Abstract

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.

Claims (37)

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.

2 . The three-dimensional laminate shaping device according to claim 1 , further comprising:

a second printing device including a second ejection head configured to eject metal ink, the second printing device configured to print a circuit material on the circuit board by ejecting the metal ink from the second ejection head,

wherein the multiple types of calibration marks include a second aligning mark, and

the control device is further configured to perform a calibration for aligning a second printing position of the second ejection head based on a second image of the second alignment mark.

3 . The three-dimensional laminate shaping device according to claim 1 , further comprising:

a first supply device configured to supply a first conductive adhesive onto the circuit board,

wherein the multiple types of calibration marks include a third aligning mark, and

the control device is further configured to perform a calibration for aligning a supply position of the first supply device based on a third image of the third alignment mark.

4 . The three-dimensional laminate shaping device according to claim 1 , further comprising:

a second supply device configured to supply a non-conductive adhesive onto the circuit board,

wherein the multiple types of calibration marks include a fourth aligning mark,

the control device is further configured to perform a calibration for aligning a supply position of the second supply device based on a fourth image of the fourth alignment mark.

5 . The three-dimensional laminate shaping device according to claim 1 , wherein

the first ejection head includes multiple nozzles, and

the jig includes a first abnormal nozzle detection region, and

the control device is further configured to detect a nozzle from which the structural material is not ejected in the multiple nozzles provided in the first ejection head based on an image of the first abnormal nozzle detection region.

6 . The three-dimensional laminate shaping device according to claim 2 , wherein

the second ejection head includes multiple nozzles, and

the jig includes a second abnormal nozzle detection region, and

the control device is further configured to detect a nozzle from which the metal ink is not ejected in the multiple nozzles provided in the second ejection head based on an image of the second abnormal nozzle detection region.

7 . The three-dimensional laminate shaping device according to claim 1 , wherein

the multiple types of calibration marks include a calibration mark for the camera.

8 . The three-dimensional laminate shaping device according to claim 1 , wherein

the multiple types of calibration marks include a jig tilt measurement mark for measuring tilt of the jig.

9 . The three-dimensional laminate shaping device according to claim 1 , wherein

the jig is formed of glass.
