For the purpose of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.

The terms "first," "second," and the like, as used in this disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Likewise, the terms "a," "an," or "the" and similar terms do not denote a limitation of quantity, but rather denote the presence of at least one. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items.

"upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

A first aspect of the embodiments of the present disclosure provides a display panel double-sheet production control method capable of solving a system failure problem in a single-sheet state to some extent.

The double-piece production control method of the display panel comprises the following steps:

receiving a double-sheet production request sent by production equipment;

if the loading container to be loaded needs to be subjected to patch operation, determining the piece missing information of the loading container, and controlling the production equipment to carry out patch operation on the loading container according to a preset patch rule and the piece missing information; optionally, the defect information may include, for example, the following information: the information of the position of the missing piece in the loading container (i.e. the situation that the display substrate is missing in the position of the loading container), the related information of the loading container with the missing piece (such as the identity of the loading container and the identity of the display substrate placed in the initial state of the loading container), and the like;

As can be seen from the foregoing embodiments, in the control method for producing double sheets of a display panel provided by the embodiments of the present disclosure, by determining whether a loading container to be loaded needs to be subjected to patch operation, if not, double sheet production is performed, and if so, patch operation is performed according to a preset patch rule, so that the loading container is ensured to be suitable for double sheet production, and further normal performance of double sheet production is ensured.

In this embodiment, the double-sheet production requires that two display panels to be processed can be extracted from the loading container in one processing step, so that two display substrates can be processed at the same time. However, in general, a production line of a display panel includes a plurality of processes that are respectively performed by a plurality of production apparatuses, and after different production apparatuses perform different processes, defective products may occur, and when the defective products are cleaned, a defective portion of the loading container may occur (i.e., a display substrate originally located in the defective portion is cleaned so that the defective portion is left in the defective portion). Therefore, if the position of the missing piece occurs, two display substrates to be processed cannot be extracted at a time, and further, a system fault occurs, so that production equipment cannot operate normally. The patch operation is adopted in the embodiment, so that the defect condition can not influence normal double-sheet production, and the method is important for realizing double-sheet production of the display panel. The patch operation described in this embodiment generally refers to supplementing the display substrate to the missing piece position to solve the problem that the missing piece condition affects normal double-piece production. Specific patch rules may be referenced in the associated description in subsequent embodiments.

It should be further noted that, in one or more embodiments of the present disclosure, the display substrate refers to a semi-finished product or a finished product of a display panel, for example, may be a substrate that is only glass, may also be an intermediate product that has been manufactured with some devices, and may also be a display panel that has been manufactured in some cases. In general, in a process flow of manufacturing a display panel, a semi-finished product formed at each stage may be referred to as a display substrate before a final display panel product is formed.

In addition, a chip failure condition may occur after each process of each production apparatus is completed, and thus each production apparatus may need to check the chip failure condition of the loading container and complete the patch in time before loading the loading container.

The embodiment of the disclosure provides an embodiment of the display panel double-sheet production control method, which can solve the problem of system failure in a single-sheet state to a certain extent. Fig. 1 is a schematic flow chart of an embodiment of a display panel double-sheet production control method according to an embodiment of the disclosure.

As shown in fig. 1, the display panel double-sheet production control method includes:

step 102: and receiving a double-sheet production request sent by the production equipment.

In this step, generally, before the production apparatus enters the production state, a double-sheet production request is sent to the control system for starting the current production process. In this step, the double-sheet production request refers to a request for processing two display substrates simultaneously.

In general, there are many production facilities on a double-sheet production line of display panels. For example, a production apparatus for performing an evaporation process, a production apparatus for performing photoresist coating, a production apparatus for performing an exposure/development process, and the like. When the production equipment corresponding to a certain process is ready, a double-sheet production request can be sent to the control system for starting the current production process.

Step 104: determining whether a patch operation is required to be carried out on the loading container to be loaded according to the double-sheet production request; wherein, the display substrate to be processed is placed in the loading container.

