Description

Technical Field

[0001] This invention relates to the field of cleanroom technology, and in particular to a combined dust removal and air shower system and method. Background Technology

[0002] The electronics manufacturing industry has high requirements for the cleanliness of the production environment. The existing solution uses air showers to deal with dust brought in by external personnel. However, it is difficult to supervise each employee to clean themselves in the air shower according to the standard procedure. The cleaning effect depends entirely on the employee's self-discipline. In addition, each employee has a different body shape, especially their appearance and volume after wearing cleanroom clothing. This results in certain differences in the effectiveness of air shower dust removal.

[0003] In terms of factory management, it is difficult to establish dust removal status for each employee. When setting air shower dust removal parameters (such as duration, channel length, etc.), there is a lack of effective reference basis, and settings can only be made according to industry-standard practices, which often leads to poor dust removal effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, a combined dust removal and air shower system and method are provided, aiming to solve the technical problems mentioned in the background.

[0005] A linked dust removal and air shower system includes a first space and a second space arranged sequentially. The first space includes a guide unit, an identification unit, and a body processing unit arranged sequentially. The guide unit guides personnel to be dusted in sequence. The identification unit identifies the personnel's identity information. The body processing unit removes dust from cleanroom garments and collects body parameters. The end of the body processing unit away from the identification unit is connected to the second space. The second space includes a sealed channel and a fixed guide area and a variable guide area arranged sequentially within the sealed channel. The top of the sealed channel is provided with several air shower components. Several indicator components are spaced apart within the variable guide area. A monitoring and calibration device and a central processing unit are respectively provided on the side of the variable guide area away from the fixed guide area. The monitoring and calibration device monitors and calibrates the personnel to be dusted. The central processing unit is communicatively connected to the identification unit, the body processing unit, the air shower components, the indicator components, and the monitoring and calibration device.

[0006] The beneficial effects of this invention are: Through the linkage of the identification unit, the volume processing unit, and the central processing unit, the system can dynamically adjust the processing flow (e.g., air shower intensity and duration) based on personnel identity information (such as access level and job requirements), avoiding a "one-size-fits-all" approach. The identification unit collects identity information, and the volume processing unit collects volume parameters, which are recorded by the central processing unit to form a traceable cleanroom management file, facilitating subsequent quality analysis or problem tracing. While removing dust, the volume processing unit collects key volume parameters (such as personnel volume and maximum contact area). Combined with real-time feedback from the monitoring and calibration device, the central processing unit can automatically provide information via the indicator component. The variable guidance zone minimizes human intervention in the movement path. The first space's volume processing unit pre-dusts the cleanroom garments, while the second space uses a segmented process of fixed guidance zone (basic air shower) and variable guidance zone (dynamic enhanced air shower) to achieve step-by-step filtration from coarse to fine dust removal, ensuring the compliance rate of personnel entering the high-cleanliness area. Through modular linkage design, dynamic parameter optimization, and intelligent decision-making mechanisms, the system achieves efficient collaboration throughout the entire process from personnel identification to cleanroom treatment, taking into account cleanliness control, resource conservation, and operational safety, making it suitable for the increasingly stringent cleanroom requirements of the electronics manufacturing industry.

[0007] Furthermore, the identification unit and the body processing unit are located inside the passage fence, and the two opposite ends of the passage fence are respectively provided with a first one-way door and a second one-way door. The first one-way door is located between the guiding unit and the identification unit, and the second one-way door is adjacent to the entrance of the second space.

[0008] Furthermore, the identification unit includes a first support rod and a facial recognition device and a magnetic card recognition device disposed on the first support rod from top to bottom.

[0009] Furthermore, the body processing unit includes a first support member, a first body dust removal member, and a first body sensing member. The first body dust removal member includes a first fan-shaped body and a first dust-adhesive layer stacked together. The first support member is connected to the side of the first fan-shaped body facing away from the first dust-adhesive layer. The first body sensing member is disposed on the top of the first fan-shaped body or between the first fan-shaped body and the first dust-adhesive layer. The first body sensing member is used to detect the body parameters of the person.

