Full-linkage lifting tray calibration device and method

Abstract

The invention discloses a full-linkage lifting tray calibration device, which comprises a lower bottom plate, an upper bottom plate, a first side push plate, a second side push plate, a limiting switch base, an in-seat switch and a driving system; a plurality of vertical electric push rods and nylon stand columns are arranged on the lower bottom plate, and the upper bottom plate is arranged at theupper end of the lower bottom plate and is supported by the vertical electric push rods to ascend and descend; guide rails are respectively arranged in parallel in four directions of the upper bottomplate; sliding blocks are arranged on the guide rails in a sliding manner; a first connecting plate is arranged on the back surface of the first side push plate; a second connecting plate is arrangedon the back of the second side push plate; the limit switch base is connected with the upper bottom plate, the on-seat switch is connected with the upper bottom plate, and the driving system is fixedly connected with the center of the lower end of the upper bottom plate. Full-linkage inward movement of the first side push plate and the second side push plate is achieved, manual placement errors,tray damage and potential safety hazards are avoided, and the calibration efficiency is improved; the service life of the tray is ensured; the limiting range of the tray is expanded; the limiting precision adjustment is achieved; and the precision butt joint requirements of other robots are met.

Description

technical field [0001] The invention belongs to the technical field of industrial vehicles with automatic guidance function, in particular, the invention relates to a fully linked lifting tray calibration device and method. Background technique [0002] AGV refers to a transport vehicle equipped with automatic navigation devices such as electromagnetic or optical, capable of driving along a prescribed navigation path, with safety protection and various transfer functions. A truck that does not require a driver in industrial applications is powered by a rechargeable battery. Generally, the computer can be used to control its travel path and behavior, or the electromagnetic track can be used to set up its travel path. The electromagnetic track is pasted on the floor, and the unmanned van relies on the information brought by the electromagnetic track to move and move. [0003] AGV is a new technology product, which has high requirements on safety and must obtain the status of ...

AI Technical Summary

Problems solved by technology

[0005] 2. Consistency and precision differences of multiple AGV forklifts;

[0006] 3. Accumulated error of repeated pallet handling;

[0007] 4. Abnormal displacement of the tray;

[0014] 1. High requirements for manual placement and reduced placement efficiency

[0015] 2. Damage the tray, because it is a mechanical hard impact, the contact sound is loud, the tray is damaged, and the life is reduced;

[0016] 3. Damage to the limit structure. Due to mechanical collision, the limit structure is repeatedly scratched, and damage and paint peeling will occur to varying degrees several times;

[0017] 4. The limit range is limited, because the height of the pallet is fixed and the guiding angle of the pallet is limited, so the guiding range is limited;

[0018] 5. The limit accuracy is limited because the limit structure cannot be moved. In order to ensure that the pallet can be taken out smoothly, the limit structure has a certain gap with the pallet in theory;

[0019] 6. There are potential safety hazards. First: Once the vehicle exceeds the limit precision in the way of falling, the goods cannot slide down, and the pallet is stuck on the limit structure, which can easily cause potential safety hazards. Second: Once the vehicle enters the way beyond the limit precision, The pallet will hit the limit structure, the pallet will be damaged, and the material will be damaged
