[0001] This utility model relates to the field of light source adjustment components, and in particular to a COB-LED light source adjustment component for 3D printers. Background Technology
[0002] A COB-LED light source adjustment component for 3D printers is a part that can adjust and control parameters such as light intensity, wavelength, and heat dissipation of the COB-LED light source in 3D printers to ensure stable light source output and improve printing accuracy and quality. It mainly includes a current adjustment mechanism, a light intensity detection sensor, a heat dissipation structure, an optical lens and reflector assembly, and a control system. These parts work together to achieve precise control of the light source.
[0003] However, in existing technologies, the light-emitting characteristics of COB-LED light sources may lead to uneven light intensity distribution, with differences in light intensity in different areas, which affects the accuracy and quality of printed parts. In photopolymer 3D printing, this non-uniformity may cause different parts of the same slice to have inconsistent curing degrees, resulting in defects such as warping and deformation in the printed parts. Utility Model Content
[0004] The purpose of this invention is to address the problem that the inherent light-emitting characteristics of COB-LED light sources in the prior art may lead to uneven light intensity distribution and differences in light intensity in different areas, thereby affecting the accuracy and quality of printed parts. In photopolymer 3D printing, this unevenness may cause inconsistent curing degrees in different parts of the same slice, resulting in defects such as warping and deformation in the printed parts. Therefore, this invention proposes a COB-LED light source adjustment component for 3D printers.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a COB-LED light source adjustment component for a 3D printer, comprising a COB-LED light source body, a light source diffuser plate disposed below the COB-LED light source body, an adjustment mechanism fixedly connected to the side of the light source diffuser plate, the upper part of the adjustment mechanism being fixedly connected to the side of the COB-LED light source body, the adjustment mechanism comprising a first connecting plate and a second connecting plate, the first connecting plate being fixedly connected to the side of the light source diffuser plate, and a threaded sleeve being fixedly connected to the upper part of the first connecting plate, a threaded adjusting rod being threadedly connected inside the threaded sleeve, a second connecting shaft being fixedly connected to the upper part of the threaded adjusting rod, the second connecting plate being fixedly connected to the side of the COB-LED light source body, and the second connecting shaft being rotatably connected to the second connecting plate.
[0006] Preferably, a mounting frame is fixedly connected to the side of the light source diffuser, and the first connecting plate is fixedly connected to the side of the mounting frame.
[0007] Preferably, four No. 1 connecting plates are fixedly connected to the side of the mounting frame, and the four No. 1 connecting plates are evenly distributed on the side of the mounting frame.
[0008] Preferably, two inner connecting plates are fixedly connected to the upper part of the first connecting plate, the two inner connecting plates are symmetrically distributed on both sides of the threaded sleeve, and an outer connecting plate is slidably connected to the surface of the inner connecting plate. The outer connecting plate is fixedly connected to the bottom of the second connecting plate.
[0009] Preferably, a driving mechanism is fixedly connected to the upper part of the COB-LED light source body. The driving mechanism includes a fixed frame, a servo motor is fixedly connected to the surface of the fixed frame, and a first connecting shaft is fixedly connected to the output end of the servo motor. The first connecting shaft is rotatably connected to the surface of the COB-LED light source body.
[0010] Preferably, a drive gear is fixedly connected to the surface of the first connecting shaft, and a driven gear is fixedly connected to the upper part of the second connecting shaft, wherein the drive gear meshes with the driven gear.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, a servo motor drives the first connecting shaft to rotate, which in turn drives the drive gear to rotate. The drive gear then drives the driven gear and the second connecting shaft to rotate, ultimately driving the threaded adjusting rod to rotate. Under the rotation of the threaded adjusting rod, the threaded sleeve moves upward or downward, thereby driving the first connecting plate and the light source diffuser to move upward or downward. By adjusting the position of the light source diffuser, the light source of the COB-LED light source body can be adjusted. The servo motor enables precise position control, allowing for accurate adjustment of the height of the light source diffuser according to requirements, thus finely changing the distribution and intensity of the light source to meet the diverse lighting requirements in different scenarios.
