Description

Technical Field

[0001] The utility model belongs to the technical field of industrial-grade printers, and specifically relates to a light-curing SLA industrial-grade 3D printer. Background Art

[0002] The light-curing industrial 3D printer is an advanced additive manufacturing device that uses light-curing molding technology to irradiate liquid photosensitive resin layer by layer through a light source of a specific wavelength, so that the resin is cured to form a three-dimensional object;

[0003] However, during use, since the light source is directional, the side of the photosensitive resin that is not irradiated may remain in liquid form and be soft, which may cause the printed three-dimensional object to fall over. When the three-dimensional object falls over and the resin solidifies, the operator needs to clean the printed objects on the printer base plate. The current common treatment method is to disassemble the base plate and remove the damaged prints manually or with the help of tools. This cleaning method is relatively cumbersome and requires a lot of time and manpower. Especially when printing errors need to be handled frequently, the cleaning of the base plate seriously affects the efficiency of the entire printing process. The long cleaning process leads to the idleness of the equipment, reduces the printing output per unit time, increases production costs, and greatly limits the application of light-curing industrial-grade 3D printers in efficient production.

[0004] In order to solve the above problems, a light-curing SLA industrial-grade 3D printer is proposed in this application. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 A light-curing SLA industrial-grade 3D printer comprises a workbench 1, a stand 2 is fixedly connected to the top of the workbench 1, two stands 2 are provided, the two stands 2 are respectively located on both sides of the bottom of the workbench 1, the outer side walls of the two stands 2 are respectively fixedly connected to electric telescopic rods 3, the two electric telescopic rods 3 are respectively connected to an external power supply, the inner side walls of the two stands 2 are slidably connected to a rotating drive rod 4, one end of the rotating drive rod 4 is fixedly connected to a stepping motor, and the outer side walls of the rotating drive rod 4 are respectively rotatably connected to the output ends of the two electric telescopic rods 3, the outer side wall of the rotating drive rod 4 is fixedly connected to a mounting frame 5, the outer side wall of the mounting frame 5 is fixedly connected to a printing base plate 6, two printing base plates 6 are provided, and the two printing base plates 6 are respectively connected to the outer side walls of the two stands 2. The top and bottom of the mounting frame 5 are located respectively. A slide groove 7 is penetrated through the inner bottom wall of the workbench 1. There are two slide grooves 7. The two slide grooves 7 are symmetrically distributed on the central axis plane of the bottom of the workbench 1. A threaded rod 8 is fixedly connected to the inner bottom of the workbench 1. One end of the threaded rod 8 is fixedly connected to a servo motor, and the servo motor is connected to an external power supply. The outer wall of the threaded rod 8 is threadedly connected to a moving seat 9. Two blocks 15 are arranged at the bottom of the moving seat 9. The outer walls of the two blocks 15 are respectively matched with the inner walls of the two slide grooves 7. A plurality of springs are arranged inside the moving seat 9. The plurality of springs are distributed inside the moving seat 9 in a linear array. A scraper 10 is fixedly connected to the top of the moving seat 9. The scraper 10 is fixedly connected to the moving seat 9 through a plurality of springs.

[0023] When in use, when an error occurs in the printing of a workpiece, resulting in damage to the printed workpiece, the operator can start the two electric telescopic rods 3, and the two electric telescopic rods 3 adjust the height of the mounting frame 5, thereby driving the printing base plate 6 to move toward the inside of the workbench 1. When the two printing base plates 6 move to the inside of the workbench 1, the operator can start the stepper motor at one end of the rotating drive rod 4, thereby rotating the rotating drive rod 4. Because the outer wall of the rotating drive rod 4 is fixedly connected to the inner wall of the mounting frame 5, when the stepper motor drives the rotating drive rod 4 to rotate, at the same time It will drive the mounting frame 5 and the printing base plate 6 to rotate synchronously with the rotating drive rod 4, and then rotate the damaged workpiece to the bottom. At this time, the servo motor at one end of the threaded rod 8 is started, and the servo motor drives the threaded rod 8 to rotate, thereby driving the moving seat 9 to move. As the moving seat 9 moves, the scraper 10 located on the top of the moving seat 9 cleans the outer wall of one of the printing base plates 6 with the damaged workpiece to facilitate the next use. At the same time, the two electric telescopic rods 3 are started to push the other unused printing base plate 6 toward the top of the workbench 1 to facilitate continued printing.

[0024] Reference Figure 4 The top of the workbench 1 is fixedly connected to the limit frame 11, the printing base plate 6 is located in the middle position of the limit frame 11, and the outer walls of the printing base plate 6 are respectively fitted with the inner walls of the limit frame 11. The inner wall of the limit frame 11 is provided with a receiving groove 12, and eight receiving grooves 12 are provided. The eight receiving grooves 12 are divided into four groups of two. The four groups of receiving grooves 12 are respectively located around the inner wall of the limit frame 11, and the outer wall of the limit frame 11 is provided with sliding holes 13. The positions and numbers of the sliding holes 13 correspond to the positions and numbers of the eight receiving grooves 12. The limit frame 11 is slidably connected with eight sliding posts 14 through the eight sliding holes 13. The eight sliding posts 14 are close to the inner wall of the limit frame 11. One end is fixedly connected with a card block 15, and the outer side walls of the eight card blocks 15 are provided with an arc, and the arc is located on the side of the eight card blocks 15 close to the bottom of the workbench 1, and the outer side walls of the eight slide columns 14 are wound with a return spring 16. When the printing base plate 6 moves toward the top of the workbench 1 along the direction of the workbench 1, the top of the printing base plate 6 first contacts the outer side wall of the card block 15. As the printing base plate 6 continues to rise, the outer side wall of the printing base plate 6 contacts the card block 15, and then squeezes the card block 15 into the interior of the accommodating groove 12. When the printing base plate 6 is located at the top of the card block 15, under the action of the return spring 16, the card block 15 pops out from the interior of the accommodating groove 12 to support the printing base plate 6.

