Description

Transmission device, 3D printing secondary curing furnace and control method thereof, and electronic equipment Technical Field

[0001] The present invention relates to the field of 3D printing technology, and in particular to a transmission device, a 3D printing secondary curing furnace and a control method thereof, and electronic equipment. Background Art

[0002] 3D printing is a rapid prototyping technology that uses digital model files as a foundation and uses 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 to create models in fields such as mold making and industrial design, but is now increasingly being used for the direct manufacture of some products.

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

[0004] The entire 3D printing process also involves post-processing, with curing being a crucial step. A secondary curing oven is a specialized piece of auxiliary equipment designed and manufactured specifically for the 3D printing industry, used to dry and cure printed 3D models. Traditional secondary curing ovens are not suitable for prints made with wash-free resins because the prints adhere to the curing tray and other supporting platforms during secondary curing. Furthermore, residual liquid photosensitive resin can block the light used for the next curing step, affecting secondary curing efficiency.

[0053] Example 1

[0054] 1 to 5 , the transmission device 200 provided in this embodiment includes a plurality of groups of rolling components 210 arranged side by side. The rolling components 210 include a first active roller 211, a second active roller 212, a driven roller 213, and a support wire 214. One end of the support wire 214 is fixed to the first active roller 211, the middle section is wound around the driven roller 212, and the other end is fixed to the second active roller 213. The support wire 214 has a redundant section, and the redundant section of the support wire 214 is initially wound around the first active roller 211 or the second active roller 212, as shown in A in FIG2 .

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

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

[0057] Since the support line 214 is used as the supporting platform for the object to be cured 20, the object to be cured 20 will not adhere to the transmission device 200 and can be smoothly transmitted out. In addition, the transmission device 200 uses the support line 214 as the printed part supporting platform, which can avoid blocking the lower light to the greatest extent, which is conducive to improving the secondary curing efficiency.

[0058] In one example, the first driving roller 211 and the second driving roller 212 are on the same side with their rotation axes coaxially arranged, and 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 be moved back and forth, it can be sufficient. In this embodiment, the first active roller 211 and the second active roller 212 are arranged on the same side and the rotating shafts are arranged coaxially (such as the Z-axis in Figure 1 is the rotating shaft). This has the advantage of reducing the layout length of the entire transmission device 200, that is, reducing 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 arranged on the same side. Obviously, this can make the structure of the transmission device 200 more compact and applicable to more usage scenarios.

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

[0061] The support wire 214 mainly considers its strength and temperature resistance. On the one hand, its strength is considered so that it can form a good support effect for the object to be cured 20. On the other hand, the temperature is considered so that it can adapt to the environment in the furnace. The advantage of steel wire is that it has very high tensile strength and can withstand a large amount of tension and pressure. The steel wire has good toughness and is not easy to break or deform when impacted or vibrated. The advantage of polymer wire is that it is lighter than traditional metal wire, which can reduce the weight of the equipment and facilitate transportation and installation. In addition, polymer wire has good tensile strength and fatigue resistance and can withstand large tension and pressure. Of course, considering many factors, such as cost, etc., a support wire 214 of suitable material is used to meet different usage conditions and requirements.

[0062] In this embodiment, steel wire or polymer wire can be used as the support wire 214 to transmit and drag the wash-free object to be cured 20 for curing. Since there are large gaps between the wires, it can avoid blocking the lower light to the greatest extent, so that the secondary curing furnace has better light curing efficiency.

[0063] In one example, the first active roller 211 and / or the second active roller 212 has a buckle 2151, which is connected to a bolt 2152. The two ends of the support wire 214 are respectively sleeved on the corresponding bolts 2152. The combination of the buckle 2151 and the bolt 2152 can be called a clamping member 215.

[0064] In this embodiment, one end of the support line 214 is fixed to the first driving wheel 211 through a clamping member 215 and is turned through the driven wheel 213, and the other end is fixed to the second driving wheel 212 through another clamping member 215, so that the support line 214 can realize the round-trip function.

