Description

Technical Field

[0001] The invention relates to the field of chemical preparation devices, in particular to an electronic-grade chemical repolarization tank. Background Art

[0002] TMAH (tetramethylammonium hydroxide) is a commonly used developer component in the semiconductor manufacturing process. It plays an important role in the development of photoresists. The repolarization cell is a device for electrochemical synthesis of TMAH. The repolarization cell is an electrolytic cell. In order to increase voltage, stabilize current, disperse heat and improve efficiency, the repolarization cell is usually equipped with multiple unit cells connected in series. The repolarization cell mainly converts methylamine and water into TMAH through electrolytic reaction.

[0003] In order to prevent TMAH from volatilizing during the electrolysis process, prevent impurities from contaminating TMAH and maintain the composition of the electrolyte, the existing bipolar cell for preparing TMAH usually adopts a sealed structure. Preparing TMAH in a sealed state can improve production efficiency, increase product purity and ensure production safety.

[0004] However, in order to ensure good sealing when electrolyzing TMAH in the existing sealed bipolar cell, it is inconvenient to add the raw materials required for preparing TMAH, which makes the loading steps more complicated and reduces the production efficiency. In addition, since the raw materials for electrolyzing TMAH in a sealed state are in a static state, the raw materials are prone to precipitation during the electrolysis process, thereby reducing the preparation effect of TMAH.

[0005] In summary, there is an urgent need for a preparation device that can quickly add raw materials for preparing TMAH, improve reaction efficiency, and prevent raw material precipitation. Summary of the invention

[0032] Refer to Figure 1 , Figure 2 and Figure 5 , an electronic-grade chemical bipolar groove, comprising a C-shaped frame 1, a bipolar electrolytic cell 2 is fixedly installed on the upper part of the lower horizontal section of the C-shaped frame 1, a sealing cover 3 is slidably arranged up and down on the lower part of the upper horizontal section of the C-shaped frame 1, the lower part of the sealing cover 3 is slidably sleeved on the outside of the bipolar electrolytic cell 2, a partition board 4 is fixedly installed in the middle of the sealing cover 3, an opening and closing mechanism 5 for controlling feeding and discharging is jointly arranged on the sealing cover 3 and the partition board 4, and an accelerating mechanism 6 for accelerating the reaction rate is arranged on the sealing cover 3.

[0033] When preparing tetramethylammonium hydroxide, first, the raw materials are filled into the inner part of the sealing cover 3 through the opening and closing mechanism 5, so that the raw materials are located between the partition plate 4 and the top wall of the sealing cover 3. At the same time, the raw materials are agitated by the accelerating mechanism 6 to prevent the raw materials from precipitating. Subsequently, the opening and closing mechanism 5 moves the sealing cover 3 downward, so that the raw materials inside the sealing cover 3 are injected into the bipolar electrolytic cell 2, so that the bipolar electrolytic cell 2 electrolyzes the raw materials. At the same time, the opening and closing mechanism 5 drives the sealing cover 3 to store the raw materials again, and the accelerating mechanism 6 stirs the raw materials in the bipolar electrolytic cell 2 to prevent the raw materials from precipitating.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the opening and closing mechanism 5 includes a feeding pipe 51 fixedly installed on the upper side of the sealing cover 3. The lower part of the feeding pipe 51 is of a conical structure. A first sealing plug 52 is slidably arranged up and down inside the feeding pipe 51. A limiting component 55 for fixing its position is arranged on the first sealing plug 52. The upper part of the horizontal section on the upper side of the C-shaped frame 1 is fixedly installed with a hydraulic cylinder 58, and the telescopic section of the hydraulic cylinder 58 is fixedly connected with the sealing cover 3.

[0035] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the limiting component 55 includes a blocking plate 551 slidably arranged left and right on the upper right side of the first sealing plug 52. A pushing spring is arranged between the first sealing plug 52 and the feeding pipe 51. A return spring is arranged between the right side of the blocking plate 551 and the first sealing plug 52. The upper end of the blocking plate 551 is provided with an inclined surface that gradually slopes upward from left to right. A connecting piece 552 is slidably arranged left and right on the upper left side of the first sealing plug 52. The lower part of the connecting piece 552 is provided with an inclined surface that gradually slopes downward from left to right. A rectangular notch is opened in the upper part of the connecting piece 552. A compression spring is arranged between the lower right side of the connecting piece 552 and the first sealing plug 52.

