Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a three-dimensional forming device. Background Art

[0002] A three-dimensional forming device is a cumulative manufacturing technology and a machine of rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metals, plastics and other bondable materials to manufacture three-dimensional objects by sequentially printing multiple layers of bondable materials.

[0003] Among them, a stereolithography apparatus adopts stereolithography printing technology. Stereolithography uses photosensitive resin as raw material, and light with a specific wavelength and intensity is focused on the surface of the photocuring material, so that it solidifies from point to line and from line to surface in sequence to complete the curing of one layer. Then, the forming platform is driven by a lifting mechanism to move a layer height in the vertical direction, and another layer is cured. Layers are sequentially stacked on the forming platform to form a three-dimensional entity.

[0004] In the related art three-dimensional forming device, after the model printing is completed, the printing platform is suspended on the support component in the printing posture. Since the photocuring resin is relatively viscous and has poor fluidity, the resin adhered to the printing platform and the model will not completely flow back into the material tank. In this way, during the operation of taking the model, the resin adhered to the printing platform and the model surface will drip onto the surface of the machine and the desktop, which is difficult to clean, and the use experience is relatively poor.

Detailed implementation manners

[0046] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0047] Refer to the following Figures 1 to 16 to describe a stereolithography apparatus 100 provided according to some embodiments of the present utility model. The stereolithography apparatus 100 may be a digital light processing 3D printer.

[0048] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 12 , Figure 13 , Figure 14 A stereolithography apparatus 100 provided by the present utility model includes a lifting mechanism 110, a printing platform 120, and a support assembly 130. The support assembly 130 includes a support frame 131 and a carrier 132 connected to each other. The support frame 131 is connected to the lifting mechanism 110, and the printing platform 120 is detachably connected to the carrier 132. Among them, the support assembly 130 further includes an attitude adjustment assembly connected to the support frame 131 and / or the carrier 132. The attitude adjustment assembly includes a hanging structure 133 and / or an adjustment mechanism 134. The printing platform 120 is detachably connected to the hanging structure 133 in an inclined attitude, and the adjustment mechanism 134 is used to drive the carrier 132 to rotate relative to the support frame 131 to adjust the attitude of the printing platform 120.

[0049] Among them, as shown in Figure 1 and Figure 2 , the stereolithography apparatus 100 further includes a base 150 and a material tank 140. The lifting mechanism 110 is connected to the base 150 and is movable relative to the base 150 in the vertical direction. The vertical direction may be as shown by the arrow Z in Figure 1 and Figure 2 . The material tank 140 is placed on the base 150, and the material tank 140 is used to accommodate resin. Specifically, the material tank 140 may be placed on the top of the base 150. The printing platform 120 is connected to the lifting mechanism 110 through the support assembly 130 and is located above the material tank 140. The printing platform 120 moves in the vertical direction along with the lifting mechanism 110 to approach or move away from the material tank 140. Among them, the stereolithography apparatus 100 further includes a light source assembly. The light source assembly is located inside the base 150 for emitting curing light. Thus, by using the stereolithography technology, light with a specific wavelength and intensity is focused on the resin in the material tank 140, so that the resin solidifies on the printing platform 120. After one layer is cured, the printing platform 120 moves away from the material tank 140 by the height of one layer along with the lifting module, and then another layer is cured, and the layers are sequentially stacked on the printing platform 120 to form a three-dimensional entity.

