Description

[Detailed Description of the Invention] [Summary] The present invention utilizes a storage file of component insertion data for automatic component insertion and a storage file of component insertion schedule data to perform taping processing on the inserted component. In response to inputting a number of a magazine that accommodates a component insertion printed board, first data editing is performed to rearrange the identification information string of the printed board read from the component insertion schedule data storage file in the opposite order to the automatic insertion order. After ivy,
A second data edit is performed in which the insertion part identification information string read from the component insertion data storage file is rearranged in the reverse order of the automatic insertion order according to the printed board identification information string in the reverse order, and the inserted parts in the reverse order are rearranged. This system is characterized in that the parts are taped using a sequencer based on the identification information string, making it possible to improve the efficiency of taping work and centralize data management.

[Industrial application field]

The present invention relates to a taping device for automatically inserting parts that is effective when applied to a system for automatically inserting parts into printed boards of various types and in small quantities.

In recent years, there has been a trend toward automation in mounting components onto printed circuit boards using automatic component insertion machines such as IC inserters, radial inserters, and axial inserters.

When inserting components using an axial inserter, axial lead components are taped in an automatic insertion order, and a machine called a sequencer is used for the taping process. That is, the sequencer cuts off various taped axial lead parts with a unit cutter, receives and transports them on a conveyor, and tapes them onto a roll-type long adhesive tape in the reverse order of automatic insertion. Therefore,
As shown in FIG. 6, on the long adhesive tape 102 wound on the take-up reel 101, the insertion parts 103 are arranged in automatic insertion order at intervals of 5 mm from the winding end to the winding start end. In addition, when changing the printed circuit board into which a component is inserted, a space SP corresponding to one component is provided in the component taping arrangement to facilitate identification.

[Conventional technology]

Conventionally, the following data processing has been performed in order to cause the sequencer to perform the taping process as described above. In other words, while referring to the circuit wiring diagram of the printed board and the parts insertion schedule table such as the supply order of printed boards from the storage magazine, arrange the parts in the opposite order to the automatic insertion order of the taping data of the parts, and punch the paper tape with a teletype. Data creation processing and data input processing of setting the paper tape on a sequencer and inputting taping data were performed.

[Problem that the invention seeks to solve]

The conventional taping processing method for inserted components described above does not pose a problem in so-called high-volume production of small numbers of products, in which a large number of printed circuit boards with the same wiring pattern (component insertion format) are processed, but it is possible to process printed boards with different wiring patterns in small quantities. In so-called high-mix, low-volume production, a large amount of data such as the figure number and overall version number (identification information) of the printed board to be inserted is created on paper tape each time the product is changed, and paper tape data is set in a sequencer. Rework must be carried out frequently. Furthermore, the taping data using the paper tape must be managed separately from the data for automatic component insertion. Therefore, there are problems in terms of workability and data management when applying this system to an automatic component insertion system for printed boards of a wide variety of small quantities.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional situation, it is an object of the present invention to provide a taping processing apparatus for inserting parts, which is suitable for automatically inserting parts into printed boards of various types and in small quantities.

[Means for solving problems]

In this invention, as shown in FIG. 1, a data processing system that controls an automatic component insertion machine 1 stores a file storing data related to printed boards and components to be automatically inserted, specifically identification information of inserted components. and a storage file 3 for component insertion schedule data in which the printed board identification information is associated with the number of the storage magazine. This data will also be used in the taping process for inserted parts.

Therefore, the taping data generating device 6 reads the data group from the storage files 2 and 3, edits it into parts data (taping data) in the taping order, and supplies it to the sequencer 10, and the data editing function of the data generating device 6 is activated. An input device 7 for activation is provided.

[Effect]

When the number of the magazine containing the printed board to be automatically inserted is input using the input device 7, the taping data generator 6 first reads out the printed board identification information string related to the magazine number from the component insertion schedule data storage file 3. , perform the first data editing to rearrange the printed board identification information string in the reverse order to the automatic parts insertion order, and then print the same print from the component insertion data storage file 2 according to the changed order of the printed board identification information string. Read the inserted parts identification information string related to the board, perform a second data edit to rearrange the inserted parts identification information string in the reverse order of the automatic parts insertion order, and tape the inserted parts identification information string whose order has been changed. It is sent to the sequencer 10 as data. Sequencer 10
Based on the taping data, the corresponding parts are sequentially taped in the reverse order of the automatic insertion order.

