る。According to the ultraviolet curing irradiation device having the above structure, when the ultraviolet curing light source inside the irradiation device is turned on, an ascending air current is generated due to the rise in temperature. Further, according to the above apparatus, the clean air becomes weaker and inhomogeneous as it goes inward. Therefore, the fine dust contained in the ascending airflow has a lower discharge rate to the outside as it goes inward, and the fine dust adheres to the work at a higher rate, which lowers the performance of the liquid crystal panel and also reduces the defective rate. Will increase.

出する。The present invention has the following constitution in order to solve the above problems. That is, the present invention relates to an apparatus in which a light source chamber for accommodating a light source for ultraviolet ray curing is provided above a conveyor, and a film on the surface of a work placed on the upper surface of the conveyor is ultraviolet ray cured by a light source for ultraviolet ray curing. Further, an air purifying filter chamber is provided above the light source chamber, and clean air is fed from the air purifying filter chamber through the light source chamber and onto the conveyor. Then, the dust soared by the ascending air current is discharged to the outside from below the conveyor.

率よく得ることが可能となる。According to the ultraviolet curing irradiation device having the above structure,
The temperature of the irradiation chamber rises when the UV curing light source is turned on, but since the air that has passed through the air purification filter passes through the light source chamber and is sent onto the conveyor and discharged from below the conveyor, it rises. Dust will not rise due to the air flow. Therefore, dust does not adhere to the liquid crystal panel, and a uniform and high-performance liquid crystal panel can be efficiently obtained.
