Abstract

The invention provides a component supply device which is small and can supply electronic components efficiently. The component supply device 1 mounts a component supply tape T and exposes the electronic components out of the component supply tape T to provide to a component installation device 7 which mounts the electronic components on a circuit board. The component supply device 1 has a replenishment device 2 which replenishes a new component supply tape (Tb) when a preceding component supply tape Ta runs out, and a sensor S which detects the run-out of the preceding component supply tape Ta. The replenishment device 2 has a reel holding section 21 on which reels 20 wound with the component supply tape T are inserted, and a standby section 5 of the component supply tape T. When the sensor S detects that the preceding component supply tape Ta runs out and issues a detection signal, the component supply tape T is moved from the standby section to be replenished.

First claim

What is claimed is:

1. A component supply device that mounts a component supply tape and exposes an electronic component from the component supply tape to supply the electronic component to a component installation device that mounts the electronic component on a circuit board, the component supply device comprising:
a replenishment device that replenishes a new component supply tape when a preceding component supply tape runs out;
a feeding device that feeds the new component supply tape replenished by the replenishment device; and
a sensor that detects run-out of the preceding component supply tape, wherein
the replenishment device has a reel holding section on which a first reel wound with the preceding component supply tape and a second reel wound with the new component supply tape are inserted, and a standby section that makes the new component supply tape standby in a state of being wound on the second reel,
the standby section has a feeding mechanism that feeds the new component supply tape unreeled from the second reel, a base for supporting the feeding mechanism, and a controller that controls and drives the feeding mechanism,
the feeding mechanism has a feeding gear, the feeding gear is disposed at a position where the feeding gear is engaged with the new component supply tape wound on the second reel,
the feeding gear rotates about a pivot member fixed to the base,
the standby section has a partition that covers a first feeding path for feeding the new component supply tape from the reel holding section to the installation device,
the partition separates the first feeding path from a second feeding path for feeding the preceding component supply tape to the installation device,
the feeding gear is provided on the first feeding path and engaged with the new component supply tape,
the partition and the feeding gear are arranged to face each other across the new component supply tape, and
the controller is operable, when the sensor detects the run-out of the preceding component supply tape and generates a detection signal, to drive the feeding gear to allow the new component supply tape to be moved from the standby section to the installation device, as a control of replenishing the new component supply tape.

2. The component supply device according to claim 1 , wherein
the replenishment device has a separator that separates the preceding component supply tape from the new component supply tape in addition to the reel holding section and the standby section, and
the new component supply tape stands by at the standby section displaced in a longitudinal direction with respect to the preceding component supply tape in the replenishment device.

3. The component supply device according to claim 2 , wherein
the first feeding path is formed to have a width of the new component supply tape and has a guide groove in which the new component supply tape is movably inserted; and
the partition is a lid member that is arranged on the guide groove having the new component supply tape therein; and wherein
the lid member is detachably provided on the first feeding path.

4. The component supply device according to claim 1 , wherein
the reel holding section has a box-shaped tape housing that is arranged in a plurality of stages in an up-down direction and has an opening that opens in a lateral direction, and
the tape housing includes a tray that is rotatably or slidably arranged therein and on which the reel is placed, and a lever that rotates or slides the tray.

5. The component supply device according to claim 2 , wherein
the reel holding section has a box-shaped tape housing that is arranged in a plurality of stages in an up-down direction and has an opening that opens in a lateral direction, and
the tape housing includes a tray that is rotatably or slidably arranged therein and on which the reel is placed, and a lever that rotates or slides the tray.

6. The component supply device according to claim 1 , wherein
the first feeding path is formed to have a width of the new component supply tape and has a guide groove in which the new component supply tape is movably inserted; and
the partition is a lid member that is arranged on the guide groove having the new component supply tape therein; and wherein
the lid member is detachably provided on the first feeding path.

7. The component supply device according to claim 6 , wherein the feeding mechanism has a one-way clutch to rotationally drive the feeding mechanism such that movement speed of the new component supply tape by the feeding mechanism is slower than reception speed of the component supply device.

8. The component supply device according to claim 7 , wherein
the reel holding section has a box-shaped tape housing that is arranged in a plurality of stages in an up-down direction and has an opening that opens in a lateral direction, and
the tape housing includes a tray that is rotatably or slidably arranged therein and on which the reel is placed, and a lever that rotates or slides the tray.

9. The component supply device according to claim 6 , wherein the feeding mechanism is rotated such that movement speed of the new component supply tape is equivalent to reception speed of the component supply device.

10. The component supply device according to claim 6 , wherein
the reel holding section has a box-shaped tape housing that is arranged in a plurality of stages in an up-down direction and has an opening that opens in a lateral direction, and
the tape housing includes a tray that is rotatably or slidably arranged therein and on which the reel is placed, and a lever that rotates or slides the tray.

11. The component supply device according to claim 1 , wherein
the reel holding section has a box-shaped tape housing that is arranged in a plurality of stages in an up-down direction and has an opening that opens in a lateral direction, and
the tape housing includes a tray that is rotatably or slidably arranged therein and on which the reel is placed, and a lever that rotates or slides the tray.

12. The component supply device according to claim 1 , wherein
the first feeding path and the second feeding path extend in parallel; and
the second feeding path is not provided with any feeding gear that is engaged with the preceding component supply tape.

13. The component supply device according to claim 1 , wherein the partition is displaceable to close the partition in a state of covering the first feeding path or to open the partition as to displace the partition away from the first feeding path.

14. The component supply device according to claim 1 , wherein
