[0026] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Therefore, in the whole text of this specification, the appearance of the phrases "in one embodiment", "in an embodiment", "in an embodiment" and similar words may (but not necessarily) relate to the same embodiment.

[0027] As described in the background technology, technicians use a scraper to manually separate the 3D object from the component platform, which not only wastes manpower but also has low efficiency in picking up. Therefore, the present application proposes a component platform, a 3D printing device, a method for picking up, a control device and a storage medium. During the printing operation, the component platform is driven by the Z-axis moving mechanism of the 3D printing device to move up and down in the Z-axis direction to attach the accumulated solidified layer on the component platform to obtain a 3D object. After printing is completed, when the component platform rises to a preset position, the component platform is controlled to move so that the 3D object falls off the component platform. In this way, after printing is completed, the 3D object can be automatically separated from the component platform without human intervention, thereby improving the efficiency of picking up.

[0028] In one embodiment, the 3D printing device described in the present application may be an SLA device, and the corresponding energy radiation device includes a laser emitter, a lens group located on the light path of the laser emitter, and a galvanometer group located on the light output side of the lens group. The laser emitter is controlled to adjust the energy of the output laser beam, for example, the laser emitter is controlled to emit a laser beam of preset power and stop emitting the laser beam, and for another example, the laser emitter is controlled to increase the power of the laser beam and reduce the power of the laser beam. The lens group is used to adjust the focal position of the laser beam, and the galvanometer group is used to control the laser beam to scan the two-dimensional space of the surface or bottom of the resin liquid, and the resin liquid scanned by the light beam is solidified into a corresponding pattern solidified layer.

[0029] In one embodiment, the 3D printing device described in the present application may be a DLP device, and the corresponding energy radiation device used is a projection device. For example, the projection device includes a DMD chip, a controller and a storage module. Among them, the storage module stores a layered image that layers the 3D object model. After receiving the control signal of the controller, the DMD chip irradiates the light source of each pixel on the corresponding layered image to the bottom surface or the surface of the resin liquid. Among them, the DMD chip looks like a small mirror, which is encapsulated in a closed space composed of metal and glass. In fact, this mirror is composed of hundreds of thousands or even millions of micromirrors, each of which represents a pixel, and the projected image is composed of these pixels. The DMD chip can be simply described as a semiconductor optical switch and micro-lens corresponding to the pixel point. The controller allows / disables each microchip to reflect light by controlling each optical switch in the DMD chip, thereby irradiating the corresponding layered image directly onto the resin liquid or irradiating the resin liquid through the transparent bottom of the resin tank, so that the resin liquid corresponding to the image shape is solidified to obtain a patterned solidified layer.

[0030] In one embodiment, the 3D printing device described in the present application may be an LCD (Liquid Crystal Display, liquid crystal surface light source curing) device, and the corresponding energy radiation device used is an LCD liquid crystal screen light source system. The LCD device includes an LCD liquid crystal screen located above or below the resin tank, and a light source arranged above or below the LCD liquid crystal screen. The control chip in the energy radiation device projects the layered image of the slice to be printed onto the printing surface through the LCD liquid crystal screen, and uses the pattern radiation surface provided by the LCD liquid crystal screen to cure the resin liquid in the resin tank into a cured layer of the corresponding pattern.

[0031] In one embodiment, the 3D printing device described in any of the above embodiments can print based on a top exposure method or a bottom exposure method. For ease of description and understanding, the following embodiments are described by taking a 3D printing device set as a top exposure 3D printing device as an example, which should not be understood as a limitation to the present application.

[0032] In some embodiments disclosed in the present application, a component platform is provided, which is suitable for a 3D printing device including a resin tank for containing resin liquid. Figures 1 to 3 , Figure 1 It is a schematic diagram showing a structure in which a component platform in one embodiment of the present application is configured in a 3D printing device and is in a preset position. Figure 2 It is a schematic diagram showing the structure of the connection between the component assembly of the component platform and the Z-axis connecting member of the Z-axis moving mechanism in one embodiment of the present application, Figure 3 Display as Figure 2 The schematic diagram of the disassembled structure of the illustrated embodiment shows that, as shown in the figure, the component platform 1 includes a component assembly 10 and a drive assembly 11 .

[0033] The component assembly 10 is arranged in the resin tank in a liftable manner, and is used to immerse in the resin liquid and move in the first direction to adhere and accumulate solidified layers layer by layer to form a 3D object during printing. The first direction is a vertical direction, that is, the first direction is the Z-axis direction of the 3D printing device. Figures 1 to 3The direction of the Z axis in the resin tank. In one example, before printing, the 3D printing device controls the component assembly 10 to descend along a first direction to enter the resin tank; during the printing process, the component assembly 10 continues to gradually descend along the first direction to adhere to the accumulated solidified layers layer by layer to form a 3D object; after printing is completed, the component assembly 10 rises along the first direction to a preset position to leave the resin liquid. The preset position refers to a position above the liquid surface of the resin tank, which may be a pre-set position at a specific height. For example, the preset position is the height position of the drive assembly, at which the drive assembly can dock with the component assembly by moving in two directions at most. As a preferred embodiment, the drive assembly can dock with the component assembly by moving in one direction.

