DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1 As shown, the first aspect of the present invention provides a method for testing the conveying performance of a stamping sheet material conveying equipment, comprising: marking the sheets conveyed by the stamping sheet material conveying equipment as target sheets, monitoring the operating data of the stamping sheet material conveying equipment, and obtaining an operating accuracy evaluation index of the stamping sheet material conveying equipment after processing, wherein the operating data of the stamping sheet material conveying equipment includes transportation speed data and transportation position data of each target sheet material.

[0039] The vibration data of each target sheet material is collected, and the operating noise data of the stamping sheet material feeding equipment is obtained, and the operating stability evaluation index of the stamping sheet material feeding equipment is obtained through comprehensive analysis.

[0040] The environmental data of the stamping sheet material conveying equipment is monitored, and the environmental interference value of the stamping sheet material conveying equipment is obtained after processing. According to the operation accuracy evaluation index and operation stability evaluation index of the stamping sheet material conveying equipment, a comprehensive analysis is performed to obtain the comprehensive transmission performance evaluation value of the stamping sheet material conveying equipment.

[0041] The performance evaluation is carried out according to the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment, and the evaluation results are obtained and feedback is provided.

[0042] Specifically, the transportation speed data of each target sheet material is specifically processed as follows: the transportation speed data of each target sheet material, including the maximum feeding speed, acceleration performance parameters and deceleration performance parameters of each target sheet material, is comprehensively analyzed to obtain the transportation speed abnormality evaluation index of each target sheet material.

[0043] In a specific embodiment, the maximum feeding speed of each sheet material can be obtained through a speed sensor. The maximum feeding speed is a key indicator for measuring the abnormal evaluation index of the transportation speed. It must be maintained within a certain range and should not be too large or too small. If it is too large, it will lead to increased energy consumption and a subsequent increase in operating costs. If it is too small, it will be inefficient and difficult to meet the performance standards.

[0044] It should be understood that the acceleration performance parameter in this embodiment refers to the acceleration from rest to maximum speed, and the deceleration performance parameter refers to the acceleration from maximum speed to stop. The acceleration performance parameter and the deceleration performance parameter can be monitored by an acceleration sensor. By monitoring and analyzing the acceleration performance parameter and the deceleration performance parameter, the reliability and scientificity of the transportation speed data can be improved.

[0045] In a specific embodiment, the preset reference standard maximum feeding speed, the allowable deviation maximum feeding speed, the reference standard acceleration performance parameter, the allowable deviation acceleration performance parameter, the reference standard deceleration performance parameter and the allowable deviation deceleration performance parameter are obtained from the stamping sheet feeding equipment database, and the transportation speed abnormality evaluation index of each target sheet is obtained by comprehensive analysis. The specific numerical expression is:

[0048] Table 1 Example of transport speed abnormality assessment index data

[0049]

[0050] As shown in Table 1, in a specific embodiment, there are five groups of data, each group of data is the same, wherein: =2m / s, The target sheet material transportation speed abnormality evaluation index is determined by the maximum feeding speed, acceleration performance parameter, and deceleration performance parameter. In this embodiment, the reference standard maximum feeding speed is 2m / s, and the reference standard acceleration performance parameter is 8m / s. , the reference standard deceleration performance parameter is 6m / . When the difference between the maximum feeding speed, acceleration performance parameters and deceleration performance parameters and the reference standard value is larger, the corresponding target sheet material's transportation speed abnormality evaluation index is larger, indicating that the target sheet material's transportation speed performance is lower. In this embodiment, the three important factors of maximum feeding speed, acceleration performance parameters and deceleration performance parameters are considered at the same time, which provides a more comprehensive perspective for the evaluation. By standardizing the maximum feeding speed, acceleration performance parameters and deceleration performance parameters, it is ensured that they are compared at the same magnitude, thereby improving the fairness and comparability of the evaluation. By weighting the influence of the maximum feeding speed, acceleration performance parameters and deceleration performance parameters, their relative importance in the evaluation index is reflected, and the weights of different factors can be adjusted according to different needs, so that the model has good adaptability. The closer the value of the target sheet material's transportation speed abnormality evaluation index is to 0, the lower the target sheet material's transportation speed abnormality evaluation index is, that is, the closer it is to the ideal state.

