Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning, in particular to a laser cleaning workstation for the outer wall of a thin-walled cylindrical workpiece. Background Art

[0002] In industrial manufacturing, cleaning large, thin-walled cylindrical workpieces has always been a technical challenge. Traditional cleaning methods, such as mechanical friction, chemical corrosion, or ultrasonic cleaning, are often inefficient and may damage the workpiece surface. Laser cleaning, as an emerging cleaning technology, has gradually become the preferred method for industrial cleaning due to its advantages such as high efficiency, environmental protection, and minimal damage to the workpiece. However, when applied to large, thin-walled cylindrical workpieces, laser cleaning faces the problem of how to ensure the accuracy and safety of the cleaning process.

[0003] Existing laser cleaning technology typically uses a robot equipped with a laser cleaning head to clean workpieces. While this configuration offers a certain degree of flexibility and automation, when processing large, thin-walled cylindrical workpieces, the workpiece's geometric characteristics, such as thin walls and large size, as well as the positioner's clamping accuracy, can easily lead to misalignment between the workpiece and the positioner. This misalignment can cause the workpiece to collide with the laser cleaning head during rotation, compromising cleaning effectiveness and potentially causing deformation or other damage to the workpiece, reducing the reliability and efficiency of the cleaning process. Utility Model Content

[0004] This utility model proposes an innovative laser cleaning workstation technology solution. Through a carefully designed mechanical structure, this solution aims to achieve stable and precise positioning of large thin-walled cylindrical workpieces, ensuring safe laser cleaning.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A laser cleaning workstation for the outer wall of a thin-walled cylindrical workpiece comprises a work platform and a positioner arranged below the work platform; a plurality of electric guide rails are provided on the top of the work platform, the work platform is circular, and the plurality of electric guide rails are distributed equidistantly around the work platform; a positioning block is synchronously and slidably connected to each electric guide rail, and the separated sides of the plurality of positioning blocks abut against the inner wall of the thin-walled cylindrical workpiece located on the electric guide rail.

[0007] Furthermore, the positioner includes a position servo motor fixed between the output end and the bottom of the working platform, and a base for fixing the position servo motor is provided below the position servo motor.

[0008] Furthermore, it also includes a plurality of support columns located at the bottom of the working platform, and balls movably arranged on the top ends of the support columns and rollingly connected to the bottom of the working platform.

[0009] Furthermore, an annular groove is provided at the bottom of the working platform, and the upper portion of the ball is fitted in the annular groove and rolls along the groove.

[0010] Furthermore, a plurality of the support columns are equidistantly distributed around the bottom of the working platform.

[0011] Furthermore, it also includes a laser cleaning robot, which is arranged on one side of the work platform.

[0012] Furthermore, the laser cleaning robot is provided with a laser vision tracker.

[0013] The beneficial effects of the technical solution provided by this application are:

[0014] This laser cleaning station for the outer wall of thin-walled cylindrical workpieces features equally spaced electric guide rails arranged around the top of the work platform, ensuring they are concentric with the work platform. The synchronized movement of multiple positioning blocks on the guide rails ensures that each block moves the same distance, allowing them to simultaneously engage the workpiece's inner wall, ensuring stable positioning on the positioner and concentricity with the worktable.

[0019] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Reference Figure 1-2 , a laser cleaning workstation for the outer wall of a thin-walled cylindrical workpiece, includes a work platform 10 and a positioner located underneath it; the work platform 10 is the basic part of the laser cleaning workstation, which provides a stable operating plane for the entire cleaning process. The design of the work platform 10 usually needs to take into account the load-bearing capacity, stability and coordination with the positioner to ensure that the workpiece can remain stable during the cleaning process. The positioner is located below the work platform 10, and its main function is to support and accurately control the position and posture of the work platform or workpiece. During the laser cleaning process, the positioner can rotate or tilt the workpiece to a specific angle so that the laser head can clean the workpiece from different angles.

[0021] The top of the working platform 10 is provided with a plurality of electric guide rails 20. The working platform 10 is circular, and the plurality of electric guide rails 20 are equidistantly distributed around the working platform 10; each electric guide rail 20 is synchronously slidably connected to a positioning block 21. The electric guide rails 20 are a guide rail system installed on the top of the working platform 10. They are equidistantly distributed around the working platform 10 and are used to guide the movement of the positioning blocks 21. The synchronous control of the electric guide rails 20 ensures that the positioning blocks 21 can be evenly distributed around the workpiece to achieve a uniform cleaning effect. The separated sides of the plurality of positioning blocks 21 abut against the inner wall of the thin-walled cylindrical workpiece 30 located on the electric guide rail 20. The positioning blocks 21 are components that are slidably connected to the electric guide rails 20. Their function is to stably support the thin-walled cylindrical workpiece 30 during the laser cleaning process. The abutment of the positioning blocks 21 with the inner wall of the thin-walled cylindrical workpiece 30 ensures the concentricity of the workpiece and the working platform 10, and prevents collision and deformation caused by eccentricity.

