Description

Technical Field

[0001] This utility model belongs to the field of curing equipment technology, and specifically relates to an oxygen-free space curing device. Background Technology

[0002] UV adhesives cure in a confined space. When the door is opened, oxygen from the air enters the curing space. In an oxygen-rich environment, the UV adhesive does not cure completely, resulting in incomplete curing and negatively impacting the quality of the UV adhesive curing on the product. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an oxygen-free space curing device, which provides an oxygen-free space for the UV adhesive to be cured, thereby improving the curing quality of the UV adhesive.

[0004] This invention is implemented as follows: An oxygen-free space curing device is provided, comprising an outer chamber and an inner chamber, with the inner chamber located inside the outer chamber. Inlets are provided on the same side of both the outer and inner chambers, and outlets are provided on opposite sides of both chambers. First air knife assemblies are provided at the inlets and outlets of the outer chamber, and second air knife assemblies are provided at the inlets and outlets of the inner chamber. A conveyor roller assembly and a UV lamp are provided within the inner chamber. An air inlet and an air outlet are also provided on the inner chamber. The air inlet is connected to an air inlet pipe, through which oxygen-free gas enters the inner chamber. Gas within the inner chamber is discharged through the air outlet. A substrate coated with UV adhesive to be cured is placed on the conveyor roller assembly and transported from the inlet to the outlet. The UV lamp is positioned on top of the substrate. An exhaust port is also provided on the outer chamber, through which gas within the outer chamber is discharged.

[0005] Furthermore, the second air knife assembly is provided with an upper air knife and a lower air knife, which simultaneously blow and brush the upper and lower sides of the substrate.

[0006] Furthermore, the oxygen-free gas is nitrogen.

[0007] Furthermore, an exhaust pipe is provided at the exhaust port, and a one-way valve is provided on the exhaust pipe.

[0008] Compared with existing technologies, the oxygen-free space curing device of this invention includes an outer chamber and an inner chamber. A first air knife assembly is installed at the inlet and outlet of the outer chamber, and a second air knife assembly is installed at the inlet and outlet of the inner chamber. A conveyor roller assembly and a UV lamp are installed within the inner chamber. An air inlet and an air outlet are also provided on the inner chamber. A substrate coated with UV adhesive to be cured is placed on the conveyor roller assembly and transported from the inlet to the outlet. The UV lamp is positioned on top of the substrate. An exhaust port is also provided on the outer chamber, through which gas inside the outer chamber is discharged. This invention uses air knife assemblies at the inlet and outlet to form an air curtain, protecting the inlet and outlet from outside air entering the inner chamber and creating an oxygen-free space. This facilitates the curing of the UV adhesive on the product within the inner chamber and improves the curing quality of the UV adhesive. Attached Figure Description
