Abstract

The invention discloses automatic calibration equipment for the light intensity of a DLP (Digital Light Processing) printing equipment projector. The automatic calibration equipment comprises a base; the base is provided with a first cylindrical linear guide rail which moves along the X-axis direction, a first sliding platform, a second cylindrical linear guide rail which moves along the Y-axis direction, a second sliding platform, a mounting platform, a third cylindrical linear guide rail which moves along the Z-axis direction and a third sliding platform in sequence from bottom to top; an extending platform is arranged at a side edge of the base in front of the third sliding platform; the third sliding platform and the extending platform are provided with a projector and a light intensity sensor respectively; the projector and the light intensity sensor are connected with a system control board; a calibration method comprises the following steps: step (1) focusing and adjusting; step (2) determining calibration reference light intensity; step (3) collecting compensation mask gray level numerical value of the projector; step (4) generating a compensation mask; step (5) carrying out calibration. The automatic calibration equipment provided by the invention is reasonable in design, compact in structure, convenient to operate and good in stability and can effectively obtain the light intensity of the projector.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a DLP printing equipment projector light intensity automatic calibration equipment and a calibration method. Background technique [0002] 3D printing technology (also known as rapid prototyping) is a new manufacturing technology that emerged in the late 1980s. It uses modern means such as computers, lasers, precision transmission, and numerical control to realize rapid manufacturing of workpieces through layer-by-layer stacking of raw materials. This emerging manufacturing technology integrates computer-aided design and computer-aided manufacturing. First, the three-dimensional solid model drawn in advance is layered according to a certain thickness, and then the solidification and stacking of raw materials is completed through the cooperation of the motion control system and the optical system. The molding entity is not limited by the shape, and has the advantages of fast m...
