[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
[0011]
1 (a), (b), and (c) all show the packaging of an electronic component to which an ID is attached, and the packaging of the electronic component includes a reel-type packaging 1 and a stick-type packaging. There are a form 2 and a tray-type packing form 3. The electronic component 4 has a high-density, ultra-small label ID 5 attached thereto using a two-dimensional bar code or the like. In the ID 5, information such as a part model and a production lot number is displayed or stored as part information.
[0012]
The electronic components in the form of 1, 2, and 3 are set in the component supply unit 7 of the component mounting machine 6 shown in FIG. As for the setting method, taking the form of the reel-type package 1 as an example, as shown in FIG. 3, first, the electronic components of the reel-type package 1 are set in the component magazine 8, and this magazine 8 is supplied to the component supply unit 7 Attach to. At this time, the ID reading sensor 9 attached to each channel of the component supply unit 7 automatically reads the ID 5 attached to the electronic component 4 on the reel type package 1 set in the magazine 8, and By transmitting the information to the component mounting machine control computer 10, it is possible to recognize which component has been set in which channel.
[0013]
FIG. 4 is a diagram for explaining the current state of the creation of the component mounting machine embedded data, and FIG. 5 is an explanatory diagram of the component mounting machine embedded data creation according to the present embodiment.
[0014]
The data for mounting on the component mounting machine is created from the CAD information consisting of the mounting data of the printed circuit board, the shape data of the component to be mounted, and the component data applicable to each mounting machine (reel type, stick type, tray type each form of packing). The CAM information (component mounting machine data described later) is generated by the host computer and sent to the component mounting machine. The component mounting machine reads the component mounting machine data, takes out the corresponding electronic component, moves the table to the mounting position of the printed circuit board, and mounts the component.
[0015]
Conventionally, the component channel information is fixed information as shown in FIG. 4, so that the CAM creation on the upper level and the component channel position on the component mounting machine side must completely match. For this reason, the operator has to set a part of the corresponding type in the designated channel while looking at the list of set parts for each channel created by the host computer, and this work requires a great deal of time.
[0016]
On the other hand, as shown in FIG. 5, by reading the component information by the ID reading sensor 9 attached to each channel of the component supply unit of the component mounting machine, the type component in the read information is set to which channel. You can tell if it's warm. Based on this information, when the type component to be set in the component channel already created in the host computer changes, the fixed channel No. of the component mounting machine data is changed to the channel No. in which the corresponding type component is set. By doing so, the operator can complete the work only by setting the used parts to an arbitrary channel without looking at the list of set parts for each channel, and the component mounting machine reads the changed component mounting machine data, and The electronic component to be removed is taken out, the table is moved to the mounting position of the printed circuit board, and the component is mounted. That is, the operator can omit the work of inspecting the mounted components in the next process after setting the used component to an arbitrary channel, and the production efficiency of the printed circuit board is improved remarkably as compared with the related art.
[0017]
As for the traceability of the lot number and the like of the electronic component mounted on the printed circuit board, as shown in the example of the trace data file format in FIG. By adding component information such as component type and component lot number read by the sensor 9 to the component mounting machine data and storing them in a dedicated file for each printed circuit board, it is possible to trace all information on the used electronic components. Thus, the parts can be managed collectively.
[0018]

The format of the component mounting machine data generally includes a mounting order No. 11, an X coordinate 12 and a Y coordinate 13 indicating a mounting position, a component mounting angle 14, and a component supply channel No. 15, and as shown in FIG. By replacing the component supply channel No. 15 fixed in the information with the mounting machine data to the channel No. where the components are actually set, it is possible to supply components to any channel without relying on the set component list by channel. It becomes. In the example of FIG. 7, the parts CH3 and CH4 among the parts already fixed by the host computer are changed to CH1 and CH3 for each channel read by the sensor. The channel number of the data is automatically changed from 003 to 001, and the channel number of the data in the mounting order 002 is automatically changed from 004 to 003.
