Description

Technical Field

[0001] This invention belongs to the field of laser technology, specifically relating to a clean control and detection device and method for an integrated blow-and-suction beam combining system, which can be applied to the clean control and real-time cleanliness detection of the surface of precision optical structures in laser beam combining systems. Background Technology

[0002] Laser beam combining systems combine multiple low-brightness, low-power laser beams into a single high-brightness, high-power output using optical elements. The presence of contaminants in the beam combining system can lower the damage threshold of the optical elements, or even cause the system to fail. Therefore, critical components in the beam combining system must be kept clean, and contaminants generated during assembly and manufacturing are not allowed to adhere to their surfaces. Efficient cleaning and detection of particulate contaminants is a pressing technical challenge. Traditional methods for cleaning surface dust and particulate contaminants in optical products typically involve wiping with lint-free cloths containing toxic solvents such as alcohol or ether, supplemented by vacuuming. However, this method cannot provide real-time information on the surface cleanliness of the structure and requires post-cleaning testing with specialized particulate contaminant detection equipment. However, this detection process easily introduces new surface dust and particulate contaminants and has low cleaning efficiency.

[0003] In the prior art, patent CN 205628784 U discloses a manual crevice cleaning air gun with integrated blowing and suction. The manual crevice cleaning air gun with integrated blowing and suction uses a fan to provide the blowing and suction power. It can change its air intake and exhaust pipes through two three-way valves. By combining the functions of air intake and blowing, it is convenient to use and has a good cleaning effect on crevice. It is mainly used in construction projects or home cleaning scenarios. However, its cleaning blowing and suction ports are located on both sides of the handheld air gun, which cannot simultaneously blow and suction the cleaning surface. During the cleaning process, the blowing and suction state must be manually switched by a switch. At the same time, it is impossible to detect the degree of cleaning of contaminant particles.

[0004] In view of this, it is necessary to design a cleanliness control and detection device and method for an integrated blowing and suction beam synthesis system to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a clean control and detection device and method for an integrated blow-suction beam synthesis system that utilizes a combination of coarse and fine cleaning processes, and simultaneously performs particle contaminant detection during the fine cleaning process, so as to simultaneously achieve the functions of clean treatment and cleanliness detection.

[0006] To achieve the above-mentioned objectives, this invention provides a clean control and detection device for an integrated blowing and suction beam combining system, comprising a device housing, a blowing treatment pipe and a suction treatment pipe disposed within the device housing, and a display screen nested on the housing. The housing is provided with a dual-channel gas pipeline for blowing and suction, which communicates with the blowing treatment pipe and the suction treatment pipe respectively. A detachable clean probe is connected to the end of the dual-channel gas pipeline away from the housing. The clean probe is respectively designed with a blowing port and a suction port. The suction treatment pipe includes a coarse cleaning pipe and a fine cleaning pipe designed in parallel.

[0007] As a further improvement of the present invention, the blowing holes and the suction holes are designed in alternating rows; a suction filter for filtering air containing contaminants is provided on the end of the suction treatment pipe away from the clean probe, and a vacuum pump is connected to the side of the suction filter near the clean probe through a pipe.

[0008] As a further improvement of the present invention, the vacuum pump is connected to a coarse cleaning pipe and a fine cleaning pipe on the side away from the suction filter, and the coarse cleaning pipe and the fine cleaning pipe are connected together at the end near the clean probe by a cleaning mode switching valve.

[0009] As a further improvement of the present invention, a particle counting sensor and an air flow regulating valve are sequentially arranged on the fine cleaning pipe along the direction close to the vacuum pump. The air flow regulating valve is also partially arranged on the coarse cleaning pipe, and is used for regulating the air flow of the fine cleaning pipe and the coarse cleaning pipe, respectively.

[0010] As a further improvement of the present invention, an air intake flow sensor is provided on the air intake treatment pipe between the cleaning switching valve and the side wall of the housing.

[0011] As a further improvement of the present invention, the air blowing treatment pipeline is provided with an air blowing flow regulating valve, an air blowing flow sensor, an air blowing pump and an air blowing filter in sequence along the direction away from the clean probe.

