The driving cylinder 6 can drive the swing arm 4 to rotate around the two rotating seats 5 to a position parallel to the fixed plate 2. At this time, the second suction nozzle 40 arranged on the swing arm 4 is in the same horizontal state as the first suction nozzle 33 on the suction nozzle fixing seat 3 to form a suction surface.

[0021] Furthermore, a first positioning threaded hole 300 is arranged on a side of the adjusting rod 30 away from the driving arm 1 , and a plurality of first adjusting bolts 310 threadably matched with the first positioning threaded hole 300 are passed through the fixing rod 31 .

[0022] Furthermore, the bottom of the adjusting rod 30 is provided with a sliding groove 301 that slidably cooperates with the fixing plate 2, the upper end of the fixing plate 2 is arranged with a second positioning threaded hole 20, and the adjusting rod 30 is penetrated by a plurality of second adjusting bolts 302 that threadably cooperate with the second positioning threaded hole 20.

[0023] Furthermore, the swing arm 4 is provided with a sliding rod 7 which is slidably matched with the left and right sides, the second suction nozzle 40 is fixed to the end of the sliding rod 7, and a cylinder-driven rotating arm 8 is provided at the bottom of the sliding rod 7. The rotating arm 8 can be bent 90° toward the inner side of the swing arm 4 by the cylinder drive.

[0024] Furthermore, the swing arm 4 is provided with third positioning threaded holes 42 , and the sliding rod 7 is provided with a plurality of third adjusting bolts 70 threadably matched with the third positioning threaded holes 42 .

[0025] Furthermore, a universal joint 60 is provided on the output shaft of the driving cylinder 6, and a connecting groove 41 is provided on the swing arm 4 for hinged cooperation with the universal joint 60. The end of the driving cylinder 6 away from the output shaft is hingedly connected to a U-shaped base 21, and the bottom of the U-shaped base 21 is fixedly connected to the fixed plate 2.

[0026] Furthermore, a sliding motor fixing seat 9 is provided at the bottom of the driving arm 1, a driving motor 90 is provided in the motor fixing seat 9, a rack 10 is provided on the driving arm 1, and a gear 91 which is in transmission cooperation with the rack 10 is provided on the output shaft of the driving motor 90.

[0027] Working principle: When the practical unpacking robot is unpacking, the driving arm 1 is first driven by the driving motor 90 to move toward the silo. When the driving arm 1 moves to the silo, the first suction nozzle 33 and the second suction nozzle 40 will start to absorb the two sides of the folded carton respectively. When the carton is absorbed, the driving motor 90 drives the driving arm 1 to return to the original position to realize the removal of the carton. When the carton is taken out of the silo, the driving cylinder 6 is started, such as Figure 3 As shown, the driving cylinder 6 will drive the swing arm 4 to rotate 90° around the two rotating seats 5. During the rotation of the swing arm 4, the carton that is always in the adsorption state will be pressed by the rotation of the swing arm 4 and slowly open. When the swing arm 4 rotates to 90°, the carton will be completely opened and in an open state to achieve unpacking.

[0028] In addition, in order to facilitate the next packing step, the rotating arm 8 arranged at the bottom of the swing arm 4 can realize a 90° flip when the carton is fully opened, thereby driving one of the bottom covers of the carton to flip and fold, so that the bottom of the carton can be quickly folded when entering the next step.

[0029] It should be noted that the practical unpacking robot can adjust the positions of the first suction nozzle 33 and the second suction nozzle 40 according to the size of the carton, so that the first suction nozzle 33 and the second suction nozzle 40 are always in the center position of the carton to achieve stable material removal and unpacking.

[0030] When adjusting the first suction nozzle 33, loosen the second adjustment bolt 302 so that the adjustment rod 30 can slide left and right along the upper end of the fixing plate 2 to adjust the position. When the position adjustment is completed, tighten the second adjustment bolt 302 again. Then, loosen the first adjustment bolt 310 in the same way to adjust the distance between the two fixing rods 31 to achieve a better adsorption effect.

[0031] When the adjustment of the first suction nozzle 33 is completed, the third adjusting bolt 70 is loosened in the same manner to adjust the position of the sliding rod 7 to slide left and right along the swing arm 4 to adjust the second suction nozzle 40, which is very convenient and practical.

[0032] The practical box opening robot can realize adsorption and opening of the box through the cooperation of the swing arm 4 and the suction nozzle, thereby achieving the purpose of improving production efficiency and saving manufacturing costs.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
