Description

Technical Field

[0001] The present invention belongs to the technical field of glass etching, and in particular relates to a spray etching device and method for manufacturing an anti-glare layer of AG glass. Background Art

[0002] AG glass (Anti-Glare Glass) converts mirror reflection into diffuse reflection by forming a micron-level rough structure (such as randomly distributed pits or protrusions) on the glass surface, thereby reducing ambient light interference and improving display clarity.

[0003] During the production process, AG glass needs to be aligned for etching, but the inventors found that the existing etching method is to lay the glass horizontally and then use multiple conveyor wheels to rotate and transport the glass, so that the glass is etched, cleaned and dried in sequence. In this way, only one piece of glass can be etched at a time, resulting in low overall utilization, which affects the overall etching efficiency.

[0004] Therefore, the existing structure and defects are studied and improved, and a spray etching device and method for manufacturing an AG glass anti-glare layer are provided, in order to achieve a more practical purpose. Summary of the Invention

[0036] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be another element centered thereon. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3 , a spray etching device for manufacturing an anti-glare layer of AG glass 2, includes an etching box 1, a conveying mechanism 4 and a fixing mechanism 3. The etching box 1 is provided with a through cavity, and the through cavity is sequentially provided with an etching area, a cleaning area and a drying area. The fixing mechanism 3 is used to fix the glass 2 in a tree shape and evenly. The conveying mechanism 4 is arranged in the through cavity, and is used to drive the fixing mechanism 3 to pass through the etching area, the cleaning area and the drying area in sequence. The etching area is provided with a plurality of tree-shaped and evenly distributed etching tubes 12, the etching tubes 12 are located on both sides of the glass 2, and the etching tubes 12 are provided with etching holes for spray etching, the cleaning area is provided with a plurality of tree-shaped and evenly distributed cleaning tubes 14, the cleaning tubes 14 are located on both sides of the glass 2, and the cleaning tubes 14 are provided with cleaning holes for spray cleaning, the fixing mechanism 3 is provided with a through area for the etching tubes 12 and the cleaning tubes 14 to pass through, and the drying area is provided with a dry hot air blower.

[0040] The design of evenly distributing multiple glasses 2 in a tree shape, combined with the tree-like design of the etching tube 12 and the cleaning tube 14, can fully utilize the space, so that the entire device can etch multiple glasses 2 at the same time, thereby fully improving the etching efficiency.

[0041] See also Figure 2 and Figure 3 In this embodiment, the fixing mechanism 3 includes a fixing base 31, and a plurality of fixedly connected fixing rods 32 are provided on the fixing base 31. Every four fixing rods 32 form a fixing area for fixing the glass 2. The fixing rods 32 are each provided with a plurality of fixedly connected positioning rods 35. The positioning rods 35 are provided with a rotatable roller 33, and the glass 2 is squeezed and fixed by the roller 33.

[0042] The roller 33 is designed to be rotatable, so that the roller 33 can not only fix the glass 2, but also drive the glass 2 to move up and down during the etching process by rotating the roller 33. In this way, the etching liquid can contact the surface of the glass 2 more evenly, and it can also effectively prevent the presence of the positioning rod 35 and the roller 33, which causes the etching liquid to be unable to contact some surfaces of the glass 2, so that the etching liquid spraying on the glass 2 is more even, thereby improving the etching quality.

[0043] See also Figure 3 、 Figure 4 and Figure 7 In this embodiment, a drive shaft 37 is fixedly connected to the bottom of the fixed base 31. A support ring plate 36 is rotatably connected to the outer side of the drive shaft 37 and used to support the fixed base 31. A first gear 370 is fixedly connected to the bottom of the drive shaft 37. A first drive gear 168 is rotatably movable back and forth within the drying area, and the first drive gear 168 meshes with the first gear 370. The support ring plate 36 has a plurality of annularly distributed rotation grooves, each of which is rotatably connected to a rotating wheel 361. The rotating wheel 361 contacts the bottom of the fixed base 31, making the fixed base 31 more efficient and labor-saving during rotation.

[0044] The design of the supporting ring plate 36, the driving shaft 37, the first gear 370 and the first driving gear 168 enables the fixing mechanism 3 to move to the drying area by controlling the first driving gear 168 to engage with the first rack, and then driving the driving shaft 37 to rotate through the first gear 370, so that the fixed base 31 can rotate, so that the multiple glasses 2 can also rotate synchronously. In this way, the centrifugal force can be utilized through rotation to separate the liquid from the glass 2 more quickly during the drying process, thereby improving the drying efficiency.

