Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to a photocurable resin 3D printer. Background Art

[0002] 3D photocurable resin 3D printer is a type of 3D printer, but its printing method is different from that of traditional 3D printers. It is mainly composed of laser module, lifting module, molding platform and material tank. When printing, the molding platform is immersed in the photosensitive resin in the material tank under the guidance of the lifting module, and then the laser module will scan the photosensitive resin, and the photosensitive resin scanned by the photosensitive resin will solidify. This process is repeated so that the photosensitive resin forms a specific shape and adheres to the molding platform.

[0003] After the current photocurable resin 3D printer completes printing, the molding platform is generally removed and then the printed body is scraped off the molding platform with a scraper. However, manual operation is very unstable and it is easy to damage the printed body due to mistakes when separating the printed body. Utility Model Content

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Please combine Figures 1 to 4 The photocurable resin 3D printer of this embodiment includes: a printer body 1, on which a molding platform 2, a resin tray 3 and a cover shell 4 are installed. The cover shell 4 is covered on the printer body 1 and can be removed normally so that the resin tray 3 and the molding platform 2 can be removed for cleaning. The cover shell 4 is made of plastic material, and transparent display windows are provided on both sides thereof, so that the operator can see the situation inside the cover shell 4 more intuitively. A driving mechanism is provided on one side of the cover shell 4, and two rotating rods 8 are rotatably installed in the cover shell 4. The driving mechanism and the two rotating rods 8 Transmission connection, a receiving plate 10 is provided on each of the two rotating rods 8, a double-axis motor 11 is fixedly installed on one side of the cover shell 4, two screws 14 are rotatably installed in the cover shell 4, the double-axis motor 11 is transmission connected with the two screws 14, both screws 14 are threaded with internal thread blocks 16, the same connecting strip 17 is fixedly installed on the two internal thread blocks 16, a blade 18 is fixedly installed on the connecting strip 17, the blade 18 is fixed to the connecting strip 17 by screws, it can be disassembled and replaced as needed, and the blade 18 is flush with the bottom of the forming platform 2.

[0022] The driving mechanism includes an electric push rod 5 fixedly mounted on one side of the cover 4, a frame 6 fixedly mounted on the output shaft of the electric push rod 5, racks 7 fixedly mounted on both sides of the frame 6, circular gears 9 fixedly mounted on one end of two rotating rods 8, and the two circular gears 9 are respectively meshed with the corresponding racks 7.

[0023] Through the above technical solution, the driving mechanism is mainly used to drive the two rotating rods 8 to rotate, so that the two rotating rods 8 can drive the two receiving plates 10 to switch between the upright state and the horizontal state, thereby achieving the receiving of the printed body without affecting the lifting and lowering of the forming platform 2.

[0024] Two fixed frames are fixedly installed on one side of the cover shell 4 , and sliding rods are fixedly installed in the two fixed frames. The two sliding rods both penetrate the frame 6 and are slidably connected to the frame 6 .

[0025] Through the above technical solution, the fixed frame and the sliding rod constitute a stabilizing mechanism of the frame 6, which can ensure the stability of the frame 6 without affecting the normal lifting and lowering of the frame 6.

[0026] Two driving rods 12 are rotatably installed on one side of the cover shell 4, and two supporting blocks are fixedly installed on one side of the cover shell 4. The two driving rods 12 respectively penetrate the corresponding supporting blocks and are rotatably connected to the corresponding supporting blocks. One end of the two driving rods 12 is respectively fixedly connected to the two output shafts of the dual-axis motor 11, and the other ends of the two driving rods 12 are fixedly installed with the first bevel gear 13, and one end of the two screws 14 are fixedly installed with the second bevel gear 15, and the two first bevel gears 13 are respectively meshed with the two second bevel gears 15.

[0027] Through the above technical solution, the driving rod 12 , the first bevel gear 13 and the second bevel gear 15 cooperate with each other, so that the dual-axis motor 11 can smoothly drive the two screws 14 to rotate synchronously, thereby ensuring the stable movement of the blade 18 .

[0028] A take-out opening is provided on one side of the cover shell 4, and a blocking cover 19 is hinged on the take-out opening.

[0030] A protective shell 20 is fixedly mounted on one side of the cover shell 4 , and the dual-axis motor 11 and the driving mechanism are both located inside the protective shell 20 .

[0031] Through the above technical solution, the protective shell 20 can shield the dual-axis motor 11 and the driving mechanism inside it, which not only provides protection but also has an aesthetic effect.

[0032] The implementation principle of a photocurable resin 3D printer in the embodiment of the present application is:

[0033] Step 1: When the photocurable resin 3D printer finishes printing, the molding platform 2 drives the printed body to rise from the resin tray 3 until it rises to the top. At this time, the electric push rod 5 is started, and the electric push rod 5 drives the frame 6 and the two racks 7 to descend through the output rod. While the two racks 7 are descending, they drive the two rotating rods 8 to rotate through the two circular gears 9, so that the two rotating rods 8 drive the two receiving plates 10 to rotate 90 degrees to become horizontal plates;

[0034] The second step: start the dual-axis motor 11, the dual-axis motor 11 drives the two driving rods 12 and the two first bevel gears 13 to rotate through the output shaft, the two first bevel gears 13 drive the two screws 14 to rotate through the two second bevel gears 15, under the action of the thread, the two screws 14 drive the two internal thread blocks 16, the connecting strip 17 and the blade 18 to move, the blade 18 starts to shovel the print body from the bottom of the forming platform 2 as it moves, and then the shoveled print body falls onto the two receiving plates 10, at this time, open the baffle 19 to take the print body out of the cover 4, thereby completing the automatic separation of the print body.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
