Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] like Figure 1As shown, the container assembly 1 provided by the present invention includes: an outer cylinder 2 and an end cap 3.

[0041] like Figure 2 and Figure 4 As shown, in this embodiment, the bottom end of the outer cylinder 2 is provided with a light-transmitting component 4, the top end is provided with an opening 21, and the end cap 3 is connected to the top end of the outer cylinder 2.

[0042] The end cap 3 and the outer cylinder 2 can be connected by threads or by plugging to achieve the closure of the outer cylinder 2.

[0043] like Figure 3 As shown, in this embodiment, the end cap 3 and the outer cylinder 2 can be connected by a threaded connection, and the end cap 3 can be completely detached from the outer cylinder 2. In other possible solutions, the end cap 3 and the outer cylinder 2 can be connected by a snap-fit ​​connection; or, the end cap 3 can be rotatably connected to the outer cylinder 2, and the end cap 3 can be opened and closed in a flip-top manner, achieving the opening or closing of the end cap 3 by flipping it.

[0044] The end cap 3, the outer cylinder 2, and the light-transmitting component 4 form an inner cavity 22, which is used to seal and store the printing material, which can be resin. The container assembly 1 can be directly installed on the printer as the printing material box of the printing system. During printing, the end cap 3 is removed, and the printer's light source emits light. The light is projected into the interior of the outer cylinder 2 through the light-transmitting component 4 at the bottom of the outer cylinder 2. The platform assembly 5 of the printing system moves layer by layer in the inner cavity 22, and the printing material contained therein is formed layer by layer, adhering to the platform assembly 5 (first layer) or the previous layer, forming a 3D printed part adhered to the platform assembly 5. In other feasible solutions, the platform assembly 5 (for forming the printed part) can be part of the printer. The end cap 3 is operated to open the opening 21 of the outer cylinder 2, and the platform assembly 5 extends into the interior of the outer cylinder 2 to the forming station. The light source is turned on, and the light shines through the light-transmitting component 4 to the forming station. As the platform assembly 5 moves layer by layer, the printing material is formed layer by layer at the forming station, and a printed part is formed between the platform assembly 5 and the light-transmitting component 4.

[0045] like Figures 2-4 As shown, the outer cylinder 2 has a built-in platform component 5. Unlike the above scheme, in this embodiment, the platform component 5 is part of the container component 1, and the platform component 5 can also be enclosed inside the outer cylinder 2. The container component 1 is installed on the printer, and the operating end cover 3 opens the opening 21 of the outer cylinder 2, exposing the platform component 5. The printer's drive mechanism 6 is connected to the platform component 5, and printing can then begin.

[0046] The container component 1 can be disposable or reusable. In this embodiment, the container component 1 is preferably disposable, which can ensure the quality of the printing material, greatly improve the convenience of printing, avoid the occurrence of unstable printing quality, and the disposable container component 1 can be made with low-cost materials, which greatly reduces the manufacturing cost of the container component 1.

[0047] The container assembly is equipped with an axial limiting structure and a horizontal limiting structure to keep the platform assembly 5 confined inside the container assembly, preventing the platform assembly 5 from moving inside the container assembly, ensuring safety during transportation, and avoiding collision damage.

[0048] like Figure 3 and Figure 4 As shown, the outer cylinder 2 is provided with a limiting structure for the platform assembly 5 in the axial direction, so that when the platform assembly 5 is placed inside the outer cylinder 2, it will not extend too far in, so as to avoid squeezing the light-transmitting component 4.

[0049] Specifically, a limiting edge 51 is provided circumferentially on the platform component 5, and the limiting edge 51 is located at the upper end of the platform component 5. The end face of the opening 21 of the outer cylinder 2 forms an axial limiting structure. When most of the platform component 5 is inserted into the outer cylinder 2, since the inner diameter of the opening 21 is smaller than the outer diameter of the limiting edge 51, the limiting edge 51 overlaps at the end face of the opening 21 and cannot descend further, thus forming an axial limit. Furthermore, the outer diameter of the portion of the platform component 5 located inside the opening 21 is approximately equal to the inner diameter of the outer cylinder 2, and the inner wall of the outer cylinder plays a horizontal limiting role.

