[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-5As shown, an automatic gripping device for industrial robot processing includes a base 1. A first motor 11 is fixedly connected to the bottom end of the base 1. The output end of the first motor 11 passes through the base 1 and is fixedly connected to a mounting plate 12. An adjustment mechanism 2 is provided at the top end of the mounting plate 12. The adjustment mechanism 2 includes a fixed frame 21. A second motor 22 is fixedly connected to the top end of the fixed frame 21. A first lead screw 23 is fixedly connected to the output end of the second motor 22. One end of the first lead screw 23 is rotatably connected to the inner wall of the fixed frame 21. A first slider 24 is driven and engaged with the outer wall of the first lead screw 23. The first slider 24 is slidably connected to a groove opened on the fixed frame 21. A connecting frame 25 is fixedly connected to the side wall of the first slider 24. A drive assembly 3 is provided at the bottom end of the connecting frame 25. The drive assembly 3 includes a mounting plate 31. A gripping assembly 4 is provided at the bottom end of the mounting plate 31.

[0023] In this embodiment, the positions of the driving component 3 and the gripping component 4 can be adjusted by the adjustment mechanism 2 so that the gripping component 4 is in a suitable gripping position. Then, the gripping component 4 can be gripped by the driving component 3.

[0024] In an optional embodiment, such as Figure 3 As shown, a support rod 26 is fixedly connected to the side wall of the connecting frame 25. The support rod 26 is slidably connected to the inclined guide groove opened on the fixed frame 21. A third motor 27 is fixedly connected to the side wall of the connecting frame 25. A second lead screw 28 is fixedly connected to the output end of the third motor 27. One end of the second lead screw 28 is rotatably connected to the inner wall of the connecting frame 25. A second slider 29 is driven to the outer wall of the second lead screw 28. The top end of the second slider 29 is fixedly connected to the top end of the mounting plate 31. The second motor 22 and the third motor 27 are started by the PLC. The second motor 22 drives the first lead screw 23 to rotate, causing the first slider 24 to generate axial displacement, which drives the connecting frame 25 to move synchronously and change the height of the gripping component 4. The third motor 27 drives the second lead screw 28 to rotate, causing the second slider 29 to generate axial displacement, and the second slider 29 drives the mounting plate 31 to move synchronously.

[0025] In an optional embodiment, such as Figure 4As shown, a fourth motor 32 is fixedly connected to the inner wall of the mounting plate 31, and a turntable 33 is fixedly connected to the output end of the fourth motor 32. The turntable 33 is rotatably connected to the inner wall of the mounting plate 31. Inclined guide grooves are evenly opened on the turntable 33. A protective frame 34 is fixedly connected to the bottom end of the mounting plate 31. An image capture device 35 is installed inside the protective frame 34. The protective frame 34 is made of light-transmitting material. When the second slider 29 drives the mounting plate 31 to move synchronously, the mounting plate 31 drives the protective frame 34 and the image capture device 35 to move synchronously. The image capture device 35 captures the shape features of the object to facilitate subsequent gripping work. When the mounting plate 31 moves to a suitable position, the fourth motor 32 is started through the PLC to drive the turntable 33 to rotate.

[0026] In an optional embodiment, such as Figure 5 As shown, the gripping component 4 includes a fixed rod 41, with a guide slider 42 fixedly connected to the top of the fixed rod 41. The guide slider 42 is slidably connected to an inclined guide groove on the turntable 33, and the fixed rod 41 is slidably connected to a rectangular slide groove on the mounting plate 31. When the turntable 33 rotates, the inclined guide groove on the turntable 33 drives the guide slider 42 to slide along the rectangular slide groove, thereby driving the fixed rod 41 and the anti-slip protrusion 46 to move synchronously, so that the fixed rod 41 moves closer to the object.

[0027] In an optional embodiment, such as Figure 5 As shown, a cylinder 43 is fixedly connected to the side wall of the fixed rod 41. A movable rod 44 is rotatably connected to the end of the piston rod of the cylinder 43. A gripper 45 is rotatably connected to the end of the movable rod 44 away from the cylinder 43. The gripper 45 is rotatably connected to the bottom of the fixed rod 41. Anti-slip protrusions 46 are evenly fixedly connected to the outer wall of the gripper 45. Pressure sensors are embedded in the side wall of the fixed rod 41 that contacts the gripper and the inner wall of the gripper 45. During the gripping process, according to the shape characteristics of the object, the cylinder 43 can be started by the PLC to drive the piston rod to move, so that the piston rod drives the movable rod 44 to move, so that the movable rod 44 drives the gripper 45 to rotate. Thus, when gripping relatively regular objects, the gripper 45 can actively avoid interference during gripping. When gripping round or irregular objects, the gripper 45 can support the bottom of the object, thus ensuring the stability of the gripping and preventing the object from falling off.

[0028] In an optional embodiment, such as Figures 1-5 As shown, the first motor 11, the second motor 22, the third motor 27, the fourth motor 32, the image capture device 35, the cylinder 43, and the pressure sensor are all electrically connected through the PLC control module. The PLC controls each component and links them together to achieve the effect of automatic grasping.

[0029] The above embodiment discloses an automatic gripping device for industrial robot processing. When gripping an object, the first motor 11 is started via a PLC, driving the mounting plate 12 to synchronously rotate the fixed frame 21. This, in turn, causes the connecting frame 25, the drive assembly 3, and the gripping assembly 4 to rotate synchronously, positioning the gripping assembly 4 in the direction of the object. Then, the first motor 11, via the PLC, starts the second motor 22 and the third motor 27. The second motor 22 drives the first lead screw 23 to rotate, causing the first slider 24 to generate axial displacement, which in turn drives the connecting frame... 25 moves synchronously, changing the height of the gripping component 4; the second lead screw 28 is driven to rotate by the third motor 27, causing the second slider 29 to generate axial displacement. The second slider 29 drives the mounting plate 31 to move synchronously, and the mounting plate 31 drives the protective frame 34 and the image capture device 35 to move synchronously. The image capture device 35 captures the shape features of the object for subsequent gripping. When the mounting plate 31 moves to the appropriate position, the PLC shuts off the third motor 27, and then the PLC starts the fourth motor 32, driving the turntable 33 to rotate, so that the turntable 3... The inclined guide groove on the 3rd section drives the guide slider 42 to slide along the rectangular groove, thereby driving the fixed rod 41 and the anti-slip protrusion 46 to move synchronously, so that the fixed rod 41 moves closer to the object. During the clamping process, according to the shape characteristics of the object, the cylinder 43 can be started by the PLC to drive the piston rod to move, so that the piston rod drives the movable rod 44 to move, so that the movable rod 44 drives the gripper 45 to rotate, thereby realizing the gripping of relatively regular objects. The gripper 45 can actively avoid interference during clamping, or for round or irregular objects. During gripping, the gripper 45 can support the bottom of the object, thereby ensuring the stability of the grip and preventing the object from falling off. During the gripping process, the pressure sensors set on the fixing rod 41 and the anti-slip protrusion 46 can monitor the gripping pressure in real time to avoid damage to the object during the gripping process. In summary, the position of the drive component 3 and the gripping component 4 can be adjusted by the adjustment mechanism 2 so that the gripping component 4 is in a suitable gripping position. Then, the drive component 3 drives the gripping component 4, so that the gripping component 4 can grip the object.
