[0043] like Figure 1 As shown, this embodiment provides a carton opener for opening sheet-like cardboard boxes. The carton opener includes a multi-axis robot arm 200 and a carton opener 100. The carton opener 100 is installed at the output end of the multi-axis robot arm 200. The multi-axis robot arm 200 is used to change the posture of the carton opener 100.

[0044] like Figure 1-Figure 3 As shown, the unpacking device 100 includes a connecting frame 60 and a fixed mounting plate 10 and a folding cover plate 20 that are rotatably connected. A first suction cup 30 is installed on one side of the fixed mounting plate 10, and a flip driving member 50 and a connecting frame 60 are installed on the other side of the fixed mounting plate 10. The folding cover plate 20 is set as a hollow structure, and a second suction cup 40 is installed on the hollow structure. The output end of the flip driving member 50 is rotatably connected to the folding cover plate 20, and the flip driving member 50 is used to drive the folding cover plate 20 to rotate relative to the fixed mounting plate 10. The first suction cup 30 and the second suction cup 40 are respectively used to adsorb the adjacent first side surface and second side surface of the carton box. The connecting frame 60 is connected to the output end of the multi-axis robot arm 200.

[0045] Specifically, the unpacking device 100 provided in this embodiment uses the first suction cup 30 and the second suction cup 40 to suck the adjacent first and second sides of the carton box, and drives the folding cover plate 20 to rotate relative to the fixed mounting plate 10 through the flip driving member 50, so that an angle is formed between the folding cover plate 20 and the fixed mounting plate 10, and the unpacking action can be completed. The unpacking action is simple. During the unpacking process, the first suction cup 30 and the second suction cup 40 respectively suck the first and second sides of the carton box. The unpacking process is stable and efficient, and can meet the unpacking requirements of carton boxes of various specifications, with high versatility, and a simple structure. The folding cover plate 20 is set as a hollow structure to reduce the action load and further improve the action speed. The unpacking machine drives the unpacking device 100 to move in space through the multi-axis mechanical arm 200 to change the latter's posture, which can meet the unpacking requirements of carton boxes of various specifications, and has high versatility.

[0046] For example, Figure 2 and Figure 3 As shown, at least two first suction cups 30 are provided to adsorb the first side surface of the paper box at multiple points to improve the stability of adsorption.

[0047] For example, Figure 3 As shown, a suction cup mounting hole 11 is provided on the fixed mounting plate 10 , and the suction cup mounting hole 11 is used for mounting and connecting the first suction cup 30 .

[0048] For example, Figure 2 and Figure 3 As shown, a suction cup adjustment hole 12 is provided on the fixed mounting plate 10, and the suction cup adjustment hole 12 is configured as a strip hole structure extending along the length direction of the fixed mounting plate 10. The first suction cup 30 can be fixed at any position on the suction cup adjustment hole 12 to flexibly adjust the adsorption point.

[0049] In this embodiment, if Figure 1-Figure 3 As shown, four first suction cups 30 are provided, and two suction cup mounting holes 11 and two suction cup adjustment holes 12 are provided on the fixed mounting plate 10. The two suction cup mounting holes 11 and the two suction cup adjustment holes 12 are distributed in a matrix, wherein two first suction cups 30 are respectively fixedly installed on the suction cup mounting holes 11 by a nut structure, and the other two first suction cups 30 are respectively fixedly installed on the two suction cup adjustment holes 12 by a nut structure.

[0050] For example, Figure 2 As shown, the box opening device 100 also includes a buffer assembly, which includes an elastic buffer 81 and a buffer stopper 82, wherein the elastic buffer 81 is installed through the fixed mounting plate 10, and the elastic buffer 81 adopts a buffer hardware dedicated to the vacuum suction cup in the prior art.

The buffer stopper 82 is fixedly installed on the fixed mounting plate 10, and the buffer stopper 82 is located between the fixed mounting plate 10 and the buffer head. The buffer stopper 82 is used to limit the maximum retraction distance of the elastic buffer 81.

