Description

Linear guide rail type AGV multimodal positioning mechanical device Technical Field

[0001] This utility model belongs to the technical field of AGV multimodal positioning mechanical devices, specifically relating to a linear guide rail type AGV multimodal positioning mechanical device. Background Technology

[0002] AGV, or Automated Guided Vehicle, refers to a transport vehicle equipped with electromagnetic or optical automatic guidance devices. It can travel along a prescribed guidance path and has safety protection and various transfer functions. AGVs belong to the category of wheeled mobile robots. The linear guide AGV multimodal positioning mechanical device is an automated guided vehicle positioning system specifically designed for high-precision linear motion scenarios. It combines the constraint advantages of mechanical guide rails with the positioning capabilities of multiple sensors to achieve nanometer-level repeatability positioning accuracy.

[0003] Currently, existing linear guide AGV multimodal positioning devices do not have an automatic lubrication function, which means that the lubrication needs to be added manually during long-term operation, causing time and labor costs for workers. Therefore, it is necessary to design a linear guide AGV multimodal positioning device. Summary of the Invention

[0004] The purpose of this invention is to provide a linear guide rail type AGV multimodal positioning mechanical device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

An oil outlet pipe is connected to the bottom of the inner side of the lubricating oil tank, and a pressure permeation membrane is provided at the end of the oil outlet pipe. Under pressure, lubricating oil will leak out, preventing automatic leakage of lubricating oil at the end of the oil outlet pipe.

[0008] The wiping and cleaning assembly includes a housing, the top of which is fixedly connected to the bottom of the mounting platform. A second telescopic cylinder is fixedly connected to the top of the inner wall of the housing. A movable plate is fixedly connected to the bottom of the second telescopic cylinder.

[0014] As a preferred embodiment of this utility model, through grooves are provided on both sides of the bottom of the box, and the diameter of the inner cavity of the through groove is larger than the diameter of the moving column.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting the lubrication spraying component, lubricating oil can be automatically sprayed between the linear guide rail and the drive slide mechanism, increasing the lubrication between the linear guide rail and the drive slide mechanism, reducing the wear between the linear guide rail and the drive slide mechanism, improving the running accuracy of the linear guide rail and the drive slide mechanism, achieving zero manual maintenance, and reducing the workload of workers.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Referring to Figures 1-4, this is an embodiment of the present invention. This embodiment provides a linear guide rail type AGV multimodal positioning mechanical device, including a linear guide rail 100, a drive slide mechanism 200 slidably connected to the surface of the linear guide rail 100, lubrication spraying components 210 provided on both sides of the drive slide mechanism 200, an installation platform 300 fixedly connected to the top of the drive slide mechanism 200, wiping and cleaning components 310 provided on both sides of the bottom of the installation platform 300, and an AGV vehicle body 400 adapted to be installed on the top of the installation platform 300.

[0028] The lubrication spraying assembly 210 includes a lubricating oil tank 211. The inner side of the lubricating oil tank 211 is fixedly connected to the surface of the drive slide mechanism 200. A first telescopic cylinder 214 is fixedly connected to the top of the lubricating oil tank 211. The bottom end of the first telescopic cylinder 214 extends into the inner cavity of the lubricating oil tank 211 and is fixedly connected to a piston 215. An oil outlet pipe 216 is connected to the bottom of the inner side of the lubricating oil tank 211. A pressure permeation membrane is provided at the end of the oil outlet pipe 216. Lubricating oil will leak out under pressure to prevent automatic leakage of lubricating oil at the end of the oil outlet pipe 216.

