Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically to a collision avoidance and buffer mechanism for a gantry robot. Background Technology

[0002] Gantry robots, as crucial equipment in automated production, are widely used in industries such as automotive manufacturing, machining, and electronic assembly due to their high speed, high precision, and large load capacity. However, in complex industrial environments, gantry robots may collide with surrounding equipment, workpieces, or other robots during high-speed operation due to programming errors, sensor malfunctions, workpiece position deviations, or human error.

[0003] Based on the above, the inventors have discovered the following problems: the current anti-collision buffer mechanism for gantry robots is difficult to adapt to robotic arms of different diameters during use, and most of them are installed by bolts, which is cumbersome to disassemble and assemble, affecting the user's use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a gantry robot anti-collision buffer mechanism in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a collision avoidance and buffer mechanism for gantry robots, so as to solve the problems mentioned in the background art, that the current collision avoidance and buffer mechanisms for gantry robots are difficult to adapt to robotic arms of different diameters, and most of them are installed by bolts, which are cumbersome to install and disassemble, affecting the user's use.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A collision avoidance and buffer mechanism for a gantry robot includes a pair of clamping plates. A pair of spring telescopic rods are installed on opposite sides of each clamping plate. A connecting plate is installed at one end of each spring telescopic rod. A protective cover is provided on the end face of the connecting plate away from the clamping plates. A buffer mechanism is installed inside the protective cover. One end of the buffer mechanism is fixedly connected to the end face of the connecting plate away from the clamping plates. Connecting seats are installed on both sides of the top and bottom of one of the clamping plates. A threaded rod is provided inside the connecting seat. Insertion seats are installed on both sides of the top and bottom of the other clamping plate. One end of the threaded rod passes through the inside of the insertion seat. A rotating shaft is sleeved on one end of the threaded rod. A tightening rod is rotatably connected to the outside of the rotating shaft. An adjusting nut is installed on the other end of the threaded rod.

[0008] Furthermore, the buffer mechanism includes a damper, a buffer spring is sleeved on the outer side of the damper, a first limiting plate is installed at one end of the damper, a second limiting plate is installed at the other end of the damper, one end face of the first limiting plate is fixedly connected to the connecting plate at the end face away from the clamping plate, one end of the second limiting plate is fixedly connected to the inner side of the protective cover, one end of the buffer spring is fixedly connected to the inner side of the first limiting plate, and the other end of the buffer spring is fixedly connected to the inner side of the second limiting plate.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the damper and the buffer spring in the buffer mechanism, the buffer spring uses elastic deformation to quickly absorb the collision force, the damper slows down the spring rebound speed, and avoids the rebound force causing secondary impact on the robot. The first limit plate and the second limit plate fix the two ends of the damper and the buffer spring respectively to prevent the components from shifting, ensure the stability of the buffer structure, and improve the reliability of the collision buffer.

[0010] Furthermore, touch buttons are installed on opposite sides of each pair of clamping plates.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the touch buttons on opposite sides of a pair of clamping plates, when a collision occurs, the clamping plates or protective covers are pressed and triggered by the force to send a signal to the gantry robot control system in a timely manner, control the robot to stop in an emergency, avoid the collision from causing greater damage, realize safety warning and protection after the collision, and improve the safety of use.

[0012] Furthermore, one side of the adjusting nut and the connecting seat are in contact on the side away from the plug-in seat.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by adjusting one side of the nut and contacting the side of the connector away from the plug, pressure can be applied to the connector when the adjusting nut is tightened, which drives the clamping plate to move in opposite directions, ensuring that the clamping plate fits tightly against the robot parts, preventing the mechanism from loosening during robot operation, and ensuring installation stability.

[0014] Furthermore, a slot is provided on one side of the connector, and the outer side of the threaded rod and the inner side of the slot are engaged and connected.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by engaging the slot on one side of the plug-in seat with the outer side of the threaded rod, the radial movement of the threaded rod is restricted, preventing the threaded rod from shifting when subjected to force or robot vibration, ensuring the stability of the clamping plate spacing, and preventing the mechanism from loosening and affecting the anti-collision effect.

[0016] Furthermore, one end of the inner side of the slot is provided with an arc edge.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the arc edge at one end of the inner side of the slot plays a guiding role when installing the threaded rod, which makes it easy for the threaded rod to be quickly inserted into the slot without the need for precise alignment, thus simplifying the installation operation and improving the assembly efficiency of the mechanism.

[0018] Furthermore, clamping grooves are provided on adjacent sides of the clamping plate, and the clamping grooves are in the shape of a "V".

