The invention relates to the technical field of LED assembling and machining equipment, in particular to a biaxial suction type automatic lock screw feeder. The screw feeder comprises a machine frame and two triaxial moving assemblies arranged on the machine frame. Each triaxial moving assembly is provided with an electric screw driver, the lower portion of each triaxial moving assembly is provided with a clamp disc capable of rotating intermittently, and each clamp disc is provided with at least two workpiece clamps. In the lock screw machining process, equipment does not need to be shut down, loading, disassembling or replacement of workpieces can be achieved, and machining efficiency of the automatic lock screw feeder is greatly improved. In addition, the two triaxial moving assemblies carry out lock screw machining simultaneously, so that machining efficiency is further doubled, and practicability is high. The workpieces machined through the screw feeder can be mobile phone shells, tablet personal computer shells, navigator shells, routers, set top boxes and other electronic products.

The invention provides a rail-switching operation vehicle and a rail-switching transport vehicle set. The rail-switching operation vehicle comprises steering frames and a vehicle body underframe arranged on the steering frames, wherein running rails allowing a hoisting vehicle to travel and first steel rail guide grooves for accommodating steel rails to be switched are arranged / formed on / in the top surface of the vehicle body underframe; and the rail-switching operation vehicle further comprises a first steel rail guide device and a second steel rail guide device for guiding the steel rails to be switched to enter in or move out from the corresponding first steel rail guide grooves. The rail-switching operation vehicle provides an opening space for collecting operation and unloading operation of the steel rails for the hoisting vehicle, during steel rail unloading operation, the steel rails can be unloaded to preset unloading positions; during rail collecting operation, recovery of old steel rails is guided, so that the loading and the unloading of the steel rails to be switched are realized, the mechanized and automatic degree of the rail-switching operation is greatly increased, and the working efficiency is improved; and the labor intensity is reduced, the manning levels are reduced, the quality of rail-switching operation can also be improved, and requirements for urban construction and rail traffic development at current are met.

The invention provides a fluorescent encoding microsphere, an array and a preparation method of the fluorescent encoding microsphere. The encoding microsphere comprises a microsphere carrier, which isa mesoporous microsphere, wherein the microsphere carrier is internally provided with at least one fluorescent marker, the fluorescent marker is formed by connecting a fluorescent dye and an intermediate substance, and the central emission wavelengths of the fluorescent dyes corresponding to the fluorescent markers are different, so that each fluorescent dye defines the coding information of onedimension of the coding microsphere.

The invention relates to a box body quick-detaching cargo hold loaded on an unmanned aerial vehicle. 55 g steering engines and gear sets are respectively mounted on the top surfaces and the side surfaces of a cargo hold body; the 55 g steering engine I is connected with the gear set II in a transmission manner through a steering engine connecting piece I and a long steering engine transmission rod; the 55 g steering engine II is connected with the gear set I in a transmission manner through a steering engine connecting piece II and a short steering engine transmission rod; the gear sets II andI are respectively connected with a cargo hold bottom door set and a cargo hold front door set through connecting pieces capable of bearing loads; a cross-shaped slide rail in a crank guide rail mechanism is mounted at the top of the cargo hold body; unmanned aerial vehicle cargo hold quick matching and connecting mechanisms are respectively arranged in four slide grooves in the cross-shaped slide rail in a matched manner; a vertical rod in each unmanned aerial vehicle cargo hold quick matching and connecting mechanism is connected with the slide groove in the cross-shaped slide rail to forma moving pair; a rotatable cargo hold transmission cross plate is connected to the cross-shaped slide rail; the verticals are connected to the rotatable cargo hold transmission cross plate through transmission rods; and the four unmanned aerial vehicle cargo hold quick matching and connecting mechanisms connect the whole cargo hold to the unmanned aerial vehicle.

The invention discloses a falling device of a logistics unmanned aerial vehicle. The device comprises a fixing frame, a power supply part, a supporting plate, an electromagnet, a pallet and an attraction plate, the top of the fixing frame is connected with the bottom of the unmanned aerial vehicle, the bottom of the fixing frame is connected with the supporting plate, the power supply part is arranged between the fixing frame and the supporting plate, the electromagnet is connected to the bottom of the supporting plate, the attraction plate is arranged at the top of the pallet, the pallet is connected with goods, and the attraction plate corresponds to the electromagnet. In the loading and unloading process, an operator does not need to load and unload goods to the unmanned aerial vehicleand only needs to connect the goods with the pallet, the unmanned aerial vehicle attracts the attraction plate on the pallet through the electromagnet, loading of the goods by the unmanned aerial vehicle is achieved, meanwhile, the electromagnet is powered off by the power supply part, the attraction plate is disconnected, unloading of the goods by the unmanned aerial vehicle is achieved, and loading and unloading are convenient.
