Description

Technical Field

[0001] The invention relates to a laser cleaning machine, in particular to a laser cleaning head device and laser cleaning equipment with a protective function. Background Art

[0002] Laser cleaning is an industrial cleaning method. Laser ablation (the scientific name for laser cleaning) or photoablation is the process of removing material from a solid (or sometimes liquid) surface by irradiating it with a laser beam. The material is heated by the absorbed laser energy and evaporates or sublimates to achieve the cleaning effect.

[0003] The equipment used for laser cleaning is called a laser cleaning machine. The laser cleaning machine includes a machine body and a cleaning head. Optical glass is usually provided at the laser emission outlet of the cleaning head. The optical glass plays a role in protecting the internal components of the cleaning head. In actual use, laser cleaning will cause the stains on the workpiece to evaporate and drift into the air, resulting in a poor working environment for the laser cleaning machine. The surface of the optical glass is prone to stains in this environment, resulting in reduced light transmittance. In order to avoid this situation, the optical glass needs to be cleaned regularly by manual labor. The cleaning method is to manually wipe the surface of the optical glass with a special fingertip. Although the above-mentioned manual wiping method using finger cots is simple, it has high requirements on manpower. Firstly, manual wiping cannot guarantee the wiping effect, which varies from person to person. Some irresponsible staff members wipe carelessly, and even scratches may appear on the surface of the optical glass during the wiping process, further causing damage to the optical glass. Secondly, the time interval of manual wiping is not easy to control, and is affected by the specific cleaning situation. Sometimes shorter wiping intervals are required, that is, the wiping frequency is higher, and sometimes longer wiping intervals are required, that is, the wiping frequency is lower. This more complicated situation causes manual wiping to be unable to fully meet the needs of optical glass maintenance. Therefore, a laser cleaning head device and laser cleaning equipment with protective function are proposed to solve the above-mentioned problems. Summary of the invention

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0020] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0021] Embodiment 1 Please refer to the figure Figure 1 , Figure 2 as well as Figure 4 , a laser cleaning device, comprising: body 1; and The laser cleaning head device is connected to the machine body 1 through a cable and comprises a cleaning head 2 and a protective device, wherein: A cleaning head 2, which is connected to the machine body 1 through a cable, and includes a cleaning head body 21, an upper surface of the cleaning head body 21 is provided with a mounting tube 22, and an upper surface of the mounting tube 22 is provided with a mounting groove 23; A protective device, comprising a mounting seat 3 and a protective member 4, wherein the mounting seat 3 comprises a base 31, a mounting plate 32 is disposed on the lower surface of the base 31, a threaded hole is disposed on the side of the mounting plate 32, the mounting plate 32 extends to the inside of the mounting groove 23, and is connected to the mounting tube 22 by screws; Based on the above, the setting of the mounting cylinder 22 and the mounting groove 23 enables the mounting seat 3 to be fixed with screws after the mounting plate 32 is inserted into the interior of the mounting groove 23, thereby connecting the protective device and the cleaning head 2 to each other. At this time, the protective part 4 plays a protective role on the cleaning head 2.

[0022] Embodiment 2 Based on the first embodiment, Figure 3 , Figure 7 and Figure 8 As shown, the first protective member 41 includes a lower protective member 411 and an upper protective member 412, the upper protective member 412 is set on the top of the lower protective member 411 by screws, the lower protective member 411 and the upper protective member 412 are both provided with a gas delivery groove 417 on the opposite side, the lower protective member 411 and the upper protective member 412 are both provided with a first opening 413 and a second opening 414 on the opposite side, the first opening 413 and the second opening 414 are both communicated with the gas delivery groove 417, and the first opening 413 and the second opening 414 are respectively provided with an air inlet 416 and an air outlet 415 inside; The inner wall of the gas delivery groove 417 is provided with a gas outlet 418 and a gas inlet groove 419 which are respectively connected to the gas delivery groove 417, and the gas inlet grooves 419 on the upper and lower sides are combined to form a complete Tesla valve, and the gas outlet 418 and the gas inlet groove 419 are in a one-to-one correspondence relationship; Based on the above, the air inlet 416 is connected to the air outlet of the air pump through a pipeline. When the air pump is working, the air flow is introduced from the air inlet 416, part of the air flow moves along the direction of the air delivery groove 417, and the other part of the air flow is ejected from the air outlet 418. The ejected air flow enters the interior of the air inlet groove 419. Due to the characteristics of the Tesla valve, the air flow velocity entering the air inlet groove 419 is increased, and after the increase, it is discharged from the air outlet 415. The discharged gas can be transported to the outside of the working area through the pipeline; At the same time, the airflow flowing along the air delivery groove 417 is also discharged from the air outlet 415. During the discharge process, this part of the airflow will flow through the end of the air inlet groove 419 close to the air outlet 415. Due to the characteristics of the Tesla valve, this part of the airflow will not be unable to enter the air inlet groove 419. Instead, it will generate an air pressure difference at the end of the air inlet groove 419 close to the air outlet 415, thereby making the airflow discharged from the air inlet groove 419 flow faster. The first protective member 41 achieves the effect of preventing the airflow with stains from contacting the optical glass on the surface of the cleaning head 2 by generating an airflow (i.e., a horizontal air curtain) flowing from the air outlet 418 to the direction of the air inlet groove 419.