[0034] In one embodiment, if Figure 2 and Figure 3 As shown, the component assembly 10 includes a first shaft assembly 100, a second shaft assembly 101 and a belt-type component plate 102. The first shaft assembly 100 and the second shaft assembly 101 are arranged at intervals, and the belt-type component plate 102 is sleeved on the first shaft assembly 100 and the second shaft assembly 101 and can move in a second direction. The second direction is the direction in which the first shaft assembly 100 and the second shaft assembly 101 are arranged at intervals, such as Figure 2 and Figure 3 The belt component plate 102 has a surface for attaching a 3D object. During printing, the belt component plate 102 remains stationary in the second direction, and the 3D object is formed on the surface of the belt component plate 102. For example, the 3D object is formed on the outer surface of the upper side of the belt component plate 102. After printing, the 3D object can follow the belt component plate 102 and cause the 3D object to separate from the belt component plate 102 when the belt component plate 102 turns. It should be noted that when the 3D printing device performs printing based on the bottom exposure method, the 3D object is formed on the outer surface of the lower side of the belt component plate 102.

[0035] Furthermore, the component assembly 10 further includes a main frame, and the main frame includes two main frame frames 1030 arranged opposite to each other, and the first shaft assembly 100 and the second shaft assembly 101 respectively span the two ends of the two main frame frames 1030. Figure 5 Combined with Figures 1 to 3 , Figure 5Shown is a schematic diagram of the structure of the main frame in one embodiment of the present application. As shown in the figure, a first through hole 10300 is opened on one end of each of the main frame 1030 for installing the first axis component 100, and a second through hole 10301 is opened on one end of each of the main frame 1030 for installing the second axis component 101. The two ends of the first axis component 100 are respectively inserted into the first through holes 10300 of the two main frame 1030, and the two ends of the second axis component 101 are respectively inserted into the second through holes 10301 of the two main frame 1030.

[0036] like Figure 3 As shown, the first through hole 10300 is approximately a circular through hole, and the second through hole 10301 is approximately a rectangular through hole. However, this is not limited to this. In other embodiments, the second through hole 10301 can also be configured as a circular through hole similar to the first through hole 10300, or the first through hole 10300 and the second through hole 10301 can also be other irregular shapes, or the shapes and sizes of the two can also be the same.

[0037] In one embodiment, the main frame further includes a transverse rod connected between two main frame frames, which is used to increase the strength of the main frame, thereby improving the stability of the component assembly. The number of the transverse rods can be one or two or more. In one example, the main frame includes four transverse rods, which are arranged on the main frame at intervals. For example, a transverse rod is arranged between the two groups of support assemblies described below.

[0038] like Figure 2 As shown, the band-type component plate 102 is sleeved on the first shaft assembly 100 and the second shaft assembly 101, and is located at the inner side of the two main body frames 1030. To ensure that the band-type component plate on the inner side of the two main body frames can both carry 3D objects and turn at the first shaft assembly, the band-type component plate is a thin plate made of a material with certain rigidity and certain flexibility. Specifically, the band-type component plate can be made of materials such as stainless steel, silicon-manganese spring steel. In some examples, the thickness of the band-type component plate can be set to 0.3mm to 1.5mm, for example, set to 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm etc.

[0039] In one embodiment, the belt-type component plate is configured as a steel belt with mesh holes. The mesh holes on the belt-type component plate are conducive to the resin liquid on the belt-type component plate flowing back to the resin tank through the mesh holes to achieve the recovery of the resin liquid. For example, when the belt-type component plate rises above the surface of the resin liquid, the resin liquid on the belt-type component plate can flow back to the resin tank through the mesh holes. The shape of the mesh holes can be set to any shape, for example, it can be set to be circular or square.

[0040] In one embodiment, the first shaft assembly includes a shaft body and bearing components located at both ends of the shaft body. In order to facilitate the distinction from the bearing component and shaft body of the second shaft assembly, the bearing component and shaft body of the first shaft assembly are respectively referred to as the first bearing component and the first shaft body, and the bearing component and shaft body of the second shaft assembly are respectively referred to as the second bearing component and the second shaft body. The first bearing component or the second bearing component is configured as two corresponding to the two ends of the shaft body, the two first bearing components are respectively fixed at one end of the two main body frames in a relative position so that the first shaft body spans between the two main body frames, and the two second bearing components are respectively fixed at the other end of the two main body frames in a relative position so that the second shaft body spans between the two main body frames.

[0041] In one embodiment, see Figure 3 Combined with Figure 2 and Figure 5 , the first bearing component (not marked) includes a bearing 1001 and a shaft seat 1002. In order to facilitate the distinction from the bearing component of the second shaft assembly, the bearing and the shaft seat in the first bearing component are respectively referred to as the first bearing and the first shaft seat, and the bearing and the shaft seat in the second bearing component are respectively referred to as the second bearing and the second shaft seat. The first shaft seat 1002 is inserted into the first through hole 10300 of the main frame 1030 and sleeved on the outer side of the first bearing 1001. The first shaft body 1000 is straddled in the first bearing 1001 of the two main frames 1030.

