[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only show portions relevant to the present invention, not all of them.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention.

[0039] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0040] like Figure 1-Figure 5 As shown, the glass processing equipment of this embodiment includes a conveying unit and an edging unit. Figure 1 The XO direction is the first direction, the OY direction is the second direction, and the OZ direction is the third direction. Optionally, in this embodiment, the first direction and the second direction are both horizontal directions, the second direction is perpendicular to the first direction, and the third direction is a vertical direction. The conveying unit is used to support the glass substrate 900, and the glass substrate 900 can move along the first direction on the conveying platform of the conveying unit, and the edging unit is arranged on one side of the conveying platform along the second direction.

[0041] Optionally, in this embodiment, the object to be processed is a glass substrate 900, which is composed of a white glass base and a surface film layer on its upper surface. At the same time, the surface film layer is divided into two parts: a glass substrate effective area and a glass substrate invalid area. The operator can hold the glass substrate invalid area and the two sides of the glass substrate 900 to flexibly move and flip the glass substrate 900.

[0042] Optionally, the conveying unit includes a plurality of conveying rollers 16, which are arranged in two rows along the second direction. Each row of conveying rollers 16 includes a plurality of conveying rollers 16 spaced sequentially along the first direction. The rotation axes of the conveying rollers 16 extend along the second direction, thereby ensuring rolling contact between the glass substrate 900 and the conveying rollers 16, and allowing the glass substrate 900 to advance in the first direction. Optionally, the distance between adjacent conveying rollers 16 can be flexibly adjusted based on the size of the glass substrate 900 and the position of the support points.

[0043] The edging unit includes an edging wheel 1, a first pressure sensor 2, and a first display 3. The edging wheel 1 is rotatable about its own axis. The first detection end of the first pressure sensor 2 and the sidewall of the edging wheel 1 both press against the side edge of the glass substrate 900 to be ground. Along a first direction, the first detection end is located upstream or downstream of the edging wheel 1. The first display 3 is communicatively connected to the first pressure sensor 2 so that the first display 3 can display the detection results of the first pressure sensor 2. Optionally, the edging wheel 1 is a diamond grinding wheel to ensure good wear resistance.

[0044] Alternatively, as Figure 2 and Figure 5 As shown, the position of the diamond grinding wheel in the third direction needs to be adjusted so that the center line of the outer arc groove of the diamond grinding wheel along the third direction is flush with the center line of the glass substrate 900 along its thickness direction.

[0045] By real-time monitoring of the detection results of the first pressure sensor 2, the thrust applied to the glass substrate 900 in a direction perpendicular to the first direction can be adjusted at any time. This thrust can be applied by a worker or by a mechanical clamping device such as a manipulator. This thrust is applied to the glass substrate 900 and has a component directed in a second direction toward the edging wheel 1, thereby causing the glass substrate 900 to abut against the edging wheel 1. By precisely controlling the component of this force through real-time monitoring of the detection results of the first pressure sensor 2, excessive pressure between the glass substrate 900 and the edging wheel 1 can be avoided, thereby preventing microcracks, microscratches, and even film shedding on the film surface. This ensures the integrity of the film and improves the strength, conductivity, and light transmittance of the glass, thereby ensuring the mechanical strength, optoelectronic performance, and yield rate of the perovskite solar cell.

[0046] To further improve the edging effect, the edging unit optionally further includes a second pressure sensor 4 and a second display element 5. Along the first direction, the first detection end is located downstream of the edging wheel 1, and the second detection end of the second pressure sensor 4 presses against the side to be edged. Along the first direction, the second detection end and the first pressure sensor 2 are located on either side of the edging wheel 1, respectively, that is, the second detection end is located upstream of the edging wheel 1. The second display element 5 is communicatively connected to the second pressure sensor 4 so that the second display element 5 can display the detection results of the second pressure sensor 4. Specifically, the second detection end of the second pressure sensor 4 presses against the unground side of the side to be edged, while the first detection end of the first pressure sensor 2 presses against the ground side of the side to be edged.

