Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of production scheduling, and in particular to an insertion order production scheduling method for an automatic flow line. Background Art
[0002] For microwave device assembly automatic production lines, in order to take into account the production characteristics of small batches and multiple varieties, there are often a variety of different production modes. The most common production mode is the continuous production mode, that is, producing one product in a period of time, and then producing the next product, such as Figure 1 shown.
[0003] It should be pointed out that due to the different sizes of microwave devices, in order to ensure that the width of the track is not affected, a carrier of uniform size is used for circulation in production. The schematic diagram of the carrier is shown in the figure. Figure 2 When the vehicle passes through the intersection of the line body and the branch line entrance, a traffic control inspection will be carried out. If the conditions are met, the vehicle will be pushed into the branch line through the lifting and transverse movement mechanism. Figure 3-Figure 4 However, due to the small batch and multi-variety production of microwave devices, and the different production rhythms of different product equipment, the continuous production mode does not maximize the utilization of equipment. At this time, it is possible to consider using a mixed production line mode of multiple products to improve efficiency, such as Figure 5 .pass Figure 5 It can be seen that different equipment can be used for different tasks at this time, some of which are dedicated equipment and some are shared equipment. This can make full use of the production rhythm of different products and achieve maximum utilization of production lines and equipment.
[0004] The most difficult situation is that there is an urgent task that needs to be inserted into the production order. At this time, the priority of this task is higher than other products in the current production line. It is necessary to give priority to the production of this product if possible. The previous method is often to suspend the current production tasks and take all the products in production offline to ensure the priority production of the insertion order. This mode does meet the priority execution of the insertion order, but it affects the production efficiency of other tasks and reduces the utilization rate of equipment. Considering the small batch and multi-variety production mode of microwave devices, forcibly stopping the production of all products is not the most optimized method. At this time, considering the insertion order is also a mixed line production method, but in this mode, the dedicated equipment designated for the insertion order will give priority to the production of the insertion order products until the insertion order task is completed and then released as a shared resource. Summary of the invention
[0005] In order to solve the above technical problems, the present invention proposes a production scheduling method for automatic flow line. Through an efficient scheduling method, while ensuring the priority execution of the production task, the production of other products can still be taken into account.
[0006] To achieve the above object, the present invention provides a method for scheduling production of automatic flow line inserts, comprising:
[0007] Create a work order, set the work order as an insertion work order, set the process flow, bind the equipment, start the insertion work order and automatically execute the control;
[0008] Taking out the cache tool of the device branch body of the insertion order work order and putting it into the carrier, performing logical judgment on the insertion order work order based on the device branch body, and outputting the judgment result;
[0009] Based on the judgment result, it is determined whether the insertion work order can enter the branch line body to complete the insertion.
[0010] Preferably, before creating the work order, the process includes:
[0011] Production staff prepare materials and data for production tasks, input task requirements, and output materials.
[0012] Preferably, binding the device comprises:
[0013] Production personnel bind product, carrier, and work order information, and clamp the carrier to complete the binding.
[0014] Preferably, before starting the insertion order and automatically executing the control, it also includes adding fields in the equipment management module, and simultaneously configuring the dispensing machine, the placement machine, the manual work station, and the wedge welding machine as the insertion order occupied devices for identifying the control program.
[0015] Preferably, in the automatic insertion control process, the carriers that have been allocated as exclusive equipment are manually taken out and temporarily stored on the line side or placed on the main line track. When the insertion station completes the production of the equipment, the exclusive equipment is released.
[0016] Preferably, performing logical judgment on the insertion work order based on the device branch body includes:
[0017] When the carrier arrives at the outlet of the equipment branch line, determine whether the carrier has a flow to enter this process. If not, pass through the station directly. If there is a flow to enter this process, continue to determine whether there is an insertion task. If not, enter the branch line. If there is an insertion task, continue to determine whether the equipment is assigned to the insertion task process. If not, enter the branch line. If so, continue to determine whether the process task set by the equipment is completed. If not, enter the branch line. If completed, pass through the station directly.
