Description

Technical Field

[0001] This invention relates to the field of touch screen manufacturing technology, and more particularly to anti-glare touch screen manufacturing equipment. Background Technology

[0002] A touchscreen, also known as a touch panel or smart screen, is a sensor-based liquid crystal display device that can receive input signals from touch. When the graphical buttons on the screen are touched, the haptic feedback system drives various connected devices according to a pre-programmed program, creating vivid audio-visual effects through the liquid crystal display. Touchscreens are rapidly replacing traditional electronic screens due to their superior performance. They are very simple and direct to operate, eliminating clear age barriers; from septuagenarians and octogenarians to young children, everyone can master their use in a short time. Furthermore, they offer a timely and direct interactive experience, greatly enhancing the experience in entertainment devices and exhibitions. They give multimedia a completely new look and are highly attractive new multimedia interactive devices. Touchscreens are currently widely used in personal computers, office and government services, mobile phones, self-service equipment, retail terminals / POS machines, education and training, game consoles, industrial control, financial / ATM machines, medical equipment, aircraft flight control equipment, large-screen displays in television studios, military command systems, and urban emergency management systems. They are also widely used in many small devices such as portable personal devices (PDAs, Pocket PCs, e-books, WebPads, LCD TVs, and translation machines) and home appliances (refrigerators, washing machines, coffee makers, microwave ovens, etc.).

[0003] Currently, the production process uses chemical solutions to etch glass screens to achieve anti-glare. However, when multiple solutions are soaked sequentially, if the chemical solution on the top of the touchscreen is not cleaned thoroughly, the solutions will mix, causing changes in solution purity and resulting in poor etching effect. At the same time, when the concentration of the etching solution changes, the overall state of the device cannot be dynamically adjusted, resulting in the etching depth and flatness not meeting production requirements. Therefore, we need an anti-glare touchscreen production equipment. Summary of the Invention

[0004] The anti-glare touchscreen production equipment proposed in this invention includes a base plate, and a vertical plate is welded and fixed to the rear end of the top of the base plate. A top plate is welded and fixed to the top of the front end of the vertical plate, and a rectangular opening is opened in the middle of the top of the top plate.

[0009] Preferably, the transmission mechanism includes a rotating shaft, and a lifting rod is rotatably sleeved at the front end of the outer circumference of the rotating shaft, and a sleeve hole is opened at the top of the front end of the lifting rod, and the sleeve hole at the top of the front end of the lifting rod is sleeved on the outer circumference of the sleeve rod. A pull rod is rotatably sleeved at the rear end of the outer circumference of the rotating shaft, and a insertion hole is opened at the bottom of the front end of the pull rod.

[0010] Preferably, the pressure mechanism includes a piston cylinder, which is welded and fixed to the inner wall of a circular hole at the top of the base plate. A piston block is provided on the inner wall of the piston cylinder. Two fixing blocks are welded and fixed to the top of the piston block.

[0011] Preferably, the guiding mechanism includes a semi-circular curved plate, and a semi-circular curved plate is also welded and fixed to the top of the rear end of the second solution tank. An arc plate is welded and fixed to one side of the semi-circular curved plate of the first solution tank, and a shaking drain plate is welded and fixed to the side of the semi-circular curved plate of the first solution tank away from the arc plate.

[0014] Preferably, mounting holes are provided on both sides of the front end of the cleaning box, and rectangular blocks are detachably mounted on the inner walls of the mounting holes by bolts. Automatic steering sprayers are installed on the top and bottom of the rear ends of the two rectangular blocks, and connecting pipes are respectively connected to multiple automatic steering sprayers.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The device of the present invention is equipped with a cleaning tank, pressure pipe, connecting pipe, water inlet pipe, gear plate and other devices. In use, the rotating gear plate will use the sleeve block and the hanging rod to pull the rotating shaft to move up and down on the slide rail. The up and down movement of the rotating shaft will pull the pull rod and piston block to move inside the piston cylinder, forming an extraction process. The cleaning liquid is extracted to rinse the top and bottom of the screen, avoiding the mixing of solutions and improving the solution mixing effect.

[0017] 2. The device of this invention is equipped with a pressure spring, rollers, an automatic clamping robot, a shaking drain plate, and an irregularly protruding guide rail. Driven by a servo motor, the automatic clamping robot moves. During movement, the rollers contact the semi-circular curved plate, etc. Under the action of the pressure spring pushing the cylindrical rod, the rollers are kept in contact with the semi-circular curved plate and the shaking drain plate below. When they come into contact with the irregularly protruding guide rail, they are lifted up and then suddenly drop after passing the irregularly protruding guide rail, creating a shaking effect. This shakes off the residual solution in the first solution tank during soaking, allowing it to flow back into the first solution tank, reducing waste.