[0051] In this embodiment, the value range of the transport speed abnormality assessment influencing factor corresponding to the maximum feeding speed, acceleration performance parameters, and deceleration performance parameters is between 0 and 1. By adjusting the value of the influencing factor, a personalized transport speed abnormality index assessment can be performed for different equipment or different target sheets.

[0052] It should be understood that in this embodiment, the relationship between the maximum feeding speed, acceleration performance parameters, deceleration performance parameters and the transport speed abnormality evaluation index in the historical data is used to construct a mapping set of the maximum feeding speed, acceleration performance parameters, deceleration performance parameters and the corresponding transport speed abnormality evaluation influencing factors, and the real-time maximum feeding speed, acceleration performance parameters and deceleration performance parameters are input to obtain the corresponding transport speed abnormality evaluation influencing factors from the mapping set.

[0053] It should be understood that the transport speed abnormality evaluation index of each target sheet material in this embodiment is used to quantitatively evaluate the degree of abnormality of the transport speed of each target sheet material.

[0054] This expression can identify abnormal sheets based on the degree to which the maximum feeding speed, acceleration performance parameters and deceleration performance parameters of each sheet deviate from the standard. By quantifying the deviation, the processing process of those sheets with low scores can be improved in a targeted manner, thereby optimizing the efficiency and stability of the overall production line.

[0055] Specifically, the operation accuracy evaluation index of the stamping sheet material feeding equipment is obtained by processing, and the specific processing process is: the transportation position data of each target sheet material includes the real-time position of the center point of each target sheet material.

[0056] Deploy several transportation time monitoring points, obtain the center point position of each target sheet at each transportation time monitoring point, obtain the estimated center point position of each transportation time monitoring point, collect the straight-line distance between the center point position of each target sheet at each transportation time monitoring point and the estimated center point position, and mark it as the deviation distance of each target sheet at each transportation time monitoring point.

[0057] According to the deviation distance of each target sheet at each transportation time monitoring point and the transportation speed abnormality evaluation index of each target sheet, a comprehensive analysis is conducted to obtain the operation accuracy evaluation index of the stamping sheet feeding equipment. The operation accuracy evaluation index of the stamping sheet feeding equipment is used to quantitatively evaluate the accuracy of the stamping sheet feeding equipment in transmitting the sheet.

[0058] It should be understood that in this embodiment, a position sensor and a rangefinder should be used to measure the deviation distance of each target sheet at each transportation time monitoring point to ensure the accuracy of the data. The operation accuracy evaluation index of the stamping sheet feeding equipment is specifically expressed as:

[0059] ;

[0060] in, It represents the running accuracy evaluation index of the punching sheet feeding equipment, e represents the natural constant, It represents the deviation distance of the i-th target sheet at the j-th transportation time monitoring point, Indicates the set critical deviation distance, represents the abnormal evaluation index of the transportation speed of the i-th target sheet, Indicates the impact factor of the operation accuracy assessment corresponding to the set deviation distance, It represents the operation accuracy evaluation influencing factor corresponding to the set transportation speed, i represents the number of each target sheet, i=1,2,3,...,p, p represents the total number of target sheets, j represents the number of each transportation time monitoring point, j=1,2,3,...,q, q represents the total number of transportation time monitoring points.

[0061] It should be understood that in this embodiment It is used to quantify the position accuracy of the target sheet. The value range of the operation accuracy assessment impact factor corresponding to the deviation distance and the transportation speed abnormal assessment index is between 0 and 1. The larger the deviation distance, the larger the transportation speed abnormal assessment index, and the lower the corresponding operation accuracy assessment index. By adjusting the value of the impact factor, the user can adjust the relative importance of the deviation distance and speed to the assessment index according to the specific situation.

