Description

Technical Field

[0001] This invention relates to the field of glass production technology, specifically to a processing technology and equipment for ITO conductive glass. Background Technology

[0002] ITO conductive glass is made by depositing a layer of silicon dioxide as a barrier layer on a sodium-calcium-based or silicon-boron-based substrate glass, and then depositing a layer of indium tin oxide film (commonly known as ITO film, also known as transparent electrode). Indium tin oxide (ITO) is an N-type semiconductor with good conductivity at room temperature and good transmittance of visible light. It is one of the key materials for producing LCD screens and touch screens. The reason why LCDs can display specific graphics is that the transparent conductive film on the conductive glass is etched to form electrodes of specific shapes. After the upper and lower conductive glass are made into a liquid crystal cell, an appropriate voltage signal is applied to these electrodes, causing the liquid crystal molecules with dipole moments to align in a specific direction under the action of the electric field, thereby displaying a pattern corresponding to the electrode wavelength. With the rapid development of LCD screen and touch screen technology, how to make the ITO film thickness more uniform and controllable, thereby improving the performance of the ITO film, is the problem that this invention needs to solve.

[0003] Therefore, there is an urgent need for a low-cost ITO conductive glass processing technology and equipment with good ITO film formation effect to solve the above problems. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide an ITO conductive glass processing technology and equipment: by setting a conveying threaded rod and slide rail between the mounting box and the fixed table, the moving table can move left and right, facilitating loading and unloading and continuous operation. Then, the glass substrate is adsorbed and fixed by a positioning mechanism, and then the height of the glass substrate is adjusted by a lifting and rotating mechanism to cooperate with the scraper, so that the ITO sol on the glass substrate can be evenly scraped onto the surface of the glass substrate when the glass substrate rotates. Then, the scraped ITO sol is cured in a drying oven to form a pre-coating layer. Finally, the pre-coating layer is annealed to form an ITO film. This solves the problems of uneven film thickness and difficulty in control of existing ITO films, which affect the quality of ITO conductive glass, and the high cost of existing ITO film coating equipment.

[0010] As a further aspect of the present invention: a placement groove is provided on the bottom side of the moving platform, a recycling box is placed in the inner cavity of the placement groove, a filter screen is installed on the top of the inner cavity of the recycling box, a plurality of material collection grooves are provided on the bottom of the inner cavity of the forming groove, a discharge pipe is installed on the bottom of the material collection groove, the discharge pipe is installed in the inner cavity of the moving platform, and the bottom end of the discharge pipe penetrates the top of the placement groove and is located above the recycling box.

[0011] As a further aspect of the present invention: a heating mesh is installed in the inner cavity of the drying oven, the height of the heating mesh being greater than the height of the scraper, and the height of the scraper being greater than the height of the positioning mechanism.

[0012] As a further aspect of the present invention: the lifting and rotating mechanism includes an installation cylinder, a lifting cylinder and a rotating motor. The lifting cylinder is installed at the bottom of the inner cavity of the installation cylinder, and the rotating motor is installed at the top of the lifting cylinder. The output shaft of the rotating motor is connected to the bottom center position of the positioning mechanism.

[0013] As a further aspect of the present invention: the positioning mechanism includes a mounting plate, connecting arms, and an electric suction cup. The mounting plate is mounted on the output shaft of a rotary motor. Several connecting arms are mounted on the side wall of the mounting plate. The several connecting arms are arranged in a circular array. An electric suction cup is mounted on the top of one end of each connecting arm and on the top of the mounting plate.

[0014] As a further aspect of the present invention: a processing method for ITO conductive glass, comprising the following steps:

[0015] Step 1: After cutting the glass plate according to specifications, ultrasonically wash it with a 50-75% ethanol solution and then blow it dry with nitrogen to obtain the glass substrate.

[0016] Step 2: Mix InCl3·4H2O and SnCl4·5H2O at a molar ratio of 9:1 to obtain a mixture. Dissolve the mixture in anhydrous ethanol at a mass ratio of 1:5-10. Mix at room temperature and stir on a magnetic stirrer for 7-8 hours. Then add 5-15 times the weight of deionized water to the mixture and stir to prepare a homogeneous solution. Let the homogeneous solution stand at room temperature for 48 hours to form ITO sol.

[0017] Step 3: Add ITO sol to the glue tank of the ITO conductive glass processing equipment, then place the glue tank in the placement chamber and place the feed pipe in the inner cavity of the glue tank. Place the glass substrate on the positioning mechanism from the loading area and fix the lower surface of the glass substrate using an electric suction cup.

