Technical Field

[0001] This application relates to the field of robotics, and in particular to a gripping device for a robot and a wall panel installation robot. Background Technology

[0002] Building material board components refer to various types of material boards used in construction, decoration and other fields. Specifically, they can include autoclaved aerated concrete (ALC) partition boards, ceramsite boards, foamed ceramic boards, lightweight cement boards, wood boards, gypsum boards, aluminum alloy boards, glass boards, etc., and are commonly used in building decoration projects such as walls, floors, ceilings and exterior walls.

[0003] In the existing technology, building material board components are characterized by large size and heavy weight. Relying solely on manual installation poses problems such as danger, heavy physical labor, and low efficiency. In addition, ordinary grippers have poor gripping stability for these board components and are easily limited by the confined space at the installation site. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical solution adopted in this application is to propose a gripping device for robots and a wall panel installation robot.

[0005] The first aspect of this application provides a gripping device for a robot, comprising: a gripper, a support, a clamping member, a first drive member, and a second drive member; The first driving member and the second driving member are disposed on the clamping member; Multiple support members are arranged along the length direction of the clamping member. The first driving member connects the multiple support members through a synchronization mechanism so that the support members can extend out of the clamping member synchronously to support the plate-like component to be installed. The gripper is located on the side of the clamping member away from the support member. The second driving member drives the gripper to move towards the clamping member, thereby fixing the plate-like component to be installed from the top and bottom with the support member and clamping the plate-like component to be installed from the front and back with the clamping member.

[0006] In an optional embodiment, the gripper includes an abutment portion and a clamping portion; The second driving member drives the abutment part, which bends towards the clamping member to form a bent part.

[0007] In an optional embodiment, the length direction of the abutting portion is set at an angle of no more than 90° to the length direction of the bending portion.

[0008] In an optional embodiment, an elastic reset member is provided between the clamping portion and the bending portion.

[0010] In an optional embodiment, the synchronization mechanism includes: a slider and a guide shaft; The sliding member is provided with a plurality of mounting portions for connecting the support member; The support member is movably connected to the clamping member and the mounting part respectively through a linkage structure. The guide shaft is disposed on the clamping member, and the sliding member is disposed at the output end of the first driving member, so that the sliding member can reciprocate along the extension direction of the guide shaft, thereby driving all the support members to extend or retract synchronously.

[0011] In an optional embodiment, the support member includes a connecting part and a supporting part, and the linkage structure includes a first linkage, a second linkage and a third linkage; One end of the connecting part is movably connected to the support part, and the other end is movably connected to the first connecting rod.

[0012] In an optional embodiment, the clamping member is further provided with a positioning member located on the side of the clamping member where the gripper is located.

[0013] In an optional embodiment, the clamping member and / or the gripping member and / or the support member are provided with a cushioning pad.

[0014] The second aspect of this application provides a wall panel installation robot, including a gripping device for the robot as described in any one of the first aspects.

[0015] Beneficial effects: This application provides a gripping device for robots and a wall panel installation robot. The gripping device is used for automated handling and installation of building material panel components by robots, and can adapt to the shape characteristics of building material panel components, with good clamping stability. Specifically, the cooperation between the gripper and the clamping member can clamp the building material panel component from both front and rear directions, and the cooperation between the gripper and the support member can fix the building material panel component from both top and bottom directions. Moreover, multiple support frames can extend synchronously from the surface of the clamping member through the cooperation of the first driving member and the synchronization mechanism to stably support the panel component to be moved, so that the building material panel component is subjected to uniform force, and the panel component is clamped and fixed from multiple angles, which significantly enhances the stability of the building material panel component during handling and installation.

[0025] The terminology used in the various embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the various embodiments of this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this disclosure pertain. Terms (such as those defined in a generally used dictionary) are to be interpreted as having the same meaning as in the context of the relevant technical field and are not to be interpreted as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this disclosure.

[0026] See Figures 1 to 3 As shown, this embodiment provides a gripping device for a robot, which includes: a gripping component 1, a supporting component 2, a clamping component 3, a first driving component 4, and a second driving component 5; The first driving member 4 and the second driving member 5 are disposed on the clamping member 3; For example, the first driving component 4 and the second driving component 5 can be electric motors, pneumatic cylinders, hydraulic cylinders or stepper motors, etc. Of course, there are no restrictions on the specific implementation structure of the first driving component 4 and the second driving component 5, as long as they satisfy the driving function of gripping component 1 and supporting component 2.

