Description

Technical Field

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

[0002] Stereoscopic molding equipment is a kind of cumulative manufacturing technology and a machine of rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metal or plastic and other adhesive materials to print multiple layers of adhesive materials in sequence to create three-dimensional objects.

[0003] Among them, the photocuring three-dimensional molding equipment adopts photocuring printing technology. Photocuring uses photosensitive resin as raw material, and focuses light of specific wavelength and intensity onto the surface of the photocuring material to solidify it from point to line, and from line to surface in sequence, completing the curing of one layer, and then driving the printing platform through the lifting mechanism to move the lifting module in the vertical direction to the height of a layer, and then solidify another layer, and stack them layer by layer on the printing platform to form a three-dimensional entity.

[0004] If the height of the lifting module is insufficient, it will affect the height of the printed model, thus limiting the printing range of the 3D molding equipment.

DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0042] Refer to the following Figures 1 to 14 The three-dimensional molding device 100 provided according to some embodiments of the present invention is described. The three-dimensional molding device 100 may be a light-curing three-dimensional printer.

[0043] like Figure 1 and Figure 8 As shown, the three-dimensional molding device 100 provided by the embodiment of the utility model comprises: a base 110, the base 110 comprises a top plate 111 and a bottom plate 112 arranged opposite to each other; a lifting module 120, connected to the base 110 and extending to the top of the top plate 111; a printing platform 170, the printing platform 170 is connected to the lifting module 20, and the lifting module 120 drives the printing platform 170 to rise and fall; a telescopic mechanism, arranged in the base 110, the telescopic mechanism comprises a first end and a second end which can be telescopically moved relative to each other, the first end being connected to the top plate 111, and the second end being connected to the bottom plate 112; the first end is connected to the base 110 relative to each other, and the second end is connected to at least a portion of the lifting module 120.

[0044] The extension direction of the lifting module 120 is as follows: Figure 1As shown in the arrow Z direction in FIG. 1 , it can be understood that the lifting module 120 extends in the vertical direction. The three-dimensional molding device 100 also includes a material trough 180 and a printing platform 170. The material trough 180 is used to contain resin. The material trough 180 is placed on the base 110. Specifically, the material trough 180 can be placed on the top plate 111 of the base 110. The printing platform 170 is movably connected to the lifting module 120 and is located above the material trough 180. The printing platform 170 can move along the lifting module 120 to approach or move away from the material trough 180. Among them, the three-dimensional molding equipment 100 also includes a light source component, which is located inside the base 110 and is used to emit curing light. Thus, by utilizing light curing technology, light of a specific wavelength and intensity is focused on the resin in the material tank 180, so that the resin is solidified on the printing platform 170. After completing the curing of one layer, the printing platform 170 is driven to move along the lifting module 120 in the direction away from the material tank 180 by the height of a layer, and then another layer is cured, and the layers are stacked one by one on the printing platform 170 to form a three-dimensional entity.

[0045] like Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, the stereoscopic molding device 100 provided in this embodiment further includes a telescopic mechanism, and the telescopic mechanism includes a first end and a second end that can be telescopically moved relative to each other. In one example, the first end of the telescopic mechanism is connected to the top plate 111, and the second end is connected to the bottom plate 112, that is, the telescopic mechanism is used to drive the top plate 111 to telescopically move in the vertical direction relative to the bottom plate 112, thereby driving the lifting module 120 to move synchronously with the top plate 111, so that during transportation, the top plate 111 is kept in a retracted state relative to the bottom plate 112 to reduce the overall volume of the stereoscopic molding device 100, reduce the space occupied by the device, and reduce transportation costs. Alternatively, during the process of the telescopic mechanism driving the top plate 111 to move in the vertical direction relative to the bottom plate 112, the height of the lifting module 120 remains unchanged. In this way, the telescopic mechanism drives the top plate 111 to move vertically downward relative to the bottom plate 112, so that the top plate 111 and the bottom plate 112 remain in a retracted state, which can increase the distance between the top plate 111 and the top of the lifting module 120, and then increase the height difference between the material trough 180 placed on the top plate 111 and the printing platform 170 on the lifting module 120, which can meet the printing needs of models with large height requirements, and expand the printing range without increasing the volume of the three-dimensional molding device 100 and the transportation cost. At the same time, in this example, when the top plate 111 and the bottom plate 112 remain in the retracted state, the space occupied by the base 110 can be reduced to a greater extent, and the length space projected by the light source component can be fully compressed to improve the molding quality. In addition, during transportation, the transportation cost can also be reduced to a certain extent.

[0046] In another example, the first end of the telescopic mechanism is connected to the base 110, and the second end is connected to at least part of the lifting module 120, that is, the telescopic mechanism is used to drive at least part of the lifting module 120 to move telescopically in the vertical direction relative to the bottom plate 112. Therefore, when the position of the top plate 111 remains unchanged, at least part of the lifting module 120 can be driven by the telescopic mechanism to move vertically upward relative to the top plate 111, so that at least part of the lifting module 120 remains in an extended state relative to the top plate 111, which can increase the distance between the top plate 111 and the top of the lifting module 120, and further increase the height difference between the material trough 180 placed on the top plate 111 and the printing platform 170 on the lifting module 120, which can meet the printing requirements of models with larger height requirements and expand the printing range. At the same time, during transportation, at least part of the lifting module 120 is driven by the telescopic mechanism to move vertically downward relative to the bottom plate 112, reducing the height difference between the top plate 111 and the top of the lifting module 120, so that the overall height of the three-dimensional molding device 100 is reduced, and the space occupied by the device is reduced, which is convenient for transportation and handling, so as to reduce transportation costs.

