Three-dimensional laminate shaping device
A three-dimensional laminate shaping device includes calibration jig in which multiple types of calibration marks are provided on the same surface. In this way, in three-dimensional laminate shaping device, using calibration jig in which multiple types of calibration marks are provided on the same surface makes it possible to perform multiple types of calibration with one jig.
1 . A three-dimensional laminate shaping device comprising:
a base plate movable in an X-direction and a Y-direction, an upper surface of the base plate configured to hold a circuit board via grippers that hold edges of the circuit board;
a first printing device including a first ejection head configured to eject a structural material, the first printing device being configured to laminate the structural material on the circuit board by discharging the structural material from the first ejection head;
a jig fixed on the upper surface of the base plate outside of a position of the circuit board held by the grippers, the jig including multiple types of calibration marks printed on a same surface of the jig, the multiple types of calibration marks including a first aligning mark;
a camera configured to image the jig and an upper side of the circuit board; and
a control device configured to
move the first ejection head to correspond to the first aligning mark,
instruct the first ejection head to eject a dot of the structural material on the jig,
instruct the camera to image a first calibration region including the dot and the first aligning mark,
measure a deviation amount of the dot and the first aligning mark based on the image, and
perform a calibration for aligning a first printing position of the first ejection head based on the deviation amount.
