Description

Technical Field

[0001] This specification relates to the field of logistics management, and more specifically, the present application relates to a logistics management method and related equipment. Background Art

[0002] In an actual production workshop, there are multiple process equipment, which are arranged in sequence in the production workshop according to the sequence of the process flow. The raw materials are placed in the transfer unit for transfer between different process equipment. Each transfer unit can be used to place one or more raw materials to be processed. Each process equipment may include one or more feeding ports. The feeding port is used to place the transfer unit so that the robot in the process equipment can grab the raw materials in the transfer unit and bring them to the process equipment for process processing. After the corresponding process processing, the process equipment can be exited and the transfer unit can be transported between different process equipment by a transfer vehicle.

[0003] At present, due to the limited number and transportation capacity of transfer vehicles, in order to avoid the situation where the transfer units in the feeding port can be withdrawn but there is no idle feeding port in the process equipment of the next process, causing the transfer units to pile up on the transfer vehicle, thereby affecting the transfer efficiency of the transfer vehicle, in actual production workshops, each process equipment is usually equipped with its corresponding storage area, which is used to store transfer units to alleviate the feeding pressure of the feeding port and the transportation pressure of the transfer vehicle. However, in the case of full production or overproduction, the storage pressure of the storage area increases sharply, the storage space of the storage area is limited, and the transportation capacity of the transfer vehicle is insufficient, which may cause the transfer units waiting to exit the process equipment to be unable to be transferred to the process equipment corresponding to the next process in time, affecting the production rhythm.

[0065] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0066] In an actual production workshop, there are multiple process equipment, which are arranged in sequence in the production workshop according to the sequence of the process flow. The raw materials are placed in the transfer unit for transfer between different process equipment. Each transfer unit can be used to place one or more raw materials to be processed. Each process equipment may include one or more feeding ports, which are used to place the transfer unit so that the robot in the process equipment can grab the raw materials in the transfer unit and bring them to the process equipment for process processing.

[0067] After the raw materials in the target transfer unit arrive at the target feeding port of the first process equipment, the raw materials in the target transfer unit can be grabbed by the robot arm of the first process equipment and put into the first process equipment for process treatment. After the raw materials are processed, the robot arm grabs the raw materials that have undergone the first process treatment and puts them into the initial position of the raw materials in the target transfer unit. After all the raw materials in the target transfer unit have undergone process treatment, the target transfer unit can exit the target feeding port, so as to make way for the next transfer unit that will enter the target feeding port, and transfer the target transfer unit to the second process equipment for the second process treatment through the transfer vehicle.

[0068] In some cases, due to the presence of multiple process equipment in a production workshop, transfer vehicles are required to transport transfer units between different process equipment, but the number and capacity of transfer vehicles are limited. In order to avoid the situation where the transfer unit in the feeding port can be withdrawn but there is no idle feeding port in the process equipment of the next process, causing the transfer unit to pile up on the transfer vehicle, thereby affecting the transfer efficiency of the transfer vehicle, in actual production workshops, each process equipment is usually equipped with its corresponding storage area, which is used to store transfer units to relieve the feeding pressure of the feeding port and the transportation pressure of the transfer vehicle.

[0069] However, in the case of full production or overproduction, the storage pressure in the storage area increases sharply, the storage space in the storage area is limited, and the transportation capacity of the transfer vehicle is insufficient, which may cause the transfer unit waiting to exit the process equipment to have nowhere to exit or to be unable to exit in time. Since all processes of the process equipment in the entire production workshop are continuous, the target transfer unit cannot exit in time, which may cause the current process equipment to be idle, or the process equipment of the next process to be idle. It should be noted that the above-mentioned production workshop can be a workshop for producing display screens, the process equipment can be process equipment for producing display screens, the feed port can be a port of the process equipment, the raw material can be Glass for screen production, the transfer unit can be a CST (cassette) used to transfer Glass, and the storage area can be a STK (stocker) used to store CST.

