Description

Technical Field

[0001] The invention relates to the technical field of quantum dot film preparation, and in particular to a device for preparing a uniformly coated quantum dot film. Background Art

[0002] Quantum dot film is usually prepared by pressing together a multi-layer structure. The preparation of quantum dot film is generally to apply a quantum dot film solution with adhesive effect on a layer of high water vapor barrier film, and then cover another layer of high water vapor barrier film on the quantum dot film solution. Finally, the two layers of high water vapor barrier film are pressed together to complete the preparation of quantum dot film. However, quantum dot solution is fluid. Therefore, during the preparation process, the surface of quantum dot solution is not smooth, resulting in bubbles between the upper high water vapor barrier film and the quantum dot solution. Existing quantum dot film preparation devices generally directly press the high water vapor barrier film and the quantum dot film solution. Therefore, there are bubbles in the finished quantum dot film after pressing. After the quantum dot film solution is dried, the space inside the bubbles is reduced or even disappears, resulting in wrinkles on the surface of the quantum dot film, which in turn affects the performance of the quantum dot film.

[0032] See also Figure 3 , Figure 8 and Fig. 9The first conveyor belt group 110 is fixedly connected to a front-to-back symmetrically distributed missing gear 301 through a transmission shaft, the bracket 101 is fixedly connected to a front-to-back symmetrically distributed first elastic telescopic rod 302, the telescopic ends of the front-to-back symmetrically distributed first elastic telescopic rod 302 are commonly fixedly connected to a first slide 303, a front-to-back symmetrically distributed rack portion is provided on the left side of the first slide 303, the rack portion of the first slide 303 cooperates with the adjacent missing gear 301, when the missing gear 301 is meshed with the rack portion of the first slide 303, the symmetrically distributed missing gears 301 simultaneously drive the first slide 303 to move downward, when After the missing gear 301 loses engagement with the rack part of the first slide 303, the first elastic telescopic rod 302 pops out to drive the first slide 303 to move upward and reset.

[0033] See also Figure 8 and Fig. 9 The bracket 101 is slidably connected to a collecting shell 401 that is symmetrically distributed front and back near the first slide 303. The collecting shell 401 is used to collect the excess quantum dot solution flowing out of the lower water vapor high barrier membrane. A first bidirectional telescopic rod 402 is fixedly connected between the collecting shells 401 that are symmetrically distributed front and back, wherein the first bidirectional telescopic rod 402 is an electrically controlled telescopic rod and is electrically connected to the control panel, and a telescopic frame 403 is fixedly connected between the collecting shells 401 that are symmetrically distributed front and back. The telescopic end of the first bidirectional telescopic rod 402 drives the two collecting shells 401 to move, so as to collect the excess quantum dot solution on the water vapor high barrier membranes of different widths.

[0034] When the operator needs to use the device to prepare the quantum dot film, the operator first places the two high water vapor barrier films on the two second rotating rollers 201 symmetrically distributed up and down, and passes the high water vapor barrier films around the adjacent third rotating roller 202, the adjacent fourth rotating roller 204 and the adjacent first rotating roller 106 in turn. Then the operator pulls the upper and lower layers of the high water vapor barrier film through the upper and lower symmetrically distributed rolling rollers 113. After completing the above preparatory steps, the operator turns on the four electric control motors 203 through the control panel. The output shaft of the electric control motor 203 drives the adjacent fourth rotating roller 204 to rotate. The fourth rotating roller 204 drives the second gear set 206 symmetrically distributed front and back to rotate through its transmission belt. The second gear set 206 symmetrically distributed front and back simultaneously drives the stirring The blade fan 207 rotates, and the second gear set 206 drives the first rotating roller 106 on the upper side to rotate through its transmission belt, and pulls the water vapor high barrier membranes on the upper and lower sides to move the water vapor high barrier membrane to the right. At this time, the operator adds the quantum dot solution into the shell 205, and the stirring blade fan 207 rotates to stir the quantum dot solution in the shell 205 to avoid the deposition of quantum dots in the quantum dot solution, so that the quantum dots are evenly dispersed in the quantum dot solution. As the water vapor high barrier membrane moves to the right, the quantum dot solution gradually flows out through the first opening 2051 to the water vapor high barrier membrane on the lower side. The operator turns on the upper and lower symmetrically distributed rolling rollers 113 through the driving member to rotate the rolling rollers 113. Finally, the upper and lower layers of the water vapor high barrier membrane and the quantum dot solution in the middle are pressed together by the rolling rollers 113.

