Description

Technical Field

[0001] This utility model relates to the field of 3D printer technology, and in particular to a 3D printer that can automatically remove models. Background Technology

[0002] Currently, most I3 gantry-type fused deposition modeling (FDM) 3D printers lack multi-disc continuous printing capabilities. Multi-disc continuous printing effectively reduces the number of manual model removals during multi-disc printing, shortening the total printing time and significantly improving efficiency. Manually removing models from the 3D printing stage is time-consuming, labor-intensive, costly, and inconvenient. Furthermore, while some existing technologies can automatically remove models from the 3D printing stage for continuous printing, these primarily rely on the 3D print head impacting the model to remove it from the stage. However, this is difficult to achieve quickly with low-profile and small, thin models, requiring multiple cycles of impact demolding, resulting in low efficiency and inconvenience. Utility Model Content

[0003] The purpose of this invention is to provide a 3D printer that can automatically remove models, aiming to solve at least one of the technical problems existing in the prior art.

[0004] To achieve the above objectives, the present invention provides a 3D printer capable of automatically removing models, comprising:

[0005] Base;

[0006] Z-axis sliding module, the Z-axis sliding module is vertically arranged on the base;

[0007] An X-axis sliding module is mounted laterally on the Z-axis sliding module to drive the X-axis sliding module to slide up and down.

[0008] A 3D printing head is mounted on the X-axis sliding module to drive the 3D printing head to slide left and right via the X-axis sliding module;

[0009] Y-axis sliding module, wherein the Y-axis sliding module is mounted on the base;

[0010] A 3D printing platform is mounted on the Y-axis sliding module to drive the 3D printing platform to slide back and forth via the Y-axis sliding module.

[0011] A pusher plate is movably disposed at the bottom of the X-axis sliding module, and an elastic element is provided between the pusher plate and the X-axis sliding module.

[0012] In one possible implementation, the bottom of the X-axis sliding module is provided with a connecting hole, and the pusher plate is provided with a connecting post, which is movably inserted into the connecting hole.

[0013] In one possible implementation, there are multiple connecting holes, which are spaced apart along the length of the X-axis sliding module. The number of connecting posts is also multiple, and each connecting post is inserted into one of the multiple connecting holes. The pusher plate extends along the length of the X-axis sliding module.

[0014] In one possible implementation, the elastic element is sleeved on the connecting post, and the elastic element is used to apply a force to the pusher plate in a direction away from the X-axis sliding module.

[0015] In one possible implementation, the elastic element is a compression spring or a rubber ring.

[0016] In one possible implementation, a first ferromagnetic component is provided at the end of the connecting post, and a second ferromagnetic component is provided on the inner wall of the connecting hole, so that the pusher plate and the X-axis sliding module can be movably magnetically connected by the magnetic attraction of the first and second ferromagnetic components.

[0017] In one possible implementation, a scraper plate is provided at the front or bottom of the 3D printing stage.

[0018] In one possible implementation, both ends of the spatula are bent and extended toward the front end of the 3D printing stage to roughly form a C-shaped structure; and / or

[0019] The top of the pusher plate is bent and extended to form a folded edge, so as to be mounted on the bottom of the 3D printing table through the folded edge.

[0020] In one possible implementation, the pusher plate has an annular groove on one side facing the X-axis sliding module, the annular groove surrounds the connecting post, and the elastic element is partially housed within the annular groove.

[0021] In one possible implementation, a first groove is provided at the end of the connecting post, and the first ferromagnetic member is embedded in the first groove. A second groove is provided at the bottom of the connecting hole, and the second ferromagnetic member is embedded in the second groove.

