Description

Panel cleaning parameter adjustment method and panel treatment system

This invention relates to a cleaning parameter adjustment method and processing system, and more particularly to a panel cleaning parameter adjustment method and panel processing system.

In existing panel processing systems, personnel must wait until the system generates measurement results before adjusting at least one parameter based on unsatisfactory results and their own experience. Therefore, this conventional processing method is inefficient. Furthermore, in practice, it often happens that a large number of panels are scrapped before personnel can adjust the parameters.

This invention discloses a panel cleaning parameter adjustment method and a panel processing system, which is mainly used to improve the existing technology, where relevant personnel must wait for the final measurement results of the panel before they can adjust the parameters of the panel processing system based on experience, which may lead to a large amount of substrate damage.

One embodiment of the present invention discloses a panel cleaning parameter adjustment method, applicable to a panel processing system. The panel processing system includes a panel cleaning device, a detection device, and a processing unit. The processing unit is electrically connected to the panel cleaning device and the detection device. The processing unit can control the brush rotation speed, panel conveying speed, and brush pressure of the panel cleaning device. The detection device performs a preset detection operation on a panel and generates detection information. After receiving the detection information, the processing unit can execute the panel cleaning parameter adjustment method. The process includes the following steps: A first condition judgment step: Based on the test information, determine whether a first defect rate is greater than a first preset value; the first defect rate refers to the total number of panels judged as first-defective products, divided by the total number of panels already inspected; the total number of first-defective products refers to the total number of panels judged as defective by the inspected equipment according to a first preset inspection item. A second condition judgment step: Based on the test information, determine whether a second defect rate is greater than a second preset value; the second defect rate refers to the total number of panels judged as second-defective products. The total number of second-defect panels is divided by the total number of inspected panels. The total number of second-defect panels refers to the total number of panels judged as defective by the inspected equipment according to a second preset inspection item. The first preset inspection item is different from the second preset inspection item. If, in the first condition judgment step, it is determined that the first defect rate is greater than the first preset value, and in the second condition judgment step, it is determined that the second defect rate is greater than the second preset value, then the following steps are performed: A first adjustment step: Increase the panel conveying speed by one preset conveying speed unit. In the defect judgment step, if the first defect rate is determined to be greater than the first preset value, and in the second condition judgment step, the second defect rate is determined to be less than or equal to the second preset value, then the following steps are performed: a second adjustment step: increase the brush speed by one preset brush speed unit; wherein, if in the first condition judgment step, the first defect rate is determined to be less than or equal to the first preset value, and in the second condition judgment step, the second defect rate is determined to be greater than the second preset value, then the following steps are performed: a third adjustment step: increase the brush pressure by one preset pressure unit.

One embodiment of the present invention discloses a panel processing system, comprising: the processing device, panel cleaning equipment, and detection equipment described above; the processing device, after receiving detection information transmitted by the detection equipment, is capable of executing the panel cleaning parameter adjustment method of the present invention; the panel processing system further comprises: a feeding device electrically connected to the processing device, the feeding device being used to convey panels; wherein, the panel cleaning equipment comprises: a conveying platform for receiving panels conveyed by the feeding device; the processing device is capable of controlling one side of the panel conveyed by the conveying platform. The system includes: a panel conveying speed; multiple brushes disposed on at least one side of a conveying platform; a processing device capable of controlling the brush rotation speed; at least one brush control device connected to the multiple brushes, the processing device controlling the brush control device to change the brush pressure applied by the multiple brushes to the panel disposed on the conveying platform; a spraying device for spraying a preset liquid onto the panel; and a detection device for receiving the panel through the panel cleaning device, and for performing a preset detection operation on the panel and generating detection information.

