UV light curing machine The luminous principle is through UVLED The chip emits pure ultraviolet light, thereby UV glue , UV ink and other UV coating coatings can be irradiated to achieve fast and good curing effect. UV light curing It is a dryer with a high degree of environmental protection on the current market. solidify way, it can instantly make UVLED equipment It lights up and emits ultraviolet light with a main peak of about 360nm (there are also other wavelengths) to complete curing. generally the whole process It only takes a few seconds and does not produce environmentally harmful substances like mercury lamps. What are the common faults of UV curing machines, what are the causes and what are the solutions. Yongcheng Optoelectronics has compiled some for your reference.

　Possible faults, causes and solutions

 1. UVLED lamp beads do not light up or self-extinguish

 One of the reasons for analysis: UVLED lamp beads will produce a certain degree of attenuation as they are used longer.

　Solution: You can replace the lamp beads appropriately and analyze

 Reason 2: Not enough air cooling

 Solution: Clear the air duct and clean the fan wheel debris

 Analysis of the third reason: The power supply voltage is too low

 Solution: Increase the voltage

 3. 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.
