Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printing technology, specifically to a light source device for achieving high-precision 3D printing. Background Technology
[0002] Additive manufacturing, commonly known as 3D printing, integrates computer-aided design, materials processing and forming technologies. Based on digital model files, it uses software and CNC systems to layer specialized metallic, non-metallic, and medical biomaterials through methods such as extrusion, sintering, melting, photopolymerization, and spraying to create physical objects. Unlike traditional processing methods that involve removing raw materials, cutting, and assembling, additive manufacturing is a bottom-up approach that builds from scratch. This makes it possible to manufacture complex structural components that were previously impossible due to the constraints of traditional manufacturing methods.
[0003] However, when cleaning the material tank or replacing the resin, the material tank needs to be removed. After removing the material tank, the liquid photosensitive resin adhering to the printing platform will drip onto the light source device below. If it is not cleaned in time, it will cause damage to the light source device.
[0004] To address these issues, we designed a light source device for high-precision 3D printing. Utility Model Content
[0005] The purpose of this invention is to provide a light source device for achieving high-precision 3D printing, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a light source device for realizing high-precision 3D printing, including a 3D printer base. The top two sides of the 3D printer base are provided with sliding grooves. A slider is slidably connected inside each sliding groove. A rack is fixedly provided on one side of the slider. A gear meshes on the other side of the rack. A threaded screw is fixedly connected inside the gear. A connecting block is threadedly connected to the middle of the threaded screw. A lifting platform is fixedly connected to the other side of the two connecting blocks.
[0007] Furthermore, the 3D printer base has an internal cavity, and the lifting platform is slidably connected to the inside of the cavity.
[0008] Furthermore, a curing lamp is fixedly installed on the top of the lifting platform, and the curing lamp is electrically connected to an external power source.
[0009] Furthermore, each of the connecting blocks is fixedly provided with a mounting plate on its top, and one end of each mounting plate is fixedly connected to one side of the 3D printer base.
[0010] Furthermore, a material trough is fixedly connected to one side of both sliders, and the material trough is placed on top of the 3D printer base.
[0011] Furthermore, mounting slots are provided on both sides of the interior of the 3D printer base.
[0012] Furthermore, through slots are provided on both sides of the middle part of the 3D printer base, the connecting block is slidably connected in the through slots, and the other end of the through slots extends to the bottom of the 3D printer base.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by pulling the material trough out from the top of the 3D printer base, the sliders on both sides of the material trough will slide along with the material trough at the same time. The sliding of the sliders will drive the movement of the rack. When the rack moves, the teeth of the rack mesh with the teeth of the gear, thereby causing the gear to rotate. When the gear rotates, it will drive the threaded screw to rotate together, so that the connecting block of the threaded screw surface will drive the lifting platform and the curing lamp to descend into the cavity, thereby completing the storage of the curing lamp. Then, the staff will insert the baffle into the installation slot to prevent liquid photosensitive resin from dripping onto the surface of the curing lamp and causing damage to the curing lamp.
[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting an installation groove, the installation groove is set in order to facilitate the staff to insert the baffle into the inside of the installation groove to protect the curing lamp. When cleaning the liquid photosensitive resin, the liquid photosensitive resin will drip directly onto the surface of the baffle. After the liquid photosensitive resin solidifies, it can be cleaned by the staff. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a light source device for high-precision 3D printing, including a 3D printer base 1. The top of the 3D printer base 1 has grooves 2 on both sides. A slider 3 is slidably connected inside each groove 2. A rack 4 is fixedly installed on one side of the slider 3, and a gear 5 meshes with the other side of the rack 4. A threaded screw 6 is fixedly connected inside the gear 5. A connecting block 7 is threadedly connected to the middle of the threaded screw 6. A lifting platform 8 is fixedly connected to the other side of both connecting blocks 7. A cavity 9 is opened inside the 3D printer base 1, and the lifting platform 8... The slidable connection is inside the cavity 9. The top of the lifting platform 8 is fixedly equipped with a curing lamp 10, which is electrically connected to an external power source. The top of each connecting block 7 is fixedly equipped with a mounting plate 12. One end of each mounting plate 12 is fixedly connected to one side of the 3D printer base 1. One side of the two sliders 3 is fixedly connected to a material trough 11. The material trough 11 is placed on the top of the 3D printer base 1. The middle part of the 3D printer base 1 has through slots 14 on both sides. The connecting block 7 is slidably connected in the through slot 14. The other end of the through slot 14 extends to the bottom of the 3D printer base 1.