[0018] 3. This invention dynamically monitors the overall pH level inside the first solution tank by installing a pH sensor inside the tank. The detected data is fed back to the control center. The concentration of the solution can be displayed based on the data from the pH sensor, indicating the concentration change. The operating speed of the clamping component and the screen etching soaking time can be dynamically adjusted based on the specific changes. Materials can also be added to the first solution tank, and the screen can be rotated during etching to ensure the uniformity of the etching.

[0019] 4. Before etching the screen, a cleaning plate and a flatness sensor can be used to perform preliminary cleaning and flatness detection and recording, rejecting defective products. Simultaneously, the rotation of the clamping rod enables double-sided cleaning and inspection of the screen. After rinsing, the cleaning plate thoroughly cleans the entire screen and all four corners. After cleaning, the flatness of the etched surface is compared using the flatness sensor. The etching depth can be determined based on the extension of the telescopic rod. Through multiple comparisons and calculations, the correlation between solution concentration, soaking time, etching depth, and etching flatness can be established within the existing environment and operating procedures. If the etching effect is unsatisfactory, the solution concentration and soaking time can be adjusted accordingly for the next screen immersion, enabling the device to continuously and dynamically change various parameters such as solution concentration and soaking time during screen etching.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figure 1-10 The anti-glare touchscreen production equipment includes a base plate 1, with a vertical plate 8 welded and fixed to the rear end of the top of the base plate 1. A top plate 13 is welded and fixed to the top of the front end of the vertical plate 8, and a rectangular opening is formed in the middle of the top of the top plate 13. Sliding groove rods 35 are detachably installed at the front and rear ends of the bottom of the top plate 13 via bolts. Two sliding blocks 40 are slidably installed at the bottom of each of the two sliding groove rods 35. A sliding plate 34 is detachably installed at the bottom of the multiple sliding blocks 40 via bolts, and a moving mechanism is provided in the middle of the bottom of the sliding plate 34. A slide rail 26 is welded and fixed to the front end of the vertical plate 8 away from the sliding plate 34, and a transmission mechanism is slidably installed at the front end of the slide rail 26. A circular hole is formed at the rear end of the top of the base plate 1 near the slide rail 26, and a pressure mechanism is welded and fixed to the inner wall of the circular hole. A first solution tank 3 is welded to the front end of one side of the slide rail 26. The first solution tank 3 contains the solution required for the initial soaking of the screen. A cleaning tank 6 is welded to the middle of the front end of the top of the base plate 1. A second solution tank 7 is welded to the front end of the top of the base plate 1 away from the first solution tank 3. The second solution tank 7 contains the solution required for the secondary soaking of the screen. A guide mechanism is welded to the top of the rear end of the first solution tank 3. The roller 21 of the moving mechanism moves on the guide mechanism. The shape of the guide mechanism will drive the moving mechanism to move and adjust upward or downward at a designated position. When descending, the automatic clamping robot 14 holding the screen will drive the screen to descend and enter the tank for soaking or cleaning. Base blocks 2 are welded to both sides of the bottom of the base plate 1.

[0033] Reference Figure 1 , Figure 8 , Figure 9 The moving mechanism includes a sleeve 12, which is fixed to the middle of the bottom of the sliding plate 34. A pressure spring 44 is provided on the inner wall of the sleeve 12. A cylindrical rod 18 is inserted into the bottom of the inner circumference of the sleeve 12. The pressure spring 44 will always push the cylindrical rod 18 down. A mounting block 28 is welded to the bottom of the cylindrical rod 18. An automatic gripping robot 14 is detachably installed on the bottom of the mounting block 28 by bolts. When in use, the automatic gripping robot 14 will automatically grip the touch screen that needs to be soaked in the solution.

