Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning device. Background Technology

[0002] Dry ice cleaning equipment is a type of cleaning machine. The cleaning system uses high-pressure air to spray dry ice particles onto the surface of the object being cleaned. The physical reaction caused by the temperature difference causes different substances to detach at different contraction rates. It typically consists of a main body, piping, and a spray gun. The main body generates an airflow of dry ice particles, which flows through the piping to the spray gun. Operators can directly spray the material with the handheld spray gun, quickly and easily completing the cleaning process.

[0003] In the aforementioned cleaning methods, on the one hand, the open cleaning environment typically introduces external factors such as temperature, humidity, and particulate matter, which directly or indirectly affect the cleanliness and even the performance of the materials. For example, excessively high or low ambient temperatures may affect the size of the dry ice particles in the dry ice granule airflow; large dry ice particles may damage the materials, while small particles may result in incomplete cleaning. Furthermore, high concentrations of external dust particles may cause dust to fall back during the cleaning process, leaving dust adhering to the material surface after cleaning. Additionally, excessively high ambient humidity may cause condensation on the material surface, affecting the cleaning effect and potentially impacting material properties. On the other hand, manually controlling the spray trajectory of the spray gun may lead to uneven cleaning. For instance, some areas may only require one spray, while others may require multiple sprays, and some areas may not even be sprayed at all, thus affecting the cleaning effect.

[0004] Therefore, there is an urgent need for a cleaning device that can improve the cleanliness of the cleaning material while protecting it. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In the dry ice cleaning process, dry ice particles are sprayed onto the material. When the -78°C dry ice particles come into contact with the dirt surface, they undergo embrittlement and explosion, causing the dirt to shrink and loosen. The dry ice particles then instantly vaporize and expand 800 times, generating a powerful peeling force that quickly and thoroughly removes the dirt from the object's surface, achieving a fast, efficient, safe, and energy-saving cleaning effect. The carbon dioxide used in dry ice cleaning comes from industrial waste gas and high-altitude air separation; dry ice cleaning itself does not produce carbon dioxide.

[0042] In related technologies, cleaning materials in an open environment can lead to dust settling on the material surface due to high concentrations of particulate matter in the air, resulting in incomplete cleaning. The characteristics of dry ice particle airflow also dictate that temperature directly affects the particle size, thus impacting the cleanliness of the material. Furthermore, the characteristics of dry ice particle airflow mean that the temperature drops sharply within the airflow's range, causing moisture in the environment to condense. This condensation can affect not only the cleanliness of semiconductor devices but also material properties, potentially leading to unreliability or failure of electrical materials or components within semiconductor devices. Conversely, if the ambient humidity is too low, static electricity generated on the material surface during dry ice particle airflow cleaning can cause dust to instantly adhere after cleaning, affecting the cleaning effect.

[0043] In view of this, embodiments of this application provide a cleaning device to solve the above-mentioned problems, such as... Figure 1 The diagram shown is a structural schematic of a cleaning device provided in an embodiment of this application. The cleaning device 100 includes a control unit 103, a cleaning unit 102, and an air outlet unit 101 arranged sequentially from a first side to a second side. The first side and the second side are opposite sides. The control unit 103 is electrically connected to the cleaning unit 102 and the air outlet unit 101, respectively, and includes:

[0044] The control unit 103 is used to, when it detects that there is material in the cleaning unit 102, acquire the material information of the material, acquire the corresponding set cleaning environment according to the material information, and control the air outlet unit 101 to construct the set cleaning environment in the cleaning chamber of the cleaning unit 102. The cleaning chamber is used to contain the material. The set cleaning environment includes a preset humidity range, a preset value of particulate matter concentration, and a preset value of dew point.

[0045] The air outlet unit 101 is used to fill the cleaning chamber of the cleaning unit 102 with a first gas and a second gas to create a set cleaning environment. During the cleaning process, the set cleaning environment is maintained based on the control of the control unit 103. The first gas is used to protect the material, and the second gas is used to regulate the humidity inside the cleaning chamber.

[0046] The cleaning unit 102 is used to clean the material until it meets the cleanliness standards of the material.

