Abstract

An AGV (Automatic Guided Vehicle) laser scanning safety protection device includes a light emitting unit, a light receiving unit, a base, a rotary platform and screws. The AGV laser scanning safety protection device is characterized in that the rotary platform is connected with the lower part of the base through the screws, the light emitting unit is connected with the upper part of the base through the screws, and the light receiving unit is connected with the light emitting unit through the screws. The light emitting unit adopts a unique laser emitting optical path system, so that the lightemitting unit is more compact and smaller, and has more concentrated laser beam energy. The scanning reference calculation formula is corrected in real time through an optical reference plane. The measurement result is more accurate. The identification rate of black objects is improved. The center of gravity of four counterweights coincides with the rotation center of a reflector plate, which ensures the rotation stability of the rotary platform. The rotary platform keeps stable in the vertical plane of the rotation axis, so that it is ensured that the emitted laser is in the same plane, the internal stress of the rotary platform is reduced, and the service life of the rotary platform is increased.

Description

technical field [0001] The invention relates to the field of laser scanning safety protection, in particular to an AGV trolley laser scanning safety protection device. Background technique [0002] AGV trolley refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions, and a transport vehicle that does not require a driver in industrial applications. The battery is its power source. [0003] The laser scanner on the AGV trolley is a safety protection device for area protection. The laser scanner measures the distance of each angle by emitting a laser beam and measuring the return time. When an object enters the set protection area, it sends a stop signal to realize the protection of personnel or equipment. The laser scanners in the prior art are often bulky and inconvenient to install and use. The laser beam emitted by th...