[0050] After the end cap 3 is connected to the outer cylinder 2, the limiting edge 51 is pressed between the end cap 3 and the end face where the opening 21 is located. The platform assembly 5 is stationary relative to the outer cylinder 2 to prevent the platform assembly 5 from shaking during transportation.

[0051] In other feasible solutions, a lock hole can be provided on the inner wall of the outer cylinder, and a lock tongue can be provided on the platform component 5. During transportation, the lock tongue is located in the lock hole, the platform component 5 is fixed relative to the outer cylinder 2, and the lock tongue needs to be manually pulled out from the lock hole by the user, thereby switching the platform component 5 to the working state.

[0052] like Figure 7As shown, the axial distance between the printing surface 55 of the platform component 5 and the light-transmitting component 4 is greater than or equal to 0. Preferably, the distance between the two is greater than 0 and greater than or equal to the stroke of the light-transmitting film 42 in the light-transmitting component 4 after it is stretched inward. That is to say, the container component 1 needs to be positioned and installed on the fixed table of the printing system. The fixed table has a transparent light-transmitting component 73 that supports the light-transmitting film 42. After the container component 1 is positioned, the transparent light-transmitting component 73 squeezes the light-transmitting film 42 into the outer cylinder 2, thereby putting it in a taut state. During the stretching process of the light-transmitting film 42, the distance between the light-transmitting film 42 and the printing surface 55 of the platform component 5 is greater than or equal to 0, so as to avoid the platform component 5 from squeezing and damaging the light-transmitting film 42.

[0053] like Figure 5 As shown, to facilitate increased printing adhesion, the platform component 5 has intaglio printing or through-holes, or both, on the side facing the light-transmitting component 4 (printing surface 55). This results in a larger contact area between the printed part and the printing surface 55, making separation less likely. After printing, the printed part can also be more easily removed during scraping.

[0054] Specifically, when the printing surface 55 has an intaglio printing, the intaglio printing includes a plurality of annular grooves 52 arranged sequentially from the inside to the outside; when the printing surface 55 has a through hole, the through hole includes a plurality of annular through holes arranged sequentially from the inside to the outside, and the printing material can enter the annular grooves 52 or the through holes. The intaglio printing or through holes arranged sequentially from the inside to the outside can further increase the connection area with the printed part and increase the connection strength.

[0055] The container assembly in this embodiment is used to print small-sized parts, such as teeth. Therefore, the required forming surface is small. The surface of the platform assembly 5 facing the light-transmitting assembly 4 can be circular, square, or even irregular in shape. When the surface is circular, its diameter is less than or equal to 75 mm; when the surface is square, its side length is less than or equal to 75 mm. Furthermore, when the surface is irregular in shape, it includes at least one complete circular area with a diameter less than or equal to 75 mm.

[0056] like Figure 3 and Figure 9As shown, the platform component 5 is provided with a connecting structure, which is used to connect with the driving component of the printing system. After the driving component and the platform component 5 are connected through the connecting structure, the platform component 5 can be driven to move up and down relative to the outer cylinder 2. Specifically, in one feasible connection scheme, the connecting structure may include a groove 54, and the driving component has a connecting part that connects to the groove 54. The connecting part is inserted into the groove 54, and the groove 54 and the connecting part are press-fitted, that is, the connecting part is directly pressed into the groove 54, and the two are tightly fitted. In another feasible scheme, the connecting structure may include a magnetic component, and a magnet is provided on the driving component to achieve connection by magnetic attraction. In yet another feasible scheme, the connecting part is provided with a vacuum suction hole to achieve connection of the platform component 5 by vacuum adsorption.

[0057] like Figure 3 As shown, the outer cylinder 2 is provided with a first light-transmitting hole; the light-transmitting component 4 includes a mounting cover 41 and a light-transmitting film 42. The mounting cover 41 is provided with a second light-transmitting hole, and the light-transmitting film 42 is located in the second light-transmitting hole. The mounting cover 41 is connected to the outer cylinder 2 to seal the light-transmitting film 42 in the first light-transmitting hole. Light enters the inner cavity 22 through the second light-transmitting hole, the light-transmitting film 42, and the first light-transmitting hole.

