The linear module 11 is started to drive a plurality of sliders 1101 to move. The movement of the plurality of sliders 1101 drives the support plate 12 to move, so that the steel sheet 5 can be driven for conveying.

[0042] The lifting component includes a motor 14 fixed inside the machine body 1. A connecting shaft 15 is rotatably connected inside the machine body 1.

When the two first bevel gears 16 rotate, they drive the two second bevel gears 21 to rotate, thereby driving the two screw rods 20 to rotate simultaneously. When the two screw rods 20 rotate, they drive the two lifting rods 19 to move downward, thereby driving the mounting plate 10 to move downward, so that the vacuum suction cup 13 abuts against the upper end of the steel sheet 5. Start the vacuum suction cup 13 to suck the steel sheet 5, and drive the mounting plate 10 to reset through the lifting assembly, so that the steel sheet 5 can be lifted. Start the linear module 11 to drive the plurality of sliders 1101 to move. The movement of the plurality of sliders 1101 drives the support plate 12 to move, thereby driving the steel sheet 5 to be conveyed to the required position. Then place the steel sheet 5 on the upper end of the second placing plate 6, so that the steel sheet 5 is inserted into the positioning block 22, thereby positioning the steel sheet 5. Control the steel sheet conveying mechanism to reset, and then suck up a steel sheet 5 on the upper end of the first placing plate 3 through the steel sheet conveying mechanism, and simultaneously suck up a steel sheet 5 on the upper end of the second placing plate 6, and drive the two steel sheets 5 to move to the required position. Then place the two steel sheets 5 on the upper end of the second placing plate 6, and position the two steel sheets 5 through the positioning assembly. Control the steel sheet conveying mechanism to reset, and then suck up a steel sheet 5 on the upper end of the first placing plate 3 through the steel sheet conveying mechanism, and simultaneously suck up two steel sheets 5 on the upper end of the second placing plate 6, and drive the three steel sheets 5 to move to the required position. Then put down the three steel sheets 5 through the steel sheet conveying mechanism, so that one of the steel sheets 5 is placed at the stamping part of the stamping device 2, and the other two steel sheets 5 are placed on the upper end of the second placing plate 6, and position the two steel sheets 5 through the positioning assembly. Control the steel sheet conveying mechanism to reset, start the stamping device 2 to stamp the steel sheet 5, so that the steel sheet 5 can be stamped into a motor punching sheet. At the same time, by providing a lifting assembly, when the steel sheet conveying mechanism sucks up a steel sheet 5 on the upper end of the first placing plate 3, start the servo electric cylinder 9 to drive the connecting plate 8 to move upward. The upward movement of the connecting plate 8 drives the first placing plate 3 to move upward through the plurality of guide rods 7, so as to drive a plurality of steel sheets 5 placed on the upper end of the first placing plate 3 to move upward to the required position, so that the steel sheet conveying mechanism can effectively suck up the steel sheet 5.
