Abstract:
An alignment device for electrically connecting a testing device to a socket of a sliding plate, the sliding plate slidably placed on a conveyer that can be temporarily halted in front of the testing device, the alignment device comprising:a positioning device fixed on the socket of the sliding plate, the positioning device comprising a positioning hole with a substantially rectangular shaped recess, and a funnel shaped neck portion disposed over the positioning hole; a plug electrically connected to the testing device; a guiding device fixed on the plug, the guiding device comprising a guiding pole with a substantially rectangular shaped head, the position of the guiding pole corresponding to the position of the positioning hole; a driving device installed beside the testing device for pushing the plug and the guiding device separately toward the socket and the positioning device of the sliding plate; and a mounting device installed on the driving device for slidably supporting the plug and the guiding device so that the plug and the guiding device are slidable in a two-dimensional plane to align the plug along an x-direction and a y-direction with the socket; wherein the guiding device is used for interacting with the positioning device for adjusting a position of the plug relative to the socket, when the plug is pushed toward the socket of the sliding plate by the driving device, the guiding pole is guided by the funnel shaped neck portion into the positioning hole, and the substantially rectangular shaped head of the guiding pole is guided into the substantially rectangular shaped recess of the positioning hole, a shape of the substantially rectangular shaped head and a shape of the substantially rectangular shaped recess causing the guiding pole to align with the positioning hole to adjust the position of the plug on the mounting device so that the plug can be plugged into the socket of the sliding plate.