[0045] See also Figure 3 、 Figure 4 and Figure 5In this embodiment, a plurality of evenly distributed blowing holes 34 are provided on both the upper and lower sides of the positioning rod 35. A driving groove 374 is provided in the middle of the driving shaft 37. A driving plate 371 that can move up and down is provided in the driving groove 374. A first one-way air inlet 372 is provided at the bottom of the driving groove 374 below the driving plate 371. A rotating shaft 38 is provided in the middle of the driving groove 374. The driving plate 371 passes through the rotating shaft 38. A first guide groove 382 is provided in the middle of the rotating shaft 38. A first one-way exhaust duct 38 connected to the first guide groove 382 is provided on the rotating shaft 38 below the driving plate 371. Hole 383, a guide groove 311 is provided in the fixed base 31, the first guide groove 382 is communicated with the guide groove 311, and the other end of the guide groove 311 is communicated with the corresponding blowing hole, and the rotating shaft 38 located above the driving plate 371 is provided with a second one-way exhaust hole 384 connected to the first guide groove 382, ​​and a second guide groove 381 is also provided in the rotating shaft 38, and a second one-way air inlet hole 386 connected to the second guide groove 381 is provided on the rotating shaft 38 located below the driving plate 371, and the other end of the second guide groove 381 is located in the driving groove 374 above the driving plate 371.

[0046] When the etching solution reacts with the material, bubbles (such as hydrogen during metal etching) or suspended debris may be generated, which will adhere to the surface and cause uneven etching. The blowing method of the blowing hole can use the airflow to blow away impurities and debris in time. The design of the blowing hole, the driving plate 371 and the driving groove 374 can use the up and down movement of the driving plate 371. Through the cooperation of the first one-way exhaust hole 383, the first one-way air inlet hole 372, the second one-way exhaust hole 384 and the second one-way air inlet hole 386, the airflow can be automatically transported to the blowing hole, so that the blowing hole can automatically blow air to the surface of the glass 2. The roller 33 can drive the glass 2 to move up and down, so that the blowing hole can blow the surface of the glass 2 more evenly.

[0047] See also Figure 5 and Figure 6In this embodiment, a first hydraulic rod 373 is fixedly connected in the driving groove 374, and the end of the first hydraulic rod 373 is connected to the driving plate 371. A connecting pipe 312 is provided at the liquid inlet end of the first hydraulic rod 373. A roller 33 groove is provided on the fixed rod 32, and a connecting shaft 331 is rotatably connected in the roller 33 groove. The connecting shaft 331 is fixedly connected to the roller 33. An adjusting groove 354 is provided in the fixed rod 32, and the end of the connecting shaft 331 is located in the adjusting groove 354. An adjusting gear 353 fixedly connected to the connecting shaft 331 is provided in the adjusting groove 354, and an adjusting rack 352 slidably connected and meshing with the adjusting gear 353 is provided in the adjusting groove 354. A second hydraulic rod 351 is fixedly connected in the adjusting groove 354, and the end of the second hydraulic rod 351 is fixedly connected to the adjusting gear 353. The connecting pipe 312 is connected to the liquid inlet end of the second hydraulic rod 351.

[0048] The design of the first hydraulic rod 373, the second hydraulic rod 351 and the connecting pipe 312 can make the second hydraulic rod 351 able to synchronously extend and retract during the up and down movement of the driving plate 371 through hydraulic transmission. The design of the adjusting gear 353 and the adjusting rack 352 can make the roller 33 synchronously rotate forward and reverse periodically during the up and down movement of the driving plate 371. This design can make the roller 33 drive the glass 2 to move up and down during the blowing process, so that the blowing hole can blow air to the surface of the glass 2 more evenly.

[0049] See also Figure 4 、 Figure 5 and Figure 7 In this embodiment, a second gear 39 is fixedly connected to the end of the rotating shaft 38. The rotating shaft 38 is provided with a reciprocating thread, connecting the rotating shaft 38 to the drive plate 371 via the reciprocating thread. Both the etching and cleaning zones are provided with a second drive gear 167 that can rotatably move back and forth, meshing with the second gear 39. A first extrusion plate 164 that can move back and forth and is used to compress and secure the first gear 370 is provided in both the etching and cleaning zones. A second extrusion plate 165 that can move back and forth and is used to compress and secure the second gear 39 is provided in the drying zone. Sealing hoses 385 are fixedly connected at both the upper and lower ends of the drive plate 371 and are used to seal the connection. The extended ends of the sealing hoses 385 are rotatably and sealingly connected to the corresponding rotating shaft 38, ensuring a tight seal at the connection between the drive plate 371 and the rotating shaft 38.