In summary, the panel cleaning parameter adjustment method of this invention, through the design of a first condition judgment step, a second condition judgment step, a first adjustment step, a second adjustment step, and a third adjustment step, can adjust at least one of the panel conveying speed, brush rotation speed, and brush downward pressure in the panel cleaning equipment in real time, thereby effectively reducing the wear rate of the panel in the panel cleaning equipment. The panel processing system of this invention, through its processing device, can execute the panel cleaning parameter adjustment method of this invention to control at least one of the panel conveying speed, brush rotation speed, and brush downward pressure in the panel cleaning equipment, thereby effectively reducing the wear rate of the panel in the panel cleaning equipment.

The panel processing system 100 of this invention includes a processing device 1, a feeding device 2, a panel cleaning device 3, and a detection device 4. The processing device 1 may include, for example, a computer or server. The processing device 1 can be used to control the feeding device 2, the panel cleaning device 3, and the detection device 4, but is not limited thereto. In different embodiments, the panel processing system 100 may also include multiple processing devices, where one processing device 1 controls the panel cleaning device 3, and the other processing devices are used to control the feeding device 2 and the detection device 4 respectively, and the multiple processing devices can exchange information with each other.

The feeding device 2 is electrically connected to the processing device 1, and the feeding device 2 is used to convey a panel A. In one embodiment, the feeding device 2 may simply be used to convey the panel A into the panel cleaning device 3.

The panel cleaning equipment 3 is electrically connected to the processing device 1. The panel cleaning equipment 3 includes: a conveying platform 31, multiple brushes (upper brush 32 and lower brush 33), multiple brush control devices (upper brush control device 34 and lower brush control device 35), and a spraying device 36. The number and placement of the brushes in the panel cleaning equipment 3 can be designed according to actual needs; the figure shows only one example. The number of brush control devices in the panel cleaning equipment 3 can also be varied according to actual needs and is not limited to what is shown in the figure.

The conveying platform 31 is used to receive the panel A fed by the feeding device 2. The conveying platform 31 includes, for example, a processor 310, a drive unit 311, and multiple rollers 312. The processor 310 is electrically connected to the drive unit 311 and is also electrically connected to the processing device 1. The drive unit 311 is mechanically connected to the multiple rollers 312. The drive unit 311 includes, for example, a servo motor. The processing device 1 can control the drive unit 311 via the processor 310 to change the rotation speed of the multiple rollers 312, thereby changing the panel conveying speed. The processor 310 can transmit the panel conveying speed 3101 to the processing device 1, or the processing device 1 can read the panel conveying speed 3101 via the processor 310. Multiple rollers 312 are used to carry and transport panel A.

The multiple brushes can be divided into multiple upper brushes 32 and multiple lower brushes 33. The multiple upper brushes 32 are disposed above the conveyor platform 31. The multiple lower brushes 33 can be arranged between multiple rollers 312. The multiple upper brushes 32 and multiple lower brushes 33 are used to clean the top and bottom surfaces of the panel A located on the conveyor platform 31, respectively. In one embodiment, the panel cleaning device 3 may only include multiple upper brushes 32. In one embodiment, the panel cleaning device 3 may only include multiple lower brushes 33.

The multiple brush control devices can be divided into an upper brush control device 34 and a lower brush control device 35. The upper brush control device 34 is connected to multiple upper brushes 32 and is electrically connected to the processing device 1. The processing device 1 can control the upper brush control device 34 to change the amount of pressure applied by the multiple upper brushes 32 to the panel A located on the conveyor platform 31. The processing device 1 can also control the upper brush control device 34 to change the brush rotation speed of the multiple upper brushes 32.

The lower brush control device 35 is connected to a plurality of lower brushes 33 and is electrically connected to the processing device 1. The processing device 1 can control the lower brush control device 35 to change the amount of pressure applied by the plurality of lower brushes 33 to the panel A located below the conveyor platform 31. The processing device 1 can control the lower brush control device 35 to change the brush rotation speed of the plurality of lower brushes 33.