[0047] In another example, the telescopic mechanism may include a plurality of first ends and second ends arranged relatively to each other, wherein the first end of a portion of the telescopic mechanism is connected to the top plate 111, and the second end is connected to the bottom plate 112, and the first end of a portion of the telescopic mechanism is connected to the base 110, and the second end is connected to at least a portion of the lifting module 120, that is, the telescopic mechanism is used to drive the top plate 111 to telescopically move relative to the bottom plate 112 in the vertical direction, and at the same time, the telescopic mechanism is used to drive at least a portion of the lifting module 120 to telescopically move relative to the bottom plate 112 in the vertical direction, so that the top plate 111 can be driven relative to the bottom plate by the telescopic mechanism. 112 moves vertically downward, so that the top plate 111 remains in a retracted state relative to the bottom plate 112. At the same time, the telescopic mechanism drives at least part of the lifting module 120 to move vertically upward relative to the bottom plate 112, so that the lifting module 120 and the bottom plate 112 remain in an extended state, thereby greatly increasing the height difference between the top plate 111 and the top of the lifting module 120, and further increasing the height difference between the material trough 180 placed on the top plate 111 and the printing platform 170 on the lifting module 120, so that the three-dimensional molding device 100 can meet the printing needs of models with greater height requirements and expand the printing range. At the same time, when transportation is required, the top plate 111 and the bottom plate 112 continue to remain in a retracted state through the telescopic mechanism, and the lifting module 120 is driven by the telescopic mechanism to move vertically downward relative to the bottom plate 112, so that the lifting module 120 and the bottom plate 112 remain in a retracted state, so that the overall height and volume of the three-dimensional molding device 100 are reduced, and the space occupied by the device is greatly reduced, which is convenient for handling and transportation, so as to reduce transportation costs.

[0048] That is to say, the three-dimensional molding device 100 of the present invention can drive the top plate 111 to be telescopically movable in the vertical direction relative to the bottom plate 112 through the telescopic mechanism; and / or, can drive at least a part of the lifting module 120 to be telescopically movable in the vertical direction relative to the bottom plate 112 through the telescopic mechanism, so that the three-dimensional molding device 100 can take into account both the transportation cost and the printing range, without increasing the space occupied / transportation cost of the device, or reducing the space occupied / transportation cost of the device, so that the three-dimensional molding device 100 has a larger printing range, or, without changing the printing range, reduces the transportation cost, is suitable for promotion and application, and improves user experience.

[0049] In the above embodiment, the first end of the telescopic mechanism is connected to the base 110, and the second end is connected to at least a portion of the lifting module 120, wherein the first end of the telescopic mechanism is connected to the base 110, which can be understood as the first end of the telescopic mechanism is directly connected to the base 110, or the first end of the telescopic mechanism is connected to a portion of the lifting module 120 fixedly connected to the base 110.

[0050] Specifically, when the first end of the telescopic mechanism is connected to the base 110, the second end of the telescopic mechanism is connected to the lifting module 120, thereby, the telescopic movement of the entire lifting module 120 relative to the base 110 can be achieved through the relative telescopic movement of the first end and the second end.

[0051] When the first end of the telescopic mechanism is connected to the partial lifting module 120 fixedly connected to the base 110, the lifting module 120 itself can be a telescopic structure, that is, the lifting module 120 can also include a movable part that can perform relative telescopic movement with the part fixedly connected to the base 110, and the second end of the telescopic mechanism is connected to the movable part of the lifting module 120. Thus, through the relative telescopic movement of the first end and the second end, the telescopic movement of the movable part of the lifting module 120 relative to the part fixedly connected to the base 110 can be realized, thereby realizing the telescopic movement of the partial lifting module 120 relative to the base 110.

[0052] That is to say, the telescopic movement of the lifting module 120 can be that the lifting module 120 as a whole performs telescopic movement relative to the base 110, or the lifting module 120 is segmented and part of the lifting module 120 can perform telescopic movement relative to the base 110, thereby meeting the requirements of different structures of the lifting module 120.

[0053] Furthermore, the telescopic mechanism is located inside the base 110, so that the base 110 has a good protective effect on the telescopic mechanism, which can reduce the failure rate of the telescopic mechanism, improve the reliability of the telescopic mechanism, and thus improve the overall reliability of the three-dimensional molding device 100. At the same time, the telescopic mechanism located inside the base 110 can be installed using the original space of the base 110, which will not increase the volume of the three-dimensional molding device 100, thereby helping to save transportation costs.

[0054] like Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, in some possible embodiments provided by the present invention, the telescopic mechanism includes a first telescopic mechanism 130, the first end of the first telescopic mechanism 130 is fixedly connected to the top plate 111, the second end of the first telescopic mechanism 130 is fixedly connected to the bottom plate 112, and the relative telescopic movement of the first end and the second end of the first telescopic mechanism 130 includes at least a vertical component. Thus, the top plate 111 can be driven to telescopically move relative to the bottom plate 112 in the vertical direction by the first telescopic mechanism 130 to adjust the occupied space of the base 110, so that the three-dimensional molding device 100 can meet the printing requirements of models with a larger height, expand the printing range, and reduce the transportation cost, which is suitable for popularization and application.

[0055] The relative telescopic movement between the first end and the second end of the first telescopic mechanism 130 at least includes a component in the vertical direction. It can be understood that the relative telescopic movement between the first end and the second end of the first telescopic mechanism 130 is a telescopic movement in the vertical direction. In this way, the telescopic movement of the first end and the second end of the first telescopic mechanism 130 along the vertical direction can drive the top plate 111 to move in the vertical direction relative to the bottom plate 112. Alternatively, the relative telescopic movement between the first end and the second end of the first telescopic mechanism 130 is inclined to the vertical direction, so that the telescopic movement has a certain component in the vertical direction, and the telescopic movement of the first end and the second end of the first telescopic mechanism 130 along the vertical direction can also drive the top plate 111 to move in the vertical direction relative to the bottom plate 112.

[0056] In the above embodiment, the base 110 further includes a connection cover 113 connecting the top plate 111 and the bottom plate 112 , and the connection cover 113 is configured as a retractable structure or includes a retractable structure.

[0057] That is to say, in this embodiment, the base 110 is a retractable base 110, and the lifting module 120 is not retractable. By setting the connection cover 113 connecting the top plate 111 and the bottom plate 112 as a retractable structure or including a retractable structure, in this way, when the first retractable mechanism 130 drives the top plate 111 to move in a vertical direction relative to the bottom plate 112, the retractable structure can be driven to move synchronously, so that during the process of the top plate 111 extending and retracting relative to the bottom plate 112, the base 110 is still a closed cavity, so that the base 110 still has a good protective effect on the structure installed inside the base 110, so as to ensure the overall reliability of the three-dimensional molding device 100.