[0050] The support component 130 provided in this embodiment includes a support frame 131, a carrier 132, and an attitude adjustment component. Among them, the support frame 131 is connected to the carrier 132, and the printing platform 120 is detachably connected to the carrier 132. Thus, by connecting the support frame 131 to the lifting mechanism 110, the printing platform 120 can be indirectly connected to the lifting mechanism 110, enabling the printing platform 120 to move synchronously with the lifting mechanism 110 in the vertical direction, thereby meeting the requirements of stereolithography printing. It can be understood that, as Figure 1 shown, when the printing platform 120 is connected to the lifting mechanism 110 through the support component 130 and is in the printing attitude, the forming surface of the printing platform 120 is parallel to the material tank 140, or it can be understood that the forming surface of the printing platform 120 is parallel to the horizontal plane, thereby ensuring good printing quality. As Figure 2 shown, after the model 200 is printed, the attitude of the printing platform 120 is adjusted through the attitude adjustment component. For example, the printing platform 120 is connected to the hanging structure 133 of the attitude adjustment component in an inclined attitude, and / or the adjustment mechanism 134 in the attitude adjustment component drives the carrier 132 to rotate relative to the support frame 131 to adjust the attitude of the printing platform 120 to make the printing platform 120 inclined, which can enable the residual resin on the printing platform 120 and the model 200 to flow back into the material tank 140 under the drainage of the inclined printing platform 120, avoiding the problem that the residual resin on the printing platform 120 and the model 200 drips onto the surface of the stereolithography device 100 and the surrounding environment of the stereolithography device 100 during the process of taking the model 200, avoiding resin contamination of the surface of the stereolithography device 100 and the surrounding environment of the stereolithography device 100, reducing the operation of cleaning the resin, enhancing the user experience. At the same time, it can avoid the problem that the residual resin on the printing platform 120 and the model 200 drips into the device during the process of taking the model 200 and corrodes the internal components, which is beneficial to extending the service life of the internal components of the device and improving the overall reliability of the stereolithography device 100.

[0051] Among them, as Figure 3 and Figure 4 shown, the attitude adjustment component can include a hanging structure 133, or, as Figures 5 to 7 shown, the attitude adjustment component can include an adjustment mechanism 134, or the attitude adjustment component can include a hanging structure 133 and an adjustment mechanism 134. Thus, it can meet the requirements of different structures of the support component 130 and has a wide range of applications.

[0052] Among them, the printing platform 120 is detachably connected to the bearing platform 132, which facilitates the disassembly and assembly of the printing platform 120 and the bearing platform 132, thereby facilitating the mold removal operation, and facilitating the disassembly of the printing platform 120 and the bearing platform 132 for maintenance or cleaning, improving the maintenance experience and cleaning experience of the printing platform 120. At the same time, the printing platform 120 is detachably connected to the bearing platform 132. When the attitude adjustment assembly includes the hanging structure 133, after the model 200 is printed, the printing platform 120 can be detached from the bearing platform 132 and connected to the hanging structure 133 in an inclined attitude, so that the remaining resin drops on the printing platform 120 and the model 200 fall into the material tank 140. Since the printing platform 120 is detachably connected to the hanging structure 133, it is convenient for the disassembly and assembly of the printing platform 120 and the hanging structure 133, thereby facilitating the mold removal operation, and facilitating the disassembly of the printing platform 120 and the hanging structure 133 and then connecting them to the bearing platform 132 or performing operations such as maintenance and cleaning.

[0053] Specifically, the printing platform 120 and the bearing platform 132 can be detachably connected by at least one of a bolt structure, a clamping structure, a mortise and tenon structure, a plugging structure, and a magnetic attraction structure. The printing platform 120 and the hanging structure 133 can be detachably connected by at least one of lapping, hooking, clamping, and plugging.

[0054] Among them, the attitude adjustment assembly can be connected to one of the support frame 131 and the bearing platform 132, or the attitude adjustment assembly can be connected to both the support frame 131 and the bearing platform 132 at the same time. For example, the hanging structure 133 can be connected to one of the support frame 131 and the bearing platform 132, or the hanging structure 133 can be connected to both the support frame 131 and the bearing platform 132 at the same time, or the adjusting mechanism 134 can be connected to one of the support frame 131 and the bearing platform 132, or the adjusting mechanism 134 can be connected to both the support frame 131 and the bearing platform 132 at the same time. It can be understood that the connection here can be understood as a broad connection, such as direct connection, indirect connection, connection achieved through installation, connection achieved through integral molding, etc.

[0055] Among them, as Figure 2 and Figure 4 shown, the printing platform 120 is in an inclined attitude, which can be understood as that the forming surface of the printing platform 120 is inclined with respect to the horizontal plane.

[0056] In some possible embodiments provided by the present invention, the hanging structure 133 is installed on or formed on the support frame 131 and / or the bearing platform 132.

[0057] In some examples, the hanging structure 133 is a split structure from the support frame 131 and the bearing platform 132. At this time, the hanging structure 133 can be installed on the support frame 131, or the hanging structure 133 can be installed on the bearing platform 132, or the hanging structure 133 can be installed on both the support frame 131 and the bearing platform 132. Specifically, the hanging structure 133 can be installed on the support frame 131 and / or the bearing platform 132 by means of a threaded structure, a clamping structure, a plugging structure, a mortise and tenon structure, a magnetic attraction structure, welding, bonding, etc.

