Problems solved by technology
[0004] The function of the scraping system is to scrape the surface of the resin molding liquid to ensure the smoothness of each side. However, because the photopolymerization of photosensitive resin has the characteristics of oxygen inhibition, the current SLA industrial structure cannot avoid the contact of the molding surface with oxygen. Polymerization leads to incomplete photopolymerization, resulting in adverse effects on the properties of molded products, resulting in a large number of waste and defective products

Embodiment
[0018] Such as figure 2 It is the use structure diagram of the present invention, the SLA machine starts to work, the laser 1 emits laser light to perform linear scanning, the host computer controls the motor device 3 through the program, and the motor device 3 drives the transmission system to keep the transparent scraper 4 and the linear scanning laser in synchronous motion at any time. The motor device 3 drives the screw rod 21 to move, and the screw rod 21 moves the transparent scraper 4 along the guide rail 22 through the slider 23 to ensure that the laser always passes through the transparent scraper 4 before touching the photosensitive resin, so that the laser sweeps on the transparent scraper 4 On the top, half of the transparent scraper is submerged under the resin, and when the laser passes through the transparent scraper 4, the resin under the scraper can be cured under the condition of isolating oxygen. Under the premise of realizing the original scraping function...

The invention relates to an oxygen-obstructing light-permeating liquid scraping system which comprises a laser and further comprises a main machine, a transmission system, a motor device and a transparent scraper. The main machine is connected with the motor device, the motor device provides power and is connected with the transmission system, the transmission system drives the transparent scraper to move, and lasers permeate the transparent scraper all the time. The motor device is used for driving the transmission system, so that the transparent scraper and linear scanning lasers are kept moving synchronously at any time, the lasers scan the transparent scraper, resin below the scraper can be cured under the oxygen obstructing condition when the lasers permeate the transparent scraper, and the liquid scraping system with the oxygen obstructing function is acquired. On the premise that the original scraping function of the scraping system is achieved, the photosensitive resin is cured in an oxygen-obstructing manner, and the performance of a molded product is improved.
Description
technical field [0001] The invention relates to the field of 3D printing, in particular to an oxygen-blocking and light-transmitting liquid scraping system. Background technique [0002] The current liquid leveling system is widely used in industrial-grade SLA technology, which is based on the principle of photopolymerization of liquid photosensitive resin. This liquid material can rapidly undergo photopolymerization under the irradiation of ultraviolet light of a certain wavelength and intensity, and the molecular weight increases sharply, and the material changes from liquid to solid. [0003] The working principle of 3D printing application SLA technology is that the liquid tank is filled with liquid photocurable resin, and the laser beam can scan on the liquid surface. The scanning trajectory and the presence or absence of light are controlled by the computer. Where the light spot hits, the liquid Just solidify. At the beginning of molding, the working platform is unde...
