[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: Please refer to Figures 1 to 6 The present invention provides a technical solution: an automatic pick-and-place device for sheet metal processing, including a processing table 1, a movable base 11 and a three-axis slide 12. The movable base 11 is disposed on the side of the processing table 1, and the three-axis slide 12 is fixedly installed on the processing table 1. The three-axis slide 12 is provided with a pick-and-place component, which includes a suction module and a clamping module. The suction module and the clamping module cooperate with each other to pick up and place the sheet metal. The suction module includes a fixed plate 2 fixedly installed on a three-axis slide table 12. A support frame 21 is fixedly installed at the bottom of the fixed plate 2, and a cylinder suction cup 22 is fixedly installed at each of the four corners of the support frame 21. The clamping module includes a bidirectional hydraulic cylinder 23, which is fixedly installed in the middle of the fixed plate 2. A power block 24 is fixedly installed on the output shaft of the bidirectional hydraulic cylinder 23. A guide post 25 is fixedly installed on the fixed plate 2, and the guide post 25 is located below the bidirectional hydraulic cylinder 23. The power block 24 is movably installed on the outer surface of the guide post 25. A fixed frame 26 is fixedly installed at the bottom of the power block 24. Support columns 27 are fixedly installed on both sides of the inner surface of the fixed frame 26. A first limit block 28 is fixedly installed at the end of the support column 27 away from the fixed frame 26. A reset spring 29 is sleeved on the outer surface of the support column 27. A clamping member 210 is movably installed on the outer surface of the support column 27. A positioning component 211 is fixedly installed on the inner surface of the fixed frame 26, and a separating component 212 is fixedly installed on the side of the positioning component 211 away from the fixed frame 26. The separating member 212 is located below the clamping member 210, and the separating member 212 is made of a metal spring sheet. The positioning member 211 is located between the fixing frame 26 and the clamping member 210. The support frame 21 is in the shape of an "I" and the two eccentric parts 35 are located on both sides of the support frame 21; The diameter of the first limiting block 28 is larger than the diameter of the support column 27. One end of the reset spring 29 is fixedly connected to the inner surface of the fixed frame 26, and the other end is fixedly connected to the clamping member 210.

[0019] Specifically, when using the equipment, first move it to the stacking area of ​​the boards, then start the three-axis slide 12 to drive the support frame 21 to descend, so that the cylinder suction cup 22 contacts the boards and starts the cylinder suction cup 22 to adsorb the boards. Then start the three-axis slide 12 to rise fifty to eighty centimeters and then hover. If there is no excessive suction of the sheet material, the material can be loaded directly by moving the mobile equipment. If there is excessive suction of the sheet material, the bidirectional hydraulic cylinder 23 needs to be activated to drive the power block 24 to move, so that the power block 24 drives the fixed frame 26 to move, and the fixed frame 26 drives the clamping part 210 to move, so that the clamping part 210 contacts the sheet material. When the clamping member 210 contacts the plate, as the fixing frame 26 continues to move, the clamping member 210 will squeeze the return spring 29, causing the return spring 29 to undergo compression deformation. At this time, the clamping member 210 clamps the plate to be taken, while the separating member 212 will continue to move closer to the plate to be taken and insert into the gap between the plate to be taken and the plate to be taken, thereby separating the plate to be taken and the plate to be taken. Since the separating member 212 is made of metal spring sheet, during the separation process of the separating member 212, due to the interference of the plate to be taken, the angle between the end of the separating member 212 away from the positioning member 211 and the plate to be taken will be larger, making it easier to separate the plate to be taken from the plate to be taken, thus making it easier to take the plate. As separation proceeds, the clamping member 210 will eventually come into contact with the positioning member 211. At this point, the clamping member 210 will clamp the removed material, thus successfully clamping the removed material and removing any excess material.

[0020] Example 2: Please refer to Figures 1 to 5 A vibration assembly is provided on the bidirectional hydraulic cylinder 23. The vibration assembly includes a connector 3, which is fixedly installed on the outer surface of the output shaft of the bidirectional hydraulic cylinder 23. A rack 31 is fixedly installed at one end of the connector 3 away from the output shaft of the bidirectional hydraulic cylinder 23. A first slider 32 is fixedly installed at the bottom of the rack 31. The first slider 32 is movably installed inside the support frame 21. A groove adapted to the first slider 32 is opened inside the support frame 21. The rack 31 is meshed with a first gear 33 on its upper side. A rotating shaft 34 is fixedly installed in the middle of the first gear 33. Eccentric parts 35 are fixedly installed on both sides of the outer surface of the rotating shaft 34. The fixed plate 2 is in contact with the rotating shaft 34.