[0058] In some other examples, the hanging structure 133 can be an integral structure with the support frame 131, or the hanging structure 133 can be an integral structure with the bearing platform 132. Thus, the steps of installing the hanging structure 133 and the support frame 131 are simplified, and the steps of installing the hanging structure 133 and the bearing platform 132 are simplified, which is suitable for mass production, helps to improve the production efficiency of the support assembly 130, and reduces the manufacturing cost of the support assembly 130. At the same time, this setting helps to improve the reliability and stability of the connection between the hanging structure 133 and the support frame 131, and the reliability and stability of the connection between the hanging structure 133 and the bearing platform 132.

[0059] In some possible embodiments provided by the present invention, the hanging structure 133 includes one or at least two hooks. By contacting and hanging the printing platform 120 with different numbers of hooks, the printing platform 120 can be connected to the hanging structure 133 in an inclined posture. Among them, different numbers of hooks of the hanging structure 133 can meet the requirements of different structures and different arrangement methods of the hooks.

[0060] In some possible embodiments provided by the present invention, the hanging structure 133 includes one hook. One hook is provided with a contact surface that contacts the printing platform 120, and the contact surface is arranged obliquely with respect to the horizontal plane. Thus, when the printing platform 120 contacts and hangs on the contact surface, the printing platform 120 can be hung on the hook in an inclined posture, so that the residual resin on the printing platform 120 and the model 200 flows back into the material tank 140 under the drainage of the printing platform 120 in the inclined posture, avoiding the problem that the residual resin drips onto the surface of the stereolithography apparatus 100, the peripheral environment of the stereolithography apparatus 100, and the inside of the apparatus during the process of taking the model 200, which is beneficial to improving the user experience and the overall reliability of the stereolithography apparatus 100.

[0061] In some embodiments, the contact surface at least includes a first contact surface arranged upward, and the first contact surface is one or more. The first contact surface is a plane or a curved surface; or, when there are multiple first contact surfaces, the multiple first contact surfaces are arranged in a stepped manner.

[0062] In some embodiments, the contact surface further includes a second contact surface disposed downward, and the second contact surface is one or more, and the second contact surface is a plane or a curved surface; or, in the case where there are multiple second contact surfaces, the multiple second contact surfaces are arranged in a stepped manner.

[0063] As Figure 6 and Figure 7 shown, in some possible embodiments provided by the present utility model, the contact surface at least includes a first contact surface 1336 disposed upward. Thus, the printing platform 120 is in contact with the first contact surface 1336 with the hook disposed upward. In this way, under the action of the self-gravity of the printing platform 120, the printing platform 120 can be suspended on the hook in an inclined posture. It can be understood that the first contact surface 1336 is also inclined.

[0064] Among them, the first contact surface 1336 is a plurality of planes, and the plurality of planes are arranged in a stepped manner. Specifically, the plurality of planes can be parallel or non-parallel. The stepped plurality of planes enable at least two surfaces to be in contact with the printing platform 120, and there is a height difference between two adjacent surfaces. Thus, on the basis of realizing the support and suspension of the printing platform 120 by the stepped planes, the stepped planes can also be used to limit the movement of the printing platform 120 relative to the hook.

[0065] Specifically, as Figure 7 shown, the first contact surface 1336 is a plurality of planes arranged in a stepped manner. Among them, the plane facing the opening side of the hook among the plurality of planes is higher than the plane far from the opening side. Thus, the higher plane facing the opening side of the hook among the stepped plurality of planes can prevent the part of the printing platform 120 in contact with other planes from moving toward the opening side of the hook. Thus, the reliability and stability of the contact between the printing platform 120 and the first contact surface 1336 can be improved, and the reliability and stability of the support and suspension of the hook and the printing platform 120 can be improved, so that the printing platform 120 can be stably suspended on the hook in an inclined posture.

[0066] As Figure 7 shown, in the above embodiment, the contact surface further includes a second contact surface 1337 disposed downward. Thus, by cooperating with the first contact surface 1336 and the second contact surface 1337, the movement of the printing platform 120 relative to the hook can be limited from the upper and lower directions, which can further improve the reliability and stability of the printing platform 120 supported and suspended on the hook, reduce or avoid the situation that the printing platform 120 turns over due to the overweight of the items on the printing platform 120, and can prevent the printing platform 120 from falling, so that the printing platform 120 can be stably suspended on the hook in an inclined posture. It can be understood that the second contact surface 1337 is also inclined.

