Description

Technical Field

[0001] This utility model relates to the field of robotic arm body technology, specifically a safety-protected robotic arm body. Background Technology

[0002] Robotic arms are the most widely used automated mechanical devices in the field of robotics. They can be found in fields such as industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. In the current equipment manufacturing process, robotic arms are generally used to clamp workpieces and then transfer them from one platform to another. In order to allow the mechanical gripper to adjust the vertical angle of clamping according to the specific environment when clamping workpieces, some robotic arm devices use multi-axis robotic arms.

[0003] Most existing robotic arms with protective structures are simply exposed to the elements. Prolonged exposure can easily lead to oxidation and corrosion, causing damage to the robotic arm.

[0004] To address the aforementioned technical problems, existing technologies have proposed relevant patents, such as the Chinese patent with authorization announcement number CN218857000U entitled "A Robotic Arm with a Protective Structure." This patent discloses a robotic arm with a protective structure, including a robotic claw. A connecting column is fixedly connected to the top of the robotic claw, and a protective sleeve is movably connected to the outer wall of the connecting column. Mounting blocks are fixedly connected to both ends of the top of the protective sleeve. A slot is provided on one side of the mounting block. Disassembly mechanisms are fixedly connected to both sides of the top of the connecting column. The disassembly mechanism includes limit rods fixedly connected to both sides of the top of the connecting column. A slider is slidably connected to the outer wall of the limit rod. A spring is fixedly connected to one side of the slider. A connecting block is fixedly connected to the bottom of the slider. A locking block is fixedly connected to one side of the connecting block. The inside of the slot is engaged with the locking block.

[0005] The aforementioned patent achieves the effect of fixing and removing the protective sleeve, thus protecting the robotic arm and minimizing oxidation caused by prolonged exposure. However, when the protective sleeve in the aforementioned patent protects the gripper head of the robotic arm, some operations are required to remove the protective sleeve from the robotic arm before it can be used normally, which has certain shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a safe and protective robotic arm body to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety-protected robotic arm body, comprising a robotic arm body, wherein a protective component is provided on the robotic arm body; the protective component includes a mounting cylinder mounted on the robotic arm body, a protective cylinder being provided on the mounting cylinder via a connector, an extension cylinder being rotatably connected to the protective cylinder on the side away from the mounting cylinder, a connecting frame being fixedly connected to the extension cylinder, a sealing part being provided between the connecting frame and the extension cylinder, and an unlocking part being provided between the mounting cylinder and the sealing part; during the stroke of the protective cylinder retracting into the mounting cylinder, the unlocking part drives the sealing part away from the extension cylinder.

[0008] Furthermore, the sealing part includes a protective leaf, which is slidably connected to the connecting frame via a connecting rod, and a positioning spring is provided between the connecting rod and the connecting frame, the elastic force of the positioning spring driving the two protective leaves to move closer to each other.

[0009] Furthermore, the unlocking part includes a force-bearing block fixedly connected to the connecting rod, a drive groove is provided on the force-bearing block, and a pressure rod is fixedly connected to the mounting cylinder, with the pressure rod abutting against the drive groove.

[0010] Furthermore, the connector includes an external thread on the outside of the protective cylinder and an internal thread on the inside of the mounting cylinder, with the external thread and the internal thread being threadedly connected.

[0011] Furthermore, one of the protective pages is provided with a card strip, and the other protective page is provided with a card slot that matches the card strip. When the two protective pages come into contact, the card strip is engaged in the card slot.

[0012] Furthermore, a connecting component is provided between the extension tube and the protective tube; the connecting component includes an annular strip fixedly connected to the extension tube, and an annular groove adapted to the annular strip is provided on the protective tube, and the annular strip and the annular groove are rotatably connected.

[0013] Furthermore, multiple sets of friction rings are provided on the peripheral side of the protective cylinder.

[0014] Furthermore, a limiting element is also provided between the connecting rod and the connecting frame.

[0015] Furthermore, the limiting component includes a limiting strip fixedly connected to the connecting rod, and the connecting frame has a limiting groove adapted to the limiting strip, with the limiting strip slidably connected in the limiting groove.

[0016] Furthermore, a wedge-shaped drive block is fixedly connected to the pressure rod, and the wedge-shaped drive block abuts against the drive groove.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: When the robotic arm body is not in use, it is protected by the mounting cylinder, protective cylinder, and sealing part. When the robotic arm body needs to be used, it is only necessary to drive the protective cylinder to slide into the mounting cylinder, so that the protective cylinder retracts into the mounting cylinder, thereby releasing the protective cylinder from protecting the robotic arm body. During the retraction of the protective cylinder into the mounting cylinder, the sealing part is unlocked by the unlocking part, thus preventing the sealing part from affecting the use of the robotic arm body. At this time, the restriction of the protective cylinder can be released and the sealing part can be unlocked during the sliding of the protective cylinder into the mounting cylinder, without the need for separate unlocking, resulting in better performance.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a safety protection type robotic arm body 1, including a robotic arm body 1, and a protective component is provided on the robotic arm body 1; the protective component includes a mounting cylinder 2 installed on the robotic arm body 1, a protective cylinder 3 is provided on the mounting cylinder 2 through a connector, an extension cylinder 4 is rotatably connected to the side of the protective cylinder 3 away from the mounting cylinder 2, a connecting frame 5 is fixedly connected to the extension cylinder 4, a sealing part is provided between the connecting frame 5 and the extension cylinder 4, and an unlocking part is provided between the mounting cylinder 2 and the sealing part. When the protective cylinder 3 retracts into the mounting cylinder 2, the unlocking part drives the sealing part away from the extension cylinder 4.

