Description

Technical Field

[0001] This invention relates to the field of substrate glass manufacturing technology, and more specifically to an adjustment device for cleaning glass. Background Technology

[0002] Substrate glass, an indispensable substrate material in the manufacture of modern electronic devices, is widely used in high-tech products such as displays, solar panels, and touch screens. Its excellent physical and chemical properties, such as high light transmittance, good flatness, and outstanding heat and corrosion resistance, make substrate glass an ideal choice for these high-precision electronic devices. With the rapid development of the electronics industry, the performance requirements for substrate glass are constantly increasing.

[0003] Polishing is a crucial step in the production of glass substrates. However, glass powder and polishing slurry inevitably adhere to the glass substrate. These residues not only affect the cleanliness of the glass substrate but may also cause a series of problems in subsequent processes. For example, they may interfere with the uniformity of coatings or plating, leading to a decline in optical performance; or, under prolonged high-temperature processing, the residues may trigger chemical reactions, causing cracks or bubbles to appear on the surface of the glass substrate, ultimately rendering it a reject.

[0004] Therefore, after polishing the glass substrate, it is necessary to clean the polished glass. Current glass cleaning methods generally involve using a roller brush to clean the glass surface and apply water resistance. However, the long sponge roller cannot be adjusted vertically, and the roller brush must be manually adjusted by rotating gears, posing a significant safety hazard. Furthermore, the manual operation is cumbersome and cannot be adjusted in real time, which negatively impacts the quality of the glass.

[0005] Therefore, how to design a glass cleaning device that can be automatically adjusted in real time has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic position adjustment device and method for cleaning glass, so as to overcome the problem that traditional methods cannot adjust in real time.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution: An automatic position adjustment device for cleaning glass includes a rotating assembly, a telescopic rod, a servo motor, a controller, a time sensor, a displacement sensor, and long shafts disposed on both sides of the glass to be cleaned. A roller brush is fitted on a long shaft, and rotating components are connected to both ends of the long shaft. A servo motor is connected to the outer wall of the long shaft via a telescopic rod. The telescopic rod extends and retracts in a direction perpendicular to the glass to be cleaned. The servo motor is connected to a controller, which is also connected to a displacement sensor and a time sensor. The displacement sensor is located at the bottom of the telescopic rod, and the time sensor is located at the bottom of the long shaft.

[0008] A further improvement of the present invention is that it also includes a support base, and the two ends of the long shaft are respectively secured on the support base by a rotating component.

[0009] A further improvement of the present invention is that the support base has a U-shaped structure.

[0010] A further improvement of the present invention is that the rotating component is a bearing.

[0011] A further improvement of the present invention is that the roller brush is a sponge roller.

[0012] A further improvement of the present invention is that the length of the long shaft is greater than the length of the roller brush, and the length of the roller brush is greater than the length of the glass to be cleaned.

[0013] A further improvement of this invention is that the displacement sensor adopts a Keyence IG-028 displacement sensor.

[0014] A further improvement of this invention is that the time sensor used is a Keyence FU-97S time sensor.

[0015] The present invention also provides an automatic positional adjustment method for cleaning glass, employing the device described above, wherein the long shafts disposed on both sides of the glass to be cleaned are a first long shaft and a second long shaft, respectively, the roller brush sleeved on the first long shaft is an upper roller brush, and the roller brush sleeved on the second long shaft is a lower roller brush, comprising the following steps: The optimal time range T and displacement X of the glass to be cleaned passing through the roller brush are preset, where T1≤T≤T2; The time t for the glass to be cleaned to pass through the roller brush is counted by the time sensor. When t < T1, the upper and lower roller brushes have not been pressed into the glass to be cleaned. The servo motor is controlled to rotate forward, so that the telescopic rod drives the upper and lower roller brushes to move in the direction close to the glass to be cleaned. The movement distance x is sensed by the displacement sensor. When x = X, the servo motor is turned off. When T1≤t≤T2, the servo motor remains off; When t > T2, the servo motor is reversed, causing the telescopic rod to drive the upper and lower roller brushes to move away from the glass to be cleaned. The displacement sensor senses the moving distance x. When x = X, the servo motor is turned off. Where T1 is the preset minimum time for the glass to be cleaned to reach the cleaning standard, and T2 is the preset maximum time for the glass to be cleaned to reach the cleaning standard.

