Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a robot grasping and sucking mechanism. Background Art

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. It can perform tasks such as operation or movement through programming and automatic control. In the process of processing some items such as tiles and glass, in order to improve work efficiency, it is necessary to use robots to move these items. It uses suction cups to form a vacuum on the items so that the items can be sucked up and grasped.

[0003] At present, the existing robots mainly use suction cups to complete the grasping and sucking operation of objects. Since the suction cups are made of rubber material, their suction force will decrease after a period of use, so the staff needs to replace the suction cups regularly. The suction cups are generally fixed by bolts. Since there are multiple groups of suction cups, the staff needs to use tools to loosen multiple groups of bolts in turn to complete the disassembly of the suction cups. The entire disassembly efficiency is relatively cumbersome. For this reason, we propose a robot grasping and sucking mechanism to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A robot grasping and suction mechanism includes a robot body 1, the top of the robot body 1 is connected to the first support rod 2 through a mounting plate 15, and the lower side of the first support rod 2 is symmetrically provided with a second support rod 4, and the interior of the second support rod 4 is clamped with two groups of sliders 5, and the interior of the two groups of sliders 5 is vertically inserted with a moving rod 6, and the bottom end of the moving rod 6 is provided with a rubber suction cup 7, the side of the moving rod 6 is connected with a connecting block 9, and the top of the connecting block 9 is connected to the slider 5 through a first spring 10, and the top of the rubber suction cup 7 is horizontally inserted with an air pipe 8. By setting the air pipe 8, the purpose of suction can be achieved. This is a prior art and will not be described in detail here.

[0023] Further, see Figure 2 It can be known that the top end of the second support rod 4 is connected with a moving block 3, and the moving block 3 is arranged as a U-shaped structure. The interior of the moving block 3 is connected to the first support rod 2 by bolts. The side of the first support rod 2 is equidistantly provided with bolt holes that are compatible with the bolts. Through the moving block 3 arranged in the U-shaped structure, the spacing of the second support rod 4 can be adjusted to adjust the lateral position of each group of rubber suction cups 7, thereby preliminarily improving the applicability of the device in the grasping and suction process.

[0024] Further, see Figure 2 It can be known that the inside of the second support rod 4 is symmetrically provided with a slideway, and the inner wall of the slideway is in contact with the outer wall of the slider 5, the side wall of the second support rod 4 is connected to the slider 5 by bolts, and the side wall of the second support rod 4 is also evenly provided with bolt holes adapted to the bolts, so that the longitudinal position of each group of rubber suction cups 7 can be adjusted, thereby further improving the applicability of the device during the grasping and suction process.

[0025] Further, see Figure 1 and Figure 2It can be known that there are two groups of mounting plates 15, wherein the upper mounting plate 15 is connected to the robot body 1, and the lower mounting plate 15 is connected to the first support rod 2, and the upper and lower groups of mounting plates 15 are connected by bolts. Through the upper and lower groups of mounting plates 15, the connection between the first support rod 2 and the robot body 1 can be achieved, so that the staff can disassemble the first support rod 2 for maintenance.

[0026] Further, see Figure 3 and Figure 4 It can be known that a slot 12 is provided at the bottom end of the movable rod 6, and a second spring 13 is distributed inside the slot 12, and both ends of the second spring 13 are connected to a clamping block 14. The upper side of the rubber suction cup 7 is symmetrically connected to a first connecting plate 11, and a clamping groove matched with the clamping block 14 is provided inside the first connecting plate 11. Through the mutual cooperation of the second spring 13 and the clamping block 14, the rubber suction cup 7 can be quickly disassembled.

[0027] Further, see Figure 4 It can be seen that the longitudinal section of the block 14 is set as a T-shaped structure, and the inner side of the block 14 is in contact with the inner wall of the slot 12. The block 14 with a T-shaped structure can ensure the stability of its inner side during the sliding process inside the slot 12, so as to effectively prevent the second spring 13 from being skewed, thereby ensuring the service life of the second spring 13.

[0028] Further, see Figure 2 and Figure 3 It can be seen that a disc is connected to the top of the moving rod 6, and the diameter of the disc is larger than the diameter of the moving rod 6. The disc with a larger diameter can limit the top of the moving rod 6 to effectively prevent the moving rod 6 from being completely pulled out from the inside of the slider 5.

[0029] Working principle: When the utility model is in use, the staff can first install the robot body 1 at a suitable position, and then according to the specifications of the workpiece, manually push the moving block 3 set at the top of the second support rod 4 to adjust the lateral position of the rubber suction cup 7. After pushing the moving block 3 to a suitable position, the staff can use bolts to fix the moving block 3 to the side of the first support rod 2, and then the staff can push the slider 5 inserted in the slideway of the second support rod 4, so as to change the longitudinal position of the rubber suction cup 7. Then the staff can use bolts to fix the slider 5 inside the second support rod 4 again. After the adjustment is completed, the staff can use the robot body 1 to complete the grabbing of the object;

[0030] When the rubber suction cup 7 is close to the object, the rubber suction cup 7 is forced to drive the movable rod 6 connected above it to slide inside the slider 5, and the first spring 10 connected to the top of the connecting block 9 is forced to undergo elastic deformation, so as to buffer and absorb the impact force when the rubber suction cup 7 contacts the object, so as to prevent the rubber suction cup 7 from directly contacting the object. After using it for a period of time, the staff only needs to press the two groups of card blocks 14 to compress the second spring 13 and embed it into the groove 12. At this time, the staff can pull the rubber suction cup 7 downwards to complete the disassembly operation of the rubber suction cup 7. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