[0070] In order to ensure the continuity of the process and avoid idleness of process equipment, this application proposes a logistics management method, please refer to Figure 1 , is a flow chart of a logistics management method provided in an embodiment of the present application, which may specifically include:

[0071] S110, when the target transfer unit in the first process equipment can exit the target feeding port, obtaining the first process continuous remaining time of the first process equipment;

[0072] Exemplarily, after all raw materials of the target transfer unit in the first process equipment have been processed by the first process, and the manipulator has placed all processed raw materials into the corresponding storage space of the target transfer unit, the target transfer unit can exit the target feeding port. It is understandable that when the target transfer unit can exit, it can send an exit request to the management system or display the status that it can exit the process equipment through an indicator light or a screen.

[0073] In the case that the target transfer unit can exit the target feeding port, the first process continuous remaining time of the first process equipment is obtained. The first process continuous remaining time refers to the time that the first raw material to be processed by the first process corresponding to the first process equipment can maintain the continuous operation of the first process equipment when the target transfer unit does not exit. The first process continuous remaining time is the longest time that the target transfer unit can wait at the target feeding port to ensure that the first process equipment will not be idle. It should be noted that the first raw material is the raw material that has not been processed by the first process.

[0074] S120, obtaining the remaining continuous time of the second process of the second process equipment, wherein the second process equipment is the process equipment corresponding to the next process after the target transfer unit exits the target feeding port;

[0075] Exemplarily, the second process equipment is the equipment corresponding to the next process that needs to be executed after the target transfer unit exits the target feeding port, and the second process continuous remaining time refers to the time during which the second raw material to be processed by the second process corresponding to the second process equipment can ensure the continuous operation of the second process equipment when the target transfer unit does not exit (i.e., it cannot move to the second process equipment). The second process continuous remaining time is the longest time that the target transfer unit can wait at the target feeding port to ensure that the second process equipment will not be idle. It should be noted that the second raw material is the raw material that has been processed by the first process but not the second process.

[0076] S130, determining the shorter of the first process continuous remaining time and the second process continuous remaining time as the maximum exit waiting time of the target transfer unit;

[0077] Exemplarily, step S110 and step S120 can be used to obtain the first process continuous remaining time and the second process continuous remaining time. The first process continuous remaining time is the maximum time for ensuring that the target transfer unit corresponding to the first process equipment will not exit the first process equipment when Idle occurs. The second process continuous remaining time is the maximum time for ensuring that the target transfer unit determined by the second process equipment will not exit the first process equipment when Idle occurs. In order to ensure the process continuity of the first equipment and the second equipment at the same time, the shorter of the first process continuous time and the second process continuous time is used as the maximum time for the target transfer unit not to exit the target feeding port in the first equipment (i.e., the maximum exit waiting time).

[0078] S140. Control the target transfer unit to exit the target feeding port according to the maximum exit waiting time.

[0079] Exemplarily, based on the maximum exit waiting time obtained in step S130, if the maximum exit waiting time is less than or equal to 0, it means that an idle situation has occurred in the first process equipment and / or the second process equipment. In order to ensure the process continuity of the first process equipment and / or the second process, the target transfer unit needs to be immediately withdrawn from the above-mentioned target feeding port. If the maximum exit waiting time is greater than 0, the target transfer unit can be withdrawn from the target feeding port before the maximum exit waiting time is reached, so that when the transport capacity of the transfer vehicle used to move the transfer unit is tight, buffer time can be provided for the transfer vehicle, and the target transfer unit can be temporarily stored through the target feeding port to reduce the storage pressure of the storage area.