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

[0066] In this embodiment, a support line 214 is used as a transmission member. During the rotation of the first driving wheel 211 or the second driving wheel 212, the support line 214 will have a certain shaking or offset between the winding gaps of the first driving wheel 211 or the second driving wheel 212, which is not conducive to stabilizing the object to be solidified 20 on the support line 214. The transmission device 200 of this embodiment is provided with a guide column (including a first guide column 216 and a second guide column 217) to ensure that the support line 214 can move back and forth along a predetermined route. At the same time, the guide column can also provide additional support and stability to prevent the support line 214 from lateral offset or folding during operation. Therefore, the guide column is of great significance for 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 equipped 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 a rotating shaft 2192, and the other end is placed on the support wire 214. The swing arm tensioning unit 2191 has two states: in the first state, when the support wire 214 is intact, it clings to the support wire 214, providing tension; in the second state, when the support wire 214 breaks, it rebounds toward the limit switch unit 2193, triggering an alarm from the limit switch unit 2193. The arrow in Figure 5 indicates that when the support wire 214 breaks, the swing arm tensioning unit 2191 rebounds toward the limit switch unit 2193.

[0069] In one example, each set of rolling components 210 is provided with a set of warning components 219 .

[0070] In some cases, even if the support wire 214 of a certain group of rolling components 210 breaks, the other rolling components 210 can still operate normally. In fact, at this time, the transmission device 200 has already posed a safety hazard, and the objects to be cured 20 on the group of rolling components 210 may also fall. In order to monitor each group of rolling components 210, each group of rolling components 210 can be equipped with a set of alarm components 219. Then, during the operation of the transmission device 200, no matter which group of rolling components 210 has a broken support wire 214, it can be detected in time, so that the transmission device 200 can be maintained in time to prevent further damage.

[0071] The transmission device 200 provided in this embodiment includes several groups of rolling components 210 arranged side by side, including a first driving roller 211, a second driving roller 212, a driven roller 213, and a support wire 214. One end of the support wire 214 is fixed to the first driving roller 211, the middle section is wrapped around the driven roller 213, and the other end is fixed to the second driving roller 212. The support wire 214 has redundant sections, which are initially wrapped around the first driving roller 211 and / or the second driving roller 212. Because the support wire 214 serves as a supporting platform for the object to be cured 20, the object to be cured 20 will not adhere to the transmission device 200 and can be smoothly transmitted. In addition, the transmission device 200 uses the support wire 214 as a supporting platform for the object to be cured 20, which can minimize the obstruction of light from below, thereby improving the efficiency of secondary curing.

[0072] Example 2

[0073] Figure 6 is a schematic diagram of the structure of a 3D printing secondary curing furnace according to an embodiment of the present invention, and Figure 7 is a simplified schematic diagram of the structure of a 3D printing secondary curing furnace according to an embodiment of the present invention. The structure of the 3D printing secondary curing furnace 10 according to this embodiment is described in conjunction with Figures 1 and 2. The structure primarily comprises a furnace body 100 having an inlet 110 and an outlet 120, and a transmission device. The transmission device 200 shown may be the transmission device 200 shown in the first embodiment. One end (T1) of the transmission device 200 is adjacent to the inlet 110, and the other end (T2) is adjacent to the outlet 120.

[0074] When the 3D printing secondary curing furnace 10 is working, one end of the transmission device 200 is close to the inlet 110 and the other end is close to the outlet 120 , and the object 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 light detector 300 is disposed above the support line 214 inside the furnace body 100 and / or a second light detector 400 is disposed below the support line 214 .

[0076] In this embodiment, the first light detector 300 is used to detect whether the object to be cured 20 has fallen or other abnormal conditions have occurred on the support line 214 when the object to be cured 20 is being transported to the secondary curing furnace, and the second light detector 400 is used to detect whether the object to be cured 20 has fallen under the support line 214. For example, the first light detector 300 is provided above the transport device 200. When the transport device 200 starts operating, the first driving wheel 211 is in the line-reeling state, and the second driving wheel 212 is in the line-defending state, driving the object to be cured 20 to move toward the exit 120 of the secondary curing furnace. When the curing operation is completed, the second driving wheel 212 is in the line-releasing state, and the first driving wheel 211 is in the line-reeling state. The support line 214 retracts during the process of the second light detector, and the second light detector detects whether there is any missing product on the support line 214.

[0077] Other details of the transmission device 200 in this embodiment can be referred to the aforementioned embodiment and will not be elaborated here.

[0078] The 3D printing secondary curing furnace 10 provided in this embodiment has a transmission device 200 having several groups 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 wire 214. One end of the support wire 214 is fixed to the first active roller 211, the middle section is wound around the driven roller 213, and the other end is fixed to the second active roller 212. The support wire 214 has a redundant section, which is initially wound around the first active roller 211 and / or the second active roller 212. Because the support wire 214 serves as a supporting platform for the object to be cured 20, the object to be cured 20 will not adhere to the transmission device 200 and can be smoothly transported. Moreover, the transmission device 200 uses the support wire 214 as a supporting platform for the object to be cured 20, which can minimize the obstruction of light from below, thereby improving the efficiency of secondary curing.

