Description

Technical Field

[0001] The present invention relates to the technical field of product appearance detection, and specifically to a precision detection method for the outer ring case of an intelligent wearable watch based on an optical probe. Background Art

[0002] The precision detection of the outer ring case of a watch is a key link to ensure the quality of the watch. Its detection ensures the assembly fit and appearance texture between the outer ring and the case, provides technical support for the sealing, durability and aesthetics of the watch, and runs through the entire quality control process of watch production.

[0003] The invention patent application with the application number 202310708907.2 discloses a precision manufacturing method for the case of a precious metal watch, including the following steps: Step 1, raw material melting; Step 2, component detection; Step 3, stamping forming; Step 4, dimension detection; Step 5, tempering and repressing; Step 6, precision machining; Step 7, repeated detection; Step 8, post-treatment of the case; characterized in that: in the above Step 1, an appropriate amount of gold is taken, and a small amount of silver, palladium, nickel, zinc, and copper are added, and high-temperature melting is carried out; in the above Step 2, after the mixed metal cools, an alloy analyzer is used to detect whether its metal components meet the standards; in the above Step 3, a thicker mixed metal plate is processed into a metal thin plate with an expected thickness, and then sent into a stamping device for preliminary forming; in the above Step 4, the preliminarily formed metal plate needs to be detected for its shape and overall dimensions; in the above Step 5, according to whether the detection result of the shape and dimensions is qualified, it is decided whether to carry out tempering and repressing on the case in the next step; in the above Step 6, after the overall rough blank of the case is formed, it is sent into a numerical control machine tool for precision machining according to specific data; in the above Step 7, after the case is completely formed, final tests are carried out, including quality and dimension detection; in the above Step 8, the case with qualified quality is subjected to finishing treatment to remove burrs and other problems.

[0004] However, no matter how high-precision the manufacturing method is, over time, errors in manufacturing equipment will accumulate, resulting in defects in the outer ring cases of the produced watches.

[0005] Therefore, we propose a precision detection method for the outer ring case of an intelligent wearable watch based on an optical probe. Summary of the Invention

[0006] In view of the above-mentioned disadvantages of the prior art, the present invention provides a method for detecting the accuracy of the outer case of an intelligent wearable watch based on an optical probe, which can effectively solve the problems of the prior art.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions;

[0008] The present invention discloses a method for detecting the accuracy of the outer case of an intelligent wearable watch based on an optical probe, including:

[0009] Prepare a standard sample case, fix the standard sample case, carry an optical probe based on a robotic arm to align with the standard sample case and move along a predetermined path. During the movement, control the operation of the optical probe and collect the return optical signal of the optical signal emitted by the optical probe in real time; during the operation of the robotic arm and the optical probe, collect the operation state parameters of the robotic arm and the optical probe in real time, set the standard operation state parameter range of the robotic arm and the optical probe, and determine whether the collected operation state parameters of the robotic arm and the optical probe are all within the corresponding standard operation state parameter range; if the determination result is no, debug and calibrate the robotic arm and the optical probe, and jump to the stage of carrying the optical probe based on the robotic arm to align with the standard sample case and move along the predetermined path, and execute in sequence; if the determination result is yes, record the currently collected return optical signal as a valid return optical signal; sample the outer case of the watch produced in batches according to the standard sample case specification parameters, synchronously mark the production time stamp for each outer case sample of the watch, and detect each outer case sample of the watch based on the time stamp marked on each outer case sample of the watch to obtain the return optical signal; record the obtained return optical signal as a sample return optical signal, synchronously mark the sample return optical signal with the time stamp marked on its corresponding outer case sample of the watch, and use each sample return optical signal with a time stamp mark as a comparison target to calculate the similarity with the corresponding return optical signal of the standard sample case; obtain the similarity calculation result, set a qualified determination threshold, compare based on the qualified determination threshold and the similarity calculation result, determine whether each outer case sample of the watch from which the similarity calculation result is obtained is qualified, and trace the unqualified outer case of the watch.

