The application discloses a semiconductor wafer bin conveying system and a control method thereof, and relates to the technical field of semiconductor manufacturing automation. The system comprises a conveying unit and a material placing unit. The improvement lies in that the bottom of a wafer bin body is provided with three positioning grooves in isosceles triangle distribution, forming a mistaken orientation prevention structure; and the transfer frame and the material placing frame are respectively provided with a first set and a second set of limiting protrusions corresponding to the positioning grooves. The two sets of protrusions are configured to be selectively and sequentially clamped with the positioning grooves at the bottom of the same bin body during the conveying process, so that the anti-interference positioning handover from grabbing to placing is realized. The application eliminates the positioning collision risk between the conveying mechanism and the fixed station from the mechanical structure, and ensures the uniqueness of the direction of the wafer bin through the asymmetric geometric design. Meanwhile, the material placing frame can be integrated with elastic air supply and pressure sensing detection functions, realizing higher automation and reliability.

The invention relates to the technical field of explosion-proof electric appliances, and discloses an explosion-proof cable connector with signal triggering, which comprises a plug and a socket, the socket is provided with a switch structure for transmitting signals, the socket is provided with a second mounting plate, the plug is rotatably connected with a first mounting plate, and the first mounting plate is rotatably connected with a second mounting plate. The switch structure is located on a rotation path of the first installation plate, the first installation plate is used for opening and closing the switch structure, the first installation plate is provided with a fastening assembly, and the fastening assembly is used for fixing the first installation plate and the second installation plate. The manufacturing cost of the explosion-proof connector is effectively controlled; when the first mounting plate and the second mounting plate are mutually fixed, the first mounting plate can open and close the switch structure, the switch structure transmits signals, reliable feedback is provided for whether the plug and the socket are firmly fixed or not, and the safety of using the explosion-proof connector is further improved.

The invention relates to a hydraulic slip system with multiple signal feedback and automatic refueling anti-jamming, and belongs to the technical field of oil and gas well drilling and workover equipment.The hydraulic slip system comprises a slip unit and a righting unit, the slip unit is used for opening and clamping a tubular column, and the righting unit is used for achieving radial limiting or centering righting of the tubular column. The slip unit is used for executing opening and clamping of a tubular column, the righting unit is used for achieving radial limiting or centering righting of the tubular column, and the device further comprises a slip inner logic valve set unit and a control part logic unit; the hydraulic valves are connected in series through signals, so that reliable feedback of the clamping and bearing state of the slip body is realized; logic interlocking between the slip body and the centralizing block is established, and clamping of the slip is facilitated; hydraulic logic interlocking is achieved through slip body state signal output; the oil pump is automatically triggered to lubricate under the real bearing working condition of the slip body; under the condition of not depending on electric control and a sensor, the safety and reliability of the system are improved.
