Description

Technical Field

[0001] The present application relates to the technical field of photocuring, and more specifically, to a 3D printer. Background Art

[0002] With the development of science and technology, 3D printers are increasingly widely used in the manufacturing industry due to their simple molding process, low cost and exquisite finished products.

[0003] In a conventional 3D printer, after a complete model (such as a dental model) is printed on a printing platform, it is necessary to use a push rod inside the 3D printer to push the model off the printing platform, and then use a scraper to scrape the model from the printing platform to a storage box. Therefore, the printing platform can only continue with the next round of model printing after the model completely leaves the printing platform, which results in low printing efficiency of the 3D printer.

DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0036] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] Combination Figures 1 to 11As shown, the present application protects a 3D printer 10, which includes a shelf 100, a support assembly 200, a conveying mechanism 300 and an exposure module 400. The shelf 100 is arranged with a plurality of printing platforms 500 along the Z-axis direction. The support assembly 200 includes a support table 210 and a locking member 220 mounted on the support table 210. The support table 210 is located on one side of the shelf 100 along the X-axis direction and can support the printing platform 500. The exposure module 400 is located above the support table 210 along the Z-axis and can expose and cure the printing material attached to the upper surface of the printing platform 500 located on the support table 210. The conveying mechanism 300 includes a clamp 310 and a trigger 320 connected to the clamp 310. The clamp 310 can clamp the printing platform 500 and drive the printing platform 500 to move between the shelf 100 and the support platform 210. The trigger 320 moves with the clamp 310 and can trigger the locking member 220 to lock the printing platform 500 on the support platform 210.

[0039] In the 3D printer 10 of the present application, a large number of vacant printing platforms 500 can be placed on the shelf 100 along the Z-axis direction, and the conveying mechanism 300 can clamp the vacant printing platform 500 from the shelf 100 and transport it to the support table 210, and the conveying mechanism 300 can trigger the locking member 220 to lock the printing platform 500 on the support table 210. After the printing material is attached to the upper surface of the printing platform 500, the exposure module 400 can expose and cure the printing material. After the model (such as dental membrane) on the printing platform 500 is printed, the conveying mechanism 300 can be used to release the printing material. 0 can unlock the printing platform 500 from the support table 210, and move the printing platform 500 carrying the model from the support table 210 to the shelf 100, so that the conveying mechanism 300 can transport the printing platform 500 back and forth to improve the printing efficiency of the 3D printer 10. After all the empty printing platforms 500 on the shelf 100 are printed with models, the shelf 100 can be moved away and replaced with another shelf 100 full of empty printing platforms 500, and the moved shelf 100 can be further transferred to the operating equipment that pushes and scrapes the model off the printing platform 500.

[0040] In addition, in the 3D printer 10 of the present application, since the locking member 220 can stably lock the printing platform 500 on the support table 210 without moving, and the model is formed on the upper surface of the printing platform 500, the printing platform 500 can carry a large number of models during the model printing process, thereby reducing the replacement frequency of the printing platform 500 and improving the 3D printing efficiency. Further, by setting a trigger 320 on the fixture 310 in the conveying mechanism 300, the fixture 310 can be moved between the support table 210 and the shelf 100 to transport the printing platform 500, and the fixture 310 can also be used to drive the trigger 320 to move and trigger the locking member 220 to lock the printing platform 500 on the support table 210. In this way, the trigger 320 and the fixture 310 can share a set of driving structures, and there is no need to set up additional structural members to drive the trigger 320 to move. This can greatly reduce the structural complexity of the 3D printer 10, thereby reducing the manufacturing cost.