[0058] When the first driving mechanism drives the top plate 111 and the bottom plate 112 to remain in the retracted state, the space occupied by the base 110 can be reduced to a greater extent, the length space of the light source projection can be fully compressed, and the molding quality can be improved. In addition, during the transportation process, the transportation cost can also be reduced to a certain extent.

[0059] In one example, the connection cover 113 is configured as a retractable structure, that is, the connection cover 113 connected between the bottom plate 112 and the top plate 111 is a retractable structure as a whole. This configuration facilitates the processing of the connection cover 113 and is suitable for mass production.

[0060] In another example, the connection cover 113 includes a retractable structure, that is, a part of the connection cover 113 connected between the bottom plate 112 and the top plate 111 is a retractable structure, and the other part is a fixed structure. This arrangement is beneficial to reducing the manufacturing cost of the connection cover 113.

[0061] In the above embodiment, the telescopic structure is a telescopic cover 114, and the telescopic cover 114 is configured as a flexible member, which is beneficial to improve the service life of the telescopic cover 114 and improve the reliability of the base 110. Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 , Fig.10 As shown, a portion of the connecting cover 113 is a telescopic structure.

[0062] Specifically, the telescopic cover 114 may be a flexible accordion protective cover.

[0063] Furthermore, if Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first telescopic mechanism 130 drives the top plate 111 to be in an extended state relative to the bottom plate 112, that is, the base 110 is in an extended state. Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, the first telescopic mechanism 130 drives the top plate 111 to be in a retracted state relative to the bottom plate 112 , that is, the base 110 is in a retracted state.

[0064] In some possible embodiments provided by the present invention, the lifting module 120 can be fixedly connected to the top plate 111, so that when the first telescopic mechanism 130 drives the top plate 111 to telescopically move in the vertical direction relative to the bottom plate 112, it can drive the lifting module 120 connected to the top plate 111 to move synchronously. In this way, during transportation, the first telescopic mechanism 130 can drive the top plate 111 to remain in a retracted state relative to the bottom plate 112 to reduce the overall volume of the three-dimensional molding device 100, thereby reducing the transportation cost without changing the printing range.

[0065] In some other possible embodiments provided by the present invention, the lifting module 120 is penetrated through the top plate 111 and fixedly connected to the bottom plate 112. Thus, when the first telescopic mechanism 130 drives the top plate 111 to telescope in the vertical direction relative to the bottom plate 112, the lifting module 120 connected to the bottom plate 112 is fixed. In this way, the top plate 111 can be driven by the first telescopic mechanism 130 to move vertically downward relative to the bottom plate 112, so that the top plate 111 and the bottom plate 112 remain in a retracted state, so as to increase the height difference between the top plate 111 and the top of the lifting module 120, thereby meeting the printing requirements of models with larger height requirements. Thus, the printing range is expanded without changing the volume of the three-dimensional molding equipment 100 and increasing the transportation cost.

[0066] like Figure 6 and Fig.13As shown, in some possible embodiments provided by the present invention, the first telescopic mechanism 130 includes a first electric telescopic rod, the first electric telescopic rod includes a first fixed end 131, and a first free end 132 that can telescopically move in a vertical direction relative to the first fixed end 131, the first fixed end 131 is connected to the bottom plate 112, and the first free end 132 is connected to the top plate 111, that is, the first fixed end 131 can be understood as the second end of the first telescopic mechanism 130, and the first free end 132 can be understood as the first end of the first telescopic mechanism 130. Thus, through the telescopic movement of the first electric telescopic rod, the telescopic movement of the top plate 111 relative to the bottom plate 112 in the vertical direction can be achieved. Among them, the first electric telescopic rod is small in size and high in motion accuracy, and can meet the accuracy requirements of the top plate 111 moving relative to the bottom plate 112 in the vertical direction. Furthermore, since the first electric telescopic rod can keep the first free end 132 in the current posture after the extension or retraction action stops, that is, the first electric telescopic rod has a self-locking function, it can ensure that the top plate 111 can stably maintain the current posture after the extension or retraction action relative to the bottom plate 112, thereby simplifying the setting of the locking mechanism and the post-lifting positioning structure. At the same time, the first electric telescopic rod can telescope and move in the vertical direction, which can reduce or avoid the shaking of the material trough 180, thereby reducing the risk of liquid leakage in the material trough 180 during the lifting and lowering of the top plate 111.

[0067] Specifically, the first fixed end 131 of the first electric telescopic rod can be a motor housing, which is fixedly connected to the bottom plate 112. The first free end 132 of the first electric telescopic rod can be a free end of the telescopic rod, which is connected to the top plate 111. Specifically, the first free end 132 and the top plate 111 can be connected by bolts, a clamping structure, a mortise and tenon structure, etc. Figure 1 It can be understood that when the first electric telescopic rod stops working, the first free end 132 can maintain the current posture to ensure that the top plate 111 can be maintained in a suitable position relative to the bottom plate 112. Figure 6 The first electric telescopic rod is in an extended state, so that the base 110 is as shown in FIG. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it is in the extended state. Fig.13 The first electric telescopic rod is in a retracted state, so that the base 110 is as shown in FIG. Fig. 9 , Fig.10 and Fig.11 As shown, it is in the retracted state.

[0068] In some possible embodiments provided in the present application, a plurality of first electric telescopic rods are arranged at intervals along the circumference of the top plate 111. Thus, by using a plurality of first electric telescopic rods, the stability and reliability of the top plate 111 moving relative to the bottom plate 112 in the vertical direction can be improved, the possibility of resin shaking in the material tank 180 can be reduced, and the leakage of the material tank 180 can be reduced or avoided, thereby ensuring good printing quality. The plurality of first electric telescopic rods can be two, three, four, five, or other numbers.

