Automatic leveling device and leveling method for fused deposition additive manufacturing

Abstract

The invention discloses an automatic leveling device and leveling method for fused deposition additive manufacturing, and belongs to the field of additive manufacturing. The problems that a printing platform of an existing 3D printer needs to be manually leveled by manual work, precision cannot be achieved, and efficiency is low are solved. A laser distance measuring sensor is used for measuring the distance between a nozzle and a printing platform, the measured distances of the four corners are fed back to a controller for calculation, the differences between the effective distances of the four position points and the target value are obtained, and according to the difference value and the screw pitch of screws, the the rotating speed direction and the needed rotating angle of a control motor can be obtained through calculation; and the controller controls a stepping motor for rotating the screws mounted on the four corners, the screws are matched with nuts for achieving up and down moving, and each point on the printing platform and the nozzle form the horizontal state. Automatic leveling of the printing platform is achieved, the printing precision and the printing efficiency areeffectively improved, and intelligence, automation and fool operation of the fused deposition additive manufacturing device are achieved.

Description

technical field [0001] The invention relates to an automatic leveling device and a leveling method for fused deposition additive manufacturing, and belongs to the field of additive manufacturing. Background technique [0002] Fused deposition additive manufacturing is one of the relatively mature fields in the field of additive manufacturing. However, most of the machines currently on the market lack automatic leveling devices. The gap between the nozzle and the printing plate is manually adjusted by the operator. On the one hand, the operator is required to have a certain professional quality, and at the same time, the operation results of different operators are different, so the adjusted gap and the gap deviation of the four corners are different, which affects the printing quality of the final part. Therefore, it is very necessary to provide an automatic leveling device and method for fused deposition additive manufacturing. Contents of the invention [0003] The pres...