[0035] In the process that the high water vapor barrier membrane on the lower side drives the quantum dot solution thereon to move to the right, the operator turns on the electric-controlled telescopic rod 102 through the control panel, the telescopic end of the electric-controlled telescopic rod 102 symmetrically distributed front and back on the upper side is initially extended, and the telescopic end of the electric-controlled telescopic rod 102 symmetrically distributed front and back on the lower side is initially contracted, firstly the telescopic end of the electric-controlled telescopic rod 102 on the lower side is gradually extended, the telescopic end of the electric-controlled telescopic rod 102 drives the adjacent scraper 104 to move through the adjacent rack 103, the scraper 104 on the lower side presses the conveyor belt of the second conveyor belt group 111 (the high water vapor barrier membrane on the lower side passes between the first conveyor belt group 110 and the second conveyor belt group 111), the lower scraper 104 moves to the left along the rightmost end of the upper scraper 104 to scrape and press the conveyor belt of the second conveyor belt group 111, and the lower scraper 104 squeezes the conveyor belt of the second conveyor belt group 111 to press the high water vapor barrier membrane on the lower side. The quantum dot solution on the diaphragm is scraped flat, and then when the telescopic end of the lower electrically-controlled telescopic rod 102 drives the lower scraper 104 to move to the limit position through the adjacent rack 103, the telescopic end of the upper electrically-controlled telescopic rod 102 drives the upper scraper 104 to move to the right through the adjacent rack 103. After the telescopic end of the upper electrically-controlled telescopic rod 102 shrinks to the limit position, the telescopic end of the upper electrically-controlled telescopic rod 102 drives the upper scraper 104 to move to the left through the adjacent rack 103, and the upper scraper 104 scrapes the conveyor belt of the first conveyor belt group 110 to squeeze and scrape the quantum dot solution flat. In this reciprocating cycle, the surface of the quantum dot solution is scraped flat to avoid uneven surfaces of the quantum dot solution between the two layers of high water vapor barrier membranes, resulting in bubbles inside after pressing. After the bubbles are dried, the space inside the bubbles shrinks or even disappears, resulting in an uneven surface of the quantum dot film, thereby affecting the performance of the quantum dot film.

[0036] In the process that the telescopic end of the electric telescopic rod 102 drives the adjacent scraper 104 to move through the adjacent rack 103 (the order of movement of the electric telescopic rod 102 is: first, the output end of the lower electric telescopic rod 102 extends, then the output end of the upper electric telescopic rod 102 contracts, then the upper electric telescopic rod 102 extends, and finally the output end of the lower electric telescopic rod 102 contracts, and this cycle drives the corresponding rack 103 to move), when the lower rack 103 moves to the left to drive the adjacent meshing one-way gear 105 to rotate clockwise, the one-way gear 105 drives the first rotating roller 106 on the lower side to rotate clockwise through its transmission belt. At this time, the high water vapor barrier membrane is pulled to move to the right. Taking the two one-way gears 105 on the front side as an example, since the first one-way gear 105 on the front side drives its shaft to rotate clockwise at this time, the second one-way gear 105 on the front side cannot rotate.

[0037] When the upper rack 103 moves rightward to drive the adjacent meshing one-way gear 105 to rotate clockwise, the one-way gear 105 drives the lower first rotating roller 106 to rotate clockwise through its transmission belt, and the first one-way gear 105 on the front side cannot rotate.

[0038] When the upper rack 103 moves to the left, the one-way gear 105 cannot rotate counterclockwise to drive the first rotating roller 106 on the lower side to rotate through its transmission belt, and the first rotating shaft 107, the first gear set 108 and the second rotating shaft 109 cannot rotate. Therefore, the conveyor belts of the first conveyor belt group 110 and the conveyor belts of the second conveyor belt group 111 cannot move. The rack 103 drives the adjacent scraper 104 to scrape and press the conveyor belts of the first conveyor belt group 110, and the first conveyor belt group 110 squeezes the high water vapor barrier film on the lower side and flattens it.

[0039] When the lower rack 103 moves to the right, the one-way gear 105 rotates counterclockwise and cannot drive the first rotating roller 106 on the lower side to rotate through its transmission belt, the first rotating shaft 107, the first gear group 108 and the second rotating shaft 109 cannot rotate, the conveyor belts of the first conveyor belt group 110 and the conveyor belts of the second conveyor belt group 111 cannot move, and the rack 103 drives the adjacent scraper 104 to scrape and press the conveyor belts of the second conveyor belt group 111, and the second conveyor belt group 111 squeezes the high water vapor barrier film on the lower side to flatten it, and because the one-way gear 105 is in transmission cooperation with the first rotating roller 106, the number of times the scraper 104 scrapes a unit of high water vapor barrier film can be adjusted by adjusting the diameter of the first rotating roller 106.

