The number of bends the wire harness can withstand before insulation cracking, wire breakage, and other failures occur is recorded. The number of bends is recorded as the bending life value (Si). At the same time, the wiring harness is fixed on a vibration test bench, and a vibration environment is simulated according to the vibration frequency, amplitude, and vibration time in the actual use environment. After the vibration test, the various components of the wiring harness are checked for looseness, displacement, wear, or damage.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a diagram of the steps and methods of the present invention; Figure 2 This is a block diagram of the system principle of the present invention. DETAILED DESCRIPTION

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] For example 1, please refer to Figure 1 The present application provides a method for detecting the processing quality of a wire harness, which specifically includes the following steps: Step S001: obtain all wiring harnesses, select multiple groups of target wiring harnesses by sampling, and simultaneously obtain wiring harness information corresponding to the target wiring harnesses, wherein the wiring harness information includes appearance information, electrical performance information, and mechanical performance information.

[0017] All wiring harnesses are obtained and sorted by batch. Multiple groups of wiring harnesses are sampled from the same batch and labeled as target harnesses, with i = 1, 2, ..., j, where j represents the number of target harnesses. For example, an automotive wiring harness manufacturer, after producing harnesses, first categorizes all harnesses by production date and process batch. For example, the first batch of harnesses produced on the morning of October 1, 2024, is a batch. Five wiring harnesses are randomly sampled from this batch as target harnesses, labeled 1, 2, 3, 4, and 5 (i.e., j = 5). The appearance, electrical performance, and mechanical performance information of the target harnesses are then obtained. Professional instruments are used to inspect the appearance of the wires for damage and the uniformity of the insulation thickness. Electrical performance information such as conductivity and insulation resistance is tested using equipment such as continuity testers and withstand voltage testers. Mechanical performance information such as tensile strength and bending fatigue life is tested using tensile testing machines and bend testing equipment.

[0018] Step S002 : Based on the appearance information of the target wiring harness, by comprehensively scoring the appearance information and calculating the appearance value of the target display, the appearance values ​​of all wiring harnesses are further calculated.

[0019] Obtain the appearance information corresponding to the target wiring harness i, and then classify the target wiring harness i according to the integrity of the wiring harness in the appearance information to obtain a complete wiring harness and a defective wiring harness, and record them as a respectively, and a=1, 2, ..., a1, b=1, 2, ..., b1, where a1+b1=j, and obtain the defective wiring harness b at the same time, then obtain the defect situation corresponding to the defective wiring harness b, and determine the defect level according to the defect situation, and assign a defect value according to the defect level and record it as Fb. For example, a defective wiring harness b was found in an electronic equipment wiring harness processing plant. Upon inspection, the wiring harness had multiple minor scratches on the wire insulation layer and a loose connection of a terminal. According to the defect level classification standard established by the factory, this situation was judged to be a medium defect level. According to the assignment rule, the value corresponding to the medium defect level is 3, so the defect value Fb of the defective wiring harness b is determined to be 3. If another defective wiring harness has serious wire breakage and multiple insulation layer damage, it may be judged as a serious defect level, and the corresponding defect value Fb may be 5; Then calculate the defect mean corresponding to all defective harnesses b and record it as Fp. The defect mean here is obtained by calculating the sum of the defect values ​​of all defective harnesses and then calculating the mean of the sum of the defect values. At the same time, substitute the obtained defect mean Fp into the formula Calculate the appearance value Q corresponding to all target harnesses, and is the preset proportional coefficient, and then according to the formula The appearance value Q1 corresponding to all wiring harnesses is calculated, and the appearance value Q1 calculated here is an estimated value. The appearance value of all wiring harnesses is estimated by the appearance value obtained from the sample survey, and Z is the number of all wiring harnesses, and is the preset proportional coefficient; Step S003 , based on the electrical performance information of the target wiring harness, and by analyzing the conductivity and insulation of the target wiring harness, the corresponding resistance value and insulation value are calculated, and then the electrical performance values ​​of all wiring harnesses are calculated based on the resistance value and insulation value.

[0020] Get the target harness i, and at the same time get the contact resistance of the connection point corresponding to the target harness i, and judge the contact resistance. Rating information is obtained based on different contact resistances, and then different values ​​are assigned to the rating information to obtain the resistance value Ri. For example, in the quality inspection link of a certain communication equipment harness, for the target harness 3, a micro-ohmmeter is used to measure the contact resistance of its connection point. If the contact resistance of a certain connection point is measured to be 0.02 ohms, according to the set evaluation criteria, the contact resistance is less than 0.05 ohms, which is an excellent grade. The excellent grade is assigned a value of 1, then the resistance value corresponding to this connection point is R3 That is 1. For example, if the contact resistance of a connection point of another target harness 7 is 0.1 ohms, and the contact resistance between 0.05 ohms and 0.15 ohms is judged to be a good grade, and the good grade is assigned a value of 2, then the resistance value R7 of the connection point is 2. At the same time, the insulation resistance value corresponding to the target harness i is obtained, and the insulation resistance value is graded to obtain the rating information. Then, the rating information is assigned different values ​​to obtain the insulation value recorded as R1i. For example, in the detection process of the power transmission harness, for the target harness 5, the insulation resistance value measured by the insulation resistance tester is 500 megohms. If the insulation resistance value is greater than 100 megohms as the "excellent" grade, and the "excellent" grade is assigned a value of 1, then the insulation value R1i corresponding to the target harness 5 is 1. For another example, the insulation resistance value of the target harness 8 is 30 megohms. If the insulation resistance value is specified to be between 20-100 megohms as the "good" grade, and the "good" grade is assigned a value of 2, then the insulation value R1i of the target harness 8 is 2; Substitute the obtained resistance value Ri and insulation value R1i into the formula The electrical performance value Lz of the target harness i is calculated, where is a preset proportional coefficient, the specific value is set by the operator, and then the electrical performance value of all wiring harnesses is calculated based on the obtained electrical performance value Lz, which is recorded as L, and the calculation formula is , and Z is the number of all bundles, where It is a preset proportional coefficient, and the specific value is set by the operator; Step S004 , based on the mechanical performance information of the target wiring harness and by analyzing the maximum tension, bending life and vibration conditions corresponding to the target wiring harness, the mechanical performance value of the target wiring harness is comprehensively calculated, and the mechanical performance values ​​of all wiring harnesses are calculated simultaneously.