[0013] 2. In this utility model, during the upward or downward movement of the adjustment mechanism and the light source diffuser, the inner connecting plate slides along the outer connecting plate, thereby limiting the movement of the adjustment mechanism and the light source diffuser, improving the stability of the movement of the light source diffuser, and facilitating stable adjustment of the light source of the COB-LED light source body.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1: As Figures 1-4As shown, this utility model provides a COB-LED light source adjustment assembly for a 3D printer, including a COB-LED light source body 1, a light source diffuser 2 disposed below the COB-LED light source body 1, an adjustment mechanism 3 fixedly connected to the side of the light source diffuser 2, and an upper part of the adjustment mechanism 3 fixedly connected to the side of the COB-LED light source body 1. The adjustment mechanism 3 includes a first connecting plate 31 and a second connecting plate 34. The first connecting plate 31 is fixedly connected to the side of the light source diffuser 2, and a threaded sleeve 32 is fixedly connected to the upper part of the first connecting plate 31. A threaded adjusting rod 33 is threadedly connected inside the threaded sleeve 32. A second connecting shaft 46 is fixedly connected to the upper part of the threaded adjusting rod 33. The second connecting plate 34 is fixedly connected to the side of the COB-LED light source body 1. The connecting shaft 46 is rotatably connected to the second connecting plate 34. A mounting frame is fixedly connected to the side of the light source diffuser 2. The first connecting plate 31 is fixedly connected to the side of the mounting frame. Four first connecting plates 31 are fixedly connected to the side of the mounting frame. The four first connecting plates 31 are evenly distributed on the side of the mounting frame. A drive mechanism 4 is fixedly connected to the upper part of the COB-LED light source body 1. The drive mechanism 4 includes a fixing frame 41. A servo motor 42 is fixedly connected to the surface of the fixing frame 41. A first connecting shaft 43 is fixedly connected to the output end of the servo motor 42. The first connecting shaft 43 is rotatably connected to the surface of the COB-LED light source body 1. A drive gear 44 is fixedly connected to the surface of the first connecting shaft 43. A driven gear 45 is fixedly connected to the upper part of the second connecting shaft 46. The drive gear 44 and the driven gear 45 mesh.
[0022] The specific settings and functions of this embodiment are described below. The COB-LED light source body 1 emits light. During use, when the dispersion of the light source needs to be adjusted, the servo motor 42 drives the first connecting shaft 43 to rotate, which in turn drives the drive gear 44 to rotate. The drive gear 44 then drives the driven gear 45 and the second connecting shaft 46 to rotate, ultimately driving the threaded adjustment rod 33 to rotate. The rotation of the threaded adjustment rod 33 causes the threaded sleeve 32 to move upwards or downwards, which in turn drives the first connecting plate 31 and the light source diffuser 2 to move upwards or downwards. By adjusting the position of the light source diffuser 2, the light source of the COB-LED light source body 1 can be adjusted. The servo motor 42 enables precise position control, allowing for accurate adjustment of the height of the light source diffuser 2 according to requirements, thereby finely changing the distribution and intensity of the light source to meet the diverse lighting requirements of different scenarios.
[0023] Example 2: Figure 1 , Figure 2 and Figure 3As shown, two inner connecting plates 35 are fixedly connected to the upper part of the first connecting plate 31. The two inner connecting plates 35 are symmetrically distributed on both sides of the threaded sleeve 32. An outer connecting plate 36 is slidably connected to the surface of the inner connecting plate 35. The outer connecting plate 36 is fixedly connected to the bottom of the second connecting plate 34.
[0024] The overall effect of this embodiment is that, during the upward or downward movement of the adjustment mechanism 3 and the light source diffuser 2, the inner connecting plate 35 slides along the outer connecting plate 36, thereby limiting the movement of the adjustment mechanism 3 and the light source diffuser 2, improving the stability of the movement of the light source diffuser 2, and facilitating the stable adjustment of the light source of the COB-LED light source body 1.
[0025] The usage method and working principle of this device are as follows: The COB-LED light source body 1 emits light. During use, when it is necessary to adjust the dispersion of the light source, the servo motor 42 drives the first connecting shaft 43 to rotate, which in turn drives the drive gear 44 to rotate. The drive gear 44 then drives the driven gear 45 and the second connecting shaft 46 to rotate, which in turn drives the threaded adjusting rod 33 to rotate. Under the action of the rotation of the threaded adjusting rod 33, the threaded sleeve 32 moves up or down, which in turn drives the first connecting plate 31 and the light source diffuser 2 to move up or down. By adjusting the position of the light source diffuser 2, the purpose of adjusting the light source of the COB-LED light source body 1 is achieved.
[0026] During the upward or downward movement of the adjustment mechanism 3 and the light source diffuser 2, the inner connecting plate 35 slides along the outer connecting plate 36, thereby limiting the movement of the adjustment mechanism 3 and the light source diffuser 2.
[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
