[0002] A 3D printer, also known as a three-dimensional printer, is a type of additive manufacturing technology, or rapid prototyping technology. It uses a digital model file as a basis and employs special waxes, powdered metals, or plastics—materials that can be bonded together—to create three-dimensional objects by printing layer by layer. Currently, 3D printers are used to manufacture products. It's a technology that constructs objects by printing layer by layer. The principle of a 3D printer is that data and materials are put into the printer, and the machine will build the product layer by layer according to the program.

When the model is large and the external support material is also large and numerous, manual removal is laborious and inefficient. To solve the above problems, it is necessary to provide a 3D printed model support material removal device that is easy to use and flexible. Utility Model Content

[0004] This invention provides a 3D printing model support material removal device, which aims to solve the problem that after 3D printing, some support material is generated on the bottom and outside of the model, which needs to be removed to fully reveal the model. When the model is large and the external support material is also large and numerous, manual removal is laborious and inefficient.

[0010] Preferably, the top of the placement platform is provided with a built-in annular groove, and the inner wall of the built-in annular groove is provided with several positioning suction cups arranged in a ring.

[0011] Preferably, the positioning suction cup includes an electric suction cup, and a fine-tuning hydraulic cylinder is provided between the electric suction cup and the built-in annular groove.

[0014] Preferably, the bottom of both the first slide and the second slide is provided with a limiting slider, and the bottom of the first slide and the second slide are slidably connected to the inner wall of the main slide through the limiting slider.

[0015] Compared with the prior art, the embodiments of this application have the following main advantages:

[0016] Through the coordinated operation of the end fixing seat, the distance adjustment mechanism, the main slide, the first telescopic hydraulic cylinder, the first slide, the second telescopic hydraulic cylinder, the second slide, the storage component, the stabilizing component, and the removal component, efficient, stable, and automated removal of support material from 3D printed models is achieved. The end fixing seat, as the basic support of the overall structure, works with the main slide and the hydraulic cylinder to drive the slide to move, realizing multi-directional distance adjustment between the removal component and the model. The distance adjustment mechanism further refines the horizontal displacement of the robotic arm and improves positioning accuracy. The removal component achieves precise gripping and peeling through the mechanical claw, significantly improving removal efficiency and reducing manual operation intensity.

[0017] By configuring the storage components and driving the placement stage to rotate via a directional motor, the model's surface to be removed is displayed from multiple angles. Combined with the positioning suction cup in the built-in annular groove and its fine-tuning hydraulic cylinder structure, the model is quickly adsorbed and firmly fixed, preventing displacement or damage during removal. This component not only improves the model's positioning accuracy and operational flexibility but also significantly enhances the controllability and adaptability of the overall removal process. It is particularly suitable for models with complex structures or multi-directional outward supports, effectively improving removal efficiency and finished product quality.

[0018] By incorporating stabilizing components, a rotary motor drives the rotating frame and its stabilizing mechanism to rotate, allowing the curved plate and inner support rods to flexibly limit and support the model from the side. The rubber-coated support rods provide stable clamping while preventing scratches or indentations on the model surface. They are particularly effective at suppressing model swaying during the mechanical gripper's tearing operation, ensuring the smoothness and reliability of the support material removal process, further protecting model integrity and improving the removal success rate.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a 3D printing model support material removal device, including an end fixing seat 10: the outer wall of the end fixing seat 10 is provided with an adjustment mechanism 9, a main slide rail 1 is fixedly connected to one side of the end fixing seat 10, a first telescopic hydraulic cylinder 5 is fixedly connected to the outer wall of the end fixing seat 10, a first slide table 7 is fixedly connected to one end of the first telescopic hydraulic cylinder 5, a second telescopic hydraulic cylinder 6 is fixedly connected to the outer wall of the end fixing seat 10, and a second slide table 8 is fixedly connected to one end of the second telescopic hydraulic cylinder 6.

[0028] The second slide 8 is provided with a storage component 3 on its top, the first slide 7 is provided with a stabilizing component 4 on its top, and the end fixing seat 10 is provided with a removal component 2 on its top.

[0029] The removal component 2 includes a slide 201 that is fitted and slidably disposed on the inner wall of the end fixing seat 10. A straight rack is fixedly connected to the bottom outer side of the slide 201, and a robotic arm 202 is fixedly connected to the top of the slide 201. A robotic claw 203 is connected to the output end of the robotic arm 202.

[0030] The pitch adjustment mechanism 9 includes a pitch adjustment motor fixedly mounted on the outer wall of the end fixing seat 10. The output shaft of the pitch adjustment motor is fixedly connected to a pitch adjustment gear via a coupling. The outer wall of the pitch adjustment gear meshes with the bottom of the spur rack.

[0031] The bottom of the first slide 7 and the second slide 8 are both provided with limit sliders, and the bottom of the first slide 7 and the second slide 8 are slidably connected to the inner wall of the main slide 1 through the limit sliders.

[0032] It should be noted that in existing 3D printing, some support material is generated at the bottom and outside of the model. This material needs to be removed to fully reveal the model. When the model is large, the external support material is also numerous and large, making manual removal laborious and inefficient.

