Description

Technical Field

[0001] The present invention relates to the technical field of resin 3D printing equipment, and in particular to an automatic resin 3D printer. Background Art

[0002] LCD resin 3D printers and DLP resin 3D printers usually use ultraviolet light to project or irradiate from under the material tank onto a printing platform immersed in photosensitive resin liquid at the bottom of the material tank, so that the photosensitive resin between the printing platform and the bottom of the material tank is solidified on the printing platform at the ultraviolet light projection or irradiation area. The printing platform moves upward layer by layer and is exposed layer by layer to generate a three-dimensional printed part.

[0003] However, after the 3D print is completed, manual intervention is required to scrape the 3D print from the printing platform to separate the 3D print from the printing platform. The printing platform must also be manually wiped clean before the next batch of printing can be started. Although the patent CN114734639A introduces a shoveling mechanism, a 3D printer, and a 3D printing method with functions such as automatic shoveling, automatic collection of printed parts, and automatic liquid addition, the receiving tray is located in the front, making it very inconvenient to clean and maintain the material trough through the receiving tray. In addition, the receiving assembly, shoveling assembly, and pushing assembly all have their own movable guide rails and drive systems. The control program is cumbersome and the system is complex, affecting the stable and reliable operation of the equipment.

[0004] Therefore, an automatic resin 3D printer that can automatically peel off the printed parts on the printing platform and has a simple control program is in urgent need of research. Summary of the Invention

[0052] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0053] The following describes an automatic resin 3D printer according to some embodiments of the present invention with reference to the accompanying drawings.

[0054] See also Figures 1 to 6, an automatic resin 3D printer provided by an embodiment of the present invention includes a machine base 1, a printing platform 2, a shovel system and a driving mechanism 6, the machine base 1 is provided with a material trough 101 and a drop port 102; the printing platform 2 is arranged above the material trough 101 and is vertically movably connected to the machine base 1; the shovel system includes a receiving mechanism 3 and a shovel mechanism 4, the receiving mechanism 3 is connected to the shovel mechanism 4; the shovel system is movably arranged on the machine base 1; the driving mechanism 6 is connected to the mechanism system; the driving mechanism 6 is used to drive the shovel mechanism to move back and forth between the corresponding position below the printing platform 2 and the corresponding position above the drop port 102; wherein the receiving mechanism 3 includes a receiving groove 301 and a drop gate 304 for switching the bottom of the receiving groove 301 to be opened or closed, and the receiving groove 301 is connected to the shovel machine On the mechanism 4, the side of the drop gate 304 is connected to the first slider 605, and the first slider 605 is connected to the guide rod 302. The shovel mechanism 4 can be movably connected to the guide rod 302 along the length direction of the guide rod 302, and the guide rod 302 is provided with a first spring 303; a stopper 8 is provided on the machine base 1, and the stopper 8 is used to contact the first slider 605 when the shovel system moves to the corresponding position above the drop port 102 to limit the movement of the first slider 605; when the first slider 605 does not contact the stopper 8, the first spring 303 is used to keep the drop gate 304 in a closed state at the bottom of the receiving groove 301; when the first slider 605 contacts the stopper 8, the first spring 303 is compressed by the shovel mechanism 4, so that the drop gate 304 switches the bottom of the receiving groove 301 to an open state.

[0055] Here, the first spring 303 is sleeved on the guide rod 202 and is located between the first slider 605 and the shovel mechanism 4 ; the guide rod 302 is arranged along the moving direction of the connecting mechanism 3 .

[0056] It should be noted that an LCD screen, a projector or a light source are installed in the machine base 1; the printing platform 2 is installed on the machine base 1 through the Z-axis lifting system 5; and the connecting slot 301 is not provided with a bottom plate.

[0057] When the first sliding block 605 contacts the stopper 8 , the receiving groove 301 is located directly above the dropping opening 102 .

