Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to an automatic laser etching device for ITO film on electronic glass and its usage method. Background Technology

[0002] ITO glass refers to ultra-thin glass in the ITO industry, with a thickness of only 0.3-0.5mm. It is a functional material made by coating a layer of transparent indium tin oxide film on the surface of ordinary glass. It is widely used in touch screens, displays, solar cells and electronic devices. Laser etching is a precision processing technology that uses a high-energy laser beam to locally heat, vaporize or melt the surface of a material to achieve engraving, cutting or etching. It is widely used in electronics, semiconductors, medical and industrial manufacturing.

[0003] ITO glass laser etching machines are specialized equipment for high-precision etching of ITO glass surfaces. However, existing ITO electronic glass laser etching equipment relies on manual processing, which results in problems such as insufficient dimensional positioning accuracy, slow processing speed, small processing size, and insufficient efficiency in mass production.

[0004] Because ultra-thin glass is only 0.3-0.5mm thick, it is prone to breakage during handling and processing due to improper handling. It also emits smoke and pollutants, posing safety hazards. Therefore, technological improvements are urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic laser etching device for ITO film of electronic glass and its usage method, so as to solve the problem of small processing size and low production efficiency of ultra-thin glass mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic laser etching device for ITO film on electronic glass, comprising a cabinet assembly, a cover assembly fixedly mounted on the outer surface of the cabinet assembly, the cover assembly being composed of sheet metal welding, and a display, a pneumatic door, and a button mounted on one end side surface of the cover assembly; the cabinet assembly using square tubing welded as a frame; a loading rack fixedly mounted on one end side surface of the cabinet assembly, and a rotating roller provided between the loading rack and the cabinet assembly; a transmission latching mechanism provided between the loading rack and the rotating roller, and the transmission latching mechanism including: a first helical gear set; The first helical gear set is fixedly installed on the outer surface of the cabinet assembly and the loading rack, respectively. Rotating rollers are uniformly fixedly arranged on the outer surface of the first helical gear set, and the rotating rollers are cylinders made of UPE material. A first servo motor is fixedly installed on the side surface of the first helical gear set, and the output end of the first servo motor is connected to the rotating part of the first helical gear set. Guide wheels are fixedly installed on the outer surface of the cabinet assembly and the loading rack, and the guide wheels are located inside the first helical gear set. A blocking component is fixedly installed on the outer surface of the cabinet assembly, and the blocking component is located on one side of the first helical gear set.

[0007] Preferably, an air source triplet and a fan are fixedly installed on the outer surface of the cabinet assembly, and a water chiller is provided at one end of the cabinet assembly.

[0008] By adopting the above technical solution, the internal temperature of the cabinet components can be controlled in real time through the water chiller, the laser can be cooled, the pneumatic components inside the equipment can be lubricated through the air source triplet to improve their service life, and the smoke and dust generated during coding can be purified and discharged.

[0009] Preferably, a grating is installed inside the housing assembly, and a three-color light is fixedly installed on the outer surface of one end of the housing assembly. A cabinet is provided on the side of the cabinet assembly near the water chiller, and the cabinet is connected to the cables of the cabinet assembly.

[0010] Using the above technical solution, the equipment can be controlled and operated through the display, buttons and other devices set on the outer surface of the housing assembly. The tri-color lights allow workers to clearly understand the working status of the equipment, and the safety light curtains can enhance the safety protection of production personnel.

[0011] Preferably, equal-height blocks are uniformly fixedly installed on the outer surface of the cabinet assembly near the first helical gear set. A support plate is fixedly installed on the outer surface of the cabinet assembly, and the support plate is located on both sides of the equal-height blocks. A sliding lifting mechanism is provided between the equal-height blocks and the cabinet assembly. The sliding lifting mechanism includes a lifting cylinder, which is fixedly installed on the outer surfaces of both ends of the cabinet assembly. A linear lifting guide rail is fixedly installed on the outer surface of the cabinet assembly. A line connecting plate is fixedly installed at the output end of the lifting cylinder. A second helical gear assembly is fixedly installed on the outer surface of the line connecting plate. A second servo motor is fixedly installed on the side surface of the second helical gear assembly, and the output end of the second servo motor meshes with the second helical gear assembly. The linear lifting guide rail is connected to the line connecting plate. Another blocking component is fixedly installed at the end of the cabinet assembly away from the loading rack.

