Description

Technical Field

[0001] This utility model belongs to the field of robot device technology, specifically a fall prevention mechanism for a robot arm. Background Technology

[0002] Robot is a common name for automated control machines. Automated control machines include all machines that simulate human behavior or thought and simulate other living beings. In a narrow sense, there are many classifications and controversies regarding the definition of a robot. Some computer programs are even called robots. In modern industry, a robot refers to an artificial machine device that can automatically perform tasks to replace or assist human work.

[0003] In the existing technology, there is a robot arm anti-fall mechanism with the publication number CN210233094U. This application can play a different degree of anti-fall effect on the robot arm by setting an auxiliary anti-fall structure. Moreover, with the dual anti-fall effect of the main anti-fall structure and the auxiliary anti-fall structure, a better anti-fall effect can be achieved, avoiding the phenomenon of robot arm falling and breaking. However, in use, the anti-falling component is usually installed and used through a clamping component, but the length of the anti-falling device cannot be quickly adjusted and precisely locked, making it difficult for the device to flexibly adapt to different sizes or dynamically changing work scenarios, reducing the overall adaptability. At the same time, the adjustment process relies on experience estimation, which is not only cumbersome and inefficient, but also prone to affecting the reliability of protection due to inaccurate positioning, posing a safety hazard. To address this, we provide an anti-falling mechanism for a robotic arm. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of rapid adjustment and precise locking of the anti-fall device length, as well as reliable fixation of the robotic arm to prevent accidental detachment, an anti-fall mechanism for a robotic arm is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A fall prevention mechanism for a robotic arm, comprising: A robotic arm, the surface of which is provided with a first anti-fall frame, the inside of which is provided with a clamping groove, the bottom of which is provided with a first stroke groove, the top of which is provided with a second stroke groove, and a circular groove provided on one side of the first anti-fall frame. The mounting and disassembly assembly is installed in a circular groove to secure the robotic arm and prevent it from falling off. The installation / removal components include: A transmission rod is set inside a circular groove. A manual turntable is fixedly installed at one end of the transmission rod. The surface of the manual turntable is provided with an anti-slip pad. A lead screw is fixedly installed at the other end of the transmission rod. One end of the lead screw is set in a first stroke groove through a bearing. A threaded block is threadedly connected to the surface of the lead screw through a threaded hole. The threaded block is partially adapted to the first stroke groove. An anti-slip clamping plate is fixedly installed at the upper end of the threaded block. The anti-slip clamping plate is provided with reinforcing ribs inside. A stroke block is fixedly installed at the upper end of the anti-slip clamping plate. The stroke block is partially adapted to a second stroke groove. Preferably, it further includes: An angle adjustment component is installed on the front of the first anti-fall frame and is used to adjust the angle of the anti-fall device synchronously with the arm. The angle adjustment component includes: A first flip plate is bolted to the front of the first anti-fall frame. A first connecting block is fixedly installed on the front of the first flip plate. A limiting hollow ring is fixedly installed on the front of the first connecting block, and a rotating groove is opened inside the limiting hollow ring.

[0006] Preferably, the limiting hollow ring has limiting holes on both sides, and a rotating ring is connected inside the limiting hole through a limiting rod. The rotating ring is partially adapted to the rotating groove.

[0007] Preferably, a second connecting block is fixedly installed on the surface of the rotating ring, and a second flip plate is fixedly installed at one end of the second connecting block.

[0008] Preferably, it further includes: An adjustment component, installed on one side of the second flip plate, is used to adjust the length of the anti-fall device; The adjustment component includes: A fixing plate is bolted to one side of the second flip plate. The fixing plate has reinforcing ribs inside. The upper and lower ends of the fixing plate have first limiting grooves. Sliders are fixedly installed on both sides of the fixing plate, and an indicator head is fixedly installed on one side of the slider. An adjustment frame is slidably connected to the surface of the slider through a sliding groove. A scale is fixedly installed on one side of the adjustment frame.

[0009] Preferably, the upper and lower ends of the adjustment frame are provided with second limiting grooves, the front of the adjustment frame is fixedly installed with a second anti-fall frame, the bottom of the first limiting groove is fixedly installed with a return spring, the return spring is provided with a telescopic rod, the upper end of the return spring is fixedly installed with an adjustment plate, and the adjustment plate is partially adapted to the first limiting groove.

[0010] Preferably, a button is fixedly installed on the upper end of the adjustment disc, and the button is partially adapted to the second limiting groove, with the upper end of the adjustment disc in contact with the lower end of the second limiting groove.

[0011] The beneficial effects of this utility model are: The adjustment component of this invention allows for easy adjustment of the anti-fall device length. When a user presses a button, a reset spring moves the adjustment disc within the first limiting groove. The adjustment disc then retracts the button into the first limiting groove, releasing the restriction on the adjustment frame. The adjustment frame is then pulled along, and the extension length is accurately determined by the indicator head and scale. When the desired length is reached, the reset spring causes the button to spring into the second limiting groove, restricting the adjustment frame. This provides rapid adjustment and precise locking of the anti-fall device length, improving the equipment's adaptability and operational efficiency in different working scenarios.

[0012] The installation and disassembly assembly of this utility model uses a manual turntable to rotate a transmission rod, which in turn drives a lead screw to rotate. The rotation of the lead screw causes a threaded block to move within the first stroke groove, which in turn moves an anti-slip clamping plate to stably clamp the robotic arm. This reliably secures the robotic arm, prevents it from accidentally falling off, and improves operational safety and stability. Attached Figure Description

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Specific implementation examples are given below.

