Description

Technical Field

[0001] The utility model relates to the technical field of transport robots, in particular to a sensor installation, positioning and calibration device for a transport robot. Background Art

[0002] With the continuous increase in labor costs, the development and demand for unmanned logistics, and the growing demand for AGVs, the market for converting existing vehicle bodies into AGVs has also been driven. Among these, stacker forklifts are more common in warehousing and logistics. However, due to the large body of this type of forklift and the basic errors in the body assembly and installation process by the vehicle manufacturer, AGV conversion manufacturers inevitably encounter errors in sensor installation and positioning calibration when converting ordinary stacker forklifts into AGVs. Especially in the context of the current AGV navigation accuracy reaching 10mm, the precise positioning and installation of related sensor devices (cameras, lidar, etc.) is particularly important when converting AGV bodies. The ability to align and calibrate the installation, build the positioning map of the body, and control the motion of the body steering wheel are extremely important. At the same time, accurate calibration installation can also reduce many errors caused by the horizontal deviation between the moving steering wheel and the sensor during subsequent body debugging. During the modification of multiple vehicles, each vehicle may have different degrees of sensor installation position deviation due to differences in its assembly process, brand, and model. Therefore, it is extremely important to design a device that can calibrate the horizontal and vertical alignment of the steering wheel center and the installed sensor. Utility Model Content