[0047] During the contact between the glass substrate 900 and the diamond grinding wheel, the glass substrate 900 is guided by the pressure sensor. At the same time, the pressure sensor can also capture the pressure changes between the glass substrate 900 and the diamond grinding wheel in real time, avoiding the glass substrate 900 from breaking due to excessive pressure or uneven edge grinding due to insufficient pressure, thereby ensuring the effect and accuracy of edge grinding. The glass substrate 900 can also be tested for edge grinding to determine the most appropriate pressure range, which can further improve the monitoring effect during subsequent pressure monitoring. During the initial edge grinding process, a light pressure and slow advance method is used to avoid applying excessive pressure to the glass substrate 900 to prevent the glass substrate 900 from breaking. Optionally, the first pressure sensor 2 and the second pressure sensor 4 can use a Hall sensor or an optical pressure sensor, etc., to accurately measure tiny pressure changes.

[0048] Optionally, the edging unit further includes a liquid spraying assembly 6 for spraying coolant onto the edging wheel 1 and / or the side to be ground. Optionally, the edging unit further includes a guide plate 7 and a liquid storage tank 8. The guide plate 7 is located below the liquid spraying assembly 6, and the liquid storage tank 8 is located below the guide plate 7, so that the coolant can enter the liquid storage tank 8 through the guide plate 7.

[0049] During the edge grinding process, the nozzle of the liquid spraying assembly 6 can flexibly adjust the spraying position and angle. The sprayed coolant flows through the grinding area of ​​the diamond grinding wheel and then flows into the liquid storage tank 8 through the guide plate 7. The injection of coolant is beneficial to lowering the temperature of the grinding area and reducing burns or cracks on the glass surface film.

[0050] Optionally, a side baffle 17 is further provided on the side of the conveying unit where the squaring wheel 1 is provided, and the side baffle 17 can prevent the coolant from splashing everywhere.

[0051] Optionally, the edging unit further includes a bracket 18 , a conveying roller 16 of the conveying unit is arranged on the top of the bracket 18 , the bottom of the bracket 18 can also fix the liquid storage tank 8 , and a side baffle 17 can be arranged on the side of the bracket 18 .

[0052] Optionally, the edging unit further includes a drive assembly 9, which is disposed on a side of the edging wheel 1 away from the glass substrate 900. The drive assembly 9 is capable of driving the edging wheel 1 to rotate and adjusting the position of the edging wheel 1 in a direction perpendicular to the conveying platform. Optionally, the drive assembly 9 includes at least a fixed block, a rotating drive member, and a movable drive member. The movable drive member is disposed on the fixed block to prevent the movable drive member from moving during the edging process. The rotating drive member is connected to the output end of the movable drive member, and the rotating shaft of the edging wheel 1 is connected to the output end of the rotating drive member. Optionally, the rotating drive member is a motor, and the movable drive member is a cylinder or a linear motor.

[0053] Optionally, the glass processing equipment further includes a cleaning and drying unit, and the glass substrate 900 that has completed the edging process can be directly cleaned and dried, making the process more compact and efficient.

[0054] Optionally, the cleaning and drying unit further includes a housing 13, which is fixedly connected to the bracket 18. Optionally, the cleaning and drying unit includes a cleaning liquid nozzle 10 and a drying air nozzle 11 disposed within the housing 13. The glass substrate 900 is placed within the housing 13. The cleaning liquid nozzle 10 is used to spray cleaning liquid onto the glass substrate 900, and the drying air nozzle 11 is used to blow drying air onto the glass substrate 900. Optionally, both the cleaning liquid nozzle 10 and the drying air nozzle 11 are mounted on an inner wall of the housing 13 to facilitate access by an operator.

[0055] Optionally, the cleaning and drying unit further includes a liquid pipe and a cleaning liquid regulating valve 14. The cleaning liquid regulating valve 14 is disposed on the liquid pipe, and the cleaning liquid nozzle 10 is connected to the liquid pipe. Adjusting the cleaning liquid regulating valve 14 can adjust the flow rate and / or hydraulic pressure of the cleaning liquid. Optionally, in this embodiment, the cleaning liquid is water. Optionally, in this embodiment, the cleaning liquid regulating valve 14 includes a flow valve and / or a pressure valve.

[0056] Optionally, the washing and drying unit further includes an air duct and a drying air regulating valve 15. The drying air regulating valve 15 is disposed on the air duct, and the drying air nozzle 11 is connected to the air duct. Adjusting the drying air regulating valve 15 can adjust the flow rate and / or pressure of the drying air. Optionally, in this embodiment, the drying air regulating valve 15 includes a flow valve and / or a pressure valve.