In this step, after the control system receives the two-sheet production request, it is first determined whether a patch operation is required for the loading container to be loaded by the production apparatus. The patch operation refers to patch a missing piece location in the loading container that may affect normal double-piece production.

As an alternative embodiment, as shown in fig. 2A, the loading container 20 includes two rows of placing containers 21/22 arranged in parallel, and the placing containers 21/22 include a plurality of placing cavities 211/221 arranged in a stacked manner, and the placing cavities 211/221 are used for placing the display substrates 30 to be processed.

As an alternative embodiment, the method for controlling the production of the double sheets of the display panel may further include the steps of:

in an initial state, giving unique identification to each display substrate to be processed; alternatively, the unique identifier may be a common identifier (for example, a common tag recognized by human eyes), or may be an identifier that can be read by a reading device, such as a two-dimensional code, a bar code, or the like; optionally, the unique identifier may be disposed at a position of one of four corners of the display substrate, so as to perform reading or identification, and meanwhile, not affect the manufacture of a normal structure of the display substrate;

recording the placement positions and the unique identifiers of the display substrates to be processed placed in the loading container in an initial state, and packaging the placement positions and the unique identifiers of the display substrates to be processed into initial loading information; optionally, before the whole production process starts, a display substrate (which may be a substrate only, usually glass at first) to be processed needs to be placed in each placement cavity of the loading container, and at this time, the position of the placement cavity where each display substrate is placed in the loading container is recorded, and meanwhile, corresponding unique identifiers are recorded, so that the unique identifiers can be in one-to-one correspondence with the placement positions;

determining unique identifiers of all display substrates to be processed placed in the loading container to be loaded; optionally, after a certain production process finishes processing the display substrate, before placing the display substrate in a corresponding loading container, identifying the unique identifier of the display substrate and placing the unique identifier in a corresponding position of the initial loading container;

determining current loading information of the loading container to be loaded according to the unique identification; optionally, after obtaining the unique identifier of each display substrate of the loading container to be loaded, the current loading information of the loading container to be loaded, that is, which positions are placed with the display substrates and the unique identifier of each display substrate, can be obtained statistically;

determining the defect information in the loading container to be loaded according to the current loading information and the initial loading information; optionally, because the previous step counts the unique identifier of the display substrate placed in the loading container, comparing the unique identifier collected before processing with the list by calling the loading information recorded with each unique identifier of the display substrate originally placed in the loading container, and counting the missing piece information in the loading container, wherein the missing piece information comprises the missing piece position; optionally, in some cases, for example, when the current loading container has not had a missing piece after the previous steps, and when the current loading container has a missing piece after the current step is finished (i.e. the missing piece occurs for the first time), the current loading information may be compared with the initial loading information to determine missing piece information; in other cases, for example, when a defect condition has occurred in a previous process, the current loading information needs to be compared with the loading information obtained after the previous process is finished, so as to determine the defect information;

By adopting the embodiment, the unique marks are marked on the display substrate to enable the placing cavities of the loading container to be in one-to-one correspondence with the unique marks, so that when a certain process is finished, the newly added missing piece position after the process is finished can be known by comparing the unique mark list formed after the previous process is finished.

It will be appreciated, of course, that after each process, if a loading container has a missing patch, the list of unique identifiers needs to be updated based on the missing patch. For example, when a display substrate of a certain placement cavity is cleaned and supplemented with a new display panel, the unique identifier corresponding to the placement cavity needs to be updated. For another example, after the patch is completed, if two placement cavities of a certain layer of the loading container are empty, the unique identifier corresponding to the position in the list needs to be updated to be empty or "0".

As another alternative embodiment, determining whether a patch operation is required for a load container to be loaded may include the steps of:

Acquiring an image of the loading container to be loaded;

identifying the image by utilizing an image identification technology to determine the defect information in the loading container to be loaded; for example, the image is of the side shown in fig. 2A (here, the side of the loading container should be generally transparent so that the image can reflect the placement of the display substrate therein), and when the image is compared with the original image, the position of the defect in the loading container can be determined;

By adopting the embodiment, the position of the missing piece in the loading container can be known through the image recognition technology, so that the implementation is convenient, and manual participation is not needed.

