The robot drives the device to drive the cut strapping tape to the recycling position at the same time. In this process, the strapping tape is pulled out of the carton stack, and the strap positioning cylinder retracts to release the strapping tape. After all the strapping tapes of the carton stack are removed in this way, the suction cup telescopic cylinder extends to drive the six groups of buffer suction cups 220 at the bottom of the suction cup bracket 210 to descend, so that the grabbing plane of the buffer suction cups 220 is lower than the working bottom surface of the tape cutter 420 and the first strap shovel plate 450 and the second strap shovel plate 460. The buffer suction cups 220 vacuum absorb the carton, and then the robot drives the device to place the grabbed carton in the carton loading warehouse of the carton filling and sealing machine to complete the carton loading action.

The plurality of buffer suction cups 220 are arranged in an array. The buffer suction cups 220 in the array together constitute an adsorption surface, which jointly adsorbs and releases the carton, thereby further increasing the grasping stability of the carton.

[0053] The buffer suction cups 220 at the bottom of the first grabbing assembly 200 and the second grabbing assembly 300 are arranged in a 3×5 array, and a total of 30 groups of buffer suction cups 220 work together to adsorb and grab the carton. Those skilled in the art can also adaptively adjust the number of buffer suction cups 220 according to actual needs, which all falls within the protection scope of this embodiment.