[0021] Based on Example 1, when the bidirectional hydraulic cylinder 23 is started, it will also drive the connecting member 3 to move, so that the connecting member 3 drives the rack 31 to move. The rack 31 can drive the first gear 33 to rotate, so that the first gear 33 drives the rotating shaft 34 to rotate. The rotating shaft 34 can drive the eccentric member 35 to rotate, so that the eccentric member 35 vibrates the plate. The vibration assists in the separation of the multi-absorbent plate, which can further remove the multi-absorbent plate. It is important to note that the vibration frequency and amplitude need to be controlled to avoid the vibration causing the return spring 29 to provide elastic force, which could cause the clamping part 210 to drop the plate during the clamping process. The separation component 212, in conjunction with the separation of the multi-absorption plate, can promote the separation of the multi-absorption plate. On the other hand, the separation component 212 is located below the plate being removed, which can support the plate being removed and further prevent the plate being removed from falling.

[0022] Example 3: Please refer to Figure 2 , Figure 7 and Figure 8 The support frame 21 is provided with a bottom support assembly, which includes a first mounting part 4. There are two first mounting parts 4, which are respectively located on both sides of the support frame 21. A double-shaft helical gear box 41 is fixedly mounted on the surface of the first mounting part 4. The end of the rotating shaft 34 is fixedly connected to the input shaft of the double-shaft helical gear box 41. A second gear 42 is fixedly mounted on the output shaft of the double-shaft helical gear box 41. An arc-shaped rack 43 is fixedly installed on one side of the second gear 42, and a second slider 44 is fixedly installed on one side of the arc-shaped rack 43. A second limiting block 45 is fixedly installed at the end of the second slider 44 away from the arc-shaped rack 43. A second mounting member 48 is fixedly installed on the upper surface of the first mounting member 4. A slide rail 46 is fixedly installed at the end of the second mounting member 48 away from the first mounting member 4. A drive groove 47 adapted to the second slider 44 is opened inside the slide rail 46, and the second slider 44 is movably installed in the drive groove 47. A mounting plate 49 is fixedly installed between the bottoms of the two arc-shaped racks 43, and a support member 410 is fixedly installed on one side of the mounting plate 49. The support member 410 is bent in shape. A spring column 5 is detachably connected to one side of the support member 410, and a spring ball 51 is fixedly installed at the end of the spring column 5 away from the support member 410.

[0023] Based on embodiment 2, when the rotating shaft 34 rotates, it can drive the second gear 42 to rotate through the double-shaft helical gear box 41, so that the second gear 42 drives the arc rack 43, thereby driving the mounting plate 49 and the support member 410. The cooperation between the second slider 44, the second limit block 45 and the slide rail 46 can make the support member 410 more stable when driven. During the movement of the support member 410, it will gradually approach the bottom of the plate being taken. If the multi-absorbent plate still does not fall in the above embodiment, the support member 410 will contact the multi-absorbent plate and squeeze the multi-absorbent plate, widening the gap between the plate being taken and the multi-absorbent plate, thereby accelerating the fall of the multi-absorbent plate and further promoting the separation of the plate being taken and the multi-absorbent plate. Under the continuous drive of the bottom support component 410, the bottom support component 410 supports the bottom of the plate being picked up when the clamping component 210 contacts the positioning component 211, further preventing the plate being picked up from falling off under the vibration of the eccentric component 35, making the loading process smoother. Furthermore, when the bottom support 410 contacts the bottom of the plate being taken, the elastic column 5 and the elastic ball 51 will shake under the action of inertia, thereby touching the bottom support 410 and causing the bottom support 410 to vibrate. When the bottom support 410 contacts the plate being taken, the vibration frequency of the plate being taken will be further increased after being supported by the bottom support 410, which will further promote the separation of the multi-absorbed plate and the plate being taken. During unloading, simply start the three-axis slide 12 to drive the support frame 21 down, so that the cylinder suction cup 22 contacts the board and starts the cylinder suction cup 22 to adsorb the board. Then move the equipment to complete the unloading.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
