Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision devices for industrial robot testing, and in particular to an anti-collision device for industrial robot testing. Background Technology

[0002] In modern industrial production, industrial robots are widely used in various fields due to their high precision, high efficiency, and high repeatability. However, comprehensive and rigorous testing is crucial to ensuring the stable performance and reliability of industrial robots before they are put into actual production. During testing, collisions with surrounding equipment, obstacles, and even their own components frequently occur due to various factors such as robot trajectory debugging, program errors, and sensor malfunctions. Once a collision occurs, it not only damages the robot's mechanical structure, such as causing joint deformation and damage to transmission components, affecting its subsequent working accuracy and service life, but it can also lead to safety accidents, threatening the personal safety of testing personnel, and causing test interruptions, increasing testing costs and time.

[0003] Existing anti-collision devices for industrial robots have many shortcomings in testing scenarios. Some devices offer limited protection, while others are complex in structure, difficult to install and debug, and not convenient for flexible application in testing environments. They can only provide simple physical blocking and cannot monitor collisions in real time and make timely adjustments. Therefore, there is an urgent need for an anti-collision device for industrial robot testing that can efficiently buffer collision impacts, is easy to install, and has multiple functions to meet the growing safety protection needs during industrial robot testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-collision device for industrial robot testing, which solves the problems that some devices have limited protective effects, some devices have complex structures, are difficult to install and debug, are not convenient to be flexibly applied in the testing environment, can only play a simple physical blocking role, and cannot monitor the collision situation in real time and make timely adjustments.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-collision device for industrial robot testing, comprising a protective shell, an electrically controlled push rod fixedly installed on the top of the inner wall of the protective shell, a connecting base plate fixedly connected to the bottom of the electrically controlled push rod, a damper fixedly installed in the middle section of the bottom of the connecting base plate, a telescopic rod fixedly connected to the outer wall of the damper, a clamping plate fixedly connected to the outer end of the telescopic rod, a sliding rod fixedly connected to the outer end of the clamping plate, a connecting slider slidably connected to the outer wall of the sliding rod, a connecting spring sleeved on the outer wall of the sliding rod, a sliding plate fixedly connected to the top of the clamping plate, a connecting rod slidably connected to the inner wall of the sliding plate, and a limit spring sleeved on the outer wall of the inner side of the connecting rod.

[0006] A further improvement is that a spring rod is fixedly connected to the bottom of the damper, and a suction cup is fixedly connected to the bottom of the spring rod. The suction cup is used to adhere to the top of the industrial robot. When the industrial robot is in test operation, it is adhered to the top of the industrial robot by the suction cup at the bottom of the spring rod, realizing a stable connection between the device and the robot. The elastic ring at the bottom of the protective shell and the anti-collision pads on its outer wall, when the robot makes initial contact with external objects, the elastic ring and the anti-collision pads use their own elastic deformation to initially buffer the impact force generated by the collision and reduce the transmission of collision energy.

[0007] A further improvement is that an elastic ring is fixedly connected to the bottom of the protective shell, and an anti-collision pad is fixedly connected to the outer wall of the elastic ring. If the impact force continues to increase, the electronically controlled push rod at the top of the inner wall of the protective shell will respond according to a preset program or a signal fed back by a sensor. The electronically controlled push rod pushes the connecting base plate downward, and the damper in the middle of the bottom of the connecting base plate moves accordingly. The damper further absorbs and consumes the impact force through its internal damping medium and structure, reducing the severity of the collision.

[0008] A further improvement is that the anti-collision pad is circumferentially arranged on the outer wall of the elastic ring; when the robot makes initial contact with an external object, the elastic ring at the bottom of the protective shell and the anti-collision pad on its outer wall use their own elastic deformation to initially buffer the impact force generated by the collision and reduce the transmission of collision energy.

[0009] A further improvement is that a mounting plate is fixedly connected to the top of the protective shell, and a monitoring camera is fixedly mounted on the top of the mounting plate; the telescopic rod on the outer wall of the damper extends outward under the action of impact force, driving the clamping plate to move outward; the slide rod at the outer end of the clamping plate slides in the connecting slider, the connecting spring is compressed, and the elastic potential energy of the spring is used to further buffer the impact force.

[0010] A further improvement is that a limiting groove is formed at the bottom of the connecting base plate, and the limiting groove is circumferentially arranged. The connecting rod is fixedly connected to the inner wall of the limiting groove, and the sliding plate is slidably connected to the inner wall of the limiting groove. The limiting groove formed at the bottom of the connecting base plate cooperates with the connecting rod and the sliding plate to provide stable guidance and limiting for the sliding of the sliding plate, ensuring that the movement of each component is accurate and reliable during the collision process, and ensuring that the entire anti-collision device can function efficiently and stably.

[0011] A further improvement is that the connecting slider is slidably connected to the inner wall of the protective shell; the monitoring camera on the top mounting plate of the protective shell can monitor the operating status and surrounding environment of the industrial robot in real time during the testing process. Once a potential collision hazard is detected, it can be promptly fed back to the control system so that the operation of the robot can be adjusted to prevent collision accidents.

