However, in the above-mentioned conventional main wiring board device, there is only one pin insertion / removal robot for the matrix boards arranged in a large number on the plane, and this one pin insertion / removal robot is used. Therefore, it is necessary to insert the connection pins into the pin insertion holes of the matrix board of each of the primary, secondary and tertiary groups, so not only is the connection processing time consuming, but it is also time-consuming to release the connection. However, there is a problem in that efficiency is poor because multiple connections cannot be made simultaneously.

Also, since there is only one pin insertion / removal robot, if a failure occurs in this robot, the operation of the entire device must be stopped during repair, and many subscribers who wish to be newly installed or relocated. There was also the problem of causing trouble. Further, in the pin insertion / removal robot, it is necessary to move the robot hand together with the movable table over a length of several meters in the X-axis and Y-axis directions, and for a pin insertion hole having a diameter of 1 mm or less, Since it is necessary to align the pin of the gripping claw of the robot hand within the range of ± 0.1 mm and insert and remove the connecting pin, it is necessary to achieve high speed and high accuracy at the same time. There is also a problem that it is expensive because a large motor etc. is required, and there is also a problem that the pin insertion / removal robot becomes large and power consumption is large.

Furthermore, in order to search the position of the target pin insertion hole, it is necessary to attach a gold plate corresponding to the sensor and an index pattern to a large number of matrix boards, which also causes a problem that the device becomes expensive. In addition to this, there is a problem that the pin insertion / removal robot is large and heavy, so that it is difficult to carry and install.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an explanatory view showing an array connection example of a matrix board 1. First, referring to FIG. 2, reference numeral 1 denotes a matrix board. The matrix board 1 arranges input lines and output lines in different planes in a grid pattern and has pin insertion holes at the intersections of the input lines and output lines. As a structure provided, by inserting a connection pin made of a conductor or provided with a conductor into an arbitrary pin insertion hole, an input line and an output line corresponding to the pin insertion hole are connected.

Here, the total number of matrix boards 1 to be used is 176, and the 176 matrix boards 1 are divided into three groups of primary, secondary and tertiary, and the number of primary groups is 64. Similarly, the number of secondary groups is 64, and the number of tertiary groups is 48. In addition, the matrix board 1 of the primary group has 50 input lines and 64 output lines.

The output lines are connected to the input lines of the 64 matrix boards 1 of the secondary group one by one (one input line and output line is one pair line), and each matrix board 1 of the secondary group is connected. Of 4
48 matrix boards 1 of 8th output line 3rd order group
One is connected to each input line.

In this way, the input lines and output lines of the matrix boards 1 of each group are connected, and the input lines of each matrix board 1 of the primary group are connected to the subscriber side of each matrix board 1 of the tertiary group. If the output line is on the exchange side, when connecting the input line of the matrix board 1 having the primary group and the output line of the matrix board 1 having the tertiary group, the pin insertion of the matrix board 1 in each group The input line and the output line can be connected by appropriately selecting the holes and inserting the connection pins.

Next, the structure of FIG. 1 will be described.
Is a mother board, and the matrix boards 1 described with reference to FIG. 2 are attached to the mother board in blocks of a predetermined number. For example, since there are 64 matrix boards 1 in the primary group, 8 boards are divided into 8 blocks, which are attached to the mother board 2.

Similarly, the 64 matrix boards 1 of the secondary group are also divided into 8 blocks and attached to the mother board 2, and the 48 matrix boards 1 of the tertiary group are further divided into 6 blocks. And is attached to the motherboard 2. The matrix board 1 of each block is connected by wiring on the back side of the mother board, but if a printed wiring board having a size of eight matrix boards is used to connect in block units, the wiring of each group will be It is simplified and the whole wiring becomes easy.

Reference numeral 3 denotes a pin insertion / extraction robot formed in a small XY plotter type. The pin insertion / extraction robot 3 has an outer shape portion formed by assembling a pair of X frames 4 and connecting frames 5 into a rectangular frame shape. The X frame 4 includes a Y frame 6 provided so as to extend between the pair of X frames 4 and a robot hand portion 7 provided on the Y frame 6 and having a pair of openable and closable gripping portions. The outer shape portion including the connecting frame 5 corresponds to the size of one block by the eight matrix boards 1.