[0058] Before the automatic resin 3D printer provided in this embodiment starts printing, the Z-axis lifting system 5 drives the printing platform 2 mounted thereon to move to the bottom of the material trough 101 to start printing the printed part; after the printing of the printed part is completed, the Z-axis lifting system 5 drives the printing platform 2 to move upward to a preset position, and then the driving mechanism 6 drives the shovel mechanism 4 to move, and the receiving mechanism 3 moves with the shovel mechanism 4 to the corresponding position below the printing platform 2, so that the blade of the shovel mechanism 4 is in close contact with the lower surface of the printing platform 2, and the shovel mechanism 4 is pressed against the bottom surface of the printing platform 2. It moves relative to the lower surface of the printing platform 2 so that the printed part located on the printing platform 2 is shoveled off by the shoveling mechanism 4 and falls into the receiving slot 301 on the receiving mechanism 3; then, the driving mechanism 6 continues to drive the shoveling mechanism 4 to move, so that the first slider 605 contacts the stopper 8 as the shoveling mechanism 4 moves, so that the first spring 303 is compressed by the shoveling mechanism 4, and then the drop gate 304 switches the bottom of the receiving slot 301 to an open state, that is, the bottom of the receiving slot 301 is opened, so that the printed part located in the receiving slot 301 enters the drop port 102 on the machine base 1.

[0059] In this embodiment, a receiving mechanism 3 is provided on the shoveling system so that the receiving mechanism 3 moves with the shoveling system to a corresponding position below the printing platform 2 and moves from one side of the printing platform 2 to the opposite side, closely adhering to the lower surface of the printing platform 2. After the shoveling mechanism 4 shovels the printed part on the printing platform 2, the printed part can directly fall into the receiving mechanism 3, thereby realizing automatic continuous production of the automatic resin 3D printer and improving printing efficiency. At the same time, after the receiving mechanism 3 moves to a corresponding position above the drop port 102 under the control of the driving mechanism 6, the first slider 605 connected to the drop port gate 304 contacts the stopper 8 and is compressed by the shoveling mechanism 4 using the first spring 303, causing the drop port gate 304 to switch the bottom of the receiving slot 301 to an open state, thereby opening the bottom of the receiving slot 301 and realizing that the printed part in the receiving slot 301 automatically enters the drop port 102 on the machine base 1, thereby realizing automation of the processes of the automatic resin 3D printer, including printing, shoveling, receiving, and feeding. In summary, the automatic resin 3D printer provided by this application can reduce the pollution of printing materials to people or equipment, and can also achieve high printing efficiency of the automatic resin 3D printer under unattended operation.

[0060] In some possible embodiments, the drop gate 304 includes a gate plate 3041 and a gate opening 3042 opened on the gate plate 3041. Figure 4 When the first slider 605 is not in contact with the stopper 8, the gate plate 3041 is located at the bottom of the connecting groove 301; Figure 5When the first slider 605 contacts the stopper 8 and the first spring 303 is compressed to the set position by the shovel mechanism 4 , the gate 3042 is located at the bottom of the receiving groove 301 .

[0061] It should be noted that the closed state of the drop gate 304 can be understood as the state in which the part of the gate plate 3041 without the gate door 3042 is located at the bottom of the receiving slot 301; the open state of the drop gate 304 can be understood as the state in which the gate door 3042 is located at the bottom of the receiving slot 301.

[0062] Among them, see Figure 2 When the receiving mechanism 3 moves with the shoveling system to the corresponding position below the printing platform 2, the portion of the gate plate 3041 without the gate door 3042 is used to receive the printed parts shoveled off by the shoveling mechanism 4; see Figure 3 When the receiving mechanism 3 moves with the shovel system to the corresponding position above the drop port 102, the gate door 3042 is located directly above the drop port 102, and the portion of the gate plate 3041 without the gate door 3042 is located between the drop port 102 and the material trough 101; one end of the guide rod 302 is fixedly mounted on the end of the drop port gate 304 close to the stop block 8, and when the drop port gate 304 is located directly above the material trough 101, the receiving slot 301 is located above the portion of the gate plate 3041 without the gate door 3042; when the gate door 3042 is located directly above the drop port 102, when the first spring 303 is compressed to the set position by the shovel mechanism 4, the receiving slot 301 can move toward the gate door 3042 to allow the printed piece located on the receiving slot 301 to enter the drop port 102 after passing through the gate door 3042.

[0063] In this embodiment, when the receiving mechanism 3 moves with the shovel system to the corresponding position above the drop port 102, by making the gate door 3042 located directly above the drop port 102, and making the part of the gate plate 3041 without the gate door 3042 located between the drop port 102 and the material trough 101, the printed part located on the receiving trough 301 can be moved toward the gate door 3042 in the receiving trough 301, and the printed part located on the receiving trough 301 can enter the drop port 102 after passing through the gate door 3042, thereby completing the collection of the printed part by the collection device located below the drop port 102.

