[0002] Palletizing robots are the product of the organic combination of machinery and computer programs, providing higher production efficiency for modern production. They have the characteristics of saving labor, saving space, flexible and precise operation, fast and efficient, high stability, and high operating efficiency. Palletizing robots are widely used in the palletizing industry, greatly saving labor and space. The installation space of the coordinate robot using patented technology of the palletizing robot system is flexible and compact, and it can build an efficient and energy-saving fully automatic block forming machine production line within a small footprint.

[0003] The palletizing robot mainly drives two clamping plates through cylinders or servo motors to clamp the boxes on the assembly line and stack them on the receiving table. When the palletizing robot places the box on the pile of other boxes, the box will not be tightly attached to other boxes. The main reason is that the two clamping plates clamping the box itself have thickness. Although the gap between the boxes is not large, when the boxes are piled high, this gap will cause the stacked boxes to collapse easily. In order to solve this technical problem, the utility model proposes a box palletizing robot. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, through the cooperation among the servo motor, the clamping plate, the buffer plate, the cylinder and the push plate, the servo motor can drive the clamping plate and the buffer plate to move relative to each other, so that the box can be clamped, and a layer of rubber is arranged on the surface of the buffer plate. The main material of the rubber is red butyl rubber or hydrogenated nitrile rubber, so that it can have excellent friction and wear properties. Then, when the clamping plate is slightly loosened, the gravity of the box is less than the friction between the buffer plate and the box. When the box moves to the box stack, the lower side of the box is first attached to the other On the box, the servo motor then reverses to loosen the clamping plate slightly, and then turns on the cylinder, which can push the push plate, so that the push plate can move downward to push the box downward, and then break away from the clamping of the buffer plate, so that the box can be attached to the outside of other boxes and fall naturally and slowly. Since the clamping plate is not inserted between the boxes, the width of the gap between the boxes can be greatly reduced to close to zero, so that the stacked boxes are close to each other, thereby solving the problem that the boxes are prone to collapse when they are stacked to a certain height due to gaps.

[0014] In the utility model, through the cooperation between the spring, the directional rod, the flange, the protective shell and the buffer plate, the spring can always push the flange with the protective shell as the reference point, so that the flange can push the buffer plate through the directional rod, forcing the buffer plate to maintain a mutual contact relationship with the box body when the clamping plate is loose.
