Description

Technical Field

[0001] This application relates to the field of 3D printing technology, and more particularly to a 3D printing device and its component structure. Background Technology

[0002] Photopolymer 3D solid printing technology is a type of rapid prototyping technology. It typically uses liquid photosensitive resin, photosensitive polymer, and other materials as curing materials. The printed model is divided into multiple cross-sections, and then a three-dimensional object is constructed by printing layer by layer. Due to its high forming accuracy, it has a wide range of applications in molds, customized products, medical devices, prostheses, and other fields.

[0003] Generally, after 3D printing, the printed 3D object needs to be manually removed from the component plate using a scraper. This method is inefficient and can damage the 3D object. Therefore, some manufacturers remove the 3D object along with the component plate from the printing equipment. However, the assembly and disassembly structures of these detachable component devices are complex, making rapid assembly and disassembly impossible, which affects both removal and printing efficiency.

[0004] Therefore, how to achieve rapid assembly and disassembly of component boards relative to the printing equipment to ensure component retrieval efficiency and printing efficiency is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0035] In view of the technical problems mentioned in the background art, this application discloses a 3D printing device and its component mechanism. By setting a detachable component device connected to the mounting base, the component plate can be removed together with the three-dimensional object, improving operational convenience. By setting a first joint in the first mounting structure of the mounting base and a second joint in the second mounting structure of the component device, the component device can be installed on the mounting base through the guiding action of the first and second joints. By setting a rotatable rotating component in the mounting base and combining it with the linkage component on the component device, the installation and disassembly of the component device can be completed without the need for additional tools, simply by the counterforce provided by the force-applying component in the linkage component, further improving operational convenience and ensuring part removal efficiency and printing efficiency.

[0036] Some embodiments disclosed in this application disclose a 3D printing device. Whether based on top-exposure or bottom-exposure, a component plate serves as a platform for the 3D printed solid component, constructing a three-dimensional object through layer-by-layer printing. During printing, the resin liquid is first irradiated by an energy radiation system to form a first cured layer. This first cured layer adheres to the component plate. The component plate rises or falls a predetermined distance under the action of a Z-axis movement mechanism. For example, in a bottom-exposure 3D printing device, the movement of the component plate causes the space between the component plate and the bottom of the resin tank and the first cured layer to be filled again with resin liquid to be cured. The energy radiation system then irradiates again to obtain a second cured layer attached to the first cured layer. This process is repeated, with multiple filling, irradiation, and separation operations accumulating the cured layers on the component plate to obtain a 3D object.

[0037] For ease of description and understanding, the following embodiments use a bottom-exposure 3D printing device as an example for illustration, and should not be construed as a limitation of this application.

[0038] Please see Figure 1 The image shown is a block diagram of a 3D printing device in one embodiment of this application, as follows: Figure 1 As shown, the 3D printing equipment includes a resin tank 1, an energy radiation system 2, a component mechanism 3, a Z-axis moving mechanism 4, and a control device 5.

[0039] In one embodiment, the resin tank 1 is used to hold liquid resin. The liquid resin is any easily photocurable liquid resin, including, for example, a simple photocurable resin liquid, or a photocurable resin liquid doped with powder materials, etc. The doped powder materials include, but are not limited to, ceramic powder or color additive powder. The material of the resin tank 1 includes, but is not limited to, glass, plastic, and resin. The capacity of the resin tank 1 depends on the type of 3D printing equipment. In some applications, the resin tank is also referred to as a container.

[0040] In one embodiment, the energy radiation system 2 is disposed at the bottom of the resin tank 1 and is used to irradiate the resin liquid in the resin tank 1 to obtain a patterned curing layer. Specifically, the energy radiation system 2 irradiates the resin liquid in the resin tank 1 with images of each layer from the printing data generated based on the cut 3D model of the pre-printed 3D object to obtain the 3D object. In some applications, the energy radiation system is also referred to as an optical system.

[0041] In one embodiment, the component mechanism 3 includes a component plate for attaching an irradiated and cured pattern layer to accumulate and form a three-dimensional object. Specifically, the component plate typically starts from a preset printing reference surface located within the resin tank 1, and accumulates each cured layer cured on the printing reference surface layer by layer to obtain the corresponding three-dimensional object. The printing reference surface refers to the starting surface where the resin liquid is irradiated.

[0042] In one embodiment, the Z-axis moving mechanism 4 is connected to the component mechanism 3 and is used to move in a controlled vertical direction to adjust the distance between the component plate and the printing reference surface and to fill the resin liquid to be cured. In order to accurately control the irradiation energy of each cured layer, the Z-axis drive mechanism needs to drive the component platform to move to the point where the distance between the component platform and the printing reference surface is minimized, which is the thickness of the cured layer to be cured.

