A pallet calibration device and method

Abstract

The invention discloses a pallet calibration device and method, which comprises a base plate 1, a base plate 2, a side push plate, a forward push plate, a limit switch seat and an on-seat switch; There is a slider 1, an electric push rod 1 is arranged in the middle of the bottom plate 1, and the push rod end of the electric push rod 1 is hinged to the middle of the side push plate; the two sides of the bottom plate 2 are parallel to the guide rail 2, and the slide block 2 is installed on the guide rail 2. There is an electric push rod 2 in the middle of the bottom plate 2, and the push rod end of the electric push rod 2 is hinged with the middle of the forward push plate; the side push plate is provided with the connecting plate 1; the forward push plate is provided with the connecting plate 2; the limit switch seat and the base plate One connection, the limit switch seat is connected to the bottom plate two, and the seat switch is connected to the bottom plate one, avoiding manual placement errors, damage to the tray, potential safety hazards, and improving calibration efficiency; ensuring the service life of the tray; increasing the limit range of the tray to adapt Pallets of different sizes; realize limit precision adjustment; meet the precision docking requirements of other robots.

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 pallet 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 the vehicle at all ...

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
