[0022] As described in the above steps S1-S8, PCB is an electronic component that provides electrical connection and mechanical support for electronic components. With the development of miniaturization and high performance of electronic equipment, the production process of PCB is becoming more and more complicated, and the requirements for production management are also increasing. Traditional extensive management is difficult to meet the needs of high-precision and high-reliability PCB production. Therefore, a multi-region management method came into being. It can more accurately control each link in the production process by subdividing the production process area. This management method aims to improve production efficiency, ensure product quality, optimize resource allocation, and better deal with complex situations in the production process. At present, in the production process of PCB, the order quantity often changes. When the order quantity changes, in order to achieve the expected production target, it is usually necessary to allocate production tasks according to the production capacity of the production line. However, this allocation method has the problem that the production tasks do not match the production capacity of different production process areas in the production line, resulting in the problem that the final production results do not meet the production expectations. The present invention obtains multiple production line information and multiple production monitoring information of PCB production, wherein the production line information refers to the key production process areas that constitute the complete PCB production process, mainly including the graphic process area, the lamination process area, the surface process area and the molding process area; the production monitoring information refers to the detailed record of the product processing conditions in each production line and each production process area during the PCB production process; then, according to the production monitoring information, the in-and-out time information and the in-and-out quantity information are obtained, wherein the in-and-out time information refers to the specific time when the product enters and exits each production line and each production process area; the in-and-out quantity information refers to the specific quantity of the product entering and exiting each production line and each production process area; the in-and-out time information and the in-and-out quantity information can accurately reflect the flow of products on the production line; then, the in-and-out time information and the in-and-out quantity information are used to calculate the first production efficiency of each production process area and the online product of each production line Production progress value, where the first production efficiency refers to the individual production efficiency of each production process area on each production line, and the online product production progress value refers to the production progress of the product in the production state in a single production process area. The online product production progress value can intuitively present the current progress of the product on the production line, and then use the in-and-out time information, in-and-out quantity information and online product production progress value to calculate the second production efficiency of each production line, where the second production efficiency refers to the overall production efficiency of each production line. The calculation of the second production efficiency comprehensively considers the production efficiency of each production process area on each production line and the current production progress of each production process area, thereby providing a more accurate indicator for the overall production efficiency evaluation of the production line. Then, the first allocation quantity of each production line is obtained according to the order change information and the second production efficiency, where the order change information refers to the relevant information that the order content has changed due to various factors after the customer places an order.The first allocated quantity refers to the specific production quantity allocated to each production line according to the order change information, so as to facilitate the timely adjustment of the task allocation of the production line according to the changes in order demand, and avoid production chaos or waste of resources due to order changes. Then, the second allocated quantity is calculated according to the first production efficiency, product transfer efficiency and the first allocated quantity. Among them, the product transfer efficiency refers to the efficiency of a production process area of ​​a production line in transferring products to the subsequent production process areas of the same or another production line. The second allocated quantity refers to the specific quantity of a production process area of ​​a production line in transferring products to the subsequent production process areas of the same or another production line. By analyzing the transfer efficiency of products between different production process areas, combined with the production efficiency of different production process areas and the initial allocation quantity of products for each production line, the production task allocation is further optimized so that production The task allocation is more scientific and reasonable, avoiding the impact of transfer efficiency issues on the overall production progress, improving the consistency and coordination of the production process, and then obtaining the expected delivery cycle based on the second allocation quantity and the first production efficiency. The expected delivery cycle refers to the time required for all production lines to jointly realize the specified product processing quantity in the order change information. Finally, the expected delivery cycle is compared with the expected value to determine whether the current production task allocation meets the expected requirements. If the expected delivery cycle is greater than the expected value, it is determined that the current production task allocation does not meet the expected requirements. By adjusting the key factor of product transfer efficiency, the production task allocation is re-optimized to ensure that the expected production requirements are finally met. Through this dynamic adjustment mechanism, production management can be continuously optimized according to actual conditions. Through iterative adjustments, a production plan that meets expectations can be gradually found, effectively solving the problem of delivery delays and ensuring the realization of production goals. ,