[0018] Step 4: Start the drive motor. The drive motor will rotate the conveying threaded rod. Since the conveying threaded rod is threadedly connected to the threaded groove, the moving table moves on the slide rail through the slide groove until the moving table abuts against the mounting box. At this time, the material discharge head is located directly above the center of the forming groove.

[0019] Step 5: Start the delivery pump. The delivery pump will filter the ITO sol in the glue tank through the filter sleeve and the feed pipe and then extract it. It will be transported to the discharge head through the delivery pipe and then dripped from the bottom of the discharge head to the center of the upper surface of the glass substrate.

[0020] Step 6: Start the adjustment motor. The operation of the adjustment motor drives the drive gear to rotate. Since the drive gear and the driven gear are meshed and connected, the scraper blades are rotated and the two scraper blades abut against each other at the center of the upper surface of the glass substrate.

[0021] Step 7: Start the lifting cylinder of the lifting and rotating mechanism. The moving rod of the lifting cylinder extends and pushes the rotary motor to rise, thereby pushing the positioning mechanism to rise, so as to bring the glass substrate closer to the scraper. Start the rotary motor. The rotary motor drives the positioning mechanism to rotate, thereby making the glass substrate rotate, which makes it easier for the scraper to evenly scrape the ITO sol located at the center of the upper surface of the glass substrate onto the glass substrate.

[0022] Step 8: After the ITO sol coating is completed, start the heating grid. The heating grid releases heat, and the ITO sol dries and forms a pre-coating as the glass substrate rotates. The moving stage returns to its initial position, and the glass substrate with the pre-coating is unloaded from the unloading area. Then, the glass substrate with the pre-coating is placed in an annealing condition at 460-500℃ for 60-80 minutes to form an ITO film, thus obtaining ITO conductive glass.

[0023] The beneficial effects of this invention are:

[0024] This invention discloses an ITO conductive glass processing technology and equipment. The equipment utilizes a conveying threaded rod and slide rail between a mounting box and a fixed platform, allowing the moving platform to move left and right for easy loading and unloading and continuous operation. A positioning mechanism then adsorbs and fixes the glass substrate. A lifting and rotating mechanism adjusts the height of the glass substrate to align with a scraper, enabling the uniform application of ITO sol to the substrate surface as it rotates. The applied ITO sol is then cured in a drying oven to form a pre-coating layer. Finally, the pre-coating layer is annealed to form an ITO film. This conductive glass processing equipment sequentially completes the processes of loading, fixing, sol application, scraping, drying, and automatic unloading between the mounting box and the fixed platform. It boasts a high degree of automation, reducing labor costs and significantly improving work efficiency. Furthermore, the lifting and rotating mechanism allows adjustment of the distance between the glass substrate and the scraper, enabling the adjustment of the ITO film thickness and number of layers according to production needs, thereby altering and improving the conductivity of the conductive glass and enhancing its quality.

[0025] During the processing of this conductive glass, the scraper blade scrapes the excess ITO sol on the glass substrate into the inner cavity of the forming tank. The ITO sol then passes through the collection tank and discharge pipe onto the filter screen, and after filtration, it enters the inner cavity of the recycling box for collection and reuse, reducing resource waste and lowering production costs.

A lifting and rotating mechanism 122 is embedded in the center of the forming groove 129. A positioning mechanism 104 is installed on the top of the lifting and rotating mechanism 122. A scraper 121 is provided in the inner cavity of the forming groove 129.

[0039] Slide rails 113 are installed between the bottom of both ends of one side of the mounting box 101 and the fixed platform 102. A conveying threaded rod 114 is rotatably installed between the middle of one side of the mounting box 101 and the fixed platform 102. A drive motor 112 is installed at the bottom of one side of the fixed platform 102. The output shaft of the drive motor 112 is connected to one end of the conveying threaded rod 114. Slide grooves 126 are opened on both sides of the bottom of the moving platform 103. The slide grooves 126 and the slide rails 113 are mating components. A threaded groove 127 is opened through the bottom of the moving platform 103. The threaded groove 127 is threadedly connected to the conveying threaded rod 114.

[0040] The mounting box 101 is installed on the top of the support platform 109. A placement chamber 115 is provided at the connection between the mounting box 101 and the support platform 109. A glue tank 110 is placed in the placement chamber 115. A delivery pump 118 is installed inside the glue tank 110. A feed pipe 116 is installed at the input end of the delivery pump 118.

