[0067] If the detection performance value GC of the detection point is greater than the performance value threshold, the detection point is marked as an abnormal detection point;

[0068] If the detection performance value GC of the detection point is less than or equal to the performance value threshold, the detection point is marked as a normal detection point;

[0072] It should be noted that the purpose of the performance abnormal value YX is to analyze the number of abnormal detection points on the film-laminated metal composite plate and the degree of abnormality of the detection points, and then evaluate and judge the overall quality of the film-laminated metal composite plate;

[0073] Step 2: Obtaining the performance abnormality value of the film-laminated metal composite plate, analyzing the performance abnormality value of the film-laminated metal composite plate, judging whether the film-laminated metal composite plate is qualified, and marking the composite plate judged to be unqualified as an unqualified composite plate;

[0077] If the performance abnormality value of the laminated metal composite panel is less than or equal to the performance abnormality threshold, the composite panel is judged to be qualified;

[0078] The technical solution of the embodiment of the present invention is: obtaining performance data of the film-laminated metal composite plate during the quality inspection process, wherein the performance data includes the gloss value of the inspected composite plate and the color difference value of the inspected composite plate based on the standard composite plate, obtaining performance abnormality values ​​by performing data analysis on the performance data, obtaining the performance abnormality values ​​of the film-laminated metal composite plate, and determining whether the film-laminated metal composite plate is qualified by analyzing the performance abnormality values ​​of the film-laminated metal composite plate, thereby realizing efficient and accurate quality inspection of the film-laminated metal composite plate.

[0079] Example 3

[0080] like Figure 1 As shown, based on Example 2, a method for manufacturing a film-laminated metal composite plate according to an embodiment of the present invention includes:

[0081] Step 3: based on the marked unqualified composite plate, obtain abnormal analysis data of the unqualified composite plate, wherein the abnormal analysis data includes the thickness value of the composite plate at each detection point, and obtain the abnormal analysis value by performing data processing on the abnormal analysis data;

[0082] Specifically, the thickness value of the composite plate at each test point on the unqualified composite plate is obtained, the thickness value of the composite plate is subjected to difference processing with the standard thickness value and the absolute value is taken to obtain the thickness deviation value;

[0083] Compare the obtained thickness deviation value with the thickness deviation threshold:

[0084] If the thickness deviation value of the detection point is greater than the thickness deviation threshold, it means that the thickness deviation of the detection point is too large, and a deviation signal is sent;

[0085] If the thickness deviation value of the detection point is less than or equal to the thickness deviation threshold, it means that the thickness deviation of the detection point is small;

[0086] The number of detection points on the laminated metal composite plate that send deviation signals is obtained, and the number of detection points that send deviation signals is ratioed to the total number of detection points on the composite plate to obtain a thickness deviation ratio, which is marked as KLC;

[0089] It should be noted that the meaning of the abnormal analysis value SK is: by analyzing the number of detection points with thickness deviation in the abnormal detection points and the unevenness of the thickness of the metal composite plate, the abnormal level of the unqualified composite plate is further evaluated, which is convenient for the subsequent classification and processing of the unqualified composite plate;

[0090] Step 4: Based on the obtained abnormal analysis values, the unqualified composite plates are classified into composite plates with abnormal thickness and composite plates with abnormal performance, the composite plates with abnormal thickness are recycled, and the composite plates with abnormal performance are repaired;

[0091] Get the abnormal analysis value of the film-laminated metal composite plate and compare the abnormal analysis value with the abnormal analysis threshold:

[0092] If the abnormal analysis value is greater than the abnormal analysis threshold, the unqualified composite plate is judged to be a composite plate with abnormal thickness, and a signal to be recycled is sent;

[0093] If the abnormal analysis value is less than or equal to the abnormal analysis threshold, the unqualified composite board is judged to be an abnormal composite board, and a signal to be repaired is sent;

[0094] It should be noted that the composite panels that are unqualified due to uneven thickness of the laminated metal composite panels cannot be simply repaired to meet the manufacturing standard requirements, so they can only be recycled for processing;

[0095] If a signal to be recycled is received, the unqualified composite board is recycled; if a signal to be repaired is received, the unqualified composite board is repaired, further realizing efficient and high-quality manufacturing of laminated metal composite boards;

[0096] The technical solution of the embodiment of the present invention is: based on the marked unqualified composite plates, abnormal analysis data of the unqualified composite plates are obtained, wherein the abnormal analysis data include the thickness values ​​of the composite plates at each detection point, and the abnormal analysis values ​​are obtained by processing the abnormal analysis data; based on the obtained abnormal analysis values, the unqualified composite plates are classified into composite plates with abnormal thickness and composite plates with abnormal performance, the composite plates with abnormal thickness are recycled and discarded, and the composite plates with abnormal performance are repaired; further realizing efficient and high-quality manufacturing of laminated metal composite plates.
