Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and more particularly to a drying equipment for antimony-based permeability enhancers. Background Technology

[0002] Antimony-based antireflective agents are high-performance optical coating materials. Their main active component is antimony-doped tin oxide (ATO) nanoparticles dispersed in silica sol to form a composite system. When antimony-based antireflective agents are coated onto optical glass and then heat-treated, they form a nanoporous transparent film on the optical glass, achieving excellent antireflective effects.

[0003] Currently, this coating is generally cured using a blower-type drying oven. However, existing equipment suffers from significant uneven temperature distribution: due to hot air stratification and heater layout, a temperature gradient forms from top to bottom within the oven. The upper layers of workpieces have higher temperatures and dry faster, while the middle and lower layers have lower temperatures and dry slower, leading to the following problems: Performance degradation: Differences in drying and curing rates at different temperature zones can lead to uneven internal stress within the film. The dense structure formed by rapid drying in the upper layer is not synchronized with the shrinkage of the slowly drying area in the lower layer. This stress can cause micro-cracks in the film, reduce the adhesion between the film and the glass substrate, and affect the durability and lifespan of the coating. Low pass rate: In order to ensure the minimum drying standard, it is often necessary to extend the drying time or increase the temperature, resulting in over-drying of the upper layer, increased energy consumption, and difficulty in ensuring the overall pass rate. Summary of the Invention

A first spring is fixedly connected between the sealing member and the fixing member. A pressing rod is fixedly connected inside the first connecting pipe. The pressing rod is used to press the corresponding sealing member. Each sealing member is provided with a plurality of flow holes.

[0007] Preferably, both the second connecting pipe and the first connecting pipe are provided with an inclined annular surface to improve the sealing between them.

[0008] Preferably, it further includes: The number of extrusion rings is the same as the number of second connecting tubes, and they are slidably connected to the corresponding second connecting tubes. A second spring is fixed between the extrusion ring and the corresponding second connecting tube. The second connecting tube is provided with a plurality of circumferentially evenly distributed limiting holes. The number of limiting balls is the same as the number of limiting holes, and they are slidably connected to the corresponding limiting holes. The first connecting pipe is provided with a limiting groove, which is used to limit the limiting balls.

[0009] Preferably, the diameter of the holes at both ends of the limiting hole is smaller than the diameter of the limiting ball.

[0010] Preferably, the depth of the limiting groove is less than the radius of the limiting ball.

[0011] Preferably, the placement frame is provided with a plurality of placement rollers, and an electric shaft is rotatably connected to the placement frame. A transmission module is provided between the electric shaft and the corresponding placement roller.

[0012] Preferably, it further includes: An adjusting assembly, the number of which is the same as the number of the placement rollers, is disposed on a corresponding placement roller. The adjusting assembly is used to change the position of the placement roller, and includes: A connecting frame is slidably connected to the corresponding placement frame, and the connecting frame is rotatably connected to the placement roller; Fasteners are slidably and rotatably connected to the connecting frame, and the fasteners are used to fix the connecting frame to the corresponding placement frame; A connecting block is slidably connected to the corresponding placement frame, and the connecting block is rotatably connected to the placement roller.

[0015] Compared with the prior art, the present invention has the following advantages: By combining symmetrically distributed heating plates with a placement frame and controlling the order of use of the symmetrically distributed heating plates on the same placement frame through a heating module, the present invention achieves the purpose of adjusting the heating position during the drying process, ensuring that the antimony-based antireflective agent is heated evenly throughout the drying process, thus laying the technological foundation for obtaining a high-performance antireflective film.

[0016] The electric shaft drives the placement roller to rotate the workpiece at a uniform speed around its axis, so that the entire arc surface of the workpiece can be uniformly and alternately acted on by the hot airflow. This ensures that the antimony-based antireflective agent develops a uniform nanostructure during curing, and reduces the probability of defects such as film thickness fluctuation, refractive index inconsistency, interference fringes or haze caused by uneven drying.

Detailed Implementation

[0019] First, it should be pointed out that in different described embodiments, the same components are given the same reference numerals or the same component names, and the disclosure contained throughout the specification can be applied in meaning to the same components having the same reference numerals or the same component names.

[0020] Example 1: This example proposes a drying device for antimony-based antireflective agents, aiming to solve the problem of uneven temperature distribution in existing blower-type drying ovens during normal use: due to the stratification of hot air and the layout of the heaters, a temperature gradient is formed from top to bottom within the oven. The upper layer of workpieces has a high temperature and dries quickly, while the middle and lower layers have a low temperature and dry slowly, which affects the performance of the antireflective agent on the optical glass after drying.