One end of the delivery pipe 119 is located in the inner cavity of the mounting plate 111 and is connected to the inner cavity of the discharge head 120.

[0041] An adjustment motor 130 is embedded in the top of the moving table 103. An installation chamber 131 is opened on the side wall of the forming groove 129. A driven gear 133 is rotatably installed in the inner cavity of the installation chamber 131 via a rotating shaft. The driven gear 133 is installed on one end of the scraper plate 121. The driven gear 133 meshes with the driving gear 132. The driving gear 132 is sleeved on the output shaft of the adjustment motor 130.

[0042] The scraper 121 in the conductive glass processing equipment is connected to the driven gear 133. The driven gear 133 is meshed with the driving gear 132. Therefore, the position of the scraper 121 can be adjusted by adjusting the motor 130. When loading or unloading is required, the scraper 121 abuts against the inner wall of the forming groove 129, which will not affect the loading or unloading. When ITO sol needs to be coated, the scraper 121 can be adjusted to the center of the glass substrate to achieve coating.

[0043] A placement groove 128 is provided on the bottom side of the moving platform 103. A recycling box 125 is placed in the inner cavity of the placement groove 128.

The bottom end of the discharge pipe 124 passes through the top of the placement groove 128 and is located above the recycling box 125.

[0044] During the processing of this conductive glass processing equipment, the scraper 121 scrapes the excess ITO sol on the glass substrate into the inner cavity of the forming tank 129, so that the ITO sol falls onto the filter screen 141 through the collection tank 123 and the discharge pipe 124. After filtration, it enters the inner cavity of the recycling box 125, where it can be collected and reused, reducing resource waste and lowering production costs.

[0045] A heating grid 134 is installed in the inner cavity of the drying oven 108. The height of the heating grid 134 is greater than the height of the scraper 121, and the height of the scraper 121 is greater than the height of the positioning mechanism 104.

[0046] The lifting and rotating mechanism 122 includes a mounting cylinder 135, a lifting cylinder 136, and a rotating motor 137.

[0047] The positioning mechanism 104 includes a mounting plate 138, connecting arms 139, and an electric suction cup 140. The mounting plate 138 is mounted on the output shaft of the rotary motor 137. Several connecting arms 139 are mounted on the side wall of the mounting plate 138. The several connecting arms 139 are arranged in a circular array. An electric suction cup 140 is mounted on the top of one end of the connecting arm 139 and the top of the mounting plate 138.

They are set on the mounting cylinder 135, which runs through the middle of the molding groove 129 and the upper end is higher than the top of the molding groove 129, so that the ITO sol will not enter the interior of the mounting cylinder 135 and damage other parts.

[0049] A loading robot can be installed at the loading area 105, and a loading conveyor can be installed near the loading robot. A unloading robot can be installed at the unloading area 106, and an unloading conveyor can be installed near the unloading robot.

[0050] Example 2:

[0051] Please see Figure 1-8 As shown, this embodiment is a processing technology for ITO conductive glass, including the following steps:

[0052] Step 1: After cutting the glass plate according to specifications, ultrasonically wash it with a 50-75% ethanol solution and then dry it with nitrogen to obtain the glass substrate.

[0053] Step 2: Mix InCl3·4H2O and SnCl4·5H2O at a molar ratio of 9:1 to obtain a mixture. Dissolve the mixture in anhydrous ethanol at a mass ratio of 1:7.5. Stir the mixture on a magnetic stirrer for 8 hours at room temperature. Then add 10 times the weight of deionized water to the mixture and stir to prepare a homogeneous solution. Let the homogeneous solution stand at room temperature for 48 hours to form ITO sol.

[0054] Step 3: Add ITO sol to the glue tank 110 of the ITO conductive glass processing equipment, then place the glue tank 110 in the placement chamber 115, and place the feed pipe 116 in the inner cavity of the glue tank 110. Place the glass substrate on the positioning mechanism 104 from the loading area 105. The loading method can be manual loading or loading robot loading. Then, use the electric suction cup 140 to fix the lower surface of the glass substrate.

[0055] Step 4: Start the drive motor 112. The drive motor 112 drives the conveying threaded rod 114 to rotate. Since the conveying threaded rod 114 is threadedly connected to the threaded groove 127, the moving table 103 moves on the slide rail 113 through the slide groove 126 until the moving table 103 abuts against the mounting box 101. At this time, the material discharge head 120 is located directly above the center of the forming groove 129.