[0012] By adopting the above technical solution, when the ultra-thin glass enters the processing area, the lifting cylinder can drive the line connecting plate to descend, allowing the second helical gear assembly to descend along with it. This allows the ultra-thin glass to be processed to be smoothly placed on the level block and support plate, preventing deformation of the ultra-thin glass during processing and reducing the chance of breakage, thus facilitating subsequent etching processing.

[0013] Preferably, the cabinet assembly and the equalization block are fixedly mounted on both sides with linear rails, and a sliding adjustment mechanism is provided between the linear rails. The sliding adjustment mechanism includes: a leveling guide plate, which is slidably mounted on the outer surface of the linear rails; a geared servo motor is fixedly mounted on the outer surface of the cabinet assembly near the linear rails; a synchronous idler wheel assembly is fixedly mounted on the outer surface of the cabinet assembly away from the geared servo motor; the leveling guide plate is connected to the outer surface of the synchronous idler wheel assembly, and the synchronous idler wheel assembly is connected to the geared servo motor; a first photoelectric sensor is fixedly mounted on the outer surface of the cabinet assembly, and the first photoelectric sensor is located between the linear rails.

[0014] By adopting the above technical solution, the synchronous idler wheel assembly can reduce costs while ensuring stable operation, low noise and high precision. It can reduce noise and increase service life. Furthermore, the rotation of the geared servo motor can drive the regular guide plate to move, so that the regular guide plate can clamp and coarsely position the ultra-thin glass, allowing ultra-thin glass of different sizes to be aligned and clamped.

[0015] Preferably, a mobile platform assembly is fixedly installed on the outer surface of the cabinet assembly, and the mobile platform assembly includes: a first linear guide rail assembly, the first linear guide rail assembly being fixedly installed on the outer end surface of the cabinet assembly, a second linear guide rail assembly being slidably installed on the outer surface of the first linear guide rail assembly, and a slide table assembly being slidably installed on the outer surface of the second linear guide rail assembly, the second linear guide rail assembly and the first linear guide rail assembly being powered by linear motors, and the first linear guide rail assembly adopting a gantry dual-drive mode.

[0016] Using the above technical solution, the first linear guide rail assembly moves along the X-axis and the second linear guide rail assembly moves along the Y-axis. The first linear guide rail assembly on the X-axis adopts a gantry dual-drive mode, which can move simultaneously and has high positioning accuracy, with even higher accuracy when a single module is repeatedly positioned.

[0017] Preferably, a grating ruler is fixedly installed on the outer surface of the first linear guide assembly and the second linear guide assembly, and a second photoelectric sensor is fixedly installed on the outer surface of the second linear guide assembly and the first linear guide assembly.

[0018] By adopting the above technical solution, the positional accuracy of the first linear guide assembly and the second linear guide assembly can be improved and the error can be compensated and corrected by using a grating ruler, and the first linear guide assembly and the second linear guide assembly can be limited by using a second photoelectric sensor.

[0019] Preferably, the outer surface of the slide assembly is provided with an optical etching mechanism, and the optical etching mechanism includes: a laser, the laser being fixedly installed on the outer surface of the slide assembly, a galvanometer being fixedly installed on one side surface of the slide assembly, a CCD assembly being fixedly installed on the outer surface of the slide assembly, a height sensor being fixedly installed on the side surface of the slide assembly, a two-dimensional reflector frame being provided between the galvanometer and the laser, and the laser being a 10W picosecond ultraviolet laser.

[0020] Using the above technical solution, the edge of ultra-thin glass can be positioned by CCD components and height sensors. It has the advantages of ultra-high-speed sampling, stable detection, and the ability to measure large workpieces, achieving accurate and rapid positioning. The ultraviolet 10W picosecond laser used in this application has advantages such as short wavelength, high precision, high energy density, and low thermal impact. Through an imported high-speed galvanometer, the laser and galvanometer can be used to etch the middle layer of the ultra-thin glass, completing high-precision etching, reducing manual intervention, improving work efficiency and product quality, maintaining high precision and high stability during the processing, avoiding product damage, and having a wide range of applications.