[0058] A first light-transmitting hole is provided in the middle area of ​​the bottom end of the outer cylinder 2, and the mounting cover 41 is fastened to the bottom end of the outer cylinder 2 with its side opening facing upwards. Furthermore, a second light-transmitting hole corresponding to the first light-transmitting hole is provided in the middle area of ​​the mounting cover 41. A light-transmitting film 42 is clamped between the bottom end of the outer cylinder 2 and the mounting cover 41, and the light-transmitting film 42 seals the first light-transmitting hole. Light enters the inner cavity 22 through the second light-transmitting hole, the light-transmitting film 42, and the first light-transmitting hole, and illuminates the printing surface 55 of the platform assembly 5.

[0059] In this embodiment, the light-transmitting film 42 is clamped and fixed between the outer cylinder 2 and the mounting cover 41. In other possible solutions, the light-transmitting film 42 can be first connected to the mounting cover 41 or the bottom end of the outer cylinder 2 (e.g., by adhesive), and then the mounting cover 41 can be connected to the outer cylinder 2. This ensures that the light-transmitting film 42 will not move when the mounting cover 41 is connected to the outer cylinder 2.

[0060] In other feasible solutions, the light-transmitting film 42 can be directly fixedly connected to the mounting cover 41 as an integral structure, without the need for the outer cylinder 2 to clamp the light-transmitting film 42 with the mounting cover 41. The light-transmitting film 42 can be directly fixed to the mounting cover 41 by means of clips or screws, etc.

[0061] In one feasible embodiment, the light-transmitting component 4 may further include a transparent support plate disposed below the light-transmitting membrane 42 and connected to the mounting cover 41. The transparent support plate supports and presses the light-transmitting membrane 42 into the inner side of the outer cylinder to taut the light-transmitting membrane 42.

[0062] The light-transmitting film 42 includes a release film, which can be a single-layer film or a multi-layer film. When it is a multi-layer film, it can include both a release film and a scattering film, or it can be both a release film and a leak-proof film.

[0063] like Figure 3 As shown, the mounting cover 41 is provided with a first concave-convex structure 43, and the outer cylinder 2 is provided with a second concave-convex structure 44. The first concave-convex structure 43 and the second concave-convex structure 44 have opposite concave-convex shapes and are interlocked with each other. The light-transmitting film 42 is sandwiched between the first concave-convex structure 43 and the second concave-convex structure 44. The light-transmitting film 42 is stretched and sealed between the first light-transmitting hole and the second light-transmitting hole to improve the flatness of the light-transmitting film 42.

[0064] A sealing ring 45 is provided between the mounting cover 41 and the outer cylinder 2 to improve the sealing performance.

[0065] The printing material capsule provided by the present invention includes the above-mentioned container assembly, wherein the inner cavity 22 of the container assembly contains printing material, which may be resin.

[0066] The printing material capsule assembly provided by the present invention includes a light-shielding structure and the container assembly described above; the light-shielding structure is connected to the container assembly, and the light-shielding structure blocks the light-transmitting component 4 to prevent external light from entering the inner cavity 22 through the light-transmitting component 4.

[0067] In one feasible embodiment, the light-shielding structure includes a light-shielding cover that is plugged into or threaded to one end of the container assembly having a light-transmitting component 4, thereby sealing the light-transmitting component 4 of a container assembly.

[0068] In another possible implementation, the light-shielding structure includes an openable and closable box with positioning slots inside. There can be multiple positioning slots to accommodate multiple container components. One end of each container component with a light-transmitting component 4 is inserted into the positioning slot. On the one hand, the bottom surface of the positioning slot seals the light-transmitting component 4. On the other hand, when the box is closed, the entire interior of the box is in a dark environment, further preventing light from entering the container components.

[0069] The bottom of the container assembly 1 is provided with an axial limiting mechanism that cooperates with the fixed seat 7 of the printing system to ensure that the outer cylinder 2 remains axially fixed relative to the fixed seat 7 during the process of the platform assembly rising.

[0070] like Figure 6 and Figure 10 As shown, the fixing base 7 is provided with a downwardly recessed positioning platform 71 for positioning the bottom of the container assembly 1 within the positioning platform 71. The inner diameter of the positioning platform 71 is consistent with the outer diameter of the bottom end of the container assembly 1, and the positioning platform 71 can serve as a circumferential limiting device. A vertical sliding groove 74 communicating with its top opening is provided on the circumferential inner sidewall of the positioning platform 71, and a transverse sliding groove 75 extending circumferentially is provided at the bottom end of the vertical sliding groove 74. A locking block 76 is provided on the container assembly 1, and the locking block 76 can slide along the vertical sliding groove 74 into the transverse sliding groove 75, while the transverse sliding groove 75 prevents the locking block 76 from moving vertically.