[0010] Furthermore, a bottom processing unit is provided between the second space and the body processing unit, the bottom processing unit including a dust-adhesive mat disposed on the ground inside the passage fence.

[0011] Furthermore, a first airtight door and a second airtight door are respectively provided at opposite ends of the sealed channel. The first airtight door is located on the side of the fixed guide area away from the variable guide area, and the second airtight door is located on the side of the variable guide area assembly away from the fixed guide area assembly.

[0012] Furthermore, the fixed guide area includes a plurality of spaced-apart fixed plates, with adjacent fixed plates extending toward each other, one end of an adjacent fixed plate facing away from the other fixed plate being connected to one side wall of the sealed channel, and one end of an adjacent fixed plate facing toward the other fixed plate extending toward the other side wall of the sealed channel, forming a gap.

[0013] Furthermore, the indicating component includes a first lighting device and a second lighting device, which are respectively disposed on the side wall of the sealed passage and the second lighting device is disposed on the ground of the sealed passage.

[0014] The present invention also provides a method for coordinated dust removal and air showering, wherein the method employs the coordinated dust removal and air showering system described above, and the method includes the following steps: A single person enters the first space through the guidance unit, and the identification unit collects the person's identity information and uploads the identity information to the central processing unit; The body processing unit removes dust from the cleanroom suits of the personnel and collects body parameters, then uploads the body parameters to the central processing unit. The central processing unit obtains a preset number of air showers based on a preset algorithm and the body parameters. The central processing unit assigns a tag to the identity information, the body parameters, and the preset number of air showers, and stores them in a mapping manner. When the personnel enter the sealed passage of the second space, and when the personnel pass through the fixed guide area and reach the variable guide area, a fixed air shower is performed in the fixed guide area, and the fixed air shower corresponds to a fixed number of air showers. The central processing unit uses the monitoring and calibration device to calibrate the personnel with the tag. The central processing unit subtracts the preset number of air showers from the fixed number of air showers to obtain the remaining number of air showers. The central processing unit determines the remaining number of air showers. If the remaining number of air showers is 0, the central processing unit controls the indicator component adjacent to the person to emit a first color light, and the person moves along a first route. If the remaining number of air showers is not 0, the central processing unit controls the indicator component adjacent to the person to emit a second color light, and the person moves along a second route. After each person passes an indicator component, the central processing unit decrements the remaining number of air showers by 1 to obtain the final remaining number of air showers. The central processing unit then determines the final remaining number of air showers. If the final remaining number of air showers is 0, the central processing unit controls the adjacent indicator component to emit a first color light, and the person proceeds along a first route. If the final remaining number of air showers is not 0, the central processing unit controls the adjacent indicator component to emit a second color light, and the person proceeds along a second route. The central processing unit controls the monitoring and calibration device to perform visual image tracking of the personnel and uploads the acquired images to the central processing unit until the personnel leave the second space.

[0017] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Furthermore, the various embodiments of the invention, the features within those embodiments, and the features of the embodiments may be freely combined without obvious conflict or contradiction.

