Abstract

In a tape feeder which serves as a component supply device which is used for supplying components in a component mounter, a first unit which serves as a tape feed unit which pitch feeds a carrier tape which holds components to a component suction position using a pitch feeding sprocket drive mechanism, and a third unit and a second unit which serve as a tape supply unit which is attachable and detachable in relation to the tape feed unit and which supplies the carrier tape to the tape feed unit are selectively used according to the supply mode of the carrier tape to be used.

First claim

What is claimed is:

1. A component supply device comprising:
a first unit which pitch feeds components to a component suction position; and
a second unit which supplies a carrier tape which stores the components and is covered by a cover tape to the first unit,
wherein the first unit includes
a first unit tape guideway which guides the carrier tape to the component suction position,
a first unit sprocket drive mechanism which feeds the carrier tape to the component suction position by causing a sprocket to rotate in a state in which feed pins of the sprocket are caused to mesh with sprocket holes of the carrier tape, and
a component exposing member for exposing a portion of the cover tape, wherein the second unit includes
a second unit tape guideway into which the carrier tape is inserted and which feeds the carrier tape to the first unit, and

wherein the second unit is attached to be attachable and detachable in relation to the first unit.

2. The component supply device of claim 1 ,
wherein it is possible to exchange the second unit for a third unit which supplies the carrier tape to the first unit,
wherein the third unit includes
a third unit tape guideway into which the carrier tape is inserted and which feeds the carrier tape to the first unit, and
a third unit sprocket drive mechanism which feeds the carrier tape to the first unit by causing the sprocket to rotate in a state in which the feed pins of the sprocket are caused to mesh with the sprocket holes of the carrier tape, and

wherein the third unit is attached to be attachable and detachable in relation to the first unit.

3. The component supply device of claim 1 , wherein the first unit is located downstream from the second unit along the feeding of the carrier tape.

4. The component supply device of claim 1 , wherein:
the first unit tape guideway of the first unit includes a tape receiving surface in the vicinity of the component suction position and a recessed portion provided in the tape receiving surface, and
a first splicing tape is bonded to the carrier tape such that a width of the first splicing tape is smaller than a width of a recessed portion.

5. The component supply device of claim 4 , wherein:
the first splicing tape is bonded to a bottom surface of the carrier tape,
a second splicing tape is bonded to a top surface of the carrier tape, and
the second splicing tape is bonded to a portion of top surface which does not impede a peeling off operation of the cover tape by a blade of the component exposing member.

6. The component supply device of claim 1 , wherein:
the first unit includes a main body frame, and
the first unit tape guideway extends through the main body frame of the first unit.

7. The component supply device of claim 1 , wherein:
the second unit includes a main body frame, and
the second unit tape guideway extends through the main body frame of the second unit.

8. The component supply device of claim 1 , wherein:
the first unit includes a first locking portion; and
the second unit includes a second locking portion that is engageable with the first locking portion to attach the second unit to the first unit.

9. The component supply device of claim 1 , wherein it is possible to exchange the second unit for a third unit which supplies the carrier tape to the first unit, wherein the third unit includes:
a third unit tape guideway into which the carrier tape is inserted and which feeds the carrier tape to the first unit,
a third unit sprocket drive mechanism which feeds the carrier tape to the first unit by causing the sprocket to rotate in a state in which the feed pins of the sprocket are caused to mesh with the sprocket holes of the carrier tape, and
a third locking portion which is engageable with the first locking portion of the first unit to removable attach the third unit to the first unit.
