The drive motor drives the transmission belt to rotate.

[0026] like Figure 3 As shown, the servo positioning mechanism includes a servo module 2.1, a limit switch 2.2, a first positioning plate 2.3, a first positioning roller 2.4, a support base 2.5, a first servo cylinder 2.6, and a second positioning roller 2.7. The servo module is fixed to one side of the worktable. The first positioning plate is connected to the movable end of the servo module. The first positioning roller is mounted on the top of the first positioning plate. The support base is fixed to the other side of the worktable. The first servo cylinder is fixed to the support base. The second positioning roller is connected to the piston rod of the first servo cylinder. The second positioning roller is connected to a sliding sleeve fixed to the top of the first cylinder via a guide rod 2.8. The servo module drives the first positioning plate and the first positioning roller to move. This device has four sets of this mechanism, with the specific positions set according to the workpiece position. The first servo cylinder drives the second positioning roller to move up and down, positioning the workpiece from the height direction. This device has two sets of this structure.

[0027] like Figure 4As shown, the lifting mechanism includes a second servo cylinder 3.1, a lifting support 3.2, a connecting seat 3.3, a linear guide connecting piece 3.4, a linear guide assembly 3.5, a first adjusting block 3.6, a second adjusting block 3.7, and an adjusting bolt 3.8.

The second servo cylinder drives the lifting support to move up and down. Since the two ends of the lifting support are in sliding fit with the linear guide assembly through the linear guide connecting piece, the adjusting bolt is rotated to adjust the angle of the second adjusting block.

[0028] As shown in Figure 5 and Figure 6 As shown, the angle adjusting mechanism includes a cylinder 4.1, a cylinder support 4.2, a first limiting bolt 4.3, a cylinder head limiting block assembly 4.4, a first connecting piece 4.5, a second connecting piece 4.6, a second limiting bolt 4.7, and a transmission connecting shaft 4.8.