[0025] Reference Figure 3 and Figure 4One end of the sliding column 14 away from the block 15 is fixedly connected with an adjusting rod 17, and the adjusting rod 17 is located outside the limit frame 11. Four adjusting rods 17 are provided, and the four adjusting rods 17 are respectively parallel to the outer side walls of the limit frame 11, and both ends of the four adjusting rods 17 are provided with oblique grooves 18, and the oblique grooves 18 have an inclined angle, and the oblique groove 18 opened on the side of the adjusting rod 17 close to the outer side wall of the limit frame 11 is deeper.

[0026] Reference Figure 3 and Figure 4 The outer wall of the limit frame 11 is fixedly connected with a threaded column 19, and the outer wall of the threaded column 19 is slidably connected with a sliding sleeve 20. The end of the sliding sleeve 20 away from the limit frame 11 is rotatably connected with a threaded sleeve 22. The inner wall of the threaded sleeve 22 is threadedly connected to the outer wall of the threaded column 19. When the operator needs to adjust the position of the sliding sleeve 20, the threaded sleeve 22 can be rotated, and the threaded sleeve 22 moves along the outer wall of the threaded column 19 to drive the sliding sleeve 20 to move.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The outer wall of the sliding sleeve 20 is fixedly connected with an extrusion block 21, and the outer wall of the extrusion block 21 fits with the inner wall of the inclined groove 18. The end of the extrusion block 21 away from the sliding sleeve 20 is respectively located inside the inclined groove 18. When the operator rotates the threaded sleeve 22, the sliding sleeve 20 will gradually move away from the limit frame 11. At this time, the sliding sleeve 20 drives the extrusion block 21 to move away from the limit frame 11. Because the extrusion blocks 21 are all located inside the inclined groove 18, and the inclined groove 18 is set at an inclined angle, the inclined groove 18 is close to the limit frame 11. One end near the limit frame 11 is deeper, so when the extrusion block 21 follows the sliding sleeve 20 and gradually moves away from the limit frame 11, the two ends of the extrusion block 21 will slide along the inside of the inclined groove 18, and then open the two adjustment rods 17, thereby driving the adjustment rods 17 to pull the sliding column 14 and the card block 15 toward the inside of the accommodating groove 12 to shrink, so as to facilitate the adjustment of the horizontal height of the printing base plate 6. The top of the limit frame 11 is fixedly connected with a printing device 23, and the printing device 23 is located above the printing base plate 6.

[0028] Working principle: When in use, the operator starts the printing device 23, and the printing device 23 prints the workpiece on the top of the printing base plate 6. When an error occurs in the printing of the workpiece, resulting in damage to the printed workpiece, the operator can start the two electric telescopic rods 3, and the two electric telescopic rods 3 adjust the height of the mounting frame 5, thereby driving the printing base plate 6 to move toward the inside of the workbench 1. When the two printing base plates 6 move to the inside of the workbench 1, the operator can start the stepper motor at one end of the rotating drive rod 4, thereby rotating the rotating drive rod 4. Because the outer wall of the rotating drive rod 4 is fixedly connected to the inner wall of the mounting frame 5, Therefore, when the stepper motor drives the rotary drive rod 4 to rotate, it will also drive the mounting frame 5 and the printing base plate 6 to rotate synchronously with the rotary drive rod 4, thereby rotating the damaged workpiece to the bottom. At this time, the servo motor at one end of the threaded rod 8 is started, and the servo motor drives the threaded rod 8 to rotate, thereby driving the moving seat 9 to move. As the moving seat 9 moves, the scraper 10 located on the top of the moving seat 9 cleans the outer wall of one of the printing base plates 6 with the damaged workpiece, so as to facilitate the next use. At the same time, the two electric telescopic rods 3 are started to push the other unused printing base plate 6 toward the top of the workbench 1, so as to facilitate continued printing.

[0029] When the printing base plate 6 needs to be replaced, the operator can rotate the threaded sleeve 22, and the threaded sleeve 22 drives the sliding sleeve 20 to move along the threaded column 19. When the extrusion block 21 follows the sliding sleeve 20 and gradually moves away from the limit frame 11, the two ends of the extrusion block 21 will slide along the inside of the inclined groove 18, and then open the two adjustment rods 17, thereby driving the adjustment rod 17 to pull the sliding column 14 and the card block 15 to retract toward the inside of the accommodating groove 12, so as to facilitate the adjustment of the horizontal height of the printing base plate 6.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