Furthermore, as an alternative embodiment, the step of determining whether the patch operation needs to be performed on the loading container to be loaded may be manually performed, that is, an operator on the production line is used to check each loading container, determine whether the patch is needed according to the check result, and input patch information into the operating system through an operation client (Operator Interface Client, abbreviated as OIC), so that the operating system may determine whether the patch operation needs to be performed on the loading container to be loaded according to the patch information, and issue a corresponding control instruction.

Optionally, step 106: and if the loading container to be loaded does not need to be subjected to patch operation, controlling the production equipment to load the loading container and carrying out double-sheet production on the display substrate placed in the loading container.

In this step, if there is no missing piece in the device container, or although there is missing piece, the missing piece will not affect the double-piece production (for example, two placement cavities on the same layer are all empty), then the patch operation may not be performed, so as to control the production device to load the loading container and perform double-piece production on the display substrate placed therein, as shown in fig. 2B.

Step 108: if the loading container to be loaded needs to be subjected to patch operation, determining the piece missing information of the loading container, and controlling the production equipment to carry out patch operation on the loading container according to a preset patch rule and the piece missing information.

In this step, if there is a missing piece condition in the loading container to be loaded, which affects normal double-piece production, a patch is required, and the patch can be completed according to a preset patch rule.

As an optional embodiment, determining whether the patch operation needs to be performed on the loading container to be loaded according to the defect information in the loading container to be loaded includes:

if a single-chip state exists in the loading container to be loaded, performing patch operation on the loading container to be loaded according to the preset patch rule;

optionally, if the monolithic state does not exist in the loading container to be loaded, no patch operation is required for the loading container to be loaded.

In this embodiment, the monolithic state refers to that only one of two placement cavities of the same layer places a display substrate to be processed (refer to a layer where a missing piece exists in the left half portion of fig. 2C to 2J), and the production apparatus can only perform double-piece production, and the double-piece production can only take out two display substrates from the same layer placement cavity to perform double-piece production, if the layer placement cavity is in the monolithic state, only one display substrate can be taken out, which will cause malfunction of double-piece production, and therefore, patch operation needs to be performed on the loading container having the monolithic state.

Optionally, the preset patch rules include at least one of a same-container patch, a different-container patch, and a empty-load container patch;

It will be appreciated that the patch operations of the present disclosure are primarily patch operations performed on a single sheet state to compensate for the single sheet state to ensure double sheet production, and thus, specific patch modes may be selected as desired, without specific limitation.

As an optional implementation manner, the preset patch rule includes:

Rule one: if there are at least two of the monolithic states in the same load container to be loaded, then a same container patch (onecstostarting) is performed.

Onecstostarting: the display substrate is positionally adjusted in a single loading Container (CST), as shown in fig. 2C and 2D, with the left half being the loading container before the patch and the right half being the loading container after the patch.

Rule II: if there is a single-chip state in the loading container to be loaded after the in-container patch is completed, a out-container patch (twosttsorting) is performed.

Twocststarting: the position of the display substrates is adjusted to each other between the two loading Containers (CST), and fig. 2E and 2F show schematic diagrams of the display substrates of the right loading container being fed into the left loading container.

It should be noted that when there are more than two loading containers in a single-chip state, the loading containers may be grouped into two groups (they may be sequentially grouped after being ordered according to the number of the loading containers), and then the loading containers in the same group perform the patch so that the patch operation is regular and can not occur in the case of a patch error or a cyclic patch.

Rule III: if the single-chip state exists in the loading container to be loaded after the steps are finished, the idle loading container patch is carried out, namely the display substrate to be processed is extracted from the idle loading container and is placed in the defect position of the loading container to be loaded. The idle loading container is a loading container special for completing patch, wherein the display substrate is only used for meeting the patch of the loading container, so that the loading container has no single-chip state, further, the double-chip production can be normally carried out, and after the display substrate in the idle loading container is fed into the normal loading container, the product formed after the process of finishing is not qualified. Fig. 2G to 2J are schematic views showing the extraction of the display substrate from the empty loading container on the right side and the replenishment of the loading container on the left side.