[0021] A method for using an automated laser etching apparatus for ITO film on electronic glass, comprising the following steps:

[0022] S1: Workers need to place the ultra-thin glass to be etched on the top of the loading rack. The rotation of the first servo motor drives the first helical gear set to rotate, so that the rotating roller can rotate along with it, moving the ultra-thin glass and guiding it through the guide wheel, so that the ultra-thin glass to be processed can be stored inside the cabinet assembly, and the excess ultra-thin glass can be blocked by the lifting of the blocking assembly.

[0023] S2: After the ultra-thin glass in S1 enters the processing and etching area, the second servo motor will drive the second helical gear assembly to rotate together, allowing the ultra-thin glass to move with the rotation and be blocked by another blocking component until the ultra-thin glass completely enters the processing and etching area. Then the lifting cylinder will descend and take the line connecting plate down with it, so that the second helical gear assembly can descend along with it. The second helical gear assembly can descend along the direction of the linear lifting guide rail, so that the ultra-thin glass can be placed stably on the outer surface of the equal height block and the support plate.

[0024] S3: After the ultra-thin glass in S2 lands on the outer surface of the level block and the support plate, the rotation of the deceleration servo motor will drive the synchronous idler wheel assembly to rotate, so that the leveling guide plate can move along the direction of the straight track, and the first photoelectric sensor will limit the leveling guide plate, so that the leveling guide plate can clamp the ultra-thin glass and perform coarse positioning, so that the ultra-thin glass can be in the center plane of the level block.

[0025] S4: After the ultra-thin glass is clamped and coarsely positioned in S3, the first linear guide rail assembly, the second linear guide rail assembly, the slide assembly, the grating ruler and the second photoelectric sensor work together, along with the CCD assembly, to achieve automatic edge finding and rapid positioning of the ultra-thin glass, thereby achieving high-precision positioning.

[0026] S5: After the ultra-thin glass in S4 is positioned and edge-finding is performed, the laser will run and reflect the laser through the two-dimensional mirror frame, so that the laser can be emitted through the galvanometer, thereby performing high-precision etching on the ultra-thin glass to complete the etching and outflow of the ultra-thin glass.

[0027] Preferably: After the ultra-thin glass in S4 is clamped at the processing and etching position, the height sensor will scan along the ab path. When a significant height difference occurs, it will be marked as point C. Similarly, point d can be obtained. An edge can be determined from points c and d, which is a certain edge of the ultra-thin glass. By repeating the above steps, four edges can be found, which are the four contour edges of the ultra-thin glass. Subsequently, the center point of the ultra-thin glass can be found again through the center points of two adjacent edges.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: The automatic laser etching equipment for ITO film of electronic glass has a first linear guide rail assembly for X-axis movement and a second linear guide rail assembly for Y-axis movement. The first linear guide rail assembly for the X-axis adopts a gantry dual-drive mode, which can move simultaneously and has high positioning accuracy. The accuracy is even higher when the single module is repeatedly positioned, reaching ±5 micrometers, with an acceleration of 0.3G. The total load of the X-axis can reach 800kg. The linear motor has a simple structure, high positioning accuracy, low noise, and long service life, which can effectively reduce the maintenance cycle. The slide assembly for the Z-axis is a PSS140 series ball screw type slide, with a repeatability of ±0.01mm. At the same time, when the size of the ultra-thin glass is 400-1000MM, the positioning accuracy can reach 3μm, and when the size of the ultra-thin glass is 1000-1400MM, the positioning accuracy can reach ±5μm. This can reduce noise and extend the service life, greatly improve the etching accuracy, and reduce the cost of maintenance and use.

[0029] 1. Workers can adjust the guide wheels and blocking components in the X-axis direction to process ultra-thin glass of different sizes as needed. Then, the ultra-thin glass to be processed can be placed on the loading rack. As the first servo motor drives the first helical gear set to run, the rotating roller can rotate and drive the ultra-thin glass to move. The ultra-thin glass can enter the etching processing position through the guide wheels. The equipment can place and process ultra-thin glass of different specifications. After processing, it can be removed from the equipment. It can place ultra-thin glass of different specifications and improve production efficiency and reduce costs.

