[0021] Preferably: after the ultra-thin glass in S4 is clamped at the processing etching position, the height measuring sensor will scan along the ab path. When an obvious height difference appears, 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 working 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.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the automatic laser etching equipment for the ITO film of the electronic glass: the first linear guide assembly is for X-axis movement, the second linear guide assembly is for Y-axis movement, the first linear guide assembly of the X-axis adopts a gantry dual-drive mode to move simultaneously, and has high positioning accuracy, and the accuracy is higher when a single module is repeatedly positioned, which can reach ±5 microns, acceleration 0.3G, and the total load of the X-axis can reach 800kg, and the linear motor has a simple structure, high positioning accuracy, low noise and long service life, which can effectively reduce the maintenance cycle, and the Z-axis slide assembly is a pss140 series ball screw slide with a repeated positioning accuracy 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, which can reduce noise and extend the service life, and can greatly improve the etching accuracy and reduce the cost of maintenance.

[0023] 1. Workers can adjust the guide wheel and the blocking assembly in the direction of the X-axis according to the needs of processing ultra-thin glasses of different sizes, and then place the processed ultra-thin glass on the top of the loading rack. As the first servo motor drives the first spiral gear set to operate, the rotating roller can rotate and drive the ultra-thin glass to move, so that the ultra-thin glass can enter the etching processing position through the guidance of the guide wheel, so that the equipment can place and process ultra-thin glasses of different specifications, and can be removed from the equipment after the processing is completed. Ultra-thin glasses of different specifications can be placed and production efficiency can be improved to reduce costs; 2. With the rotation of the first helical gear set, the ultra-thin glass to be etched will be sent to the processing position, and the ultra-thin glass will continue to move forward through the second servo motor and the second helical gear assembly. When the glass completely enters the processing area, the blocking assembly will be completely lifted to block the ultra-thin glass, and the second servo motor will stop working. Then, the regular guide plate will be used for coarse positioning, and it will automatically return to its original position after the positioning is completed. Then, the lifting cylinder will descend with the line body connecting plate, so that the second helical gear assembly will descend along the direction of the linear lifting guide rail, and the second helical gear assembly will be retracted under the equal height block and the support plate, so that the ultra-thin glass can be placed on the outer surface of the equal height block and the support plate. The equal height block and the support plate enable the ultra-thin glass to be placed flat, reducing the probability of deformation and damage, so that the MARK and QR code etching will not be offset or deformed due to deformation during subsequent processing and etching; 3. The synchronous idler assembly is driven to move by the rotation of the deceleration servo motor, so that the regular guide plate can be smoothly displaced along the direction of the linear track, so that the regular guide plate can move and clamp the ultra-thin glass, so that the ultra-thin glass can be moved and enter the center of the processing area, which is convenient for rough positioning of the ultra-thin glass, improves the speed of subsequent processing to align the position of the ultra-thin glass, and improves the processing efficiency; 4. Through the grating ruler and the second photoelectric sensor, the first linear guide assembly and the second linear guide assembly can be more accurate during operation. With the simple structure, high positioning accuracy, low noise and long service life of the first linear guide assembly and the second linear guide assembly, and the ball screw structure of the Z-axis slide assembly, the noise generated during mobile operation and the service life can be reduced, the etching accuracy is greatly improved, the maintenance cycle is reduced, and the processing cost is saved; 5. Through the CCD component and the height sensor, in coordination with the movement of the first linear guide assembly and the second linear guide assembly, the height sensor can accurately measure the edge of the ultra-thin glass, and calculate the center point through the edge of the ultra-thin glass, and then the laser can be driven to move by driving the first linear guide assembly, the second linear guide assembly and the slide assembly, and the laser is emitted from the galvanometer through the two-dimensional reflector frame in coordination with the operation of the laser, and is etched in the middle layer of the ultra-thin glass, so that the ultra-thin glass can be quickly and accurately positioned again after rough positioning, and after etching is completed, the etched MARK and QR code can be re-inspected by the CCD component again, reducing manual participation, improving work efficiency and product quality, and ensuring high precision and high stability in the processing process.

Then, the laser 30 is started and the two-dimensional reflector frame 29 reflects the laser, so that the laser can be emitted through the galvanometer 31 and etched at the middle interlayer position of the ultra-thin glass, so that the ultra-thin glass can be accurately positioned again after rough positioning, and the CCD component 32 can be used for high-speed sampling and stable detection of the MARK and two-dimensional code after etching, so as to achieve accurate and fast positioning, complete high-precision etching, reduce manual participation, improve work efficiency and product quality, ensure high precision and high stability in the processing process, avoid damage to the product and have a wide range of applications.

[0040] The method for using the ITO film automatic laser etching device for electronic glass comprises the following steps: S1: A worker is required to place the ultra-thin glass to be etched on the top of the loading rack 6, and the rotation of the first servo motor 7 drives the first spiral 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 raising the blocking assembly 11; S2: After the ultra-thin glass in S1 enters the processing and 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 and etching area, and then the lifting cylinder 18 will descend and bring the line body connecting plate 12 down together, so that the second helical gear assembly 15 can follow and descend together, 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 stably placed on the outer surface of the equal height block 13 and the support plate 17; S3: After the ultra-thin glass in S2 lands on the outer surface of the equal height block 13 and the support plate 17, the rotation of the deceleration servo motor 22 drives the synchronous idler assembly 23 to rotate, so that the regular guide plate 20 can move along the direction of the linear track 19, and the first photoelectric sensor 21 is used to limit the regular guide plate 20, so that the regular guide plate 20 can clamp the ultra-thin glass and perform rough positioning, so that the ultra-thin glass can be located at the center plane of the equal height block 13; S4: After the ultra-thin glass in S3 is clamped and roughly positioned, the first linear guide assembly 24, the second linear guide assembly 25, the slide assembly 26, the grating ruler 27 and the second photoelectric sensor 28 cooperate with the CCD assembly 32 to realize automatic edge finding and rapid positioning of the ultra-thin glass, thereby achieving high-precision positioning; S5: After the ultra-thin glass in S4 is positioned and edged, 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 etching the ultra-thin glass with high precision to complete the etching and outflow of the ultra-thin glass.

[0041] After the ultra-thin glass in S4 is clamped at the processing etching position, the height measuring sensor 33 will scan along the ab path. When an obvious height difference appears, 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.