After the preset patch rule is adopted, patches can be completed for all loading containers with single-chip states, so that double-chip production can be normally performed.

In some cases, the two parallel columns of placing containers of the loading container are a first column of placing containers and a second column of placing containers, respectively, and the display substrates placed in the two columns of placing containers respectively cannot be confused with each other, so as an alternative embodiment, the preset patch rule further includes:

if the placing cavity in the first row of placing containers needs a patch, only the display substrate to be processed can be extracted from the first row of placing containers of the loading container to complete the patch;

if the placement cavities in the second column of placement containers require a patch, then only the display substrate to be processed can be extracted from the second column of placement containers of the loading container to complete the patch.

As shown in fig. 2I, after the same-container patch and the different-container patch, there may still be more than one single-chip state in the second column placement container of one or some loading containers, where the display substrate cannot be extracted from the first column to perform the patch for the second column under the condition of strictly distinguishing the first column from the second column, and therefore, only the display substrate belonging to the second column can be extracted from the empty loading container to perform the patch.

Alternatively, the display substrate may be placed in the empty loading container only in the first column or the second column, so that the empty loading container may be selected in a targeted manner without confusion during the patch. Optionally, the production equipment corresponding to each process is provided with a corresponding idle loading container, and when the idle loading container provided by the production equipment is consumed, the idle loading containers provided by the production equipment of other processes can be also called.

Step 110: after the patch is completed, the production equipment is controlled to load the loading container and perform double-sheet production on the display substrate placed therein, as shown with reference to fig. 2B.

As can be seen from the foregoing embodiments, in the control method for producing double sheets of a display panel provided by the embodiments of the present disclosure, by determining whether a loading container to be loaded needs to be subjected to patch operation, if not, performing double sheet production, if so, performing patch operation according to a preset patch rule, and performing double sheet production after patch is completed, thereby ensuring that the loading container can adapt to double sheet production, and further ensuring that double sheet production can be performed normally.

In one or more embodiments of the present disclosure, controlling the production apparatus to load the loading container and perform a double-sheet production on a display substrate placed therein includes: controlling the production equipment to load the loading container and carrying out double-sheet production on the display substrate placed in the loading container by using double mechanical arms;

In this embodiment, the single-sheet production corresponds to the double-sheet production, that is, the production apparatus performs production of only one display substrate, instead of simultaneously performing production of two display substrates.

By adopting the embodiment, when one of the double mechanical arms has a fault, the production equipment is controlled to be switched from double-piece production to single-piece production, so that the production mode of the production equipment is changed in time when the production equipment does not have double-piece production conditions, and the normal operation of a production line is further ensured. Optionally, the display panel double-sheet production control method further includes:

and if the product inlet of the production equipment is occupied, controlling one mechanical arm of the double mechanical arms to grasp the occupied object, and controlling the other mechanical arm of the double mechanical arms to place the display substrate to be processed.

By adopting the embodiment, when the product inlet of the production equipment is occupied, the occupied objects can be cleaned by the double mechanical arms, the product can be placed at the same time, the smooth production process is ensured, and the production efficiency is improved.

The embodiment of the disclosure also provides an embodiment of the display panel double-sheet production system, which can solve the problem of system failure in a single-sheet state to a certain extent. Fig. 3 is a schematic diagram illustrating a structure of an embodiment of a display panel double-sheet production system according to an embodiment of the present disclosure.

