Description

Technical Field

[0001] The present invention relates to the field of automated production technology, and in particular to a hybrid line scheduling method, device, electronic equipment and storage medium. Background Art

[0002] For the construction of automated production lines in enterprise workshops, the actual conditions are sometimes complicated:

[0003] (1) In order to balance the production process rhythm of the product, multiple devices are required to produce in parallel in some processes;

[0004] (2) Considering the utilization rate of production resources, some processes require the combination of multiple devices to complete a process, and for the consideration of transmission efficiency, the combined workstations need to use transition direct connection lines for transmission when transferring between combined workstations;

[0005] (3) The available space of the production line is limited. The production line uses a straight line layout with equipment on both sides. However, most standard equipment enters the station from one side, resulting in different physical locations of the main line entrances of the same process equipment on both sides of the production line. One side of the equipment needs to pass through the previous main line again after the product is produced.

[0006] In these cases, the flow scheduling logic for online automatic production of products is more complicated:

[0007] First of all, it is necessary to identify the parallel stations and combined stations in the process route according to different products. The equipment specified for different product processes is different.

[0008] Secondly, it is necessary to solve the preferential allocation of parallel workstations and the control of the last equipment entrance product; the control of the processing sequence of combined workstation equipment and the selection of flow routes between combined workstations; and the logical control of the release of repeated main line nodes through which the outbound products of mirrored equipment flow.

[0009] Finally, the information about the actual equipment used by the product in the parallel workstation and combined workstation, as well as data such as the time of entering and exiting the equipment, are recorded as input data for scheduling implementation and information component of product traceability.

[0010] With the development of new products, improvement of production processes and introduction of new types of equipment, this type of high-mix line often appears in the transformation of existing automated production lines.

[0046] Embodiment 1

[0047] Please refer to Figure 1 This embodiment provides a mixed line scheduling method, which is particularly suitable for high-mixed line scheduling. The method includes the following steps:

[0048] S01. Configure process equipment; among them, three types of equipment stations need to be defined: single station, combined station and parallel station, and a parallel station can include a combined station; specifically: according to the analysis of the actual situation of the mixed line, there are multiple types of equipment stations on the line, and the types of equipment stations are single station and parallel station; the parallel station preferably includes a combined station; among them, the single station is set as: one process corresponds to only one equipment, and the product in one process can only enter the corresponding one equipment for online production; the parallel station is set as: one process is completed by multiple equipments separately, and the product can select any one equipment for online production; the combined station is set as: one process needs to use multiple equipments to produce in sequence;

[0049] S1. Control the flow of products and / or carriers through the entry and exit nodes, obtain product information and query the corresponding process of the product; wherein the entry and exit nodes are set on the line body, and the products flow on the line body with the carrier as the carrier;

[0050] S2. If the equipment corresponding to the entry and exit nodes is a single-station equipment and belongs to the next process, the product is controlled to enter the station for production;

[0051] S3. If the equipment corresponding to the entry / exit node is the equipment included in the parallel workstation, first check whether the equipment meets the process sequence of the current product. If so, continue to check the availability of the equipment. If the equipment is idle, control the product to enter the station for production. If the equipment is busy, check the availability of other equipment included in the parallel workstation. If there is an idle equipment, the entry / exit node releases the product to flow to the next node.

[0052] S4. If the equipment corresponding to the entry and exit nodes is the equipment included in the parallel workstation, and the parallel workstation includes the combined workstation, first proceed according to step S3 to detect the first station equipment of the combined workstation. If it is, control the product to enter the equipment for production. If there is subsequent equipment, control the product to enter the next equipment for production through the transition line between the combined equipment. When the tail station equipment in the combined equipment processes the product, schedule the product to enter the main line and flow to the next process in the process path.

[0053] In an embodiment of step S01, the patch process requires a dispensing device and a patch machine to be completed together, which is a combined workstation. In order to balance the production rhythm, two patch machines are arranged in the patch process. When the product is produced online, one patch machine can be selected for production at will, which is a parallel workstation. The PCB patch process is a parallel workstation, one way is an automatic patch machine with dispensing + patch integration, and the other way is a separate dispensing machine plus a separate patch machine, and the other way is a combined workstation.

[0054] In one embodiment, in step S1, when the carrier flows through the entry and exit nodes of the line body, the carrier barcode is scanned and the information is read, and the process path information of the product and / or the carrier is queried and used as input data for the scheduling logic; wherein the entry and exit nodes are set as barcode reader detection nodes, and the carrier barcode of the carrier is bound to the product barcode of the product.

