[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 An inductive front positioning mechanism comprises: a bracket 1; a transition plate mounted on the bracket 1; a support 2 mounted on the transition plate; a cylinder 3 mounted on the first end of the support 2; a slide rod 4 mounted on the second end of the support 2, the piston rod of the cylinder 3 being connected to the first end of the slide rod 4; a positioning block 5 mounted on the second end of the slide rod 4, capable of blocking a blank; and a sensing mechanism mounted on the positioning block 5, capable of sensing the blank. When the blank is conveyed to the punching station, the positioning block 5 can position the blank, and the sensing mechanism can sense whether a blank is present, thereby preventing empty cutting.

[0027] The sensing mechanism includes an induction switch 7 and a rotating arm 6, which is hinged near the middle of the rotating arm 6 to the positioning stop 5. The first end of the rotating arm 6 can contact the blank. The induction switch 7 is mounted on the second end of the slide bar 4 and senses the second end of the rotating arm 6. Contact between the workpiece and the positioning stop 5 is only detected when the blank contacts the positioning stop 5, pushing the first end of the rotating arm 6 and causing the second end of the rotating arm 6 to approach the induction switch 7 and be sensed by the induction switch 7. When the blank is conveyed to the punching station, the positioning stop 5 can position the blank, and the sensing mechanism can detect the presence of the blank to prevent empty cutting.

[0028] The transition plate is adjustably mounted on the bracket 1; a waist-shaped hole is provided on the transition plate; the transition plate is adjustably mounted on the bracket 1 through the waist-shaped hole and bolts. By adjusting the installation position of the transition plate, it can adapt to different usage environments.

[0029] There is also an adjustment mechanism for adjusting the transition plate. The adjustment mechanism has a tensioning block 8, which is fixedly mounted on the bracket 1. The tensioning block 8 is provided with an adjustment rod 9, which is threadedly connected to the tensioning block 8. The first end of the adjustment rod 9 contacts the transition plate. By moving the adjustment rod 9 on the tensioning block 8, the transition plate is squeezed to achieve the adjustment function. At the same time, the adjustment rod 9 transition plate can also withstand the impact force brought by the sheet.

[0030] The L-shaped rotating arm 6 extends from the mounting slot of the positioning stop 5. Contact between the workpiece and the positioning stop 5 is only detected when the workpiece contacts the positioning stop 5, pushing the first end of the rotating arm 6 and the second end of the rotating arm 6 approaches the sensor switch 7, where it is sensed. When the workpiece is conveyed to the punching station, the positioning stop 5 positions the workpiece, and the sensing mechanism detects the presence of the workpiece, preventing empty cutting.

[0031] Two adjusting rods 9 are provided on the tensioning block 8, making the adjustment more stable and reliable.

[0032] After adopting the above structure, when the sheet is conveyed to the punching station, the sheet can be positioned and whether there is a sheet can be sensed to prevent empty cutting.