[0023] Embodiment 3 Based on the first embodiment, Figure 4 , Figure 9-11 As shown, the second protective member 42 includes an air guide member 421, the lower surface of the air guide member 421 is provided with an annular air guide groove 422, a partition plate 423 is provided inside the annular air guide groove 422, an air inlet pipe 425 and an air outlet pipe 426 are provided on the outer surface of the air guide member 421, the air inlet pipe 425 and the air outlet pipe 426 are both communicated with the annular air guide groove 422 and are respectively provided on both sides of the partition plate 423, and a baffle plate 424 is provided on the side of the partition plate 423 away from the air inlet pipe 425; Based on the above, the air inlet pipe 425 is connected to the air outlet end of the air pump. When the air pump is working, the air enters the annular air guide groove 422 from the air inlet pipe 425 and flows along the direction of the annular air guide groove 422, that is, an annular airflow is generated, which flows to the air outlet pipe 426 for discharge. The air outlet pipe 426 can transmit the airflow to the outside of the working area through the pipeline for discharge. The generation of the annular airflow makes the air pressure inside the annular air guide groove 422 lower than the external air pressure, and then the air at the center of the air guide member 421 is sucked into the annular air guide groove 422, thereby achieving the effect of preventing the air with stains from contacting the cleaning head 2. In the above process, the partition plate 423 and the baffle plate 424 play a role in blocking the airflow, preventing the airflow from being directly discharged from the air outlet pipe 426 , and ensuring that the airflow can flow along the direction of the annular air guide groove 422 .

[0024] Embodiment 4 Based on the first embodiment, Figure 5 , Fig.12 and Fig.13As shown, the third protective member 43 includes a gas delivery seat 431, the upper surface of the gas delivery seat 431 is provided with an exhaust groove 432 and an inner tube 435, the interior of the gas delivery seat 431 is provided with a gas delivery cavity 433, the interior of the gas delivery cavity 433 is provided with a connecting hole 438 interconnected with the exhaust groove 432, the outer surface of the gas delivery seat 431 is provided with a gas delivery pipe 434 extending to the inside of the gas delivery cavity 433, the outside of the gas delivery seat 431 is provided with an outer tube 436, and the outer surface of the outer tube 436 is provided with an outer tube suction pipe 437 extending to the inside of the outer tube 436; Based on the above, the air delivery pipe 434 is connected to the air outlet end of the air pump. When the air pump is working, the air flow is input from the air delivery pipe 434 to the inside of the air delivery cavity 433 and discharged from the exhaust groove 432. The discharged air flow moves along the inner cylinder 435 in a direction away from the air delivery seat 431. The air flow generated at this time pushes the air flow outward, so that the air with stains cannot enter the interior of the inner cylinder 435, thereby achieving the effect of protecting the cleaning head 2. In the above process, the air inlet end of the air pump is connected to the outer cylinder suction pipe 437, so that suction is generated inside the outer cylinder 436, and the polluted air is sucked into the inner part of the outer cylinder 436 and discharged to the outside of the working area through the air pump.

[0025] Embodiment 5 Based on the first embodiment, Figure 6 , Fig.14 and Fig.15 As shown, the fourth protective member 44 includes an air guide cylinder 441, a side block 442 is provided on the outer surface of the air guide cylinder 441, a movable groove 443 is provided on one side of the side block 442, a cover plate 446 is provided on one side of the movable groove 443 by screws, and a hinged tube 445 is hinged between the cover plate 446 and the side block 442; The articulated tube 445 includes a tube 4451, an articulated block 4452 is disposed outside the tube 4451, a threaded articulated shaft 4453 is disposed on one side of the articulated block 4452 close to the cover plate 446, the threaded articulated shaft 4453 penetrates through the cover plate 446 and is threadedly connected to the threaded cover 447, two rubber sealing blocks 444 are disposed inside the movable groove 443, and the rubber sealing blocks 444 are respectively disposed on the upper and lower sides of the articulated block 4452; Based on the above, the air outlet end of the air pump is connected to the hinged tube 445. When the air pump is working, the air flows from the hinged tube 445 into the interior of the air guide tube 441. The inflowing air flow is tangent to the air guide tube 441. At the same time, the air flow flows in a spiral shape along the interior of the air guide tube 441 in a direction away from the cleaning head 2. The air flow at this time is a spiral air flow. The generation of the spiral air flow causes the air at the center of the air guide tube 441 to be sucked into the interior of the spiral air flow, and is discharged from the air guide tube 441 driven by the spiral air flow, thereby achieving the effect of preventing the air with stains from contacting the cleaning head image. The articulated tube 445 cooperates with the side block 442 and the cover plate 446 so that the articulated tube 445 can rotate around the threaded articulated shaft 4453, thereby adjusting the initial inclination angle of the airflow when it enters the air guide cylinder 441, thereby adjusting the protective effect. After the angle adjustment is completed, the position of the articulated tube 445 is fixed by tightening the threaded cover 447.

[0026] The above embodiment achieves the function of protecting the optical glass by generating an air curtain above the cleaning head 2, and effectively prevents stains from adhering to the surface of the optical glass. Compared with the manual wiping method, the air curtain protection method is more effective and the effect is sufficiently stable.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
