In addition, the clamping cylinder 5 and the bottom-supporting cylinder 22 can also be electrically connected to the control interface of the articulated arm robot's control system and connected to the articulated arm robot's control system for unified control.

[0034] The front of the fully automatic feeding device for the pole-mounted circuit breaker is reinforced with telescopic rod connecting plate 13 and telescopic rod connecting plate 24, which takes into account the vertical load-bearing capacity and torsional bearing capacity at the end of the telescopic rod, thereby improving the structural strength.

[0035] The fully automatic feeding device for pole-mounted circuit breakers provided in this embodiment of the invention has the following working process:

[0036] The articulated arm robot moves the automatic unloading mechanism to above the pole-mounted circuit breaker receiving station. The initial distance between the push plate 21 and the baffle 11 is greater than the clamping length of the pole-mounted circuit breaker, and the bottom-supporting gripper 20 is in an open state, meaning the bottom-supporting fingers of the bottom-supporting gripper 20 are located in front of the push plate 21. The articulated arm robot moves the bottom-supporting gripper 20 downward to a predetermined position, and the clamping cylinder 5 moves the push plate 21 towards the baffle 11. The push plate 21 and the baffle 11 cooperate to clamp the side of the pole-mounted circuit breaker. The bottom-supporting cylinder 22 rotates the bottom-supporting gripper 20, causing the bottom-supporting fingers of the bottom-supporting gripper 20 to rotate towards the push plate 21, eventually rotating until the bottom-supporting gripper 20 firmly supports the bottom of the pole-mounted circuit breaker. The articulated arm robot moves the pole-mounted circuit breaker to the corresponding position on the tray, and the bottom-supporting gripper 20 and the push plate 21 move in opposite directions to place the pole-mounted circuit breaker on the tray.
