Laser cleaning uses a high-energy laser beam to irradiate the surface of the object to be cleaned, causing the contaminants on the surface to instantly evaporate or peel off, thereby achieving the purpose of cleaning. Among them, the object to be cleaned includes, but is not limited to, an engine. Taking the engine as an example for specific expansion and introduction, when this technology is applied to the cleaning of the engine combustion chamber, it can effectively avoid the disadvantages of the traditional physical or chemical cleaning methods of the engine, effectively remove impurities such as oil scale and carbon deposits accumulated inside the combustion chamber, achieve a fast and non-destructive cleaning effect, without disassembling the engine, and will not cause secondary damage to the engine.

Detailed Embodiments

[0027] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific embodiments of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0028] In the description of the present application, it still needs to be noted that the proximal end refers to the end of the instrument or component close to the operator, and the distal end refers to the end of the instrument or component far from the operator; the axial direction refers to the direction parallel to the center line connecting the distal end and the proximal end of the instrument or component, the radial direction refers to the direction perpendicular to the axial direction, and the circumferential direction refers to the direction surrounding the axial direction.

[0029] Referring to Figures 1 to 3 , Figure 1 FIG. shows a perspective structure diagram of a laser cleaning device according to an embodiment of the present application. Figure 2 FIG. shows Figure 1 an exploded structure diagram of the structure shown. Figure 3 FIG. shows Figure 1 a proximal structure diagram of the light passing axis 40 in the structure shown. A laser cleaning device provided by an embodiment of the present application includes: a housing 10, a laser emitting assembly 20, a driving assembly 30, and a light passing axis 40. The laser emitting assembly 20 is installed inside the housing 10. The driving assembly 30 is installed inside the housing 10. The light passing axes 40 are provided in multiple numbers and are of different specifications and models. The proximal end of each light passing axis 40 penetrates the housing 10 and extends into the housing 10 and is detachably connected to the driving assembly 30. A reflecting mirror 50 and a window 41 are provided at the distal end of each light passing axis 40. The driving assembly 30 is used to drive the light passing axis 40 to rotate to adjust the angular position of the reflecting mirror 50 and the window 41. The laser of the laser emitting assembly 20 is reflected by the reflecting mirror 50 and then emitted outward from the window 41.

[0030] It should be noted that for light passing axes 40 of different specifications and models, the length dimensions of the light passing axes 40 are different, or the shapes, positions, and contour dimensions of the windows 41 opened on the light passing axes 40 are different. Specifically, how to set them can be correspondingly determined with reference to the objects to be cleaned of the corresponding specifications and models.

[0031] For the above-mentioned laser cleaning device, since the light passing axes 40 are provided in multiple numbers and are of different specifications and models, and the light passing axes 40 are detachably arranged, for the cleaning work of objects to be cleaned of different models and for the cleaning work of different areas of objects to be cleaned of the same specification and model, it is possible to select and install the light passing axes 40 of the corresponding models to ensure the cleaning effect on the objects to be cleaned. Thus, there is no need to configure laser cleaning devices of different specifications and models, greatly reducing the cost.

[0032] In addition, during the actual cleaning operation, the laser emitted by the laser emission component 20 is incident on the reflecting mirror 50. After receiving the ultra-long collimated light and the light spot, the reflecting mirror 50 plays a reflecting role, causing the laser to emit outward from the window 41. When it is emitted onto the surface of the object to be cleaned, it plays a cleaning role; and under the drive of the drive component 30, the reflecting mirror 50 and the window 41 can be adjusted to various angular positions, so as to realize the all-round cleaning of the carbon deposits on the surface of the object to be cleaned, with high cleaning efficiency, and also ensure the uniformity and thoroughness of the cleaning.

[0033] In some embodiments, the connection mode between the proximal end of the optical axis 40 and the drive component 30 includes but is not limited to threaded fit connection, snap connection, interference fit connection, connection using fixing pins or rivets, etc. Specifically, in this embodiment, the connection between the proximal end of the optical axis 40 and the drive component 30 preferably uses threaded fit connection, which not only facilitates disassembly and assembly, but also has a high coaxiality between the optical axis 40 and the laser light of the laser emission component 20 after the optical axis 40 and the drive component 30 are assembled together, so as to improve the accuracy and stability of laser transmission, and thus has a better cleaning effect.

