[0042] Please refer to Figure 4 , secondly, a car door interior panel size detection system is used for the car door interior panel size detection tool in the first aspect, comprising a database 20, a collection module 21, a query module 22 and a judgment module 23, the database 20 is connected with the query module 22, the query module 22 and the collection module 21 are respectively connected with the judgment module 23.

[0043] The database 20 is used for storing the standard size data of different types of interior panels.

[0044] The collection module 21 is used for obtaining the size data of the interior panel to be detected.

[0045] The query module 22 is configured to query the standard size data of the detected interior trim panel in the database 20.

[0046] The judgment module 23 is configured to judge the size data of the detected interior trim panel based on the queried standard size data and output a detection report.

[0047] In the embodiment, the database 20 is designed as a relational database 20 and contains a plurality of data tables. The main tables include an "interior trim panel model table", a "size specification table", and a "detection record table". The "interior trim panel model table" stores the model information of the interior trim panel, such as model ID, model name, and applicable vehicle model. The "size specification table" is associated with the model ID and records the standard values of each size parameter in detail, including length, width, height, thickness, hole diameter, and margin. The "detection record table" is used to store the detailed data of each detection, including detection time, detection personnel, detection equipment, interior trim panel model, actual measurement values of each size parameter, and judgment results. The database 20 has a regular update mechanism, receives new interior trim panel model and size specification data from the internal network of the automobile manufacturer every week, and automatically synchronizes to the database 20. At the same time, manual update function is supported to update the database 20 through offline data import mode in emergency or network failure.

[0048] The acquisition module 21 is configured to acquire the size data of the interior trim panel. During the detection process, the acquisition module 21 starts to work by triggering a start signal. The mechanical arm drives the laser range finder and optical sensor to scan according to the preset measurement path, and real-time acquires the size data of each measurement point. The acquired data is transmitted to the acquisition module 21 through the data line, and is subjected to preliminary filtering and calibration processing to remove noise and abnormal values, so as to ensure the accuracy and reliability of the data.

[0049] The query module 22 adopts an algorithm based on keyword matching and association query. When receiving the model information of the detected interior trim panel, first, the keywords of the model are extracted, and then a fuzzy matching query is performed in the "interior trim panel model table" of the database 20 to quickly locate the record closest to the current detected interior trim panel model. Subsequently, the corresponding specification size data of the interior trim panel of this model is retrieved in the "size specification table" according to the association relationship. During the query process, if the model information is incomplete or there is no matching record in the database 20, the query module 22 has a corresponding exception handling mechanism. For the case of incomplete model information, the system will prompt the user for supplementary input, and according to the supplemented information, the query is performed again; if there is no matching record in the database 20, a default general interior trim panel size specification template is returned, and it is marked as "no matching model" in the detection report, reminding the detection personnel to pay special attention to the detection result and manually review. If the actual measured value is within the tolerance range of the specification size, it is determined that the size parameter is qualified; otherwise, it is determined to be unqualified. According to the judgment results of each size parameter, the overall detection result of the interior trim panel is divided into "qualified", "slightly unqualified" and "serious unqualified" three categories. Among them, all size parameters are qualified, which is "qualified"; there are a small number of non-key size parameters slightly exceeding the tolerance range, which is "slightly unqualified"; and the key size parameter is unqualified or multiple size parameters seriously exceed the tolerance range, which is "serious unqualified". The detection report is generated in a standardized format, including the model of the interior trim panel, the detection time, the detection equipment information, the actual measured value of each size parameter, the specification size value, the tolerance range and the judgment result, etc. The report is divided into electronic and paper versions. The electronic report is stored in the "detection record table" of the database 20, which is convenient for subsequent query and statistical analysis; the paper version of the report can be output through the printer for on-site detection personnel and quality management personnel to check and archive.

