Description

Technical Field

[0001] This invention relates primarily to the field of 3D printing technology, and more particularly to a transmission device, a 3D printing secondary curing oven and its control method, and electronic equipment. Background Technology

[0002] 3D printing is a rapid prototyping technology that uses digital model files as a basis and employs bondable materials such as powdered metal or plastic to construct objects layer by layer. This technology is typically implemented using digital material printers. 3D printing is commonly used in mold making, industrial design, and other fields to create models, but it is now increasingly being used for the direct manufacturing of some products.

[0003] 3D printing technology has applications in industrial design, architecture, automotive, aerospace, dentistry and medical industries, and civil engineering. Taking 3D-printed dental models as an example, 3D printing technology can be used to create dental models for dental treatments such as orthodontics, porcelain crowns, and dental implants. The main steps include: acquiring the geometric shape and structural information of the teeth through scanning or imaging; processing the acquired dental data, such as removing noise and smoothing the surface, to improve printing quality; creating a three-dimensional model of the teeth using CAD software, including the shape, size, and color; printing the model using a 3D printer, typically a high-precision, high-resolution 3D printer; and post-processing the printed model, such as cleaning, polishing, and coloring, to better simulate real teeth. The above example of a 3D-printed dental model illustrates the 3D printing process; the printing of other models follows essentially the same or similar process.

[0004] The 3D printing process also involves post-processing issues, with curing the printed parts being one of the more important steps. A secondary curing oven is a specialized auxiliary device designed and manufactured specifically for the 3D printing industry, used to dry and cure the printed 3D models. Traditional secondary curing ovens are not suitable for printing parts with no-wash resin because the printed parts will adhere to the curing tray or other support platform during the secondary curing process. Furthermore, residual liquid photosensitive resin can block the light for the next curing cycle, affecting the efficiency of the secondary curing. Summary of the Invention

The swing arm tensioning unit has two states: in the first state, when the support line is intact, it acts as a guide close to the support line; in the second state, when the support line breaks, it springs back to the limit switch unit, triggering an alarm in the limit switch unit.

[0013] Optionally, each set of the rolling components is equipped with a set of alarm components.

[0014] In a second aspect, the present invention provides a 3D printing secondary curing oven, including a conveying device as described in the first aspect, and an oven body having an inlet and an outlet, with one end of the conveying device near the inlet and the other end near the outlet.

[0017] Optionally, in the step of monitoring whether the transmission device is operating normally, if an abnormal operation of the transmission device is detected, the operation of the secondary curing oven is stopped and / or an alarm is issued.

[0018] Optionally, it also includes: controlling the secondary curing oven to perform a self-test upon startup.

[0019] Optionally, during the process of sending the products off the transmission device, it is detected whether there are still products on the transmission device that have not been successfully sent off.

[0020] Optionally, if products that have not been successfully delivered are detected on the conveying device, the operation of the secondary curing oven shall be stopped and / or an alarm shall be issued.

One end of the support line is fixed to the first active roller, the middle section passes around the driven roller, and the other end is fixed to the second active roller. The support line has a redundant section, which initially wraps around either the first or second active roller. Because the support line is used as the carrier platform for the printed parts, the printed parts will not adhere to the transmission device and can be smoothly transmitted. Furthermore, using the support line as the carrier platform for the printed parts minimizes the obstruction of lower light, thus improving the efficiency of secondary curing.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. 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.

[0051] 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. In addition, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application's specification may have been chosen by the applicant according to his or her judgment, and their detailed meanings are explained in the relevant sections of this description. Moreover, this application should be understood not only through the actual terms used, but also through the meaning implied by each term.

[0052] 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 in exact order. 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.

[0053] Example 1

[0054] refer to Figures 1-5As shown, the transmission device 200 provided in this embodiment includes several sets of rolling components 210 arranged side by side. Each rolling component 210 includes a first driving roller 211, a second driving roller 212, a driven roller 213, and a support line 214. One end of the support line 214 is fixed to the first driving roller 211, the middle section passes around the driven roller 212, and the other end is fixed to the second driving roller 213. The support line 214 has a redundant section, which initially wraps around either the first driving roller 211 or the second driving roller 212. Figure 2 Point A in the middle represents the redundant section of the winding.