[0067] Specifically, the second contact surface 1337 is a plane or multiple planes arranged in a stepped manner. Among them, the multiple planes arranged in a stepped manner enable at least two surfaces to contact the printing platform 120, and there is a height difference between two adjacent surfaces. Thus, on the basis of realizing the support and suspension of the printing platform 120 by using the multiple planes arranged in a stepped manner, the multiple planes arranged in a stepped manner can also limit the movement of the printing platform 120 relative to the hook.

[0068] Specifically, one of the first contact surface 1336 and the second contact surface 1337 is a plane, and the other is multiple planes arranged in a stepped manner. As Figure 7 shown, the first contact surface 1336 is multiple planes arranged in a stepped manner, and the second contact surface 1337 is a plane, or the first contact surface 1336 is a plane, and the second contact surface 1337 is multiple planes arranged in a stepped manner. By limiting the movement of the printing platform 120 relative to the hook from the upper and lower directions through the plane and the multiple planes arranged in a stepped manner, the reliability and stability of the printing platform 120 supported and suspended on the hook can be greatly improved, the situation that the printing platform 120 turns over due to the overweight of the items on the printing platform 120 can be reduced or avoided, and the printing platform 120 can be prevented from falling. As Figure 3 and Figure 4 shown, in some possible implementation embodiments provided by the present invention, the hanging structure 133 includes at least two hooks. The hook includes a first arm 1333 in contact with the printing platform 120. The first arms 1333 of at least two hooks are arranged in sequence along a first direction, and the first direction is arranged obliquely relative to the horizontal plane. Among them, the first direction can be as Figure 3 shown by the arrow P in Figure 3 , and the vertical direction can be as

[0069] shown by the arrow Z in

[0070] shown. The horizontal plane can be understood as a plane perpendicular to Z. Figure 3 and Figure 4As shown, the number of hooks is two, including a first hook 1331 and a second hook 1332. The two hooks can provide two-point support for the printing platform 120, enabling the printing platform 120 to reliably and stably contact and hang on the two hooks.

[0071] As Figure 3 and Figure 4 shown, in some possible embodiments provided by the present utility model, the hook further includes a second arm 1334 connected to the first arm 1333. The first end of the second arm 1334 is connected to the first arm 1333, and the second end of the second arm 1334 is connected to the support frame 131 and / or the bearing table 132.

[0072] That is to say, the hook is connected to the support frame 131 and / or the bearing table 132 through the second arm 1334, and the first arm 1333 of the hook is used to contact and hang the printing platform 120. It can be understood that, however, the hook can be connected to the support frame 131 and / or the bearing table 132 by means of installation or integrally formed.

[0073] In some examples, the dimensions of the second arms 1334 of at least two hooks increase or decrease in sequence in the vertical direction.

[0074] That is to say, the lengths of the second arms 1334 of each hook in this example are not equal. The length of the second arm 1334 can be understood as the dimension of the second arm 1334 along the vertical direction. Since the first ends of the second arms 1334 of each hook are connected to the support frame 131 and / or the bearing table 132, it can be understood that the first ends of the second arms 1334 of each hook are located in the same plane parallel to the horizontal plane. By making the dimensions of the second arms 1334 of at least two hooks increase or decrease in sequence in the vertical direction, the positions of the second ends of the second arms 1334 of at least two hooks in the vertical direction are different, and the second ends of the second arms 1334 of at least two hooks rise or fall in sequence in the vertical direction. Thus, the positions of the first arms 1333 connected to the second ends of the second arms 1334 in the vertical direction are different, so that the first arms 1333 of at least two hooks can be arranged in sequence along a first direction inclined relative to the horizontal plane, so that the printing platform 120 can contact and hang on at least two hooks in an inclined posture.

