Abstract
The invention discloses a fusion splice leakage protective system for a point welding machine. The system comprises a bottom fusion splice, a top fusion splice, the point welding machine, a first photoelectric sensor, a proximity sensor, a second photoelectric sensor and a controller. The top fusion splice is located above the bottom fusion splice and can move up and down. The point welding machine compresses and powers up a fused object transferred between the bottom fusion splice and the top fusion splice for fusion welding. The first photoelectric sensor is arranged on one side of the point welding machine to be used for sensing the state of the thrown-in fused object. After the top fusion splice is powered up, the fused object is transferred between the top fusion splice and the bottom fusion splice, and when the top fusion splice descends, the proximity sensor is used for recognizing the power-up state. The second photoelectric sensor is arranged on the other side of the point welding machine to be used for sensing the state of the fused object which is transferred and discharged from the point welding machine. All sensors input the weekly counting set price, the weekly counting output price is input according to the sequential operations to the first photoelectric sensor, the proximity sensor and the second photoelectric sensor, the set price and the output price are compared, and then the controller controls the operation of the top fusion splice.
