[0032] The present invention will be described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] The technical solutions of the present disclosure will be described below by taking a laser cleaning device applicable to complex components disclosed in the present application as an example.

[0036] According to an example of the present disclosure, from Figures 1 - 10 the perspective of the three-dimensional view of the laser cleaning device applicable to complex components shown, the laser cleaning device may include a laser cleaning mechanism 100, a product loading mechanism 200, and an adjusting mechanism 300 that form the whole or at least a part of its appearance.

[0037] The composition and connection relationship of the laser cleaning mechanism 100, the product loading mechanism 200, and the adjustment mechanism 300 will be described in detail below with specific examples.

[0038] Please refer to Figures 1 - 3 , the product loading mechanism 200 includes a product conveying seat 201, a product placement table 202, and a driving component 203. The driving component 203 is connected to the product placement table 202 and is used to drive the product placement table 202 to move on the product conveying seat 201.

[0039] A control cabinet 204 is arranged on the product placement table 202 to house the electric control components and the driving component 203, avoiding damage caused by dust, debris, and laser beams. In some embodiments, the driving component 203 is a driving motor. A moving guide rail 205 and a toothed plate 206 are arranged in the product conveying seat 201 along the moving direction of the product placement table 202. A gear 207 is provided on the output shaft of the driving motor, and the gear 207 meshes with the toothed plate 206 to drive the product placement table 202 to move and convey the product to the cleaning area.

[0040] When using the laser cleaning mechanism 100 to clean the surface of inorganic substances, a large amount of debris and dust will be generated. If the moving guide rail 205 is not protected, the debris and dust falling into the moving guide rail 205 can easily cause the product placement table 202 to get stuck when moving. Therefore, two sets of bellows protective covers 209 are arranged on both sides of the product placement table 202. One end of each of the two sets of bellows protective covers 209 is fixedly connected to the product conveying seat 201 respectively, and the other end is fixedly connected to the product placement table 202 respectively. When the product placement table 202 moves, it will drag one end of the bellows protective cover 209 to unfold and the other end of the bellows protective cover 209 to contract, thereby blocking the debris and dust outside and being free from the influence of debris and dust. In addition, a cable chain 208 is arranged in the product conveying seat 201. One end of the cable chain 208 is fixed in the product conveying seat 201, and the other end is connected to the control cabinet 204, and the power cord passes through the cable chain 208.

[0041] In the above embodiment, since the object to be cleaned is a mold with a relatively large weight, a motor with a certain power is required as the driving source to send the product into the cleaning area. At the same time, considering that the volume of the control components is also relatively large, it is realized by arranging the control cabinet 204 outside the product placement table 202, which is also conducive to the convenience of maintenance by the staff in case of a failure.

[0042] By Figures 6 - 9As can be seen from the three-dimensional diagram of the laser cleaning mechanism 100 shown, the laser cleaning mechanism 100 includes a protective cover 101 for allowing the laser beam to be emitted, and a field lens (not shown) is arranged in the protective cover 101. Combined with the protective cover 101 structure in which the laser emission port is roughly flat, the beam energy can be concentrated to improve the cleaning quality; further, a mounting port 1010 is provided on the protective cover 101 for setting a detachable lens mounting seat 102, and the field lens is fixed on the lens mounting seat 102. The field lens can be cleaned or replaced by removing the lens mounting seat 102, thereby improving the efficiency of the operator.

[0043] In some embodiments, a threaded hole is provided on the outer wall of the protective cover 101, and a through hole is provided on the lens mounting seat 102 in the direction corresponding to the threaded hole. The lens mounting seat 102 is locked to the protective cover by penetrating the through hole and connecting it with the threaded hole with a locking screw 103. The locking state can be released by simply twisting it by hand, thereby improving the convenience of removal.

[0044] During the cleaning process, debris will be generated. In order to prevent the debris from damaging the lens, a wind knife cover 104 is set on the protective cover 101. The wind knife cover 104 is provided with a wind knife hole 1011 connected to the inner cavity of the protective cover 101. The wind knife hole 1011 is located between the field lens and the laser emission port. By filling in air flow, a wind wall is formed near the field lens to prevent debris or dust from damaging the field lens.

[0045] like Figure 7 As shown, a sensor adjustment plate 106 is provided on the distance sensor 105, and a waist-shaped hole 1012 is provided on the sensor adjustment plate 106. An adapter plate 107 fixedly connected to the waist-shaped hole 1012 is provided outside the protective cover 101. The sensor adjustment plate 106 can fine-tune the position of the distance sensor 105 through the waist-shaped hole 1012. The distance sensor 105 is used to measure the distance from the field lens to the surface of the object to be cleaned to adjust the focal length.

[0046] like Figure 6 、 Figure 7 , also includes a hollow rotating shaft 108, an isolation seat 109 and a hollow turntable 114 connected to the protective cover 101, a beam splitter group 110 is arranged in the hollow rotating shaft 108, a beam splitter group 2 111 is arranged in the isolation seat 109, a galvanometer 112 is arranged in the hollow turntable 114, the beam splitter group 2 111 is used to reflect the light beam emitted from the beam splitter group 110 to the galvanometer 112, the galvanometer 112 is used to reflect the light beam to the field mirror, and an adjustment motor 113 is provided on the hollow turntable 114, the output end of the adjustment motor 113 is connected to the galvanometer 112, and the direction of the galvanometer 112 is adjusted by the adjustment motor 113 to change the emission position of the laser beam.

[0047] Please refer to Figures 4 - 6, the adjusting mechanism 300 includes a bench 301 and a rotating frame 302. An X-axis moving member 303, a Y-axis moving member 304 for driving the rotating frame 302 to move in the X-axis and Y-axis directions, and a first rotating member 305 for driving the rotating frame 302 to rotate are provided on the bench 301. A plurality of moving frames 306 arranged along the Z-axis direction are provided on the rotating frame 302. A Z-axis moving member 307 for driving a plurality of laser cleaning mechanisms 100 to move in the Z-axis direction and a second rotating member 308 for driving the laser cleaning mechanism 100 to rotate are provided on each of the plurality of moving frames 306. The output end of the second rotating member 308 is connected to the hollow rotating shaft 108. The isolation seat 109 is rotatably arranged with the hollow turntable 114, and a third rotating member 309 for driving the hollow turntable 114 to rotate is provided on the isolation seat 109.

[0048] As Figure 10 , it can be understood that the plurality of laser cleaning mechanisms 100 move or rotate synchronously to the cleaning position under the action of the X-axis moving member 303, the Y-axis moving member 304, and the first rotating member 305. Subsequently, according to the focal length measured by the distance measuring sensor 105, the laser cleaning mechanism 100 is adaptively adjusted through the Z-axis moving member 307, the second rotating member 308, and the third rotating member 309 to solve the problem of inconsistent cleaning effects caused by different focal lengths during cleaning.

[0049] Through the understanding of the above specific embodiments, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to such specific embodiments. Based on the disclosed embodiments, those skilled in the relevant art can arbitrarily combine different technical features to achieve different technical solutions, and can also be combined with different forms of additional functions to form other technical solutions. Therefore, the protection scope of this application is only defined by the scope of the appended claims.

[0050] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention pertains, based on the idea of the present invention, several simple deductions, deformations, or substitutions can also be made.
