Description

Technical Field

[0001] This utility model relates to the field of sliding devices, specifically a sliding device for a single-axis robot. Background Technology

[0002] A single-axis robot, also known as a linear module, electric slide, or single-axis manipulator, is an automated device that achieves high-precision linear motion along a single axis. Its core structure typically consists of a motor, a transmission system (ball screw, synchronous belt, or linear motor), precision guide rails, and a controller, and it is widely used in industrial automation.

[0003] Chinese Patent No. CN202223414171.8 discloses a dual-rail device for mounting an inspection robot in a modular computer room, comprising a motor, a conveyor belt, and guide rails. The output end of the motor is connected to a rotating shaft, and both ends of the rotating shaft are connected to the conveyor belt via active and passive wheels. A fixing plate is fixed to the bottom outer side of the conveyor belt. The guide rails are provided with two parallel rails located at the bottom ends of the rotating shaft. Rollers are slidably connected inside the guide rails, and sliders are rotatably connected to the outer axis of the rollers. A mounting plate is fixedly connected to the outer side of the slider, and the outer side of the mounting plate is fixedly connected to the fixing plate. A robot conveyor frame is fixed between the two mounting plates, and an inspection robot is mounted at the bottom of the robot conveyor frame.

[0004] As can be seen from the above, the photos of the cabinet dashboard taken during stable operation are of high clarity and do not require frequent shooting, which helps to improve the efficiency of backend data analysis. However, this case still has the following shortcomings: Firstly, the sliding process relies solely on the mechanical contact transmission between the lead screw and the slider, resulting in high frictional resistance. Long-term operation can easily lead to component wear, and the accuracy will decrease significantly with the use time. Secondly, the lack of auxiliary support structure means that the lead screw is prone to deformation when the robot is under heavy load, causing the sliding trajectory to deviate.

[0005] Therefore, a single-axis robot sliding device is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, such as high sliding friction and limited load capacity, this invention proposes a sliding device for a single-axis robot.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The sliding device of a single-axis robot of this utility model includes a main body, and a sliding component is provided on one side of the main body; the sliding component includes a servo motor with a self-locking function, a ball screw is fixedly installed at the output end of the servo motor, a ball nut is threaded through and installed on the ball screw, a movable plate is fixedly installed on the ball nut, a plurality of permanent magnets are fixedly installed on the top of the movable plate, and electromagnets are provided at corresponding positions of the permanent magnets to form a magnetic levitation auxiliary support system, and the electromagnets are fixedly installed on the bottom of the robot.

[0008] Preferably, the sliding assembly further includes two sliders, which are fixedly installed on both sides of the movable plate, and the two sliders are slidably mounted on slide rails.

[0009] Preferably, the sliding assembly further includes a composite sensor, which is fixedly mounted on the top of the movable plate. The composite sensor integrates a magnetic tactile sensor and a magnetic scale, and communicates with the control system.

[0010] Preferably, the main body includes a sealed chamber, and an observation window is fixedly installed on the top of the sealed chamber.

[0011] Preferably, a servo motor, a slide rail, and a bearing are sequentially fixedly installed inside the sealed chamber.

[0012] Preferably, the bearing is rotatably mounted with a ball screw.

[0013] The advantages of this utility model are: 1. This utility model, through the structural design of the sliding component, the servo motor enables the ball screw and ball nut to cooperate, combined with the magnetic levitation auxiliary support system, which not only achieves high-precision sliding transmission, but also reduces mechanical friction and wear, solving the problem of decreased accuracy and shortened lifespan caused by friction in traditional devices, while improving load capacity and operational stability. 2. This utility model achieves the dual functions of real-time position feedback and status monitoring through the integrated design of composite sensors. Combined with the rigid guidance of the slider and slide rail, it solves the problems of inaccurate positioning and lack of dynamic monitoring in traditional devices, thereby improving the intelligence level and safety reliability of the device.

[0017] 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 scope of protection of the present utility model.

