Description

Technical Field

[0001] This utility model relates to an electronic-grade isopropanol particulate matter detection and sampling device. Background Technology

[0002] Electronic-grade isopropanol, as a high-purity organic solvent, plays a crucial role in the electronics and information industry. In semiconductor manufacturing, it is commonly used in critical processes such as chip cleaning and photoresist removal. It effectively removes stains and residues from chip surfaces, ensuring high performance and reliability. The quality of electronic-grade isopropanol directly impacts the production of electronic components. Particulate matter content is one of the key indicators of its quality. Effective particulate matter detection allows for the timely identification of impurities in electronic-grade isopropanol, enabling appropriate purification measures to ensure compliance with stringent quality standards.

[0003] Currently, the electronic grade isopropanol particulate matter detection process requires sampling of the electronic grade isopropanol. However, existing sampling devices lack a dedicated sampling platform. During sampling, the sampling bottle is placed directly on the workbench. Due to negligence or limited operating space, staff may accidentally knock over the sampling bottle, causing the sample to spill, become contaminated, or even be lost. This not only affects the smooth progress of the detection work but may also lead to the need for resampling, wasting time and effort. Utility Model Content

[0004] The main objective of this invention is to provide an electronic-grade isopropanol particulate matter detection and sampling device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] An electronic-grade isopropanol particulate matter detection and sampling device includes a sampler, a sampling platform is provided on one bottom surface of the sampler, a sampling bottle protection seat is provided on the sampling platform, and fixed baffles are provided on the left, right and rear sides of the sampling bottle protection seat. Insertion grooves are provided on the inner walls of the front side and the left and right side fixed baffles of the sampling bottle protection seat, and insertion baffles are provided in the insertion grooves.

[0007] Preferably, a support plate is provided on the sampling platform behind the sampling bottle protection seat. A lead screw is provided at the center of the support plate. The upper and lower sides of the lead screw are rotatably connected to the support plate and the sampling platform, respectively. The top end of the lead screw passes through the support plate and is fixed with a worm gear. A worm is meshed on the worm gear. A movable block that is threadedly connected to the lead screw is provided on the outer wall of the fixed baffle at the rear.

[0008] Preferably, guide posts are provided on both sides of the lead screw, and guide holes are provided on both sides of the moving block.

[0009] Preferably, one end of the worm gear is provided with a rotating handle.

[0010] Preferably, the sampling platform has vertically arranged slide rails on both sides of the sampling bottle protection seat, and sliders are arranged on the outer walls of the fixed baffles on the left and right sides.

[0011] Preferably, the sampling platform is provided with a groove, the sampling bottle protection seat is disposed in the groove, and the top surface of the sampling bottle protection seat is on the same plane as the top surface of the sampling platform.

[0012] Preferably, the sampling bottle protective base is provided with an anti-slip pad.

[0013] Preferably, a handle is provided on the front side of the plug-in baffle.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] 1. This utility model, by setting fixed baffles on the left, right, and rear sides of the sampling bottle protection holder, and a plug-in baffle on the front side, can effectively shield and protect the electronic-grade isopropanol sampling bottle placed inside the sampling bottle protection holder from multiple directions. During the sampling process for electronic-grade isopropanol particulate matter detection, this design can prevent the sampling bottle from tipping over or breaking due to staff negligence, ensuring the sampling bottle is in a safe state and thus guaranteeing the smooth progress of the electronic-grade isopropanol particulate matter detection sampling work.

[0016] 2. This utility model, through the pluggable design of the pluggable baffle, allows the pluggable baffle to be removed when it is necessary to place the sampling bottle. After the sampling bottle is placed in, the pluggable baffle is inserted, which can not only provide protection, but also not affect the normal handling of the sampling bottle.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-5 As shown, the electronic grade isopropanol particulate matter detection and sampling device provided in this embodiment includes a sampler 1, a sampling platform 2 is provided on one bottom surface of the sampler 1, a sampling bottle protection seat 3 is provided on the sampling platform 2, and fixed baffles 4 are provided on the left, right and rear sides of the sampling bottle protection seat 3. Insertion grooves 5 are provided on the inner walls of the fixed baffles 4 on the front side and the left and right sides of the sampling bottle protection seat 3, and insertion baffles 6 are provided in the insertion grooves 5.

[0025] The sampling bottle protective base 3 and the fixed baffle 4 are fixedly connected.

