Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] The present invention will be further described below with reference to embodiments.

[0044] Example:

[0045] This embodiment presents a method for detecting the accuracy of the outer bezel of a smart wearable watch based on an optical probe, such as... Figure 1 As shown, it includes: Step 1: Prepare a standard sample shell, fix the standard sample shell, and move the robotic arm carrying the optical probe along a predetermined path to align with the standard sample shell. During the movement, control the operation of the optical probe and collect the return light signal of the light signal emitted by the optical probe in real time.

[0046] The predetermined path consists of several sets of position coordinates. The predetermined path is a closed loop path. The predetermined path is the same as the detection surface contour of the sample shell. After the return light signal is collected, a cloud database or application data storage element is created to store the return light signal.

[0047] Among them, the stored return optical signal is synchronously configured with a time series. During the storage stage, the return optical signal is stored in order based on the time series. During the movement of the optical probe controlled by the robotic arm, the optical signal emitting end of the optical probe moves parallel to a single plane.

[0048] If any of the collected operating status parameters of the robotic arm and optical probe are not within the corresponding standard operating status parameter range, the debugging and calibration operation of the robotic arm and optical probe shall be performed, and the step execution shall be refreshed until the judgment result is yes.

[0049] The operation state parameters of the mechanical arm and the optical probe include: operation distance of each connecting rod, operation speed of each connecting rod, operation power, joint rotation angle, joint rotation speed, light intensity, frequency, noise level, spatial resolution, distance resolution, and trigger delay.

[0050] During the debugging and calibration of the mechanical arm and the optical probe, the standard operation state parameter intervals of the mechanical arm and the optical probe are referred to for debugging and calibration, so that the operation state parameters of the debugged and calibrated mechanical arm and the optical probe meet the corresponding standard operation state parameter intervals.

[0051] After the standard sample shell returns the light signal, it is stored, and whether the return light signal is recorded as an effective return light signal is monitored synchronously. If the monitoring result is no, the stored return light signal is deleted synchronously.

[0052] Step 2: During the operation of the mechanical arm and the optical probe, the operation state parameters of the mechanical arm and the optical probe are collected in real time, the standard operation state parameter intervals of the mechanical arm and the optical probe are set, and it is determined whether the collected operation state parameters of the mechanical arm and the optical probe are in the corresponding standard operation state parameter intervals.

[0053] Step 3: If the determination result is no, the mechanical arm and the optical probe are debugged and calibrated, and the process jumps to the stage of moving the standard sample shell according to the predetermined path based on the mechanical arm carrying the optical probe, and is executed in sequence.

[0054] Step 4: If the determination result is yes, the currently collected return light signal is recorded as an effective return light signal.

[0055] Step 5: The watch outer ring watch case produced in batches according to the standard sample shell specification parameters is sampled, and each watch outer ring watch case sample is labeled with a production timestamp synchronously. Based on the timestamp labeled on each watch outer ring watch case sample, each watch outer ring watch case sample is detected to obtain a return light signal.

[0056] When sampling in the batch-produced watch outer ring watch case, the sampling of the watch outer ring watch case is subject to:

[0057] The more the number of single-batch-produced watch outer ring watch cases, the more the sampling number.

[0058] The first watch outer ring watch case and the last watch outer ring watch case produced in the single-batch-produced watch outer ring watch case are the sampling targets.

[0059] Real-time monitoring of watch outer ring watch case production equipment running state parameters, based on the specified frequency continuous application watch outer ring watch case production equipment running state parameter analysis watch outer ring watch case production equipment running fluctuation disorder degree, set disorder judgment threshold, based on the disorder judgment threshold to determine whether the corresponding watch outer ring watch case production equipment running state is stable for each analysis result, when the capture determination result is no, the watch outer ring watch case production equipment running state parameter source time production watch outer ring watch case and adjacent time production watch outer ring watch case as sampling target;

[0060] The operation of detecting the watch outer ring watch case sample is consistent with the operation of returning the light signal collection of the standard sample case, and when the watch outer ring watch case sample is fixed, the fixed posture is completely consistent with that of the standard sample case;

[0061] The analysis logic of the fluctuation disorder degree of the watch outer ring watch case production equipment running is:

[0062] The watch outer ring watch case production equipment running state parameters include: temperature, pressure, motor speed, vibration amplitude;

[0063]

