Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method and apparatus for statistical analysis of the operating rate of a stamping production line based on digital means. Background Technology

[0002] Availability is a core indicator for measuring the utilization efficiency of stamping equipment. Its calculation logic is mainly based on lost time, which is defined as the sum of all non-production time that causes the slide to stop during the start-up period. The reasons for downtime include various situations such as malfunctions, material waiting, die change intervals, and operational adjustments. In the stamping industry, production lines can be divided into three categories based on their level of automation: manual lines, semi-automatic lines, and automatic lines. The statistical methods for the availability of different types of production lines vary significantly, and there is no unified statistical standard in the industry. This results in a lack of comparability of availability data for stamping production lines across the entire plant, making it difficult to support lean management and horizontal benchmarking.

[0003] Currently, the industry mainly uses two mainstream methods to count the operating rate of stamping production lines. One is the upper control system dependency method, which is the mainstream statistical method for automated lines. It judges the production status of equipment by collecting signals from the upper control system, such as robot positioning signals and conveyor belt running signals. It can accurately capture downtime events that the control system can perceive. However, this method is highly dependent on the operating environment of highly automated equipment and cannot be applied to manual production lines without robots, conveyor belts and other automated devices, which has the problem of limited application scenarios.

[0004] The second method is manual recording plus simple signal monitoring, which is mainly used in manual and semi-automatic lines. This method relies on operators to manually report shutdown information or monitor the production status through simple signals such as the equipment's "run" indicator light. This not only results in low statistical efficiency but also serious data distortion. It is almost impossible to capture hidden shutdown events such as material waiting and equipment fine-tuning, with a loss time capture rate of less than 50%. At the same time, because some processes in semi-automatic lines are automated while others rely on manual labor, the signal sources are mixed and there is no unified statistical logic, which further leads to low data reliability.

[0005] In addition to the inherent defects of the two mainstream solutions mentioned above, existing stamping production line uptime statistics technologies also have common problems: they have not established a unified judgment standard based on the underlying physical signals of the stamping equipment, but instead use different state judgment logics according to the degree of automation of the production line, which makes it impossible to achieve a unified data standard for the entire plant; they have not designed dynamic judgment rules in combination with the cycle characteristics of different products, which easily misjudges instantaneous actions within the normal cycle as downtime losses, or misses real slide stop events, resulting in low statistical accuracy.

[0006] In summary, there is an urgent need for a statistical method for operating rates that can be adapted to all types of stamping production lines and achieve a unified standard, in order to solve problems such as inconsistent data standards, low rate of capturing hidden downtime, and insufficient statistical accuracy in existing technologies, and to provide reliable data support for lean management of stamping production. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a method and apparatus for statistical analysis of the operating rate of a stamping production line based on digital means, which aims to solve at least one of the problems mentioned in the background art.

[0008] The embodiments of the present invention are implemented as follows: A method for statistically analyzing the operating rate of a stamping production line based on digital means is applied to a data processing layer, which is communicatively connected to a signal acquisition layer and an application display layer. The method includes: The status information of the equipment lubrication system on the stamping production line is acquired by the signal acquisition layer. The start-up time of the stamping production line is obtained by timing the start-up time of the stamping production line based on the status information of the equipment lubrication system. During the stamping production line's operating period, the coordinated status of the clutch and brake dual valves in the stamping production line is monitored in real time to obtain the interval between two actions of the clutch and brake dual valves. Based on the time interval between two actions and the preset beat tolerance time, the loss is selectively excluded or included to obtain the corresponding loss time; The final operating rate of the stamping production line is obtained based on the start-up time and lost time.

[0009] Furthermore, in the aforementioned method for statistically analyzing the operating rate of a stamping production line based on digital means, the step of obtaining the start-up time of the stamping production line by timing the start-up time based on the status information of the equipment lubrication system includes: When the status information of the equipment lubrication system is normal, the start-up timer is triggered. The timer is started when the lubrication system status changes from abnormal to normal. When the lubrication system status changes from normal to abnormal or the equipment loses power, the timer is stopped, and the startup time is obtained. The daily startup time is calculated by summing up multiple startup time periods each day. The normal state of the equipment lubrication system is that the lubrication pressure is greater than or equal to the set threshold and the number of lubrication cycles is greater than or equal to the set threshold.

[0010] Furthermore, the above-mentioned method for calculating the operating rate of a stamping production line based on digital means, before the step of accumulating multiple daily operating time periods to obtain the daily operating time, also includes: Set a threshold for the effective power-on duration; If the boot time is less than the effective boot time threshold, the boot time is removed.

