[0045] 3D printing technology, also known as additive manufacturing, is a process of building three-dimensional objects by layering materials, and it has shown great potential in improving production efficiency, reducing costs, enabling complex designs, and driving innovation. 3D printing technology has been widely applied in various industries such as healthcare, manufacturing, construction, art design, education, and automotive manufacturing, bringing more innovation and change to various industries. For example, in the medical field, 3D printing technology can be used to make customized human organ models, prosthetics, orthotics, and even in the field of bioprinting to print tissues and organs, allowing doctors to plan and practice operations, improving surgical success rates and patient safety. In the manufacturing industry, 3D printing technology improves product development and manufacturing efficiency through rapid prototyping, personalized production, and batch customization. In the construction industry, 3D printing technology can quickly manufacture building components, achieve complex designs, and use renewable materials to reduce environmental impact. In the field of art design, 3D printing technology provides unlimited creativity for artists and designers, enabling them to create unique works of art, furniture, and jewelry, etc. In the field of education, 3D printing technology provides an intuitive learning experience and practical operation, stimulating students' interest in learning and creativity. In the automotive industry, 3D printing technology is used to quickly manufacture automotive parts and tools, improving the flexibility and efficiency of automobile manufacturing.

[0046] A 3D printer is a device that uses 3D printing technology to produce three-dimensional objects. Its working principle generally includes the following steps: first, create or import a digital model through computer-aided design (CAD) software; then, use slicing software to slice the model into thin slices; then, position the slices on the working platform of the 3D printer; then, the 3D printer stacks materials layer by layer according to the slicing information to build a solid object; finally, according to the needs, the product is post-processed, such as removing support materials, spraying coatings, etc. The light machine of a 3D printer generally refers to the light source system used in the light curing 3D printing technology, which is responsible for providing energy to cure photosensitive resin, thereby building a 3D object layer by layer. During the curing operation of the 3D printer, it is necessary to ensure that the light emitted by the light machine is perpendicular, thereby ensuring the accuracy of 3D printing, so the current 3D printers all need to set up an angle adjustment device to adjust the angle of the light machine. However, most of the existing angle adjustment devices need to be manually leveled, which is more troublesome and not very convenient, and the accuracy of the adjustment is limited, thereby affecting the product quality.

[0047] Therefore, the present application provides an angle adjustment device, a 3D printer and a corresponding light machine angle adjustment method, which can realize electric adjustment of the angle of the light machine, without the need for manual leveling by the operator, improving the convenience of operation, and compared with manual adjustment, electric adjustment can effectively improve the accuracy of adjustment, thereby ensuring product quality.

[0048] ReferenceFigure 1 And Figure 2 An embodiment of the present application provides an angle adjusting device for adjusting the angle of a light engine of a 3D printer, comprising a mounting mechanism 1 and an adjusting mechanism 2.

When the light engine 5 is mounted on the mounting seat 12, the lens of the light engine 5 can pass through the mounting seat 12 and the through hole 13 in sequence, so that when the adjusting mechanism 2 adjusts the angle of the light engine 5, the lens of the light engine 5 can be deflected in the through hole 13, so that the mounting platform 11 and the mounting seat 12 do not affect the adjustment of the angle of the light engine 5.

[0050] Referring to Figure 1 And Figure 2 The adjusting mechanism 2 comprises a first driving assembly 21 and a second driving assembly 22, and the first driving assembly 21 is arranged on the mounting platform 11.

The mounting seat 12 is arranged on the second driving assembly 22 and can rotate around the Y-axis under the driving of the second driving assembly 22, so as to adjust the angle around the Y-axis between the axis of the lens of the light engine 5 and the printing platform of the 3D printer.

That is, in the embodiments of the present application, the axial direction of the motor shaft of the first driving motor 212 is parallel to the Y direction, and the first driving motor 212 and the first arc-shaped slide 213 can be arranged on different sides of the first support 211, thereby reducing the height of the adjusting mechanism 2 along the Z direction, so that the adjusting mechanism 2 can be miniaturized.