[0069] like Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, in the above embodiment, the four first electric telescopic rods are distributed in a rectangular shape at the bottom of the top plate 111, thereby allowing the top plate 111 to be evenly stressed and allowing the four first electric telescopic rods to move synchronously, thereby being able to reliably and stably drive the top plate 111 to move in a vertical direction relative to the bottom plate 112, thereby reducing the possibility of resin shaking in the trough 180 and ensuring good printing quality.

[0070] Specifically, the movement directions of the four first electric telescopic rods are all vertical directions. Figure 1 As shown in the Z direction in FIG. 1 , the top plate 111 moves in the vertical direction relative to the bottom plate 112, thereby reducing the possibility of vertical shaking in the trough 180 and ensuring good printing quality.

[0071] like Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, in some possible embodiments provided by the utility model, the telescopic mechanism includes a second telescopic mechanism 140, the lifting module 120 is passed through the top plate 111, the first end of the second telescopic mechanism 140 is fixedly connected to the bottom plate 112, the second end of the second telescopic mechanism 140 is fixedly connected to the lifting module 120 located in the base 110, and the relative telescopic movement between the first end and the second end of the second telescopic mechanism 140 includes at least a component in the vertical direction.

[0072] In this embodiment, the telescopic mechanism includes a second telescopic mechanism 140 that drives the lifting module 120 to move in the vertical direction relative to the bottom plate 112, that is, the base 110 in this embodiment is a non-retractable base, and the lifting module 120 is a retractable lifting module. Among them, the lifting module 120 is penetrated through the top plate 111, the first end of the second telescopic mechanism 140 is fixedly connected to the bottom plate 112, and the second end of the second telescopic mechanism 140 is fixedly connected to the lifting module 120 located in the base 110, that is, the two ends of the second telescopic mechanism 140 are respectively connected to the bottom plate 112 and the lifting module 120 located in the base 110, so that the second telescopic mechanism 140 drives the lifting module 120 to move in the vertical direction relative to the bottom plate 112, and can change the distance between the top of the lifting module 120 and the top plate 111. When printing, the second telescopic mechanism 140 drives the lifting module 120 to telescopically move relative to the bottom plate 112 in the vertical direction so that the lifting module 120 remains in an extended state, which can meet the printing needs of models with larger height requirements and expand the printing range. During transportation, the second telescopic mechanism 140 drives the lifting module 120 to move vertically downward relative to the top plate 111, so that the lifting module 120 remains in a retracted state, reducing the height difference between the top plate 111 and the top of the lifting module 120, so that the overall height of the three-dimensional molding device 100 is reduced, the volume is smaller, the space occupied by the device is smaller, and it is easy to transport and carry, thereby reducing transportation costs and saving labor costs.

[0073] Therefore, the three-dimensional molding device 100 can meet the printing needs of models with greater heights, expand the printing range, and reduce transportation costs, making it suitable for promotion and application.

[0074] The relative telescopic movement between the first end and the second end of the second telescopic mechanism 140 at least includes a component in the vertical direction. It can be understood that the relative telescopic movement between the first end and the second end of the second telescopic mechanism 140 is a telescopic movement in the vertical direction. In this way, the telescopic movement of the first end and the second end of the second telescopic mechanism 140 along the vertical direction can drive the lifting module 120 to move in the vertical direction relative to the bottom plate 112. Alternatively, the relative telescopic movement between the first end and the second end of the second telescopic mechanism 140 is inclined to the vertical direction, so that the telescopic movement has a certain component in the vertical direction, and the lifting module 120 can also be driven to move in the vertical direction relative to the bottom plate 112 by the telescopic movement of the first end and the second end of the second telescopic mechanism 140 along the vertical direction.

[0075] like Figure 7 and Fig.14As shown, in some possible embodiments provided by the present invention, the second telescopic mechanism 140 includes a second electric telescopic rod, the second electric telescopic rod includes a second fixed end 141, and a second free end 142 that can telescopically move in the vertical direction relative to the second fixed end 141, the second fixed end 141 is connected to the bottom plate 112, and the second free end 142 is connected to the top plate 111, that is, the second fixed end 141 can be understood as the first end of the second telescopic mechanism 140, and the second free end 142 can be understood as the second end of the telescopic mechanism 140. Thus, through the telescopic movement of the second electric telescopic rod, the telescopic movement of the lifting module 120 relative to the bottom plate 112 in the vertical direction can be realized. Among them, the second electric telescopic rod is small in size and high in motion accuracy, which can meet the accuracy requirements of the lifting module 120 moving in the vertical direction relative to the bottom plate 112. Furthermore, since the second free end 142 can be kept in the current posture after the extension or retraction action of the second electric telescopic rod stops, that is, the second electric telescopic rod has a self-locking function, it can ensure that the lifting module 120 can stably maintain the current posture after the extension or retraction action relative to the base plate 112, thereby simplifying the setting of the locking mechanism and the post-lifting locking structure.

[0076] Specifically, the second fixed end 141 of the second electric telescopic rod can be a motor housing, which is fixedly connected to the bottom plate 112. The second free end 142 of the second electric telescopic rod can be a free end of the telescopic rod. The second free end 142 is connected to the bottom end of the lifting module 120. Specifically, the second free end 142 and the lifting module 120 can be connected by bolts, a clamping structure, a mortise and tenon structure, etc. Figure 1 It is understandable that when the second electric telescopic rod stops working, the second free end 142 can maintain the current posture to ensure that the lifting module 120 can be maintained in a suitable position relative to the bottom plate 112. Figure 7 The second electric telescopic rod is in an extended state, so that the lifting module 120 is as shown. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, it is in the extended state. Fig.14 The second electric telescopic rod is in a retracted state, so that the lifting module 120 is as shown. Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.13 As shown, it is in the retracted state.

[0077] The bottom plate 112 and the lifting module 120 may be connected by a second electric telescopic rod to improve the stability and reliability of the vertical movement of the lifting module 120 relative to the bottom plate 112. Specifically, the number of the second electric telescopic rods may be two, three, four, or other numbers.