[0028] Specifically, the safety-protected robotic arm body 1 includes a robotic arm body 1, which is existing technology, and its structure and working principle will not be described in detail here. A protective component is provided on the robotic arm body 1 to protect it. Therefore, when the robotic arm body 1 is not in use, it is protected from corrosion, thereby extending its service life and improving its effectiveness. The protective component includes a mounting cylinder 2 installed on the robotic arm body 1. A protective cylinder 3 is connected to the mounting cylinder 2 via a connector. An extension cylinder 4 is rotatably connected to the side of the protective cylinder 3 away from the mounting cylinder 2. A connecting frame 5 is fixedly connected to the extension cylinder 4. A sealing part is provided between the connecting frame 5 and the extension cylinder 4. The protective cylinder and the mounting cylinder 2 protect the side of the robotic arm body 1, while the sealing part protects the end of the robotic arm body 1, providing even better protection. Furthermore, an unlocking part is provided between the mounting cylinder 2 and the sealing part. When the protective cylinder 3 retracts into the mounting cylinder 2, the unlocking part drives the sealing part away from the extension cylinder 4, which greatly improves the working efficiency of the robotic arm body 1. When the robotic arm body 1 is not in use, it is protected by the mounting cylinder 2, protective cylinder 3, and sealing part. When the robotic arm body 1 needs to be used, simply drive the protective cylinder 3 to slide into the mounting cylinder 2, causing the protective cylinder 3 to retract into the mounting cylinder 2. This releases the protective cylinder 3 from the robotic arm body 1, and during its retraction, the sealing part unlocks via the unlocking part. This prevents the sealing part from interfering with the use of the robotic arm body 1. The sliding motion of the protective cylinder 3 into the mounting cylinder 2 simultaneously releases the restriction of the protective cylinder 3 and unlocks the sealing part, eliminating the need for separate unlocking and improving usability.

[0029] In the embodiments provided by this utility model, the sealing part includes a protective leaf 6. The protective leaf 6 is slidably connected to the connecting frame 5 via a connecting rod 7. A positioning spring 9 is provided between the connecting rod 7 and the connecting frame 5. The elastic force of the positioning spring 9 drives the two protective leaves 6 to move closer to each other. Therefore, when there is no external force, the two protective leaves 6 move closer to each other under the restriction of the positioning spring 9, which can protect the robotic arm body 1 and improve the performance.

[0030] In the embodiments provided by this utility model, the unlocking part includes a force-bearing block 8 fixedly connected to the connecting rod 7. The force-bearing block 8 has a drive groove, and a pressure rod 10 is fixedly connected to the mounting cylinder 2, with the pressure rod 10 engaging with the drive groove. Specifically, after the pressure rod 10 unlocks the force-bearing block 8, it does not affect the normal operation of the robotic arm body 1. Therefore, during the stroke of the protective cylinder 3 retracting into the mounting cylinder 2, the cooperation between the pressure rod 10 and the drive groove drives the protective sleeves 6 away from each other, thereby avoiding affecting the normal operation of the robotic arm.

[0031] In the embodiments provided by this utility model, the connecting member includes an external thread 31 provided on the outside of the protective cylinder 3 and an internal thread 21 provided on the inside of the mounting cylinder 2. The external thread 31 and the internal thread 21 are threadedly connected. Therefore, when the protective cylinder 3 needs to retract into the mounting cylinder 2, it is only necessary to drive the protective cylinder 3 to rotate.

[0032] In the embodiments provided by this utility model, a locking strip is provided on one protective page 6, and a slot adapted to the locking strip is provided on the other protective page 6. When the two protective pages 6 come into contact, the locking strip is engaged in the slot, which further improves the sealing performance of the protective component and makes it more effective.

[0033] In the embodiments provided by this utility model, a connecting member 11 is also provided between the extension cylinder 4 and the protective cylinder 3. The connecting member 11 includes an annular strip fixedly connected to the extension cylinder 4. An annular groove adapted to the annular strip is provided on the protective cylinder 3. The annular strip and the annular groove are rotatably connected. Specifically, the cross section of the annular strip is trapezoidal. When the protective cylinder 3 slides, it will drive the extension cylinder 4 to slide together, resulting in excellent performance.

[0034] In the embodiments provided by this utility model, multiple sets of friction rings 12 are provided on the circumferential side of the protective cylinder 3, so as to better drive the protective cylinder 3 to rotate and meet the working requirements.

[0035] In the embodiments provided by this utility model, a limiting component is also provided between the connecting rod 7 and the connecting frame 5. The limiting component includes a limiting strip fixedly connected to the connecting rod 7. A limiting groove adapted to the limiting strip is provided on the connecting frame 5. The limiting strip is slidably connected in the limiting groove, thereby further improving the stability of the protective page 6 when it slides.

[0036] In the embodiments provided by this utility model, a wedge-shaped driving block is fixedly connected to the pressure rod 10. The wedge-shaped driving block abuts against the driving groove, which can drive the connecting rod 7 to slide the protective page 6 according to the working needs, and adjust the state of the protective page 6 according to the working needs. More specifically, the driving groove is a through groove. After the wedge-shaped driving block abuts against the driving groove, it will drive the protective page 6 to slide. When the protective page 6 slides to a predetermined position, the wedge-shaped driving block can pass through the driving groove to avoid motion interference.

[0037] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
