Applicable device and method for 3D printer to automatically identify initial position of curved surface

Abstract

The invention relates to the field of 3D printers, and in particular relates to a device and a method suitable for automatically recognizing a curved surface initial position by a 3D printer. The technical aim of the invention is realized by using the following technical schemes: the device suitable for automatically recognizing the curved surface initial position of the 3D printer comprises a worktable for placing a printing model, and a spray head for spraying a material to form a model on the worktable, and further comprises an X-axle bracket arranged above and parallel to the worktable, an X-axle movement device connected with the spray head, and a Z-axle movement device connected with the X-axle bracket and capable of enabling the X-axle bracket to slide in the vertical direction. The invention aims at providing the device and the method suitable for automatically recognizing the curved surface initial position by the 3D printer, partition multipoints of the printing spray head and the worktable are touched so as to obtain an initial Z0 position, not only is the inconvenience of manual regulation avoided, is the efficiency promoted, but also the printing on the curved surface can be realized.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a device and method suitable for 3D printers to automatically identify the initial position of a curved surface. Background technique [0002] 3D printers can quickly print out three-dimensional objects based on digital model files. They are intuitive to observe and easy to use. In recent years, they have become rapidly developed and widely used technical equipment around the world. The working principle of the 3D printer is to use the layer-by-layer printing method. The printing nozzle moves on the X-axis and Y-axis, the filament is sprayed on the working platform, and then the printing nozzle moves on the Z-axis through the lifting device, and the previous step is repeated to print. The model layer of this Z-axis height is extracted to obtain a three-dimensional physical model. In this process, the working platform needs to be precisely leveled, otherwise the Z-axis coordinates calc...

[0004] However, this adjustment method still does not change the status quo of needing to manually adjust the spring to level the working platform. If the temperature environment changes, the material of the platform will change. At the same time, the spring is in a contracted state for a long time, and the elastic coefficient will also change. It needs to be adjusted again; on the other hand, if there is an error in the flatness of the platform itself, no adjustment will solve the printing problem caused by the unevenness of the platform; finally, with the advancement of technology, sometimes users need the bottom of the model to be curved, A horizontal working plane is obviously not possible