[0041] In the present application, the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0042] Combination Figures 5 to 10 As shown, specifically in the present application, the locking member 220 can move relative to the support platform 210 under the drive of the trigger member 320 and has a first state of being engaged with the printing platform 500 and a second state of not being engaged with the printing platform 500. In the first state, the printing platform 500 is locked on the support platform 210, and in the second state, the printing platform 500 can move relative to the support platform 210. It can be understood that the trigger member 320 moves under the drive of the clamp 310, and the trigger member 320 further drives the locking member 220 to move in a mechanically driven manner, so that the locking member 220 locks the printing platform 500 on the support platform 210 in a mechanically engaged manner. The design scheme of the locking member 220 locking the printing platform 500 on the support platform 210 by engaging is relatively simple, and no other electrical auxiliary structures need to be set, which can reduce the complexity of the structure and save costs. In other embodiments, the actuator 320 can also drive the locking member 220 to move by magnetic control or electrical control, and the locking member 220 can lock the printing platform 500 on the support table 210 by other methods such as magnetic locking or clamping locking.

[0043] Combination Figures 5 to 10As shown, specifically, the printing platform 500 includes a platform body 510 and a staple 520 connected to the lower surface of the platform body 510 along the Z-axis direction. The support platform 210 is provided with a plug hole 211 along the Z-axis direction, and a slide groove 212 connected to the plug hole 211 is provided in a direction perpendicular to the Z-axis direction; the locking member 220 is slidably arranged in the slide groove 212, and is provided with a clamping hole 221 that can be connected to the plug hole 211. In the second state, the clamping hole 221 is aligned with the plug hole 211, and the staple 520 can extend into the clamping hole 221 through the plug hole 211. In the first state, the locking member 220 is engaged with the staple 520 because the clamping hole 221 is misaligned with the plug hole 211. By providing the support platform 210 and the locking member 220 with hole structures such as the insertion hole 211 and the locking hole 221, after the staple 520 extends into the locking hole 221 through the insertion hole 211, and cooperates with the locking member 220 to slide along the slide groove 212 relative to the support platform 210, the relative position of the locking hole 221 and the insertion hole 211 can be changed, thereby achieving the engagement of the locking member 220 and the staple 520, thereby locking the staple 520 in the locking hole 221, and achieving the purpose of locking the printing platform 500 and the support platform 210 relative to each other. It can be understood that in the present application, the trigger 320 drives the locking member 220 to perform a linear motion of translation relative to the support platform 210 along the slide groove 212. Specifically, in the present application, the locking member 220 slides relative to the support platform 210 along the Y-axis direction under the drive of the trigger 320.

[0044] In the present application, the support platform 210 includes a support beam 213 and a support block 214. The support block 214 is fixedly mounted on the support beam 213 and is higher than the support beam 213 in the Z-axis direction, so that when the printing platform 500 is placed on the support platform 210, the printing platform 500 is supported by the support block 214. Furthermore, the insertion hole 211 and the slide groove 212 are both provided on the support block 214.

[0045] In other embodiments, the locking member 220 can also be driven by the trigger member 320 to slide relative to the support platform 210 along the X-axis direction, or the locking member 220 can be driven by the trigger member 320 to slide relative to the support platform 210 along any direction within the plane defined by the X-axis direction and the Y-axis direction. Alternatively, the locking member 220 can be driven by the trigger member 320 to rotate around a predetermined center point, both of which can achieve the purpose of engaging the locking member 220 with the staple 520.

[0046] Combination Figures 5 to 10As shown, specifically in the embodiment of the present application, the staple 520 includes a first connecting column 521, a first limiting protrusion 522, a second connecting column 523 and a second limiting protrusion 524 connected in sequence. The first connecting column 521 is connected to the platform body 510, the first limiting protrusion 522 and the second limiting protrusion 524 both protrude from the outer wall surface of the second connecting column 523, and the first limiting protrusion 522 can be inserted into the insertion hole 211 along the Z-axis direction, and its outer peripheral surface is in contact with the inner wall surface of the insertion hole 211. The locking hole 221 includes an alignment hole 222 and a guide hole 223 along the sliding direction of the locking member 220. The guide hole 223 is connected to the alignment hole 222, and the aperture thereof is smaller than that of the alignment hole 222. When the alignment hole 222 is aligned with the insertion hole 211, the second limiting protrusion 524 and the second connecting column 523 can extend into the alignment hole 222. When the alignment hole 222 is misaligned with the insertion hole 211, the second connecting column 523 is guided from the alignment hole 222 into the guide hole 223, and the second limiting protrusion 524 abuts against the lower surface of the locking member 220 along the Z-axis direction.

