Description

Technical Field

[0001] The present invention belongs to the field of 3D printing technology, and more specifically, relates to a color 3D printing device and a printing method. Background Art

[0002] The basic principle of DLP 3D printing technology is that digital light sources are projected layer by layer on the surface of liquid photosensitive resin in the form of surface light, and then solidified and formed layer by layer. Compared with other 3D printing technologies, its advantages are that it has the characteristics of high precision, smooth surface, fast production speed, and a wide range of usable materials. The sinking DLP device contains a liquid tank that can hold resin, which is used to hold resin that can be cured after being irradiated with ultraviolet light of a specific wavelength. The DLP imaging system is fixedly placed above the liquid tank, and its imaging surface is just above the liquid tank. Through energy and graphic control, a thin layer of resin of a certain thickness and shape can be solidified each time. A sinking mechanism is set above the liquid tank. After each cross-section exposure is completed, it descends a certain height, so that the currently cured solid resin is bonded to the sinking plate or the last formed resin layer.

[0003] The current color 3D printing devices still have the following problems:

[0004] 1. Generally, there is a lack of sound insulation structure, which results in a large noise when the 3D printing equipment is working, and it is impossible to properly reduce the noise generated by the 3D printing equipment during operation;

[0005] 2. To improve the stability of the 3D printing equipment after installation, the 3D printing equipment is usually installed on top of the base. Since the 3D printing equipment and the base are usually connected by bolts, it is more troublesome to install and disassemble the 3D printing equipment;

[0006] 3. It does not have an automatic cleaning function, which means that the printed products need to be transported to a cleaning site for cleaning, which increases the transportation time and reduces the production efficiency of the product. Summary of the Invention

[0020] 2) After curing a layer, the sinking DLP rises above the liquid surface, and then the inkjet printer solidifies the ink, and then returns to the liquid surface to continue 3D printing, waiting for the products in the two 3D printer bodies to be printed;

[0021] 3) Start the double-headed motor so that the two drive screws drive the two dovetail movable seats to move inward at the same time. When the two 3D printer bodies are separated from the two sound insulation covers and two sound insulation cottons, turn off the double-headed motor;

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When the 3D printer body is removed, the two rectangular force-bearing plates move upward under the action of four coil springs B, and the four circular guide rods move outward under the action of four coil springs A, thereby automatically separating the two movable positioning plates from the 3D printer body, making it easier for staff to remove the 3D printer body.

[0026] In addition, when the 3D printer body is installed, the two rectangular force plates move downward under the action of the 3D printer body's own gravity, and the four circular guide rods move inward under the action of the squeezing protrusions B on all sides, realizing automatic contact between the two movable positioning plates and the 3D printer body, and achieving an automatic positioning effect on the 3D printer body, making it convenient for staff to install the 3D printer body.

[0027] 2. In the present invention, when the two driving screws drive the two dovetail movable seats to move outward at the same time, the two 3D printer bodies move into the two sound insulation covers and two sound insulation cottons, thereby reducing the noise generated by the two 3D printer bodies during operation; when the two driving screws drive the two dovetail movable seats to move inward at the same time, the two 3D printer bodies are separated from the two sound insulation covers and two sound insulation cottons, thereby facilitating the staff to take out the printed products.

[0028] 3. In the present invention, when the two driving screws drive the two dovetail movable seats to move outward simultaneously, the two rows of extrusion protrusions A can push the two circular movable rods on the rear side to move, causing the product cleaning frame to move forward; when the two circular movable rods on the rear side separate from the two rows of extrusion protrusions A, the product cleaning frame returns to its original position under the action of the four coil springs C, causing the product cleaning frame to move back and forth under the action of the two rows of extrusion protrusions A and the four coil springs C, thereby achieving multiple shaking cleaning of printed products;

[0029] In addition, the setting of the three rectangular support bars supports the printed product, so that there is a certain gap between the bottom of the printed product and the inner bottom side of the product cleaning frame, which facilitates the contact between the cleaning liquid in the cleaning shell and the bottom of the printed product; when the product cleaning frame moves forward under the action of the two rows of extrusion protrusions A, the six extrusion protrusions C can push the six circular connecting rods upward, so that the two rectangular push bars push the printed product upward. At this time, the cleaning liquid can contact other positions on the bottom of the product; when the product cleaning frame resets backward under the action of the four coil springs C, the two rectangular push bars automatically move downward under the action of their own gravity, ensuring that the three rectangular support bars are intermittently separated from the printed product, facilitating all-round cleaning of the printed product and improving the cleaning accuracy of the printed product.

When the two 3D printer bodies 400 are separated from the two sound insulation covers 102 and the two sound insulation cottons 103, turn off the double-headed motor 201 to facilitate the staff to take out the printed products; take out the products from the two 3D printer bodies 400, and then place the printed products in the product cleaning frame 503. When the two driving screws 202 drive the two dovetail movable seats 301 to move outward at the same time, the two rows of extrusion protrusions A3011 can push the two circular movable rods 502 on the rear side to move, so that the product cleaning frame 503 moves forward; when the two circular movable rods 502 on the rear side are separated from the two rows of extrusion protrusions A3011, the product cleaning The frame 503 is reset backwards under the action of four coil springs C504, so that the product cleaning frame 503 moves back and forth under the action of two rows of extrusion protrusions A3011 and four coil springs C504, realizing multiple shaking cleaning of the printed product; the arrangement of three rectangular support bars 505 supports the printed product, so that there is a certain gap between the bottom of the printed product and the inner bottom side of the product cleaning frame 503, which facilitates the contact between the cleaning liquid in the cleaning shell 501 and the bottom of the printed product; when the product cleaning frame 503 moves forward under the action of the two rows of extrusion protrusions A3011, the six extrusion protrusions C5061 can push the six circular connecting bars 5061 to move forward. The connecting rod 508 moves upward, causing the two rectangular push bars 507 to push the printed product upward. At this time, the cleaning liquid can contact other positions on the bottom of the product. When the product cleaning frame 503 is reset backward under the action of the four coil springs C504, the two rectangular push bars 507 automatically move downward under their own gravity, ensuring that the three rectangular support bars 505 are intermittently separated from the printed product, facilitating all-round cleaning of the printed product and improving the cleaning accuracy of the printed product. When the two 3D printer bodies 400 move again to the interior of the two sound insulation covers 102 and the two sound insulation cotton pads 103, the product in the product cleaning frame 503 is removed.

[0068] When the 3D printer body 400 is removed, the two rectangular force plates 305 move upward under the action of the four coil springs B309, and the four circular guide rods 303 move outward under the action of the four coil springs A308, thereby realizing the automatic separation of the two movable positioning plates 304 from the 3D printer body 400, making it convenient for the staff to remove the 3D printer body 400; when the 3D printer body 400 is installed, the two rectangular force plates 305 move downward under the action of the 3D printer body 400's own gravity, and the four circular guide rods 303 move inward under the action of the four squeezing protrusions B3061, thereby realizing the automatic contact between the two movable positioning plates 304 and the 3D printer body 400, achieving an automatic positioning effect on the 3D printer body 400, and facilitating the staff to install the 3D printer body 400.