[0030] 2. As the first helical gear set rotates, the ultra-thin glass to be etched will be fed into the processing position. The ultra-thin glass will continue to move forward through the second servo motor and the second helical gear assembly. When the glass has fully entered the processing area, the blocking component will rise completely to block the ultra-thin glass. At the same time, the second servo motor will stop working. Then, the guide plate will be used for coarse positioning. After positioning is completed, the glass will automatically return to its original position. Then, the lifting cylinder will lower the line connecting plate, causing the second helical gear assembly to descend along the direction of the straight lifting guide rail. The second helical gear assembly will retract under the leveling block and support plate, so that the ultra-thin glass can be placed on the outer surface of the leveling block and support plate. The leveling block and support plate ensure that the ultra-thin glass can be placed flat, reducing the chance of deformation and damage. This prevents the MARK and QR code etching from shifting or deforming due to deformation during subsequent etching.

[0031] 3. The rotation of the geared servo motor drives the synchronous idler wheel assembly to move, allowing the alignment guide plate to move smoothly along the direction of the straight track. This enables the alignment guide plate to move and clamp the ultra-thin glass, allowing the ultra-thin glass to be moved and enter the center position of the processing area. This facilitates the coarse positioning of the ultra-thin glass, improves the speed of subsequent processing when aligning the position of the ultra-thin glass, and increases processing efficiency.

[0032] 4. By using a grating ruler and a second photoelectric sensor, the first and second linear guide rail assemblies can operate more accurately. Combined with the simple structure, high positioning accuracy, low noise, and long lifespan of the first and second linear guide rail assemblies, and the ball screw structure of the Z-axis slide assembly, the noise generated during movement and the service life can be reduced, which greatly improves the etching accuracy while reducing the maintenance cycle and saving processing costs.

[0033] 5. By using a CCD component and a height sensor, in conjunction with the movement of the first and second linear guide rail components, the height sensor can accurately measure the edge of the ultra-thin glass and calculate the center point based on the edge. Subsequently, the laser is moved by the first, second, and sliding table components. The laser beam is emitted from the galvanometer through the two-dimensional reflector frame, etching the middle layer of the ultra-thin glass. This allows for rapid and precise repositioning of the ultra-thin glass after coarse positioning. After etching, the etched mark and QR code can be re-inspected by the CCD component, reducing manual intervention, improving work efficiency and product quality, and ensuring high precision and stability during the processing.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figure 1-11 The present invention provides a technical solution: an automatic laser etching equipment for ITO film of electronic glass, including a cabinet assembly 1, a cover assembly 2 fixedly installed on the outer surface of the cabinet assembly 1, and the cover assembly 2 is composed of sheet metal welding, and a display, a pneumatic door and a button are installed on one side surface of the cover assembly 2. The cabinet assembly 1 is made of square tube welded as a keel, and a feeding rack 6 is fixedly installed on one side surface of the cabinet assembly 1, and a rotating roller 10 is provided between the feeding rack 6 and the cabinet assembly 1.

[0048] Example 1: In this example, to address the problem that existing technologies can only process smaller-sized ultrathin glass, and also can only process ultrathin glass of the same size, the following solution is disclosed, as detailed below. Figure 2 and Figure 6 A transmission latching mechanism is provided between the loading rack 6 and the rotating roller 10, and the transmission latching mechanism includes: a first helical gear set 8, which is fixedly installed on the outer surface of the cabinet assembly 1 and the loading rack 6 respectively. The rotating roller 10 is uniformly fixed on the outer surface of the first helical gear set 8, and the rotating roller 10 is a cylinder made of UPE material. A first servo motor 7 is fixedly installed on the side surface of the first helical gear set 8, and the output end of the first servo motor 7 is connected to the rotating part of the first helical gear set 8. A guide wheel 9 is fixedly installed on the outer surface of the cabinet assembly 1 and the loading rack 6, and the guide wheel 9 is located inside the first helical gear set 8. A blocking component 11 is fixedly installed on the outer surface of the cabinet assembly 1, and the blocking component 11 is located on one side of the first helical gear set 8.