As shown in fig. 3, the display panel double-sheet production system includes:

at least one loading container 20 configured to: placing a display substrate 30 to be processed; alternatively, the display substrate may be an organic electroluminescent (Organic Electroluminesence Display, abbreviated as OLED) display panel, or a liquid crystal display panel (Liquid Crystal Display, abbreviated as LCD), which is not limited herein;

at least one production device 40 configured to: sending a double-sheet production request; receiving a double-sheet production control instruction and carrying out double-sheet production; and receiving a patch operation instruction and performing patch operation;

a control system 50 configured to:

receiving a double-sheet production request sent by the production equipment 40;

determining whether a patch operation is required for the loading container 20 to be loaded according to the double-sheet production request;

alternatively, if the loading container 20 to be loaded is not required to be subjected to the patch operation, controlling the production equipment 40 to load the loading container 20 and perform the double-sheet production on the display substrate 30 placed therein;

If the loading container 20 to be loaded needs to be subjected to patch operation, determining the piece missing information of the loading container 20, and controlling the production equipment 40 to carry out patch operation on the loading container 20 according to a preset patch rule and the piece missing information;

after the patch is completed, the production apparatus 40 is controlled to load the loading container 20 and perform a double-sheet production on the display substrate 30 placed therein.

From the above embodiments, it can be seen that, in the display panel double-sheet production system provided by the embodiment of the present disclosure, by determining whether a loading container to be loaded needs to be subjected to patch operation, if not, double-sheet production is performed, if so, patch operation is performed according to a preset patch rule, and after patch is completed, double-sheet production is performed, so that the loading container is ensured to be suitable for double-sheet production, and further normal double-sheet production is ensured.

In general, in a front end of line (FAB) for manufacturing display panels, there may be a plurality of manufacturing facilities corresponding to a plurality of manufacturing processes, and at the same time, in mass-producing display panels, one manufacturing LOT (LOT) may have a plurality of display substrates to be processed, so that a plurality of loading containers 20 may be required to place the display substrates to be processed, and the manufacturing facilities sequentially load the loading containers 20 and perform the production under the corresponding processes when performing the production.

The display panel production equipment firstly has the function of a double-sheet operation mode, namely the capability of processing two display panels at one time, but the double-sheet operation is not defined in the interface of the existing manufacturing execution system (Manufacturing Execution System, abbreviated as MES) and the equipment automatic system (Equipment Auto System, abbreviated as EAS), and meanwhile, the message (message) reported by the production equipment cannot be processed by the MES, so that the MES cannot meet the online double-sheet operation mode.

To solve this problem, as one embodiment of the present disclosure, the control system includes:

a device automation system (EAS) configured to: respectively carrying out data interaction with the production equipment and the manufacturing execution system; the control instruction generated by the manufacturing execution system is converted into an instruction which can be identified by the production equipment and is sent to the production equipment;

a Manufacturing Execution System (MES) configured to: generating a corresponding control instruction according to the information reported by the equipment automatic system;

and the equipment automatic system and the manufacturing execution system adopt a preset message format to realize communication through message middleware. For example, the message middleware may be implemented using TIBCO message middleware from TIBCO software corporation.

By adopting the embodiment, the message format which is well agreed by the two parties is created through the butt joint of the MES and the EAS, and the message middleware is utilized to realize communication so as to realize double-sheet operation, and the double-sheet operation mode can effectively improve the production efficiency and is helpful for large orders and orders with short delivery cycle. The adoption of the message middleware can effectively ensure the communication stability of the systems of the two parties, and can not cause production accidents due to communication problems.

As an alternative embodiment, the step of determining whether the patch operation needs to be performed on the loading container to be loaded may be performed manually, that is, an operator on the production line is used to check each loading container, determine whether the patch is needed according to the check result, and input patch information into the operating system through an operation client (OIC), so that the operating system may determine whether the patch operation needs to be performed on the loading container to be loaded according to the patch information, and issue a corresponding control instruction.

In the display panel production process, the FAB section production mode is to load two display substrates in one loading container, and the number of the display substrates in one loading container is twice as many as the number of the display substrates in one loading container. However, sometimes the loading containers cannot be filled, for example, one loading container normally has 20 layers and 40 display substrates (one layer for two) can be loaded, but due to an abnormal situation (the display panel is scrapped in the production process or the like), some layers in one loading container are loaded with only one display substrate or no display substrate (empty layer), that is, 40 sheets are not loaded, and an empty position occurs. If a single-chip state exists in some layers of the loading container and the loading container cannot be automatically patched due to the occurrence of the vacant positions, the utilization rate of the loading container is reduced, the overall production rhythm is low, and the equipment and the system cannot automatically patch.

