[0002] 3D printing equipment is a device that builds objects layer by layer based on digital models and is widely used in various fields. Its workflow generally includes three stages: printing, cleaning, and curing. Printing involves building the model layer by layer; cleaning removes residues from the printed surface; and curing enhances the model's strength using methods such as ultraviolet light. However, most current 3D printing equipment separates printing, cleaning, and curing, with each stage operating independently. This results in low automation, requiring multiple manual interventions, cumbersome and inefficient operation, and large equipment footprint, making it difficult to meet the demands of rapid production and efficient operation. Utility Model Content

The cleaning slot is used to hold cleaning fluid. The first drive structure is used to drive the printing platform to move relatively closer to or away from the printing slot. The first drive structure is also used to drive the printing platform to move into the cleaning slot.

[0006] According to some embodiments of the present invention, the curing device includes a curing device body disposed on one side of the printer housing and a power cord, wherein the curing device body and the power cord can be housed inside the printer housing.

[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0025] An embodiment of this utility model provides a 3D printing device, such as... Figure 1-4As shown, the device includes a printer housing 1, a printing slot 2 disposed on the printer housing 1, a cleaning tank 300 disposed on one side of the printing slot 2, a first drive structure 403 disposed on the printer housing 1, a printing platform 402 disposed on the first drive structure 403, and a curing device 500 disposed on one side of the printer housing 1 for curing the printed parts. The cleaning tank 300 is used to hold cleaning fluid. The first drive structure 403 is used to drive the printing platform 402 to move relatively closer to or away from the printing slot 2. The first drive structure 403 can also be used to drive the printing platform 402 to move into the cleaning tank 300.

[0026] This 3D printing equipment integrates printing and cleaning functions into a single device, equipped with a curing unit 500, greatly improving practicality and reducing space requirements. The first drive structure 403 can move the printing platform 402 closer to or further away from the printing tank 2, allowing the material in the printing tank 2 to be cured layer by layer onto the printing platform 402 for printing. After printing, the first drive structure 403 can move the printing platform 402 and the printed parts onto it to a cleaning tank 300 containing cleaning fluid. The cleaning fluid cleans the residue on the printing platform 402 and the printed parts by shaking or rotating the first drive structure 403 or by shaking the cleaning tank 300. The first drive structure 403 achieves automatic post-printing cleaning, allowing the printing platform 402 to automatically switch between the printing tank 2 and the cleaning tank 300 without manual transfer of the printed parts, greatly improving operational convenience and efficiency and reducing human error. After cleaning, the printed parts are moved to the curing unit 500 for curing. The seamless integration of each step shortens the production cycle, making it particularly suitable for mass production. The curing device 500 can be integrated into one side of the printing device or separated and installed on the same side, making it convenient to use together.

[0027] In some embodiments, such as Figure 1-2 As shown, the curing device 500 includes a curing device body 501 disposed on one side of the printer housing 1 and a power cord, and the curing device body 501 and the power cord can be stored inside the printer housing 1.

[0028] To further reduce the size, the curing device 500 is not embedded in the printer housing 1. By setting up a separate curing device body 501 and a power cord connected to the printer housing 1, the curing device body 501 can be stored in the printer housing 1 when the printing function is not in use or when the curing device 500 is not in use, thus reducing the space occupied. This makes the overall appearance of the device simple and compact, saves space, facilitates storage, and greatly reduces transportation costs.

[0029] Furthermore, the bottom of the curing device body 501 has a groove that matches the top of the printing slot 2, so that the curing device body 501 can be locked above the printing slot 2.

[0030] The groove at the bottom allows the curing device 500 to be securely mounted above the printing slot 2, increasing its stability and preventing it from slipping off when bumped or shaken.

[0031] In some embodiments, such as Figure 1-4 As shown, the first drive structure 403 includes a first linear drive mechanism 404 disposed on the printer housing 1 and a second linear drive mechanism 405 connected to the first linear drive mechanism 404. The first linear drive mechanism 404 can reciprocate in the vertical direction, and the second linear drive mechanism 405 can reciprocate in the direction from the printing slot 2 to the cleaning slot 300. The printing platform 402 is disposed on the first linear drive mechanism 404 or the second linear drive mechanism 405.

[0032] The combination of the first linear drive mechanism 404 and the second linear drive mechanism 405 enables precise vertical and horizontal movement of the printing platform 402. The vertical movement of the first linear drive mechanism 404 precisely controls the distance between the printing platform 402 and the printing slot 2, meeting the height adjustment requirements during the printing process. The reciprocating motion of the second linear drive mechanism 405 along the direction from the printing slot 2 to the cleaning slot 300 allows the printing platform 402 to flexibly switch between the printing slot 2 and the cleaning slot 300, achieving seamless integration of printing and cleaning functions. The first linear drive mechanism 404 and the second linear drive mechanism 405 can be transmission structures such as screw drives, belt drives, and rack and pinion drives. In this embodiment, the first linear drive mechanism 404 is a screw drive structure capable of reciprocating vertically, and the second linear drive mechanism 405 is a transmission structure connected to the first linear drive mechanism 404 capable of reciprocating horizontally, resulting in a simple and flexible structure. After printing is completed, the second linear drive mechanism 405 can drive the printing platform 402 to move above the cleaning tank 300. Then, the first linear drive mechanism 404 drives the second linear drive mechanism 405 and the printing platform 402 to move downwards until the printing platform 402 enters the cleaning tank 300, so that the workpiece is immersed in the cleaning liquid. At this time, the first linear drive mechanism 404 can move up and down, while the second linear drive mechanism 405 can drive the printing platform 402 to move laterally, resulting in a good cleaning effect.

