Abstract

A gripping mechanism (3) includes a holder (31), a gripping roller (32), a first movable plate (331), a second movable plate (332), a first spring (341), and a second spring (342). The holder (31) houses the gripping roller (32). The first movable plate (331) and the second movable plate (332) pinch the gripping roller (32) inside the holder (31). The first spring (341) urges the first movable plate (331) toward the gripping roller (32). The second spring (342) urges the second movable plate (332) toward the gripping roller (32). The gripping mechanism (3) grips a gripped section (42) of a first component (4) between the first movable plate (331) and the gripping roller (32).

First claim

The invention claimed is:

1. A gripping mechanism comprising:
a roller;
a frame which houses the roller;
a first movable plate and a second movable plate which pinch the roller inside the frame;
a first elastic object configured to urge the first movable plate toward the roller; and
a second elastic object configured to urge the second movable plate toward the roller, wherein
the gripping mechanism grips an object between the first movable plate and the roller.

2. The gripping mechanism according to claim 1 , wherein
the frame has an opening which receives insertion of the object, and
in a periphery of the opening, the first movable plate and the second movable plate are each pivotably supported by the frame.

3. The gripping mechanism according to claim 1 , wherein
the second movable plate is inclined relative to a vertical direction and holds the weight of the roller.

4. The gripping mechanism according to claim 1 , wherein
the first elastic object has a first spring and the second elastic object has a second spring, and
the second spring is stronger than the first spring.

5. The gripping mechanism according to claim 1 , wherein
the frame has a side plate, and
the side plate has a cutout portion which allows passage of the object but not passage of the roller.

6. An assembly apparatus comprising:
the gripping mechanism according to claim 1 ; and
a driving mechanism configured to move the gripping mechanism relative to the object.
