Description

Workbench for large-scale 3D printing equipment

Technical Field

The invention relates to the technical field of additive manufacturing, in particular to a workbench for large-scale 3D printing equipment, which is suitable for photocuring three-dimensional printing equipment.

Background

The 3D printing equipment is also called a three-dimensional printer, is a material increase manufacturing technology, namely a machine of a rapid prototyping technology, and is a technology which is based on a digital model file, applies a special adhesive material such as wax, powdered metal or plastic and the like, and manufactures a three-dimensional object by printing a plurality of layers of adhesive materials.

The photocuring three-dimensional printing (SLA) technology is one of plastic 3D printing, and adopts a digital light processing technology to cure liquid photosensitive resin layer by layer. At present, a three-dimensional object is usually manufactured on a workbench, a screen plate of a 3D printer is generally used as the workbench of the device, the flatness and stability of the screen plate directly influence the printing quality and precision of the object, the traditional screen plate mode is that a mesh plate is welded on a mesh plate frame, and once the area of the screen plate is increased, the flatness and stability of the surface of the screen plate are difficult to ensure.

Disclosure of Invention

In order to solve the technical problem, a workbench for large-scale 3D printing equipment is provided, the workbench is reasonable in structural design, a bracket is additionally arranged below a screen plate, weight-reducing holes for reducing weight and a forklift position for taking the screen plate by a forklift are also arranged on the side face of the workbench, the stability of the screen plate can be guaranteed, the screen plate is not deformed, and meanwhile, when large-scale parts are printed, the screen plate can be taken down from the forklift position by the forklift, so that the labor intensity of workers is reduced.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the workbench for the large-scale 3D printing equipment comprises a screen plate and a bracket fixedly provided with the screen plate, wherein the screen plate is square and is provided with a plane and a plurality of grids uniformly and fixedly arranged below the plane, a plurality of screw holes are uniformly formed in the edge of the screen plate, and the screen plate is fixed on the bracket through a fastening structure.

Furthermore, the bracket comprises four vertical plates vertically arranged on the edge grid of the screen plate and at least one middle vertical plate vertically arranged on the central axis of the screen plate, the edge of the screen plate is uniformly provided with a plurality of screw holes, the screen plate is fixed on the vertical plates and the middle vertical plates through screws, and the vertical plates and the middle vertical plates are fixedly connected through a plurality of connecting pieces.

Furthermore, a plurality of lightening holes are uniformly formed in the center of the vertical plate.

Furthermore, each opposite vertical plate is also uniformly provided with at least two forklift holes in a penetrating manner, and the forklift holes are close to the surface of the screen plate.

Furthermore, the cross section of the forklift hole is U-shaped.

Further, the connecting piece is a connecting block.

Furthermore, a plurality of through holes are uniformly formed in the vertical plate and the middle vertical plate.

Furthermore, the net plate is square or rectangular, and a plurality of through holes are uniformly arranged on the net plate.

Further, the grid is a reinforcing rib.

Through the technical scheme, the workbench for the large-scale 3D printing equipment is additionally provided with the bracket below the screen plate, the side surface of the workbench is also provided with the lightening holes for lightening and the forklift position for taking the screen plate by the forklift, so that the stability of the screen plate can be ensured, the deformation is avoided, and meanwhile, when large-scale parts are printed, the screen plate can be taken down from the forklift position by the forklift, so that the labor intensity of workers is reduced.
