Description

Technical Field

[0001] The utility model relates to the technical field of UV curing, in particular to a small-sized nitrogen-protected UV curing device. Background Art

[0002] A nitrogen-protected UV curing system refers to a system established in a relatively airtight space filled with an inert gas (mainly nitrogen), thereby reducing the influence of oxygen and water vapor in the air on the UV curing reaction.

[0003] For example, the Chinese utility model patent with the publication number CN216033191 U discloses a drawer-type nitrogen-protected UV curing machine, which includes a drawer-type carrier component, a nitrogen cavity component, a UV curing component, a UV lamp height adjustment component, and an electrical control component. The drawer-type carrier component is arranged inside the nitrogen cavity component, and a sealed cavity is formed by the drawer-type carrier component and the nitrogen cavity component. Moreover, the top of the nitrogen cavity component is hermetically connected and designed through quartz glass, which greatly reduces the inner cavity space of the nitrogen cavity component. However, the problems it has are: high production cost and large occupied volume, which are not conducive to transportation and carrying.

[0004] Another example is the Chinese utility model patent with the publication number CN209438938U, which discloses a nitrogen-protected UV curing device. The above-mentioned device includes an upper plate, a lower plate, two side plates, and a nitrogen inlet. The upper plate, the lower plate, and the two side plates form a containing cavity. The upper plate is provided with a UV curing glass. The front and back sides of the containing cavity are provided with entrances and exits for products to be UV-cured to enter and exit. The distance between the upper plate and the lower plate is 4-6 mm. The problems it has are that during the curing process, the entrances and exits are not sealed, and it is necessary to continuously transport flowing nitrogen to protect the products from being affected, but dust or other gases still cannot be completely isolated, the use cost of nitrogen is high, and the products are easily affected by the external environment. Summary of the Utility Model

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a small-sized UV curing device with low production cost, good sealing performance and easy to carry.

[0006] The technical solution adopted by the utility model to solve the problem is: a small-sized nitrogen-protected UV curing device, including

[0007] a box body, the inside of the box body is hollow and the front side is open, a sealing cover is detachably connected to the opening, and an air inlet joint and an exhaust joint are arranged on the sealing cover.

[0008] After putting the optical film product into the box body, seal the sealing cover and the box body, open the air inlet joint to fill nitrogen, and when the nitrogen is full, the device can be put into a UV exposure machine for curing. It has a small structure, low production cost, and is easy to carry and transport.

[0009] As a further improvement of the above technical solution, the box body includes a main body with an open top and a quartz glass cover plate detachably connected to the top of the main body. The quartz glass cover plate is provided with a frosted area, and the frosted area is in contact with the sealing cover. This increases the friction between the box body and the sealing cover and prevents the sealing cover from falling off and causing nitrogen leakage.

[0010] As a further improvement of the above technical solution, a drawer part is provided at the rear side of the sealing cover, and the drawer part is inserted into the box body. Setting up a drawer enables the product to be placed more smoothly.

[0011] As a further improvement of the above technical solution, the edge of the sealing cover extends backward to form a flanging, and the flanging is in contact with the frosted area. This increases the sealing performance and structural stability between the box body and the sealing cover.

[0012] As a further improvement of the above technical solution, the height of the box body is 2 - 5 cm. The box body includes multiple plates, which are detachably connected to each other, and the material of the plates is organic plastic. With a relatively low height and small volume, it is convenient to place the product and also reduces the consumption of nitrogen. The box body is assembled by splicing organic plastics, which is heat-resistant, insulating, waterproof and moisture-proof, and is also convenient for disassembly and cleaning.

[0013] As a further improvement of the above technical solution, the air inlet joint is a three-way joint, a switch is provided on the air inlet joint, and one end of the air inlet joint is communicated with a nitrogen storage device. After the nitrogen fills the box and the exhaust joint is closed, the air inlet joint (three-way joint) can simultaneously inflate and exhaust, preventing air impurities and the like from entering the box body through other gaps and ensuring that the box body is completely filled with nitrogen.

[0014] As a further improvement of the above technical solution, the exhaust joint is a three-way joint. The air inlet joint and the exhaust joint have the same function and can be exchanged and used in different situations, making it more convenient to use.

[0015] Preferably, the box body and the sealing cover are hermetically bonded with tape. This strengthens the structural sealing performance.

[0016] Preferably, the material of the plate is PMMA or PC plastic.

[0017] The beneficial effects of the present utility model are as follows: By combining a small and portable box body with a sealing cover, the box body is provided with a quartz glass cover plate, the sealing cover is provided with nitrogen inlets and outlets, and a frosted area is provided between the box body and the sealing cover to ensure the sealing performance, thus forming a small UV curing device, effectively reducing the production cost of the UV curing device, reducing the occupied volume, and being convenient for transportation and carrying.
