Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a sunken DLP surface exposure 3D printing device. Background Technology

[0002] Photosensitive resin 3D printing is currently the most popular 3D printing technology in industry, and it is widely used in many fields such as prototype model making, medical guide plates, and art figurines. Products made by this type of 3D printing have smooth surfaces, high precision, and excellent display effects.

[0003] A search revealed that Chinese Patent Publication No. CN116587598B discloses a DLP printer with a sinking printing function. The printer uses a sensing component to detect the amplitude of the oscillation of the liquid photosensitive resin when the DLP printer vibrates. A positioning component controls the rotation of the protective plates. The four sets of protective plates and the lower end face of the base suppress the oscillation of the liquid photosensitive resin and prevent splashing. Simultaneously, the sensing component converts and releases the energy within the liquid photosensitive resin during oscillation, reducing the time required for the liquid surface to stabilize and improving work efficiency.

[0004] However, the aforementioned patents still have some shortcomings: their devices are supported by support feet, which have poor stability, making the devices prone to tipping over and causing damage when placed. Furthermore, it is not convenient to adjust the distance between the devices and the ground, resulting in poor hygiene and inability to meet different height requirements, thus reducing the usability and flexibility of the devices. Therefore, it is necessary to design a sunken DLP surface exposure 3D printing device that can improve the stability of device placement and facilitate the adjustment of device height to meet different usage needs.

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Reference Figure 1-6A recessed DLP surface exposure 3D printing device includes a frame 1. A housing 2 is mounted on the outer surface of the frame 1. Grooves 3 are formed on both side walls of the housing 2. Adjustment grooves 16 are symmetrically formed on the inner walls of the grooves 3. An adjustment support mechanism 4 is provided on one side of each groove 3. The adjustment support mechanism 4 includes a first support plate 401 and a second support plate 402 fixedly connected to one side of the rear surface of the housing 2. A screw 403 is rotatably connected between the first support plate 401 and the second support plate 402. An adjustment plate 404 is threaded onto the outer surface of the screw 403. A rotating shaft 405 and a rotating shaft are rotatably connected to both ends of the adjustment plate 404, respectively. 406. A fixing plate 407 and a fixing plate 408 are symmetrically fixedly connected to one side of the adjusting plate 404. A servo motor 409 is fixedly connected to one side of the fixing plate 407. A rotating shaft 405 is fixedly connected to the output end of the servo motor 409. A servo motor 410 is fixedly connected to one side of the fixing plate 408. A rotating shaft 406 is fixedly connected to the output end of the servo motor 410. Support legs 411 are symmetrically fixedly connected to the outer surface of one side of both the rotating shaft 405 and the rotating shaft 406. A suction cup 412 is fixedly connected to the lower surface of the support leg 411. A knob 5 is fixedly connected to one end of the screw 403.

[0029] With this configuration, both servo motor 409 and servo motor 410 are powered by an external power source. The distance between the device and the ground can be adjusted by adjusting the support mechanism 4, which allows for easy adjustment of the device's height according to different usage requirements. The suction cup 412 enhances the connection between the device and the ground, thereby improving the device's placement stability and, to a certain extent, preventing the device from tipping over and causing damage, thus improving the device's safety.

[0030] A placement platform 6 is fixedly connected to one inner wall of the frame 1. A resin tank 7 is installed on the inner wall of the placement platform 6. A Z-axis adjustment mechanism 8 is provided on the side of the frame 1 near the resin tank 7. An optical control device 9 is provided on the upper surface of the frame 1. A molding platform 10 is fixedly connected to one side of the Z-axis adjustment mechanism 8. The Z-axis adjustment mechanism 8 includes a T-shaped slide 801 formed in the inner wall of the frame 1. A sliding plate 802 is slidably connected to the inner wall of the T-shaped slide 801. The molding platform 10 is fixedly connected to the sliding plate 802. The frame 1 is located near the sliding plate. An electric telescopic rod 803 is fixedly connected to one side of 802. The electric telescopic rod 803 is fixedly connected to the slide plate 802. The lower surface of the frame 1 is rotatably connected to casters 11 in a rectangular array. A storage slot 12 is provided on one side wall of the housing 2. A control panel 13 is rotatably connected to the inner wall of the storage slot 12. The control panel 13 is electrically connected to the optical control device 9. The rear surface of the housing 2 is provided with heat dissipation slots 14 in a linear array at equal intervals. A dustproof net 15 is fixedly connected to the inner wall of the heat dissipation slots 14.

[0031] With this setup, when a model needs to be printed, the housing 2 is opened and the resin liquid is poured into the resin tank 7. The model is then printed via the control panel 13. The electric telescopic rod 803 drives the slide plate 802 to slide downwards along the inner wall of the T-shaped slide 801. The slide plate 802 drives the forming platform 10 downwards into the resin tank 7. The Z-axis adjustment mechanism 8 lowers the forming platform 10 by one layer each time. The optical control device 9 projects onto the resin liquid, causing the resin liquid to solidify layer by layer. Thus, the printed model is formed layer by layer above the forming platform 10, achieving the purpose of sunken printing. Furthermore, during the printing process, the heat generated inside the equipment is discharged to the outside through the heat dissipation tank 14 and the dustproof net 15, preventing the internal temperature of the equipment from being too high and affecting the printing effect. It is convenient to use.

[0032] Working principle: After the equipment is moved to a certain position by the casters 11, when support is needed, the knob 5 is turned to drive the screw 403 to rotate. The rotation of the screw 403 drives the adjusting plate 404 to move up and down on its outer surface. The downward movement of the adjusting plate 404 drives the rotating shaft 405 and rotating shaft 406 to move up and down on the inner wall of the adjusting groove 16, thereby adjusting the position of the rotating shaft 405 and rotating shaft 406 according to the usage requirements. After the adjustment is completed, the servo motor 1 409 and servo motor 2 410 are started at the same time to make the rotating shaft 405 and rotating shaft 406 rotate in opposite directions. Thus, the rotating shaft 405 and rotating shaft 406 rotate on the inner wall of the adjusting groove 16 and drive the support legs 411 on both sides to rotate in opposite directions. The support legs 411 and suction cup 412 contact the ground. By pressing the suction cup 412, the equipment is tightly connected to the ground, improving the connection strength between the equipment and the ground, effectively improving the placement stability of the equipment, and facilitating the adjustment of the distance between the equipment and the ground, thereby meeting different usage requirements.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
