Description
Technical Field
[0001] This invention belongs to the field of liquid crystal panel technology, and specifically relates to an automatic edge detection and redesign method, device, electronic device and medium based on MMG. Background Technology
[0002] With the improvement of people's living standards, large-size LCD screens are becoming increasingly popular among consumers, and the replacement of small LCD screens with large ones has become a trend. Therefore, the production of large-size LCD panels has a good market and development momentum. The traditional production method is to bond two glass substrates together to form the motherboard of the LCD panel. The motherboard is then laid out and cut into multiple independent LCD panels. However, due to the limitations of glass substrate size, producing large-size LCD panels of a single size using glass substrates results in low utilization of the glass substrates, leading to waste and high production costs, thus limiting its market development.
[0003] Currently, multi-mounted group (MMG) technology is used to improve this defect. It combines two different sizes of LCD panels on a single glass substrate, which can improve the utilization rate of the glass substrate. After multi-mounting, two sizes of LCD panels will be produced.
[0004] After the LCD panel is cut, the edges of the LCD panel need to be inspected. In the prior art, the edge inspection device is first moved to the initial position, and then the LCD panel to be inspected is moved to the inspection platform by the loading and transfer device. The inspection platform clamps and fixes it, and then the edge inspection device is moved to inspect the long side of the LCD panel. After the inspection is completed, the edge inspection device returns to the initial position, the inspection platform rotates 90 degrees, and the edge inspection device is moved to inspect the short side of the LCD panel.
[0005] The existing technology has at least the following problems:
[0006] 1. In the overlay cutting scheme, the edge inspection device needs to frequently switch positioning positions according to the two LCD panel sizes, which greatly increases the waiting time for edge inspection and affects the production efficiency of LCD panels. Summary of the Invention
[0007] The technical problem to be solved by the present invention is to provide an automatic edge detection and switching method, device, equipment and medium based on MMG, which aims to solve the technical problem that in the existing technology, the edge inspection device needs to frequently switch the positioning position according to two LCD panel sizes in the overlay cutting scheme, which greatly increases the waiting time of edge inspection and affects the production efficiency of LCD panels.
[0008] The technical solution of this invention to solve the above-mentioned technical problems is as follows: an automatic shape-changing method based on MMG edge detection, the method comprising:
[0009] S1, respectively configures the corresponding MMG formula for two types of liquid crystal panels to be tested that are mixed and integrated on the same glass substrate but have different sizes;
[0010] S2, obtain the registration information of the border inspection unit, wherein the registration information of the border inspection unit is used to indicate whether there is an LCD panel to be inspected at the workstation of the border inspection unit; if it is determined according to the registration information of the border inspection unit that there is no LCD panel to be inspected at the workstation of the border inspection unit, then execute S3; if it is determined according to the registration information of the border inspection unit that there is an LCD panel to be inspected at the workstation of the border inspection unit, then execute S4.
[0011] S3: Obtain the registration information of the loading unit located upstream of the border inspection unit. The registration information of the loading unit is used to indicate whether there is a liquid crystal panel to be tested at the station of the loading unit. If it is determined according to the registration information of the loading unit that there is no liquid crystal panel to be tested at the station of the loading unit, then the border inspection unit is suspended. If it is determined according to the registration information of the loading unit that there is a liquid crystal panel to be tested at the station of the loading unit, then obtain the MMG information of the liquid crystal panel to be tested at the station of the loading unit, wherein the MMG information is used to indicate the type of liquid crystal panel to be tested. And according to the MMG information of the liquid crystal panel to be tested at the station of the loading unit, assign the corresponding MMG formula to the border inspection unit, so that the border inspection unit operates according to the assigned MMG formula.
[0012] S4, lock the current MMG formula of the border inspection unit, so that the border inspection unit operates according to the current MMG formula.
[0013] The beneficial effects of this invention are as follows: If there is no LCD panel to be inspected on the edge inspection unit, the invention obtains the MMG information of the LCD panel to be inspected on the workstation of the loading unit, and assigns the MMG formula corresponding to the MMG information to the edge inspection unit, so that the edge inspection unit performs the operation according to the assigned MMG formula; by performing the operation according to the MMG formula of the loading unit, the edge inspection unit obtains the operation information of the edge inspection unit in advance, shortens the changeover time, and improves the factory efficiency of LCD panel edge inspection during tailing.