[0020] Example 1 like Figure 1-4As shown, a linked dust removal and air shower system includes a first space 1 and a second space 2 arranged sequentially. The first space 1 includes a guide unit 11, an identification unit 12, and a body processing unit 13 arranged sequentially. The guide unit 11 guides personnel to be dusted in sequence, the identification unit 12 identifies the identity information of the personnel, and the body processing unit 13 removes dust from the cleanroom suit and collects body parameters. The end of the body processing unit 13 away from the identification unit 12 is connected to the second space 2. The second space 2 includes a sealed channel 21 and a system within the sealed channel 21... The system consists of multiple fixed guide zones 22 and multiple variable guide zones 23. Multiple air shower components 24 are located at the top of the enclosed passage 21. Multiple indicator components 231 are spaced apart within the variable guide zones 23. A monitoring and calibration device 25 and a central processing unit 26 are located on the side of the variable guide zone 23 furthest from the fixed guide zones 22. The monitoring and calibration device 25 monitors and calibrates the personnel to be cleaned. The central processing unit 26 is communicatively connected to the identification unit 12, the body processing unit 13, the air shower components 24, the indicator components 231, and the monitoring and calibration device 25. The personnel to be cleaned are guided into the first space 1 (pre-processing stage) by the guidance unit 11. The identification unit 12 is then triggered, and the central processing unit 26 verifies their identity information. If the identity verification is successful, the body processing unit 13 is triggered to prepare. If the identity verification fails, an alarm or prompt may be issued using existing alarm or prompt devices for re-verification. The body processing unit 13 performs preliminary dust removal on the cleanroom suit and simultaneously collects personnel body parameters. The data is uploaded to the central processing unit 26 in real time for dynamic adjustment of the subsequent air shower strategy. Upon entering the second space 2 (dynamic air shower stage), when personnel enter through the sealed passage 21 and pass through the fixed guide area 22 to reach the variable guide area 23, the central processing unit 26 predicts the air shower demand in the variable guide area 23 based on the parameters collected by the volume processing unit 13, and generates a personalized travel path through the indicator component 231. The air shower component 24 blows air onto the personnel on the travel path, and the monitoring and calibration device 25 tracks the personnel's position in real time.

[0021] Specifically, the identification unit 12 and the body processing unit 13 are located inside the passageway enclosure 14. At opposite ends of the passageway enclosure 14 are a first one-way door 141 and a second one-way door 142. The first one-way door 141 is located between the guide unit 11 and the identification unit 12, and the second one-way door 142 is adjacent to the entrance of the second space 2. After passing through the guide unit 11, personnel enter the passageway enclosure 14 through the first one-way door 141, ensuring that personnel move in a one-way queue. Then, the identification unit 12 performs identity verification, and the body processing unit 13 cleans the cleanroom garment and collects body parameters. At this point, personnel who need to leave the passageway enclosure 14 without entering the second space 2 can exit through the second one-way door 142.

[0022] Specifically, the identification unit 12 includes a first support rod 121 and a facial recognition device 122 and a magnetic card recognition device 123 mounted on the first support rod 121 from top to bottom. Personnel undergoing dust removal are identified using either the facial recognition device 122 or the magnetic card recognition device 123. For internal employees, the magnetic card recognition device 123 can be used for identification; for external personnel, the facial recognition device 122 can be used. Of course, for personnel whose faces are obscured by wearing dustproof clothing, the magnetic card recognition device 123 is used for identification.

[0023] Specifically, the volume processing unit 13 includes a first support member 131, a first volume dust removal member 132, and a first volume sensing member 133. The first volume dust removal member 132 includes a stacked first fan-shaped body 1321 and a first adhesive layer 1322. The first support member 131 is connected to the side of the first fan-shaped body 1321 facing away from the first adhesive layer 1322. The first volume sensing member 133 is disposed on the top of the first fan-shaped body 1321 and is used to detect the volume of the person. It should be noted that the person wearing the cleanroom suit presses each side of their body onto the first adhesive layer 1322 by turning around, for example, rotating in the order of back-left-front-right. By pressing and peeling, the first adhesive layer 1322 can evenly contact each side of the body. The first body sensing element 133 detects the volume of the person when they perform the above actions. The first body sensing element 133 is a width sensor (infrared or laser sensor). It calculates the volume of the person by collecting the width of each side of the person. It should be noted that the volume of the person refers to the external volume, that is, the overall volume of the person after wearing the cleanroom suit (considering that the cleanroom suit itself has an expansion effect, and the purpose of dust removal is to remove dust from the cleanroom suit). For example, if the values ​​collected in the order of back-left-front-right are 750mm, 350mm, 700mm, and 360mm respectively, then the calculated volume parameter (person's volume) T = W1max * W2max * H = 750 * 360 * H, where H is the standard height parameter, which can be taken as 1700mm, or a height sensor can be used for additional collection. W1max is the largest value among the width values ​​collected from the front and back, and W2max is the largest value among the width values ​​collected from the left and right sides.

