Description

Technical Field

[0001] This application relates to the field of laser equipment manufacturing, specifically a dual-axis rotary laser cleaning machine. Background Technology

[0002] Laser cleaning is a non-contact, safe, and environmentally friendly cleaning method. It uses a laser beam to break down contaminants, causing them to detach from the object being cleaned. It features non-contact operation, no heat effect, and applicability to various materials.

[0003] Existing laser cleaning machines generally include a machine base and a drive module mounted on the machine base. The drive module is equipped with a laser cleaning head, which performs laser cleaning on the workpiece placed on the machine base. During the cleaning process, the drive module drives the laser cleaning head to move, so that the laser beam emitted by the laser cleaning head falls on the workpiece and scans the surface of the workpiece to be cleaned, thereby performing laser cleaning on the workpiece.

[0004] In the production process, it is often necessary to clean irregularly shaped workpieces (such as turbine blades, molds, welds, etc.) with curved, angular, or uneven surfaces. Existing laser cleaning machines often have difficulty covering the surface of these irregularly shaped workpieces with the laser beam emitted from the laser cleaning head. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a dual-axis rotary laser cleaning machine, the detailed technical solution of which is as follows:

[0006] A dual-axis rotary laser cleaning machine includes a cabinet, a support frame, a first translation drive mechanism, a second translation drive mechanism, a lifting drive mechanism, a cantilever, a dual-axis rotary drive mechanism, a fiber laser, and a laser cleaning head, wherein:

[0007] The cabinet has a support platform, and the support bracket is set on the support platform. The support platform is used to support the workpiece to be cleaned.

[0008] The fixed component of the first translation drive mechanism is mounted on the bracket, the fixed component of the second translation drive mechanism is connected to the movable component of the first translation drive mechanism, and the fixed component of the lifting drive mechanism is connected to the movable component of the second translation drive mechanism.

[0009] The first end of the cantilever is connected to the moving part of the lifting drive mechanism, the dual-axis rotary drive mechanism is set at the second end of the cantilever, the laser cleaning head is connected to the moving part of the dual-axis rotary drive mechanism, the fiber laser is set in the cabinet, and the fiber laser is connected to the laser cleaning head via optical fiber.

[0010] The first translation drive mechanism is used to drive the laser cleaning head to translate along the first horizontal axis, the second translation drive mechanism is used to drive the laser cleaning head to translate along the second horizontal axis, the lifting drive mechanism is used to drive the laser cleaning head to lift, and the dual-axis rotation drive mechanism is used to drive the laser cleaning head to rotate around the first horizontal axis and around the second horizontal axis, wherein the first horizontal axis is perpendicular to the second horizontal axis.

[0011] Before performing laser cleaning on the workpiece, the first translation drive mechanism and the second translation drive mechanism respectively drive the laser cleaning head to translate along the first horizontal axis and the second horizontal axis, so as to drive the laser cleaning head to the target cleaning position directly above the workpiece. Then, the lifting drive mechanism drives the laser cleaning head to rise and fall. After adjusting the height of the laser cleaning head, the laser cleaning of the workpiece can be carried out.

[0012] During the cleaning process, the dual-axis rotary drive mechanism can drive the laser cleaning head to rotate around the first horizontal axis and the second horizontal axis, thereby enabling flexible adjustment of the pitch and yaw angles of the laser cleaning head during the cleaning process. This ensures that the laser cleaning head can thoroughly clean the area of ​​the irregularly shaped workpiece to be cleaned.

[0013] In some embodiments, the dual-axis rotary drive mechanism comprises a first rotary drive unit, a rotary support, a second rotary drive unit, and a connecting plate, wherein: the rotary support is rotatably connected to the second end of the cantilever and is drively connected to the first rotary drive unit disposed on the cantilever, the first rotary drive unit being used to drive the rotary support to rotate around a first horizontal axis; the connecting plate is rotatably connected to the rotary support and is drively connected to the second rotary drive unit disposed on the rotary support, the second rotary drive unit being used to drive the connecting plate to rotate around a second horizontal axis; and the laser cleaning head is connected to the connecting plate.

[0014] A simple dual-axis rotary drive mechanism is provided, wherein a first rotary drive unit drives a rotary support to rotate around a first horizontal axis, thereby adjusting the yaw angle of the laser cleaning head. A second rotary drive unit drives a connecting plate to rotate around a second horizontal axis, thereby adjusting the pitch angle of the laser cleaning head.

