[Industrial application field]

TECHNICAL FIELD The present invention relates to a printed wiring board wiring connection instruction device used to change the wiring of a printed wiring board and to connect wiring using connection lines.

The present invention relates to a printed wiring board wiring connection instruction device used for changing wiring on a printed wiring board.

BACKGROUND OF THE INVENTION It is sometimes necessary to make circuit changes in printed wiring boards that constitute electronic circuits.

In this case, in addition to changing component constants and deleting circuit wiring,
May involve adding or changing wiring.

It is often necessary to change this wiring by soldering connection wires to the printed wiring board, and the most important aspect of this work is to connect accurately and without errors to the high-density printed wiring. Ru.

[Conventional technology]

Fig. 3 shows an example of a conventional wiring connection indicator, and Fig. 4 (a) -
(C1 shows a working state diagram on the printed wiring board, and FIG. 5 shows a cross-sectional view of wiring connections.

Due to circuit changes, printed wiring board 1 as shown in Figure 4 (al)
When connecting the three connection points 2A, 2B, and 2C with short circuit wiring, connect the connection points 2A and 2B with the wiring 4A, and connect the connection point 2.
B.

20 are connected by wires 4B, but in reality, the printed wiring board 1 is highly densely mounted, and it is not easy to find the connection points 2^, 2B, and 2G accurately. Therefore, an indicator like the one shown in Fig. 3 is used.

This indicator 9 includes a panel surface 91 on which the printed wiring board 1 is installed at a reference position, a light projecting section 31 on top of which emits a light beam 3 to an arbitrarily specified position on the panel surface 91, and a CAD/CAM change connection. It includes a built-in control section 81 that receives data and controls the projection position of the light beam 3 on the printed wiring board 1, and is composed of a vertical switch 71 connected to this control section 81.

Place the printed wiring board 1 in the position determined by the front and back sides, and press the foot switch 71 to start.
According to the connection data, for example connection point 2A.

2B, the light beam 3 reciprocates linearly to connect the connection points 2A and 2B on the printed wiring board 1 as shown in the dotted line, as shown in FIG. Therefore, all you have to do is connect with the wiring 4A using the specified start and end points as connection points. When finished, press the foot switch 71 again.
Step on the button, project the light beam 3 onto the printed wiring board 1 according to the next connection data, for example, as shown by the dotted line in FIG.・
Step on Noto Sui Nochi 71. Repeat this until all of the changed connection data is completed, and then press the last foot switch 7.
When the user presses step 1, the end is known by the buzzer sound and the fact that the light beam 3 is not emitted.

In this way, the connection instructions are accurately given, and there are no omissions due to oversights in the work.

[Problem to be solved by the invention]

However, in the case of the connection shown in Figure 4(a), ■
Wiring 4A and wiring 4B have separate connection data, and as shown in Figure 5, after working on wiring 4A, instructions for wiring 4B are given, and at the common connection point 2B, the solder at the -degree soldered location is The wiring 4B cannot be connected and soldered unless it is removed by suction to expose the connection terminal.

- As described above, since it is not known whether or not there are duplicate connections in continuous wiring, subsequent work always involves re-soldering, which is a wasteful and unreasonable task.

There were problems such as.

In view of this problem, the present invention has been made with the object of providing a wiring connection instruction device that eliminates the need for redundant soldering at duplicate connection points.

[Means to solve the problem]

As shown in FIG. 1, the above problem is caused by the connection between a storage device 6 that has connection data for a plurality of wirings, an input device 7 that instructs to read out necessary connection data related to the printed wiring board 1 from the storage device 6, and It consists of a calculation device 8 that creates coordinate instruction data from the data, and an indicator 9 that can move and blink the light beam 3 based on the coordinate instruction data, and organizes all the read connection data in the calculation device 8. Then, the continuous connections are divided into groups, and the order for each group is set as the means. Within the same group, the connection data where the connection point 2 is the same is set as the continuous order, and the final connection data in that order is Problems other than the above can be solved by the printed wiring board wiring connection indicating device of the present invention, which is equipped with a continuous ordering means for adding further data to the coordinate instruction data so as to blink and display the connection point 2 that is a duplicate connection. be done.

[For production]

That is, the purpose is achieved because duplicate connection points are found from the connection data, the presence of subsequent duplicate work is displayed at the same connection point, and the order of continuous work is established.

FIG. 1 fa) shows a basic configuration diagram of the present invention, and FIG.

The design department can request changes for each manufacturing loft at once.
Since the D data is issued, the data regarding the printed wiring board 1 is stored in the storage device 6 based on this pattern change data. Therefore, to change the wiring of the corresponding printed wiring board 1, operate the input device 7 and, for example, , when the type symbol of the corresponding printed wiring board 1 is entered manually, all the corresponding connection data are read out and accepted into the arithmetic unit 8.

In this arithmetic unit 8, all of this connection data is organized and
The grouping method determines the grouping of continuous connections and the order of each group. This is because connection data is data that connects two connection points, and connection data that includes the same connection point forms the same group, resulting in a continuous connection.

Next, by using the sequential ordering means, the same group is sorted, and the connection data in which the connection point 2 is the same is placed in a continuous order, and the connection data other than the last connection data in that order, that is, the connection points with subsequent duplicate connections. 2, further data is added to the coordinate instruction data so as to display it blinking.