[0024] Specifically, a bottom treatment unit 15 is provided between the second space 2 and the body treatment unit 13. The bottom treatment unit 15 includes a dust-removing mat 151 placed on the ground inside the passageway fence 14. Personnel to be dusted remove dust from the soles of their shoes by stepping on the dust-removing mat 151.

[0025] Specifically, a first airtight door 211 and a second airtight door 212 are respectively provided at opposite ends of the sealed passage 21. The first airtight door 211 is located on the side of the fixed guide area 22 away from the variable guide area 23, and the second airtight door 212 is located on the side of the variable guide area 23 away from the fixed guide area 22. By providing the first airtight door 211 and the second airtight door 212, the airtight doors of the air shower in the prior art can be used, which can be opened by sliding or opening, and are equipped with rubber strips around the perimeter for airtightness, so that the second space 2 forms a sealed space.

[0026] Specifically, the fixed guide area 22 includes multiple spaced-apart fixed plates 221. Adjacent fixed plates 221 extend towards each other. One end of an adjacent fixed plate 221 facing away from the other is connected to one side wall of the sealed passage 21. The other end of an adjacent fixed plate 221 facing the other extends towards the other side wall of the sealed passage 21, forming a gap. In this embodiment, the length of the fixed plate 221 is less than the width of the sealed passage 21. The difference between its length and the passage space is sufficient to allow one person to pass through, for example, the difference can be 60-80cm. Its height is sufficient to block people so that they can move in the guide direction and prevent people from turning over from above or below, so the height can be 30-70cm. The fixed plates 221 extend towards each other, dividing the enclosed passage 21 into a turnaround passage. When passing through, personnel are restricted by the fixed guide area 22 and move in an S-shape. At least one air outlet (not shown) is provided on both sides of the enclosed passage 21 in the S-shaped passage. The air outlet is connected to the air shower assembly 24 through a pipe to blow the personnel.

[0027] Specifically, the indicator component 231 includes a first lighting device 231 and a second lighting device 2312. The first lighting device 2311 is located on the side wall of the enclosed channel 21, and the second lighting device 2312 is located on the ground of the enclosed channel 21. In this embodiment, both the first lighting device 2311 and the second lighting device 2312 include a light source and a housing. The difference is that the second lighting device 2312 also has a column support below the housing. The light source is located inside the housing, which can be transparent or partially transparent to allow light to pass through. The light source has at least a color-changing function, such as using dual-color or multi-color LED beads or color-changing LED beads. The housing can also have a light outlet, such as a narrow slit-shaped light outlet, so that the light from the light source can be emitted from the light outlet without obstruction. In this case, a light source with strong penetrability can be selected, such as laser beads or high-brightness beads. If conditions permit, a surface-shaped light surface emitted from the light outlet can be seen, which is even better. The second lighting device 2312 is installed on the ground of the enclosed passage 21 and has a certain gap from the side wall of the enclosed passage 21, allowing only one person to pass through at a time, for example, a gap of 60-80cm.

[0028] It should be noted that, as Figure 2 As shown, dashed and solid lines are provided within the variable guide zone 23, corresponding to the first route and the second route, respectively. When a single person reaches the variable guide zone 23 from the fixed guide zone 22, the central processing unit 26 subtracts the preset number of air showers from the fixed number of air showers to obtain the remaining number of air showers. The remaining number of air showers is then judged. If the remaining number of air showers is zero, the first lighting device 2311 and the second lighting device 2312 adjacent to the person simultaneously emit a first-color light, and the person passes through the variable guide zone 23 along the first route and exits the second space 2. If the remaining number of air showers is not zero, the first lighting device 2311 and the second lighting device 2312 adjacent to the person simultaneously emit a second-color light, and the person passes through the variable guide zone 23 along the first route and exits the second space 2. As the person travels along the second route, after each of the indicator components 231, the central processing unit 26 decrements the remaining number of air showers by 1 to obtain the final number of air showers. The central processing unit 26 then determines the final number of air showers. If the final number of air showers is zero, the first lighting device 2311 and the second lighting device 2312 adjacent to the person simultaneously emit a first color light, and the person travels along the first route through the variable guide area 23 and exits the second space 2. If the final number of air showers is not zero, the first lighting device 2311 and the second lighting device 2312 adjacent to the person simultaneously emit a second color light, and the person continues to travel along the second route. Subsequent travel routes are described above.

