Description

Technical Field

[0001] The present invention relates to the technical field of wet electronic chemicals, and more specifically to a device for separating and purifying wet electronic chemicals. Background Art

[0002] Electronic wet chemicals are widely used in the manufacture of very large-scale integrated circuits, mainly for wafer surface cleaning, cleaning and etching during chip processing. In addition, electronic wet chemicals are used for glass substrate cleaning, silicon nitride, silicon dioxide etching agents, etc. in the LCD industry; and for silicon wafer surface cleaning and etching agents in photovoltaic and LED manufacturing. The purity and cleanliness of electronic wet chemicals have a very important impact on the yield, electrical performance and reliability of integrated circuits.

[0003] According to the patent document: CN105606591A, an analysis method for B impurity elements in electronic wet chemicals is disclosed, and an inductively coupled plasma atomic emission spectrometer is used for analysis, which is characterized in that after starting up the machine, the sampling system of the inductively coupled plasma atomic emission spectrometer is cleaned with high-purity inorganic acid for 48 to 72 hours before sampling, and then rinsed with ultrapure water for 6 to 18 hours without shutting down in between. This method can eliminate the interference of B element in the detection background, and has accurate measurement, high measurement precision, low detection limit, fast determination, and wide linear range.

[0004] Generally, the separation and purification of wet electronic chemicals firstly involves sample pretreatment and solid-liquid separation, and then preliminary separation is performed by salting-out method. However, when performing preliminary separation by salting-out method, sodium sulfate is poured into the separation and purification tank to be blended with the wet electronic chemicals to perform preliminary passivation of the wet electronic chemicals. The sodium sulfate easily sinks to the bottom of the separation and purification tank and cannot be well blended with the wet electronic chemicals. This may result in insufficient fusion of sodium sulfate and the wet electronic chemicals, thereby affecting the effect of preliminary passivation. Afterwards, the wet electronic chemicals are separated by column chromatography according to different reactions and then input into test tubes for separation, so as to perform the next step of processing or storage. When the wet electronic chemicals need to be separated according to different reactions, the staff also needs to constantly change test tubes, which is troublesome. After the above steps are completed, if the next process is not required, the test tubes need to be transported to a sterile or dry place for storage. However, many test tubes need to be transported at one time, which consumes the energy or time of the staff, and the instruments need to be prepared again, which increases the cost.

Afterwards, the wet electronic chemicals are input into a test tube for separation according to different reactions by using column chromatography, so as to perform the next step of processing or storage. When the wet electronic chemicals need to be separated according to different reactions, the staff also needs to constantly replace the test tubes, which is more troublesome.

The top of the glass column tank 314 is aligned with the bottom of the conveying head 353. The test tube turntable 4 includes a base 41. The left side of the base 41 is fixedly connected with a third motor placement block 42. The inner wall of the third motor placement block 42 is fixedly connected with a third motor 43. The output end of the third motor 43 extends to the inner wall of the base 41 and is fixedly connected with a rotating rod 44.

The outer wall of the rotating disk 48 is fixedly connected with a plurality of glass test tube placement racks 49 in a circular array. The inner walls of the plurality of glass test tube placement racks 49 are all movably connected with glass test tubes 410. The top of the purification tank 329 is hollowed out. Wet electronic chemicals and sodium sulfate are poured into the purification tank 329 in proportion, and then the stirring rod motor 3310 is started. The stirring rod motor 3310 starts to work. Through the transmission of the main gear connecting shaft 3311 and the sub-gear connecting shaft 3313, the sub-gear 3316 and the main gear 3312 are meshed and rotated with each other. This transmission method allows the two stirring rod top rods 3315 and the bow-shaped stirring rod 3317 at the bottom to rotate and stir inside the purification tank 329, ensuring that the wet electronic chemicals and sodium sulfate can be fully mixed and reacted. At the same time, through the drive of the second motor 333, the meshing of the conical teeth 334 and the second conical teeth 335 causes the bidirectional screw rod 336 to start rotating, which causes the two transmission blocks 337 to move on the bidirectional screw rod 336, thereby adjusting the positions of the two rotating rods 338 and the stirring rod motor placement block 339, so that the position and stirring angle of the bow-shaped stirring rod 3317 in the purification tank 329 can be adjusted as needed to obtain the best stirring effect.