[0036] Refer to Figure 3 and Figure 4 , a feeding component 56 is fixedly installed inside the upper horizontal section of the C-shaped frame 1. The feeding component 56 includes a feeding pipe 561 fixedly installed inside the upper horizontal section of the C-shaped frame 1. The lower part of the feeding pipe 561 is slidably sleeved outside the feeding pipe 51 up and down. The upper end of the feeding pipe 561 is connected to a storage device for storing reaction raw materials. A pushing column 562 is fixedly installed at the central position of the inner lower part of the feeding pipe 561. An L-shaped block 563 is fixedly installed on the left side of the lower end of the pushing column 562. A pushing inclined block 564 is fixedly installed on the right side of the lower end of the pushing column 562.

[0037] In the initial state, the No. 1 sealing plug 52 is attached to the conical surface of the conical structure at the lower part of the feeding tube 51, so that the No. 1 sealing plug 52 blocks the lower part of the feeding tube 51, thereby closing the feeding tube 51, and the blocking plate 551 is in a state of moving to the left, so that the blocking plate 551 blocks the feeding tube 51, thereby preventing the No. 1 sealing plug 52 from moving downward relative to the feeding tube 51, and then locking the No. 1 sealing plug 52.

[0038] When feeding is required, the telescopic section of the hydraulic cylinder 58 is retracted, so that the hydraulic cylinder 58 drives the sealing cover 3 to move upward, and the sealing cover 3 drives the feeding tube 51 to move upward. The feeding tube 51 drives the No. 1 sealing plug 52 to move upward synchronously through the blocking plate 551, so that the feeding tube 51 is always in a closed state during the upward movement.

[0039] When the upper end of the No. 1 sealing plug 52 abuts against the lower end of the abutting column 562, the L-shaped block 563 is inserted into the interior of the No. 1 sealing plug 52, so that the horizontal section of the L-shaped block 563 corresponds to the rectangular notch position of the connecting piece 552, and at the same time, the pushing block 564 contacts the inclined surface of the upper end of the blocking plate 551, so that the pushing block 564 pushes the blocking plate 551 to the right, so that the blocking plate 551 no longer blocks the feeding tube 51, and then continues to lift the sealing cover 3, so that the abutting column 562 reacts on the No. 1 sealing plug 52 The reaction force pushes it downward relative to the feeding tube 51, thereby opening the feeding tube 51, and then the feeding tube 561 injects the raw material into the interior of the sealing cover 3.

[0040] While the No. 1 sealing plug block 52 moves downward relative to the feeding tube 51, the feeding tube 51 pushes the connecting piece 552 to the right, so that the horizontal section of the L-shaped block 563 is inserted into the notch of the connecting piece 552, thereby fixing the L-shaped block 563 and the connecting piece 552 together.

[0041] See also Figure 2 , Figure 5 , Figure 7 and Figure 8 The opening and closing mechanism 5 also includes a feed pipe 53 fixedly installed at the lower part of the partition plate 4 and corresponding to each cell of the bipolar electrolytic cell 2. A conical surface is provided on the inner side of the upper part of the feed pipe 53. A No. 2 sealing plug 54 is provided inside the feed pipe 53 for sliding up and down. A locking assembly 57 is provided on the partition plate 4 to limit the No. 2 sealing plug 54.

[0042] See also Figure 5 , Figure 7 and Figure 8The locking assembly 57 includes a curved plate 571 which is fixedly mounted on the lower end of the No. 2 sealing plug 54. A coil spring is arranged between the curved plate 571 and the partition plate 4. A movable square rod 572 is fixedly mounted on the left and right ends of the curved plate 571. The movable square rod 572 is slidably connected to the corresponding position of the partition plate 4 up and down. A fixing portion 573 for locking the position of the curved plate 571 is arranged on the movable square rod 572.

[0043] See also Figure 5 , Figure 7 , Figure 8 and Fig. 9 The fixed part 573 includes a locking bevel block 5731 which is slidably arranged inside the movable square rod 572, a rectangular groove is provided at the lower part of the partition plate 4 corresponding to the position of the movable square rod 572, a linear groove 5732 which is gradually inclined downward from front to back is provided at the rear left part of the locking bevel block 5731, an active push rod 5733 is slidably arranged inside the movable square rod 572, an active push spring is provided between the upper end of the active push rod 5733 and the partition plate 4, the upper right part of the active push rod 5733 slides inside the linear groove 5732 through a protruding column, and blocking strips 5734 are fixedly installed on the upper parts of the left and right side walls of the bipolar electrolytic cell 2.

