Self-developed high-precision lifting AGV, which can be adjusted in all directions (X/Y/Z three-axis direction) to complete precise docking, and realize smart docking and automatic loading and unloading in the coating roll cutting process; In order to solve the problem that the pole piece with large coil is too heavy (about 1 ton at a time) and the magnetic stripe is easily crushed by rail navigation, the magnetic stripe navigation commonly used in the industry is upgraded to visual trackless navigation, which improves the cleanliness of the site and greatly reduces the maintenance of the navigation system in the later stage.
