[0042] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0044] The embodiment of the present invention provides a work order management method, referring to Figure 1 , Figure 1 The figure is a flowchart of a first embodiment of a work order management method of the present invention.

[0045] In this embodiment, the work order management method includes the following steps:

[0046] 1. Work order generation: Work orders can be generated by the ERP / MES system. Cycle plans are made based on sales orders, planned orders, experimental orders or rework orders, and information such as product models and customers needs to be associated. When generating a work order, it is necessary to fill in the planned production date, planned completion date, planned production quantity and planned completion quantity to provide data basis for subsequent statistics on the completion of the work order.

[0047] If the work order is generated by the ERP system, the MES and ERP systems need to be interfaced to achieve data transmission and unification.

[0048] 2. Work order BOM: BOM (bill of materials) is the bill of materials, and work order BOM is the bill of materials associated with the work order. BOM is formulated by the process department according to the product model. BOM needs to include main materials and auxiliary materials, and auxiliary materials need to define unit consumption. Each work order needs to be associated with BOM according to the work order type and product model.

[0049] After the work order is associated with the BOM, the material collection plan can be issued to the WMS system. The planned collection quantity of the main material for each shift of this work order can be calculated based on the planned production quantity / [(planned completion date-planned production date)*shift]. The auxiliary materials can be calculated based on the planned collection quantity of the main material*unit consumption.

[0050] 3. Material collection: Production staff apply for materials according to the production plan of each work order per day and each shift. After the materials are collected, the WMS and MES systems need to transfer data. At this time, the materials need to be issued with associated work orders, that is, when the materials arrive at the production workshop, the associated work orders can be queried according to the material code. After obtaining the material collection information, MES needs to split the work order according to the batch information of the main material, and split the work order into sub-work orders. The workshop uses the sub-work orders for production. The work orders used in subsequent production are the sub-work orders split by MES.

[0051] 4. Work order production: Since materials are associated with work orders, the work order can be obtained according to the material code when the material is put on the machine in the material delivery room. MES obtains the work order according to the material code on the equipment, and then associates the material box ID of the unloaded material with the material batch and the work order, so that the raw materials and work orders can be traced through the material box ID.

[0052] During the texturing process, the cells in the material box will be imported into the basket. At this time, EAP will import the cells in the material box into the basket and upload the ID to MES. MES will generate a virtual ID for a single cell based on the work order and batch associated with the material box ID. From then on, the work order will be put into production and the association between the single semi-finished product and the work order will be realized.

[0053] 5. Production of work orders associated with battery cells: Battery cells are loaded into baskets for flow traceability between processes. From the time the texturing process is started, the work order associated with each battery cell can be obtained based on the basket. Therefore, when the basket is loaded from the boron expansion to the sorting process, MES will associate the work order of the battery cell in the basket with the equipment, and then know the work order produced by the current equipment.

[0054] 6. Reworked cell-related work orders: During the production process, the cell cannot be produced any more due to process abnormalities, equipment jams, etc., and needs to be reworked and cleaned. The cell produced in this situation is called a reworked cell. Since the frequency of reworked cells is not high, they need to accumulate to a certain number before they can be cleaned. Therefore, reworked cells cannot be re-produced according to the original work order. The input quantity and output quantity of the work order must be dynamically conserved, so the number of reworks generated needs to be recorded. When rework occurs, the MES system will obtain the current production work order based on the equipment and provide personnel with rework reports.

[0055] 7. Work order completion: The battery cells are considered completed after they are output from the sorting equipment and become finished products. At this time, the MES system will calculate the number of completed work orders based on the output battery cells, but because the fragments generated during the production process cannot be fully counted, the system cannot automatically complete the work order. Therefore, the completion of the work order requires human intervention. When the personnel complete the work order, the system will calculate the number of fragments generated by this work order according to the fragment calculation formula. The calculation formula is: number of fragments = input quantity - output quantity - rework quantity.

[0056] The work order management method for solar cell manufacturing proposed in this embodiment is based on the traditional solar cell manufacturing model, which does not completely break the existing production management method, but also realizes digital production management. The planned order is strongly associated with the production plan, which provides important data for the cost accounting of solar cell enterprises, reduces the manual data entry operation of personnel, and more completely and accurately manages the quantity changes of the entire life cycle from raw materials to finished products.

