Component mounting system

1. A component mounting system comprising:

(a) mounting machines arranged along a direction of conveying a circuit board;

(b) a feeder mount base in each of the mounting machines;

(c) a feeder removably mounted on the feeder mount base of each of the mounting machines;

(d) a mounting head in each of the mounting machines, the mounting head sucking a component supplied from the feeder for mounting on the circuit board;

(e) a moving mechanism in each of the mounting machines, the moving mechanism configured to removably mount and move the mounting head;

(f) an inspection camera unit mounted, replaceably with the mounting head, on the moving mechanism of any one of the mounting machines, the inspection camera unit configured to image an inspection target part of the circuit board; and

(g) an inspection image processing unit mounted, replaceably with the feeder, on the feeder mount base where the inspection camera unit is mounted, the inspection image processing unit processing an image signal output from the inspection camera unit to inspect the inspection target part.

2. The component mounting system according to claim 1 , wherein

one of the mounting machines on an upstream side mounts on the circuit board an electronic component required to be shielded, and another one of the mounting machines on a downstream side mounts a shielding case on the circuit board so as to cover the electronic component, and

still another one of the mounting machines having the inspection camera unit and the inspection image processing unit mounted on the still another one of the mounting machines is between the one of the mounting machines that mounts the electronic component required to be shielded and the another one of the mounting machines that mounts the shielding case.

3. The component mounting system according to claim 1 , wherein

any one of the mounting machines mounts a BGA-type component, and

the mounting machine having the inspection camera unit and the inspection image processing unit mounted on the mounting machine is on a side upstream from the any one of the mounting machines that mounts the BGA-type component.

4. The component mounting system according to claim 1 , wherein

the inspection image processing unit includes a display unit that displays inspection information and an inspection setting function of setting an inspection method by an operator.

5. The component mounting system according to claim 1 , wherein

the inspection camera unit includes an illumination device that illuminates the inspection target part.

6. The component mounting system according to claim 5 , wherein

the illumination device includes illumination light sources of a plurality of types, and is configured to allow an illumination pattern to be selected from among a plurality of illumination patterns obtained by combining the illumination light sources.

7. The component mounting system according to claim 1 , wherein

the inspection image processing unit includes learning means that learns conforming-item data obtained through an inspection and inspecting means that inspects the inspection target part by comparing a result of image processing of the inspection target part of the with the conforming-item data learned by the learning means.

8. The component mounting system according to claim 1 , wherein

a conveyor that discharges a circuit board determined by the inspection image processing unit as defective is removably mounted on the feeder mount base of the mounting machine having the inspection camera unit and the inspection image processing unit mounted on the mounting machine or one of the mounting machines that comes immediately after the mounting machine having the inspection camera unit and the inspection image processing unit.