[0011] Furthermore, in the aforementioned method for statistically analyzing the operating rate of a stamping production line based on digital means, the step of selectively excluding or including losses based on the magnitude of the interval between two actions and the preset cycle time tolerance, to obtain the corresponding loss time, includes: When the interval between two actions is less than or equal to the preset clock cycle tolerance time, the lost time is not counted. If the interval between two actions exceeds the preset cycle tolerance time, it is counted as lost time.

[0012] Furthermore, in the above-mentioned method for statistically analyzing the operating rate of a stamping production line based on digital means, the formula for calculating the cycle time tolerance is as follows: Beat tolerance time = 60 seconds / (historical average number of strokes per minute × 0.8).

[0013] Furthermore, in the above-mentioned method for statistically analyzing the operating rate of a stamping production line based on digital means, the formula for calculating the operating rate is as follows: Utilization rate = (Uptime - Lost time) / Planned production time × 100%.

[0014] Furthermore, the aforementioned method for statistically analyzing the operating rate of a stamping production line based on digital means further includes: The application presentation layer displays the utilization rate information, which includes at least a detailed table of lost time, a utilization rate trend analysis chart, and an abnormal utilization rate warning.

[0015] Another objective of this invention is to provide a digital-based stamping production line uptime statistics device, applied to a data processing layer, which is communicatively connected to a signal acquisition layer and an application display layer. The device includes: The acquisition module is used to acquire the status information of the equipment lubrication system on the stamping production line from the signal acquisition layer, and to obtain the start-up time of the stamping production line based on the status information of the equipment lubrication system. The monitoring module is used to monitor the coordinated status of the clutch and brake dual valves in the stamping production line in real time during the stamping production line's operating period, and to obtain the time interval between two actions of the clutch and brake dual valves. The comparison module is used to selectively exclude or include the loss based on the time interval between two actions and the preset beat tolerance time, and to obtain the corresponding loss time. The calculation module is used to obtain the final operating rate of the stamping production line based on the start-up time and loss time.

[0016] Another object of the present invention is to provide a readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the methods described above.

[0017] Another object of the present invention is to provide an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the program, implements the steps of the method described above.

[0018] This invention acquires the lubrication system status information of the stamping production line equipment from the signal acquisition layer, and uses this information to accurately determine the start-up time. During the stamping production line's start-up period, it monitors the clutch and brake dual-valve coordination status in real time and obtains the interval between two actions. Based on the relationship between this interval and the preset cycle time tolerance, it selectively determines whether to include losses to obtain accurate loss time. Finally, based on the start-up time and loss time, it calculates the final operating rate of the stamping production line. By using the lubrication system status information and clutch and brake dual-valve coordination status at the equipment's bottom layer as the core statistical basis, it replaces the traditional upper-level control system signal dependence method and manual recording + simple signal monitoring method. This eliminates the need for reliance on the production line's automation. By eliminating reliance on automation levels, a unified judgment standard based on the underlying physical signals of the equipment is established, eliminating statistical differences between manual, semi-automatic, and automatic lines, and solving the problem of incomparable data across the entire plant. On the other hand, no manual intervention is required to record lost time, achieving fully automatic capture of lost time, significantly improving the capture rate of hidden shutdowns on manual and semi-automatic lines, and solving the problems of missed counts and data distortion. At the same time, through the preset judgment rules of cycle time tolerance, it can accurately distinguish between instantaneous actions within a normal cycle and actual slider stop events, avoiding misjudgments and missed counts, and solving the problem of low statistical accuracy in existing technologies. Ultimately, it provides a unified, accurate, and reliable data foundation for lean management, horizontal benchmarking, and scientific management decision-making throughout the stamping production plant.

[0022] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1 The diagram shown is a logic diagram of the start-up time and loss time statistics in the stamping production line operation rate statistics method based on digital means in an embodiment of the present invention. The loss time is defined as the sum of all non-production state times that cause the slider to stop during the start-up time (regardless of the reason for the stop: failure, material waiting, mold change gap, operation adjustment, etc.).

[0026] Example 1 Please see Figure 2 The figure shows a method for statistical analysis of the operating rate of a stamping production line based on digital means in the first embodiment of the present invention. The method is applied to the data processing layer, which is communicatively connected to the signal acquisition layer and the application display layer. The method includes steps S10 to S13.

[0027] Step S10: Obtain the status information of the equipment lubrication system on the stamping production line collected by the signal acquisition layer, and obtain the start-up time of the stamping production line based on the status information of the equipment lubrication system.