[0016] A further improvement of this invention is that the optimal time T is in the range of 7.8s≤T≤8.3s, and the displacement X is 0.05 ~ 0.1mm.

[0017] Compared with the prior art, the positive and progressive effects of the present invention are as follows: The automatic position adjustment device for cleaning glass provided by this invention includes a rotating component, a telescopic rod, a servo motor, a controller, a time sensor, a displacement sensor, and long shafts disposed on both sides of the glass to be cleaned. The long shafts and rotating component enable the cleaning of the glass substrate. The coordination of the telescopic rod, servo motor, controller, displacement sensor, and time sensor ensures that the roller brush contacts the glass substrate at the appropriate time and position, achieving automatic adjustment of the roller brush's position. This replaces the traditional manual adjustment method, enabling real-time adjustment and improving safety during production.

[0018] Furthermore, the two ends of the long shaft are secured to the support base by rotating components, allowing the long shaft to rotate flexibly while maintaining stable support.

[0019] Furthermore, the U-shaped support structure ensures the stability of the long axis when the telescopic rod moves, preventing the roller brush from swaying or shifting.

[0020] Furthermore, as a rotating component, the bearing ensures high precision and stability of the long shaft during rotation, while reducing wear on the long shaft during rotation, ensuring that the roller brush maintains constant contact pressure when cleaning glass, thereby improving the cleaning effect.

[0021] Furthermore, a sponge roller is used as the roller brush. The sponge roller has good water absorption and decontamination capabilities, which can effectively clean the glass.

[0022] Furthermore, setting the length of the long shaft to be greater than the length of the roller brush allows for greater flexibility in the installation and adjustment of the roller brush. At the same time, setting the length of the roller brush to be greater than the length of the glass to be cleaned ensures that the entire surface of the glass to be cleaned can be cleaned evenly and thoroughly when passing through the roller brush, avoiding cleaning blind spots caused by insufficient roller brush length, thereby improving cleaning quality and effect.

[0023] Furthermore, the Keyence IG-028 displacement sensor provides high-precision displacement measurement, ensuring accurate position control of the roller brush during movement. The stability of the Keyence IG-028 displacement sensor allows the device to maintain consistent measurement accuracy even during long-term use. At the same time, the fast response characteristics of the Keyence IG-028 displacement sensor can promptly capture minute movements of the roller brush, thereby achieving precise control of the cleaning process.

[0024] Furthermore, the Keyence FU-97S time sensor can accurately record the time it takes for the glass to pass through the roller brush, providing accurate timing information for the controller's decisions.

[0025] The automatic position adjustment method for cleaning glass provided by this invention can achieve precise control of the cleaning process by presetting an optimal time range T and a displacement X. When the time for the glass to be cleaned to pass through the roller brush is within the optimal time range, the roller brush remains in its original position. When the time exceeds the range, the position of the roller brush can be adjusted in real time according to the time the glass passes through the roller brush as counted by the time sensor, ensuring that the roller brush contacts the glass substrate within the optimal time range. By adjusting the position of the roller brush, the cleaning effect is ensured, improving cleaning efficiency and quality. The real-time adjustment mechanism makes the cleaning effect more stable and reliable, avoiding problems such as incomplete cleaning or damage to the glass caused by improper manual operation or inability to adjust in real time. At the same time, the rapid response and adjustment of the roller brush position is more efficient than manual adjustment, thereby improving the production efficiency of the entire production line.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. This is an explanation of the present invention and not a limitation thereof.

[0034] See Figure 1 and Figure 2 An automatic position adjustment device for cleaning glass includes a rotating assembly 9, a telescopic rod 3, a servo motor 6, a controller 7, a time sensor 5, a displacement sensor 4, and long shafts 1 arranged on both sides of the glass to be cleaned. A roller brush 2 is fitted on a long shaft 1. Rotating components 9 are connected to both ends of the long shaft 1. A servo motor 6 is connected to the outer wall of the long shaft 1 via a telescopic rod 3. The telescopic rod 3 extends and retracts in a direction perpendicular to the glass to be cleaned. The servo motor 6 is connected to a controller 7. The controller 7 is also connected to a displacement sensor 4 and a time sensor 5. The displacement sensor 4 is located at the bottom of the telescopic rod 3, and the time sensor 5 is located at the bottom of the long shaft 1.

