Abstract

An automatic main distributing frame (MDF) apparatus for connecting and disconnecting an exchange and a user terminal includes a first-staged matrix board having a plurality of input/output lines, the input/output lines being disposed in a matrix pattern. The MDF apparatus also includes second-staged and third-staged matrix boards having a plurality of input/output lines, the input/output lines also being disposed in matrix patterns. The second-staged matrix board is disposed perpendicular to the first matrix board and the third-staged matrix board is disposed perpendicular to the second matrix board. A center board is disposed between the first-staged matrix board and the second-staged matrix board and between the second-staged matrix board and the third-staged matrix board. The center board, the first-staged matrix board, the second-staged matrix board, and the third-staged matrix board are mutually connected through connectors.

An automatic MDF apparatus having an automatic connection pin inserting/removing robot control unit, comprising:

a plurality of matrix boards having pin holes into which connection pins are inserted, the pin holes being formed in a matrix pattern in the X axis direction and the Y axis direction;
a robot hand portion for holding and releasing a connection pin;
a zero point position alignment portion disposed at one edge of a moving region of said robot hand portion;
a reference pin disposed on a matrix board in the vicinity of said zero point position alignment portion;
a measurement pin disposed on a matrix board different from the matrix board having said reference pin;
detecting means for detecting whether said robot hand portion holds or releases said reference pin and said measurement pin;
first storage means for storing compensation data for an amount of movement of said robot hand portion in the Y axis direction;
second storage means for storing compensation data for an amount of movement of said robot hand portion in the Y axis direction;
calculating means for calculating the amount of movement of said robot hand portion, moving said robot hand portion from said zero point position alignment portion in the X axis direction and the Y axis direction, repeating the moving operation of said robot hand portion until said robot hand portion holds said reference pin, and calculating the amount of relative deviation between said robot hand portion and said measurement pin in the X axis direction and the Y axis direction;
and
control means for controlling the moving amount of said robot hand portion in the X axis direction and the Y axis direction corresponding to the compensation data stored in said first storage means and said second storage means so as to align said robot hand portion to a particular pin hole when the connection pin is inserted or removed into/from the particular pin hole of the matrix board.