[0010] Furthermore, the predetermined path is composed 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 case, and after the return optical signal is collected, a cloud database or an application data storage element is synchronously created to store the return optical signal;

[0011] Among them, the stored return optical signal is synchronously configured with a time series, and during the storage stage of the return optical signal, it is stored in sequence based on the time series. During the process of controlling the movement of the optical probe by the robotic arm, the light signal emitting end of the optical probe moves parallel on a unique plane.

[0012] Furthermore, the predetermined path consists of several sets of position coordinates. The predetermined path is a closed-loop path, and the predetermined path is the same as the contour of the detection surface of the sample shell. After the return optical signal is collected, a cloud database or an application data storage component is synchronously created to store the return optical signal;

[0013] Among them, the stored return optical signal is synchronously configured with a time series. During the storage stage of the return optical signal, it is stored based on the time series sorting. When the optical probe is controlled by the robotic arm to move, the light signal emitting end of the optical probe is located in a unique plane and moves parallel.

[0014] Furthermore, after the return optical signal of the standard sample shell is stored, it is synchronously monitored whether the return optical signal is recorded as a valid return optical signal. When the monitoring result is no, the stored return optical signal is synchronously deleted.

[0015] Furthermore, when sampling the outer watch case in mass production, the sampling of the outer watch case follows:

[0016] The larger the number of outer watch cases produced in a single batch, the larger the number of samples;

[0017] The first and the last produced outer watch cases in the outer watch cases produced in a single batch are the sampling targets;

[0018] The operating state parameters of the outer watch case production equipment are monitored in real time. Based on a specified frequency, the operating state parameters of the outer watch case production equipment are continuously applied to analyze the degree of operation fluctuation and disorder of the outer watch case production equipment. A disorder determination threshold is set. Based on the disorder determination threshold, it is determined whether the operating state of the outer watch case production equipment corresponding to each analysis result is stable. When the determination result is no, the outer watch cases produced at the time of the source time of the operating state parameters of the outer watch case production equipment and the outer watch cases produced at adjacent times are used as sampling targets.

[0019] Furthermore, the operation of detecting the outer watch case sample is the same as the operation of collecting the return optical signal of the standard sample shell, and when the outer watch case sample is fixed, the fixed posture is exactly the same as that of the standard sample shell.

[0020] Furthermore, the analysis logic of the degree of operation fluctuation and disorder of the outer watch case production equipment is expressed as:

[0021] The operating state parameters of the outer watch case production equipment include: temperature, pressure, motor speed, vibration amplitude;

[0022]

[0023] Where: S is the degree of operational fluctuation and disorder of the production equipment for the outer watch case; 4 represents the types of operational state parameters of the production equipment for the outer watch case; ω i is the configuration weight of the i-th type of parameter; α is the balance coefficient; X i,norm is the normalized average value of the i-th type of parameter; F i is the fluctuation coefficient of the i-th type of parameter;

[0024] Among them, the value range of the balance coefficient α is 0 ≤ α ≤ 1. The larger S is, the more disordered the operation fluctuation of the production equipment for the outer watch case is. The configuration weights of the operational state parameters of each production equipment for the outer watch case are all greater than zero and follow If S is less than the disorder determination threshold, it is determined that the operation state of the production equipment for the outer watch case is stable.

[0025] Furthermore, the calculation logics of the normalized average value and the fluctuation coefficient of the operational state parameters of each production equipment for the outer watch case are the same;

[0026] The larger the logarithmic value is, the more the parameter deviates from the normal state:

[0027]

[0028] The smaller the logarithmic value is, the more the parameter deviates from the normal state:

[0029]

[0030] Fluctuation coefficient:

[0031] Where: m is the total amount of the i-th type of parameter; X j is the value of the j-th parameter in the i-th type of parameter; X j,max , X j,min are the maximum and minimum values within the normal operation range of the i-th type of parameter; σi is the standard deviation of the i-th type of parameter within a predetermined time window; μi is the average value of the i-th type of parameter within a predetermined time window.