[0080] In summary, the method provided in the embodiment of the present application, when the target transfer unit in the first process equipment can exit the target feeding port, determines the maximum exit waiting time of the target transfer unit in the first process equipment by obtaining the continuous remaining time of the first process and the continuous remaining time of the second process, and determines when the target transfer unit will exit the target feeding port based on the maximum exit waiting time. The logistics management method provided by this scheme can ensure the process continuity of the first process equipment and the second process equipment. When the maximum exit waiting time is greater than 0, the target transfer unit does not need to exit immediately, and only needs to exit the target feeding port before the maximum exit waiting time is reached, thereby reducing the transportation pressure of the transfer vehicle, and through this method, the target feeding port can temporarily store the target transfer unit, thereby reducing the storage pressure of the storage area. This method can not only effectively avoid the idleness of process equipment, but also provide a more intelligent logistics management solution for full-load or overload production to avoid logistics bottlenecks.

[0081] In some examples, the method further includes:

[0082] When the target transfer unit exits the target feeding port, obtaining the feeding port status of the second process equipment;

[0083] In the case where there is an idle feeding port in the second process equipment, the target transfer unit is directly transferred to the idle feeding port.

[0084] Exemplarily, when the target transfer unit exits the target feeding port, the feeding port status of the second process equipment is obtained, and the feeding port status may include being fully occupied or partially idle. If there is an idle feeding port in the second process equipment, the target transfer unit is directly transferred to the idle feeding port of the second process equipment for the second process equipment to perform the second process treatment.

[0085] like Figure 2As shown, a possible target transfer unit transfer method is used. When the target transfer unit (transfer unit 1A) exits the target feeding port (feeding port 11), the feeding port status of the feeding port 21, the feeding port 22 and the feeding port 23 of the second process equipment are obtained, and the feeding port 23 is obtained to be in an idle state. At this time, the target transfer unit is placed on the transfer vehicle, and the target transfer unit is moved to the corresponding position of the idle feeding port 23 of the second process equipment by the transfer vehicle, and the transfer unit 1A is directly inserted into the feeding port 23.

[0086] In summary, the method provided in this embodiment, when the target transfer unit exits the target feeding port, obtains whether there is an idle feeding port in the second process equipment. If there is an idle feeding port, the target transfer unit is directly moved to the idle feeding port. Compared with the method in the prior art that the exiting target transfer unit must be placed in the storage area, this saves the moving path of the target transfer unit and improves the transfer efficiency.

[0087] In some examples, the method further includes:

[0088] When all the feeding ports of the second process equipment are occupied, obtaining the storage status of the second storage area corresponding to the second process equipment;

[0089] In the case that there is remaining accommodation space in the second storage area, the target transfer unit is transferred to the remaining accommodation space.

[0090] Exemplarily, when the target transfer unit exits the target feeding port, the feeding port status of the second process equipment is obtained. If all feeding ports in the second process equipment are occupied, the storage status of the second storage area corresponding to the second process equipment is obtained. If there is remaining storage space in the second storage area, the target transfer unit is transferred to the remaining storage space in the second storage area for storage.

[0091] like Figure 3 As shown, another possible method of transferring the target transfer unit is that when the target transfer unit (transfer unit 1A) exits the target feeding port (feeding port 11), the feeding port status of the feeding port 21, the feeding port 22 and the feeding port 23 of the second process equipment are obtained, and it is obtained that the feeding port 21, the feeding port 22 and the feeding port 23 are all occupied. At this time, the storage status of the second storage area is obtained. If there is remaining accommodation space in the second storage area, the target transfer unit is placed on the transfer vehicle, and the target transfer unit is moved to the second storage area by the transfer vehicle, and the target transfer unit is moved to the remaining accommodation space in the second storage area.

[0092] In summary, the method provided in this embodiment, when the feeding ports of the second process equipment are all occupied, by acquiring the storage status of the second storage area corresponding to the second process equipment, when there is remaining storage space in the second storage area, the target transfer unit is moved to the remaining storage space in the second storage area for storage. This ensures that in the current situation, the target transfer unit is closest to the second process equipment, making it convenient for the second process equipment to grab the second raw material in the target transfer unit.

[0093] In some examples, the method further includes:

[0094] When the second storage area is full, the target transfer unit is transferred to the first storage area corresponding to the first process equipment.

