Description

Technical Field

[0001] The present invention relates to the technical field of workshop transfer, and specifically to a laser-guided vehicle for workshop transfer. Background Art

[0002] In the context of the intelligent and automated upgrading of modern manufacturing, the laser-guided vehicle (AGV) for workshop transfer, as the core equipment for material handling, its performance directly affects production efficiency and stability. However, the traditional laser-guided vehicle for workshop transfer exposes the following technical bottlenecks in practical applications.

[0003] However, the traditional laser-guided vehicle for workshop transfer has the following disadvantages:

[0004] (1) When it is necessary to adjust the vehicle body height to adapt to different working scenarios (such as crossing a gully or passing through a slope), the traditional guided vehicle lacks a convenient height adjustment mechanism and requires manual assistance or relies on external equipment. The operation is cumbersome and the flexibility is poor, making it difficult to meet the diverse transfer requirements of the workshop.

[0005] (2) Most of the existing heat dissipation structures of the guided vehicle are fixed designs. After long-term use, the heat dissipation net is prone to dust accumulation and blockage, resulting in a decrease in the internal heat dissipation efficiency of the equipment. Moreover, disassembling, cleaning, or replacing the heat dissipation net requires tools and takes a long time, affecting the continuous operation efficiency of the equipment.

[0046] In the present invention, the working steps of the device are as follows:

[0047] S1: First, when in use, when the vehicle body 1 of the guiding vehicle passes through the uneven ground in the workshop or the connection at the loading and unloading platform, the servo motor 401 is started, so as to drive the first rotating rod 306 to rotate through the transmission assembly 4, and then drive the lifting rod 305 to rise;

[0048] S2: Then, when the AGV body 1 jolts, the buffer rod 301 slides on the second plug rod 302 and compresses the buffer spring 303, thereby converting the impact force into the elastic performance of the buffer spring 303 itself, thus preventing the internal electronic components of the AGV body 1 from being damaged due to jolts and increasing its own service life.

[0049] S3: Finally, after the power is turned on, sensors such as lidar, inclinometer sensor, and encoder start self-checking, and feedback their own status information to the PLC. The PLC initializes the internal program, loads the preset map data or enters the map construction preparation state. The lidar continuously emits laser beams, receives the reflected light and calculates the distance to surrounding objects, constructs a two-dimensional or three-dimensional environmental map, and uses the SLAM algorithm to combine the wheel rotation information provided by the encoder to determine the position and attitude of the AGV in the map. Input commands such as the target position through the human-machine interface. The PLC calculates the optimal driving path according to the current position and the target position, combined with the map information, using the path planning algorithm. According to the path planning result, the PLC sends control commands to the servo driver to adjust the speed and steering of the servo motor, and drives the AGV to travel according to the planned path. During the driving process, continuously receive the sensor feedback information. If the lidar detects an obstacle, immediately re-plan the path or decelerate and stop to avoid the obstacle; when the inclinometer sensor detects that the vehicle body tilts beyond the threshold, adjust the power distribution of the drive wheels to maintain the balance of the vehicle body.
