Description

TECHNICAL FIELD

[0001] The utility model relates to the field of photocuring technology, in particular to an oxygen-resistant and polymerization-resistant photocuring device. BACKGROUND

[0002] UV curing under oxygen-free environment is an important link in the 3D printing process. After point gluing printing is completed, the glue is prone to collapse or deformation over time, resulting in a defective product in terms of function or appearance. In addition, some glues will undergo oxygen inhibition when UV curing in an oxygen-containing environment.

[0003] To ensure that the glue morphology is fixed after printing is completed, and to avoid the occurrence of oxygen inhibition during the curing process, the market currently mainly adopts a semi-open structure, which fills inert gas into the curing position to achieve a local oxygen-free environment. However, this type of mechanism has at least the following technical defects: (1) It is only suitable for UV curing requirements in a small oxygen-free environment, and cannot ensure an oxygen-free environment and avoid oxygen inhibition for large-size products during the overall curing process; (2) The semi-open structure requires the continuous introduction of inert gas during the entire curing process, which not only wastes resources but also causes leakage into the external environment, posing a safety hazard to people.

[0004] A UVLED oxygen-free curing tunnel furnace is disclosed in Chinese patent document CN220514663A. This patent includes a shell, a conveying device, and an oxygen-free curing device. The shell encloses the conveying device and the oxygen-free curing device. The shell and the oxygen-free curing device cooperate with the upper conveying surface of the conveying device to form an oxygen-free curing cavity. The oxygen-free curing device includes a matching UV curing light source. Air knives are provided at the entrances and exits of the oxygen-free curing cavity. This patent uses a conveyor belt for transportation and air knives to block external oxygen. It uses multiple layers of small and large inert gas injection boxes near the curing position to achieve an oxygen-free environment. However, the UVLED oxygen-free curing tunnel furnace still uses a semi-open structure, which requires the continuous introduction of inert gas during the entire curing process. This not only wastes resources but also causes leakage into the external environment, posing a safety hazard to people. SUMMARY

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present utility model is to provide an oxygen-resistant and polymerization-resistant photocuring device to solve the problem of resource waste and safety hazards caused by leakage into the external environment due to the continuous introduction of inert gas during the entire curing process of the existing semi-open photocuring device.