[0064] Furthermore, the shovel mechanism 4 includes a fixed frame 401, a swing frame 402, a scraper 403 and a second spring 404. The fixed frame 401 is movably connected to the guide rod 302, and the connecting groove 301 is installed on the fixed frame 401; the swing frame 402 is rotatably installed on the fixed frame 401 through the swing shaft 405; the top surface of the swing frame 402 is tilted, and when the shovel system is located at a corresponding position above the drop port 102, the distance between the end of the top surface of the swing frame 402 away from the printing platform 2 and the printing platform 2 is greater than the distance between the end of the top surface of the swing frame 402 close to the printing platform 2 and the printing platform 2; the scraper 403 is installed on the top surface of the swing frame 402; the length direction of the scraper 403 is the same as the width direction of the machine base 1; one end of the second spring 404 is connected to the fixed frame 401, and the other end is connected to the bottom surface of the swing frame 402.

[0065] By installing the connecting slot 301 on the fixing frame 401, the connecting slot 301 can move along the length direction of the guide rod 302 with the fixing frame 401, thereby achieving the goal of pushing the printed part located on the part of the gate plate 3041 without the gate door 3042 into the drop gate 304 by the connecting slot 301.

[0066] In this embodiment, by tilting the top surface of the swing frame 402, when the shovel system is located at the corresponding position above the drop port 102, the distance between the end of the top surface of the swing frame 402 away from the printing platform 2 and the printing platform 2 is greater than the distance between the end of the top surface of the swing frame 402 close to the printing platform 2 and the printing platform 2, so that the scraper 403 installed on the top surface of the swing frame 402 has the same tilt setting as the top surface of the swing frame 402. At the same time, the swing frame 402 is rotatably mounted on the fixed frame 401 through the swing shaft 405, and one end of the second spring 404 is connected to the fixed frame 401, and the other end of the second spring 404 is connected to the bottom surface of the swing frame 402, so that when the shovel mechanism 4 moves toward the printing platform 2, the swing frame 402 can swing on the fixed frame 401 and the rebound effect of the second spring 404, so that the scraper 403 can contact and fit with the printing platform 2, so that the printed part located on the printing platform 2 can be smoothly scraped off by the scraper 403.

[0067] Furthermore, the connecting slot 301 includes a first side plate 3011 and two oppositely arranged second side plates 3012 . Both sides of the first side plate 3011 are respectively connected to a second side plate 3012 ; the second side plates 3012 are connected to the connecting frame 401 .

[0068] Here, when the receiving mechanism 3 moves with the shoveling mechanism 4 to the corresponding position above the drop-off port 102, the first side panel 3011 is connected to the side of the second side panel 3012 close to the printing platform 2, so that the printed part located on the part of the gate plate 3041 where the gate door 3042 is not opened can be pushed into the drop-off gate 304 by the first side panel 3011.

[0069] Optionally, the driving mechanism 6 includes a second slider 606, a belt 601, a transmission assembly and a motor 602, the second slider 606 is connected to the fixed frame 401; the belt 601 is arranged along the length direction of the machine base 1 and is connected to the second slider 606; the transmission assembly includes a driving pulley 603 and a driven pulley 604, the belt 601 is sleeved on the driving pulley 603 and the driven pulley 604; the motor 602 is driven and connected to the driving pulley 603, for driving the driving pulley 603 to rotate, so that the belt 601 drives the fixed frame 401 connected to the second slider 606 to move along the length direction of the machine base 1.

[0070] Here, the driving pulley 603 is provided on the main transmission shaft, and the driven pulley 604 is provided on the slave transmission shaft; the motor 602 drives the main transmission shaft to rotate, thereby driving the driving pulley 603 to rotate.

[0071] In this embodiment, by selecting the driving mechanism 6 as a structure consisting of a second slider 606, a belt 601, a transmission assembly and a motor 602, the shovel mechanism 4 connected to the second slider 606 can be driven by the motor 602 and moved back and forth along the length direction of the machine base 1 driven by the belt 601, thereby realizing the reciprocating movement of the shovel system between the corresponding position below the printing platform 2 and the corresponding position above the drop port 102.

[0072] Furthermore, a guide rail assembly 7 is provided on the machine base 1 . The guide rail assembly 7 is located below the belt 601 and is arranged parallel to the belt 601 . The first slider 605 and the second slider 606 are both slidably connected to the guide rail assembly 7 .