[0027] Multiple support members 2 are arranged along the length direction of the clamping member 3. The first driving member 4 connects the multiple support members 2 through the synchronization mechanism 6 so that the support members 2 can extend out of the clamping member 3 synchronously to support the plate-like components to be installed. For example, panel-type components may include autoclaved aerated concrete (ALC) partition walls, ceramsite boards, foamed ceramic boards, lightweight cement boards, wood boards, gypsum boards, aluminum alloy boards, glass boards, etc. Of course, the gripping device for robots provided in this application embodiment can be applied to different panel-type components, and no limitation is made on the panel-type components.

[0028] Specifically, in some embodiments of this application, "multiple" includes two, three, or more.

[0029] The clamping component 3 can be plate-shaped, specifically a clamping plate. Of course, there are no restrictions on the specific shape of the clamping component 3, as long as it meets the clamping and fixing function.

[0030] Understandably, multiple support members 2 are arranged along the length of the clamping member 3, adapting to the shape characteristics of building panel components, providing uniform and stable support force for the panel components, forming uniform support for the panel components, thereby improving the stability of the gripping device in gripping building panel components, avoiding the problem of excessive local stress, and thus effectively reducing the warping or skewing of panel components; and the first driving member 4 connects multiple support members 2 through the synchronization mechanism 6, which can realize the synchronous extension and retraction of multiple support members 2, which can not only make the pressure distribution on the panel components more uniform, but also save the overall adjustment time of multiple support members 2, thereby improving the handling and installation efficiency of panel components.

[0031] The gripper 1 is located on the side of the clamping member 3 away from the support member 2. The second driving member 5 drives the gripper 1 to move towards the clamping member 3, fixes the plate-like component to be installed from the top and bottom with the support member 2, and clamps the plate-like component to be installed from the front and back with the clamping member 3.

[0032] Specifically, in some embodiments of this application, the connection between any two of the gripping member 1, the support member 2, the clamping member 3, the first driving member 4, and the second driving member 5 is a rotational connection, which can be achieved, for example, through a rotating shaft structure or a hinge structure. Of course, there are no restrictions on the specific connection method between the components.

[0033] Understandably, the cooperation between gripper 1 and support 2 can fix the plate-like component from the top and bottom, while the cooperation between gripper 1 and clamping component 3 can clamp the plate-like component from the front and back. Through the combined action of gripper 1, support 2, and clamping component 3, multi-directional clamping and fixing of the plate-like component is achieved, making the force on the plate-like component more even, reducing the problem of excessive local pressure, and effectively fixing the plate-like component. The plate-like component can maintain its initial position and posture during handling and installation, thereby reducing the risk of damage to the plate-like component. Furthermore, the gripper 1 is set along the side of clamping component 3 away from support 2, which can flexibly adapt to plate-like components of different sizes and thicknesses, thereby improving the versatility of the gripping device for different plate-like components.

[0034] In an optional embodiment, combined with Figures 1 to 4 As shown, the gripper 1 includes an abutment part 11 and a clamping part 13; The second driving member 5 drives the connecting part 11. The connecting part 11 bends towards the clamping member 3 to form a bent part 12. The bent part 12 is movably connected to the clamping part 13, so that the connecting part 11, driven by the second driving member 5, fixes the plate-like component to be installed from the top and bottom directions with the support member 2, and drives the clamping part 13 to cooperate with the clamping member 3 to clamp the plate-like component to be installed from the front and back directions.

[0035] Understandably, on the one hand, the abutment portion 11 bends towards the clamping member 3 to form a bent portion 12, and the bent portion 12 is movably connected to the clamping portion 13, enabling the gripper 1 to achieve fixed clamping functions in both the horizontal and vertical directions, simplifying the structural volume of the gripper 1 and improving its space utilization. On the other hand, the design of the bent portion 12 also allows the gripper 1 to better conform to the shape and size of the plate-like component during clamping, reducing the problem of slippage or loosening of the plate-like component due to uneven clamping. Furthermore, the composition of the gripper 1, including the abutment portion 11, the bent portion 12, and the clamping member 3, facilitates multi-angle fixing of the plate-like component, optimizes the fixing effect of the plate-like component, and improves the stability of the plate-like component during handling and installation.