[0042] In some embodiments, see Figure 6 Combined with Figure 1 and Figure 3 , Figure 6 Display as Figure 3In the enlarged partial view of F1 in the illustrated embodiment, as shown in the figure, the second coupling portion 10000 for coupling with the drive assembly 11 is provided on both end surfaces of the first shaft body 1000. Further, in order to facilitate the coupling of the second coupling portion 10000 with the drive assembly 11, the end of the first shaft body 1000 passes through the main body frame 1030 so that the second coupling portion 10000 is located outside the main body frame 1030. In one example, the drive assembly 11 is coupled to the first shaft assembly 100 by snapping together, and the second coupling portion 10000 may be a structure including a groove and / or a protrusion for engaging with the drive assembly 11. For example, the second coupling portion 10000 is configured as Figure 6 In another example, the drive assembly is combined with the first shaft assembly by magnetic attraction, and the second combination part 10000 is a magnet. In another example, the drive assembly is combined with the first shaft assembly by friction contact, and the second combination part 10000 is a contact surface for the drive assembly to be pressed. Further, in this example, the second combination part 10000 can be made of a material with good wear resistance, for example, the second combination part 10000 is made of a metal material.

[0043] In one embodiment, if Figure 6 As shown, a protruding structure 10001 is provided on the outer surface of the first shaft body 1000. Figure 2 As shown, the belt-type component plate 102 is provided with a hole-shaped structure 1020 adapted to the protruding structure 10001, so that when the first shaft body 1000 is driven to rotate, the belt-type component plate 102 can be driven to move by the combination of the protruding structure 10001 and the hole-shaped structure 1020. In one example, the surface of the protruding structure 10001 is set as an arc surface, so that the contact between the belt-type component plate and the arc surface can avoid wear and damage to the belt-type component plate, thereby extending the service life of the belt-type component plate.

[0044] In one embodiment, see Figure 3 Combined with Figure 2 and Figure 5The second shaft assembly 101 includes a second shaft body 1010 and second bearing components located at both ends of the second shaft body 1010. The second bearing component includes a second bearing 1011 and a second shaft seat 1012. The second shaft seat 1012 is inserted into the second through hole 10301 of the main frame 1030 and sleeved on the outer side of the second bearing 1011. The second shaft body 1010 is straddled in the second bearing 1011 of the two main frames 1030. The belt component plate 102 moves along the second direction under the drive of the first shaft assembly 100, and then the belt component plate 102 moving in the second direction drives the second shaft body 1010 to rotate relative to the main frame 1030.

[0045] When the printing format required by the 3D printing device is large, the belt component plate in the component platform also needs to be set larger, and the thickness of the belt component plate is also thinner. In order to prevent the belt component plate from collapsing, a supporting mechanism is configured on the main frame, and the supporting mechanism is located at the bottom of the belt component plate for supporting the belt component plate.

[0046] In one embodiment, in order to provide good support for the entire belt-type component plate, the support mechanism is configured to include multiple groups of support components spaced between the first shaft component and the second shaft component. In one example, the support mechanism is configured to include four groups of support components. In other embodiments, the support mechanism may also include only one or two groups of support components.

[0047] See also Figure 2 , Figure 3 and Figure 7 , Figure 7 Display as Figure 3 The partial enlarged view of F2 in the illustrated embodiment, as shown in the figure, the support assembly includes a support rod 1040 and a second adjustment assembly. Correspondingly, for each group of support assemblies, a third through hole 10302 is respectively arranged on the two main body frames 1030, and the two ends of the support rod 1040 are respectively inserted into the third through holes 10302 on the two main body frames 1030. Specifically, the support rod 1040 includes a connecting portion located at both ends thereof and a supporting portion located between the two connecting portions, and the connecting portions at both ends are used to be correspondingly inserted into the third through holes 10302 on the two main body frames 1030, and the upper surface of the supporting portion is a flat surface for fitting with the inner surface of the upper side of the belt-type component plate 102 to support the belt-type component plate 102.

[0048] The second adjustment component is connected to the portion of the support rod 1040 extending from the third through hole 10302, and is used to adjust and position the horizontal height of the support rod 1040, that is, to adjust the height of the support rod 1040 in the first direction. In the case where there are processing errors in the components of the component assembly 10, for example, in the case where there are processing errors in the belt-type component plate 102 and / or the support rod 1040, the height of the support rod 1040 can be adjusted by the second adjustment component to make the support rod 1040 fit the inner surface of the upper side of the belt-type component plate 102 to support the belt-type component plate 102, thereby preventing the belt-type component plate 102 from collapsing due to being too thin and too large, thereby affecting the printing quality of the 3D object.