[0057] Optionally, the cleaning and drying unit further includes a support rod 12, which includes an L-shaped support section 121. The angle between the first side of the L-shaped support section 121 and the vertical direction is adjustable. The L-shaped support section 121 is used to support the glass substrate 900. Optionally, the support rod 12 further includes a connecting section 122 and a rotating shaft 123. One end of the connecting section 122 is connected to the inner wall of the housing 13, and the other end is connected to the L-shaped support section 121 via the rotating shaft 123. The rotating shaft 123 has damping. By adjusting the angle between the L-shaped support section 121 and the connecting section 122, the L-shaped support section 121 can be adjusted at a large angle and fixed in place.

[0058] Optionally, the connecting section 122 is arranged on the inner wall opposite to the inner wall of the box 13 where the cleaning liquid nozzle 10 and the drying air nozzle 11 are arranged, so as to maximize the use of the space inside the box 13 and facilitate the operator or robot to place the glass substrate 900.

[0059] Optionally, the connecting segment 122 extends along the second direction, the plane on which the L-shaped support segment 121 lies is perpendicular to the first direction, and at least two support rods 12 are provided, with the two support rods 12 spaced apart to jointly support the glass substrate 900. The glass substrate 900 is placed on the L-shaped support segment 121, primarily resting on the edge connected to the connecting segment 122, with the other edge of the L-shaped support segment 121 supporting the bottom edge of the glass substrate 900.

[0060] The reasonable placement angle of the L-shaped support segment 121 can be designed according to the hydrophilicity and surface tension of the surface film layer of the glass substrate 900, so as to facilitate the guidance and flow of water during the cleaning and drying process, which is beneficial to the cleaning and drying of the glass substrate 900. The contact area between the two L-shaped support segments 121 and the glass substrate 900 is very small, and the distance between the two L-shaped support segments 121 is adjustable, that is, the position of the connecting segment 122 on the box body 13 is adjustable. Optionally, the connecting segment 122 is screwed to the box body 13, and a plurality of screw holes are provided on the box body 13. The position of the connecting segment 122 can be adjusted by selecting different screw holes. The L-shaped support segment 121 supports the bottom of the substrate inactive area of ​​the glass substrate 900, which is beneficial to dry out as much moisture as possible in the gap between the L-shaped support segment 121 and the glass substrate 900 during the drying process.

[0061] During the cleaning process, the operator holds the liquid pipe and cleaning liquid nozzle 10 at a certain angle to the glass substrate 900, then swings it back and forth along the direction of water flow on the glass substrate 900. The outlet of the cleaning liquid nozzle 10 is a long and narrow structure, used to generate a high-pressure water flow to concentrate the water flow energy. At the same time, the water flow rate and water pressure can be flexibly adjusted by adjusting the cleaning liquid regulating valve 14. During the drying process, the operator holds the air pipe and drying air nozzle 11 at a certain angle to the glass substrate 900, then swings it back and forth along the direction of water flow on the glass substrate 900. The outlet of the drying air nozzle 11 is designed as a long and narrow structure, which uses the Coanda effect and its special internal geometry to form a high-intensity, uniform airflow. At the same time, the air flow rate and air pressure can be flexibly adjusted by the drying air pressure regulating valve.

[0062] This embodiment also provides a glass processing method, which uses the above-mentioned glass processing equipment.

[0063] The glass processing method includes a preparation stage, an edge grinding stage, a cleaning stage, a drying stage and a testing stage.

[0064] Preparation stage: According to the size and edge grinding depth a of the glass substrate 900 of the perovskite solar cell to be processed p , adjust the vertical position of the grinding wheel 1 to ensure that the center line of the outer arc groove of the diamond grinding wheel is aligned with the center line of the glass substrate 900. Adjust the distance between the conveying rollers 16 to ensure that the glass substrate 900 moves smoothly in the first direction. Set the speed v of the grinding wheel 1 s , adjust the spraying position and spraying angle of the spraying component 6.