In practical applications, the upper brush control device 34 and the lower brush control device 35 may each include a servo slide rail 341 and 351, respectively. One end of the upper brush 32 and the lower brush 33 may be connected to the slider of the servo slide rail 341 and 351, and the processing device 1 is electrically connected to the servo slide rail 341 and 351. The processing device 1 can control the slider of the servo slide rail 341 and 351 to change the brush pressure of the upper brush 32 and the lower brush 33.

In one embodiment, the processing device 1 may control the brush pressing amount of each upper brush 32, which is approximately the same as the brush pressing amount of each lower brush 33. In another embodiment, the processing device 1 may control the brush pressing amount of each upper brush 32, which is different from the brush pressing amount of each lower brush 33.

In one embodiment, the processing device 1 may only control the brush pressing amount of each upper brush 32, while the processing device 1 does not control the brush pressing amount of each lower brush 33. In one embodiment, the processing device 1 may only control the brush pressing amount of each lower brush 33, while the processing device 1 does not control the brush pressing amount of each upper brush 32.

At the other end of the upper brush 32 and the lower brush 33, a servo motor 342 of the upper brush control device 34 and a servo motor 352 of the lower brush control device 35 can be respectively connected. The processing device 1 is electrically connected to the servo motors 342 and 352, and the processing device 1 can change the brush speed of the upper brush 32 and the brush speed of the lower brush 33 by controlling the servo motors 342 and 352.

In practical applications, the upper brush control device 34 can transmit the upper brush rotation speed 34A and the upper brush downward pressure 34B to the processing device 1, and the lower brush control device 35 can transmit the lower brush rotation speed 35A and the brush downward pressure 35B to the processing device 1. Alternatively, the processing device 1 can read the upper brush rotation speed 34A and the upper brush downward pressure 34B of the upper brush control device 34, and the processing device 1 can read the lower brush rotation speed 35A and the brush downward pressure 35B of the lower brush control device 35.

In one embodiment, the brush rotation speed of each upper brush 32 can be approximately the same, and the brush rotation speed of each lower brush 33 can be approximately the same. In one embodiment, the brush rotation speed of each upper brush 32 and the brush rotation speed of each lower brush 33 can be approximately the same. In one embodiment, the brush rotation speed of each upper brush 32 is approximately the same, and the brush rotation speed of each lower brush 33 is approximately the same, but the brush rotation speed of each upper brush 32 is different from the brush rotation speed of each lower brush 33.

In one embodiment, the processing device 1 may control the brush speed of each upper brush 32 and also control the brush speed of each lower brush 33. In another embodiment, the processing device 1 may only control the brush speed of each upper brush 32, and not control the brush speed of each lower brush 33. In different embodiments, the processing device 1 may only control the brush speed of each lower brush 33, and not control the brush speed of each upper brush 32.

It is worth mentioning that, in practice, to avoid damage to panel A caused by the upper brush 32 or the lower brush 33, the brush speeds of the upper brush 32 and the lower brush 33, after adjustment by the processing device 1, are both within a corresponding preset brush speed range. Similarly, the brush pressure of the upper brush 32 and the brush pressure of the lower brush 33, after adjustment by the processing device 1, are both within a corresponding preset brush pressure range. Furthermore, the panel conveying speed adjusted by the processing device 1 is also within a corresponding preset panel conveying speed range. The preset brush speed range, preset brush pressure range, and preset panel conveying range can be pre-stored in the processing device 1.

In practical applications, for the same panel, the greater the pressure applied by the brush, the faster the brush speed, or the slower the panel conveying speed, the easier it is for the brush to damage the panel. Furthermore, different panels can withstand different brush speeds, brush pressures, and panel conveying speeds. Therefore, the preset brush speed range, preset brush pressure range, and preset panel conveying range can be designed based on the type of panel and the actual situation, and are not limited here.