[0055] In one embodiment, in step S2, if the equipment corresponding to the entry and exit nodes does not belong to the next process of the product, an alarm message is sent.

[0056] In one embodiment, in step S3, if all the devices included in the parallel workstation are busy, the cache data of each device on the line with cache space is read, and the product is released to the device with less cached products.

[0057] For parallel workstations and combined workstations, it is necessary to define the order of the equipment contained in the automated line layout (first station and last station). Because the line is a linear layout, the product cannot flow back on the production line. When performing automated scheduling, the scheduling method must clarify whether the physical location is the first station or the last station. For combined workstations, you cannot enter the station from an entrance other than the first station. When the production is completed at the last station, the production of this process is considered completed; for parallel workstations, at the entrance of the last station, you need to wait even if the equipment is busy, while the first station can be released in a straight line to the subsequent available equipment. Specifically, in one embodiment of step S3, if the device corresponding to the barcode reader detection node is the last station device, the product is controlled to wait to enter the station; wherein, the last station device belongs to the equipment included in the parallel workstation.

[0058] In the above technical solution, steps S1-S4 reflect the implementation means of the scheduling logic of the hybrid line. To realize the automatic scheduling of product flow during automatic production, it is necessary to automatically identify the product first, and then use logical operations based on its corresponding process and equipment station configuration to feedback to the electrical control system of the automatic production line to complete the product flow control.

[0059] About automatic identification: In order to ensure the compatibility of multiple products in the automated production line, general products are circulated on the line with carriers as carriers. The carrier barcode and product barcode are bound during production preparation, and automatic barcode readers are installed at each entry and exit node on the line. When the carrier passes by, the scanner is triggered to scan the carrier barcode. The scheduling software receives the scan information, reads the current carrier information, and then queries to obtain the set process path information as the input data for the scheduling logic.

[0060] About scheduling strategy:

[0061] When the product / carrier flows through the barcode reader detection node, that is, the entry and exit node, the current product information is obtained and the corresponding process is queried.

[0062] (1) If the equipment corresponding to the node is a single-station equipment and is the next process of the product, the product is scheduled to enter the station for production. If it is not the expected / set / preset next process, an alarm is issued;

[0063] (2) If the node is a device included in a parallel workstation, first check whether it meets the process sequence of the current product, then check the availability of the device. If the device is idle, schedule the product to enter the station for production. If the device is busy, check the availability of other devices included in the parallel workstation. If there is an idle device, release the node and schedule the product to flow to the next node. If all the devices included in the parallel workstation are busy, for the line with cache space, read the cache data of each device and release the product to the device with less cached products. At the same time, if the device corresponding to this node is the last station device among the devices included in the parallel workstation, regardless of other conditions, all products are scheduled to wait for entry into the station for production.

[0064] (3) If the node is a device included in a parallel workstation, and the parallel workstation includes a combination workstation, it is processed according to (2) first. When the first station of the combination workstation is detected, the product is scheduled to enter the equipment for production. After completion, if there is a subsequent equipment, the product is scheduled to enter the next equipment for production through the transition line between the combination equipment. When the equipment marked as the last station in the combination equipment is processed, the product is scheduled to enter the main line and continue to flow to the next process in the process path.

[0065] Among them, for parallel workstations, the completion of any branch indicates the completion of the process. For combined workstations, the middle and tail station equipment must be completed before the process is completed.

[0066] Regarding the flow log: For (high) mixed lines, due to the flexible and complex process configurations, in order to restore the online production status of the product through data records after the product is offline, in addition to recording the product flow operations in units of processes, the corresponding equipment used in the actual production process must also be recorded for parallel workstations and combined workstations, in order to facilitate data analysis of the equipment operation status and quality status.

[0067] In summary, the hybrid line scheduling method of the present invention realizes efficient and flexible scheduling of (high) hybrid lines, combines and reuses single-function equipment through combined workstations, optimizes the equipment resource allocation of the enterprise, and balances the production rhythm of different products through parallel workstations; it meets the production compatibility of multiple products and multiple processes, and greatly improves the operation efficiency of the automatic production line.

[0068] Embodiment 2

[0069] Please refer to Figure 2-Figure 4 This embodiment provides a hybrid line scheduling method. The following technical solution is explained through specific cases for easy reading and understanding.

[0070] like Figure 2 The following is an example of the layout of a (high) mixed line. The yellow and purple parts are parallel workstations and combined workstations, and the other parts are ordinary single-station equipment. The following is a business analysis.