[0019] The beneficial effect of adopting the above-mentioned further solution is that, through the "V" shaped clamping grooves on the adjacent sides of the clamping plate, compared with planar clamping, the "V" shaped structure can adapt to gantry robot parts with different diameters or cross sections, increase the clamping contact area, improve the clamping friction, prevent the mechanism from slipping and shifting during robot movement, and at the same time, the "V" shape has an automatic centering effect, ensuring the accurate installation position of the mechanism and ensuring the effective performance of the anti-collision buffer function.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This gantry robot anti-collision buffer mechanism, through a pair of clamping plates in conjunction with a spring telescopic rod and a connecting plate, provides initial buffering when a collision occurs, reducing the impact force. The protective cover protects the internal buffer mechanism from damage, and the buffer mechanism further absorbs the collision energy. This double buffering effectively protects the gantry robot. The connecting seat, threaded rod, plug-in seat, and adjusting nut allow for adjustment of the clamping plate spacing, adapting to different specifications of gantry robot components. The tightening rod and rotating shaft facilitate manual tightening of the threaded rod, ensuring the mechanism is securely installed on the robot, improving adaptability and ease of installation. The system features a quick-acting mechanism where a damper and a buffer spring work together. The buffer spring rapidly absorbs the impact force through elastic deformation, while the damper slows down the spring's rebound speed, preventing secondary impacts on the robot. First and second limit plates respectively fix the ends of the damper and buffer spring, preventing component displacement, ensuring the stability of the buffer structure, and improving the reliability of the collision buffer. Touch buttons on opposite sides of a pair of gripping plates trigger when a collision occurs, sending a signal to the gantry robot control system to control the robot to stop urgently, preventing further damage from the collision. The system provides post-collision safety warnings and protection, enhancing operational safety. One side of the adjusting nut contacts the side of the connecting seat furthest from the insertion seat. Tightening the adjusting nut applies pressure to the connecting seat, causing the clamping plates to move towards each other. This ensures the clamping plates tightly fit the robot components, preventing loosening during robot operation and guaranteeing installation stability. A slot on one side of the insertion seat engages with the outer side of the threaded rod, restricting radial movement of the threaded rod and preventing it from shifting under stress or robot vibration. This ensures stable clamping plate spacing and prevents loosening that could affect the anti-collision effect. The arc edge at one end of the slot further assists in the installation of the threaded rod. The design provides guidance, facilitating the quick insertion of the threaded rod into the slot without precise alignment, simplifying installation and improving assembly efficiency. The "V"-shaped clamping slots on adjacent sides of the clamping plate, compared to planar clamping, allow the "V"-shaped structure to adapt to gantry robot components of different diameters or cross-sections, increasing the clamping contact area and friction to prevent slippage during robot movement. The "V" shape also provides automatic centering, ensuring precise installation and effective anti-collision buffering. This invention effectively adapts to robotic arms of different diameters and is relatively easy to install, making it highly practical. Attached Figure Description

[0028] Please see Figures 1-5This utility model provides a technical solution: a gantry robot anti-collision buffer mechanism, including a pair of clamping plates 1, a pair of spring telescopic rods 3 installed on opposite sides of the clamping plates 1, a connecting plate 4 installed at one end of the spring telescopic rods 3, a protective cover 5 provided on the end face of the connecting plate 4 away from the clamping plates 1, a buffer mechanism 6 installed on the inner side of the protective cover 5, one end of the buffer mechanism 6 and the connecting plate 4 are fixedly connected on the end face away from the clamping plates 1, connecting seats 7 are installed on both sides of the top and bottom of one clamping plate 1, and a threaded rod 9 is provided on the inner side of the connecting seat 7, and plug-in seats 8 are installed on both sides of the top and bottom of the other clamping plate 1, one end of the threaded rod 9 passes through the inner side of the plug-in seat 8, and one end of the threaded rod 9... The end sleeve is equipped with a rotating shaft 11, and a tightening rod 12 is rotatably connected to the outside of the rotating shaft 11. An adjusting nut 10 is installed at the other end of the threaded rod 9. Through a pair of clamping plates 1, in conjunction with the spring telescopic rod 3 and the connecting plate 4, the spring telescopic rod 3 first performs initial buffering when a collision occurs, reducing the impact force of the collision.

[0030] Please see Figures 1-5The buffer mechanism 6 includes a damper 601, with a buffer spring 604 sleeved on the outer side of the damper 601. A first limiting plate 602 is installed at one end of the damper 601, and a second limiting plate 603 is installed at the other end of the damper 601. One end face of the first limiting plate 602 is fixedly connected to the connecting plate 4 at the end face away from the clamping plate 1. One end of the second limiting plate 603 is fixedly connected to the inner side of the protective cover 5. One end of the buffer spring 604 is fixedly connected to the inner side of the first limiting plate 602, and the other end of the buffer spring 604 is fixedly connected to the inner side of the second limiting plate 603. Touch buttons 13 are installed on opposite sides of a pair of clamping plates 1. One side of the adjusting nut 10 and the connecting seat 7 are in contact at the side away from the plug-in seat 8. Through the cooperation of the damper 601 and the buffer spring 604 in the buffer mechanism 6, the buffer spring 604 quickly absorbs the impact force by utilizing elastic deformation, and the damper 601 slows down the spring's return. To prevent secondary impacts on the robot due to rebound force, the first limiting plate 602 and the second limiting plate 603 respectively fix the two ends of the damper 601 and the buffer spring 604 to prevent component displacement, ensure the stability of the buffer structure, and improve the reliability of collision buffering. When a collision occurs, the clamping plate 1 or the protective cover 5 is pressed by the touch button 13 on opposite sides of the pair of clamping plates 1, which can send a signal to the gantry robot control system in time to control the robot to stop in an emergency, avoid the collision from causing greater damage, realize safety warning and protection after the collision, and improve the safety of use. When the adjusting nut 10 is in contact with the side of the connecting seat 7 away from the plug seat 8, tightening the adjusting nut 10 can apply pressure to the connecting seat 7, drive the clamping plates 1 to move towards each other, ensure that the clamping plates 1 are tightly attached to the robot components, prevent the mechanism from loosening during robot operation, and ensure the stability of the installation.

