[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 In this embodiment, a clamping mechanism based on a robot palletizer includes a base 1, a fixing rod 2 is fixedly installed on the top of the base 1, a reinforcing rod 3 is movably installed on the outer surface of the fixing rod 2, a cross bar 4 is movably installed on one end of the reinforcing rod 3, a clamping mechanism 5 is installed on one end of the cross bar 4 through a driving motor, and an anti-falling component 6 is installed on the surface of the clamping mechanism 5.

[0023] It should be noted that palletizing technology is an emerging technology in the field of logistics automation technology. Palletizing is to stack materials into stacks according to a certain pattern based on the idea of ​​integrated unitization, so as to realize logistics activities such as material handling, loading and unloading, transportation, and storage. The clamping mechanism 5 and the anti-drop assembly 6 set above can cooperate to form a clamping device of the palletizer, and the device has the advantage of preventing objects from falling off.

[0024] The holding mechanism 5 includes a top plate 501, on which the top plate 501 is fixedly mounted at the output shaft of the driving motor, a dual-axis motor 502 is fixedly mounted inside the top plate 501, threaded rods 503 are fixedly mounted at the output shafts of the dual-axis motor 502, threaded cylinders 504 are threadedly connected to the outer surfaces of the two threaded rods 503, and limit rings 505 are fixedly mounted on the outer surfaces of the two threaded cylinders 504, and two clamping plates 506 are slidably mounted on the bottom of the top plate 501. In the process of clamping an object, the dual-axis motor 502 is turned on to drive the two threaded rods 503 to rotate, and the rotation of the two threaded rods 503 drives the threaded cylinder 504 to move, and the threaded cylinder 504 drives the limit ring 505 to slide, thereby driving the two clamping plates 506 to approach the opposite side to clamp the material.

[0025] Two slide grooves are provided on the bottom outer surface of the top plate 501, and the bottoms of the two limit rings 505 are fixedly connected to the top of the clamping plate 506 through a connecting rod. Rubber pads are fixedly installed on the opposite sides of the two clamping plates 506. During the movement, the two limit rings 505 drive the clamping plates 506 to move through the connecting rod, so that the connecting rod slides in the slide groove, and the rubber pads can protect the surface of the object.

[0026] The anti-falling component 6 includes two fixed blocks 601, and the front and rear sides of the top plate 501 are fixedly installed with fixed blocks 601, and the outer surfaces of the two fixed blocks 601 are rotatably installed with support plates 602, and the bottom outer surface of the top plate 501 is fixedly installed with a dual-axis motor 603, and the output shafts of the dual-axis motor 603 are fixedly installed with screw rods 604, and the outer surfaces of the two screw rods 604 are threadedly connected with movable blocks 605, and the outer surfaces of the two movable blocks 605 are movably installed with traction rods 606. After the object is clamped, the dual-axis motor 603 is turned on at the same time. The turning on of the dual-axis motor 603 drives the two support plates 602 to approach each other, and the two support plates 602 support the bottom of the object to avoid damage to the object due to slipping during transportation.

[0027] The two support plates 602 are both L-shaped, and both support plates 602 are lower than the clamping plate 506. The two L-shaped support plates 602 can support the bottom of the object to prevent the object from falling.

[0028] When implementing, follow these steps:

[0029] 1) When in use, the device is powered on, and the two clamping plates 506 are driven to move to opposite sides by turning on the dual-axis motor 1 502;

[0030] 2) Then two clamping plates 506 clamp the object;

[0031] 3) Turn on the second dual-axis motor 603 at the same time, and the turning on of the second dual-axis motor 603 pulls the support plate 602 closer;

[0032] 4) Finally, the two support plates 602 support the bottom of the object.

[0033] In summary, the clamping mechanism based on the robot palletizer is configured with the top plate 501, the dual-axis motor 502, the threaded rod 503, the threaded cylinder 504, the limit ring 505 and the clamping plate 506. In the process of clamping the object, the dual-axis motor 502 is turned on to drive the two clamping plates 506 to move to the opposite side, so that the object is clamped by the two clamping plates 506 to achieve the clamping purpose.

[0034] In addition, by setting the coordination among the fixed block 601, the support plate 602, the dual-axis motor 603, the screw rod 604, the movable block 605 and the traction rod 606, after the object is clamped, the dual-axis motor 603 is turned on at the same time, and the turning on of the dual-axis motor 603 drives the two screw rods 604 to rotate, and the rotation of the two screw rods 604 simultaneously drives the movable block 605 to move to the opposite side, and the support plates 602 are pulled closer by the traction rod 606, so that the two support plates 602 support the bottom of the object to avoid damage to the object due to slipping during transportation, thereby ensuring that the material is clamped without causing damage to the material.
