This process involves multiple steps, including the installation of mechanical structures, the joining of electronic components, the filling of lubricants, and the inspection of waterproof seals. After the assembly of watch products, a series of performance tests are required to evaluate whether they meet the design specifications and usage requirements. Traditional watch quality inspection relies on manual inspection, visual inspection and simple functional tests, but it is not accurate for watch quality, which leads to problematic products entering the market or flowing into the hands of consumers, resulting in an increase in scrap rate. This not only increases production costs, but may also damage brand reputation and affect the company's market competitiveness.

[0025] The image data of the appearance of the watch specifically includes the pixel value and two-dimensional coordinates of each pixel point in the appearance image of the watch. The three-dimensional point cloud data inside the watch specifically includes the three-dimensional coordinates of each voxel point. The functional test data includes water tightness pressure value, waterproof depth value, bubble penetration rate value, movement vibration frequency value, balance wheel amplitude value, lubricating oil viscosity value, lubricating oil layer thickness value, pointer rotation torque value, bearing clearance value, and pointer contact force value.

[0026] The two-dimensional coordinate system is established with the upper left corner of the clock appearance image as the far point, the horizontal direction as the X-axis, and the vertical direction as the Y-axis.

[0027] The three-dimensional coordinates take the center point of the dial as the origin, the horizontal axis along the dial is the X-axis, that is, it extends horizontally from the center of the dial to the right, the vertical axis along the dial is the Y-axis, the Y-axis is perpendicular to the X-axis and points in the vertical direction of the dial, and the Z-axis is perpendicular to the plane of the dial and points in the vertical direction of the dial.

[0028] The water tightness pressure value is the maximum water pressure value that a watch can withstand underwater. It can be obtained through a pressure sensor and is used to reflect the waterproof performance of the watch.

[0029] The water resistance depth value is the depth that a watch can withstand underwater without water penetration. It is used to reflect the waterproof ability of a watch.

It can be measured by a viscometer and the measurement results uploaded to a database. The viscosity value of lubricating oil is used to reflect the operating accuracy of the watch movement (because the viscosity of the lubricating oil is appropriate, power can be smoothly transmitted between the parts of the movement to ensure accurate stepping or swinging).

It can be measured by an ultrasonic thickness gauge and the measurement results uploaded to the database.

[0037] The pointer contact force value is the force generated when the pointer contacts the bearing in the watch movement. It can be obtained by the force sensor method, which is used to reflect the smooth rotation of the pointer.

[0038] The specific formula for calculating the assembly quality index of the watch product to be analyzed is as follows: ;in, is the assembly quality index of the watch product to be analyzed, is the appearance integrity index of the watch product to be analyzed, is the appearance coefficient stored in the database, The assembly precision index of the watch product to be analyzed. is the precision coefficient stored in the database, is the functional reliability index of the watch product to be analyzed, is the functional coefficient stored in the database, , is a natural constant and in this embodiment takes a value of 2.71.

[0039] It needs to be explained that , , The specific acquisition process is as follows: read the appearance integrity index, assembly precision index, and functional reliability index of the watch product to be analyzed (it should be noted that the appearance integrity index, assembly precision index, and functional reliability index are all dimensionless indexes, so they can be directly calculated), perform sum analysis, and obtain the assembly quality and value, and perform a proportion analysis of the appearance integrity index, assembly precision index, and functional reliability index of the watch product to be analyzed with the assembly quality and value, and use the proportion analysis results as the corresponding coefficients.

[0040] Specifically, Figure 2 As shown, the specific process of obtaining the appearance integrity index of the watch product to be analyzed is as follows: edge recognition processing is performed on the pixel value of each pixel point in the watch appearance image of the watch product to be analyzed to obtain a number of defect edge pixel points in the watch appearance image of the watch product to be analyzed; each defect edge pixel point in the watch appearance image of the watch product to be analyzed is connected to obtain a number of defect areas in the watch appearance image of the watch product to be analyzed; and a number of pixels in each defect area in the watch appearance image of the watch product to be analyzed and defect edge pixels are summed and analyzed to obtain the area of ​​each defect area in the watch appearance image of the watch product to be analyzed; the two-dimensional coordinates of each defect edge pixel point in each defect area in the watch appearance image of the watch product to be analyzed are comprehensively analyzed to obtain the perimeter of each defect area in the watch appearance image of the watch product to be analyzed, and comprehensive analysis is performed in combination with the area to obtain the appearance integrity index of the watch product to be analyzed.

