Abstract

An electronic component supply apparatus that transports a component supply tape which has accommodation sections and sprocket holes formed at regular intervals and which accommodates an electronic component in each of the accommodation sections, to a component picking-up position and that supplies the electronic component accommodated in the accommodation section to a component mounting apparatus, the electronic component supply apparatus includes a slippage detector that detects slippage occurring in a transport of the component supply tape by a component supply tape transport unit; and a transport correction unit that corrects the transport of the component supply tape by the component supply tape transport unit based on the slippage detected by the slippage detector.

First claim

What is claimed is:

1 . An electronic component supply apparatus that transports a component supply tape which has a plurality of accommodation sections and sprocket holes formed at regular intervals and which accommodates an electronic component in each of the accommodation sections, to a component picking-up position and that supplies the electronic component accommodated in the accommodation section to a component mounting apparatus, the electronic component supply apparatus comprising:
a main body unit which is provided with a transport path that guides the component supply tape from an insertion port, through which the component supply tape is inserted, to a discharge port, through which the component supply tape is discharged; an inserted tape feeding unit that transports the component supply tape inserted through the insertion port toward the discharge port along the transport path; a component supply tape transport unit that transports the component supply tape transported along the transport path, toward the discharge port, and positions the accommodation section at the component picking-up position on an upstream side from the discharge port; a slippage detector that detects slippage occurring in the transport of the component supply tape by the component supply tape transport unit; and a transport correction unit that corrects the transport of the component supply tape by the component supply tape transport unit based on the slippage detected by the slippage detector.

2 . The electronic component supply apparatus according to claim 1 ,
wherein the slippage detector includes a tape detector that detects an actual feeding amount of the component supply tape, and compares a feeding amount of the component supply tape transport unit to the actual feeding amount of the component supply tape to detect the slippage.

3 . The electronic component supply apparatus according to claim 2 ,
wherein the tape detector detects shapes regularly formed on the component supply tape.

4 . The electronic component supply apparatus according to claim 3 ,
wherein the tape detector is a sprocket hole detector that optically detects at least one of the sprocket holes in the component supply tape.

5 . The electronic component supply apparatus according to claim 4 ,
wherein the slippage detector compares pitch feeding times of the component supply tape transport unit to the number of the sprocket holes detected by the sprocket hole detector to detect slippage.

6 . An electronic component supply apparatus that transports a component supply tape which has a plurality of accommodation sections and sprocket holes formed at regular intervals and which accommodates an electronic component in each of the accommodation sections, to a component picking-up position and that supplies the electronic component accommodated in the accommodation section to a component mounting apparatus, the electronic component supply apparatus comprising:
a main body unit which is provided with a transport path that guides the component supply tape from an insertion port, through which the component supply tape is inserted, to a discharge port, through which the component supply tape is discharged; an inserted tape feeding unit that transports the component supply tape inserted through the insertion port toward the discharge port along the transport path; an electronic component detecting unit that detects an electronic component accommodated in the accommodation section of the component supply tape in the transport path; a component supply tape transport unit that transports the component supply tape transported along the transport path, toward the discharge port, and positions the accommodation section at the component picking-up position on an upstream side from the discharge port; a slippage detector that detects slippage occurring in the transport of the component supply tape by the component supply tape transport unit; and a transport correction unit that corrects the transport of the component supply tape by the component supply tape transport unit based on the slippage detected by the slippage detector and transports the electronic component detected by the electronic component detecting unit to a predetermined position.

7 . The electronic component supply apparatus according to claim 6 ,
wherein the slippage detector includes a tape detector that detects an actual feeding amount of the component supply tape, compares a feeding amount of the component supply tape transport unit to the actual feeding amount of the component supply tape to detect the slippage.

8 . The electronic component supply apparatus according to claim 7 ,
wherein the tape detector is a sprocket hole detector that optically detects at least one of the sprocket holes in the component supply tape.

9 . The electronic component supply apparatus according to claim 8 ,
wherein the slippage detector compares pitch feeding times of the component supply tape transport unit to the number of the sprocket holes detected by the sprocket hole detector to detect the slippage.

10 . An electronic component supply method of transporting a component supply tape which has a plurality of accommodation sections and sprocket holes formed at regular intervals and which accommodates an electronic component in each of the accommodation sections, to a component picking-up position, and supplying the electronic component accommodated in the accommodation section to a component mounting apparatus, the electronic component supply method comprising:
transporting the component supply tape having a leading end portion inserted through an insertion port of a transport path toward a discharge port of the transport path by an inserted tape feeding unit; detecting a leading electronic component of the component supply tape in the transporting of the component supply tape; transferring the leading end portion of the component supply tape to a component supply tape transport unit disposed on a discharge port side of the transport path; detecting slippage of the component supply tape in the transferring of the leading end portion; and transporting the leading electronic component to a predetermined position by performing an additional transport operation corresponding to the detected slippage by the component supply tape transport unit.

11 . The electronic component supply method according to claim 10 ,
wherein, in the slippage detecting, a feeding amount of the component supply tape transport unit is compared to an actual feeding amount of the component supply tape to detect the slippage.

12 . The electronic component supply method according to claim 11 ,
wherein, in the slippage detecting, pitch feeding times of the component supply tape transport unit is compared to the number of the sprocket holes detected by the sprocket hole detector to detect the slippage.