[0034] Reference Figure 8 , Figure 9A hanging plate 19 is welded and fixed to the rear end of the mounting block 28, and a mounting shaft 20 is rotatably mounted at the middle of the bottom of the rear end of the hanging plate 19. A roller 21 is rotatably mounted on the outer circumference of the mounting shaft 20. The roller 21 is mounted at the rear end of the mounting block 28 via the hanging plate 19, and the lowest point of the roller 21 is lower than the lowest point of the automatic gripping robot 14. Under the action of the downward spring 44, the cylindrical rod 18 will be pushed down. In the initial position, the automatic gripping robot 14 contacts the substrate 15 and clamps its touch screen. After moving to a certain position, the roller 21 will contact the half-mounted substrate 15. The arc-shaped curved plate 27 and the roller 21 will descend under the push of the compression spring 44. When moving on the semi-circular curved plate 27, they will move in the concave part of its curve, thereby driving the front automatic gripping robot 14 and the gripped touch screen to move in an arc-shaped running trajectory, thus entering the first solution tank 3. When the servo motor 11 stops, it will keep the automatic gripping robot 14 and the gripped touch screen inside the first solution tank 3 for immersion. The rear end of the sliding plate 34 is welded and fixed with a toothed rod 33, and the top of the toothed rod 33 is welded with several toothed blocks 36.

[0035] The lower end of the automatic gripping robot 14 is slidably mounted with a gripper 48. The inner side of the gripper 48 is provided with a rotatable gripping rod 49. The middle part of the gripping rod 49 is rotatably connected to the gripper 48. The lower middle part of the automatic gripping robot 14 is provided with a reciprocating telescopic rod 46. The lower end of the telescopic rod 46 is fixedly connected with a cleaning plate 47. Flatness sensors are provided on both sides of the cleaning plate 47.

[0036] The two grippers 48 at the lower end of the automatic gripping robot 14 can move horizontally inward or outward simultaneously via cylinders, threaded rods, etc. (the movement of the grippers 48 is not limited here), thereby driving the gripping rod 49 to move inward and outward, enabling the gripping of screens of different widths. The screen can rotate synchronously with the rotation of the gripping rod 49, and there is no interference with the cleaning plate 47 during the screen rotation. After the screen is gripped, the cleaning plate 47 moves downward as the telescopic rod 46 extends. Then, the reciprocating movement of the telescopic rod 46 can drive the cleaning plate 47 to pre-clean the surface of the screen. The reciprocating movement of the telescopic rod 46 is not limited and can be achieved by a cylinder or threaded rod, etc., which will not be elaborated here. The upper surface is wiped. The cleaning plate 47 can be rectangular or other polygonal, depending on the specific requirements. However, the cleaning plate 47 must have at least one acute angle or right angle to ensure that the four corners of the screen are completely wiped during the reciprocating wiping process, thus ensuring the wiping effect. At the same time, the flatness of the screen before etching is detected by a flatness sensor. After etching is completed, the effect of the entire etching process is evaluated by comparing the data before and after etching.

[0037] When the automatic gripper 14 moves the screen to be immersed and etched in the first solution tank 3, the gripping rod 49 can move the screen to rotate in the first solution tank 3. While rotating, the screen can effectively reduce the occurrence of side etching and increase the consistency of the etching effect. At the same time, when the screen rotates in the first solution tank 3, the solution inside can also be stirred and mixed to ensure that the acidity of the liquid inside the first solution tank 3 is uniform and consistent, further enhancing the etching effect.

[0038] The concentration of the liquid inside the first solution tank 3 is difficult to control precisely, which makes it difficult to control the etching effect. Therefore, it is necessary to use multiple pH sensors to monitor the pH inside the first solution tank 3 in real time. Multiple pH sensors can detect the pH of the solution inside the first solution tank 3 in a coordinated manner. If the error between multiple pH sensors is large, the machine should be stopped immediately and the inside of the first solution tank 3 should be checked. The device can only operate normally when the error between multiple pH sensors is within the normal range.

[0039] During the screen etching process, acidic or alkaline etching solutions can be used to etch the screen. This article first analyzes the acidic etching solution. During the screen etching process, the glass at the top of the screen will react with the etching solution. According to the reaction formula, while consuming hydrofluoric acid, water will also be produced during the reaction, which will further dilute the etching solution in the first solution tank 3, resulting in a decrease in concentration.

[0040] When the acidity inside the first solution tank 3 decreases, it indicates a reduction in the concentration of the etching solution. This causes a decrease in the etching rate of the screen during immersion in the first solution tank 3. Accordingly, the automatic gripping robot 14 is adjusted to extend the immersion time of the screen in the first solution tank 3, and the screen's rotation speed is also reduced to ensure effective etching. Simultaneously, before the next screen etching, the feeding valve on the side of the first solution tank 3 opens, adding etching solution to increase the concentration inside the first solution tank 3. The corresponding data detected by the pH sensor rises, and the immersion time of the screen is further dynamically adjusted accordingly. If the feeding valve malfunctions, multiple pH sensors will detect changes in solution concentration, and the control center will extend or reduce the immersion time to prevent excessively high concentrations from causing an excessively fast etching rate, damaging the screen, and resulting in defective products.

