Cutting device and cutting method

摘要

A cutting device includes: an imaging module for capturing first marks and third marks, to produce primary image data; and a control module for aligning, by a conveyance mechanism, a cutting jig and an object to be cut that is placed on the cutting jig. The control module compares first positional information including positional information of a specific first mark stored or first positional information with third positional information to calculate a primary displacement amount showing a relative positional displacement between a plurality of cutting grooves and the plurality of third marks, respectively. The conveyance mechanism picks up the object from the cutting jig, and the conveyance mechanism and the cutting jig are moved relative to each other based on the primary displacement amount, to move the object by the primary displacement amount to a primary target position. The cutting mechanism cuts the object along a plurality of cutting lines.

主权项

1. A cutting device used when manufacturing a plurality of products by cutting an object to be cut, the cutting device comprising:
a cutting jig having a plurality of first marks and a plurality of cutting grooves and on which an object to be cut is placed, the object having a plurality of second marks and a plurality of third marks formed of a plurality of external electrodes; a cutting mechanism for cutting the object, which is placed on the cutting jig, along a plurality of cutting lines; a conveyance mechanism for conveying the object; a movement mechanism for moving the cutting jig and the cutting mechanism relative to each other; an imaging module for capturing at least the plurality of first marks and the plurality of third marks, to produce primary image data; and a control module for causing the conveyance mechanism to align the cutting jig and the object that is placed on the cutting jig, wherein the control module is adapted to compare (a) first positional information including positional information of a specific first mark stored or (b) first positional information including positional information of a specific first mark obtained by image-processing the primary image data, with third positional information including positional information of a specific third mark measured based on the primary image data, to calculate a primary displacement amount showing a relative positional displacement between the plurality of cutting grooves and the plurality of third marks, respectively, the conveyance mechanism is adapted to move the object to a primary target position depending on the primary displacement amount by means that the object is picked up from the cutting jig and the conveyance mechanism and the cutting jig are moved relative to each other based on the primary displacement amount, and then again place the object on the cutting jig, and the cutting mechanism is adapted to cut the object, which is placed again, along the plurality of cutting lines.
