Description

Technical Field

[0001] This invention relates to the field of mechanical watch technology, and in particular to a method, apparatus, computer device, and storage medium for polarization correction of mechanical watches. Background Technology

[0002] In mechanical watches with a fork escapement mechanism, the disc pin on the balance wheel needs to be installed on the center line of the escapement system, meaning the center line of the disc pin on the balance wheel should coincide with the line connecting the center of the balance wheel and the escape fork pin. (See [reference needed]). Figure 1 This ensures that the balance wheel and hairspring system are in a balanced position. When the balance wheel is stationary, the disc pin on the balance wheel deviates from the center line of the escapement system, causing the balance wheel to swing with inconsistent amplitudes from left to right, resulting in a polarization phenomenon.

[0003] Currently, when using a watch calibrator to identify the polarization data of a mechanical watch, the position of the balance wheel is typically adjusted manually to position it near or at the center line of the escapement system. This keeps the watch's polarization within acceptable limits, ensuring accurate timekeeping. However, due to the small size of the movement components in a mechanical watch, manually adjusting the balance wheel's position cannot achieve rapid and quantitative correction of the watch's polarization. Furthermore, the polarization data identified by the calibrator cannot determine the rotation direction of the balance wheel (or the balance wheel), making it impossible to quickly determine the direction of polarization, i.e., which direction the balance wheel's position needs to be adjusted. Summary of the Invention

[0004] This invention provides a method, apparatus, computer device, and storage medium for polarization correction of mechanical watches, aiming to solve the problems in the prior art where adjusting the position of the disc pin manually cannot achieve rapid and quantitative correction of the polarization of mechanical watches, and cannot quickly determine which direction the position of the disc pin needs to be adjusted.

[0041] In mechanical watches with a forklift escapement, the balance wheel 4 and hairspring 9 form an oscillating system with a fixed period T. This system receives energy periodically from the escapement to maintain its cyclical operation. (See also...) Figure 1 and Figure 2 Theoretically, the equilibrium position of the balance wheel and hairspring system is when the center line of the disc pin 41 on the balance wheel 4 coincides with the center line 6 connecting the balance wheel 4 and the escapement fork shaft (i.e., the center line of the escapement system). That is, when the disc pin 41 on the balance wheel 4 is in the equilibrium position, its center line coincides exactly with the center line 6 connecting the balance wheel 4 and the escapement fork shaft. Furthermore, when the mechanical watch is running, the escapement mechanism at the equilibrium position will produce three distinct impact sounds: release sound a, impulse sound b, and drop sound c. These three impact sounds constitute the watch's chime signal at this equilibrium position. If the disc pin 41 on the balance wheel 4 is in the equilibrium position when the balance wheel 4 is stationary, the time elapsed for the two half-cycles within one period T (defined as the time it takes for the balance wheel and hairspring system to travel from the equilibrium position to the amplitude position and then back to the equilibrium position) is the same. In other words, the time interval between adjacent chime signals generated when the mechanical watch is running is the same. If the disc pin 41 on the balance wheel 4 is not in the equilibrium position when the balance wheel 4 is stationary, the time interval between adjacent chime signals generated near the equilibrium position during the operation of the mechanical watch will be different, resulting in a polarization phenomenon. Therefore, the polarization value of the mechanical watch can be determined by identifying the time interval between identical striking sounds in adjacent chime signals generated within one cycle. (See also...) Figure 3 The oscillation time t and rotation angle of the escapement mechanism theory The relationship between them can be expressed as: Figure 3 The simple harmonic motion curve is used to represent the oscillation, where the amplitude (i.e., the swing amplitude) is A, and the period is T. Within one period T, the theoretical two half periods are X = T / 2 and Y = T / 2, respectively. If the disc pin 41 on the balance wheel 4 is not in the equilibrium position when the balance wheel 4 is at rest, the time interval between adjacent tone signals is different, namely X′ = T / 2 + t. 偏 Y′=T / 2-t 偏 , where t 偏 The value is the polarization value, and t 偏 =|X′-Y′| / 2, in milliseconds.

[0042] Please see Figure 4 , Figure 4 This is a flowchart illustrating a polarization correction method for a mechanical watch according to an embodiment of the present invention. The polarization correction method for a mechanical watch according to an embodiment of the present invention includes steps S101 to S108.