[0014] Furthermore, in S1 above, the MMG formula stores position parameter information of the action device of the edge inspection unit when the edge inspection unit performs its operation. The action device includes: an auxiliary platform, a detection platform, an alignment device, and a blocking device. The position parameter information includes: auxiliary detection position parameters of the long side of the auxiliary platform, auxiliary detection position parameters of the long side of the detection platform, auxiliary detection position parameters of the short side of the auxiliary platform, auxiliary detection position parameters of the short side of the detection platform, loading alignment position parameters of the alignment device, and loading blocking position parameters of the blocking device. The MMG formula also stores the number of vacuum suction cups required for the long side and the number of vacuum suction cups required for the short side of the liquid crystal panel to be inspected.
[0015] The beneficial effects of adopting the above-mentioned further solution are: it specifically defines the position parameter information of the action device of the border inspection unit when the border inspection unit performs its actions, so that the action device can move to a fixed position during the inspection process, ensuring the accuracy and efficiency of the inspection.
[0016] Furthermore, in S3 above, the method for obtaining the MMG information of the LCD panel to be tested on the workstation of the feeding unit is to scan a QR code. The QR code is set on the LCD panel to be tested, and the feeding unit is equipped with an image recognition module. The MMG information of the LCD panel to be tested is obtained from the QR code through the image recognition module.
[0017] The beneficial effects of adopting the above-mentioned further solution are: the present invention sets a camera on the feeding unit to acquire the QR code on the liquid crystal panel. The QR code is linked to the MMG information of the liquid crystal panel. The MMG information is acquired wirelessly through the QR code, which not only ensures the security of the acquired information, but also ensures the accuracy of the acquired information.
[0018] Furthermore, in S3 above, after the corresponding MMG formula is assigned to the border inspection unit, the action device in the border inspection unit is prepared to perform actions in advance according to the position parameter information in the assigned MMG formula.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the action device of the present invention prepares for action in advance based on position parameter information, thereby shortening the detection time.
[0020] Furthermore, the specific process by which the border inspection unit in S3 operates according to the assigned MMG formula is as follows:
[0021] S3.1, Obtain and read the MMG recipe;
[0022] S3.2, control the detection platform to move to the long side detection position in advance according to the long side detection position parameter, and control the auxiliary platform to move from the standby position to the long side auxiliary detection position in advance according to the long side auxiliary detection position parameter;
[0023] S3.3 After the LCD panel to be tested moves to the loading roller table of the edge inspection unit and stops, the centering device on both sides of the loading roller table is controlled to move to the loading centering position according to the loading centering position parameter, so that the LCD panel to be tested is located at the center of the loading roller table.
[0024] S3.4 During the process of the LCD panel to be tested moving to the station of the testing platform, the blocking device is controlled to move to the loading blocking position in advance according to the loading blocking position parameter, so that after the LCD panel to be tested moves to the station of the testing platform, the center of the LCD panel to be tested coincides with the center of the station of the testing platform.
[0025] S3.5 After the LCD panel to be tested is moved to the work station of the testing platform, the testing platform located at the long side testing position is controlled to perform vacuum adsorption on the middle part of the LCD panel to be tested, and the auxiliary platform located at the long side auxiliary testing position is controlled to drive the corresponding number of vacuum suction cups to perform vacuum adsorption on the long side of the LCD panel to be tested according to the number of vacuum suction cups required for the long side of the LCD panel to be tested.
[0026] S3.6 When the vacuum chuck performs vacuum adsorption on the long side of the LCD panel to be tested and there is no abnormality in the vacuum adsorption, the detection platform is controlled to perform long side detection on the LCD panel to be tested. After the long side detection is completed, the auxiliary platform is controlled to perform vacuum destruction on the vacuum chuck, so that the vacuum chuck detaches from the long side of the LCD panel to be tested.
