Abstract

This application was developed for batch manufacturing of several different size boards used for a back panel into which printed circuit boards are plugged. The board 9, shown in Fig. 1, is molded plastic with the connector pins precisely positioned. The back side of the board consists of straight pins 10 to which wires are soldered. The front side, onto which the plastic connector housing 11 is placed, consists of an "X"-type configuration 13. Because of this "X"-type configuration, it is vital that the connector housing 11 be precisely positioned at the time of insertion. A slight mis-alignment will cause bending out of the "X"-type contact 13. The back panel board contains two locating holes 15 to establish a precise reference for the positioning of the connectors.

Board and Connector Assembly Using a Precision Alignment Gripper

This application was developed for batch manufacturing of several different size boards used for a back panel into which printed circuit boards are plugged. The board 9, shown in Fig. 1, is molded plastic with the connector pins precisely positioned. The back side of the board consists of straight pins 10 to which wires are soldered. The front side, onto which the plastic connector housing 11 is placed, consists of an "X"-type configuration 13. Because of this "X"-type configuration, it is vital that the connector housing 11 be precisely positioned at the time of insertion. A slight mis-alignment will cause bending out of the "X"- type contact 13. The back panel board contains two locating holes 15 to establish a precise reference for the positioning of the connectors. In this application an adjustable position rotary index table 17 is used, as shown in Fig. 2. A sub-plate 19 is attached to the surface of the rotary index table containing the necessary positioning tooling for the boards being assembled. This sub-plate is easily removed and replaced with another when necessary for a board of different configuration. Since the same gripper is used for all boards, only the sub-plate has to be changed and another operating program entered. In operation, the board is placed on two locating pins 21 in position 23. The rotary index table moves one position at a time until it is located in position 25. The gripper alignment fixture 27 is moved forward upon a precision ball slide 29 by means of an air...
