Technical Field

[0001] The utility model belongs to the technical field of AGV trolleys, in particular to a laser radar navigation device of an AGV trolley. Background Art

[0002] Plate rollers are also called steel rollers, which are divided into hollow rollers and solid rollers, shaft rollers and non-shaft rollers. They are generally used for plate making. The surface of the roller is copper-plated, and the pattern is engraved by the gravure electronic engraving machine, and then plated with a layer of chrome. After it is finished, it is delivered to the printing factory and is often used for printing plastic packaging. During the plate roller processing, it is automatically transported by the AGV car, which is efficient and convenient.

[0003] The current automatic navigation technology of AGV carts mainly relies on magnetic stripe navigation and laser navigation. The laser navigation device currently used in AGV carts has a complex angle adjustment structure during use, and the navigation device as a whole lacks a protective structure, which makes the navigation components in the non-working state easily damaged by collision.

[0004] To this end, we provide a laser radar navigation device for the AGV car to solve the above problems. Utility Model Content

[0025] See also Figure 1-4 The utility model is a laser radar navigation device for an AGV vehicle, comprising a laser navigation component 1, wherein the laser navigation component 1 comprises a protective cover 11, a back plate 19 fixed to the back of the protective cover 11, a cylinder 110 fixed to the top of the back plate 19, a support plate 12 connected to the telescopic end of the cylinder 110, a motor 14 fixed to the middle position of the upper side of the support plate 12, a bracket 15 connected to the output shaft of the motor 14, a motor 2 17 fixed to the side of the bracket 15, a positioning ring 16 connected to the output shaft of the motor 2 17, and a laser navigation body 18 threadedly adapted to be installed inside the positioning ring 16.

[0026] Specifically, in the laser radar navigation device of the AGV car proposed in the present application, the accurate navigation of the AGV car is realized by setting the laser navigation component 1, and the bracket 15 and the laser navigation body 18 fixed on the bracket 15 can be rotated by the drive of the motor 14 to realize the all-round scanning of the environment; the bracket 15, as the supporting structure of the laser navigation body 18, not only connects the motor 14 and the motor 2 17, but also ensures the stability of the laser navigation body 18 during the rotation process; the motor 2 17 is installed on the side of the bracket 15, and its output shaft is connected to the positioning ring 16; through the fine adjustment of the motor 2 17, the laser navigation body 18 can be fine-tuned on the horizontal plane, thereby further improving the accuracy of navigation; the positioning ring 16 is a precision component with threads inside for installing the laser navigation body 18. Through the drive of the motor 2 17, the positioning ring 16 can accurately adjust the position and angle of the laser navigation body 18. The laser navigation body 18 is the core part of the whole device, which senses the surrounding environment by emitting a laser beam and receiving the reflected signal, thereby calculating the position of the AGV car.

[0027] The back plate 19 is fixed with a guide rod 111 on its edge, and the guide rod 111 is matched with a guide seat 13, and the guide seat 13 is fixed to the lower side edge of the support plate 12, and the guide seat 13 and the outer side of the support plate 12 and the inner side of the protective cover 11 are in contact with each other;

[0028] The cooperation between the guide rod 111 and the guide seat 13 can effectively prevent the support plate 12 from deflecting or shaking during the movement, thereby ensuring the accuracy and stability of the positioning of the laser navigation body 18. The guide seat 13 is designed with a groove or hole matching the guide rod 111, so that the support plate 12 can slide back and forth along the guide rod 111. The outer side of the guide seat 13 and the support plate 12 fits with the inner side of the protective cover 11, further increasing the structural stability of the entire laser navigation assembly 1, and can effectively reduce the impact of vibration and impact generated during the movement of the AGV trolley on the laser navigation assembly 1, thereby improving its working stability and reliability.

[0029] Furthermore, an axial hole 112 is opened in the middle position of the upper side surface of the support plate 12, and the axial hole 112 cooperates with the output shaft of motor 14; a transmission seat 114 is provided on one side of the bracket 15, and a bearing seat 113 is provided on the other side of the bracket 15, the transmission seat 114 cooperates with the output shaft of motor 2 17, and the built-in shaft of the bearing seat 113 cooperates with the positioning ring 16; the motor 14 and the motor 2 17 have built-in encoders; the positioning ring 16 is located between the brackets 15, and the internal thread of the positioning ring 16 is adapted to the laser navigation body 18.

[0030] In the above embodiment, the function of the protective cover 11 is to protect the internal laser navigation assembly 1 from the influence of the external environment, such as dust, water vapor, etc. The back plate 19 is fixed to the back of the protective cover 11 to provide stable support for the entire laser navigation assembly 1;

[0031] The cylinder 110 is responsible for adjusting the position of the laser navigation body 18. Through the extension and retraction of the cylinder 110, the extension end drives the laser navigation body 18 to reach a suitable working position through the support plate 12. It is also used for the storage and protection of the laser navigation body 18. The motor 14 and the motor 2 17 are responsible for driving the rotation of the bracket 15 and the positioning ring 16 respectively. The transmission seat 114 and the bearing seat 113 on the bracket 15 ensure the stable connection between the output shaft of the motor 2 17 and the positioning ring 16; the positioning ring 16 is located between the brackets 15, and its internal thread is adapted to the laser navigation body 18, ensuring that the laser navigation body 18 can be stably and accurately installed on the positioning ring 16, which not only improves the convenience of installation, but also ensures the accuracy of navigation.

[0032] In addition, motor 1 14 and motor 2 17 have built-in encoders that can monitor and control the rotation angle and speed of the motors in real time, thereby achieving precise control of the angle of the laser navigation body 18; during the driving of the AGV, the laser navigation body 18 will emit a laser beam, and sense the surrounding environment and calculate the distance by receiving the reflected light beam. At the same time, combined with map information and path planning algorithms, the AGV is controlled to travel along a predetermined path to achieve automated navigation (the principle of this navigation technology is currently a relatively mature technology and is not described in further detail here).
