[0022] The movably arranged grabbing assembly includes a moving seat 4, a guide rod 5 symmetrically arranged at the bottom of the moving seat 4, a lifting seat 6 sleeved on the outside of the guide rod 5, a vacuum cover 7 arranged at the bottom of the lifting seat 6, and the vacuum cover 7 is located on the inner side of the guide rod 5, a plurality of groups of spaced negative pressure shafts 8 slidably arranged on the inner side of the bottom of the vacuum cover 7, and a ring-shaped baffle is arranged on the top of the negative pressure shaft 8, a suction cup 9 arranged at the bottom end of the negative pressure shaft 8, a flow channel 10 opened inside the negative pressure shaft 8 and connected to the suction cup 9, a dust filter 11 arranged inside the flow channel 10 near the suction cup 9, a plurality of groups of self-adaptive springs 12 connected to the negative pressure shaft 8 arranged inside the vacuum cover 7, and a vacuum machine 13 arranged on one side of the vacuum cover 7, the self-adaptive spring 12 forms an elastic support for the negative pressure shaft 8, and the device is used to grab the plastic foam board. When the suction cup 9 is in contact with the surface of the plastic foam board, the suction cup 9 is squeezed upward by the plastic foam board, so that the negative pressure shaft 8 moves upward together with the suction cup 9. Therefore, when there is a protrusion on the surface of the plastic foam board, the negative pressure shaft 8 and the suction cup 9 at the protrusion can move upward, so that other groups of suction cups 9 can be smoothly attached to the plastic foam board to complete the preliminary fixation. When there is a depression on the surface of the plastic foam board, other groups of suction cups 9 can form negative pressure fixation for other areas. The inside of the vacuum cover 7 is evacuated by the vacuum machine 13, so that the suction cup 9 generates negative pressure, forming a stable grasping and fixing of the plastic foam board. The dust filter 11 arranged inside the flow channel 10 opened in the negative pressure shaft 8 can effectively prevent external dust from entering the flow channel 10 and affecting the circulation of gas when negative pressure is formed.