[0049] The second adjustment component includes a screw (not shown) and a screw mounting seat 1041. On the lower side of each of the third through holes 10302, a corresponding screw mounting seat 1041 is arranged on the main frame 1030. The screw passes through the screw mounting seat 1041 from the lower side of the screw mounting seat 1041, and the top of the screw is abutted against the support rod 1040. By adjusting the height of the screw passing through the screw mounting seat 1041 up and down, the upper surface of the support rod 1040 is made to fit the inner surface of the upper side of the belt component plate 102 to support the belt component plate 102.

[0050] The present application does not limit the specific structure of the support assembly, as long as it can play the role of supporting the belt-type component plate 102. In other embodiments, the support assembly may also include only a support rod or the second adjustment assembly in the support assembly may also be composed of a structure including an elastic member (compression spring), for example, the compression spring is connected to the support rod, and the upper surface of the support rod is made to fit the inner surface of the upper side of the belt-type component plate by adjusting the compression amount of the compression spring.

[0051] After long-term use, the belt-type component plate may deform and loosen, which will affect the printing quality of the 3D object, and the belt-type component plate may slip. In order to prevent the belt-type component plate from slipping and improve the printing quality of the 3D object, a tensioning mechanism is configured on the main frame. Figure 2 and Figure 3 Combined with Figure 5The tensioning mechanism 105 is connected to the second shaft assembly 101, and can be tensioned to push the second shaft assembly 101 to move in a direction away from the first shaft assembly 100, so that the belt-type component plate 102 is tensioned. In one embodiment, the number of the tensioning mechanism 105 is two groups, and the two groups of tensioning mechanisms 105 are relatively arranged on the two main body frames 1030. The tensioning mechanism 105 is inserted into the second through hole 10301 and connected to the second shaft assembly 101. By adjusting the tensioning mechanism 105, the tensioning mechanism 105 can push the second shaft assembly 101 connected thereto to move in a direction away from the first shaft assembly 100, so that the belt-type component plate 102 is tensioned.

[0052] In one embodiment, the tensioning mechanism includes a first adjustment component and an elastic connecting portion sleeved on the first adjustment component. Figure 3 Combined with Figure 2 The first adjustment component includes a connecting rod 1050, a fixing portion 1051 for positioning the connecting rod 1050 on the main frame, and an adjustment nut 1052 sleeved on the connecting rod 1050.

[0053] One end of the connecting rod 1050 is connected to the second shaft seat 1012 of the second shaft assembly 101. Figure 3 As shown, the first adjustment assembly includes two connecting rods 1050, and one end of each connecting rod 1050 is disposed in a groove of the second shaft seat 1012. In other embodiments, the number of the connecting rods 1050 may also be one or more.

[0054] The number of the elastic connection parts 1053 and the number of the adjusting nuts 1052 are the same as the number of the connecting rods 1050. Each elastic connection part 1053 is sleeved on a corresponding connecting rod 1050, and one end of the elastic connection part 1053 is connected to the second shaft seat 1012 of the second shaft assembly 101, and the other end is connected to the adjusting nut 1052. The elastic connection part 1053 is tightened by twisting the adjusting nut 1052, even if the elastic connection part 1053 is in a compressed state, so that the elastic connection part 1053 pushes the second shaft seat 1012 to move away from the first shaft assembly 100, so that the belt component plate 102 is tightened. The elastic connection part 1053 is, for example, a spring.

[0055] See also Figure 7 Combined with Figure 3The fixing portion 1051 corresponds to a fourth through hole 10510 for combining with the connecting rod 1050, and one end of the connecting rod 1050 close to the first axis assembly 100 is inserted into the fourth through hole 10510. When the fixing portion 1051 is arranged on the main frame 1030 by a fixing structure such as a snap-fit ​​structure or a screw locking structure, the connecting rod 1050 can be positioned on the main frame 1030.

[0056] It should be noted that the present application does not limit the specific structure of the tensioning mechanism, as long as the belt-type component plate can be tensioned. For example, the tensioning mechanism is an adjustable screw-type tensioning device.

[0057] In one embodiment, see Figure 3 Combined with Figure 1 , Figure 2 and Figure 5 As shown in the figure, the component platform 1 also includes a connecting shaft 106, which is connected across the ends of the two main body frames 1030 and is used to connect the component assembly 10 with the Z-axis moving mechanism of the 3D printing device, so that the component assembly 10 can move in the first direction driven by the Z-axis moving mechanism. In one example, the connecting shaft 106 is connected to the Z-axis moving mechanism by means of mounting members 107 inserted on both sides thereof, and the mounting member 107 includes a first mounting portion and a second mounting portion in a vertical direction. The first mounting portion is used to connect with the Z-axis moving mechanism, for example, the first mounting portion is connected to the Z-axis connecting member 71 of the Z-axis moving mechanism. The second mounting portion includes a fifth through hole 1070 for the connecting shaft 106 to pass through, and the connecting shaft 106 is fixed in the sixth through hole 10303 at the end of the main body frame 1030 after passing through the fifth through hole 1070.

