Description
Technical Field
[0001] This application mainly relates to the field of 3D printing technology, and in particular to a spin-drying and cleaning integrated device. Background Technology
[0002] With the widespread application of digitalization, photopolymer 3D printing is becoming increasingly common. In 3D printing technology, the printing solvent plays a crucial role as a core material. Its core function is as a photosensitive material, selectively curing layer by layer through specific wavelengths of light (such as UV lasers or projection), transforming from a liquid to a solid state to precisely construct a three-dimensional entity. The properties of the printing solvent directly determine the accuracy, mechanical strength, surface quality, and functionality (such as toughness, temperature resistance, and biocompatibility) of the printed model, making it a key fundamental material affecting the performance and applicability of the final product. After 3D printing is complete, residual resin on the model must be cleaned promptly to ensure the safety and durability of the finished product and avoid health hazards and failures in subsequent processes.
[0003] Existing printing model drying and cleaning devices typically operate as two separate machines, with the cleaning device usually using only a single cleaning solution. Using a single cleaning solution cannot guarantee thorough cleaning or ensure no printing agent residue remains on the printed model. Furthermore, current technologies often use oils or alcohol as cleaning solutions, which are not only expensive and potentially hazardous, but also leave a persistent odor on the printed model, negatively impacting the user experience. Additionally, cured printing agents often form a sticky layer or white patches on the printed model, compromising its smoothness and detail. Residual printing agents further hinder complete curing, leading to weakened mechanical strength, brittleness, or deformation of the parts. Moreover, uncleaned printing agents can contaminate the working environment or other items, accelerating the aging of tools and consumables. Utility Model Content

[0032] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this application. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.
[0033] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not specifically singular and may include plural forms. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.
[0034] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0035] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0036] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0037] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

Moreover, this application should be understood not only through the actual terms used, but also through the meaning implied by each term.
[0038] This application refers to Figures 1-11 A spin-drying and cleaning integrated device 10 (hereinafter referred to as "integrated device 10") is proposed. The spin-drying and cleaning integrated device proposed in any embodiment of this application is applicable to the spin-drying and cleaning of the printed model after 3D printing. The following will first refer to... Figures 1-5 Introducing the integrated device 10. Among them, Figure 1 and Figure 2 This diagram shows the internal perspective structure of the integrated device 10 when the spin-drying device cover 21 of the spin-drying device 11 and the cleaning device cover 31 of the cleaning device 12 are open. Figure 3 and Figure 4 This diagram shows the internal perspective structure of the integrated device 10 when the spin-drying device cover 21 of the spin-drying device 11 and the cleaning device cover 31 of the cleaning device 12 are closed. Figure 5 This shows a schematic diagram of the specific structure of the cleaning device 12.
[0039] First refer to Figures 1-4 The integrated device 10 mainly includes a spin-drying device 11 and a cleaning device 12. The specific structure of the spin-drying device 11 will be introduced first. The spin-drying device 11 is suitable for spin-drying printed models (not shown in the figure). When the spin-drying device 11 is in the spin-drying state, it is loaded with a spin-drying drum 22, and the printed model is suitable for being placed inside the spin-drying drum 22 for spin-drying.
[0040] The spin-drying device 12 includes a spin-drying device cover 21, which has a groove 23. When the printed model is placed inside the spin-drying bucket 22 for spin-drying, the spin-drying device cover 21 is closed. At this time, the groove 23 on the spin-drying device cover 21 corresponds one-to-one with the spin-drying bucket 22 in spatial position. In this preferred embodiment, the inner wall of the groove 23 includes a groove sealing ring 24. When the printed model is spin-drying inside the spin-drying bucket 22, the groove sealing ring 24 can seal the joint between the spin-drying bucket 22 and the groove 23, ensuring that the printing liquid remaining on the printed model during the spin-drying process will not be spun out from the joint between the spin-drying bucket 22 and the groove 23, and ensuring that all the printing liquid remaining on the printed model can remain in the spin-drying bucket 22 for subsequent recycling.