[0079] Example 3

[0080] Figure 8 is a flow chart of a control method for a 3D printing secondary curing furnace according to an embodiment of the present invention. Referring to Figure 8, method 800 can be applied to the secondary curing furnace shown in the second embodiment, but is not limited thereto, and includes: S810, monitoring whether the transmission device is operating normally; when the transmission device is operating normally, starting the transmission device to bring the object to be cured into the secondary curing furnace; S820, closing the furnace door of the secondary curing furnace and filling the secondary curing furnace with inert gas; S830, turning on the light source of the secondary curing furnace when the inert gas is injected to a preset pressure; S840, starting to release the pressure after the preset curing time is completed, and opening the furnace door when the pressure is balanced to send the product on the transmission device away.

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

[0082] It can be understood that the entire curing process of the secondary curing furnace 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 the various execution nodes controlled by software or programs, that is, the operation process, and the working process is the continuous process between the nodes, such as transmission, heating, light curing, etc. Compared with the operation process, although the working process is not directly controlled by software or programs, it is also part of the secondary curing process of this embodiment. Those skilled in the art can understand that the method 800 of this embodiment essentially includes the entire process (operation process and working process).

[0083] For example, the control program or software of the method 800 of this embodiment can be written in C language, but is not limited to this language. Different programming languages ​​have no necessary connection between the implementation of the method 800 and the operating efficiency of the secondary curing furnace.

[0084] In one example, in the step of monitoring whether the conveying device operates normally, if it is detected that the conveying device operates abnormally, the secondary curing oven is stopped and / or an alarm is issued.

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

[0086] The self-test process checks all functions of the post-curing oven, including the control system and heating system, to ensure that the oven is in a safe state before normal operation. During the self-test process, faults can also be diagnosed and located, allowing potential problems to be discovered and resolved promptly, preventing malfunctions during operation that could affect production efficiency and product quality.

[0087] In one example, method 800 further includes detecting whether there are any unsuccessfully removed products on the conveyor during the process of removing the products from the conveyor. This detection process is typically implemented by a light detector. For example, if cured products are detected on the conveyor during the resetting process of the conveyor, this indicates that some products were not successfully removed during the product transfer process. In such cases, timely maintenance of the secondary curing oven is required to prevent any dropped products from damaging the secondary curing oven.

[0088] The control method of the 3D printing secondary curing furnace provided in this embodiment uses an improved transmission device, so the object to be cured will not adhere to the transmission device and can be smoothly transmitted out. In addition, the transmission device uses a support line as a supporting platform for the object to be cured, which can avoid blocking the lower light to the greatest extent, thereby improving the efficiency of secondary curing.

[0089] Example 4

[0090] Figure 9 is a structural schematic diagram of a control device for a 3D printing secondary curing furnace according to an embodiment of the present invention. Referring to Figure 9, the device 900 mainly includes: a starting module 901, which is used to monitor whether the transmission device is operating normally; when the transmission device is operating normally, the transmission device is started to bring the object to be cured into the secondary curing furnace; a charging module 902, which is used to close the furnace door of the secondary curing furnace and fill the secondary curing furnace with inert gas; a light starting module 903, which is used to turn on the light source of the secondary curing furnace when the inert gas is injected to a preset pressure; an ending module 904, which is used to turn on the light source of the secondary curing furnace when the inert gas is injected to a preset pressure; and an ending module 905, which is used to start depressurizing after the preset curing time is completed, and open the furnace door until the pressure is balanced to send the product on the transmission device away.

[0091] In one example, the device 900 may further include a first protection module for stopping the secondary curing furnace and / or issuing an alarm if abnormal operation of the transmission device is detected during the process of monitoring whether the transmission device is operating normally.

[0092] In one example, the apparatus 900 may further include a self-test module for controlling the secondary curing oven to perform a power-on self-test.

[0093] In one example, the device 900 may further include a detection module for detecting whether there are any products on the transport device that have not been successfully transported away during the process of transporting the products on the transport device.

[0094] In one example, the device 900 further includes a second protection module, configured to stop the secondary curing oven and / or issue an alarm if it is detected that there are products on the conveying device that have not been successfully transported away.