[0047] In one embodiment, the control unit 103 may be equipped with a controller with control logic, or a PLC (programmable logic controller) may be provided to control the relationship between the first gas and the second gas outlet rates in the air outlet unit 101, and to control the cleaning position of the material in the cleaning unit 102, the running trajectory of the cleaning spray gun, and other related data.

[0048] In one embodiment, the cleaning unit 102 may be equipped with a robotic arm, a material support, a conveying device, etc. The cleaning unit 102 can use the conveying device to place the material on the material support and use the robotic arm to hold the spray gun to clean the material.

[0049] In one embodiment, the cleaning unit 102 may be equipped with a camera, which is electrically connected to the control unit 103 and transmits video data to the control unit 103 so that the control unit 103 can confirm the materials and material information.

[0050] In one embodiment, the air outlet unit 101 may be equipped with a humidity treatment device, a filter device, and a drying device, etc., for treating the first gas and / or the second gas to be input into the cleaning chamber.

[0051] In one embodiment, the cleaning device 100 may also include an information input device, which may be a computer with a keyboard or touch screen (which may also be used to display relevant data), or a data receiving interface (such as a USB interface). The control unit 103 may include an electrical control cabinet and a snow cleaning machine. Accordingly, the snow cleaning machine may be equipped with relevant data on the cleaning components. The electrical control cabinet may be equipped with a logic control chip, which may include setting the cleaning environment and related logic for building and maintaining the set cleaning environment. The cleaning-related data in the snow cleaning machine, as well as the set cleaning environment and its related logic, can be input from the information input device.

[0052] In one embodiment, the material may be a printed circuit board, a chip, a packaged device, petrochemical-related equipment (such as a fan, air compressor, smoke machine, steam turbine, blower), or related equipment or components in the printing industry (such as gears, guide rails, nozzles contaminated with ink). There are no specific restrictions on the materials that the cleaning equipment can clean, and they can be set as needed.

[0053] In one embodiment, the material information can be determined by referencing factors such as the precision grade and volume of the device. For example, the type information can be first-class precision device, second-class precision device, 1-5cm. 3 The device, 5-10cm 3The device can be determined by the type of material itself, such as chip materials, blower materials, gear materials, etc. There are no restrictions on the specific material information here, and it can be set as needed. For example, the material information can also be the QR code or other marking information on the surface of the material.

[0054] In one embodiment, the cleaning environment can be determined based on information such as the volume, properties, and type of the material. For example, the humidity of the cleaning environment where the film product is located needs to be within a certain range to prevent surface condensation caused by humidity exceeding the highest value in the range, or film cracking caused by humidity falling below the lowest value in the range.

[0055] In one embodiment, the cleaning environment can be set based on modeling the material properties of the material.

[0056] In one embodiment, the preset humidity range is set based on the premise that the material, under certain humidity conditions, will not generate static electricity and will not affect the material's properties or the cleaning effect. In other words, to prevent the surface of the cleaned material from attracting dust due to static electricity after exiting the equipment, thus preventing re-contamination, and to prevent damage to the material and impact on the cleaning effect caused by excessive or insufficient humidity, the humidity within the cleaning chamber can be maintained within the preset humidity range. This ensures that the material surface does not generate static electricity, prevents re-contamination after exiting the equipment, and prevents damage to the material and incomplete cleaning.

[0057] In one embodiment, the first gas may be carbon dioxide or nitrogen, and the second gas may be air or carbon dioxide gas with a certain humidity.

[0058] The aforementioned equipment includes a control unit, a cleaning unit, and an air outlet unit. The control unit controls the air outlet unit and the cleaning unit to create and maintain a set cleaning environment and clean the materials. This achieves a complete and controllable cleaning environment and process, enabling fully automated and precise control of the cleaning process. It solves the problems of poor cleanliness and potential material damage caused by cleaning in open environments in related technologies, and enables rapid and efficient cleaning of materials under precise control in a Class 100 clean environment.

[0059] Based on the above Figure 1 The present application provides a cleaning unit 202 in a cleaning device, such as a cleaning device. Figure 2 As shown, the cleaning chamber of the cleaning unit 202 is equipped with a detection subunit 2021 (not shown in the figure), a material conveying device 2022, a cleaning fixture 2023 and a spray gun 2025.