[0041] Furthermore, in this preferred embodiment, the spin-drying drum 22 can be a detachable snap-on filter screen, as detailed in the following reference. Figure 2 The filter screen has multiple filter ports 28. When the printed model is spun dry in the spin dryer 22, the residual ink on the printed model will be spun out through the filter ports 28 and finally flow out through the spin dryer outlet 25, which is connected to the dehydration tank (not shown) on the spin dryer 11. The spin dryer 11 includes a recovery cup 26 and a liquid level sensor 27. The recovery cup 26 includes a recovery cup collection pipe (not shown) connected to the spin dryer outlet 25. The printing ink spun out by the printed model during the spin dryer process can flow into the recovery cup 26 through the spin dryer outlet 25. The liquid level sensor 27 is adapted to detect the liquid level of the recovered printing ink in the recovery cup 26.
[0042] In this embodiment, the residual printing ink on the printed model can be further recovered by the recycling cup 26. The collected residual printing ink can be reused for printing other models, which can save costs to a certain extent and achieve environmental protection effects. Furthermore, the integrated device 10 also includes an alarm device, including an alarm indicator light 29. When the liquid level sensor 27 detects that the printing ink level in the recycling cup 26 exceeds a certain threshold, the alarm indicator light 29 will illuminate to issue an alarm, reminding staff to promptly recover the printing ink in the recycling cup 26 and prepare for a new round of ink recovery. For example, the liquid level threshold can be flexibly adjusted according to actual application conditions, and this application does not impose any limitations on this.
[0043] Continue to refer to Figures 1-5 Now, in combination Figures 1-5 The specific structure of the cleaning device 12 in the integrated device 10 is described in detail. After the printed model is spun dry in the spin-drying device 11, it can be placed in the cleaning device 12 for cleaning. In this preferred embodiment, the spin-drying device 11 and the cleaning device 12 each include a filter snap-fit part (not shown in the figure). As described above, in this embodiment, the spin-drying tub 22 in the spin-drying device 11 is a detachable snap-fit filter. When the printed model is spun dry, the detachable snap-fit filter snaps with the filter snap-fit part of the spin-drying device to serve as the spin-drying tub 22. After the printed model is spun dry, the detachable snap-fit filter is removed from the filter snap-fit part of the spin-drying device 11 and snapped with the filter snap-fit part of the cleaning device 12 to serve as the cleaning tub 32.
[0044] With the above design, during the cleaning and spin-drying process of the printed model, the worker only needs to contact the detachable snap-on filter screen, without having to contact the incompletely cured printed parts inside the spin-drying tub 22. This further avoids chemical damage to the worker's skin caused by the printing solution, improving the safety of cleaning and spin-drying. Simultaneously, the dual-use mode of the detachable snap-on filter screen can further save process costs and improve the economic efficiency of the integrated equipment 10. In other embodiments of this application, the spin-drying tub 22 and the cleaning tub 32 may also use different filters; this application does not impose any limitations on this.
[0045] Furthermore, the cleaning device 12 includes multiple cleaning circuits 33 (see reference). Figure 5 The cleaning device 12, in its cleaning state, is equipped with a cleaning tank 32. The printed model is suitable for placement inside the cleaning tank 32 for cleaning. The cleaning tank 32 is connected to multiple cleaning circuits 33, which are adapted to inject cleaning fluid into the cleaning tank 32 and recover the cleaning fluid. At least two of the cleaning circuits use different cleaning fluids. By using different cleaning fluids in at least two of the cleaning circuits, it is possible to further ensure that the printed model undergoes cleaning with at least two different cleaning fluids inside the cleaning device. This ensures that there is no residual printing ink on the printed model, thereby greatly improving the drying and cleaning effect of the printing ink on the printed model and ensuring that the smoothness, detail accuracy, and mechanical strength of the printed model meet the design requirements.
[0046] A clearer reference Figure 5 In this embodiment, the cleaning circuit 33 includes a first cleaning circuit 41, a second cleaning circuit 42, and a third cleaning circuit 43. The first cleaning circuit 41 includes a first cleaning fluid, the second cleaning circuit 42 includes a second cleaning fluid, and the third cleaning circuit 43 includes a third cleaning fluid. In this embodiment, the first and second cleaning fluids are the same, but the third cleaning fluid is different from both the first and second cleaning fluids. For example, the first and second cleaning fluids are low-cost, odorless liquids with high safety factors, while the third cleaning fluid is water. This further ensures the safety of cleaning the printed model and guarantees that the printed model cleaned by the integrated device 10 will not have an unacceptable odor, thus improving both the user experience and the safety of the cleaning process.
