Description

Technical Field

[0001] This application relates to the field of sampling equipment technology, and in particular to a semi-enclosed sampling device. Background Technology

[0002] In the semiconductor manufacturing industry, electronic chemicals are widely used in processes such as cleaning, etching, photolithography, and electroplating during wafer fabrication and packaging. Electronic chemicals require extremely high purity, with key technical indicators including the number of individual metal ions, individual anions, and particle count. Depending on the specific product characteristics and grade, additional technical indicators may be required. In the production process of electronic chemicals, to monitor the quality of semi-finished products and finished products at different purification stages, sampling locations need to be set up at multiple equipment or process steps. These locations are often scattered, resulting in low current chemical sampling efficiency. Utility Model Content

[0003] In view of this, the purpose of this application is to propose a semi-enclosed sampling device with high sampling efficiency.

[0006] Multiple sampling pipes are installed at the top or back of the semi-enclosed box, with some of the sampling pipes located inside the semi-enclosed box and some of the sampling pipes located outside the semi-enclosed box;

[0007] Multiple valves are arranged in a row inside the semi-enclosed box, and each valve is connected to a sampling pipe.

[0008] The first mounting component is installed inside the semi-enclosed box and is used to fix the valve.

[0009] Optionally, the semi-enclosed enclosure includes a top plate, which is provided with a plurality of first pipe joints, and each first pipe joint is provided with a seal.

[0010] Optionally, the sampling pipe is integrally formed;

[0011] Alternatively, the sampling pipeline may include a first part located outside the semi-enclosed housing and a second part located inside the semi-enclosed housing, with the first part and the second part connected by the first pipeline joint.

[0012] Optionally, the top plate is also provided with an exhaust vent, and the semi-enclosed sampling device further includes:

[0013] An exhaust duct is installed at the top of the semi-enclosed box and connected to the exhaust port.

[0014] Optionally, the semi-enclosed enclosure is provided with a second pipe joint, and the semi-enclosed sampling device further includes:

[0015] The cleaning pipe is housed within the semi-enclosed box and connected to the second pipe joint.

[0016] A water gun is installed at the free end of the cleaning pipe.

[0018] The second mounting component is installed inside the semi-enclosed box and is used to fix the water gun.

[0019] Optionally, the bottom of the semi-enclosed box is provided with a perforated plate and a drain trough, the drain trough being located below the perforated plate, and the bottom of the drain trough having an inclined surface.

[0020] Optionally, the lowest point of the drainage tank is provided with a drainage outlet, and the semi-enclosed sampling device further includes:

[0021] A drain pipe, connected to the drain port, is used to discharge waste liquid from the semi-enclosed tank.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

[0034] Electronic chemicals are key basic materials supporting high-end manufacturing fields such as semiconductors, display panels, and photovoltaics. They encompass various chemical materials used in core processes such as cleaning, etching, deposition, doping, and development throughout the entire electronic device production process. Electronic chemicals have very high purity requirements and strict limits on metal ions and impurities.

[0035] The inventors discovered that purification in current electronic chemical production processes often requires multiple steps and combinations of various purification methods, resulting in multiple sampling points. If sampling points are located near the equipment, sampling personnel must climb to the vicinity of each point, leading to lengthy sampling times and low efficiency.

[0036] The purification process for electronic chemicals is complex, typically requiring multiple steps, such as a combination of filtration, distillation, and ion exchange. Each purification step may be performed in different equipment, and sampling points may need to be set up before and after each piece of equipment to collect samples for analysis and to determine whether the purification device is operating normally and whether maintenance is required. These sampling points are thus dispersed throughout different areas of the production workshop, depending on the distribution of the equipment.

[0037] Moreover, these sampling points are often scattered; some may be on high equipment, others may be in corners of different production lines, or even distributed across different operating platforms. This forces sampling personnel to move back and forth between various dispersed sampling points, and may even have to climb to operate near high sampling points.

[0038] This means that a significant amount of time is spent on preparations such as travel and climbing during each sampling, reducing sampling efficiency and increasing the workload and safety risks for sampling personnel.

[0039] Based on this, this application provides a semi-enclosed sampling device 100 to solve or at least partially solve the above-mentioned problems.

[0040] like Figure 1 and Figure 2 As shown in the illustration, this application discloses a semi-enclosed sampling device 100, which includes a semi-enclosed housing 10, multiple sampling pipes 20, multiple valves 30, and a first mounting member 41. The multiple sampling pipes 20 are disposed on the top or back of the semi-enclosed housing 10, with some pipes located inside and some outside the housing 10. The multiple valves 30 are arranged in a row inside the semi-enclosed housing 10, with each valve 30 connected to one sampling pipe 20. The first mounting member 41 is installed inside the semi-enclosed housing 10 to fix the valves 30.