[0027] S3.7, control the detection platform to rise and rotate 90 degrees, and control the auxiliary platform to move to the standby position;
[0028] S3.8, control the detection platform to move to the short side detection position according to the short side detection position parameter, and control the auxiliary platform to move from the standby position to the short side auxiliary detection position according to the short side auxiliary detection position parameter;
[0029] S3.9, control the detection platform located at the short side detection position to perform vacuum adsorption on the middle part of the liquid crystal panel to be tested, and control the auxiliary platform located at the short side auxiliary detection position to drive a corresponding number of vacuum suction cups to perform vacuum adsorption on the short side of the liquid crystal panel to be tested according to the number of vacuum suction cups required for the short side of the liquid crystal panel to be tested.
[0030] S3.10, after the vacuum chuck performs vacuum adsorption on the short side of the LCD panel to be tested and there is no abnormality in the vacuum adsorption, the control platform performs short side detection on the LCD panel to be tested. After the short side detection is completed, the control platform performs vacuum destruction on the vacuum chuck, so that the vacuum chuck detaches from the short side of the LCD panel to be tested.
[0031] The beneficial effects of adopting the above-mentioned further solution are as follows: When the LCD panel to be inspected is being changed, the edge inspection unit obtains the MMG formula of the LCD panel to be inspected in advance. Then, according to the MMG formula, the centering device, blocking device, inspection platform, and auxiliary platform are moved to the workstation in advance. When the LCD panel to be inspected flows in from the feeding unit, the centering device moves the LCD panel to be inspected to the center of the feeding roller table, and then it is transferred by the feeding ARM to avoid the LCD panel to be inspected being crushed during the transfer process. The blocking device ensures that the center of the LCD panel is located at the center of the inspection platform, ensuring that the center of the LCD panel to be inspected coincides with the center of the inspection platform, which facilitates the subsequent edge inspection work. Furthermore, the advance movement of the inspection platform and auxiliary platform to the inspection station ensures the rapid progress of the edge inspection work.
[0032] Furthermore, the aforementioned preset pressure threshold range for the vacuum suction cup is used to drive the vacuum suction cup to adsorb the edge of the LCD panel to be tested. If the pressure value of the vacuum suction cup is not within the pressure threshold range, an alarm will be triggered and the edge detection work will be stopped.
[0033] The beneficial effect of adopting the above-mentioned further solution is that the present invention sets a pressure test gauge on the vacuum suction cup, and only starts edge detection when the adsorption is normal, thus avoiding errors that could damage the liquid crystal panel during subsequent edge detection work.
[0034] Furthermore, during the operation of the aforementioned border inspection unit according to the assigned MMG formula, it supports first performing short-side detection of the LCD panel under test, and then performing long-side detection of the LCD panel under test.
[0035] The beneficial effect of adopting the above-mentioned further solution is that the detection order can be set according to needs, making edge detection more flexible.
[0036] Secondly, to solve the above-mentioned technical problems, the present invention also provides an automatic edge detection and shape-changing device based on MMG, comprising:
[0037] MMG formulation module: used to configure the corresponding MMG formulation for two types of LCD panels to be tested that are integrated on the same glass substrate but have different sizes;
[0038] Registration information acquisition module: used to acquire registration information of border inspection units, wherein the registration information of border inspection units is used to indicate whether there is an LCD panel to be tested at the workstation of the border inspection unit; and to determine whether there is an LCD panel to be tested at the workstation of the border inspection unit based on the registration information of the border inspection unit.
[0039] The MMG formula assignment module is used to: acquire the registration information of the loading unit located upstream of the border inspection unit when the registration information acquisition module determines that there is no LCD panel to be tested at the station of the border inspection unit; the registration information of the loading unit is used to indicate whether there is an LCD panel to be tested at the station of the loading unit; if it is determined according to the registration information of the loading unit that there is no LCD panel to be tested at the station of the loading unit, then the border inspection unit is suspended; if it is determined according to the registration information of the loading unit that there is an LCD panel to be tested at the station of the loading unit, then the MMG information of the LCD panel to be tested at the station of the loading unit is acquired, wherein the MMG information is used to indicate the type of LCD panel to be tested; and according to the MMG information of the LCD panel to be tested at the station of the loading unit, assign the corresponding MMG formula to the border inspection unit, so that the border inspection unit operates according to the assigned MMG formula.
[0040] Locking module: When the registration information acquisition module determines that there is an LCD panel to be tested at the workstation of the border inspection unit, the module locks the current MMG formula of the border inspection unit, so that the border inspection unit operates according to the current MMG formula.
