Description

Technical Field

[0001] This invention relates to the field of glass substrate processing technology, and more specifically to a glass substrate processing apparatus for liquid crystal displays. Background Technology

[0002] Liquid crystal displays (LCDs) are the core components of modern information displays, widely used in televisions, computers, smartphones, and various smart terminals. Glass substrates, as the key basic material for LCD panels, directly determine the imaging quality and product yield of the display panel due to their surface flatness, thickness uniformity, and internal stress distribution. As display technology develops towards higher resolution, larger sizes, and thinner profiles, increasingly stringent requirements are placed on the processing precision of glass substrates. Currently, the mainstream production processes for glass substrates mainly include overflow melting, float glass, and perforation bottom drawing. Among these, overflow melting has become the dominant technology for high-end display glass substrates because it can obtain a double-sided original gloss surface. However, the forming of the glass substrate is only the starting point of the industrial chain. The semi-finished product after forming must undergo a series of precision processing steps to meet the requirements of the panel manufacturing process. Typical post-processing steps include cutting, grinding, polishing, thinning, and cleaning. The processing quality of these steps directly affects the final quality of the substrate.

[0003] In the processing of glass substrates, surface scratches are a common quality problem that has long plagued the industry. Processing debris often remains during the process, and there is also the problem of secondary pollution caused by polishing fluid residue, which requires some improvements. Summary of the Invention

[0019] Glass substrate processing and cleaning operations: S1. The camera 15 detects the number of stacked placement bases 23 and automatically performs cleaning and dust removal operations. The dust removal efficiency and moving speed are adjusted according to the different sizes of placement bases 23, and cleaning and dust removal operations are performed on different positions of the glass substrate.

[0020] Specifically, during the glass substrate production process, a cutting operation is required. The worker first manually places the glass substrate 231 into the feed inlet 11, then turns on the workshop power. At this time, the glass substrate processing box 1 starts, and the equipment program starts. The equipment program controls the glass substrate cutting device 14 to process the glass substrate 231. The processed glass substrate 231 is then conveyed backward to the placement base 23, and then further conveyed to the mobile transport table 26 for processing and cleaning. The equipment program first controls the second electric slide rail 25 to start, and the second electric slide rail 25 drives the mobile transport table 26 upward. The device moves to one side of the glass substrate cutting device 14, and then the equipment program controls the clamping robot in the glass substrate cutting device 14 to start, placing the placement base 23 sequentially on the moving transport table 26. At this time, the equipment program detects the stacking number of placement base 23 through the camera 15. The equipment program sets the stacking number value of placement base 23 to a range of A1, which can be adjusted according to specific needs. When the equipment program detects that the stacking number value of placement base 23 reaches A1, the equipment program controls the moving cleaning operation. At this time, the equipment program detects the size and position of the glass substrate 231 through the camera 15 and... The system compares the value with the set value and then controls the movement and cleaning operation. The equipment program sets the size value range to B1~B2, which can be adjusted according to specific needs. The dust removal wind speed range of the filter fan 31 is C1~C3, which can be adjusted according to specific needs. The moving speed range of the second electric slide rail 25 is D1~D2, which can be adjusted according to specific needs. When the equipment program detects a size value of B1, it determines that the glass substrate 231 on the base 23 is too small. The equipment program controls the filter fan 31 to start and adjust the wind speed to C1. The first electric valve 38 and the two sets of third electric valves... When valve 382 is opened, filter fan 31 uses first cleaning nozzle 331 and second cleaning nozzle 332 to suction and clean the dust and processing debris accumulated at the bottom of the moving transport table 26. Then, the equipment program controls the second electric slide rail 25 to start, and the moving speed is adjusted to D2. The second electric slide rail 25 drives the moving transport table 26 to move quickly downward into the cleaning chamber 16. During the movement of the moving transport table 26, filter fan 31 uses fifth cleaning nozzle 351 to suction and clean the processing debris in the gaps between several sets of stacked bases 23, thereby improving cleaning efficiency.

