Abstract

In a component mounting device, a head held by a head holding section is automatically exchanged from one of a pickup head attached with a suction nozzle that holds and releases component, and a dispensing head with a dispensing tool that dispenses adhesive, to the other of the heads. When the pickup head is held, a nozzle camera images the suction nozzles at nozzle positions attached to the pickup head from the side using an optical system unit and acquires suction nozzle image data. When the dispensing head is held, the nozzle camera images a dispensing nozzle positioned at the center axis of the head holding body from the side using the optical system unit and acquires dispensing nozzle image data. Component related inspection is performed based on the suction nozzle image data and dispensing related inspection is performed based on the dispensing nozzle image data.

First claim

The invention claimed is:

1. A component mounting device that performs applying of a viscous fluid to a board and mounting of a held component to a board, the component mounting device comprising:
a storing device that stores multiple types of heads that include a mounting head with a component holding tool that holds and releases a component, and a dispensing head with a dispensing tool that dispenses the viscous fluid from a dispensing outlet;
a head holding device that exchangeably holds the heads;
a head moving device that moves the head holding device;
a head exchange control device that exchanges one of the mounting head and the dispensing head being held on the head holding device for the other of the mounting head and the dispensing head by controlling the head moving device and exchanging the head being held on the head holding device for the head stored in the storing device;
an imaging device that, in a case in which the head holding device is holding the mounting head, images the component holding tool of the mounting head from the side and acquires component holding tool image data, and in a case in which the head holding device is holding the dispensing head, images the dispensing tool of the dispensing head from the side and acquires dispensing tool image data; and
an inspection device that performs component related inspection of at least one of the component holding tool and the component held by the component holding tool based on the component holding tool image data, and that performs dispensing related inspection of at least one of the dispensing tool and the viscous fluid dispensed from the dispensing outlet of the dispensing tool based on the dispensing tool image data.

2. The component mounting device according to claim 1 ,
wherein the inspection device performs the dispensing related inspection that includes at least one of application good/bad inspection that judges whether application is good/bad by detecting viscous fluid on the dispensing outlet based on the dispensing tool image data imaged after viscous fluid has been applied on the board from the dispensing tool, dripping inspection that judges whether viscous fluid is dripping from the dispensing outlet based on the dispensing tool image data image when viscous fluid is not being applied to the board, and dispensing tool inspection that judges whether the type of dispensing tool used by the dispensing head is correct based on the dispensing tool image data.

3. The component mounting device according to claim 1 ,
wherein the component holding tool is detachable from the mounting head,
the imaging device includes a first optical system that is adjusted such that, when the dispensing head is held by the head holding device, the dispensing tool of the held dispensing head is in focus, and, when the mounting head is held by the head holding device, the component holding tool attached to the held mounting head is in the field of view, and
the inspection device performs the dispensing related inspection based on the dispensing tool image data imaged by the imaging device using the first optical system, and performs component related inspection that includes mounting inspection which inspects whether the component holding tool is attached to the mounting head based on the component holding tool image data imaged by the imaging device using the first optical system.

4. The component mounting device according to claim 1 ,
wherein the imaging device includes a first optical system adjusted such that, when the dispensing head is held by the head holding device, the dispensing tool of the held dispensing head is in focus, and a second optical system adjusted such that, when the mounting head is held by the head holding device, the component mounting tool of the held mounting head is in focus, and
the inspection device performs the dispensing related inspection based on the dispensing tool image data imaged by the imaging device using the first optical system, and performs component related inspection based on the component holding tool image data imaged by the imaging device using the second optical system.

5. The component mounting device according to claim 1 ,
wherein multiple holding tools are attachable/detachable to/from the mounting head,
the imaging device includes a first optical system that is adjusted such that, when the dispensing head is held by the head holding device, the dispensing tool of the held dispensing head is in focus, and, when the mounting head is held by the head holding device, the component holding tool attached to a first position of the held mounting head is in the field of view, and a second optical system adjusted such that, when the mounting head is held by the head holding device, the component mounting tool positioned at a second position different to the first position of the held mounting head, is in focus, and
the inspection device performs the dispensing related inspection based on the dispensing tool image data imaged by the imaging device using the first optical system, performs the component related inspection including attachment inspection that inspects whether the component holding tool is attached to the first position based on the component holding tool image data image by the imaging device using the first optical system, and performs inspection related to a component held by the component holding tool positioned at the second position based on the component holding tool image data imaged by the imaging device using the second optical system.

6. The component mounting device according to claim 1 ,
wherein the imaging device is provided as one unit with the head holding device.