[0095] Exemplarily, when the target transfer unit exits the target feeding port, the feeding port status of the second process equipment is obtained. If all feeding ports in the second process equipment are occupied, the storage status of the second storage area corresponding to the second process equipment is obtained. If the second storage area is also full, the target transfer unit is transferred to the remaining capacity space in the first storage area for storage.

[0096] like Figure 4 As shown, another possible target transfer unit transfer method is that when the target transfer unit (transfer unit 1A) exits the target feeding port (feeding port 11), the feeding port status of the feeding port 21, the feeding port 22 and the feeding port 23 of the second process equipment are obtained, and it is obtained that the feeding port 21, the feeding port 22 and the feeding port 23 are all occupied. At this time, the storage status of the second storage area is obtained, and the second storage area is full. At this time, the target transfer unit is moved to the remaining accommodation space of the first storage area.

[0097] In summary, the method provided in the embodiment of the present application, when the second process equipment has no idle feeding ports and the corresponding second storage areas are full, uses the first storage area to store the exited target transfer units, thereby avoiding affecting the process continuity of the first process equipment. At the same time, the exited target transfer units are stored in the first storage area closest to the second process equipment, which is convenient for later transfer, enriches the logistics management plan, and alleviates the storage pressure in the second storage area.

[0098] In some examples, the method further includes:

[0099] When there are M transfer units in N process equipment that can exit their corresponding process equipment, obtain the maximum exit waiting time of the M transfer units respectively;

[0100] Determine the exit priority of the M transfer units according to the longest waiting time of the M exits;

[0101] The time for the M transfer units to exit their corresponding process equipment is determined based on the exit priority.

[0102] For example, there may be multiple process equipment in a production workshop, and each process equipment may have a transfer unit that exits the process equipment. The existing method is to exit the transfer unit in the order of issuing exit requests. However, in the case of insufficient transport capacity of the transfer vehicle, some target transfer units requested to exit may not be able to exit their corresponding process equipment in time, which may affect the process continuity of the current process equipment and its corresponding process equipment for the next process, and then cause the current process equipment and the process equipment for the next process to be idle.

[0103] To avoid this phenomenon, the method provided in the embodiment of the present application is as follows: Figure 5 As shown, in the case where there are M transfer units that can exit among N process equipment, some process equipment and corresponding transfer units are not shown. Based on the method described in the above embodiment, the maximum exit waiting time corresponding to each transfer unit to be exited from the process equipment is obtained respectively, and the priority of its exit is determined from high to low according to the maximum exit waiting time from small to large, so as to determine the exit order of the M transfer units according to the priority level and the transportation capacity level of the transfer vehicle in the whole production line, thereby ensuring that the transfer unit with the shortest longest waiting time in the whole production line is exited first, thereby ensuring the process continuity of all process equipment in the whole production line.

[0104] In summary, the method provided in the embodiment of the present application obtains the longest waiting time of the M transfer units respectively when there are M transfer units that can exit their corresponding process equipment among N process equipment, and determines the priority according to the longest waiting time, and determines the exit time of the transfer unit to be exited in the entire production line based on the above priority, thereby ensuring that all equipment in the entire production line will not be idle, making the exit sequence more reasonable and the logistics management method more intelligent.

[0105] In some examples, obtaining the continuous remaining time of the first process of the first process equipment includes:

[0106] The continuous remaining time of the first process is determined according to the input time of the first raw material to be input into the first process equipment and the first transfer time of the transfer unit to enter the target feeding port.

[0107] For example, to ensure the process continuity of the first process equipment, the transfer unit that arrives at the target feed port needs to be in place before all the un-added first raw materials in the feed port are added, so as to ensure that the first raw materials can be continuously added to the first process equipment.

