Can be coupled to the component mounting apparatus 20 by the same coupling mechanism as described above.

The clamp mechanism 11 may employ any mechanism as long as it can be clamped with one touch, and is not limited to the above-described toggle mechanism. For example, it is also possible to adopt a structure in which a hook is connected to a piston rod of a pneumatic or hydraulic cylinder and the hook is hooked on the hook pin 28 by a pull-in operation.

FIG. 5 (a) is an explanatory view from above of a component supply position of a tray type component supply device and a component supply cassette with respect to a conventional component mounting device, and FIG. 5 (b) is a component view of the present invention. It is the figure which looked at the component supply position by the plurality of loading tables of the tray type component supply device and the cassette type component supply device with respect to the mounting device from above.

As shown in FIG. 2A, conventionally, the component supply position 39 of the component supply cassette mounted on the component supply table 38 of the component mounting device 37 is located at a position slightly distant from the component recognition camera device 40. In contrast, the component supply position 42 by the supply stage 41 of the tray-type component supply device is
It is formed at a position very close to the component recognition camera device 40. FIG. 7A shows a distance L from an arbitrary point a in the component supply position 39 of the component supply cassette to the imaging lens of the component recognition camera device 40 at this time for reference. A work head (not shown) of the component mounting device 37 includes:

Can be set in the same range as the component supply position by the supply stage 3 of the tray-type component supply device 1. Thereby, the component supply position of the cassette type component supply device by the plurality of loading tables 30 can be brought close to the component recognition camera device 44 in the same manner as the component supply position by the tray type component supply device 1.

This is, as shown in FIG. 4, the mounting base 3 of the plurality of loading tables 30 of the cassette type component supply device.
4 can be arranged to protrude more inside the component mounting apparatus 20. Thus, when the position of the point a of the component supply position 43 is set to an arbitrary component suction position in the same manner as described above, the distance from the position of the point a to the component recognition camera device 44 is smaller than that in the case of FIG. It is reduced to the distance L1. Thus, the moving amount of the working head for the image recognition of the component is reduced. The work efficiency of component mounting is improved.

The operation of the work head for picking up components on the component mounting device slightly differs depending on whether the component supply device is a tray type or a cassette type. Each of the above-described tray-type component supply device 1 and the plurality of loading tables 30 of the cassette-type component supply device has four parts, that is, a front left half, a front right half, a rear left half, or a rear right half. One of the mounting positions of
Can be installed at more than one location.

Conventionally, only the operator inputs a key to notify the information of the model and the mounting position of the component supply device to the component mounting device. However, in the present invention, as shown in FIG. 3 or FIG. When the component supply device is connected to the component mounting device, the component mounting device automatically determines the model and mounting position of the component supply device that is automatically connected. Hereinafter, this will be described.

As shown in the drawing, the data configuration (component mounting device information) 53 of the memory 47 includes information of the component supply device, for example, type data of the component supply device, control data from area 0 to area 3 of the storage area of the memory 47. Adjust data, production-related information, and maintenance information are stored. Also,
The memory 47 further secures a plurality of areas (areas 4 to 7 in the example in the figure) as data spare areas.

FIG. 8 is a flow chart showing the control operation between the component supplying device 45 and the component mounting device 20. In the figure, first, when the start of processing is instructed by inputting a start key from an operation panel or the like (not shown) (S
1), the power supply of the component supply device 45 is turned on (S2),
Further, the power of the component mounting apparatus 20 is turned on (S3).

Subsequently, it is determined whether or not the component supply device 45 and the component mounting device 20 are electrically connected (S
4) If it is not connected (S4 is no), processing of "no connection" such as blinking a warning light or displaying a warning on a display device is performed, but if it is connected (S4 is yes)
s), the memory information (the component mounting device information 53 shown in FIG. 7) stored in the memory 47 is transferred (S6).
In this process, the component mounting device information 53 of the memory 47 is transmitted to the control unit 51 of the component mounting device 20 based on an information transfer command from the control unit 51 of the component mounting device 20.

The component mounting device 20 temporarily stores the component supply device information 53 in a storage device (not shown) (S7). Then, when the component mounting work is performed, it is reflected on the control of the component supply process of the expression component supply device 45 (S
8).

When the contents of the expression component supply device information are changed, rewriting is performed by writing data from the control unit 51 of the component mounting device 20 to the memory 47 of the expression component supply device 45 via the serial communication line 50. Do.

Generally, the above information of the tray-type component supply device is held as data on the component mounting device 20 side. However, as in the first embodiment of the present invention, the tray-type component supply device 1 can be connected to any of the four mounting positions of the component mounting device 20, or a plurality of component supply cassettes are collectively installed. In the case of a plurality of loading tables 30 of a cassette type component supply device to be mounted, a data input operation is required every time the component supply device 45 is connected to the component mounting device 20.

The component mounting device information 53 is stored in the memory 47 of the component supply device 45 in advance as described above,
If this information is read on the component mounting device 20 side,
For example, even when the component supply device 45 is connected to a plurality of component mounting devices 20 by exchanging them, there is no need to input special information only by a mechanical connection operation, and the connection operation is further facilitated.

[0039]

As described above in detail, according to the present invention, a component mounting device fixed to a production line is provided with a stop positioning pin, a guide hole, and a latching pin, and a movable component supply device. The device is equipped with a stop groove, conical projection and clamp mechanism, and both devices are connected and fixed by simple positioning operation and simple fixing operation, making it possible to attach and remove the component supply device to the component mounting device with one touch. This makes it possible to easily and quickly set up the replacement of the component supply device with the component mounting device, which is changed according to the model change of the circuit board, thereby improving the efficiency of component mounting.

Further, a cassette type component supply device on which a plurality of component supply cassettes are mounted is configured to be movable similarly to the tray type component supply device, and the respective component supply stages are arranged at the same position of the component mounting device. So,
The movement amount of the work head for component recognition by the component recognition camera is shorter than before, thereby improving the work efficiency of component mounting.