A spraying device 36 is mounted above the conveying platform 31. The spraying device 36 is used to spray a preset liquid onto panel A. The preset liquid can be any liquid used to clean the panel, such as purified water (DI water), and can be selected according to actual needs; there is no limitation thereto. The spraying device 36 may, for example, include multiple spray nozzles, each of which sprays the preset liquid onto panel A. In one embodiment, the spraying device 36 may spray the preset liquid onto both sides of panel A simultaneously. In another embodiment, the spraying device 36 may spray the preset liquid onto only one side of panel A.

The detection device 4 is electrically connected to the processing device 1. The detection device 4 is used to receive the panel A through the panel cleaning device 3, and the detection device 4 can perform a preset detection operation on the panel A and generate detection information 41. For example, the preset detection operation may include panel surface scratch detection, panel surface dirt detection, roller mark detection, etc.

The processing device 1 can, based on a first comparison result and a second comparison result, increase the panel conveying speed by a preset conveying speed unit, or increase the brush rotation speed by a preset brush rotation speed unit, or increase the brush pressure by a preset pressure unit. The first comparison result is the processing device 1 comparing a pre-stored first preset value 10 with a first preset inspection item of panel A in the inspection information 41 to obtain a first defect rate. The second comparison result is the processing device 1 comparing a pre-stored second preset value 11 with a second predicted inspection item of panel A to obtain a second defect rate. The first preset inspection item may be detecting whether the panel surface is dirty, and the second preset inspection item may be detecting whether the panel surface is scratched. The details of how the processing device 1 adjusts the panel conveying speed, brush rotation speed and brush pressure according to the first comparison result and the second comparison result will be described later.

In practice, the minimum adjustable speed unit of a brush varies depending on the type and model of the driver (e.g., servo motor) to which each brush is connected. Therefore, a preset brush speed unit can be designed based on actual requirements. Similarly, a preset conveyor speed unit and a preset pressure unit can be designed based on actual requirements. For example, a preset brush speed unit could be 100 revolutions per minute (rpm), a preset conveyor speed unit could be 0.1 meters per minute (m/min), and a preset pressure unit could be 0.1 millimeters (mm).

In one embodiment, the processing device 1 may also be connected to an input device 5 (e.g., a touch screen, keyboard, mouse, etc.), allowing the user to set a first preset value 10 and a second preset value 11 by operating the input device 5. In different embodiments, the processing device 1 may be able to obtain the first preset value 10 and the second preset value 11 from an external electronic device (e.g., a server, computer, tablet computer, smartphone, etc.) via wired or wireless means.

In one embodiment, the processing device 1 can obtain a feeding speed 21 at which the feeding device 2 feeds panel A into the panel cleaning device 3, and the processing device 1 can adjust the panel conveying speed based on a comparison result of a preset conveying speed 12 and the feeding speed 21. For example, when the feeding speed 21 is greater than the preset conveying speed 12, the processing device 1 can reduce the panel conveying speed to increase the time the panel stays in the panel cleaning device 3, thereby allowing the panel to be cleaned more thoroughly. Conversely, when the feeding speed 21 is less than the preset conveying speed 12, the processing device 1 can increase the panel conveying speed to increase the time the panel stays in the panel cleaning device, thereby preventing the panel from staying in the panel cleaning device for too long, which would disrupt the overall process.

The preset conveying speed 12 can be pre-stored in the processing device 1. This preset conveying speed can be the average of all the feeding speeds currently received by the processing device 1. For example, each time the feeding device 2 feeds a panel A into the panel cleaning device 3, the processing device 1 receives a feeding speed. Therefore, the preset conveying speed when the processing device 1 receives the Nth feeding speed is the average of the 1st, 2nd, 3rd…N-1th feeding speeds. In practical applications, the panel cleaning device 3 can transmit the panel conveying speed 3101 to the processing device 1, or the processing device 1 can read the panel conveying speed 3101 from the panel cleaning device 3.

