Component mounting apparatus with feeder control device
A component mounting apparatus including a component supply device which includes a carrier tape that accommodates a component to be mounted on a board in which a plurality of feeders having carrier tapes loaded are respectively mounted at a plurality of mounting positions, which automatically discharges a carrier tape to a tape insertion port of the feeder based on a component discharge instruction, and which automatically conveys an inserted carrier tape to a suction position at which a component is suctioned when the carrier tape is inserted into the tape insertion port; and control device which instructs discharge or supply of a component.
1. A component mounting apparatus, comprising:
a component supply device including feeder and a reel detachably attached to the feeder, the reel configured to hold a carrier tape, the feeder configured to convey in a feeding direction the carrier tape that accommodates a component to be mounted on a first board which is a first board type of multiple board types, the feeder including a feeder main body, a sprocket configured to engage with the carrier tape, a tape driving device to rotate the sprocket to drive the carrier tape engaged with the sprocket, a tape insertion port at a rear end of the feeder main body where the carrier tape from the reel enters the feeder, and a control section configured to control the driving device; and
a control device configured to
store component data including information of component types mounted in production of each of the multiple board types and information indicating a relationship between the component types and the feeder,
determine that a second board is to be produced, the second board is a second board type of the multiple board types that different from the first board type,
determine differences between the component types mounted on the first board type and those mounted on the second board type,
determine whether the component accommodated by the carrier tape is to be mounted on the second board, and
instruct the control section to discharge the carrier tape when determined that the component accommodated by the carrier tape is not to be mounted on the second board based on the component data,
wherein when the control section is instructed to discharge the carrier tape, the control section controls the tape driving device to convey the carrier tape in a direction reverse to the feeding direction to make an end of the carrier tape reversely pass through the sprocket from a suction position at which the component is suctioned by a mounter to the tape insertion port.
2. The component mounting apparatus according to claim 1 , wherein
the sprocket is upstream of the tape insertion port in the feeding direction of the carrier tape.
3. The component mounting apparatus according to claim 1 , wherein
the sprocket is a first sprocket in the feeding direction of the carrier tape of a plurality of sprockets included with the feeder.
4. The component mounting apparatus according to claim 3 , wherein
the plurality of sprockets includes a second sprocket and the suction position at which the component is suctioned is downstream of the second sprocket.
5. The component mounting apparatus according to claim 1 , wherein
the feeder includes a tape conveyance rail on which the carrier tape is conveyed from the insertion port at an upstream end of the tape conveyance rail to the suction position at a downstream end of the tape conveyance rail.
6. The component mounting apparatus according to claim 5 , wherein
the feeder includes a tape detection sensor that detects a presence of the carrier tape on the tape conveyance rail, the tape detection sensor include a dog configured to abut against an upper face of the tape conveyance rail.
7. The component mounting apparatus according to claim 6 , wherein
when the carrier tape is inserted into the tape conveyance rail the dog is pushed up by the carrier tape and the tape detection sensor detects the carrier tape.
8. The component mounting apparatus according to claim 6 , wherein
when the end of the carrier tape reversely passes through the sprocket, the tape detection sensor determines that the carrier tape does not exist on the tape conveyance rail.
