Description

Technical Field

[0001] This utility model relates to the field of mechanical quick-change connector technology, and in particular to a quick-change structure for robot end effector. Background Technology

[0002] The robot end effector quick-change structure, also known as the tool quick-change disc, is a core flexible connection component between the end effector of an industrial robot and various operating tools. It can significantly shorten the changeover time of multi-process operations, effectively improve the robot's operational versatility and the flexibility of the production line, and is a key piece of equipment for achieving efficient production changeover, cost reduction and efficiency improvement in industrial automation scenarios.

[0003] In related technologies, existing quick-change structures for robot end effectors mainly connect the robot-side mounting plate and the tool-side mounting plate by setting up independent rotary locking mechanisms, thereby achieving rapid switching of robot end effector tooling. However, in the process of using this quick-change structure, it is necessary to first align the robot-side mounting plate with the tool-side mounting plate, and then manually insert the locking mechanism into the two mounting plates and perform rotation and alignment operations. The operation process is relatively cumbersome, requiring simultaneous manual operation of the robot-side mounting plate and the tool-side mounting plate while performing the locking action, which presents certain operational difficulties and is not conducive to achieving the demand for efficient and rapid changeover. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a quick-change structure for robot end effector tooling. By adopting an elastic snap-fit ​​design, it realizes the quick connection and separation of the robot-side mounting plate and the tool-side mounting plate, shortens the conversion time of multi-process operations, simplifies the operation process, reduces the difficulty of operation, and improves production changeover efficiency.

[0006] To achieve the above objectives, this utility model proposes a quick-change structure for a robot end effector, including a robot-side mounting plate, a tool-side mounting plate, and a quick-change device.

[0007] In addition, the quick-change structure for the robot end effector proposed above according to this utility model may also have the following additional technical features: Specifically, the connecting assembly includes a positioning groove, a connecting plate, a mating plate, and multiple snap-fit ​​posts. The mating plate is located at the bottom of the connecting plate, the positioning groove is located in the middle of the connecting plate and extends through the bottom of the mating plate, and the multiple snap-fit ​​posts are located on the outer wall of the mating plate and are arranged in a ring around the axial direction of the mating plate.

[0008] Specifically, the limiting component includes multiple snap-fit ​​slots, a limiting plate, a quick-change rod, a mounting post, a strip groove, and a limiting seat. The multiple snap-fit ​​slots are disposed inside the limiting plate and are arranged in a ring around the axial direction of the limiting plate. The snap-fit ​​slots are inclined L-shaped. The mounting post is disposed inside the limiting seat and has a positioning post at its top. The limiting plate is located inside the limiting seat and is rotatably mounted on the mounting post. The strip groove is disposed on the outer wall of the limiting seat. The quick-change rod is disposed on the limiting plate and is slidably disposed inside the strip groove.

[0009] Specifically, the elastic component includes an upper limit block, an elastic element, and a lower limit block, wherein the elastic element is sleeved on the outside of the mounting post, and the two ends of the elastic element are respectively locked inside the upper limit block and the lower limit block.

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The quick-change structure of the robot end effector according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0016] like Figures 1-5 As shown in the figure, a quick-change structure for a robot end effector according to an embodiment of the present invention includes a robot-side mounting plate 1, a tool-side mounting plate 2, and a quick-change device, wherein the robot-side mounting plate 1 is connected to the tool-side mounting plate 2 through the quick-change device.

[0017] It should be noted that the robot-side mounting plate 1 is connected to the flange at the end of the robot by bolts, which is used to provide stable support for the entire quick-change structure. The tool-side mounting plate 2 is used to install various operating tools, such as welding guns and grippers, to meet different industrial operation needs.

[0018] The quick-change device includes a connecting component 3, a limiting component 4, and an elastic component 5. The limiting component 4 is mounted on the robot-side mounting plate 1, the connecting component 3 is mounted on the tool-side mounting plate 2, the bottom of the connecting component 3 is located inside the limiting component 4 and is engaged with the limiting component 4, and the elastic component 5 is located inside the limiting component 4.

[0019] It should be noted that the connecting component 3 and the limiting component 4 are connected by a snap-fit, which enables the robot-side mounting plate 1 and the tool-side mounting plate 2 to be quickly connected and separated, thereby shortening the conversion time of multi-process operations. The elastic component 5 can provide elastic force to the limiting component 4, ensuring that the snap-fit ​​between the connecting component 3 and the limiting component 4 is stable and reliable, and avoiding loosening or falling off of the connection due to vibration or external force.

[0020] In one embodiment of this utility model, such as Figures 3-5 As shown, the connecting component 3 includes a positioning groove 31, a connecting plate 32, a mating plate 33, and a plurality of snap-fit ​​posts 34. The mating plate 33 is located at the bottom of the connecting plate 32, the positioning groove 31 is located in the middle of the connecting plate 32 and extends through the bottom of the mating plate 33, and the plurality of snap-fit ​​posts 34 are located on the outer wall of the mating plate 33 and are distributed in a ring around the axial direction of the mating plate 33.

