Component mounting device and component mounting method

1. A component mounting device comprising:

a board positioning part that positions a board;

a component supply part that includes a plurality of feeders which supply components to component supply positions;

a mounting head that picks up and mounts the components supplied by the feeders on the board which is positioned by the board positioning part;

a control unit that mounts the components on the board by controlling an operation of the mounting head based on a mounting program in which a procedure of mounting turns that are the operation of the mounting head from picking up the component to mounting the component on the board, and identifiers of the feeders which are supply sources of the components for the mounting turns are recorded;

a component detecting unit that is provided below the component supply position in each of the feeders, and detects whether the component is supplied to the component supply position of the feeder; and

a component camera which is provided between the board positioning part and the component supply part and which images the component which is being picked up by the mounting head,

wherein the control unit, after a mounting turn that is going to be performed from now on and the identifiers of the feeders that are the supply sources of the components for the mounting turn are read out from the mounting program, determines before picking up the component whether there is a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out, based on an output from the component detecting unit provided in the feeders corresponding to the identifiers that are read out, and

the control unit, when there is not a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out, performs the mounting turn that is read out,

and when there is a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out, suspends performing of the mounting turn that is read out on the board, and reads out and performs another mounting turn on the board to which the suspended mounting turn is to be performed, and

wherein the plurality of feeders have a structure that leads a plurality of the components which are not connected with each other to the component supply position.

2. The component mounting device according to claim 1 , wherein the control unit reads out the suspended mounting turn after another mounting turn is performed.

3. The component mounting device according to claim 1 , wherein the component detecting unit detects whether or not the component arrives at the component supply position due to a vacuum pressure which is supplied from a vacuum pressure supply.

4. A component mounting method that is performed by a component mounting device that comprises a board positioning part that positions a board, a component supply part that includes a plurality of feeders which supply components to component supply positions, a mounting head that picks up and mounts the components supplied by the feeders on the board which is positioned by the board positioning part, a component detecting unit that is provided below the component supply position in each of the feeders and detects whether the component is supplied to the component supply position of the feeder, and mounts the components on the board by controlling an operation of the mounting head based on a mounting program in which a procedure of mounting turns that are the operation of the mounting head from picking up the component to mounting the component on the board, and identifiers of the feeders which are supply sources of the components for the mounting turns are recorded, and a component camera which is provided between the board positioning part and the component supply part and which images the component which is being picked up by the mounting head, wherein the plurality of feeders have a structure that leads a plurality of the components which are provided to be not connected with each other to the component supply position, comprising the steps of:

reading out a mounting turn that is going to be performed from now on and the identifiers of the feeders that are the supply sources of the components for the mounting turn from the mounting program,

determining, when the step of reading out the mounting turn is performed, before picking up the component, whether there is a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out, based on the output from the component detecting unit provided in the feeders corresponding to the identifiers that are read out,

performing the mounting turn that is read out when there is not a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out as a result of the determining, and

suspending the performing of the mounting turn that is read out on the board, and reading out and performing another mounting turn on the board to which the suspended mounting turn is to be performed when there is a feeder which does not supply the component to the component supply position in the feeders corresponding to the identifiers that are read out as a result of the determining.

5. The component mounting method according to claim 4 , wherein the control unit reads out the suspended mounting turn after another mounting turn is performed.

6. The component mounting method according to claim 4 , wherein the component detecting unit detects whether or not the component arrives at the component supply position due to a vacuum pressure which is supplied from a vacuum pressure supply.