[0021] like Figures 1-4 As shown, the drying equipment includes: a shell 1, a control terminal on the shell 1, a heating module 2 inside the shell 1, the heating module 2 being electrically connected to the control terminal on the shell 1, two sets of symmetrically distributed positioning strips 3 fixedly connected inside the shell 1, each set of positioning strips 3 consisting of several linear arrays, several placement frames 4 on the shell 1, the positioning strips 3 at the same height jointly supporting the placement frames 4, two symmetrically distributed heating plates 5 fixedly connected to the placement frames 4 via brackets, the heating plates 5 being fixedly connected and connected to a first connecting pipe 6, symmetrically distributed vent pipes fixedly connected and connected to the heating module 2, two sets of second connecting pipes 7 fixedly connected inside the shell 1, each set of second connecting pipes 7 consisting of several linear arrays, the two sets of second connecting pipes 7 being staggered with the corresponding set of positioning strips 3, the second connecting pipes 7 being fixedly connected and connected to the corresponding vent pipes on the heating module 2, and the heating module 2 supplying hot air to the corresponding heating plate 5 through the second connecting pipes 7 and the first connecting pipes 6.

[0022] In the above scheme, the control terminal on the outer shell 1 is located on its left side; the heating module 2 is an existing device used to generate hot air; the specific number of positioning strips 3 can be selected by the staff according to the actual use; the placement frame 4 is used to place the workpiece to be dried. In this embodiment, the middle part of the placement frame 4 has a mesh structure. At the same time, the staff can freely adjust the position of the placement frame 4 according to the size of the workpiece during actual use; the heating plate 5 is provided with several air outlets to guide hot air to the surface of the workpiece and heat the workpiece; the two air pipes on the heating module 2 are symmetrically distributed on the left and right, and the heating module 2 is used to control the flow area of ​​the two air pipes; the second connecting pipe 7 on the right side supplies hot air to the heating plate 5 located below the placement frame 4 through the corresponding first connecting pipe 6, and the second connecting pipe 7 on the left side supplies hot air to the heating plate 5 located above the placement frame 4 through the corresponding first connecting pipe 6.

[0023] Furthermore, such as Figures 5-8 As shown, a fixing member 8 is fixedly connected inside the second connecting pipe 7, and a sealing member 9 is slidably connected inside the second connecting pipe 7. The sealing member 9 is located on the side of the fixing member 8 near the port of the second connecting pipe 7. Both the second connecting pipe 7 and the sealing member 9 are provided with a diameter change point. The diameter change point on the sealing member 9 is used to seal the corresponding diameter change point on the second connecting pipe 7. A first spring is fixedly connected between the sealing member 9 and the fixing member 8. A pressing rod 11 is fixedly connected inside the first connecting pipe 6. The pressing rod 11 is used to press the corresponding sealing member 9. Each sealing member 9 is provided with several flow holes.

[0024] In the above scheme, the fixing member 8 is located inside the second connecting pipe 7 on the side away from the vent pipe on the heating module 2. The port of the second connecting pipe 7 faces forward, and the port of the first connecting pipe 6 faces backward. When the second connecting pipe 7 is not connected to the first connecting pipe 6, the second connecting pipe 7 is blocked by the corresponding sealing member 9. The first spring between the sealing member 9 and the corresponding fixing member 8 is always in a compressed state, maintaining the relative position of the sealing member 9 and the corresponding second connecting pipe 7. The rear part of the extrusion rod 11 is located outside the port of the corresponding first connecting pipe 6. When the first connecting pipe 6 is connected to the second connecting pipe 7, this part is located inside the corresponding second connecting pipe 7.

[0025] Furthermore, such as Figure 8 As shown, both the second connecting pipe 7 and the first connecting pipe 6 are provided with inclined annular surfaces to improve the sealing between them.

[0026] The specific workflow of the above scheme is as follows: When this drying equipment is needed to dry optical glass coated with antimony-based antireflective agent (hereinafter referred to as workpiece), the operator first places the workpiece on the placement frame 4 (this article describes the use of two placement frames 4 as an example). After placement, the first placement frame 4 is placed on the positioning strip 3 in the appropriate position, and then the placement frame 4 is pushed backward to make it move the workpiece backward synchronously.