[0041] The specific formula for calculating the perimeter of each defect area in the watch appearance image of the watch product to be analyzed and the appearance integrity index is as follows: ;in, The first The perimeter of the defect area, The first The defect area The two-dimensional coordinates of the defect edge pixel points, The first The defect area The two-dimensional coordinates of the defect edge pixel points, The first The defect area The two-dimensional coordinates of the defect edge pixel points, The first The two-dimensional coordinates of the first defect edge pixel point in the defect area, is the appearance integrity index of the watch product to be analyzed, is the proportionality factor stored in the database, and in this implementation example, the value is 4. is the value of pi, and in this implementation example, it is taken as 3.14, The first The area of ​​the defect region, , is the number of defective areas, , is the number of pixels on the defect edge.

[0042] The edge recognition processing adopts Canny edge detection, and Canny edge detection identifies the significant edge features in the appearance image, and then extracts the defective edge pixels in the appearance image, including grayscale processing (that is, converting the image into a grayscale image), gradient calculation (that is, using the Sobel operator to calculate the gradient amplitude and direction of the image, so as to find the strong edge of the image), non-maximum suppression (that is, local comparison is performed on each pixel point, and only when the gradient amplitude of the pixel point is the largest, it is considered to be an edge point), double threshold processing (that is, according to the set high threshold and low threshold, the pixel points are classified into strong edges, weak edges and non-edge points), and edge connection (by tracing the weak edge points, connecting the weak edges connected to the strong edge points, and finally forming a complete edge).

[0043] The connectivity processing adopts the depth-first search (used to traverse the pixels in the image and identify the connected areas, that is, starting from a defective edge pixel, recursively checking whether the pixels adjacent to it are connected until all defective edge pixels are traversed).

[0044] In this implementation, the use of algorithms such as Canny edge detection and depth-first search (DFS) can realize automatic detection of defects in the appearance image of the watch, thereby saving a lot of time and reducing human errors. Secondly, by connecting the defect edge pixels, the connected defect area is identified, avoiding misjudgment and ensuring the accuracy of the calculation. Then, the area of ​​the defect area is obtained by summation analysis, and the perimeter is calculated based on the coordinates of the defect edge pixels to obtain the appearance integrity, thereby accurately reflecting the appearance integrity of the watch product. At the same time, by adjusting parameters such as the proportional coefficient, the impact of defects on the appearance integrity index can be flexibly controlled according to actual needs, so as to adjust the quality standards of different products.

[0045] Specifically, the specific steps for obtaining the assembly precision index of the watch product to be analyzed are as follows: perform regional segmentation processing on the three-dimensional coordinates of each voxel point of the watch product to be analyzed, and obtain several key component (such as: gears, springs, bearings) regions of the watch product to be analyzed; perform weighted average processing on the three-dimensional coordinates of each voxel point in each key component region of the watch product to be analyzed, and obtain the three-dimensional coordinates of the center of mass of each key component region of the watch product to be analyzed; conduct comprehensive analysis on the three-dimensional coordinates of the center of mass of each key component region of the watch product to be analyzed, and obtain the horizontal relative angle (i.e. relative to the X-axis), vertical relative angle (i.e. relative to the Y-axis), and vertical relative angle (i.e. relative to the Z-axis) of each group of adjacent key component regions of the watch product to be analyzed, and perform comprehensive analysis in combination with the horizontal relative reference angle, vertical relative reference angle, and vertical relative reference angle of each group of adjacent key component regions stored in the database to obtain the assembly precision index of the watch product to be analyzed.

[0046] The region segmentation process is as follows: preprocessing the three-dimensional coordinates of each voxel point of the clock product to be analyzed (i.e., applying the Sobel operator in three-dimensional space to calculate the gradient and then perform edge detection), and segmenting the preprocessed results using a clustering algorithm (such as DBSCAN).