[0026] When it is time to place the sampling bottle, remove the connector baffle 6 to leave the front of the sampling bottle protection base 3 unobstructed, so that the sampling bottle can be easily placed on the sampling bottle protection base 3. After placement, remove the connector baffle 6 to provide full protection for the sampling bottle and prevent it from being accidentally knocked over by staff.

[0027] When performing particulate matter detection of electronic-grade isopropanol, the laboratory environment is typically stable and free from violent shaking. Therefore, the likelihood of the sampling bottle tipping over due to external vibrations is low, eliminating the need for overly complex professional clamping and securing devices. By installing baffles around the sampling bottle, it is possible to effectively prevent it from tipping over due to operator negligence. This ensures both the stability of the sampling bottle and ease of operation, meeting the practical needs of electronic-grade isopropanol particulate matter detection.

[0028] In this embodiment, as Figure 5As shown, a support plate 7 is provided on the sampling platform 2 at the rear side of the sampling bottle protection seat 3. A lead screw 8 is provided at the center of the support plate 7. The upper and lower sides of the lead screw 8 are rotatably connected to the support plate 7 and the sampling platform 2, respectively. The top of the lead screw 8 passes through the support plate 7 and is fixed with a worm gear 9. A worm 10 is meshed on the worm gear 9. A movable block 11 is provided on the outer wall of the rear fixed baffle 4 and is threadedly connected to the lead screw 8. The worm gear 9 is driven by the worm 10, which drives the lead screw 8 to rotate. The movable block 11 moves linearly along the lead screw 8, so that the sampling bottle can move up and down with the sampling bottle protection seat 3, avoiding the problem that the sampling tube on the sampler 1 cannot contact the electronic grade isopropanol because the sampling bottle is too short.

[0029] In this embodiment, as Figure 5 As shown, guide posts 12 are provided on both sides of the lead screw 8, and guide holes 13 are provided on both sides of the moving block 11 to prevent the moving block 11 from shaking or shifting when the lead screw 8 rotates, thus ensuring the accuracy and stability of height adjustment.

[0030] In this embodiment, as Figure 1 As shown, a rotating handle 14 is provided at one end of the worm gear 10, providing an easy gripping point for the operator and facilitating the application of torque to drive the worm gear 10.

[0031] In this embodiment, as Figure 1 As shown, the sampling platform 2 has vertical slide rails 15 on both sides of the sampling bottle protection seat 3, and sliders 16 are provided on the outer walls of the left and right fixed baffles 4 to further ensure the stability of the sampling bottle protection seat 3 when it moves.

[0032] In this embodiment, as Figure 3 As shown, a groove 17 is provided on the sampling platform 2, and a sampling bottle protection seat 3 is placed in the groove 17. The top surface of the sampling bottle protection seat 3 is on the same plane as the top surface of the sampling platform 2. The groove 17 is designed to hide the edge of the sampling bottle protection seat 3, reduce the protruding structure on the sampling platform 2, and avoid bumps when placing electronic grade isopropanol sampling bottles.

[0033] In this embodiment, as Figure 4 As shown, the sampling bottle protective base 3 is provided with an anti-slip pad 18. The anti-slip pad 18 increases the friction to further prevent the electronic grade isopropanol sampling bottle from sliding or tipping over.

[0034] In this embodiment, as Figure 1 As shown, a handle 19 is provided on the front side of the plug-in baffle 6. The handle 19 provides an easy gripping point for the operator, making it convenient to quickly plug and unplug the plug-in baffle 6.

[0035] In summary, this embodiment provides effective shielding and protection for electronic-grade isopropanol sampling bottles placed within the sampling bottle protection base 3 from multiple directions by setting fixed baffles 4 on the left, right, and rear sides of the sampling bottle protection base 3, and a plug-in baffle 6 on the front side. During the sampling process for electronic-grade isopropanol particulate matter detection, this design prevents the sampling bottles from tipping over or breaking due to staff negligence, ensuring the bottles remain safe and guaranteeing the smooth progress of the electronic-grade isopropanol particulate matter detection sampling work. The pluggable design of the pluggable baffle 6 allows for easy removal of the sampling bottle when it needs to be placed; after placing the bottle, the baffle 6 is inserted, providing protection without affecting the normal handling of the sampling bottle.

[0036] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
