[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 5The utility model provides a suction structure for metal thin plates, which includes a base 1, and sliders 2 are symmetrically arranged on the front and rear sides of the lower end of the base 1. The sliders are slidably matched on the gantry slide rails, and the lateral movement of the structure is controlled by a stepping motor. A lifting block 3 is slidably matched in the middle of the base 1 for moving up and down. A cylinder 4 for driving the lifting block 3 to move up and down is downwardly arranged on the upper end of the base 1. A crossbeam 5 is horizontally arranged at the end of the lifting block 3. The lifting block 3 and the crossbeam 5 are connected by an L-shaped connecting block. Longitudinal beams 6 are adjustable on the left and right sides of the crossbeam 5. Adjustment holes are symmetrically opened on the front and rear sides of the upper end of the longitudinal beam 6. A mounting assembly 8 is adjustable front and back at the adjusting hole. A pneumatic suction cup 9 is arranged at the bottom of the mounting assembly 8. The position of the pneumatic suction cup can be adjusted front and back, left and right to adapt to thin plates of different sizes. By installing the structure on the gantry slide rail and controlling the lateral movement of the structure through a stepper motor, the sucked thin plate can be automatically transported to the shearing machine. The cylinder drives the lifting block and the components on it to descend, and the pneumatic suction cup contacts and sucks the top thin plate. Then, the pneumatic suction cup rises with the thin plate while the cylinder rises and resets. The structure is laterally moved to the shearing machine with the thin plate. The cylinder drives the lifting block and the components on it to descend, and the pneumatic suction cup releases the thin plate that falls on the shearing machine. After the cylinder rises and resets, the device is laterally moved and reset.

[0018] The cross beam 5 is provided with an adjustment frame 7, which is locked to the cross beam 5 by a first locking bolt, and the longitudinal beam 6 is connected to the bottom of the adjustment frame 7. The position of the longitudinal beam is adjusted left and right by the adjustment frame, thereby adjusting the left and right position of the pneumatic suction cup to meet the requirements of thin plates of different widths.

[0019] The erection assembly 8 includes a first T-block 8.1 and a second T-block 8.2 arranged at the upper and lower sides of the adjustment hole. A connecting rod 8.3 connected to the bottom of the pneumatic suction cup 9 is vertically arranged on the first T-block 8.1 and the second T-block 8.2. The first T-block 8.1 and the second T-block 8.2 are locked to the longitudinal beam 6 by the second locking bolt 8.4. The pneumatic suction cup and the connecting rod are placed in the middle of the longitudinal beam to avoid lateral force on the longitudinal beam. The second locking bolt passes through the first T-block and the second T-block and is tightened so that the first T-block and the second T-block are clamped to the longitudinal beam. The position of the pneumatic suction cup is adjusted forward and backward to meet the requirements of thin plates of different lengths.

[0020] See also Figure 3 , Figure 4 , and also includes an L-shaped frame plate 10 connected to the upper end of the crossbeam 5, a vertical rod 12 is passed through the frame plate 10, a disc 13 is arranged at the upper end of the vertical rod 12, and a sensor 11 for sensing the disc 13 is longitudinally arranged at the upper end of the frame plate 10. The cylinder drives the lifting block to descend, the pneumatic suction cup contacts the thin plate, the vertical rod brings the disc up, and after the sensor senses the disc, it transmits a signal to the industrial computer, the industrial computer controls the cylinder to stop descending, and the pneumatic suction cup sucks the thin plate, so that the needle adapts to the continuously lowered thin plate, and the thin plates are stacked from top to bottom.

[0021] A stabilizing block is arranged on the right side of the middle end of the lifting block 3, and the piston rod of the cylinder 4 is connected to the stabilizing block.
