After the hanger 5 reaches the required reaction time, the controller 8 controls the lifting hook of the electric hoist 44 to descend, and when the receiving end of the first reflective photoelectric sensor 81 receives the signal of the transmitting end, the electromagnetic chuck 45 is powered on and the driving motor 7 stops rotating, and controls the motor of the electric hoist 44 to rotate to drive the lifting hook to ascend. When the receiving end of the second reflective photoelectric sensor 83 receives the signal sent by the transmitting end, the controller 8 controls the motor of the electric hoist 44 to stop, i.e. the hook to stop, and controls the motor of the traveling crane 43 to start.
When the rack 5 finishes the whole rack plating process, the rack can move to the end of the rack plating production line under the driving of the travelling crane 43, when the receiving end of the fourth reflective photoelectric sensor 87 receives a signal sent by the transmitting end, the motor of the travelling crane 43 rotates reversely, no response is made to the signal transmitted by the third reflective photoelectric sensor 85, the controller 8 is internally provided with time, the set time is the time for the travelling crane 43 to move from the end to the beginning of the production line, when the set time is reached, the controller 8 controls the motor of the travelling crane 43 to stop, and the controller 8 resets, namely, the counting and timing in the controller 8 are all cleared. Then, after the hanging tool 5 on which the workpiece to be electroplated is hung on the electromagnetic chuck 45, the motor of the traveling crane 43 is started to carry out the next hanging plating.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