[0027] As the placement frame 4 moves backward, it causes the two heating plates 5 on it to move synchronously. Taking the movement of the upper heating plate 5 as an example: The heating plate 5 drives the first connecting pipe 6 on it to move, and the first connecting pipe 6 drives the extrusion rod 11 on it to move. During this process, the first connecting pipe 6 gradually enters the corresponding second connecting pipe 7. When the extrusion rod 11 contacts the corresponding sealing member 9, as the extrusion rod 11 continues to move, the extrusion rod 11 extrudes the corresponding sealing member 9, causing the sealing member 9 to move backward (the diameter change part on the sealing member 9 gradually loses contact with the diameter change part on the corresponding second connecting pipe 7), and compresses the corresponding first spring.

[0028] When the first placement frame 4 moves backward to its limit position, the inclined annular surface on the first connecting pipe 6 contacts the inclined annular surface on the second connecting pipe 7, and the diameter change point on the sealing member 9 completely loses contact with the corresponding diameter change point on the second connecting pipe 7. At this time, the sealing member 9 no longer seals the corresponding second connecting pipe 7 (making the second connecting pipe 7 connected to the corresponding vent pipe). Thus, the first placement frame 4 is installed. Subsequently, the staff completes the installation of the second placement frame 4 according to the above operation. During the installation process, the staff selects a suitable installation position (i.e., selects a suitable positioning strip 3) according to the size of the workpiece.

[0029] After both placement frames 4 are installed, the staff closes the outer shell 1 and starts the heating module 2. The heating module 2 delivers hot air through the vent pipe on the right to the two connected second connecting pipes 7 on the right (at the beginning of heating, the heating module 2 is not connected to the vent pipe on the left). The two second connecting pipes 7 on the right then guide the hot air to the corresponding heating plate 5 through the corresponding first connecting pipe 6. The hot air delivered to the heating plate 5 flows outward along the air outlet on it, thereby simultaneously heating the lower surface of all workpieces on the two placement frames 4. The workpieces then transfer the heat to the anti-reflective agent on them, achieving the drying treatment of the anti-reflective agent.

[0030] During the drying process of the workpiece, after a specified heating time (the duration of which is determined by the operator), the anti-corrosion agent on the workpiece has been initially condensed. Subsequently, the operator changes the air supply path of heating module 2 through the control terminal: The heating module 2 is connected to the left vent pipe, and the connection area between the two is gradually increased while the connection area between the heating module 2 and the right vent pipe is gradually decreased. When the two connection areas are equal, the control terminal controls the heating module 2 to stop adjusting the two connection areas. As a result, the hot air is guided to the heating plate 5 located above the workpiece. The two heating plates 5 on the upper side dry the upper surface of the corresponding workpiece, and combine with the corresponding heating plate 5 on the lower side to dry the workpiece together, thereby improving the overall drying efficiency of the workpiece.

[0031] After drying the workpiece, the operator turns off the heating module 2 and opens the outer casing 1. The two placement frames 4 are then pulled forward in sequence. As the placement frames 4 move forward, the first connecting pipe 6 on them moves forward synchronously. The first connecting pipe 6 drives the extrusion rod 11 to move synchronously, reducing the extrusion force of the extrusion rod 11 on the corresponding sealing component 9. As a result, the sealing component 9 gradually moves forward under the action of the first spring on it. When the diameter change point on the sealing component 9 re-fits with the diameter change point of the corresponding second connecting pipe 7, the sealing component 9 completes the sealing of the corresponding second connecting pipe 7. After both placement frames 4 are removed, the operator cleans and maintains the device for subsequent use.

[0032] Example 2: Based on Example 1, this example further optimizes the antimony-based clarity enhancer drying equipment proposed in the above examples.

[0033] Furthermore, such as Figures 5-8 As shown, it also includes: compression rings 12, the number of which is the same as the number of second connecting tubes 7, which are slidably connected to the corresponding second connecting tubes 7, and a second spring is fixed between the compression rings 12 and the corresponding second connecting tubes 7. The second connecting tubes 7 are provided with a plurality of circumferentially evenly distributed limiting holes 13; limiting balls 14, the number of which is the same as the number of limiting holes 13, which are slidably connected to the corresponding limiting holes 13. The first connecting tube 6 is provided with a limiting groove 15, which is used to limit the limiting balls 14.

[0034] In the above scheme, the compression ring 12 is located outside the corresponding second connecting pipe 7 and at the front of the corresponding second connecting pipe 7. The front side of the compression ring 12 is provided with an inclined ring surface. The specific number of limiting holes 13 can be selected by the staff. The limiting holes 13 are located at the front of the corresponding second connecting pipe 7. The inclined ring surface on the compression ring 12 is used to compress the limiting ball 14.

[0035] Furthermore, such as Figure 8As shown, the diameters of the holes at both ends of the limiting hole 13 are smaller than the diameter of the limiting ball 14, which is used to prevent the limiting ball 14 from sliding out of the corresponding limiting hole 13, and the depth of the limiting groove 15 is smaller than the radius of the limiting ball 14, to ensure that the shell of the limiting ball 14 is smoothly separated from the corresponding first connecting pipe 6.