〔Example〕

FIG. 1 is a block diagram conceptually showing an automatic insertion part taping system to which the present invention is applied.
The PTS enclosed in a chain line frame indicates the relevant taping system,
PIS surrounded by a dotted line frame indicates an automatic parts insertion system.

The parts automatic insertion system PIS was originally proposed by the present inventor in Japanese Patent Application Laid-open No. 60-262498 (Japanese Patent Application No. 59-1988).
118888), and as mentioned above, this invention includes an automatic parts insertion machine 1, a parts insertion data storage file 2, a parts insertion schedule data storage file 3, a central processing unit 4, and a data control unit 5.
It is equipped with a data control system consisting of:

Here, the component insertion schedule data and component insertion data stored in the storage files 2 and 3 will be explained in detail with reference to FIGS. 2 and 3.

As shown in Fig. 2, for example, 12 types of printed boards 104A, 104 are automatically inserted on the same day.
Consider a case in which print boards B, 104C, . In this case, the component insertion schedule data is as shown in Figure 3a.
Identification information (drawing number/total edition number) A, B, C, ...L of the 12 types of printed boards 104A to 10L and the number of the magazine 105 that accommodates the printed boards,
, . . . are arranged in the order of component insertion, more precisely, the order of feeding the printed boards to the automatic component insertion machine 1. In addition, the parts insertion data is
As shown in Figure 3b, identification information a1~an, b1~bn, c1~cn, of axial lead parts to be automatically inserted.
... l1 to ln (n=2, 3, . . . ) and the identification information A to L of the printed board on which the component is mounted are arranged in association with each other in the order of automatic insertion. Both of these data are created in advance and filed on a proprietary disk before the day, and loaded into the storage files 2 and 3 on the day.

On the other hand, the automatic insertion component taping system PST according to the present invention shares the component insertion data storage file 2, component insertion schedule data storage file 3, and central processing unit 4, and in particular, the central processing unit 4 generates taping data. It forms a data editing section 61 of the generator 6. In addition, a data control section 62 configured with a microcomputer, which serves as a data transmission/reception section of the data generation device 6, a data storage section 63, an input device 7 consisting of a keyboard device, and a CRT display device 8,
It includes a printer 9 and a sequencer 10 for taping inserted parts.

The data editing section 61 of the taping data generating device 6 is mainly composed of a storage section having six storage areas, in which the editing program is stored in the storage area M1, and the above-mentioned program is stored in the storage area M2. Parts insertion schedule data storage file 3
The printed board identification information string read from the component insertion data storage file 2 is temporarily stored in the storage area M3, and the inserted component identification information string read from the component insertion data storage file 2 is temporarily stored in the storage area M3. In addition, the storage areas M4 and M5 temporarily store the printed circuit board identification information string and the inserted component identification information string, respectively, whose arrangement order has been reversed, that is, whose arrangement has been changed (edited) to the order opposite to the automatic insertion order. . In addition, in the storage area M6, the inserted parts identification information strings arranged in reverse order are separated by printed board unit, and the editing is done so that separation information (space data) * is interposed between the identification information strings for each printed board. The insertion part identification information string, that is, the taping data is temporarily stored.

Note that this data editing section also has a taping data check function. In other words, because only about 1,500 pieces of taping data can be stored due to memory capacity, if the number of taping parts to be inserted into a certain printed board exceeds that number, at that point the sequencer will transfer only the adhesive tape to one conveyor. Feeding 80cm, which corresponds to minutes, results in empty taping. Therefore, in this case, it is necessary to perform the troublesome work of cutting off the empty tape and connecting it in the middle. In this embodiment, in order to avoid this, in the process of storing the taping data in the storage area M6, it is checked for each printed board whether or not the number of pieces of data X is in the relationship of, for example, 1100<X<1500. If so, stop editing the data related to the printed board, transfer the previous taping data of the printed board to the data control unit 62 of the data generator 6 on the terminal side, and check the data of the printed board after taping by the sequencer is completed. I am trying to re-edit the data.