[0062] It should be understood that in this embodiment, a mapping set of deviation distance, transport speed abnormality assessment index and corresponding operation accuracy assessment influencing factors is constructed through the relationship between the operation accuracy evaluation index of the stamping sheet material feeding equipment in the historical data and the deviation distance and transport speed abnormality assessment index, and the deviation distance and transport speed abnormality assessment index of the real-time monitoring point are input to obtain their corresponding operation accuracy assessment influencing factors from the mapping set.

[0063] It should be understood that the operation accuracy evaluation index of the stamping sheet material feeding equipment in this embodiment is used to quantitatively evaluate the accuracy of the transportation process of the stamping sheet material feeding equipment.

[0064] This expression takes into account two key factors: deviation distance and transport speed abnormality assessment index, and can provide a comprehensive performance indicator. And because the formula includes specific monitoring points and sheet numbers, it is possible to track which part is performing poorly and make targeted improvements.

[0065] Specifically, a comprehensive analysis is performed to obtain the operational stability evaluation index of the stamping sheet material feeding equipment. The specific analysis process is as follows: deploying a number of vibration data monitoring points, and collecting the vibration intensity of each vibration data monitoring point of each target sheet material at each transportation time monitoring point.

[0066] The working noise intensity of the stamping sheet material feeding equipment is collected, and a comprehensive analysis is performed to obtain the operation stability evaluation index of the stamping sheet material feeding equipment.

[0067] The specific numerical expression of the operation stability evaluation index of the stamping sheet material feeding equipment is:

[0068]

[0069] in, Indicates the operating stability evaluation index of the stamping sheet feeding equipment. It represents the vibration intensity of the zth monitoring point of the yth target sheet at the xth time node. Indicates the set critical vibration intensity, represents the noise intensity of the yth target sheet at the xth time node, represents the set critical noise intensity, Indicates the impact factor of the operation stability assessment corresponding to the set vibration intensity, represents the operation stability assessment influencing factor corresponding to the set noise intensity, x represents the number of each time node, x=1,2,3,...,c, c represents the total number of time nodes, y represents the number of each target sheet, y=1,2,3,...,f, f represents the total number of target sheets, z represents the number of the vibration data monitoring point, z=1,2,3,...,d, d represents the total number of vibration data monitoring points.

[0070] It should be understood that in this embodiment, the vibration sensor and the noise sensor are used to accurately measure the vibration data value and the noise intensity. The greater the vibration intensity, the greater the noise intensity, the lower the operation stability evaluation index, indicating that the stamping sheet material feeding device is more unstable during the sheet material transportation process. The value range of the operation stability evaluation influencing factor corresponding to the vibration intensity, noise intensity and transportation speed abnormality evaluation index is between 0 and 1.

[0071] The operation stability evaluation index of the stamping sheet material feeding equipment is used to quantitatively evaluate the stability of the stamping sheet material feeding equipment during the sheet material transportation process.

[0072] It should be understood that in this embodiment, a mapping set of vibration intensity, noise intensity and corresponding operation stability assessment influencing factors is constructed through the relationship between the operation stability evaluation index of the stamping sheet material feeding equipment in the historical data and the vibration intensity and noise intensity, and the real-time vibration data value and noise intensity are input to obtain their corresponding operation stability assessment influencing factors from the mapping set.

[0073] The expression uses a double-layer summation to first sum the vibration intensities of all monitoring points, and then divides it by the total number of monitoring points to obtain the average vibration intensity. Next, this average value and the noise intensity are transformed together through a hyperbolic tangent function, which ranges from -1 to 1, so that the results can better reflect relative changes rather than absolute values. And because the formula takes into account time series data, it can achieve real-time or near real-time equipment health status monitoring. In addition, by identifying the vibration intensity and noise intensity of each monitoring point of each target sheet, the equipment settings can be adjusted or parts can be replaced in a targeted manner, which helps to improve operating strategies and maintenance plans and reduce the defective rate caused by equipment instability. For example, at the monitoring point near the gearbox of the feeding equipment, if the vibration and noise levels are higher than the normal range, this may be due to gear wear, tooth surface damage or bearing damage. At this time, the operator needs to check the meshing clearance between the gears and adjust it to the appropriate range to reduce shock and vibration.

