Abstract

Disclosed is an ultraviolet irradiation device for package of a light-emitting diode. The ultraviolet irradiation device includes a sealed shell. A light-emitting diode to be packaged is arranged in the shell, and a UV mask that is movable in the shell is arranged below the light-emitting diode. The ultraviolet irradiation device further includes a UV lamp arranged below the UV mask. The ultraviolet irradiation device further includes a sealed chamber which is in communication with the shell. The chamber is arranged at a side of the shell. A first rolling unit that is configured to deliver the light-emitting diode is arranged in the chamber, and a first gate and a second gate are respectively arranged at two ends of the chamber. The chamber is further in communication with an air exhaust unit and a first gas source respectively. The structure of the ultraviolet irradiation device is simple. When a replacement of the UV mask is performed, a rapid replacement thereof can be achieved, i.e., much time for replacing the UV mask can be saved, which is beneficial for improving productivity.

Claims