[0012] By employing the above technical solution, this utility model provides an anti-collision device for industrial robot testing, which has at least the following beneficial effects:

[0013] 1. This utility model utilizes the initial buffering effect of elastic rings and anti-collision pads, combined with the synergistic effect of components such as dampers, telescopic rods, connecting springs, and limit springs, to form a multi-level buffer structure. When an industrial robot collides, it can absorb and dissipate collision energy at different stages and in different ways, effectively reducing the damage of impact force to the robot. Compared with traditional single protective devices, it greatly improves the protective effect, ensures the integrity of the robot's mechanical structure and working accuracy, and extends its service life.

[0014] 2. This utility model device not only has physical protection functions, but also integrates a monitoring camera, which can monitor the operating status of the industrial robot and the surrounding environment in real time. Once a collision risk is detected, it can promptly feed back a signal to the control system, adjust the robot's operating status in advance, and prevent collision accidents from occurring. The suction cup design enables convenient installation of the device and the robot without complicated debugging. Compared with existing anti-collision devices with complex structures and single functions, it has significantly improved in terms of functional diversity and installation convenience, meeting the needs of efficient and safe protection during industrial robot testing.

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.

[0023] Some devices offer limited protection, while others are complex in structure, difficult to install and debug, and not easily applicable in testing environments. They only provide simple physical blocking and cannot monitor collisions in real time or make timely adjustments. This embodiment provides an anti-collision device for industrial robot testing. Please refer to... Figures 1-4 An embodiment provides an anti-collision device for industrial robot testing, including a protective shell 1. An electrically controlled push rod 2 is fixedly installed on the top of the inner wall of the protective shell 1. A connecting base plate 3 is fixedly connected to the bottom of the electrically controlled push rod 2. A damper 4 is fixedly installed in the middle of the bottom of the connecting base plate 3.

A connecting rod 13 is slidably connected to the inner wall of the sliding plate 12. A limit spring 14 is sleeved on the outer wall of the inner side of the connecting rod 13. A spring rod 5 is fixedly connected to the bottom of the damper 4, and a suction cup 6 is fixedly connected to the bottom of the spring rod 5. The suction cup 6 is used to adhere to the top of the industrial robot. An elastic ring 15 is fixedly connected to the bottom of the protective shell 1, and an anti-collision pad 16 is fixedly connected to the outer wall of the elastic ring 15. The anti-collision pad 16 is circumferentially arranged on the outer wall of the elastic ring 15. A mounting plate 17 is fixedly connected to the top of the protective shell 1, and a monitoring camera 18 is fixedly installed on the top of the mounting plate 17. A limiting groove is opened at the bottom of the connecting base plate 3, and the limiting groove is circumferentially arranged. The connecting rod 13 is fixedly connected to the inner wall of the limiting groove, and the sliding plate 12 is slidably connected to the inner wall of the limiting groove. The connecting slider 11 is slidably connected to the inner wall of the protective shell 1.

[0024] Working principle: During the test operation of the industrial robot, the suction cup 6 at the bottom of the spring rod 5 is attached to the top of the industrial robot to achieve a stable connection between the device and the robot; the elastic ring 15 at the bottom of the protective shell 1 and the anti-collision pad 16 on its outer wall, when the robot makes initial contact with external objects, the elastic ring 15 and the anti-collision pad 16 use their own elastic deformation to initially buffer the impact force generated by the collision and reduce the transmission of collision energy.

[0025] If the impact force continues to increase, the electronically controlled push rod 2 at the top of the inner wall of the protective shell 1 will respond according to the preset program or the signal fed back by the sensor; the electronically controlled push rod 2 pushes the connecting base plate 3 downward, and the damper 4 in the middle of the bottom of the connecting base plate 3 moves accordingly; the damper 4 further absorbs and consumes the impact force through the internal damping medium and structure, reducing the severity of the collision.

[0026] The telescopic rod 7 on the outer wall of the damper 4 extends outward under the impact force, causing the clamping plate 8 to move outward; the slide rod 9 at the outer end of the clamping plate 8 slides in the connecting slider 11, and the connecting spring 10 is compressed, using the elastic potential energy of the spring to further buffer the impact force; the sliding plate 12 at the top of the clamping plate 8 slides on the connecting rod 13, and the limiting spring 14 is also compressed, providing a limiting and buffering effect for the movement of the clamping plate 8, so that the clamping plate 8 can better adapt to the force situation during the collision and evenly distribute the impact force;

[0027] The monitoring camera 18 on the top mounting plate 17 of the protective shell 1 can monitor the operating status and surrounding environment of the industrial robot in real time during the test. Once a potential collision hazard is detected, it can be promptly fed back to the control system so that the robot's operation can be adjusted to prevent collision accidents. The limiting groove at the bottom of the connecting base plate 3 cooperates with the connecting rod 13 and the sliding plate 12 to provide stable guidance and limit for the sliding plate 12, ensuring that the movement of each component is accurate and reliable during the collision process, and ensuring that the entire anti-collision device can function efficiently and stably.
