UJ30/35 LED spot-type UV curing systems

  • UJ30/35 LED spot-type UV curing systems

Aicure UJ30/35

The compact UJ30/35 controllers can be equipped with up to four individually controlled LED heads and, due to their small size, can be easily integrated into existing systems. Different types of UV-LED heads are available with an irradiation wavelength of either 365nm, 385nm or 405nm. Because cooling occurs naturally (without a fan), the systems are well suited for use in clean rooms. To provide the best possible irradiation for the application in question, twelve different lenses are available for the heads. You can control the heads by either using the user-friendly panel on the front of the controller or via the digital interface. The UJ35 additionally offers an RS232 interface, which can be used for configuration and to create backups.

Thanks to our long experience with curing systems and the LED technology involved, we were able to create a system with the UJ30/35 that requires substantially less energy than conventional curing systems and one that offers many other advantages besides high intensity.

LED technology

Each UJ30/35 LED head is equipped with a high-power UV LED. This means the heads enjoy a lifetime more than 20,000 hours! Moreover, the LEDs neither require a warm-up nor cooling-off period, nor will frequently switching them on and off shorten their lifetime.

Your benefits:

  • Components subjected to minimal thermal strain
  • LED heads require no warm-up time
  • Long lifetime

High-power irradiation

The UJ30/35 LED heads offer a sensational UV irradiation performance of up to 20,900mW/cm2 per head.

Your benefits:

  • UV LED head – max. 20,900mW/cm2
  • Short irradiation time, i.e. high tact frequency
  • Optimized design for heat emission

Programmable with four independent heads

With a lamp type model, one process requires one irradiation unit. With UJ30/35, one unit can be used for up to four processes due to its four individually controllable LED heads. The irradiation can be programmed to control the UV radiation power and time depending on the resin and curing application, supporting high-quality, high-precision bonding with minimum shrinkage. In addition to the simple irradiation mode whereby irradiation is emitted continuously at a constant intensity, up to seven different irradiation patterns (product types) can be programmed for each of the four LED heads. This includes the step-up mode, in which the intensity is changed over time, and the interval mode, in which irradiation is performed at specified intervals.

Your benefits:

  • Flexibility of virtually four independent curing devices in one
  • High-precision curing at low temperatures

Easy and quick installation

The extremely compact UJ35 controller can be set up either with complimentary PC software or directly via the controller’s well designed front panel. In either case, setting up the UJ35 is just a matter of minutes. Being equipped with a digital I/O interface with detachable terminal blocks, it is easy to connect UJ30/35 to an external PLC or PC. The UJ35 additionally offers an RS232C port. The LED heads have a diameter of only 12mm and can be easily secured with an optional jig. The heads' electrical (not fiber) cables can be extended up to 10m, permit a bending radius of 33mm, and can be bent 10,000,000 times or more!

Your benefits:

  • Easy, cost-saving installation
  • Intuitive operation
  • Compact design
  • Suitable for installation on moving parts
  • Setting software for UJ35

Stable UV intensity

Each UJ30/35 head is equipped with a temperature sensor, which is continuously monitored by the controller, keeping UV irradiation stable within a range of  +/-3%.

Your benefits:

  • UV irradiation accuracy +/-3%

Efficient curing without temperature increase

The irradiation beam of the UV LEDs does not include infrared rays, hence the temperature rise of the cured workpieces is minimal.

Your benefits:

  • Components subjected to minimal thermal strain
  • Highly efficient curing by narrow spectrum of +/-5nm

UV intensity measurement

The optional UV sensor for UJ35 measures the actual irradiation intensity of an LED head. Because the UV sensor measures just 5mm in height, the irradiation intensity can be measured directly at the work station or in the system without having to disassemble the equipment. When the intensity deviates too much from that required, the system can automatically adjust it as necessary. The advantages are clear: curing quality is consistent and process reproducibility very good.

Your benefits:

  • Consistent curing quality
  • Easily reproduced

Multiple safety features

This product has a function to detect breaks and short-circuiting of the LED head. The LED is automatically turned off if it overheats. Moreover, an emergency stop of UV emission is provided via a signal on the rear of the controller.

Your benefit:

  • Safe and durable operation

Fanless design

UJ30/35 employs no electromechanical components. Even cooling is realized without a fan.

Your benefits:

  • For use in clean rooms.
  • Parts not subject to wear & tear. No maintenance.