[0108] like Figure 6As shown, the input time of the first raw material into the first process equipment in the transfer unit 1B and the transfer unit 1C corresponding to the first process equipment is obtained, and the first transfer time of the transfer unit D moving to the target feeding port is obtained. The first raw material input time is subtracted from the first transfer time, and the continuous remaining time of the first process can be determined.

[0109] In some examples, the method further includes:

[0110] Obtaining the amount of the first raw material that has not been fed into all the feeding ports of the first process equipment and the first feeding rhythm;

[0111] The input time of the raw materials to be input into the first process equipment is calculated according to the quantity of the first raw material and the first feeding rhythm.

[0112] For example, the input time of the raw material of the first process equipment can be determined according to the product of the number of the first raw materials not input in all the feeding ports to be input into the first equipment and the first feeding rhythm. It can be understood that each equipment has its corresponding process, and each equipment has a corresponding feeding rhythm according to its corresponding process, and the feeding rhythm can be determined according to historical feeding data.

[0113] In some examples, the method further includes:

[0114] Determine a first theoretical transfer time according to the positional relationship between the transfer unit to be introduced into the target feeding port and the first process equipment and historical transfer data;

[0115] Determine the first transfer coefficient based on the busyness of logistics;

[0116] The first transfer time is determined according to the first theoretical transfer time and the first transfer coefficient.

[0117] Exemplarily, by obtaining the position of the transfer unit to be entered into the target feeding port, the positional relationship between the transfer unit to be entered into the target feeding port and the first process equipment can be obtained. It should be noted that the position of the transfer unit to be entered into the target feeding port may be on the way of transfer, or it may be in the storage area corresponding to the previous process. Since the storage area is a three-dimensional storage area, when considering the positional relationship, it is necessary to consider not only the horizontal positional relationship between the two, but also the spatial positional relationship between the two. The theoretical time for the transfer unit to arrive at the first equipment can be determined based on historical transfer data. However, since the transportation capacity in the production line is always changing, the first transfer coefficient is determined based on the busyness of the logistics corresponding to the first process equipment and the transfer unit. The first transfer duration can be obtained by multiplying the first transfer coefficient by the first theoretical transfer duration. It can be understood that in the case of relatively busy logistics, a coefficient larger than 1 can be set for adjustment, such as 1.5.

[0118] Furthermore, the continuous remaining time of the first process can be determined by formula (1):

[0119] WT1=TT1*RG1-b1*TRT1 (1)

[0120] In formula (1), WT1 is the remaining continuous time of the first process, TT1 is the first feeding cycle, RG1 is the amount of the first raw material, b1 is the first transfer coefficient, and TRT1 is the first theoretical transfer time.

[0121] In some examples, obtaining the second process continuous remaining time of the second process equipment includes:

[0122] The second process continuous remaining time of the second process equipment is determined according to the input time of the second raw material to be input into the second process equipment and the second transfer time of the target transfer unit to transfer to the second process equipment.

[0123] For example, to ensure the process continuity of the second process equipment, it is necessary to move the target unit to the feeding port of the second equipment before all the un-input second raw materials are put in, so as to ensure that the second raw materials can be put into the second process equipment uninterruptedly. Therefore, to ensure the process continuity of the second process equipment, the difference between the input time of the second raw material of the second process equipment and the second transfer time of the target transfer unit to the above-mentioned second process equipment is determined as the second process continuity remaining time of the second process equipment.

[0124] In some examples, the method further includes:

[0125] Obtain the amount of remaining raw materials that have not been fed into the second process equipment in all feeding ports of the second process equipment, the amount of transferred raw materials in the transfer unit on the way to the second process equipment, and the second feeding rhythm of the second process equipment;

[0126] The input time of the raw materials to be input into the second process equipment is calculated according to the quantity of the second raw material and the second feeding rhythm, wherein the quantity of the second raw material is the sum of the quantity of the remaining raw materials and the quantity of the transferred raw materials.