[0028] The signal acquisition layer, as the core layer for data acquisition, uses the KEPServer industrial data acquisition platform as the data acquisition carrier. It collects various key signals from PLCs of multiple brands, including Siemens, AB, Omron, and Mitsubishi, on the stamping production line in real time according to industrial protocols, and transmits the collected signals to the data processing layer in real time and accurately. Meanwhile, an operating rate statistical algorithm runs on the server to clean, transform, and logically judge the raw signals. The application presentation layer can generate visual reports through the FineReport reporting platform to display the operating rate data of each production line.

[0029] Specifically, the equipment lubrication system is a fundamental core component for the normal operation of stamping equipment. Its status information is the core basis for determining whether the stamping production line has entered the start-up state. The signal acquisition layer continuously collects operating parameters such as lubrication pressure and lubrication frequency of the lubrication system and transmits them to the data processing layer. The data processing layer performs professional analysis and logical judgment on this type of status information, and performs the timing work of start-up time according to the preset judgment rules. Finally, the start-up time of the stamping production line is obtained through accurate timing statistics, providing core basic data for the subsequent calculation of the operating rate.

[0030] Step S11: When the stamping production line is in the start-up period, monitor the coordinated status of the clutch and brake dual valves in the stamping production line in real time and obtain the time interval between two actions of the clutch and brake dual valves.

[0031] During the stamping production line's operating hours, the coordinated operation of the clutch and brake dual valves is monitored in real time to obtain the interval between two valve actions. The clutch and brake dual valves are key components in the stamping equipment control system, primarily controlling the coordinated operation of the clutch and brake. Their coordinated operation directly and accurately reflects the actual operating state of the stamping equipment's slide block. When the data processing layer determines that the production line is within the operating time range based on lubrication system status information, it continuously receives the clutch and brake dual valve operation signals transmitted from the signal acquisition layer, performing uninterrupted real-time monitoring of the valves' coordinated operation. Simultaneously, an algorithm accurately calculates the interval between two valve actions, providing a crucial basis for determining subsequent time loss.

[0032] Step S12: Based on the time interval between two actions and the preset beat tolerance time, selectively exclude or include the loss to obtain the corresponding loss time. Based on the interval between two actions and the preset cycle tolerance time, losses are selectively excluded or included to obtain the corresponding loss time. The cycle tolerance time is a pre-set judgment threshold based on the cycle characteristics of different products produced on the stamping production line. Its core function is to accurately distinguish between instantaneous actions within the normal cycle of the stamping equipment and actual slide stop events.

[0033] Specifically, when the interval between two actions is less than or equal to the preset cycle time tolerance, it is not counted as lost time. If the interval between two actions of the clutch and brake dual valves, as calculated by the data processing layer through the algorithm, does not exceed the preset cycle time tolerance, it is determined that this duration is an instantaneous action of the stamping equipment within the normal product production cycle, belonging to normal time consumption in the production process, and not a non-production downtime loss during the start-up period. Therefore, this duration is excluded from the lost time and is not counted or accumulated. When the interval between two actions is greater than the preset cycle time tolerance, it is counted as lost time. If the interval between two actions of the clutch and brake dual valves exceeds the preset cycle time tolerance, it is determined that this duration is a real slide stop of the stamping equipment, belonging to a non-production downtime during the start-up period. This duration will be directly counted as lost time. The data processing layer will continuously and accurately accumulate all durations that meet this judgment condition during the production process. The final accumulated value is the accurate lost time of the stamping production line.

[0034] For example, the formula for calculating the beat tolerance time is: Beat tolerance time = 60 seconds / (historical average number of strokes per minute × 0.8); Among them, the historical average number of punches per minute is the average number of punches per minute obtained by the equipment through big data statistics in the past actual production process when the stamping production line produces the corresponding product. This value can truly and objectively reflect the production cycle characteristics of the corresponding product. The historical average number of punches per minute for different products is accurately statistically calculated based on actual production data. The data processing layer will continuously record, store and update various production data of the stamping production line to realize real-time dynamic updates of the historical average number of punches per minute.

[0035] Step S13: Obtain the final operating rate of the stamping production line based on the start-up time and lost time.

[0036] The data processing layer uses the startup time and loss time obtained through the aforementioned steps as core calculation data. It performs calculations according to a preset standardized calculation formula. Through precise calculation of the two basic data, the operating rate of the stamping production line is finally obtained. This value is directly transmitted to the application display layer for visualization, providing accurate data support for the daily management and lean operation of stamping production.

