Double-groove guidance gives this wheel disc stronger edge control than a standard flat contact wheel. The 25 Double Groove Wheel Disc helps keep PCB, FPC, and LCD panels centered through long conveyor spans, reducing snaking, drift, and transfer instability.
Core Advantages: Double-groove tracking structure, rubber/PU damping surface, chemical resistance, and stable edge-holding performance.
Selection Recommendations: Choose the suitable groove depth, rubber hardness, bore size, and shaft fit based on board thickness, edge-clamping needs, and conveyor layout.
Applications: Horizontal etching lines, developing machines, stripping equipment, rinsing and drying tunnels, black-hole treatment modules, and positioning mechanisms.
Stable Operation Guarantee: Helps reduce board wander, nozzle collision, lateral drift, line jams, and scrap caused by unstable panel alignment.
Dual-Track Stability for Flawless PCB Alignment. In high-precision wet-process applications, tracking deviation is often the culprit behind inconsistent etching and developing results. The 25 Wheel Disc with Double Groove is specifically engineered to cradle the board edge, providing dual-point stability that prevents lateral drift during transport. This design eliminates the common “snaking” effect experienced in long conveyor spans. By combining a structural guide mechanism with vibration-dampening materials, this wheel ensures consistent, straight-line movement, protecting your product from mechanical damage and ensuring the high-precision alignment required for today’s dense circuit board architectures.
Precision Geometry Meets Mechanical Compliance
· Dual-Track Security: The double-groove geometry provides superior tracking stability, effectively locking the board edge in place to prevent skewing.
· Elastomeric Damping: The rubber-coated contact surfaces absorb mechanical energy, minimizing vibration and preventing physical deformation of the board edge.
· Chemical Inertness: Built with materials resistant to common etching and developing chemistries, ensuring the surface finish does not degrade or introduce contaminants to your process.
Configurable for Diverse Transport Requirements
· Groove Depth Variations: Adjust the track depth to accommodate different board thicknesses and edge-clamping standards.
· Material Durometer: Choose from varying rubber hardness levels to balance grip intensity with surface pressure sensitivity.
· Shaft Compatibility: Precision-machined bores designed for a secure, zero-backlash fit on standard conveyor shafts.
The double-groove disc is a vital component for PCB, FPC, and LCD manufacturing equipment, primarily where precise board guidance is required through complex wet-process environments. These are installed within long-span conveyor segments of horizontal etching, developing, and stripping machines, as well as glass cleaning and black-hole treatment modules. By maintaining rigid spatial control, these wheels protect against cross-contamination caused by board misalignment. Their robust design supports high-speed operation in high-volume production facilities, ensuring that panels move through critical treatment zones with total consistency and stability.
In large-scale horizontal etching lines, board wander is a persistent risk that leads to uneven etching rates across the panel. The double-groove design forces the board to remain perfectly centered under the spray nozzles, optimizing the chemical reaction uniformity. This directly improves the consistency of ORP-controlled processes and reduces the risk of under-etched traces. For an equipment maintenance supervisor, this translates into fewer line jams and a measurable reduction in scrap rates caused by physical handling errors.
When used in high-speed, multi-stage rinsing and drying tunnels, these wheel discs maintain the vertical position of the panel despite varying hydrodynamic forces. By keeping the board stable, they prevent collisions with spray nozzles or air-knives, preserving the uptime of the entire module. The investment in double-groove technology provides a high ROI through increased equipment reliability and decreased labor time required for manual board alignment and troubleshooting, ensuring your production flow remains uninterrupted.
