Conveyor belt UVLED tunnel furnace lightweight, suitable for the use of UV curing. The light source USES LEDUV light source, cold light source, no infrared heat radiation, low temperature curing to prevent the thermal deformation of the formed products, improve the bonding accuracy. Unique UVLED array packaging technology, good irradiation uniformity, excellent uniformity of the edge and center irradiation intensity. The height of the light source is adjustable, and the speed of the conveyor belt is displayed by LED, which is convenient for process management. The machine body is made of high-density teflon steel, which can reduce the vibration during transportation. With a variety of UV wavelength and power LED light source, suitable for different UV curing process.
