Easy Operation Adhesive Dispensing Valves​ for VCM/Voice Coil Motor Application

Piezo jet valves are high-precision adhesive dispensing valves widely used in the CCM industry for VCM component assembly. Utilizing a piezo actuator, these jetting valves enable non-contact, high speed micro-dispensing of UV, epoxy, or silicone adhesives with exceptional accuracy and repeatability. Popular in key markets like China, Korea, Vietnam and India, piezo jet valves ensure consistent jetting performance for compact camera module manufacturing.

Core Advantages

• Non-contact spraying: avoid crushing tiny structures (such as coils, magnets, FPC, etc.).
• High-speed spraying to improve production capacity: adapt to the beat requirements of large-scale VCM packaging process.
• Precise glue control to ensure consistency

Main appliaction

• Magnet fixing: Magnets are bonded to the VCM housing or bracket (epoxy glue)
• Coil and housing bonding: Fix the coil assembly to ensure stable focus (epoxy glue)
• Bracket structure glue: Micro-point connection between VCM housing components (UV glue)
• FPC (flexible circuit board) fixing: Bond FPC to the housing or frame (UV glue)

FAQ

Q1: Why are piezo jet valves preferred for dispensing in VCM assembly?
A1: Piezo jet valves offer high-speed, non-contact micro-dispensing with excellent repeatability. This is ideal for VCM components, which are small, fragile, and require precise adhesive placement without damaging sensitive parts like coils or magnets.

Q2: What types of adhesives are typically used for VCM applications?
A2: Common adhesives include UV-curable adhesives for fast processing, epoxy for strong bonding, and silicone for vibration damping. The piezo jet valve is compatible with all of these due to its precise and consistent jetting capabilities.

Q3: How does the piezo jet valve improve VCM production efficiency?
A3: With jetting frequencies up to hundreds of Hz, piezo valves significantly increase throughput. They allow for automated, high-speed, repeatable dispensing without contact, reducing cycle time and minimizing rework rates.

Q4: Can piezo jet valves handle different VCM adhesive viscosities?
A4: Yes, piezo jet valves can handle a wide range of viscosities (typically 0–500000 cps) by adjusting valve parameters like jetting frequency, stroke, and nozzle diameter.

Q5: Do you have any MOQ for Piezo electric jetting valve?
A5: Low MOQ, 1PC for sample checking is available