[0018] Please see Figures 1-4 As shown, a single-axis robot sliding device includes a main body 1, and a sliding component 2 is provided on one side of the main body 1. The sliding component 2 includes a servo motor 21 with a self-locking function. A ball screw 22 is fixedly installed at the output end of the servo motor 21. A ball nut 23 is threaded through and threaded onto the ball screw 22. A movable plate 24 is fixedly installed on the ball nut 23. Several permanent magnets 27 are fixedly installed on the top of the movable plate 24. Electromagnets 31 are provided at corresponding positions of the permanent magnets 27 to form a magnetic levitation auxiliary support system. The electromagnets 31 are fixedly installed on the bottom of the robot 32. During operation, after the servo motor 21 starts, it drives the ball screw 22 to rotate. The ball nut 23 converts the rotational motion into linear motion, causing the movable plate 24 to move synchronously. At this time, the control system adjusts the current of the electromagnet 31, so that the permanent magnet 27 and the electromagnet 31 generate a repulsive magnetic field, forming a magnetic levitation support, reducing the pressure of the robot 32 on the movable plate 24, and reducing sliding friction. When stopping, the servo motor 21 automatically locks itself, locking the ball screw 22 to prevent the movable plate 24 from sliding accidentally.

[0019] Furthermore, the sliding assembly 2 also includes two sliders 25, which are fixedly installed on both sides of the movable plate 24, and the two sliders 25 are slidably mounted with slide rails 26 respectively. During operation, as the movable plate 24 moves, the sliders 25 on both sides slide along the slide rail 26. The rigid structure of the slide rail 26 restricts the lateral displacement of the movable plate 24, ensuring that it moves in a straight line along a single axis and improving the stability of the sliding trajectory.

[0020] Furthermore, the sliding assembly 2 also includes a composite sensor 30, which is fixedly mounted on the top of the movable plate 24. The composite sensor 30 integrates a magnetic tactile sensor 28 and a magnetic scale 29 and communicates with the control system. During operation, the magnetic scale 29 collects the position data of the movable plate 24 in real time and feeds it back to the control system to achieve precise positioning; the magnetic tactile sensor 28 detects the pressure change between the robot 32 and the movable plate 24. When the load exceeds the threshold, the control system automatically slows down or stops to avoid damage to the components.

[0021] Furthermore, the main body 1 includes a sealed chamber 11, and an observation window 12 is fixedly installed on the top of the sealed chamber 11; During operation, the sealed chamber 11 isolates external dust, moisture and other impurities, protecting the internal sliding components 2 from corrosion; the observation window 12 is made of highly transparent material, which makes it easy for operators to observe the operation status of the robot 32 and the moving plate 24 in real time, and daily monitoring can be carried out without disassembling the chamber.

[0022] Furthermore, a servo motor 21, a slide rail 26, and a bearing 33 are sequentially fixedly installed inside the sealed chamber 11. During operation, the sealed chamber 11 provides a uniform rigid mounting reference for the internal components, ensuring that the relative positions of the servo motor 21, slide rail 26 and bearing 33 are fixed, reducing the impact of vibration on transmission accuracy and improving the overall structural stability of the device.

[0023] Furthermore, a ball screw 22 is mounted through and rotatably on the bearing 33; During operation, the bearing 33 supports both ends of the ball screw 22, reducing its radial runout during rotation, reducing the meshing clearance between the screw and the ball nut 23, ensuring smooth and uninterrupted transmission, and reducing energy loss.

[0024] Working principle: After the robot 32 is placed on the movable plate 24, the control system starts the servo motor 21, which drives the ball screw 22 to rotate. The ball nut 23 drives the movable plate 24 to slide along the slide rail 26 via the slider 25. At the same time, the permanent magnet 27 and the electromagnet 31 form a magnetic levitation support to reduce friction. The composite sensor 30 provides real-time feedback of position and pressure information to achieve closed-loop control. The sealed chamber 11 protects the internal components, and the observation window 12 facilitates monitoring. When the robot stops, the servo motor 21 self-locks to ensure that the robot 32 stops stably.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