[0047] It can be understood that when the alignment hole 222 is aligned with the insertion hole 211, since the aperture of the alignment hole 222 is larger, the second limiting protrusion 524 and the second connecting column 523 can both extend into the alignment hole 222, and at this time, the first limiting protrusion 522 just extends into the insertion hole 211. In the process of the locking member 220 sliding along the slide groove 212 relative to the support platform 210, the alignment hole 222 is gradually misaligned with the insertion hole 211, and the second connecting column 523 is gradually introduced into the smaller aperture. In the guide hole 223 of the printing platform 500, the locking member 220 will block the second limiting protrusion 524 from withdrawing from the guide hole 223 in the Z-axis direction. In this way, the movement of the staple 520 in the Z-axis direction can be locked by the lower surface of the locking member 220 in the Z-axis direction abutting against the second limiting protrusion 524, and the outer wall surface of the first limiting protrusion 522 is in close contact with the inner wall surface of the insertion hole 211, so that the movement of the staple 520 in the horizontal plane perpendicular to the Z-axis direction can be locked. It should be pointed out that when the lower surface of the locking member 220 in the Z-axis direction abuts against the second limiting protrusion 524, the lower surface of the platform body 510 of the printing platform 500 also happens to be in close contact with the upper surface of the support platform 210. In this way, the printing platform 500 can be stably locked on the support platform 210 by the sliding of the locking member 220 relative to the support platform 210.

[0048] Combination Figures 5 to 10As shown, specifically, the trigger 320 is a latch fixed to the fixture 310, and the locking member 220 is provided with a slot 224 along the Z-axis direction, and the latch can be inserted into the slot 224, and the locking member 220 is driven to move relative to the support platform 210 as the fixture 310 moves. It can be understood that the trigger 320 can be aligned and inserted into the slot 224 through the relative movement of the fixture 310 and the support platform 210 perpendicular to the Z-axis direction. In the present application, the clamp 310 drives the touch member 320 to move along the X-axis direction and the Y-axis direction, so that the touch member 320 can be aligned with the slot 224 in the Z-axis direction, and the support table 210, driven by the second drive component 620 (which will be mentioned later), will drive the locking member 220 to rise and fall, so that the touch member 320 is inserted into the slot 224, and then through the movement of the clamp 310 along the Y-axis direction, the touch member 320 can drive the locking member 220 to slide relative to the support table 210.

[0049] Specifically in the present application, the two clamping jaws 311 of the clamp 310 are each provided with a triggering member 320, and the support platform 210 is also connected with locking members 220 on both sides opposite to each other in the Y-axis direction. Therefore, the two clamping jaws 311 can act synchronously to drive multiple locking members 220 to slide relative to the support platform 210 at the same time, so that the multiple locking members 220 can work together to quickly lock or unlock the printing platform 500 and the support platform 210.

[0050] Combination Figures 1 to 5 As shown, specifically in the present application, the support table 210 is provided with a plurality of support positions 215 corresponding to the printing platforms 500, and a plurality of locking members 220 are correspondingly installed at any support position 215. By providing a plurality of support positions 215 on the support table 210, the conveying mechanism 300 can carry a plurality of printing platforms 500 on the support table 210, so that a plurality of printing platforms 500 can print models at the same time, which can greatly improve the 3D printing efficiency. By providing a plurality of locking members 220 at each support position 215, each printing platform 500 placed at the support position 215 can be stably locked on the support table 210 under the joint action of a plurality of locking members 220, and the problem of the printing platform 500 moving relative to the support table 210 and causing the model printing error will not occur.

[0051] Further, there are multiple exposure modules 400, and any support position 215 corresponds to at least one exposure module 400. It can be understood that multiple exposure modules 400 can be set in one-to-one correspondence with multiple support positions 215, or any of the support positions 215 corresponds to multiple exposure modules 400, so that multiple exposure modules 400 can work together to simultaneously expose and cure the printing materials attached to the multiple printing platforms 500 on the support table 210. In this way, the 3D printer 10 can print and shape a large number of models in a large area at one time, thereby improving the 3D printing efficiency.