[0047] The specific formula for calculating the horizontal relative angle of each group of adjacent key component areas of the timepiece product to be analyzed is as follows: ;in, The first The horizontal relative angle of the adjacent key component areas of a group, The first The three-dimensional coordinates of the centroid of the key component area, The first The three-dimensional coordinates of the centroid of the key component area, , is the number of adjacent key component area groups, , is the number of key component regions, and .

[0048] Furthermore, the calculation logic for the vertical relative angle, vertical relative angle and horizontal relative angle of each group of adjacent key component areas of the watch product to be analyzed is consistent, and the calculation formula is also consistent.

[0049] The specific formula for calculating the assembly precision index of the watch product to be analyzed is as follows: ;in, The assembly precision index of the watch product to be analyzed. The first The horizontal relative angle of the adjacent key component areas of a group, The first The horizontal relative reference angle of the adjacent key component areas of a group, is the horizontal factor stored in the database, The first The vertical relative angle of adjacent key component areas of a group, The first The vertical relative angle of adjacent key component areas of a group, is the vertical factor stored in the database, The first The vertical relative angles of adjacent key component areas of a group, The first The vertical relative angles of adjacent key component areas of a group, is the vertical factor stored in the database, , , is the number of adjacent key component area groups.

[0050] It needs to be explained that , , The specific acquisition process is: read the horizontal relative reference angle, vertical relative reference angle, and vertical relative reference angle of each group of adjacent key component areas stored in the database, perform mean analysis, perform normalization processing based on the mean analysis results, and perform sum analysis based on the normalized processing results to obtain the assembly precision and value, and perform proportion analysis on the normalized processing results and the assembly precision and value, and use the proportion analysis results as the corresponding coefficients.

[0051] In this implementation, automated evaluation of assembly accuracy is achieved through region segmentation, centroid calculation, angle analysis, etc., thereby avoiding the difficulty of manual inspection after complex component assembly, thereby improving efficiency and accuracy. Secondly, by calculating the centroid position and relative angle of each key component area, the position and relative relationship of the components in three-dimensional space can be accurately grasped. In watch products with high precision requirements, slight position changes between components will affect the assembly quality, and accurate three-dimensional positioning can ensure assembly accuracy. Finally, by segmenting the component area through a clustering algorithm, independent key components can be effectively identified, avoiding interference from complex backgrounds or overlapping areas, thereby ensuring that each component can be correctly analyzed independently.

[0052] Specifically, Figure 3 As shown, the specific steps for obtaining the functional reliability index of the watch product to be analyzed are as follows: standardize the watertightness pressure value, waterproof depth value, and bubble penetration rate value of the watch product to be analyzed (i.e., remove the unit); comprehensively analyze the watertightness pressure value, waterproof depth value, and bubble penetration rate value of the watch product to be analyzed after the standardization to obtain the waterproof function index of the watch product to be analyzed; and comprehensively analyze the movement vibration frequency value, balance wheel amplitude value, lubricating oil viscosity value, lubricating oil layer thickness value, pointer rotation torque value, bearing clearance value, and pointer contact force value of the watch product to be analyzed to obtain the travel accuracy index of the watch product to be analyzed; and comprehensively analyze the waterproof function index and travel accuracy index of the watch product to be analyzed to obtain the functional reliability index of the watch product to be analyzed.

[0053] Among them, the specific formulas for calculating the waterproof function index and function reliability index of the watch product to be analyzed are as follows: ;in, The waterproof function index of the watch product to be analyzed. is the water tightness pressure value of the watch product to be analyzed after standardization. is the pressure coefficient stored in the database, The water resistance depth value of the watch product to be analyzed after standardization. is the depth coefficient stored in the database, is the bubble penetration rate value of the watch product to be analyzed after standardization. is the permeability coefficient stored in the database, , is the functional reliability index of the watch product to be analyzed, is the waterproof coefficient stored in the database, The time accuracy index of the watch product to be analyzed. is the travel time coefficient stored in the database, , is a natural constant and in this embodiment takes a value of 2.71.

[0054] It needs to be explained that , , The specific acquisition process is: read the watertightness pressure value, waterproof depth value, and bubble penetration rate value of the watch product to be analyzed after standardization, perform sum analysis to obtain the airtightness sum value, and perform proportion analysis on the watertightness pressure value, waterproof depth value, and bubble penetration rate value of the watch product to be analyzed after standardization with the airtightness sum value, and use the proportion analysis result as the corresponding coefficient.