[0051] For example, Figure 2 As shown, a plurality of first weight-reducing holes 13 are provided on the fixed mounting plate 10 to reduce the weight of the fixed mounting plate 10 and improve the flexibility of the box opener.

[0052] For example, Figure 2 and Figure 3 As shown, a plurality of second weight-reducing holes 61 are provided on the connecting frame 60 to reduce the weight of the connecting frame 60 and improve the flexibility of the box opener.

[0053] For example, Figure 2 and Figure 3As shown, the folding cover plate 20 includes a connecting portion 21 and a mounting portion 22. The connecting portion 21 is rotatably connected to the fixed mounting plate 10. The mounting portion 22 is provided with a mounting clearance hole 221 extending in the same direction as the fixed mounting plate 10. The setting of the mounting clearance hole 221 forms the above-mentioned hollow structure, and the second suction cup 40 is penetrated through the mounting clearance hole 221.

[0054] Exemplarily, the area of ​​the mounting hole 221 accounts for more than 90% of the area of ​​the mounting portion 22 .

[0055] For example, Figure 2 and Figure 3 As shown, the length directions of the connecting portion 21 and the mounting portion 22 are perpendicular to each other, and a clearance notch 23 is provided on one side of the mounting portion 22 close to the bottom of the paper shell box, and the clearance notch 23 extends in the same direction as the mounting portion 22 and penetrates the mounting portion 22, so that the folding cover plate 20 forms an L-shaped structure. The provision of the clearance notch 23 further reduces the volume and weight of the folding cover plate 20, and further improves the flexibility of the action of the box opening device 100.

[0056] For example, Figure 2 and Figure 3 As shown, the unpacking device 100 also includes a suction cup fixing frame 41, the second suction cup 40 is fixed to the suction cup fixing frame 41, and a plurality of suction cup fastening holes 222 are symmetrically arranged on both sides of the installation clearance hole 221 in width.

[0057] For example, Figure 3 As shown, the body of the flip driving member 50 is rotatably connected to a side of the fixed mounting plate 10 that is away from the first suction cup 30, and the output end of the flip driving member 50 is rotatably connected to the folding cover plate 20. The flip driving member 50 drives the folding cover plate 20 to rotate through a linear telescopic action. Specifically, the output end of the flip driving member 50 is connected to a rotating connector 51, and a connecting rod 52 is fixed to the connecting portion 21 of the folding cover plate 20, and the connecting rod 52 is rotatably connected to the rotating connector 51.

[0058] Exemplarily, under the driving of the flip driving member 50, the angle between the fixed mounting plate 10 and the folding cover plate 20 varies in the range of 90°-180°. When the flip driving member 50 is extended to the extreme position, the angle between the fixed mounting plate 10 and the folding cover plate 20 is 90°; when the flip driving member 50 is retracted to the extreme position, the angle between the fixed mounting plate 10 and the folding cover plate 20 is 180°.

[0059] Exemplarily, the flip driving member 50 can be a linear driving member such as a linear cylinder, an electric push rod, etc.

[0060] For example, Figure 2 and Figure 3 As shown, the fixed mounting plate 10 and the folding cover plate 20 are rotationally connected via a folding cover shaft 90, both ends of the folding cover shaft 90 are rotationally connected to the fixed mounting plate 10, and the connecting portion 21 of the folding cover plate 20 is fixed to the periphery of the folding cover shaft 90 by fastening screws.

[0061] For example, Figure 3 As shown, the unpacking device 100 also includes a first vacuum generator 71 and a second vacuum generator 72. The first vacuum generator 71 and the second vacuum generator 72 are both fixed to the connecting frame 60. The first vacuum generator 71 is connected to the first suction cup 30 through an air pipe to provide suction for the first suction cup 30; the second vacuum generator 72 is connected to the second suction cup 40 through an air pipe to provide suction for the second suction cup 40.