[0075] Specifically as Figure 3 shown, the vertical direction is as Figure 3As shown by the arrow Z therein. The vertical dimension of the second arm 1334 of the first hook 1331 is smaller than the vertical dimension of the second arm 1334 of the second hook 1332, such that in the vertical direction, the first arm 1333 of the first hook 1331 is located above the first arm 1333 of the second hook 1332, so that the first arms 1333 of the two hooks are arranged in sequence along a first direction inclined relative to the horizontal plane. Thus, it can be ensured that the printing platform 120 can contact and hang on the two hooks in an inclined posture, with a simple structure and convenient operation.

[0076] In some other examples, the vertical dimensions of the second arms 1334 of at least two hooks are equal, and the positions where the support frame 131 and / or the bearing platform 132 are connected to the first ends of the second arms 1334 increase or decrease in sequence in the vertical direction.

[0077] That is to say, in this example, the lengths of the second arms 1334 of each hook are equal, that is, the vertical dimensions of the second arms 1334 of each hook are equal. By setting the positions where the support frame 131 and / or the bearing platform 132 are connected to the first ends of the second arms 1334 to increase or decrease in sequence in the vertical direction, the positions of the first ends of the second arms 1334 of each hook in the vertical direction are different, that is, the first ends of the second arms 1334 of at least two hooks rise or fall in sequence in the vertical direction. Since the lengths of the second arms 1334 of each hook are equal, the positions of the first arms 1333 connected to the second ends of the second arms 1334 in the vertical direction are different, so that the first arms 1333 of at least two hooks can be arranged in sequence along a first direction inclined relative to the horizontal plane, so that the printing platform 120 can contact and hang on at least two hooks in an inclined posture.

[0078] Such as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown in

[0079] In this embodiment, since the positioning portion 1335 is located above the first support arm 1333, and the first support arm 1333 is in contact with the printing platform 120, when the positioning portion 1335 is in contact with the printing platform 120, the positioning portion 1335 cooperates with the first support arm 1333 to contact the printing platform 120 from the upper and lower directions. Furthermore, it can prevent the phenomenon that the printing platform 120 turns outward due to the excessive weight of the formed article, and can prevent the printing platform 120 from accidentally falling, so that the printing platform 120 can be reliably and relatively stably suspended on the hook in an inclined posture.

[0080] As Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, in the above embodiment, the height difference between the surfaces of the first support arms 1333 of two adjacent hooks in contact with the printing platform 120 is equal to the height difference between the surfaces of the positioning portions 1335 in contact with the printing platform 120.

[0081] Among them, the height difference between the surfaces of the first support arms 1333 of two adjacent hooks in contact with the printing platform 120 can be as shown by D1 in Figure 9 and Figure 11 , and the height difference between the surfaces of the positioning portions 1335 of two adjacent hooks in contact with the printing platform 120 can be as shown by D2 in Figure 9 , that is, D1 is equal to D2.

[0082] Among them, the contact surface between the first support arm 1333 and the printing platform 120 can be understood as the first contact surface 1336 of the hook, and the contact surface between the positioning portion 1335 and the printing platform 120 can be understood as the second contact surface 1337 of the hook. That is to say, the height difference between the first contact surfaces 1336 of the first support arms 1333 of two adjacent hooks is equal to the height difference between the second contact surfaces 1337 of the positioning portions 1335 of two adjacent hooks. Thus, it can reduce the possibility that the printing platform 120 shakes between multiple hooks or the printing platform 120 rotates relative to the hook directly, avoid or reduce the problem that the resin sprays onto other parts of the printing device or the workbench due to the shaking of the printing platform 120 and is difficult to clean. At the same time, it can avoid the problem that the printing platform 120 shakes between multiple hooks and increases the wear on the hook, making the hook prone to failure, which is beneficial to improving the user's satisfaction and the reliability of the printing device.

[0083] As Figure 5As shown, in some possible embodiments provided by the present utility model, the printing platform 120 is provided with a mating portion 1223 that contacts the hook, and the mating portion 1223 is provided as a groove structure or a through-hole structure. The setting of the mating portion 1223 is conducive to improving the reliability and stability of the contact and suspension between the hook and the printing platform 120. At the same time, the mating portion 1223 cooperates with the portion on the hook that contacts the printing platform 120, which can achieve the pre-positioning function of the printing platform 120 and the hook, and thus facilitate the handling operation of the printing platform 120 and the hook.

[0084] Among them, the mating portion 1223 is a groove structure or a through-hole structure, which is convenient for processing and easy to implement.