[0041] Thirdly, in order to solve the above-mentioned technical problems, the present invention also provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor.

[0043] Additional aspects and advantages of this application will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of this application. Attached Figure Description

[0048] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0049] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.
[0050] This invention provides a possible implementation, such as... Figure 1 The diagram illustrates a flowchart of an automatic shape-changing method based on MMG edge detection, which may include the following steps:
[0051] S1, respectively configures the corresponding MMG formula for two types of liquid crystal panels to be tested that are mixed and integrated on the same glass substrate but have different sizes;
[0052] S2, obtain the registration information of the border inspection unit, wherein the registration information of the border inspection unit is used to indicate whether there is an LCD panel to be inspected at the workstation of the border inspection unit; if it is determined according to the registration information of the border inspection unit that there is no LCD panel to be inspected at the workstation of the border inspection unit, then execute S3; if it is determined according to the registration information of the border inspection unit that there is an LCD panel to be inspected at the workstation of the border inspection unit, then execute S4.
[0053] S3: Obtain the registration information of the loading unit located upstream of the border inspection unit. The registration information of the loading unit is used to indicate whether there is a liquid crystal panel to be tested at the station of the loading unit. If it is determined according to the registration information of the loading unit that there is no liquid crystal panel to be tested at the station of the loading unit, then the border inspection unit is suspended. If it is determined according to the registration information of the loading unit that there is a liquid crystal panel to be tested at the station of the loading unit, then obtain the MMG information of the liquid crystal panel to be tested at the station of the loading unit, wherein the MMG information is used to indicate the type of liquid crystal panel to be tested. And according to the MMG information of the liquid crystal panel to be tested at the station of the loading unit, assign the corresponding MMG formula to the border inspection unit, so that the border inspection unit operates according to the assigned MMG formula.
[0054] S4, lock the current MMG formula of the border inspection unit, so that the border inspection unit operates according to the current MMG formula.
[0055] In this invention, if there is no LCD panel to be inspected on the edge inspection unit, the MMG information of the LCD panel to be inspected on the loading unit is obtained, and the MMG formula corresponding to the MMG information is assigned to the edge inspection unit, so that the edge inspection unit performs the operation according to the assigned MMG formula. By performing the operation according to the MMG formula of the loading unit, the edge inspection unit obtains the operation information of the edge inspection unit in advance, shortens the changeover time, and improves the factory efficiency of LCD panel edge inspection during tailing.
[0056] In the event of machine malfunction or power failure and restart, the system first checks whether the border inspection unit has registration information upon power-on. If registration information is found, it indicates that there is an LCD panel on the border inspection unit. Then, the edge detection work continues according to the MMG formula of the current LCD panel.
[0057] Optionally, in S1, the MMG formula stores position parameter information of the action device of the edge inspection unit when the edge inspection unit performs its operation. The action device includes: an auxiliary platform, a detection platform, an alignment device, and a blocking device. The position parameter information includes: auxiliary detection position parameters of the long side of the auxiliary platform, auxiliary detection position parameters of the long side of the detection platform, auxiliary detection position parameters of the short side of the auxiliary platform, detection position parameters of the short side of the detection platform, loading alignment position parameters of the alignment device, and loading blocking position parameters of the blocking device. The MMG formula also stores the number of vacuum suction cups required for the long side and the number of vacuum suction cups required for the short side of the liquid crystal panel to be inspected.
[0058] Specifically, the position parameter information of the action device of the border inspection unit is defined when the border inspection unit performs its actions, so that the action device can move to a fixed position during the inspection process, ensuring the accuracy and efficiency of the inspection.