[0040] During the reciprocating movement of the scraper 104, the first rotating roller 106 on the lower side drives the first rotating shaft 107 to rotate through the transmission belt, and the first rotating shaft 107 drives the second rotating shaft 109 to rotate through the symmetrically distributed first gear set 108, and the first rotating shaft 107 and the second rotating shaft 109 respectively drive the first conveyor belt group 110 and the second conveyor belt group 111 to rotate, so that the scraper 104 on the upper side scrapes and presses the conveyor belt of the first conveyor belt group 110, and the scraper 104 on the lower side scrapes and presses the conveyor belt of the second conveyor belt group 111, and the quantum dot solution is evenly spread on the lower water vapor high barrier membrane through the extrusion of the first conveyor belt group 110 and the second conveyor belt group 111, and the conveyor belts of the first conveyor belt group 110 and the second conveyor belt group 111 both squeeze the quantum dot solution on the lower water vapor high barrier membrane to achieve the scraping of the quantum dot solution on the lower water vapor high barrier membrane.

[0041] During the rotation of the first conveyor belt group 110, the left rotating shaft of the first conveyor belt group 110 drives the symmetrically distributed missing gear 301 to rotate. When the missing gear 301 is engaged with the rack portion of the first slide 303, the symmetrically distributed missing gear 301 simultaneously drives the first slide 303 to move downward. The first slide 303 simultaneously drives the sticking plate 304 and the impact portion 305 to move downward. The first slide 303 drives the telescopic ends of the symmetrically distributed first elastic telescopic rods 302 to move downward and contract. When the missing gear 301 and the gear of the first slide 303 are engaged, the first slide 303 drives the sticking plate 304 and the impact portion 305 to move downward. After the strip loses engagement, the first elastic telescopic rod 302 pops out and drives the first slide 303 to reset. When the first slide 303 simultaneously drives the sticky plate 304 and the impact part 305 to move upward and reset, the first slide 303 drives the sticky plate 304 to move upward to adhere to the dust on the upper water vapor barrier film, and the first slide 303 drives the impact part 305 to impact the lower water vapor barrier film, thereby vibrating out the bubbles in the quantum dot solution on the lower water vapor barrier film, thereby reducing the content of dust and bubbles between the upper and lower layers of water vapor barrier film after pressing.

[0042] During the process of scraping the quantum dot solution, excess quantum dot solution will flow out along the front and rear sides of the lower water vapor high barrier membrane to the corresponding collection shell 401. When the quantum dot solution in the collection shell 401 reaches a certain amount, the operator recycles it. The operator controls the extension amount of the telescopic end of the first bidirectional telescopic rod 402 through the control panel. The telescopic end of the first bidirectional telescopic rod 402 drives the telescopic frame 403 to extend and retract, and the telescopic end of the first bidirectional telescopic rod 402 drives the symmetrically distributed collection shell 401 to move, so as to adjust the distance between the two collection shells 401, so as to collect excess quantum dot solution on the lower water vapor high barrier membrane of different widths, prevent the quantum dot solution from flowing to the lower side of the lower water vapor high barrier membrane, and reduce the adhesion amount of the quantum dot solution at the edge of the lower water vapor high barrier membrane.

[0043] After the operator has completed the pressing of the quantum dot film, the operator resets the device through the control panel, turns off the power of the device, and then cleans the device for the next use.