[0023] In one embodiment, the step of calculating the first production efficiency of each production process area and the online product production progress value of each production line according to the in-and-out time information and the in-and-out quantity information includes: S31, obtaining the number of completed products in each production process area according to the in-and-out quantity information; S32, obtaining the single-area product processing time of each production process area according to the storage and warehousing time information; S33, obtaining a first production efficiency of each production process area according to the number of completed products in each single area and the corresponding processing time of the single area products; S34, obtaining a weight coefficient corresponding to each production process area; S35. Calculate the online product production progress value of each production line according to the completed quantity of each single-area product and the weight coefficient, wherein the calculation formula is: ; Among them, Z irepresents the production progress value of the online product of the i-th production line, y ij represents the number of products completed in the jth production process area of ​​the i-th production line, w ij represents the weight coefficient corresponding to the jth production process area in the i-th production line, n i Represents the number of production process areas in the i-th production line.

The single production process area can be individually evaluated by the number of completed single-area products and the processing time of single-area products. Then, the first production efficiency of the corresponding production process area can be obtained by dividing the number of completed single-area products by the corresponding single-area product processing time. The first production efficiency is a quantitative evaluation of the production capacity of each production process area. At the same time, taking into account the different importance of different production process areas in the entire production line, by obtaining the weight coefficient corresponding to each production process area, the contribution of each production process area to the overall production progress of the production line can be more accurately reflected. Finally, the number of completed products in each production process area and its corresponding weight coefficient are comprehensively considered to calculate the online product production progress value of the entire production line. The online product production progress value can be used for the accurate calculation of the second production efficiency of each subsequent production line.

[0025] In one embodiment, the step S4 of calculating the second production efficiency of each production line according to the in-and-out time information, the in-and-out quantity information and the online product production progress value includes: S41, obtaining the total quantity of product input and the total quantity of product completed for each production line according to the in-and-out quantity information; S42, obtaining the number of online products of each production line according to the total number of product inputs and the total number of product completions; S43, obtaining the single-line product processing time of each production line according to the storage and out-of-warehouse time information; S44, calculating the second production efficiency of each production line according to the total number of products completed, the number of online products, the production progress value of online products and the processing time of single-line products of each production line, wherein the calculation formula is: ; Among them, E i represents the second production efficiency of the i-th production line, M i represents the total number of products completed on the i-th production line, N irepresents the number of online products on the i-th production line, Z i represents the production progress value of the online product of the i-th production line, T i Represents the single-line product processing time of the i-th production line.

[0026] As described in the above steps S41-S44, the present invention obtains the number of online products of each production line according to the difference between the total number of product inputs and the total number of product completions, wherein the total number of product inputs refers to the number of products input into a single production line, the total number of product completions refers to the number of products processed by the corresponding production line, and the number of online products refers to the number of products that have been put into the production line but have not yet been processed. Then, the second production efficiency of each production line is calculated according to the total number of product completions of each production line, the number of online products, the online product production progress value and the single-line product processing time according to a specific formula, wherein the single-line product processing time refers to the time that a single production line has processed the product, the total number of product completions in the specific formula reflects the completed production results, and the online product number and the production progress value take into account the status of the products on the current production line. Through this comprehensive calculation method, the actual production capacity of the production line can be more comprehensively and accurately reflected.

[0027] In one embodiment, the step S5 of acquiring the first allocation quantity of each production line according to the order change information and the second production efficiency includes: S51, obtaining production defect information of PCB production according to the production monitoring information, and obtaining the number of production defect information according to the production defect information; S52, obtaining the total inventory of products according to the total completed quantity of the products of each production line, and obtaining the completed quantity of products according to the total inventory of products and the quantity of production defects; S53, obtaining the order change quantity according to the order change information, and obtaining the product to-be-processed quantity according to the order change quantity and the product completed quantity; S54. Obtain a first allocated quantity for each production line according to the number of products to be processed and each second production efficiency.