[0043] In one embodiment, the Z-axis moving mechanism 4 may be configured to include a drive unit and a Z-axis moving unit. The drive unit drives the Z-axis moving unit so that the Z-axis moving unit drives the component mechanism 3 to move vertically. In one implementation, the drive unit is configured as a drive motor. Specifically, the drive unit may be controlled by control commands generated by the control device 5. In some examples, the control commands include directional commands indicating that the component mechanism 3 is rising, falling, or stopping. In other examples, the control commands may also include parameters such as rotational speed, acceleration, or torque to precisely control the moving distance of the Z-axis moving unit.

[0044] In one implementation, the Z-axis moving unit is configured to include a threaded rod associated with the driving unit in the vertical direction and moving guide rails disposed on both sides of the threaded rod. Correspondingly, the component mechanism 3 is provided with a slider connected to the moving guide rails and a nut structure connected to the threaded rod, so that the nut structure can be moved on the threaded rod under the drive of the driving unit, and the slider can be moved on the moving guide rails at the same time, thereby realizing the movement of the component mechanism 3 on the Z-axis moving mechanism 4.

[0045] In one embodiment, the control device 5 is connected to the energy radiation system 2 and the Z-axis movement mechanism 4, and is used to control the coordinated operation of the energy radiation system 2 and the Z-axis movement mechanism 4 to print three-dimensional objects. In one implementation, the control device 5 is an electronic device containing a processor, such as a computer device, an embedded device, or an integrated circuit with a CPU.

[0046] In one example, the control device includes a processing unit, a storage unit, and multiple interface units. Each interface unit is connected to an independently packaged device, component, or mechanism within the 3D printing equipment, such as the energy radiation system 2 and the Z-axis movement mechanism 4, and transmits data via the interface. The control device also includes at least one of the following: a prompting device, a human-computer interaction device, etc. The interface unit determines its interface type based on the connected device, component, or mechanism, including but not limited to: a universal serial interface, a video interface, an industrial control interface, and a wireless communication port. The storage unit stores the printing program, and the processing unit, connected to the storage unit, controls the various components or structures within the 3D printing equipment to coordinate the printing of the three-dimensional object when the printing program is executed.

[0047] Please see Figure 2 and Figure 3 The following are schematic diagrams of the component mechanism in one embodiment of this application, as shown below. Figure 2 and Figure 3 As shown, component mechanism 3 includes a mounting base 31 and a component device 32, wherein the component device 32 is detachably connected to the mounting base 31. Please refer to... Figure 4 This application is displayed as such. Figure 3 The illustrated embodiment shows a schematic diagram of the assembly and disassembly of the component device and the mounting base.

[0048] In one embodiment, such as Figure 2 As shown, the mounting base 31 is mounted on the Z-axis moving mechanism 4. In some examples, the mounting base 31 can be connected to the Z-axis moving mechanism 4 by a fixed connection method such as screwing or snap-fit, or by an integral molding connection method. For example, in an example where the Z-axis moving mechanism 4 is configured to include a threaded rod, the mounting base 31 can be configured to include a nut seat. The nut seat cooperates with the guide grooves on both sides and the guide rails on both sides of the threaded rod so that, under the drive of the drive unit, the rotation of the threaded rod drives the nut seat to move linearly upward or downward along the guide rails, thereby driving the mounting base 31 to move in the vertical direction.

[0049] Please see Figure 5 and combined Figure 3 and Figure 4 ,in, Figure 5 The diagram shown is a structural schematic of the mounting base in one embodiment of this application. Figure 5 As shown, the mounting base 31 includes a first mounting structure 311 and a rotating assembly 312, which is rotatable between a first position A and a second position B. The first position A refers to the position of the rotating assembly 312 when the component device 32 can be detached from the mounting base 31, as shown in the diagram. Figure 4 and Figure 5The position of the rotating component 312 is such that its axis is perpendicular to the surface of the mounting base 31. The second position B refers to the position of the rotating component 312 when the component device 32 is locked onto the mounting base 31, as shown in the image. Figure 2 and Figure 3 The rotating component 312 is positioned such that it is in contact with the surface of the mounting base 31. In one example, the rotation angle of the rotating component 312 between the first position A and the second position B is approximately 90°.

