Description

Technical Field

[0001] The utility model relates to the technical field of AGV chassis auxiliary equipment, in particular to an AGV driving chassis. Background Art

[0002] There are many ways to drive and navigate AGVs, among which magnetic stripe navigation is considered to be a very mature technology. It mainly obtains the position deviation between the vehicle itself and the target tracking path by measuring the magnetic field signal on the path, thereby realizing the control and navigation of the vehicle. Magnetic stripe navigation has high measurement accuracy and good repeatability. Magnetic navigation is not easily affected by light changes, etc. During operation, the magnetic sensing system has high reliability and robustness. Once the magnetic stripe is laid, the maintenance cost is very low, the service life is long, and it is easy to add and change the path.

[0003] However, magnetic strip navigation also has corresponding disadvantages. For example, the magnetic strip will attract metal substances, causing the metal substances to be stirred into the AGV chassis, causing the AGV chassis to malfunction. However, the existing AGV trolleys used in magnetic strip navigation do not have corresponding measures to prevent metal substances from entering. Therefore, those skilled in the art have proposed a solution for AGV driving chassis. Utility Model Content

[0029] The front magnetic shell 2 includes an arched shell 21, 10-15 electromagnets 23 equidistantly fixed in the inner cavity of the arched shell 21, and a groove 22 arranged on the bottom surface of the arched shell 21, and the magnetic end of the electromagnet 23 is in contact with the bottom surface of the inner cavity of the arched shell 21; the side cleaning component 3 includes a rectangular frame 31, a dual-axis servo motor 32 fixedly connected to the top surface of the inner cavity of the rectangular frame 31, and two transmission shafts 34 fixedly connected to the front and rear output ends of the dual-axis servo motor 32 through a coupling, and two wool rollers 33 fixedly connected to the outer ring of the transmission shaft 34.

[0030] The rear surface of the arch shell 21 is fixed to the front surface of the vehicle body base 11 by 8-12 screws, and the interior of the arch shell 21 is hollow. Several plastic bristles are fixed to the front side of the bottom surface of the arch shell 21 by adhesive to clean the iron filings on the ground navigation magnetic strip. The arch shell 21 is made of plastic material, and the groove 22 is made of cast iron, wherein the bottom surface of the arch shell 21 is provided with a rectangular through hole for the groove 22 to be embedded.

[0031] The rectangular frames 31 are all arranged in a left-right mirror symmetric manner with the central axis of the vehicle body base 11 as the base point, and the side surface and the bottom surface of the rectangular frame 31 away from the vehicle body base 11 are both opened. The end of the transmission shaft 34 away from the dual-axis servo motor 32 is rotatably connected to the front and rear side walls of the inner cavity of the rectangular frame 31. The outer ring surface of the wool roller 33 is in contact with the ground, and is used to sweep away the iron filings swept to both sides by the plastic bristles on the front side of the arched shell 21.

The energized electromagnet 23 will generate magnetic force and transmit it to the groove 22. After the AGV chassis mechanism 1 passes through the magnetic strip, the strong magnetic force of the electromagnet 23 will collect the iron filings or metal materials originally adsorbed on the magnetic strip guide rail into the groove 22. At the same time, the iron filings scattered around the magnetic strip are swept away by the rotating wool roller 33, reducing the amount of iron filings entering the interior of the AGV chassis mechanism 1, thereby protecting the driving components of the AGV chassis mechanism 1.