[0078] like Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, in some possible embodiments provided by the present invention, the three-dimensional molding device 100 further includes: a connecting seat 150, the connecting seat 150 is connected to the bottom end of the lifting module 120, and is connected to the second free end 142; wherein the connecting seat 150 is detachably connected to the lifting module 120, and the connecting seat 150 is detachably connected to the second free end 142. As a result, the connection between the lifting module 120 and the second free end 152 of the second telescopic mechanism 140 can be achieved through the connecting seat 150 without changing the original structure of the lifting module 120, so that the lifting module 120 has high versatility, that is, the three-dimensional molding device 100 including the second telescopic mechanism 140 and not including the second telescopic mechanism 140 can use the same lifting module 120, thereby realizing mass production of the lifting module 120, reducing manufacturing costs, and improving the versatility of the lifting module 120.

[0079] Furthermore, the connection base 150 and the second free end 142 are detachably connected, so that when the second motor telescopic rod fails, the second free end 142 is detached from the connection base 150, and at the same time, the second fixed end 141 is detached from the bottom plate 112, so that the second motor telescopic rod can be detached from the base 110 for maintenance without changing the structure of the lifting module 120. The operation is simple, which is conducive to improving the maintenance efficiency of the second motor telescopic rod. Specifically, the detachable connection between the second free end 142 and the connection base 150 can be achieved by bolts, a clamping structure, a mortise and tenon structure, etc. It is understandable that in some examples, the connection base 150 and the second free end 142 can also be fixedly connected by welding or bonding.

[0080] Furthermore, the lifting module 120 and the base 110 are detachably connected, so that when the lifting module 120 fails, the lifting module 120 and the base 110 can be separated for maintenance and replacement, and the structure of the second motor telescopic rod will not be affected. The operation is simple, which is conducive to improving the maintenance efficiency of the lifting module 120. Specifically, the lifting module 120 and the connecting seat 150 can be detachably connected by bolts, a clamping structure, a mortise and tenon structure, etc. It can be understood that in some examples, the connecting seat 150 and the lifting module 120 can also be fixedly connected by welding or bonding.

[0081] like Figure 7 and Fig.14 As shown, in some possible implementation examples provided by the present invention, the three-dimensional molding device 100 further includes: a guide module 160, which is arranged inside the base 110, and includes a guide column 161, and a linear bearing 162 which is sleeved on the outside of the guide column 161 and can slide along the guide column 161, the guide column 161 is arranged on the bottom plate 112 parallel to the lifting module 120, and the linear bearing 162 is connected to the connecting seat 150. Through the arrangement of the guide module 160, the movement of the lifting module 120 relative to the bottom plate 112 can be limited, the accuracy of the movement of the lifting module 120 in the vertical direction can be improved, the possibility of shaking of the printing platform 170 connected to the lifting module 120 can be reduced, and the printing quality can be improved.

[0082] Furthermore, since the guide column 161 of the guide module 160 is parallel to the lifting module 120, that is, the extension direction of the guide column 161 is parallel to the lifting module 120, Figure 1 The linear bearing 162 is connected to the connection seat 150, and the connection seat 150 is connected to the lifting module 120 and the second free end 142 of the second electric telescopic rod. Therefore, when the second telescopic rod drives the second free end 142 to move vertically to drive the lifting module 120 to move in the vertical direction relative to the bottom plate 112, the linear bearing 162 slides along the guide column 161, and the linear bearing 162 and the guide column 161 are used to limit the movement direction of the lifting module 120 relative to the bottom plate 112, so that the lifting module 120 can only rise and fall in the vertical direction, reducing the possibility of shaking of the printing platform 170 connected to the lifting module 120, which is conducive to ensuring good printing quality.

[0083] In the above embodiment, the connecting seat 150 is provided with an avoidance hole for avoiding the guide column 161. Since the linear bearing 162 will also move along the guide column 161 toward the bottom plate 112 during the process of the second telescopic mechanism 140 driving the lifting module 120 to move toward the bottom plate 112, there is a possibility that the top end of the guide column 161 interferes with and collides with the connecting seat 150, thereby preventing the lifting module 120 connected to the connecting seat 150 from continuing to move downward. Therefore, by providing an avoidance hole for avoiding the guide column 161 on the connecting seat 150, this phenomenon can be avoided, so that the lifting module 120 can move smoothly toward the bottom plate 112, so that the lifting module 120 can better maintain the retracted state, so that the overall volume of the three-dimensional molding equipment 100 is smaller, and the transportation cost is reduced.

[0084] like Figure 7 and Fig.14As shown, in the above embodiment, the number of guide columns 161 is two, and the linear bearing 162 is sleeved on the outer sides of the two guide columns 161 and moves along the two guide columns 161. Thus, the two guide columns 161 are used to limit the movement of the linear bearing 162 at the same time, which can reduce the occurrence of the linear bearing 162 tilting and offset on the column, thereby improving the accuracy of the linear bearing 162 moving in the vertical direction, improving the movement accuracy of the lifting module 120 in the vertical direction, and improving the printing quality.

[0085] like Figure 7 and Fig.14 As shown, in the above embodiment, the two second electric telescopic rods are distributed on both sides of the guide module 160. Thus, the two second electric telescopic rods are used to drive the lifting module 120 to telescopically move in the vertical direction relative to the base plate 112, which is beneficial to improving the stability and reliability of the movement of the lifting module 120, reducing the possibility of shaking of the printing platform 170 connected to the lifting module 120, and ensuring good printing quality.

[0086] In some possible embodiments provided by the present invention, the telescopic mechanism includes a third telescopic mechanism (not shown in the figure), the lifting module 120 includes a first section fixed in the base 110, and a second section passing through the top plate 111, the first section and the second section are nested and can move relatively, the first end of the third telescopic mechanism is fixedly connected to the first section, the second end of the third telescopic mechanism is fixedly connected to the second section located in the base 110, and the relative telescopic movement between the first end and the second end of the third telescopic mechanism includes at least a component in the vertical direction.