[0028] As described in the above steps 51-S54, in the present invention, the number of production defects is obtained according to the production defect information, wherein the production defect information refers to the situation of products with quality problems in the production process, and the number of production defects refers to the number of products with quality problems in the production process. The number of completed products is obtained according to the difference between the total inventory of products and the number of production defects, wherein the total inventory of products refers to the sum of the number of products that have been processed by all production lines, and the number of completed products refers to the sum of the number of qualified products that have been processed by all production lines after removing the defective products. Then, the number of products to be processed is obtained according to the difference between the order change quantity and the completed number of products, wherein the number of products to be processed refers to the number of products that still need to be processed. Finally, the first allocation quantity of each production line is obtained according to the number of products to be processed and the second production efficiency, wherein the calculation formula of the first allocation quantity of a single production line is: first allocation quantity=number of products to be processed*(second production efficiency of a single production line / sum of second production efficiencies of all production lines). This allocation method can make full use of the production capacity of each production line, which is conducive to improving the overall production efficiency.

[0029] In one embodiment, the step S6 of calculating the second allocation quantity according to the first production efficiency, the product transfer efficiency and the first allocation quantity comprises: S61. Calculate the blending production efficiency of each production process area according to the first production efficiency and the product transfer efficiency, wherein the calculation formula is: ; Among them, S ij represents the coordinated production efficiency of the jth production process area in the i-th production line, e hf represents the product transfer efficiency of the fth production process area in the hth production line to the jth production process area in the ith production line, r ij represents the first production efficiency of the jth production process area in the i-th production line; S62, calculating a second allocation quantity according to the blending production efficiency and the first allocation quantity, wherein the calculation formula is: ; Among them, X vij represents the second allocation quantity of the product transferred from the vth production line to the jth production process area in the ith production line, P i represents the first allocation quantity of the i-th production line, S ij It represents the harmonic production efficiency of the jth production process area in the i-th production line, and n represents the number of production process areas.

[0030] As described in the above steps S61-S62, the present invention combines the first production efficiency and the product transfer efficiency to calculate the blending production efficiency through a specific formula, wherein the blending production efficiency refers to an indicator that comprehensively considers the production capacity of the production process area itself and the product transfer efficiency between different production process areas. The first production efficiency represents the production capacity of the production process area itself, and the product transfer efficiency represents the smoothness of product transfer between production process areas. Then, the second allocation quantity is calculated based on the blending production efficiency and the first allocation quantity. Allocation based on the blending production efficiency can make full use of the comprehensive advantages of each production process area. The purpose is to ensure that each production process area can undertake a reasonable amount of production tasks according to its actual capacity, so that the distribution of production tasks between areas is more reasonable, which helps to reduce waiting time and resource waste in the production process, thereby improving the production efficiency of the entire production line.

[0031] In one embodiment, the step S7 of obtaining the estimated delivery period according to the second allocated quantity and the first production efficiency includes: S71, obtaining the production demand time of each production process area according to the second allocated quantity and the corresponding first production efficiency of each production process area; S72, obtaining the required transfer time of each production process area according to the second allocated quantity and the corresponding product transfer efficiency of each production process area; S73, sorting the production demand time and the corresponding transfer demand time of each production process area according to size, taking the larger value as the single-area completion demand time, and obtaining the single-line completion demand time according to the multiple single-area completion demand times in each production line; S74, sorting the plurality of single-line completion demand times by size, and taking the larger value as the estimated delivery cycle.

[0032] As described in the above steps S71-S74, the present invention obtains the production demand time of each production process area by dividing the second allocated quantity of each production process area by the corresponding first production efficiency, and obtains the transfer demand time of each production process area by dividing the second allocated quantity of each production process area by the corresponding product transfer efficiency. For each production process area, since the completion of the product depends not only on production but also on transfer, the larger value of the production demand time and the transfer demand time is taken as the single-area completion demand time, wherein the single-area completion demand time refers to the time required for a single production process area to complete the processing of a specified number of products. On this basis, the single-area completion demand times of multiple production process areas in a production line are further integrated to obtain the single-line completion demand time, wherein the single-line completion demand time refers to the time required for a single production line to complete the processing of a specified number of products. Finally, the single-line completion demand times of different production lines are compared, and the maximum value is selected as the estimated delivery cycle, which is an overall estimate of the delivery time of the entire PCB production.
