Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a 3D printing automatic whole-plate unloading device. Background Art

[0002] 3D printing is a device that plays a key role in the 3D printing process. In the field of 3D printing technology, it specifically involves a 3D printing automatic full-plate unloading device. A 3D printer has a printing platform (also called a building platform or print bed), which is where the model is supported and built during the printing process. During the printing process, the printing material (such as plastic, metal, ceramic, etc.) is accumulated layer by layer on the printing platform to build the final 3D model.

[0003] In some cases, especially in 3D printers using Fused Deposition Modeling (FDM) technology, after printing is completed, the model may still adhere to the base plate of the print bed. In order to remove the model from the base plate, it may be necessary to use tools such as knives and spatulas to carefully peel or cut off the connection between them, but this operation will prevent continued printing and affect printing efficiency. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a 3D printing automatic whole-plate unloading device, which can automatically remove the printed product and solidify it, avoiding affecting the subsequent printing operation, so as to solve the problems raised in the above-mentioned background technology.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a 3D printing automatic whole-plate unloading device of the utility model comprises a printing platform 1 and a rotating ring 4, wherein an arc groove 2 is provided on the printing platform 1, and a connecting groove 12 with an arc structure is provided on the bottom surface of the arc groove 2, and the rotating ring 4 is movably arranged in the connecting groove 12, and a plurality of placement plates 5 are installed in an annular structure on the top surface of the rotating ring 4, wherein one placement plate 5 is arranged inside the arc groove 2, an L-shaped plate 7 is installed on the bottom surface of the printing platform 1, and one end of the L-shaped plate 7 away from the printing platform 1 is bent upward, and a bearing plate 10 is installed, and a driving mechanism for driving the rotating ring 4 to rotate is installed on the inner ring surface of the rotating ring 4.

[0022] In this embodiment, the driving mechanism includes a reduction motor 9 and a driving wheel 8. The driving wheel 8 is installed on the rotating shaft of the reduction motor 9. The outer ring surface of the driving wheel 8 is set to abut against the inner ring surface of the rotating ring. The top surface of the driving wheel 8 is set lower than the bottom surface of the arc groove 2. A fixed plate is installed between the reduction motor 9 and the L-shaped plate 7. A controller for controlling the start and stop of the reduction motor is installed on the printing platform.

[0023] In this embodiment, a plurality of ball grooves are provided on the bearing plate 10, and balls 11 are movably installed in the ball grooves. Parts of the balls 11 extend to the outside along the openings of the ball grooves and are in contact with the bottom surface of the rotating ring 4.

[0024] Among them, the ball bearings can reduce the friction between the supporting plate and the rotating ring, so that the rotating ring can be driven to rotate more conveniently. Among them, the supporting plate can balance the two ends of the rotating ring to avoid the rotating ring tilting to one side. Among them, after the placement plate enters the interior of the arc groove, the rotating plate can be limited by the sliding connection between the positioning part and the positioning groove to avoid the rotating plate from tilting.

[0025] In this embodiment, arc-shaped positioning grooves 3 are provided on both sides of the arc groove 2, and arc-shaped positioning portions 6 are protruded on both sides of the placement plate 5. The positioning portions 6 on the placement plate 5 located inside the arc groove 2 are slidably set in the positioning grooves 3.

[0026] In this embodiment, slots are provided on the bottom surface of the placement plate 5, and a plurality of inserting parts are protruded on the top surface of the rotating ring 4. The inserting parts are inserted into the slots. The placement plate can be positioned by plugging, and the plugging facilitates the disassembly and installation of the placement plate.

[0027] In this embodiment, the rotating ring 4 is made of stainless steel, which increases firmness and prevents rust.

[0028] When the 3D printer is printing, the product can solidify on the placement plate inside the printing platform. After the product is printed, the reduction motor can be started. The start of the reduction motor drives the driving wheel. The rotation of the driving wheel drives the rotating ring through friction. The rotation of the rotating ring drives the inserting part. The placement plate can be pushed through the inserting part, so that the placement plate located inside the arc groove together with the product is moved out from the inside of the printing platform and moved to one side for cooling and solidification, while the other placement plate can automatically enter the arc groove, and the positioning parts on both sides of the placement plate are inserted into the positioning groove, so as to position the placed plate that has entered;

[0029] Among them, after the placement plate is moved out of the positioning groove, the placement plate will lose its limiting function, so that the placement plate can be directly removed from the rotating ring upwards, which facilitates the entire disassembly of the placement plate and can move the products on the placement plate for subsequent processing of the products.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
