Description

[Detailed Description of the Invention] ΓTechnical Field of the Invention This invention relates to a DIP type controller used in information processing devices and various control devices using microprocessors.
This relates to a device and method for writing programs into ROM (dual inline package read-only memory), and aims to provide an automatic writing device and method that continuously writes predetermined programs into a large number of ROMs. It is.

Background of Γ technology, conventional technology, and problems ROM includes mask ROM, fuse ROM, and EP-
There are ROMs, etc., but fuse ROMs and EP-ROMs require a predetermined program to be written by a ROM writer before use. Programs are written to this ROM using a ROM writer, but conventional methods include inserting and removing the ROM into the ROM writer's socket and pasting a program display label on the written ROM. Since everything was done manually, writing programs to a large number of ROMs was difficult and productivity was low.

ΓPurpose of the invention This invention was made for the purpose of reducing the work load in the process of writing programs to fuse ROM and EP-ROM.
The object of the present invention is to provide a fully automated ROM writing device and method that sequentially writes a predetermined program to a ROM.

Configuration of the ΓInvention To explain using the reference numerals of the illustrated embodiment, the automatic ROM writing device of the present invention writes the ROM 16 in the magazine 6 loaded on the magazine table 5 to the chute 2.
The magazine feeder 4 drops the ROMs one by one along the chute 5 into the ROM supply station 8, and the ROMs 16 conveyed to the ROM ejection station 14 are connected to this and fall into the loaded magazine 15 along the chute 40. A stack device 13, a label printing device 9, a printed label supply station 12, a ROM writer 1 having a plurality of two-dimensionally arranged sockets 2, and a transport device for moving and positioning a handling head 18 on a two-dimensional plane. The handling head 18 of the conveyance device has a vacuum nozzle 60 for sucking and holding the ROM 16 and the label 35, a sensor 62 provided near the vacuum nozzle, and a socket lock lever lifting mechanism 85. It is characterized by:

Moreover, the ROM writing method of this invention is based on the magazine 6
The ROM 16 stored in the
The ROM is supplied to the ROM supply station 8 by the handling head 18 which is supplied to the supply station 8 and is equipped with a vacuum nozzle 60.
16 are sequentially conveyed and pushed into a plurality of two-dimensionally arranged sockets 2 of the ROM writer 1, and the lock lever 17 of the socket 2 is locked at the time of the pushing, and the ROM writer 1 is pushed in as described above.
While writing a program in the ROM 16, labels 35 corresponding to the program are printed and sequentially supplied to the label supply station 12, and the supplied printed labels 35 are held by suction with the handling head 18. socket 2
The second step is to sequentially attach the ROMs to the upper ROM 16, and after the program has been written, the handling head 18 releases the lock lever 17 of the socket 2 and holds the ROM 16 by suction.
This is characterized by repeating a series of steps including a third step of sequentially transporting the ROM to the ejection station 14 and storing it in the magazine 15 loaded in the ejection station.

...Description of the operation of the entire apparatus Next, the operation of the entire apparatus consisting of each component configured as described above will be explained.

A magazine 6 containing a ROM 16 is loaded on the magazine table 5, and an empty magazine 15 is loaded on the stack device 13. ROM1 in magazine 6
The ROMs 6 are fed one by one to the ROM supply station 8 by the magazine feeder 4, and the ROMs 16 are sucked by the vacuum nozzle 60 of the handling head 18 and transported and positioned onto the socket 2 of the ROM writer 1. The main finger 58 then extends to insert the ROM 16 into the socket 2, and then the auxiliary finger 70 extends to insert the ROM 16 into the lock lever 1.
7 is laid down and the ROM 16 is locked, the main finger 58 and the auxiliary finger 70 are retracted.
By the above operation, ROM1 is installed in all sockets 2.
6 is inserted, ROM writer 1 connects to socket 3.
The program in the master ROM inserted into the master ROM 16 is transferred to each loaded ROM 16. This transcription requires approximately 3 to 5 minutes. this
While the ROM writer 1 is transcribing the program, the label printing device 9 prints the labels 35 and sequentially sends the printed labels 35 to the label supply station 12. The sent-out label is adsorbed and held by the vacuum nozzle 60 of the handling head 18, is conveyed to the ROM 16 on each socket 2, and is transferred to the ROM 16 by the downward movement of the main finger 58.
pasted on top. In the illustrated embodiment, after the label is pasted, the vacuum nozzle 60 of the handling head 18 holds the presser plate 91 (FIG. 1) by suction and presses the presser plate 91 against the upper surface of the label to which the label 35 is attached. It is ensured that it is attached to ROM16. The holding plate 91 is a metal plate with a felt or rubber plate attached to its lower surface.
When not in use, it is fixed at a predetermined position on the ROM writer 1 by a magnet. After pasting the label 35 and writing the program, the handling head 18 is positioned in the socket 2 with the auxiliary finger 70 extended, and the main finger 58
extends and holds the ROM 16 on the socket, and then the auxiliary finger 70 retracts to raise the lock lever 17, and the written ROM 16 is attracted to the vacuum nozzle 60 and pulled out from the socket 2.
The ROM is transported to the ROM ejection station 14 and dropped. fell into discharge station 14
The ROM 16 slides down the chute 40 and is stored in the magazine 15 one after another. The number of ROMs 16 that have fallen into the magazine 15 is the number of ROMs 16 that have fallen into the magazine 15.
When one magazine becomes full, the ejection position of the written ROM 16 is switched to the next ejection station 14. Full magazine 15
is removed from the stack device 13, the empty magazine 6 is removed from the magazine table 5 and installed in the stack device 13, and a new ROM is inserted into the stack device 13.
It is loaded into the magazine 6 or magazine table 5 that houses the. By repeating the above operations, programs are automatically written to a large number of ROMs 16.

Effects of the ΓInvention As described above, the ROM writing device and method of the present invention can supply ROM to a ROM writer having a large number of writing sockets, attach a label to a written ROM, and write a ROM from the ROM writer. Since all the discharges are done automatically,
It is possible to completely automate the process of writing a program into the ROM, thereby saving labor and improving productivity in this process. Also, it is possible to send ROM to the ROM supply station and store ROM from the ROM ejection station into the magazine.
Since this is done by shooting using the weight of the ROM, the structure of the device is simple and its operation is reliable. In addition, the ROM is supplied directly from the magazine, and the written ROM is stored directly into the magazine from the ejection station, making it easier to handle the ROM before and after the ROM writing process, and preventing damage to the ROM. There is no possibility of it happening. Furthermore, a vacuum nozzle is provided on the handling head so that the ROM and the label can be transported by the same head, and a lock lever tilting mechanism is provided on the handling head to raise and lower the lock lever of the socket when inserting or removing the ROM. Therefore, the structure of the handling head is simplified, and the control of the conveying device is also simplified.
