TECHNICAL FIELD
[0001] The present application belongs to the technical field of impact ram production detection, and particularly relates to an impact ram multi-station online detection system and a detection method. BACKGROUND
[0002] The existing impact ram production is mostly manually or mechanically assembled in multiple stations. Due to the negligence of the previous operation or the quality problem of the parts, unqualified workpieces are easily flowed into the next operation, resulting in waste of production resources and reduction of production efficiency.
[0003] To solve this problem, some production lines have set up basic detection devices such as CCD vision detection in a single station, but the technical defects of the quality problem tracing link have become the key bottleneck restricting the production efficiency and quality control level. After the existing technology finds the quality problem, it mostly relies on manual investigation of the previous operation records or simply speculates the root cause through the sequence correlation of the operation, and the impact ram assembly quality is affected by multiple stations and multiple parameters. The manual tracing not only has low positioning accuracy, but also has a root positioning error of 2-3 stations, and is easy to misjudge the root station, miss the related operation, and other problems, resulting in repeated occurrence of similar quality problems. At the same time, the detection data of each station is independent of each other, and when the terminal detection finds unqualified workpieces, it cannot trace the transmission process from the root station to the current station, and it is difficult to accurately identify the key nodes of abnormal transmission, so that the improvement measures lack pertinence. In addition, manual tracing needs to call multiple historical records of stations, compare operation parameters, and the average tracing time is 5-10 minutes, during which the production line needs to be suspended or run at low speed, causing production stagnation loss. Especially in the flexible production line mixed production scene of multiple models, the process parameters and station adaptation requirements of different models of impact rams are different, which further increases the complexity of manual tracing and reduces the tracing efficiency. More importantly, the existing technology is only used to solve the processing of a single unqualified workpiece, and for the same source quality problem that occurs frequently, it cannot optimize the detection threshold and adjust the detection focus through the tracing result, resulting in a "two-piece" between tracing and detection, and it is difficult to fundamentally improve the quality control level.

[0026] Impact rammer multi-station online detection method The method is realized based on the above system, with core reinforcement of traceability related steps, specifically including the following steps: Step 1: single-station basic detection and data synchronization The CCD vision sensor of each station collects x / y / z axis deviation data (Δx, Δy, Δz) of part assembly, the device sensor collects assembly pressure (F 工 ), operation speed (v 工 ), running vibration (a 工 ) and other parameters, and the data preprocessing module transmits the "parameter data + station number + timestamp" to the multi-station traceability linkage core module and data storage module after noise reduction by mean filtering (window size is 5). At the same time, the system automatically records the unique identification code of each workpiece (including model information, online time, and serial number of workstations), realizing one-to-one correspondence between workpiece and multi-station data.
[0027] Step 2: dynamic disturbance compensation The dynamic disturbance compensation module calls the synchronous detection data of the previous adjacent station (previous station force sensor data F 前序 , vibration sensor data a 前序 ), combined with the distance between the current station and the previous station The force and vibration original data of the current station are corrected by the following formula: wherein, is an interference compensation factor, with a value range of 0-0.8; is a distance reference value, fixed at 2 m; , is the original force and vibration acceleration data collected by the current station sensor; , is the corrected effective data.
[0028] Step 3: Multi-dimensional coupling evaluation The multi-dimensional re-inspection unit of the key process receives the effective data after dynamic interference compensation, and calculates the comprehensive quality evaluation value Q through the multi-physical field coupling detection model, as follows: wherein, is an actual assembly space deviation value; is the maximum assembly deviation threshold value allowed by the impact ram of this model, called from the flexible production parameter database; , , is the weight coefficient of each dimension parameter, satisfying + + =1, the initial value is determined by the analytic hierarchy process ( =0.5, =0.3, =0.2), and is dynamically adjusted by an adaptive algorithm subsequently; is the standard assembly contact force reference value of this process, is the standard vibration acceleration reference value of this process, both called from the flexible production parameter database ( obtained by statistical analysis of more than 1000 sets of qualified product data, for the same reason). When ≥ (an adaptive threshold value), the traceability process is triggered; When , only the data is stored, without starting the traceability. Step 4: Multi-station quantitative traceability The multi-station traceability linkage core module receives the Process correlation degree ), accurate traceability is realized through the following quantitative model. It includes: 4.1 Root attribution coefficient calculation Formula symbol definition: is the root attribution coefficient, the value range is 0-n (n is the number of previous correlation stations, the default n=3, which can be adjusted according to the length of the production line), The closer the value is to an integer , the higher the confidence that the station is the root station; =0 is the current station, =1-n is the previous 1-n station; is the comprehensive quality evaluation value of the workpiece of the th station (Q =0 is the current abnormal workpiece value, ≥1 is the detection value of the same workpiece corresponding to the previous station), is the adaptive decision threshold of the current process.
[0029] is the station weight coefficient, which is determined by the "distance attenuation factor" and "process correlation degree": is the distance (unit: m) between the th station and the current station, =0.8 is the distance attenuation coefficient (calibrated by 1000 groups of traceability cases); is the process correlation degree between the th station and the current station (such as the =0.95 between the previous core component assembly station and the terminal detection station, and the =0.3-0.6 of auxiliary stations, which is called from the flexible production parameter database). is the time attenuation factor, is the detection time of the current station, is the detection time of the th station, =0.5 is the time attenuation coefficient, which is used to correct the influence of the difference in detection time of different stations on traceability (the closer the detection time, the higher the weight). Root station determination rule: ∈[ -0.2, +0.2] =0,1,...,n): determine the first station as the unique root station; ∈( +0.2, +1-0.2): determine the first station and the first +1 station as the joint root station (the anomaly is caused by the joint influence of the two stations), and allocate the influence weight according to the ratio of . When all corresponding ≤0, it is determined that the current station has a sudden anomaly (such as a transient failure of the device or a batch defect of the part), and the traceability result is marked as "current station independent anomaly".
