[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model, and should not be construed as limiting this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the description of this utility model, it should be understood that the terminology used is for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] This utility model provides, for example Figures 1-3The illustrated industrial robot rotary gripper includes a connecting shell 1. Grippers 2 are symmetrically arranged on the top of the connecting shell 1. Each gripper 2 has a locking groove 21 on one side close to the other. A slot 11 is formed in the center of the top surface of the connecting shell 1. A horizontal bar 12 is slidably arranged inside the slot 11. A vertical bar 13 is fixedly connected to the center of the top surface of the horizontal bar 12. A first rotating rod 3 and a second rotating rod 31 are intersectingly arranged at the top of the vertical bar 13. A cleaning roller 33 is rotatably mounted on the top of both the first rotating rod 3 and the second rotating rod 31. The cleaning roller 33 makes movable contact with the inner wall of the gripper 2. In use, moving the gripper 2 causes it to open to both sides. The horizontal bar 12 inside the slot 11 moves upward, causing the vertical bar 13 to move upward. The vertical bar 13 then causes the first rotating rod 3 and the second rotating rod 31 to move upward. The first rotating rod 3 and the second rotating rod 31 cause the cleaning roller 33 to move upward. Simultaneously, the cleaning roller 33 rotates to clean the gripper 2. After the gripper 2 opens, the workpiece to be gripped can be placed inside.
[0026] It should be noted that an anti-slip pad to prevent the workpiece from sliding can be installed in the snap-fit groove 21. The anti-slip pad is existing technology and will not be described in detail here. The connecting shell 1 is installed on the device.
[0027] It should also be noted that the vertical rod 13 can be a damping spring rod. When the workpiece is placed in the snap-fit groove 21, the cooperation between the vertical rod 13 and the cleaning roller 33 can prevent the workpiece from slipping out. The damping spring rod is existing technology and will not be described in detail here.
[0028] When the gripper 2 clamps the workpiece, the first rotating rod 3 and the second rotating rod 31 move upward to drive the cleaning roller 33 to clean the inside of the gripper 2, thereby effectively removing dust, oil or other impurities that may be present inside the gripper 2. When the gripper 2 is opened to the maximum position, the cleaning roller 33 can fully contact every corner inside the gripper 2 to ensure a comprehensive cleaning effect.
[0029] The automatic cleaning function of the cleaning roller 33 ensures that the inside of the gripper 2 is always kept clean, eliminating the need for manual cleaning by stopping the machine. This reduces maintenance time and costs, avoids mechanical failures or operational delays caused by impurities, and improves production efficiency.
[0030] The clean gripper 2 reduces the impact of impurities on the workpiece, which helps maintain the cleanliness and integrity of the workpiece.
[0031] When the cleaning roller 33 is clamped normally, it can limit the workpiece and effectively prevent the workpiece from slipping out between the two grippers 2, thus improving the stability of the workpiece during handling and processing. After reaching the designated position, the grippers 2 open, and the cleaning roller 33 starts to rotate and move again, ready for the next cleaning and limiting operation.
[0032] The stable clamping force of the gripper 2 ensures that the workpiece will not produce errors due to shaking or slippage during processing, thus improving the processing accuracy and consistency of the product.
[0033] The cleaning roller 33 is elastic. The top ends of the first rotating rod 3 and the second rotating rod 31 are fixedly connected to the mounting frame 32. The cleaning roller 33 is rotatably connected to the mounting frame 32. The mounting frame 32 provides assistance for the use of the cleaning roller 33. The elastic setting of the cleaning roller 33 allows the cleaning roller 33 to fit more tightly against the inner wall of the gripper 2, ensuring better cleaning of the inner wall of the gripper 2 while avoiding damage to the workpiece.
[0034] Mounting plates 14 are fixedly connected to the top two sides of the vertical rod 13. The first rotating rod 3 and the second rotating rod 31 are rotatably connected to the two mounting plates 14. The first rotating rod 3 has an opening 35 in the middle. The second rotating rod 31 passes through the opening 35 and is rotatably connected to the first rotating rod 3. Two springs 34 are provided at the bottom of the first rotating rod 3 and the second rotating rod 31. The two ends of the springs 34 are fixedly connected to the bottom of the first rotating rod 3 and the second rotating rod 31 on the side close to each other. When the vertical rod 13 moves, it drives the mounting plates 14 to move. When the mounting plates 14 move, they drive the first rotating rod 3 and the second rotating rod 31 to move. When the gripper 2 opens, the springs 34 use their elasticity to open the bottom of the first rotating rod 3 and the second rotating rod 31. At this time, the top of the first rotating rod 3 and the second rotating rod 31 opens outward, and the cleaning roller 33 can better fit against the inner wall of the gripper 2. When the gripper 2 closes, the closing force of the gripper 2 makes the top cleaning roller 33 close. The bottom of the first rotating rod 3 and the second rotating rod 31 compresses the springs 34, which facilitates subsequent cleaning and clamping work.
[0035] The gripper 2 has a connecting groove 22 at its bottom. The two ends of the crossbar 12 are rotatably connected to the first connecting rod 4. The top of the first connecting rod 4 is rotatably connected to the second connecting rod 41. The top of the second connecting rod 41 is rotatably connected to the inside of the connecting groove 22. The middle of the second connecting rod 41 is fixedly connected to the rotating shaft 42, which is rotatably connected to the top of the slot 11. When the crossbar 12 moves, it drives the first connecting rod 4 to move. The first connecting rod 4 rotates itself. The movement of the first connecting rod 4 drives the second connecting rod 41 to rotate. The second connecting rod 41 drives the rotating shaft 42 to rotate. The rotating shaft 42 rotates at the top of the slot 11, thereby opening the gripper 2.
[0036] It should be noted that the second connecting rod 41 is shaped like the number seven, and the second connecting rods 41 on both sides are symmetrically arranged.
[0037] Two connecting shafts 44 are rotatably connected inside the connecting groove 22 and at the top of the slot 11. Two limiting rods 43 are symmetrically arranged between the two second connecting rods 41. The two ends of the limiting rods 43 are fixedly connected to the corresponding connecting shafts 44. When the gripper 2 moves, the movement of the gripper 2 drives the top connecting shaft 44 to move. The movement of the top connecting shaft 44 drives the limiting rods 43 to rotate along the bottom connecting shaft 44. The cooperation of the components plays a limiting role.
[0038] A piston rod 5 is provided at the bottom of the connecting shell 1. The top end of the piston rod 5 passes through the connecting shell 1 and is fixedly connected to the bottom surface of the crossbar 12. An electric cylinder can be installed at the bottom of the piston rod 5. When in use, the electric cylinder is turned on, and the electric cylinder drives the piston rod 5 to move, thereby completing the subsequent clamping and cleaning work. The electric cylinder is existing technology and is not shown in the figure. It will not be described in detail here.
