Four Head UV LED Spot Curing System Delivering High Irradiance Low Heat Output for Camera Module Assembly

Four Head UV LED Spot Curing System for Camera Module Assembly

Product Overview

This four head UV LED spot curing system concentrates high irradiance UV energy into four small curing spots that can be triggered independently or together. Each head runs on its own channel with separate intensity and exposure time, so a single bench can cure lens bonding, housing sealing and FPC reinforcement in one cycle. Air cooled LED heads keep heat away from the optical stack, which protects lens modules, image sensors and flexible circuits from thermal drift.

Key Features

• Four independent curing heads - each channel has its own intensity, timer and trigger mode, and can be sequenced or fired simultaneously
• High irradiance spot output - concentrated UV energy at the curing point shortens cycle time and cures deep shadow areas of the adhesive
• Low heat generation - air cooled UV LED heads plus a finned heatsink keep the workpiece near room temperature, protecting lenses and image sensors
• Quick change lens tube - 3mm, 5mm and 8mm spot lenses screw on without tools, so one system covers several product models
• PLC and I/O trigger - 24V I/O, level trigger and switch signal input for integration with active alignment stations and automated lines
• LCD parameter storage - 10 process recipes with intensity, time and channel selection stored in memory
• Foot pedal and hand trigger - dual operation modes for manual bench assembly and semi automatic production
• 20000 hour LED life - stable output over long production runs with no lamp replacement cost

Frequently Asked Questions

Q: Can the four heads be used at the same time?
A: Yes. The channels can be fired simultaneously, in a programmed sequence, or independently by external trigger, depending on the assembly process.

Q: How do you control heat on the workpiece?
A: The LED heads are air cooled and the optics use a cold mirror and quartz lens, so radiant heat reaching the part is low. Curing can run continuously without heating the lens barrel.

Q: Is the system compatible with an active alignment machine?
A: Yes. The 24V I/O and level trigger inputs accept standard machine signals, and the PLC interface reports channel status back to the host controller.

Q: Which wavelength should I choose for camera module adhesive?
A: Most camera module UV adhesives are formulated for 365nm or 395nm. Send us the adhesive datasheet and we will confirm the matching head and lens.
