Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, specifically relating to a cleaning device for automatically changing cleaning fluid and a photopolymerization 3D printer. Background Technology

[0002] After a 3D model is printed using a photopolymer 3D printer, it needs to be cleaned to remove excess material from its surface. Current photopolymer 3D printers typically use alcohol or ultrasonic cleaning fluid as cleaning agents. Alcohol is an effective organic solvent that can dissolve resin, but it needs to be replaced regularly and its concentration adjusted to maintain cleaning effectiveness. Ultrasonic cleaning fluid utilizes cavitation to efficiently clean the surface and fine structures of the parts, but it does not dissolve the printing material, resulting in less effective cleaning.

[0003] The existing cleaning devices used in photopolymer 3D printers still require manual assistance in the cleaning process of finished parts. For example, when using alcohol or other alcohol-based dissolution methods, the alcohol cleaning agent needs to be manually replaced periodically; when using ultrasonic cleaning methods, excess material that is difficult to remove with ultrasonic cleaning fluid needs to be manually cleaned with a brush. The cleaning devices used in existing photopolymer 3D printers have the drawbacks of being cumbersome to operate and requiring manual assistance. Utility Model Content

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0039] Example 1

[0040] like Figure 1 and Figure 2 The present invention provides a specific embodiment of an automatic cleaning fluid replacement cleaning device 1, which includes: a cleaning box 11, an inlet hole 12 and an outlet hole 13 at the bottom of the cleaning box 11, a cleaning agent storage tank 14, a waste liquid collection tank 15, and an ultrasonic vibrator installed on the cleaning box 11. The outlet of the cleaning agent storage tank 14 is connected to the inlet hole 12 via an inlet pump 17, and the inlet of the waste liquid collection tank 15 is connected to the outlet hole 13 via a pipe. The cleaning agent in the cleaning agent storage tank 14 is alcohol. Control valves for controlling the on / off of the pipes are provided on the pipes between the outlet of the cleaning agent storage tank 14 and the inlet pump 17, and on the pipes between the inlet of the waste liquid collection tank 15 and the outlet hole 13.

[0041] The present invention relates to a cleaning device 1 for cleaning printed 3D finished parts. It combines an alcohol cleaning agent that can dissolve resin materials with an ultrasonic vibrator to ensure a better cleaning effect on 3D finished parts and solves the problem of incomplete cleaning of finished parts by ultrasonic cleaning in the prior art.

[0042] Meanwhile, an inlet hole 12 and an outlet hole 13 are provided at the bottom of the cleaning box 11. The inlet hole 12 is connected to the cleaning agent storage tank 14 containing alcohol cleaning agent through a pipeline, and the outlet hole 13 is connected to the waste liquid collection tank 15 collecting waste liquid after cleaning through a pipeline. The waste liquid in the cleaning box 11 is transported to the waste liquid collection tank 15 by the gravity of the waste liquid itself or by the liquid collection pump 16. Then, the cleaning agent in the cleaning agent storage tank 14 is transported to the cleaning box 11 by the inlet pump 17, thereby realizing the automatic replacement of alcohol cleaning agent in the cleaning box 11. The entire cleaning process of the finished parts and the replacement of cleaning agent does not require manual assistance and can be completed automatically, saving manpower and solving the problem that in the existing technology, when using alcohol cleaning, the waste liquid after long-term cleaning needs to be manually replaced periodically or a certain number of times.

[0043] It should be understood that in this embodiment, the outlet hole 13 at the bottom of the cleaning box 11 is connected to the waste liquid collection tank 15 through a pipeline. When the vertical height of the outlet hole 13 is higher than the inlet of the waste liquid collection tank 15, the waste liquid in the cleaning box 11 can be discharged into the waste liquid collection tank 15 by its own gravity. In order to ensure that the waste liquid in the cleaning box 11 is completely discharged or to avoid placing the waste liquid collection tank 15 at a position higher than the outlet hole 13 of the cleaning box 11, this embodiment provides a liquid collection pump 16 on the pipeline between the inlet and outlet hole 13 of the waste liquid collection tank 15 to ensure that the waste liquid in the cleaning box 11 is recycled into the waste liquid collection tank 15.

[0044] like Figure 1 As shown, it should be further explained that the cleaning device 1 in this embodiment also includes a control module 18 and a power module 19. The control module 18 is used to control the start-up of the ultrasonic vibrator, the inlet pump 17, and the outlet pump 16, as well as to control the opening and closing of the control valve. The power module 19 is used to provide electrical energy to the control module 18, the control valve, the ultrasonic vibrator, the inlet pump 17, and the outlet pump 16. Those skilled in the art can make applicability adjustments to the model and control commands of the control module 18 according to actual needs. The specific contents of the control module 18 will not be described in detail here.