When the impurities on the filter 343 accumulate to a certain extent, the filter housing 342 can be taken out from the filter chamber body 341 by pulling the handle 344 for cleaning or replacement; The filtered electronic chemicals are transported to the storage bin 35 for temporary storage. When they are needed, they are transported to the glass column tank 314 through the transport pipe 352 and the transport head 353.

Finally, the pure electronic chemicals are transported to the test tube turntable 4, and the third motor 43 drives the rotating rod 44 and the worm gear 45 to rotate, and meshes with the second gear 46 to drive, so that the second rotating rod 47 and the turntable 48 rotate, and the glass test tube placement rack 49 on the turntable 48 and the glass test tube 410 inside thereof rotate accordingly, so that the operator can classify the wet electronic chemicals flowing downward from the test tube glass column tank 314 into different glass test tubes 410; The design and operation process of the entire equipment is aimed at purifying, filtering, storing and sampling wet electronic chemicals to ensure that the final electronic chemicals meet the quality requirements and meet production needs.

[0023] like Fig. 9As shown, the transmission base 1 includes a transmission base body 11, a slide groove 12 is opened on the top of the transmission base body 11, a partition 14 is fixedly connected to the left side of the inner wall of the slide groove 12 opened on the top of the transmission base body 11, a screw motor 13 is fixedly connected to the left side of the partition 14, the output end of the screw motor 13 passes through the right side of the partition 14 and is fixedly connected to a screw rod 15, the right end of the screw rod 15 is movably connected to the right side of the inner wall of the slide groove 12, the outer wall of the screw rod 15 is threadedly connected to a turntable transmission block 16, the top of the turntable transmission block 16 is fixedly connected to the bottom of the base 41, and the storage bin 2 includes a storage bin shell 21, and the front inner wall of the storage bin shell 21 is fixedly connected A tempered glass 22 is connected, a desiccant placement groove 28 is fixedly connected to the rear side of the inner wall of the storage bin shell 21, a sealed door motor placement block 23 is fixedly connected to the top of the tempered glass 22, a sealed door motor 24 is fixedly connected to the inner wall of the sealed door motor placement block 23, a sealed door screw rod 25 is fixedly connected to the output end of the sealed door motor 24, a sealed door transmission block 26 is threadedly connected to the outer wall of the sealed door screw rod 25, a sealed door 27 is fixedly connected to the right side of the sealed door transmission block 26, the bottom of the sealed door 27 extends to the inner wall of the storage bin shell 21 through the top of the storage bin shell 21, and the outer wall of the sealed door 27 is slidably connected to the top inner wall of the storage bin shell 21; When the separation and purification of wet electronic chemicals is completed, the screw motor 13 is first started, and the screw motor 13 starts to work, driving the screw 15 to rotate in the slide groove 12. Since the turntable transmission block 16 is threadedly connected to the outer wall of the screw 15, the turntable transmission block 16 will move along the screw 15, thereby driving the base 41 and the equipment components thereon to slide on the conveying base body 11. This step is to adjust the relative position between the base 41 and the storage bin 2 so as to smoothly transport the purified wet electronic chemicals to the storage bin 2. As the turntable transmission block 16 moves, the base 41 gradually approaches the storage bin housing 21. When the positions of the two are adjusted appropriately, the screw motor 13 is turned off to stop the movement of the base 41. At this time, the base 41 enters the interior of the storage bin housing 21. Next, the sealing door motor 24 is started to rotate the sealing door screw 25. Since the sealing door transmission block 26 is threadedly connected to the outer wall of the sealing door screw 25, the sealing door transmission block 26 will move along the sealing door screw 25, thereby driving the sealing door 27 to slide on the top of the storage bin housing 21. This step is to adjust the position of the sealing door 27 so that it can be tightly closed after the wet electronic chemicals completely flow into the storage bin housing 21 to prevent the wet electronic chemicals from volatilizing or being contaminated by the outside. During the whole process, the tempered glass 22 allows the operator to clearly observe the situation inside the storage bin housing 21, which helps the operator to find problems in time and make adjustments to ensure the smooth progress of the purification and storage process; Through the above steps, wet electronic chemicals complete a series of operations such as purification, filtration, storage and sampling in the equipment, and finally obtain electronic chemicals that meet the quality requirements. The design and operation process of the entire equipment embodies the concepts of efficiency, convenience and environmental protection, and provides strong support for the production of electronic chemicals.