[0022] In practice, when cleaning the material tank 11, the material tank 11 is pulled out from the top of the 3D printer base 1. At the same time, the sliders 3 on both sides of the material tank 11 will slide along with the material tank 11. The sliding of the sliders 3 will drive the movement of the rack 4. When the rack 4 moves, the teeth of the rack 4 mesh with the teeth of the gear 5, thereby causing the gear 5 to rotate. When the gear 5 rotates, it will drive the threaded screw 6 to rotate together, so that the connecting block 7 connected to the threaded screw 6 will drive the lifting platform 8 and the curing lamp 10 to descend into the cavity 9 together, thereby completing the storage of the curing lamp 10. Then, the staff will insert the baffle into the installation slot 13 to prevent the liquid photosensitive resin from dripping onto the surface of the curing lamp 10 and causing damage to the curing lamp 10.
[0023] After the liquid photosensitive resin inside the material tank 11 is cleaned, the staff manually pushes the material tank 11 back. As the material tank 11 is pushed back to its initial position, the lifting platform 8 and the curing lamp 10 will slide out of the cavity 9 and return to their initial positions.
[0024] See Figure 1-4As shown, mounting slots 13 are provided on both sides of the interior of the 3D printer base 1.
[0025] In practice, the installation slot 13 is provided to facilitate the staff to insert the baffle into the installation slot 13 to protect the curing lamp 10. When cleaning the liquid photosensitive resin, the liquid photosensitive resin will drip directly onto the surface of the baffle. After the liquid photosensitive resin solidifies, it can be cleaned by the staff.
[0026] It should be noted that liquid photosensitive resin dripping onto the surface of the curing lamp 10 may damage the curing lamp 10. This is mainly because the photosensitive resin will cure rapidly under ultraviolet irradiation, and may stick to the surface of the curing lamp 10, affecting the normal light emission and heat dissipation of the curing lamp 10, or even causing physical damage to the curing lamp 10. Photosensitive resin is a material that can harden rapidly under ultraviolet irradiation. When liquid photosensitive resin is dropped onto the surface of the curing lamp 10, the resin will quickly solidify due to the ultraviolet light emitted by the curing lamp 10 itself, and may adhere to the surface of the curing lamp 10. The hard substance formed after the resin solidifies may block part of the light from the curing lamp 10, resulting in a decrease in the light intensity of the curing lamp 10 and affecting the curing effect. If the resin covers the lens or reflector of the curing lamp 10, it may also change the direction of light propagation, further affecting the performance of the curing lamp 10. In addition, the curing lamp 10 generates a certain amount of heat during operation, requiring good heat dissipation to maintain the stability and lifespan of the curing lamp 10. The resin adhering to the surface of the curing lamp 10 after solidification may hinder the heat dissipation of the curing lamp 10, causing the temperature of the curing lamp 10 to rise, accelerating the aging and damage of the curing lamp 10. The resin forms a strong adhesion to the surface of the curing lamp 10 during the curing process. When attempting to remove the resin, it may damage the surface or internal structure of the curing lamp 10. Furthermore, the hard substance formed after the resin solidifies may scratch or wear the lens or reflector of the curing lamp 10, reducing the optical performance of the curing lamp 10.
[0027] Working principle: When cleaning the material tank 11, the material tank 11 is pulled out from the top of the 3D printer base 1. At the same time as the material tank 11 is pulled out, the sliders 3 on both sides of the material tank 11 will slide together with the material tank 11. The sliding of the sliders 3 will drive the movement of the rack 4. When the rack 4 moves, the teeth of the rack 4 mesh with the teeth of the gear 5, thereby causing the gear 5 to rotate. When the gear 5 rotates, it will drive the threaded screw 6 to rotate together, thereby causing the connecting block 7 connected to the threaded screw 6 to drive the lifting platform 8 and the curing lamp 10 to descend into the cavity 9 together, thus completing the storage of the curing lamp 10. Then, the staff inserts the baffle into the mounting slot 13 to prevent liquid photosensitive resin from dripping onto the surface of the curing lamp 10 and causing damage to the curing lamp 10.
[0028] The mounting slot 13 is provided here to facilitate the staff to insert the baffle into the mounting slot 13 to protect the curing lamp 10. When cleaning the liquid photosensitive resin, the liquid photosensitive resin will drip directly onto the surface of the baffle. After the liquid photosensitive resin solidifies, it can be cleaned by the staff.
[0029] After the liquid photosensitive resin inside the material tank 11 is cleaned, the staff manually pushes the material tank 11 back. As the material tank 11 is pushed back to its initial position, the lifting platform 8 and the curing lamp 10 will slide out of the cavity 9 and return to their initial positions.
