[0045] Furthermore, such as Figures 13 to 16As shown, in order to adsorb workpieces of different sizes, the adsorption workpiece stage includes a connecting block 203. A connecting chamber is provided on one side of the connecting block 203. A vacuum pump 202 is fixedly connected to one side of the connecting chamber. A plurality of first connecting holes are provided on one side of the connecting chamber. A first suction cup 204 is slidably connected inside the first connecting holes. A connecting hole is provided on one side of the first suction cup 204. A locking block 205 is fixedly connected to one side of the first suction cup 204. A side plate 206 is fixedly connected to one side of the first suction cup 204. A slide rod 207 is slidably connected to one side of the side plate 206. One side of the slide rod 207 is fixedly connected to the inside of the connecting chamber. A first spring 208 is fixedly connected to one side of the side plate 206. One side of the first spring 208 is fixedly connected to one side of the connecting chamber.

[0046] Sliding parts 209 are provided on both sides of the connecting compartment. Several locking grooves 210 are provided on one side of the sliding part 209. A second spring 211 is fixedly connected to one side of the sliding part 209. One side of the second spring 211 is fixedly connected to one side of the slide plate 406. A positioning rod 212 is slidably connected to one side of the sliding part 209. One side of the positioning rod 212 is fixedly connected to one side of the slide plate 406. A disassembly groove is provided on one side of the sliding part 209.

[0047] A guide block 213 is fixedly connected to one side of the connecting block 203. Both sides of the guide block 213 are inclined surfaces. A disassembly block 214 is provided on one side of the guide block 213. A vertical rod 215 is fixedly connected to one side of the disassembly block 214.

[0048] A connecting hole is provided on the first suction cup 204. When the first suction cup 204 is not under force, the connecting hole is located in the middle of the first connecting hole and is blocked by the side wall of the first connecting hole. At this time, the first suction cup 204 does not work.

[0049] Depending on the workpiece size, the number of contacts between the first suction cup 204 and the workpiece varies as the first suction cup 204 moves downward. The first suction cup 204 in contact with the workpiece moves upward under force, causing the connecting hole to move into the interior of the connecting chamber, where it connects. At this time, the first suction cup 204 not in contact with the workpiece remains stationary. As the first suction cup 204 moves, it drives the side plate 206 to move under the limit of the slide rod 207, simultaneously compressing the first spring 208. The locking block 205 moves synchronously with the first suction cup 204. The locking block 205 moves into the locking groove 210. As the locking block 205 moves into the locking groove 210, the sliding member 209 is subjected to force and moves, and simultaneously squeezes the second spring 211. When the locking block 205 is completely placed inside the locking groove 210, the second spring 211 is no longer subjected to force, pushes the sliding member 209 back, and locks the locking block 205, locking the first suction cup 204. At this time, with the cooperation of the vacuum pump 202, the connecting chamber and the connecting hole, the locked first suction cup 204 forms a vacuum to adsorb the workpiece.

[0050] When the workpiece moves toward the punch press, that is, when the connecting block 203 moves toward the punch press, the movement of the connecting block 203 drives the guide block 213 to move. When one side of the guide block 213 contacts the disassembly block 214, the disassembly block 214 is forced to move upward, causing the upright 215 to move under the limit of the mounting plate 216, and simultaneously squeezing the third spring 217. After the position of the connecting block 203 moves to the set position, the guide block 213 no longer contacts the disassembly block 214. At this time, the third spring 217 is no longer under force and pushes the disassembly block 214 back. The disassembly block 214 moves into the disassembly groove, causing the sliding member 209 to be forced to move, causing the locking block 205 to disengage from the locking groove 210, releasing the locking of the first suction cup 204. Under the push of the first spring 208, the first suction cup 204 is reset.

[0051] Unlike the first embodiment, this improved embodiment can perform loading operations on workpieces of different sizes and shapes.

[0052] The working principle of the feeding mechanism of a sheet metal stamping device is as follows:

[0053] The electric push rod 6 drives the first drive mechanism 3, the second drive mechanism 4, and the adsorption workpiece stage 2 to move downwards, so that the suction cup 201 contacts the sheet metal workpiece. With the cooperation of the vacuum pump 202, the suction cup 201 generates an adsorption force to adsorb the workpiece. Then the electric push rod 6 resets and drives the workpiece to move upwards, so that the height of the workpiece is flush with the height of the workpiece placement area of ​​the punch press. When the electric push rod 6 moves upwards, the first connecting frame 315 moves upwards synchronously. The movement of the first connecting frame 315 drives the first gear 302 to move on the first rack 301. The first gear 302 rotates while moving upwards. When the first connecting frame 315 moves upwards under the installation direction of the first inner ratchet 308 and the first pawl 309, the first inner ratchet 308 rotates with the rotation of the first gear 302.

[0054] The rotation of the first inner ratchet 308 drives the first connecting plate 307 to rotate, the first connecting plate 307 drives the first intermediate rod 306 to rotate, and the rotation of the first intermediate rod 306 drives the first coil spring 303 to coil up. At this time, under the installation direction of the second inner ratchet 310 and the second pawl 312, the first inner ratchet 308 drives the first intermediate rod 306 to rotate, which in turn drives the second inner ratchet 310 to rotate, but the fixing block 311 does not rotate accordingly.

[0055] When the first connecting frame 315 is raised to the designated position, the first gear 302 stops moving. At this time, the first coil spring 303 stops winding and changes from a wound state to a released state, causing the first intermediate rod 306 to reverse. At this time, the first intermediate rod 306 drives the first connecting plate 307 to rotate, which in turn drives the first inner ratchet 308 and the second inner ratchet 310 to rotate. Under the installation directions of the first pawl 309 and the first inner ratchet 308, and the second pawl 312 and the second inner ratchet 310, the first gear 302 rotates and the fixing block 311 rotates. The rotation of the fixed block 311 drives the lead screw 304 to rotate, the rotation of the lead screw 304 drives the slider 313 to move, the movement of the slider 313 drives the second connecting frame 404 to move, the second connecting frame 404 drives the second gear 402 to move synchronously, the second gear 402 moves on the second rack 401, so that the second gear 402 rotates synchronously, which in turn causes the third rack 403 to move, the movement of the third rack 403 drives the slide plate 406 to move, the movement of the slide plate 406 drives the connecting block 203 to move, which in turn drives the workpiece to move towards the position of the punch press;

[0056] When the connecting block 203 moves to the designated position, one side of the slide plate 406 contacts one side of the second connecting frame 404, causing the press switch 407 to contact the press block 408, turning off the vacuum pump 202, so that the workpiece is placed in the placement area of ​​the punch press.

[0057] The lead screw 304 rotates synchronously with the second connecting plate 505, which in turn rotates the second intermediate rod 504. The second intermediate rod 504 then rotates the second coil spring 501. When the first coil spring 303 is fully released, the second coil spring 501 finishes coiling and changes from coiled to released, causing the second intermediate rod 504 to reverse, which in turn causes the lead screw 304 to reverse, resetting the first drive mechanism 3 and the second drive mechanism 4. This moves the adsorption workpiece table 2 from the position of the punch press to above the conveyor belt. When the slide plate 406 moves to the other side, the pressing block 408 on the other side cooperates with the pressing switch 407 to turn on the vacuum pump 202.