[0035] The automatic position adjustment device for cleaning glass provided by this invention includes a rotating component, a telescopic rod, a servo motor, a controller, a time sensor, a displacement sensor, and long shafts disposed on both sides of the glass to be cleaned. The long shafts and rotating component enable the cleaning of the glass substrate. The coordination of the telescopic rod, servo motor, controller, displacement sensor, and time sensor ensures that the roller brush contacts the glass substrate at the appropriate time and position, achieving automatic adjustment of the roller brush's position. This replaces the traditional manual adjustment method, enabling real-time adjustment and improving safety during production.

[0036] Specifically, it also includes a support base 8, with both ends of the long shaft 1 respectively secured to the support base 8 via a rotating assembly 9.

[0037] The two ends of the long shaft are secured to the support base by rotating components, allowing the long shaft to rotate flexibly while maintaining stable support.

[0038] See Figure 3 Specifically, support base 8 has a U-shaped structure.

[0039] The U-shaped support base ensures the stability of the long axis when the telescopic rod moves, preventing the roller brush from swaying or shifting.

[0040] Specifically, rotating component 9 is a bearing.

[0041] As a rotating component, the bearing ensures the high precision and stability of the long shaft during rotation, while also reducing wear on the shaft and ensuring that the roller brush maintains constant contact pressure when cleaning glass, thereby improving the cleaning effect.

[0042] Specifically, roller brush 2 is a sponge roller.

[0043] Using a sponge roller as the brush, the sponge roller has good water absorption and decontamination capabilities, which can effectively clean the glass.

[0044] Specifically, the length of the long shaft 1 is greater than the length of the roller brush 2, and the length of the roller brush 2 is greater than the length of the glass to be cleaned.

[0045] Setting the length of the long shaft to be greater than the length of the roller brush allows for greater flexibility in the installation and adjustment of the roller brush. At the same time, setting the length of the roller brush to be greater than the length of the glass to be cleaned ensures that the entire surface of the glass can be cleaned evenly and thoroughly when passing through the roller brush, avoiding cleaning blind spots caused by insufficient roller brush length, thereby improving cleaning quality and effect.

[0046] Specifically, the displacement sensor 4 is a Keyence IG-028 displacement sensor.

[0047] The Keyence IG-028 displacement sensor provides high-precision displacement measurement, ensuring accurate position control of the roller brush during movement. The stability of the Keyence IG-028 displacement sensor allows the device to maintain consistent measurement accuracy even during long-term use. At the same time, the fast response characteristics of the Keyence IG-028 displacement sensor can promptly capture minute movements of the roller brush, thereby achieving precise control of the cleaning process.

[0048] Specifically, the time sensor 5 is a Keyence FU-97S time sensor.

[0049] Keyence FU-97S time sensor can accurately record the time it takes for glass to pass through the roller brush, providing accurate timing data for controller decisions.

[0050] Based on the same inventive concept, the present invention also provides an automatic positional adjustment method for cleaning glass, employing the aforementioned device, wherein the long shafts 1 disposed on both sides of the glass to be cleaned are respectively a first long shaft 1 and a second long shaft 1, the roller brush 2 sleeved on the first long shaft 1 is an upper roller brush 2, and the roller brush 2 sleeved on the second long shaft 1 is a lower roller brush 2, comprising the following steps: The optimal time range T and displacement X of the glass to be cleaned passing through the roller brush 2 are preset, where T1≤T≤T2; The time t of the glass to be cleaned passing through the roller brush 2 is counted by the time sensor 5. When t < T1, the upper and lower roller brushes 2 have not been pressed into the glass to be cleaned. The servo motor 6 is controlled to rotate forward, so that the telescopic rod 3 drives the upper and lower roller brushes 2 to move in the direction close to the glass to be cleaned. The movement distance x is sensed by the displacement sensor 4. When x = X, the servo motor 6 is turned off. When T1≤t≤T2, servo motor 6 remains off; When t > T2, the servo motor 6 is reversed, causing the telescopic rod 3 to drive the upper and lower roller brushes 2 to move away from the glass to be cleaned. The displacement sensor 4 senses the moving distance x. When x = X, the servo motor 6 is turned off. Where T1 is the preset minimum time for the glass to be cleaned to reach the cleaning standard, and T2 is the preset maximum time for the glass to be cleaned to reach the cleaning standard.