[0055] , The specific acquisition process is: read the waterproof function index and the travel accuracy index of the watch product to be analyzed (it should be noted that the waterproof function index and the travel accuracy index are dimensionless indexes, so they can be directly calculated), perform sum analysis, and obtain the functional reliability value, and perform a proportion analysis on the waterproof function index and the travel accuracy index of the watch product to be analyzed and the functional reliability value, and use the proportion analysis results as the corresponding coefficients.

[0056] In this implementation scheme, standardization is performed to eliminate the influence of different parameter dimensions on the calculation results, ensuring that data are compared and comprehensively analyzed on the same scale, so that different parameters can be reasonably integrated without unit interference, thereby improving the accuracy of the calculation. Secondly, a waterproof function index is obtained by comprehensively analyzing the watertightness pressure value, waterproof depth value, and bubble penetration rate, so as to comprehensively evaluate the sealing performance of the watch underwater. Through a comprehensive analysis of parameters such as the movement vibration frequency value, the balance wheel amplitude value, the lubricating oil viscosity value, and the lubricating oil layer thickness value, the travel accuracy index is obtained, so as to quantify the travel accuracy of the watch, thereby providing a more comprehensive and accurate evaluation. Finally, through the analysis of the functional reliability index, a comprehensive evaluation index for product quality is provided, and an intuitive reliability value is provided to consumers.

[0062] , The specific acquisition process is: read the power transmission stability index and pointer movement smoothness index of the watch product to be analyzed (it should be noted here that the power transmission stability index and the pointer movement smoothness index are dimensionless indexes, so they can be directly calculated), perform sum analysis to obtain the travel time accuracy and value, and perform ratio analysis on the power transmission stability index and pointer movement smoothness index of the watch product to be analyzed and the travel time accuracy and value, and use the ratio analysis results as the corresponding coefficients.

[0063] The specific implementation example of calculating the travel time accuracy index of the timepiece product to be analyzed is as follows, and the following data are available: The movement vibration frequency value of the watch product to be analyzed is (unit: Hz): 4.20.

[0064] The amplitude value of the balance wheel of the watch product to be analyzed is (unit: degree): 312.00.

[0065] The viscosity value of the lubricating oil of the watch product to be analyzed is (unit: cP): 250.00.

[0066] The thickness of the lubricating oil layer of the watch product to be analyzed is (unit: μm): 10.23.

[0067] The pointer rotation torque value of the watch product to be analyzed is (unit: mN·m): 0.50.

[0068] The bearing clearance value of the watch product to be analyzed is (unit: mm): 0.03.

[0070] The reference value of the movement vibration frequency of the watch product to be analyzed is (unit: Hz): 4.00.

[0071] The reference value of the balance wheel amplitude of the watch product to be analyzed is (unit: degree): 280.00.

[0072] The reference value of the lubricating oil viscosity of the watch product to be analyzed is (unit: cP): 220.00.

[0073] The reference value of the lubricating oil layer thickness of the watch product to be analyzed is (unit: μm): 8.00.

[0074] The reference value of the pointer rotation torque of the watch product to be analyzed is (unit: mN·m): 0.30.

[0075] The reference value of the bearing clearance of the watch product to be analyzed is (unit: mm): 0.02.

[0076] The reference value of the pointer contact force of the watch product to be analyzed is (unit: N): 0.03.

[0077] The vibration coefficient stored in the database is approximately: 0.38.

[0078] The amplitude coefficient stored in the database is approximately: 0.26.

[0079] The viscosity coefficient stored in the database is approximately: 0.23.

[0080] The thickness factor stored in the database is approximately: 0.13.

[0081] The torque coefficient stored in the database is approximately: 0.42.

[0082] The gap factor stored in the database is approximately: 0.36.

[0083] The contact coefficient stored in the database is approximately: 0.22.

[0084] The dynamic coefficient stored in the database is approximately: 0.49.

[0085] The pointer stability coefficient stored in the database is approximately: 0.51.

