Abstract

The arrangement consists of automatically registering while feeding different length printed circuit PC boards from one direction to another without changing hard tooling. Damage to the printed circuits on the boards is avoided because multi-directional rollers are utilized. In an automated PC board manufacturing environment, material handling is very important. In this article methods are set forth to automatically feed boards of different sizes from a commercial loading magazine to the board testing station which are perpendicular to each other. As seen in the drawing, batches of PC boards 10 of different lengths are manually loaded at Station A which is a commercial board-loading magazine. After a board is fed to position 1, cylinder 12, which is attached to the platform, is extended to swing the attached arm 13 around.

Simultaneously Feed and Register PC Boards of Variable Sizes for Automated Board Testing

The arrangement consists of automatically registering while feeding different length printed circuit PC boards from one direction to another without changing hard tooling. Damage to the printed circuits on the boards is avoided because multi-directional rollers are utilized. In an automated PC board manufacturing environment, material handling is very important. In this article methods are set forth to automatically feed boards of different sizes from a commercial loading magazine to the board testing station which are perpendicular to each other. As seen in the drawing, batches of PC boards 10 of different lengths are manually loaded at Station A which is a commercial board-loading magazine. After a board is fed to position 1, cylinder 12, which is attached to the platform, is extended to swing the attached arm 13 around. Roller 14, attached at the end of arm 13, eventually pushes the board forward in the x-direction until it reaches the registration rollers 15. Arm 13 stays in position and applies a slight force against the edge of board 10 for registration. Since arm 13 swings in an arc, different lengths of board can be fed and registered in the same manner. Once the edge of the board reaches the registration rollers 15, the platform 16 is signalled to shuttle smoothly forward in the y-direction. Simultaneously, the PC board 10 is precisely fed to testing station B in the...