[0058] The Z-axis connecting member 71 includes a connecting portion, and the connecting portion is configured as a frame arranged in a vertical direction. Further, in order to improve the stability of the Z-axis connecting member 71, so as to ensure that the component assembly 10 can be stably arranged on the Z-axis connecting member 71. In one embodiment, the connecting portion of the Z-axis connecting member 71 may further include a support rod 710 for supporting the frame.

[0059] In one embodiment, the component platform also includes a leveling component 108, which is connected to the main frame to adjust the overall level of the belt component plate 102. In other words, the leveling component 108 can adjust the angle between the belt component plate 102 as a whole and the first direction so that the belt component plate 102 as a whole remains perpendicular to the first direction.

[0060] like Figure 2 and Figure 3 As shown, the leveling assembly 108 includes a connecting crossbar 1080 and a cantilever 1081 fixedly connected to the connecting crossbar 1080 and the main body frame 1030, and the overall level of the belt-type component plate 102 is adjusted by adjusting the extension and contraction of the cantilever 1081. Specifically, one end of the two cantilevers 1081 is respectively connected to the two main body frames 1030, and the other ends of the two cantilevers 1081 are respectively connected to the two ends of the connecting crossbar 1080, and the connecting crossbar 1080 is transversely fixed on the Z-axis connecting member 71 of the Z-axis moving mechanism. By adjusting the extension and contraction of the cantilever 1081 on any side of the component assembly 10, the position of the component assembly 10 on that side relative to the other side in the first direction can be adjusted, and then the two sides of the component assembly 10 can be ensured to be in the same position in the first direction at any time, so as to ensure the overall level of the component assembly 10 and the belt-type component plate 102.

[0061] In one embodiment, the cantilever includes a screw rod and a screw-in rod with a threaded hole, one of the screw rod and the screw-in rod is connected to the main body frame, and the other is correspondingly connected to the connecting cross bar. In this way, the extension and retraction of the cantilever can be controlled by adjusting the screw-in depth of the screw rod in the screw-in rod. When the length of the cantilever needs to be extended, the screw-in depth of the screw rod in the screw-in rod is reduced, and when the length of the cantilever needs to be shortened, the screw-in depth of the screw rod in the screw-in rod is increased.

[0062] In other embodiments, the cantilever may also be an electric telescopic rod, etc., as long as it can be telescopically adjusted to adjust the overall level of the belt component plate.

[0063] Furthermore, the leveling assembly 108 also includes a first cantilever mounting seat 1082 fixed on the main frame 1030 and a second cantilever mounting seat 10800 fixed at both ends of the connecting cross bar 1080, and the first cantilever mounting seat 1082 and the second cantilever mounting seat 10800 are respectively connected to the two ends of the cantilever 1081 through a fixing structure such as screw locking.

[0064] See also Figure 4 Combined with Figure 1 , Figure 4 The schematic diagram of the disassembled structure of the driving assembly of the component platform in one embodiment of the present application is shown in the figure. As shown in the figure, the driving assembly 11 is arranged on at least one side of the resin tank, and is used to move in the third direction to combine with the first shaft assembly 100 of the component assembly 10 after leaving the resin liquid, so as to drive the first shaft assembly 100 to drive the belt-type component plate 102 to move in the second direction. The third direction is the direction in which the length of the first shaft assembly is located, and can also be understood as a direction perpendicular to the movement direction of the belt-type component plate 102, such as Figure 1 The direction of the Y axis in .

[0065] In one example, the drive assembly is provided in two groups, and the two groups of drive assemblies are relatively arranged on opposite sides of the resin tank. In another example, the drive assembly is provided in one group, and one group of drive assemblies is arranged on one side of the resin tank. It should be understood that being arranged on one side or both sides of the resin tank means being arranged at any spatial position on the side of the resin tank, including the upper part, the middle part, or the lower part of the side of the resin tank.

[0066] like Figure 1 As shown, the component platform 1 further includes a support frame 12 , which is disposed around the resin tank and is used to provide an installation space for the drive assembly 11 . Figure 1 The two groups of driving assemblies 11 shown are respectively arranged on opposite sides of the supporting frame 12, so that the two groups of driving assemblies 11 are located on opposite sides of the resin tank.

[0067] In one embodiment, see Figure 4 Combined with Figure 1 The driving assembly 11 includes a first driving part 110, and the first driving part 110 includes a first coupling part 1101 and a first motor 1100 connected to the first coupling part 1101. The first coupling part 1101 is used to couple with the first shaft assembly 100 so as to drive the first shaft assembly 100 to rotate under the drive of the first motor 1100. According to different coupling modes of the driving assembly 11 and the first shaft assembly 100, the first coupling part 1101 may be a structure including a groove and / or a protrusion matching with the second coupling part, or a magnet having a magnetic property opposite to that of the second coupling part, or a contact surface that can be pressed and contacted with the second coupling part.