[0036] In an optional embodiment, the length direction of the abutting portion 11 is set at an angle of no more than 90° to the length direction of the bending portion 12.

[0037] Preferably, the angle between the length direction of the contact portion 11 and the length direction of the bending portion 12 is between 50° and 89°.

[0038] Understandably, the angle range between the length direction of the abutment portion 11 and the length direction of the bending portion 12 is set in such a way that, on the one hand, the structural strength of the abutment portion 11 and the bending portion 12 can be effectively improved to extend the service life of the gripper 1; on the other hand, the presence of the bending portion 12 allows the clamping portion 13 to better match the movement path of the abutment portion 11. The angle range design can more effectively transmit the clamping force evenly to the plate-like component along the front and rear directions, making the plate-like component more evenly stressed when clamped from the front and rear, thus improving the clamping effect of the gripping device on the plate-like component.

[0039] In an optional embodiment, an elastic reset member (not shown in the figure) is provided between the clamping part 13 and the bending part 12.

[0040] For example, the elastic reset element can be a spring; however, there are no restrictions on the specific implementation structure of the elastic reset element.

[0041] Due to the tension of the elastic reset member, the degree of freedom of the clamping part 13 is controllable. When the gripper 1, in cooperation with the support member 2, clamps the first plate of multiple side-by-side plate components, the clamping part 13 will not contact the other plates, and the clamping part 13 is horizontal to the ground. When the gripper 1 is pushed, the clamping part 13 is subjected to the squeezing force of the plate components, and the clamping part 13 clamps the plate perpendicular to the ground. After assembly, the gripper 1 is released, the elastic reset member returns to its original position, and the clamping part 13 is horizontal to the ground. At the same time, the clamping part 13 improves the error tolerance of the gripping device during the material clamping process. In addition, the elastic reset member can play a certain buffering role, making the clamping part 13 clamp the plate components more stably.

[0042] In an optional embodiment, such as Figure 4 As shown, a reinforcing structure 14 is provided along the length of the gripper 1 and / or the support 2.

[0043] Specifically, in some embodiments of this application, the reinforcing structure 14 is strip-shaped or mesh-shaped, for example, it can be a reinforcing rib. Of course, there is no limitation on the specific shape of the reinforcing structure 14.

[0044] Understandably, the reinforcement structure 14 can significantly enhance the strength and rigidity of the gripping member 1 and the support member 2, and optimize the stress distribution of the gripping member 1 and the support member 2, so that the stress can be more evenly distributed and the structural load-bearing capacity of the gripping device can be improved. In particular, the reinforcement structure 14 is set along the length direction of the gripping member 1 and / or the support member 2, which can effectively improve the bending resistance and tensile resistance of the gripping member 1 and the support member 2. The reinforcement structure 14 helps to reduce the deformation of the gripping member 1 and the support member 2 when subjected to external forces, thereby enhancing the stability of the overall structure.

[0045] In an optional embodiment, combined Figure 3 , Figure 5 and Figure 6 As shown, the synchronization mechanism 6 includes: a sliding member 61 and a guide shaft 62; The sliding member 61 is provided with a plurality of mounting portions 611 for connecting the support member 2; The support member 2 is movably connected to the clamping member 3 and the mounting part 611 respectively through the linkage structure 7. The guide shaft 62 is set on the clamping member 3, and the sliding member 61 is set at the output end of the first driving member 4 so that the sliding member 61 can reciprocate along the extension direction of the guide shaft 62, driving all the support members 2 to extend or retract synchronously.

[0046] Understandably, the sliding member 61 drives the support member 2 to extend or retract synchronously, achieving consistency in the actions of multiple support members 2. This helps the gripping device to provide synchronous support when clamping or supporting plate-like components, maintaining the overall coordination and stability of the gripping device's operation. The synchronization mechanism 6 includes a guide shaft 62 and a sliding member 61. The guide shaft 62 and the sliding member 61 cooperate with each other, making the extension and retraction of the support member 2 smoother and improving the accuracy of the extension and retraction operation. Furthermore, the synchronization mechanism 6 reduces the number of first driving members 4, effectively lowering production costs and simplifying the structural design of the gripping device, saving space.