[0036] The specific workflow of the above scheme is as follows: During the installation of the first placement frame 4, when the first connecting pipe 6 moves backward to contact the corresponding second connecting pipe 7, the operator moves the corresponding compression ring 12 backward, causing the compression ring 12 to compress the second spring on it during the backward movement. When the compression ring 12 moves backward to its limit position, the operator holds the compression ring 12 in that position and then continues to move the placement frame 4 backward. As the first connecting pipe 6 continues to move backward, the inclined annular surface on the first connecting pipe 6 compresses the corresponding limiting ball 14, causing the limiting ball 14 to move outward along the corresponding limiting hole 13. When the limiting ball 14 contacts the cylindrical outer wall of the first connecting pipe 6, the limiting ball 14 stops moving.

[0037] When the first connecting pipe 6 moves backward to its limit position, the limiting groove 15 on it aligns with the limiting hole 13. Then, the operator releases the compression ring 12, causing the compression ring 12 to move forward under the action of the second spring on it. During the movement, the inclined ring surface on the compression ring 12 compresses the limiting ball 14, causing the limiting ball 14 to be reset under pressure until it is partially embedded in the limiting groove 15 of the first connecting pipe 6. When the compression ring 12 is reset to its initial position, the limiting ball 14 is simultaneously reset to its initial position and cannot move due to the limitation of the inner side of the compression ring 12, thereby limiting the first connecting pipe 6 and fixing the first connecting pipe 6 and the corresponding second connecting pipe 7, improving the stability and sealing of the connection between the two, and reducing the volume of hot gas leaking outward.

[0038] When the drying process is complete and the placement frame 4 needs to be removed, the operator moves the compression ring 12 backward as described above. After the compression ring 12 moves backward to its limit position again, the placement frame 4 is pulled forward so that the limiting groove 15 squeezes the limiting ball 14 again, thereby releasing the limitation on the first connecting pipe 6.

[0039] Example 3: Based on Example 2, this example further optimizes the antimony-based clarity enhancer drying equipment proposed in the above examples.

[0040] Furthermore, such as Figure 3 and Figures 9-12 As shown, a number of placement rollers 18 are provided on the placement frame 4, and an electric shaft 19 is rotatably connected to the placement frame 4. A transmission module is provided between the electric shaft 19 and the corresponding placement roller 18.

[0041] In the above scheme, the number and diameter of the placement rollers 18 on the same placement frame 4, as well as the distance between two adjacent placement rollers 18, can be selected by the operator. In the figure and text, two placement rollers 18 are used as an example. In this embodiment, the placement rollers 18 are rotatably connected to the corresponding placement frame 4, and the electric shaft 19 is located behind the placement rollers 18. The transmission module is a bevel gear set. In this embodiment, one of the bevel gears in each set is fixedly connected to the electric shaft 19, and the other is fixedly connected to the placement roller 18. During the use of this device, the operator places the workpiece on the placement roller 18 and then dries the workpiece according to the above operation. During the drying process, the operator starts the electric shaft 19, which drives the corresponding placement roller 18 to rotate through the transmission module. During the rotation of the placement roller 18, the workpiece on it is moved laterally, changing the contact position between the workpiece and the placement roller 18, thereby improving the uniformity of heating on the lower side of the workpiece and improving the overall drying efficiency.

[0042] Example 4: Based on Example 3, this example further optimizes the antimony-based clarity enhancer drying equipment proposed in the above examples.

[0043] Furthermore, such as Figures 9-12 As shown, it also includes: an adjustment component, the same number as the placement rollers 18, the adjustment component is set on the corresponding placement roller 18, the adjustment component is used to change the position of the placement roller 18, the adjustment component includes: a connecting frame 17, slidably connected to the corresponding placement frame 4, the connecting frame 17 is rotatably connected to the placement roller 18; a fastener 20, slidably and rotatably connected to the connecting frame 17, the fastener 20 is used to fix the connecting frame 17 on the corresponding placement frame 4; and a connecting block 21, slidably connected to the corresponding placement frame 4, the connecting block 21 is rotatably connected to the placement roller 18.

