DETAILED DESCRIPTION

[0028] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0029] The terms “front”, “back”, “left”, “right”, “up” and “down” in this application are as per the attached Figure 1 Front, back, left, right, up and down shown.

[0030] An embodiment of the present application provides a vacuum curing box, which is used to post-process the surface of a 3D printed product so that the surface of the 3D printed product can be cured quickly and evenly.

[0031] like Figure 1As shown, the vacuum curing box 100 includes: a curing box body 1, a box cover 2 rotatably connected to the curing box body 1, a tray 3 rotatably set in the curing box body 1, and an ultraviolet curing lamp 4, an infrared heating device, a reflector 6 and a vacuum system set in the curing box body 1.

[0032] The curing box body 1 has a vacuum chamber 11 inside for accommodating 3D printed products, and the vacuum chamber 11 forms an opening 110 on the front side of the curing box body 1 for moving 3D printed products into and out of the vacuum chamber 11. The box cover 2 is rotatably connected to the opening 110 of the curing box body 1, and the box cover 2 opens and closes the vacuum chamber 11 during the rotation process.

[0033] like Figure 2-5 As shown, the curing box body 1 includes an outer shell 12 and an inner shell 15. The inner shell 15 defines a vacuum chamber 11. The outer shell 12 surrounds the outside of the vacuum chamber 11. A storage space 13 for accommodating components is formed between the outer shell 12 and the inner shell 15. The box cover 2 is hinged to the outer shell 12 by a pair of hinges 21. The tray 3 is arranged inside the vacuum chamber 11 and is rotatably set at the center of the bottom of the vacuum chamber 11. The tray 3 is used to hold the 3D printed products moved into the vacuum chamber 11. A plurality of ultraviolet curing lamps 4 are installed in the vacuum chamber 11 for emitting ultraviolet light into the vacuum chamber 11. The ultraviolet light is used to cure the unsolidified resin on the surface of the 3D printed products. The infrared heating device 5 is installed in the vacuum chamber 11 for increasing the temperature in the vacuum chamber 11 so that the 3D printed products can be dried as quickly as possible in the vacuum chamber 11. Multiple reflective plates 6 are fixedly mounted on the inner wall of the inner shell 15 and form the inner wall of the vacuum chamber 11 within the curing box body 1. Each reflective plate 6 has a reflective mirror surface that reflects the ultraviolet light emitted by the ultraviolet curing lamp and evenly covers the 3D printed product. The inner wall formed by the multiple reflective plates 6 reflects the light emitted by each ultraviolet curing lamp 4 onto the 3D printed product, ensuring uniform dispersion of the ultraviolet light. The vacuum system includes a suction port in fluid communication with the vacuum chamber 11 and a suction motor 7 disposed outside the vacuum chamber 11. The suction motor 7 is connected to the suction port, and suction pressure is applied to the suction port to extract air from the vacuum chamber 11 through the suction port. When the box cover 2 covers the opening 110 to close the vacuum chamber 11, the vacuum system continuously draws air from the vacuum chamber 11, thereby forming a vacuum environment within the vacuum chamber 11.

[0034] Multiple reflectors 6 are fixedly mounted on the inner wall surface of the inner shell 15 to form the bottom wall, top wall, left wall, right wall and rear wall of the vacuum chamber 11. The multiple reflectors 6 allow the reflected ultraviolet light to evenly cover the surface of the 3D printed product.

[0035] The tray 3 is in transmission connection with a driving device 8, which is arranged below the vacuum chamber 11 and between the inner shell 15 and the outer shell 12. The transmission shaft of the driving device 8 passes through the reflector 6 and the inner shell 15 at the bottom wall and is connected to the tray 3, thereby driving the tray 3 to rotate around an axis extending in the up-down direction. The tray 3 holds the 3D printed products and rotates in the vacuum chamber 11. On the one hand, it prevents the uncured resin on the surface of the 3D printed products from dripping into the vacuum chamber 11. On the other hand, it allows the 3D printed products to be evenly irradiated with ultraviolet light during the rotation process, ensuring that the surface of the 3D printed products is evenly and quickly cured. The tray 3 is detachably connected to the driving device 8. When too much resin accumulates in the tray 3, it can be removed from the curing box body 1 for cleaning.