[0041] Reference Figure 2 , Figure 3Two bases 16 are welded and fixed to the rear end of the top plate 13 near the slide rail 26. The top of the two bases 16 is detachably mounted with the same servo motor 11 by bolts. A gear plate 10 is welded and fixed to the front end of the output shaft of the servo motor 11. A sleeve rod 38 is welded and fixed to the front end of the gear plate 10 at a position off-center. The gear plate 10 meshes with the tooth block 36 below. The gear plate 10 is relatively large and passes through the rectangular opening in the top plate 13. When the servo motor 11 is running, it will drive the gear plate 10 to rotate. When rotating, it will mesh with the tooth block 36 below. When rotating, it will drive the tooth block 36 and the tooth rod 33 on which it is mounted to move.

[0042] Reference Figure 4 , Figure 6 , Figure 7 , Figure 8 The transmission mechanism includes a rotating shaft 29, which is slidably mounted on a slide rail 26. Under the drive of an external force, the rotating shaft 29 will move vertically up or down on the slide rail 26. A hanging rod 37 is rotatably sleeved at the front end of the outer circumference of the rotating shaft 29, and a sleeve hole is opened at the top of the front end of the hanging rod 37. The sleeve hole at the top of the front end of the hanging rod 37 is sleeved on the outer circumference of the sleeve rod 38. A pull rod 25 is rotatably sleeved at the rear end of the outer circumference of the rotating shaft 29, and a insertion hole is opened at the bottom of the front end of the pull rod 25. The top of the hanging rod 37 is sleeved on the sleeve rod 38. When the sleeve rod 38 moves in a circular trajectory with the gear plate 10, it will pull the upper end of the hanging rod 37 to move in a circular trajectory. However, the lower end of the hanging rod 37 is sleeved on the outer circumference of the rotating shaft 29, and the angle can be changed. This will pull the rotating shaft 29 to move vertically on the slide rail 26. Under the limitation of the slide rail 26, it can only move vertically up and down.

[0043] Reference Figure 4 , Figure 8The pressure mechanism includes a piston cylinder 9, which is welded and fixed to the inner wall of a circular hole at the top of the base plate 1. A piston block 42 is provided on the inner wall of the piston cylinder 9. Two fixing blocks 43 are welded and fixed to the top of the piston block 42, and the same rotating shaft 41 is welded and fixed to the middle of one side between the two fixing blocks 43. The rotating shaft 41 is inserted into the insertion hole of the pull rod 25. The pull rod 25 is rotatably mounted on the outer wall of the rotating shaft 41. The top of the pull rod 25 is also rotatably sleeved on the outer wall of the rotating shaft 29. When the rotating shaft 29 moves vertically up and down on the slide rail 26, it will pull the piston block 42 to move up and down inside the piston cylinder 9. The piston block 42 is made of rubber. Made of rubber, it fits the inner wall of the piston cylinder 9, forming a suction and squeezing function when moving. During operation, the piston cylinder 9 is connected to the bottom of the connecting pipe 5 and the water inlet pipe 45. The front end of the bottom of the piston cylinder 9 is connected to the connecting pipe 5, and the rear end of the bottom of the piston cylinder 9 is connected to the water inlet pipe 45. Both the water inlet pipe 45 and the connecting pipe 5 are equipped with one-way valves. The water inlet pipe 45 can only inject into the piston cylinder 9 through the one-way valve, and the connecting pipe 5 can only discharge the cleaning fluid inside the piston cylinder 9 through the one-way valve. Under the movement of the rubber piston block 42 inside the piston cylinder 9, it is drawn in from the water inlet pipe 45 and then discharged from the cleaning fluid injection connecting pipe 5 through squeezing.