[0029] This invention, through the linkage of the identification unit 12, the body processing unit 13, and the central processing unit 26, enables the system to dynamically adjust the processing flow (e.g., air shower intensity and duration) based on personnel identity information (such as access level and job requirements), avoiding a "one-size-fits-all" approach. The identification unit 12 collects identity information, and the body processing unit 13 collects body parameters, which are recorded by the central processing unit 26 to form a traceable cleanroom management file, facilitating subsequent quality analysis or problem tracing. While removing dust, the body processing unit 13 collects key body parameters (such as personnel volume and maximum contact area). Combined with real-time feedback from the monitoring and calibration device 25, the central processing unit 26 can automatically provide the travel route within the variable guide zone 23 via the indicator component 231, reducing manual intervention. Intervention: The volume processing unit 13 in the first space 1 pre-dusts the cleanroom garments. The second space 2 uses segmented processing through a fixed guide zone 22 (basic air shower) and a variable guide zone 23 (dynamic enhanced air shower). By combining physical dust removal with dynamic air shower and real-time data-driven route adjustment, the efficiency and coverage of personnel purification in the cleanroom environment are significantly improved. This achieves step-by-step filtration from coarse dust removal to fine dust removal, ensuring the compliance rate of personnel entering high-cleanliness areas. Through modular linkage design, dynamic parameter optimization, and intelligent decision-making mechanisms, the system achieves efficient collaboration throughout the entire process from personnel identification to cleanroom treatment, taking into account cleanliness control, resource conservation, and operational safety, making it suitable for the increasingly stringent cleanroom requirements of the electronics manufacturing industry.

[0030] Example 2 like Figure 5 As shown, the present invention also provides a method for coordinated dust removal and air showering, wherein the method employs the coordinated dust removal and air showering system described above, and the method includes the following steps: S1: A single person enters the first space 1 through the guidance unit 11, and the identification unit 12 sequentially collects the person's identity information and uploads the identity information to the central processing unit 26; S2: The body processing unit 13 removes dust from the cleanroom suit of the personnel and collects body parameters, and uploads the body parameters to the central processing unit 26; S3: The central processing unit 26 obtains a preset number of air showers based on a preset algorithm and the body parameters. The central processing unit 26 assigns a tag to the identity information, the body parameters, and the preset number of air showers, and stores them in a mapping manner. S4: When the personnel enter the sealed passage 21 of the second space 2, and when the personnel pass through the fixed guide area 22 and reach the variable guide area 23, a fixed air shower is performed in the fixed guide area, and the fixed air shower corresponds to a fixed number of air showers. The central processing unit 26 uses the monitoring and calibration device 25 to calibrate the personnel and the tag. The central processing unit 26 subtracts the preset number of air showers from the fixed number of air showers to obtain the remaining number of air showers. S5: The central processing unit 26 determines the remaining number of air showers. If the remaining number of air showers is zero, the central processing unit 26 controls the indicator component 231 adjacent to the personnel to emit a first color light, and the personnel move along the first route 21. If the remaining number of air showers is not zero, the central processing unit 26 controls the indicator component 231 adjacent to the personnel to emit a second color light, and the personnel move along the second route 21. S6: After each person passes an indicator component 231, the central processing unit 26 decrements the remaining number of air showers by 1 to obtain the final number of air showers. The central processing unit 26 judges the final number of air showers. If the final number of air showers is zero, the central processing unit 26 controls the indicator component 231 adjacent to the person to emit a first color light, and the person moves along the first route 21. If the final number of air showers is not zero, the central processing unit 26 controls the indicator component 231 adjacent to the person to emit a second color light, and the person moves along the second route 21. S7: The central processing unit 26 controls the monitoring and calibration device 25 to perform image visual tracking on the n people and uploads the collected images to the central processing unit 26 until the people leave the second space 2.