[0073] Here, the guide rail assembly 7 is arranged parallel to the belt 601, so that when the belt 601 is driven by the motor 602 and the main transmission assembly, the guide rail assembly 7 can limit the movement of the first slider 605 and the second slider 606 to ensure that the first slider 605 and the second slider 606 keep moving along the length direction of the belt 601.

[0074] Among them, the guide rail assembly 7 includes a guide rail mounting seat and a guide rail, and the guide rail mounting seat is located below the belt 601; the guide rail is arranged on the guide rail mounting seat and is arranged along the length direction of the machine base 1, and the first slider 605 and the second slider 606 are both arranged on the guide rail assembly 7 and can slide along the length direction of the guide rail assembly 7.

[0075] In this embodiment, by providing a guide rail assembly 7 parallel to the belt 601 on the machine base 1, and providing the first slider 605 and the second slider 606 on the guide rail assembly 7 so that they can slide along the length direction of the guide rail assembly 7, the first slider 605 and the second slider 606 can be moved along the length direction of the belt 601 when moving with the belt 601, thereby causing the drop gate 304 connected to the first slider 605 and the fixing frame 401 connected to the second slider 606 to move along the length direction of the belt 601.

[0076] Optionally, the second slider 606 is fixedly connected to the belt 601 ; a stopper 8 is provided on the guide rail assembly 7 , and the stopper 8 is arranged on one side of the trough 101 and close to the blanking port 102 .

[0077] Since the second slider 606 is fixedly connected to the belt 601, when the belt 601 is driven to rotate by the transmission assembly, the fixed frame 401 connected to the second slider 606 also moves accordingly, and then the first slider 605 fixedly connected to the guide rod 302 moves under the cooperation of the first spring 303 and the second slider 606. After the first slider 605 moves to contact the stop block 8, the first slider 605 stops moving, and the second slider 606 continues to move toward the stop block 8, so that the fixed frame 401 connected to the second slider 606 drives the connecting slot 301 to move toward the drop gate 304, so that the print located on the part of the gate plate 3041 where the gate door 3042 is not opened is pushed into the drop gate 304 by the connecting slot 301.

[0078] Furthermore, a connecting block 607 is provided on the first slider 605 . A through hole is provided on the connecting block 607 , and the belt 601 passes through the through hole on the connecting block 607 , so that the connecting block 607 and the belt 601 are movably connected.

[0079] Here, by passing the belt 601 through the through hole on the connecting block 607 so that the connecting block 607 is movably connected to the belt 601, a movable connection between the first slider 605 and the belt 601 can be achieved, that is, after the first slider 605 moves to contact the stop block 8, the belt 601 movably connected to the connecting block 607 is not affected by the stopping movement of the first slider 605 and continues to run, so that the second slider 606 connected to the belt 601 continues to move.

[0080] In some possible embodiments, the automatic resin 3D printer also includes a storage mechanism 9, which includes a storage barrel 901 and a movable connection assembly. The storage barrel 901 is movably installed in the machine base 1, and has a storage position and a discharge position; the storage position is the position where the storage barrel 901 is located below the drop port 102; the discharge position is the position where the storage barrel 901 moves to the outside of the machine base 1; the movable connection assembly is used to movably install the storage barrel 901 on the machine base 1, and enable the storage barrel 901 to move back and forth between the storage position and the discharge position.

[0081] Here, the drop port 102 may be located on one side of the trough 101 .

[0082] In this embodiment, the storage barrel 901 is movably arranged in the machine base 1 through a movable connecting component. After the drop-off gate 304 on the receiving mechanism 3 is moved to the upper position corresponding to the drop-off port 102, the printed parts located on the part of the gate plate 3041 where the gate door 3042 is not opened can be pushed into the storage barrel 901 located below the drop-off port 102 through the receiving groove 301, thereby realizing the collection of the printed parts; and then the mobile connecting component is used to move the storage barrel 901 to the output position located outside the machine base 1, so that the staff can take out the printed parts.

[0083] In some possible embodiments, the automatic resin 3D printer further includes a feeding system 10 , which is used to inject printing material into the material tank 101 .

[0084] In this embodiment, by providing a feeding system 10 on the automatic resin 3D printer, it is possible to facilitate the addition of printing materials into the material tank 101, thereby improving the printing efficiency of the automatic resin 3D printer.