[0024] Working principle of the present invention: The top of the purification tank 329 is hollowed out, wet electronic chemicals and sodium sulfate are poured into the purification tank 329 in proportion, and then the stirring rod motor 3310 is started, and the stirring rod motor 3310 starts to work, and the transmission of the main gear connecting shaft 3311 and the sub-gear connecting shaft 3313 makes the sub-gear 3316 and the main gear 3312 mesh with each other and rotate. This transmission mode makes the two stirring rod top rods 3315 and the bow-shaped stirring rod 3317 at the bottom rotate inside the purification tank 329. Rotate and stir to ensure that the wet electronic chemicals and sodium sulfate can be fully mixed and reacted. At the same time, through the drive of the second motor 333, the conical teeth 334 are engaged with the second conical teeth 335, so that the bidirectional screw rod 336 starts to rotate, which causes the two transmission blocks 337 to move on the bidirectional screw rod 336, thereby adjusting the positions of the two rotating rods 338 and the stirring rod motor placement block 339, so that the position and stirring angle of the bow stirring rod 3317 in the purification tank 329 can be adjusted as needed to obtain the best stirring effect; After a period of stirring and reaction, the impurities and gases in the mixture are effectively removed, and relatively pure electronic chemicals are obtained. At this time, the stirring rod motor 3310 and the second motor 333 can be turned off, and then the transmission baffle 326 of the motor 324 is started to move to one side to leak out the bottom of the purification tank 329, so that the purified wet electronic chemicals pass through the bottom of the purification tank 329 into the filter chamber 34, and the filter housing 342 and the filter 343 inside it further filter the purified electronic chemicals to remove the remaining tiny impurities therein. When the impurities on the filter 343 accumulate to a certain extent, the filter housing 342 can be taken out from the filter chamber body 341 by pulling the handle 344 for cleaning or replacement; The filtered electronic chemicals are transported to the storage bin 35 for temporary storage. When they are needed, they are transported to the glass column tank 314 through the transport pipe 352 and the transport head 353. The interior of the glass column tank 314 is filled with alumina, and then the electronic chemicals flow downward through the glass column tank 314 for separation. Finally, the pure electronic chemicals are transported to the test tube turntable 4, and the third motor 43 drives the rotating rod 44 and the worm gear 45 to rotate, and meshes with the second gear 46 to drive, so that the second rotating rod 47 and the turntable 48 rotate, and the glass test tube placement rack 49 on the turntable 48 and the glass test tube 410 inside thereof rotate accordingly, so that the operator can classify the wet electronic chemicals flowing downward from the test tube glass column tank 314 into different glass test tubes 410; The design and operation of the entire equipment is aimed at achieving the purification, filtration, storage and sampling of wet electronic chemicals to ensure that the final electronic chemicals meet the quality requirements and meet production needs; When the separation and purification of wet electronic chemicals is completed, the screw motor 13 is first started, and the screw motor 13 starts to work, driving the screw 15 to rotate in the slide groove 12. Since the turntable transmission block 16 is threadedly connected to the outer wall of the screw 15, the turntable transmission block 16 will move along the screw 15, thereby driving the base 41 and the equipment components thereon to slide on the conveying base body 11. This step is to adjust the relative position between the base 41 and the storage bin 2 so as to smoothly transport the purified wet electronic chemicals to the storage bin 2. As the turntable transmission block 16 moves, the base 41 gradually approaches the storage bin housing 21. When the positions of the two are adjusted appropriately, the screw motor 13 is turned off to stop the movement of the base 41. At this time, the base 41 enters the interior of the storage bin housing 21. Next, the sealing door motor 24 is started to rotate the sealing door screw 25. Since the sealing door transmission block 26 is threadedly connected to the outer wall of the sealing door screw 25, the sealing door transmission block 26 will move along the sealing door screw 25, thereby driving the sealing door 27 to slide on the top of the storage bin housing 21. This step is to adjust the position of the sealing door 27 so that it can be tightly closed after the wet electronic chemicals completely flow into the storage bin housing 21 to prevent the wet electronic chemicals from volatilizing or being contaminated by the outside. During the whole process, the tempered glass 22 allows the operator to clearly observe the situation inside the storage bin housing 21, which helps the operator to find problems in time and make adjustments to ensure the smooth progress of the purification and storage process; Through the above steps, wet electronic chemicals complete a series of operations such as purification, filtration, storage and sampling in the equipment, and finally obtain electronic chemicals that meet the quality requirements. The design and operation process of the entire equipment embodies the concepts of efficiency, convenience and environmental protection, and provides strong support for the production of electronic chemicals.