In one embodiment, the processing device 1 can obtain the receiving speed of panel A from the feeding device 2 in the panel cleaning equipment 3, and the processing device 1 can adjust the panel conveying speed according to a comparison result of a preset conveying speed and the receiving speed. The preset conveying speed is the total average of all receiving speeds currently received by the processing device 1. For example, the conveying platform 31 may include a detector electrically connected to the processor 310. When panel A is fed into the conveying platform 31 from the feeding device 2, the detector will generate a detection signal, thereby allowing the processor 310 to know that the feeding device 2 has fed a panel A into the panel cleaning equipment 3. The processor 310, in cooperation with the detector, can calculate the material receiving speed and transmit the real-time calculated material receiving speed to the processing device 1. When the processing device receives the material receiving speed for the Nth time, the preset transmission speed is the total average of the material receiving speeds of the 1st, 2nd, 3rd...N-1th material receiving speeds.

In one embodiment, the feeding device 2 may continuously transmit the feeding speed 21 to the processing device 1. In one embodiment, the processing device 1 may continuously read the feeding speed of the feeding device 2. In one embodiment, the panel cleaning device 3 may continuously transmit the feeding speed to the processing device 1. In one embodiment, the processing device 1 may continuously read the feeding speed of the panel cleaning device 3.

In one embodiment, the processing device 1 can also be connected to a formula database 13. The processing device 1 can receive a feed information 22, which includes material data 221. The material data is the data corresponding to panel A currently being fed from the feeding device 2 to the panel cleaning device 3 (e.g., panel model). Based on the feed information 22, the processing device 1 can look up the corresponding preset parameter information 131 in the formula database 13, and based on the preset parameter information 131, the processing device 1 can set the initial panel conveying speed, the initial brush rotation speed, and the initial brush pressure. In other words, each preset parameter information 131 includes a panel conveying speed, a brush rotation speed, and a brush pressure.

There is no limitation on where the processing device 1 obtains the feed information 22. In one embodiment, the feed device 2 can transmit the feed information 22 to the processing device 1, or the processing device 1 can read the feed information 22 from the feed device 2. In one embodiment, the processing device 1 may obtain the feed information 22 from an external electronic device (e.g., a server), or the feed information 22 may be input and stored in the processing device 1 by relevant personnel using an input device (e.g., a keyboard, mouse, touch screen, etc.).

The material input information 22 may include information related to the current panel, such as model, size, type, thickness, and part number, which can be designed according to actual needs. In one embodiment, the formula database 13 may be an external data storage device such as a server or computer. In one embodiment, the formula database 13 may be a database belonging to the processing device 1.

In an embodiment of the panel processing system 100 that includes an input device 5, the input device 5 can also be used to provide the user with information on preset parameters 131 in the recipe database 13. The input device 5 can also be used, for example, to provide the user with information on modifying the current panel conveyor speed, brush speed, and brush pressure. The input device 5 can include, for example, a touchscreen, keyboard, mouse, etc., but is not limited thereto. Of course, in practice, after the processing device 1 receives the modified values transmitted from the input device 5, it will perform a comparison operation to ensure that each modified value falls within the corresponding preset panel conveyor speed range, preset brush speed range, and preset brush pressure range.

As shown in Figures 1, 2, and 5, in practical applications, the panel processing system 100 may also include a display device 6 electrically connected to the processing device 1. The processing device 1 can control the display device 6 to display a setting interface 61. The setting interface 61 may display, for example, real-time panel conveying speed, brush rotation speed, and brush pressure. The setting interface 61 may also have related operation buttons for users to modify the panel conveying speed, brush rotation speed, and brush pressure. In one embodiment, one page of the setting interface 61 may also display the panel conveying speed, brush rotation speed, and brush pressure from the currently corresponding preset parameter information 131.

In one embodiment, the panel processing system 100 may further include a drying device (not shown), which may be located between the panel cleaning device 3 and the inspection device 4. Panel A, delivered from the panel cleaning device 3, can enter the drying device for drying. After passing through the drying device, panel A is then sent to the inspection device 4. The drying device may be, for example, blowing clean gas onto panel A, but is not limited thereto. In different embodiments, the drying device may also be integrated into the panel cleaning device 3.

