Description

Technical Field

[0001] This utility model relates to the field of robot grippers, and in particular to a lever-driven passenger and cargo gripper. Background Technology

[0002] In the air passenger transport sector, visual recognition systems utilize high-resolution cameras for image acquisition and sophisticated image processing algorithms to analyze the geometry and spatial coordinates of luggage, enabling precise manipulation and grasping by robotic arms. While this technology plays a significant role in improving logistics efficiency, several technical bottlenecks have been exposed during its application. Current grasping devices exhibit limitations in adaptability to diverse luggage shapes and weight distributions. In particular, existing systems may fail to effectively grip non-standard shaped or overweight luggage, limiting their operational capabilities in complex environments. There is still room for improvement in processing speed and operational accuracy. During peak periods, robotic systems require higher computational efficiency and superior path planning algorithms to ensure rapid and accurate completion of luggage stacking tasks. Traditional grippers operate on multiple axes, which can negatively impact operational efficiency and increase maintenance costs due to the computationally intensive encoding and decoding process.

[0003] There is an urgent need in the industry to develop a modular, highly adaptable, and cost-effective mechanical gripper. This gripper should be able to handle luggage of different sizes and achieve efficiency matching through the basic structure of the gripper when the handling task intensity is high. Furthermore, the multi-axis structure should reduce the complexity of the design and avoid being placed in the gripper's execution part. This effect can be achieved by placing it inside the gripper. Utility Model Content

[0037] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0040] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0041] Example 1

[0042] Reference Figure 1 This embodiment provides a lever-driven passenger cargo gripper, including a built-in platform 100 and a linkage mechanism S. The linkage mechanism S is connected to an extension plate 101. The built-in platform 100 can be understood as an assembly of built-in components, while the linkage mechanism S is a mechanism inside the built-in platform 100 that performs the execution part. Its function is to enable the gripper to generate operating logic related to the technical solution.

[0043] Furthermore, the external platform 200 includes a main structure 200a and a load-bearing belt 200b connected thereto. The main structure 200a serves as the "skeleton" of the external platform 200, forming a shell, and also includes some parts that cooperate with the internal platform 100.

[0044] Furthermore, the extension plate 101 provides dimensional extension for the load-bearing belt 200b, which is the most important part of the technical solution, namely, providing timely expansion of the load-bearing area when dealing with irregularly shaped, oversized goods or luggage.

[0045] Example 2

[0046] Reference Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and differs from the previous embodiment in that: the linkage mechanism S includes a main shaft S1, and the main shaft S1 is rotatably connected to the main rod S2 through a ball bearing G. The main shaft S1 is the first actuating component of the entire actuating part. The two ends of the main rod S2 are respectively rotatably connected to the first auxiliary rod S3 and the second auxiliary rod S4. The operation of the main shaft S1 will transmit the power to the main rod S2, and then to the first auxiliary rod S3 and the second auxiliary rod S4, thereby completing the drive.

[0047] In detail, both the first auxiliary rod S3 and the second auxiliary rod S4 are rotatably connected to extension plates 101 at their ends. The rotation of the main shaft S1 ultimately transfers the execution effect to the extension plates 101, which serve as the primary object for expanding the bearing area. The connection between the rods here also indicates that the multi-axis structure has shifted from an external state to an internal state, and the final effect is to achieve the purpose of expanding the internal plane of the drive, which necessitates the use of a transmission structure.

[0048] In detail, the main structure 200a includes a bottom shell 200a-1, side plates 200a-2, and a slide plate 200a-3 fixedly connected between the side plates 200a-2; these components constitute the shell state of the main structure 200a.

[0049] Furthermore, the main shaft S1 is fixedly connected and placed on the support plate S5. The support plate S5 is fixedly connected to the side plate 200a-2. The support plate S5 serves as the bearing platform for the entire built-in platform 100 and the linkage mechanism S, providing support for both and being fixedly connected to the external platform 200.

