Platform adjustment mechanism of photocuring 3D printer, and photocuring 3D printer

Abstract

The invention discloses a platform adjustment mechanism of a photocuring 3D printer, and the photocuring 3D printer. The platform adjustment mechanism comprises a base plate, a forming platform plate,a vertical moving assembly, a connecting piece and a platform adjusting assembly; a resin groove is formed in the base plate; the plane, facing the resin groove, of the forming platform plate is a forming face; the vertical moving assembly is connected with the forming platform plate and controls the forming platform plate to move in the vertical direction; the connecting piece is connected withthe vertical moving assembly and the forming platform plate; the platform adjusting assembly is arranged between the connecting piece and the forming platform plate, used for adjusting the forming platform plate to be parallel to the bottom face of the resin groove, and comprises a positioning ball head, a positioning compression piece, a fastening piece and a connecting rod, the side face, facingthe forming platform plate, of the connecting piece is provided with a first groove part, and the positioning ball head and the positioning compression piece are both arranged in the first groove part; and the positioning compression piece sleeves the positioning ball head, the connecting rod is connected with the positioning ball head and the forming platform plate, a through hole is formed in the connecting piece, and the fastening piece penetrates through the through hole to compress the positioning compression piece so as to compress the positioning ball head.

Description

technical field [0001] The invention relates to the technical field of photo-curing 3D printers, in particular to a platform adjustment mechanism of a photo-curing 3D printer and a photo-curing 3D printer. Background technique [0002] The light-curing 3D printer irradiates the liquid light-curable resin with ultraviolet light or other light sources in a specific wavelength range and triggers a photochemical reaction, so that the light-curable resin in the area irradiated by the light source is solidified from the liquid state, and the object to be formed can be obtained after curing layer by layer. [0003] The structure of a light-curing 3D printer generally includes a platform lifting mechanism, a molding platform, a resin tank, a display screen, and a light source. The liquid resin between the bottom of the resin tank is solidified and formed in the transmission area. In the process of forming a three-dimensional object layer by layer, the first formed solidified layer ...

AI Technical Summary

Problems solved by technology

The typical adjustment mechanism of the forming platform uses multiple leveling screws to level the forming platform, but the process of adjusting multiple leveling screws in sequence is complicated, and often requires repeated adjustments to obtain a better leveling effect , in some cases even cannot be completely leveled, it is not convenient for users to operate, and may affect the final printing effect
