[0002] Industrial robot teaching fixtures are tools specifically designed for education and training to help students understand the operating principles and application scenarios of industrial robots. These fixtures are typically mounted on the end effector of industrial robots and can be configured in various ways to adapt to different teaching needs, such as assembly exercises, material handling simulations, welding operations, and drawing tasks. By changing or adjusting the fixtures, instructors can set up various experimental scenarios, enabling students to learn key skills such as programming techniques, path planning, and troubleshooting through hands-on practice.

[0003] In order to maximize students' learning interest and teaching effectiveness in the classroom, drawing pens are usually installed on robot fixtures to draw various trajectories from simple to complex, including squares, circles, and even text and pictures, as teaching content for practical courses. However, due to the insufficient sensitivity of the collision detection on industrial robots, coupled with the inevitable mistakes made by students as beginners in operation and programming, the drawing pens are frequently broken or the paper is torn during practical training. Sometimes, this even causes collisions with the industrial robot, which seriously affects the progress and effectiveness of practical teaching and makes it inconvenient to use. Utility Model Content

[0032] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an industrial robot teaching fixture with anti-collision function.

[0033] like Figures 1-8As shown, this utility model discloses an industrial robot teaching fixture with anti-collision function, including an operating table 1. A movable component 2 is provided on the rear side of the operating table 1. The movable component 2 includes a threaded block 21 with an internal thread on its inner side. A robotic arm 3 is mounted on the top of the threaded block 21. A buffer component 4 is provided at the output end of the robotic arm 3. The buffer component 4 includes a sleeve 41, which is bolted to the output end of the robotic arm 3. A guide ring 42 is slidably connected to the inner cavity of the sleeve 41. Limit components 5 are provided on both the left and right sides of the top of the operating table 1. A motor 22 is mounted on the rear side of the operating table 1. The rear side of the operating table 1 is fixed. A positioning plate is connected, and the positioning plate is installed with the motor 22. A threaded rod 23 is rotatably connected to the rear side of the operating table 1. The outer surface of the threaded rod 23 has an external thread that matches the internal thread of the threaded block 21. One end of the threaded rod 23 and the output shaft of the motor 22 are respectively connected to pulleys 24, and the two pulleys 24 are connected by belt drive. The outer surface of the threaded rod 23 is threadedly connected to the inner side of the threaded block 21, and the outer surface of the threaded block 21 is slidably connected to the rear side of the operating table 1. A guide rod 25 is connected to the rear side of the operating table 1, and the outer surface of the guide rod 25 is connected to the inner side of the threaded block 21. A fixed connection is made to the rear side of the operating table 1. Two elongated plates are arranged side-by-side, with their opposite sides connected to the ends of the threaded rod 23 and the guide rod 25. The outer surfaces of the top and bottom of the sleeve 41 are each provided with a movable cavity 43. A first mounting seat 44 is provided on the outer surface of each movable cavity 43. A fixing screw 45 is threaded through the top of the first mounting seat 44 and the inner side of the bottom of the guide ring 42. The fixing screw 45 is threaded to the inner sides of the top and bottom of the guide ring 42. The area where the guide ring 42 contacts the fixing screw 45 is provided with a matching thread, thus allowing for the abutment mounting of drawing pens of different sizes using the two fixing screws 45. The outer surface of the sleeve 41... The surface is threaded with a second mounting base 46. The moving contact module 47 and the stationary contact module 48 are respectively mounted on the opposite side of the first mounting base 44 and the second mounting base 46. The moving contact module 47 and the stationary contact module 48 are electrically connected to the robotic arm 3. The stationary contact module 48 and the moving contact module 47 are preferably sensors such as force sensors, so as to facilitate the detection of the force of the drawing pen during the drawing and avoid damage to the drawing pen. The stationary contact module 48 and the moving contact module 47 are used in conjunction with the robotic arm 3. A spring 49 is fixedly connected to the rear side of the sleeve 41, and the end of the spring 49 away from the sleeve 41 is connected to the inner cavity of the sleeve 41.

[0034] like Figures 2-6As shown, the limiting component 5 includes a welding plate 51, which is fixedly connected to the top of the operating table 1. The welding plate 51 is U-shaped. Several spring dampers 52 are installed in the inner cavity of the welding plate 51. A lower pressure plate 53 is connected to the side of the spring damper 52 away from the welding plate 51. The front and rear sides of the lower pressure plate 53 are slidably connected to the inner cavity of the welding plate 51. The lower pressure plate 53 is convenient for pressing and clamping drawing paper of different thicknesses for teaching purposes. A pull rod 54 is fixedly connected to the top of the lower pressure plate 53, and the top end of the pull rod 54 extends to the outer side of the top of the welding plate 51.

[0035] Specifically, the user places the drawing pen into the guide ring 42 and then manually turns the fixing screw 45 to install the drawing pen against the surface. At this time, when the robotic arm 3 operates the drawing pen and pen tip installed in the sleeve 41 to contact the paper, the guide ring 42 will compress the spring 49. At the same time, the moving contact module 47 will also move synchronously with the guide ring 42 along the moving cavity 43. At this time, the robotic arm 3 is in a safe working state and can be operated and adjusted normally. If the operation is incorrect and the robotic arm 3 moves excessively, a collision signal will be generated when the moving contact module 47 touches the stationary contact module 48. The robotic arm 3 can use this signal to stop the robot's movement in time, thereby achieving the effect of collision prevention.

[0036] The working principle of an industrial robot teaching fixture with anti-collision function: The user starts the motor 22, which drives the pulley 24 and the threaded rod 23 to rotate. The threaded rod 23 drives the threaded block 21 to move left and right using the thread transmission principle. The threaded block 21 drives the robotic arm 3 and the buffer component 4 to move synchronously, thereby expanding the moving area of ​​the robotic arm 3 carrying the buffer component 4, and thus expanding the drawing area. Before drawing, the user can manually pull the lever 54 to move it upward. The lever 54 drives the lower pressure plate 53 to move synchronously. During the synchronous movement of the lower pressure plate 53, it squeezes the spring damper 52. Conversely, the spring damper 52 is used to reset, thereby pressing and clamping drawing papers of different thicknesses, which is convenient for subsequent drawing operations and easy to use.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