[0059] In this embodiment, the two LCD panel sizes are 10 inches and 20 inches. 10 inches refers to a diagonal length of 10 inches, which is equal to 25.4 cm. In a 16:9 aspect ratio, the length and width of a 10-inch LCD panel are approximately 22.14 cm and 12.45 cm, respectively; in a 16:10 aspect ratio, the length and width are approximately 21.54 cm and 12.12 cm, respectively; and in a 4:3 aspect ratio, the length and width are approximately 19.7 cm and 14.8 cm, respectively. Similarly, a 20-inch LCD panel refers to an LCD panel with a diagonal length of 20 inches. The positional parameters for the two sizes are different. Specifically, the loading centering position parameters refer to the following: When the LCD panel to be tested flows in from upstream through the loading roller table, it may shift left or right, requiring a centering device for correction. This is divided into a left-side centering device and a right-side centering device. After the LCD panel stops on the loading roller table, the left-side and right-side centering devices move from the standby position to the centering position, pushing the LCD panel to the exact center. Different sized LCD panels have different centering positions. If the centering position is set too small, the LCD panel cannot be pushed to the exact center; if the centering position is set too large, the LCD panel will be crushed. Therefore, it is necessary to store the feeding centering position parameters and change the type according to the size of the LCD panel.
[0060] The loading obstruction position parameters specifically refer to ensuring center alignment when the LCD panel is transported to the inspection platform. Otherwise, during inspection and imaging, one side will be exposed too much while the other side is exposed too little. These parameters guarantee center alignment when the LCD panel moves to the inspection platform. Similarly, different sizes have different center positions, requiring adjustment of the obstruction device to ensure the center of the LCD panel coincides with the center of the inspection platform.
[0061] Optional. In S3, the method for obtaining the MMG information of the LCD panel to be tested on the workstation of the feeding unit is to scan a QR code. The QR code is set on the LCD panel to be tested, and the feeding unit is equipped with an image recognition module. The MMG information of the LCD panel to be tested is obtained from the QR code through the image recognition module.
[0062] This invention features a camera mounted on the feeding unit to capture a QR code on the LCD panel. This QR code links to the LCD panel's MMG (Multi-Dimensional Gauge) information. Wirelessly acquiring the MMG information via the QR code ensures both security and accuracy. Besides scanning the QR code, this invention can also acquire the MMG information via network transmission from upstream equipment. The upstream equipment transmits the MMG information of the LCD panel simultaneously with its arrival.
[0063] Optionally, in S3, after the corresponding MMG formula is assigned to the border inspection unit, the action device in the border inspection unit is prepared to perform actions in advance according to the position parameter information in the assigned MMG formula.
[0064] In this invention, the action device prepares for action in advance based on position parameter information, thus shortening the detection time.
[0065] Optional, such as Figure 2 As shown, the specific process by which the border inspection unit in S3 performs actions according to the assigned MMG formula is as follows:
[0066] S3.1, Obtain and read the MMG recipe;
[0067] S3.2, control the detection platform to move to the long side detection position in advance according to the long side detection position parameter, and control the auxiliary platform to move from the standby position to the long side auxiliary detection position in advance according to the long side auxiliary detection position parameter;
[0068] S3.3 After the LCD panel to be tested moves to the loading roller table of the edge inspection unit and stops, the centering device on both sides of the loading roller table is controlled to move to the loading centering position according to the loading centering position parameter, so that the LCD panel to be tested is located at the center of the loading roller table.
[0069] S3.4 During the process of the LCD panel to be tested moving to the station of the testing platform, the blocking device is controlled to move to the loading blocking position in advance according to the loading blocking position parameter, so that after the LCD panel to be tested moves to the station of the testing platform, the center of the LCD panel to be tested coincides with the center of the station of the testing platform.
[0070] S3.5 After the LCD panel to be tested is moved to the work station of the testing platform, the testing platform located at the long side testing position is controlled to perform vacuum adsorption on the middle part of the LCD panel to be tested, and the auxiliary platform located at the long side auxiliary testing position is controlled to drive the corresponding number of vacuum suction cups to perform vacuum adsorption on the long side of the LCD panel to be tested according to the number of vacuum suction cups required for the long side of the LCD panel to be tested.
[0071] S3.6 When the vacuum chuck performs vacuum adsorption on the long side of the LCD panel to be tested and there is no abnormality in the vacuum adsorption, the detection platform is controlled to perform long side detection on the LCD panel to be tested. After the long side detection is completed, the auxiliary platform is controlled to perform vacuum destruction on the vacuum chuck, so that the vacuum chuck detaches from the long side of the LCD panel to be tested.