[0015] In some embodiments, the rotating bracket is connected to the second end of the cantilever via a first rotating shaft, the first rotating shaft being arranged along a first horizontal axis; the first rotating drive unit includes a first motor, a first spur gear, and a first gear ring, wherein the first spur gear is fixedly mounted on the drive shaft of the first motor, the first gear ring is sleeved on the first rotating shaft, and the first gear ring meshes with the first spur gear; or, the first rotating drive unit includes a first motor, a first driving pulley, a first driven pulley, and a first synchronous belt, the first driving pulley being fixedly mounted on the drive shaft of the first motor, the first driven pulley being fixedly mounted on the first rotating shaft, and the first synchronous belt being sleeved on the first driving pulley and the first driven pulley.

[0016] Two simple and stable first rotary drive units are provided, both of which can provide stable rotary drive for the rotary support.

[0017] In some embodiments, the connecting plate is connected to the rotating bracket via a second rotating shaft, the second rotating shaft being arranged along a second horizontal axis; the second rotating drive unit includes a second motor, a second spur gear, and a second gear ring, wherein the second spur gear is fixedly mounted on the drive shaft of the second motor, the second gear ring is sleeved on the second rotating shaft, and the second gear ring meshes with the second spur gear; or, the second rotating drive unit includes a second motor, a second driving pulley, a second driven pulley, and a second synchronous belt, the second driving pulley being fixedly mounted on the drive shaft of the second motor, the second driven pulley being fixedly mounted on the second rotating shaft, and the second synchronous belt being sleeved on the second driving pulley and the second driven pulley.

[0018] Two simple and stable second rotary drive units are provided, both of which can provide stable rotary drive for the connecting plate.

[0019] In some embodiments, the dual-axis rotary laser cleaning machine includes two first translation drive mechanisms, which are arranged side-by-side and spaced apart on a support along a second horizontal axis; the two ends of the fixed part of the second translation drive mechanism are respectively connected to the movable part of one of the first translation drive mechanisms, and the two first translation drive mechanisms are configured to synchronously drive the second translation drive mechanism to translate along the first horizontal axis.

[0020] By using two first translation drive mechanisms to drive the second translation drive mechanism and its lifting drive mechanism, the laser cleaning head is translated along the first horizontal axis, which improves the overall structural stability of the dual-axis rotary laser cleaning machine of this application and further enhances the cleaning effect of the laser cleaning head.

[0021] In some embodiments, the laser cleaning head includes a connecting block, an optical fiber connector, a galvanometer, and a field lens. The connecting block is connected to a movable part of the dual-axis rotary drive mechanism, the optical fiber connector is connected to the top of the connecting block, the galvanometer is connected to the side wall of the connecting block, and the field lens is connected to the bottom of the galvanometer. An optical path connecting the optical fiber connector and the galvanometer is provided inside the connecting block. The optical fiber connector is connected to a fiber laser via an optical fiber. The laser emitted by the fiber laser is transmitted through the optical fiber to the optical path and then enters the galvanometer. The galvanometer is used to deflect and adjust the laser, and the field lens is used to focus the laser with the adjusted deflection onto the workpiece.

[0022] The connecting block allows for a stable connection with the moving parts of the dual-axis rotary drive mechanism, thereby reducing the impact of vibration on the optical path. By dynamically adjusting the laser beam using a galvanometer, the laser beam can scan the annular area to be cleaned, ensuring comprehensive cleaning of the area.

[0023] In some embodiments, the laser cleaning machine further includes a mounting bracket connected to the connecting block at its upper end, the mounting bracket extending downward to below the field lens; the mounting bracket is provided with at least one air blowing plate that communicates with an external compressed air source and extends horizontally, the air blowing plate being used to blow air horizontally to form an air curtain between the field lens and the support platform of the cabinet.

[0024] During laser cleaning, a large amount of dust is generated. When the dust rises, it contaminates the field lens, reducing its light transmittance. By installing an air blowing plate that is connected to an external compressed air source and extends horizontally, an air curtain is formed between the field lens and the support platform of the cabinet, thereby preventing dust from rising and contaminating the field lens.

