Multi-AGV electric power management system and method based on automatic battery changing

The invention discloses a multi-AGV electric power management system and method based on automatic battery changing. The multi-AGV electric power management system based on automatic battery changingcomprises a battery changing station; the battery changing station has a function of simultaneously charging multiple power-deficient batteries; and a fully-charged battery automatically enters a battery changing waiting area to wait for a next power-deficient AGV to change the battery. The multi-AGV electric power management system based on automatic battery changing further comprises one set ofelectric power management dispatching system. The multi-AGV electric power management system based on automatic battery changing obtains positions of these AGVs and remaining electric powers of the AGVs by communicating with all AGVs in the system and automatically select an appropriate AGV to enter the battery changing station to carry out battery changing operation so as to guarantee that the battery changing efficiency is enhanced while all AGVs runs with safety electric power. Compared with a traditional AGV automatic docking and charging technology, the multi-AGV electric power managementsystem and method based on automatic battery changing has the advantage that the time needed by charging the AGV is greatly compressed by using the battery changing technology. And meanwhile, as thebattery changing station occupying time of single battery changing is very short, the charging waiting time caused by a conflict generated when the multiple AGVs need to be simultaneously charged canbe greatly reduced so that the AGV working efficiency is further enhanced.

Thermosettable Adhesive Tape, Articles And Methods

InactiveUS20090004423A1Concentration of pigment be increaseIncrease usageLamination ancillary operationsLaminationPressure sensitiveChemistry
A thermosettable pressure sensitive adhesive tape comprising at least first and second adhesive layers bonded together. Each of the adhesive layers comprises a thermosettable pressure sensitive adhesive, which is the photo-polymerization reaction product of starting materials. The starting materials for each adhesive layer comprises at least a photo-polymerizable acrylic component and a thermosettable epoxy component. The thermosettable pressure sensitive adhesive, used for either of the two adhesive layers, is not black when fully cured without the presence of a black coloring pigment. The first adhesive layer is made from a layer of starting materials that is thin enough to allow substantial photo-polymerization of the starting materials, even with the starting materials containing a sufficient amount of a black coloring pigment to cause the first adhesive to have a black color after the first adhesive is substantially cured. The second adhesive layer is made from a layer of starting materials which has a thickness that would be sufficiently thick to prevent substantial photo-polymerization (e.g., with UV light) of the starting materials, if the starting materials contained enough of a black coloring pigment to cause the second adhesive to have a black color after the second adhesive is cured.