[0060] The detection subunit 2021 is electrically connected to the control unit 201 and is used to detect environmental data in the cleaning chamber and feed the environmental data back to the control unit 201 so that the control unit 201 controls the air outlet unit 203 to build or maintain the set cleaning environment.

[0061] The material conveying device 2022 is electrically connected to the control unit 201 and is used to convey materials to a set cleaning position under the control of the control unit 201.

[0062] The cleaning fixture 2023 is electrically connected to the control unit 201 and is used to control the clamped spray gun 2025 to clean the material under the control of the control unit 201.

[0063] In one embodiment, the cleaning chamber can be as follows: Figure 2 As shown, the cleaning unit 202 is a space for accommodating the detection subunit 2021, the material conveying device 2022, the cleaning fixture 2023, the spray gun 2025, and the material.

[0064] In one embodiment, the detection subunit 2021 may include at least one of a dew point meter, a particle tester, and a humidity tester. The detection subunit 2021 may be set within a predetermined distance range that does not affect cleaning and is close to the material, in order to ensure the acquisition of accurate environmental data and the accuracy of cleaning environment control.

[0065] In one embodiment, the material conveying device 2022 may be a cleanroom conveyor belt or a robotic arm, etc., used to convey or grab materials to a set cleaning position. The specific configuration of the material conveying device 2022 is not limited here.

[0066] In one embodiment, the cleaning fixture 2023 may include a three-axis module, or it may be a robotic arm, which controls the clamped spray gun to clean the surface of the material.

[0067] Based on the above Figure 1 , 2 The present application provides a cleaning unit 202 in the cleaning equipment, which is equipped with an ion fan 2024 for blowing ion air onto the material.

[0068] In one embodiment, the ion blower 2024 can be installed in the cleaning chamber, and the outlet of the ion blower 2024 is directed toward the material to blow ion air onto the material to eliminate static electricity on the surface of the material.

[0069] Based on the above Figure 2The present application provides a detection subunit 2021 in the cleaning equipment, which includes at least one dew point meter, at least one particle tester and at least one humidity tester; the dew point meter is used to detect the dew point in the cleaning chamber; the particle tester is used to detect the concentration of particulate matter in the cleaning chamber; and the humidity tester is used to detect the humidity in the cleaning chamber.

[0070] In one embodiment, there are no restrictions on the specific location and number of the dew point meter, particle tester, and humidity tester. The dew point meter, particle tester, and humidity tester can be set within a set distance from the material to obtain more accurate data on dew point, particulate matter concentration, and humidity. Alternatively, to accommodate the variability in material volume, the dew point meter, particle tester, and humidity tester can be set on the wall of the cleaning chamber.

[0071] Based on the above Figure 1 In the cleaning equipment described in this application embodiment, a cleaning unit 302 is provided in the cleaning equipment, such as... Figure 3 As shown, the cleaning unit 302 also includes an inlet transition chamber 3021 and an outlet transition chamber 3022.

[0072] The inlet transition chamber 3021 is electrically connected to the control unit 301. The inlet transition chamber 3021 has a sealed state and a state in communication with the cleaning chamber, and is used to receive materials. In the sealed state, the control unit 301 controls the inlet transition chamber 3021 to perform vacuum treatment. In the state in communication with the cleaning chamber, the materials are transferred into the cleaning chamber.

[0073] The outlet transition chamber 3022 is electrically connected to the control unit 301 and is used to receive the cleaned material from the cleaning chamber. Under the control of the control unit 301, the cleaned material is purged.

[0074] In one embodiment, the inlet transition chamber 3021 and the outlet transition chamber 3022 each have a transmission device, which can be connected to a material conveying device to realize the transmission of material from the inlet transition chamber 3021 to the cleaning chamber, and after cleaning, the material is transmitted to the outlet transition chamber 3022 and then taken out.

[0075] In one embodiment, the air outlet unit 303 can be connected to the purge gas pipeline of the outlet transition chamber 3022. When the outlet transition chamber 3022 contains material, the control unit 301 controls the air outlet unit 303 to blow the first gas to the material through the purge gas pipeline to further ensure the cleanliness of the material.