[0127] Exemplarily, the input time of the raw materials of the second process equipment can be determined according to the product of the quantity of the first raw materials and the second feeding rhythm, and the quantity of the second raw materials is the sum of the quantity of the remaining raw materials not input in all the feeding ports of the second process equipment and the quantity of the transferred raw materials in the transfer unit on the way to the second process equipment. It can be understood that each equipment has its corresponding process, and each equipment has a corresponding feeding rhythm according to its corresponding process, and the feeding rhythm can be determined according to the historical feeding data.

[0128] like Figure 6 As shown, the amount of remaining raw materials not fed into all the feeding ports of the second process equipment includes the amount of raw materials in the transfer units 2A, 2B and 2C that have not been fed into the second process equipment, and also includes the amount of raw materials in the transfer unit (transfer unit E) on the way to the above-mentioned second process equipment.

[0129] In some examples, the method further includes:

[0130] Determine a second theoretical transfer time according to the positional relationship between the target transfer unit and the second process equipment and the historical transfer data;

[0131] Determine the second transfer coefficient based on the busyness of logistics;

[0132] The second transport time is determined according to the second theoretical transport time and the second transport coefficient.

[0133] For example, by obtaining the position of the target transfer unit and the second process equipment, the positional relationship between the target transfer unit and the second process equipment can be obtained, and the theoretical time for the target transfer unit to arrive at the second equipment can be determined based on the historical transfer data. However, since the transportation capacity in the production line is always changing, the second transfer coefficient is determined based on the busyness of the logistics between the second process equipment and the first process equipment, and the second transfer duration can be obtained by multiplying the second transfer coefficient by the second theoretical transfer duration. It is understandable that in the case of relatively busy logistics, a coefficient greater than 1 can be set for adjustment, such as 1.5.

[0134] Furthermore, the second process continuous remaining time can be determined by formula (2):

[0135] WT2=TT2*(RG2+WG)-b2*TRT2 (2)

[0136] In formula (2), WT2 is the remaining continuous time of the second process, TT2 is the second feeding cycle, RG2 is the amount of remaining raw materials not fed into all feeding ports of the second process equipment, WG is the amount of transferred raw materials in the transfer unit during the transfer of the second process equipment, (RG2+WG) is the amount of the second raw material, b2 is the second transfer coefficient, and TRT2 is the second theoretical transfer time.

[0137] Furthermore, after a preset time, WT1 and WT2 need to be recalculated, so as to ensure that the maximum waiting time for exiting each process equipment to be exited is updated in time when there is a change in information, adjust the exit and transfer plan, ensure the process continuity of each process equipment, and avoid Idle. It should be noted that the information change can be the location of the target transfer unit or the location of other transfer units, or the quantity of the first raw material or the quantity of the second raw material, etc., wherein the preset time can be 2 minutes, and the specific value is not limited.

[0138] In some examples, the method further includes:

[0139] The feeding rhythm of each process equipment is determined based on the historical production data of the corresponding process of each process equipment.

[0140] Exemplarily, since each process equipment can perform different processes according to different setting parameters, different processes correspond to different feeding rhythms. Specifically, the intercepted samples can be grouped for each process equipment, different products, and different processes based on the daily production data as samples, and the average value in each group is calculated. The minimum average time of sampling a specific process under the corresponding product for the corresponding process equipment is selected as the feeding rhythm of the process equipment. The data is collected every day, and if the current feeding rhythm is less than the feeding rhythm of the previous day, the current feeding rhythm is determined as the feeding rhythm of the process equipment.

[0141] In summary, the method provided in the embodiments of the present application can ensure that each process equipment has sufficient supply of raw materials at the fastest production rhythm by continuously collecting the shortest feeding cycle of different process equipment for different products in different processes every day, thereby ensuring that each process equipment avoids idleness.

[0142] In one possible implementation, the above-mentioned logistics management method can be used in a screen production workshop to perform a card return operation on a CST loaded with Glass. The correspondence between the following embodiments and the above-mentioned management method is as follows: the feed port is a port, the raw material is Glass used for screen production, the transfer unit is a CST (a cassette for loading glass) used to transfer Glass, the storage area is used to store STK of CST, the source device is a first process device, and the destination device is a second process device.

