Strongest UV intensity class for air-cooled line type LEDs in the industry
There are types of UV curing systems with two different wavelengths (365nm and 385nm) available:
- UV intensity of 4,600mW/cm2 with a wavelength of 385nm and an irradiation distance of 10mm
- UV intensity of 4,200mW/cm2 with a wavelength of 365nm and an irradiation distance of 10mm
No water-cooling equipment necessary because the unit is fan-cooled. The compact equipment makes installation easy.
Multiple sizes available
Six sizes are available for use in various applications.
Compact size makes installation easier
The compact equipment can be installed in narrow spaces and thus provides greater flexibility when it comes to choosing an installation location.
Why is the UV intensity high?
Reason 1: The LEDs’ capabilities are maximized by the cooling structure.
Reason 2: A high light density is achieved thanks to the compact design. Furthermore, the design also enables long-distance irradiation.
Flexible UV irradiation patterns
The UV irradiation can be controlled separately for each block in the head. This allows to emit UV irradiation according to the shape of the workpiece and also reduces the power consumption because LEDs can be turned OFF in the area where UV irradiation is not needed.
The example shows the difference between two UV irradiation patterns using 6 blocks for type A (large workpiece) and 4 blocks for type B (small workpiece). By turning off block 1 and 6 for type B, the power consumption is reduced by one third.
Stable UV irradiation
- No more resin curing defects or insufficient curing of adhesives
- Temperature feedback control
- Provides UV irradiation accuracy within ±5% (at 80% UV intensity setting).
Generally, an increase in LED temperature reduces the UV irradiation output. However, the UD40 series employs a Panasonic original head-cooling mechanism to suppress temperature increases. In addition, a temperature sensor is built into the head to constantly monitor and feed back temperature information. This leads to an excellent UV irradiation stability within ±5% for an output of up to 80%. This is ideal for high-quality, precise adhesion applications.
Typical characteristics (an ambient temperature of 25°C)
External access control
A PLC or another external device can be used to control the UV irradiation.
The duration of the UV irradiation can be limited.
Operating time and temperature display functions
The number of hours of lighting is counted for each LED block in the head. When a specific number of hours is reached, the LED replacement period is indicated through the controller's external output and panel display. In addition, because the head has a built-in temperature sensor, the LED temperature during operation can be displayed. If an abnormal temperature is detected, the controller sends a warning through its external output and panel display. These functions ensure safety and improve productivity.
Long-life, economical LEDs
The UV curing system with LEDs features an extremely long light-source life span compared to the lamp-type curing system. While the estimated life span of a lamp is 1,500 hours, the estimated life span of the LED is 15,000 hours (at an ambient temperature of +25°C).
Furthermore, unlike the lamp type that remains on at all times, the LED type can be turned on only when UV irradiation is needed. If the irradiation on/off time ratio is 1:4 (process takt time = 5, irradiation time = 1), this calculates to a life span of approximately 75,000 hours (at an ambient temperature of +25°C), which can drastically reduce running cost and maintenance man-hours.
Low power consumption at 100W per LED
Even when six blocks in a single head are turned on, the maximum power consumption is 650W (at 200V AC). This effectively reduces power consumption and CO2 emission. Since less heat is generated than with the lamp type, even when the UV curing system is used in a small clean room, the increase in room temperature is small. This reduces the power needed for air conditioning.
Eco product compliant with CE, RoHS, etc.
Unlike lamps, LED heads do not contain mercury. UD40 conforms to CE Marking regulations, the RoHS Directive, and Management Methods for Controlling Pollution by Electronic Information Products (China RoHS), ensuring environmentally safe use.