[0052] Combination Figures 1 to 4 As shown, specifically in the present application, the 3D printer 10 includes a frame 610, a second drive assembly 620 and a material slot 630 for accommodating printing materials, and the second drive assembly 620 is connected between the frame 610 and the support table 210 to drive the support table 210 to rise and fall along the Z-axis direction, and the support table 210 rises and falls along the Z-axis direction to be able to enter or exit the material slot 630. It can be understood that the frame 610 supports the support table 210 and the second drive assembly 620 mounted thereon. In the present application, the material slot 630 and the exposure module 400 are also mounted on the frame 610, and the frame 610 also supports the material slot 630 and the exposure module 400. In other embodiments, the material slot 630 may not be mounted on the frame 610. In the present application, the support table 210 is driven by the second driving assembly 620 to rise and fall in the Z-axis direction, so that the printing platform 500 locked on the support table 210 can also rise and fall with the support table 210, so that after the support table 210 drives the printing platform 500 into the material tank 630, the printing platform 500 will be immersed in the printing material in the material tank 630, so that after the printing platform 500 exits the material tank 630 with the support table 210, the printing material will adhere to the printing platform 500, and the printing material in the partial area of ​​the printing platform 500 exposed by the exposure module 400 will solidify and finally form the desired model.

[0053] In the present application, the second drive assembly 620 is a device combination composed of structural parts such as a motor, a lead screw, a nut, a slide rail, and a slider. In other embodiments, the fourth drive assembly can also be a drive device that directly outputs a linear motion along the Z-axis direction by a cylinder or an electric cylinder to drive the support table 210 to rise and fall.

[0054] Combination Figures 1 to 3As shown, specifically in the present application, the 3D printer 10 includes a third driving component 640 and a scraper plate 650. The third driving component 640 is connected between the frame 610 and the scraper plate 650 to drive the scraper plate 650 to translate relative to the frame 610 along the X-axis direction or along the Y-axis direction so as to flatten the printing material attached to the upper surface of the printing platform 500 located on the support table 210. It can be understood that after the printing platform 500 exits the material slot 630 along with the support table 210, the printing material attached to the printing platform 500 may be uneven. By driving the scraper plate 650 to move by the third driving component 640, the scraper plate 650 can flatten the printing material attached to the printing platform 500, which helps to improve the printing accuracy of the model. In the present application, the third driving assembly 640 drives the scraper plate 650 to translate along the Y-axis direction. When the scraper plate 650 is not needed for the leveling operation, the scraper plate 650 is located on one side of the support table 210 along the Y-axis direction without interfering with the conveying mechanism 300 in carrying the printing platform 500 to the support table 210, and without interfering with the lifting of the support table 210 along the Z-axis direction. In other embodiments, the third driving assembly 640 can also drive the scraper plate 650 to translate along the X-axis direction, which can also achieve the purpose of leveling the printing material.

[0055] In the present application, the third driving assembly 640 is a device combination composed of structural parts such as a motor, a gear, a rack, a slide rail, and a slider. In other embodiments, the third driving assembly 640 can also be a driving device that directly outputs a linear motion along the Y-axis direction by a cylinder or an electric cylinder to drive the scraper plate 650 to translate.

[0056] Combination Figure 3 and Figure 5 As shown, specifically in the present application, the conveying mechanism 300 includes a first driving assembly 330, and the clamp 310 includes two clamps 311. The first driving assembly 330 is connected to the two clamps 311 to drive the two clamps 311 to move synchronously along the X-axis direction, and can drive the two clamps 311 to move closer to each other along the Y-axis direction to clamp the printing platform 500 or move away from each other to release the printing platform 500. It can be understood that the movement of the two clamps 311 in the X-direction is synchronous, so that the two can always remain in direct opposition, and then it is convenient to face the two opposite sides of the printing platform 500 respectively, and clamp or release the printing platform 500 by moving the two clamps 311 closer to or farther away from each other along the Y-axis direction. In the present application, the two clamps 311 are both extended in the X-direction in a long strip shape, so that they can have a large contact area with the printing platform 500 and stably clamp the printing platform 500.