[0055] In this embodiment, the portion of the transmission device 200 that serves as the carrying platform is not a traditional conveyor belt, but rather a support line 214. When the first drive roller 211 rotates, the support line 214 is wound around it, and the support line 214 wound around the second drive roller 212 is released, thus causing the support line 214 to move in one direction. Conversely, when the second drive roller 212 rotates, the support line 214 is wound around it, and the support line 214 wound around the first drive roller 211 is released, thus causing the support line 214 to move in the other direction, thereby driving the object to be cured 20 on the support line 214 to move synchronously.

[0056] When there are multiple sets of rolling components 210, the multiple sets of rolling components 210 are arranged side by side, and a bearing platform can be formed by multiple support lines 214. Of course, this bearing platform has gaps, but it does not prevent the object to be cured 20 from being placed on it and transported.

[0057] Because the support line 214 is used as the carrier platform for the material to be cured 20, the material to be cured 20 will not adhere to the transmission device 200 and can be transmitted smoothly. In addition, the transmission device 200 uses the support line 214 as the carrier platform for the printed parts, which can minimize the obstruction of the lower light and improve the efficiency of secondary curing.

[0058] In one example, the first driving roller 211 and the second driving roller 212 are on the same side and arranged coaxially, while the driven roller 213 is on the other side.

[0059] The first active roller 211 and the second active roller 212 can be arranged on the same side or on different sides. Theoretically, as long as the support line 214 can reciprocate, it is acceptable. In this embodiment, the first active roller 211 and the second active roller 212 are on the same side and their rotating shafts are coaxially arranged (e.g., Figure 1The Z-axis is a rotating axis. Its advantage is that it reduces the overall length of the transmission device 200, that is, it reduces the space occupied by the transmission device 200. In addition, the driving devices of the first active roller 211 and the second active roller 212 can also be set on the same side, which obviously makes the structure of the transmission device 200 more compact and can be applied in more application scenarios.

[0060] In one example, the support wire 214 is a steel wire or a polymer wire.

[0061] The support wire 214 is primarily selected based on two factors: strength and temperature resistance. Strength is considered to ensure effective support for the material to be cured 20, while temperature resistance is taken into account to adapt to the furnace environment. Steel wire offers advantages such as very high tensile strength, capable of withstanding significant tensile and compressive forces, and good toughness, making it resistant to breakage or deformation under impact or vibration. Polymer wire is lighter than traditional metal wire, reducing equipment weight and facilitating handling and installation. Furthermore, polymer wire exhibits good tensile strength and fatigue resistance, enabling it to withstand substantial tensile and compressive forces. Of course, considering various factors, such as cost, a suitable material for the support wire 214 should be chosen to meet different usage conditions and requirements.

[0062] In this embodiment, steel wire or polymer wire can be used as support wire 214 to transport and lift the no-wash curable material 20 for curing. Since there are large gaps between the wires, the light below can be avoided to the greatest extent, so that the secondary curing oven has better light curing efficiency.

[0063] In one example, the first drive roller 211 and / or the second drive roller 212 have a snap fastener 2151, which is connected to a bolt 2152. The two ends of the support line 214 are respectively fitted onto the corresponding bolts 2152. The combination of the snap fastener 2151 and the bolt 2152 can be referred to as the snap-fit ​​component 215.

[0064] In this embodiment, one end of the support line 214 is fixed to the first drive wheel 211 by a snap-fit ​​215 and rotated by the driven wheel 213, while the other end is fixed to the second drive wheel 212 by another snap-fit ​​215, thereby realizing the reciprocating function of the support line 214.

[0065] In one example, a first guide post 216 is provided next to the first drive roller 211 and / or a second guide post 217 is provided next to the second drive roller 212.

[0066] In this embodiment, a support line 214 is used as a transmission component. During the rotation of the first drive wheel 211 or the second drive wheel 212, the support line 214 will experience some swaying or offset between the winding gaps of the first drive wheel 211 or the second drive wheel 212, which is detrimental to stabilizing the object to be cured 20 on the support line 214. In this embodiment, the transmission device 200 is equipped with guide posts (including a first guide post 216 and a second guide post 217) to ensure that the support line 214 can move back and forth along a predetermined route. Simultaneously, the guide posts can also provide additional support and stability, preventing the support line 214 from lateral offset or folding during operation. Therefore, the guide posts are of great importance in ensuring the normal operation of the support line 214.