[0021] When the equipment program detects a size value of B2, it determines that the glass substrate 231 on the set of placement bases 23 is too large. The equipment program controls the filter fan 31 to start, and the wind speed is adjusted to C2. The first electric valve 38 and the two sets of third electric valves 382 are opened. The filter fan 31 uses the first cleaning nozzle 331 and the second cleaning nozzle 332 to suck up and clean the dust and processing debris accumulated at the bottom of the moving transport table 26. Then, the equipment program controls the second electric slide rail 25 to start, and the moving speed is adjusted to D1. The second electric slide rail 25 drives the moving transport table 26 to slowly move downward into the cleaning chamber 16. During the movement of the moving transport table 26, the filter fan 31 uses the fifth cleaning nozzle 351 to suck up and clean the processing debris in the gaps between the stacked sets of placement bases 23, improving the cleaning efficiency. After completing the above operations, the equipment program controls the next operation.

[0022] By using the camera 15, filter fan 31, second electric slide rail 25, and equipment program in conjunction with the system, the number of stacked placement bases 23 can be automatically detected, and cleaning operations can be performed automatically on them. During the cleaning process, the dust removal speed and moving speed can be adjusted according to the different sizes of the glass substrates on the placement bases 23. The dust accumulated at the bottom of the moving transport table 26 and the processing debris generated can be sucked up and cleaned. At the same time, the processing debris in the gaps between several sets of placement bases 23 can be sucked up and cleaned. When the glass substrate size is small, the moving speed is increased to improve the cleaning efficiency. When the glass substrate size is large, the moving speed is reduced to extend the suction time for processing debris in the gaps between several sets of placement bases 23, ensuring the cleaning effect.

[0023] Glass substrate rinsing operation: S2. The size of the glass substrate 231 is detected by the camera 15, and the rinsing force and rinsing angle are changed according to the size to ensure that the cleaning liquid fully contacts the glass substrate. At the same time, the humidity value in the cleaning chamber 16 is detected by the humidity detector 34, and dehumidification and moisture prevention operations are performed according to the different humidity values.

[0024] Specifically, after completing the above operations, the equipment program controls the rinsing operation. The equipment program sets the pumping volume of the micro pump 371 to a range of X1~X2, which can be adjusted according to specific needs. The humidity detector 34 detects humidity values ​​in the range of Y1, which can also be adjusted according to specific needs. When the equipment program detects that the size of the glass substrate 231 is B1, the equipment program controls the micro pump 371 to start, the pumping volume is adjusted to X1, the two sets of fourth electric valves 383, the two sets of third electric valves 382, ​​and the fifth electric valve 391 are opened, and the first electric valve 38 and the second electric valve 381 are closed. The micro pump 371 pumps the cleaning solution into the first... The cleaning fluid in the three conveying hoses 37 is then sprayed outward in a mist form from the two sets of third cleaning nozzles 333 to clean the glass substrates 231 on the stacked placement bases 23. At the same time, the equipment program controls the second electric slide rail 25 to start, with a moving speed of D1. The second electric slide rail 25 drives the moving transport table 26 to move slowly upward. During the movement of the moving transport table 26, the cleaning fluid in the third conveying hoses 37 will be diverted to the fifth cleaning nozzle 351 and sprayed outward. The fifth cleaning nozzle 351 washes and cleans the processing debris in the gaps between the stacked placement bases 23 to avoid debris residue and prevent cleaning dead corners.