[0022] As can be seen from the above technical solution, the 3D printer of this utility model with automatic model removal uses a 3D print head to print the model onto a 3D printing table. After the model is printed, the X-axis sliding module drives the 3D print head to slide to the left to its end. Then, the Z-axis sliding module drives the X-axis sliding module to slide downwards until the pusher plate presses against the 3D printing table and compresses the elastic element. Then, the Y-axis sliding module drives the 3D printing table to move backward, and the pusher plate slides along the surface of the 3D printing table until the pusher plate removes the printed model from the 3D printing table and pushes it onto the base. Finally, the Y-axis sliding module drives the 3D printing stage forward, and the front side of the 3D printing stage pushes the model on the base down to complete the automatic demolding or model removal, which is convenient for printing other models later. No manual model removal is required, saving time and effort, reducing costs, and enabling automatic continuous multiple printing. It is easy to use, and the pusher plate and elastic parts work together to ensure that the pusher plate can stick tightly to the surface of the 3D printing stage for pushing, which can effectively remove thin or small models that are stuck to the 3D printing stage. Model removal is quick, convenient, and efficient, providing a good user experience.

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Please refer to the following: Figures 1 to 9This embodiment provides a 3D printer capable of automatically removing models, including a base 100, a Z-axis sliding module 200, an X-axis sliding module 300, a 3D print head 310, a Y-axis sliding module, a 3D printing stage 400, and a pusher plate 330. The Z-axis sliding module 200 is vertically mounted on the base 100, and the X-axis sliding module 300 is horizontally mounted on the Z-axis sliding module 200, so that the X-axis sliding module 300 is driven to slide up and down by the Z-axis sliding module 200 for 3D printing. The head 310 is mounted on the X-axis sliding module 300 to drive the 3D printing head 310 to slide left and right. The Y-axis sliding module is mounted on the base 100. The 3D printing stage 400 is disposed on the Y-axis sliding module to drive the 3D printing stage 400 to slide back and forth. The pusher plate 330 is movably disposed at the bottom of the X-axis sliding module 300, and an elastic element 332 is disposed between the pusher plate 330 and the X-axis sliding module 300.

[0042] The base 100 is provided with a sliding groove 110. The Y-axis sliding module includes a first driving mechanism, which is located inside the base 100 and connected to the 3D printing stage 400 located above the base 100 via the sliding groove 110. The first driving mechanism drives the 3D printing stage 400 to slide back and forth along the sliding groove 110 on the base 100. The Z-axis sliding module 200 (partial structure not shown in the figure) includes a column and a second driving mechanism disposed within the column. The column is vertically disposed on the base 100, and the second driving mechanism is connected to the X-axis sliding module 300. The X-axis sliding module 300 is driven to move up and down along the column via a second drive mechanism. The X-axis sliding module 300 includes a crossbar, a drive motor 320, a first roller 351, a second roller 352, and a belt 340. The crossbar is movably mounted on the column. The drive motor 320 is fixedly connected to the crossbar. The first roller 351 and the second roller 352 are fixedly connected to both ends of the drive motor 320. The belt 340 is tightly wrapped around the crossbar and the shaft of the drive motor 320 via the first roller 351 and the second roller 352, and the belt 340 is movably mounted relative to the crossbar. The operation is configured such that the drive motor 320 rotates the shaft, driving the belt 340 to rotate around the crossbar. The 3D printing head 310 is movably mounted on the crossbar, and the 3D printing head 310 is connected to the belt 340 for transmission, so that the belt 340 drives the 3D printing head 310 to slide left and right on the crossbar. It should be noted that the Y-axis sliding module, X-axis sliding module 300, and Z-axis sliding module 200 mentioned above are all existing linear drive modules, which can be linear motor screw drive modules or linear motor belt drive modules. Their specific structures are described below. The principles and workings will not be elaborated upon here. For 3D printers, the specific structures and working principles of the Y-axis sliding module, X-axis sliding module 300, Z-axis sliding module 200 (some structural diagrams are not shown), and 3D printing head 310 are very common and conventional. Furthermore, these are not innovative inventions in this embodiment. Existing technologies can be used. For example, the specific structures of the Y-axis sliding module, X-axis sliding module 300, Z-axis sliding module 200, and 3D printing head 310 disclosed in Chinese Invention Patent Publication No. CN106915082A can be used. Therefore, they will not be elaborated upon here.