[0047] In this preferred embodiment, the first cleaning circuit 41 is adapted to inject and recover the first cleaning fluid into the printed model after spin-drying for pre-cleaning; the second cleaning circuit 42 is adapted to inject and recover the second cleaning fluid into the printed model after pre-cleaning for main cleaning; and the third cleaning circuit 43 is adapted to inject and recover the third cleaning fluid into the printed model after main cleaning for secondary cleaning. These three cleaning processes—pre-cleaning, main cleaning, and secondary cleaning—ensure a thorough cleaning of the printed model, further guaranteeing that no printing ink residue remains on the printed model, thereby significantly improving the cleaning effect of the printing ink on the printed model.
[0048] In this embodiment, each cleaning circuit 33 includes a circuit inlet end 34 and a circuit outlet end 35. The cleaning device 12 includes a cleaning liquid outlet end 36 and a plurality of cleaning liquid inlet ends 37, wherein the plurality of cleaning liquid inlet ends 37 are respectively connected to the plurality of circuit outlet ends 35 of the plurality of cleaning circuits 33, and the cleaning liquid outlet end 36 is connected to the plurality of circuit inlet ends 34 of the plurality of cleaning circuits 33.
[0049] Furthermore, each cleaning circuit 33 includes a booster pump 38, a cleaning fluid storage chamber 39, and a solenoid valve 30. The booster pump 38 is connected to the storage chamber outlet 44 and the circuit outlet 35 of the cleaning fluid storage chamber 39. The booster pump 38 is adapted to pump the cleaning fluid stored in the cleaning fluid storage chamber 39 into the cleaning fluid inlet 37 through the circuit outlet 35. The solenoid valve 30 is connected to the storage chamber inlet 45 and the circuit inlet 34 of the cleaning fluid storage chamber 39. When the cleaning fluid is discharged from the cleaning fluid outlet 36, the solenoid valve 30 is opened to recover the cleaning fluid into the corresponding cleaning fluid storage chamber 39. Through the configuration of the booster pump 38, the cleaning fluid storage chamber 39, and the solenoid valve 30, the injection and recovery operations of the cleaning fluid in the cleaning circuit 33 can be realized, enabling the recycling of the cleaning fluid, further saving costs, and improving the economic efficiency of the integrated equipment 10.
[0050] We will continue to refer to Figure 5 The process of injecting and recovering the cleaning fluid will be described in detail. For example... Figure 5 As shown, taking the first cleaning circuit 41 as an example, the cleaning fluid storage chamber 39 in the first cleaning circuit 41 stores the first cleaning fluid (correspondingly, the cleaning fluid storage chamber 39 in the second cleaning circuit 41 stores the same second cleaning fluid as the first cleaning fluid, and the cleaning fluid storage chamber 39 in the third cleaning circuit 43 stores water). When the cleaning operation begins, the first cleaning fluid in the cleaning fluid storage chamber 39 of the first cleaning circuit 41 flows out of the storage chamber outlet 44 and flows into the booster pump 38 of the first cleaning circuit 41 through the conduit connected to the booster pump 38. The booster pump 38 of the first cleaning circuit 41 pumps the first cleaning fluid into the cleaning tank 32 to perform the first main cleaning of the printed model.
[0051] Furthermore, after the main cleaning of the printed model is completed, the first cleaning fluid in the cleaning tank 32 will flow out through the cleaning fluid outlet 36 to the circuit inlet 34. At this time, since the printed model is undergoing the main cleaning, the solenoid valves 30 on the second cleaning circuit 42 and the third cleaning circuit 43 are in the closed state, while the solenoid valve 30 on the first cleaning circuit 41 is in the open state. The first cleaning fluid flowing out of the cleaning fluid outlet 36 will finally flow through the solenoid valve 30 into the cleaning fluid storage chamber 39 in the first cleaning circuit 41 connected to the solenoid valve 30, and then the second main cleaning will be performed.
[0052] In this preferred embodiment, a circulation pump 46 and a level sensor 47 are also provided between the cleaning fluid outlet 36 and the circuit inlet 34. Taking the main cleaning as an example, during the main cleaning, after the first cleaning fluid flows out of the cleaning fluid outlet 36, it first flows into the circulation pump 46. The circulation pump 46 can pump the recovered first cleaning fluid into the cleaning fluid storage chamber 39, while the level sensor 47 is suitable for detecting the level of the cleaning fluid inside the cleaning tank 32 to ensure that the cleaning fluid does not overflow from the cleaning tank 32.