As described above, the panel processing system 100 of the present invention, through the design of the processing device 1 that can adjust the panel conveying speed, brush rotation speed and brush pressure according to the first comparison result and the second comparison result, allows the panel processing system 100 to automatically and adaptively adjust the panel conveying speed, brush rotation speed and brush pressure during the processing of panel A, thereby significantly reducing the probability of panel A being damaged during the cleaning process.

In addition, since the processing device 1 can adjust the panel conveying speed, brush rotation speed and brush pressure in real time according to the first comparison result and the second comparison result, no human intervention is required during the adjustment process. Therefore, the probability of panel A being damaged during the cleaning process can be minimized.

It is worth mentioning that the panel cleaning device 3 may also include multiple sensors 37, which are used to detect whether panel A exists between multiple brushes and the conveying platform 31. The processing device 1 is electrically connected to the multiple sensors 37 and can receive sensing information 371 from the multiple sensors 37. Before adjusting at least one of the panel conveying speed, brush rotation speed, and brush pressure based on the first comparison result and the second comparison result, the processing device 1 may first obtain the sensing information 371 and determine whether panel A exists between the brushes and the conveying platform 31 based on the sensing information 371. The processing device 1 will only adjust the panel conveying speed, brush rotation speed, and brush pressure when panel A is not found between the brushes and the conveying platform 31.

Please refer to Figure 6, which is a flowchart illustrating the panel cleaning parameter adjustment method of this invention. This panel cleaning parameter adjustment method is applicable to the panel processing system of this invention. The panel processing system includes panel cleaning equipment, detection equipment, and processing devices. For a detailed description of the panel processing system, please refer to the uploaded content; it will not be repeated here.

After receiving the detection information, the processing device can execute the panel cleaning parameter adjustment method. The panel cleaning parameter adjustment method includes the following steps:

First condition judgment step S1: Based on the test information, determine whether the first defect rate is greater than a first preset value;

If the first defect rate is determined to be greater than the first preset value, then the following steps are performed:

Second condition judgment step S2: Based on the detection information, determine whether a second defect rate is greater than a second preset value; if the second defect rate is greater than the second preset value, then execute a first adjustment step S3; if the second defect rate is less than the second preset value, then execute a second adjustment step S4.

The first adjustment step S3: Increase the panel transmission speed by one preset transmission speed unit.

The second adjustment step S4: Increase the brush speed by one preset brush speed unit.

If, in the first condition determination step S1, it is determined that the first defect rate is not greater than (i.e., less than or equal to) the first preset value, then the second condition determination step S2A is executed: based on the detection information, it is determined whether a second defect rate of the panel is greater than a second preset value; if it is determined to be greater than the second preset value, then a third adjustment step S5 is executed; if it is determined to be less than the second preset value, then a maintenance step S6 is executed.

The third adjustment step S5: Increase the brush pressure by one preset pressure unit.

The maintenance step S6: Maintain the current panel conveying speed, maintain the current brush rotation speed, and maintain the current brush pressure. That is, do not adjust the panel conveying speed, do not adjust the preset brush rotation speed, and do not adjust the brush pressure.

The first defect rate refers to the total number of panels identified as first defective products, divided by the total number of panels that have been inspected; the total number of first defective products refers to the total number of panels identified as defective products by the testing equipment according to a first preset inspection item; the second defect rate refers to the total number of panels identified as second defective products, divided by the total number of panels inspected; the total number of second defective products refers to the total number of panels identified as defective products by the testing equipment according to a second preset inspection item; the first preset inspection item is different from the second preset inspection item.

