Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] like Figure 1-2 As shown, a steel plate suction and transfer machine includes a long, rectangular fixed frame 1 and two U-shaped supports 11 respectively located at both ends of the bottom of the fixed frame 1. The U-shaped supports 11 are respectively located at both ends of the fixed frame 1, providing suspended support for the fixed frame 1. A suction and transfer space for the steel plate is formed between the two U-shaped supports 11 below the fixed frame 1 for lateral transport of the steel plate. A cavity 12 is provided in the middle of the fixed frame 1, and a movable seat 2 that can move along the length of the fixed frame 1 is provided in the middle of the cavity 12. The movable seat 2 can move within the cavity 12 along the length of the cavity 12. A base frame 3 is provided below, which can move up and down relative to the movable seat 2. The base frame 3 is connected to the movable seat 2 by a transmission, so that the base frame 3 can drive the steel plate to move up and down relative to the movable seat 2 through the first suction nozzle 32 and the second suction nozzle 33 to adjust the height of the steel plate. The base frame 3 includes two connecting rods 31 arranged parallel to each other on both sides of the base frame 3. The bottom of one end of the connecting rod 31 is provided with a first suction nozzle 32 that can move automatically vertically, and the bottom of the other end of the connecting rod 31 is provided with a second suction nozzle 33. The first suction nozzle 32 and the second suction nozzle 33 are both existing technologies and can be used for transmission. Vacuum adsorption of the steel plate is achieved through external air pump suction, thus fixing the steel plate. A vertically positioned movable rod 34, which can elastically float up and down, is located at the end of the connecting rod 31 above the second suction nozzle 33. When the first suction nozzle 32 approaches the steel plate, it automatically moves down to adsorb and connect with the steel plate, subsequently lifting the steel plate for suction and transfer. The second suction nozzle 33 is connected to the bottom end of the movable rod 34, and the second suction nozzle 33 elastically floats up and down synchronously with the movable rod 34. When the first suction nozzle 32 moves down to adsorb the steel plate, the second suction nozzle 34... 3. Synchronous downward movement: When the first suction nozzle 32 is fully adsorbed with the steel plate, the second suction nozzle 33 moves downward synchronously to adsorb the steel plate. The second suction nozzle 33 adapts to the downward movement range of the second suction nozzle 33 through the elastic floating of the movable rod 34, and presses the second suction nozzle 33 into contact with the steel plate through elasticity, maintaining the adsorption connection with the steel plate and avoiding some suction nozzles failing to adsorb onto the steel plate. This effectively ensures the full adsorption and fixation of the steel plate, prevents the steel plate from falling during suction lifting and transfer, and avoids the need for additional drive components due to the up and down movement of each suction nozzle, thus increasing purchase and control costs.

[0018] like Figure 2-3As shown, the end of the connecting rod 31 is provided with a vertically positioned driving cylinder 35 above the first suction nozzle 32 for driving the first suction nozzle 32 to move vertically. The cylinder rod of the driving cylinder 35 is set downward and connected to the top of the first suction nozzle 32. The driving cylinder 35 can drive the first suction nozzle 32 to move up and down. When the first suction nozzle 32 moves above the steel plate, the first suction nozzle 32 driven by the driving cylinder 35 moves down to adsorb and fix the steel plate. Then, the base frame 3 drives the steel plate to move up through the first suction nozzle 32 and the second suction nozzle 33 to achieve the suction and transfer of the steel plate. The two first suction nozzles 32 are arranged diagonally opposite each other, and the two second suction nozzles 33 are arranged diagonally opposite each other, so that the adsorption of the first suction nozzles 32 and the second suction nozzles 33 on the steel plate is more reliable. The first suction nozzles 32 are evenly distributed, so that the adsorption of the first suction nozzles 32 on the steel plate is more reliable, ensuring that both diagonally opposite first suction nozzles 32 can fully adsorb and lift the steel plate, and enhancing the stability when lifting the steel plate.