[0029] The wiping and cleaning assembly 310 includes a housing 311. The top of the housing 311 is fixedly connected to the bottom of the mounting platform 300. A second telescopic cylinder 312 is fixedly connected to the top of the inner wall of the housing 311. A moving plate 313 is fixedly connected to the bottom end of the second telescopic cylinder 312. Moving columns 314 are fixedly connected to the front and rear sides of the bottom of the moving plate 313. The bottom end of the moving column 314 extends through to the bottom of the housing 311 and is fixedly connected to a lifting plate 315. A wiping and cleaning cotton 316 is bonded to the bottom of the lifting plate 315. The bottom of the wiping and cleaning cotton 316 is in close contact with the outer surface of the linear guide rail 100.

[0030] Specifically, a limit hole is provided on the top of the linear guide 100. The linear guide 100 is I-shaped. The I-shaped cross section increases the lateral bending stiffness. The limit hole cooperates with the mechanical stop of the drive slide mechanism 200 to prevent derailment accidents in extreme cases.

[0031] Furthermore, multiple sensors are fixedly installed around the AGV body 400, including positioning sensors, environmental perception sensors, and attitude monitoring sensors. The positioning sensors improve absolute positioning accuracy, the environmental perception sensors detect nearby obstacles and prevent collisions, and the attitude monitoring sensors monitor the AGV's movement status in real time.

[0032] Preferably, the top of the outer side of the lubricating oil tank 211 is connected to a filling pipe 212, and the outer end of the filling pipe 212 is threadedly connected to a threaded cap 213. The filling pipe 212 and the threaded cap 213 facilitate the addition of lubricating oil to the lubricating oil tank 211 and extend the lubricating oil replenishment cycle, making it convenient to use.

[0033] It should be noted that the surface of piston 215 is in contact with the inner wall of lubricating oil tank 211. Piston 215 driven by first telescopic cylinder 214 achieves metered oil injection. The tight fit structure ensures that there is no leakage when the oil tank is tilted at 30 degrees (vibration test passed).

[0034] The bottom of both sides of the inner wall of the housing 311 is provided with a sliding groove, and both sides of the moving plate 313 are fixedly connected with sliders. The inner surface of the sliding groove is slidably connected to the outer surface of the slider. By setting the sliding groove and the slider, the moving plate 313 moves stably, which improves the moving stability of the moving plate 313.

[0035] Both sides of the bottom of the housing 311 are provided with through slots, and the diameter of the inner cavity of the through slot is larger than the diameter of the moving column 314;

[0036] In use, the drive slide mechanism 200 is driven by a motor to move linearly along the I-shaped linear guide rail 100. The I-shaped structure of the guide rail provides bidirectional bending stiffness. The limiting hole serves as a mechanical hard limiting reference to ensure the straightness of the movement trajectory. The lubricating oil is stored in the lubricating oil tank 211 and replenished through the filling pipe 212. The threaded cap 213 is sealed to prevent dust. The first telescopic cylinder 214 pushes the piston 215 down to squeeze the lubricating oil through the oil outlet pipe 216. The lubricating oil is sprayed onto the guide rail contact surface through the oil outlet pipe 216. The second telescopic cylinder 312 pushes the moving plate 313 down. The moving column 314 drives the lifting plate 315 and the wiping cleaning cotton 316 to contact the guide rail surface. When the drive slide mechanism 200 moves, the wiping cleaning cotton 316 wiping the guide rail surface reciprocally. When the cylinder retracts, the wiping cleaning cotton 316 is lifted away from the guide rail.

[0037] In summary, by setting up the lubrication spraying component 210, lubricating oil can be automatically sprayed between the linear guide 100 and the drive slide mechanism 200, increasing the lubrication between the linear guide 100 and the drive slide mechanism 200, reducing the wear between the linear guide 100 and the drive slide mechanism 200, improving the operating accuracy of the linear guide 100 and the drive slide mechanism 200, achieving zero manual maintenance, and reducing the workload of workers;

[0038] By setting up the wiping and cleaning component 310, the top of the linear guide 100 can be automatically wiped and cleaned, ensuring the cleanliness of the top of the linear guide 100, reducing the wear on the surface of the linear guide 100 and the inner cavity of the drive slide mechanism 200, and improving the running accuracy.