[0033] Specifically, in this embodiment, the solution mainly utilizes the setup and coordinated use of the end fixing seat 10, the adjusting mechanism 9, the main slide rail 1, the first telescopic hydraulic cylinder 5, the first slide table 7, the second telescopic hydraulic cylinder 6, the second slide table 8, the storage component 3, the stabilizing component 4, and the removal component 2. In use, firstly, the 3D printed model with the support material to be removed is placed on the placement platform 302, and the electric suction cup is activated and controlled to adsorb and fix the support plate of the bottom 3D printed model, thereby fixing the position of the 3D printed model on the placement platform 302. Then, the second telescopic hydraulic cylinder 6 is activated and controlled to adjust the placement platform 302. The distance between the 3D printed model on 02 and the removal component 2 is adjusted so that the removal component 2 can perform the peeling and removal operation. Then, the first telescopic hydraulic cylinder 5 is controlled to pull the first slide 7 so that the stabilizing component 4 is close to the 3D printed model. Then, the rotary motor 401 is controlled to drive the stabilizing mechanism 404 on the rotating frame 403 to rotate. The several inner support short rods 4042 set in the stabilizing mechanism 404 have a good limiting effect on the front and rear sides of the 3D printed model and work in conjunction with the positioning suction cup 303 at the bottom of the 3D printed model to provide a stable state in the subsequent support material peeling and removal step, ensuring that the support material is removed smoothly.

[0034] After the 3D printed model is fixed in place by the stabilizing component 4 and the storage component 3, the robotic arm 202 is controlled to flexibly adjust the position of the robotic claw 203 so that the robotic claw 203 can accurately grasp the support material on the outside of the 3D printed model and gently pull and break off the support material to complete the support material peeling and removal operation. The adjustable pitch motor is started and controlled to rotate and move the rack through the adjustable pitch gear, which drives the slide 201 to slide along the inner wall of the end fixing seat 10 to adjust the position of the robotic arm 202 and the robotic claw 203 to continue the removal operation.

[0035] After the support material on one side of the 3D printed model is removed, the first telescopic hydraulic cylinder 5 and the second telescopic hydraulic cylinder 6 are controlled to disperse the storage component 3 and the stabilizing component 4. The directional motor 301 is controlled to adjust the surface of the 3D printed model to be removed of support material as needed. The above operation is repeated to continue the removal of support material.

[0036] In this embodiment, through the coordinated operation of the end fixing seat 10, the distance adjustment mechanism 9, the main slide rail 1, the first telescopic hydraulic cylinder 5, the first slide table 7, the second telescopic hydraulic cylinder 6, the second slide table 8, the storage component 3, the stabilizing component 4, and the removal component 2, efficient, stable, and automated removal of the support material of the 3D printed model is achieved. The end fixing seat 10 serves as the basic support of the overall structure, and works with the main slide rail 1 and the hydraulic cylinder to drive the slide table to move, realizing multi-directional distance adjustment between the removal component 2 and the model. The distance adjustment mechanism 9 further refines the horizontal displacement of the robotic arm 202 and improves the positioning accuracy. The removal component 2 achieves precise gripping and peeling through the mechanical claw 203, which significantly improves the removal efficiency and reduces the intensity of manual operation. It is particularly suitable for the post-processing of large-volume, multi-support structure models and has good practicality and promotion value.

[0037] In a further preferred embodiment of the present invention, the storage component 3 includes a directional motor 301 fixedly mounted on the second slide table 8. The output shaft of the directional motor 301 is fixedly connected to a rotating shaft via a coupling, and one end of the rotating shaft is fixedly connected to the placement platform 302.

[0038] The top of the placement platform 302 is provided with a built-in annular groove, and several positioning suction cups 303 are arranged in a ring on the inner wall of the built-in annular groove.

[0039] The positioning suction cup 303 includes an electric suction cup, and a fine-tuning hydraulic cylinder is provided between the electric suction cup and the built-in annular groove.

[0040] In this embodiment, by setting up the storage component 3, the placement stage 302 is rotated by the directional motor 301, allowing the model to be displayed from multiple angles to the surface to be removed. Combined with the positioning suction cup 303 in the built-in annular groove and its fine-tuning hydraulic cylinder structure, the model is quickly adsorbed and firmly fixed, preventing displacement or damage during removal. This component not only improves the model's positioning accuracy and operational flexibility but also significantly enhances the controllability and adaptability of the overall removal process. It is particularly suitable for models with complex structures or multi-directional outward supports, effectively improving removal efficiency and finished product quality.

[0041] In a further preferred embodiment of the present invention, the stabilizing component 4 includes a rotary motor 401 fixedly mounted on the first slide table 7. The output shaft of the rotary motor 401 is fixedly connected to a rotating rod 402 via a coupling. One end of the rotating rod 402 is fixedly connected to a rotating frame 403. Several stabilizing mechanisms 404 are fixedly connected to the outer wall of the rotating frame 403.

[0042] The stabilizing mechanism 404 includes an arc-shaped plate 4041 fixedly mounted on the rotating frame 403. Several inner support rods 4042 are equidistantly arranged on the inner wall of the arc-shaped plate 4041, and the outer ends of the inner support rods 4042 are wrapped with a rubber layer.

[0043] In this embodiment, the stabilizing component 4, driven by the rotary motor 401, rotates the rotating frame 403 and its stabilizing mechanism 404, allowing the arc-shaped plate 4041 and the inner support rod 4042 to flexibly limit and support the model from the side. The rubber-coated support rod provides stable clamping while avoiding scratches or indentations on the model surface. In particular, it effectively suppresses model shaking when the mechanical claw 203 performs the pulling operation, ensuring the smoothness and reliability of the support material removal process, further protecting the integrity of the model and improving the removal success rate.