[0044] See also Figure 3 , Figure 5 and Figure 6 The acceleration mechanism 6 includes a follower plate 61 fixedly mounted at the bottom of the No. 1 sealing plug 52 , and a rotating column 62 corresponding to the No. 2 sealing plug 54 is rotatably arranged at the bottom of the follower plate 61 .

[0045] When the sealing cover 3 moves upward, the sealing cover 3 drives the No. 2 sealing plug 54 to move synchronously through the partition plate 4, so that the coil spring pushes the curved plate 571 downward by its own elastic force, and the curved plate 571 drives all the No. 2 sealing plugs 54 to move downward relative to the discharge pipe 53, so that the No. 2 sealing plug 54 fits on the conical surface of the discharge pipe 53, so that the No. 2 sealing plug 54 blocks the discharge pipe 53, preventing the raw materials inside the sealing cover 3 from directly flowing out of the discharge pipe 53.

[0046] When the sealing cover 3 moves upward, the sealing cover 3 drives the curved plate 571 to move upward away from the blocking strip 5734. When the No. 2 sealing plug 54 blocks the discharge pipe 53, the curved plate 571 drives the locking bevel 5731 to move downward to the rectangular groove position at the lower part of the partition plate 4 by moving the square rod 572. At this time, the active push spring pushes the active push rod 5733 downward through its own elastic force. The active push rod 5733 drives the locking bevel 5731 to move forward to the inside of the rectangular groove at the lower part of the partition plate 4 through the raised column thereon and the notch of the straight groove 5732, so that the locking bevel 5731 is blocked on the rectangular groove at the lower part of the partition plate 4 through its upper horizontal section, thereby preventing the curved plate 571 from driving the No. 2 sealing plug 54 to move upward relative to the discharge pipe 53, thereby keeping the discharge pipe 53 in a closed state at all times.

[0047] When the No. 1 sealing plug 52 moves downward, the No. 1 sealing plug 52 drives the follower plate 61 to move downward, and the follower plate 61 drives the rotating column 62 to move downward until it is against the upper side surface of the No. 2 sealing plug 54, so that the No. 2 sealing plug 54 is tightly fitted on the conical surface of the discharge pipe 53 through the downward push of the rotating column 62, further increasing the sealing effect of the No. 2 sealing plug 54 on the discharge pipe 53, preventing the raw materials from leaking directly from the discharge pipe 53.

[0048] See also Figure 1 , Figure 3 , Figure 5 and Figure 6 The acceleration mechanism 6 also includes a paddle 63 fixedly mounted on the outer side of the lower part of the rotating column 62. A driving assembly 66 is arranged on the sealing cover 3. The driving assembly 66 includes an executive motor 661 fixedly mounted on the left side of the upper part of the sealing cover 3. A rotating square rod 662 is rotatably arranged on the lower side of the top wall of the sealing cover 3. The rotating square rod 662 is slidably connected to the leftmost rotating column 62 up and down. The upper end of the rotating square rod 662 is fixedly connected to the output shaft of the executive motor 661. The outer sides of all the rotating columns 62 are connected together by chains.

[0049] When the raw material is added to the sealing cover 3 from the feeding pipe 51, the execution motor 661 is started, so that the execution motor 661 drives the rotating square rod 662 to rotate, and the rotating square rod 662 drives the leftmost rotating column 62 to rotate. The leftmost rotating column 62 drives all the rotating columns 62 to rotate through the chain, so that the rotating column 62 stirs the raw material inside the sealing cover 3 through the paddle 63 thereon to prevent the raw material from settling inside the sealing cover 3.

[0050] When the raw material filling inside the sealing cover 3 is completed, the telescopic section of the hydraulic cylinder 58 is extended to drive the sealing cover 3 to move downward, and the sealing cover 3 drives the feeding pipe 51 to move downward synchronously. Since the L-shaped block 563 is connected to the connecting piece 552, the No. 1 sealing plug block 52 is connected to the abutting column 562, so that when the feeding pipe 51 moves downward, the No. 1 sealing plug block 52 keeps its position unchanged, and then the No. 1 sealing plug block 52 blocks the feeding pipe 51 again, thereby closing the feeding pipe 51 and stopping the raw material from being filled into the sealing cover 3.