[0076] In one embodiment, the control unit 301 may also be equipped with a vacuum pumping device to evacuate the inlet transition chamber 3021 when there is material in the inlet transition chamber 3021.

[0077] In one embodiment, the inlet transition chamber 3021 and the outlet transition chamber 3022 are respectively equipped with their own pressure gauges to detect the pressure in the inlet transition chamber 3021 so that the control unit 301 can perform vacuum control on the inlet transition chamber 3021, and to detect the pressure in the outlet transition chamber 3022 so that the control unit 301 can perform purging control on the outlet transition chamber 3022.

[0078] In one embodiment, an inlet shut-off valve is provided between the inlet transition chamber 3021 and the cleaning chamber. This valve is used to cut off the connection between the inlet transition chamber 3021 and the cleaning chamber during vacuuming, ensuring the inlet transition chamber 3021 is sealed. After vacuuming, the inlet shut-off valve can be opened, allowing the inlet transition chamber 3021 to communicate with the cleaning chamber, enabling material transfer to the cleaning chamber. The valve is then closed to maintain the sealing of the cleaning chamber. An outlet shut-off valve is provided in the outlet transition chamber 3022. During cleaning, the outlet shut-off valve cuts off the outlet transition chamber 3022 from the cleaning chamber, preventing particles detached from the cleaning material in the cleaning chamber from entering the outlet transition chamber 3022. After cleaning, the outlet shut-off valve is opened to transfer material to the outlet transition chamber 3022, and then closed again for purging in the outlet transition chamber 3022.

[0079] Based on the above Figure 2 , 3 In the cleaning equipment, this application embodiment provides a control unit 401 in the cleaning equipment, such as... Figure 4 As shown, the control unit 401 includes an electrical control cabinet 4011 and a snowflake cleaning machine 4012;

[0080] The electrical control cabinet 401 is electrically connected to the detection subunit 4021, the material conveying device 4022, and the cleaning fixture 4023, respectively. It is used to control the air outlet unit 403 to build or maintain a set cleaning environment based on the environmental data detected by the detection subunit 4021; to control the material conveying device 4022 to convey materials to a set cleaning position based on the real-time position data of the material conveying device 4022; and to control the spray gun 4024 held by the cleaning fixture 4023 to clean the materials based on the running trajectory data of the cleaning fixture 4023.

[0081] The snow cleaning machine 4012 is connected to the spray gun 4024 and is used to generate and supply the spray gun 4024 with a dry ice particle airflow.

[0082] In one embodiment, the electrical control cabinet 4011 in the control unit 401 can be mounted on the outer wall of the control unit 401, such as... Figure 4As shown, this facilitates the maintenance of the electrical control cabinet 4011. Since the electrical control cabinet 4011 has many connecting wires, such as those to the dew point meter, particle tester, humidity tester, material conveying device, cleaning fixture, and air outlet unit, externalizing the electrical control cabinet 4011 onto the control unit 401 prevents the wiring from affecting the exhaust from the bottom wall of the cleaning chamber. This ensures that the bottom wall of the cleaning chamber has sufficient openings and corresponding pressure solenoid valves to control whether these openings are open for exhaust. Specifically, when the pressure solenoid valve detects that the pressure in the cleaning chamber exceeds a set pressure value, it controls the pressure solenoid valve to open, allowing exhaust from the corresponding opening.

[0083] In one embodiment, the snow cleaning machine 4012 in the control unit 401 is disposed inside the control unit 401. Figure 4 As can be seen, the pipes for the dry ice particle airflow in the snow cleaning machine can be easily connected to the spray gun, facilitating pipe installation.

[0084] In one embodiment, the control unit 401 includes a vacuum pump 4013, which is connected to the aforementioned inlet transition chamber via a pump pipe and is used to perform vacuuming on the inlet transition chamber.

[0085] Based on the above Figure 2-4 In the cleaning equipment, this application embodiment provides a control unit 501 in the cleaning equipment, such as... Figure 5 As shown, the control unit 501 includes a return air device 5015 for collecting the exhaust gas discharged from the cleaning chamber.

