Patent ID: 8656583

Claim:
A method for assembling a first component set and a second component set onto a circuit board, the method comprising: forming a slot in the circuit board; driving the circuit board in a first direction; driving the circuit board to an assembling position in a second direction different from the first direction after the circuit board is blocked at a positioning point by a positioning rod, 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; assembling the first component set on a first region of the circuit board when the circuit board is positioned in the assembling position; adjusting the positioning rod to a second width being smaller than the first width, wherein the second width is smaller than the width of the slot; driving the circuit board back to the positioning point after assembling the first component set on the circuit board; driving the circuit board in the first direction until the positioning rod reaches an end of the slot; driving the circuit board to the assembling position in the second direction when the positioning rod reaches the end of the slot; and assembling the second component set on a second region of the circuit board when the circuit board is positioned in the assembling position.