[0025] When the equipment program detects that the size of the glass substrate 231 is B2, the program controls the micro pump 371 to start, the pumping volume is adjusted to X2, and the two sets of fourth electric valves 383, second electric valve 381, and fifth electric valve 391 are opened, while the first electric valve 38 and the two sets of third electric valves 382 are closed. The micro pump 371 pumps the cleaning fluid into the third delivery hose 37, and then sprays it outward in a water mist from the two sets of third cleaning nozzles 333 to clean the glass substrates 231 stacked on the base 23. Simultaneously, the equipment program controls the second electric slide rail 25 to start, with a moving speed of D1. The second electric slide rail 25 drives the moving transport table 26 to move slowly upward. During the movement of the moving transport table 26, the cleaning fluid in the third conveying hose 37 will be diverted to the fourth cleaning nozzle 35 and the fifth cleaning nozzle 351 and sprayed outward. The fourth cleaning nozzle 35 and the fifth cleaning nozzle 351 can respectively rinse and clean the processing debris in the gaps between different areas on both sides of the stacked sets of placement bases 23, avoiding debris residue and preventing cleaning dead corners.

[0026] After the above rinsing operation is completed, the equipment program only controls the two sets of third electric valves 382 to open, while the other electric valves are closed. The filter fan 31 starts and the wind speed is adjusted to C3. The filter fan 31 removes the humid gas generated during cleaning through the first cleaning nozzle 331 and the second cleaning nozzle 332.

[0027] After completing the above operations, the equipment program detects the humidity value inside the cleaning chamber 16 through the humidity detector 34 and compares it with the set value. When the humidity detector 34 detects a humidity value > Y1, the equipment program determines that the inside of the cleaning chamber 16 is damp and a moisture removal operation is required. The equipment program controls the first electric valve 38, the second electric valve 381, and two sets of third electric valves 382 to open, while the remaining electric valves are all closed. The filter fan 31 starts and the wind speed is adjusted to C3. The filter fan 31 removes the humid gas generated during cleaning through the first cleaning nozzle 331, the second cleaning nozzle 332, the fourth cleaning nozzle 35, and the fifth cleaning nozzle 351. During the removal process, the equipment program continuously detects the humidity value inside the cleaning chamber 16 through the humidity detector 34 and compares it with the set value. When the humidity detector 34 detects a humidity value < Y1, the equipment program controls the filter fan 31 to stop and the remaining components to reset.

[0028] By using the micro pump 371, five sets of cleaning nozzles, and the equipment program in conjunction with each other, the rinsing force and rinsing angle can be adjusted according to the size of the glass substrate. When cleaning small glass substrates, the rinsing force is reduced to prevent the cleaning fluid from splashing everywhere, and the moving speed is reduced to ensure that the cleaning fluid fully contacts the glass substrate. When cleaning large glass substrates, the rinsing force is increased to avoid the residue of processing debris. At the same time, the glass substrate is rinsed from multiple angles to ensure rinsing efficiency. By using the humidity detector 34 in conjunction with the equipment program, the humidity value in the cleaning chamber 16 can be detected, and dehumidification and moisture prevention operations can be performed according to the different humidity values ​​to prevent the accumulation of humid gas.

[0029] Glass substrate processing and inspection procedures: S3. The cleaned glass substrate is clamped and transported by the second electric slide rail 25 and the clamping conveyor 27. After the transport is completed, the glass substrate inspection robot 22 inspects the cleaning effect of the glass substrate and performs secondary cleaning or unloading operation according to the different inspection results.

[0030] Specifically, after completing the above operations, the equipment program controls the processing and testing operations. The equipment program controls the second electric slide rail 25 to start, and the second electric slide rail 25 drives the moving transport table 26 to move upward to one end of the clamping transport table 27. Then, the equipment program controls the clamping transport table 27 to clamp the placement base 23 on the moving transport table 26. After clamping, the equipment program controls the first electric slide rail 24 to start, and the first electric slide rail 24 drives the clamping transport table 27 to move the clamped placement base 23 to the glass substrate transport table 21. Then, the equipment program controls the glass substrate inspection robot 22 to inspect the glass substrate 231 placed on the placement base 23 and send the inspection qualified information to the staff. After sending, the equipment program controls the glass substrate transport table 21 to start, and transport the placement base 23 to the discharge port 12 for the staff to grab.