[0086] In one embodiment, the return air device 5015 transmits the waste gas collected from the cleaning chamber to the outlet air unit 503 through the return air duct. The outlet air unit 503 then processes the waste gas to obtain the first gas, thus enabling the recycling of the waste gas.

[0087] In one embodiment, an exhaust solenoid valve 5022 may be installed on the return air duct. When the pressure in the return air duct exceeds a pressure threshold, the exhaust solenoid valve 5022 will exhaust the air.

[0088] In one embodiment, at least one reserved wiring port may be provided on the side wall of the cleaning unit 502 for connecting power cords, data lines, etc. to the cleaning unit 502, such as the connection lines between the electrical control cabinet 5011 and the dew point meter, particle tester and humidity tester, the connection lines between the electrical control cabinet 5011 and the material conveying device and the cleaning fixture, etc.

[0089] In one embodiment, the vacuum pump 5013 can be located between the electrical control cabinet 5011 and the snow cleaning machine 5012, and the snow cleaning machine 5012 can be equipped with a filter to filter out dust particles in the external gas-propulsion gas collected by the snow cleaning machine 5012.

[0090] In one embodiment, Figure 5 The cleaning equipment shown can also be equipped with a display device 504 to display relevant data in the cleaning equipment and input or update relevant parameters, such as the material information of the material corresponding to the set cleaning environment, the running trajectory of the spray gun, the particle and airflow velocity data of the dry ice particle airflow, and the airflow related data of the air outlet unit 503.

[0091] Based on the above Figure 1-5 This application provides an air outlet unit 600 for a cleaning device, such as a cleaning equipment and related embodiments. Figure 6 As shown, the air outlet unit 600 includes an air supply pipe 605, a filter 606 (not shown in the figure), and a dryer 607 (not shown in the figure). The filter 606 and the dryer 607 are disposed in the air supply pipe 605, with the filter 606 disposed on the air inlet side of the air supply pipe 605 relative to the dryer 607, and the dryer 607 disposed on the air outlet side of the air supply pipe 605 relative to the filter 606.

[0092] Based on the above Figure 6 The present application provides an air outlet unit 600 for a cleaning device, which includes a gas separation device 604 (not shown in the figure). The gas separation device 604 is connected to the return air device in the control unit through a return air duct, and is used to extract a first gas from the exhaust gas in the return air duct.

[0093] In one embodiment, when the cleaning equipment is placed vertically to the ground, the filter in the air supply pipeline is installed above the dryer. The vertical projections of the filter and the dryer do not necessarily overlap completely and can be specifically configured according to the shape of the air supply pipeline. In this way, the first gas separated from the exhaust gas and the first gas generated from other gas sources can be transported from the air supply pipeline to the cleaning chamber. The first gas passes through the filter to remove particulate matter before passing through the dryer. Compared to passing through the dryer first, which results in the dryer consuming more power to dry the particulate matter, the air outlet unit in this application can reduce power consumption and save costs.

[0094] In one embodiment, the air outlet unit 600 may also be equipped with a manual solenoid valve 601. When the pressure sensor 604 determines that the pressure in the air outlet unit 600 exceeds the preset pressure value and the cleaning equipment is powered off, the manual solenoid valve 601 is used for venting to maintain the pressure of the air outlet unit 600 in accordance with the pressure requirements.

[0095] In one embodiment, the air outlet unit 600 may also be equipped with a humidity sensor 602, which can adjust the power of the dryer according to the humidity data of the humidity sensor 602. This adjustment can be made by the control unit or manually.

[0096] In one embodiment, the air outlet unit 600 may also be provided with a reserved wiring port 603, which can be used to connect the data line and / or power line of the functional module to the electrical control cabinet or power supply when the air outlet unit needs to add functions or integrate the corresponding functional module.

[0097] It should be noted that the cleaning equipment and related embodiments illustrated in this application are only used to illustrate the solution. Changes in the shape of each component, the number of components, and the addition or subtraction of components related to conventional functions should all be within the scope of the claims of this application and their equivalents. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