[0025] In some implementations, the blowing plate has an air chamber inside, and several blowing holes communicating with the air chamber are arranged horizontally at intervals on the side wall of the blowing plate facing the field mirror. The blowing plate is also provided with a connector communicating with the air chamber and connected to a compressed air source through an air pipe.

[0026] By adjusting the air blowing plate, a horizontal air curtain is ensured to be formed between the field lens and the support surface of the cabinet.

[0027] In some implementations, a water-cooled channel surrounding the optical path is provided inside the connecting block, and the water-cooled channel is connected to an external water-cooling mechanism via a pipe.

[0028] The water-cooling mechanism is connected to the water-cooling flow channel via pipes, thus forming a water-cooling circulation loop. When the cooling water flows in the water-cooling flow channel, it cools the connecting block, which in turn cools the galvanometer and field lens, preventing them from being damaged by excessive temperature.

[0029] In some implementations, the support platform of the cabinet is equipped with several ball bearings arranged in an array.

[0030] The ball bearings can slide and guide irregularly shaped workpieces, allowing them to be smoothly adjusted to the predetermined cleaning position. Attached Figure Description

[0046] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] As described in the background section, during the production process, it is often necessary to clean irregularly shaped workpieces (such as turbine blades, molds, welds, etc.) with curved, angular, or uneven surfaces. Existing laser cleaning machines often have laser beams emitted from their cleaning heads that are difficult to cover the surfaces of irregularly shaped workpieces to be cleaned during the cleaning process.

[0048] Therefore, this application provides a dual-axis rotary cleaning machine. For example... Figures 1 to 3 As shown, the dual-axis rotary laser cleaning machine of this application includes a cabinet 1, a support 2, a first translation drive mechanism 3, a second translation drive mechanism 4, a lifting drive mechanism 5, a cantilever 6, a dual-axis rotary drive mechanism 7, a fiber laser, and a laser cleaning head 8, wherein:

[0049] The cabinet 1 has a support platform, and the bracket 2 is set on the support platform. The support platform is used to support the workpiece to be cleaned.

[0050] The fixed part of the first translation drive mechanism 3 is mounted on the bracket 2, the fixed part of the second translation drive mechanism 4 is connected to the movable part of the first translation drive mechanism 3, and the fixed part of the lifting drive mechanism 5 is connected to the movable part of the second translation drive mechanism 4.

[0051] The first end of the cantilever 6 is connected to the movable part of the lifting drive mechanism 5, the dual-axis rotary drive mechanism 7 is located at the second end of the cantilever 6, the laser cleaning head 8 is connected to the movable part of the dual-axis rotary drive mechanism 7, and the fiber laser is located inside the cabinet 1. The fiber laser is connected to the laser cleaning head 8 via an optical fiber.

[0052] The first translation drive mechanism 3 is used to drive the laser cleaning head 8 to translate along the first horizontal axis (e.g., the Y-axis), the second translation drive mechanism 4 is used to drive the laser cleaning head 8 to translate along the second horizontal axis (e.g., the X-axis), the lifting drive mechanism 5 is used to drive the laser cleaning head 8 to lift, and the dual-axis rotation drive mechanism 7 is used to drive the laser cleaning head 8 to rotate around the first horizontal axis and around the second horizontal axis, wherein the first horizontal axis is perpendicular to the second horizontal axis.

[0053] Before performing laser cleaning on the workpiece, the first translation drive mechanism 3 and the second translation drive mechanism 4 respectively drive the laser cleaning head 8 to translate along the first horizontal axis and the second horizontal axis, so as to drive the laser cleaning head 8 to the target cleaning position directly above the workpiece. Subsequently, the lifting drive mechanism 5 drives the laser cleaning head 8 to rise and fall. After adjusting the height of the laser cleaning head 8, the laser cleaning of the workpiece can be carried out.

[0054] During the cleaning process, the dual-axis rotary drive mechanism 7 can drive the laser cleaning head 8 to rotate around the first horizontal axis and around the second horizontal axis, thereby realizing flexible adjustment of the pitch angle and yaw angle of the laser cleaning head 8 during the cleaning process, ensuring that the laser cleaning head 8 can perform comprehensive cleaning on the area to be cleaned of the irregularly shaped workpiece.

