The device for curing is called curing furnace, which is mainly used for heat treatment and curing process of various materials. The furnace body for curing by ultraviolet is also called UV curing furnace.

[0003] However, when the existing UV curing furnace for semiconductor packaging silver glue curing is used, the airflow entering the furnace is easy to carry dust due to the need to maintain good ventilation in the curing furnace. When the ultraviolet lamp in the furnace is on, the dust entering the furnace is easy to be adsorbed on the surface of the ultraviolet lamp under the action of current. If the adsorbed dust is not treated in time, it will interfere with the irradiation effect of the ultraviolet lamp when the dust on the surface of the ultraviolet lamp becomes thicker, affecting the curing effect. In addition, since the ultraviolet lamp in the UV curing furnace is a high-consumption item, it needs to be checked regularly. Since the ultraviolet lamp is usually installed at the center of the furnace and the irradiation surface is usually perpendicular to the conveyor belt, the specific on-off condition of the internal lamp beads cannot be seen clearly when the ultraviolet lamp is checked. The ultraviolet lamp needs to be disassembled and then checked by power-on, which makes the maintenance process of the ultraviolet lamp in the curing furnace more troublesome and time-consuming.