[0051] By presetting the optimal time range T and displacement X, precise control of the cleaning process can be achieved. When the time for the glass to be cleaned to pass through the roller brush is within the optimal time range, the roller brush remains in place. When the time exceeds the range, the position of the roller brush can be adjusted in real time based on the time the glass passes through the roller brush as counted by the time sensor, ensuring that the roller brush contacts the glass substrate within the optimal time range. Adjusting the position of the roller brush ensures the cleaning effect, improving cleaning efficiency and quality. The real-time adjustment mechanism makes the cleaning effect more stable and reliable, avoiding problems such as incomplete cleaning or damage to the glass caused by improper manual operation or inability to adjust in real time. At the same time, the rapid response and adjustment of the roller brush position is more efficient than manual adjustment, thereby improving the production efficiency of the entire production line.

[0052] Specifically, the optimal time T ranges from 7.8s to 8.3s, and the displacement X is 0.05mm to 0.1mm.

[0053] In a specific embodiment of the present invention, if movement is required, the upper roller can be prioritized to move in the controller via a program. Once the upper roller has moved to the set displacement, the lower roller can then be moved via the controller.

[0054] In a specific embodiment of the present invention, a support base 8 is included. A long shaft 1 is placed in the support base 8 via a bearing 9. The lower end of the support base 8 is fixed to the base with screws. The roller brush 2 is divided into upper and lower sections, which are connected and placed by the long shaft 1. Telescopic rods 3 are connected to both ends of the long shaft 1 to control the rise and fall of the roller brush. A time sensor 5 is installed below the roller brush 2, which mainly counts the time it takes for the glass to pass through. A displacement sensor 4 is installed next to the telescopic rod 3, which mainly detects the extension and retraction of the telescopic rod 3. A servo motor 6 is installed below the telescopic rod 3, which drives the telescopic rod 3 to move up and down. The time sensor 5, the displacement sensor 4, and the servo motor 6 are connected to a controller 7. The controller 7 controls the operation of the servo motor 6 by sensing the change in time through the time sensor 5, thereby driving the movement of the telescopic rod 3 and controlling the up and down movement of the roller brush.

[0055] When using this design, several pieces of glass to be cleaned are first tested. The time taken by the time sensor 5 is statistically analyzed and the average value is calculated. The standard time for the glass to be cleaned to pass through the roller brush is set. In this embodiment, the standard time is 8s. Based on the standard time, the optimal time range T is set to 7.8~8.3s and the displacement X is 0.1mm. When the glass transit time is less than 7.8 seconds, it indicates that the roller brush has not been pressed in. At this time, the controller 7 sends a signal, and the servo motor 6 starts to run in the forward direction, driving the telescopic rod 3 to move the upper roller brush downward or the lower roller brush upward. At this time, the displacement sensor 4 starts to count. When the displacement sensor 4 senses that the displacement reaches the standard of 0.1 mm set in the controller 7, the controller 7 sends a signal, and the servo motor 6 stops running. At this time, the time sensor 5 continuously counts the transit time of multiple glass sheets. When the transit time is less than 7.8 seconds, the above motion cycle continues until the time returns to 7.8~8.3 seconds, and then this motion cycle ends. Conversely, when the time sensor 5 senses that the time is greater than 8.3 seconds, the controller 7 sends a signal, and the servo motor 6 starts to run in the reverse direction, driving the telescopic rod 3 to move the upper roller brush upward or the lower roller brush downward, until the time returns to 7.8~8.3 seconds, and then this motion cycle ends. This device replaces manual adjustment, avoids safety hazards, and improves the real-time adjustment effect, ensuring the quality of the glass substrate.

[0056] Finally, it should be noted that the embodiments listed above are merely one or more specific manifestations of the technical solution of this invention. Their purpose is to clearly illustrate the concept, principle, and application of this invention through specific examples, and is by no means intended to limit the scope of protection of this invention to these specific embodiments.