[0021] The mechanical properties of target wiring harness i are obtained, along with the corresponding maximum tensile force. This maximum tensile force is measured using a tensile testing machine. During testing, the tensile force is gradually increased until the connector separates from the conductor or a specified tensile force is reached. The tensile force at this point is recorded, and a rating is generated based on the maximum tensile force to obtain rating information. Based on this rating information, the maximum tensile force of target wiring harness i is assigned a tensile force value, Ki. For example, during the quality inspection process at an automotive wiring harness manufacturer, target wiring harness 10 is tested using a tensile testing machine. During the test, the tensile force is gradually increased from 0. When the tensile force reaches 80 Newtons, the connector separates from the conductor. If the manufacturer specifies a maximum tensile force greater than 100 Newtons as "excellent," assigned a value of 1; 50-100 Newtons as "good," assigned a value of 2; and less than 50 Newtons as "unacceptable," assigned a value of 3, then target wiring harness 10, with a maximum tensile force of 80 Newtons, is rated "good," and its corresponding tensile force value is 2.

[0022] The wire harness is then fixed on a bending test device and repeatedly bent at a certain bend radius, bend angle, and bend frequency. The number of bends the wire harness can withstand before insulation cracking, wire breakage, and other failures occur is recorded. The number of bends is recorded as the bending life value (Si). At the same time, the wiring harness is fixed on the vibration test bench, and the vibration environment is simulated according to the vibration frequency, amplitude and vibration time in the actual use environment of the product. After the vibration test, the various components of the wiring harness are checked for looseness, displacement, wear or damage. The wiring harness is rated based on the inspection results to obtain rating information, and the vibration value Gi is assigned based on the rating information; For example, during the wire harness quality inspection process, for target wire harness 15, the bending test was performed with a bend radius of 5 cm, a bend angle of 90 degrees, and a bending frequency of 30 times per minute. After 10,000 bends, the insulation layer of the wire harness showed slight cracking, resulting in a bending life value S15 of 10,000. During the vibration test, the vibration frequency (e.g., 20-50 Hz), amplitude (e.g., 0.5-2 mm), and duration (e.g., 2 hours) of an aircraft flight were simulated. After the vibration test, a slightly loose terminal was found in the wire harness. According to the rating criteria, this condition is rated "mildly abnormal." If the "mildly abnormal" rating is assigned a value of 4, the vibration value G15 for target wire harness 15 is 4.

[0023] Then substitute the tensile force value Ki, bending life value Si and vibration value Gi into the formula The mechanical performance value Pz corresponding to the target harness is calculated, and the mechanical performance value of all harnesses is calculated based on the mechanical performance value Pz of the target harness, which is recorded as P1. The specific calculation formula is: , and Z is the number of all bundles, where is the preset scale factor.

[0024] Step S005 , calculating the quality values ​​corresponding to all wiring harnesses according to the obtained appearance values, electrical performance values, and mechanical performance values, and performing quality inspection according to the quality values, and generating quality inspection information.

[0025] Substitute the obtained appearance value Q1, electrical performance value L1 and mechanical performance value P1 into the formula The quality value Y corresponding to all wire harnesses is calculated and matched with the quality interval. The quality interval here is obtained based on historical data analysis. The quality interval is generated based on different quality values, and the corresponding quality level is matched, and quality detection information is generated at the same time.

[0026] For example, a manufacturer of electronic equipment wiring harnesses tests the wiring harness's appearance (e.g., wire scratches, insulation integrity, etc.) to obtain an appearance value (Q1), tests electrical properties (e.g., conductivity, insulation resistance, etc.) to obtain an electrical performance value (L1), and tests mechanical properties (e.g., tensile strength, flex life, etc.) to obtain a mechanical performance value (P1). Assume the quality assessment formula is Y = 0.3Q1 + 0.4L1 + 0.3P1 (this is just an example formula; the weighting can be adjusted based on the importance of each performance factor). If a wiring harness has Q1 = 80 (out of 100), L1 = 90, and P1 = 70, the calculation yields Y = 0.3 × 80 + 0.4 × 90 + 0.3 × 70 = 81. Based on historical data analysis, quality values ​​between 90 and 100 are considered "excellent," 80-89 are considered "good," 70-79 are considered "acceptable," and less than 70 are considered "unacceptable." Then the quality grade of the wire harness is "good", and the generated quality inspection information will record in detail the various performance values ​​of the wire harness, the calculated quality values, and the corresponding quality grades, etc., to facilitate subsequent quality traceability and production process improvement analysis.

[0027] For example 2, please refer to Figure 2 The present application provides a wire harness processing quality detection system, including: a wire harness information acquisition module, an appearance information analysis module, an electrical performance information analysis module, a mechanical performance information analysis module, a comprehensive analysis module and a detection output module.
