Description

Technical Field

[0001] The present application mainly relates to the field of three-dimensional printing technology, and in particular to a spin-drying and cleaning integrated device and a spin-drying and cleaning method. Background Art

[0002] With the widespread application of digitalization, the application of photocuring 3D printing is becoming more and more extensive. In 3D printing technology, printing liquid plays an important role as a core material. Its core role is to serve as a photosensitive material, that is, it is selectively cured layer by layer through light of a specific wavelength (such as UV laser or projection), converting from liquid to solid to accurately construct a three-dimensional entity. The characteristics of the printing liquid directly determine the accuracy, mechanical strength, surface quality and functionality (such as toughness, temperature resistance, and biocompatibility) of the printed model. It is a key basic material that affects the performance and scope of application of the final product. After the 3D printing is completed, the residual resin on the model needs to be cleaned off in time to ensure the safety and durability of the finished product, avoid health risks and failure of subsequent processes.

[0003] Existing printing model drying devices and cleaning devices usually use two independent machines to work, and the cleaning device usually only uses a single cleaning liquid for cleaning. Using a single cleaning liquid for cleaning cannot ensure that the cleaning is in place, nor can it ensure that there is no residual printing liquid on the printed model. Furthermore, the existing technology usually uses oil or alcohol as a cleaning liquid, which is not only expensive, but also has certain risks. In addition, the printed model after cleaning with oil or alcohol usually has an unremovable odor, which affects the user experience. Furthermore, the solidified printing liquid will usually form a sticky layer or white patches on the printed model, destroying the model's smoothness and detail accuracy. The residual printing liquid will further hinder the complete curing of the print, resulting in problems such as weakened mechanical strength of the component, easy brittle cracking or deformation. Furthermore, uncleaned printing liquid will also pollute the working environment or contaminate other items, thereby accelerating the aging of tool consumables. Summary of the Invention

[0036] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0037] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0038] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

Furthermore, this application should be understood not only by the actual terms used, but also by the meaning implied by each term.

[0041] This application refers to Figures 1 to 11 A drying and cleaning integrated device 10 (hereinafter referred to as "integrated device 10") is proposed. The drying and cleaning integrated device proposed in any embodiment of the present application is suitable for drying and cleaning the printed model after three-dimensional printing. Figures 1 to 5 Introducing the integrated device 10. Among them, Figure 1 and Figure 2 The internal perspective structure diagram of the integrated device 10 is shown when the drying device cover 21 of the drying device 11 and the cleaning device cover 31 of the cleaning device 12 are opened. Figure 3 and Figure 4 The internal perspective structure diagram of the integrated device 10 is shown when the drying device cover 21 of the drying device 11 and the cleaning device cover 31 of the cleaning device 12 are closed. Figure 5 FIG. 2 shows a schematic diagram of the specific structure of the cleaning device 12 .

[0042] First refer to Figures 1 to 4 The integrated device 10 mainly includes a drying device 11 and a cleaning device 12. The specific structure of the drying device 11 will be described first. The drying device 11 is suitable for drying printed models (not shown). When the drying device 11 is in the drying state, it is loaded with a drying bucket 22, and the printed models are suitable for being placed in the drying bucket 22 for drying.

[0043] The drying device 12 includes a drying device cover 21, which includes a groove 23. When the printed model is placed in the drying bucket 22 for drying, the drying device cover 21 is closed. At this time, the groove 23 on the drying device cover 21 corresponds to the drying bucket 22 in spatial position. In this embodiment, the inner wall of the groove 23 includes a groove sealing ring 24. When the printed model is dried in the drying bucket 22, the groove sealing ring 24 can seal the joint between the drying bucket 22 and the groove 23, ensuring that the printing liquid remaining in the printed model during the drying process will not be ejected from the joint between the drying bucket 22 and the groove 23, ensuring that the printing liquid remaining in the printed model remains in the drying bucket 22 for subsequent recovery.