[0068] In one embodiment, the driving assembly 11 further includes a second driving part 111, which is connected to the first driving part 110 and is used to drive the first driving part 110 to engage with or separate from the first shaft assembly 100. For example, after printing is completed and the component assembly rises to a preset position, the second driving part 111 drives the first driving part 110 to move toward the first shaft assembly 100 in the third direction to engage with the first shaft assembly 100, thereby driving the first shaft assembly 100 to drive the belt-type component plate 102 to move in the second direction. After the 3D object on the belt-type component plate 102 is separated, the second driving part 111 drives the first driving part 110 to move away from the first shaft assembly 100 in the third direction to separate from the first shaft assembly 100, thereby the component assembly 10 can descend along the first direction to enter the resin tank to start printing the 3D object.

[0069] In one embodiment, if Figure 1 and Figure 4 As shown, the second driving part 111 includes a second motor 1110 and a moving part connected to the second motor 1110, and the moving part is driven by the second motor 1110 to drive the first driving part 110 to move in a third direction to be combined with or separated from the first shaft assembly 100. In one example, the moving part includes a gear 1111, a rack 1112, a second motor seat 1113, a slide 1114, a guide rail 1115, and a guide rail mounting seat 1116. The second motor seat 1113 is fixedly arranged on the support frame 12, the second motor 1110 is arranged on the second motor seat 1113, the output shaft of the second motor 1110 is connected to the gear 1111, and the gear 1111 is meshed with the rack 1112. The rack 1112 includes a plurality of teeth for meshing with the gear 1111 on the side close to the second motor 1110. The rack 1112 is fixedly arranged on one side of the slide 1114, the slide 1114 is slidably arranged on two guide rails 1115, the two guide rails 1115 are symmetrically arranged on the guide rail mounting seat 1116, the guide rail mounting seat 1116 is fixedly arranged on the support frame 12, and the first driving unit 110 is fixedly arranged on the slide 1114. In this way, the second motor 1110 drives the gear 1111 to rotate and drive the rack 1112 to drive the slide 1114 to move on the guide rail 1115, thereby driving the first driving unit 110 to move in the third direction to be combined with or separated from the first shaft assembly 100.

[0070] It should be noted that the moving component is not limited to the structure described in the above embodiment, as long as it can drive the first driving part to move in the third direction under the drive of the second motor.

[0071] In one embodiment, if Figure 2 As shown, the component platform 1 further includes a scraper 13, which is arranged parallel to the distal end of the component assembly 10 and is attached to the turning area of ​​the belt component plate 102, wherein the distal end of the component assembly 10 is the end where the first shaft assembly 100 is located. The scraper 13 can clean the residue on the belt component plate 102. For example, the support of the 3D component is not easy to be separated from the belt component plate 102, and the scraper 13 can remove the residual support on the belt component plate 102. In an example, refer to Figure 8 Combined with Figure 1 and Figure 2 , Figure 8 Display as Figure 1A local enlarged view of F3 in the illustrated embodiment is shown in the figure, as shown in which the two sides of the scraper 13 are arranged at the ends of the two main frame frames 1030 in the component assembly 10 through the scraper mounting portion 14, and the blade of the scraper 13 is in contact with the turning area of ​​the belt component plate 102. Therefore, when the belt component plate 102 moves, the scraper 13 can remove the residue on the belt component plate 102 in the turning area of ​​the belt component plate 102.

[0072] The residue may include, for example, the support part of the 3D object. The turning of the belt-type component plate will cause the 3D object to detach. This detachment may be the separation of the support part from the 3D object. Thus, the support part remains on the belt-type component plate and can be cleaned by the scraper so as not to hinder the printing of the next object. Of course, the residue may also be other printing residues, etc. The scraper cleans the residue to ensure the cleanliness of the entire belt-type component plate.

[0073] In some embodiments disclosed in this application, a 3D printing device is proposed. Fig. 9 , which is a block diagram of a 3D printing device in one embodiment of the present application. As shown in the figure, the 3D printing device includes a component platform 4, a resin tank 5, an energy radiation device 6, a Z-axis moving mechanism 7, and a control device 8.

[0074] In one embodiment, the component platform 4 is configured as a component platform proposed in some embodiments of the present application, for details, please refer to Figures 1 to 8 And the related description will not be repeated here.

[0075] The resin tank 5 is used to hold the resin liquid. The Z-axis moving mechanism 7 is connected to the component platform 4 to control the movement of the component platform 4 on the Z-axis. The energy radiation device 6 is used to irradiate the resin liquid in the resin tank to obtain a solidified layer on the component platform 4. The control device 8 is connected to the energy radiation device 6, the Z-axis moving mechanism 7 and the component platform 4 to control the energy radiation device 6, the Z-axis moving mechanism 7 and the component platform 4 to work together to attach the accumulated solidified layer on the component platform 4 to obtain a 3D object and control the movement of the component platform 4 when the component platform 4 rises to a preset position so that the 3D object falls off the component platform. It should be noted that in certain embodiments of the present application, the Z-axis direction is referred to as the first direction.