[0041] Here, it can be understood that the chemical to be sampled is transported into the semi-enclosed housing 10 through the sampling pipe 20, and sampling is performed by opening the valve 30. The sampled chemical flows out inside the semi-enclosed housing 10. The valve 30 can be used to control the flow rate of the chemical in its corresponding sampling pipe 20 to prevent chemical splashing when the flow rate is too high. The first mounting component 41 can be used to fix the valve 30, which can prevent the valve 30 from shaking during the sampling process and improve the stability of the sampling operation.

[0042] This embodiment integrates multiple sampling pipes 20 into a semi-enclosed box 10, which concentrates the sampling points and the sampling operation. Multiple sampling points can be sampled simultaneously, eliminating the need to spend time moving back and forth between sampling points, reducing the sampling time of operators, reducing sampling difficulty, and improving sampling efficiency. At the same time, the semi-enclosed sampling environment provides a reduction in the impact of disorderly diffusion of volatile chemicals on the production environment during the sampling process.

[0043] Furthermore, the semi-enclosed sampling device 100 of this application embodiment has a simple structure and is convenient to install and disassemble, which can speed up the assembly efficiency of the semi-enclosed sampling device 100. The semi-enclosed sampling device 100 can be placed in an easily accessible and operable location, reducing the risk of operators climbing the device.

[0044] In some embodiments, the sampling pipe 20 can be made of different materials and sizes as needed to adapt to the sampling requirements of chemicals of different purity levels. For example, the sampling pipe 20 can be made of high-purity PFA (perfluoroalkoxy resin) or stainless steel. PFA has extremely strong resistance to corrosive media such as strong acids, strong alkalis, and organic solvents, which can reduce the impact of chemicals on the sampling pipe 20, ensure the stable use of the sampling pipe 20, and reduce the impact of metal ion precipitation on product purity.

[0045] In some embodiments, the first mounting component 41 is a fixed bracket, one end of which is welded to the back plate of the semi-enclosed housing 10 by C-shaped channel steel. After the valve 30 is fixed in the slot, it is bolted to the C-shaped channel. C-shaped channel steel is a cold-formed steel with a "C" shaped cross-section, formed by hot rolling or cold bending from a steel plate shaped like the letter C. C-shaped channel steel has high strength and rigidity, can withstand large external forces and pressures, and can effectively support and bear the valve 30.

[0046] In some embodiments, valve 30 is connected to sampling pipe 20 via a compression fitting or threaded fitting.

[0047] In some embodiments, valve 30 may be a needle valve or a diaphragm valve.

[0048] In some embodiments, the inner wall of the semi-enclosed enclosure 10 is made of brushed stainless steel (Ra≤0.8μm) or PP (polypropylene) material to prevent chemicals from contacting metal ions. The semi-enclosed enclosure 10 can be constructed using a frame structure welded from brushed stainless steel, resulting in good structural stability.

[0049] Current open-type sampling methods allow airborne particulate matter to contaminate chemicals, affecting the accuracy of test results. For easily decomposable chemicals like hydrogen peroxide, or volatile chemicals like IPA (isopropanol), exposure to the atmosphere from sealed pipes can release irritating odors, polluting the work environment and endangering the health of operators. This embodiment of the application, by conducting the sampling process within a semi-enclosed enclosure 10, reduces the impact of the external environment on chemicals, improves the accuracy of test results, and also reduces the risk of volatile chemicals contaminating the work environment and harming operators.

[0050] In one embodiment, the semi-enclosed enclosure 10 may include a top plate 11, which is provided with a plurality of first pipe joints 51, each of which is provided with a sealing element. Specifically, the top plate 11 is provided with an opening, and the first pipe joints 51 are fixed at both ends with nuts after passing through the opening, and are tightened at the nuts with sealing elements.

[0051] Specifically, the dimensions of the first pipe connector 51 can be designed according to the dimensions of the sampling pipe 20. The structure of the first pipe connector 51 can be designed according to actual needs, for example, it can be set as a straight or grooved connector. The grooved first pipe connector 51 can connect to sampling pipes 20 with different outer diameters or sampling pipes 20 with the same outer diameter at both ends.

[0052] In some embodiments, the seal may be a sealing gasket or sealing tape, etc. In other embodiments, the seal may be other components with sealing functions.

[0053] In one embodiment, the sampling conduit 20 may be integrally formed. Alternatively, the sampling conduit 20 may include a first part located outside the semi-enclosed housing 10 and a second part located inside the semi-enclosed housing 10, with the first part and the second part connected by a first pipe joint 51.