[0050] The judgment module 23 judges the collected interior trim panel size data according to the queried specification size data and in combination with the preset tolerance range. The tolerance range is set with reference to the production process standards and quality control requirements of the automobile manufacturer. For key size parameters, such as the size related to the closing of the door, the tolerance range is set to ±0.1 mm; for non-key size parameters, such as the decorative edge size of the interior trim panel, the tolerance range can be widened to ±0.5 mm. The judgment logic adopts the way of item-by-item comparison to compare the actual measurement value with the specification size data one by one. If the actual measurement value is within the tolerance range of the specification size, it is determined that the size parameter is qualified; otherwise, it is determined to be unqualified. According to the judgment results of each size parameter, the overall detection result of the interior trim panel is divided into three categories: “qualified”, “slightly unqualified” and “seriously unqualified”. All size parameters are qualified, which is “qualified”; there are a small number of non-key size parameters slightly exceeding the tolerance range, which is “slightly unqualified”; and the key size parameter is unqualified or a plurality of size parameters seriously exceed the tolerance range, which is “seriously unqualified”. The detection report is generated in a standardized format, including the model of the interior trim panel, the detection time, the detection equipment information, the actual measurement value of each size parameter, the specification size value, the tolerance range and the judgment result, etc. The report is divided into electronic and paper versions. The electronic version of the report is stored in the “detection record table” of the database, which is convenient for subsequent query and statistical analysis; the paper version of the report can be output through the printer for on-site detection personnel and quality management personnel to check and archive. At the same time, the system supports sending the detection report in PDF format to the designated recipient through email, realizing the rapid sharing and transmission of the detection result.

[0051] Please refer to Figure 5 In a third aspect, a method for detecting the size of an automobile door interior trim panel is provided. The method can be used in the system for detecting the size of an automobile door interior trim panel of the second aspect. The method comprises the following steps:

[0052] S1 acquiring size data of the interior trim panel to be detected;

[0053] Specifically, before detection, it is ensured that the surface of the interior trim panel to be detected is clean, free of stains and scratches, so as to avoid affecting the accuracy of size measurement due to the surface condition. The interior trim panel is placed on the detection device body 2 and fixed, and the detection device body 2 is started to detect the interior trim panel. The acquisition module 21 acquires the linear size of the interior trim panel, such as length, width and height. The acquired size data is transmitted in real time to the data processing unit through the data line. In the data processing unit, the data is first filtered to remove abnormal values caused by equipment noise, environmental interference and other factors; then, calibration is performed to correct the measurement value according to the reference data of the calibration block, so as to ensure the accuracy and reliability of the data.

[0054] S2 querying the specification size data of the current detection interior trim panel in the database 20;

[0055] Specifically, the query module 22 receives the processed model information, performs a fuzzy matching query in the "interior panel model table" of the database 20, and quickly locates the record closest to the current detected interior panel model. Then, the corresponding specification size data of the interior panel of this model is retrieved in the "size specification table" according to the association relationship, including the specification values and tolerance ranges of each size parameter. The queried specification size data is returned to the judgment module 23, and if multiple matching records appear during the query process, the system will select the most accurate one as the judgment basis according to the record update time and relevance. At the same time, the system will record the log information of the query operation, including the query time, query user, query condition, etc., for subsequent audit and traceability.

[0056] S3 judges the size data of the detected interior panel based on the queried specification size data and outputs a detection report.

[0057] Specifically, the judgment module 23 compares the collected interior panel size data with the queried specification size data item by item. For each size parameter, it is judged according to the preset tolerance range. If the actual measurement value is within the tolerance range of the specification size, the size parameter is determined to be qualified; otherwise, it is determined to be unqualified. During the judgment process, the system will record the judgment results of each size parameter in detail, including whether it is qualified, the deviation value, etc. According to the judgment results of each size parameter, the overall detection result of the interior panel is divided into three categories: "qualified", "slightly unqualified" and "seriously unqualified". For the "qualified" interior panel, the system will automatically generate a detection report containing the detailed information of the interior panel, the detection result, etc., and store the electronic version of the report in the database 20. For the "slightly unqualified" interior panel, the system will mark the unqualified size parameter in the detection report and suggest manual review and repair. For the "seriously unqualified" interior panel, the system will issue an alarm to remind the detection personnel to handle it immediately, and feedback the unqualified information to the production department for timely adjustment of production process. The detection report is generated in a standardized format, containing the model of the interior panel, the detection time, the detection equipment information, the actual measurement value of each size parameter, the specification size value, the tolerance range and the judgment result, etc. The report is in two forms: electronic and paper. The electronic report is stored in the "detection record table" of the database 20, facilitating subsequent query and statistical analysis; the paper report can be output through a printer for on-site detection personnel and quality management personnel to check and archive. At the same time, the system supports sending the detection report in PDF format to the designated recipients through email, realizing the rapid sharing and transmission of detection results.

[0058] The above only discloses a preferred embodiment of the size detection tool for the automobile door interior panel, and of course cannot limit the scope of the utility model, and those skilled in the art can understand that all or part of the processes of the above embodiment can be implemented, and equivalent changes made according to the utility model claim still belong to the range covered by the utility model.