The Y frame 6 is moved along the X frame 4 in the X axis direction by an X axis motor (not shown) attached to the X frame 4 and its power transmission mechanism. The robot hand unit 7 also moves in the X-axis direction together with the frame 6. The robot hand section 7 is moved in the Y-axis direction along the Y-frame 11 by a Y-axis motor (not shown) attached to the Y-frame 6 and its power transmission mechanism.

Therefore, the robot hand portion 7 can freely move in the X and Y axis directions within a rectangular plane area defined by the outer shape portion including the X frame 4 and the connecting frame 5. Further, a Z-axis motor, a power transmission mechanism therefor, and a Z-axis guide are assembled to the robot hand unit 7, so that the robot hand unit 7 can be moved in the Z-axis direction. A motor for opening and closing the hand and the like are also attached to the section 7.

A small stepping motor is used as the motor for each axis and the motor for opening and closing the hand. In this example, the pin insertion / removal robot 3 is installed close to and facing each block of the matrix board 1. In this example, as described above, the matrix board 1 of the primary, secondary, and tertiary groups is Since the total number of blocks is 22, therefore, 22 pin insertion / removal robots 3 are used, and one pin insertion / removal robot 3 is assigned to one block of the matrix board 1.

The operation of each of these robots is controlled by a control means (not shown). Further, in this example, the Y frame 6 and the robot hand unit 7 of each pin insertion / removal robot 3 are composed of eight matrix boards 1
Since the movement amount is small within the range of one block consisting of, the relative error with respect to the pin insertion hole of each matrix board 1 also becomes small, and the Y frame 6 and the robot hand portion 7 are moved along the X axis and Since a stepping motor is used for the Y-axis motor,
By controlling the pulse applied to the stepping motor, the Y frame 6 and the robot hand unit 7 can be moved with high accuracy.

The position of the robot hand unit 7 can be grasped as XY coordinates within the range of one block from the driving amount of the stepping motor, and therefore the current position of the robot hand unit 7 is held as data. Then, by applying a pulse to the X-axis and Y-axis motors based on the current position data, it is possible to make the gripping claws of the robot hand section 7 face the target pin insertion hole.

Next, the operation of the above configuration will be described. When connecting the input line in the matrix board 1 having the primary group and the output line in the matrix board 1 having the tertiary group, first, the control means (not shown) uses the input / output line of the matrix board 1 in each group. The situation is monitored, the matrix board 1 and the pin insertion hole in each group for connecting the input line and the output line are selected, and three pin insertion / extraction robots 3 corresponding to the selected matrix board 1 are selected. The gripping claws of the robot hand unit 6 are caused to grip the connection pins, respectively.

That is, here, the three pin insertion / extraction robots 3 corresponding to the blocks including the selected matrix board 1 of each group are simultaneously driven, and the robot hand unit 6 is operated.
The connection claws are made to be gripped by the respective grip claws. In each block, this connection pin is inserted into a through hole provided separately from the pin insertion hole in the predetermined matrix board 1 for moving the Y frame 6 in the X axis direction and at the same time as the robot hand section 7. By moving in the Y-axis direction, the gripping claw of the robot hand unit 7 is positioned at a position facing the connection pin inserted in the through hole, the robot hand unit 7 is moved in the Z-axis direction, and at the same time, the gripping claw is moved. The connection pin is held by the holding claw by opening and closing.

Next, the Y frames 6 of the three pin insertion / removal robots 3 are moved in the X axis direction, respectively, and
By moving each robot hand unit 7 in the Y-axis direction, the gripping claw of each robot hand unit 7 faces the pin insertion hole of the target matrix board 1.
Subsequently, the robot hand units 7 of the three pin insertion / removal robots 3 are moved in the Z-axis direction so as to approach the matrix board 1, and thereby the connection pin grasped by the grasping claws is the pin insertion hole for the purpose. Respectively, after inserting,
Open the grip claws to release the connecting pins.

As a result, the matrix board 1 of the primary group
Input line and the output line of the matrix board 1 of the third group are connected to each other to connect the telephone and the telephone exchange. In this way, in this example, when one input line of the matrix board 1 of the primary group and one output line of the matrix board 1 of the tertiary group are connected, the primary, secondary, and tertiary By simultaneously operating the three pin insertion / extraction robots 3 of each group, the connection pins are inserted into the target pin insertion holes of the matrix board 1 of each of the primary, secondary, and tertiary groups. Since the input line and the output line are connected, it is possible to connect the input line and the output line at a speed almost three times faster than the conventional one.