[0085] Such as Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 As shown, in some possible embodiments provided by the present utility model, the adjusting mechanism 134 is respectively connected to the support frame 131 and the bearing platform 132. That is, the adjusting mechanism 134 can be connected between the support frame 131 and the bearing platform 132. Thus, the bearing platform 132 can be driven to rotate relative to the support frame 131 through the adjusting mechanism 134 to adjust the posture of the printing platform 120, so that the forming surface of the printing platform 120 is adjusted from parallel to the horizontal plane to inclined to the horizontal plane, so that the residual resin on the printing platform 120 and the model 200 flows back into the material tank 140 under the drainage of the inclined printing platform 120, avoiding the problem that the residual resin drips onto the surface of the stereolithography apparatus 100, the surrounding environment of the stereolithography apparatus 100, and the inside of the base 150 during the process of taking the model 200, which is beneficial to improving the user experience and the overall reliability of the stereolithography apparatus 100.

[0086] Among them, as Figure 15 and Figure 16 shown, the adjusting mechanism 134 includes a gear mechanism 1341. The gear mechanism 1341 has an accurate transmission ratio, and has the advantages of high transmission efficiency, compact structure, reliable operation, and long service life. Thus, it can meet the design requirements of the support assembly 130 with a compact structure and a small volume. At the same time, it is beneficial to improve the reliability of the support assembly 130, and further improve the reliability of the whole machine.

[0087] Such as Figure 15 and Figure 16As shown, in some possible embodiments provided by the present utility model, the adjusting mechanism 134 further includes a driving member 1344 connected to the gear mechanism 1341. The driving member 1344 and the gear mechanism 1341 are accommodated in the installation groove 1311 opened in the support frame 131. Thus, the installation groove 1311 of the support frame 131 provides an installation space for the driving member 1344 and the gear mechanism 1341, and plays a good protective role for the driving member 1344 and the gear mechanism 1341, which can reduce the pollution of the resin to the driving member 1344 and the gear mechanism 1341. At the same time, since the temperature of the space where the printing platform 120 is located is relatively high during the light curing process, in this embodiment, the driving member 1344 and the gear mechanism 1341 are accommodated in the installation groove 1311, which can reduce the influence of the high temperature of the space where the printing platform 120 is located on the driving member 1344 and the gear mechanism 1341, is beneficial to improving the service life of the driving member 1344 and the gear mechanism 1341, and further extends the reliability of the support assembly 130 and improves the reliability of the whole machine.

[0088] As Figure 15 and Figure 16 As shown, in some possible embodiments provided by the present utility model, the gear mechanism 1341 includes a first gear 1342 and a second gear 1343 which are drivingly connected. The first gear 1342 is connected to the output shaft of the driving member 1344, and the second gear 1343 is installed on or formed on the bearing platform 132.

[0089] Thus, when the driving member 1344 works, it drives the first gear 1342 to rotate through the output shaft, and drives the second gear 1343 to rotate through the first gear 1342. Since the second gear 1343 is installed on or formed on the bearing platform 132, it can drive the bearing platform 132 to rotate relative to the support frame 131, so that the printing platform 120 connected to the bearing platform 132 rotates relative to the support frame 131, and the forming surface of the printing platform 120 is adjusted from being parallel to the horizontal plane to being inclined to the horizontal plane. It can be understood that the first gear 1342 and the second gear 1343 are drivingly connected, which can be that the first gear 1342 and the second gear 1343 are directly meshed, or the first gear 1342 and the second gear 1343 are indirectly meshed, such as there are other gears between the first gear 1342 and the second gear 1343.

[0090] In some examples, the second gear 1343 and the bearing platform 132 are of a split structure, and the second gear 1343 is installed on the bearing platform 132. In this way, it is convenient to disassemble and separate the second gear 1343 from the bearing platform 132 for maintenance or replacement of parts, which is beneficial to improving the maintenance efficiency of the second gear 1343 and reducing the replacement cost. Specifically, the second gear 1343 can be connected to the bearing platform 132 by at least one of a bolt structure, a clamping structure, a plugging structure, a mortise and tenon structure, welding, and bonding.