[0044] Furthermore, in this embodiment, the drying barrel 22 may be a detachable card filter. Figure 2 The filter screen has multiple filter openings 28. When the printed model is spun in the spin-drying tub 22, any residual liquid on the printed model is ejected through the filter openings 28 and ultimately flows out through the spin-drying tub outlet 25, which is connected to a dewatering trough (not shown) on the spin-drying device 11. The spin-drying device 11 includes a recovery cup 26 and a liquid level sensor 27. The recovery cup 26 includes a recovery cup liquid collection tube (not shown) connected to the spin-drying tub outlet 25. Printing liquid ejected from the printed model during the spin-drying process can flow into the recovery cup 26 through the spin-drying tub outlet 25. The liquid level sensor 27 is adapted to detect the level of the recovered printing liquid within the recovery cup 26.

[0045] In this embodiment, by providing the recovery cup 26, the residual printing liquid on the printed model can be further recovered, and the collected residual printing liquid can be used to print other printed models, which can save costs to a certain extent and achieve technical effects such as environmental protection. Furthermore, the integrated device 10 also includes an alarm device, which includes an alarm signal light 29. When the liquid level sensor 27 detects that the printing liquid in the recovery cup 26 exceeds a certain liquid level threshold, the alarm signal light 29 will light up to sound an alarm, reminding the staff to promptly recover the printing liquid in the recovery cup 26 and prepare for a new round of liquid recovery work. For example, the liquid level threshold can be flexibly adjusted according to the actual application situation, and this application does not impose any restrictions on this.

[0046] Continue to refer to Figures 1 to 5 , now combined Figures 1 to 5 The specific structure of the cleaning device 12 in the integrated device 10 is specifically introduced. After the printed model is spun dry by the drying device 11, it can be placed in the cleaning device 12 for cleaning. In this embodiment, preferably, the drying device 11 and the cleaning device 12 respectively include a filter clamping portion (not shown). As mentioned above, the drying bucket 22 in the drying device 11 in this embodiment is a detachable clamping filter. When the printed model is spun dry, the detachable clamping filter is clamped with the filter clamping portion of the drying device to serve as the drying bucket 22. After the printed model is dried, the detachable clamping filter is removed from the filter clamping portion of the drying device 11, and the detachable clamping filter is clamped with the filter clamping portion of the cleaning device 12 to serve as the cleaning bucket 32.

[0047] With the above design, workers only need to touch the detachable snap-on filter during the cleaning and drying process of the printed model, without having to touch the uncured printed part in the drying tub 22. This can further prevent chemical damage to the worker's skin caused by the printing liquid, improve the safety of cleaning and drying, and the dual-use mode of the detachable snap-on filter can further save process costs and improve the economic efficiency of the integrated device 10. In other embodiments of the present application, the drying tub 22 and the cleaning tub 32 can also use different filters, and this application does not impose any restrictions on this.

[0048] Furthermore, the cleaning device 12 includes a plurality of cleaning circuits 33 (see Figure 5), the cleaning device 12 is loaded with a cleaning bucket 32 ​​in the cleaning state. The printed model is suitable for being placed inside the cleaning bucket 32 ​​for cleaning. The cleaning bucket 32 ​​is connected to multiple cleaning circuits 33, which are suitable for injecting and recovering cleaning fluid into the cleaning bucket 32. At least two of the cleaning circuits use different cleaning fluids. By providing at least two cleaning circuits with different cleaning fluids, the printed model is further ensured to be cleaned with at least two different cleaning fluids within the cleaning device. This ensures that no residual printing fluid remains on the printed model, thereby significantly improving the drying and cleaning effect of the printing fluid on the printed model and ensuring that the printed model's finish, detail accuracy, and mechanical strength meet design requirements.

[0049] 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. Among them, the first cleaning circuit 41 includes a first cleaning liquid, the second cleaning circuit 42 includes a second cleaning liquid, and the third cleaning circuit 43 includes a third cleaning liquid. In this embodiment, the first cleaning liquid is the same as the second cleaning liquid. Furthermore, the third cleaning liquid is different from the first cleaning liquid and the second cleaning liquid. Exemplarily, the first cleaning liquid and the second cleaning liquid are odorless liquids with low cost and high safety factor, and the third cleaning liquid is water, which can further ensure the cleaning safety of the printed model, and can also ensure that the printed model after cleaning by the all-in-one device 10 will not have an unacceptable odor, further improving the user experience and the safety factor of cleaning.