[0054] Specifically, the sampling pipe 20 is passed through the first pipe joint 51 and then locked with nuts at both ends, or the two parts of the sampling pipe 20 are passed through the pipe joints respectively and then locked with nuts.

[0055] In this embodiment, the integrally formed sampling pipe 20 has better structural stability, which can improve the structural stability of the semi-enclosed sampling device 100. The split-type sampling pipe 20, on the other hand, offers better flexibility, facilitating installation and maintenance.

[0056] In one embodiment, the semi-enclosed housing 10 may be equipped with a second pipe connector 52, and the semi-enclosed sampling device 100 may also include a cleaning pipe 61 and a water gun 62. The cleaning pipe 61 is disposed within the semi-enclosed housing 10 and connected to the second pipe connector 52. The water gun 62 is disposed at the free end of the cleaning pipe 61. Here, the inlet end of the cleaning pipe 61 is connected to a cleaning fluid supply device, and the outlet end is connected to the water gun 62. The water gun 62 can quickly clean the interior of the semi-enclosed housing 10, effectively removing residual chemicals, fine particles, and attached contaminants, avoiding cross-contamination between different batches of chemicals, and ensuring that the interior of the semi-enclosed housing 10 is clean before the next sampling.

[0057] In some embodiments, the second pipe connector 52 is disposed at an opening in the top plate 11 to facilitate connection with the cleaning fluid supply device. In other embodiments, the second pipe connector 52 may also be disposed at an opening in the side plate of the semi-enclosed housing 10.

[0058] In some embodiments, the water gun 62 can be connected to the cleaning pipe 61 by thread or flare, which provides high connection stability and facilitates installation and disassembly.

[0059] In some embodiments, the water gun 62 is made of high-purity PFA material. The water gun 62 has a self-sealing function; a simple press is all it takes to rinse away splashed chemicals. PFA has extremely strong resistance to corrosive media such as strong acids, strong alkalis, and organic solvents, which can reduce the impact of chemicals on the water gun 62 and ensure stable use of the water gun 62 within the semi-enclosed enclosure 10.

[0060] In some embodiments, the cleaning pipeline is a freely extendable spring hose, which can increase the cleaning range of the water gun 62 and improve the cleaning efficiency and effect of the water gun 62. One end of the spring hose is connected to the cleaning connector through a flared threaded connector.

[0061] In some embodiments, the second pipe fitting 52 can be made of PVDF (polyvinylidene fluoride) rods. PVDF has extremely strong chemical corrosion resistance and is stable against various corrosive media such as acids, alkalis, and organic solvents. It can achieve a reliable connection between the cleaning fluid supply device and the cleaning pipe 61, thereby improving the practicality of the semi-closed sampling device 100.

[0062] In one embodiment, the semi-enclosed sampling device 100 may further include a second mounting member 42, which is installed inside the semi-enclosed housing 10 for fixing the water gun 62. Specifically, the second mounting member 42 is installed on the side plate of the semi-enclosed housing 10. When the water gun 62 is not in use, it can be hung on the second mounting member 42 to reduce the impact of chemicals on the water gun 62. When the water gun 62 needs to be used, it can be removed from the second mounting member 42 for convenient use.

[0063] In some embodiments, the second mounting member 42 may be a hook made of bent sheet metal, which is welded to the side plate and located near the water gun 62.

[0064] In existing technologies, each dispersed sampling point requires a separate discharge point, which increases the overall design complexity and significantly increases the workload of subsequent maintenance. For example, the maintenance and cleaning of pipelines at each discharge point need to be handled separately.

[0065] In one embodiment, the bottom of the semi-enclosed housing 10 may be provided with a perforated plate 12 and a drain trough 13. The drain trough 13 is located below the perforated plate 12, and its bottom has an inclined surface. Here, after the chemicals splash out, they can flow downwards into the drain trough 13 through the openings on the perforated plate 12. During sampling, the sampling bottle can be placed on the perforated plate 12 to receive the chemicals to be sampled, or it can be temporarily stored. The bottom surface of the drain trough 13 is an inclined surface, which allows the splashed chemicals to collect downwards along the inclined surface, thereby achieving centralized and sealed discharge of waste liquid without the need for multiple drain pipes, simplifying maintenance.

[0066] In one embodiment, a drain outlet may be provided at the lowest point of the drain tank 13. The semi-enclosed sampling device 100 also includes a drain pipe 71, which is connected to the drain outlet and used to discharge waste liquid from the semi-enclosed housing 10. Specifically, one end of the drain pipe 71 is connected to the drain outlet, and the other end is connected to the waste liquid discharge system. The drain pipe 71 is made of stainless steel and welded to the lowest point at the bottom of the semi-enclosed housing 10.