[0065] Edging stage: Start the driving assembly 9 and the liquid spraying assembly 6, place the glass substrate 900 on the conveying platform and press against the second pressure sensor 4. During the movement of the glass substrate 900 along the first direction, the edging wheel 1 grinds the side to be ground. According to the detection results of the first pressure sensor 2 and the second pressure sensor 4, the thrust applied to the glass substrate 900 along the width direction of the conveying platform is adjusted in real time to ensure that the detection results of the first pressure sensor 2 and the second pressure sensor 4 fluctuate within a reasonable range.

[0066] After the edge grinding of the first side of the glass substrate 900 is completed, the edge grinding quality is evaluated by visual observation, touch method or ultra-depth of field microscope inspection method. If it meets the processing requirements, the second, third and fourth side edges of the glass substrate 900 are processed in sequence with the set process parameters. Otherwise, the edge grinding process parameters are redesigned and the above steps are repeated.

[0067] Cleaning stage: First, the inclination angle of the L-shaped support section 121 of the support rod 12 is set according to the hydrophilicity and surface tension of the glass substrate 900 , and the glass substrate 900 is placed on the L-shaped support section 121 .

[0068] Turn on the cleaning liquid switch, adjust the cleaning liquid regulating valve 14, spray high-pressure cleaning liquid on the glass substrate 900, aim the water nozzle of the cleaning liquid nozzle 10 at the top of the glass substrate 900, and clean it back and forth from top to bottom several times. After cleaning is completed, turn off the cleaning liquid switch and hang the cleaning liquid nozzle 10.

[0069] Drying stage: Turn on the drying air switch, adjust the drying air regulating valve 15, spray high-pressure drying air on the glass substrate 900, aim the air outlet of the drying air nozzle 11 at the uppermost end of the glass substrate 900, and blow back and forth from top to bottom several times. After drying is completed, turn off the drying air switch and hang the drying air nozzle 11.

[0070] Inspection stage: Place the cleaned and dried glass substrate 900 under a strong light to observe the cleaning and drying effects. If it meets the processing requirements, it is unloaded and stored in a drying oven. Otherwise, redesign the cleaning and drying process parameters and repeat the above cleaning and drying steps.

[0071] The application of this glass processing method can help improve the strength, conductivity and light transmittance of glass, thereby helping to improve the mechanical strength, photoelectric performance and yield of perovskite solar cells.

[0072] Taking into account the special edge grinding requirements of the glass substrate 900 of the perovskite solar cell, the glass processing equipment for the perovskite solar cell provided in this embodiment simplifies the mechanical structure of the equipment as much as possible. It only consists of a conveying unit, an edge grinding unit, and a cleaning and drying unit, realizing a mechanically assisted semi-manual equipment with a very simple overall structure that integrates edge grinding, cleaning, and drying functions.

[0073] With the mechanical assistance of conveyor rollers 16, pressure sensors, and L-shaped support segments 121 on the conveyor platform, processes such as edge grinding, cleaning, and drying of the glass substrate 900 can be quickly and manually completed, offering a wide range of operational freedom and flexibility. Since the active area of ​​the film layer on the glass substrate 900 is not directly contacted by external objects, the entire process is completed by manually holding the inactive area at the edge of the glass substrate 900, thus ensuring the surface integrity of the active area of ​​the film layer.

[0074] By precisely aligning the speed- and position-adjustable edging wheel 1 with the edge of the glass substrate 900, and by real-time monitoring by a pressure sensor, high-precision machining of the side edge of the glass substrate 900 to be ground can be achieved. Starting from first principles, by designing an L-shaped support section 121 with an adjustable bending angle and built-in damping function, and by incorporating a cleaning and drying unit capable of providing high-pressure water flow and high-speed air, high cleanliness and rapid drying of the glass substrate 900 can be achieved. Furthermore, the entire process is highly coherent, ensuring high machining efficiency. The entire machine utilizes the edging wheel 1, cleaning fluid nozzle 10, and drying air nozzle 11 as core components, with a conveyor roller 16, pressure sensor, and L-shaped support section 121 as key components, and a profile frame and housing 13 as auxiliary components. It does not involve complex electromechanical transmission units, resulting in manageable investment costs and easy maintenance. In summary, this embodiment achieves a mechanically assisted manual edging, cleaning, and drying function for glass substrates 900, characterized by a simple structure, flexible operation, good film integrity, excellent machining accuracy, high machining efficiency, and low investment costs.

[0075] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
