Description

Technical Field

[0001] This utility model relates to the field of robotic arm linkages and robotic arms, and particularly to a robotic arm linkage and robotic arm. Background Technology

[0002] The linkage of a robotic arm is an important component of its structure. It is a rigid component that connects the various joints of the robotic arm and typically has a specific shape, length, and strength to transmit motion and force. A robotic arm is an automated mechanical device that can simulate the movements of a human arm. It consists of a series of joints, linkages, actuators, and control systems, and can perform various precise movements and tasks within a predetermined space. In industrial production, the linkage of a robotic arm converts the rotational motion generated by a motor into precise linear or curvilinear motion, thereby enabling operations such as gripping, handling, and processing of workpieces.

[0003] Most robotic arm links and their components are assembled using multiple bolts. When damaged during factory use, repairs require disassembling numerous parts, resulting in low efficiency. Furthermore, most robotic arm links and their rotating connections utilize bearings, which can cause the horizontal alignment of the connecting rods to shift over time, leading to low accuracy in rotation during operation.

[0004] The existing patent (publication number: CN219213197U) discloses a connecting rod and robotic arm for automated machinery, which relates to the technical field of connecting rods and robotic arms for automated machinery. It includes a connecting rod, an assembly unit, and a clamping unit. Both the left and right ends of the connecting rod are equipped with toothed rings. This connecting rod and robotic arm for automated machinery are assembled in a modular manner. During subsequent maintenance, only two sets of bolts need to be removed, which improves maintenance efficiency. The use of multiple sets of ball bearings and ball grooves, along with the rolling of the circumferential ball bearings, ensures the stability of the horizontal rotation of the connecting rod and improves the accuracy of the connecting rod rotation during operation.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing robotic arm links are prone to accumulating dirt and impurities during use. This accumulation increases the friction between the link and surrounding components, causing the robotic arm to overcome greater resistance during movement. In assembly operations requiring high-precision motion, this increased resistance can lead to deviations in the robotic arm's movements, affecting assembly accuracy. Furthermore, most robotic arm links lack protective structures during use, and prolonged movement and contact with external objects can easily cause wear and scratches on the link surface.

[0006] To address this, a robotic arm linkage and its robotic arm are proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a robotic arm link and robotic arm thereof, which can solve the problem that existing robotic arm links are prone to the accumulation of dirt and impurities during use. The accumulated dirt and impurities will increase the friction between the link and surrounding components, causing the robotic arm to have to overcome greater resistance during movement. In assembly operations that require high-precision movement, the increased resistance can easily lead to deviations in the robotic arm's movements, affecting the accuracy of assembly. Moreover, most robotic arm links do not have protective structures during use, and long-term movement and contact with external objects can easily lead to wear and scratches on the link surface.

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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A robotic arm linkage and a robotic arm thereof, comprising a robotic arm body 1, a connecting component 4 bolted to the top of the robotic arm body 1, a connecting rod structure 5 bolted to the top of the connecting component 4, a connecting block 6 provided on the top of the connecting rod structure 5, a cleaning mechanism 2 bolted to the right side of the connecting block 6, the inner wall of the cleaning mechanism 2 contacting the surface of the connecting rod structure 5, a buffer frame 7 provided on the left side of the connecting rod structure 5, and a protective component 3 provided on the left side of the buffer frame 7;

[0030] The cleaning mechanism 2 includes a scraper 201, a connecting rod 202, and a cleaning wipe 203. The top of the cleaning wipe 203 is bolted to the bottom of the connecting rod 202, the top of the connecting rod 202 is bolted to the bottom of the scraper 201, the inner wall of the scraper 201 is in contact with the surface of the connecting rod structure 5, the inner wall of the cleaning wipe 203 is in contact with the surface of the connecting rod structure 5, and the right side of the connecting block 6 is bolted to the left side of the cleaning wipe 203.

[0031] In this embodiment: By setting up a cleaning mechanism 2, the scraper 201 is fixed to the position of the connecting rod 202, and the connecting rod 202 is fixed to the position of the cleaning wipe 203. When the connecting rod structure 5 moves like a piston, the scraper 201 will remove stubborn dust and dirt from the surface of the connecting rod structure 5. Then, the connecting rod structure 5, after being cleaned, will be cleaned by the cleaning wipe 203. The process of cleaning the connecting rod structure 5 is relatively convenient, avoiding the accumulation of dirt in the connecting rod structure 5 during use, and avoiding the need for the robotic arm to overcome greater resistance during movement. A protective component 3 is set up. During use, a buffer frame 7 is set on the left side of the connecting rod structure 5, and then the protective component 3 is set on the left side of the buffer frame 7. This facilitates the subsequent work of further protecting the connecting rod structure 5 with the protective component 3 and the buffer frame 7, avoiding the connecting rod structure 5 from bumping into external objects during use, and facilitating the protection of the connecting rod structure 5.