[0074] Specifically, the environmental data of the stamping sheet material feeding equipment is monitored, and the environmental interference value of the stamping sheet material feeding equipment is obtained through processing. The specific processing process is: the environmental data of the stamping sheet material feeding equipment includes environmental temperature, environmental humidity, and suspended particle concentration.

[0075] According to the environmental data of the stamping sheet material feeding equipment, the environmental interference value of the stamping sheet material feeding equipment is obtained through comprehensive analysis.

[0076]

[0077] in, It indicates the environmental interference value of the stamping sheet feeding equipment, T indicates the ambient temperature, Indicates the reference standard temperature, Indicates the set allowable deviation temperature. Indicates the ambient humidity. Indicates reference standard humidity, Indicates the set allowable deviation humidity, Indicates the concentration of suspended particulate matter. represents the critical suspended particulate matter concentration, Indicates the environmental interference assessment impact factor corresponding to the set temperature, Indicates the environmental interference assessment impact factor corresponding to the set humidity, Indicates the environmental interference assessment impact factor corresponding to the set suspended particulate matter concentration.

[0078] It should be understood that in this embodiment, the ambient temperature, ambient humidity, and suspended particle concentration data are monitored using a thermometer, a hygrometer, and a particle counter. The greater the deviation of the ambient temperature and the ambient humidity from the reference standard value or the greater the concentration of suspended particles, the greater the environmental interference value, which is used to quantify the degree of interference of environmental factors when the stamping sheet feeding equipment is running. The range of values ​​of the environmental interference assessment influencing factors corresponding to temperature, humidity, and suspended particle concentration is between 0 and 1.

[0079] It should be understood that in this embodiment, a mapping set of ambient temperature, ambient humidity, suspended particle concentration and corresponding environmental interference assessment impact factors is constructed through the relationship between the environmental interference value of the stamping sheet feeding equipment in the historical data and the ambient temperature, ambient humidity and suspended particle concentration, and the real-time ambient temperature, ambient humidity and suspended particle concentration are input to obtain their corresponding environmental interference assessment impact factors from the mapping set.

[0080] This expression converts difficult-to-quantify environmental impacts into specific values, allowing staff to understand the actual impact of environmental conditions on equipment performance. By properly controlling environmental factors, not only can equipment efficiency be improved, but unnecessary energy consumption can also be reduced, which can bring more economic benefits in the long run.

[0081] Specifically, a comprehensive analysis is performed to obtain a comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment. The specific analysis process is: the environmental interference value of the stamping sheet material feeding equipment is compared with each comprehensive transmission performance evaluation influencing factor corresponding to each environmental interference value interval stored in the stamping sheet material feeding equipment database, wherein each comprehensive transmission performance evaluation influencing factor includes a comprehensive transmission performance evaluation influencing factor corresponding to an operation accuracy evaluation index and a comprehensive transmission performance evaluation influencing factor corresponding to an operation stability evaluation index.

[0082] According to the operation accuracy evaluation index and operation stability evaluation index of the stamping sheet material feeding equipment, a comprehensive analysis is performed to obtain the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment.

[0083]

[0084] in, Indicates the comprehensive transmission performance evaluation value of the stamping sheet feeding equipment. Indicates the operating accuracy evaluation index of the stamping sheet feeding equipment. Indicates the operating stability evaluation index of the stamping sheet feeding equipment. It represents the comprehensive transmission performance evaluation impact factor corresponding to the operation accuracy evaluation index, It represents the comprehensive transmission performance evaluation influencing factor corresponding to the operation stability evaluation index.

