Patent ID: 8387233

Claim:
A circuit board assembling system comprising: a circuit board whereon a slot is formed, the circuit board comprising a first region and a second region; a component placement machine for assembling components on the circuit board; a positioning rod disposed on a positioning point in a adjustable manner, wherein a first width of the unadjusted positioning rod is larger than a width of the slot so that the unadjusted positioning rod can not pass through the slot; a conveying device for driving the circuit board to the positioning point in a first direction and driving the circuit board to an assembling position in a second direction different from the first direction; and a control unit for controlling the conveying device to drive the circuit board to the assembling position in the second direction and controlling the component placement machine to assemble a first component set on the first region of the circuit board when the circuit board is blocked at the positioning point by the positioning rod, for controlling the positioning rod to be adjusted from the first width to a second width being smaller than the width of the slot, for controlling the conveying device to drive the circuit board back to the positioning point and to drive the circuit board in the first direction until the positioning rod reaches an end of the slot after the first component set is assembled on the circuit board, and for controlling the conveying device to drive the circuit board to the assembling position in the second direction and controlling the component placement machine to assemble a second component set on the second region of the circuit board.