[0049] During processing, the ultra-thin glass needs to be placed above the loading rack 6. The rotation of the first servo motor 7 drives the first helical gear set 8 to rotate, causing the ultra-thin glass to move along with the rotating roller 10. The guide wheel 9 guides the placed ultra-thin glass, allowing it to stably enter the cabinet assembly 1. The blocking assembly 11 blocks the glass. The UPE material of the rotating roller 10 has the advantages of low friction, low density, and high wear resistance, which can effectively reduce the risk of scratching the ultra-thin glass, ensure that the ultra-thin glass will not be damaged by vibration, reduce the weight of the equipment, and reduce replacement costs. By adjusting the position of the blocking assembly 11 and the guide wheel 9, as well as the positioning in the X-axis direction, it can meet the placement requirements of ultra-thin glass of different specifications. The maximum size can be up to 1400*1400mm, and it is backward compatible with 400*400mm, with a thickness of 0.3-1.5mm. It also has a plate-passing function, which can place ultra-thin glass of different sizes while improving production efficiency and reducing costs.

[0050] Example 2: In this example, to further improve the stable operation of the equipment and the safety during processing and production, the following solution is disclosed, as shown in the figure for reference. Figures 1-3 The outer surface of the cabinet component 1 is fixedly installed with an air source triplet and a fan, and a water chiller 3 is installed at one end of the cabinet component 1. A grating is installed inside the cover component 2, and a tri-color light 5 is fixedly installed on the outer surface of one end of the cover component 2. A cabinet box 4 is installed on the side of the cabinet component 1 near the water chiller 3, and the cabinet box 4 is connected to the cables of the cabinet component 1.

[0051] The operation of the equipment can be controlled through the display and buttons on the outer surface of the housing assembly 2, and the operating status of the equipment can be known in real time through the tri-color light 5. The air source triple unit and fan can effectively provide clean gas to the pneumatic components inside the equipment and lubricate them. The cabinet box 4 can be used for convenient maintenance and troubleshooting, and the grating inside the housing assembly 2 can effectively improve the safety during processing and installation.

[0052] Example 3: In this example, in order to improve the stability and flatness of ultra-thin glass during processing and reduce deformation during etching, the following solution is disclosed, as detailed below. Figures 6-7 Inside the cabinet assembly 1, height equalization blocks 13 are uniformly fixedly installed on the outer surface of one end near the first helical gear set 8. A support plate 17 is fixedly installed on the outer surface of the cabinet assembly 1, and the support plate 17 is located on both sides of the multiple height equalization blocks 13. A sliding lifting mechanism is provided between the height equalization blocks 13 and the cabinet assembly 1. The sliding lifting mechanism includes: a lifting cylinder 18, which is fixedly installed on the outer surfaces of both ends of the cabinet assembly 1. A linear lifting guide rail 16 is fixedly installed on the outer surface of the cabinet assembly 1. A line connecting plate 12 is fixedly installed at the output end of the lifting cylinder 18. A second helical gear assembly 15 is fixedly installed on the outer surface of the line connecting plate 12. A second servo motor 14 is fixedly installed on the side surface of the second helical gear assembly 15, and the output end of the second servo motor 14 meshes with the second helical gear assembly 15. The linear lifting guide rail 16 is connected to the line connecting plate 12. Another blocking assembly 11 is fixedly installed at the end of the cabinet assembly 1 away from the loading rack 6.

[0053] As the first helical gear set 8 rotates, it feeds out the ultra-thin glass. When the ultra-thin glass enters the etching area, the second servo motor 14 will rotate and drive the second helical gear assembly 15 to rotate together, allowing the ultra-thin glass to continue moving and enter the processing area. It will be blocked by another blocking component 11, and the second servo motor 14 will stop working and perform coarse positioning of the ultra-thin glass. Then, the lifting cylinder 18 will drive the line connecting plate 12 to descend, taking the second helical gear assembly 15 down with it. The second helical gear assembly 15 can descend vertically and stably along the linear lifting guide rail 16, allowing the ultra-thin glass placed on the second helical gear assembly 15 to be stably placed on the outer surface of the leveling block 13 and the support plate 17. This ensures that the ultra-thin glass is placed flat and stable on the outer surface of the leveling block 13 and the support plate 17, reducing the probability of the ultra-thin glass breaking due to deformation. It also prevents the MARK and QR code from being deformed due to the deformation of the ultra-thin glass during the etching process.