[0091] As Figure 16 shown, in some other examples, the second gear 1343 and the carrier 132 are of an integral structure, and the second gear 1343 is formed on the carrier 132. In this way, the setting of the connection structure between the second gear 1343 and the carrier 132 can be simplified, the assembly steps of the second gear 1343 and the carrier 132 can be simplified, the production efficiency of the support assembly 130 can be improved, the manufacturing cost can be reduced. At the same time, the design requirements of the support assembly 130 with a compact structure and a small volume can be met, and it is beneficial to improve the reliability and stability of the connection between the second gear 1343 and the carrier 132.

[0092] As Figure 15 and Figure 16 shown, in some possible embodiments provided by the present utility model, the carrier 132 is provided with a connection portion 1321 for connecting with the printing platform 120. The carrier 132 includes a bearing section 1322 and a connection section 1323. The connection portion 1321 is arranged on the bearing section 1322. The connection section 1323 is rotatably connected with the support frame 131 and is located in the installation groove 1311. The second gear 1343 is installed on or formed on the connection section 1323.

[0093] In this embodiment, the carrier 132 includes a bearing section 1322 and a connection section 1323. The detachable connection with the printing platform 120 can be realized through the connection portion 1321 on the bearing section 1322. By installing or forming the second gear 1343 on the connection section 1323, the carrier 132 can be connected with the driving member through the first gear 1342, so that the driving member 1344 installed on the support frame 131 works. Through the gear mechanism 1341, the carrier 132 can be driven to rotate relative to the support frame 131 to adjust the posture of the printing platform 120.

[0094] Among them, the connection section 1323 is located in the installation groove 1311, so that the installation groove 1311 plays a good protective role for the second gear 1343 installed on the connection section 1323 or formed on the connection section 1323, which can reduce the pollution of the resin to the second gear 1343. At the same time, it can reduce the influence of the high temperature in the space where the printing platform 120 is located on the second gear 1343, which is beneficial to improve the service life of the second gear 1343, and further extend the reliability of the support assembly 130 and improve the reliability of the whole machine.

[0095] Specifically, the second gear 1343 is installed at the end of the connection section 1323 far from the bearing section 1322, or the second gear 1343 is formed at the end of the connection portion 1321 far from the bearing portion.

[0096] As Figure 14 、 Figure 15 andFigure 16 As shown, in some possible embodiments provided by the present utility model, the support frame 131 includes a support base 1312 and a connection base 1313. The connection base 1313 is located between the support base 1312 and the carrier table 132 and connects the support base 1312 and the carrier table 132. The installation groove 1311 includes a groove 1314 formed in the support base 1312 and a through groove 1315 formed in the connection base 1313. At least part of the driving member is installed in the groove 1314, and the gear mechanism 1341 and the connection section 1323 are located in the through groove 1315.

[0097] In this embodiment, the support frame 131 is set as a split support base 1312 and connection base 1313. The connection base 1313 connects the support base 1312 and the carrier table 132. The groove 1314 on the support base 1312 and the through groove 1315 on the connection base 1313 enclose the installation groove 1311. The driving member is installed in the groove 1314, and the gear mechanism 1341 and the connection section 1323 are located in the through groove 1315. With this arrangement, while ensuring that the installation groove 1311 can provide good and comprehensive protection for the driving member 1344 and the gear mechanism 1341, it is convenient for the assembly and disassembly of the driving member 1344, the gear mechanism 1341, the support frame 131 and the carrier table 132, which is beneficial to improving the production efficiency and maintenance efficiency of the entire support assembly 130.

[0098] Specifically, the support base 1312 and the connection base 1313, and the connection base 1313 and the carrier table 132 can be detachably connected by at least one of a bolt structure, a plug-in structure, a snap-fit structure, a mortise and tenon structure, and a magnetic attraction structure.

[0099] Such as Figure 1 、 Figure 2 、 Figure 12 、 Figure 13 As shown, in some possible embodiments provided by the present utility model, the printing platform 120 includes a platform body 121 and a fixing base 122. The platform body 121 is connected to the bottom of the fixing base 122, and the fixing base 122 is detachably connected to the carrier table 132.

[0100] Among them, the platform body 121 is provided with a forming surface. It can be understood that when the printing platform 120 is in the printing posture, the forming surface faces the material tank 140 and is parallel to the horizontal plane.

[0101] In this embodiment, the platform body 121 is connected to the bottom of the fixing base 122, and the fixing base 122 and the bearing platform 132 are detachably connected, so that the platform body 121 can be connected to the bearing platform 132. The setting of the fixing base 122 can increase the distance between the platform body 121 and the bearing platform 132 in the vertical direction, reduce the possibility of the bearing platform 132 being contaminated by resin during printing, and improve the cleanliness of the bearing platform 132.