[0030] 4.2 Abnormal Conduction Path Tracing Trace the conduction process of the deviation from the root station to the current station through the abnormal conduction intensity formula: Formula symbol definition: is the abnormal conduction intensity from the first station to the first +1 station, S≥0.3 is determined as "strong conduction" (the deviation is significantly amplified in this path), 0.1≤S<0.3 is "weak conduction", and S<0.1 is "no conduction"; is the core parameter deviation value (such as assembly space deviation , force parameter deviation ) of the first station, is the corresponding parameter deviation value of the first +1 station; is the conduction attenuation coefficient, is the distance between the first station and the first +1 station, =0.3 is the attenuation coefficient (based on deviation conduction test calibration of different station distances); is the standard deviation threshold of the parameter (called from the flexible production parameter database). Path tracing output: the system automatically generates an abnormal conduction path diagram, labels the root station, key conduction stations (path nodes with S≥0.3), deviation amplification multiple, and parameter deviation contribution of each station, and intuitively presents the complete process of the anomaly from generation to manifestation.
[0031] Step 5: Hierarchical linkage processing The process linkage control module executes targeted processing strategies based on the traceability results (root cause station, joint root cause station, transmission path), replacing the traditional unified processing method: Level 1 anomaly (0.8≤ < If the source is traced back to a slight deviation in a single workstation, calculate the compensation parameters. ( (To maximize the transmission intensity), a compensation command is sent to the next workstation, and a deviation warning is pushed to the source workstation at the same time; Level 2 abnormality ( ≤ <1.2): If it is a single source workstation, suspend operations at that workstation and send out a source tracing report (including the source attribution coefficient). (Abnormal parameters, transmission paths), guide staff to make targeted rectifications; if it is a joint root cause workstation, suspend related workstations, analyze the collaborative impact mechanism, and formulate a comprehensive rectification plan; Level 3 abnormality ( ≥1.2): Lock the non-conforming workpiece and trigger the scrapping process. At the same time, based on the source tracing results, analyze the key nodes of abnormal transmission and strengthen the detection parameters of the workstation at that node (such as increasing the detection frequency and reducing the detection threshold). Step 6: Source tracing result-driven detection optimization The adaptive threshold optimization module incorporates source data into the threshold iteration model, achieving a closed loop of "source tracing-optimization": in, For the first The new detection threshold after the next iteration The threshold for pre-detection. The learning rate is controlled by dynamically adjusting the threshold value: this is useful when production fluctuates greatly (e.g., during line changes or batch replacements of parts). =0.03-0.05; Production is stable (no level 2 or higher abnormalities for 1 consecutive hour) =0.01-0.02, the system automatically adjusts based on production stability. The number of data samples for threshold iteration. Let be the source tracing weight coefficient, if the th If the traceability result for a workpiece is "high-frequency root cause station anomaly" (the traceability frequency for this station is ≥3 times in the past hour), then... 1.5; If it is "abnormal fixed conduction path", then =1.2; if it is an "occasional anomaly", then = 0.8. Through this formula, the detection threshold is tilted towards the parameter direction associated with the high-frequency problem, and the detection sensitivity for root cause workstation abnormalities is enhanced. Step 7: Full-process data storage and traceability The data storage module, as the "data hub" of the system, stores the traceability-related data of the full-process impact ram assembly detection in real time and completely based on an industrial-grade distributed database architecture, builds a full-link data archive of "data collection-traceability analysis-linkage processing-optimization iteration", and completely solves the pain points of "fragmentation of traceability data, inefficient query, and inability to support production optimization in reverse" in the prior art.
[0032] The stored data not only includes core traceability results, but also associates basic data of each preceding link and optimization data of each subsequent link to form a complete data chain: Basic detection raw data: x / y / z axis deviation raw values (Δx, Δy, Δz) collected by CCD vision sensors at each workstation, raw force values of force sensors , raw acceleration of vibration sensors , and denoised data after data preprocessing, corrected data after dynamic interference compensation , , with each piece of data bound to a workstation number, a collection timestamp, and a unique workpiece identification code; Multi-dimensional evaluation data: comprehensive quality evaluation values of key processes , and historical iteration records of adaptive decision thresholds ; Core traceability data: complete calculation process of root cause attribution coefficients , root cause workstation determination results, abnormality transmission intensity S, transmission attenuation coefficient k, deviation amplification factor, and structured data of abnormality transmission path diagram (node workstation, transmission sequence, key transmission node marker); Linkage processing data: hierarchical linkage processing instructions, staff rectification operation logs (rectification time, rectification measures, review results), and unqualified workpiece disposal records (scrap identification, unique identification code, disposal time); Optimization iteration data: assignment basis of traceability weight coefficients (abnormal type, high-frequency abnormality frequency statistics, and transmission path fixedness determination results), and threshold optimization logs.
[0033] The system supports query requirements in different scenarios such as production management, quality analysis, and problem troubleshooting, provides multiple core query dimensions, and the query results can be exported as structured reports (Excel / CSV format).
[0034] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them.