[0143] like Figure 7As shown, it is a schematic diagram of the structure of an intelligent card return logistics management system, wherein 701 is a MES (Manufacturing Execution System) database cluster, 702 is a MDW (Management data warehouse) database cluster, 703 is a real-time command dispatch system with built-in intelligent prediction module and command dispatch module, 704 is a material control system cluster, and 705 is an AMHS (Automatic Material Handing System) lower handling system.

[0144] The specific execution steps of the CST handling process can be:

[0145] Step 71: Set up a scheduled job in the DB to collect data ( Figure 7 Data collection DB cluster).

[0146] Data collection includes T / T collection (i.e. feeding rhythm), and data collection also includes average handling time collection.

[0147] In some examples, the specific method of T / T collection is as follows: Figure 8 As described above, since the amount of Glass process history data is large and difficult to process, the data warehouse (MDW DB) synchronizes the Glass process history records in the production database (MES DB), and the latest T / T is obtained after data truncation, cleaning, grouping, iterative calculation, and comparison with historical data, and then synchronized to the production database through OGG (Oracle Golden Gate, a log-based structured data replication software) technology. The T / T collection method may specifically include S210 to S290:

[0148] S210, obtaining Glass process history data, that is, Glass generation process data.

[0149] S220, Sample collection: According to the Glass process history records, obtain the T / T of all Glass of the equipment on the day and arrange them in chronological order.

[0150] S230. Cut samples by product model and process. When the product or process changes, cut process samples.

[0151] S240, filtering available data in the truncated sample, that is, filtering samples whose length is greater than a preset length.

[0152] S250, numbering and grouping samples within the cutoff: number each Glass sample T / T within the cutoff in the order of 1, 2, 3, ..., and group them.

[0153] S260. Calculate the minimum average value: calculate the average value for each group and take the minimum average value: Min(Avg(1~N),Avg(2~N+1),Avg(3~N+2),……).

[0154] S270, output standard T / T: When different process equipment calculated on the day performs different processes in the production of different products, the minimum average value of each process is compared with the historical minimum average value. If the minimum average value of the day is less than the historical minimum average value, the minimum average value of the process performed by the process product produced by the process equipment is updated to the minimum average value of the day, otherwise it is not updated.

[0155] S280, data synchronization: synchronize the data warehouse settlement results to the production database through OGG.

[0156] S290, generate the data format after standard T / T processing.

[0157] In some examples, the average handling time is determined as follows: Fig. 9 As shown, the production library sets a timed job, obtains the transportation time between different STKs on the same floor, the transportation time within the same STK, the transportation time of different STKs on different floors, etc., obtains the corresponding transportation time for each transportation situation, and records and updates it to the database, which may include:

[0158] S310, obtaining CST handling history data;

[0159] S320, sample collection: obtain data of all CSTs that have been transported within 12 hours based on the CST transport history data;

[0160] S330, sample grouping: because it involves same-floor transportation and cross-floor transportation, for example: transportation within the same STK on the 2nd floor, transportation across STKs on the 2nd floor, transportation within the same STK on the 4th floor, transportation across STKs on the 4th floor, transportation from the 2nd floor to the 4th floor, and transportation from the 4th floor to the 2nd floor;

[0161] S340, sample truncation: The data in each group is taken from the first 1000 instructions to ensure the timeliness and fault tolerance of data transfer.

[0162] S350, average transport time calculation: calculate the average transport time of all transport instructions in the sample and update it into the database.

[0163] S360. Construct a data format of average transport time.

[0164] Step 72: DSP AP ( Figure 7The intelligent prediction module and command dispatching cluster) divide the equipment transportation priority according to the model. The CST with the higher priority will be returned and transported first.

