When the processed part is conveyed to the lifting box by the conveyor belt, under the action of the rollers, the processed part is slightly lifted on the rollers, making the edge of the processed part suspended. When grabbing, it can easily contact the lower edge of the processed part, effectively reducing the difficulty of grabbing and improving the grabbing efficiency. Description of the Drawings

Specific embodiments

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment 1:

[0038] Refer to Figure 1 、 Figures 3 - 6 , an automated grasping device for machining manufacturing, including a base 1, a grasping component, an anti-falling component, a cleaning component, a lifting component, and two storage components;

[0039] A conveyor 2 is fixedly installed on the base 1 for transporting workpieces. A first motor 5 is fixedly installed on the conveyor 2. The transmission shaft of the conveyor 2 is driven by the first motor 5, so that the belt on the conveyor 2 can work. A frame plate 16 is fixedly connected to the base 1. A cylinder 7 is provided on the frame plate 16 for lifting and lowering the grabbing assembly. A mounting plate 8 is fixedly connected to the output end of the cylinder 7. Three groups of brackets 21 are fixedly connected below the mounting plate 8 for installing the grabbing assembly. A support plate 18 is fixedly connected to the mounting plate 8. An electric telescopic rod 17 is fixedly installed on the support plate 18. The electric telescopic rod 17 is fixedly connected to one end of the first piston rod 29. The first piston rod 29 can be driven to move up and down by the electric telescopic rod 17. Three support tubes 23 are fixedly connected below the mounting plate 8 for fixedly supporting the second piston cylinder 25.

[0040] The grabbing assembly is used to grab the processed parts. The grabbing assembly consists of a pulling block 27, three grabbing arms 30 and three grabbing clamps 22. The three grabbing clamps 22 are rotatably connected to three groups of brackets 21 respectively. The three grabbing arms 30 are fixedly connected to the three grabbing clamps 22 respectively. The pulling block 27 is rotatably connected to the three grabbing arms 30. When the pulling block 27 is upward, it can drive the grabbing arms 30 upward to retract the three grabbing clamps 22 so that they can grab the processed parts.

[0041] The anti-fall component is used to prevent the processed parts from falling during the grasping process. The anti-fall component consists of a second piston cylinder 25, a suction cup 24, a second piston 32 and a second piston rod 33. The second piston cylinder 25 is fixedly connected to the three support tubes 23, the suction cup 24 is connected to the second piston cylinder 25, the second piston 32 is slidably connected in the second piston cylinder 25, the second piston rod 33 is slidably connected to the second piston cylinder 25, and the second piston rod 33 is fixedly connected to the second piston 32. When the second piston rod 33 drives the second piston 32 to move upward, negative pressure can be generated in the second piston cylinder 25, so that the suction cup 24 can tightly adsorb the grasped parts.

[0042] In this embodiment, the cylinder 7 drives the grasping assembly downward, so that the suction cup 24 moves downward. When the suction cup 24 is attached to the workpiece, the electric telescopic rod 17 drives the pulling block 27 through the first piston rod 29 to move the grasping arm 30 upward. While the three grasping clamps 22 are closed to grab the processed parts, the second piston 32, driven by the pulling block 27 and the second piston rod 33, generates negative pressure in the second piston cylinder 25, so that the suction cup 24 tightly adsorbs the workpiece, allowing the grasping assembly to grasp the workpiece more firmly, avoiding the workpiece from falling off due to shaking during transportation.

[0043] Embodiment 2:

[0044] Different from the first embodiment, Figure 1 - Figure 2 , Figure 8, this embodiment also has the following further content:

[0045] A lead screw 11 is provided on the shelf plate 16, a slide bar 10 is fixedly connected to the base 1, a first transmission wheel 35 is rotatably connected to the shelf plate 16, a second transmission wheel 36 is rotatably connected to the shelf plate 16, a belt 34 is wound around the outer sides of the first transmission wheel 35 and the second transmission wheel 36. When the first transmission wheel 35 rotates, it can drive the second transmission wheel 36 to rotate through the belt 34. A second motor 15 is fixedly installed below the shelf plate 16, and the transmission shaft of the second motor 15 is fixedly connected to the first transmission wheel 35. The first transmission wheel 35 can be driven to rotate through the second motor 15. A cylinder 7 is fixedly installed on the first transmission wheel 35, and the cylinder 7 can be driven to rotate through the first transmission wheel 35, so as to align the corresponding storage box 3 below the grasping assembly, facilitating the grasping assembly to put the grasped workpieces into the storage box 3. The lead screw 11 is fixedly connected to the second transmission wheel 36. When the second transmission wheel 36 rotates, the lead screw 11 can be rotated, so that the slider 12 rises or falls. One end of the lead screw 11 and the slide bar 10 are fixedly connected to the limiting plate 13 for limiting the slider 12.