[0051] At the same time, the connecting piece 552 moves to the left under the push of the compression spring, so that the connecting piece 552 is separated from the L-shaped block 563, and at the same time, the pushing spring pushes the blocking plate 551 to the left, so that the blocking plate 551 locks the position of the No. 1 sealing plug block 52 again, thereby preventing the loading pipe 51 from connecting with the supply pipe 561.

[0052] See also Figure 5 The acceleration mechanism 6 also includes an isolation component 67 arranged inside the sealing cover 3. The isolation component 67 includes a sliding rod 671 that is symmetrical in front and back and slides up and down inside the sealing cover 3. Isolation plates 672 are fixedly installed on the two sliding rods 671 at equal intervals in the left and right directions. The isolation plate 672 is located between two adjacent No. 2 sealing plugs 54. A rotating gear 673 is rotatably arranged on the right side wall of the sealing cover 3. Racks 674 are fixedly installed on the right rear side of the front sliding rod 671 and the right front side of the follower plate 61. The front and rear racks 674 are respectively meshed with the front and rear sides of the rotating gear 673.

[0053] When the No. 1 sealing plug 52 moves downward relative to the feeding tube 51, the No. 1 sealing plug 52 drives the rear rack 674 to move downward through the follower plate 61, the rear rack 674 drives the front rack 674 to move upward through the rotating gear 673, and the front rack 674 drives the isolation plate 672 to move upward through the front sliding rod 671, so that the lower side of the isolation plate 672 is out of contact with the partition plate 4, so that the raw materials inside the sealing cover 3 can be evenly distributed under the action of gravity.

[0054] When the No. 1 sealing plug 52 moves upward relative to the feeding tube 51, the lower side of the isolation plate 672 abuts against the partition plate 4, so that the isolation plate 672 divides the raw materials inside the sealing cover 3 equally, so that when unloading, the amount of raw materials inside each unit cell of the bipolar electrolytic cell 2 is the same, thereby ensuring that the electrolysis reaction time of each unit cell is the same, thereby ensuring the efficiency of the electrolysis.

[0055] Then, the sealing cover 3 is moved downward to separate the No. 1 sealing plug 52 from the abutting column 562, so that the sealing cover 3 drives the left and right ends of the curved plate 571 to abut against the blocking strips 5734 at the corresponding positions through the partition plate 4. The blocking strips 5734 push the active push rod 5733 to move upward relative to the curved plate 571 through its reaction force, so that the active push rod 5733 drives the locking bevel 5731 to move backward, so that the locking bevel 5731 withdraws from the rectangular groove at the bottom of the partition plate 4, and the upward movement of the curved plate 571 relative to the partition plate 4 is no longer blocked.

[0056] Then, the sealing cover 3 continues to move downward, so that the reaction force of the blocking strip 5734 on the curved plate 571 pushes it to move upward relative to the partition plate 4, so that the curved plate 571 drives all the No. 2 sealing plugs 54 to move synchronously relative to the discharge pipe 53, and then the raw materials inside the sealing cover 3 are discharged in equal amounts to each unit slot of the bipolar electrolytic cell 2 through the discharge pipe 53, and the No. 2 sealing plug 54 abuts against the lower end of the rotating column 62 when moving upward, so that the rotating column 62 drives the No. 1 sealing plug 52 to press against the loading pipe 51 through the follower plate 61, thereby preventing the loading pipe 51 from leaking materials into the sealing cover 3 during the discharge process.

[0057] At the same time, the rotating column 62 drives the paddle 63 to rotate the equally separated raw materials, so that the equally separated raw materials form a vortex with the feed pipe 53 as the center, thereby generating a siphon effect, so that the raw materials inside the sealing cover 3 can be quickly fed into the bipolar electrolytic cell 2, shortening the feeding time and improving the preparation efficiency.

[0058] See also Figure 5 , Figure 6 , Figure 7 and Fig.10 The acceleration mechanism 6 also includes a rotating support rod 64 fixedly mounted at the lower part of the rotating column 62, the rotating support rod 64 is inserted into the lower part of the No. 2 sealing plug 54, and a stirring assembly 65 is arranged on the outer side of the rotating support rod 64. The stirring assembly 65 includes an inner spiral plate 651 fixedly mounted on the outer side of the lower part of the rotating support rod 64, and a vortex plate 652 is fixedly mounted on the middle and lower parts of the rotating support rod 64. The vortex lines of the upper and lower vortex plates 652 have opposite rotation directions. A mounting support 653 is fixedly mounted between the upper and lower vortex plates 652, and an outer spiral plate 654 is fixedly mounted on the mounting support 653. The rotation direction of the outer spiral plate 654 is opposite to that of the inner spiral plate 651.