[0021] It should be noted that the connecting plate 32 has bolt holes and is connected to the tool side mounting plate 2 by bolts. The positioning groove 31 is cross-shaped. Through the cooperation of the snap-fit ​​post 34 and the positioning groove 31, the precise positioning and connection between the connecting component 3 and the limiting component 4 can be achieved.

[0022] In one embodiment of this utility model, such as Figure 3 As shown, the limiting assembly 4 includes multiple snap-fit ​​grooves 41, a limiting plate 42, a quick-change rod 43, a mounting post 45, a strip groove 46, and a limiting seat 47. The multiple snap-fit ​​grooves 41 are disposed inside the limiting plate 42 and are arranged in a ring around the axis of the limiting plate 42. The snap-fit ​​grooves 41 are inclined L-shaped. The mounting post 45 is disposed inside the limiting seat 47 and has a positioning post 44 on its top. The limiting plate 42 is located inside the limiting seat 47 and is rotatably mounted on the mounting post 45. The strip groove 46 is disposed on the outer wall of the limiting seat 47. The quick-change rod 43 is disposed on the limiting plate 42 and is slidably disposed inside the strip groove 46.

[0023] It should be noted that the limiting seat 47 is fixedly installed on the robot side mounting plate 1, and the limiting plate 42 is rotatably connected to the outer wall of the mounting column 45 through the bearing. The limiting plate 42 can be rotated by moving the quick-change rod 43. The rotation angle of the limiting plate 42 can be limited by the strip groove 46. The positioning column 44 is cross-shaped and its size is adapted to the size of the positioning groove 31.

[0024] Understandably, when it is necessary to connect the tool-side mounting plate 2 and the robot-side mounting plate 1, the positioning slot 31 is aligned with the positioning post 44 and inserted. At this time, the locking post 34 enters the corresponding locking slot 41. Since the locking slot 41 is inclined L-shaped, the positioning post 44 can prevent the docking plate 33 from rotating. Therefore, during the insertion process, the locking post 34 slides along the inclined L-shaped locking slot 41 and forces the limiting plate 42 to rotate around the mounting post 45. When the locking post 34 moves to the bottom of the L-shaped locking slot 41, the limiting plate 42 is reset under the push of the elastic component 5, and the locking post 34 is locked at the end of the horizontal section of the L-shaped locking slot 41. At this time, the connecting component 3 and the limiting component 4 are connected, and the robot-side mounting plate 1 and the tool-side mounting plate 2 are quickly connected.

[0025] It should be noted that the limiting plate 42 and the locking groove 41 can prevent the mating plate 33 from coming out of the limiting plate 42. The cooperation of the positioning pin 44 and the positioning groove 31 can prevent the mating plate 33 from rotating axially, thereby ensuring the stability of the connection.

[0026] In one embodiment of this utility model, such as Figures 3-4 As shown, the elastic component 5 includes an upper limit block 51, an elastic element 52, and a lower limit block 53. The elastic element 52 is sleeved on the outside of the mounting post 45, and the two ends of the elastic element 52 are respectively locked inside the upper limit block 51 and the lower limit block 53.

[0027] It should be noted that the elastic element 52 is a torsion spring, the lower limit block 53 is fixedly installed inside the limit seat 47, and the upper limit block 51 is fixedly installed at the bottom of the limit plate 42.

[0028] Understandably, when the docking plate 33 is docked with the limiting plate 42, the limiting plate 42 rotates. At this time, the elastic element 52 is compressed and undergoes elastic deformation. When the locking post 34 moves to the bottom of the L-shaped locking groove 41, the elastic element 52 recovers and pushes the limiting plate 42 to reset, thereby locking the locking groove 41 with the locking post 34 to ensure a stable connection. Through the elastic locking design, the quick-change structure can still maintain a reliable connection state when subjected to vibration or external force.

[0029] In practical applications, when it is necessary to disassemble the tool-side mounting plate 2, simply reverse the quick-change lever 43. The quick-change lever 43 drives the limiting plate 42 to rotate against the elastic force of the elastic element 52. At this time, the opening of the locking groove 41 gradually turns towards the locking post 34. When the opening of the locking groove 41 is aligned with the locking post 34, the docking plate 33 can be pulled out from the limiting plate 42, thus realizing the quick separation of the tool-side mounting plate 2 and the robot-side mounting plate 1. The entire disassembly process is simple and convenient, without complicated operations, reducing the difficulty of operation and improving work efficiency.

[0030] In summary, the quick-change structure of the robot end effector of this utility model, through the snap-fit ​​design of the connecting component and the limiting component, realizes the rapid connection and separation of the robot-side mounting plate and the tool-side mounting plate, significantly shortening the changeover time of multi-process operations. At the same time, the elastic component can provide stable elastic force for the limiting component, ensuring that the snap-fit ​​between the connecting component and the limiting component is firm and reliable, effectively avoiding loosening or detachment of the connection due to vibration or external force. Compared with the prior art, the quick-change structure disclosed in this utility model is easy to operate, requiring no complicated operation process, and can realize the rapid disassembly and replacement of the tool-side mounting plate, improving work efficiency, reducing operation difficulty, and meeting the needs of efficient production changeover.
