Abstract

A lamination device that laminates a plurality of types of workpieces includes a plurality of supply mechanisms that supply a workpiece to each of a plurality of supply positions, a movement mechanism including a stator of a linear motor having a predetermined traveling track and a mover of a linear motor that is movable between a plurality of the supply positions along a traveling track, and a control unit that controls at least the mover. The mover includes a lamination stage for laminating the workpiece. The control unit corrects a relative position of the workpiece supplied to the supply positions with respect to the lamination stage, laminates the workpiece whose relative position is corrected on the lamination stage, and controls the mover so as to move to a next one of the supply positions after lamination of the workpiece.

First claim

What is claimed is:

1. A lamination device that is configured to laminate a plurality of types of workpieces, the lamination device comprising:
a plurality of supply mechanisms configured to supply the workpiece to each of a plurality of supply positions;
a movement mechanism including a stator of a linear motor having a predetermined traveling track and a mover of a linear motor movable between a plurality of the supply positions along the traveling track, the mover including a lamination stage configured to laminate the workpieces; and
a controller configured to control at least the mover,
the controller is configured to correct a relative position of the workpiece supplied to the supply position with respect to the lamination stage of the mover, configured to laminate the workpiece whose relative position is corrected on the lamination stage, and configured to control the mover to move to a next one of the supply positions after laminating the workpiece, and
the controller is configured to raise the lamination stage and control a raising amount of the lamination stage based on a number of the laminated workpieces laminated on the lamination stage.

2. The lamination device according to claim 1 , wherein
the controller is configured to move the lamination stage of the mover in order to correct a relative position of the workpiece with respect to the lamination stage.

3. The lamination device according to claim 2 , further comprising:
an imaging device configured to image the workpiece supplied by the supply mechanism, wherein
the controller is configured to move the lamination stage of the mover based on an image of the workpiece captured by the imaging device.

4. The lamination device according to claim 1 , further comprising:
an imaging device configured to image the workpiece supplied by the supply mechanism, wherein
the controller is configured to correct a relative position of the workpiece with respect to the lamination stage by performing:
first control of determining the supply position based on an image of the workpiece captured by the imaging device and controlling the supply mechanism so that the workpiece stops at the supply position that is determined,
second control of determining a stop position of the mover based on the image of the workpiece captured by the imaging device and controlling the mover so as to stop at the stop position that is determined, and
third control of controlling the lamination stage based on the image of the workpiece captured by the imaging device.

5. The lamination device according to claim 1 , wherein
a number of the movers is twice a number of the supply mechanisms.

6. The lamination device according to claim 1 , wherein
a number of the movers is the same as a number of the supply mechanisms.

7. The lamination device according to claim 1 , further comprising:
a jig supply and discharge mechanism configured to supply a jig for laminating the workpiece on the lamination stage and configured to discharge the jig together with a plurality of types of the workpieces for which lamination is completed.

8. The lamination device according to claim 7 , wherein
the lamination stage includes a fixing member configured to fix the jig.

9. The lamination device according to claim 8 , wherein
the fixing member is a positioning pin that is configured to fit to and separate from a recess in the jig.

10. The lamination device according to claim 2 , wherein
a number of the movers is twice a number of the supply mechanisms.

11. The lamination device according to claim 3 , wherein
a number of the movers is twice a number of the supply mechanisms.

12. The lamination device according to claim 4 , wherein
a number of the movers is twice a number of the supply mechanisms.

13. The lamination device according to claim 2 , wherein
a number of the movers is the same as a number of the supply mechanisms.

14. The lamination device according to claim 3 , wherein
a number of the movers is the same as a number of the supply mechanisms.

15. The lamination device according to claim 4 , wherein
a number of the movers is the same as a number of the supply mechanisms.

16. The lamination device according to claim 2 , further comprising:
a jig supply and discharge mechanism configured to supply a jig for laminating the workpiece on the lamination stage and configured to discharge the jig together with a plurality of types of the workpieces for which lamination is completed.

17. The lamination device according to claim 3 , further comprising:
a jig supply and discharge mechanism configured to supply a jig for laminating the workpiece on the lamination stage and configured to discharge the jig together with a plurality of types of the workpieces for which lamination is completed.

18. The lamination device according to claim 4 , further comprising:
a jig supply and discharge mechanism configured to supply a jig for laminating the workpiece on the lamination stage and configured to discharge the jig together with a plurality of types of the workpieces for which lamination is completed.

19. The lamination device according to claim 5 , further comprising:
a jig supply and discharge mechanism configured to supply a jig for laminating the workpiece on the lamination stage and configured to discharge the jig together with a plurality of types of the workpieces for which lamination is completed.

20. The lamination device according to claim 6 , further comprising:
a jig supply and discharge mechanism configured to supply a jig for laminating the workpiece on the lamination stage and configured to discharge the jig together with a plurality of types of the workpieces for which lamination is completed.

21. A lamination device that is configured to laminate a plurality of types of workpieces, the lamination device comprising:
a plurality of supply mechanisms configured to supply the workpiece to each of a plurality of supply positions;
a movement mechanism including a stator of a linear motor having a predetermined traveling track and a mover of a linear motor movable between a plurality of the supply positions along the traveling track, the mover including a lamination stage configured to laminate the workpieces;
a jig supply and discharge mechanism configured to supply a jig for laminating the workpiece on the lamination stage and configured to discharge the jig together with a plurality of types of the workpieces for which lamination is completed; and
a controller configured to control at least the mover, and