[0059] When all the raw materials inside the sealing cover 3 are discharged into the interior of the bipolar electrolytic cell 2, the telescopic section of the hydraulic cylinder 58 is retracted to drive the sealing cover 3 to move upward, so that the No. 2 sealing plug 54 closes the discharge pipe 53, and at the same time, the raw materials inside are electrolyzed through the bipolar electrolytic cell 2. During this process, the sealing cover 3 continues to move upward, so that the raw materials inside the feed pipe 561 are refilled into the sealing cover 3, so that the raw materials are stored secondary during the electrolysis process, thereby shortening the loading time and accelerating the preparation efficiency.

[0060] When the bipolar electrolytic cell 2 electrolyzes the raw materials inside it, the rotating column 62 drives the inner spiral plate 651, two vortex plates 652, and outer spiral plate 654 thereon to rotate synchronously inside the unit slot of the bipolar electrolytic cell 2 through the rotating support rod 64, so that the inner spiral plate 651 lifts the raw materials in the middle of the unit slot upward, the upper vortex plate 652 pushes the raw materials lifted to the upper center position of the unit slot outward, the outer spiral plate 654 pushes the raw materials on the outside of the unit slot downward, and the lower vortex plate 652 pushes the raw materials on the lower outside toward the center of the unit slot, thereby causing the raw materials to be stirred three-dimensionally inside the unit slot, thereby preventing the raw materials from precipitating in the bipolar electrolytic cell 2 and ensuring the effect of electrolysis.

[0061] When preparing tetramethylammonium hydroxide, the present invention also includes the following steps: the first step is to retract the telescopic section of the hydraulic cylinder 58 to drive the sealing cover 3 to move upward, so that the reaction force of the movable column 562 on the No. 1 sealing plug 52 pushes it to move downward relative to the feeding pipe 51, thereby opening the feeding pipe 51, and then allowing the feeding pipe 561 to add the raw material to the interior of the sealing cover 3.

[0062] In the second step, the No. 1 sealing plug 52 drives the rotating column 62 to move downward until it rests against the upper side surface of the No. 2 sealing plug 54, so that the No. 2 sealing plug 54 is tightly fitted on the conical surface of the discharge pipe 53 through the downward push of the rotating column 62, further increasing the sealing effect of the No. 2 sealing plug 54 on the discharge pipe 53, preventing the raw materials from leaking directly from the discharge pipe 53.

[0063] The third step is to start the execution motor 661 to drive the rotating column 62 to rotate, so that the rotating column 62 stirs the raw materials inside the sealing cover 3 through the paddles 63 thereon to prevent the raw materials from settling inside the sealing cover 3.

[0064] In the fourth step, the telescopic section of the hydraulic cylinder 58 is extended to drive the sealing cover 3 to move downward, so that the No. 1 sealing plug 52 plugs the feeding pipe 51 again, thereby closing the feeding pipe 51 and stopping the raw material from being added to the inside of the sealing cover 3.

[0065] In the fifth step, the No. 1 sealing plug block 52 drives the lower side of the isolation plate 672 to rest against the partition plate 4, so that the isolation plate 672 separates the raw materials inside the sealing cover 3 in equal amounts, so that when unloading, the amount of raw materials inside each unit cell of the bipolar electrolytic cell 2 is the same, thereby ensuring that the electrolysis reaction time of each unit cell is the same, thereby ensuring the efficiency of the electrolysis.

[0066] The sixth step is to continue to move the sealing cover 3 downward so that the blocking strip 5734 pushes the curved plate 571 to drive all the No. 2 sealing plugs 54 to move synchronously relative to the discharge pipe 53, so that the raw materials inside the sealing cover 3 can be quickly and equally discharged from the discharge pipe 53 to each unit tank of the bipolar electrolytic cell 2 through the stirring of the paddle 63.

[0067] In the seventh step, the telescopic section of the hydraulic cylinder 58 is retracted to drive the sealing cover 3 to move upward, so that the raw material is filled into the sealing cover 3 again. At the same time, the bipolar electrolytic cell 2 electrolyzes the raw material inside it, and the rotating support rod 64 drives the inner spiral plate 651, the two volute plates 652, and the outer spiral plate 654 to stir the raw material in three dimensions, thereby preventing the raw material from precipitating in the bipolar electrolytic cell 2 and ensuring the effect of electrolysis.
