[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines widely used in industrial fields. They possess a certain degree of automation and can perform various industrial processing and manufacturing functions using their own power and control capabilities. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals. Some robots are mainly used for material gripping and handling to complete assembly line processing work. However, for raw materials of different models and specifications, their sizes and shapes vary. Existing gripping devices generally use triangular chucks to grip three or four sides of the raw materials. When the raw materials are irregularly shaped, a large gripping force is required for stable gripping, which can easily damage the surrounding parts of the raw materials and affect subsequent assembly work.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0024] Example 1: As Figures 1-4 As shown, the cargo clamping device includes a mounting cylinder 01, which is rotatably connected to two rotating rings 06. Each rotating ring 06 is connected to multiple clamping components for clamping objects. The rotating rings 06 can rotate circumferentially on the mounting cylinder 01, thereby adjusting the position of the corresponding clamping components on the rotating rings 06. The multiple clamping components on the two rotating rings 06 can be adjusted separately to form multi-angle clamping, thereby adapting to the clamping of objects of different shapes. The mounting cylinder 01 is also equipped with a power component for power output. The power component drives the execution end of the clamping component to move to clamp the object. The power component generates and transmits power, thereby causing the clamping component to move and realize the clamping action. The mounting cylinder 01 is also connected to a negative pressure component that communicates with the clamping component for negative pressure adsorption clamping. The negative pressure component generates negative pressure, causing negative pressure to be generated on the contact surface between the clamping component and the object, thereby increasing the clamping force of the object, ensuring subsequent clamping and transportation, and preventing the object from falling.

[0025] In one embodiment, the clamping assembly includes a guide rod 04 fixedly connected to the rotating ring 06. Multiple guide rods 04 are provided, and the cross-section of the guide rod 04 adopts a rectangular structure. Each guide rod 04 is fitted with a sliding block 05. The bottom of the sliding block 05 is connected to a sliding sleeve 12. The bottom end of the sliding sleeve 12 is connected to an installation tube 16. The bottom end of the installation tube 16 is connected to a clamping plate 02. A threaded rod 03 that is rotatably connected to the rotating ring 06 is spirally fitted in the sliding sleeve 12. The threaded rod 03 rotates under the drive of the power assembly. At the same time, under the limitation of the sliding block 05, the sliding sleeve 12 moves, thereby driving the installation tube 16 and the clamping plate 02 to move. Multiple clamping plates 02 move towards each other to form a clamping of the object.

[0026] In one embodiment, both ends of the sliding sleeve 12 are connected to sealing components that cooperate with the threaded rod 03 for sealing between the sliding sleeve 12 and the threaded rod 03. The sealing components are existing devices, such as a rubber sleeve adapted to the thread of the threaded rod 03 or other sealing devices, thereby preventing the sliding sleeve 12 from communicating with the outside world and ensuring subsequent negative pressure suction.

[0027] In one embodiment, the guide rod 04 is hollow, and a telescopic tube 15 connected to the negative pressure component is also provided in the hollow cavity of the guide rod 04. One end of the telescopic tube 15 extends into the sliding sleeve 12 and is connected to the sliding sleeve 12. A guide groove for the movement of the telescopic tube 15 is provided at the bottom of the guide rod 04. An elastic rope connected to the guide rod 04 is connected to the telescopic tube 15. The telescopic tube 15 in the guide rod 04 is connected to the negative pressure component, so that the external gas is discharged through the clamping plate 02, the mounting tube 16, the sliding sleeve 12 and the telescopic tube 15, so that a negative pressure is generated in the clamping plate 02 to clamp the object. The elastic rope can make the telescopic tube 15 return after movement to maintain the initial position of the telescopic tube 15.

[0028] In one embodiment, the clamping plate 02 is hollow, and multiple suction nozzles 13 are connected to the clamping plate 02. One end of the suction nozzle 13 is connected to the inner cavity of the clamping plate 02. The suction nozzle 13 is made of flexible material. The suction nozzle 13 can ensure that the clamping plate 02 flexibly contacts the object and guide the airflow to ensure negative pressure suction. The clamping plate 02 is provided with holes for installing the suction nozzles 13. The number of suction nozzles 13 can be selected according to the object. The holes where no suction nozzles 13 are installed are filled with sealing plugs to prevent gas flow.

[0029] In one embodiment, a plurality of fixing plates 08 are fixedly connected to one side of the rotating ring 06. The fixing plates 08 are provided with through holes, and the mounting cylinder 01 is provided with a plurality of threaded grooves that cooperate with the through holes. The fixing plates 08 are connected to the threaded grooves by bolts installed in the through holes, so that the rotating ring 06 and the mounting cylinder 01 are relatively fixed.

[0030] The top of the mounting cylinder 01 is also connected to a mounting post 07, and the bottom of the mounting cylinder 01 is also connected to a buffer ring 14. The mounting post 07 facilitates the connection of the entire mounting cylinder 01 with other devices, enabling the disassembly and replacement of the entire device. The buffer ring 14 provides cushioning and reduces direct contact between the mounting cylinder 01 and the object.

[0031] Example 2: Figures 1-4 As shown, the difference between this embodiment and Embodiment 1 lies in the location of the power component;

[0032] The power assembly includes a conductive ring 20 fixed to the rotating ring 06. The conductive ring 20 is hollow, and a motor 19 is connected to the bottom of the conductive ring 20. The output end of the motor 19 drives a gearbox, and the output end of the gearbox is connected to a transmission tube 17 via a worm gear. The conductive ring 20 supports the motor 19. The gearbox is an existing mechanism that can change the torque. Then, through the worm gear, the torque output by the motor 19 is transmitted to the transmission tube 17, realizing the rotation of the transmission tube 17. The transmission tube 17 is located between two conductive rings 20 and passes through both conductive rings 20. A bevel gear 21 is sleeved on the outside of the transmission tube 17. The outside of the bevel gear 21 is meshed with a bevel gear 18 fixedly connected to one end of the threaded rod 03. Through the meshing between the bevel gear 21 and the bevel gear 18, the torque of the transmission tube 17 is transmitted to the threaded rod 03, driving the threaded rod 03 to rotate, realizing power supply, and thus enabling the sliding sleeve 12 to move.

[0033] Example 3: Figures 1-4 As shown, the difference between this embodiment and Embodiment 1 lies in the position of the negative pressure component;

[0034] The negative pressure assembly includes an air supply pipe connected to the conductive ring 20. The air supply pipe passes through the mounting cylinder 01 and connects to an external negative pressure device. Through the suction of the external negative pressure device, air can be drawn from the transmission pipe 17 through the air supply pipe. At the same time, through the conduction of the conductive ring 20 and the telescopic pipe 15, the external gas passes through the clamping plate 02, the mounting pipe 16, the sliding sleeve 12, the telescopic pipe 15, the conductive ring 20, the transmission pipe 17 and the air supply pipe, and is discharged through the output end of the external negative pressure device, generating negative pressure to ensure that the clamping plate 02 absorbs the object with negative pressure.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.

[0036] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
