Label Vision
Labeling positioning and label inspection solution
For bottles, cartons, flexible packages and label materials, we connect positioning, post-label inspection, rejection and traceability into an acceptable production-line loop.
Object
Labels
Presence, offset, skew, damage, duplicates and missing labels.
Integration
PLC
Triggering, judgement, rejection, alarms and result records.
Focus
Stability
Lighting, takt, false rejects, misses and acceptance criteria.
Scenarios
For lines that need label position and product consistency
Label projects are often fast, reflective and space-constrained, requiring stable imaging, algorithm judgement and equipment linkage.
02
Post-label inspection
Inspect presence, offset, skew, wrinkles, damage, duplicate labels and missing labels.
03
High-speed rejection
Combine encoders, sensors and PLC signals to synchronize NG results with rejection devices.
System
A complete label vision station from imaging to execution
The solution selects cameras, lenses, lighting, triggering, algorithms and communication according to material, speed, space and inspection criteria.
01
Industrial cameras and lighting
Choose area cameras, ring lights, bar lights or coaxial lighting according to label material and reflection.
02
Positioning and inspection algorithms
Use edges, templates, region analysis and rules for positioning, offset, skew and defect judgement.
03
Equipment communication and traceability
Connect PLCs, rejection devices, alarms and databases while recording results, images, batches and time.
Process
Stabilize images first, then define judgement boundaries
Label inspection should evaluate normal, borderline and abnormal samples before acceptance.
01
Sample and site review
Confirm material, reflection, line speed, inspection position, false reject / miss requirements and rejection method.
02
Optics and trigger validation
Test field of view, lighting angle, exposure, trigger timing and motion blur risk.
03
Algorithm and threshold setup
Build positioning, offset, angle, damage and presence rules with tunable parameters.
04
On-site commissioning
Close the loop with PLCs, rejection devices, alarms, records and acceptance samples.
Deliverables
Deliver the inspection result and the maintenance boundary
Delivery should include hardware, parameters, exception handling and acceptance records for later maintenance.
01
Hardware and installation proposal
Camera, lens, lighting, mount, trigger and protection recommendations.
02
Parameters and acceptance samples
Key thresholds, abnormal samples, judgement logic and acceptance records.
03
Communication and records
PLC signals, result format, image retention and traceability fields.
FAQ
Common risks in label vision projects
Clarifying these topics early reduces repeated on-site tuning and acceptance friction.
Can transparent or reflective labels be inspected?
They can be evaluated, but lighting and angle tests are required. Transparent, holographic and highly reflective labels need more optical work.
Can high-speed lines be inspected reliably?
It depends on takt time, exposure, trigger accuracy, field of view and rejection distance.
Can it integrate with existing labeling equipment?
Usually yes through I/O, TCP or PLC communication, depending on existing interfaces and takt requirements.
