UVLED What are the common failures and causes of curing machines? UVLED curing is a highly environmentally friendly curing and drying method currently on the market. Its working principle It emits pure ultraviolet light through the UVLED chip. UV glue , UV ink and other UV coating coatings are irradiated to achieve fast and good curing effects. The uv light source can instantly light up the UVLED curing machine and emit ultraviolet light with a main peak of about 360nm (there are also other wavelengths) to complete the curing task. The whole process usually takes only a few seconds and is not as harmful to the environment as mercury lamps.
However, we will encounter some problems more or less during the use of UVLED curing machines. The reasons may be improper operation or problems with the curing machine accessories themselves. Yongcheng Optoelectronics has compiled some common problems and solutions here for your reference.
Possible faults, causes and solutions
1. UVLED lamp beads do not light up or self-extinguish
Analysis of one of the reasons: insufficient air cooling
Solution: Clear the air duct and clean the fan wheel debris
Analysis of the second reason: UVLED lamp beads will produce a certain degree of attenuation as they are used longer.
Solution: The lamp beads can be replaced appropriately
Analysis of the third reason: The power supply voltage is too low
Solution: Increase the voltage
2. The temperature of the equipment is too high when using it
Analysis of one of the reasons: poor heat dissipation
Solution: Check whether the fan is running normally and clean the dust accumulated on the fan.
Analysis of the second reason: the equipment has been in high light intensity illumination mode for a long time
Solution: Generally, if long-term high-intensity exposure is required, it is recommended to choose a water-cooled UVLED light curing machine, which has better heat dissipation effect.
