Patent ID: 7373718

Claim:
A test device for a heat dissipating fan, which is suitable for testing if a fan wheel is assembled to a housing of the heat dissipating fan firmly, comprising: a vertical support post; a transverse slide unit, being disposed at the top of the support post, providing a transverse slide actuating piece and a transverse slide seat, which is actuated by the transverse slide actuating piece; a vertical slide unit, providing a vertical slide actuating piece at the transverse slide seat and a vertical slide seat, which is actuated by the vertical slide actuating piece; a clamping unit, moving with the vertical slide seat for clamping the housing; a suction unit, moving with the vertical slide seat for absorbing the fan wheel; and a sensing element, moving with the vertical slide seat and being disposed near the suction unit for sensing if the suction unit is able to absorb and move the fan wheel upward; wherein, the vertical slide seat moves downward to approach the heat dissipating fan while the vertical slide actuating piece is driven; then, the clamping unit clamps the housing and the suction unit absorbs the fan wheel; the sensing element sends out a signal to the clamping unit and the suction unit to terminate operations of clamp and suction in case of the suction unit being incapable of sucking the fan wheel to move upward; and the transverse slide actuating piece is driven to carry the heat dissipating fan away in case of the fan wheel is sucked to move upward.
