[0028] The lower end of the movable mounting table 3 is threadedly connected to a threaded lead screw 12. The rear end of the threaded lead screw 12 is fixedly installed with a servo motor 13. The inner end of the movable mounting table 3 is fixedly installed with a micro motor 14. The left end of the micro motor 14 is fixedly installed with a gear 15. The front end of the gear 15 is meshed and connected to a straight plate 16. Tooth grooves 17 are equidistantly arranged at the inner end of the straight plate 16. The gear 15 is meshed and connected to the inner end of the tooth groove 17. The movable mounting table 3 is slidably arranged at the top of the main frame 5. The servo motor 13 is fixedly installed inside the main frame 5. The threaded lead screw 12 is rotatably installed inside the movable mounting table 3. Card slots 20 are arranged at the left and right ends of the straight plate 16. A clamping block 19 is slidably installed at the inner end of the card slot 20. The clamping block 19 is fixedly installed at the front end of the movable mounting table 3, which can stably and efficiently move the item to the upper part of the storage table 2 for handling without deviation and skew.

[0029] Specific working principle:

[0030] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, when using this handling robot, adjust the straight plate 16 to the upper position and adjust the movable mounting table 3 to the front side for preparation. Driven by the robotic arm 4, the storage table 2 moves to the lower front side of the goods to be handled. The air cylinder 10 drives the storage table 2 to move forward to shovel the item onto the upper surface of the storage table 2. At the same time, the micro motor 14 drives the gear 15 to rotate. The gear 15 meshes with the tooth groove 17 to drive the straight plate 16 to move downward. When the straight plate 16 moves downward, the clamping block 19 moves inside the card slot 20 to improve the stability of the straight plate 16. At this time, the straight plate 16 moves to the front side of the item. When the storage table 2 shovels up the item, the straight plate 16 can prevent the item from tipping over. Then the servo motor 13 drives the threaded lead screw 12 to rotate, thereby driving the movable mounting table 3 to move backward. When the servo motor 13 moves backward, it drives the straight plate 16 to move backward. The straight plate 16 pushes the item to move to the upper side of the storage table 2. At the same time, the electric rollers 9 on the upper side of the storage table 2 rotate to help the item quickly move to the appropriate position. Then the electric telescopic rod 6 drives the clamping plates 7 to move inward to clamp and limit the left and right sides of the item. The rubber pads 8 contact the outer surface of the item. Then the robotic arm 4 can move the item to the required position. The above completes a series of operations of this handling robot. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.
