Abstract

A component mounting system that efficiently determines a component as a bulk component to be mounted on a bulk feeder through a simulation, and a bulk component determining method. The component mounting system includes a printed-circuit-board conveyance section that includes conveyance lanes and which convey a plurality of different types of printed circuit boards, a component supply section, a mounting head, a bulk feeder, and a bulk component determining section that performs a simulation in which operation times when the components supplied from the component supply section are moved on the printed circuit boards on the conveyance lanes are calculated for all the components and determines the bulk component to be mounted on the bulk feeder based on the calculated operation times.

First claim

The invention claimed is:

1. A component mounting system, comprising:
conveyance lanes that convey a plurality of different types of printed circuit boards;
at least one tape feeder that supplies components to be mounted on the plurality of printed circuit boards;
a mounting head that includes a plurality of suction nozzles which suck the components supplied from the at least one tape feeder and bulk components supplied by a bulk feeder that is integrally held by the mounting head, and the mounting head mounts the components and the bulk components sucked by the suction nozzles on the printed circuit boards; and
circuitry configured to perform a simulation in which operation times when the components supplied from the at least one tape feeder are moved on the plurality of printed circuit boards on the conveyance lanes are calculated for all of the components to be mounted on the plurality of different types of printed circuit boards, and determine which of all of the components is a bulk component to be mounted based on the calculated operation times for all of the components, wherein
one of the components sucked by one of the plurality of suction nozzles is allocated to a first rotation stop position of the plurality of suction nozzles by a rotary head and is captured by a component imaging device while one of the bulk components sucked by another one of the plurality of suction nozzles is allocated to a second rotation stop position of the plurality of suction nozzles by the rotary head.

2. The component mounting system according to claim 1 ,
wherein the conveyance lanes include two conveyance lanes that are arranged in parallel, each of the two conveyance lanes conveying a different type of the plurality of printed circuit boards, and the components supplied from the at least one tape feeder are mounted on the respective printed circuit boards conveyed by the two conveyance lanes.

3. The component mounting system according to claim 2 ,
wherein the circuitry is further configured to calculate operation times when the components supplied from the at least one tape feeder are transferred to the plurality of printed circuit boards on the two conveyance lanes, and select another one of the components of which the operation time is relatively long as a bulk component, among the operation times calculated for all the components on the plurality of different types of printed circuit boards.

4. The component mounting system according to claim 1 ,
wherein the at least one tape feeder includes a plurality of tape feeders, each of the plurality of tape feeders including a supply position at an end of each respective tape feeder, and
wherein the bulk feeder includes a case that stores the bulk components and includes a guide passage that supplies the bulk components from the case to a supply position that corresponds with the second stop position of the plurality of suction nozzles on the mounting head.

5. The component mounting system according to claim 4 ,
wherein the circuitry is further configured to perform the simulation in which operation times when the components supplied from the supply position at the end of each respective tape feeder are calculated.

6. The component mounting system according to claim 1 , wherein the one of the components sucked by the one of the plurality of suction nozzles is allocated to the first rotation stop position of the plurality of suction nozzles by the rotary head and is captured by the component imaging device while the one of the bulk components sucked by the another one of the plurality of suction nozzles is allocated to the second rotation stop position of the plurality of suction nozzles by the rotary head and another one of the components positioned in a third rotation stop position of the plurality of suction nozzles is mounted on one of the plurality of printed circuit boards by the mounting head.
