Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is directed to an automatic work system suitable for mounting work of printed board components.

[Prior Art] As shown in Japanese Patent Application Laid-Open No. 57-109007, a conventional example of this kind is to correct control data of an automatic device in real time when there is an error in the control data. In addition, as shown in Japanese Patent Application Laid-open No. 19969/1983, a library for defining round parts of printed boards was created and CA
D There is a method to improve the efficiency of design. Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 128365/1983, there is a method for collectively managing component data to improve CAD efficiency.

[FF81 to be Solved by the Invention Generally, an NC program for automatic work is created on a host computer and transmitted online or offline to the stage 4a (automatic work device) that uses it. However, on the equipment side, due to dimensional and rotational angle errors specific to the equipment, errors specific to the target object (printed circuit board), and other reasons, the raw NC program created by the host computer cannot be used as is.

Therefore, before using the created NC program,
The equipment is used on a trial basis and minor modifications are made to ensure there are no practical problems.

Although the above conventional example describes modifying the NC program, it is unclear whether the stored program has been modified or not, which is extremely inconvenient in terms of program management.

In other words, if you accidentally use an unmodified program, the yield of automatic work will be extremely poor or you will have to redo the work, so if you are unsure whether the program has been modified or not, you need to check the program again. . This recheck greatly reduces the efficiency of setup when starting work.

Further, in the past, when an attempt was made to produce the same board after a while after the NC program for a board had been modified and used, the modified NC program may have been erased from memory. This is because there is no storage means with sufficient capacity. In such a case, the same correction must be made again on the equipment side, which is inefficient.

The present invention aims to provide an automatic work system in which it is easy to understand NC programs that can actually be used, and further aims to improve the efficiency of program reuse.

[Means for Solving the Problems] In order to achieve the above objects, the present invention provides a program creation device that creates an NC program, a storage device that stores the NC program, an automatic work device that automatically performs work according to the NC program, and the above. N between each device
The automatic work device includes a transmission path for transmitting the C program, and a modification means for modifying the received NC program to match the actual work, and a communication control section for sending the modified NC program to the transmission path. However, the storage device is configured to have a communication control unit that receives the NC program from the automatic work device, and storage means that stores the received NC program separately as a modified NC program.

Furthermore, the modified NC program is configured such that a modified code is attached to the modified program at the time of modification, and the modified NC program is stored in the storage means together with the modified code.

[Operation NC program creation] An NC program for direct automatic work is created, and the storage device receives the created program via a transmission path and temporarily stores it. The automatic work device receives the program stored in the storage device via the transmission line, uses this program on a trial basis, and corrects any defects found in performing the automatic work so as not to cause any problems. The modified program is then returned to the storage device via the transmission path.

The storage circuit distinguishes and stores the returned program as a modified program.

[Example] FIG. 1 is a block diagram of an embodiment of the present invention.

Reference numeral 34 denotes a control means for controlling the operation of each of the above-mentioned parts.

The above-mentioned correction means 31 actually performs the mounting work using the NC program received from the outside, and corrects problems in mounting, such as parts not being mounted at the predetermined positions on the printed board, and dimensional problems with the printed board itself. Modify the NC program to eliminate inconveniences such as deviations. Specifically, this modification is to modify numerical values representing distances, dimensions, positions, etc. in the NC data that constitutes the NC bugogram.
It does not change the C program structure itself.

Reference numeral 4 denotes a transmission line connecting the communication control sections of each of the above-mentioned devices, and transmits the NC program between each device.

Specifically, it has a LAN (local area network) configuration.

FIG. 2 is an explanatory diagram showing the flow of the NC program in the embodiment of the present invention. 1 to 3 indicate the same parts as the device explained in FIG.

Let us say that the program created by device 1 is NC program A. This NC program A is stored in the storage means 111 in the device I.
The information is transmitted to the device 2 via the transmission path 4, and is stored at a predetermined location in the storage device 21 of the device 2 by the read/write device 22.

Thereafter, in response to a request from device 3, NC program A stored in device 1 or device 2 is read out, and the
3 and temporarily stored in storage means 313.

In the apparatus 3, the automatic machine 33 is operated by actually using the NC program A to mount components on a printed board in the form of insertion and surface mounting. During these mounting operations, if there is a difference in the dimensions of the actual printed board, or if the dimensions of the parts are slightly different, etc., it is necessary to correct the mounting position of the printed board and the position where the manipulator grips the part. When making the above correction, the correction means 31 of the device 3 uses numerical data representing the position of the printed board mounting holder in the NC program A and numerical data representing the gripping position of the component manipulator. In addition, when making the above corrections, the corrected NC program B' is marked with a code indicating that it has been corrected, such as ◎ 5.As mentioned above, the NC program includes NC data and setup data, as shown in FIG. Modification signs are given in these units.

The program modified in this way is temporarily stored as NC program B in the storage means 313 of the device 3.

Then, the NC program B of the corrected modified code pair is stored in the storage means 21 of the device 2 from the device 3 via the transmission line 4. In this case, the modified code pair NC10-gram B is stored in the storage means 2 in an updated manner at the location of the original program A, or stored in a different location. In this way, the NC programs modified for each of the plurality of automatic work devices are collectively stored and saved in the device 2. In this state, by operating the storage device 2 alone, all the programs in the storage means 21 can be viewed, and it can be seen whether or not the NC program can be used immediately. In other words, the program with the modification code can be used immediately. Therefore, preparations for automatic work can be carried out efficiently while checking available programs.

Thereafter, when there is a request from the automatic work equipment 3 side, the NC program B of the requested correction code pair is retrieved and read out by the retrieval means 23, and sent to the equipment 3 via the transmission line 4.