[0067] In one example, a third guide post 218 is provided next to the driven roller 213 to ensure that the support line 214 can move back and forth along a predetermined route.

[0068] In one example, the transmission device 200 is further provided with an alarm component 219, which includes a swing arm tensioning unit 2191 and a limit switch unit 2193. One end of the swing arm tensioning unit 2191 is connected to the rotating shaft 2192, and the other end is placed on the support line 214. The swing arm tensioning unit 2191 has two states: in the first state, when the support line 214 is intact, it acts as a tensioner, closely attached to the support line 214; in the second state, when the support line 214 breaks, it springs back to the limit switch unit 2193, triggering an alarm in the limit switch unit 2193. Figure 5 The direction of the middle arrow indicates that when the support line 214 breaks, the swing arm tensioning unit 2191 rebounds to the limit switch unit 2193.

[0069] In one example, each set of scrolling components 210 is equipped with a set of alarm components 219.

[0070] In some cases, even if the support line 214 of a certain group of rolling components 210 breaks, the other rolling components 210 can still operate normally. In reality, this creates a safety hazard for the transmission device 200, and the material to be cured 20 on that group of rolling components 210 may fall off. To monitor each group of rolling components 210, an alarm device 219 can be installed for each group. This allows for timely detection of any broken support line 214 in any group of rolling components during the operation of the transmission device 200, enabling prompt maintenance of the transmission device 200 and preventing further damage.

[0071] The transmission device 200 provided in this embodiment includes several sets of rolling components 210 arranged side by side, including a first active roller 211, a second active roller 212, a driven roller 213, and a support line 214. One end of the support line 214 is fixed to the first active roller 211, the middle section passes around the driven roller 213, and the other end is fixed to the second active roller 212. The support line 214 has a redundant section, which initially wraps around the first active roller 211 and / or the second active roller 212. Because the support line 214 is used as a carrying platform for the material to be cured 20, the material to be cured 20 will not adhere to the transmission device 200 and can be smoothly transmitted. Furthermore, the use of the support line 214 as a carrying platform for the material to be cured 20 in the transmission device 200 can minimize the obstruction of lower light, which is beneficial to improving the efficiency of secondary curing.

[0072] Example 2

[0073] Figure 6 This is a schematic diagram of the structure of a 3D printing secondary curing oven according to an embodiment of the present invention. Figure 7 This is a simplified structural diagram of a 3D printing secondary curing oven according to an embodiment of the present invention, combined with... Figure 1 and Figure 2 This embodiment describes the structure of the 3D printing secondary curing oven 10. Its structure mainly includes an oven body 100, which has an inlet 110 and an outlet 120, as well as a transfer device. The transfer device shown can be the transfer device 200 as shown in Embodiment 1. One end (T1) of the transfer device 200 is close to the inlet 110, and the other end (T2) is close to the outlet 120.

[0074] When the 3D printing secondary curing oven 10 is working, one end of the conveying device 200 is close to the inlet 110 and the other end is close to the outlet 120. The material to be cured 20 is input from the inlet 110 and the cured product is sent out from the outlet 120.

[0075] In one example, a first photodetector 300 is disposed inside the furnace body 100 above the support line 214 and / or a second photodetector 400 is disposed below the support line 214.

[0076] In this embodiment, the first photodetector 300 is used to detect whether the material to be cured 20 has fallen off the support line 214 or other abnormalities when it is being transferred to the secondary curing oven. The second photodetector 400 is used to detect whether the material to be cured 20 has fallen below the support line 214. For example, the first photodetector 300 is provided above the transmission device 200. When the transmission device 200 starts operating, the first drive wheel 211 is in the retracting state, and the second drive wheel 212 is in the retracting state, driving the material to be cured 20 towards the outlet 120 of the secondary curing oven. When the curing operation is completed, the second drive wheel 212 is in the releasing state, and the first drive wheel 211 is in the retracting state. During the retraction process of the support line 214, the second photodetector detects whether any product is missing from the support line 214.

[0077] Other details of the transmission device 200 in this embodiment can be found in the foregoing embodiments, and will not be elaborated here.