[0032] Specifically, such as Figure 1 , Figure 5 , Figure 6 As shown, a damping rod 8 is bolted to the right side of the protective component 3. The right side of the damping rod 8 is bolted to the left side of the buffer frame 7. A spring 9 is sleeved on the surface of the damping rod 8.

[0033] Specifically, such as Figure 1 , Figure 5 As shown, the protective component 3 includes a protective frame 301 and a fixing rod 302. The surface of the fixing rod 302 is bolted to the inner wall of the protective frame 301, and the right side of the fixing rod 302 is bolted to the left side of the damping rod 8.

[0034] Specifically, such as Figure 6 As shown, a mounting assembly 10 is bolted to the right side of the buffer frame 7, and the inner wall of the mounting assembly 10 is bolted to the surface of the connecting rod structure 5.

[0035] In this embodiment: the protective frame 301 is fixed to the position of the fixed rod 302, which facilitates the subsequent protection work by the protective frame 301 driving the fixed rod 302 to prevent external objects from hitting the connecting rod structure 5. Then, the spring 9 is sleeved on the surface of the damping rod 8, which facilitates the subsequent buffering protection work of the fixed rod 302 through the damping rod 8 and the spring 9, preventing the impact force from being directly transmitted to the connecting rod structure 5 when there is an external impact. Then, the mounting component 10 is fixed to the position of the buffer frame 7, which facilitates the subsequent stable protection work of the buffer frame 7 through the mounting component 10.

[0036] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, an annular block 11 is bolted to the surface of the connecting rod structure 5, a fixing block 12 is bolted to the left side of the annular block 11, and a fixing plate 13 is bolted to the top of the fixing block 12.

[0037] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, a fixing frame 14 is bolted to the top of the fixing plate 13, and a slider 15 is bolted to the left side of the connecting block 6. The surface of the slider 15 is inserted into the inner wall of the fixing frame 14.

[0038] In this embodiment: the fixing block 12 is fixed to the position of the fixing plate 13, and the fixing block 12 is fixed to the position of the ring block 11, so that the subsequent fixing frame 14 can be stably installed and fixed by the fixing plate 13. Then, the slider 15 is fixed to the position of the connecting block 6, so that the connecting block 6 can drive the slider 15 to insert into the inner wall of the fixing frame 14, so that the subsequent cleaning wipe 203 can perform stable cleaning.

[0039] Specifically, such as Figure 3 , Figure 4 As shown, a knob 16 is threadedly connected to the inner wall of the slider 15, and the surface of the knob 16 is movably connected to the inner wall of the fixing frame 14.

[0040] Specifically, such as Figure 1 , Figure 2 As shown, the robotic arm body 1 includes a gripping component 101, a movable component 102, and a rotating frame 103. The top of the rotating frame 103 is bolted to the bottom of the movable component 102, the top of the gripping component 101 is bolted to the top of the movable component 102, and the bottom of the connecting component 4 is bolted to the top of the rotating frame 103.

[0041] In this embodiment: By setting a knob 16, the slider 15 can be rotated on the inner wall of the fixed frame 14 and the inner wall of the slider 15 during use, which makes it easy to restrict the slider 15 to the inner wall of the fixed frame 14. By setting a gripping component 101, a movable component 102 and a rotating frame 103, it is easy to cooperate with the gripping component 101, the movable component 102 and the rotating frame 103 to facilitate gripping.

[0042] Working principle: During the use of the robotic arm body 1, a cleaning mechanism 2 is set up. During use, the scraper 201 is fixed to the position of the connecting rod 202, and the connecting rod 202 is fixed to the position of the cleaning wipe 203. When the connecting rod structure 5 moves like a piston, the scraper 201 removes stubborn dust and dirt from the surface of the connecting rod structure 5. Then, the cleaning wipe 203 cleans the connecting rod structure 5. This process is convenient and avoids dirt accumulation on the connecting rod structure 5 during use, thus reducing the need for the robotic arm to overcome greater resistance during movement. The linkage structure 5 is equipped with a protective component 3. During use, it is positioned on the left side of the linkage structure 5 via a buffer frame 7. The protective component 3 is then positioned on the left side of the buffer frame 7 to facilitate further protection of the linkage structure 5 through the protective component 3 and the buffer frame 7. This prevents the linkage structure 5 from colliding with external objects during use and enhances the protection of the linkage structure 5. The gripping component 101, the movable component 102, and the rotating frame 103 are also provided to facilitate subsequent gripping operations.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