[0076] In one embodiment, the capacity of the resin tank depends on the type of 3D printing device. Generally, since the printing format (or radiation format) of a 3D printing device based on SLA technology is larger than that of a 3D printing device based on DLP technology, the capacity of the resin tank in a printing device based on SLA technology is larger than that in a printing device based on DLP technology.

[0077] In one embodiment, the resin liquid contained in the resin tank may be a resin liquid doped with mixed materials such as additives, pigments, dyes, etc., or may be a resin liquid without any material added. The material of the resin tank includes but is not limited to: glass, plastic, resin, etc.

[0078] In one embodiment, the energy radiation device is used to irradiate the resin liquid in the resin tank so that a cumulative solidified layer is attached to the component platform. In one example, the energy radiation device irradiates the resin liquid in the resin tank according to the printing strategy of each layer in the printing data generated by the three-dimensional model to obtain a 3D object. In some scenarios, the energy radiation device can also be referred to as an optical system or an optical machine.

[0079] like Fig. 9 As shown, the Z-axis moving mechanism 7 is connected to the component platform 4 so as to be able to drive the component platform 4 to move up and down in the resin tank 5 to print the 3D object. Specifically, the Z-axis moving mechanism 7 is used to controllably move along the first direction to adjust the distance between the component platform 4 and the printing reference plane and fill the resin liquid to be cured. Wherein, the printing reference plane refers to the starting surface where the resin liquid is irradiated. In order to accurately control the irradiation energy of each cured layer, the Z-axis moving mechanism 7 needs to drive the component platform 4 to move to the point where the minimum distance between the component platform 4 and the printing reference plane is the thickness of the cured layer to be cured. Wherein, in the embodiment where the 3D printing device is an SLA device for top surface laser scanning, the preset printing reference plane is usually located at the liquid surface containing the resin liquid; in the embodiment where the 3D printing device is a DLP device for bottom surface exposure, the preset printing reference plane is usually located at the bottom surface of the resin tank, or at a certain height from the preset position of the bottom surface, such as a DLP device using CLIP technology.

[0080] The Z-axis moving mechanism 7 is capable of being connected to the component platform 4 to drive the component platform 4 to move in the first direction. In one embodiment, the Z-axis moving mechanism 7 also includes a Z-axis connecting member. The Z-axis connecting member may be the Z-axis connecting member 71 or the Z-axis connecting member 72 described above. For example, the component platform 4 is the component platform 1 described above, and the Z-axis connecting member is the Z-axis connecting member 71 described above. For another example, the component platform 4 is the component platform 2 or 3 described above, and the Z-axis connecting member is the Z-axis connecting member 72 described above.

[0081] Furthermore, the Z-axis moving mechanism may further include a driving component, and the Z-axis connecting member is connected to the driving component so as to be driven by the driving component to translate in the first direction. For example, the driving component includes a driving motor and a vertical moving component, wherein the vertical moving component is connected to the Z-axis connecting member, and the vertical moving component is driven by the driving motor to drive the Z-axis connecting member to move vertically. The vertical moving component is exemplified by an electric cylinder. Specifically, the driving motor is controlled by the control instruction of the control device to drive the vertical moving component to move. Among them, the control instruction includes: a directional instruction for indicating that the Z-axis connecting member rises, falls or stops, and may even include parameters such as speed / speed acceleration, or torque / torque. This is conducive to accurately controlling the rising distance of the Z-axis connecting member to achieve precise adjustment of the Z-axis connecting member.

[0082] During printing, the control device controls the component platform to immerse in the resin liquid in the resin tank and move in the first direction one by one to attach and accumulate solidified layers layer by layer to form a 3D object. After printing is completed, the control device controls the component platform to rise to a preset position, and the preset position refers to a position where the Z-axis moving mechanism moves the component platform out of the resin tank to a certain height and is separated from the resin liquid to be solidified. When the component platform rises to the preset position, the control device controls the component platform to move so that the 3D object falls off the component platform. For example, the motor connected to the control device for driving the component platform to move can be set at the same height as the preset position, so that the component platform can be driven by the drive motor at the preset position to produce an action to make the 3D object fall off.

[0083] In one embodiment, the control device is an electronic device including a processing device and a storage device. For example, the control device is a computer device, an embedded device, or an integrated circuit with a CPU.

[0084] The storage device includes a non-volatile memory and a system bus. The non-volatile memory is, for example, a solid state drive or a USB flash drive. The system bus is used to connect the non-volatile memory with the CPU, wherein the CPU can be integrated in the storage unit, or packaged separately from the storage unit and connected to the non-volatile memory through the system bus.

[0085] In some embodiments, the memory may include a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), etc. The memory is used to store programs (such as printing programs, pickup programs, calibration programs, etc.), and the processor executes the program after receiving the execution instruction.

[0086] In some embodiments, at least one program stored in the storage device can be used by the processing device to execute the retrieval method described in any embodiment of the present application.

The general-purpose processor can be a microprocessor or any conventional processor, etc.

[0089] In some embodiments, the processing device is used to execute the at least one program to execute and implement the pickup method described in any embodiment of the present application.