[0034] Please refer to Figure 2 and Figure 3 , in a specific embodiment, the proximal end of the optical axis 40 is provided with a first thread 42, and the drive component 30 is provided with a second thread adapted to the first thread 42. Thus, the proximal end of the optical axis 40 is detachably connected to the drive component 30 through the mutual cooperation of the first thread 42 and the second thread. Among them, in order to improve the operation efficiency, the design of quickly replacing the optical axis 40 is particularly important. Specifically, both the first thread 42 and the second thread are rectangular threads. Compared with other types of threads, the rectangular thread has a larger thickness d of the thread tooth and a larger pitch L. In this case, when the depth of the threaded hole of the drive component 30 is certain, the proximal end of the optical axis 40 and the drive component 30 can be assembled or disassembled by rotating a relatively small number of turns, playing a quick-twist role, so that the optical axis 40 can be quickly rotated and replaced, greatly improving the operation efficiency.

[0035] In some embodiments, the pitch L of the first thread 42 includes, but is not limited to, 5 mm to 25 mm, specifically, for example, 5 mm, 7 mm, 10 mm, 13 mm, 15 mm, 20 mm, or 25 mm, etc. Of course, the pitch L of the first thread 42 can also be set to any size less than 5 mm and greater than 25 mm. In addition, the number of threads at the proximal end of the optical axis 40 includes, but is not limited to, 5 to 25, specifically, for example, 5, 8, 10, 12, 15, 20, or 25, etc. Of course, the number of threads of the first thread 42 can also be set to any value less than 5 and greater than 25. With such a setting, on the one hand, it can make the proximal end of the optical axis 40 connected and fixed to the driving assembly 30, ensure the docking stability and coaxiality, so as to improve the accuracy and stability of laser transmission; on the other hand, it can also enable the quick disassembly and assembly of the optical axis 40 and the driving assembly 30, and the appropriate specification and model of the optical axis 40 can be selected for installation according to actual needs, with relatively high working efficiency.

[0036] In some embodiments, the mirror 50 includes, but is not limited to, a reflection structure obtained by chamfering a cylinder, for example. The chamfered surface of the mirror 50 is arranged at an angle with the axis of the cylinder, and the chamfered surface is also the reflection surface for reflecting laser light. Among them, the cylinder is, for example, adapted to the shape of the light passing hole of the optical axis 40 and can be stably installed inside the optical axis 40. In addition, the mirror 50 is fixedly installed on the optical axis 40 by various fasteners including, but not limited to, bonding, clamping, using pins, rivets, screws, etc., and can be flexibly adjusted and set according to actual needs, which will not be limited here.

[0037] Optionally, the shape of the window 41 includes, but is not limited to, various regular and irregular shapes such as square, U-shaped, circular, oval, etc., as long as it can avoid the laser light reflected by the mirror 50, and can be flexibly adjusted and set according to actual needs.

[0038] Please refer to Figure 2 、 Figure 4 and Figure 5 In some embodiments, the optical axis 40 includes a first optical axis 43 and a second optical axis 44 that are coaxially connected in sequence along the laser transmission direction. The first thread 42 is formed on the proximal end of the first optical axis 43. The window 41 is formed on the distal end of the second optical axis 44, and the inner diameter of the first optical axis 43 is greater than the inner diameter of the second optical axis 44. In this way, the diameter size of the second optical axis 44 can be designed to be relatively small, so as to facilitate extending into a narrow space, such as a gap, for related cleaning or cutting treatment of the internal structure of the product; the diameter size of the first optical axis 43 can be designed to be relatively large, so that the stiffness is large enough and it is not easy to be damaged or deformed.

[0039] Based on the foregoing embodiments, the laser cleaning device further includes a protective sleeve 60 sleeved outside the optical transmission shaft 40. Specifically, the protective sleeve 60 is connected to the housing 10, and the optical transmission shaft 40 can be inserted into the inside of the protective sleeve 60 and withdrawn from the inside of the protective sleeve 60 during disassembly and assembly. Specifically, the protective sleeve 60 is sleeved outside the first optical transmission shaft 43. The design of the protective sleeve 60 is intended to provide a firm support for the optical transmission shaft 40 during operation, including but not limited to being made of high-strength materials, which can effectively resist external impacts and abrasions, thereby extending the service life of the optical transmission shaft 40.