To solve this problem, in the present embodiment, the patch is performed by manually controlling the production apparatus, for example, as shown in fig. 4, a flowchart is implemented for the overall system. The display panel double-piece production system comprises EAS, MES, OIC. The user sends patch reservation information to the MES by operating a client (OIC), which is processed by the first server or first server cluster CNXsvr of the MES and stored in the database DB. After loading the loading container CST, the production standby end sends a Message (Message) of a double-piece production request (lotinfodownloadreqest) to the EAS, the Message is sent to a second server or a second server cluster PEXsvr of the MES after being analyzed by the EAS, the second server or the second server cluster PEXsvr of the MES processes according to the Message, whether patch reservation information of the loading container exists is searched from a database, data is integrated according to a query result, the Message is assembled into a Message according to a preset communication protocol, then the Message is sent to the EAS, and the Message is converted into a Message which can be identified by production equipment after being analyzed by the EAS and sent to the production equipment. After the patch is completed, the user also needs to perform a supplementary account operation (patch information input) on the MES through the OIC, so that the entity and the information are ensured to be consistent. In addition, if no suitable display substrate is to be patched, the process may continue under conditions of dissatisfaction.

As an alternative embodiment, in the Message agreed with both the MES and EAS, the MES creates the Message for a two-piece operation. When the production equipment is in a normal double-piece production mode, the Message content does not need to contain information such as the direction of a display substrate; when the production equipment is in the patch mode, the patch mode needs to be manually switched on the equipment by a production equipment engineer, and the Message contains information such as the destination of the display substrate. Under normal conditions, the display substrate in the loading container is full, no patch is needed, and only information interaction is needed normally according to interfaces defined by the EAS and the MES; in the patch mode, the reserved information (such as the position where the display substrate will arrive, the identification of the loading container and the product inlet (port) information of the equipment) needs to be fetched so as to ensure that the display substrate is accurately fed into the target position, so that the EAS can analyze according to the Message and send the information of accurately fetching the display substrate to the production equipment for patch, and double-patch operation is ensured.

Optionally, the MES and the EAS docking Message are in xml format, and the Message body contains main information such as the destination of the display substrate, so that the production equipment can accurately take and produce the Message after identifying the Message.

Optionally, the MES system needs to develop a reservation function capable of performing a two-sheet operation, including at least one of a same-container patch, a different-container patch, and a empty-loading-container patch, in order to implement a patch when a loading container needs a patch, and specify a target position to which a display substrate needs to be moved by the function. The same-container patch refers to the position movement of the display substrate in one CST, the different-container patch refers to the designated layer of the CST of which two display substrates in different CSTs are moved from one to the other, and the empty loading container patch refers to the extraction of the display substrate from the empty loading container and placement in the missing piece position of the loading container, thereby ensuring the target CST double-piece operation. If the reservation is not needed, the MES transmits information to the EAS according to a normal double-sheet mode, and the EAS analyzes and transmits the information to production equipment for production after receiving the information.

Optionally, the database DB creates a reserved table for reserved data storage, including a reserved table and a reserved history table, and after reservation, the reserved data is stored, the current reserved state is recorded, and when the equipment is finished, the field information is changed to be finished, and reserved processing can be performed again.

According to the embodiment, the detailed analysis is carried out according to the double-piece operation mode of the equipment, the data are extracted, the system modeling is carried out, the deep mining is carried out on the original MES system, the MES system meeting the double-piece operation is developed, the difficult problem of the online double-piece operation is solved, and the problems of productivity and production efficiency in the production process are solved by matching with the process equipment.

As an alternative embodiment, as shown in fig. 2A, the loading container 20 includes two rows of placing containers 21/22 arranged in parallel, the placing containers 21/22 include a plurality of placing cavities 211/221 arranged in a stacked manner, and the placing cavities 211/221 are used for placing the display panel 30 to be processed.