Data control unit 6 of taping data generator 6
2 receives the number of the printed board storage magazine inputted by the input device 7, and instructs the data editing section 61 on the center side to create taping data for the parts related to it, that is, starts data editing. It has a function of temporarily storing the taping data transferred from the data editing section 61 in the data storage section 63 and transmitting the stored data to the sequencer 10.

The CRT display device 8 displays data input via the input device 7 and data output from the taping data generator 6, etc., in Japanese. The printer 9 also prints data such as the display data, identification information of the printed board related to the taping process, the accommodated magazine number, and the number of sheets. The printed material of the taping data is pasted on the surface of the take-up reel of the corresponding taped long adhesive tape, and is used as a heading when the reel is set in the automatic parts insertion machine 1.

Next, the operation of the automatically inserted part taping system PTS having the above configuration will be explained with reference to the flowchart shown in FIG.

First, the input device 7 inputs the numbers of two magazines each containing two types of printed boards (identification information is A, B, C, and D) of four types into which parts should be inserted.
Input by. The input magazine number is received by the data control unit 62 of the taping data generator 6, temporarily stored in the data storage unit 63, and then transferred to the central processing unit 4 in the form of an interrupt.

Data editing section 6 of taping data generator 6
1 reads this transferred magazine number and executes the following data editing and checking processing.

(1) The printed board identification information strings (A B) and (CD) related to the magazine number are read out from the component insertion schedule data storage file 3 and temporarily stored in the storage area M2 (see FIG. 5a).

(2) The printed board identification information string arranged in this automatic insertion order is rearranged in the reverse order and temporarily stored in the storage area M4. [See Figure 5b].

(3) Read the printed board identification information string (DCBA) that is opposite to the stored automatic insertion order, and insert the related inserted parts identification information string (d1, d2,...dn),
(c1, c2,...cn), (b1, b2,...bn), (a1, a2,
...an) is read from the component insertion data storage file 2 and temporarily stored in the storage area M3 (see FIG. 5c).

(4) The inserted parts identification information string arranged in this automatic insertion order is rearranged in the reverse order and temporarily stored in the storage area M5 (see FIG. 5d).

(5) Insert parts identification information string opposite to this stored automatic insertion order (dn…d2d1cn…c2c1bn…b2b1an…
a2a1) is read and edited to insert delimiter information * between the relevant identification information strings for each printed board to create taping data, which is temporarily stored in the storage area M6 (see FIG. 5e).

(6) During this data editing period, the number of data X stored in storage area M6 for each printed board is 1100<X<
Check if it is within the range of 1500.

If not, the previously stored taping data is sent to the data control unit 62 of the data generator 6 on the terminal side with an instruction to stop data editing and re-edit from the data on the printed board. Forward.

(7) If the check result is acceptable and the data editing for the schedule is completed, the taping data (dn...d2d1c*n...c2c1b*n...b2b1) related to the four types of printed boards (identification information A to D) is *
an...a2a1) is transferred to the data control unit 62 with an instruction not to edit data edges. In addition,*
is the space data for empty taping.

The data control section 62 temporarily stores this taping data in the data storage section 63, reads out the stored data, and transmits it to the sequencer 10. Based on this taping data, the sequencer 10 performs a taping operation on inserted parts related to four desired types of printed boards.

One embodiment of the present invention has been described above, but
The present invention is not limited to this, and the following modifications are also possible. That is, the taping data generation device may be constructed independently on the terminal side.

〔effect〕

As is clear from the above description, according to the present invention, taping data can be created with the simple operation of inputting the magazine number that accommodates the printed board into which the component is to be inserted. It has extremely beneficial effects when applied to taping processing for automatic component insertion machines that produce a wide variety of products in small quantities, such as being able to centrally manage data and insertion data for automatic component insertion.
