The invention discloses an intelligent book management and pick-and-place system. A book holder is arranged on each bookshelf, and a book is correspondingly placed on each book holder. A control system controls an electric push rod and a weight sensor to drive the book holder to slide back and forth relative to the bookshelf, and a user is reminded of the location of the book and can conveniently pick the book. According to the invention, the structure of the bookshelf is optimized; and due to the book placing manner and the design of the control system, book management and pick-and-place are quick, convenient, intelligent and humane.

The invention belongs to the technical field of batteries, and specifically discloses a preparation method of a lithium manganese phosphate / carbon composite material with a nano-micro hierarchical structure, which will contain a manganese source, a lithium source, a phosphorus source, hexamethylenetetramine, ethylene glycol The raw material solution is heat-treated at 70°C to 80°C in advance, and then solvothermally obtained at 160°C to 200°C. The prepared lithium manganese phosphate material with nano-micro hierarchical structure is mixed with a polymer carbon source, dried and calcined at 500°C to 650°C in a protective atmosphere. The primary particles of the material prepared by the invention are nano-scale, have preferential growth and uniform distribution, and are beneficial to the diffusion of lithium ions in the material. The size of the secondary particles is at the micron level, which is conducive to the stability of the structure. The prepared material has a high charge and discharge capacity, excellent cycle stability, and good rate performance.

The invention discloses a glass plate and glass paper clamping device and method. The glass plate and glass paper clamping device comprises a sucking disc frame, a plate lowering device and a paper taking device; the plate lowering device comprises a first sucking disc, a second sucking disc rod and a first vacuum generator; the paper taking device comprises a second sucking disc, a paper taking air cylinder, a rotary air cylinder, a rotary arm, a second sucking disc rod, a second vacuum generator and a paper taking support rod; a glass plate is adsorbed through the first sucking disc and thefirst vacuum generator to carry the glass plate down from a transfer buggy so as to realize the plate lowering function; the second sucking disc and the second vacuum generator adsorb glass paper to realize the paper taking function; the paper taking air cylinder, the rotary air cylinder and the rotary arm provide dependence when the second sucking disc and the second vacuum generator adsorb glasspaper to combine the plate lowering and paper taking functions on the same rack, so that the occupied area is reduced; the structure is simple; and the vacuum generators and the sucking discs are cooperated to establish vacuum, so that the adsorption capacity of the sucking discs to the glass plate and the glass paper is improved during the carrying process to improve the safety.