[0044] Example 2: Based on Example 1, please refer to Figure 7 , Fig.10 and Fig.11, also includes an adjustment component 5, the adjustment component 5 is used to adjust the amount of the quantum dot solution glued, the adjustment component 5 is arranged on the left side of the bracket 101, the adjustment component 5 includes a rotating disk 501 symmetrically distributed front and back, a recess is arranged on the right side of the rotating disk 501, the rotating disk 501 is rotatably connected to the end of the adjacent second rotating roller 201, the end of the lower second rotating roller 201 is fixedly connected with a flexible block uniformly distributed in the circumferential direction, the rotating disk 501 is fixedly connected with a flexible block uniformly distributed in the circumferential direction, the flexible block of the rotating disk 501 is limitedly matched with the flexible block of the adjacent second rotating roller 201, the lower left part of the bracket 101 is fixedly connected with a second elastic telescopic rod 502 symmetrically distributed front and back, and the second elastic telescopic rod 502 symmetrically distributed front and back is jointly fixedly connected to the support frame 50 3. A second bidirectional telescopic rod 504 is fixedly connected to the lower side of the bracket 101. The telescopic ends of the second bidirectional telescopic rod 504, which are symmetrically distributed above and below, are fixedly connected with clamps 505 for measuring the thickness of the water vapor high barrier film roll. An elastic member is fixedly connected between the telescopic end of the second bidirectional telescopic rod 504 and its fixed part, wherein the elastic member is a compression spring and its initial state is a compressed state. The elastic force of the second elastic telescopic rod 502 cannot drive the elastic member of the second bidirectional telescopic rod 504 to expand and contract. A trigger part 506 symmetrically distributed front and back is provided on the left side of the support frame 503. The trigger part 506 is limitedly matched with the recessed part of the adjacent rotating disk 501. When the rotating disk 501 rotates, the recessed part of the rotating disk 501 squeezes the adjacent trigger part 506, so that the support frame 503 moves to the right, and the support frame 503 moves to the right. 03 is fixedly connected with a trigger block 507 on the left side, and the trigger block 507 penetrates into the fixed part of the second bidirectional telescopic rod 504, and the telescopic end of the second bidirectional telescopic rod 504 is squeezed and matched with the trigger block 507. When the trigger block 507 moves to the left and resets, the telescopic ends symmetrically distributed up and down in the second bidirectional telescopic rod 504 squeeze the trigger block 507, so that the trigger block 507 cannot be completely reset. The support frame 503 is fixedly connected with a blocking plate 508, and the blocking plate 508 is slidably connected to the shell 205. The blocking plate 508 is blocked and matched with the first opening 2051. The distance that the trigger block 507 moves to the right is twice the thickness of the high water vapor barrier film. The trigger block 507 moves to the right and drives the blocking plate 508 to move to the right. The distance that the blocking plate 508 moves is The size of 51 can be adjusted to achieve the adjustment of the amount of glue applied to the quantum dot solution of the water vapor high barrier membrane with different thicknesses. The bracket 101 is fixedly connected with the fixed columns 509 which are symmetrically distributed front and back. The position of the rotating disk 501 close to the adjacent fixed column 509 is fixedly connected with the limit pin 510. A spring plate 511 is arranged in the fixed column 509, wherein the spring plate 511 is composed of a rectangular plate and a spring. The spring plate 511 is limitedly matched with the adjacent limit pin 510. The resistance between the flexible block of the rotating disk 501 and the flexible block of the adjacent second rotating roller 201 is greater than the resistance of the adjacent trigger part 506 to the adjacent rotating disk 501. The resistance of the spring plate 511 to the adjacent limit pin 510 is greater than the resistance between the flexible block of the adjacent rotating disk 501 and the flexible block of the adjacent second rotating roller 201.When the second rotating roller 201 drives the lower water vapor high barrier membrane to rotate 360°, the rotating disk 501 drives the adjacent limiting pin 510 to rotate 360°, so that the limiting pin 510 contacts and squeezes the rectangular plate of the adjacent spring plate 511, and the rectangular plate of the spring plate 511 slides along the adjacent fixed column 509. The spring of the spring plate 511 is compressed to compensate for the rotation angle of the rotating disk 501, so that the rotating disk 501 can rotate 360°. At this time, due to the limitation of the limiting pin 510 and the adjacent spring plate 511, the lower second rotating roller 201 cannot drive the adjacent rotating disk 501 to rotate through its flexible block, so the rotating disk 501 stops rotating.

A sliding plate 703 is slidably connected inside the fixed plate 702. The connecting rod 701 is fixedly connected to the adjacent sliding plate 703, and the sliding plate 703 is slidably matched with the first opening 2051. When it is necessary to glue and press the high-barrier water vapor membranes of different widths, the collecting shell 401 drives the adjacent sliding plate 703 to move through the adjacent connecting rod 701, and the sliding plate 703 slides along the adjacent fixed plate 702 to adjust the opening width of the first opening 2051.