[0050] In one embodiment, such as Figure 5 As shown, the first mounting structure 311 is configured as a plate-like structure with a groove. The groove on the upper side of the plate-like structure is used to accommodate the rotating component 312 located at the second position B, as shown. Figure 3 As shown, when the rotating assembly 312 rotates to the second position B, the first mounting structure 311 is in contact with the rotating assembly 312. In this embodiment, as... Figure 5 As shown, the first mounting structure 311 has a first joint portion 3111, the specific function of which can be found in the description of the following embodiments.

[0051] Please see Figure 6 The diagram shows a schematic representation of the rotating component in one embodiment of this application. Figure 6 As shown, the rotating assembly 312 is configured to include a shaft assembly 313 and a handle structure 314. Please refer to... Figure 5 The shaft assembly 313 is disposed within the first mounting structure 311, and the handle structure 314 is rotatable about the shaft assembly 313 between the first position A and the second position B. In this example, the operator can rotate the handle structure 314 about the shaft assembly 313 by gripping it and applying force. For example, the handle structure 314 is located at... Figure 4 In the first position A shown, the operator can install the component device 32 onto the mounting base 31. After both are installed in place, the operator can hold the handle structure 314 and rotate it counterclockwise around the shaft assembly 313. Figure 3 The second position B, as shown, locks the component assembly 32 into the mounting base 31 for subsequent printing operations. After printing, the operator holds the handle structure 314 and rotates it clockwise around the shaft assembly 313. Figure 4 At position A as shown, the component device 32 is then removed from the mounting base 31.

[0052] Please see Figure 7 The diagram shown is a schematic representation of the handle structure in one embodiment of this application. Figure 7As shown, the handle structure 314 is configured to include a rod and a grip, which may be integrally formed, for example. Furthermore, the operator rotates the handle structure 314 by gripping the grip, and the shaft assembly 313 can pass through the rod and connect to the first mounting structure 311.

[0053] In one embodiment, such as Figure 7 As shown, the handle structure 314 is provided with an eccentric structure 3141, which causes the handle structure 314 to perform an eccentric motion when rotating around the shaft assembly 313. Figure 7 In the example shown, the eccentric structure 3141 has a first contact portion 31411 and a second contact portion 31412. The diameter of the second contact portion 31412 is larger than the diameter of the first contact portion 31411, and there is a smooth transition between the first contact portion 31411 and the second contact portion 31412. Specifically, the handle structure 314 rotates to... Figure 4 When in the first position A shown, the first contact portion 31411 contacts the component device 32; when rotated to Figure 3 In the second position B shown, the contact member device 32 is contacted via the second contact portion 31412, as described in the following embodiments. In one example, the eccentric structure 3141 is configured as a cam.

[0054] In one embodiment, such as Figure 6 As shown, the shaft assembly 313 is provided with a damping element 3131 for locking the handle structure 314 in the first position A or the second position B. In one implementation, the shaft assembly 313 is configured as a pin that passes through the handle structure 314, with both ends embedded in the first mounting structure 311 to connect the handle structure to the first mounting structure 311. Further, the damping element 3131 is sleeved on the shaft assembly 313 and located between the contact surfaces of the first mounting structure 311 and the handle structure 314 on one side. In this embodiment, the damping element 3131 increases the rotational resistance of the handle structure 314, providing damping force when the handle structure 314 is flipped so that the handle structure 314 can be continuously suspended at any angle between 5° and 85° between the first position A and the second position B. In some examples, the damping element 3131 is, for example, a damping pivot or a damping hinge, and the damping element 3131 includes a polytetrafluoroethylene or nylon gasket or a damping spring.

[0055] In other embodiments, the damping element 3131 of the damping shaft is, for example, a straight damping shaft, but it is not limited thereto. For example, the damping shaft can also be a gasket damping shaft, a die-cast damping shaft, a coiled damping shaft, and other damping shafts designed by those skilled in the art with similar structures or the same functions.

[0056] In one embodiment, such as Figure 6 As shown, a bushing 3132 is also provided on the shaft assembly 313. The bushing 3132 is embedded in the other side of the handle structure 314 so that the shaft assembly 313 can rotate around the bushing 3132, thereby reducing the friction generated when the handle structure 314 is directly mounted on the shaft assembly 313 and rotates.

[0057] In one embodiment, such as Figure 4 As shown, the component device 32 includes a component assembly 321 and a linkage assembly 322.

[0058] Please see Figure 8 The diagram shows a structural schematic of a component assembly in one embodiment of this application, as shown below. Figure 8 As shown, component assembly 321 includes component plate 3211 and second mounting structure 3212, wherein component plate 3211 is connected to second mounting structure 3212. The specific function of component plate 3211 can be found in the description of the foregoing embodiments, and will not be repeated here.