[0044] Reference Figure 3 , Figure 4 , Figure 8The guiding mechanism includes a semi-circular curved plate 27, and the top of the rear end of the second solution tank 7 is also welded with a semi-circular curved plate 27. When the roller 21 enters the semi-circular curved plate 27 at the rear end of the first solution tank 3, the automatic gripping robot 14 at the front end and the touch screen it grips will enter the interior of the first solution tank 3 for immersion. An arc plate 22 is welded to one side of the semi-circular curved plate 27 on the first solution tank 3, and a shaking drain plate 24 is welded to the side of the semi-circular curved plate 27 away from the arc plate 22. Multiple irregularly protruding guide rails 23 are welded to the top of the shaking drain plate 24. When the gripper 48 moves the screen upward, there may be residual liquid. At this time, the screen is in a horizontal state. Then, the gripping rod 49 is rotated to make the screen tilted. This facilitates the downward flow of residual liquid. Simultaneously, when the servo motor 11 drives the rack 33 and the automatic clamping robot 14 below to move, it first moves on the semi-circular curved plate 27 at the rear end of the first solution tank 3. When it moves to the top of the shaking drain plate 24, it is lifted by the irregular protruding guide rail 23 installed on the shaking drain plate 24. When it passes the irregular protruding guide rail 23, the downward pressure spring 44, due to the force of constantly pushing the cylindrical rod 18 downward, will cause its roller 21 to suddenly drop and contact the shaking drain plate 24, resulting in up-and-down vibrations of different amplitudes. This causes the automatic clamping robot 14 and the clamped touch screen to shake, shaking off the solution carried during immersion in the first solution tank 3. After the residual liquid on the screen is completely drained, the telescopic lever returns to a horizontal state, causing the clamped screen to become horizontal, and then it moves towards the cleaning tank 6.

[0045] Reference Figure 4 , Figure 8 A horizontal plate 32 is welded and fixed to the side of the shaking drain plate 24 away from the arc plate 22. When the roller 21 continuously rolls onto the horizontal plate 32, the automatic gripping robot 14 and the gripped touch screen will enter the interior of the cleaning tank 6 and move for a long time. During the movement inside the cleaning tank 6, it will be rinsed. The horizontal plate 32 is welded and fixed to the rear end of the cleaning tank 6. A suspension plate 31 is welded and fixed to the side of the horizontal plate 32 away from the arc plate 22. The other side of the suspension plate 31 is fixed to one side of the semi-circular curved plate 27. The roller 21 passes through the horizontal plate 32 and enters the suspension plate 31, forming an upward movement, which drives the automatic gripping robot 14 and the gripped touch screen to move out of the interior of the cleaning tank 6. When it moves onto the suspension plate 31, the servo motor 11 stops running, so that the automatic gripping robot 14 and the gripped touch screen stop moving, and the cleaning liquid on the surface of the touch screen drips off.

[0046] After cleaning, residual cleaning solution may remain. If this solution isn't completely removed, it will affect the next step. At this point, the screen is horizontal. The telescopic rod 46 extends downwards, causing the fixedly connected cleaning plate 47 to contact the upper surface of the screen. The depth of etching at the top of the screen can be determined based on the extension and retraction of the telescopic rod 46. As the telescopic rod 46 moves back and forth, the cleaning plate 47 moves back and forth on the upper surface of the screen to wipe away any remaining solution. The cleaning plate 47 has at least one acute angle to ensure proper cleaning. During the reciprocating wiping process, the cleaning plate 47 can ensure that all four corners of the screen are completely wiped, ensuring the wiping effect. The flatness detectors on both sides of the cleaning plate 47 can detect the flatness of the cleaned screen end face, and then the flatness data is recorded through the control center. After the upper end face is cleaned and inspected, the telescopic rod 46 drives the cleaning plate 47 to move upward, and then the clamping rod 49 rotates to flip the lower end face of the screen up. The above operation is repeated to detect the etching depth of the lower end face of the screen, and at the same time, to perform comprehensive cleaning and lower end face flatness detection.

[0047] Furthermore, the extension and retraction of the telescopic rod 46 and the measurement results from the flatness sensor can be fed back to the control center. This allows us to determine the etching effect under the current solution concentration and immersion time during the etching process. Through multiple comparative calculations, we can determine the correlation between solution concentration, immersion time, etching depth, and etching flatness in the existing environment and operating procedures. If the etching effect is not up to standard, we can adjust the solution concentration and immersion time for the next screen immersion. This enables the device to continuously and dynamically change various parameters such as solution concentration and immersion time during screen etching to ensure that the etching effect meets the expected results.