[0043] As can be seen, in this embodiment of the 3D printer capable of automatically removing the model, the 3D print head 310 prints the model onto the 3D printing table 400. After the model is printed, the X-axis sliding module 300 drives the 3D print head 310 to slide to the left to the end. Then, the Z-axis sliding module 200 drives the X-axis sliding module 300 to slide downwards until the pusher plate 330 presses against the 3D printing table 400 and compresses the elastic element 332. Then, the Y-axis sliding module drives the 3D printing table 400 to move backwards, and the pusher plate 330 slides along the surface of the 3D printing table 400 until the pusher plate 330 removes the printed model from the 3D printing table 400 and pushes it to the bottom. On the base 100, the final Y-axis sliding module drives the 3D printing stage 400 to move forward, and the front side of the 3D printing stage 400 pushes the model on the base 100 down to complete the automatic demolding or model removal, which is convenient for subsequent printing of other models. No manual model removal is required, saving time and effort, reducing costs, and enabling automatic continuous multiple printing. It is easy to use, and the pusher plate 330 and the elastic element 332 cooperate to make the pusher plate 330 stick tightly to the surface of the 3D printing stage 400 to push the material. It can effectively remove thin or small models that are stuck to the 3D printing stage 400. The model removal is fast, convenient, efficient, and provides a good user experience.

[0044] In this embodiment, the bottom of the X-axis sliding module 300 is provided with a connecting hole 334, and a connecting post 331 is provided on the pusher plate 330. The connecting post 331 is movably inserted into the connecting hole 334, and the elastic force of the elastic member 332 drives the pusher plate 330 to elastically and tightly fit the surface of the 3D printing stage 400, so as to push the thin or small model printed on the 3D printing stage 400 down. This design facilitates the removal of the 3D printed model and provides a good user experience.

[0045] Furthermore, there are multiple connecting holes 334, which are spaced apart along the length of the X-axis sliding module 300. Correspondingly, there are multiple connecting posts 331, each inserted into one of the connecting holes 334. The pusher plate 330 extends along the length of the X-axis sliding module 300. This arrangement makes the installation structure of the pusher plate 330 more stable and reliable. The pusher plate 330 can have an inclination angle, which makes it easier for the pusher plate 330 to lift and push the model 500 to be removed from the 3D printing table 400. The aforementioned multiple connecting holes 334 and multiple connecting posts 331 refer to two or more, and the pusher plate 330 can use one or more. This arrangement makes the connection structure between the pusher plate 330 and the X-axis sliding module 300 more stable, further improving the safety and reliability of the product and enhancing the user experience.

[0046] Furthermore, the elastic element 332 is sleeved on the connecting post 331, and the elastic element 332 is used to apply a force to the pusher plate 330 in a direction away from the X-axis sliding module 300, so that the elastic force of the elastic element 332 drives the pusher plate 330 to elastically fit with the surface of the 3D printing stage 400, so as to prevent the pusher plate 330 from fitting too tightly with the 3D printing stage 400 when removing the model 500 to be removed, thereby damaging or wearing down the 3D printing stage 400, and further improving the practicality and reliability of the product.

[0047] In this embodiment, the elastic element 332 is a rubber ring. Using a rubber ring is cost-effective and easy for the user to assemble. In other embodiments, the elastic element 332 can also be a spring; however, this embodiment does not limit this.

[0048] Furthermore, a first ferromagnetic component 333 is provided at the end of the connecting post 331, and a second ferromagnetic component 335 is provided on the inner wall of the connecting hole 334, so that the pusher plate 330 and the X-axis sliding module 300 can be movably magnetically connected by the magnetic attraction of the first ferromagnetic component 333 and the second ferromagnetic component 335. The first ferromagnetic component 333 and the second ferromagnetic component 335 are both magnets. The magnetic force of the magnets connects the pusher plate 330 to the X-axis sliding module 300. The connection method is simple, and no additional limiting structure is needed when the connecting post 331 is inserted into the connecting hole 334. The connecting post 331 can be easily moved in the connecting hole 334. Furthermore, under the elastic force of the rubber ring, when the connecting post 331 is inserted into the connecting hole 334, there is a certain gap between the end of the connecting post 331 and the bottom of the connecting hole 334. This prevents the pusher plate 330 from sticking too tightly to the 3D printing table 400 when removing the model 500, thus preventing damage to the 3D printing table 400. The magnetic connection method also prevents the pusher plate 330 from falling off, further improving the practicality and reliability of the product.