[0059] In one embodiment, the component plate 3211 and the second mounting structure 3212 can be fixedly connected by a fastener. In some examples, the fastener may be configured to include four fixing rods, one end of which is connected to the upper side of the component plate 3211 and the other end of which is connected to the lower side of the second mounting structure 3212.

[0060] In one embodiment, such as Figure 8 As shown, component assembly 321 also includes a leveling member 3213, through which component plate 3211 and second mounting structure 3212 are connected. In some examples, four leveling members 3213 are configured; the following description uses one leveling member 3213 as an example.

[0061] In one embodiment, the leveling member 3213 is configured as a rigid fixing rod connected between the component plate 3211 and the second mounting structure 3212, and a clamping member laterally disposed on the upper side of the rigid fixing rod for pressing against the rigid fixing rod. Specifically, when the clamping member presses against the rigid fixing rod, it forces the rigid fixing rod to move downward, thereby causing the component plate 3211 to make a fine adjustment in angle. Through the four leveling members 3213 disposed at different positions on the component plate 3211, four-point leveling of the component plate 3211 can be achieved.

[0062] In another embodiment, such as Figure 8 As shown, the leveling component 3213 is configured to be disposed in a housing (as shown in the figure). Figure 12The pressing part on the shown housing 320, and the elastic member connected between the member plate 3211 and the second mounting structure 3212. In this embodiment, the member plate 3211 is fixedly connected to the housing 320, and for specific details, reference can be made to the description in the subsequent embodiments. Specifically, the elastic member can assist in pressing the member plate 3211, and the pressing part can press the housing 320, forcing the housing 320 to move downward, thereby driving the member plate 3211 to perform fine adjustment in terms of angle. Through four leveling members 3213 provided at different positions of the member plate 3211, four-point leveling of the member plate 3211 can be achieved. In some examples, in order to fix the elastic member, the elastic member can be sleeved on the upper fixing rod and / or the lower fixing rod. The upper fixing rod is arranged vertically on the lower side of the second mounting structure 3212, and the lower fixing rod corresponds to the upper fixing rod and is fixed on the upper side of the member plate 3211.

[0063] Of course, in some other embodiments, the leveling members 3213 can be configured with other quantities, such as three, to achieve three-point leveling of the member plate 3211.

[0064] In one embodiment, as Figure 8 shown, the second mounting structure 3212 has a second engaging portion 3214. As described above, the first mounting structure 311 has a first engaging portion 3111. The second engaging portion 3214 can be inserted into the first engaging portion 3111 to connect the member device 32 to the mounting base 31. Specifically, please refer to Figure 4 , Figure 5 and Figure 8 . In these examples, the first mounting structure 311 is generally in a "П" - shaped structure, and the arms on the left and right sides of the "П" - shaped structure form the first engaging portion 3111. Correspondingly, the second mounting structure 3212 is generally in a "concave" - shaped structure, and the arms on the left and right sides of the "concave" - shaped structure form the second engaging portion 3214. During the process of inserting the second engaging portion 3214 into the first engaging portion 3111, the arms of the "П" - shaped structure and the "concave" - shaped structure can cooperate to form a guiding structure to guide the second mounting structure 3212 to move linearly until the second mounting structure 3212 is installed in place relative to the first mounting structure 311. After being installed in place, the handle structure 314 can be rotated to the second position B to lock the second mounting structure in the first mounting structure 311.

[0065] In one embodiment, as Figure 8 shown, the upper and lower sides of the second mounting structure 3212 are respectively formed with a first moving space 3215 and a second moving space 3216. In this example, the first moving space 3215 is formed in the concave portion of the "concave" - shaped structure of the second mounting structure 3212, and the second moving space 3216 is formed by enclosing the second mounting structure 3212, the leveling members 3213 and the member plate 3211.

[0066] Please see Figure 9 and Figure 10 ,in, Figure 9 This application is displayed. Figure 3 A cross-sectional schematic diagram of the component mechanism in the embodiment shown. Figure 10 This is a schematic diagram showing the linkage component installed in a second mounting structure in one embodiment of this application. Figure 9 and Figure 10 As shown, the linkage component 322 passes through the second mounting structure 3212. (As indicated...) Figure 10 As shown, the linkage component 322 includes a movable block 3221, which contacts the rotating component 312 to move downward when the rotating component 312 rotates to the second position B. As previously described, when the rotating component 312 is in the first position A, it contacts the movable block 3221 through the first contact portion 31411. When the rotating component 312 is in the second position B, it contacts the movable block 3221 through the second contact portion 31412. Since the diameter of the second contact portion 31412 is larger than the diameter of the first contact portion 31411, the movable block 3221 will move downward when the rotating component 312 rotates from the first position A to the second position B.