[0056] Step 5: Start the delivery pump 118. The delivery pump 118 operates to filter the ITO sol in the glue box 110 through the filter sleeve 117 and the feed pipe 116 and then extract it. It is then transported through the delivery pipe 119 to the discharge head 120 and then dripped from the bottom of the discharge head 120 to the center of the upper surface of the glass substrate.

[0057] Step 6: Start the adjustment motor 130. The operation of the adjustment motor 130 drives the drive gear 132 to rotate. Since the drive gear 132 is meshed with the driven gear 133, it drives the scraper 121 to rotate. The two scraper blades 121 abut against each other at the center of the upper surface of the glass substrate.

[0058] Step 7: Start the lifting cylinder 136 of the lifting and rotating mechanism 122. The movable rod of the lifting cylinder 136 extends and pushes the rotary motor 137 to rise, thereby pushing the positioning mechanism 104 to rise, thereby pushing the glass substrate closer to the scraper 121. Start the rotary motor 137. The rotary motor 137 runs and drives the positioning mechanism 104 to rotate, thereby realizing the rotation of the glass substrate. Then, the scraper 121 is used to evenly scrape the ITO sol located at the center of the upper surface of the glass substrate onto the glass substrate.

[0059] Step 8: After the ITO sol coating is completed, start the heating grid 134. The heating grid 134 releases heat, and the glass substrate is dried and shaped by the ITO sol during rotation to form a pre-coating. The coating can be repeated multiple times to form a multi-layer pre-coating. The moving stage 103 returns to the initial position, and the glass substrate with the pre-coating is unloaded from the unloading area 106. The unloading method can be manual or by a unloading robot. Then, the glass substrate with the pre-coating is annealed at 480°C for 70 minutes to form an ITO film and obtain ITO conductive glass.

The output shaft of the rotary motor (137) is connected to the bottom center of the positioning mechanism (104). The positioning mechanism (104) includes a mounting plate (138), connecting arms (139), and an electric suction cup (140). The mounting plate (138) is mounted on the output shaft of a rotary motor (137). Several connecting arms (139) are mounted on the side wall of the mounting plate (138). The several connecting arms (139) are arranged in a circular array. An electric suction cup (140) is mounted on the top of one end of each connecting arm (139) and on the top of the mounting plate (138). A heating mesh (134) is installed in the inner cavity of the drying box (108). The height of the heating mesh (134) is greater than the height of the scraper (121), and the height of the scraper (121) is greater than the height of the positioning mechanism (104).

2. A processing technology for ITO conductive glass, characterized in that... The ITO conductive glass processing equipment according to claim 1 includes the following steps: Step 1: Cut the glass plate to specifications, then ultrasonically wash it, and then dry it with nitrogen to obtain the glass substrate; Step 2: ITO sol was prepared using InCl3·4H2O and SnCl4·5H2O as raw materials; Step 3: Add ITO sol to the glue tank (110) of the ITO conductive glass processing equipment, place the feed pipe (116) in the inner cavity of the glue tank (110), place the glass substrate on the positioning mechanism (104) from the loading area (105), and fix the lower surface of the glass substrate. Step 4: The conveying thread rod (114) rotates to move the moving table (103) on the slide rail (113) until the discharge head (120) is located directly above the center of the forming groove (129); Step 5: The delivery pump (118) operates to filter and extract the ITO sol in the glue tank (110), and then deliver it to the discharge head (120), and then drip it from the bottom of the discharge head (120) to the center of the upper surface of the glass substrate. Step 6: Adjust the motor (130) to rotate the scraper (121) so that the two scraper (121) abut against each other at the center of the upper surface of the glass substrate; Step 7: The movable rod of the lifting cylinder (136) of the lifting and rotating mechanism (122) extends to push the rotary motor (137) to rise, thereby pushing the glass substrate closer to the scraper (121). The rotary motor (137) rotates to make the glass substrate rotate, thereby using the scraper (121) to uniformly scrape the ITO sol located at the center of the upper surface of the glass substrate onto the glass substrate. Step 8: After the ITO sol coating is completed, start the heating grid (134). The heating grid (134) releases heat, and the glass substrate dries and shapes the ITO sol during the rotation process to form a pre-coating. The glass substrate containing the pre-coating is then unloaded from the unloading area (106). After that, the glass substrate containing the pre-coating is annealed to form an ITO film, thus obtaining ITO conductive glass.