[0032] Furthermore, the similarity calculation formula between the sample return optical signal and the corresponding return optical signal of the standard sample case is:

[0033]

[0034] Where: SIMM(X,Y) is the similarity between the sample return optical signal and the corresponding return optical signal of the standard sample case based on the spatio-temporal dynamic field; is the reduced Planck constant; ψ X (t), ψ Y (t) are the quantum state wave functions of the sample return optical signal and the corresponding return optical signal of the standard sample case evolving with time; is the Hamiltonian operator; <|, |> are the bra symbol and ket symbol respectively;

[0035] where ψ X (t) and ψ Y (t) have the same calculation logic. Taking ψ X (t) as an example, ψ X (t) = a(t)e cφ(t) ; in the formula: a(t) is the complex amplitude; cφ(t) is the phase factor.

[0036] Furthermore, when tracing the unqualified outer watch case, the outer watch cases produced in adjacent time sequences of the unqualified outer watch case samples are used as the capture targets. For the return optical signals belonging to the standard sample case for the capture targets, the operation of calculating the similarity of the return optical signals is performed. When the similarity calculation result does not meet the qualified determination threshold, the capture of the outer watch case samples produced in adjacent time sequences is performed again, and the similarity of its return optical signal with that belonging to the standard sample case is calculated again. The qualified determination threshold is applied for re-comparison, and so on, until the comparison result with the qualified determination threshold meets the qualified determination threshold, and then it ends. All the captured outer watch cases are unqualified outer watch cases.

[0037] Adopting the technical solution provided by the present invention, compared with the known prior art, it has the following beneficial effects:

[0038] The present invention provides a method for detecting the accuracy of the outer watch case of an intelligent wearable watch based on an optical probe. During the execution of this method, the robotic arm carries the optical probe to move along a closed-loop predetermined path that is the same as the contour of the sample case detection surface and collect the return optical signal, and the optical signal emitting end moves parallel in a unique plane, which can ensure the standardization of the detection path and the consistency of the optical signal collection, and improve the reliability of the detection data;

[0039] Moreover, multiple operating state parameters of the robotic arm and the optical probe are collected in real time and compared with the standard interval. Only after debugging and calibration to meet the requirements is the return optical signal recorded as valid, which ensures the stability of the detection process from the source. When sampling, the samples are scientifically determined according to the production quantity, time and equipment operating state, which not only ensures the representativeness of the samples but also can timely capture the products during equipment fluctuations; the similarity of the sample return optical signal with a time stamp and the standard signal is calculated based on the spatio-temporal dynamic field, and combined with the qualified determination threshold to determine whether the product is qualified, realizing high-precision quantitative detection. For unqualified products, the products produced in adjacent time sequences are used as the targets for gradual tracing, which can accurately locate the range of unqualified products and improve the efficiency and accuracy of production quality control.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0043] The following further describes the present invention with reference to the embodiments.

[0044] Embodiment:

[0045] The accuracy detection method for the outer ring case of an intelligent wearable watch based on an optical probe in this embodiment is as Figure 1 shown and includes: Step 1: Prepare a standard sample case, fix the standard sample case, and control the optical probe carried by the robotic arm to move along a predetermined path to align with the standard sample case. During the movement, control the operation of the optical probe and collect the return optical signal of the optical signal emitted by the optical probe in real time;

[0046] The predetermined path consists of several groups of position coordinates. The predetermined path is a closed-loop path, and the predetermined path is the same as the contour of the detection surface of the sample case. After the return optical signal is collected, a cloud database or an application data storage element is synchronously created to store the return optical signal;

[0047] Among them, the stored return optical signal is synchronously configured with a time series. During the storage stage of the return optical signal, it is stored in sequence based on the time series. During the movement of the optical probe controlled by the robotic arm, the light signal emitting end of the optical probe moves parallelly in a unique plane;