[0050] In this embodiment, the first cleaning circuit 41 is preferably adapted to inject and recover a first cleaning liquid into and from the spun-dried printed model for pre-cleaning; the second cleaning circuit 42 is adapted to inject and recover a second cleaning liquid into and from the pre-cleaned printed model for main cleaning; and the third cleaning circuit 43 is adapted to inject and recover a third cleaning liquid into and from the main-cleaned printed model for secondary cleaning. The three cleaning processes of pre-cleaning, main cleaning, and secondary cleaning thoroughly clean the printed model, further ensuring that no residual printing liquid remains on the printed model, thereby significantly improving the cleaning effect of the printing liquid on the printed model.

[0051] In this embodiment, each cleaning circuit 33 includes a circuit liquid inlet 34 and a circuit liquid outlet 35, and the cleaning device 12 includes a cleaning liquid outlet 36 and multiple cleaning liquid inlets 37, wherein the multiple cleaning liquid inlets 37 are respectively connected to the multiple circuit liquid outlets 35 of the multiple cleaning circuits 33, and the cleaning liquid outlet 36 is connected to the multiple circuit liquid inlets 34 of the multiple cleaning circuits 33.

[0052] Furthermore, each cleaning circuit 33 includes a booster pump 38, a cleaning liquid storage chamber 39, and a solenoid valve 30. The booster pump 38 is connected to the storage chamber outlet 44 of the cleaning liquid storage chamber 39 and the circuit outlet 35. The booster pump 38 is adapted to pump cleaning liquid stored in the cleaning liquid storage chamber 39 into the cleaning liquid inlet 37 through the circuit outlet 35. The solenoid valve 30 is connected to the storage chamber inlet 45 of the cleaning liquid storage chamber 39 and the circuit inlet 34. When cleaning liquid is discharged from the cleaning liquid outlet 36, the solenoid valve 30 opens to recover the cleaning liquid into the corresponding cleaning liquid storage chamber 39. The arrangement of the booster pump 38, the cleaning liquid storage chamber 39, and the solenoid valve 30 enables the injection and recovery of cleaning liquid within the cleaning circuit 33, enabling the recycling of cleaning liquid, further saving costs and improving the economic benefits of the integrated device 10.

[0053] We will continue to refer to Figure 5 The injection and recovery process of the cleaning fluid is described in detail. Figure 5 As shown, taking the first cleaning circuit 41 as an example, the cleaning liquid storage chamber 39 in the first cleaning circuit 41 stores a first cleaning liquid (correspondingly, the cleaning liquid storage chamber 39 in the second cleaning circuit 41 stores a second cleaning liquid identical to the first cleaning liquid, and the cleaning liquid storage chamber 39 in the third cleaning circuit 43 stores water). When the cleaning operation begins, the first cleaning liquid in the cleaning liquid storage chamber 39 in 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 connecting the cleaning liquid storage chamber 39 to the booster pump 38. The booster pump 38 of the first cleaning circuit 41 pumps the first cleaning liquid into the cleaning bucket 32 ​​to perform the first pre-cleaning of the printed model.

[0054] Furthermore, after the main cleaning of the printed model is completed, the first cleaning liquid located in the cleaning bucket 32 ​​will flow out to the circuit liquid inlet 34 through the cleaning liquid outlet 36. At this time, since the printed model is pre-cleaned, the solenoid valves 30 on the second cleaning circuit 42 and the third cleaning circuit 43 are in a closed state, and the solenoid valve 30 on the first cleaning circuit 41 is in an open state. The first cleaning liquid flowing out of the cleaning liquid outlet 36 will finally flow into the cleaning liquid storage chamber 39 in the first cleaning circuit 41 connected to the solenoid valve 30 through the solenoid valve 30, and then the second main cleaning is performed.

