Method for opening box by cutting packing tape with laser

Abstract

The invention relates to a method for opening a box by cutting a packing tape with laser, and the method comprises the following steps: (1) placing a box, which is sealed by using a tape, on a running production line; (2) utilizing a photoelectric sensor to judge whether the box is in an operation scope of a laser device, and utilizing the laser device to cut the tape at one vertical side of the sealed box according to a judgment result of the photoelectric sensor; (3) utilizing a distance sensor to detect the joint position between the tape and the box cover, judging an accurate position of the joint between the tape and the box cover according to a loss signal of the distance sensor, and cutting the joint between the tape and the box cover through the laser device according to the judgment of the distance sensor; and (4) performing distance conversion by utilizing a central control unit to instruct the laser device to cut the tape at the other vertical side of the box. By adopting the technical scheme, the laser device can automatically cut the tape on the box according to the instruction of the central control unit, and the manual direct operation is unnecessary, so the operation efficiency is high, and the working intensity is low.

Description

technical field [0001] The invention belongs to the field of unpacking methods, in particular to an unpacking method utilizing laser cutting sealing tape. Background technique [0002] Packaging boxes are generally sealed with sealing tape. In practice, the packaging box is generally opened manually. Specifically, the worker uses a blade to cut the sealing tape at the joint of the box cover to achieve the goal of opening the box. Although this approach is relatively simple and feasible, it also has the following disadvantages: [0003] 1. The sharp blade is easy to scratch the worker's fingers, especially in the case of assembly line operation, if the blade is not well moved along the middle seam of the box cover, the blade will rebound when encountering resistance, which is likely to cause industrial accidents; [0004] 2. Manual operation of the blade is not easy to control the depth of the blade into the box, which may scratch the objects in the box, resulting in defecti...