[0048] When any one of the collected operating state parameters of the robotic arm and the optical probe is not within the corresponding standard operating state parameter range, perform the debugging and calibration operations of the robotic arm and the optical probe, and refresh the step execution until the determination result is yes and then end;

[0049] The operating state parameters of the robotic arm and the optical probe include: the operating distance of each link, the operating speed of each link, the operating power, the joint rotation angle, the joint rotation speed, the light intensity, the frequency, the noise level, the spatial resolution, the distance resolution, and the trigger delay;

[0050] Among them, when debugging and calibrating the robotic arm and the optical probe, refer to the preset standard operating state parameter range of the robotic arm and the optical probe for debugging and calibration, so that the operating state parameters of the robotic arm and the optical probe after debugging and calibration conform to the corresponding standard operating state parameter range;

[0051] After the return optical signal of the standard sample shell is stored, synchronously monitor whether the return optical signal is recorded as a valid return optical signal. When the monitoring result is no, synchronously delete the stored return optical signal;

[0052] Step 2: During the operation of the robotic arm and the optical probe, real-time collect the operating state parameters of the robotic arm and the optical probe, set the standard operating state parameter range of the robotic arm and the optical probe, and determine whether the collected operating state parameters of the robotic arm and the optical probe are all within the corresponding standard operating state parameter range;

[0053] Step 3: If the determination result is no, debug and calibrate the robotic arm and the optical probe, and jump to the stage where the robotic arm carries the optical probe to align with the standard sample shell and move along a predetermined path, and execute in sequence;

[0054] Step 4: If the determination result is yes, record the currently collected return optical signal as a valid return optical signal;

[0055] Step 5: Sample the outer watch cases produced in batches according to the standard sample shell specifications. Synchronously mark the production timestamp for each outer watch case sample. Based on the timestamps marked on each outer watch case sample, detect each outer watch case sample to obtain the return optical signal;

[0056] When sampling the outer watch cases produced in batches, the sampling of the outer watch cases follows:

[0057] The larger the number of outer watch cases produced in a single batch, the more the sampling quantity;

[0058] The first and the last produced outer watch cases in a single batch of produced outer watch cases are the sampling targets;

[0059] Real-time monitor the operating status parameters of the production equipment for the outer ring case of the watch. Continuously analyze the operating fluctuation and disorder degree of the production equipment for the outer ring case of the watch based on the specified frequency by applying the operating status parameters of the production equipment for the outer ring case of the watch. Set the disorder judgment threshold. Based on the disorder judgment threshold, determine whether the operating status of the production equipment for the outer ring case of the watch corresponding to each analysis result is stable. When the judgment result is negative, capture the outer ring cases of the watch produced at the source time of the operating status parameters of the production equipment for the outer ring case of the watch and the outer ring cases of the watch produced at the adjacent time as the sampling targets;

[0060] The operation of detecting the sample of the outer ring case of the watch is the same as the operation of collecting the return optical signal for the standard sample case. And when fixing the sample of the outer ring case of the watch, the fixing posture is exactly the same as that of the standard sample case;

[0061] The analysis logic of the operating fluctuation and disorder degree of the production equipment for the outer ring case of the watch is expressed as:

[0062] The operating status parameters of the production equipment for the outer ring case of the watch include: temperature, pressure, motor speed, vibration amplitude;

[0063]

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

[0065] Among them, the value range of the balance coefficient α is 0 ≤ α ≤ 1. The larger S is, the more disordered the operation fluctuation of the production equipment for the outer ring case of the watch is. The configuration weights of the operating status parameters of each production equipment for the outer ring case of the watch are all greater than zero and obey If S is less than the disorder judgment threshold, it is determined that the operating status of the production equipment for the outer ring case of the watch is stable;