[0086] Substituting the above data into the formula of the power transmission stability index of the watch product to be analyzed, we get: The power transmission stability index of the watch product to be analyzed = ln (1 + (1 / ((0.38*√|1-(4.20 / 4.00)|+0.26*|1-(312.00 / 280.00)|+0.23*|1-(250.00 / 220.00)|+0.13*|1-(10.23 / 8.00)|))))≈1.87.

[0087] The pointer movement smoothness index of the watch product to be analyzed = ((1 / ((0.42*|1-(0.50 / 0.30)|+0.36*|1-(0.03 / 0.02)|+0.22*|1-(0.04 / 0.03)|)))≈1.88.

[0088] The timekeeping accuracy index of the watch product to be analyzed = arctan ((0.49*1.87+0.51*1.88) / (2.71-1)) = 1.08.

[0089] In this implementation scheme, by analyzing multiple key parameters separately, a comprehensive evaluation of the accuracy of the watch's travel time is ensured. Different factors have different effects on the travel time. It is difficult to fully capture the effect of each factor on the overall accuracy by analyzing each factor alone. Comprehensive analysis can better reflect the interaction of various factors. Secondly, by comprehensively analyzing the movement vibration frequency value and the reference value, and the balance wheel amplitude value and the reference value, the stability of the power transmission process can be effectively evaluated. The viscosity and layer thickness of the lubricating oil also have an important influence on the friction, wear and movement smoothness of mechanical parts. The analysis of these factors helps to determine the reliability of power transmission, and analyzes the actual values ​​and reference values ​​of the pointer torque, bearing clearance and pointer contact force, which can deeply evaluate the smoothness of the pointer movement, thereby improving the accuracy of the travel time and avoiding errors caused by unstable pointer movement.

[0090] Specifically, the specific steps for taking corresponding assembly repair measures based on judgment and analysis are as follows: if the assembly quality index of the watch product to be analyzed is lower than or equal to the preset assembly quality threshold, the watch product to be analyzed will be marked as an unqualified product, and repair measures will be taken (i.e., rework, repairing errors or omissions in the assembly process, including disassembling and reassembling parts, etc.; recalibrating the assembly accuracy, re-adjusting the accuracy of the movement according to the precision requirements of the product, ensuring the accuracy of the clock's travel, and avoiding time errors caused by assembly errors; lubricating oil adjustment: ensuring that the lubrication system of the mechanical part works normally, checking and replenishing the lubricating oil, and preventing wear or jamming of parts); if the assembly quality index of the watch product to be analyzed is higher than the preset assembly quality threshold, the watch product to be analyzed will be marked as a qualified product, and the product will be packaged.

[0091] In this implementation plan, by setting a clear assembly quality threshold and taking corresponding repair measures according to actual conditions, it is ensured that only products that meet quality standards enter the market, which helps to significantly reduce the circulation risk of unqualified products, thereby ensuring that consumers obtain high-quality watches. By taking repair measures such as rework, precision calibration and lubricant adjustment for unqualified products, entire batches of scrap due to minor defects are avoided, so that originally unqualified products can meet the standards again, reduce the scrap rate, and thus reduce production costs and waste of resources. By recalibrating assembly accuracy and adjusting lubricants and other measures, the product's timing accuracy and mechanical properties are ensured, and the long-term stability of the watch is enhanced.

[0092] In summary, this application has at least the following effects: By acquiring the internal 3D point cloud data of the watch after assembly and analyzing it to obtain the assembly precision index, it is possible to accurately evaluate whether the internal structure of the watch after assembly meets the design standards, and then detect tiny errors after assembly, thereby ensuring the precision and long-term stability of the watch product.

[0093] By comprehensively analyzing the appearance integrity index, assembly precision index and functional reliability index, a comprehensive quality assessment of watch products is conducted. The functional reliability index analyzed by the second data analysis module ensures that the product not only meets the standards in appearance and assembly, but also maintains long-term stability and reliability in function. This allows manufacturers to fully understand the assembly quality of the product, thereby reducing after-sales service and repair costs caused by poor product functions, and then improving the overall market competitiveness of the product.

[0094] By comparing and analyzing the assembly quality index of watch products with the preset quality threshold, if the product does not meet the quality standard, it will be automatically marked as an unqualified product, thereby preventing unqualified products from entering the market and repairing the quality of unqualified watch products, thereby improving the final qualification rate of the product.
