Abstract

A component supplying device supplying a component while using a component supply tape having components thereon includes a reel support portion rotatably supporting a reel around which the component supply tape is wound, a feeder transferring the component supply tape drawn out from the reel toward a component pick-up position and transferring the component supply tape from which the component is picked up at the component pick-up position S 1 toward a tape discharge path, and a correction member arranged on a transfer path of the component supply tape between the reel support portion and the tape discharge path. The correction member is configured to correct curl of the component supply tape.

First claim

The invention claimed is:

1. A feeder supplying components that are included in a component supply tape wound around a reel, the feeder comprising:
a body section having an elongated shape and including a tape inlet at a first end thereof and a tape outlet at a second end thereof with respect to a longitudinal direction thereof, the tape inlet and the tape outlet being continuous to outside of the feeder;
a first tape transfer mechanism disposed in the body section and near the first end of the body section;
a second tape transfer mechanism disposed in the body section and near the second end of the body section; and
a tape cavity extending through the body section from the tape inlet to the tape outlet, the tape cavity including a curved tape cavity in an end portion thereof and the curved tape cavity including the tape outlet, wherein
the first tape transfer mechanism transfers the component supply tape including a carrier tape having the components thereon and a top tape through the tape cavity to the second tape transfer mechanism,
the second tape transfer mechanism transfers a used component supply tape through the curved tape cavity to the tape outlet, the used component supply tape includes the carrier tape from which the components are picked up at a component pick-up position and the top tape, the component pick-up position is defined on a portion of the tape cavity above the second tape transfer mechanism,
the curved tape cavity is defined by a lower-side tape receiving member and an upper-side tape press member that are opposite each other while having a space therebetween,
the lower-side tape receiving member has a lower curved surface that faces upward and is recessed downward,
the upper-side tape press member has a curved surface that is opposite the lower curved surface and projects downward so as to extend along the lower curved surface, and
the space is defined by the lower curved surface and the curved surface and the lower-side tape receiving member and the upper-side tape press member of the curved tape cavity restrict the used component supply tape to travel within the space and along the lower curved surface and the curved surface.

2. The feeder according to claim 1 , wherein the curved tape cavity is located between the second tape transfer mechanism and the tape outlet.

3. The feeder according to claim 1 , wherein
the lower-side receiving member has a sloped surface that is inclined downward toward the tape outlet and includes the lower curved surface near the tape outlet, and
the upper-side tape press member has a sloped surface that extends along the sloped surface of the lower-side tape receiving member and includes the curved surface opposite the lower curved surface.

4. The feeder according to claim 1 , wherein the lower-side tape receiving member and the upper-side tape press member have a S-shape.

5. The feeder according to claim 1 , the lower-side tape receiving member and the upper-side tape press member are arranged such that outermost end portions thereof that form the tape discharge outlet are aligned with each other.

6. The feeder according to claim 1 , wherein the upper-side tape press member is a metal plate spring.

7. The feeder according to claim 1 , wherein the upper-side tape press member is a metal ball that is rotatably fixed to the end portion of the body section.

8. A component supplying device comprising:
the feeder according to claim 1 ; and
a reel support section rotatably supporting the reel.

9. A surface mounting device comprising:
the component supplying device according to claim 8 ;
a base mount where a board is disposed;
a component mounting device configured to mount the component that is picked up at the component pick-up position onto the board that is disposed on a component mount position of the base mount; and
a convey device configured to convey the board to the component mount position.