[0033] Furthermore, such as Figure 3 As shown, the first linear drive mechanism 404 includes a first slide rail 406 vertically disposed above the printing slot 2 and a first slide block 407 slidably connected to the first slide rail 406. The second linear drive mechanism 405 includes a second slide rail 408 connected to the first slide block 407 and a second slide block 409 slidably connected to the second slide rail 408. The printing platform 402 is disposed on the second slide block 409.

[0034] The first slide rail 406 and the first slide block 407 enable the printing platform 402 to move stably in the vertical direction, ensuring the accuracy of height adjustment during the printing process; the second slide rail 408 and the second slide block 409 enable the printing platform 402 to move flexibly in the horizontal direction. The two work together to enable it to accurately switch to the printing tank 2 or the cleaning tank 300.

[0035] Furthermore, such as Figure 3 As shown, a first limiting structure 410 is provided on one side of the second slide rail 408. The first limiting structure 410 is used to limit the position of the printing platform 402 in the horizontal direction.

[0036] Specifically, during normal printing, the first linear drive mechanism 404 operates to drive the second linear drive mechanism 405 and the printing platform 402 to move up and down. The first limiting structure 410 can limit the horizontal position of the printing platform 402 and the second linear drive mechanism 405 to ensure that the printing platform 402 can move vertically with the first linear drive mechanism 404 during printing, thereby ensuring printing quality. In this embodiment, the first limiting structure 410 is a structure that is fixed by magnetic attraction. Furthermore, it can also be a limiting structure such as a snap-fit.

[0037] In some embodiments, such as Figure 3-4 As shown, the printing platform 402 includes a printing platform body 411 and a rotating device 412 for driving the printing platform body 411 to rotate.

[0038] The printing platform body 411 is driven to rotate by the rotating device 412, which enables the printing platform body 411 to rotate during and after cleaning, making it convenient to pour out the accumulated liquid in the workpiece holes and improving cleaning efficiency and effect.

[0039] Furthermore, such as Figure 4 As shown, the rotating device 412 includes a second driving structure for driving the printing platform body 411 to rotate and a second limiting structure 413 for limiting the rotation angle of the printing platform body 411.

[0040] The second limiting structure 413 has a limiting state and a releasing limiting state. When the printing platform body 411 rotates to the preset position, the second limiting structure 413 can restrict the rotation of the printing platform body 411 and enter the limiting state. When the second driving structure drives the printing platform body 411 to rotate, the second limiting structure 413 releases the limiting state from the printing platform body 411.

[0041] Since the rotating device 412 can drive the printing platform body 411 to rotate via the drive motor, the second limiting structure 413 can firmly fix the printing platform body 411 to one side of the first fixed seat, effectively preventing the printing platform body 411 from rotating during printing, thereby ensuring printing accuracy and quality. The preset position at this time is the position of the printing platform body 411 during printing; in this embodiment, the preset position during printing is a horizontal position. Furthermore, the second limiting structure 413 can also limit the rotation angle of the printing platform body 411 when cleaning accumulated liquid, preventing excessive rotation. The second limiting structure 413 has a limiting state and a releasing limiting state. It can be limited by snapping, abutting, magnetic attraction, insertion, etc., making it convenient to release the limit when rotation is needed, allowing the platform to rotate freely, and to enter the limiting state when fixation is needed, ensuring platform stability and flexible and convenient operation.

[0042] In some embodiments, such as Figure 3-4 As shown, the printer housing 1 is provided with an integrated liquid storage structure 301, which is connected to the cleaning tank 300. The integrated liquid storage structure 301 includes one or more liquid storage tanks 302 for storing cleaning fluid and a pipe structure for connecting the cleaning tank 300 and the liquid storage tanks 302.

[0043] By integrating the water tank with the printer housing 1, the inefficiency of frequent manual addition and pouring of cleaning fluid is solved, and the bulky size and space occupation caused by external fluid supply devices are avoided, resulting in a more compact overall layout of the 3D printer and improved space utilization. The liquid reservoir 302 can utilize gravity to allow the cleaning fluid to flow into the cleaning tank 300 through a pipe structure via a control switch; similarly, the cleaning fluid in the cleaning tank 300 can also be discharged directly outside the printer via gravity through a pipe structure via a control switch; alternatively, a pump structure can be added to allow the cleaning fluid to flow from the liquid reservoir 302 into the cleaning tank 300 through a pipe structure or back from the cleaning tank 300 into the liquid reservoir 302, achieving recycling. The liquid reservoir 302 enables the recycling of cleaning fluid, reducing the cost of using it. Furthermore, multiple liquid reservoirs 302 can be set up to achieve two-round, three-round, or multi-round cleaning to achieve the desired cleaning effect. Automated control of the circulation process reduces manual operation.

[0044] Furthermore, such as Figure 4 As shown, the liquid reservoir 302 is detachably mounted on the printer housing 1.

[0045] The liquid storage tank 302 is detachably positioned using a locking mechanism such as clips and a receiving slot, improving its flexibility and convenience, and facilitating independent cleaning and maintenance. Furthermore, when the cleaning fluid in the first-cycle storage tank 302 needs replacement after multiple cycles, the second-cycle tank can be directly swapped for the first cycle, maximizing the utilization of the cleaning fluid and further reducing cleaning costs. In addition, multiple storage tanks 302 can be installed to store different types of cleaning fluids, such as alcohol and acetone, allowing for easy replacement using the detachable structure to meet the cleaning needs of different printing materials, thus improving the equipment's versatility and adaptability.