[0087] In this embodiment, the telescopic mechanism includes a third telescopic mechanism that drives the lifting module 120 to move in the vertical direction relative to the bottom plate 112, that is, the base 110 in this embodiment is a non-retractable base, and the lifting module 120 is a retractable lifting module. Among them, the lifting module 120 includes a first section located in the base 110, and a second section penetrating the top plate 111, and the first section and the second section are nested and can move relatively. In other words, the lifting module 120 itself is a segmented retractable structure. For example, the lifting module 120 is a structure similar to the retractable umbrella. The first section of the lifting module 120 can be fixedly connected to the bottom plate 112, and the second section of the lifting module 120 can be extended or retracted relative to the first section.

[0088] Thus, the first end of the third telescopic mechanism is fixedly connected to the first section of the lifting module 120, and the second end of the third telescopic mechanism is fixedly connected to the second section of the lifting module 120, that is, the two ends of the third telescopic mechanism connecting the lifting module 120 are connected to the first section and the second section respectively, so that the third telescopic mechanism drives the second section of the lifting module 120 to telescopically move relative to the first section in the vertical direction, and the distance between the top of the lifting module 120 and the top plate 111 can be changed. When printing, the third telescopic mechanism drives the second section of the lifting module 120 to telescopically move relative to the first section in the vertical direction so that the lifting module 120 remains in an extended state, which can meet the printing requirements of models with larger height requirements and expand the printing range. During transportation, the third telescopic mechanism drives the second section of the lifting module 120 to move vertically downward relative to the first section, so that the lifting module 120 remains in a retracted state, reducing the height difference between the top plate 111 and the top of the lifting module 120, so that the overall height of the three-dimensional molding device 100 is reduced, the volume is small, the space occupied by the device is small, and it is easy to transport and carry, so as to reduce transportation costs and save labor costs.

[0089] Therefore, the three-dimensional molding device 100 can meet the printing needs of models with greater heights, expand the printing range, and reduce transportation costs, making it suitable for promotion and application.

[0090] The relative telescopic movement between the first end and the second end of the third telescopic mechanism at least includes a component in the vertical direction. It can be understood that the relative telescopic movement between the first end and the second end of the third telescopic mechanism is a telescopic movement in the vertical direction. In this way, the telescopic movement of the first end and the second end of the third telescopic mechanism along the vertical direction can drive the second section of the lifting module 120 to move in the vertical direction relative to the first section. Alternatively, the relative telescopic movement between the first end and the second end of the third telescopic mechanism is inclined to the vertical direction, so that the telescopic movement has a certain component in the vertical direction, and the second section of the lifting module 120 can also be driven to move in the vertical direction relative to the first section through the telescopic movement of the first end and the second end of the third telescopic mechanism along the vertical direction.

[0091] Specifically, the third telescopic mechanism can be a third motor telescopic rod, which includes a third fixed end and a third free end, and the third free end can telescopically move in the vertical direction relative to the third fixed end, wherein the third fixed end is connected to the first section of the lifting module 120, and the third free end is connected to the second section of the lifting module 120, that is, the third fixed end can be understood as the first end of the third telescopic mechanism, and the third free end can be understood as the second end of the third telescopic mechanism. Thus, through the telescopic movement of the third electric telescopic rod, the telescopic movement of the second section of the lifting module 120 relative to the first section can be realized, and then the telescopic movement of the lifting module 120 relative to the bottom plate 112 in the vertical direction can be realized. Among them, since the third electric telescopic rod can keep the third free end in the current posture after the extension or retraction action stops, that is, the third electric telescopic rod has a self-locking function, it can ensure that the lifting module 120 can stably maintain the current posture after the extension or retraction action relative to the bottom plate 112, simplifying the setting of the locking mechanism and the post-lifting clamping structure.

[0092] like Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, in some possible embodiments provided by the present invention, the telescopic mechanism includes a first telescopic mechanism 130 and a second telescopic mechanism 140; the base 110 also includes a connecting cover 113 connecting the top plate 111 and the bottom plate 112, the connecting cover 113 is set to a telescopic structure or the connecting cover 113 includes a telescopic structure, a first end of the first telescopic mechanism 130 is fixedly connected to the top plate 111, a second end of the first telescopic mechanism 130 is fixedly connected to the bottom plate 112, and the relative movement between the first end and the second end of the first telescopic mechanism 130 at least includes a component in the vertical direction; the lifting module 120 is penetrated by the top plate 111, a first end of the second telescopic mechanism 140 is fixedly connected to the bottom plate 112, a second end of the second telescopic mechanism 140 is fixedly connected to the lifting module 120 located in the base 110, and the relative movement between the first end and the second end of the second telescopic mechanism 140 at least includes a component in the vertical direction.

[0093] In this embodiment, the base 110 of the three-dimensional molding device 100 is a telescopic base, and the lifting module 120 of the three-dimensional molding device 100 is a telescopic lifting module. Since the lifting module 120 is installed on the top plate 111, the lifting module 120 will not interfere with the movement of the top plate 111, and the movement of the top plate 111 will not interfere with the movement of the lifting module 120. Therefore, when printing is required, the first telescopic mechanism 130 can be used to drive the top plate 111 to move vertically downward relative to the bottom plate 112, so that the top plate 111 remains in a retracted state relative to the bottom plate 112. At the same time, the second telescopic mechanism 140 can be used to drive the lifting module 120 to move vertically upward relative to the top plate 111, so that the lifting module 120 and the top plate 111 remain in an extended state. As a result, the height difference between the top plate 111 and the top of the lifting module 120 can be greatly increased, and the height difference between the material trough 180 placed on the top plate 111 and the printing platform 170 on the lifting module 120 can be further increased, so that the three-dimensional molding equipment 100 can meet the printing needs of models with greater height requirements and expand the printing range. At the same time, when transportation is required, such as Figures 8 to 14 As shown, the top plate 111 and the bottom plate 112 are kept in the retracted state by the first telescopic mechanism 130, and the lifting module 120 is driven to move vertically downward relative to the top plate 111 by the second telescopic mechanism 140, so that the lifting module 120 and the top plate 111 are kept in the retracted state, so that the overall height of the three-dimensional molding device 100 is reduced, and the overall volume and height of the three-dimensional molding device 100 are reduced, which brings convenience to handling and transportation. Thereby reducing the manpower and cost during transportation. As a result, the three-dimensional molding device 100 can meet the printing requirements of models with larger heights, and at the same time, it can reduce transportation costs, which is suitable for promotion and application.