[0031] 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.

[0032] Please see Figures 1-5A slot 801 is provided on one side of the connector 8. The outer side of the threaded rod 9 engages with the inner side of the slot 801. An arc edge 802 is provided at one end of the inner side of the slot 801. Clamping grooves 2 are provided on adjacent sides of the clamping plate 1. The clamping grooves 2 are "V" shaped. They engage with the outer side of the threaded rod 9 through the slot 801 on one side of the connector 8, restricting the radial movement of the threaded rod 9 and preventing it from shifting when subjected to force or robot vibration. This ensures the stability of the clamping plate 1 spacing and prevents the mechanism from loosening and affecting the anti-collision effect. The threaded rod 9 serves as a guide during installation, allowing it to quickly snap into the slot 801 without requiring precise alignment. This simplifies installation and improves assembly efficiency. The "V"-shaped clamping slots 2 on the adjacent sides of the clamping plate 1, compared to planar clamping, allow the "V"-shaped structure to adapt to gantry robot components of different diameters or cross-sections, increasing the clamping contact area and friction to prevent slippage during robot movement. The "V" shape also provides automatic centering, ensuring precise installation and effective anti-collision buffering.

[0033] Specifically, the working principle of this gantry robot anti-collision buffer mechanism is as follows: During use, a pair of clamping plates 1, in conjunction with spring telescopic rods 3 and connecting plates 4, provide initial buffering upon collision, reducing the impact force. A protective cover 5 protects the internal buffer mechanism 6 from damage. The buffer mechanism 6 further absorbs collision energy, effectively protecting the gantry robot with double buffering. Connecting seats 7, threaded rods 9, plug-in seats 8, and adjusting nut 10 work together to adjust the spacing of the clamping plates 1, adapting to different specifications of gantry robot components. Tightening rod 12 and rotating shaft 11 facilitate manual tightening of the threaded rod 9, ensuring the mechanism is securely installed on the robot, improving adaptability and ease of installation. In the impact mechanism 6, the damper 601 cooperates with the buffer spring 604. The buffer spring 604 absorbs the impact force quickly through elastic deformation, while the damper 601 slows down the spring's rebound speed, preventing the rebound force from causing a secondary impact on the robot. The first limiting plate 602 and the second limiting plate 603 respectively fix the two ends of the damper 601 and the buffer spring 604 to prevent component displacement, ensure the stability of the buffer structure, and improve the reliability of the collision buffer. Through the touch buttons 13 on opposite sides of a pair of clamping plates 1, when a collision occurs, the clamping plates 1 or the protective cover 5 are pressed and triggered, which can promptly send a signal to the gantry robot control system to control the robot to stop urgently and prevent the collision from continuing to cause damage. To prevent further damage and provide safety warnings and protection after a collision, thus improving safety, the adjusting nut 10 is positioned so that one side of the connecting seat 7 is in contact with the side away from the plug seat 8. Tightening the adjusting nut 10 applies pressure to the connecting seat 7, causing the clamping plates 1 to move towards each other. This ensures that the clamping plates 1 are tightly fitted to the robot parts, preventing the mechanism from loosening during robot operation and ensuring installation stability. The plug seat 8 has a slot 801 on one side that engages with the outer side of the threaded rod 9, restricting the radial movement of the threaded rod 9 and preventing it from shifting under force or robot vibration. This ensures stable spacing between the clamping plates 1 and prevents the mechanism from loosening and affecting the anti-collision effect. The inner edge of the slot 801 is also used for this purpose. 802 serves as a guide during the installation of the threaded rod 9, facilitating its quick insertion into the slot 801 without requiring precise alignment. This simplifies installation and improves assembly efficiency. The "V"-shaped clamping slots 2 on the adjacent sides of the clamping plate 1, compared to planar clamping, allow the "V"-shaped structure to adapt to gantry robot components of different diameters or cross-sections, increasing the clamping contact area and friction, preventing slippage and displacement during robot movement. The "V" shape also provides automatic centering, ensuring precise installation and effective anti-collision buffering. This invention effectively adapts to robotic arms of different diameters and is relatively easy to install, making it highly practical.