[0043] S101. Control the sound sensor to contact the mechanical watch to obtain a set of watch sound signals, and control the image acquisition module to acquire an image of the balance wheel 4 of the mechanical watch based on the system time of the first watch sound signal in the set of watch sound signals to obtain a set of balance wheel images.

[0044] In this embodiment, when performing polarization correction on the mechanical watch, a sound sensor is brought into contact with the watch to collect multiple watch tone signals generated by the watch, thus obtaining a set of watch tone signals. The sound sensor can be a microphone, fiber optic sound sensor, etc., and can effectively contact any identifiable part of the mechanical watch (such as the watch case, crown, watch glass, etc.). Simultaneously, when the system time corresponding to the first watch tone signal in the set is determined by the sound sensor, the image acquisition module is controlled to acquire an image of the balance wheel 4 of the mechanical watch at that moment, thus obtaining a balance wheel image set.

[0045] In one embodiment, step S101 includes:

[0046] The sound sensor is controlled to contact the mechanical watch to collect multiple watch tone signals in a time sequence and form the watch tone signal set;

[0047] The image acquisition module is controlled to acquire multiple balance wheel images of the balance wheel 4 in sequence according to the system time of the first sound signal acquired in the sound signal set, and form the balance wheel image set.

[0048] In this embodiment, the watch tone signal set includes multiple watch tone signals generated by the mechanical watch, which are sequentially acquired by the sound sensor in a time sequence. The sound sensor is controlled to contact the mechanical watch and acquire multiple watch tone signals sequentially in a time sequence, forming the watch tone signal set. Simultaneously, the balance wheel image set includes multiple balance wheel images sequentially acquired by the image acquisition module at the system time acquired by the first watch tone signal in the watch tone signal set. That is, at the system time acquired by the first watch tone signal in the watch tone signal set, the image acquisition module will acquire images of the balance wheel 4 of the mechanical watch, obtaining multiple balance wheel images acquired sequentially in a time sequence, forming the balance wheel image set.

[0049] S102. Obtain the system time corresponding to each tone signal in the tone signal set collected by the sound sensor, which constitutes a time parameter set.

[0050] In this embodiment, the system time is used as a reference to record the system time corresponding to the time when the sound sensor collects the watch tone signal of the mechanical watch. A time parameter set is formed by obtaining the system time corresponding to each watch tone signal in the set of watch tone signals collected by the sound sensor, so as to obtain the time interval between adjacent watch tone signals.

[0051] S103. Obtain polarization data based on the set of tone signals, and identify the balance wheel direction corresponding to the first tone signal in the set of tone signals based on the balance wheel image set.

[0052] In this embodiment, polarization data can be obtained from the watch tone signal set, including the period, amplitude, and polarization value. Simultaneously, by performing image recognition on the balance wheel image set, the balance wheel direction corresponding to the first watch tone signal in the set can be identified. The balance wheel direction is the rotation direction of the balance wheel 4 when the mechanical watch generates the first watch tone signal. This allows the polarization direction to be obtained subsequently using the time parameter set and the balance wheel direction, thereby quickly determining the direction in which the disc pin 41 needs to be adjusted.

[0053] In one embodiment, identifying the balance wheel direction corresponding to the first tone signal in the tone signal set based on the balance wheel image set includes:

[0054] The positions of preset feature points in each balance wheel image in the balance wheel image set are identified sequentially to obtain feature point position data;

[0055] The direction of the balance wheel is obtained based on the location data of the feature points.

[0056] In this embodiment, the balance wheel image set includes multiple balance wheel images acquired sequentially by the image acquisition module based on the system time of the first sound signal in the sound signal set. The positions of preset feature points in each balance wheel image are identified sequentially to obtain feature point position data. The feature point position data indicates the direction of position change of the preset feature points during the rotation of the mechanical watch. The direction of rotation of the preset feature points can be determined by the direction of position change of the preset feature points, thereby determining the rotation direction of the balance wheel 4. Therefore, the balance wheel direction can be obtained through the feature point position data. The preset feature points can be the balance beam, weights, screws, or other non-circular structures on the balance wheel 4.

[0057] S104. Obtain the polarization direction based on the time parameter set and the balance wheel direction.