[0012] As a further improvement of the present invention, the display screen is disposed on the upper part of the outer casing.

[0013] To achieve the above objectives, the present invention also provides a method for cleanliness control and detection of an integrated blowing and suction beam combining system, comprising the following steps:

[0014] S1. Select the appropriate cleaning probe according to the area to be cleaned and install it. Switch the cleaning mode switching valve to the coarse cleaning mode. Simultaneously adjust the blowing flow regulating valve and the inhalation flow regulating valve to adjust the blowing flow and inhalation flow to be greater than the preset flow. The blowing flow and inhalation flow are detected by the blowing flow sensor and the inhalation flow sensor and then displayed on the display screen.

[0015] S2. Place the clean probe close to the surface of the object to be cleaned. The airflow is blown out from the multiple air holes of the clean probe, raising a large number of floating dust particles. Then, the air containing pollutant particles near the surface of the object to be cleaned is drawn into the clean probe through multiple air holes.

[0016] S3. After coarse cleaning is completed, switch the cleaning mode switching valve to fine cleaning mode, and simultaneously adjust the blowing flow regulating valve and the inhalation flow regulating valve to adjust the blowing flow and inhalation flow to the preset flow.

[0017] S4. Place the cleaning probe close to the surface of the object to be cleaned. The airflow is blown out from multiple air holes of the cleaning probe, raising a large number of floating dust particles. Then, the air containing pollutant particles near the surface of the object to be cleaned is drawn into the cleaning probe through multiple air holes and enters the particle counting sensor through the fine cleaning pipeline to simultaneously detect the size and number of pollutant particles.

[0018] S5. The particle counting sensor's detection results are displayed on the screen. It stops working when the detection results meet the cleaning requirements.

[0019] As a further improvement of the present invention, the preset flow rate is 2.83 L / min.

[0020] As a further improvement of the present invention, the blowing flow rate and the suction flow rate are kept consistent during the cleaning process.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention utilizes a parallel setup of coarse and fine cleaning pipes. During the cleaning process, the coarse cleaning pipe first employs a high-flow-rate blowing and suction function to rapidly remove large particulate contaminants. Then, the fine cleaning pipe uses a fixed blowing and suction flow rate of 2.83 L / min for meticulous cleaning. This effectively improves cleaning efficiency. Furthermore, by incorporating a particle counting sensor installed on the fine cleaning pipe, the cleanliness of the cleaned surface can be monitored in real time, allowing for quantitative assessment of the cleaning effect. On one hand, this allows for adjustments to the cleaning process based on required cleanliness levels, saving manpower and resources and increasing efficiency. On the other hand, cleanliness testing is performed simultaneously with the cleaning of optical products. Compared to existing methods that require additional particle contaminant surface detection after cleaning, this avoids the introduction of new contaminants, ensuring the cleanliness of the optical product surface and offering significant potential economic and social benefits.

[0023] 2. The cleanroom probe of this invention employs an alternating row design for the air blowing and suction ports, which enables more uniform airflow distribution. Point-to-point blowing and suction avoids secondary contamination caused by airflow interference between different areas during cleaning, while also preventing airflow blockage and allowing for timely treatment of contaminants, thus improving processing efficiency. Furthermore, by controlling the blowing and suction flow rates consistently during the cleaning process, secondary contamination caused by excessive blowing flow can be avoided, as can poor cleaning results caused by excessive suction flow suppressing the blowing effect.

[0024] 3. The detachable design of the clean probe and the configuration of matching probes with different structures of the present invention make the high-efficiency blowing and suction integrated particulate contaminant cleaning and detection device applicable to different scenarios such as clean planes, holes, and gaps. According to different usage scenarios, the corresponding clean probes can be matched to effectively improve cleaning efficiency. Attached Figure Description

[0040] Example 1

[0041] This embodiment provides a method for cleanliness control and detection of an integrated blow-suction beam combining system, including the following steps:

[0042] S1. Select according to the area to be cleaned. Figure 2 Install the cleaning probe shown, switch the cleaning mode switching valve 52 to the coarse cleaning mode, and simultaneously adjust the blowing flow regulating valve 41 and the inhalation flow regulating valve 552 to adjust the blowing flow and inhalation flow to greater than 2.83 L / min. The blowing flow and inhalation flow are detected by the blowing flow sensor 42 and the inhalation flow sensor 51 and then displayed on the LCD screen 31.