[0055] In this embodiment, a circulation pump 46 and a liquid level sensor 47 are preferably provided between the cleaning liquid outlet 36 and the circuit liquid inlet 34. Taking the main cleaning process as an example, during the main cleaning process, the first cleaning liquid flowing out of the cleaning liquid outlet 36 first flows into the circulation pump 46. The circulation pump 46 can then pump the recovered first cleaning liquid into the cleaning liquid storage chamber 39. The liquid level sensor 47 is adapted to detect the cleaning liquid level within the cleaning barrel 32 to ensure that the cleaning liquid does not overflow from the cleaning barrel 32.

[0056] Exemplarily, the circulation pump 46 is a device that is at least partially transparent. The staff can observe the turbidity of the first cleaning liquid after flowing out of the cleaning liquid outlet 36 through the circulation pump 46 to determine whether the first cleaning liquid needs to be replaced. If the turbidity of the first cleaning liquid is low, the circulation pump 46 can pump the recovered first cleaning liquid into the cleaning liquid storage chamber 39. If the turbidity of the first cleaning liquid is high, the staff can replace the first cleaning liquid as appropriate to ensure that the printed model can be cleaned more thoroughly.

[0057] In this embodiment, the second main cleaning and the third secondary cleaning process can refer to the cleaning process of the main cleaning, and will not be described in detail here. Further, 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 the present application, the cleaning circuits 33 with the same cleaning liquid (for example, the first cleaning circuit 41 and the second cleaning circuit 42 in this embodiment) can have a connection relationship, that is, when the cleaning liquid of a cleaning circuit is insufficient or the turbidity is high, the cleaning liquid in the cleaning circuit with the same cleaning liquid as the cleaning circuit can be pumped into the cleaning barrel 32 for cleaning, thereby further saving the amount of cleaning liquid and reducing process costs.

[0058] On the other hand, the cleaning device 12 further includes a cleaning device cover 31, referring to Figure 3 and Figure 4 When the cleaning device 12 is working, the cleaning device cover 31 is located above the cleaning bucket 32. Figure 1 and Figure 2 The cleaning device cover 31 is provided with an ultrasonic cleaning device 48. This device is adapted to extend into the cleaning bucket 32 ​​and contact the cleaning fluid to ultrasonically clean the printed model. The ultrasonic cleaning device 48 is electrically connected to an ultrasonic control board 53, which is in turn electrically connected to a main control board. The ultrasonic main control board 53 controls the on / off state of the ultrasonic cleaning device 48, as well as its operating efficiency. In this embodiment, the main cleaning, pre-cleaning, and secondary cleaning are all performed using ultrasonic cleaning. Ultrasonic cleaning provides a more thorough cleaning of the printed model, improving cleaning efficiency.

[0059] Furthermore, the cleaning device 12 also includes a first drive device 51 and a second drive device 52. The first drive device 51 is connected to the cleaning device 12 and is adapted to drive the cleaning device 12 to start, at which point the cleaning bucket 32 ​​in the cleaning device 12 rotates about 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 ultrasonically cleaning the printed model. The second drive device 52 is connected to the drying device 11 and is adapted to drive the drying bucket 22 in the drying device 11 to rotate along the rotating shaft 49 to dry the printed model. Through the above arrangement, the cleaning device 12 can perform a double cleaning of the printed model, helping to thoroughly clean any residual printing liquid on the printed model.

[0060] 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, wherein the first drive switch 61 is electrically connected to the first drive device 51, and the first drive switch 61 is suitable for receiving a first external drive instruction 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 the second drive switch 62 is suitable for receiving a second external drive instruction to control the opening and closing of the second drive device 52; the power knob is suitable for receiving a third external drive instruction to adjust the driving power of the first drive device 51 and the second drive device 52.

[0061] 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 provide real-time feedback of the detected liquid level data to the main control board 60. Once the liquid level data exceeds a set limit, the main control board 60 controls the first drive switch 61 or the second drive switch 62 to stop the corresponding spin-drying or cleaning operation. The configuration of the main control board 60 enables the integrated device 10 to perform an integrated spin-drying and cleaning operation on the printed model. By assembling both the spin-drying device and the cleaning device in the integrated device 10, the integrated spin-drying and cleaning operation of the printed model can be achieved, improving the convenience and flexibility of the process.

