Description

Technical Field

[0001] This utility model relates to a robotic arm, specifically a magnetic quick-change robotic arm, and belongs to the field of robotic arm technology. Background Technology

[0002] A robotic arm is an automated device that can mimic the functions of a human arm and perform tasks such as precise grasping, handling, and manipulation through preset programs or external control commands. It typically consists of three main parts: an actuator, a drive mechanism, and a control system. It can be integrated into industrial robots or operate independently and is widely used in manufacturing, logistics, medical and other fields to replace manual labor in repetitive, high-intensity or dangerous environments, significantly improving production efficiency and operational accuracy.

[0003] With the advancement of technology, in order to improve factory efficiency, more and more factories are choosing to replace manual operations with mechanization, replacing manual labor with robotic arms. Faced with diversified processing needs, different products need to be produced on the same production line. Therefore, when using robotic arms for processing, it is necessary to change the robotic arms to better adapt to the processing requirements of different products. However, in the process of changing some existing robotic arms, because the connection between the robotic arm and the robotic arm is mostly fixed with bolts, disassembly cannot be completed quickly, resulting in increased disassembly time and reduced work efficiency. Therefore, a magnetic quick-change robotic arm is proposed. Utility Model Content

[0004] In view of this, the present invention provides a magnetic quick-change robotic arm to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0005] The technical solution of this utility model embodiment is implemented as follows: a magnetic quick-change robotic arm includes a robotic arm and a robotic hand, and a connecting component is provided between the robotic arm and the robotic hand;

[0006] The connecting assembly includes a connecting post, a sliding ring, a connecting sleeve, and a positioning post;

[0007] The connecting post is slidably connected to the inner wall of the connecting sleeve. A limiting groove is formed on the outer wall of the connecting post. An adsorption magnetic ring is fixedly connected to the inner wall of the limiting groove. The sliding ring is slidably connected to the outer wall of the connecting sleeve. Guide sleeves are symmetrically fixedly connected to the outer wall of the connecting sleeve. The positioning post is slidably connected to the inner wall of the guide sleeve. A limiting spring is sleeved on the outside of the connecting sleeve. A positioning magnetic ring and a limiting ring are fixedly connected to both ends of the sliding ring, respectively. A groove is formed on the outer wall of the positioning post. A return spring is sleeved on the outside of the positioning post.

[0008] More preferably, a boss is fixedly connected to the outer wall of the connecting sleeve, and the two ends of the limiting spring abut against the boss and the sliding ring respectively.

[0009] More preferably, the end of the positioning post away from the guide sleeve is spherical, and the spherical end of the positioning post is located inside the limiting groove and is attracted to the magnetic ring by magnetic force.

[0010] More preferably, the outer wall of the guide sleeve has an opening, and the position of the groove corresponds to the position of the opening.

[0011] More preferably, the limiting ring is inserted into the interior of the groove through an opening.

[0012] More preferably, one end of the return spring abuts against the end of the positioning post, and the other end of the return spring abuts against the guide sleeve.

[0013] More preferably, the connecting column is mounted on the robotic arm, and the connecting sleeve is mounted on the robotic arm.

[0014] More preferably, the shape of the connecting post is adapted to the shape of the connecting sleeve.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] When the robot arm needs to be replaced, this invention involves pulling the sliding ring to disengage the limiting ring from the groove, and then pulling the connecting post to disengage from the connecting sleeve, thus completing the disassembly of the robot arm. Next, the connecting post is inserted into the connecting sleeve, and the positioning post is inserted into the magnetic adsorption ring. Then, pulling the sliding ring separates it from the boss, causing the sliding ring to drive the limiting ring into the groove, fixing the position of the positioning post, thus completing the installation of the robot arm. Compared to existing technologies, this invention, through the combined structure of the magnetic adsorption ring, sliding ring, limiting spring, and connecting post, enables rapid installation and disassembly of the robot arm, significantly improving the ease of assembly and disassembly. It allows for quick disassembly and installation, reducing time and increasing work efficiency. Furthermore, the synergistic effect of the positioning post and limiting ring effectively limits the position of the robot arm, thereby greatly enhancing the overall structural stability.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, this utility model embodiment provides a magnetic quick-change robotic arm, including a robotic arm 31 and a robotic hand 32, with a connecting component 101 provided between the robotic arm 31 and the robotic hand 32;

[0028] The connecting assembly 101 includes a connecting post 11, a sliding ring 14, a connecting sleeve 17, and a positioning post 21;

[0029] The connecting post 11 is slidably connected to the inner wall of the connecting sleeve 17. The connecting post 11 is mounted on the robot arm 32, and the connecting sleeve 17 is mounted on the robot arm 31. The shape of the connecting post 11 is adapted to the shape of the connecting sleeve 17. The end of the connecting post 11 is square. Therefore, when the connecting post 11 is docked with the connecting sleeve 17, the connecting post 11 will not rotate axially.