[0043] S2. Place the clean probe 10 about 2mm above the surface of the object to be cleaned. Under the action of the air pump 43, the outside air is filtered by the air filter 44 to form an airflow, which is then transported to the clean probe 10 through the pipeline. The airflow is blown out through the multiple air holes 11 of the clean probe 10, raising a large number of floating dust particles. Then, the air containing pollutant particles near the surface of the object to be cleaned is drawn into the clean probe 10 through the multiple air intake holes 12. Finally, the air is discharged after being processed by the coarse cleaning pipeline 56 branch, vacuum pump 53 and air intake filter 54.

[0044] S3. When there are no obvious contaminants on the surface of the object to be cleaned, the coarse cleaning is completed. Switch the cleaning mode switching valve 52 to the fine cleaning mode, and simultaneously adjust the blowing flow regulating valve 41 and the suction flow regulating valve 552 to adjust the blowing flow and suction flow to 2.83L / min.

[0045] S4. Place the clean probe 10 about 2mm above the surface of the object to be cleaned. The airflow is blown out from the multiple air holes 11 of the clean probe 10, which raises a large number of floating dust particles. Then, the air containing pollutant particles near the surface of the object to be cleaned is drawn into the clean probe 10 through multiple air intake holes 12. Finally, it is processed through the fine cleaning pipe 55, vacuum pump 53 and air intake filter 54 and then discharged as fresh air. The particle counting sensor 551 on the fine cleaning pipe 55 simultaneously detects the size and number of pollutant particles.

[0046] The detection results of particle counting sensor S551 are displayed on LCD screen 31. The surface cleanliness level is classified according to GB / T25915.9-2018. The operation stops when the detection results meet the cleanliness requirements.

Figure 4 The clean probe 10 shown performs a clean treatment on the gap. The remaining steps are the same as in Example 1, and will not be repeated here.

[0049] In summary, the cleaning control and detection device and method for the integrated blowing and suction beam synthesis system disclosed in this invention, through the parallel arrangement of the coarse cleaning pipe 56 and the fine cleaning pipe 55, allows for the rapid treatment of large particulate contaminants during the cleaning process. First, the coarse cleaning pipe 56 utilizes a high-flow blowing and suction function to quickly remove large particulate contaminants. Then, the fine cleaning pipe 55 uses a fixed blowing and suction flow rate of 2.83 L / min for meticulous cleaning, effectively improving cleaning efficiency. Simultaneously, by utilizing the particle counting sensor 551 installed on the fine cleaning pipe 55, the cleanliness of the cleaned surface can be monitored in real time, allowing for quantitative judgment of the contaminant cleaning effect. On one hand, cleaning adjustments can be made according to the required cleaning level, saving manpower and resources and improving cleaning efficiency. On the other hand, cleanliness detection is performed simultaneously with the cleaning of optical products. Compared to existing methods that require additional particle contaminant surface detection after cleaning, this avoids the introduction of new contaminants, ensuring the cleanliness of the optical product surface, and possesses significant potential economic and social benefits. Furthermore, the alternating row design of the air blowing holes 11 and suction holes 12 in the cleanroom probe 10 ensures a more uniform airflow distribution. Point-to-point blowing and suction avoids secondary contamination caused by airflow interference between different areas during cleaning, while also preventing airflow blockage and allowing for timely treatment of contaminants, thus improving processing efficiency. Simultaneously, by controlling the consistent blowing and suction flow rates during the cleaning process, secondary contamination caused by excessive blowing flow and poor cleaning results due to excessive suction flow suppressing the blowing effect can be avoided.