[0064] In the formula: S is the fluctuation disorder degree of the watch outer ring watch case production equipment running; 4 represents the type of watch outer ring watch case production equipment running state parameter; ω i is the configuration weight of the i-th type parameter; α is the balance coefficient; X i,norm is the normalized average value of the i-th type parameter; F i is the fluctuation coefficient of the i-th type parameter;

[0065] Wherein, the balance coefficient α is in the range of 0≤α≤1, the larger S is, the more fluctuation and disorder of the watch outer ring watch case production equipment running, the configuration weight of each watch outer ring watch case production equipment running state parameter is greater than zero, and is subject to S is less than the disorder judgment threshold, then it is determined that the watch outer ring watch case production equipment running state is stable;

[0066] The calculation logic of the normalized average value and the fluctuation coefficient of each type of watch outer ring watch case production equipment running state parameter is the same;

[0067] The larger the numerical value is, the more the parameter deviates from the normal state:

[0068]

[0069] The smaller the numerical value is, the more the parameter deviates from the normal state:

[0070]

[0071] Fluctuation coefficient:

[0072] wherein: m is the total amount of the i-th type of parameters; X j is the value of the j-th parameter in the i-th type of parameters; X j,max , X j,min is the maximum and minimum value of the i-th type of parameters in the normal operation range; σ i is the standard deviation of the i-th type of parameters in the predetermined time window; μ i is the average value of the i-th type of parameters in the predetermined time window;

[0073] Through the above logical formula, the running fluctuation and disorder degree of the watch outer ring watch case production equipment is calculated, thereby providing support for the selection of the watch outer ring watch case sample.

[0074] Step 6: The obtained return light signal is marked as a sample return light signal, and the time stamp corresponding to the sample return light signal is synchronously marked, and each sample return light signal with a time stamp is marked as a comparison target and a standard sample shell corresponding return light signal for similarity calculation;

[0075] Step 7: Obtain the similarity calculation result, set a qualified judgment threshold, compare the qualified judgment threshold with the similarity calculation result, and determine whether the watch outer ring watch case sample of each similarity calculation result is qualified, and trace the unqualified watch outer ring watch case;

[0076] The similarity calculation formula of the sample return light signal and the standard sample shell corresponding return light signal is:

[0077]

[0078] wherein: SIMM(X, Y) is the similarity of the sample return light signal and the standard sample shell corresponding return light signal based on the space-time dynamic field; is the reduced Planck constant; ψ X (t), ψ Y (t) is the quantum state wave function of the sample return light signal and the standard sample shell corresponding return light signal evolving with time; is the Hamiltonian operator; and, are left arrow symbol and right arrow symbol;

[0079] wherein, ψ X (t), ψ Y (t) have the same calculation logic, and take ψ X (t) as an example, ψ X (t) = a(t)e cφ(t) ; wherein: a(t) is a complex amplitude; and cφ(t) is a phase factor;

[0080] It should be noted that t0→t1 represents the time interval for signal acquisition;

[0081] The similarity between the sample's returned light signal and the corresponding returned light signal of the standard sample case is calculated using the above formula. Then, based on the comparison with the pass / fail threshold, the watch bezel case sample is judged to be qualified.

[0082] When tracing the source of defective watch bezels, watch bezels produced in the adjacent time series of the defective watch bezel sample are used as the capture target. The similarity of the returned light signal of the captured target with that of the standard sample is calculated. If the similarity calculation result does not meet the acceptance threshold, the capture of watch bezel samples produced in the adjacent time series is performed again, and the similarity between them and the returned light signal of the standard sample is calculated again. The acceptance threshold is then applied for comparison again. This process is repeated until the comparison result meets the acceptance threshold, at which point the process ends, and all captured watch bezels are determined to be defective.

[0083] In summary, the method described in the above embodiments collects light signals by moving a robotic arm carrying an optical probe along a predetermined closed-loop path, ensuring the consistency between the detection path and the signal. It monitors operational parameters such as the linkage distance and light intensity of the robotic arm and probe in real time, and locks in valid signals after calibration to the standard range, thus ensuring detection stability from the source. Sampling rules, combined with production quantity, first and last pieces, and equipment operational fluctuations, accurately capture risk samples. A spatiotemporal dynamic field similarity algorithm with timestamps is used to quantify the pass / fail status, and adjacent time-series tracing is used to accurately locate the range of non-conforming products, significantly improving detection accuracy and quality control efficiency, providing an efficient and reliable precision detection solution for the mass production of smart wearable watch cases.
