[0002] In 3D printing technology, the more common one is the light-curing rapid prototyping technology, which uses a liquid photosensitive resin to undergo a polymerization reaction under light irradiation. The light source irradiates according to the cross-sectional shape of the entity to be cured, so that the liquid photosensitive resin is cured layer by layer and then accumulatively stacked to finally form a cured entity.

[0003] In the prior art, when the model is cured, uncured liquid resin is likely to adhere to the surface, so it needs to be cleaned with a special cleaning agent. During the cleaning process of the model by some cleaning equipment, the cleaning agent cannot be more evenly applied to the surface of the model, so there are certain limitations. At the same time, after being used for multiple cleanings, the cleaning agent in some cleaning equipment will lose its original cleaning ability due to containing more uncured resin, affecting the cleaning effect, so this needs to be solved.

[0034] Embodiment 1, as Figures 1-4 shown, the present utility model provides a light-curing 3D printing cleaning device, including: a cleaning tank 1, and a top cover 103, which is movably installed on the surface of the cleaning tank 1; further including: a sealing ring 1031, which is arranged on the outer surface of the top cover 103, and the sealing ring 1031 is movably embedded in the inner wall of the cleaning tank 1; a slide rail 101, which is opened on the surface of the cleaning tank 1, and a return frame 102 is slidably embedded in the slide rail 101. A filter plate 1021 is arranged inside the return frame 102, and a plurality of filter holes 1022 are opened on the surface of the filter plate 1021; an inner cavity 104, which is opened inside the cleaning tank 1 near the center, and a plurality of spray heads 1041 are arranged on the inner walls of the opposite sides of the cleaning tank 1, and the plurality of spray heads 1041 communicate with the inner cavity 104.

[0035] In this embodiment, when the bidirectional lead screw 2031 inside the U-shaped frame 203 is rotated, the clamping plates 2033 at both ends move relatively on the surface of the guide rod 2032 to perform the limiting work on the clamping plates 2033. The clamping plates 2033 are used to position the model or the material to be cleaned. When the drive motor 201 on the surface of the mounting frame 2 works, it drives the U-shaped frame 203 to rotate, and at the same time, the limiting piece 202 on the output end surface performs the limiting work, so that the model or the material rotates, which is convenient for the cleaning agent to be evenly sprayed on the surface and better for cleaning. Cooperating with the sealing ring 1031 movably connected inside the cleaning tank 1, it prevents the cleaning agent from volatilizing and at the same time protects the operator from exposure to harmful chemicals.

[0036] Embodiment 2, a water pump 105 is provided on one side surface of the cleaning tank 1. A first connecting pipe 1051 is provided on one side surface of the water pump 105. One end of the first connecting pipe 1051 communicates with the inside of the inner cavity 104. A second connecting pipe 1052 is provided on one side surface of the water pump 105. One end of the second connecting pipe 1052 is connected to the inside of the cleaning tank 1. An installation frame 2 is fixedly installed on the side surface of the cleaning tank 1 away from the water pump 105. A driving motor 201 is fixedly installed on one side surface of the installation frame 2. A limiting piece 202 is provided on the output end surface of the driving motor 201. The limiting piece 202 is slidably connected to the surface of the cleaning tank 1. A U-shaped frame 203 is fixedly installed on the output end surface of the driving motor 201. A bidirectional lead screw 2031 is movably embedded in one side inner wall of the U-shaped frame 203. Clamping plates 2033 are sleeved on the surface of the bidirectional lead screw 2031 at opposite positions. One end surface of each of the two clamping plates 2033 is movably embedded with a guide rod 2032. The guide rod 2032 is fixedly installed on the inner wall of the U-shaped frame 203.

[0037] In this embodiment, when the water pump 105 works, it is connected to the inside of the cleaning tank 1 through the second connecting pipe 1052, and the cleaning agent inside is transmitted to the inside of the inner cavity 104 through the first connecting pipe 1051 and sprayed onto the surface of the model or material through the nozzle 1041. At the same time, the slide rail 101 mounts the return frame 102 on the surface, so that the resin particles and impurities in the cleaning agent after cleaning are filtered through the filter holes 1022, and part of the resin particles and impurities fall on the surface of the filter plate 1021. Then, by removing the return frame 102, the resin particles and impurities inside are cleaned, thereby maintaining the cleanliness of the cleaning agent and prolonging its service life.

[0038] Working principle: During use, when rotating the bidirectional lead screw 2031 inside the U-shaped frame 203, it drives the clamping plates 2033 at both ends to move relatively on the surface of the guide rod 2032, performs the limiting work on the clamping plates 2033, and positions the model or the material to be cleaned through the clamping plates 2033. When the drive motor 201 on the surface of the mounting frame 2 works, it drives the U-shaped frame 203 to rotate, and at the same time, the limiting piece 202 on the output end surface performs the limiting work, causing the model or the material to rotate, facilitating the uniform spraying of the cleaning agent on the surface and better cleaning. The sealing ring 1031 is movably connected inside the cleaning tank 1 to prevent the volatilization of the cleaning agent and at the same time protect the operator from exposure to harmful chemicals. In addition, when the water pump 105 works, it is connected to the inside of the cleaning tank 1 through the connecting pipe two 1052, and transfers the internal cleaning agent to the inside of the inner cavity 104 through the connecting pipe one 1051, and sprays it onto the surface of the model or the material through the nozzle 1041. At the same time, the slide rail 101 mounts the return frame 102 on the surface, so that the resin particles and impurities in the cleaning agent after cleaning are filtered through the filter holes 1022, and part of the resin particles and impurities fall on the surface of the filter plate 1021, and then the resin particles and impurities inside are cleaned by taking out the return frame 102, thereby maintaining the cleanliness of the cleaning agent and extending its service life.