[0071] When assembling container assembly 1, the locking block 76 on container assembly 1 can be aligned with the vertical slide groove 74. Then, the lower container assembly 1 and the slider can move downwards along the vertical slide groove 74 into the horizontal slide groove 75. Then, the container assembly 1 can be rotated. After the locking block 76 moves into place along the horizontal slide groove 75, the horizontal slide groove 75 will limit the locking block 76 in the vertical direction. The container assembly 1 cannot move vertically relative to the fixed seat 7, thus ensuring the stability of the outer cylinder 2 when the platform assembly 5 rises.

[0072] In other feasible solutions, a buckle or pin structure can be installed on the fixing seat 7 to vertically limit the container assembly 1.

[0073] like Figure 8 As shown, the printing system provided by the present invention includes a fixing seat 7 for fixing the container assembly 1 described above.

[0074] The printing system also includes a mounting base 7, a light source, and a drive mechanism 6. The mounting base 7 is used to fix the container assembly 1, the light source emits light toward the light-transmitting assembly 4, and the drive mechanism 6 drives the platform assembly 5 to move up and down.

[0075] The printing system also includes a driver, one end of which is connected to the drive mechanism 6, and the other end of which is detachably connected to the platform assembly 5.

[0076] Before printing, open the end cap 3 of container component 1 and connect platform component 5 with the drive component, so that drive mechanism 6 drives platform component 5 to rise through the drive component.

[0077] The drive mechanism 6 and the drive components are detachably connected; there are multiple drive components, and at least two drive components are of different sizes to correspond to platform components 5 of different sizes.

[0078] For container components 1 of different sizes, different corresponding drive components can be replaced, so that the printing system can print different types of printed materials.

[0079] The connection between the driving component and the driving mechanism 6 can be magnetic or threaded, etc.

[0080] like Figure 8 and Figure 10 As shown, the fixing base 7 is provided with a downwardly recessed positioning platform 71, so that the bottom of the container assembly 1 is positioned and installed in the positioning platform 71. The inner diameter of the positioning platform 71 is consistent with the outer diameter of the bottom end of the container assembly 1, and the positioning platform 71 can play a circumferential limiting role.

[0081] The bottom of the positioning platform 71 is provided with a light-transmitting hole, and the edge of the light-transmitting hole is provided with an upwardly protruding annular support wall 72. A transparent light-transmitting element 73 is connected inside the annular support wall 72. The transparent light-transmitting element 73 is used to abut against the light-transmitting film 42 of the light-transmitting component 4 so that the light-transmitting film 42 is tightened.

[0082] like Figure 7 As shown, after the container assembly 1 is placed inside the positioning platform 71, the upwardly protruding transparent light-transmitting element 73 presses against the light-transmitting membrane 42 of the container assembly 1. After the compressed light-transmitting membrane 42 is tightened, it becomes flatter. Light enters the light-transmitting component 4 after passing through the light-transmitting hole and the transparent light-transmitting element 73. The tightened light-transmitting membrane 42 can make the light transmittance higher.

[0083] like Figure 6 and Figure 10 As shown, the positioning platform 71 has a vertical groove 74 on its inner circumferential sidewall that connects to its top opening. The bottom end of the vertical groove 74 has a horizontal groove 75 extending circumferentially. The container assembly 1 has a locking block 76 that can slide along the vertical groove 74 into the horizontal groove 75. The horizontal groove 75 prevents the locking block 76 from moving vertically.

[0084] When assembling container assembly 1, the locking block 76 on container assembly 1 can be aligned with the vertical slide groove 74. Then, the lower container assembly 1 and the slider can move downwards along the vertical slide groove 74 into the horizontal slide groove 75. Then, the container assembly 1 can be rotated. After the locking block 76 moves into place along the horizontal slide groove 75, the horizontal slide groove 75 will limit the locking block 76 in the vertical direction. The container assembly 1 cannot move vertically relative to the fixed seat 7, thus ensuring the stability of the outer cylinder 2 when the platform assembly 5 rises.