[0102] Among them, the platform body 121 and the fixing base 122 can be detachably connected by at least one of a bolt structure, a clamping structure, a plugging structure, a mortise and tenon structure, and a magnetic attraction structure.

[0103] Such as Figure 1 、 Figure 2 、 Figure 12 、 Figure 13 As shown, in some possible embodiments provided by the present utility model, the platform body 121 further includes a limiting member 123. The limiting member 123 connects the fixing base 122 and the bearing platform 132, and can limit the relative movement of the fixing base 122 and the bearing platform 132 to realize the connection between the fixing base 122 and the bearing platform 132, and further connect the printing platform 120 and the bearing platform 132. Specifically, the fixing base 122 and the bearing platform 132 can also be detachably connected by at least one of a clamping structure, a plugging structure, a mortise and tenon structure, and a magnetic attraction structure.

[0104] Such as Figure 4 、 Figure 12 、 Figure 13 As shown, optionally, the fixing base 122 is provided with a limiting groove with a lateral opening. The limiting groove is used to accommodate part of the bearing platform 132. A through hole 1221 is opened on the groove wall of the limiting groove far from the platform body 121. The limiting member 123 passes through the through hole 1221 and is connected to the bearing platform 132. For example, when the limiting member 123 passes through the through hole 1221 and is connected to the connection hole on the bearing platform 132, the relative movement of the fixing base 122 and the bearing platform 132 can be limited. For example, the limiting member 123 can lock and fix the fixing base 122 and the bearing platform 132, and further lock and fix the printing platform 120 and the bearing platform 132.

[0105] Specifically, the limiting member 123 is a bolt, and the connecting portion 1321 on the bearing platform 132 is a connecting hole. The bolt passes through the through hole 1221 of the fixing base 122 and is connected to the connecting hole on the bearing platform 132, so that the fixing base 122 and the bearing platform 132 can be locked and fixed. Among them, by matching the limiting groove with part of the fixing base 122, the installation pre-positioning of the fixing base 122 and the bearing platform 132 can be realized, which is beneficial to improving the assembly efficiency of the two.

[0106] Such as Figure 4As shown, in some possible embodiments provided by the present utility model, the groove wall of the limiting groove away from the platform body 121 is also used for contacting and hanging with the hanging structure 133. That is to say, the self-structure of the limiting groove can be utilized. For example, by using the groove wall at the top of the limiting groove, the contact and hanging between the fixing seat 122 and the hanging structure 133 on the supporting component 130 can be realized. Thus, the setting of the positioning part matching with the hanging structure 133 on the fixing seat 122 can be simplified, the structure is simple and easy to implement, which is beneficial to reducing the manufacturing cost.

[0107] In some other possible embodiments provided by the present utility model, a limiting part for contacting and hanging with the hanging structure 133 is arranged on the outer wall of the fixing seat 122. Thus, after the model 200 is printed, the limiting member 123 is used to release the limit between the fixing seat 122 and the bearing platform 132, separate the fixing seat 122 from the bearing platform 132, and contact and hang the fixing seat 122 on the hanging structure 133 of the supporting component 130 by using the limiting part on the fixing seat 122, so that the forming surface of the platform body 121 can be inclined relative to the horizontal plane, and the operation is simple and convenient.

[0108] Among them, the limiting part can be a positioning rib, a positioning plate, a buckle, a snap ring, etc. The limiting part can be a split structure with the fixing seat 122 and be installed on the fixing seat 122. Or, the limiting part can be an integrally formed structure with the fixing seat 122.

[0109] Optionally, the three-dimensional forming device 100 provided by the embodiment of the present utility model further includes a cover body 160. The cover body 160 is movably connected to the base 150. The cover body 160 and the base 150 are connected and can enclose a printing space. The lifting mechanism 110, the printing platform 120, and the material tank 140 are located in the printing space. The relative movement of the cover body 160 with respect to the base 150 can open the printing space to operate on the printing platform 120, the lifting mechanism 110, and the material tank 140, such as disassembling and separating the printing platform 120 from the supporting component 130, or repairing and replacing parts of the lifting mechanism 110, or replenishing materials to the material tank 140.