[0031] Example 3 The difference from Example 1 is as follows: Specifically, such as Figure 5 As shown, the body processing unit 13 includes a second support member 134, a second body dust removal member 135, and a second body sensing member 136. The second body dust removal member 135 includes a stacked second fan-shaped body 1351 and a second adhesive layer 1352. The second body sensing member 136 is disposed between the second fan-shaped body 1351 and the second adhesive layer 1352. The second support member 134 is connected to the side of the second fan-shaped body 1351 facing away from the second body sensing member 136. The second body sensing member 136 is used to detect the contact area of ​​the person.

[0032] It should be noted that in this embodiment, the body parameter is the maximum contact area, the second body sensing element 136 is a pressure sensor, and several pressure sensor arrays are arranged on the back side of the second fan-shaped body 1351. The maximum contact area is determined by collecting the pressure parameters of each pressure sensor. The principle is as follows: when a person performs the above action, the body, including the cleanroom suit, is pressed onto the second adhesive layer 1352. The pressure sensor in contact with the pressed part will collect values ​​different from those collected by the pressure sensor of the unpressed part. The values ​​collected by the pressure sensor are then used to filter out a batch of values ​​that meet the conditions. Then, by repositioning the device that uploads these values ​​(the position coordinates of each sensing unit of the pressure sensor array are known), the maximum contact area can be calculated. Preferably, a more accurate contact area can be obtained by measuring the pressure sensor values ​​when the person peels off the garment. Since pressure sensors often use elastic force to measure pressure, the measured data is negative when the elasticity is stretched. The maximum contact area can be determined by screening the stretching values ​​that meet the conditions. This method is more accurate because the second adhesive layer 1352 can stick to the outermost edge of the cleanroom garment, so the pulling caused by the adhesive force can better reflect the maximum contact area.

A combined dust removal and blowing method, characterized in that: The method employs the linked dust removal and blowing system as described in any one of claims 1-8, and the method includes the following steps: A single person enters the first space through the guidance unit, and the identification unit collects the person's identity information and uploads the identity information to the central processing unit; The body processing unit removes dust from the cleanroom suit of the personnel and collects body parameters, and uploads the body parameters to the central processing unit; The central processing unit obtains a preset number of air showers based on a preset algorithm and the body parameters. The central processing unit assigns a tag to the identity information, the body parameters, and the preset number of air showers, and stores them in a mapping manner. When the personnel enter the sealed passage of the second space, and when the personnel pass through the fixed guide area and reach the variable guide area, a fixed air shower is performed in the fixed guide area, and the fixed air shower corresponds to a fixed number of air showers. The central processing unit uses the monitoring and calibration device to calibrate the personnel with the tag. The central processing unit subtracts the preset number of air showers from the fixed number of air showers to obtain the remaining number of air showers. The central processing unit determines the remaining number of air showers. If the remaining number of air showers is 0, the central processing unit controls the indicator component adjacent to the person to emit a first color light, and the person moves along a first route. If the remaining number of air showers is not 0, the central processing unit controls the indicator component adjacent to the person to emit a second color light, and the person moves along a second route. After each person passes an indicator component, the central processing unit decrements the remaining number of air showers by 1 to obtain the final remaining number of air showers. The central processing unit then determines the final remaining number of air showers. If the final remaining number of air showers is 0, the central processing unit controls the adjacent indicator component to emit a first color light, and the person proceeds along a first route. If the final remaining number of air showers is not 0, the central processing unit controls the adjacent indicator component to emit a second color light, and the person proceeds along a second route. The central processing unit controls the monitoring and calibration device to perform visual image tracking of the personnel and uploads the acquired images to the central processing unit until the personnel leave the second space.