[0071] In the patch process, according to different product processes, the production flow can be divided into the following categories from a business perspective:

[0072] (1) Single-station process production mode

[0073] The order is: dispensing machine, placement machine 2, placement machine 1;

[0074] (2) Parallel workstation production mode

[0075] Glue dispensing machine and SMT station (including SMT 1 and SMT 2). After the product is glued, it will be automatically allocated to one of the SMT 1 and SMT 2 stations for production according to the optimal solution based on the status of SMT 1 and SMT 2.

[0076] (3) Parallel processing station production model

[0077] From the product process point of view, it only includes one SMT process, which corresponds to a SMT parallel workstation. One branch is SMT machine 2 (SMT machine 2 has dispensing and SMT functions), and the other branch includes a combination station of a dispensing machine and SMT machine 1. SMT machine 1 is the tail station of the combination station; SMT machine 2 is the tail station of the parallel workstation.

[0078] Regarding the patch process, Figure 3 As shown, based on steps S1-S4 of the hybrid line scheduling method of the first embodiment and / or the scheduling strategy of the hybrid line scheduling method of the first embodiment, the expected result is that for the (high) hybrid line dispensing and patching part, the processes that can be executed are as follows:

[0079] (1) Glue dispensing → Patch 2 → Patch 1

[0080] The scheduling execution process path is: point A enters the dispensing machine → point B exits the station and enters the main line → point D goes straight → point E enters the placement machine 2 → point F exits the station and enters the main line → point D enters the placement machine 1 → point C exits the station and enters the main line;

[0081] (2) Dispensing → Mounting process in parallel (including Mounting Machine 1 and Mounting Machine 2)

[0082] The scheduling execution path is: point A enters the dispensing machine → point B exits the station and enters the main line → point D determines the use status of placement machine 1 and placement machine 2;

[0083] If SMT machine 1 is the best choice → enter SMT machine 1 → exit at point C and enter the main line, flowing to G;

[0084] If SMT machine 1 is not the best choice → go straight to point D → enter SMT machine 2 at point E → exit at point F and enter the main line, flowing to G;

[0085] (3) Parallel patch workstations (one branch is patch machine 2, the other branch is a combination station of dispensing machine + patch machine 1)

[0086] The scheduling execution path is: Point A determines the equipment usage of two parallel workstations;

[0087] If the dispensing machine is the best choice, then enter the dispensing machine → exit at point B and directly enter the placement machine 1 through the transition line → exit at point C and enter the main line, and flow to G;

[0088] If the dispensing machine is not the best choice → go straight to point D → enter the placement machine 2 at point E → exit at point F and enter the main line, flowing to G.

[0089] Regarding the back-end wedge welding process, Figure 4 As shown, the implementation method is basically the same as the patch process. You only need to pay attention to the use of the transition lines of the two bonding machines on the left to improve the product operation efficiency.

[0090] This section can also be configured with multiple process routes as needed, by combining wedge bonders and ball bonders to meet production needs, including a special route configuration:

[0091] This is configured as a bonding process, wedge bonding 1 and ball bonding 1 are a combined workstation, wedge bonding 2 and ball bonding 2 are also a combined workstation, and these two combined workstations are configured as a parallel workstation.

[0092] The scheduling execution process path is:

[0093] (1) At the combined station of wedge welding 1 and ball welding 1: A enters the station → B exits the station → directly enters the ball welding 1 → D exits the station and goes to the main line → flows to I.

[0094] (2) The routes of the combination of wedge welding 2 and ball welding 2 are different according to the different settings of the first and last stations in the combination. Since there is no mandatory order requirement for the production of products between wedge welding 2 and ball welding 2, wedge welding 2 can be set as the first station, or ball welding 2 can be set as the first station. When wedge welding 2 is the first station, the route is: E entry → F exit on the main line → A straight → C straight → G entry → H exit on the main line → C straight → flow to I. When ball welding 2 is the first station, the route is: A straight → E straight → C straight → G entry → H exit → directly enter wedge welding 2 → F exit on the main line → A straight → E straight → C straight → G straight → flow to I.

[0095] In summary, the present invention provides an efficient scheduling method for a linear layout production line that is compatible with parallel workstations and combined workstations, thereby achieving efficient and flexible scheduling of mixed-type lines. It has the ability to combine different equipment for production according to product production processes, and allows equipment to be run in parallel or combined as needed to meet the production needs of a certain process. It can also adapt to the mixed production of multiple products with different processes, effectively improving equipment utilization and saving production time costs.