[0062] In this embodiment, when the first drive switch 61 is rotated to the start position, the first drive device 51 is immediately activated to start the cleaning operation of the printed model. During the cleaning process, the cleaning power of the cleaning device 12 can be adjusted by adjusting the power knob. When the cleaning is completed, the first drive switch 61 can be rotated to the off position to shut down the cleaning device 12. Furthermore, when it is necessary to spin dry the printing device, the second drive switch 62 is rotated to the start position, and the second drive device 52 is immediately activated to start the spin drying operation of the printed model. The second drive device 52 drives the spin drying barrel 22 to rotate rapidly along the rotating shaft to remove the printing liquid remaining on the surface of the printed model. The second drive switch 62 is provided with multiple gears, which can adjust the speed of the spin drying barrel 22. During the spin drying process, the spin power of the spin drying device 11 can be adjusted by adjusting the power knob. When the spin drying is completed, the second drive switch 62 is rotated to the off position to shut down the spin drying device 12.

[0065] The present application integrates the drying device and the cleaning device in the same device to realize the integrated operation of drying and cleaning the printed model, thereby improving the convenience and flexibility of the process. Furthermore, the present application sets up multiple cleaning circuits in the cleaning device, and further limits the cleaning liquids of at least two of the cleaning circuits to different ones, which can further ensure that the printed model is cleaned with at least two different cleaning liquids inside the cleaning device, and can ensure that there will be no residual printing liquid on the printed model, thereby greatly improving the drying and cleaning effect of the printing liquid on the printed model, and ensuring that the smoothness, detail accuracy and mechanical strength of the printed model meet the design requirements.

[0066] This application also refers to Figure 12 A spin-drying and cleaning method 20 is proposed, which is suitable for cleaning a three-dimensional printed model using a spin-drying and cleaning integrated device proposed in any embodiment of the present 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 the embodiments of the present application. It should be understood that the previous or following operations are not necessarily performed in exact sequence. Instead, various steps can be processed in reverse order or simultaneously. At the same time, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0067] In this embodiment, the spin-drying and cleaning method 20 includes steps S1 and S2. Specifically, step S1 includes spinning the printed model by a spin-drying device; and step S2 includes cleaning the printed model after spinning by a cleaning device.

[0068] Furthermore, the cleaning device for cleaning the printed model after spin-drying also includes: using a first cleaning circuit to pre-clean the printed model after spin-drying; using a second cleaning circuit to perform a main clean on the printed model after the pre-cleaning; and using a third cleaning circuit to perform a secondary clean on the printed model after the main clean. The first and second cleaning circuits use the same cleaning fluid, while the third cleaning circuit uses a different cleaning fluid than the first and second cleaning circuits. Multiple cleanings and cleaning the printed model with different cleaning fluids ensure that no residual printing fluid remains on the printed model, thereby greatly improving the drying and cleaning effect of the printing fluid on the printed model and ensuring that the smoothness, detail accuracy, and mechanical strength of the printed model meet design requirements.

[0069] The spin-drying and cleaning method 20 further includes, when the printed model is being spun-dried, snapping the detachable snap-on filter screen onto the filter snap-on portion of the drying device to form a spin-drying bucket; after the printed model is spun-dried, removing the detachable snap-on filter screen from the filter snap-on portion of the drying device, and snapping the detachable snap-on filter screen onto the filter snap-on portion of the cleaning device to form a cleaning bucket. During the cleaning and spin-drying process of the printed model, the staff only needs to touch the detachable snap-on filter screen, without having to touch the uncured printed part in the spin-drying bucket 22. This can further prevent chemical damage to the staff's skin caused by the printing liquid, improve the safety of the cleaning and drying process, and at the same time, the dual-use mode of the detachable snap-on filter screen can further save process costs and improve the economic efficiency of the integrated device 10.