[0072] S3.7, control the detection platform to rise and rotate 90 degrees, and control the auxiliary platform to move to the standby position;
[0073] S3.8, control the detection platform to move to the short side detection position according to the short side detection position parameter, and control the auxiliary platform to move from the standby position to the short side auxiliary detection position according to the short side auxiliary detection position parameter;
[0074] S3.9, control the detection platform located at the short side detection position to perform vacuum adsorption on the middle part of the liquid crystal panel to be tested, and control the auxiliary platform located at the short side auxiliary detection position to drive a corresponding number of vacuum suction cups to perform vacuum adsorption on the short side of the liquid crystal panel to be tested according to the number of vacuum suction cups required for the short side of the liquid crystal panel to be tested.
[0075] S3.10, after the vacuum chuck performs vacuum adsorption on the short side of the LCD panel to be tested and there is no abnormality in the vacuum adsorption, the control platform performs short side detection on the LCD panel to be tested. After the short side detection is completed, the control platform performs vacuum destruction on the vacuum chuck, so that the vacuum chuck detaches from the short side of the LCD panel to be tested.
[0076] In this invention, when the LCD panel to be inspected is being changed, the edge inspection unit obtains the MMG formula of the LCD panel in advance. Then, based on the MMG formula, the centering device, blocking device, inspection platform, and auxiliary platform are moved to the workstation in advance. When the LCD panel to be inspected flows in from the feeding unit, the centering device moves it to the center of the feeding roller table, and then it is transferred by the feeding ARM to prevent the LCD panel from being crushed during transfer. The blocking device ensures that the center of the LCD panel is aligned with the center of the inspection platform, facilitating subsequent edge inspection. Furthermore, the advance movement of the inspection platform and auxiliary platform to the inspection station ensures rapid edge inspection.
[0077] Optionally, a preset pressure threshold range for the vacuum suction cup is provided. After the vacuum suction cup is driven to adsorb the edge of the LCD panel to be tested, if the pressure value of the vacuum suction cup is not within the pressure threshold range, an alarm is triggered and the edge detection work is stopped.
[0078] This invention incorporates a pressure gauge on the vacuum suction cups. Edge detection only begins when adhesion is normal, preventing errors that could damage the LCD panel during subsequent edge detection. Specifically, the edge detection unit arranges the number of vacuum suction cups according to the MMG formula and performs adhesion to the LCD panel. If a vacuum suction cup fails to adhere properly or there is no LCD panel at the corresponding suction cup location, an alarm is triggered, and the edge detection unit stops. Manual repair is then required after the process stops. It's possible that the LCD panel is 10 inches, requiring only 3 vacuum suction cups, but the edge detection unit is using 5 vacuum suction cups (suitable for 20-inch LCD screens), in which case an error message is generated.
[0079] Optionally, during the process of the border inspection unit operating according to the assigned MMG formula, it supports first performing short-side detection of the LCD panel under test, and then performing long-side detection of the LCD panel under test.
[0080] The present invention allows for setting the detection order according to requirements, making edge detection more flexible.
[0081] Based on and Figure 1 Using the same principle as the method shown, this embodiment of the invention also provides an automatic shape-changing device based on MMG edge detection, such as... Figure 3 As shown, it includes:

[0084] The MMG formula assignment module is used to: acquire the registration information of the loading unit located upstream of the border inspection unit when the registration information acquisition module determines that there is no LCD panel to be tested at the station of the border inspection unit; the registration information of the loading unit is used to indicate whether there is an LCD panel to be tested at the station of the loading unit; if it is determined according to the registration information of the loading unit that there is no LCD panel to be tested at the station of the loading unit, then the border inspection unit is suspended; if it is determined according to the registration information of the loading unit that there is an LCD panel to be tested at the station of the loading unit, then the MMG information of the LCD panel to be tested at the station of the loading unit is acquired, wherein the MMG information is used to indicate the type of LCD panel to be tested; and according to the MMG information of the LCD panel to be tested at the station of the loading unit, assign the corresponding MMG formula to the border inspection unit, so that the border inspection unit operates according to the assigned MMG formula.
[0085] Locking module: When the registration information acquisition module determines that there is an LCD panel to be tested at the workstation of the border inspection unit, the module locks the current MMG formula of the border inspection unit, so that the border inspection unit operates according to the current MMG formula.
