Description

Technical Field

[0001] The present invention relates to the technical field of photocuring, and in particular to an anti-oxidation and anti-agglomeration photocuring device and method. Background Art

[0002] UV curing in an oxygen-free environment is an important step in the 3D printing process. After the dispensing printing is completed, the glue is prone to collapse or deform over time, resulting in the printed product being defective in function or appearance. In addition, some glues will experience oxygen inhibition when UV-curing in an aerobic environment.

[0003] In order to ensure that the glue morphology is fixed after printing is completed and to avoid oxygen inhibition during the curing process, the semi-open structure is currently mainly used on the market. Inert gas is filled into the curing position to achieve a local oxygen-free environment. This type of mechanism has at least the following technical defects: (1) It is only suitable for UV curing requirements in a small range of oxygen-free environment. For large-size products, it is impossible to ensure an oxygen-free environment during the overall curing process and avoid the occurrence of oxygen inhibition; (2) The semi-open structure requires the inert gas to be kept flowing throughout the curing process, which not only wastes resources, but also causes overflow to the external environment, posing a personal safety hazard.

[0004] The Chinese patent document discloses "a UVLED oxygen-free curing tunnel furnace", and its publication number is CN220514663U. The patent includes a shell, a conveying device, and an oxygen-free curing device. The shell is wrapped around 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 chamber. The oxygen-free curing device includes a matching UV curing light source; the entrance and exit of the oxygen-free curing chamber are both provided with wind knives. The patent uses a conveyor belt for transportation, and uses a wind knife to achieve a device to block external oxygen. A multi-level isolation of a small inert gas injection box and a large inert gas injection box is used in sequence near the curing position to create an oxygen-free atmosphere. However, the UVLED oxygen-free curing tunnel furnace of the patent still adopts a semi-open structure. The principle of using the wind knife still requires the inert gas to be kept in the entire curing process, which not only causes a waste of resources, but also overflows to the external environment, causing personal safety hazards. Summary of the invention

[0005] In view of the shortcomings of the prior art mentioned above, the object of the present invention is to provide an antioxidant and anti-agglomeration photocuring device and method, which is used to solve the problem that the existing semi-open photocuring device maintains the introduction of inert gas during the entire curing process, which not only causes waste of resources, but also overflows into the external environment, posing a personal safety hazard.