[0017] Example 1: Please see Figures 1 to 5 This utility model provides a fall prevention mechanism for a robot arm, comprising: The robotic arm 1 has a first anti-fall frame 2 on its surface. The first anti-fall frame 2 has a clamping groove 3 inside. The bottom of the clamping groove 3 has a first stroke groove 4, and the top of the clamping groove 3 has a second stroke groove. A circular groove is provided on one side of the first anti-fall frame 2. An installation and disassembly assembly 5 is installed in the circular groove to fix the robotic arm 1 and prevent it from falling off. An angle adjustment assembly 6 is installed on the front of the first anti-fall frame 2 to adjust the angle of the anti-fall device synchronously with the arm. An adjustment assembly 7 is installed on one side of the second flip plate 608 to adjust the length of the anti-fall device.

[0018] In this embodiment, firstly, by adjusting component 7, the length of the anti-fall device is quickly adjusted and precisely locked, improving the adaptability and operational efficiency of the equipment to different working scenarios; secondly, by installing and disassembling component 5, the robotic arm 1 is reliably fixed to prevent it from accidentally falling off, thus improving operational safety and stability; then, by adjusting component 6, the anti-fall device is made adaptable to the arm's movements, effectively maintaining continuous protection while avoiding interference problems that may occur with rigid connections.

[0019] Example 2: Based on Embodiment 1, the installation and disassembly assembly 5 is further disclosed.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the installation and disassembly assembly 5 includes: A transmission rod 501 is set inside the circular groove. A manual turntable 502 is fixedly installed at one end of the transmission rod 501. The surface of the manual turntable 502 is provided with an anti-slip pad. A lead screw 503 is fixedly installed at the other end of the transmission rod 501. One end of the lead screw 503 is set in the first stroke groove 4 through a bearing. A threaded block 504 is threadedly connected to the surface of the lead screw 503 through a threaded hole. The threaded block 504 is partially adapted to the first stroke groove 4. An anti-slip clamping plate 505 is fixedly installed at the upper end of the threaded block 504. The anti-slip clamping plate 505 is provided with reinforcing ribs inside. A stroke block 506 is fixedly installed at the upper end of the anti-slip clamping plate 505. The stroke block 506 is partially adapted to the second stroke groove.

[0021] In this embodiment, rotating the manual turntable 502 drives the transmission rod 501 to rotate, which in turn drives the lead screw 503 to rotate. The rotation of the lead screw 503 drives the threaded block 504 to move within the first stroke groove 4, which in turn drives the anti-slip clamping plate 505 to move, thus stably clamping the robotic arm. This effectively secures the robotic arm 1, preventing it from accidentally falling off and improving operational safety and stability.

[0022] Example 3: Based on Embodiment 1, the angle adjustment component 6 is further disclosed.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the angle adjustment component 6 includes: A first flip plate 601 is bolted to the front of the first anti-fall frame 2. A first connecting block 602 is fixedly installed on the front of the first flip plate 601. A limiting hollow ring 603 is fixedly installed on the front of the first connecting block 602. A rotating groove is opened inside the limiting hollow ring 603. Limiting holes 604 are opened on both sides of the limiting hollow ring 603. A rotating ring 606 is connected to the inside of the limiting hole 604 through a limiting rod 605. The rotating ring 606 is partially adapted to the rotating groove. A second connecting block 607 is fixedly installed on the surface of the rotating ring 606. A second flip plate 608 is fixedly installed at one end of the second connecting block 607.

[0024] In this embodiment, when the anti-fall frame is set on the robotic arm 1, when the robotic arm flips, the rotating ring 606 rotates within the limiting hollow ring 603, causing the second flipping plate 608 to drive the anti-fall frame to flip synchronously with the robotic arm 1, thereby achieving the effect of the anti-fall device following the movement of the arm, effectively maintaining continuous protection, and avoiding interference problems that may occur due to rigid connection.

[0025] Example 4: Based on Embodiment 1, the adjustment component 7 is further disclosed.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the adjustment component 7 includes: A fixing plate 701 is bolted to one side of the second flip plate 608. The fixing plate 701 has reinforcing ribs inside. First limiting grooves 702 are formed at the upper and lower ends of the fixing plate 701. Slider blocks 703 are fixedly installed on both sides of the fixing plate 701, and an indicator head is fixedly installed on one side of each slider 703. An adjusting frame 704 is slidably connected to the surface of the slider 703 via a sliding groove. A scale 705 is fixedly installed on one side of the adjusting frame 704. Second limiting grooves 705 are formed at the upper and lower ends of the adjusting frame 704. 6. A second anti-fall frame is fixedly installed on the front of the adjustment frame 704. A return spring 707 is fixedly installed at the bottom of the first limiting groove 702. A telescopic rod is provided inside the return spring 707. An adjustment plate 708 is fixedly installed at the upper end of the return spring 707. The adjustment plate 708 is partially adapted to the first limiting groove 702. A button 709 is fixedly installed at the upper end of the adjustment plate 708. The button 709 is partially adapted to the second limiting groove 706. The upper end of the adjustment plate 708 is in contact with the lower end of the second limiting groove 706.

[0027] In this embodiment, by pressing button 709, the adjustment disc 708 moves within the first limiting groove 702 due to the reset spring 707. The adjustment disc 708 then retracts button 709 into the first limiting groove 702, releasing the restriction on the adjustment frame 704. The adjustment frame 704 is then pulled to move, and the extension length is accurately determined by the cooperation of the indicator head and the scale 705. When the length reaches the desired position, the reset spring 707 causes button 709 to spring into the second limiting groove 706, restricting the adjustment frame 704. This achieves rapid adjustment and precise locking of the anti-fall device length, improving the equipment's adaptability and operational efficiency in different working scenarios.
