In this execution operation, the production line accessory supply equipment, the corresponding index item information, and the absolute values of the supply amount of the accessories may be used to supply the accessories on different production line equipment, so as to ensure that each production line manufacturing equipment with insufficient supply amount of the accessories may meet the required supply amount of the accessories during the execution of the manufacturing task to realize the automatic and reasonable allocation of resources.

In some embodiments, when the storage amount of the accessories of the production line accessory supply equipment is less than the total amount of the required accessories, indicating that the storage amount of the accessories of the production line accessory supply equipment is insufficient, which includes following execution operations.

When the storage amount of the accessories of the production line accessory supply equipment is less than the total amount of required accessories, a supply difference of the accessories may be obtained using the total amount of the accessories minus the storage amount of the accessories.

Based on the supply difference of the accessories, the supply instructions of the accessories may be sent to the sub-platforms of the management platform corresponding to the production line accessory supply equipment by the service platform, and accessories with an amount being greater than or equal to the supply difference of the accessories may be supplied by the production line accessory supply equipment after obtaining the supply instructions. After completing the supplying, a supply step may be executed by the production line accessory supply equipment when the storage amount of the accessories of the production line accessory supply equipment is greater than or equal to the total amount of the accessories.

where S means the single allocation amount of the accessories for each production line manufacturing equipment, S′ means the supply amount of the accessories of the corresponding production line manufacturing equipment, S_totalmeans the allocation amount of the accessories, and T_totalmeans the total amount of the accessories.

After integrating the index item information of the corresponding production line manufacturing equipment and the single allocation amount of the accessories, the data packages may be packaged and sent to the sub-platforms of the management platform corresponding to the production line accessory supply equipment, and then after packaging through the main platform of the management platform, the data packages may be sent to the production line accessory supply equipment through the sensor network platform.

After obtaining the data packages, the accessories of the corresponding production line manufacturing equipment may be retrieved by the production line accessory supply equipment based on the index item information of the corresponding production line manufacturing equipment and the single allocation amount of the accessories.

After completing the retrieving, a supply step may be executed by the production line accessory supply equipment when the storage amount of the accessories of the production line accessory supply equipment is greater than or equal to the total amount of the accessories.

For further illustration, for example, the supply amount of the accessories of each production line manufacturing equipment corresponding to five production line manufacturing equipment are 35, 42, 73, 55, and 38, respectively, then the allocation amount of the accessories is obtained as 243 by adding the five supply amount of the accessories, and the single allocation amount of the accessories for each production line manufacturing equipment is as follows.

According to the above formula (1), the single allocation amount of the accessories for each production line manufacturing equipment are 34.02, 40.82, 70.95, 53.46, and 36.93, respectively.

When the single allocation amount of the accessories of the production line manufacturing equipment has a decimal, because the single amount cannot be split, the decimal may be discarded and the integer may be used as the single allocation amount of the accessories to ensure that the accessories corresponding to the production line equipment are sufficient after the allocation. Therefore, the single allocation amount of the accessories for each production line manufacturing equipment are finally 34, 40, 70, 53, and 36, respectively.

In some embodiments, the sub-platforms of the management platform may determine the consumption of the etching solution based on the unit etching speed and the multiple relationship between the unit consumption of the etching solution and the etching time. For example, the speed of etching the circuit board is 100 μm/min, and the thickness of the circuit board to be etched is 200 μm, so the etching time required for etching the circuit board is 2 min. Under the condition that the unit consumption of the etching solution is 50 mL/min, the consumption of the etching solution for etching each circuit board is 100 mL.

In some embodiments of the present disclosure, the unit etching speed and the unit consumption of the etching solution are determined, and then the consumption of the etching solution is determined based on the unit etching speed and the unit consumption of the etching solution, causing that the sub-platforms of the management platform may more flexibly determine the consumption of the etching solution at a certain time point in the future.

FIG. 4 is an exemplary schematic diagram of function and training of a first model according to some embodiments of the present disclosure. The process illustrated in the process 400 may be performed by the sub-platforms of the management platform. In some embodiments, the process illustrated in the process 400 may include the following contents.

In some embodiments, the information of the etching solution 410 and the working parameters of the etching equipment 420 may be input into a first model 440 by the sub-platforms of the management platform, and the first model 440 may output the unit etching speed 450-1 and the unit consumption of the etching solution 450-2.

The RNN extracts the features of each time point, and then predicts the unit etching speed and unit consumption of the etching solution for multiple future time periods based on the features of each time point.

In some embodiments, the equipment data collectors may also collect specification information of the circuit boards 430, and the input of the first model may further include specification information of the circuit boards 430, and the circuit boards may be an etched circuit board.

It may be appreciated that the size of the circuit boards will affect the volume of the required etching solution, and the thickness of the copper foil layer will affect the required etching time of the circuit boards. For example, the larger the circuit boards are, the more etching solution required by the spray device is; the thicker the copper foil layer is, the longer the etching time is. For the production line for etching circuit boards, it will involve the process of outputting the etched circuit boards and inputting the circuit boards to be etched. When the circuit boards are replaced, the etching solution is not used, so the unit consumption of the etching solution and the unit etching speed are predicted based on the etching time after removing the replacement time, which makes the prediction result more accurate.