[0018] Preferably, in the insertion order mode, except for the curing furnace, all equipment configured for the insertion order task will give priority to executing the insertion order task, and only when the insertion order task that the equipment needs to execute is completed will it continue to return to the mixed line production mode or continuous production mode to continue production.
[0019] Compared with the prior art, the present invention has the following advantages and technical effects:
[0020] The present invention ensures that high-priority tasks can be completed in the fastest way under the multi-product mixed production mode through the bonding connection single-order scheduling mode, while also ensuring the normal production of other products as much as possible, thereby maximizing the utilization rate of the line and equipment.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0032] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0033] The present invention proposes a method for scheduling production of automatic flow line, comprising:
[0034] Create a work order, set the work order as an insertion work order, set the process flow, bind the equipment, start the insertion work order and automatically execute the control;
[0035] Specifically, before creating a work order, include:
[0036] Production staff prepare materials and data for production tasks, input task requirements, and output materials.
[0037] Furthermore, the binding device includes:
[0038] Production personnel bind product, carrier, and work order information, and clamp the carrier to complete the binding.
[0039] Furthermore, before starting the insertion order and automatically executing the control, it also includes adding fields in the equipment management module, and simultaneously configuring the dispensing machine, the placement machine, the manual work station, and the wedge welding machine as the insertion order occupied devices for identifying the control program.
[0040] In the automatic insertion control process, the carriers that have been allocated as exclusive equipment are manually taken out and temporarily stored on the line side or placed on the main line track. When the insertion station completes the production of the equipment, the exclusive equipment will be released.
[0041] Since there may still be carriers in the cache track at the equipment entrance cache (such as placement machines), and the automatic order insertion control process can only ensure that new products cannot flow into the branch track, the products that have already flowed in cannot be automatically shot out. At this time, in order to ensure that the inserted order products have the highest priority in entering the equipment production, it is necessary to manually take out the carriers that have been allocated as exclusive equipment, including dispensing machines, placement machines, manual work stations, and wedge welding machine entrances. They can be temporarily stored on the line (and put back after the order insertion task is completed) or placed on the main line track.
[0042] The simplest way to release the exclusive equipment is to release it after the insertion work order is completed. However, since the entire process of patch bonding is long, it takes 4-5 hours for a product to flow from dispensing to the final post-bonding inspection. Therefore, if the last product is inspected, it means that the patch machine is occupied and remains idle for 4-5 hours. In this case, the OEE of the equipment will be greatly affected. At this time, the correct way is to judge the exclusive as the insertion work station to complete the production of the equipment and then release it.
[0043] A cache tool of the device branch body of the insertion order is taken out and put into the carrier, a logical judgment is performed on the insertion order based on the device branch body, and a judgment result is output;
[0044] Specifically, performing logical judgment on the insertion order based on the equipment branch body includes:
[0045] When the carrier arrives at the outlet of the equipment branch line, it is determined whether the carrier has a process to enter this process. If there is no process to enter this process, the blocking device is lowered to allow the carrier to enter the next workstation. If there is a process to enter this process, it is determined whether there is an insertion task. If there is no insertion task, the lifting device lifts the carrier to enter the branch line. If there is an insertion task, it is determined whether the equipment is assigned to the insertion task process. If not, the lifting device lifts the carrier to enter the branch line. If so, it is determined whether the process task set for the equipment is completed. If not, the lifting device lifts the carrier to enter the branch line. If completed, it passes the station directly.
[0046] Based on the judgment result, determine whether the insertion work order can enter the branch line to complete the insertion.
[0047] In the insertion order mode, except for the curing furnace, all devices configured for the insertion order task will give priority to executing the insertion order task. Only when the insertion order task that the device needs to execute is completed will it return to the mixed line production mode or continuous production mode to continue production.
[0048] Branch body Fig. 9 As shown, the branch line of the main circulation product, the equipment of the production line of this embodiment is connected to the branch line unit and the branch line body, the branch line can avoid the situation where the equipment is connected to the main line and causes blockage) cache tool, and put it into the carrier, the carrier is as shown Figure 2 As shown, it is used to transport products along the line and deliver them to various work stations.
