[0043] It should be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application.

[0044] The embodiments of the present application provide a work order management method, which will be described with reference to Figure 1 , Figure 1 Fig. 1 is a flowchart of a first embodiment of the work order management method of the present application.

[0045] In the present embodiment, the work order management method comprises the following steps:

[0046] 1. Work order generation: The work order can be generated by an ERP / MES system, and a periodic plan can be made according to a sales order, a plan order, an experimental order or a rework order, and information such as a product model and a customer needs to be associated. When the work order is generated, a planned production date, a planned completion date, a planned production quantity and a planned completion quantity need to be filled in, so as to provide a data basis for subsequent statistics of the work order completion.

[0047] If the work order is generated by the ERP system, the MES and the ERP system need to be interfaced and connected in series, so as to realize data transmission and unification.

[0048] 2. Work order BOM: BOM (bill of materials) is a bill of materials, and the work order BOM is a bill of materials associated with the work order. The BOM is made by a process department according to a product model, and the BOM needs to contain main materials and auxiliary materials, and the auxiliary materials need to be defined as unit consumption. Each work order needs to associate the BOM according to the work order type and the product model.

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

[0050] 3. Material requisition: production personnel apply for materials according to the daily production plan of each shift, and after the material requisition is completed, the WMS and MES systems need to perform data transmission. At this time, the material needs to be associated with the work order and issued, that is, when the material arrives at the production workshop, it can be queried according to the material code to obtain the associated work order. After obtaining the material requisition information, the MES needs to split the work order according to the batch information of the main material, split the work order into a sub-work order, and the workshop uses the sub-work order for production. The work order used in subsequent production is the sub-work order split by the MES.

[0051] 4. Work order production: since the material is associated with the work order, the work order can be obtained according to the material code when the material is fed into the machine in the material feeding room. The 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 the work order, so that the raw material can be traced through the material box id and the work order.

[0052] When the battery piece in the material box is introduced into the flower basket during the texturing feeding, the EAP will introduce the battery piece in the material box into the flower basket id and upload it to the MES. The MES generates a virtual id for the single battery piece according to the work order and batch associated with the material box id, and the work order is put into production from this point, and the association between the single semi-finished product and the work order is realized.

[0053] 5. Battery piece associated work order production: the battery piece is loaded into the flower basket for flow tracing between processes. From the start of the texturing process, the work order associated with each battery piece in the flower basket can be obtained, so when the flower basket is fed into the equipment from the boron expansion to the sorting process, the MES will associate the work order of the battery piece in the flower basket with the equipment, so that the current work order produced by the equipment can be known.

[0054] 6. Work order associated with rework pieces: during production, due to process abnormalities, equipment blockage, etc., the battery piece cannot continue to be produced and needs to be reworked and cleaned. Such battery pieces are called rework pieces. Since rework pieces occur infrequently and need to accumulate to a certain number before cleaning can be arranged, rework pieces cannot be produced according to the original work order, and the input and output quantities of the work order need to be dynamically conserved, so the number of rework pieces generated needs to be recorded. When rework occurs, the MES system will obtain the current production work order according to the equipment, and provide personnel to fill in the rework report.

[0055] 7. Work order completion: the battery piece is considered complete after being output from the sorting equipment and becomes a finished product. At this time, the MES system will calculate the completion quantity of the work order according to the output battery piece, but since the fragments produced during the production process cannot be completely counted, the system cannot automatically complete the work order. Therefore, the work order completion needs the intervention of personnel. After the personnel operate the work order completion, the system will calculate the fragment quantity generated by this work order according to the fragment calculation formula: fragment quantity = input quantity - output quantity - rework quantity.

[0056] The work order management method applied to solar cell production and manufacturing provided in the embodiment is based on the mode of traditional solar cell production and manufacturing, does not completely break the existing production management mode, and realizes digital production management. The plan order and the production plan are strongly associated, important data is provided for cost accounting of a solar cell enterprise, manual data entry operation of personnel is reduced, and the entire life cycle quantity change from raw materials to finished products is more completely and accurately managed.

[0057] Further referring to Figure 2 , Figure 2 The flowchart of a second embodiment of the work order management method of the present application is shown.

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

[0059] Step S10: generating a work order of a solar cell.

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

[0061] It should be noted that the traditional solar cell manufacturing uses a silicon wafer batch to manage production work orders. The batch is generated by a raw material manufacturer, and the traceability of semi-finished products and finished products to raw materials can be completed according to batch management. However, the traceability rate of this method is not high, production personnel need to monitor the line, and it cannot be associated with production orders.

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

[0063] In a specific implementation, a work order needs to be generated for the production process of the solar cell in the embodiment. The generation of the work order has two modes. One mode is generated by an enterprise resource planning (ERP) system. If the work order is generated by the ERP system, a manufacturing execution system (MES) system needs to be interfaced with the ERP system to realize data transmission and unification. If the work order is generated by the MES system, the subsequent work order management process can be directly performed.

[0064] It should be noted that the work order can be formulated by the ERP / MES system according to a sales order, a planned order, an experimental order or a rework order. The product model and customer information need to be associated. The planned production date, the planned completion date, the planned production quantity and the planned completion quantity need to be filled in when the work order is generated, so as to provide data basis for subsequent statistics of the completion of the work order.