When two or more input lines of the matrix board 1 of the primary group and the same number of output lines of the matrix board 1 of the tertiary group are connected, the number of connection lines corresponding to the number is 1
If the pin insertion / removal robots 3 of each of the secondary, secondary, and tertiary groups are operated at the same time, the connection can be performed at the speed of the number of connections. FIG. 3 is a perspective view showing another embodiment of the main wiring board device according to the present invention.

In this embodiment, eight matrix boards 1 are attached to a small motherboard 8 to form a block,
The blocks are arranged in parallel, and the pin insertion / extraction robot 3 is arranged between the blocks to face the matrix board 1. In this configuration,
The matrix boards 1 of each of the next and third groups are connected in the same manner as in the embodiments of FIGS. 1 and 2, and
By simultaneously driving the pin insertion / extraction robots 3 corresponding to the secondary and tertiary groups, the matrix board 1 input lines and 3 of the primary group are driven.
The output lines of the matrix board 1 of the next group can be connected. In this embodiment, the blocks are arranged so that the matrix boards 1 of the adjacent blocks face each other, and the robot hand unit 7 of the pin insertion / removal robot 3 provided between the blocks of the matrix board 1 of the opposing block is arranged. If the connection pins can be inserted into and removed from both pin insertion holes, the number of pin insertion / extraction robots 3 to be used can be reduced to approximately half.

In the above embodiment, the total number of matrix boards 1 is 176, and the 176 matrix boards 1 are divided into three groups of the primary, secondary, and tertiary groups. The number of sheets is 64, the number of secondary groups is also 64,
Although the description has been made assuming that the number of groups of the third order is 48 and the number of matrix boards 1 in one block is eight, the present invention is not limited to this, and the total number of matrix boards 1, the number of groups, and one block Matrix board 1
Can be arbitrarily changed, and when the number of matrix boards 1 in one block is changed, the size of the pin insertion / removal robot 3 may be changed according to the size.

[0032]

As described above, according to the present invention, the matrix board of each group is divided into a plurality of blocks for every certain number of blocks, and the blocks are moved in the X-axis, Y-axis and Z-axis directions within the range of one block. A pin insertion / removal robot having a robot hand portion for inserting / removing the connection pin is provided for each block, and at least one pin insertion / removal robot in each group is simultaneously driven to form a pin insertion hole in the matrix board of each group. By inserting the connection pin into the input line of the matrix board of the first group and the output line of the matrix board of the last group, the connection process can be performed in a short time. Since a plurality of connections can be performed at the same time, the effect of improving the efficiency of connection processing can be obtained.

Further, since a pin insertion / removal robot is provided for each block composed of a plurality of matrix boards, even if a failure occurs in the robot, it is connected to the block which the robot takes charge during repair and the matrix board of the block. Also, since it is possible to connect to other matrix boards only by making some matrix boards unusable, it is possible to minimize the annoyance to telephone subscribers without stopping the operation of the entire device. You can also get the effect.

Since the pin insertion / removal robot is provided for each block composed of a plurality of matrix boards, a small one can be used and a small stepping motor can be used as a motor for moving the robot hand portion. Moreover, the movement amount of the robot hand portion of each pin insertion / removal robot is small, and therefore the relative error with respect to the pin insertion hole of each matrix board is small, and the stepping is performed on the X-axis and Y-axis motors for moving the robot hand portion. Since a motor is used, it is possible to move the robot hand part with high accuracy by controlling the pulse given to this stepping motor. Therefore, even if a certain number of pin insertion / removal robots are required, it will be cheaper overall. Also, considering the number of robots driven at one time, Effect that power is also reduced can be obtained.

Further, as described above, the robot hand portion of the pin insertion / extraction robot can be moved accurately by controlling the pulse given to the stepping motor for movement, so that the position of the target pin insertion hole is searched. Therefore, it is not necessary to attach a sensor-compatible gold plating and index pattern to a large number of matrix boards, and the device can be made inexpensive in this respect as well, and each pin insertion / extraction robot is small and lightweight. Therefore, the effect that the transportability and the installability are also improved can be expected.