[0057] In some embodiments, the shelf 100 is located on one side of the support table 210 along the X-axis direction, and the multiple support positions 215 on the support table 210 are also arranged in sequence along the X-axis direction. In this way, the clamping claws 311 extending along the X-axis direction can also clamp multiple printing platforms 500 from the shelf 100 at one time, and move the multiple printing platforms 500 to positions on the support table 210 corresponding to the multiple support positions 215 one by one, which also helps to improve 3D printing efficiency.

[0058] Combination Figures 1 to 5 As shown, specifically, since the support table 210 can be raised and lowered along the Z-axis direction under the drive of the second drive assembly 620, in this case, the fixture 310 only needs to move in the X-axis direction and the Y-axis direction, and the printing platform 500 clamped by the fixture 310 is placed on the support table 210 through the movement of the support table 210 in the Z-axis direction, or the fixture 310 moves the printing platform 500 away from the support table 210. In this way, the movement of the support table 210 that needs to be raised and lowered along the Z-axis direction to enter or exit the material tank 630 can be fully utilized, making the movement design of the fixture 310 simpler, and also making the structure of the first drive assembly 330 that drives the fixture 310 to move simpler, saving costs. In the present application, the first drive assembly 330 is a device combination composed of structural parts such as electric cylinders, gantry beams, cylinders, slide rails, and sliders.

[0059] Combination Figure 1 and Fig.11 As shown, specifically in the present application, the 3D printer 10 includes a fourth drive assembly 660, which is connected to the shelf 100 to drive the shelf 100 to rise and fall along the Z-axis direction. It can be understood that the shelf 100 can be lifted and lowered under the driving action of the fourth drive assembly 660, so that the target position on the shelf 100 corresponding to the printing platform 500 carried by the conveying mechanism 300 can be brought to the height that is most convenient for the conveying mechanism 300 to carry, thereby saving the time for the conveying mechanism 300 to find the target position from the shelf 100, thereby shortening the time spent by the conveying mechanism 300 to carry the printing platform 500, and improving the 3D printing efficiency. Specifically, the fourth drive assembly 660 is a device combination composed of structural parts such as a motor, a belt, a pulley, a lead screw, a nut, a slide rail, and a slider. In other embodiments, the fourth drive assembly 660 can also be a drive device that directly outputs a linear motion along the Z-axis direction by a cylinder or an electric cylinder to drive the shelf 100 to rise and fall.

[0060] Specifically, in the present application, a connecting column 662 is provided on the upper surface of the slider 661 in the fourth driving assembly 660 along the Z-axis direction, a connecting hole 110 is opened on the shelf 100, the shelf 100 is placed on the slider 661, and the connecting column 662 passes through the connecting hole 110, so that the slider 661 can support the shelf 100 in the Z-axis direction, and with the cooperation of the connecting column 662 and the connecting hole 110, the shelf 100 and the slider 661 maintain a stable connection and will not detach from the slider 661.

[0061] Combination Figure 2 and Figure 4 As shown, specifically in the embodiment of the present application, the material trough 630 is slidably connected to the frame 610 along the Z-axis direction, so that it can be lifted and lowered relative to the frame 610 in the Z-axis direction, so that the operator can easily replace the material trough 630. Specifically, the 3D printer 10 also includes a fifth drive assembly 670, which is connected between the material trough 630 and the frame 610 to drive the material trough 630 to move along the Z-axis direction. The fifth drive assembly 670 is a device combination composed of structural parts such as a motor, a gear, a rotating shaft, and a linear bearing. In the present application, the 3D printer 10 also includes a rehydration pump 680, which is fixedly mounted on the frame 610 and can automatically replenish the material trough 630 with printing materials according to the liquid level of the printing material in the material trough 630. Specifically, the rehydration pump is a peristaltic pump.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
