Device and method for atomization cleaning of 3D printing photosensitive resin

Abstract

The invention belongs to the field of resin product treatment, and concretely relates to a device and a method for atomization cleaning of 3D printing photosensitive resin. The device comprises a cleaning tank, alcohol containers, a high gas system and a waste liquid collector. A filter screen baffle plate is arranged in the cleaning tank to prevent the above product from directly immersing in alcohol; the cleaning tank adopts a glass cover plate, so the cleaning tank is visible; the front side of the cleaning tank is provided with a glove operating opening, so the cleaning tank is convenient to clean; three alcohol containers are arranged above the cleaning tank, and are respectively used for containing cleaning liquids recovered at different recovery times, the rear side of the cleaning tank is provided with a high pressure gas pipeline to realize alcohol atomization, and valve switches are arranged below the alcohol containers and on pipelines to control the flow; and a valve arranged below the cleaning tank, and a waste liquid collecting container is arranged below the valve. Grading multi-time recovery, one-time recovery and new alcohol cleaning are adopted, so the cost is greatly reduced, the cleaning flow of the 3D printing photosensitive resin is standardized, the flow and the pressure are controllable, and rapid cleaning of the surface of the product is realized.

Description

technical field [0001] The invention belongs to the field of resin product processing, and specifically relates to an equipment and method for gas atomization cleaning of 3D printing photosensitive resin. Background technique [0002] 3D printing technology is a technology based on the principle of discrete accumulation, integrated computer graphics processing, digital information and control, electromechanical control technology and material technology, and adopts the method of accumulating materials layer by layer to realize the technology of rapid free forming of parts. With the development of technology, stereolithography photosensitive resin has been widely used in industries such as auxiliary design, structural assembly and functional verification, and rapid casting. [0003] The photosensitive resin material has a high viscosity, and the liquid photosensitive resin adhered to the surface of the product after printing is difficult to clean. At present, the product is s...

AI Technical Summary

Problems solved by technology

[0003] The photosensitive resin material has a high viscosity, and the liquid photosensitive resin adhered to the surface of the product after printing is difficult to clean. At present, the product is soaked in a container filled with alcohol or isobutanol, and the product is shaken continuously. The cleaning method causes the solvent to be exposed for a long time, volatilizes and wastes alcohol and other cleaning solvents and is harmful to the human body; and the cleaning time is not easy to control. If the time is too long, the cured product will be dissolved and the product is unqualified. If the time is too short, the photosensitive surface adhered Resin cannot be cleaned

In the state of mass production, this cleaning method cannot meet the needs of industrial production