[0019] like Figure 3-4 As shown, a connector 311 is provided on the side wall of the connecting rod 31. A guide cylinder 312 is vertically arranged and sleeved on the connecting rod 311. The guide cylinder 312 is fixed to the top of the connecting rod 311 and is vertically arranged. The movable rod 34 is inserted into the guide cylinder 312 and can slide axially relative to the guide cylinder 312. An annular limiting seat 341 is provided at the lower part of the movable rod 34 corresponding to the lower part of the guide cylinder 312. A telescopic spring 342 is provided between the annular limiting seat 341 and the guide cylinder 312. The two ends of the telescopic spring 342 are respectively connected to the annular limiting seat 341 and the guide cylinder 312. The two ends of the telescopic spring 342 act on the annular limiting seat 341 and the guide cylinder 312 respectively. When the second suction nozzle 33 contacts the steel plate, the movable rod 34 adaptively moves upward along the guide cylinder 312 to adapt to the displacement of the first suction nozzle 32. The telescopic spring 342 retracts. After the plate is lifted and moved to the designated position, the suction of the first suction nozzle 32 and the second suction nozzle 33 is released, and the steel plate is placed in the designated position. The movable rod 34 is driven by the telescopic spring 342, which drives the first suction nozzle 32 to automatically move back to its original position. The movable rod 34 has an axially arranged through hole 343 in the middle. The top of the second suction nozzle 33 has a connector 331 that is threaded to the lower end of the through hole 343. The second suction nozzle 33 is fixed by the threaded connection between the top connector 331 and the through hole 343. The top of the movable rod 34 has a limiting nut 344 that is threaded to the upper end of the through hole 343 and is located above the guide cylinder 312. The outer wall of the limiting nut 344 protrudes from the outer wall of the movable rod 34. The limiting nut 344 is threaded to the top of the movable rod 34 to limit the movement of the movable rod 34 and prevent the movable rod 34 from moving down too far and detaching from the guide cylinder 312, thus ensuring the stability and reliability of the structure.

[0020] like Figure 1-3As shown, the fixed frame 1 has linear guide rails 13 on both sides of the cavity 12, arranged along the moving direction of the movable seat 2. The bottom sides of the movable seat 2 are connected to the movable parts of the linear guide rails 13. The linear guide rails 13 are existing technology and will not be described in detail here. The two linear guide rails 13 are respectively arranged on both sides of the cavity 12 on the fixed frame 1, which can support and guide the movement of the movable seat 2. The movement of the movable seat 2 along the linear guide rails 13 can be driven by a motor with a lead screw structure, or by a rodless cylinder. The movable seat 2 is located above the base frame 3 and is movably connected to the middle of the base frame 3. A base plate 21 is provided below the movable seat 2. Multiple columns 211 connected to the movable seat 2 are provided along the edge of the base plate 21. The movable seat 2 is connected to the edge of the base plate 21 via these columns 211. The base plate 21 and the movable seat 2 form a single unit through these columns 211. The movable seat 2 and the base plate 21 can move along the linear guide rail 13. A vertically arranged lifting cylinder 22 is provided in the center of the top surface of the base plate 21. The bottom of the lifting cylinder 22 is equipped with... The base frame 3 includes a connecting plate 36 located below the base plate 21. The cylinder rod of the lifting cylinder 22 passes through the base plate 21 and connects to the connecting plate 36. The end of the cylinder rod of the lifting cylinder 22 is connected to the connecting plate 36 on the base frame 3. When the lifting cylinder 22 is activated, it can drive the base frame 3 through the connecting plate 36 to drive the first suction nozzle 32 and the second suction nozzle 33 to lift and lower synchronously, thereby achieving the suction, lifting and lowering of the steel plate. After the steel plate is lifted, the movable seat 2 can drive the base plate 21 and the base frame 3 to move synchronously along the linear guide rail 13. To achieve the transfer and transportation of steel plates, vertically arranged limiting cylinders 23 are provided on the top surface of the base plate 21 corresponding to both sides of the lifting cylinder 22. A guide rod 24 that can slide up and down is passed through the limiting cylinder 23. The bottom end of the guide rod 24 is connected to the connecting plate 36. The connection between the guide rod 24 and the connecting plate 36 and the cooperation with the limiting cylinder 23 play a limiting and guiding role when the base frame 3 is lifted and moved, which enhances the structural stability and structural strength when the lifting cylinder 22 drives the base frame 3, and improves the smoothness during lifting.
