Project background: Before, forklift or truck was used on site for material transfer and transportation, and all processes were assembled in one station. When this station was completed, operators were transferred to the next station for operation, resulting in personnel concentration and low working efficiency.

Solution: Through efficiency calculation, the operation process is divided into assembly line operation, divided into 14 stations, the personnel for post operation. 4 sets of 6.5*1.6 meters bearing 3 tons and 1 set of 1 ton omnidirectional knapsack AGV are used to carry out the handling work of the refrigerator. Through traffic control coordination, the safety problem of multiple AGVs running in the same area is solved, the established route of each AGV is set, and after manual operation of the call system, it is uploaded to the dispatching system. The dispatching system dispatches the AGVs for operation according to the task assignment, and realizes the seamless process turnover of multiple AGVs in the same area from station 1 to station 14.

When the goods are deflecting, it can be corrected automatically. Two limiting tracks are added on the contact surface between the horse stool and the AGV on both sides of the cargo space, and fixed regulating wheels are added on both sides of the AGV body. When the AGV reaches the station, the regulating wheels of the vehicle body enter the preset limiting track, correct the Angle of the vehicle body, and keep running without Angle deviation to place the goods at the anchoring point to complete the task.