[0054] Example 4: In this example, in order to improve the processing speed and accuracy of ultra-thin glass etching during the etching process, the following solution is disclosed, as detailed below. Figure 6and Figure 8 A linear track 19 is fixedly installed on both sides of the cabinet assembly 1 and the leveling block 13, and a sliding adjustment mechanism is provided between the linear tracks 19. The sliding adjustment mechanism includes: a leveling guide plate 20, which is slidably installed on the outer surface of the linear track 19; a geared servo motor 22 is fixedly installed on the outer surface of the cabinet assembly 1 near the linear track 19; a synchronous idler wheel assembly 23 is fixedly installed on the outer surface of the cabinet assembly 1 away from the geared servo motor 22; the leveling guide plate 20 is connected to the outer surface of the synchronous idler wheel assembly 23, and the synchronous idler wheel assembly 23 is connected to the geared servo motor 22; a first photoelectric sensor 21 is fixedly installed on the outer surface of the cabinet assembly 1, and the first photoelectric sensor 21 is located between the linear tracks 19.

[0055] When the ultra-thin glass moves to the processing position via the second helical gear assembly 15, the reduction servo motor 22 will rotate and drive the synchronous idler wheel assembly 23 to rotate, allowing the alignment guide plate 20 to move along the direction of the straight track 19, so as to facilitate clamping the ultra-thin glass and bring it to the center of the equal height block 13. In conjunction with the first photoelectric sensor 21, the alignment guide plate 20 is limited, reducing the chance of the ultra-thin glass being clamped too tightly and damaged. This allows the ultra-thin glass to be moved and coarsely positioned, making it easier to find the position more quickly during subsequent ultra-thin glass etching, thus speeding up the processing efficiency and accuracy.

[0056] Example 5: In this example, to improve the accuracy of laser etching and reduce the probability of displacement between the etched QR code and the marker on the ultra-thin glass, the following solution is disclosed, as detailed below. Figures 2-5 A mobile platform assembly is fixedly installed on the outer surface of the cabinet assembly 1. The mobile platform assembly includes: a first linear guide rail assembly 24, which is fixedly installed on the outer surface of the end of the cabinet assembly 1; a second linear guide rail assembly 25 is slidably installed on the outer surface of the first linear guide rail assembly 24; and a slide table assembly 26 is slidably installed on the outer surface of the second linear guide rail assembly 25. The power for the second linear guide rail assembly 25 and the first linear guide rail assembly 24 is a linear motor, and the first linear guide rail assembly 24 adopts a gantry dual-drive mode. A grating ruler 27 is fixedly installed on the outer surfaces of the first linear guide rail assembly 24 and the second linear guide rail assembly 25, and a second photoelectric sensor 28 is fixedly installed on the outer surfaces of the second linear guide rail assembly 25 and the first linear guide rail assembly 24, respectively.

[0057] After the ultra-thin glass is coarsely positioned, the first linear guide assembly 24 and the second linear guide assembly 25 will move simultaneously and be precisely positioned. The linear motors of the first linear guide assembly 24 and the second linear guide assembly 25 have simple structures, high positioning accuracy, low noise, and long service life. The ball screw type slide of the Z-axis slide assembly 26 can reduce noise and extend service life, which can greatly improve the etching accuracy and reduce the processing cost. Furthermore, the repeatability of the equipment can be improved by the cooperation of the grating ruler 27 and the second photoelectric sensor 28, which further improves the movement accuracy, so that the MARK and QR code will not break or shift during the etching of the ultra-thin glass.