[0067] In one embodiment, such as Figure 10 As shown, the movable block 3221 includes a first part 3223 and a second part 3224. The first part 3223 passes through the second mounting structure 3212, and the second part 3224 is disposed at the lower end of the second mounting structure 3212. Figure 10 In the example shown, the movable block 3221 is configured as a convex block, with its upper portion forming a first part 3223 and its lower portion forming a second part 3224. Correspondingly, the second mounting structure 3212 has a hole structure for the first part 3223 to pass through. When the linkage assembly 322 passes through the second mounting structure 3212, the first part 3223 is located within the first movable space 3215 and the second mounting structure 3212, and the second part 3224 is located within the second movable space 3216.

[0068] In one embodiment, such as Figure 10As shown, the linkage component 322 also includes a force-applying component 3222. The force-applying component 3222 is connected to the second mounting structure 3212 and elastically contacts the second mounting structure 3212 when the movable block 3221 moves downwards, moving upwards to cooperate with the rotating component 312 to lock the component device 32 onto the mounting base 31. Further, the second part 3224 is used to contact the second mounting structure 3212, and the force-applying component 3222 is simultaneously fixedly connected to both the second mounting structure 3212 and the second part 3224. It should be understood that when the rotating component 312 rotates to the second position B, the movable block 3221 moves downward. At this time, the second part 3224 will trigger the force-applying component 3222 to provide a force, so that the second part 3224 moves upward. Since the second part 3224 is connected to the second mounting structure 3212 through the force-applying component 3222, the upward movement of the second part 3224 will drive the second mounting structure 3212 to move upward within the first movable space 3215, thereby causing the second mounting structure 3212 to press against the first mounting structure 311, thereby achieving the locking of the component device 32 and the mounting base 31.

[0069] exist Figure 8 In the illustrated embodiment, the force-applying components 3222 are configured in four groups. The structure of one group of force-applying components 3222 will be described in detail below. Please refer to... Figure 11 The image shown is a cross-sectional schematic diagram of the force-applying component installed on the second mounting structure in one embodiment of this application, as follows: Figure 11 As shown, the force-applying component 3222 is configured to include a force-applying element 3225 and an elastic element 3226. The force-applying element 3225 has a fixed end 32251 and a free end 32252, and the elastic element 3226 is sleeved between the fixed end 32251 and the free end 32252. In one example, the force-applying element 3225 is configured as a shoulder screw (or shoulder screw, stop screw, stop bolt, brake bolt, etc.), with its fixed end 32251 fixed within the second mounting structure 3212, and the elastic element 3226 is configured as a spring. In this example, when the rotating component 312 rotates from the first position A to the second position B, the movable block 3221 moves downward to compress the spring so that the elastic element 3226 provides an upward elastic force. This elastic force pushes the second part 3224 to drive the second mounting structure 3212 to move upward within the first movable space 3215, thereby causing the second mounting structure 3212 to press against the first mounting structure 311, thus achieving the locking of the component device 32 and the mounting base 31.

[0070] Please see Figure 12 This is a schematic diagram of the component mechanism in another embodiment of this application. Figure 12As shown, the component device 32 also includes a housing 320, which is disposed on the component plate 3211 and surrounds the second mounting structure 3212. When the component device 32 is locked to the mounting base 31, the top of the housing 320 is flush with the top of the first mounting structure 311. In this example, the housing 320 also has a clearance opening for accommodating the handle structure 314, so that when the handle structure 314 is rotated to the second position B, it can be inserted into the clearance opening, thereby making the upper surface of the handle structure 314 flush with the top of the housing 320 and the first mounting structure 311, thus reducing the space occupied by the handle structure 314.

[0071] In summary, the 3D printing equipment and its component mechanism provided in this application, by setting a detachable component device connected to the mounting base, allows the component plate to be removed along with the three-dimensional object, improving operational convenience. By setting a first connecting part in the first mounting structure of the mounting base and a second connecting part in the second mounting structure of the component device, the component device can be installed on the mounting base through the guiding action of the first and second connecting parts. By setting a rotatable rotating component in the mounting base, combined with a linkage component on the component device, the installation and disassembly of the component device can be completed without the need for additional tools, solely through the counterforce provided by the force-applying component in the linkage component, further improving operational convenience and ensuring efficient part removal and printing.
