[0002] At present, with the continuous advancement of science and technology and the rapid development of intelligent production, the production methods in the industrial field are undergoing profound changes. Among them, the widespread application of industrial robots has become a beautiful landscape in modern industrial production lines. These robots are gradually replacing traditional manual operations with their precise operation, efficient working ability and excellent stability, greatly improving the efficiency of the entire industrial production.

[0003] However, although the application of industrial robots has achieved remarkable results, there are still certain limitations in some aspects. When grasping and moving workpieces, the traditional industrial robot suction cups can usually only adsorb one plane of the workpiece at the same time. This means that when facing workpieces with different planes, these suction cups can often only adsorb one plane of the workpiece, and cannot achieve adsorption and fixation of different planes of the workpiece.

[0004] This limitation brings a series of problems. First, since it can only adsorb on one plane, the suction cup is often not strong enough for workpieces with complex shapes or irregular surfaces, which can easily cause the workpiece to fall off during transportation, causing unnecessary losses and risks to production. Secondly, this single adsorption method also limits the application scope of industrial robots, making them unable to cope with a variety of workpieces. Summary of the invention