[0046] See also Fig.12 and Fig.13The support 101 is rotatably connected to a centrifugal disk 801 symmetrically distributed front and back at a position close to the shell 205. The centrifugal disk 801 is transmission-connected to the adjacent fourth rotating roller 204 through a third gear set 802. The third gear set 802 is used to amplify the transmission ratio between the adjacent fourth rotating roller 204 and the adjacent centrifugal disk 801. A plurality of centrifugal blocks 803 uniformly distributed circumferentially are slidably connected in the centrifugal disk 801. A first limiting frame 804 symmetrically distributed front and back is slidingly connected to the left side of the shell 205. A plurality of centrifugal blocks 803 uniformly distributed circumferentially are fixedly connected to the adjacent first limiting frame 804 through a rope. A second limiting frame 805 is slidingly connected to the left side of the shell 205. The second limiting frame 805 is limitedly matched with the symmetrically distributed first limiting frame 804. An elastic member is fixedly connected between the second limiting frame 805 and the shell 205, wherein the elastic member is a tension spring and its initial state is a stretched state. A second opening 2052 is provided on the left side of the shell 205, and the second limiting frame 805 is slidably matched with the second opening 2052. The lower side of the first limiting frame 804 is provided with an inclined surface distributed in a linear array. When the first limiting frame 804 moves, the elastic member of the second limiting frame 805 contracts, and the second limiting frame 805 moves upward along the symmetrically distributed inclined surface on the lower side of the first limiting frame 804, so that the second limiting frame 805 and the second opening 2052 are misaligned and circulated. When the rotation speed of the centrifugal disk 801 increases and the traction speed of the high water vapor barrier membrane increases, the flow volume of the second opening 2052 increases accordingly, thereby realizing adaptive adjustment of the amount of glue deposited by the quantum dot solution. The upper side of the sliding plate 703 is fixedly connected to a limiting portion 806, and the limiting portion 806 is slidably matched with the second opening 2052. The sliding plate 703 drives the adjacent limiting portion 806 to move to adjust the opening width of the second opening 2052.

[0047] See also Figure 1 and Fig.14 The lower rolling roller 113 is rotatably connected to the limit block 901 symmetrically distributed front and back, the right side of the bracket 101 is fixedly connected to the third limit frame 902 symmetrically distributed front and back and the slide frame 903 symmetrically distributed front and back, the right side of the support frame 503 is fixedly connected to the second slide 904, the right side of the second slide 904 is provided with symmetrically distributed inclined surfaces, the slide frame 903 is slidably connected to the second slide 904, the upper rolling roller 113 is rotatably connected to the bracket 101, and the lower rolling roller 113 is rotatably connected to the bracket 101. The pressure roller 113 is connected to the bracket 101 by sliding and rotation, and the limit block 901 is limited by the adjacent second slide 904. When the support frame 503 moves to the right, the support frame 503 drives the second slide 904 to move to the right, and the limit block 901 moves downward along the inclined surface of the adjacent second slide 904. The limit block 901 drives the lower side rolling roller 113 to move downward, so that when the thickness of the high water vapor barrier film changes, the distance between the rolling rollers 113 increases accordingly.

[0048] When the operator needs to press the high vapor barrier films of different thicknesses, the operator needs to adjust the amount of the quantum dot solution. After the high vapor barrier film is fixed and pulled with the above steps, the second rotating roller 201 on the lower side drives the high vapor barrier film on the lower side to rotate 360°. The second rotating roller 201 on the lower side drives the symmetrically distributed rotating disk 501 to rotate through its flexible block. The concave part of the rotating disk 501 first squeezes the adjacent trigger part 506, so that the support frame 503 moves to the right, and the symmetrically distributed second elastic stretch roller 201 moves to the right. The telescopic end of the retracting rod 502 contracts, and the support frame 503 drives the trigger block 507 to move to the right. The initial position of the trigger block 507 is to penetrate into the fixed part of the second bidirectional telescopic rod 504. The trigger block 507 moves to the right to make the two telescopic ends of the second bidirectional telescopic rod 504 move towards each other. The initial state of the elastic part of the second bidirectional telescopic rod 504 is a compressed state. At this time, the elastic part of the second bidirectional telescopic rod 504 drives its symmetrically distributed telescopic ends to move in the direction of the trigger block 507, and the two clamps 505 clamp the high water vapor barrier membrane on the lower side.

[0049] When the second rotating roller 201 drives the lower side water vapor high barrier membrane to rotate 360°, the rotating disk 501 drives the adjacent limit pin 510 to rotate 360°, so that the limit pin 510 contacts and squeezes the rectangular plate of the adjacent spring plate 511, and the rectangular plate of the spring plate 511 slides along the adjacent fixed column 509, and the spring of the spring plate 511 is compressed to compensate for the rotation angle of the rotating disk 501, so that the rotating disk 501 can rotate 360°.

