Abstract

A cutting device includes a guide extending in a vertical direction, a cutting mechanism that includes a cutting blade and that moves in the vertical direction along the guide, a drive device that moves the cutting mechanism in a horizontal direction by moving the guide in the horizontal direction, a pressing device that presses the cutting mechanism from above, and a reception base on which a cutting object is placed and that receives the cutting blade during the cutting movement. During cutting of the cutting object, the cutting mechanism pressed by the pressing device is moved downward along the guide and cuts the cutting object placed on the reception base with the cutting blade.

First claim

The invention claimed is:

1. A cutting device comprising:
a guide that extends in a vertical direction;
a cutting mechanism that includes a cutting blade and is configured to move in the vertical direction along the guide;
a drive device configured to move the guide in a horizontal direction, such that the cutting mechanism is moved in the horizontal direction;
a pressing device configured to press the cutting mechanism downward in the vertical direction;
a reception base configured to receive an object with an elongated shape and to receive the cutting blade during cutting of the object;
a cutting object feed device configured to feed the object in one direction;
a first clamp configured to clamp a first end side of a predetermined region including a cutting object portion of the object;
a second clamp configured to clamp a second end side of the predetermined region of the object; and
a clamp movement device configured to move the first and second clamps in a state of clamping the object when the object is fed in the one direction,
wherein the pressing device is configured to press the cutting mechanism downward along the guide to cut the object when placed on the reception base with the cutting blade.

2. The cutting device according to claim 1 , further comprising a support configured to support the pressing device, wherein a position of the cutting mechanism relative to the support in the horizontal direction is changed by movement of the guide by the drive device.

3. The cutting device according to claim 1 , wherein the one direction is parallel to the horizontal direction.

4. The cutting device according to claim 1 , wherein the clamp movement device is configured to adjust a movement speed of the first and second clamps, such that tension in the predetermined region of the object becomes substantially zero.

5. The cutting device according to claim 1 , further comprising a carrier film feed device configured to feed an elongated carrier film placed below the object to be cut.

6. The cutting device according to claim 4 , further comprising a static elimination device configured to perform static elimination of the object and the carrier film before the object overlaps with the carrier film.

7. The cutting device according to claim 1 , further comprising an imaging device configured to capture an image of the object to be cut before the cutting object feed device feeds the object in the one direction.

8. The cutting device according to claim 7 , wherein the drive device is configured to move the guide based on at least one of a position and an inclination of the object that is determined based on the captured image of the object.

9. The cutting device according to claim 8 , wherein the drive device is configured to move the cutting mechanism in the horizontal direction by moving the guide in at least one of an X-axis direction, a Y-axis direction, and a θ direction based on the at least one of the position and the inclination of the object.

10. The cutting device according to claim 9 , wherein the X-axis direction, the Y-axis direction, and the θ direction all extend in a plane parallel to the horizontal direction.

11. A method for cutting an object, the method comprising:
moving a guide, which extends in a vertical direction, in a horizontal direction to move a cutting mechanism in the horizontal direction that is coupled to the guide and that includes a cutting blade;
placing, on a reception base, an object having an elongated shape;
feeding the object in one direction;
clamping, by a first clamp, a first end side of a predetermined region including a cutting object portion of the object clamping, by a second clamp, a second end side of the predetermined region of the object;
moving, by a clamp movement device, the first and second clamps in a state of clamping the object when the object is fed in the one direction; and
pressing, by a pressing device, the cutting mechanism downward along the guide in the vertical direction to cut the object with the cutting blade when the object is placed on the reception base.

12. The method according to claim 11 , wherein the one direction is parallel to the horizontal direction.

13. The method according to claim 11 , further comprising, adjusting, by the clamp movement device, a movement speed of the first and second clamps, such that tension in the predetermined region of the object becomes substantially zero.

14. The method according to claim 11 , further comprising:
feeding, by a carrier film feed device, an elongated carrier film placed below the object to be cut; and
performing static elimination of the object and the carrier film before the object overlaps with the carrier film.

15. The method according to claim 11 , further comprising:
capturing an image of the object to be cut before feeding the object in the one direction; and
moving the guide based on at least one of a position and an inclination of the object that is determined based on the captured image of the object.

16. The method according to claim 15 , further comprising moving the cutting mechanism in the horizontal direction by moving the guide in at least one of an X-axis direction, a Y-axis direction, and a θ direction based on the at least one of the position and the inclination of the object.