As an alternative embodiment, the control system 50 is configured to: in an initial state, giving unique identification to each display substrate to be processed; recording the placement positions and the unique identifiers of the display panels to be processed placed in the loading container in an initial state, and packaging the placement positions and the unique identifiers of the display substrates to be processed into initial loading information;

It will be appreciated, of course, that after each process, if a loading container has a missing patch, the list of unique identifiers needs to be updated based on the missing patch. For example, when a display substrate of a certain placement cavity is cleaned and supplemented with a new display substrate, the unique identifier corresponding to the placement cavity needs to be updated. For another example, after the patch is completed, if two placement cavities of a certain layer of the loading container are empty, the unique identifier corresponding to the position in the list needs to be updated to be empty or "0".

As another alternative embodiment, the production device 40 is configured to: loading an image acquisition device, and acquiring an image of the loading container to be loaded by using the image acquisition device; wherein the image displays a missing piece position in the loading container to be loaded;

The control system 50 is configured to:

acquiring an image of the loading container to be loaded;

By adopting the embodiment, the defect information in the loading container can be obtained through the image recognition technology, so that the implementation is convenient, and manual participation is not needed.

As an alternative embodiment, the control system is configured to:

Optionally, the preset patch rule includes:

As an alternative embodiment, the preset patch rule includes:

rule one: if there are at least two of the monolithic states in the same load container to be loaded, then performing a co-container patch (onecstostarting);

rule II: if the single-chip state exists in the loading container to be loaded after the same-container patch is finished, performing different-container patch;

rule III: and if the single-chip state exists in the loading container to be loaded after the steps are finished, extracting the display substrate to be processed from the idle loading container and placing the display substrate in the chip-missing position of the loading container to be loaded.

As shown in fig. 2F, after the same-container patch and the different-container patch are passed, there may still be more than one single-chip state in the second column placement container of one or some loading containers, at this time, in the case of strictly distinguishing the first column from the second column, the display panel cannot be extracted from the first column for the second column to perform the patch, and therefore, only the display substrate belonging to the second column can be extracted from the empty loading container to perform the patch.

In one or more embodiments of the present disclosure, the production facility 40 is configured to: and loading double mechanical arms and carrying out double-sheet production by utilizing the double mechanical arms.

According to the embodiment, the MES is in butt joint with the EAS interface and is provided with the double mechanical arms, meanwhile, support of loading container (2 panels are assembled on one layer) hardware is achieved, and the online double-Panel production operation can be achieved, so that the production rhythm is quickened. The working principle of the double mechanical arms is that for an online device, the actions of taking a piece from a CST and throwing the piece into the device can be realized at the same time by the double mechanical arms. The manipulator arm with the double-piece operation mode can take two pieces of Panel at one time, so that production materials can be effectively utilized, and the production efficiency can be improved.

Optionally, the control system 50 is configured to:

By adopting the embodiment, when one of the double mechanical arms has a fault, the production equipment is controlled to be switched from double-piece production to single-piece production, so that the production mode of the production equipment is changed in time when the production equipment does not have double-piece production conditions, and the normal operation of a production line is further ensured.

Optionally, the control system 50 is configured to:

In the processing process of the equipment, if a Robot (Robot) is single mechanical arm equipment, only 1 display substrate of a layer of Cassette can be taken at a time, when the port of the equipment is in and out of the same port, the Robot can take out the display substrate of the port preferentially and put the display substrate into a CST, and then the display substrate is taken out of the CST and put into the equipment, so that the overall processing period of the LOT is long, and the production efficiency is lower. Therefore, for the case that the port of the production equipment is shared by in/out, if the double mechanical arms are to throw in the display panel to the production equipment, the process that the display substrate happens to be on the equipment port is finished, the port is occupied, so that the robot cannot continue to throw in sheets, at the moment, one mechanical arm can take down the display substrate from the port of the equipment, and the other mechanical arm grabs the display substrate to be processed and places the display substrate on the port of the equipment, so that the taking-out and throwing-in actions are completed, and the working efficiency of the equipment is increased.