[0055] The first translation drive mechanism 3, the second translation drive mechanism 4, and the lifting drive mechanism 5 can all adopt various existing linear drive modules, such as a linear drive module consisting of a motor, a lead screw, and a lead screw nut. The motor constitutes the fixed component of the linear drive module, while the lead screw nut constitutes the moving component of the linear drive module. When the motor drives the lead screw to rotate, it causes the lead screw nut to slide along the lead screw.

[0056] like Figure 2 As shown, optionally, the dual-axis rotary drive mechanism 7 includes a first rotary drive unit 71, a rotary support 72, a second rotary drive unit 73, and a connecting plate 74. The rotary support 72 is rotatably connected to the second end of the cantilever 6 and is driveably connected to the first rotary drive unit 71 mounted on the cantilever 6. The first rotary drive unit 71 drives the rotary support 72 to rotate around a first horizontal axis. The connecting plate 74 is rotatably connected to the rotary support 72 and is drively connected to the second rotary drive unit 73 mounted on the rotary support 72. The second rotary drive unit 73 drives the connecting plate 74 to rotate around a second horizontal axis. The laser cleaning head 8 is connected to the connecting plate 74.

[0057] As can be seen, the first rotary drive unit 71 drives the rotary support 72 to rotate around the first horizontal axis (such as the Y-axis), thereby flexibly adjusting the yaw angle of the laser cleaning head 8. The second rotary drive unit 73 drives the connecting plate 74 to rotate around the second horizontal axis (such as the X-axis), thereby flexibly adjusting the pitch angle of the laser cleaning head 8.

[0058] Optionally, the rotating bracket 72 is connected to the second end of the cantilever 6 via a first rotating shaft, which is positioned along a first horizontal axis. Alternatively, the first rotating shaft can be inserted into the inner ring of a roller bearing.

[0059] In one alternative embodiment, the first rotary drive unit 71 includes a first motor, a first spur gear, and a first gear ring. The first spur gear is fixedly mounted on the drive shaft of the first motor, and the first gear ring is sleeved on the first rotating shaft, meshing with the first spur gear. When the first motor drives the first spur gear to rotate, the first spur gear drives the first rotating shaft to rotate via the first gear ring, thereby causing the rotary support 72 to rotate around the first horizontal axis.

[0060] In another alternative embodiment, the first rotary drive unit 71 includes a first motor, a first driving pulley, a first driven pulley, and a first synchronous belt. The first driving pulley is fixedly mounted on the drive shaft of the first motor, and the first driven pulley is fixedly mounted on the first rotating shaft. The first synchronous belt is sleeved on the first driving pulley and the first driven pulley. When the first motor drives the first driving pulley to rotate, the first driving pulley drives the first driven pulley and the first rotating shaft to rotate synchronously via the first synchronous belt, thereby driving the rotating bracket 72 to rotate around the first horizontal axis.

[0061] Both of the aforementioned first rotary drive units 71 are capable of providing stable rotary drive for the rotary support 72. Of course, in other embodiments, the first rotary drive unit 71 may also employ other existing rotary drive mechanisms, as long as they are capable of driving the rotary support 72 to rotate around the first horizontal axis.

[0062] Optionally, the connecting plate 74 is connected to the rotating bracket 72 via a second rotating shaft, which is arranged along a second horizontal axis.

[0063] In one alternative embodiment, the second rotary drive unit 73 includes a second motor, a second spur gear, and a second gear ring. The second spur gear is fixedly mounted on the drive shaft of the second motor, and the second gear ring is sleeved on the second rotating shaft, meshing with the second spur gear. When the second motor drives the second spur gear to rotate, the second spur gear drives the second rotating shaft to rotate via the second gear ring, thereby causing the connecting plate 74 to rotate around the second horizontal axis.

[0064] In another alternative embodiment, the second rotary drive unit 73 includes a second motor, a second driving pulley, a second driven pulley, and a second synchronous belt. The second driving pulley is fixedly mounted on the drive shaft of the second motor, and the second driven pulley is fixedly mounted on the second rotating shaft. The second synchronous belt is sleeved on the second driving pulley and the second driven pulley. When the second motor drives the second driving pulley to rotate, the second driving pulley drives the second driven pulley and the second rotating shaft to rotate synchronously via the second synchronous belt, thereby driving the connecting plate 74 to rotate around the second horizontal axis.

[0065] Both types of second rotary drive units 73 described above can provide stable rotary drive for the connecting plate 74. Of course, in other embodiments, the second rotary drive unit 73 can also adopt other existing rotary drive mechanisms, as long as they can drive the second rotary drive unit 73 to rotate around the second horizontal axis.