[0058] Example 6: In this example, to further improve accuracy and high-speed sampling, the following solution is disclosed: (See details below) Figures 9-10 The outer surface of the slide assembly 26 is provided with an optical etching mechanism, which includes a laser 30. The laser 30 is fixedly installed on the outer surface of the slide assembly 26, and a galvanometer 31 is fixedly installed on one side surface of the slide assembly 26. A CCD assembly 32 is fixedly installed on the outer surface of the slide assembly 26, and a height sensor 33 is fixedly installed on the side surface of the slide assembly 26. A two-dimensional reflector frame 29 is provided between the galvanometer 31 and the laser 30, and the laser 30 is a 10W picosecond ultraviolet laser.

[0059] The edge of the ultra-thin glass is located by the height sensor 33 and the CCD component 32. The center point of the ultra-thin glass is then found by the positioning of the edge. Subsequently, the laser 30 is activated and the laser is reflected by the two-dimensional reflector frame 29, allowing the laser to be emitted through the galvanometer 31 and etched in the middle layer of the ultra-thin glass. This allows for precise positioning after the coarse positioning of the ultra-thin glass. The CCD component 32 can also perform high-speed sampling and stable detection of the etched mark and QR code, achieving accurate and rapid positioning, completing high-precision etching, reducing manual intervention, improving work efficiency and product quality, ensuring high precision and high stability in the processing, avoiding product damage, and enabling wide application.

[0060] The method of using the automated laser etching equipment for the ITO film of this electronic glass includes the following steps:

[0061] S1: The worker needs to place the ultra-thin glass to be etched on the top of the loading rack 6. The rotation of the first servo motor 7 drives the first helical gear set 8 to rotate, so that the rotating roller 10 can rotate together, drive the ultra-thin glass to move, and guide it through the guide wheel 9, so that the ultra-thin glass to be processed can be stored inside the cabinet assembly 1, and the excess ultra-thin glass can be blocked by the lifting of the blocking assembly 11.

[0062] S2: After the ultra-thin glass in S1 enters the processing etching area, the second servo motor 14 will drive the second helical gear assembly 15 to rotate together, so that the ultra-thin glass can move with the rotation and be blocked by another blocking assembly 11 until the ultra-thin glass completely enters the processing etching area. Then the lifting cylinder 18 will descend and take the line connecting plate 12 down with it, so that the second helical gear assembly 15 can descend along with it, so that the second helical gear assembly 15 can descend along the direction of the linear lifting guide rail 16, so that the ultra-thin glass can be placed stably on the outer surface of the equal height block 13 and the support plate 17.

[0063] S3: After the ultra-thin glass in S2 lands on the outer surface of the leveling block 13 and the support plate 17, the rotation of the reduction servo motor 22 will drive the synchronous idler wheel assembly 23 to rotate, so that the leveling guide plate 20 can move along the direction of the straight track 19, and the first photoelectric sensor 21 will limit the leveling guide plate 20, so that the leveling guide plate 20 can clamp the ultra-thin glass and perform coarse positioning, so that the ultra-thin glass can be in the center plane of the leveling block 13;

[0064] S4: After the ultra-thin glass is clamped and coarsely positioned in S3, the first linear guide rail assembly 24, the second linear guide rail assembly 25, the slide assembly 26, the grating ruler 27 and the second photoelectric sensor 28 are used in conjunction with the CCD assembly 32 to realize automatic edge finding and rapid positioning of the ultra-thin glass, thereby achieving high-precision positioning.

[0065] S5: After the ultra-thin glass in S4 is positioned and edge-finding is performed, the laser 30 will run and reflect the laser through the two-dimensional reflector frame 29, so that the laser can be emitted through the galvanometer 31, thereby performing high-precision etching on the ultra-thin glass to complete the etching and outflow of the ultra-thin glass.

[0066] After the ultra-thin glass in S4 is clamped at the etching position, the height sensor 33 will scan along the ab path. When a significant height difference is found, it will be marked as point C. Similarly, point d can be obtained. An edge can be determined from points c and d, which is a certain edge of the ultra-thin glass. By repeating the above steps, four edges can be found, which are the four contour edges of the ultra-thin glass. Subsequently, the center point of the ultra-thin glass can be found again by the center point of two adjacent edges.

[0067] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
