Description

Ultraviolet irradiation device

The present invention relates to an ultraviolet irradiation device.

In the prior art, an ultraviolet curable resin is often used as a spotting agent. It is used by applying an ultraviolet curing resin between two workpieces, and then irradiating the ultraviolet curing resin with ultraviolet light in an ultraviolet irradiation device to cure the ultraviolet curing resin to bond the two workpieces. For different workpieces, the position of the UV-curable resin is different, so the position where ultraviolet light irradiation is required is also different. However, the existing ultraviolet irradiation device usually fixes the ultraviolet light source at a certain position, and it is difficult to adjust the position of the ultraviolet light source according to the position of the ultraviolet curing resin coated on the workpiece, thereby causing uneven curing of the ultraviolet curing resin.