[0094] Among them, the top plate 111 and the bottom plate 112 of the base 110 are connected by a connecting cover 113, and the connecting cover 113 is set to a retractable structure or the connecting cover 113 includes a retractable structure. In this way, in the process of the first retractable mechanism 130 driving the top plate 111 to retract and move relative to the bottom plate 112 in the vertical direction, the retractable structure can be driven to move synchronously, so that during the process of the top plate 111 retracting and moving relative to the bottom plate 112, the base 110 is still a closed cavity, so that the base 110 still has a good protective effect on the structure installed inside the base 110, so as to ensure the overall reliability of the three-dimensional molding equipment 100.

[0095] In one example, the connection cover 113 is configured as a retractable structure, that is, the connection cover 113 connected between the bottom plate 112 and the top plate 111 is a retractable structure as a whole. This configuration facilitates the processing of the connection cover 113 and is suitable for mass production.

[0096] In another example, the connection cover 113 includes a retractable structure, that is, a part of the connection cover 113 connected between the bottom plate 112 and the top plate 111 is a retractable structure, and the other part is a fixed structure. This arrangement is beneficial to reducing the manufacturing cost of the connection cover 113.

[0097] In the above embodiment, the telescopic structure is a telescopic cover 114, and the telescopic cover 114 is configured as a flexible member, which is beneficial to improve the service life of the telescopic cover 114 and improve the reliability of the base 110. Specifically, the telescopic cover 114 can be a flexible accordion protective cover.

[0098] like Figure 6 and Fig.13 As shown, in some possible embodiments provided by the present invention, the first telescopic mechanism 130 includes a first electric telescopic rod, the first electric telescopic rod includes a first fixed end 131, and a first free end 132 that can telescopically move in a vertical direction relative to the first fixed end 131, the first fixed end 131 is connected to the bottom plate 112, and the first free end 132 is connected to the top plate 111. Thus, through the telescopic movement of the first electric telescopic rod, the telescopic movement of the top plate 111 relative to the bottom plate 112 in the vertical direction can be achieved. The relevant description of the first electric telescopic rod has been recorded above and will not be repeated here.

[0099] In the above embodiment, a plurality of first electric telescopic rods are arranged at intervals along the circumference of the top plate 111. Thus, by using a plurality of first electric telescopic rods, the stability and reliability of the top plate 111 moving relative to the bottom plate 112 in the vertical direction can be improved, the possibility of resin shaking in the trough 180 can be reduced, and good printing quality can be ensured. The plurality of first electric telescopic rods can be two, three, four, five, or other numbers. Specifically, the four first electric telescopic rods are distributed in a rectangular shape at the bottom of the top plate 111, thereby allowing the top plate 111 to be evenly stressed.

[0100] like Figure 7 and Fig.14 As shown, in some possible embodiments provided by the present invention, the second telescopic mechanism 140 includes a second electric telescopic rod, the second electric telescopic rod includes a second fixed end 141, and a second free end 142 that can telescopically move in a vertical direction relative to the second fixed end 141, the second fixed end 141 is connected to the bottom plate 112, and the second free end 142 is connected to the top plate 111. Thus, the telescopic movement of the lifting module 120 relative to the bottom plate 112 in the vertical direction can be achieved through the telescopic movement of the second electric telescopic rod. The relevant description of the second electric telescopic rod has been recorded above and will not be repeated here. Specifically, the number of the second electric telescopic rods can be two, three, four, or other numbers.

[0101] in, Figure 6, Figure 7 The first electric telescopic rod and the second electric telescopic rod are both in an extended state, so that the base 110 and the lifting module 120 are as shown. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, it is in the extended state. Fig.13 , Fig.14 The first electric telescopic rod and the second electric telescopic rod are both in a retracted state, so that the base 110 and the lifting module 120 are as shown. Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown, it is in the retracted state.

[0102] like Figure 6 , Figure 7 , Fig.13 and Fig.14 As shown, in some possible embodiments provided by the present invention, the three-dimensional forming device 100 further includes: a connecting seat 150, which is connected to the bottom end of the lifting module 120 and connected to the second free end 142; wherein the connecting seat 150 is detachably connected to the lifting module 120, and the connecting seat 150 is detachably connected to the second free end 142. The relevant structure and technical effects of the connecting seat 150 have been described above and will not be repeated here.

[0103] like Figure 7 and Fig.14 As shown, in some possible implementation examples provided by the present invention, the three-dimensional molding device 100 further includes: a guide module 160, which is arranged inside the base 110 and includes a guide column 161, and a linear bearing 162 sleeved on the outer side of the guide column 161 and slidable along the guide column 161, the guide column 161 is arranged on the bottom plate 112 parallel to the lifting module 120, and the linear bearing 162 is connected to the connecting seat 150. The relevant structure and technical effect description of the guide module 160 have been recorded above and will not be repeated here.

[0104] In the above embodiment, the connecting seat 150 is provided with an avoidance hole for avoiding the guide column 161 . The description of the avoidance hole has been recorded above and will not be repeated here.

[0105] like Figure 7 and Fig.14As shown, in the above embodiment, the number of guide columns 161 is two, and the linear bearing 162 is sleeved on the outer sides of the two guide columns 161 and moves along the two guide columns 161. Thus, the two guide columns 161 are used to limit the movement of the linear bearing 162 at the same time, which can reduce the occurrence of the linear bearing 162 tilting and offset on the column, thereby improving the accuracy of the linear bearing 162 moving in the vertical direction, improving the movement accuracy of the lifting module 120 in the vertical direction, and improving the printing quality.

[0106] like Figure 7 and Fig.14 As shown, in the above embodiment, the two second electric telescopic rods are distributed on both sides of the guide module 160. Thus, the two second electric telescopic rods are used to drive the lifting module 120 to telescopically move in the vertical direction relative to the base plate 112, which is beneficial to improving the stability and reliability of the movement of the lifting module 120, reducing the possibility of shaking of the printing platform 170 connected to the lifting module 120, and ensuring good printing quality.