[0058] In this embodiment, the time interval between adjacent tone signals can be obtained through the time parameter set, thereby determining the duration occupied by two tone signals generated sequentially in one cycle. Furthermore, the rotation direction of the balance wheel 4 corresponding to each of the remaining tone signals in the tone signal set can be obtained based on the balance wheel direction. The polarization direction is the direction in which the center line of the disc pin 41 on the balance wheel 4 deviates from the line 6 connecting the balance wheel 4 and the escapement fork axis. If the duration occupied by the tone signal generated first in one cycle is greater than the duration occupied by the tone signal generated later, it means that the direction in which the center line of the disc pin 41 deviates from the line 6 connecting the balance wheel 4 and the escapement fork axis is the rotation direction of the balance wheel 4 corresponding to the tone signal generated first in that cycle. Therefore, the rotation direction of the balance wheel 4 corresponding to the tone signal generated first in that cycle is taken as the polarization direction. If the duration of the first tone signal in a cycle is less than the duration of the second tone signal, it means that the direction of the center line of the disc pin 41 deviating from the center line 6 connecting the balance wheel 4 and the escapement fork axis is the opposite direction of the rotation direction of the balance wheel 4 corresponding to the first tone signal in that cycle. Therefore, the opposite direction of the rotation direction of the balance wheel 4 corresponding to the first tone signal in that cycle is taken as the polarization direction.

[0059] In one embodiment, step S104 includes:

[0060] The system time corresponding to the i-th tone signal in the tone signal set is obtained as the i-th time parameter, the system time corresponding to the (i+1)-th tone signal in the tone signal set is obtained as the (i+1)-th time parameter, and the system time corresponding to the (i+2)-th tone signal in the tone signal set is obtained as the (i+2)-th time parameter; where i ≤ (n-2), and n is the number of tone signals included in the tone signal set;

[0061] The first duration is obtained based on the difference between the (i+1)th time parameter and the ith time parameter, and the second duration is obtained based on the difference between the (i+2)th time parameter and the (i+1)th time parameter.

[0062] The direction of the i-th balance wheel corresponding to the i-th tone signal in the tone signal set is obtained based on the direction of the balance wheel.

[0063] If it is determined that the first duration is greater than the second duration, then the direction of the i-th balance wheel is taken as the polarization direction;

[0064] If it is determined that the first duration is less than the second duration, then the polarization direction is taken as the opposite direction of the i-th balance wheel.

[0065] In this embodiment, the rotation direction of the balance wheel 4 corresponding to each of the remaining tone signals in the tone signal set can be obtained according to the direction of the balance wheel. (Refer to...) Figure 3The tone signal corresponding to curve E is the first tone signal in the tone signal set (i.e., the 1st tone signal), the tone signal corresponding to curve F is the 2nd tone signal in the tone signal set, and the tone signal corresponding to curve G is the 3rd tone signal in the tone signal set. If the direction of the balance wheel corresponding to the 1st tone signal is clockwise, then it can be determined that when the 2nd tone signal is generated at curve F, the balance wheel 4 rotates counterclockwise, and the rotation direction of the balance wheel 4 corresponding to the 2nd tone signal (i.e., the 2nd balance wheel direction) is counterclockwise. Similarly, it can be determined that when the 3rd tone signal is generated at curve G, the balance wheel 4 rotates clockwise, and the rotation direction of the balance wheel 4 corresponding to the 3rd tone signal (i.e., the 3rd balance wheel direction) is clockwise, and so on. Furthermore, if the balance wheel direction corresponding to the first tone signal is counterclockwise, then it can be determined that when the second tone signal is generated at curve F, balance wheel 4 rotates clockwise, and the rotation direction of balance wheel 4 corresponding to the second tone signal (i.e., the second balance wheel direction) is clockwise; similarly, it can be determined that when the third tone signal is generated at curve G, balance wheel 4 rotates counterclockwise, and the rotation direction of balance wheel 4 corresponding to the third tone signal (i.e., the third balance wheel direction) is counterclockwise, and so on. Therefore, if i is odd, then the direction of the i-th balance wheel corresponding to the i-th tone signal in the tone signal set is the balance wheel direction; if i is even, then the direction of the i-th balance wheel corresponding to the i-th tone signal in the tone signal set is the opposite direction of the balance wheel direction. Specifically, the first duration and the second duration represent the durations occupied by two tone signals generated sequentially within one cycle. If the first duration is determined to be greater than the second duration, the direction of the i-th pendulum wheel is used as the polarization direction; if the first duration is determined to be less than the second duration, the opposite direction of the i-th pendulum wheel is used as the polarization direction. For example, the time parameter corresponding to the first tone signal in the tone signal set is obtained as the first time parameter t1, the time parameter corresponding to the second tone signal in the tone signal set is obtained as the second time parameter t2, and the time parameter corresponding to the third tone signal in the tone signal set is obtained as the third time parameter t3; the first duration X' is obtained based on the difference between t2 and t1, and the second duration Y' is obtained based on the difference between t3 and t2; the direction of the first pendulum wheel corresponding to the first tone signal in the tone signal set is the pendulum wheel direction. If X' > Y', the pendulum wheel direction is used as the polarization direction; if X' < Y', the opposite direction of the pendulum wheel direction is used as the polarization direction.

