Highest power and flexibility in adhesive curing

06-02-2023 | DELO | Industrial

DELO has created a line lamp for curing adhesives and other multi-functional polymers. DELOLUX 301 is ideal for highly automated processes in small and narrow production lines. The lamp provides the highest curing speeds and excellent flexibility for integration into production lines, like those found in consumer electronics assembly. For example, it can also be used in the lamination of thin-film solar cells.

With the addition of this line lamp to its portfolio, the company adds another form factor to its wide variety of area and spot lamps. Thanks to its high intensity of up to 30W/cm², the device facilitates maximum speeds for curing adhesives and other multi-functional polymers and provides large working distances of up to 100mm from lamp to components. The lamp's compact lamp head dimensions, measuring 42.7mm x 13mm x 67.2mm, also add to a high degree of flexibility for integration into production systems.

The lamp head produces a linear irradiated area of 38.7mm x 8.45mm. It can be operated as a single head or be seamlessly joined to form a larger array. When the lamp heads are combined in up to three directions, users may readily implement individual and homogeneous exposure geometries. For example, a wide row of lamps can be employed for the roll-to-roll lamination process of flexible thin-film solar cells, where adhesives, such as the company's PHOTOBOND LP4115, are often required to protect cells made of organic materials and perovskite from humidity ingress.

In its standard variant, the device is offered with water cooling with optimised water flow, ideal for clean rooms. The lamp has wavelengths of 365nm, 400nm and 460nm, making it ideal for UV-curing and light-curing products. Its service life is more than 20,000 hours.

This plug-and-play lamp head is controlled and supplied with power through the base units of the DELOLUX pilot A series, which are offered as touch and PLC-capable models. These models feature automatic temperature compensation so that the LEDs provide constant intensity even as they heat up.