[0045] Example 2

[0046] like Figures 3-5 As shown, the second embodiment of this photopolymer printer using the above-mentioned automatic cleaning fluid replacement cleaning device 1 includes a frame 2, a rotating platform 3 rotatably mounted on the frame 2, a printing device 4, and at least one material box 5 fixedly mounted on the rotating platform 3. During installation, the cleaning box 11 in the cleaning device 1 is fixedly mounted on the rotating platform 3 and rotates with the rotating platform 3. The cleaning agent storage tank 14 and the waste liquid collection tank 15 are both set on the frame 2, and the cleaning agent storage tank 14 and the waste liquid collection tank 15 are both placed below the rotating platform 3.

[0047] like Figure 5 As shown, the rotating platform 3 in this embodiment includes a rotary motor mounted on the frame 2, a rotating disk 31 coaxially arranged with the output shaft of the rotary motor, and several clearance slots 32 formed on the rotating disk 31. The clearance slots 32 are arranged in a circumferential array on the rotating disk 31. During installation, the cleaning box 11 is installed on any of the clearance slots 32, ensuring that the liquid inlet 12 and the liquid outlet 13 are both located in the corresponding clearance slots 32. This prevents the pipe from being unable to connect with the liquid inlet 12 and / or the liquid outlet 13, ensuring that the liquid path between the liquid inlet 12 and the cleaning agent storage tank 14, and between the liquid outlet 13 and the waste liquid collection tank 15 is unobstructed, and ensuring the smooth delivery of liquid in the pipe.

[0048] In this second embodiment, the remaining clearance groove 32, excluding the cleaning box 11, is used to install the material box 5 and a drying mechanism. The material box 5 is recessed and mounted on the rotary disk 31, facilitating material acquisition by the printing device 4. The rotary disk 31 in this second embodiment has several radial through holes 33 for lines or pipes to pass through. The radial through holes 33 communicate with the clearance groove 32. See details... Figure 5 The radial through hole 33 ensures that the lines and pipes used in the cleaning device 1 will not be damaged due to the rotation of the rotating disk 31.

[0049] In a preferred embodiment, the printing device 4 includes a lifting mechanism 41 mounted on the frame 2 and a printing platform 42 mounted on the output end of the lifting mechanism 41. In this second embodiment, the lifting mechanism 41 drives the printing platform 42 to move in the vertical direction. The specific structure of the lifting mechanism 41 and its connection relationship with the frame 2 are all based on readily available technical solutions in the prior art, and will not be described in detail here.

[0050] In this second embodiment, the printing surface of the printing platform 42 is one of a smooth surface, an anodized surface, or an 80-mesh frosted surface. In practical applications, we have found that the smoothness of the printing surface of the printing platform 42 has a significant impact on the ease of handling finished parts printed from different materials. Specifically, for a standard smooth surface, it is relatively versatile for conventional rigid materials, with moderate adhesion and demolding ease. For anodized surfaces, it has relatively weak adhesion for flexible materials with strong adhesion, but easy demolding. For 80-mesh frosted surfaces, it has relatively strong adhesion for powder materials with weak adhesion. Therefore, in this second embodiment, the printing surface of the printing platform 42 is one of a smooth surface, anodized surface, or 80-mesh frosted surface, with adjustments made according to the different materials used.

[0051] In actual use of the photopolymer 3D printer in this embodiment 2, the alcohol cleaning agent in the cleaning box 11 is replaced at regular intervals or after a certain number of cleaning cycles. Specifically, the selection and adjustment can be made according to the needs of the site or the different 3D printing materials.

[0052] The photopolymer 3D printer in this embodiment uses the cleaning device 1 that can automatically replace the cleaning fluid. Its rotating platform 3 has a targeted structural design for the cleaning device 1. This ensures that the cleaning device 1 can effectively clean the printed 3D finished parts and automatically replace the cleaning fluid in the cleaning box, resulting in good cleaning effect and high efficiency. At the same time, the connection lines and pipelines between the components are reasonably planned, and there will be no damage or interference.

[0053] It should be understood that the specific embodiments one and two described above are only for explaining this utility model and are not intended to limit this utility model. Obvious changes or modifications derived from the spirit of this utility model are still within the protection scope of this utility model.