[0078] The 3D printing secondary curing oven 10 provided in this embodiment has a conveying device 200 with several sets of rolling components 210 arranged side by side, including a first active roller 211, a second active roller 212, a driven roller 213, and a support line 214. One end of the support line 214 is fixed to the first active roller 211, the middle section passes around the driven roller 213, and the other end is fixed to the second active roller 212. The support line 214 has a redundant section, which initially wraps around the first active roller 211 and / or the second active roller 212. Because the support line 214 is used as a carrying platform for the object to be cured 20, the object to be cured 20 will not adhere to the conveying device 200 and can be smoothly conveyed out. Furthermore, the use of the support line 214 as a carrying platform for the object to be cured in the conveying device 200 can minimize the obstruction of lower light, which is beneficial to improving the efficiency of secondary curing.

[0079] Example 3

[0080] Figure 8 This is a flowchart illustrating a control method for a 3D printing secondary curing oven according to an embodiment of the present invention. (Refer to...) Figure 8 As shown, method 800 can be applied to the secondary curing oven as shown in Example 2, but is not limited thereto, and includes: S810, monitoring whether the transmission device is operating normally; if the transmission device is operating normally, starting the transmission device to bring the material to be cured into the secondary curing oven; S820, closing the oven door of the secondary curing oven and filling the secondary curing oven with inert gas; S830, turning on the light source of the secondary curing oven when the inert gas is injected to a preset pressure; S840, starting to depressurize after the preset curing time is completed, and opening the oven door when the pressure is balanced to send the product on the transmission device away.

[0081] In this embodiment, to ensure the effective execution of the photocuring process, the photocuring process can be automatically controlled. The preset execution program sequentially controls the opening and closing of each component / assembly in the secondary curing oven, which can not only improve work efficiency but also ensure product quality.

[0082] It is understood that the entire curing process of the secondary curing oven can be regarded as an operation process and a working process. It can be seen that the steps described in the above method 800 are actually various execution nodes controlled by software or program, i.e., the operation process, while the working process is the continuous process between the nodes, such as transmission, heating, light curing, etc. Although the working process is not directly controlled by software or program compared to the operation process, it is also part of the secondary curing process in this embodiment. Those skilled in the art can understand that the method 800 in this embodiment essentially includes the entire process (operation process and working process).

[0083] For example, the control program or software of method 800 in this embodiment can be written in C language, but is not limited to this language. Different programming languages ​​are not necessarily related to the implementation of method 800 and the operating efficiency of the secondary curing oven.

[0084] In one example, during the step of monitoring whether the conveyor is operating normally, if an abnormality is detected in the conveyor, the operation of the secondary curing oven is stopped and / or an alarm is issued.

[0085] In one example, method 800 further includes controlling the secondary curing oven to perform a power-on self-test.

[0086] The self-inspection process checks various functions of the secondary curing oven, including the control and heating systems, ensuring the oven is in a safe condition before normal operation. During the self-inspection, faults in the secondary curing oven can also be diagnosed and located, allowing for timely detection and resolution of potential problems, preventing malfunctions during operation that could impact production efficiency and product quality.

[0087] In one example, method 800 further includes detecting whether there are still undelivered products on the conveyor during the process of conveying products away from the conveyor. This detection process is generally implemented by a photodetector; for example, if cured products are detected on the conveyor during the process of resetting the conveyor, it indicates that some products were not successfully conveyed during product transport. These situations require timely maintenance of the secondary curing oven to prevent damage to the secondary curing oven from falling materials / products.

[0088] The control method for the 3D printing secondary curing oven provided in this embodiment uses an improved transmission device, which prevents the material to be cured from adhering to the transmission device and allows it to be smoothly transported out. Furthermore, the transmission device uses a support line as a platform to support the material to be cured, which can minimize the obstruction of light from below and improve the efficiency of secondary curing.

[0089] Example 4

[0090] Figure 9 This is a schematic diagram of the control device for a 3D printing secondary curing oven according to an embodiment of the present invention. (Refer to...) Figure 9 As shown, the device 900 mainly includes: a start-up module 901, used to monitor whether the transmission device is operating normally; when the transmission device is operating normally, start the transmission device to bring the material to be cured into the secondary curing oven; a gas filling module 902, used to close the oven door of the secondary curing oven and fill the secondary curing oven with inert gas; a light start-up module 903, used to turn on the light source of the secondary curing oven when the inert gas is injected to a preset pressure; a stop module 904, used to turn on the light source of the secondary curing oven when the inert gas is injected to a preset pressure; and a stop module 905, used to start depressurizing after the preset curing time is completed, and open the oven door when the pressure is balanced to send the product on the transmission device away.
