Description

Technical Field

The former has large movement restrictions and cannot well adjust the tilt angle of the end, so it can only be used for simple handling operations.

[0003] Publication No. CN106826805B discloses a robot arm with multi-angle precise control. By replacing the end servo motor of the robot arm with a telescopic device, the telescopic device can adopt a more precise screw-type electric push rod. Since the screw-type electric push rod has strong self-locking ability, the structure has good rigidity, precise angle adjustment, high precision, and large load-bearing capacity at the end of the robotic arm, so it can be applied to application scenarios with large end loads and small installation spaces. However, the following problems still exist in the actual use of this patent:

[0004] By replacing the end servo motor of the robot arm with a telescopic device, the telescopic device can adopt a more precise screw-type electric push rod. However, when performing cleaning operations through the robot arm, because different cleaning parts are required in different places, and when installing these different cleaning parts, most of them are installed by bolts. This makes it more troublesome to replace the cleaning parts, which will increase the workload of the staff. At the same time, long-term bolt installation is also likely to cause certain damage to the robotic arm.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-5 , the present invention provides a technical solution: a multi-angle cleaning robotic arm, including a connecting plate 1 and a placing block 2, the top surface of the connecting plate 1 is fixedly connected to the placing block 2; the top surface of the placing block 2 is rotatably connected to a body 3, one side surface of the body 3 is fixedly connected to a stabilizing block 4, the side surface of the stabilizing block 4 away from the body 3 is rotatably connected to a stabilizing plate 5, the side surface of the stabilizing plate 5 away from the stabilizing block 4 is adhesively connected to a cleaning member 6, and fixing blocks 7 are symmetrically installed on both sides of the stabilizing plate 5; further including: a locking assembly 8 is arranged inside the fixing block 7; wherein, the locking assembly 8 includes a fixing rod 801 fixedly connected to the fixing block 7, the top surface of the fixing rod 801 is fixedly connected to a connecting sleeve 802, and a threaded groove 803 is opened inside the connecting sleeve 802; wherein, a clamping rod 804 is slidably connected inside the connecting sleeve 802, rubber sleeves 805 are adhesively connected to both sides of the surface of the clamping rod 804, as Figures 1-5 shown, by setting the locking assembly 8, it is more convenient to replace the cleaning member 6, thereby improving the work efficiency of the staff and reducing the damage to the body 3 at the same time.

[0030] The bottom surface of the rubber sleeve 805 is fixedly connected to the threaded groove 803, a rotating block 806 is threadedly connected to the side surface of the threaded groove 803 close to the top, the rotating block 806 is adhesively connected to the rubber sleeve 805, supporting blocks 807 are symmetrically installed on one side surface of the clamping rod 804, a movable rod 808 is rotatably connected to the top surface of the supporting block 807, a connecting block 809 is rotatably connected to one side surface of the movable rod 808, and a friction block 810 is fixedly connected to the side surface of the connecting block 809 away from the movable rod 808, as Figures 3-5As shown, when the rotating block 806 is rotated so that the rotating block 806 no longer presses the rubber sleeve 805, by rotating the clamping rod 804, the rotation of the clamping rod 804 can drive the rotation of the movable rod 808 and the friction block 810, so that a cross shape is formed between the movable rod 808 and the friction block 810 and the card slot 14, so that a clamping effect is formed between the card slot 14 and the movable rod 808 and the friction block 810. At the same time, after the clamping rod 804 is rotated, the rotating block 806 is rotated again so that the rotating block 806 presses the rubber sleeve 805. When the rubber sleeve 805 is pressed, the clamping rod 804 will be pressed, so that the clamping rod 804 can be limited, so as to ensure the convenience of installing the cleaning part 6. At the same time, it also makes it possible to increase the workload of the staff and effectively reduce the damage to the body 3. At the same time, the support block 807, the movable rod 808 and the connecting block 809 are connected by a connecting shaft, and the connecting shaft can also be tightened and loosened by bolts.

[0031] A worm 9 is rotatably connected inside the placing block 2. A worm gear 10 is meshed and connected to the back of the worm 9. The top surface of the worm gear 10 is fixedly connected to the body 3. The middle of the bottom surface of the worm gear 10 is fixedly connected with a rotating rod 11. The bottom surface of the rotating rod 11 is rotatably connected to the placing block 2. One side surface of the worm 9 is fixedly connected with a driving motor 12. The bottom surface of the driving motor 12 is fixedly connected with a support plate 13. The bottom surface of the support plate 13 is fixedly connected with the connecting plate 1. As Figure 2 shown, by starting the driving motor 12, the driving motor 12 can drive the rotation of the worm 9. By the rotation of the worm 9, the rotation of the worm gear 10 can be driven. By the rotation of the worm gear 10, the rotation of the body 3 can be driven, so that the angle of the body 3 can be adjusted. At the same time, the middle of the bottom surface of the worm gear 10 is fixedly connected with a rotating rod 11. The bottom surface of the rotating rod 11 is rotatably connected to the placing block 2, so that the worm gear 10 can be supported, and at the same time, it is ensured that the worm 9 can drive the rotation of the worm gear 10. At the same time, the driving motor 12 mainly plays a role in adjusting the angle of the body 3 through manual operation by the staff.

[0032] On one side surface of the cleaning part 6, card slots 14 are symmetrically opened. The card slots 14 are clamped and connected with the clamping rods 804, and the card slots 14 are in fit connection with the friction blocks 810. As Figure 3 shown, through the clamping connection between the card slot 14 and the clamping rod 804 and the fit connection between the card slot 14 and the friction block 810, the stable installation of the cleaning part 6 can be ensured. At the same time, when a cross shape is formed between the movable rod 808 and the friction block 810 and the card slot 14, the situation that the cleaning part 6 falls off can be avoided.

[0033] The worm 9 penetrates through the placing block 2. As Figure 2As shown, the worm gear 9 is rotatably connected to the placement block 2.

[0034] Working principle: Before using this multi-angle cleaning robotic arm, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 5 As shown, first, when installing the cleaning part 6, by rotating the rotating block 806 so that the rotating block 806 no longer squeezes the rubber sleeve 805, and then rotating the clamping rod 804, the rotation of the clamping rod 804 can drive the rotation of the movable rod 808 and the friction block 810, so that a cross shape is formed between the movable rod 808 and the friction block 810 and the card slot 14, thus forming a clamping effect between the card slot 14 and the movable rod 808 and the friction block 810. At the same time, after rotating the clamping rod 804, rotate the rotating block 806 again so that the rotating block 806 squeezes the rubber sleeve 805. Due to the rubber sleeve 805 being squeezed, the clamping rod 804 will be squeezed, so that the clamping rod 804 can be limited, ensuring the convenience of installing the cleaning part 6, and at the same time increasing the workload of the staff and effectively reducing the damage to the main body 3.

[0035] Secondly, when the angle of the main body 3 needs to be adjusted, start the driving motor 12, so that the driving motor 12 can drive the rotation of the worm gear 9. The rotation of the worm gear 9 can drive the rotation of the worm wheel 10. The rotation of the worm wheel 10 can drive the rotation of the main body 3, so that the angle of the main body 3 can be adjusted. At the same time, a rotating rod 11 is fixedly connected to the middle of the bottom surface of the worm wheel 10, and the bottom surface of the rotating rod 11 is rotatably connected to the placement block 2, so that the worm wheel 10 can be supported, and at the same time it is ensured that the worm gear 9 can drive the rotation of the worm wheel 10.