[0036] like Figure 2 、 3 As shown, the UV curing lamp 4 includes a lamp holder 41 mounted on the top wall and a lamp post 42 detachably connected to the lamp holder 41. The lamp post 42 extends in the up-down direction, and a plurality of UV lamp beads 43 emitting UV light are mounted on the lamp post 42. The detachable connection between the lamp post 42 and the lamp holder 41 facilitates the replacement of the UV lamp beads 43 on the lamp post 42 when they are damaged. In the embodiment of the present application, two groups of UV curing lamps 4 are installed in the vacuum chamber 11. The two groups of UV curing lamps 4 are arranged opposite to each other on the left and right sides. Each group of UV curing lamps 4 includes a plurality of UV curing lamps 4. The left group of UV curing lamps 4 is adjacent to the left side wall and arranged in sequence along the front-to-back direction. The right group of UV curing lamps 4 is adjacent to the right side wall and arranged in sequence along the front-to-back direction, thereby avoiding obstruction of the 3D printed products from being moved into the vacuum chamber 11.

[0037] The infrared heating device 5 is located on the top wall of the vacuum chamber 11. When powered, it heats the interior of the vacuum chamber 11, raising the ambient temperature therein and, in conjunction with the ultraviolet light, accelerating the curing of the surface of the 3D-printed product. The infrared heating device 5 can be an infrared heating rod or an infrared heating net. A temperature detection device 51 is also provided within the vacuum chamber 11 for real-time monitoring of the temperature within the vacuum chamber 11.

[0038] The vacuum curing box 100 also includes a controller 10, which is signal-connected to two groups of ultraviolet curing lamps 4, infrared heating devices 5, temperature detection devices 51, suction motors 7 and drive devices 8. The controller 10 can receive signals transmitted by the temperature detection devices 51 and selectively control the operation of the ultraviolet curing lamps 4, infrared heating devices 5, suction motors 7 and drive devices 8.

[0039] like Figure 1 、 2As shown, because the UV curing lamp 4 emits ultraviolet light, which can be harmful to the human body if exposed to it for extended periods, the lid 2 of the present application is opaque. Furthermore, the curing chamber body 1 is provided with a detection switch 9, which is signal-connected to a controller 10. The detection switch 9 is located near the opening 110 and is configured to be triggered when it comes into contact with the lid 2. When the lid 2 closes the vacuum chamber 11, the detection switch 9 is triggered and sends a trigger signal to the controller 10, which then activates the UV curing lamp 4, infrared heating device 5, suction motor 7, and drive device 8. When the lid 2 opens the vacuum chamber 11, the detection switch 9 is deactivated, and the controller 10 deactivates the UV curing lamp 4, infrared heating device 5, suction motor 7, and drive device 8. When the operator opens the lid 2, the UV curing lamp 4 is deactivated, protecting the operator from UV light and ensuring their safety. A reflector 6 is also mounted on the inside of the lid 2, serving as the front wall of the vacuum chamber 11.

[0040] In order to improve the sealing performance of the vacuum chamber 11, a sealing ring 14 is provided on the curing box body 1. The sealing ring 14 is arranged around the opening 110. When the box cover 2 closes the vacuum chamber 11, the sealing ring 14 is sealed between the box cover 2 and the curing box body 1, thereby improving the sealing performance of the vacuum chamber 11. When the suction motor 7 is working, the vacuum chamber 11 can be evacuated faster, thereby improving work efficiency.

[0041] The curing box of the present application is equipped with multiple UV curing lamps, infrared heating devices and vacuum systems. The corresponding components can be selectively controlled to operate according to different 3D printed products, so that the vacuum curing box can be suitable for curing different 3D printed products.

[0042] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes.