[0047] In an optional embodiment, combined with Figure 5 and Figure 6 As shown, the support member 2 includes a connecting part 21 and a support part 22, and the linkage structure 7 includes a first linkage 71, a second linkage 72 and a third linkage 73; One end of the connecting part 21 is movably connected to the support part 22, and the other end is movably connected to the first link 71. The first link 71 is movably connected to the mounting part 611. The mounting part 611 is also movably connected to the second link 72. The second link 72 is movably connected to the middle part of the connecting part 21. The third link 73 is movably connected to the mounting part 611 and is movably connected to the middle part of the second link 72.

[0048] Understandably, the cooperation of the first link 71, the second link 72, and the third link 73 enables more precise and coordinated movements, enhancing the coordination of the support 22's movement and thus improving the system accuracy and stability of the gripping device. Furthermore, the combination of the first link 71, the second link 72, and the third link 73 helps to evenly distribute the load. When the support 2 is under stress, the link structure 7 can share forces of different directions and intensities, reducing the risk of system failure. The design of the link structure 7 also makes the entire system simpler, achieving complex actions such as extension, retraction, and angle adjustment simply by controlling the first drive component 4, reducing reaction time and significantly improving work efficiency.

[0049] In an optional embodiment, such as Figures 1 to 3 As shown, the clamping member 3 is also provided with a positioning member 8, which is located on the side of the clamping member 3 where the gripping member 1 is located.

[0050] Specifically, in some embodiments of this application, two positioning elements 8 are provided and are arranged along the length direction of the clamping element 3, with each positioning element extending in a direction away from the plate surface of the clamping element 3. Of course, there are no specific limitations on the number and arrangement of the positioning elements 8; for example, three or more positioning elements 8 can be provided.

[0051] Understandably, the positioning element 8 effectively improves clamping accuracy, enabling the clamping element 3 to precisely position itself when grasping an object, avoiding instability caused by asymmetry or deviation, and enhancing the stability and reliability of the clamping process. Furthermore, it allows for quick and accurate alignment with the target when grasping an object, reducing grasping time and errors, and effectively improving overall grasping efficiency. The positioning element 8 also functions as a clamp to a certain extent; it can clamp plate-like components together with the gripping element 1 and / or the support element 2, further improving the stability of the gripping device in holding plate-like components.

[0052] In an optional embodiment, such as Figure 1 , Figures 3 to 6 As shown, a buffer pad 9 is provided on the clamping member 3 and / or the support member 2 and / or the gripping member 1.

[0053] For example, the cushioning pad 9 can be made of materials such as rubber, silicone, sponge, polyurethane, or fiber composite materials. Of course, there are no restrictions on the specific material of the cushioning pad 9.

[0054] Understandably, the buffer pad 9 reduces the impact force generated by direct contact when clamping plate-like components, effectively protecting the surface of the plate-like components from damage. Furthermore, during clamping, the buffer pad 9 effectively absorbs the impact force between the plate-like components and the clamping member 3, reducing the transmission of vibration and impact, thus keeping the clamped plate-like components stable and less susceptible to external forces. In addition, the buffer pad 9 also increases the friction between the holding member 3 and / or the support member 2 and / or the gripping member 1 and the contact surface with the plate-like components, thereby enhancing the stability of clamping and fixing the plate-like components.

[0055] This embodiment also provides a wall panel installation robot, including any of the aforementioned gripping devices for the robot, which effectively enhances the clamping stability of panel components and facilitates the handling and installation of panel components.

[0056] The embodiments of this application have at least the following beneficial effects: This application provides a gripping device for robots and a wall panel installation robot. The gripping device is used for automated handling and installation of building material panel components by robots, and can adapt to the shape characteristics of building material panel components, with good clamping stability. Specifically, the cooperation between the gripper 1 and the clamping member 3 can clamp the building material panel component from both front and rear directions, and the cooperation between the gripper 1 and the support member 2 can fix the building material panel component from both top and bottom directions. In addition, multiple support frames can extend synchronously from the surface of the clamping member 3 through the cooperation of the first driving member 4 and the synchronization mechanism 6 to stably support the panel component to be moved, so that the building material panel component is subjected to uniform force, and the panel component is clamped and fixed from multiple angles, which significantly enhances the stability of the building material panel component during handling and installation.