[0066] S105. The rotation angle is calculated based on the polarization data and the preset rotation angle strategy.

[0067] In this embodiment, the rotation angle is calculated using polarization data and a rotation angle strategy to determine the angle that needs to be adjusted later, so that the position of the disc nail 41 can be quickly adjusted according to the polarization direction and rotation angle.

[0068] In one embodiment, the polarization data includes period, swing amplitude, and polarization value, and step S105 includes:

[0069] The rotation angle is calculated based on the period, the swing amplitude, the polarization value, and the rotation angle strategy.

[0070] The formula corresponding to the rotation angle strategy is as follows: δ is the rotation angle, A′ is the swing amplitude, T′ is the period, and t′ is the swing angle. 偏 The polarization value is given.

[0071] In this embodiment, the actual period T′, amplitude A′, and polarization value t′ of the mechanical watch can be obtained from the watch tone signal set. 偏 It consists of the period T′, the swing amplitude A′ and the polarization value t′ 偏 The polarization data is composed of the period T′, amplitude A′, and polarization value t′. 偏 Substitute the formula corresponding to the rotation angle strategy The rotation angle δ can be obtained by calculation.

[0072] S106. Perform image recognition on the mechanical watch to obtain recognition data, and determine the tool type and tool insertion position based on the recognition data, the polarization direction and the preset correction mapping relationship.

[0073] In this embodiment, a pre-set image recognition module can perform image recognition on the mechanical watch to obtain recognition data. This recognition data includes the movement type, adjustment area, and balance wheel rotation center 42. The movement image of the mechanical watch can be obtained and compared with a pre-set set of movement images to identify the movement type. A pre-set target detection model can be used to obtain the adjustment area and balance wheel rotation center 42 of the mechanical watch. (See reference...) Figure 6 The adjustment area of ​​a mechanical watch is generally on both sides of the outer stud arm 8 (e.g., Figure 6 The first region 1 and the second region 2 in the middle). However, sometimes the outer pile cantilever 8 will have a slot (such as Figure 6 The third region 3), where the adjustment area of ​​the mechanical watch is located on both sides of the outer stud arm 8 and in the slot of the outer stud arm 8. Therefore, the adjustment area of ​​the mechanical watch includes a first region 1 and a second region 2, wherein the first region 1 is located on the left side of the outer stud arm 8, and is an area that can accommodate the insertion of the adjustment tool without interfering with other parts; the second region 2 is located on the right side of the outer stud arm 8 and the left side of the regulator arm 5 (i.e., between the outer stud arm 8 and the regulator arm 5), and is an area that can accommodate the insertion of the adjustment tool without interfering with other parts. Optionally, the adjustment area of ​​the mechanical watch may also include a third region 3, which is located in the slot of the outer stud arm 8.

[0074] The adjustment area of ​​a mechanical watch is determined by the outer stud 7 structure. Different movements may have different outer stud 7 structures, resulting in different adjustment areas and thus different types of adjustment tools. Furthermore, different types of adjustment tools have different usage methods. Different types of adjustment tools, when inserted into different adjustment areas, need to be rotated in the corresponding direction to rotate the outer stud 7, which in turn rotates the disc pin 41 on the balance wheel 4 by the corresponding angle. For a pin-shaped adjustment tool, when inserted into the first area 1, it needs to be rotated clockwise; when inserted into the second area 2, it needs to be rotated counterclockwise; when inserted into the third area 3, it can be adjusted in both directions, i.e., rotated clockwise or counterclockwise. For a U-shaped adjustment tool (see...),... Figure 7 The U-shaped adjustment tool is attached to the outer cantilever arm 8, with one side inserted into the first region 1 and the other into the second region 2. This allows for bidirectional adjustment; the U-shaped tool can be rotated clockwise or counterclockwise. Alternatively, a needle-like protrusion can be added between the two sides of the U-shaped tool and inserted into the third region 3, again enabling bidirectional adjustment. Therefore, after obtaining the identification data, it is necessary to determine the appropriate tool type for the mechanical watch, and the insertion position of the adjustment tool based on the identification data, polarization direction, and correction mapping relationship.

