Abstract
Abstract A mechanism for automatically loading and unloading a printed circuit board from a machine for assembling electronic components to a board. This mechanism receives the board from a board storage magazine and places the board on an X-Y component placement station of the assembly machine. After the components have been placed onto the board, the board is dropped down through the table and transferred back to the storage magazine.

Claim 1
Independent Claim
106 words
A machine for automatically loading and unloading printed circuit boards from an electrical component assembly machine having a component placing station comprising: (a) a board loading mechanism for receiving the board from a board storage means and transferring the board onto the component placing station of the assembly machine; (b) means for unloading an assembled board from the component placing station of the assembly machine; (c) said unloading means including means for returning the assembled board back toward the storage means; (d) said unloading means includes means for dropping the assembled board down through the placing station for returning the board back to the storage means.
Claim 2
Dependent Claim
106 words
A machine for automatically loading and unloading printed circuit boards from an electrical component assembly machine having a component placing station comprising: (a) a board loading mechanism for receiving the board from a board storage means and transferring the board onto the component placing station of the assembly machine; (b) means for unloading an assembled board from the component placing station of the assembly machine; (c) said unloading means including means for returning the assembled board back toward the storage means; (d) said unloading means includes means for dropping the assembled board down through the placing station for returning the board back to the storage means.
Claim 3
Dependent Claim
35 words