Optionally, the dual robot arm requires two modes to effectively implement a dual slice operation.

Mode 1: in a normal production mode, two display substrates can be taken out of the CST according to one-time Robot of double-sheet operation, and the substrates are put into equipment at one time for technological production, so that the production efficiency can be effectively improved.

Mode 2: when a single-chip condition occurs in CST (only one display substrate is on one layer of CST), a patch needs to be performed, and the patch mode may be that patch (twocststarting) is performed from other CST, or patch (onecststarting) may be adjusted from self.

The control instruction of the patch is issued by the MES, the instruction is transmitted to the EAS, the EAS analyzes the instruction, and the analyzed instruction is forwarded to the production equipment, so that the production equipment performs patch operation according to the instruction.

Alternatively, when the production equipment is in the normal production mode, the patch can not be automatically performed, and when the production equipment is in the idle state (the equipment is in the idle state and no production is performed), the patch mode (onecssort or twostcssort) is automatically switched to after the specified time of the site is exceeded.

After switching to the patch mode, the production equipment reports a load request (CST) to the MES, the MES analyzes according to the reported command to obtain the working mode of the current equipment, judges whether the current equipment is in the patch mode, and if the current equipment is in the patch mode, searches the CST with a single chip in storage (stock) equipment and conveys the CST to the production equipment for patch operation.

After the CST without a single chip is carried to the production equipment, the production equipment sends a loading completion message (loadComplete) and a production information downloading message (lotInfoDown loadRequest) to the MES, the MES obtains the message and analyzes the message to obtain the placing cavity map information (slotMap) of the CST in the message, wherein the information refers to which layer of placing cavity in the CST has a display substrate and which layer of placing cavity does not have a display substrate, and meanwhile, the information is also compared with the information of the display substrate stored in the MES.

And developing a judging algorithm in the MES, checking the position information of the display substrate in the CST to judge by adopting a circulating traversal mode, judging whether the CST can carry out self patch adjustment (oneCT Sorting), and if so, adopting an oneCT Sorting mode to carry out patch. In the process of patching, the MES is automatically matched according to slotMap information of the CST, single piece information is supplemented to a piece missing target position, then the information is stored in an MES DB, meanwhile, message of the patch is assembled and contains the forward information (target CST, target position and target Port information) of a display substrate, after Message assembly is completed, the MES sends the Message to production equipment, and the equipment performs patching operation according to the Message information, so that the patching operation flow is completed.

When the judgment algorithm is researched and developed in MES, the position information of the display substrate in CST is checked to judge in a cyclic traversal mode, and when the patch is judged to be needed from other CSTs, a twoCSTS calling mode is adopted. At this time, according to information (LOT information) of the target CST, the product spec finds a LOT which can be paired for mass production, and carries out patch operation on production equipment, after the original CST is carried on the production equipment, a loading completion Message (loadComplete) and a production information download Message (lotInfoDown LoadRequest) are reported to the MES, then the MES stores information of a display panel which can be patched to the target CST according to the display panel information in the CST, meanwhile, assembles a Message of the patch, sends the Message to a loading container for preparation, completes patch operation, and if the CST which can be patched cannot be found, adopts a CST which is in a type of searching for idle (dummy) for patch.

After the patch is finished, the production equipment reports an unloading message (unloadRequest) to the MES, the MES replies to the production equipment after receiving the message, and the CST automatically conveys the message to the stock equipment to prepare for production.

Optionally, after loading on the port of the device, the CST entity sends a Message to the MES through the TIBCO Message middleware, the MES parses the Message after receiving the Message, and issues a Message according to the current state of the device (the Message is defined by the systems of the two parties before), and the EAS parses the Message after receiving the Message, and sends the film taking action to the device for processing. The double mechanical arm equipment of the production equipment performs sequential sheet taking action, and then the display panel is put into the production equipment or subjected to patch operation.