In one practical application, the first preset detection item could be detecting whether the panel is dirty, with a first preset value of 0.01 (i.e., 1%). The second detection item could be detecting whether the panel is scratched, with a second preset value of 0.05 (i.e., 5%). How to detect whether the panel is dirty or scratched is prior art and will not be elaborated here. For example, assuming the testing equipment has performed testing on 100 panels, of which 5 panels (i.e., the aforementioned total number of first defective products) are determined to be first defective products, and 4 of them are determined to be second defective products, then in the first condition determination step S1, the processing device will determine that the first defect rate (i.e., 5%) is greater than the first preset value (i.e., 1%), and in the second condition determination step S2, the processing module will determine that the second defect rate (i.e., 4%) is greater than the second preset value (i.e., 5%), and then the processing device will execute the first adjustment step S3.

As described above, the processing device will perform the first adjustment step S3, the second adjustment step S4, the third adjustment step S5, or the maintenance step S6 based on the comparison results of the first defect rate and the first preset value, and the comparison results of the second defect rate and the second preset value. This design effectively reduces the damage rate of panels in the panel cleaning equipment, and because the processing device can control the panel cleaning equipment in real time, it effectively reduces the probability of a large number of panels being scrapped.

It should be noted that, in the above description, the processing device 1 first executes the first condition judgment step S1, and then, based on the judgment result, continues to execute the second condition judgment step S2 or the second condition judgment step S2A. However, in different embodiments, when processing device 1 performs the first condition judgment step S1, the final judgment result can be recorded as a first comparison result (for example, it can be stored as a Bollinger value); when processing device 1 performs the second condition judgment step S2, the final judgment result can be recorded as a second comparison result (for example, it can be stored as a Bollinger value); then, the processing device can directly use the first comparison result and the second comparison result to decide whether to continue performing the first adjustment step S3, the second adjustment step S4, the third adjustment step S5, or the maintenance step S6.

In practical applications, in order to avoid damage to the surface of panel A caused by the adjusted brush speed, brush pressure, or panel conveying speed of processing device 1, the increased panel conveying speed in the first adjustment step S3 is within a preset panel conveying speed range; the increased brush speed in the second adjustment step S4 is within a preset brush speed range; and the increased brush pressure in the third adjustment step S5 is within a preset brush pressure range.

In one embodiment, the panel cleaning device 3 includes multiple upper brushes 32 and multiple lower brushes 33. In the second adjustment step S4, the processing device 1 may increase the brush speed of each upper brush 32 by a preset speed unit, or increase the brush speed of each lower brush 33 by a preset speed unit.

In one embodiment, the panel cleaning device 3 includes multiple upper brushes 32 and multiple lower brushes 33. In the second adjustment step S4, the processing device 1 may increase the brush speed of each upper brush 32 by a preset speed unit and increase the brush speed of each lower brush 33 by a preset speed unit.

In an embodiment where the panel cleaning device 3 includes only multiple upper brushes 32, in the second adjustment step S4, the processing device 1 simply increases the brush speed of each upper brush 32 by one preset speed unit. In an embodiment where the panel cleaning device 3 includes only multiple lower brushes 33, in the second adjustment step S4, the processing device 1 simply increases the brush speed of each lower brush 33 by one preset speed unit.

In one embodiment, the panel cleaning device 3 includes multiple upper brushes 32 and multiple lower brushes 33. In the third adjustment step S5, the processing device 1 may increase the brush pressure of each upper brush 32 by a preset pressure unit, or increase the brush pressure of each lower brush 33 by a preset pressure unit.

In one embodiment, the panel cleaning device 3 includes multiple upper brushes 32 and multiple lower brushes 33. In the third adjustment step S5, the processing device 1 may increase the brush pressure of each upper brush 32 by a preset pressure unit and increase the brush pressure of each lower brush 33 by a preset pressure unit.

In an embodiment where the panel cleaning device 3 includes only multiple upper brushes 32, in the third adjustment step S5, the processing device 1 simply increases the brush pressure of each upper brush 32 by one preset pressure unit.