[0030] A limiting groove 12 is provided on the outer side wall of the connecting column 11, and an adsorption magnetic ring 13 is fixedly connected to the inner side wall of the limiting groove 12. The shape of the adsorption magnetic ring 13 is adapted to the shape of the limiting groove 12.

[0031] The sliding ring 14 is slidably connected to the outer wall of the connecting sleeve 17. The outer wall of the connecting sleeve 17 is symmetrically and fixedly connected to the guide sleeve 19. The position of the positioning column 21 can be precisely defined by the guide sleeve 19, thereby effectively enhancing the stability of the structure.

[0032] The positioning post 21 is slidably connected to the inner wall of the guide sleeve 19. The connecting sleeve 17 is fitted with a limiting spring 15. The end of the positioning post 21 away from the guide sleeve 19 is spherical. The spherical end of the positioning post 21 is located inside the limiting groove 12 and is attracted to the magnetic ring 13 by magnetic force. Then, when the connecting post 11 is connected to the connecting sleeve 17, the magnetic ring 13 can magnetically attract the positioning post 21, and the positioning post 21 is inserted into the magnetic ring 13.

[0033] The sliding ring 14 is fixedly connected to a positioning magnetic ring 16 and a limiting ring 25 at its two ends. The outer wall of the positioning post 21 has a groove 22. A return spring 23 is sleeved on the outside of the positioning post 21. The outer wall of the connecting sleeve 17 is fixedly connected to a boss 18. The two ends of the limiting spring 15 abut against the boss 18 and the sliding ring 14 respectively. The outer wall of the guide sleeve 19 has an opening 20. The position of the groove 22 corresponds to the position of the opening 20. The limiting ring 25 is inserted into the inside of the groove 22 through the opening 20. When installing the robot arm 32, the sliding ring 14 slides along the connecting sleeve 17 under the pushing action of the limiting spring 15. The movement of the sliding ring 14 drives the limiting ring 25, so that it can be smoothly inserted into the inside of the groove 22. Under the continuous action of the limiting spring 15, the position of the limiting ring 25 is fixed. In this way, the position of the positioning post 21 can be precisely controlled through the groove 22.

[0034] Once the position of the positioning post 21 is fixed, the spherical end of the positioning post 21 is located inside the magnetic adsorption ring 13, which effectively limits the position of the connecting post 11 and prevents it from sliding out of the connecting sleeve 17, thereby significantly enhancing the stability of the overall structure.

[0035] In one embodiment, one end of the return spring 23 abuts against the end of the positioning post 21, and the other end of the return spring 23 abuts against the guide sleeve 19. When the robot arm 32 needs to be disassembled, the limiting ring 25 is first driven away from the groove 22 by the sliding ring 14. Then, the sliding ring 14 is pulled so that it is attracted to the boss 18 by the positioning magnetic ring 16, thereby fixing the position of the sliding ring 14. Then, the connecting post 11 is pulled out directly. Since the end of the positioning post 21 is designed to be spherical, the connecting post 11 can be pulled out smoothly. After being pulled out, the positioning post 21 is automatically reset under the action of the return spring 23.

[0036] When this utility model is in operation: when it is necessary to replace the robot arm 32, the robot arm 32 is first disassembled. Pull the sliding ring 14 to make the limiting ring 25 disengage from the groove 22. Then, the sliding ring 14 is attracted to the boss 18 by the positioning magnetic ring 16 to fix the position of the sliding ring 14. Next, hold the robot arm 32 and pull it out directly. The connecting post 11 disengages from the connecting sleeve 17. Since the end of the positioning post 21 is designed to be spherical, the connecting post 11 can be pulled out smoothly. At this time, the disassembly of the robot arm 32 is completed.

[0037] When the robot arm 32 needs to be installed, the connecting post 11 is inserted into the inside of the connecting sleeve 17, and the magnetic ring 13 magnetically attracts the positioning post 21. The positioning post 21 is inserted into the magnetic ring 13. Then, the sliding ring 14 is pulled to separate the sliding ring 14 from the boss 18. At this time, under the pushing action of the limiting spring 15, the sliding ring 14 drives the limiting ring 25 to insert into the inside of the groove 22, and the position of the positioning post 21 is fixed. At this time, the installation of the robot arm 32 is completed.

[0038] Compared with existing technologies, this utility model, through the combination of structures such as the magnetic adsorption ring 13, the sliding ring 14, the limiting spring 15, and the connecting column 11, enables the rapid installation and disassembly of the robot arm 32, significantly improving the ease of assembly and disassembly of the device. It can quickly complete disassembly and installation, reducing the time required for disassembly and installation and improving work efficiency. In addition, with the synergistic effect of structures such as the positioning column 21 and the limiting ring 25, the position of the robot arm 32 can be effectively limited, thereby greatly enhancing the stability of the overall structure.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