[0057] Further references Figure 2 , Figure 2 This is a flow chart of a second embodiment of a work order management method of the present invention.

[0058] In this embodiment, the work order management method includes the following steps:

[0059] Step S10: Generate a work order for the solar cell.

[0060] In this embodiment, the executor of this embodiment is a work order management device, wherein the work order management device has functions such as data processing, data communication and program running. The work order management device can be a computer terminal device or other network device, and of course it can also be other devices with similar functions, and this embodiment does not limit this.

[0061] It should be noted that traditional solar cell manufacturing uses silicon wafer batches to manage production work orders. Batches are generated by raw material manufacturers. Based on batch management, semi-finished products and finished products can be traced back to raw materials. However, this method has a low traceability rate, requires production personnel to monitor the line, and cannot be associated with production orders.

[0062] In order to solve the above technical problems, in this embodiment, a work order for solar cells is generated; the work order is associated with a bill of materials according to the product model corresponding to the work order, and a material collection plan is issued; in response to the material collection request of the production personnel, and after obtaining the material collection information, the work order is split into multiple sub-work orders based on the batch information of the main material of the material collection plan; each sub-work order is put into production respectively, and the corresponding sub-work order is determined to be completed after the battery cell is output from the sorting equipment; after all sub-work orders are completed, the work order is determined to be completed, and the status information of the solar cell is adjusted from the production status to the completion status. Specifically, it can be implemented as follows.

[0063] In the specific implementation, in this embodiment, it is necessary to first generate a work order for the production process of solar cells. There are two ways to generate a work order. One of the ways is to generate it by the Enterprise Resource Planning (ERP) system. If the work order is generated by the ERP system, the Manufacturing Execution System (MES) system needs to be interfaced with the ERP system to achieve data transmission and unification. If it is generated by the MES system, the subsequent work order management process can be carried out directly.

[0064] It should be noted that the work order can be planned by the ERP / MES system according to the sales order, planned order, experimental order or rework order, and needs to be associated with product model, customer and other information. When the work order is generated, it is necessary to fill in the planned production date, planned completion date, planned production quantity and planned completion quantity to provide data basis for the subsequent statistics of the work order completion status.

[0065] Step S20: Associating the work order with the bill of materials according to the product model corresponding to the work order, and issuing a material requisition plan.

[0066] The bill of materials is also called the work order BOM (bill of materials). The BOM is prepared by the process department based on the product model. The BOM needs to include the main materials and auxiliary materials, and the auxiliary materials need to define the unit consumption. Each work order needs to be associated with the BOM based on the work order type and product model.

[0067] After the association is completed, the material collection plan can be issued to the Warehouse Management System (WMS).

[0068] It should be noted that the material requisition plan in this embodiment includes the planned requisition quantity of the main material and the planned requisition quantity of the auxiliary materials, wherein the planned requisition quantity of the main material can be determined by the planned production quantity, the planned completion date, the planned production date and the shift, such as the planned production quantity / [(planned completion date-planned production date)*shift], and the planned requisition quantity of the auxiliary material can be determined by the planned requisition quantity of the main material and the unit product consumption, such as the planned requisition quantity of the main material*unit consumption.

[0069] Step S30: responding to the material requisition request of the production staff and splitting the work order into a plurality of sub-work orders based on the batch information of the main material of the material requisition plan after obtaining the material requisition information.

[0070] Production staff apply for materials according to the production plan of each shift per day. Specifically, the ERP system formulates a material requisition form for each shift based on the work order plan, and sends the material requisition form to the WMS system. Staff go to the warehouse to pick up materials according to the material requisition form. After receiving the material requisition request, they respond to the material requisition request and, after obtaining the material requisition information, split the work order into sub-work orders through the MES system according to the batch information of the main material. The workshop uses the sub-work orders for production, and the work orders used in subsequent production are the sub-work orders split by MES.

[0071] Step S40: Each sub-work order is put into production respectively, and the corresponding sub-work order is determined to be completed after the battery cell is output from the sorting equipment.