[0085] like Figure 2 As shown, =0.3, =0.5. =0.6, the functional relationship between the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment and the operation accuracy evaluation index of the stamping sheet material feeding equipment is shown in curve a; when =1, the functional relationship between the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment and the operation accuracy evaluation index of the stamping sheet material feeding equipment is shown in curve b; when =1.6, the functional relationship between the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment and the operation accuracy evaluation index of the stamping sheet material feeding equipment is shown in curve c. The comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment is jointly determined by the operation accuracy evaluation index and the operation stability evaluation index. The larger the operation accuracy evaluation index or the operation stability evaluation index, the larger the comprehensive transmission performance evaluation value and the better the comprehensive performance.

[0086] It should be understood that in this embodiment, by using a hyperbolic sine function to perform nonlinear transformation on the comprehensive performance evaluation result, the phenomenon that the comprehensive performance of the equipment accelerates with the improvement of accuracy and stability can be more accurately reflected. The coefficients of the operation stability evaluation index and the accuracy evaluation index are used to quantify their influence on the comprehensive performance, and the value range is between 0 and 1. These two factors can be adjusted by the environmental interference value to make the evaluation more suitable for the experimental environment.

[0087] It should be understood that in this embodiment, a mapping set of the operation accuracy evaluation index, the operation stability evaluation index and the corresponding comprehensive transmission performance evaluation influencing factors is constructed through the relationship between the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment in the historical data and the operation accuracy evaluation index and the operation stability evaluation index, and the real-time operation accuracy evaluation index and the operation stability evaluation index are input to obtain their corresponding comprehensive transmission performance evaluation influencing factors from the mapping set.

[0088] The comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment is used to quantify the comprehensive performance of the stamping sheet material feeding equipment during the transmission process.

[0089] This expression provides a standardized method to evaluate the performance differences between different devices, making it easier to compare and select the optimal equipment. Manufacturers and operators can better understand the comprehensive transmission performance of the equipment and make more reasonable decisions based on it. Whether it is daily monitoring, maintenance planning or equipment selection, it can be supported by strong data.

[0090] Specifically, a performance evaluation is performed based on the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment, and the evaluation results are obtained and fed back. The specific evaluation process is: the comprehensive transmission performance evaluation threshold is extracted from the stamping sheet material feeding equipment database, and the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment is compared with the comprehensive transmission performance evaluation threshold. If the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment is greater than or equal to the comprehensive transmission performance evaluation threshold, the comprehensive transmission performance of the stamping sheet material feeding equipment is evaluated as qualified; if the comprehensive transmission performance evaluation value of the stamping sheet material feeding equipment is less than the comprehensive transmission performance evaluation threshold, the comprehensive transmission performance of the stamping sheet material feeding equipment is evaluated as unqualified, and the unqualified evaluation result is fed back to relevant personnel.

[0091] The stamping sheet material feeding equipment database is used to store data related to the stamping sheet material feeding equipment, including the comprehensive transmission performance evaluation influencing factor corresponding to the operation accuracy evaluation index of the stamping sheet material feeding equipment, the comprehensive transmission performance evaluation influencing factor corresponding to the operation stability evaluation index, the environmental interference evaluation influencing factor corresponding to the ambient temperature, the environmental interference evaluation influencing factor corresponding to the ambient humidity, the environmental interference evaluation influencing factor corresponding to the suspended particulate matter concentration, the comprehensive transmission performance evaluation threshold and other reference indicators.

[0092] The data in the stamping sheet feeding equipment database can be obtained by collecting laboratory data or indicator data provided by the equipment manufacturer.

[0093] In a specific embodiment, the present invention improves the reliability and scientificity of feedback by evaluating the comprehensive performance of the stamping sheet feeding equipment. Through effective data collection and processing, starting from multiple test dimensions, it significantly improves the accuracy of the test results, avoids data waste, and enhances the overall value of the data.