[0075] More specifically, the tool type and insertion position are determined based on the identification data, polarization direction, and a preset correction mapping relationship. This includes: determining the tool type based on the movement type in the identification data and the correction mapping relationship; and determining the tool insertion position based on the tool type, adjustment area, polarization direction, and adjustment mapping relationship. The preset correction mapping relationship specifies the applicable tool types for different movement types of mechanical watches. Furthermore, since the polarization direction is the direction in which the center line of the disc pin 41 on the balance wheel 4 deviates from the line 6 connecting the balance wheel 4 and the escapement fork axis, the outer stud 7 needs to rotate in the opposite direction of the polarization direction. Therefore, the adjustment tool needs to rotate in the opposite direction of the polarization direction. Thus, the tool insertion position can be determined based on the tool type, adjustment area, polarization direction, and adjustment mapping relationship. The tool insertion position is the specific location within the adjustment area where the adjustment tool needs to be inserted. This position is determined after considering that the adjustment tool can be accommodated, such as the preset point A position in the first area 1 (e.g., Figure 8Point A in the diagram, the preset point C in the second region 2 (not shown), or the preset point D in the third region 3 (not shown), etc. For example, referring to Table 1, which shows the correction mapping relationship provided in this embodiment, if the movement type of the mechanical watch is determined to be movement 11, then according to the correction mapping relationship, the suitable tool type for the mechanical watch is a needle-shaped adjustment tool. Then, based on the identified adjustment area of ​​the mechanical watch, which includes the first region 1 and the second region 2, and when the polarization direction is counterclockwise, it indicates that the adjustment tool needs to be inserted into the first region 1 to rotate clockwise, thereby causing the outer stud 7 to rotate clockwise. Thus, the preset point A in the first region 1 can be used as the tool insertion position; when the polarization direction is counterclockwise, it indicates that the adjustment tool needs to be inserted into the second region 2 to rotate counterclockwise. Thus, the preset point C in the second region 2 can be used as the tool insertion position.

[0079] S107. Obtain the correction direction based on the opposite direction of the polarization direction.

[0080] In this embodiment, since the polarization direction is the direction in which the center line of the disc pin 41 on the balance wheel 4 deviates from the line 6 connecting the balance wheel 4 and the escapement fork shaft, the outer stud 7 needs to rotate in the opposite direction of the polarization direction to drive the disc pin 41 to rotate, so that the center line of the disc pin 41 coincides with the line 6 connecting the balance wheel 4 and the escapement fork shaft, or so that the disc pin 41 is near the allowable position of the line 6 connecting the balance wheel 4 and the escapement fork shaft, thereby correcting the polarization of the mechanical watch within the allowable range.

[0081] S108. Control the execution device to drive the adjustment tool of the tool type to insert into the tool insertion position, and control the execution device to drive the adjustment tool to rotate around the balance wheel rotation center 42 of the mechanical watch in the correction direction by the rotation angle.

[0082] In this embodiment, the control execution device drives the determined adjustment tool of a specific type to be inserted into the tool insertion position. After confirming that the adjustment tool is inserted into the tool insertion position, the control execution device drives the adjustment tool to rotate around the balance wheel rotation center 42 of the mechanical watch in the correction direction by a corresponding rotation angle. This causes the outer stud 7 to rotate around the balance wheel rotation center 42 by a corresponding angle, thereby driving the disc pin 41 to rotate by a corresponding angle. This ensures that the center line of the disc pin 41 coincides with the center line 6 connecting the balance wheel 4 and the escapement fork axis, or that the disc pin 41 is positioned near the allowable center line 6 connecting the balance wheel 4 and the escapement fork axis, thus achieving the correction of the mechanical watch's polarization. Ideally, the adjustment of the mechanical watch's polarization through steps S101 to S108 is very precise. One adjustment is sufficient to ensure that the polarization value of the mechanical watch meets the tolerance requirements, thus ending the polarization correction process for the mechanical watch. The balance wheel rotation center 42 is identified by image recognition of the mechanical watch, and the identification data includes the balance wheel rotation center 42. The actuating device can be a multi-axis robotic arm, a combination of multiple linear actuators, swing mechanisms, rotation mechanisms, etc., and can be an XY table or an XYZ table, etc. The actuating device is used to drive the adjustment tool to the insertion position and to perform angular or displacement operations on the adjustment tool. In actual operation, the adjustment tool is not necessarily inserted vertically perpendicular to the mechanism's assembly surface into the insertion position, as this may cause the adjustment tool to collide with the outer cantilever arm 8 due to accuracy issues, resulting in damage to the mechanism. Preferably, the actuating device can be controlled to move the adjustment tool into an adjustment area corresponding to the insertion position where it does not contact other parts, and after the adjustment tool reaches the set depth, the actuating device can be controlled to move the adjustment tool translatably to the insertion position. Optionally, the insertion depth of the adjustment tool can be determined by image recognition, laser recognition, etc.