[0072] For any sub-work order, the production process in this embodiment is specifically as follows: after detecting that the production personnel have picked up the materials to the factory delivery room, the materials are loaded onto the silicon wafers in the factory delivery room, and unloaded from the machine after the material box is full of silicon wafers; the material in the material box is transported to the texturing equipment for loading, and the silicon wafers are transferred from the material box to the flower basket through the texturing equipment; after completing the flower basket guiding, the work order is put into production through the MES system according to the work order bound to the material box identification code, and a virtual battery cell identification code, i.e., the wafer identification code, is generated. In order to achieve data traceability, in this embodiment, the MES system determines the corresponding sub-work order based on the material code of the material loaded onto the machine, and binds the material code, the corresponding sub-work order and the material delivery equipment; after the material box is full of silicon wafers and unloaded from the machine, the enterprise application platform (Enterprise Application Platform, EAP) system reports the material box identification code that has been unloaded, and the MES system obtains the corresponding sub-work order and material batch according to the equipment that has been unloaded, and binds the material box identification with the sub-work order and the material batch.

[0073] This embodiment further illustrates that, for example, since materials are associated with work orders, work orders can be obtained according to the material code when loading in the material delivery room. MES obtains the work order according to the material code on the equipment, and then associates the material box id with the material batch and work order, so that the raw materials and work orders can be traced through the material box id. When the material is loaded for velveting, the battery cells in the material box will be imported into the flower basket. At this time, EAP will import the battery cells in the material box into the flower basket id and upload it to MES. MES generates a virtual id for a single battery cell according to the work order and batch associated with the material box id. From then on, the work order is put into production, and the association between the single semi-finished product and the work order is realized.

[0074] After the production is completed, the battery cells between the processes are loaded into the basket for flow traceability. Starting from the texturing process, the work order associated with each battery cell in the basket can be obtained according to the basket. Therefore, when the basket is loaded from the boron expansion to the sorting process, the MES will associate the work order of the battery cell in the basket with the equipment, and then know the work order produced by the current equipment.

[0075] During the production process, battery cells may not be able to continue production due to process abnormalities, equipment jams, etc., and need to be reworked and cleaned. The battery cells generated in this situation are called reworked cells. When the presence of reworked cells is detected, the rework quantity corresponding to the reworked cells is recorded in this embodiment, and when reworked, the sub-work order currently in production is obtained through the MES system for production personnel to fill in the rework report. Since the frequency of reworked cells is not high, they need to accumulate to a certain number before they can be arranged for cleaning, so reworked cells cannot be re-produced according to the original work order. The input quantity and output quantity of the work order must achieve dynamic conservation, so the number of reworks generated needs to be recorded.

[0076] Step S50: After all sub-work orders are completed, the work order is determined to be completed, and the status information of the solar cell is adjusted from the production status to the completion status.

[0077] In this embodiment, the relationship between the work order and the sub-work order can be referred to Figure 3 As shown, after all sub-work orders are completed, the entire work order is considered completed, and the battery cell changes from being put into production to being completed. After reaching the planned completion quantity, the personnel perform the work order closing operation.

[0078] It should be noted that the battery cells are considered finished after they are produced from the sorting equipment. At this time, the battery cells become finished products. At this time, the MES system will calculate the number of completed work orders based on the produced battery cells. However, since the fragments generated during the production process cannot be fully counted, the system cannot automatically complete the work order. Therefore, the completion of the work order requires human intervention. After the personnel complete the work order, the system will calculate the number of fragments generated by this work order according to the fragment calculation formula. The calculation formula is: number of fragments = input quantity - output quantity - rework quantity.

[0079] This embodiment generates a work order for solar cells; associates the work order with the bill of materials according to the product model corresponding to the work order, and issues a material collection plan; responds to the material collection request of the production personnel, splits the work order into multiple sub-work orders based on the batch information of the main material in the material collection plan; puts each sub-work order into production, and determines that the corresponding sub-work order is completed after the battery cell is output from the sorting equipment; after all sub-work orders are completed, the work order is determined to be completed, and the status information of the solar cell is adjusted from the production status to the completion status, and the work order management function is added without changing the traditional solar energy production and manufacturing mode, so as to manage the entire life cycle of the battery cell from the texturing to the sorting process, so that its semi-finished products, fragments, reworked pieces, and finished products have orders to rely on and data to trace.

[0080] In addition, an embodiment of the present invention further provides a storage medium, on which a work order management program is stored. When the work order management program is executed by a processor, the steps of the work order management method described above are implemented.