[0050] The design of the reciprocating thread, the second gear 39, the first gear 370, the first extrusion plate 164 and the second extrusion plate 165 is such that when in the etching area, it is only necessary to squeeze the first gear 370 with the first extrusion plate 164, so that the first gear 370 will not rotate, and the second driving gear 167 is engaged with the second gear 39, so that the second driving gear 167 can drive the second gear 39 to rotate, so that the rotating shaft 38 rotates, and the up and down movement of the driving plate 371 can be realized. The up and down movement of the driving plate 371 can realize the periodic forward and reverse rotation of the roller 33 and the automatic blowing of the blowing hole 34, without driving the fixed base 31 to rotate at this time. The same principle applies to the cleaning area, because the cleaning area and the etching area only need to blow air to the surface of the glass 2 And control the up and down movement of the glass 2. When in the drying area, the second squeezing plate 165 squeezes and fixes the second gear 39. At this time, the rotating shaft 38 will not rotate, and the first driving gear 168 can drive the driving shaft 37 to rotate through the first gear 370, so that the entire fixed base 31 can rotate automatically. At this time, the rotation of the glass 2 can be realized, and the automatic drying of the glass 2 can be achieved by using centrifugal force. At the same time, the driving plate 371 can also be moved up and down, so that during the rotation of the glass 2, air can also be blown and the glass 2 can be moved up and down. In this way, the dry and hot air flow blown by the blowing hole 34 can make the drying efficiency of the glass 2 faster. At the same time, the up and down movement of the glass 2 can also effectively prevent the situation where the liquid on the surface of the glass 2 cannot be separated when the roller 33 does not move.

[0051] See also Figure 4 and Figure 7 In this embodiment, a support plate 16 is provided in the through cavity, and a first motor 161, a second motor 162 and a third motor 163 are provided on the support plate 16. The output end of the first motor 161 is connected to the corresponding second drive gear 167, the output end of the second motor 162 is connected to the corresponding second drive gear 167, and the output end of the third motor 163 is connected to the corresponding first drive gear 168. An electric hydraulic push rod 166 is provided in the through cavity for driving the support plate 16 to move back and forth.

[0052] See also Figure 7 In this embodiment, the first extrusion plate 164 and the second extrusion plate 165 are both fixedly mounted on the support plate 16. The first extrusion plate 164 is flush with the first drive gear 168, and the second extrusion plate 165 is flush with the second drive gear 167. This enables the first drive gear 168, the second drive gear 167, the first extrusion plate 164, and the second extrusion plate 165 to move back and forth.

[0053] See also Figure 1 、 Figure 2In this embodiment, the conveying mechanism 4 includes a conveying ring bar 42 and a conveying plate 41. The conveying ring bar 42 can rotatably pass through the cavity. There are two conveying ring bars 42 and multiple conveying plates 41. Both ends of the conveying plate 41 are connected to the corresponding conveying ring bars 42. The conveying plate 41 is provided with a through-hole 43 for the drive shaft 37 to pass through. A rotatable conveying wheel is provided in the conveying ring bar 42, and a mounting plate for fixed support is provided on the outside of the conveying wheel. The conveying wheel is rotatably connected to the mounting plate, and a conveying motor 44 is provided on the mounting plate to drive the conveying ring bar 42 to rotate.

[0054] See also Figure 2 In this embodiment, a first box 11 for storing etching liquid is provided on one side of the etching box 1. The first box 11 is provided with a delivery pump. The output end of the delivery pump is provided with a first tube, and the first tube is connected to the etching tube 12. A second box 13 for storing cleaning liquid is provided on one side of the etching box 1. The second box 13 is provided with a delivery pump. The output end of the delivery pump is provided with a second tube, and the second tube is connected to the cleaning tube 14.

[0055] See also Figure 2 In this embodiment, a collection box 15 for recovering the etching liquid and the cleaning liquid is provided in the through cavity, and the collection box 15 is located between the conveying rings 42.

[0056] When using this application:

[0057] First, place the glass 2 into the fixed area between the fixing rods 32, and use the rollers 33 to squeeze and fix the glass 2. Then, place the fixed base 31 on the conveying plate 41 between the conveying rings 42, and insert the drive shaft 37 into the through hole 43. Then, start the conveying motor 44 to drive the fixed base 31 to move toward the etching box 1.