[0046] The lifting assembly is used to lift the processing parts to facilitate grasping. The lifting assembly consists of a slider 12, a lifting box 14 and four rollers 37. The slider 12 is slidably connected to the lead screw 11 and the slide bar 10. The lifting box 14 is fixedly connected to the slider 12. The four rollers 37 are rotatably connected to the inner wall of the lifting box 14. When the workpiece is conveyed to the inside of the lifting box 14 by the conveyor belt, under the action of the rollers 37, the workpiece is slightly lifted on the rollers 37, making the edge of the workpiece suspended. When grasping, it can easily contact the lower edge of the workpiece, thus effectively reducing the difficulty of grasping and improving the grasping efficiency. The four rollers 37 do not fit with the belt on the conveyor 2 to prevent the rollers 37 from rotating along with the operation of the belt.

[0047] In this embodiment, when the second motor 15 drives the cylinder 7 to rotate through the first transmission wheel 35, the workpiece on the conveyor 2 is correspondingly positioned below the grasping assembly. At this time, the second transmission wheel 36 drives the lead screw 11 to rotate, causing the slider 12 to drive the lifting box 14 to descend and adhere to the conveyor belt on the conveyor 2. When the workpiece is conveyed by the conveyor belt into the lifting box 14, under the action of the rotating roller 37, the workpiece is slightly lifted on the rotating roller 37, making the edge of the workpiece suspended. When grasping, it can easily contact the lower edge of the workpiece, thereby effectively reducing the difficulty of grasping and improving the grasping efficiency. Subsequently, the first motor 5 is stopped to make the conveyor 2 stop working. The cylinder 7 is controlled to drive the grasping assembly to descend. After the workpiece is grasped by the grasping assembly, the cylinder 7 rises. Then, the cylinder 7 is driven by the second motor 15 to rotate, making the grasping assembly correspondingly positioned above the storage box 3. The cylinder 7 is controlled again to make the grasping assembly descend, and the workpiece is placed into the storage box 3. At the same time, under the action of the belt 34, the second transmission wheel 36 drives the lead screw 11 to rotate, causing the lifting assembly to rise to avoid affecting the normal operation of the conveyor 2. Finally, the first motor 5 is started to make the conveyor 2 continue to work.

[0048] Embodiment Three:

[0049] Referring to Figures 1 - 6 , compared with Embodiment One and Embodiment Two, in this embodiment:

[0050] A first piston cylinder 28 is fixedly connected to the mounting plate 8. An air inlet pipe 38 is connected to the first piston cylinder 28. One end of the air inlet pipe 38 away from the first piston cylinder 28 is connected to the airbag 9. A first piston rod 29 is slidably connected to the first piston cylinder 28. A first piston 31 is fixedly connected to the first piston rod 29. The first piston 31 is slidably connected inside the first piston cylinder 28. When the first piston rod 29 drives the first piston 31 upward, the gas in the first piston cylinder 28 can be filled into the airbag 9 through the air inlet pipe 38. One end of the first piston rod 29 is fixedly connected to the pulling block 27, and the first piston rod 29 can drive the pulling block 27 to move up and down.

[0051] The cleaning assembly is used to clean the oil and debris on the grasping assembly. The cleaning assembly consists of an airbag 9, a solenoid valve 26, two outlet pipes 19, and a nozzle 20. The airbag 9 is fixedly installed on the mounting plate 8 for storing the air in the first piston cylinder 28. The solenoid valve 26 is fixedly installed below the airbag 9. Through the solenoid valve 26, the air in the airbag 9 can be ejected. The two outlet pipes 19 are fixedly installed on the solenoid valve 26. The nozzle 20 is connected to one end of the two outlet pipes 19. The gas in the airbag 9 can be ejected from the nozzle 20 through the outlet pipes 19 to blow off the oil and iron filings on the grasping assembly.

[0052] Two storage components are used to store the parts to be processed. Each storage component consists of four slide rails 6, a storage box 3 and four springs 4. The four slide rails 6 are respectively fixedly connected to the base 1. The storage box 3 is slidably connected to the four slide rails 6. One end of each of the four springs 4 is respectively fixedly connected to the base 1, and the other end is respectively fixedly connected to the lower part of the storage box 3 to provide a certain support for the storage box 3. Pressure sensors 39 are respectively fixedly installed under the two storage boxes 3. After the working times of the grasping component increase, a lot of machine oil, iron filings, etc. are likely to remain on the grasping component. At this time, the processed parts in the storage box 3 also increase. As a result, under the action of the gravity of the numerous processed parts, the storage box 3 drives the pressure sensor 39 downward. When the pressure sensor 39 touches the base 1, the solenoid valve 26 will be opened, and the air in the airbag 9 will be ejected to clean the grasping component.

[0053] In this embodiment, when the first piston rod 29 drives the pull block 27 upward, the first piston 31 will be pushed upward to collect air into the airbag 9. After the grasping component works multiple times, air continuously enters the airbag 9, the gas in the airbag 9 increases, and the internal air pressure also continuously increases. Moreover, a lot of machine oil, iron filings, etc. are likely to remain on the grasping component. At this time, the processed parts in the storage box 3 also increase. As a result, under the action of the gravity of the numerous processed parts, the storage box 3 drives the pressure sensor 39 downward. When the pressure sensor 39 touches the base 1, the solenoid valve 26 will be opened, and the air in the airbag 9 will be ejected to clean the grasping component, so that the impurities such as machine oil and iron filings on it are blown off.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