[0048] Reference Figure 1 , Figure 2 , Figure 5 A base plate 15 is welded and fixed to the top of the first solution tank 3 on the side away from the cleaning tank 6, and a guide plate 4 is welded and fixed to the top of the first solution tank 3 on the side away from the base plate 15. When the roller 21 passes through the irregular protruding guide rail 23 on the shaking drain plate 24, the solution carried in the first solution tank 3 will be shaken off and drip onto the guide plate 4. Due to the tilt of the guide plate 4, it will flow back into the interior of the first solution tank 3. The shaking drain plate 24 is welded and fixed to the rear end of the guide plate 4, and the other side of the guide plate 4 is fixed to one side of the top of the cleaning tank 6. A rectangular hole is opened on the top of the side of the cleaning tank 6 near the second solution tank 7, and a collection inclined plate 39 is welded and fixed to the inner wall of the rectangular hole. When the roller 21 stops on the suspension plate 31, the cleaning liquid carried out of the cleaning tank 6 by the automatic gripping robot 14 during the cleaning will drip onto the collection inclined plate 39 and will also flow into the interior of the cleaning tank 6 for unified treatment.

[0049] Reference Figure 4 , Figure 6 , Figure 7 The front end of the cleaning tank 6 has mounting holes on both sides, and rectangular blocks 17 are detachably installed on the inner wall of the mounting holes by bolts. Automatic steering sprayers 30 are installed on the top and bottom of the rear ends of the two rectangular blocks 17. The connecting pipes 5 are connected to multiple automatic steering sprayers 30. The automatic steering sprayers 30 are connected to the connecting pipes 5 with internal one-way valves. When the piston cylinder 9 is pulled out, the automatic steering sprayers 30 will spray cleaning fluid on its top and bottom respectively to achieve a cleaning effect.

[0050] In use, the servo motor 11 first runs, driving the gear plate 10 to rotate. During rotation, it meshes with the lower gear block 36, causing the gear block 36 and the mounted gear rack 33 to move. The gear rack 33 and the sliding plate 34 both move below the sliding groove rod 35, thus moving the automatic gripping robot 14 and cylindrical rod 18 at the bottom of the sliding plate 34. The automatic gripping robot 14 contacts the substrate 15, clamping its touchscreen. The two jaws 48 at the lower end of the automatic gripping robot 14 can move horizontally inward or outward simultaneously, thereby driving the clamping rod 49 to move inward and outward, enabling clamping of screens of different widths. It can rotate synchronously with the rotation of the clamping rod 49, and will not interfere with the automatic clamping robot 14 during the screen rotation. After the screen is clamped, the cleaning plate 47 moves downward with the extension of the telescopic rod 46. Then, the reciprocating movement of the telescopic rod 46 can drive the cleaning plate 47 to pre-clean the surface of the screen and wipe the upper surface. The cleaning plate 47 has at least one acute angle or right angle, which can ensure that the four corners of the screen are completely wiped during the reciprocating wiping process, ensuring the wiping effect. At the same time, the flatness of the screen before etching is detected by the flatness sensor.

[0051] After moving to a certain position, the roller 21 will contact the semi-circular curved plate 27. The roller 21 will descend under the push of the downward spring 44. When moving on the semi-circular curved plate 27, it will move in the concave part of its curve, thereby driving the front-end automatic gripping robot 14 and the gripped touch screen to move in an arc-shaped running trajectory, thus entering the first solution tank 3. When the servo motor 11 stops, it will keep the automatic gripping robot 14 and the gripped touch screen inside the first solution tank 3 for immersion. When the automatic gripping robot 14 drives the screen to immerse and etch in the first solution tank 3, the gripping rod 49 can drive the screen to rotate in the first solution tank 3. At the same time, the rotation can effectively reduce the occurrence of side etching of the screen and increase the consistency of the etching effect. At the same time, when the screen rotates in the first solution tank 3, it can also stir and mix the solution inside, ensuring that the acidity of the liquid inside the first solution tank 3 is uniform and further enhancing the etching effect.

[0052] During the screen etching process, acidic or alkaline etching solutions can be used to etch the screen. This article first analyzes the acidic etching solution. During the screen etching process, the glass at the top of the screen will react with the etching solution. According to the reaction formula, while consuming hydrofluoric acid, water will also be produced during the reaction, which will further dilute the etching solution in the first solution tank 3.

