After the AGV cart moves to the front side of the substrate 1, the infrared sensors 18 can be started simultaneously. Under the action of the infrared sensors 18, the limiting strip plate 8 can sense whether it corresponds to the front side of the movable strip plate 9, and then the infrared sensors 18 send commands to the servo motor 12 to control the first L-shaped support plate 3 and the second L-shaped support plate 4 to move, so that the limiting strip plate 8 can be moved more precisely to the interlaced position with the movable strip plate 9, and the first L-shaped support plate 3 and the second L-shaped support plate 4 can be precisely positioned and adjusted, without the need for the AGV cart to perform fine-tuning of the docking position independently, effectively reducing the manufacturing and programming costs of the AGV cart.
[0027] The utility model can place the heavy object bearing plate 5 on the top of the AGV cart for transportation. After the AGV cart moves to the front side of the substrate 1, the infrared sensor 18 can be started simultaneously. Under the action of the infrared sensor 18, the limit strip plate 8 can sense whether it corresponds to the front side of the movable strip plate 9.

The heavy object bearing plate 5 is braked through the movable strip plate 9. When the AGV cart transports the heavy object bearing plate 5 to the front sides of the first L-shaped support plate 3 and the second L-shaped support plate 4, the AGV cart pushes the heavy object bearing plate 5 to the tops of the first L-shaped support plate 3 and the second L-shaped support plate 4, and the limit strip plate 8 at the bottom of the heavy object bearing plate 5 is embedded between the limit strip plates 8 in the installation notches 7 of the first L-shaped support plate 3 and the second L-shaped support plate 4, so that the heavy object bearing plate 5 can be transferred to the tops of the first L-shaped support plate 3 and the second L-shaped support plate 4 for placement. By starting the servo motor 12, the output shaft of the servo motor 12 drives the lead screw 13 to rotate, so that the lead screw 13 and the moving block 15 on the outer side of the guide rod 14 drive the first L-shaped support plate 3 and the second L-shaped support plate 4 to move and adjust. The distance between the first L-shaped support plate 3 and the second L-shaped support plate 4 can be flexibly adjusted according to the length of the heavy object bearing plate 5. After the movable strip plate 9 and the limit strip plate 8 are staggeredly engaged, the limit screw 17 can be screwed and installed on the outer sides of the first L-shaped support plate 3 and the second L-shaped support plate 4 respectively, so that the limit screw 17 sequentially passes through the threaded holes 16 on the movable strip plate 9 and the limit strip plate 8 and is threadedly connected and fixed. Under the action of the limit screw 17, the situation that the heavy object bearing plate 5 falls off accidentally after being placed on the tops of the first L-shaped support plate 3 and the second L-shaped support plate 4 can be avoided.
