Abstract

The invention provides a laser raster locating system for a rail mobile device and relates to a laser locating system. The laser raster locating system for the rail mobile device comprises a movement guide rail (1), the mobile device (2), a laser emitting and receiving module (3) and a locating raster bar (4). The movement guide rail (1) is used for offering movement restraint and a movement trail of the mobile device; the bottom of the mobile device (2) is installed on the movement guide rail and the mobile device (2) moves laterally along the movement guide rail; the laser emitting and receiving module (3) is fixed to the mobile device (2) and used for emitting lasers and receiving reflected laser signals; the locating raster bar (4) is installed on a fixed rack (5) and used for providing the reflected laser signals with different intensities and modes, wherein the fixed rack (5) is used for containing an object to be located. According to the laser raster locating system for the rail mobile device, the locating error is smaller than 2mm, the locating accuracy and the locating reliability are high, the manufacturing cost is low, and the laser raster locating system for the rail mobile device is particularly suitable for the accurate location of the rail mobile device.

Description

technical field [0001] The invention relates to a laser positioning system, in particular to a laser grating precise positioning system for rail moving equipment based on the principles of laser total reflection and diffuse reflection. Background technique [0002] With the development of science and technology and society, a large number of smart mobile devices are emerging, such as smart storage systems, smart library systems and book ATM machine systems. In these systems, the precise positioning technology of manipulators, robotic arms, and stackers is very important, and most of the existing positioning technologies use methods such as laser distance measurement, motion trajectory calculation, and barcode scanning. These existing technologies have the disadvantages of high price, poor positioning accuracy and poor reliability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a laser grating positioning system...