[0053] For example, the circulation pump 46 is at least partially transparent. The operator can observe the turbidity of the first cleaning fluid after it flows out of the cleaning fluid outlet 36 through the circulation pump 46 to determine whether the first cleaning fluid needs to be replaced. If the turbidity of the first cleaning fluid is low, the circulation pump 46 can pump the recovered first cleaning fluid into the cleaning fluid storage chamber 39. If the turbidity of the first cleaning fluid is high, the operator can replace the first cleaning fluid as needed, thereby ensuring that the printed model can be cleaned more thoroughly.
[0054] In this embodiment, the second main cleaning and the third secondary cleaning processes can refer to the main cleaning process, and will not be elaborated further here. Furthermore, in this embodiment, the first cleaning circuit 41, the second cleaning circuit 42, and the third cleaning circuit 43 are independent cleaning circuits that are not connected to each other. In other embodiments of this application, cleaning circuits 33 with the same cleaning solution (e.g., the first cleaning circuit 41 and the second cleaning circuit 42 in this embodiment) can be connected. That is, when the cleaning solution in a certain cleaning circuit is insufficient or has high turbidity, the cleaning solution from a cleaning circuit with the same cleaning solution as that cleaning circuit can be pumped into the cleaning tank 32 for cleaning, thereby further saving the amount of cleaning solution used and reducing process costs.
[0055] On the other hand, the cleaning device 12 also includes a cleaning device cover 31, as shown in the figure. Figure 3 and Figure 4 When the cleaning device 12 is operating, the cover 31 of the cleaning device is positioned above the cleaning tub 32. Further reference... Figure 1 and Figure 2An ultrasonic cleaning device 48 is provided on the cover 31 of the cleaning device. The ultrasonic cleaning device 48 is adapted to extend into the cleaning tank 32 and contact the cleaning fluid to perform ultrasonic cleaning on the printed model. The ultrasonic cleaning device 48 is electrically connected to an ultrasonic control board 53, which is electrically connected to a main control board. The ultrasonic main control board 53 can control the opening and closing of the ultrasonic cleaning device 48 and its working efficiency. In this embodiment, the main cleaning, pre-cleaning, and secondary cleaning are all performed using ultrasonic cleaning. Using ultrasonic cleaning can more thoroughly clean the printed model and improve cleaning efficiency.
[0056] Furthermore, the cleaning device 12 also includes a first driving device 51 and a second driving device 52. The first driving device 51 is connected to the cleaning device 12 and is adapted to drive the cleaning device 12 to start, at which time the cleaning tank 32 in the cleaning device 12 rotates around the rotating shaft 54 to clean the printed model. On the other hand, the cleaning device 12 also includes an ultrasonic control board 53, which drives the ultrasonic cleaning device 48 to start ultrasonic cleaning of the printed model. The second driving device 52 is connected to the spin-drying device 11 and is adapted to drive the spin-drying tank 22 in the spin-drying device 11 to rotate along the rotating shaft 49 to spin-dry the printed model. Through the above configuration, the cleaning device 12 can perform dual cleaning of the printed model, which helps to thoroughly clean residual printing ink from the printed model.
[0057] Furthermore, the integrated device 10 also includes a main control board 60, which includes a first drive switch 61, a second drive switch 62, and a power knob 63. The first drive switch 61 is electrically connected to the first drive device 51 and is adapted to receive a first external drive command to control the opening and closing of the first drive device 51. The second drive switch 62 is electrically connected to the second drive device 52 and is adapted to receive a second external drive command to control the opening and closing of the second drive device 52. The power knob is adapted to receive a third external drive command to adjust the drive power of the first drive device 51 and the second drive device 52.
[0058] For example, both the liquid level sensor 27 and the liquid level sensor 47 are electrically connected to the main control board 60. The liquid level sensor 27 and the liquid level sensor 47 can feed back the detected liquid level data to the main control board 60 in real time. Once the detected liquid level data exceeds the set limit, the main control board 60 will control the first drive switch 61 or the second drive switch 62 to stop the corresponding spin-drying or cleaning operation. Through the configuration of the main control board 60, the integrated device 10 can realize the integrated operation of spin-drying and cleaning of the printed model. By assembling the spin-drying device and the cleaning device in the integrated device 10, the integrated operation of spin-drying and cleaning of the printed model can be realized, improving the convenience and flexibility of the process.