[0049] In order to more clearly express the technical solution of the present invention, the following specific embodiments are provided to introduce the solution:
[0050] A method for scheduling production of automatic flow line inserts, such as Figure 6 and Table 1, including:
[0051] 1. Process setting: Configure the relevant processes such as dispensing and patching in the process flow of the software, and specify the corresponding equipment.
[0052] 2. Work order settings: Set up the work order and set its properties to insert order, so that the system can know that this work order is an insert order.
[0053] 3. Start the insertion order and automatically execute the control: Since the patch bonding production line relies on the branch line to realize the logical control of scheduling to the process equipment for production. Figure 8 .
[0054] Therefore, the tracks of the dispensing machine, placement machine, manual workstation, and wedge welding machine assigned to the insertion task are set to prioritize the insertion task. In this way, when there is a insertion task, these tracks will no longer accept products of ordinary tasks, but only accept products of the insertion task. Only when the insertion task is completed will they continue to accept ordinary tasks.
[0055] It should be noted that for some continuous-pass equipment, such as curing ovens and equipment with short process times, such as plasma cleaning machines, they can continue to perform ordinary tasks while there are insertion tasks, which will not delay the execution of the insertion tasks.
[0056] In this way, the plug-in single device needs to be configured in the device management module to ensure that the program can identify whether a device is a plug-in single device. Add a field in the device management module - "Whether plug-in single device", and then configure the dispensing machine, placement machine, manual workstation, and wedge welding machine to "plug-in single device". In this way, the control program can identify it well during product circulation.
[0057] 4. Manual processing cache: Since there may be carriers in the cache track at the equipment entrance cache (such as placement machines), and the automatic order insertion control process can only ensure that new products cannot flow into the branch track, and the products that have already flowed in cannot be automatically shot out. At this time, in order to ensure that the order-inserted products have the highest priority in entering the equipment production, it is necessary to manually remove the carriers that have been allocated as exclusive equipment, including dispensing machines, placement machines, manual workstations, and wedge welding machines. They can be temporarily stored on the line (put back after the order insertion task is completed) or put on the main track. (At this time, if it is placed on the main track, it can no longer enter the exclusive equipment due to the branch entrance control function).
[0058] 5. Release of exclusive equipment: The simplest way to release exclusive equipment is to release it after the insertion work order is completed. However, since the entire process of patch bonding is long, it takes 4-5 hours for a product to flow from dispensing to the final post-bonding inspection. Therefore, if the last product passes the inspection, it means that the patch machine is monopolized and remains idle for 4-5 hours. In this case, the OEE of the equipment will be greatly affected. At this time, the correct way is to judge the exclusive as the insertion work station to complete the production of the equipment and then release it.
[0059] Table 1
[0060]
[0061] See the logic flow chart of the judgment of inserting orders when entering the branch line. Figure 7 , which is described as follows:
[0062] When the carrier arrives at the outlet of the equipment branch line, determine whether the carrier has a flow to enter this process. If not, pass through the station directly. If there is a flow to enter this process, continue to determine whether there is an insertion task. If not, enter the branch line. If there is an insertion task, continue to determine whether the equipment is assigned to the insertion task process. If not, enter the branch line. If so, continue to determine whether the process task set by the equipment is completed. If not, enter the branch line. If completed, pass through the station directly.
[0063] In the insertion order mode, except for the curing furnace, all devices configured for the insertion order task will give priority to executing the insertion order task. Only when the insertion order task that the device needs to execute is completed will it continue to return to the mixed line production mode or continuous production mode to continue production.
[0064] Inserting orders will not increase the utilization rate of equipment while ensuring that the inserted order tasks are executed with the highest priority. Compared with the mixed production mode, its equipment utilization rate is usually lower than the latter. Its advantage is that it can ensure that the inserted order tasks can be completed with priority.
[0065] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