[0050] After the rotating disk 501 rotates 360°, due to the obstruction of the rectangular plate of the spring plate 511, the second rotating roller 201 on the lower side cannot drive the adjacent rotating disk 501 to rotate through its flexible block. The flexible block of the second rotating roller 201 on the lower side and the flexible block of the adjacent rotating disk 501 are squeezed and contracted, so that the second rotating roller 201 no longer drives the symmetrically distributed rotating disks 501 to rotate. The telescopic end of the second elastic telescopic rod 502 is reset, so that the support frame 503 drives the symmetrically distributed triggering parts 506 to move leftward and reset, and the trigger block 506 is reset. 07 moves to the left, but since the elastic force of the second elastic telescopic rod 502 cannot drive the elastic part of the second bidirectional telescopic rod 504 to expand and contract, the clamp 505 cannot be reset, and the trigger block 507 cannot be reset. The distance that the trigger block 507 moves to the right is twice the thickness of the high water vapor barrier membrane. The trigger block 507 moves to the right and drives the sealing plate 508 to move to the right. The size of the first opening 2051 is adjusted by the moving distance of the sealing plate 508, so as to realize the adjustment of the glue amount of the quantum dot solution of the high water vapor barrier membrane with different thicknesses.

[0051] When it is necessary to glue and press high-vapor barrier films of different widths, the operator controls the extension amount of the telescopic end of the first bidirectional telescopic rod 402 through the control panel. The collecting shell 401 drives the adjacent sliding plate 703 to move through the adjacent connecting rod 701, and the sliding plate 703 slides along the adjacent fixed plate 702 to adjust the opening width of the first opening 2051.

[0052] When the operator needs to adjust the rotation speed of the traction of the high water vapor barrier membrane, taking the acceleration of the rotation speed of the fourth rotating roller 204 as an example, the fourth rotating roller 204 drives the symmetrically distributed third gear set 802 to rotate, and the third gear set 802 drives the adjacent centrifugal disk 801 to rotate. The third gear set 802 is used to amplify the transmission ratio between the adjacent fourth rotating roller 204 and the adjacent centrifugal disk 801. When the rotation speed of the centrifugal disk 801 is accelerated, the adjacent centrifugal blocks 803 slide toward the circumferential position of the adjacent centrifugal disk 801 under the action of centrifugal force, and the circumferentially distributed centrifugal blocks 803 drive the adjacent first limiting frames 804 to move through ropes, and the symmetrically distributed first limiting frames 804 move in the opposite direction, and the symmetrically distributed first limiting frames 804 lose the limit on the second limiting frame 805, so that the elastic member of the second limiting frame 805 contracts, and the second limiting frame 805 is The elastic member of the positioning frame 805 is initially in a stretched state, and the elastic member of the second limiting frame 805 drives it to move upward, and the second limiting frame 805 and the second opening 2052 are staggered for circulation. When the rotation speed of the centrifugal disk 801 increases and the traction speed of the high water vapor barrier membrane increases, the second opening 2052 is opened, and as the rotation speed of the centrifugal disk 801 increases, the flow volume of the second opening 2052 gradually increases, to prevent the first opening 2051 from not meeting the feeding amount of the quantum dot solution after the traction speed of the high water vapor barrier membrane increases, resulting in insufficient content of the quantum dot solution on the quantum dot membrane, thereby realizing adaptive adjustment of the amount of the quantum dot solution. At the same time, when the width of the first opening 2051 is adjusted as mentioned above, the sliding plate 703 drives the adjacent limiting part 806 to move to adjust the opening width of the second opening 2052.

[0053] During the process of the support frame 503 moving to the right, the support frame 503 drives the second slide 904 to move to the right along the symmetrically distributed slide frame 903, so that the inclined surface of the second slide 904 moves to the right, and the limit block 901 moves downward along the inclined surface of the adjacent second slide 904, and the limit block 901 moves downward along the adjacent third limit frame 902. The limit block 901 drives the lower side rolling roller 113 to move downward, so that when the thickness of the high water vapor barrier film changes, the distance between the rolling rollers 113 increases accordingly, and the symmetrically distributed motors respectively drive the adjacent rolling rollers 113 to rotate, so as to realize the pressing of high water vapor barrier films of different thicknesses.

[0054] After the operator has completed the pressing of the quantum dot film, the operator resets the device through the control panel, turns off the power of the device, and then cleans the device for the next use.