[0107] In a specific example, the stereoscopic molding device 100 includes four first telescopic mechanisms 130 and two second telescopic mechanisms 140, that is, the base 110 is a telescopic base, and the lifting module 120 is a telescopic lifting module. Figures 1 to 7 As shown, when the three-dimensional molding device is in working state, the positions of the top plate 111 and the bottom plate 112 are adjusted through the four first telescopic mechanisms 130 inside the base 110, that is, the four first motor telescopic rods, so that the top plate 111 is lifted to the set height of the printer, and the lifting module 120 is also lifted to the working position through the second telescopic mechanism 140 inside the base 110, such as the two second motor telescopic rods, so that the material trough 180 and the lifting module 120 of the three-dimensional molding device 100 reach the working height. It can be understood that in the set working state, the three-dimensional molding device 100 will not change the working state of the first telescopic mechanism 130 and the second telescopic mechanism 140 when it is on standby or turned off, that is, the first telescopic mechanism 130 and the second telescopic mechanism 140 will still keep the top plate 111 and the lifting module 120 at the working height, waiting for the user to print at any time.

[0108] It can be understood that in one example, when the base 110 and the lifting module 120 are both in the extended state, the four first telescopic mechanisms 130 drive the top plate 111 to move downward relative to the bottom plate 112 so that the bottom plate 112 is in the retracted state, which can increase the distance between the bottom plate 112 and the top of the lifting module 120, thereby meeting the printing requirements of models with larger heights, expanding the printing range, and will not increase transportation costs.

[0109] It can be understood that, in another example, when the base 110 and the lifting module 120 are both in the extended state, the two second telescopic mechanisms 140 are used to drive the lifting module 120 to move downward relative to the bottom plate 112 so that the bottom plate 112 is in the retracted state. This can reduce the height of the lifting module 120 outside the base 110, reduce the overall height and volume of the three-dimensional forming equipment 100, facilitate handling and transportation, and effectively reduce transportation costs and manpower.

[0110] Furthermore, if Figures 8 to 14 As shown, when the stereoscopic molding device is in the transport state, the top plate 111 can be driven to move downward relative to the bottom plate 112 by the four first telescopic mechanisms 130 so that the bottom plate 112 is in a retracted state, and the lifting module 120 can be driven to move downward relative to the bottom plate 112 by the two second telescopic mechanisms 140 so that the bottom plate 112 is in a retracted state, so that both the top plate 111 and the lifting module 120 are retracted to the lowest position to reduce the overall volume and height of the stereoscopic molding device 100, bringing convenience to handling and transportation. Thus, the manpower and cost in the transportation process are reduced.

[0111] It can be understood that since the telescopic directions of the first telescopic mechanism 130 and the second telescopic mechanism 140 are both vertical directions, when the telescopic speed is within an appropriate range and the height of the resin in the material trough 180 is within a reasonable range, such as when the telescopic speed is not particularly fast and the resin is not particularly full, the first telescopic mechanism 130 and / or the second telescopic mechanism 140 is actuated, the resin in the material trough 180 on the base 110 will not shake, and the printing platform 170 on the lifting module 120 will not shake, thereby not affecting the printing quality, so that the three-dimensional molding equipment 100 has good printing quality.

[0112] In some possible embodiments provided by the present invention, the telescopic mechanism includes a first telescopic mechanism 130 and a third telescopic mechanism; the base 110 also includes a connecting cover 113 connecting the top plate 111 and the bottom plate 112, the connecting cover 113 is set to a telescopic structure or the connecting cover 113 includes a telescopic structure, the first end of the first telescopic mechanism 130 is fixedly connected to the top plate 111, the second end of the first telescopic mechanism 130 is fixedly connected to the bottom plate 112, and the relative movement of the first end and the second end of the first telescopic mechanism 130 includes at least a component in the vertical direction; the lifting module 120 includes a first section fixed in the base 110, and a second section penetrating the top plate 111, the first section and the second section are nested and can move relatively, the first end of the third telescopic mechanism is fixedly connected to the first section, the second end of the third telescopic mechanism is fixedly connected to the second section located in the base 110, and the relative telescopic movement of the first end and the second end of the third telescopic mechanism includes at least a component in the vertical direction.

[0113] In this embodiment, the base 110 of the three-dimensional molding device 100 is a telescopic base, and the lifting module 120 of the three-dimensional molding device 100 is a segmented telescopic lifting module. Since the lifting module 120 is installed on the top plate 111, the lifting module 120 will not interfere with the movement of the top plate 111, and the movement of the top plate 111 will not interfere with the movement of the lifting module 120. Therefore, when printing is required, the first telescopic mechanism 130 can be used to drive the top plate 111 to move vertically downward relative to the bottom plate 112, so that the top plate 111 remains in a retracted state relative to the bottom plate 112. At the same time, the second section of the lifting module 120 is driven to move vertically upward relative to the first section by the third telescopic mechanism, so that the lifting module 120 and the top plate 111 remain in an extended state. As a result, the height difference between the top plate 111 and the top of the lifting module 120 can be greatly increased, and the height difference between the material trough 180 placed on the top plate 111 and the printing platform 170 on the lifting module 120 can be further increased, so that the three-dimensional molding equipment 100 can meet the printing needs of models with greater height requirements and expand the printing range. At the same time, when transportation is required, the top plate 111 and the bottom plate 112 are kept in the retracted state through the first telescopic mechanism 130, and the second section of the lifting module is driven to move vertically downward relative to the first section through the third telescopic mechanism, so that the lifting module 120 and the top plate 111 are kept in the retracted state, so that the overall height of the three-dimensional molding device 100 is reduced, and the overall volume and height of the three-dimensional molding device 100 are reduced, which brings convenience to handling and transportation. Thereby reducing the manpower and cost during transportation. As a result, the three-dimensional molding device 100 can meet the printing needs of models with larger heights, and at the same time, it can reduce transportation costs, which is suitable for promotion and application.