[0053] When the acidity inside the first solution tank 3 decreases, it indicates a reduction in the concentration of the etching solution. This causes a decrease in the etching rate during screen immersion in the first solution tank 3. Accordingly, the automatic gripper 14 extends the immersion time of the screen in the first solution tank 3. Simultaneously, before the next screen etching, the feeding valve on the side of the first solution tank 3 opens, adding etching solution to increase the concentration inside the first solution tank 3. The corresponding data detected by the pH sensor rises, and the immersion time is dynamically adjusted accordingly. If the feeding valve malfunctions, multiple pH sensors will detect changes in solution concentration, and the control center will extend or reduce the immersion time to prevent excessively high concentrations from causing an excessively fast etching rate, damaging the screen, and resulting in defective products.

[0054] When the gripper 48 moves the screen upward, there may be residual liquid. At this time, the screen is in a horizontal position. Then, the gripping rod 49 is rotated to tilt the screen, which is more conducive to the downward flow of residual liquid. At the same time, when the servo motor 11 moves the rack 33 and the automatic gripping robot 14 below, it first moves on the semi-circular curved plate 27 at the rear end of the first solution tank 3. When it moves to the top of the shaking drain plate 24, it is lifted by the irregular protruding guide rail 23 installed on the shaking drain plate 24. After passing the irregular protruding guide rail 23, it moves upward. At time 3, the downward spring 44, due to the force that constantly pushes the cylindrical rod 18 downward, will cause its roller 21 to suddenly drop and contact the vibrating drain plate 24, resulting in up-and-down vibrations of varying amplitudes. This will cause the automatic gripping robot 14 and the gripped touch screen to vibrate, shaking off the solution carried during immersion in the first solution tank 3. After passing through the irregular protruding guide rail 23 on the vibrating drain plate 24, the solution carried in the first solution tank 3 will be shaken off and drip onto the guide plate 4. Due to the tilt of the guide plate 4, it will flow back into the interior of the first solution tank 3.

[0055] Once the residual liquid on the screen is completely removed, the telescopic lever returns to a horizontal position, causing the clamped screen to become horizontal as well. It then moves towards the cleaning tank 6. During this continued movement, it passes through the horizontal plate 32 and enters the cleaning tank 6. Simultaneously, the servo motor 11 drives the sleeve rod 38 in a circular motion along the gear plate 10, pulling the upper end of the hanging rod 37 in a circular motion. However, the lower end of the hanging rod 37 is fitted onto the outer circumference of the rotating shaft 29, allowing for angle changes. This pulls the rotating shaft 29 vertically along the slide rail 26. As the rotating shaft 29 moves vertically up and down along the slide rail 26, it pulls the piston block 42 inside the piston cylinder 9. The piston moves up and down, and the piston block 42 is made of rubber, which fits the inner wall of the piston cylinder 9. When moving, it forms a function of extraction and squeezing. The inlet pipe 45 and the connecting pipe 5 are both equipped with one-way valves. The inlet pipe 45 can only inject into the piston cylinder 9 through the one-way valve, and the connecting pipe 5 can only discharge the cleaning fluid inside the piston cylinder 9 through the one-way valve. Under the movement of the piston block 42 inside the piston cylinder 9, the cleaning fluid is drawn in from the inlet pipe 45 and discharged from the connecting pipe 5 through squeezing. The automatic directional sprayer 30 is connected to the connecting pipe 5 with the one-way valve inside. When the piston cylinder 9 is extracted, the automatic directional sprayer 30 will spray cleaning fluid on its top and bottom respectively to form a cleaning effect.

[0056] After cleaning, roller 21 passes through horizontal plate 32 and enters suspended plate 31, forming an upward movement. This causes the automatic gripping robot 14 and the gripped touchscreen to move out of the cleaning tank 6. When it reaches suspended plate 31, servo motor 11 stops running, stopping the automatic gripping robot 14 and the gripped touchscreen, allowing the cleaning fluid on the touchscreen surface to drip off. Even after cleaning, there may be residual cleaning fluid when roller 21 rests on suspended plate 31. If the fluid is not completely removed, it will affect the processing effect in the next step. At this point, the screen is horizontal. Then, telescopic rod 46 extends downward, causing the fixedly connected cleaning plate 47 to contact the upper surface of the screen. The etching depth at the upper surface of the screen can be determined based on the extension and retraction of telescopic rod 46. As the telescopic rod 46 moves back and forth, it drives the cleaning plate 47 to move back and forth at the top of the screen to wipe away residual liquid. The cleaning plate 47 has at least one acute angle or right angle, which ensures that the four corners of the screen are completely wiped during the back and forth wiping process, ensuring the wiping effect. The flatness detectors on both sides of the cleaning plate 47 can detect the flatness of the cleaned screen end face, and then the flatness data is recorded by the control center. After the top end face is cleaned and inspected, the telescopic rod 46 drives the cleaning plate 47 to move upward, and then the clamping rod 49 rotates to flip the bottom end face of the screen up. The above operation is repeated to detect the etching depth of the bottom end face of the screen, and at the same time, to perform comprehensive cleaning and detect the flatness of the top and bottom end faces.