[0066] The calculation logics of the normalized average value and the fluctuation coefficient of the operating status parameters of each type of production equipment for the outer ring case of the watch are the same;

[0067] The parameter with a larger logarithm value is more deviated from the normal state:

[0068]

[0069] The parameter with a smaller logarithm value is more deviated from the normal state:

[0070]

[0071] Fluctuation coefficient:

[0072] Where: m is the total amount of the i-th type of parameter; X j is the value of the j-th parameter among the i-th type of parameters; X j,max 、X j,min are the maximum and minimum values within the normal operating range of the i-th type of parameter; σ i is the standard deviation of the i-th type of parameter within a predetermined time window; μ i is the average value of the i-th type of parameter within a predetermined time window;

[0073] Through the above logical formula, the degree of operation fluctuation and disorder of the watch outer ring case production equipment is calculated, so as to provide support for the selection of the watch outer ring case sample based on this as a reference.

[0074] Step 6: Denote the acquired return optical signal as the sample return optical signal, synchronously mark the sample return optical signal with the time stamp marked on the corresponding watch outer ring case sample, and use each sample return optical signal with a time stamp mark as a comparison target to calculate the similarity with the corresponding return optical signal of the standard sample case;

[0075] Step 7: Obtain the similarity calculation result, set the qualified judgment threshold, compare based on the qualified judgment threshold and the similarity calculation result, determine whether the watch outer ring case sample from which each similarity calculation result is derived is qualified, and trace the unqualified watch outer ring cases;

[0076] The similarity calculation formula between the sample return optical signal and the corresponding return optical signal of the standard sample case is:

[0077]

[0078] Where: SIMM(X,Y) is the similarity between the sample return optical signal and the corresponding return optical signal of the standard sample case based on the spatio-temporal dynamic field; is the reduced Planck constant; ψ X (t), ψ Y (t) are the quantum state wave functions of the sample return optical signal and the corresponding return optical signal of the standard sample case evolving with time; is the Hamiltonian operator; <|,|> are the left ket symbol and the right ket symbol;

[0079] Among them, ψ X (t), ψ Y (t) have the same calculation logic. Taking ψ X (t) as an example, ψ X (t) = a(t)e cφ(t) ; Where: a(t) is the complex amplitude; cφ(t) is the phase factor;

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

[0081] Through the above formula, the similarity between the sample return optical signal and the return optical signal corresponding to the standard sample case is calculated, and then based on the comparison with the qualified determination threshold, the qualification of the watch outer case sample is determined;

[0082] When tracing the unqualified watch outer case, the watch outer case produced in the adjacent time sequence of the unqualified watch outer case sample is used as the capture target, and the return optical signal similarity calculation operation is performed on the capture target in combination with the return optical signal of the standard sample case. When the similarity calculation result does not meet the qualified determination threshold, the capture of the watch outer case sample produced in the adjacent time sequence is performed again, and the similarity between it and the return optical signal of the standard sample case is calculated again, and the qualified determination threshold is applied for re-comparison, and so on, until the comparison result with the qualified determination threshold meets the qualified determination threshold, and then it ends. All the captured watch outer cases are unqualified watch outer cases.

[0083] In summary, in the above embodiments, the method uses a robotic arm to carry an optical probe to move parallel along a closed-loop predetermined path to collect optical signals, ensuring the standardization of the detection path and signal consistency; real-time monitoring of the operating parameters such as the link distance and light intensity of the robotic arm and the probe, locking the effective signal after debugging and calibration to the standard interval, ensuring the detection stability from the source; the sampling rule combines the production quantity, the first and last pieces, and the equipment operation fluctuations to accurately capture the risk samples; using the spatio-temporal dynamic field similarity algorithm with time stamps to quantitatively determine the qualification, and accurately positioning the unqualified product range through adjacent time sequence tracing, significantly improving the detection accuracy and quality control efficiency, and providing an efficient and reliable precision detection solution for the mass production of smart wearable watch cases.

[0084] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