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

[0066] The bill of materials is also called a work order BOM (bill of materials). The BOM is formulated by a process department according to a product model. The BOM needs to include main materials and auxiliary materials. The auxiliary materials need to define unit consumption. Each work order needs to associate the BOM according to the work order type and the product model.

[0067] After the association is completed, the material requisition plan can be issued to a warehouse management system (WMS) system.

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

[0069] Step S30: In response to a material requisition request of a production personnel, the work order is split into a plurality of sub-work orders based on batch information of the main materials of the material requisition plan after the material requisition information is acquired.

[0070] The production personnel perform material requisition according to the daily production plan of each shift of the work order. Specifically, the ERP system formulates a material requisition sheet for each shift according to the work order plan, and issues the material requisition sheet to the WMS system. The personnel perform material requisition to the warehouse according to the material requisition sheet. After receiving the material requisition request, the material requisition request is responded to. After obtaining the material requisition information, the MES system splits the work order into sub-work orders according to the batch information of the main material. The work order is split into sub-work orders. The workshop uses the sub-work order for production. The work order used in subsequent production is the sub-work order split by the MES.

[0071] Step S40: Production of each sub-work order is performed respectively, and it is determined that the corresponding sub-work order is completed after the battery piece is output from the sorting equipment.

[0072] The production process in this embodiment for any sub-work order is specifically that after detecting that the production personnel take the material to the factory material distribution room, the material is loaded on the silicon wafer in the factory material distribution room, and the material box is unloaded after the silicon wafer is collected. The material box is transported to the texturing equipment for loading. The silicon wafer is transferred from the material box to the flower basket through the texturing equipment. After the flower basket guide piece is completed, the MES system performs work order production according to the work order bound by the material box identification code, and generates a virtual battery piece identification code, which is also a wafer identification code, Wafer ID. In order to realize data traceability, the MES system determines the corresponding sub-work order based on the material code of the loaded material in this embodiment, and binds the material code, the corresponding sub-work order, and the material distribution equipment. After the material box is unloaded after the silicon wafer is collected, the Enterprise Application Platform (EAP) system reports the identification code of the unloaded material box. The MES system obtains the corresponding sub-work order and material batch according to the unloaded equipment, and binds the material box identification with the sub-work order and the material batch.

[0073] In this embodiment, it is further illustrated that, for example, due to the association of the material with the work order requisition, the work order can be obtained according to the material code when loading in the material distribution room. The 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 material and the work order can be traced through the material box id. The battery pieces in the material box will be introduced into the flower basket when loading in the texturing, at which time the EAP will upload the battery pieces in the material box to the MES through the flower basket id. The MES generates a virtual id of the single battery piece according to the work order and the batch associated by the material box id, from which the work order is put into production, and the association of the single semi-finished product and the work order is realized.

[0074] After the production is completed, the cell pieces between processes are loaded into the baskets for tracking, and the work order associated with each cell piece can be obtained according to the basket from the start of the wafering process. Therefore, when the basket is loaded from the boron expansion to the sorting process, the MES will associate the work order of the cell piece in the basket with the equipment, so that the current work order produced by the equipment can be known.

[0075] During the production process, the cell pieces cannot continue to be produced due to process abnormalities, equipment blockage, etc., and need to be reworked and cleaned. Such cell pieces are called rework pieces. When it is monitored that rework pieces exist, the rework quantity corresponding to the rework pieces is recorded in the embodiment, and the current sub-work order being produced is obtained through the MES system when reworking, so as to be filled in by the production personnel. Since the frequency of rework pieces is not high, it needs to be accumulated to a certain quantity before cleaning can be arranged, so the rework pieces cannot be reproduced according to the original work order, and the input quantity and output quantity of the work order need to achieve dynamic conservation, so the rework quantity generated by the rework pieces needs to be recorded.

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

[0077] The association relationship between the work order and the sub-work order in the embodiment can be referred to as shown in Figure 3 After all the sub-work orders are completed, it is determined that the entire work order is completed, the cell piece changes from the production state to the completed state, and after the planned completed quantity is reached, the personnel performs the work order closing operation.

[0078] It should be noted that the cell piece is considered to be completed after being output from the sorting equipment, at which time the cell piece becomes a finished product. At this time, the MES system will calculate the completed quantity of the work order according to the output cell piece, but since the fragments generated during the production process cannot be completely counted, the system cannot automatically complete the work order. Therefore, the work order completion needs the intervention of personnel, and after the personnel operates the work order completion, the system will calculate the fragment quantity generated by the work order according to the fragment calculation formula, which is: fragment quantity = input quantity - output quantity - rework quantity.

[0079] The embodiment generates a work order of a solar cell; associates the work order with a bill of materials according to a product model corresponding to the work order, and issues a material requisition plan; splits the work order into a plurality of sub-work orders based on batch information of main materials of the material requisition plan in response to a material requisition request of a production personnel; respectively produces each sub-work order, and determines completion of the corresponding sub-work order after a cell piece is output from a sorting device; and determines completion of the work order after all sub-work orders are completed, and adjusts state information of the solar cell from a production state to a completion state, thereby increasing a work order management function without changing a traditional solar production mode, managing a whole life cycle of a cell piece from a texturing process to a sorting process, and realizing traceability of a semi-finished product, a scrap piece, a rework piece, and a finished product.

[0080] In addition, the embodiment of the present application further provides a storage medium, wherein the storage medium stores a work order management program, and the work order management program is executed by a processor to realize steps of the work order management method.