Based on the output data of the calculation device 8, the indicator 9 controls the light beam 3 from the light projector 31 to a specified position on the installed printed wiring board 1, and sets the position of the two connection points 2 as the starting point. , if the terminal moves back and forth and involves subsequent duplicate connection work at any of the connection points 2, the operator is notified by flashing the connection point 2 using the above-mentioned additional data;
Until there are no successors, only connect them to the terminals, etc., and put the soldering on hold.The last connection instruction that is displayed continuously at the connection point 2 causes the final soldering to be performed once.

In this way, it is possible to provide a wiring connection instruction device that eliminates redundant soldering work at redundant connection points.

〔Example〕

The present invention will be specifically described below with reference to embodiments shown in the drawings.

The same reference numerals indicate the same objects throughout the figures.

Fig. 2 fal shows the original connection data table of an embodiment of the present invention, the same figure (bl shows the same connection diagram, and the same figure (C1 shows the same group sequential order table).

Note that the external appearance of this indicator is the same as that shown in FIG. 3 described above, and the configuration is the same as that shown in FIG. 1 described above, so a description thereof will be omitted.

Figure 2 (as shown in BL, multiple wiring lines 4
When connecting A, 4B, 4C...4I, storage device 6
An original connection data table as shown in FIG. 2 [a] is stored for each type of printed wiring board 1. This data is, for example, processed data output from CAD or the like.

(2) When the type of printed wiring board 1 is input from the input device 7, the arithmetic device 8 reads the corresponding connection data from the storage device 6, and the original connection data table shown in FIG. 2(a) is completed. At this time, the order of the data remains the same as the order of storage in the storage device 6, and the two connection points for each wire are indicated by symbols and numbers.

? (2) The arithmetic unit searches for a wire that has the same connection point as the connection point 1 of the first wire A in the connection data table.Since there is none in this case, it also searches for the connection point 8 on the other side. This time, since the wiring H is applicable, the wiring H is selected as the next wiring connection order, and continuous wiring is performed as a continuous order work.

(2) Similarly, in the wiring order after wiring H, wiring F is selected consecutively, but after that, wiring to the same connection point is not continued. Therefore, to the previous wiring.

1 (, F was continuous wiring and was in the same group.

■ Next, the remaining topmost wire B is picked up from the connection data table as a new group, and then the wire i at the same connection point is selected, but there is no successor, and wires B and E are in the same group and are continuous. It becomes wiring.

② Wirings are similarly selected and rearranged in that order to create a continuous order table as shown in Figure 2 (for the ClO group).

(2) Furthermore, when determining the wiring order of the same group, a flag is set at the same connection point where the subsequent wiring is selected, and data is added at the same time.

As a result, a flag is set at any connection point for all but the last wire.

■ The arithmetic unit 8 further extracts the wiring connection data in accordance with the order of this connection data table, converts the symbols of the two connection points into coordinate position data on the printed wiring Fj, 1, and further calculates the The presence/absence of flag data is added and output to the indicator 9.

■ The indicator 9 moves the light projector 31 based on the coordinate position data.
is driven, and the light beam 3 is projected back and forth between the connection points 2 at specified positions on the printed wiring board 1 installed on the panel surface 91.

Further, at the connection point 2 where flag data is present, light is emitted intermittently and displayed in a blinking manner.

■ By moving the light beam 3, the operator knows the position where the wiring should be connected, and by the flashing of the light beam 3 at the end point, the operator knows that there is a subsequent duplicate connection. I'll put the soldering on hold until then.

[Phase] After completing the - wiring, the worker operates the foot switch 71 to receive the next wiring instruction and work.
At this time, the connection points 2, for which soldering was deferred in the previous wiring 4, are displayed continuously this time, so soldering can be performed.

■ Repeat the following steps until all wiring connections are completed.

In this example, each connection point was connected in a single stroke, but as design change data, in the case of a wiring connection that has three or four branches at a connection point, it is possible to connect two points at the shortest distance. For single-stroke connections that do not have three or more branches, the connected data that has been converted is used in this machine, or in this example, it is grouped as two overlapping connection points and arranged in the wiring order of continuous connections. If there are 3 or more duplicates, the selection will be incomplete, so
Furthermore, connection points that appear three or more times from all connection data are created as a multiple connection point table along with the number of times, and the above group is created when creating a continuous order table, and after finishing for the same group,
Before moving to a new group, count the number of connections of the connection point corresponding to this multiple connection point table, and if it is insufficient, select other wiring of the same connection point from the original connection data table and arrange them.
Repeat until the same number of connections is reached, and then select and arrange them. At this time, by setting a flag at the same connection point of the nearest higher-level wiring, it is also possible to perform a wiring connection including three or more branches.

〔Effect of the invention〕

As described above, if the present invention is used, there is no need for a wiring diagram,
Connect the wires in the order indicated by the light beam of the indicator, hold off on soldering when it flashes, and continue soldering when it continues, so you can complete the work without any mistakes, and avoid wasted or unreasonable redundant soldering at duplicate connection points. This has enabled efficient and accurate work to be avoided.