[0067] In this embodiment, the drain pipe 71 is connected to the drain outlet at the lowest point of the drain tank 13, which can centrally discharge waste liquid, improve the efficiency of waste liquid discharge, and has a simple structure that is easy to maintain.

[0068] In one embodiment, the top plate 11 may also be provided with an exhaust vent, and the semi-enclosed sampling device 100 may also include an exhaust duct 72, which is located at the top of the semi-enclosed housing 10 and connected to the exhaust vent. Here, volatile chemicals will move upward to the exhaust vent and then be discharged from the exhaust duct 72, allowing the exhaust gas to be discharged in a concentrated manner. The sampling environment will not produce irritating odors, and the structure is simple and easy to maintain.

[0069] In some embodiments, one end of the exhaust duct 72 is connected to the exhaust port, and the other end is connected to the exhaust gas discharge duct.

[0070] In some embodiments, the exhaust vent is welded to the upper end of the semi-enclosed housing 10 by a stainless steel pipe.

[0071] In some embodiments, waste gas and waste liquid are centrally discharged within a semi-enclosed enclosure 10, which simplifies piping design and reduces subsequent maintenance workload. The exhaust vent is welded to the top plate 11 of the semi-enclosed enclosure 10, and the drain outlet is welded to the bottom plate. Simultaneously, the semi-enclosed structure and the large ventilation opening at the top limit the disorderly diffusion of volatile gases during sampling, improving the safety of the production environment. Waste liquid discharged from the sampling pipe 20 during sampling can be centrally discharged through the drain tank 13 and drain pipe 71 connected to the device's waste liquid discharge pipe.

[0072] In one embodiment, the semi-enclosed enclosure 10 may further include an opening and closing door panel 80 located on the front side of the semi-enclosed enclosure 10. Specifically, see... Figure 2 The opening and closing door panel 80 may include a left door panel and a right door panel, and the opening and closing door panel 80 is equipped with a door handle for easy gripping and use. During the sampling process, when it is necessary to use the valve 30 to adjust the flow rate or velocity of the chemicals in the sampling pipeline 20, the door panel can be opened to operate the valve 30.

[0073] In some embodiments, the hinged door panel 80 is disposed on the door frame of the semi-enclosed box 10, and the hinged door panel 80 is fixed to the door frame by hinges and bolts.

[0074] In some embodiments, the door panel may be made of a transparent material to facilitate observation of the sampling process inside the semi-enclosed enclosure 10.

[0075] In some embodiments, the hinged door panel 80 may be made of PVC (polyvinyl chloride), which has good chemical stability and can withstand most acids, alkalis and common solvents. The PVC hinged door panel 80 is tough and lightweight, providing both impact resistance to prevent damage to the semi-enclosed sampling device 100 during handling and reducing the overall weight of the semi-enclosed sampling device 100.

[0076] In one embodiment, the semi-enclosed sampling device 100 may further include a support leg 90, which is disposed at the bottom of the semi-enclosed housing 10 to support the semi-enclosed housing 10. Specifically, the support leg 90 can ensure the stable placement of the semi-enclosed housing 10, guarantee the smooth progress of the sampling process, and reduce the risk of chemical leakage.

[0077] In addition, the support leg 90 can raise the semi-enclosed box 10, so that a certain gap is formed between the bottom of the semi-enclosed box 10 and the placement surface, which can facilitate cleaning of the area under the semi-enclosed box 10, prevent pollutants from accumulating at the bottom of the semi-enclosed box 10, reduce the corrosion of the bottom of the semi-enclosed box 10 by ground moisture or accidental liquid spills, and extend the service life of the semi-enclosed sampling device 100.

[0078] In some embodiments, the support leg 90 is welded to the bottom plate of the semi-enclosed box 10, and the support leg 90 may be made of stainless steel square steel.

[0079] In some embodiments, the workflow of the semi-enclosed sampling device 100 is illustrated as follows: After connecting each sampling point branch pipe to the sampling pipeline 20, they are numbered to confirm the location of the sampling points. During sampling, the operator simply stands in front of the semi-enclosed sampling device 100, opens the opening and closing door 80, opens the corresponding valve 30 of the sampling point to be sampled, drains the medium originally stored in the sampling pipeline 20, and the waste liquid is directly discharged into the drain tank 13 at the lower end of the semi-enclosed sampling device 100, and collects at the drain port along the inclined surface, and then discharged into the waste liquid main pipe. After replacing the material, the valve 30 is closed, the sampling bottle is aligned with the outlet end of the sampling pipeline 20, and the valve 30 is opened to receive the sampled material. The decomposition or volatilization waste gas generated during the sampling process is extracted by the exhaust pipe 72 at the top of the semi-enclosed housing 10.