[0037] For example, the formula for calculating the utilization rate is: Availability = (Uptime - Lost Time) / Planned Production Time × 100%; In addition, in some optional embodiments of the present invention, the application display layer uses the FineReport reporting platform as the core display carrier to perform professional visualization processing and display of various statistical results transmitted by the data processing layer. The displayed content includes at least a loss time detail table, an operating rate trend analysis chart, and an abnormal operating rate warning. At the same time, it can also display other relevant data content such as the whole plant operating rate benchmarking dashboard according to the actual needs of enterprise production management.

[0038] The lost time details table records in detail and accurately all kinds of specific information about each downtime loss of the stamping production line, including equipment number, production line name, downtime start time, downtime end time, downtime duration, and downtime reason, enabling refined tracking and management of each lost time; the operating rate trend analysis chart uses time as the horizontal axis and operating rate value as the vertical axis to intuitively display the operating rate change trend of the stamping production line in different time periods. It can present the daily, weekly, monthly, or even longer-term operating rate fluctuations as needed, making it easy for managers to clearly understand the changing patterns of the production line's operating efficiency; The abnormal operating rate warning is an intelligent reminder function of the application display layer. Managers can preset the operating rate threshold in the application display layer according to the production line's production indicators and management needs. When the operating rate value obtained by the data processing layer is lower than the preset threshold, the application display layer will immediately trigger the warning mechanism and remind the managers through various means such as pop-ups and prompts, so that the managers can promptly discover abnormalities in the production line and take targeted measures.

[0039] All display content in the application presentation layer is dynamically updated in real time, ensuring that managers can grasp the operating rate information of the stamping production line in a timely, accurate and comprehensive manner.

[0040] In summary, the digital-based method for calculating the operating rate of a stamping production line in the above embodiments of the present invention obtains the lubrication system status information of the stamping production line equipment collected by the signal acquisition layer, and uses this as a basis to calculate the accurate start-up time. During the start-up period of the stamping production line, the coordinated state of the clutch and brake dual valves of the stamping production line is monitored in real time, and the interval between two actions is obtained. Then, based on the relationship between the interval between the two actions and the preset cycle tolerance time, it is selectively determined whether to include the loss to obtain the accurate loss time. Finally, the final operating rate of the stamping production line is calculated based on the start-up time and the loss time. By using the lubrication system status information and the coordinated state of the clutch and brake dual valves at the equipment bottom layer as the core statistical basis, it replaces the traditional upper-level control system signal dependence method and manual recording + simple signal method. The monitoring method, on the one hand, eliminates the reliance on the degree of automation of the production line, establishes a unified judgment standard based on the underlying physical signals of the equipment, eliminates the statistical differences between manual, semi-automatic, and automatic lines, and solves the problem of incomparable data across the entire plant. On the other hand, it eliminates the need for manual participation in recording lost time, achieving fully automatic capture of lost time, significantly improving the capture rate of hidden shutdowns on manual and semi-automatic lines, and solving the problems of missed counts and data distortion. At the same time, through the preset judgment rules of cycle time tolerance, it can accurately distinguish between instantaneous actions within a normal cycle and actual slider stop events, avoiding misjudgments and omissions, and solving the problem of low statistical accuracy in existing technologies. Ultimately, it provides a unified, accurate, and reliable data foundation for lean management, horizontal benchmarking, and scientific management decision-making across the entire stamping production plant.

[0041] Example 2 This embodiment also proposes a method for statistically analyzing the operating rate of a stamping production line based on digital means. The difference between this method and the method in Embodiment 1 is that the latter method is based on digital means. The steps for obtaining the start-up time of the stamping production line by timing the start-up time based on the status information of the equipment lubrication system include: When the status information of the equipment lubrication system is normal, the start-up timer is triggered. The timer is started when the lubrication system status changes from abnormal to normal. When the lubrication system status changes from normal to abnormal or the equipment loses power, the timer is stopped, and the startup time is obtained. The daily startup time is calculated by summing up multiple startup time periods each day. The normal state of the equipment lubrication system is that the lubrication pressure is greater than or equal to the set threshold and the number of lubrication cycles is greater than or equal to the set threshold.

[0042] The core trigger condition for timing is whether the equipment's lubrication system is in normal condition. The normal condition of the equipment's lubrication system is defined as lubrication pressure ≥ set threshold and lubrication frequency ≥ set threshold. Different models and specifications of stamping equipment can set specific lubrication pressure thresholds in advance according to their own equipment parameters and actual production needs. The number of lubrication frequencies is strictly determined according to the industry operating standards of stamping equipment and the original manufacturer's instructions. Only when both the lubrication pressure and the number of lubrication frequencies meet the standard will the equipment's lubrication system be judged to be in normal condition.