[0040] In one embodiment, the driving assembly 30 includes a driving motor 31, a driving gear, a driven gear 32, and a bracket 33. The bracket 33 is connected to the inner wall of the housing 10. The driving motor 31 is installed on the bracket 33. The rotating shaft of the driving motor 31 is connected to the driving gear, the driving gear meshes with the driven gear 32, the driven gear 32 is rotatably connected to the bracket 33, the driven gear 32 is coaxially and detachably connected to the optical transmission shaft 40, and the driven gear 32 is further provided with an axial through hole 321 communicating with the optical transmission shaft 40. Thus, when the driving motor 31 rotates, it drives the driving gear to rotate, the driving gear drives the driven gear 32 to rotate, and the driven gear 32 correspondingly drives the optical transmission shaft 40 to rotate. In addition, the driven gear 32 is driven to rotate by the meshing of the driving gear and the driven gear 32. The driven gear 32 is arranged along the central axis of the housing 10, and the driving gear and the driving motor 31 are arranged on one side of the central axis of the housing 10, so as to avoid the laser light incident into the axial through hole 321.

[0041] In some embodiments, the outer diameter of the driving gear is less than and greater than the outer diameter of the driven gear 32. When the driving gear drives the driven gear 32 to rotate, it plays a role in deceleration and has high stability. In addition, the second thread is specifically formed on the inner wall of the axial through hole 321 and combines with the first thread 42 at the proximal end of the optical transmission shaft 40, so that the optical transmission shaft 40 can be quickly rotated and replaced, greatly improving the operation efficiency.

[0042] In some embodiments, the bracket 33 includes two mounting plates 331 arranged at intervals relative to each other, and at least two support columns 332 respectively connected to the two mounting plates 331. Optionally, the support columns 332 include but are not limited to two, three, four or other numbers. In this embodiment, the support columns 332 are, for example, three, which can improve the connection stability of the two mounting plates 331 and prevent the gears from loosening due to vibration or long-term operation. In addition, each mounting plate 331 is connected to the inner wall of the housing 10, and a movable hole is provided in the middle of each mounting plate 331. The two axial end portions of the driven gear 32 are respectively rotatably inserted through the two movable holes.

[0043] To ensure visual monitoring during the operation process, optionally, the laser cleaning device further includes a camera 71 disposed inside the housing 10. The camera 71 is located outside the optical axis 40 and faces the light passing hole of the optical axis 40 to receive the image reflected by the reflector 50. In this way, during the process of using the laser to clean the object to be cleaned, the image of the object to be cleaned can also be synchronously reflected to the camera 71 by the reflector 50 and received by the camera 71, so that it is convenient to observe the treatment situation of the product surface, the situation at the operation site can be captured in real time, providing intuitive operation monitoring for the operator and ensuring the safety and accuracy of the operation. In addition, the camera 71 can avoid the laser light of the laser emitting assembly 20. In this way, since the camera 71 can avoid the laser light of the laser emitting assembly 20, that is, the camera 71 will not be damaged by contacting the laser light, the service life is extended. Moreover, the camera 71 is located outside the optical axis 40 instead of inside the optical axis 40, avoiding the reduction of heat dissipation performance and rapid temperature rise inside the optical axis 40, which may cause usage failures. In addition, the disassembly and assembly efficiency of the camera 71 can also be improved.

[0044] In one embodiment, the laser cleaning device further includes a support base 72 mounted on the bracket 33. The camera 71 is mounted on the support base 72. Specifically, the support base 72 is installed on one of the mounting plates 331 away from the reflector 50. When the camera 71 is mounted on the support base 72, the camera 71 can be located at the proximal end of the optical axis 40 and face the light passing hole of the optical axis 40. In addition, under the support of the support base 72, the assembly efficiency and stability of the camera 71 can be improved.

[0045] Please refer to Figure 1 And Figure 2 , in some embodiments, the laser cleaning device further includes a communication connector 73 electrically connected to the camera 71. The communication connector 73 includes, but is not limited to, a USB interface or other types of interfaces, and the communication connector 73 can output the image information obtained by the camera 71 outward. In addition, a first opening 101 adapted to the communication connector 73 is formed on the side wall of the housing 10, and the communication connector 73 is disposed in the first opening 101.

[0046] In one embodiment, the laser cleaning device further includes an air inlet joint 80. The air inlet joint 80 is installed at a position on the housing 10 adjacent to the proximal end of the light transmission axis 40. The air inlet joint 80 is used to communicate with the cold air blowing device. In this way, after the air inlet joint 80 is connected to the air outlet end of the cold air blowing device, the cold air blowing device blows cold air into the interior of the housing 10, and the cold air correspondingly flows from the proximal end of the light transmission axis 40 into the interior of the light transmission axis 40, realizing effective heat dissipation for the laser light column, having a high heat dissipation efficiency, and playing a role in cooling down. In addition, since the camera 71 is also located at the proximal end of the light transmission axis 40, the cold air entering the interior of the housing 10 will synchronously contact the camera 71, thereby playing a good heat dissipation role for the camera 71, and further improving the service performance and service life of the camera 71.