In some embodiments, the sub-platforms of the management platform may use the information of the marked sample etching solution and the working parameters of the sample etching equipment as a first training sample 470, input the first training sample 470 into an initial first model 460 for training to obtain the first model 440.

For example, the sub-platforms of the management platform may construct a loss function by the labels and the results of the initial first model, and iteratively update the parameters of the initial first model based on the loss function. When the loss function of the initial first model satisfies the condition, the model training is completed, and the trained first model is obtained. The conditions may include the convergence of the loss function, the number of iterations reaching a threshold, etc. Methods for training the first model include, but are not limited to, gradient descent, regularization, and conjugate gradient methods, etc.

In operation 510, determining a residual etching solution in the future time period based on a predicted consumption of the etching solution.

The residual etching solution may refer to the amount of the etching solution remaining in the etching equipment.

In some embodiments, the equipment data collectors may collect the current amount of etching solution of the etching equipment, the management device may determine the difference between the current amount of the etching solution and the predicted consumption of the etching solution as the residual etching solution.

In operation 520, if the residual etching solution is less than the threshold, determining that the etching equipment needs to deliver the etching solution.

The threshold may be a minimum residual etching solution for supplying the etching solution into the etching equipment, which is preset according to experience or operational requirements. In some embodiments, the threshold may be adjusted based on the delivery speed. For example, the faster the delivery speed is, the lower the threshold is; the slower the delivery speed is, the higher the threshold is.

In some embodiments of the present disclosure, it is determined whether it is necessary to deliver etching solution based on the relationship between the residual etching solution and the threshold, which can avoid resource waste caused by delivering at any time and also avoid production accidents caused by untimely delivering.

In operation 530, determining the threshold based on the difference between the unit consumption of the etching solution and the delivery speed.

The delivery speed may reflect a delivery speed when the production line accessory supply equipment supplies the etching solution for the etching equipment. In some embodiments, the delivery speed may be expressed in terms of a unit speed or a total delivery time. For example, the amount of the etching solution supplied by the production line accessory supply equipment per minute. For another example, the time taken by the production line accessory supply equipment to supply the required etching solution to the etching equipment after receiving the delivery instruction.

In some embodiments, the main platform of the management platform may determine the delivery speed through historical statistics based on the count of the plurality of etching equipment that need to be delivered and the total amount of the plurality of etching equipment that need to be delivered.

The historical data may be the data for supplying the etching solution to the etching equipment in the history of the production line accessory supply equipment. The historical data may include the delivery amount of the etching solution, and the delivery time of the etching solution, etc.

In some embodiments, the historical statistics may include the historical delivering total amount and the historical delivery time, and the delivery speed may be determined based on the multiple relationship between the historical delivering total amount and the historical delivery time. For example, the delivery speed is a value obtained by dividing the historical delivering total amount by the historical delivery time.

In some embodiments of the present disclosure, the delivery speed is determined by historical statistics, causing the obtained delivery speed more accurate.

In some embodiments, the sub-platforms of the management platform may determine the threshold based on the difference between the delivery speed and the unit consumption of the etching solution, the etching time that is maintained by the residual etching solution, and a preset remaining amount. The preset remaining amount may be an amount that the etching solution in the preset etching equipment should be larger than. For example, threshold=|delivery speed−unit consumption of etching solution|×unit remaining amount of etching solution/unit consumption of etching solution+preset remaining amount.

In some embodiments, the threshold may be also related to the confidence of the first model. For example, if the confidence level of the model is low, it indicates that the result output by the model has a large error, so the threshold may be adjusted upwards. The confidence of the model may refer to a degree of confidence in the correctness of the output of the model to solve a certain problem. In some embodiments, the confidence may be determined based on historical data. For example, compare the actual unit consumption of the etching solution and unit etching speed with the predicted unit consumption of the etching solution and the predicted unit etching speed. Exemplarily, the sub-platforms of the management platform may determine the confidence based on the confidence interval formed by the actual etching speed and the predicted unit etching speed. Exemplarily, when the length of the confidence interval is greater than 10 mL, it indicates that the confidence of the model is low, when the length of the confidence interval is less than 5 mL, it indicates that the confidence of the first model is high. For another example, the sub-platforms of the management platform may determine a confidence based on the difference between the expected actual unit consumption of the etching solution and the predicted unit consumption of the etching solution by the first model.

In operation 540, determining the delivery amount of the etching solution by the sub-platforms of the management platform based on the difference between the residual etching solution and the threshold.

In some embodiments, the sub-platforms of the management platform may determine the sum of the difference between the residual etching solution and the threshold and the preset remaining amount as the delivery amount of the etching solution. The sub-platforms of the management platform may also determine the delivery amount of the etching solution in other feasible ways.

Further, the sub-platforms of the management platform may also determine a priority level of the delivering based on the delivery time and the residual etching solution and deliver the etching equipment in the order of the priority level.