[0043] When the lubrication system status is normal, the start-up timer is triggered. After receiving the lubrication system status information such as lubrication pressure and lubrication frequency from the signal acquisition layer, the data processing layer first performs a professional and comprehensive analysis of this information, strictly determining whether it meets all the requirements for a normal state. If all requirements are met, the start-up timer immediately begins. When the lubrication system status changes from abnormal to normal, the timer is started. The data processing layer continuously monitors the lubrication system status in real time using algorithms. When it accurately captures the transition point from abnormal to normal, the timer immediately starts counting, and this transition point is the start time of this start-up. When the lubrication system status changes from normal to abnormal or the equipment loses power, the timer stops, and the start-up time is obtained. During the timer's operation, the data processing layer continuously and synchronously monitors the lubrication system status changes and the equipment's power supply status. If either the lubrication system status changes from normal to abnormal or the equipment loses power, the timer immediately stops. The duration from start to stop of the timer is the single start-up time of this stamping production line. The total uptime for the day is calculated by adding up multiple uptime periods throughout the day. During the actual production process, the stamping production line will experience multiple uptimes and downtimes due to various production factors. The data processing layer will accurately record and store the single uptime of each time during the day. After the production work is completed for the day, all the single uptimes of the day will be added up, and the total uptime of the stamping production line for that day will be calculated.

[0044] Furthermore, before accumulating multiple daily power-on periods to derive the daily power-on time, a professional data verification process is included. By setting effective power-on duration thresholds and corresponding filtering rules, the interference of short-term device fluctuations on the power-on time statistics is effectively eliminated, further improving the accuracy and reliability of the power-on time statistics.

[0045] Secondly, a daily power-on time threshold is set. When the total power-on time in a day is less than 30 minutes, there will be no power-on time for that day, and the lost time will no longer be counted.

[0046] In summary, the digital-based method for calculating the operating rate of a stamping production line in the above embodiments of the present invention obtains the lubrication system status information of the stamping production line equipment collected by the signal acquisition layer, and uses this as a basis to calculate the accurate start-up time. During the start-up period of the stamping production line, the coordinated state of the clutch and brake dual valves of the stamping production line is monitored in real time, and the interval between two actions is obtained. Then, based on the relationship between the interval between the two actions and the preset cycle tolerance time, it is selectively determined whether to include the loss to obtain the accurate loss time. Finally, the final operating rate of the stamping production line is calculated based on the start-up time and the loss time. By using the lubrication system status information and the coordinated state of the clutch and brake dual valves at the equipment bottom layer as the core statistical basis, it replaces the traditional upper-level control system signal dependence method and manual recording + simple signal method. The monitoring method, on the one hand, eliminates the reliance on the degree of automation of the production line, establishes a unified judgment standard based on the underlying physical signals of the equipment, eliminates the statistical differences between manual, semi-automatic, and automatic lines, and solves the problem of incomparable data across the entire plant. On the other hand, it eliminates the need for manual participation in recording lost time, achieving fully automatic capture of lost time, significantly improving the capture rate of hidden shutdowns on manual and semi-automatic lines, and solving the problems of missed counts and data distortion. At the same time, through the preset judgment rules of cycle time tolerance, it can accurately distinguish between instantaneous actions within a normal cycle and actual slider stop events, avoiding misjudgments and omissions, and solving the problem of low statistical accuracy in existing technologies. Ultimately, it provides a unified, accurate, and reliable data foundation for lean management, horizontal benchmarking, and scientific management decision-making across the entire stamping production plant.

It is applied to the data processing layer, which is communicatively connected to both the signal acquisition layer and the application display layer. The device includes: The acquisition module 100 is used to acquire the status information of the equipment lubrication system on the stamping production line acquired by the signal acquisition layer, and to obtain the start-up time of the stamping production line based on the status information of the equipment lubrication system. The monitoring module 200 is used to monitor the coordinated status of the clutch and brake dual valves in the stamping production line in real time during the start-up period of the stamping production line, and to obtain the time interval between two actions of the clutch and brake dual valves. The comparison module 300 is used to selectively exclude or include the loss based on the size of the interval between two actions and the preset beat tolerance time, so as to obtain the corresponding loss time. The calculation module 400 is used to obtain the final operating rate of the stamping production line based on the start-up time and loss time.