[0165] The minimum waiting time for the card to be returned (i.e. the maximum waiting time for the card to be returned) can be calculated by using equations (1) and (2), which can be obtained by Figure 7 The intelligent prediction module shown in the figure is implemented as follows: Fig.10 As shown:

[0166] S401: Request the number of Glasses that are not being processed on all the feeding ports of the card return device;

[0167] S402: predict the next CST according to the appointment information, the position of each CST in WIP (Work In Progress), the priority of Lot (the general term for all glasses in CST, each CST corresponds to a Lot), Cycle Time, etc., and output the CST position;

[0168] S403: Determine whether the next CST of the source device is found;

[0169] S404: If the next CST of the source device is not found, the waiting time of the source device is set to 100, which can be > 0 in principle;

[0170] S405: Determine which type of average transport time to use based on the positional relationship between the CST and the equipment, in order to calculate a more accurate waiting time;

[0171] S406: Calculate the minimum waiting time of the source device according to formula (1), that is, the first process continuous remaining time WT1;

[0172] S407: Find the downstream device of the CST according to the reservation information;

[0173] S408: Determine whether there is a reserved destination device;

[0174] S409: If the destination device is not found, the waiting time of the destination device is set to 100, which can be > 0 in principle;

[0175] S410: The number of Glasses that are not being processed at all current feeding ports of the destination equipment;

[0176] S411: The number of Glass being transported at the feeding port of the destination equipment;

[0177] S412: determining which type of average transport time to use based on the positional relationship between the CST and the destination device in order to calculate a more accurate waiting time;

[0178] S413: Calculate the minimum waiting time of the destination device according to formula (2), that is, the second process continuous remaining time WT2;

[0179] S414: Take the minimum value from WT1 and WT2 as the maximum time that the CST to be returned can stay at the port, that is, by selecting the minimum value from WT1 and WT2, it is possible to determine the maximum time that the CST to be returned can be temporarily stored at the port without affecting the process continuity of the source device and the destination device.

[0180] Step 73: Before the DSP AP (Dispatch Application) dispatches a command to the device with the highest priority, it needs to perform a more reasonable command dispatch based on the current STK storage situation and the priority of the source device and the destination device. This is completed by the command control module. The specific control process is as follows: Fig.11 As shown:

[0181] S510, the source device requests a card return and sends a card return signal;

[0182] S520, judging whether the states of the device and the STK connected to the device meet the transport conditions;

[0183] S530, obtaining the minimum waiting time outputted in the intelligent prediction module;

[0184] S540, determine whether the minimum waiting time is greater than 0, if so, execute step S590, if not, execute S550;

[0185] S550, determine whether the STK connected to the destination device is full, if yes, execute S570; if not, execute S560;

[0186] S560, transport the CST to the STK connected to the destination equipment so that the CST can be transported to the equipment in time after the feeding port of the destination equipment becomes empty;

[0187] S570, determine whether the minimum waiting time of the source device is > 0, if yes, execute S590, if no, execute S580;

[0188] S580, transporting the CST to the STK connected to the source device, thereby shortening the total transport path;

[0189] S590 and CST are temporarily stored at the feeding port of the equipment to relieve the storage pressure of STK and shorten the transportation path

[0190] Step 74: After the command is issued, the MCS (Material Control System Application) splits the Macro Command into Micro Commands and sends them to the AMHS for the transport action execution, such as Figure 7 The commands in the application cluster are executed.

[0191] Through the above-mentioned intelligent card return logistics management model, the model calculation speed and accuracy are improved through the data acquisition module. Through the intelligent prediction module, the problem of disordered handling priority is solved, and the instructions being executed are screened out as the instructions with the highest priority. Through the command dispatch control module, the output value of the intelligent prediction module is combined with the current STK storage situation to make the dispatched commands more intelligent, which not only relieves the storage pressure of STK but also ensures that the process equipment will not be idle due to slow transportation to the greatest extent. Thereby improving the automation level of logistics in the FPD (flat panel display) industry.