[0058] When the fixed base 31 is located at the set position of the etching area, the etching tubes 12 are evenly distributed on both sides of the glass 2, the delivery pump is started, and the etching liquid is sprayed and etched on the surface of the glass 2 through the etching hole. At the same time, the electric hydraulic push rod 166 is controlled to move the support plate 16, so that the second driving gear 167 above the first motor 161 is engaged with the second gear 39 below the fixed base 31 (the engagement method can be to slowly approach and control the rotation speed of the second gear 39 to rotate slowly. After engagement, the rotation speed of the second gear 39 is controlled to resume. This is an existing technology, so no excessive steps are performed. ), at this time, the first extrusion plate 164 can squeeze and fix the first gear 370, so the rotation of the second gear 39 can automatically drive the rotation of the rotating shaft 38, and the rotation of the rotating shaft 38 can automatically drive the driving plate 371 to move up and down through the characteristics of the reciprocating thread. The driving plate 371 moves up and down, and the blowing hole can continuously blow air to the surface of the glass 2 through the cooperation of the first one-way exhaust hole 383, the first one-way air inlet hole 372, the second one-way exhaust hole 384 and the second one-way air inlet hole 386, so as to timely blow away impurities generated during the etching process on the surface of the glass 2;

[0059] At the same time, the up and down movement of the driving plate 371 can drive the adjustment gear 353 to periodically reciprocate through the hydraulic transmission of the first hydraulic rod 373 and the second hydraulic rod 351, and drive the roller 33 to periodically rotate forward and reverse through the adjustment gear 353, thereby driving the glass 2 to periodically move up and down. The up and down movement of the glass 2 can not only make the etching liquid contact the surface of the glass 2 more uniform, reduce the blocking effect of the fixed rod 32 on the glass 2, but also make the blowing of the blowing hole more uniform during the blowing process.

[0060] When etching is completed, the support plate 16 is restored to its initial position. At this time, the conveying motor 44 is moved to move the fixed base 31 to the set position of the cleaning area, and the conveying pump in the second box 13 is controlled to automatically spray the cleaning liquid on the surface of the glass 2. At this time, the support plate 16 is controlled to move to the set position again, so that the second driving gear 167 on the second motor 162 is engaged with the second gear 39 under the fixed base 31. At this time, the first squeezing plate 164 squeezes and fixes the corresponding first gear 370, and then the second motor 162 can be used to drive the driving plate 371 in the fixed base 31 to move up and down. Through the same principle, the blowing hole can blow air to the glass 2 while also controlling the up and down movement of the glass 2. When the fixing mechanism 3 moves to the cleaning area after etching is completed, the next fixing mechanism 3 is automatically fed into the etching area along with the conveying mechanism 4, and while the support plate 16 moves to the set position, the up and down movement of the glass 2 in the etching area and the automatic blowing of the blowing hole 34 are controlled.

[0061] When the cleaning is completed, the etching of the glass 2 in the previous etching area is completed, and the support plate 16 is controlled to restore the initial position, so that the fixed rod 32 mechanism of the cleaning is automatically moved to the set position of the drying area, and then the support plate 16 is controlled to move. At this time, the first driving gear 168 above the third motor 163 is engaged with the first gear 370, and the first squeezing plate 164 squeezes and fixes the second gear 39. With the start of the third motor 163, the first gear 370 can drive the driving shaft 37 to rotate, thereby controlling the fixed base 31 to automatically rotate, and through the rotation, the centrifugal force is used to make the glass after cleaning be dried. 2. The liquid on the surface of the glass 2 can be quickly separated. Since the first squeezing plate 164 fixes the second gear 39, the rotating shaft 38 does not rotate. In this way, the reciprocating thread can also drive the driving plate 371 to move up and down, so that during the rotation of the glass 2, the blowing hole 34 can also blow air to the surface of the glass 2. Since the drying area is full of dry hot air, in this way, the dry hot air can be directly introduced between the glass 2. During the rotation, the dry hot air can also quickly dry the liquid on the surface of the glass 2. In addition, with the up and down movement of the glass 2, the surface of the glass 2 can be dried more evenly.

[0062] After the drying is completed, the fixing mechanism 3 is moved to the outside of the etching box 1 and then the fixing mechanism 3 is taken out manually.

[0063] A spray etching method for manufacturing an anti-glare layer of AG glass 2, using the spray etching device for manufacturing an anti-glare layer of AG glass 2, comprises the following steps:

[0064] S1: First, place the glass 2 to be etched vertically and evenly in the fixing mechanism 3, and then place the fixing mechanism 3 on the conveying mechanism 4. Then, start the conveying mechanism 4 to drive the fixing mechanism 3 into the etching box 1.

[0065] S2: When the fixing mechanism 3 is located in the etching area, the etching tube 12 passes through the passing area so that the etching holes are located on the corresponding sides of the glass 2, and then the etching liquid in the etching holes sprays and etches the glass 2;

[0066] S3: When the etching is completed, the fixing mechanism 3 is moved to the cleaning area, and the surface of the glass 2 is sprayed and cleaned using the cleaning holes;

[0067] After S4 cleaning is completed, the fixing mechanism 3 is placed in the drying area, and the surface of the glass 2 is dried by the dry hot air flow generated by the dry hot blower. After the drying is completed, the fixing mechanism 3 is driven to separate from the etching box 1 by the conveying mechanism 4, and the etching is completed at this time.
