[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a monitoring and feeding device for SLA photopolymerization 3D printing, such as... Figure 1-3 As shown, the SLA photopolymer 3D printing monitoring and feeding device includes: an SLA photopolymer 3D printer body 1, a material tank 2 provided on the photopolymer 3D printer body 1, a liquid level sensor 3 provided on the photopolymer 3D printer body 1 for monitoring the amount of photosensitive resin in the material tank 2; a storage box 4 provided on the rear outer wall of the photopolymer 3D printer body 1, the storage box 4 for storing photosensitive resin; a feeding mechanism assembled on the photopolymer 3D printer body 1, the feeding mechanism for feeding the photosensitive resin stored in the storage box 4 into the material tank 2; and a stirring mechanism assembled on the storage box 4, the stirring mechanism for stirring the photosensitive resin in the storage box 4.

[0021] In this embodiment, the device is first equipped with a controller of model STM32H743VIT6. The controller can control the entire device. When the photopolymer 3D printer body 1 is in use, it is connected via a Keyence... The IL-1000's level sensor 3 monitors the amount of photosensitive resin in the material tank 2. When the level sensor 3 detects that the amount of photosensitive resin in the material tank 2 is lower than the set amount, it sends a signal to the controller. The controller receives and recognizes the signal, then activates the replenishing mechanism to add photosensitive resin stored in the storage box 4 into the material tank 2. When the level sensor 3 detects that the amount of photosensitive resin in the material tank 2 reaches the corresponding amount, it sends a signal to the controller, which again receives and recognizes the signal, then closes the replenishing mechanism, stopping the addition of material to the material tank 2. This convenient and simple replenishment process provides convenience for operators. Furthermore, during use, the controller periodically activates the stirring mechanism to stir the photosensitive resin stored in the storage box 4, preventing sedimentation and improving the subsequent printing effect. The entire device automatically replenishes the photosensitive resin and stirs the stored resin to prevent sedimentation and improve the subsequent printing effect.

[0022] In a further preferred embodiment of this utility model, the feeding mechanism includes: a feeding pump 5 fixedly installed on the rear outer wall of the photopolymer 3D printer body 1; a bent pipe 6 fixedly installed on the storage box 4, the bent pipe 6 being connected to the feed end of the feeding pump 5, and a connecting pipe 7 being connected to the discharge end of the feeding pump 5; and a flexible hose 8 disposed on the photopolymer 3D printer body 1, the flexible hose 8 being connected to the connecting pipe 7, and the discharge end of the flexible hose 8 extending into the material trough 2.

[0023] In this embodiment, when the level sensor 3 detects that the amount of photosensitive resin in the material tank 2 is lower than the set amount of resin during actual use, the level sensor 3 sends a signal to the controller. The controller receives and recognizes the signal, and then the controller starts the feeding pump 5. The feeding pump 5 is a peristaltic pump. The photosensitive resin in the storage tank 4 is transported to the material tank 2 in sequence through the bend pipe 6, the feeding pump 5, the connecting pipe 7, and the hose 8. This realizes automatic replenishment according to actual needs, making feeding convenient and simple, and providing convenience for the staff.

[0024] In a further preferred embodiment of the present invention, the stirring mechanism includes: a servo motor 9 fixedly installed on the storage box 4; and a stirring frame 10 rotatably installed inside the storage box 4, wherein the output shaft of the servo motor 9 is connected to the top end of the stirring frame 10 via a coupling.

[0025] In this embodiment, after the photosensitive resin has been stored in the storage box 4 for a period of time, the servo motor 9 is started. Its output shaft drives the stirring rack 10 to rotate in the storage box 4 through the coupling. The rotation of the stirring rack 10 can fully stir the photosensitive resin in the storage box 4, so that the components in the photosensitive resin are evenly distributed, avoiding precipitation due to long-term storage. This ensures the stable quality of the photosensitive resin added to the material tank 2 from the storage box 4, and ultimately improves the effect and quality of SLA photopolymerization 3D printing products.

[0026] In a further preferred embodiment of the present invention, a transparent plate 11 is provided on the storage box 4, and a shielding mechanism is provided on the storage box 4 to shield the transparent plate 11.

[0027] In this embodiment, the transparent plate 11 provides an easy window for operators to visually observe the condition of the photosensitive resin inside the storage box 4. After viewing, the transparent plate 11 is blocked by a shielding mechanism to prevent the photosensitive resin from being exposed to light.

[0028] In a further preferred embodiment of the present invention, the shielding mechanism includes: two limiting frames 12 symmetrically fixedly installed on the storage box 4, the two limiting frames 12 being located on both sides of the transparent plate 11; and a baffle 13 slidably installed on the two limiting frames 12, the baffle 13 being used to shield the transparent plate 11.

[0029] In this embodiment, when it is not necessary to observe the condition of the photosensitive resin in the storage box 4, the operator only needs to push the baffle 13 so that it slides along the two limit frames 12 to the position that completely covers the transparent plate 11. At this time, the baffle 13 can effectively block external light from shining through the transparent plate 11 onto the photosensitive resin in the storage box 4, avoiding changes in the properties of the photosensitive resin due to prolonged exposure to light, and ensuring the stability of the quality of the photosensitive resin. When it is necessary to observe the remaining amount, state, and other information of the photosensitive resin, the operator slides the baffle 13 in the opposite direction to expose the transparent plate 11, and can then directly observe the internal condition through the transparent plate 11.

[0030] In a further preferred embodiment of the present invention, a first magnet 14 is fixedly installed at the bottom of the baffle 13, and a second magnet 15 is fixedly installed on the limiting frame 12. The second magnet 15 and the first magnet 14 are compatible and adsorbed.

[0031] In this embodiment, when the baffle 13 slides along the two limiting frames 12 to completely cover the transparent plate 11 to block light, the first magnet 14 at the bottom of the baffle 13 will attract each other with the second magnet 15 on the limiting frame 12, so that the baffle 13 can be stably held in the position of blocking the transparent plate 11 and will not be displaced due to slight external vibration or shaking, thereby ensuring effective protection of the photosensitive resin, preventing light from shining through the transparent plate 11 onto the photosensitive resin, avoiding the photosensitive resin from deteriorating due to light exposure, and ensuring the quality of the photosensitive resin.

[0032] In a further preferred embodiment of the present invention, a limiting plate 16 is fixedly installed on the top of the storage box 4. The limiting plate 16 is located above the baffle 13. The limiting plate 16 is used to limit the upward movement of the baffle 13, and a handle is provided on the baffle 13.

[0033] In this embodiment, when the operator slides the baffle 13 to open or close the transparent plate 11, the limiting plate 16 can effectively limit the upward movement of the baffle 13, preventing the baffle 13 from escaping the constraint of the limiting frame 12 due to excessive upward movement, and ensuring that the baffle 13 always slides stably within the predetermined track. At the same time, a scraper 17 is provided inside the photopolymer 3D printer body 1, which facilitates the cleaning of the photosensitive resin in the material tank 2.

[0034] In summary, compared with related technologies, this device can automatically replenish photosensitive resin and stir the stored resin to prevent precipitation, thereby improving the printing effect on subsequent products.

[0035] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