[0050] Furthermore, the inner surface of the load-bearing belt 200b is provided with a guide rack 200b-1, which is engaged with the guide groove 200a-4 on the slide plate 200a-3. This can also be understood as the load-bearing belt 200b moving forward in the correct direction under the guidance of the guide rack 200b-1, and the slide plate 200a-3 providing support for the entire load-bearing belt 200b, allowing it to slide on a plane.

[0051] Furthermore, the side plates 200a-2 are rotatably connected by an electric roller 201, a driven roller 202, and a redirecting roller 203. Each of the three rollers has its own function. The electric roller 201 serves as a power source to provide power to the load-bearing belt 200b. The driven roller 202 rotates under the rotation of the electric roller 201 in the transmission relationship. The redirecting roller 203 detects the robot's turning status and presses down the load-bearing belt 200b at the rear end to achieve a taut effect.

[0052] In detail, the electric roller 201 and driven roller 202 are placed inside the load-bearing belt 200b and are engaged with the guide rack 200b-1. Therefore, the electric roller 201 and driven roller 202 are the main driving components responsible for linkage with the load-bearing belt 200b. The redirecting roller 203 is placed outside the load-bearing belt 200b, close to the slide plate 200a-3 and the electric roller 201, contacting and pressing down on the load-bearing belt 200b. This positional relationship ensures the normal operation of each roller. The use of the load-bearing belt 200b is to directly simulate the state of a passenger baggage conveyor belt on the gripper, thus allowing the gripper to directly intervene in the handling process. This greatly reduces the running motion required to handle the objects, thereby improving handling efficiency.

[0053] In detail, the pallet S5 is equipped with a positioning slide rail S5-1, and the extension plate 101 is elastically slidably connected to the positioning slide rail S5-1. The cooperation between the positioning slide rail S5-1 and the extension plate 101 ensures that the extension plate 101 can be unfolded in the normal direction of movement, expanding the entire carrying platform. The side plate 200a-2 has an opening W, the size of which is larger than that of the extension plate 101; the extension plate 101 is machined with rounded edges. The positioning slide rail S5-1 guides the extension plate 101 to move towards the opening W and form an expanded state. The rounded edges are to prevent the extension plate 101 from rubbing against each other and causing damage to the components. This flat-plate loading method and expansion mode, combined with the conveyor belt effect of the gripper, make the handling efficiency of the gripper and the luggage handling situation much more flexible, and there are no longer any restrictions on the shape and structure of the luggage.

[0054] Example 3

[0055] Reference Figure 5This is the third embodiment of the present utility model. This embodiment provides a rod-driven passenger cargo grabber. This embodiment is based on the previous embodiment, and the difference from the previous embodiment is that: a cylinder push rod 204 is provided on the side plate 200a-2, and the cylinder push rod 204 can perform a push rod output action under command.

[0056] Furthermore, the extension plate 101 is divided into plate A and plate B, with the two plates respectively placed on two auxiliary rods. This distinguishes the two extension plates with the same basic function, and also because their structure will be slightly different. This is to cooperate with the cylinder push rod 204 to form a multi-axis transmission that minimizes the movement of the extension plates 101 on both sides.

[0057] In detail, plate A has a fixed workpiece a1 that is fixedly connected to the output end of cylinder push rod 204; the first auxiliary rod S3 is used to rotatably connect with plate A, and the second auxiliary rod S4 is used to rotatably connect with plate B. The output action of cylinder push rod 204 is directed towards plate A. The main shaft S1 is located at the center line of slide plate 200a-3. Under the transmission of linkage mechanism S, the horizontal movement of plate A will drive plate B to make the same but opposite horizontal movement; the first auxiliary rod S3 and the second auxiliary rod S4 have the same length, ensuring the stability of the platform expansion effect.

[0058] In detail, the cylinder push rod 204 is conductively connected to the air supply device 204a, and the air supply device 204a provides the power source for the cylinder push rod 204. A supporting sheet metal 200a-4 is also fixedly connected to the end of the side plate 200a-2. A main body connecting flange 200a-5 is provided on the outer side of the supporting sheet metal 200a-4. The gripper is an integral part of the handling robot; however, to achieve complete multi-line handling functionality, the assistance of the robot assembly below is still required.