[0090] The control device also includes a plurality of interface units. Each of the interface units is respectively connected to devices that are independently packaged in the 3D printing device such as the energy radiation system and the Z-axis moving mechanism and transmit data through the interface. The control device also includes at least one of the following: a prompt device, a human-computer interaction device, etc. The interface unit determines its interface type according to the connected device, which includes but is not limited to: a universal serial interface, a video interface, an industrial control interface, etc.

[0091] For example, the interface unit includes: a USB interface, an HDMI interface and an RS232 interface, wherein there are multiple USB interfaces and RS232 interfaces, the USB interface can be connected to a human-computer interaction device, etc., the RS232 interface is connected to a detection device and a Z-axis moving mechanism, and the HDMI interface is connected to an energy radiation system (optical system). The storage unit is used to store files required for printing by a 3D printing device. The files include: program files and configuration files required for CPU operation, etc.

[0092] In one embodiment, in order to receive the 3D object that falls off from the component platform 4 , the 3D printing device further includes a receiving mechanism, wherein the receiving mechanism is adjacent to the component platform 4 and is used to receive the 3D object that falls off from the component platform 4 .

[0093] In one embodiment, the receiving mechanism includes a container and a bracket. The container is placed on a bracket for support, and is used to receive the 3D object shoveled off. In one embodiment, a mesh plate is placed obliquely in the container. When there are large hollow 3D objects, it is difficult to collect all the resin liquid only by the collection trough. At this time, the resin liquid that has not been completely collected can continue to flow down along the mesh plate. In one embodiment, the height of the bracket is adjustable, and can be adjusted to be flush with the component platform and docked with the component platform. In one embodiment, the bottom end of the bracket is also provided with a pulley that can facilitate horizontal movement, so as to move the position to be adjacent to the component platform.

[0094] In one embodiment, the receiving mechanism further includes an arrival detection sensor for detecting whether the receiving mechanism has reached the material receiving position.

[0095] For a specific example, see Figure 1 The component platform is 4 Figure 1 In the component platform 1 shown, the receiving mechanism 9 further comprises an inclined receiving plate 90. The upper position of the receiving plate 90 is located at the lower side of the turning point of the belt component plate 102, and the lower position of the receiving plate 90 is connected to the container 91. The receiving plate 90 is used to receive the 3D objects and / or residues that fall off at the turning point, and allows the 3D objects and / or residues to slide along the receiving plate 90 into the container 91 under the action of gravity.

[0096] The present application also provides a method for removing components, which is applied to a component platform including the aforementioned belt-type component plate (for example, Figures 1 to 8 The 3D printing device of the component platform shown in the figure can be used to print the 3D object attached to the belt-type component plate. The method of removing the object can be performed by the control device described above or other control devices that can perform the method of removing the object. After completing the 3D printing, the control device can control the component assembly and the drive assembly so that the 3D object attached to the belt-type component plate can be separated from the belt-type component plate.

[0097] See also Fig.10 , which is a flow chart of a pickup method in one embodiment of the present application. As shown in the figure, the pickup method includes steps S210 to S220.

[0098] In step S210, when the control device detects that the component assembly is located at a preset position, the control device controls the driving assembly to move to engage with the first shaft assembly.

[0099] The preset position refers to a position above the liquid level of the resin tank, which may be a position at a specific height set in advance. For example, the preset position is the height position of the drive assembly, at which the drive assembly can dock with the component assembly by moving in at most two directions. As a preferred embodiment, the drive assembly can dock with the component assembly by moving in one direction.

[0100] In one embodiment, when it is detected that the component assembly is located at a preset position, the control device controls the second driving part to operate so as to drive the first driving part to move in a third direction so as to be combined with the first shaft assembly.

[0101] In one embodiment, a distance sensor is provided on the driving assembly to determine whether the driving assembly is coupled with the first shaft assembly by detecting the distance between the first shaft assembly and the driving assembly. After the control device determines that the driving assembly is coupled with the first shaft assembly, the control device executes step S220.

[0102] In step S220, the control device controls the driving assembly to drive the first shaft assembly to rotate, so that the belt member plate moves.

[0103] In one embodiment, after the driving assembly is combined with the first shaft assembly, the first driving portion drives the first shaft assembly to rotate, so that the belt member plate moves in the second direction.

[0104] After the belt-type component plate travels a preset distance or when there is no 3D object and residue on the belt-type component plate, the control device controls the first driving part to stop driving. After the first driving part stops driving, the control device controls the second driving part to work to drive the first driving part to separate from the first axis assembly. Then, the control device can continue to control the Z-axis moving mechanism to move downward to adhere the accumulated solidified layers layer by layer on the component assembly to form a 3D object.

[0105] The present application also provides a control device, which is applicable to a 3D printing device including a component platform, and includes a storage device and a processing device, wherein the storage device stores at least one program, and the processing device is connected to the storage device for executing the at least one program to execute and implement the method for picking up the component described in any embodiment of the present application.