[0047] In some embodiments, the air inlet joint 80 includes, but is not limited to, a quick connector, which facilitates quick connection to the air outlet end of the cold air blowing device.

[0048] Please refer to Figure 2 And Figure 6 As shown in, in one embodiment, the laser emitting assembly 20 includes a laser output head 21 and a galvanometer assembly 22 disposed inside the housing 10. The laser light of the laser output head 21 is incident on the galvanometer assembly 22, and the galvanometer assembly 22 is used to output the laser light to the reflector 50. In this way, under the action of the galvanometer assembly 22, the laser light of the laser output head 21 can be formed into a predetermined pattern and light spot, and the predetermined pattern and light spot are reflected by the reflector plate onto the surface of the object to be cleaned, thereby obtaining a good cleaning effect.

[0049] Please refer to Figure 2 And Figure 6 As shown in, in one embodiment, the galvanometer assembly 22 includes a first galvanometer 221, a second galvanometer 222, a first motor 223, and a second motor 224. The first motor 223 is connected to the first galvanometer 221, and the first motor 223 is used to drive the first galvanometer 221 to rotate around the first axis. The second motor 224 is connected to the second galvanometer 222, and the second motor 224 is used to drive the second galvanometer 222 to rotate around the second axis. The laser emission direction of the laser output head 21 is parallel to the first axis, and the second axis is coaxially arranged with the axis of the light transmission axis 40. In this way, the laser output by the laser head forms a predetermined pattern and light spot through the mutual refraction of the first galvanometer 221 and the second galvanometer 222. Specifically, when the rotation angles and rotation speeds of the first galvanometer 221 and the second galvanometer 222 are respectively adjusted, the shape of the laser pattern can be correspondingly adjusted. This process is completed, for example, under the control of a controller, to precisely control the angles and rotation speeds of the galvanometers to ensure that the laser can accurately irradiate the target area of the object to be cleaned.

[0050] Among them, the first motor 223 and the second motor 224 can each be either directly connected to the inner wall of the housing 10 or indirectly mounted on the inner wall of the housing 10, and can be specifically adjusted and set flexibly according to actual needs, and are not limited herein.

[0051] In one embodiment, the laser cleaning device further includes a focusing lens 23, a convex lens 24, and a protective lens 25 that are disposed inside the housing 10 and are sequentially arranged between the galvanometer assembly 22 and the proximal end of the optical axis 40. In this way, the laser light formed by the galvanometer assembly 22 will sequentially undergo focusing processing through the focusing lens 23, diffusion processing through the convex lens 24, and protection processing through the protective lens 25, so that the laser can emit ultra-long collimated light and light spots, providing sufficient energy and accuracy for subsequent cleaning operations.

[0052] Please refer to Figure 2 and Figure 6 , in some embodiments, the housing 10 includes a first housing 11, a second housing 12, a third housing 13, a fourth housing 14, and a fifth housing 15. The second housing 12 is provided with a first connection portion and a second connection portion. The first housing 11 is connected to the first connection portion. The laser output head 21 and the first motor 223 are disposed inside the first housing 11. The first motor 223 is disposed inside the first housing 11, and the first galvanometer 221 is rotatably disposed inside the second housing 12; the second motor 224 is disposed inside the second housing 12, and the second galvanometer 222 is rotatably disposed inside the second housing 12. The second connection portion, the third housing 13, the fourth housing 14, and the fifth housing 15 are sequentially connected along the second axis. The focusing lens 23, the convex lens 24, and the protective lens 25 are specifically arranged inside the third housing 13, for example. The bracket 33 is specifically disposed inside the fourth housing 14. The protective sleeve 60 is specifically mounted on the fifth housing 15 and extends outwards from the fifth housing 15. In addition, the laser cleaning device further includes a locking nut 16, a protective cover 17, and a flange 18. The first housing 11 and the first connection portion are specifically connected by the locking nut 16, for example, and a flange 18 is installed at the other end of the first housing 11. In addition, a protective cover 17 is provided at a position on the second housing 12 opposite to the second connection portion, and the protective cover 17 protects the second motor 224, the first galvanometer 221, and the second galvanometer 222.