[0057] Before screen etching, the flatness and thickness of the screen before etching can be determined by the flatness sensor and the extension of the telescopic rod 46. At the same time, based on the acidity and alkalinity detected by the acid-base sensor inside the first solution tank 3, the immersion time of the automatic gripper 14 in the first solution tank 3 and the flipping speed of the screen in the first solution tank 3 can be controlled, thereby ensuring the etching efficiency of the screen in the first solution tank 3. During cleaning in the cleaning tank 6, the flatness and thickness of the screen after etching can be determined by the flatness sensor and the extension of the telescopic rod 46. Based on the data obtained during the cleaning process, the immersion time and flipping efficiency of the automatic gripper 14 carrying the screen in the first solution tank 3 can be adjusted to ensure that the screen has the same performance after etching.

[0058] When the pH sensor detects that the acidity inside the first solution tank 3 is strong, the automatic gripping robot 14 is controlled to shorten the immersion time inside the first solution tank 3 and increase the flipping speed. The pH sensor is used to detect the change in the pH of the solution. At the same time, when the automatic gripping robot 14 is cleaning in the cleaning tank 6, the flatness sensor and the extension of the telescopic rod 46 are used to detect the depth of screen etching and the flatness after etching. When the depth is consistent and the flatness difference is small, it means that the screen etching is completed and meets the etching standard. At this time, it is only necessary to control the immersion time of the automatic gripping robot 14 and the screen flipping speed according to the change in the pH of the solution.

[0059] When the pH sensor detects that the acidity in the first solution tank 3 has decreased, the soaking time of the automatic gripper 14 is increased and the flipping speed is slowed down. The pH sensor is used to detect the change in the pH of the solution. At the same time, when the automatic gripper 14 is cleaning in the cleaning tank 6, the flatness sensor and the extension of the telescopic rod 46 detect the etching depth and the flatness after etching. When the etching depth is consistent and the flatness difference is small, it indicates that the etching of the screen is complete and meets the various etching indicators.

[0060] When the pH sensor detects a decrease in acidity in the first solution tank 3, the soaking time of the automatic gripper 14 is increased and the rotation speed is slowed down. When the flatness sensor and the telescopic rod 46 detect that the etching depth is inconsistent and the flatness difference is large, it means that the etching effect is not good. At this time, the automatic gripper 14 is controlled to move in the opposite direction, driving the screen to move and soak it in the first solution tank 3 again for a certain period of time. The automatic gripper 14 can drive the screen on the side with deeper etching to rotate upward, placing the side with shallower etching on the liquid surface, etching one side of the screen, and then cleaning the screen again. After cleaning, the depth and flatness are detected on both sides to ensure that the etching depth on both ends of the screen is the same and the flatness difference is small, which meets the requirements of industrial production.

[0061] When the touch screen held by the automatic gripping robot 14 is cleaned, the cleaning fluid carried out of the cleaning tank 6 will drip onto the collecting inclined plate 39 and flow into the cleaning tank 6 for unified treatment. Then, the roller 21, driven by the servo motor 11, enters the semi-circular curved plate 27 at the rear end of the second solution tank 7. The principle is the same as that of the semi-circular curved plate 27 at the rear end of the first solution tank 3. The touch screen held by the automatic gripping robot 14 is carried into the interior of the second solution tank 7 for immersion in another solution.

[0062] Furthermore, the extension and retraction of the telescopic rod 46 and the measurement results from the flatness sensor can be fed back to the control center. This allows us to determine the etching effect under the current solution concentration and immersion time during the etching process. Through multiple comparative calculations, we can determine the correlation between solution concentration, immersion time, etching depth, and etching flatness in the existing environment and operating procedures. If the etching effect is not up to standard, we can adjust the solution concentration and immersion time for the next screen immersion. This enables the device to continuously and dynamically change various parameters such as solution concentration and immersion time during screen etching to ensure that the etching effect meets the expected results.
