[0023] This application provides a detachable platform for a DLP printer, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0025] Please see Figure 1-4This embodiment provides a detachable platform for a DLP printer, comprising: a base plate 1, with two first electric guide rails 2 mounted on the top of the base plate 1, a movable plate 201 mounted on the top of the first electric guide rails 2, and a placement plate 4 on the top of the movable plate 201; a quick-release assembly disposed between the placement plate 4 and the movable plate 201, the quick-release assembly comprising: a mounting block 202, a mounting groove 203, a slot 402, a fixing groove 5, and a fixing block 501; and a cleaning assembly disposed between the base plate 1 and the placement plate 4, the cleaning assembly comprising: a device block 6, a device groove 601, a threaded rod 602, a drive motor 603, and a drive rod 604; two symmetrically arranged second electric guide rails 3 mounted on the top of the base plate 1, lifting sliders 301 disposed on the outer side of the second electric guide rails 3, a third electric guide rail 302 mounted between the two lifting sliders 301, a sliding block 303 disposed on the third electric guide rail 302, and a print head 304 mounted on the bottom of the sliding block 303.

[0026] The position of the placement plate 4 in the Z-axis direction can be changed by setting the first electric guide rail 2, the position of the print head 304 in the Y-axis direction can be changed by setting the second electric guide rail 3, and the position of the print head 304 in the Z-axis direction can be changed by setting the third electric guide rail 302.

[0027] The quick-release components and placement plate allow for rapid disassembly and assembly of the placement plate 4, enabling users to easily remove the entire platform from the printer and then handle the removal of printed parts in a more convenient location. The cleaning component allows for cleaning of the surface of the placement plate 4 after printing, saving time on cleaning the surface of the placement plate 4. Example

[0028] Based on Embodiment 1, a mounting block 202 is installed on the top of the movable plate 201. A mounting groove 203 is formed on the top of the mounting block 202. A placement block 401, matching the mounting groove 203, is connected to the bottom of the placement plate 4. Two slots 402 are formed on each opposite side of the placement block 401. Multiple ejection slots 204 communicating with the mounting groove 203 are formed inside the mounting block 202. Ejection springs 205 are connected inside the ejection slots 204. An ejection block 206 is connected to the top of the ejection spring 205, and the top of the ejection block 206 is connected to the placement block 401. 1. The ground is in contact with each other. The mounting block 202 has two fixing grooves 5 on both sides. The fixing block 501 passes through the fixing groove 5 and one end of the fixing block 501 extends into the slot 402 and has an inclined surface. One end of the two fixing blocks 501 on the same side is connected to the same fixing plate 502. The mounting block 202 has a limiting groove that communicates with the fixing groove 5. The limiting groove is slidably connected to the limiting plate 503 and the fixing block 501. The limiting plate 503 is connected to the limiting groove and the limiting spring 504 is connected between the limiting plate 503 and the limiting groove.

[0029] After the workpiece is printed on the placement plate 4, especially for objects with complex shapes, it is difficult to remove the finished product from the placement plate 4. In this case, it is necessary to remove the placement plate 4 together with the workpiece and then handle the removal of the printed part in a more convenient position. At this time, the fixing plates 502 on both sides can be pulled, so that the fixing plates 502 drive the fixing blocks 501 to move backward, so that the fixing blocks 501 separate from the slots 402. During the process of the placement plate 4 being installed into the mounting block 202, the placement block 401 enters the mounting groove 203 and squeezes the ejector block 20. 6. The ejector spring 205 is compressed and accumulates elastic force. At this time, the ejector spring 205 releases the elastic force and lifts the placement block 401 through the ejector block 206, so that the slot 402 is misaligned with the fixed block 501, and the fixed plate 502 can be released. Then the placement plate 4 is removed from the mounting block 202, and the printing platform is disassembled. The detachable placement plate 4 setting allows for quick replacement of the used platform so that a new printing task can be started immediately without waiting for the current print to be completely cleaned up before continuing.

[0030] Then, the new placement plate 4 is placed above the mounting block 202, and the placement block 401 is placed into the mounting groove 203, so that the placement block 401 is re-pressed by the ejector block 206 against the ejector spring 205. During the placement process, the placement block 401 contacts the inclined surface of the fixing block 501 and squeezes the fixing block 501 into the fixing groove 5. The limiting spring 504 is compressed and accumulates elastic force. After the fixing block 501 is aligned with the slot 402, the limiting spring 504 releases its elastic force, so that the fixing block 501 springs into the slot 402. Through the setting of the limiting groove and the limiting plate 503, the movement direction and distance of the fixing block 501 can be limited. Example

[0031] Based on Embodiment 1, two symmetrically arranged equipment blocks 6 are installed on the top of the base plate 1. Equipment slots 601 are opened on the top of the equipment blocks 6. Threaded rods 602 are rotatably connected inside the equipment slots 601. A drive motor 603 is installed on the surface of the equipment blocks 6, and the drive shaft of the drive motor 603 is connected to the threaded rods 602. A drive rod 604 with an inverted U-shaped structure is provided on the top of the base plate 1, and both ends of the drive rod 604 are threadedly connected to the threaded rods 602. A brush is provided at the bottom of the drive rod 604.

[0032] After the printed parts are removed, some residual waste material will inevitably remain on the placement plate 4. At this time, the drive motor 603 drives the threaded rod 602 to rotate, so that the threaded rod 602 drives the drive rod 604 to move under the action of thread engagement. This causes the brush on the drive rod 604 to sweep across the surface of the placement plate 4, cleaning up the residual waste material, improving the efficiency of printing preparation, and avoiding the residual material from affecting the quality of the next print.

[0033] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
