The ribbon slitting machine with visual inspection realizes zero-defect slitting through intelligent technology, especially suitable for electronics, label printing and other industries that require high precision. The following are its core technologies and solutions:
First, the core composition of the system
1. High-precision slitting module
◦ Servo-driven slitting tool holder, cutting accuracy ± 0.1mm.
◦ Pneumatic/hydraulic pressing system to avoid ribbon sliding between layers.
2. Visual inspection system
◦ Industrial cameras: line/area scan cameras (e.g. more than 5 million pixels) with high-brightness LED light sources.
◦ Inspect contents: edge burrs, stains, uneven thickness, printing defects (e.g., color difference, missing characters).
3. Intelligent control center
◦ Integrated PLC+ IPC to run AI algorithms (such as YOLO or CNN) to analyze images in real time.
◦ Support data exchange with MES/ERP system.
Second, the key technology to achieve zero defect slitting
1. On-line full inspection and automatic rejection
• 100% full-frame scanning: The camera captures the ribbon surface at ≥200fps with a resolution of 10μm/pixel.
• Defect classification: Distinguish defect types such as scratches, bubbles, and foreign objects through deep learning.
• Real-time sorting: mark the defective sections, and automatically reject them by the robotic arm or air spray device after slitting.
2. Adaptive slitting control
• Dynamic web tracking: The vision system detects the edge position of the ribbon and feeds back to the web guiding mechanism (such as EPC) with an accuracy of ± 0.05mm.
• Closed-loop tension control: Maintain constant tension through magnetic particle brake + tension sensor to avoid tensile deformation.
3. Dust-free and anti-pollution design
• Enclosed cutting chamber: built-in HEPA filtration system, cleanliness up to ISO Class 6.
• Static Elimination: The ribbon is treated with an ionic air bar before unwinding to prevent dust adsorption.
Third, intelligent advanced functions
1. Process self-optimization
◦ Automatically adjust the knife pressure, speed and other parameters according to the ribbon material (such as PET, silver).
◦ Historical defect data statistics and process improvement reports.
2. Predictive maintenance
◦ Monitors insert wear (edge burr rate is analyzed by image) and indicates when to change.
3. 3D visual extensions
◦ Optional laser profiler to detect ribbon thickness uniformity (e.g., ± 2 μm accuracy).
Fourth, industry application cases
• Electronic tag ribbon: ensure that there is no cutting residue in the RFID antenna layer to avoid the risk of short circuit.
• Thermal transfer ribbon: blackness value consistency detection after slitting to ensure printing quality.
Fifth, the comparative advantages with the traditional slitting machine
index | Traditional slitting machine | Visual inspection intelligent slitting machine |
Defect detection rate | ≤70% (manual sampling) | ≥99.9% (full inspection) |
Slitting accuracy | ±0.3mm | ±0.05mm |
Scrap | 3%~5% | <0.1% |
Data traceability | not | Record the defect map of the whole process |
6. Implementation recommendations
1. Selection configuration: Select the hardware according to the width of the ribbon (e.g., 10mm narrow ribbon requires a higher resolution camera).
2. Light source optimization: Use coaxial or polarized light sources for highly reflective ribbons.
3. Verification test: Calibrate the sensitivity of the system with a standard defect sample before slitting.
Through the deep integration of visual inspection + AI, this type of slitter can greatly improve the yield and automation level of ribbon production, especially suitable for fields with strict reliability requirements.
