Description

Technical Field

[0001] The utility model relates to the technical field of suction cup structures, in particular to a quick-replacement robot suction cup structure. Background Art

[0002] Robot-assisted handling and transfer is the process of using robot arms and other equipment to help people carry and transfer goods. According to the characteristics of different products, the robot arms usually use adsorption and clamping methods in the process of picking up products. Adsorption is to use vacuum suction cups or other adsorption devices to adsorb the surface of the product to achieve the purpose of handling and transfer. Clamping is to clamp the product with mechanical devices such as clamps or claws to ensure that the product will not fall or be damaged during the handling process. Both methods can effectively improve handling efficiency and reduce labor costs, and are widely used in various fields such as manufacturing and logistics industries.

[0003] Existing auxiliary transport structures usually use a robot suction cup assembly to absorb and grab materials, and control the position of the suction cup assembly and the material through a moving mechanism to achieve material handling. For example, Chinese Patent Publication No. CN211193931U discloses "an automatic material-taking manipulator suction cup device", which includes a fixed frame, a plurality of suction cups are provided at the bottom of the fixed frame, a sealing head is fixedly provided at the top center of the suction cup, a branch pipe is fixedly provided at the top of the sealing head, a soft rubber tube is provided on the side of the branch pipe, and the plurality of branch pipes are connected through the soft rubber tube, and a connecting head is fixedly provided at the top of the branch pipe; the soft rubber tube is sucked by the suction pipe, and the soft rubber tube sucks air from the plurality of branch pipes, and the branch pipe cooperates with the suction cup to suck up a plurality of objects at the same time, and the sealing head prevents air leakage. After the object is sucked, the manipulator flips the suction cup device as a whole, and the magnet block is magnetically adsorbed with the auxiliary manipulator, so that the suction cup device stably transports the object. The suction cup device is easy to adjust, and the suction cup device can suck up a plurality of objects at a time;

[0004] However, in actual use, the air pipe is connected to each suction nozzle. During maintenance and replacement, it is necessary to remove / install screws and pull / plug multiple air pipes in a narrow space, which is time-consuming and labor-intensive, and increases the difficulty of maintenance.

[0014] Furthermore, the nozzle fixing frame has an air path inside which is connected with the air pipe interface and the nozzle.

[0015] The utility model proposes a quick-change robot suction cup structure, which has the following beneficial effects:

[0022] 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.

[0023] Reference Figure 1-3 A robot suction cup structure for rapid replacement includes a suction cup fixing frame 1 and a nozzle fixing frame 2, wherein the nozzle fixing frame 2 is arranged on one side of the suction cup fixing frame 1, and the suction cup fixing frame 1 and the nozzle fixing frame 2 are connected via a fixing structure 3;

[0025] The fixing structure 3 includes a fastener 31 and a fixing assembly 32 . The fastener 31 and the fixing assembly 32 are respectively disposed on two sides of the suction cup fixing frame 1 and connected to the suction nozzle fixing frame 2 .

[0026] The fastener 31 includes a mounting plate 311 and a hook portion 312 , and the mounting plate 311 is connected to the suction cup fixing frame 1 .

[0027] In the utility model, the suction nozzle 4 is placed separately on the suction nozzle fixing frame 2, and is connected to the suction cup fixing frame 1 through the fixing structure 3, and is connected to the installed frame or machine through the suction cup fixing frame 1. When replacing, the suction nozzle fixing frame 2 is directly removed, and then the suction nozzle 4 is maintained and replaced, avoiding maintenance and replacement in a narrow space, reducing the difficulty of maintenance, and being more convenient and quick.

[0028] Furthermore, in the present embodiment, the lower end of the hook portion 312 is connected to the nozzle fixing frame 2, and a slot matching with the hook portion 312 is provided on the nozzle fixing frame 2. One end of the nozzle fixing frame 2 is fixed by the cooperation between the hook portion 312 and the slot, and the other end of the nozzle fixing frame 2 is fixed by a fixing assembly, so that the nozzle fixing frame 2 and the suction cup fixing frame 1 form an integral structure.

[0029] Furthermore, in the present embodiment, the fixing assembly 32 includes a mounting groove 321 provided on the suction cup fixing frame 1, and a movable buckle 322 is rotatably arranged in the mounting groove 321, and the lower end of the movable buckle 322 is engaged with the suction nozzle fixing frame 2. When the movable buckle 322 is separated from the suction nozzle fixing frame 2, the connection between the suction nozzle fixing frame 2 and the suction cup fixing frame 1 is not tight, and the suction nozzle fixing frame 2 can be removed for maintenance and replacement.

[0030] It should be noted that, in some embodiments, a spring 323 is fixedly provided in the installation groove 321, and the other end of the spring 323 abuts against the movable buckle 322 to prevent the movable buckle 322 from separating from the nozzle fixing frame 2 during daily use, causing the nozzle fixing frame 2 to be misplaced and fall off.

[0031] In more detail, in some embodiments, the nozzle fixing frame 2 has an air path 21 inside that is connected to the air pipe interface 5 and the nozzle 4. The air path 21 replaces the air pipe, thereby reducing air pipe joints, reducing the risk of air pressure leakage, and reducing the space occupied by the external connection air pipe; the suction cup moves up and down more smoothly, and a passage is formed by drilling holes inside the nozzle fixing frame 2 through machining to achieve the connection of the air path 21; the machined opening position is blocked with machine screws to form a closed structure.

[0032] Working mode: When working, the air pressure of the suction nozzle 4 is controlled by cooperating with the air pipe interface 5 and the air circuit 21, thereby adsorbing or releasing the object;

[0033] When maintaining and replacing the suction nozzle, the movable buckle 322 is pressed to separate the movable buckle 322 from the suction nozzle fixing frame 2. The connection between the suction nozzle fixing frame 2 and the suction cup fixing frame 1 is not tight. The suction nozzle fixing frame 2 is removed for maintenance and replacement, avoiding maintenance and replacement in a narrow space, reducing the difficulty of maintenance, and making it more convenient and quick.