[0066] like Figure 1 As shown, optionally, the dual-axis rotary laser cleaning machine in this embodiment includes two first translation drive mechanisms 3, which are arranged side by side and spaced apart on the bracket 2 along the second horizontal axis.

[0067] The two ends of the fixed part of the second translation drive mechanism 4 are respectively connected to the movable part of one of the first translation drive mechanisms 3. The two first translation drive mechanisms 3 are configured to synchronously drive the second translation drive mechanism 4 to translate along the first horizontal axis.

[0068] By cooperating with two first translation drive mechanisms 3 to drive the second translation drive mechanism 4 and its lifting drive mechanism 5, the laser cleaning head 8 translates along the first horizontal axis, thereby improving the overall structural stability of the dual-axis rotary laser cleaning machine of this application and further enhancing the cleaning effect of the laser cleaning head 8.

[0069] like Figure 3 As shown, optionally, the laser cleaning head 8 includes a connecting block 81, an optical fiber connector 82, a galvanometer 83, and a field lens 84. The connecting block 81 is connected to the movable part of the dual-axis rotary drive mechanism 7, the optical fiber connector 82 is connected to the top of the connecting block 81, the galvanometer 83 is connected to the side wall of the connecting block 81, and the field lens 84 is connected to the bottom of the galvanometer 83. An optical path connecting the optical fiber connector 82 and the galvanometer 83 is provided inside the connecting block 81.

[0070] The fiber optic connector 82 is connected to the fiber laser via an optical fiber. The laser emitted by the fiber laser is transmitted through the optical fiber to the optical path and then enters the galvanometer 83. The galvanometer 83 is used to deflect and adjust the laser. The field lens 84 is used to focus the laser that has been deflected and adjusted onto the workpiece.

[0071] The connecting block 81 provides a stable connection to the moving parts of the dual-axis rotary drive mechanism 7, thereby reducing the impact of vibration on the optical path. The laser beam is dynamically adjusted by the galvanometer 83, enabling it to scan the annular area to be cleaned, ensuring comprehensive cleaning of the area.

[0072] Of course, in order to ensure that the laser can accurately enter the galvanometer 83 through the optical path, optical path components such as reflectors and convex mirrors can be set in the optical path.

[0073] During laser cleaning, a large amount of dust is generated. As the dust rises, it contaminates field lens 84, reducing its light transmittance. To solve this problem, such as... Figure 3 As shown, optionally, the dual-axis rotary laser cleaning machine in this embodiment further includes a mounting bracket 9 connected to the connecting block 81 at its upper end, and the mounting bracket 9 extends downward to below the field lens 84. The mounting bracket 9 is provided with at least one air blowing plate 10 that communicates with an external compressed air source and extends horizontally. The air blowing plate 10 is used to blow air in the horizontal direction to form an air curtain between the field lens 84 and the support platform of the cabinet 1.

[0074] Air curtains can prevent dust from rising and contaminating the field lens during the laser cleaning process.

[0075] Optionally, the blowing plate 10 is provided with an air cavity, and a number of blowing holes communicating with the air cavity are arranged at intervals along the horizontal direction on the side wall of the blowing plate 10 facing the field mirror 84. The blowing plate 10 is also provided with a connector communicating with the air cavity and communicating with a compressed air source through an air pipe.

[0076] By setting the air blowing plate 10, a horizontal air curtain is ensured to be formed between the field mirror 84 and the support platform of the cabinet 1.

[0077] Optionally, the connecting block 81 is provided with a water-cooled flow channel surrounding the optical path. The water-cooled flow channel is connected to an external water-cooling mechanism via a pipe, thereby forming a water-cooled circulation loop. When the cooling water flows in the water-cooled flow channel, it cools the connecting block 81, which in turn cools the galvanometer 83 and the field lens 84, preventing the galvanometer 83 and the field lens 84 from being damaged due to excessive temperature.

[0078] like Figure 1 As shown, optionally, the support platform of the cabinet 1 is provided with a plurality of ball bearings 110 arranged in an array. The ball bearings 110 can slide and guide and position the irregularly shaped workpiece, so that the irregularly shaped workpiece can be smoothly adjusted to the predetermined cleaning position.