[0049] Furthermore, a scraper plate 410 is provided at the front end or bottom of the 3D printing stage 400. The scraper plate 410 is used to push the model 500 to be removed onto the base 100 when the pusher plate 330 pushes it down. The scraper plate 410 is driven forward by the Y-axis sliding module to push the model 500 to be removed off the base 100. Its structure is simple, easy to use, and has a good removal effect for the model 500, resulting in a good user experience.

[0050] In this embodiment, the top of the pusher plate 330 is bent and extended to form a folded edge 411, so that it can be installed on the bottom of the 3D printing table 400 through the folded edge 411. With this setting, the models to be removed 500 can be pushed to the same position in a concentrated manner, preventing the models pushed off the base 100 from scattering, making it convenient for users to clean up and organize, and providing a good user experience.

[0051] In other embodiments, both ends of the shovel plate 410 are bent and extended toward the front end of the 3D printing table 400 to roughly form a C-shaped structure. This arrangement can concentrate the models 500 to be removed to the same position, preventing the models that are pushed off the base 100 from scattering, making it convenient for users to clean up and tidy up, and providing a good user experience.

[0052] Furthermore, the pusher plate 330 has an annular groove on the side facing the X-axis sliding module 300, and the annular groove surrounds the connecting post 331, with the elastic element 332 partially accommodated within the annular groove. This design prevents the elastic element 332 from swaying freely on the connecting post 331, thus preventing it from affecting the insertion of the pusher plate 330 into the X-axis sliding module 300, further improving the reliability and practicality of the shovel and making it convenient for users.

[0053] Furthermore, a first groove is provided at the end of the connecting post 331, and the first ferromagnetic component 333 is embedded in the first groove. A second groove is provided at the bottom of the connecting hole 334, and the second ferromagnetic component 335 is embedded in the second groove. This arrangement makes it easier to install the first ferromagnetic component 333 and the second ferromagnetic component 335, resulting in a simple structure, stable and reliable operation, and a good user experience.

[0054] In this embodiment, the 3D printing head 310 prints the model onto the 3D printing table 400. After the model is printed, the drive motor 320 drives the 3D printing head 310 to slide to the left to its end. Then, the second drive mechanism of the Z-axis sliding module 200 drives the X-axis sliding module 300 to slide downwards until the pusher plate 330 presses against the 3D printing table 400 and compresses the elastic element 332. Then, the first drive mechanism of the Y-axis sliding module drives the 3D printing table 400 to move backwards. The tilt angle of the pusher plate 330 slides along the surface of the 3D printing table 400 until the pusher plate 330 removes the printed model from the 3D printing table 400 and pushes it onto the base 100. Finally... The first drive mechanism of the Y-axis sliding module drives the 3D printing table 400 to move forward, and the scraper plate 410 on the front side of the 3D printing table 400 pushes the model on the base 100 down to complete the automatic demolding or model removal, which is convenient for subsequent printing of other models. No manual model removal is required, saving time and effort, reducing costs, and enabling automatic continuous multiple printing. It is easy to use, and the pusher plate 330 and the elastic element 332 cooperate to make the pusher plate 330 stick tightly to the surface of the 3D printing table 400 to push the material. It can effectively remove thin or small models that are stuck to the 3D printing table 400. The model removal is fast, convenient, efficient, and provides a good user experience.

[0055] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0056] In this embodiment, the 3D printer with automatic model removal capability removes the model by having the pusher plate 330 press against the 3D printing table 400, pushing the printed model off the 3D printing table 400 onto the base 100. The scraper plate 410 on the front side of the 3D printing table 400 then pushes the model off the base 100 to complete the automatic demolding or model removal. This facilitates the subsequent printing of other models without the need for manual model removal, saving time and effort, reducing costs, enabling automatic continuous multiple printing, and providing a convenient, fast, and efficient model removal process with a good user experience.