[0022] During operation of the laser cleaning station, a thin-walled cylindrical workpiece 30 is placed on the work platform and connected to the motorized guide rail 20 via positioning blocks 21. A positioner adjusts the workpiece's posture to achieve the optimal position relative to the laser cleaning head. Positioning blocks 21 on the motorized guide rail 20 move synchronously, ensuring that the workpiece remains concentric with the work platform during rotation.

[0023] Furthermore, the positioner includes a position servo motor 11 fixed between the output end and the bottom of the working platform 10. The position servo motor 11 is the core component of the positioner and is responsible for driving the working platform 10 for precise rotation and positioning. The high precision and stability of the servo motor enable the working platform to achieve precise position shifting movements. A base 12 for fixing the position servo motor 11 is provided below the position servo motor 11. The base 12 is a structure for fixing the position servo motor 11, which provides a stable support for the motor. The design of the base 12 needs to ensure the stability and reliability of the motor during operation, and also needs to have sufficient rigidity to withstand the force and torque generated when the motor is running.

[0024] The position servo motor 11 is fixedly connected to the bottom of the work platform 10 through its output terminal. The motor receives commands from the control system and precisely controls the rotation angle and speed of the work platform. The base 12 provides a solid foundation for the position servo motor, ensuring the stability and accuracy of the motor when driving the work platform. When the laser cleaning head needs to clean different parts of the workpiece, the position servo motor 11 adjusts the work platform's posture according to a preset program or real-time feedback, ensuring that the part to be cleaned is accurately aligned with the laser head.

[0025] Furthermore, it also includes a plurality of support columns 50 located at the bottom of the working platform 10. The support columns 50 are a plurality of columnar structures arranged at the bottom of the working platform. Their main function is to support the working platform 10 and ensure its stability. The design of the support columns 50 needs to take into account the load-bearing capacity, stability and the connection method with the working platform 10 to ensure that the working platform will not be displaced or deformed due to the weight of the workpiece or the vibration during the cleaning process during the laser cleaning process. And the ball 51 is movably arranged at the top of the support column 50 and is connected to the bottom of the working platform 10 in a rolling manner. The ball is a small sphere movably arranged at the top of the support column, and they are connected to the bottom of the working platform in a rolling manner. The function of the ball is to reduce the friction of the working platform during the displacement process and provide smooth rotational motion.

[0026] When the position-shifting servo motor 11 drives the work platform 10 to rotate or tilt, the balls 51 roll on the tops of the support columns 50, reducing friction and wear during the movement of the work platform 10. This rolling motion of the balls 51 allows the work platform 10 to smoothly adjust its position and angle, allowing the laser head to clean the workpiece from different angles.

[0027] Furthermore, the bottom of the work platform 10 is provided with an annular groove 13, along which the top of the ball 51 fits and rolls. The annular groove 13 is a circular recess on the bottom of the work platform 10, and its primary function is to provide a rolling path for the ball 51. This design allows the ball 51 to roll freely within the annular groove 13, thereby reducing friction between the work platform 10 and the support column 50 during displacement, ensuring smooth rotation of the work platform.

[0028] Furthermore, multiple support columns 50 are evenly spaced around the bottom of the work platform 10. The design of evenly spaced support columns 50 around the bottom of the work platform 10 ensures uniform and balanced force on the work platform 10. This layout ensures that the supporting force in all directions is evenly distributed when the work platform 10 rotates or tilts, preventing tilting or deformation of the platform due to uneven force.

[0029] When the position servo motor 11 drives the work platform to rotate or tilt, each support column evenly bears the weight of the work platform and the workpiece on it, ensuring the stability and levelness of the platform. This uniform support layout also helps to reduce vibration caused by uneven force on the support points.

[0030] Furthermore, it also includes a laser cleaning robot 40, which is arranged on one side of the work platform 10. The laser cleaning robot 40 is a key component of the laser cleaning workstation, which is responsible for performing the actual laser cleaning operation. The robot is usually equipped with a high-precision laser head, which can automatically clean the workpiece according to a preset program or real-time feedback. In addition, the position servo motor 11 uses an external axis servo motor that is matched with the robot system. This motor is designed to be seamlessly integrated with the robot's control system to achieve precise linkage control. The matching external axis servo motor usually has a high response speed and precise position control capability, and can move synchronously with the other axes of the robot.

[0031] The laser cleaning robot 40 is positioned to one side of the work platform 10. This layout allows the robot to maneuver flexibly across the work platform while maintaining easy access to the workpiece. The robot's onboard laser head can perform precise cleaning operations along a pre-set path or tailored to the specific needs of the workpiece. Through the robot's automated control, the laser head scans the workpiece surface at a constant energy and speed, achieving efficient and uniform cleaning results.

[0032] Furthermore, the laser cleaning robot 40 is equipped with a laser vision tracker 41. During the cleaning process, the laser vision tracker 41 at the front of the cleaning head measures and corrects any deviations from the product surface in real time, ensuring that the laser focus remains on the product surface and ensuring effective cleaning. This solves the problem of inconsistent product dimensional deformation and automates the entire cleaning process.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
