduated scale is provided for quantitative recording of height positions.
- The rejector is adjustable vertically and front‑to‑rear to ensure defective bottles are stably ejected to the designated position.
3. Inspection Functional Modules
- Label Inspection Module
(This solution applies only to non‑transparent labels. For transparent labels, only label presence / absence inspection is supported.) Detects missing labels, excessive high / low label position, skewed labels, adhesive‑tape splices, inverted patterns and misaligned labeling.
Hardware: 4 sets industrial cameras; 4 sets optical components & control assemblies
- Pneumatic Rejection Unit
Ejects defective products according to trigger signals sent by the system. Rejection rate: 72 000 units / hour Equipped with high‑speed air cylinder.
4. Inspection Specifications & Criteria
| Inspection Type | Inspection Item | Inspection Accuracy | Rejection Accuracy | Mis‑identification Rate |
|---|---|---|---|---|
| Label Inspection Module | Missing label | No label | 100 % | ≤0.02 % |
| High‑position label | Offset above center ≥ 2 mm | ≥99.95 % | ≤0.02 % | |
| Low‑position label | Offset below center ≥ 2 mm | ≥99.95 % | ≤0.02 % | |
| Tape splice | Non‑transparent tape splice (Width × Length ≥ 20 mm × 20 mm) | ≥99.99 % | ≤0.02 % | |
| Skewed label | Horizontal tilt ＞ 3° | ≥99.95 % | ≤0.02 % | |
| Inverted label | Label upside‑down | ≥99.95 % | ≤0.02 % | |
| Mis‑aligned labeling | Incorrect label cutting position, vertical offset ＞ 5 mm | ≥99.90 % | ≤0.02 % |
Technical Remarks
- Label inspection requires dry cap surface. Residual water droplets on bottle exterior will affect inspection results and cause false rejection.
- Bottles must pass freely through the inspection system without squeezing. Bottle‑to‑bottle spacing shall be at least 1.2 × bottle diameter to guarantee full 360‑degree inspection.
- Product conveying shall be stable without bottle jitter or tilting; conveyor‑chain speed must be constant without fluctuation.
