Abstract

A component mounting system includes a plurality of component supply devices (tape feeders) each of which supplies components from a component supply position and a component mounter that sucks the components from the component supply position of each of the plurality of component supply devices with a plurality of nozzles (suction nozzles) to install the components onto a board. A suction position correction value for correcting a suction position shift from a regular suction position when each of the nozzles sucks the components from the component supply position is calculated. The suction position is corrected based on the suction position correction value to suck the components. A suction position shift amount from the regular suction position is calculated. A feeder evaluation value, which is a sum of the suction position correction value and the suction position shift amount, is calculated for each of the plurality of component supply devices.

First claim

What is claimed is:

1 . A component mounting system comprising:
a plurality of component supply devices each of which has a component supply position and supplies components from the component supply position; a component mounter that has a plurality of nozzles and sucks the components from the component supply position of each of the plurality of component supply devices with the plurality of nozzles to install the components onto a board; and a feeder evaluation value calculator that calculates a feeder evaluation value, which is a sum of a suction position correction value for correcting a suction position shift from a regular suction position when each of the nozzles sucks the components from the component supply position and a suction position shift amount from the regular suction position when the suction position is corrected based on the suction position correction value and the components are sucked, for each of the plurality of component supply devices.

2 . The component mounting system of claim 1 , further comprising:
a feeder evaluation determiner that determines a feeder evaluation of each of the plurality of component supply devices based on the feeder evaluation value.

3 . The component mounting system of claim 2 ,
wherein the feeder evaluation determiner determines the feeder evaluation based on at least one of a variation range of a plurality of the feeder evaluation value and an average value of a plurality of the feeder evaluation value.

4 . The component mounting system of claim 2 , further comprising:
a feeder evaluation value storage that keeps storing the feeder evaluation value during production, wherein the feeder evaluation determiner determines the feeder evaluation each time a predetermined number of the feeder evaluation values are accumulated in the feeder evaluation value storage.

5 . The component mounting system of claim 2 ,
wherein the feeder evaluation determiner includes a notifier that gives a worker a notification which suggests maintenance of a component supply device, of which the feeder evaluation falls short of a predetermined rank, out of the plurality of component supply devices.

6 . The component mounting system of claim 1 , further comprising:
a correction value calculator that calculates the suction position correction value for each combination of each of the plurality of nozzles and each of the plurality of component supply devices.

7 . The component mounting system of claim 2 ,
wherein the plurality of component supply devices each include a display, and wherein the component mounting system further comprises: a feeder rank selector that can select the feeder evaluation; and a display controller that causes the display of a component supply device corresponding to a feeder evaluation selected by the feeder rank selector, out of the plurality of component supply devices, to display that the component supply device corresponding to the selected feeder evaluation has the selected feeder evaluation.

8 . The component mounting system of claim 7 , further comprising:
a wireless communicator that performs wireless communication between the plurality of component supply devices and the feeder rank selector.

9 . The component mounting system of claim 7 ,
wherein the display controller causes the display to emit light beams having different colors according to the feeder evaluation.

10 . The component mounting system of claim 7 ,
wherein the display controller causes the display to display the feeder evaluation.

11 . The component mounting system of claim 7 ,
wherein the display controller causes the display to flicker at different timings according to the feeder evaluation.

12 . An evaluation method of a component supply device in a component mounting system including: a plurality of component supply devices each of which has a component supply position and supplies components from the component supply position; and a component mounter which has a plurality of nozzles and sucks the components from the component supply position of each of the plurality of component supply devices with the plurality of nozzles to install the components onto a board, the method comprising:
calculating a suction position correction value for correcting a suction position shift from a regular suction position when each of the nozzles sucks the components from the component supply position; sucking the components by correcting the suction position based on the suction position correction value; calculating a suction position shift amount from the regular suction position; and calculating a feeder evaluation value, which is a sum of the suction position correction value and the suction position shift amount, for each of the plurality of component supply devices.

13 . The evaluation method of a component supply device of claim 12 , further comprising:
determining a feeder evaluation of each of the plurality of component supply devices based on at least one of a variation range of a plurality of the feeder evaluation value and an average value of a plurality of the feeder evaluation value.

14 . The evaluation method of a component supply device of claim 12 , further comprising:
determining a feeder evaluation each time a predetermined number of the feeder evaluation values are accumulated.

15 . The evaluation method of a component supply device of claim 12 ,
wherein the suction position correction value is calculated for each combination of each of the plurality of nozzles and each of the plurality of component supply devices.
