Positioning device for lifting equipment of AGV trolley

Abstract

The invention discloses a positioning device for lifting equipment of an AGV trolley. The positioning device comprises the lifting equipment, a positioning mechanism and a PLC. The lifting equipment comprises a lifting well, a car, a hoisting assembly and a lifting driving mechanism, the side wall of the designated position of the lifting well is provided with a supporting base, the positioning mechanism comprises a cantilever and a driving assembly, the cantilever can be located in the internal area at the outer bottom of the car when the car moves, the cantilever can be located in the external area at the outer bottom of the car when the car stops at the designated position, the cantilever can be in abutting connection with the supporting base, the driving assembly can drive the cantilever to move between the internal area at the outer bottom of the car and the external area at the outer bottom of the car, the lifting assembly is in a loosened state when the cantilever is in abuttingconnection with the supporting base, and the lifting driving mechanism and the driving assembly are both electrically connected with the PLC. According to the positioning device for the lifting equipment of the AGV trolley, when the AGV trolley enters or exits from the car, the car is prevented from sinking and rebounding, and walking requirements on the AGV trolley are met.

Description

technical field [0001] The invention relates to the technical field of AGV trolleys, in particular to a positioning device for lifting equipment of AGV trolleys. Background technique [0002] AGV is the English abbreviation of Automated Guided Vehicle. It refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along the specified 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. Generally, the computer can be used to control its travel route and behavior, or use the electromagnetic track (electromagnetic path-following system) to set up its travel route. The electromagnetic track is pasted on the floor, and the unmanned van follows the information brought by the electromagnetic track. To move and act. [0003] AGV trolleys have been widely used in many automation industr...

AI Technical Summary

Problems solved by technology

There is a certain height difference between the car of the traditional lifting platform or the elevator and the ground. At the same time, when the AGV trolley enters / exits the car, the car will slightly sink or rebound due to the change of the car load. The deviations are superimposed, far exceeding ±10mm, which cannot meet the requirements for the AGV car to enter and exit the car, and even damage the sensor at the bottom of the AGV car. This is the bottleneck of the development of the automatic elevation of the AGV car facade.