[0059] In this embodiment, rotating the first drive switch 61 to the start position activates the first drive device 51 to begin cleaning the printed model. During cleaning, the cleaning power of the cleaning device 12 can be adjusted using the power knob. When cleaning is complete, rotating the first drive switch 61 to the stop position shuts off the cleaning device 12. Furthermore, when spin-drying the printing device is required, rotating the second drive switch 62 to the start position activates the second drive device 52 to begin spin-drying the printed model. The second drive device 52 drives the spin-drying drum 22 to rotate rapidly along the shaft to remove residual printing ink from the surface of the printed model. The second drive switch 62 has multiple positions to adjust the rotation speed of the spin-drying drum 22. During spin-drying, the spin-drying power of the spin-drying device 11 can be adjusted using the power knob.

Figure 10 A bottom view of the integrated device 10 is shown. (As shown) Figures 6-11 As shown, the integrated device 10 is lightweight and easy to move, with high integration and flexibility, and can be used by users with different needs.
[0061] Reference Figures 6-9 Multiple handles 71 and feet 72 are provided on the side of the all-in-one device 10. Operators can easily move the all-in-one device 10 using the handles 71, while the feet 72 further stabilize the all-in-one device 10 during the spin-drying and cleaning processes, preventing it from easily moving due to the operation of different drive mechanisms. Furthermore, referring to… Figure 10 The cleaning fluid outlet 36 and cleaning fluid inlet 37 are located at the rear of the integrated device 10, improving the aesthetics of the integrated device 10. Further reference... Figure 11 An exhaust vent 73 is provided at the bottom of the integrated device 10, which helps to dissipate heat from the integrated device 10 and further improves the service life and efficiency of the integrated device 10.
[0062] This application integrates the spin-drying device and the cleaning device into a single unit, enabling unified operation of spin-drying and cleaning of the printed model, thus improving the convenience and flexibility of the process. Furthermore, this application sets up multiple cleaning loops in the cleaning device, and further limits the cleaning fluid in at least two of the cleaning loops to be different. This ensures that the printed model is cleaned by at least two different cleaning fluids inside the cleaning device, ensuring that there is no residual printing fluid on the printed model. This greatly improves the spin-drying and cleaning effect of the printing fluid on the printed model, ensuring that the smoothness, detail accuracy, and mechanical strength of the printed model meet the design requirements.
[0063] This application, in another respect, refers to Figure 12 A spin-drying and cleaning method 20 is proposed, suitable for cleaning 3D printed models using the integrated spin-drying and cleaning device proposed in any embodiment of this application, such as the integrated device 10 described above. Flowcharts are used in this application to illustrate the operations performed by the system according to embodiments of this application. It should be understood that the preceding or following operations are not necessarily performed precisely in sequence. Instead, various steps can be processed in reverse order or simultaneously. Furthermore, other operations may be added to these processes, or one or more steps may be removed from these processes.
[0064] In this embodiment, the spin-drying and cleaning method 20 includes steps S1 and S2. Specifically, step S1 includes spin-drying the printed model using a spin-drying device; step S2 includes cleaning the spin-dried printed model using a cleaning device.
[0065] Furthermore, the cleaning process for the printed model after spin-drying includes: pre-cleaning the spin-dryed printed model using a first cleaning circuit; primary cleaning using a second cleaning circuit; and secondary cleaning using a third cleaning circuit. The first and second cleaning circuits use the same cleaning fluid, while the third cleaning circuit uses a different cleaning fluid. By performing multiple cleaning cycles and using different cleaning fluids, it is ensured that no printing ink residue remains on the printed model, thereby significantly improving the spin-drying and cleaning effect and ensuring that the smoothness, detail accuracy, and mechanical strength of the printed model meet design requirements.
[0066] The spin-drying and cleaning method 20 also includes, when the printed model is spin-dried, engaging the detachable snap-on filter with the filter snap-on part of the spin-drying device to form a spin-drying bucket; after the printed model is spin-dried, removing the detachable snap-on filter from the filter snap-on part of the spin-drying device and engaging the detachable snap-on filter with the filter snap-on part of the cleaning device to form a cleaning bucket. During the cleaning and spin-drying process of the printed model, the operator only needs to contact the detachable snap-on filter, without needing to contact the incompletely cured printed parts inside the spin-drying bucket 22. This further avoids chemical damage to the operator's skin from the printing chemicals, improving the safety of the cleaning and spin-drying process. Simultaneously, the dual-use mode of the detachable snap-on filter can further save process costs and improve the economic efficiency of the integrated equipment 10.
