Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to operation / control / management of a printed circuit board mounting apparatus used in the field of electronic equipment manufacturing, and more particularly to network management of the mounting apparatus.

[0002]

2. Description of the Related Art A conventional example of a mounting device network in which a host computer centrally manages a plurality of mounting devices will be described with reference to FIGS.

As shown in FIG. 5, a conventional control mechanism for a mounting apparatus network is a motor 19 for driving the mounting apparatus.
The device control unit 13 for controlling the device, the operation board 18, the terminal monitor 11, and the memory 20 are used to create, edit, or edit the control data, and the device control unit 13 is operated using the control data. And a man-machine control unit 12,
The host computer 15 is connected to the man-machine control unit 12 via the external input / output unit 21.

Next, the function of the conventional example will be described.

In the conventional example, the host computer 15 has only a transmitting section, and the external input / output section 21 is an interface of a communication system such as RS232C.
The transmission from 5 to each mounting apparatus is performed by one-to-one one-way transmission by switching the transmission destination each time.

In the conventional example, such a transmission method is used. The concept of the conventional centralized management method used for the centralized management of the mounting device network is developed for the centralized management of the NC processing machine. It depends on what was done. That is, N
In the case of a C processing machine, it is possible to change lots etc. simply by switching NC data etc. from the host computer side.
This is because centralized management can be carried out without problems, and there is no need for mutual operation or mutual management between the host computer and the NC processing machine.

Further, in the conventional example, the device control unit 13 is installed in each mounting device and performs all the functions shared by itself to control its own mounting device. Installed in each mounting device, and its own device control unit 13
The control data creation function, which is a part of the shared function of the man-machine control unit 12, is performed by itself and the host computer 1.
There are cases where 5 does.

Referring to FIG. 6, the operation when the control computer creates and edits control data in the host computer will be described.

In step # 1, the operator goes to the position of the host computer 15 and uses the host computer 15 to create the basic data for control which is the basis of the control of each mounting device based on the CAD data ( Since data unique to each mounting apparatus cannot be input to the memory of the host computer 15 from the side of each mounting apparatus via the external input / output unit 21, it is necessary to individually create control data according to the specific data of each mounting apparatus. Cannot be performed, and only basic control basic data is created.), This is stored in the host computer 15, and the process proceeds to step # 2.

In step # 2, the operator transfers the control basic data from the host computer 15 to the man-machine control section 12 of each mounting apparatus.
Go to 3.

In step # 3, the operator returns to the man-machine control unit 12 of each mounting apparatus, and the operation board 1
8 and the terminal monitor 11, the basic data for control is compared with the unique data of each mounting device and the condition of the printed circuit board to be mounted, and is corrected to individual control data, and the process proceeds to step # 4.

In step # 4, the operator uses the above-mentioned individual control data to operate the device control section 13 to make a trial print of the target printed circuit board, and in step # 4
Go to 5.

In step # 5, the operator adjusts the offset value for each mounting device with the trial shot data,
Go to step # 6.

In step # 6, the operator uses the individual control data and the adjusted offset value to perform mass production mounting.

[0015]

As described above, in the conventional example, since data can be transmitted only from the host computer 15 side, data can be transmitted from the host computer 15 side to each mounting apparatus side and each mounting apparatus side can be operated. However, it is not possible to transmit data to the host computer 15 or operate the host computer 15 side from each mounting apparatus side. Therefore, there is a problem in that feedback cannot be provided from each mounting device side, and an operator of the mounting device needs to reciprocate between the mounting device and the host computer 15 when creating the basic control data.

Further, the host computer 15 creates and stores the control basic data, but in each mounting apparatus, this control basic data is modified into individual control data in accordance with the unique conditions of the mounting apparatus. Since the control basic data managed by the host computer 15 is different from the individual control data used by each mounting apparatus, the effect of collective management by the host computer 15 is reduced. There is a point.

Further, since it is necessary to correct the control basic data created by the host computer 15 in each mounting device, each mounting device requires hardware for correcting the control data, and the entire mounting device network is costly. There is a problem that it becomes high.

Regarding common data (data such as the size of the board necessary for mounting the component on the printed circuit board, the origin of the board, the mounting position, and the size of the mounted component), this common data is stored in the host computer 15 side. Only by doing so, the operator of the mounting apparatus must go to the host computer 15 side and send the common data from the host computer 15 side to the mounting apparatus when each mounting apparatus needs the common data. .. Therefore, in order to avoid this, it is necessary to provide a memory on each mounting device side and store common data in the memory, which causes a problem that the cost of the entire mounting device network increases.

In order to solve the above-mentioned problems, the present invention uses a conventional mounting apparatus network system introduced from the centralized management system of the NC processing machine as a working mode unique to the mounting apparatus (in each mounting apparatus). , The NC data needs to be adjusted according to the specific conditions of each mounting device, the condition needs to be adjusted to the board size every time the board is changed, and electronic parts are supplied. Each time,
Being changed, feedback function being effective, etc.)
It is an object of the present invention to provide a mounting device network which is improved to a system conforming to the above and enables mutual operation, mutual control and mutual management between a host computer and each mounting device.

[0020]

In order to solve the above-mentioned problems, a mounting apparatus network of the present invention includes a device control section for controlling a mounting operation of each of a plurality of mounting apparatuses,
In a mounting device network that includes a man-machine control unit that has an operation board, a terminal monitor, and a memory to operate the device control unit, and the host computer centrally manages these mounting devices, the host computer has each mounting device An auxiliary storage unit having a dedicated auxiliary memory and an auxiliary memory shared by each mounting device, and a transmission / reception unit, each mounting device having a network control unit having a transmission / reception unit, and mutual operation between the host computer and each mounting device. It is characterized by enabling mutual control and management.

Further, in the mounting apparatus network of the present invention, in order to solve the above problems, it is preferable that the auxiliary storage section and the network control section of each mounting apparatus are directly connected.

[0022]

In the mounting device network of the present invention, the mounting work is performed by the control of the man-machine control unit and the device control unit in each mounting device by the central management of the host computer.
In particular, the host computer includes an auxiliary storage unit having an auxiliary memory dedicated to each mounting device and an auxiliary memory shared by each mounting device, and a transmission / reception unit, and each mounting device includes a network control unit having a transmission / reception unit. It enables mutual operation, mutual control, and mutual management between the host computer and each real device.

Further, since the auxiliary storage section and the network control section of each mounting apparatus are directly connected, each mounting apparatus side has its own auxiliary memory and each mounting apparatus dedicated auxiliary memory even when the host computer is operating. The mounting device shared auxiliary memory can be used.

As a result, the operator operates the hardware such as the CPU and the memory of the host computer by using the operation board and the terminal monitor in the man-machine control unit of an arbitrary mounting apparatus, and the operator is peculiar to each mounting apparatus. The control data can be created or modified using the conditions, and the control data can be stored in the host computer and transferred to each mounting apparatus. Therefore, management data such as control data and common data need only be stored in each memory of the host computer, and collective management by the host computer becomes very effective, and the memory on each mounting device side is
A small capacity sufficient to store NC data and the like necessary for control at that time is sufficient.

Further, when the change of the common data is confirmed / executed by an arbitrary mounting apparatus, the common data managed by another mounting apparatus is controlled by the operation board and the terminal monitor of the arbitrary mounting apparatus. You can change and check.
