The high efficiency of daily production work requires automatic identification of production machinery. On the one hand, it can automatically identify the thickness, hardness, rebound force, etc. of the packaging material, and use computer feedback to adjust the motion range of the manipulator to ensure that it does not rebound. On the other hand, a variety of different products, such as chocolates or snacks of different shapes, are packed in the same box, and their arrangement is regular. The products delivered by the production line are disordered, and the probes can be used to swipe to determine the different shapes. The position of the material is fed back to the different manipulators, and it will accurately place the items in the tray in the correct position and direction, quickly and accurately, eliminating the visual and finger fatigue of manual operation.
