Description

Technical Field

[0001] This utility model relates to the field of material collection device technology, specifically a material collection device for a photopolymer 3D printer. Background Technology

[0002] A typical structure of a photopolymer 3D printer includes a platform lifting mechanism, a forming platform, a resin tank, a display screen, and a light source. The light source, through the display screen, creates a transmission area at the bottom of the resin tank to be cured. Liquid resin located on the forming surface of the forming platform or between the bottom of the cured layer and the bottom of the resin tank cures in this transmission area. During the layer-by-layer molding of a 3D object, the first cured layer needs to be reliably bonded to the forming surface of the forming platform. This requires precise adjustment of the forming platform before printing begins, ensuring that the forming surface of the platform is parallel to the bottom of the resin tank and has a suitable gap. After each layer is cured, the forming platform, driven by the platform lifting mechanism, moves up and down within the resin tank, causing the cured layer to detach from the bottom of the resin tank. Simultaneously, a space is left between the cured layer and the bottom of the resin tank to allow liquid resin to fill the gap between the cured layer and the bottom of the resin tank, preparing for the next layer to cure. To achieve good surface finish, the height positioning of each cured layer needs to be highly precise.

[0003] After the photopolymer 3D printer finishes printing the model, the staff needs to manually disassemble it one by one with auxiliary tools. After disassembly, the model is placed in the collection box. The entire disassembly and collection work is done manually by the staff, which is inefficient. The surface temperature of the newly printed model is high, which is not conducive to the disassembly work.

[0004] Therefore, after searching the existing technology, it was found that the currently disclosed patent technology, such as the material collection device for a photopolymer 3D printer proposed in publication number CN215620006U, works on the following principle: 1. The material collection box of this utility model is detachable through the cooperation of the slider and the guide plate. After the material collection box is full of models, the staff can replace it with a new material collection box in time. Through the setting of the material collection mechanism, the processed models fall into the material collection box efficiently and orderly. Compared with the conventional manual disassembly and collection method, the collection efficiency is greatly improved and the entire model collection is highly automated; 2. The universal wheels of this utility model facilitate the movement of the material collection box. The guide plate is closed on the side away from the material collection box to ensure that the model will not fall off from the opposite direction of the guide plate after it is formed. The buffer pad protects the model structure. The overall structure of the material collection mechanism is simple and compact. It is movable on the right side of the working machine box, which improves the overall mobility of the material collection mechanism.

[0005] However, in actual use, the collection box is not easy to position and clamp with the guide plate, which reduces the efficiency and effectiveness of the collection device, resulting in poor practicality. Summary of the Invention