[0044] In the above scheme, in this embodiment, the placement roller 18 and the placement frame 4 are not directly connected. The connecting frame 17 is located behind the placement roller 18. The fastener 20 is an existing device, and the figure shows a nut and bolt as an example. The nut is located on the lower side of the placement frame 4, and the position of the connecting frame 17 is fixed by the friction between the nut and the placement frame 4. The connecting block 21 is located in front of the placement roller 18. In this embodiment, the bevel gear on the electric shaft 19 is connected to its spline, and the bevel gear on the electric shaft 19 is rotatably connected to the corresponding connecting frame 17. During the drying process of the workpiece, the operator adjusts the two placement rollers 18 on the same placement frame 4 according to the size of the workpiece. The specific position (changing the distance between the two placement rollers 18) is as follows: Rotate the nut to separate the nut from the lower side of the placement frame 4, that is, to contact the fastener 20 to fix the connecting frame 17. Then, the operator can move the placement roller 18 left and right. During this process, the placement roller 18 drives the connecting frame 17 and the connecting block 21 on it to move synchronously, so that the two move along the placement frame 4. The connecting frame 17 and the placement roller 18 together drive the corresponding transmission module to move, so that the bevel gear on the placement roller 18 moves along its spline groove. When the position of the placement roller 18 is adjusted, the operator rotates the nut to fix the moved connecting frame 17, thereby fixing the placement roller 18 in the moved position.

[0045] Example 5: Based on Example 4, this example further optimizes the antimony-based clarity enhancer drying equipment proposed in the above examples.

[0046] Furthermore, such as Figures 9-12 As shown, the placement frame 4 is slidably connected to two sets of symmetrically distributed connectors 22. Each set of connectors 22 contains several connectors. The connectors 22 are detachably connected to a sliding rod 23. The sliding rod 23 is rotatably connected to a rotating shaft. The rotating shaft on the sliding rod 23 is fixedly connected to a pressing roller 24. The pressing roller 24 is used to press the workpiece. The connectors 22 are threadedly connected to a fastening screw 25. The fastening screw 25 is used to fix the sliding rod 23 by friction.

[0047] In the above scheme, the number of each connecting piece 22 can be selected by the staff. Under normal conditions, the sliding rod 23 is located in the corresponding connecting piece 22 and can move up and down along the corresponding connecting piece 22. In actual use, the staff can choose whether to remove the sliding rod 23 as needed. When the extrusion roller 24 is in contact with the workpiece, it is used to extrude and fix the workpiece. When the sliding rod 23 moves down to the limit position relative to the corresponding connecting piece 22, the height of the lower side of the extrusion roller 24 is lower than the height of the upper side of the placement roller 18.

[0048] Furthermore, such as Figures 9-12As shown, the projection of the extrusion roller 24 onto the horizontal plane is located inside the projection of the placement frame 4 onto the horizontal plane, ensuring that the extrusion roller 24 does not collide with the placement frame 4 during movement, thereby ensuring contact between the extrusion roller 24 and the workpiece.

[0049] The specific workflow of the above scheme is as follows: During the drying process of the workpiece using this device, if the workpiece to be dried is arc-shaped, the operator adjusts the distance between the two placement rollers 18 according to the radius of curvature of the workpiece. After the distance between the two placement rollers 18 is adjusted, the operator moves the two connecting pieces 22 in sequence, so that the two connecting pieces 22 move along the placement frame 4, thereby changing the position of the two extrusion rollers 24. When the two extrusion rollers 24 are located in the middle between the two placement rollers 18, the operator stops moving the connecting pieces 22, and then places the workpiece on the two placement rollers 18 (with the inside of the workpiece facing upwards and the anti-reflective agent coated on the inside of the workpiece).

[0050] After placing the workpiece, the operator loosens the two fastening screws 25 in sequence to release the fixation of the two sliding rods 23. Then, the operator moves the sliding rods 23 downwards in sequence, causing the corresponding pressing rollers 24 to move downwards synchronously until the pressing rollers 24 move downwards and are in close contact with the upper surface of the workpiece. The operator then stops moving the sliding rods 23 and tightens the two fastening screws 25 in sequence to fix the sliding rods 23 and pressing rollers 24 in the current position. The workpiece is then dried according to the above operation. During the drying process, the electric shaft 19 is started according to the above operation. The electric shaft 19 drives the two placement rollers 18 to rotate synchronously. During the rotation of the two placement rollers 18, they jointly move the workpiece (causing the workpiece to rotate around its axis), thereby increasing the uniformity of the anti-reflective agent distribution on the workpiece. At the same time, during the rotation of the workpiece, the two pressing rollers 24 jointly limit the workpiece and maintain the stability of the workpiece's position.

[0051] After drying is complete, the operator shall follow the above procedure to release the fastening screw 25 from the sliding rod 23, and then follow the above procedure to remove the workpiece from the two placement rollers 18 for subsequent use.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