[0083] More specifically, in one embodiment, controlling the execution device to drive the adjustment tool to rotate by the rotation angle around the balance wheel rotation center 42 of the mechanical watch in the correction direction includes:

[0084] The radius of rotation is determined based on the tool insertion position and the rotation center 42 of the pendulum wheel.

[0085] The circular arc path is obtained based on the rotation radius, the rotation angle, the preset arc length calculation strategy, the tool insertion position, and the correction direction, and the execution device is controlled to drive the adjustment tool to move along the circular arc path.

[0086] Alternatively, a straight path can be obtained based on the rotation radius, the rotation angle, a preset straight distance strategy, the tool insertion position, and the correction direction, and the execution device can be controlled to drive the adjustment tool to move along the straight path.

[0087] In this embodiment, refer to Figure 8 According to the tool insertion position (e.g. Figure 8 The line connecting point A (shown in the diagram) and the center of rotation 42 of the pendulum wheel can determine a rotation radius. Based on this radius, the actual starting angle of rotation can be obtained, and the adjusting tool can be rotated by the corresponding angle. Since the adjusting tool touches the outer pile cantilever 8 when inserted into its insertion position, rotating the adjusting tool will cause the outer pile 7 to rotate. Optionally, a function to identify when the adjusting tool touches the outer pile cantilever 8 can be provided. This identification can be based on pressure (pressure sensors on the adjusting tool or its connecting structure), electrical (e.g., a circuit is created when the adjusting tool contacts the outer pile cantilever 8), or magnetic properties. This function detects whether the actual insertion position of the adjusting tool is the correct insertion position, ensuring that the rotation radius is the actual radius determined by the line connecting the actual insertion position of the adjusting tool and the center of rotation 42 of the pendulum wheel. Specifically, the actuator can be controlled to drive the adjustment tool in an arc motion to rotate around the pendulum's rotation center 42 by a corresponding rotation angle. The arc length is determined based on the rotation radius, rotation angle, and arc length calculation strategy. The formula for the arc length calculation strategy is L = δπr / 180, where L is the arc length, δ is the rotation angle, and r is the rotation radius. The arc path is obtained based on the arc length, tool insertion position, and correction direction. Controlling the actuator to drive the adjustment tool in a circular motion along the arc path allows the adjustment tool to rotate δ around the pendulum's rotation center 42 in the correction direction. Alternatively, since the rotation angle is very small, the actuator can also be controlled to drive the adjustment tool in a straight line to rotate around the pendulum's rotation center 42 by a corresponding rotation angle. The straight-line movement distance is determined based on the rotation radius, rotation angle, and straight-line distance strategy. The formula for the straight-line distance strategy is L. AB =2rsin(δ / 2), L AB δ is the linear movement distance, δ is the rotation angle, and r is the rotation radius. The straight path is obtained based on the linear movement distance, tool insertion position, and correction direction. (See [reference]). Figure 8 The straight path is The direction is from A to B, and the control actuator drives the adjustment tool along a straight path. If the adjustment tool is moved from A to B, the adjustment tool can rotate around the center of rotation of the pendulum wheel by an angle δ in the correction direction.

[0088] In one embodiment, see Figure 5 After step S108, the method further includes:

[0089] S109. Obtain the current tone signal set of the mechanical watch, and obtain the current polarization data based on the current tone signal set;

[0090] S110. If the polarization value of the mechanical watch is determined to be less than the preset polarization tolerance value based on the current polarization data, the calibration process is terminated.

[0091] In this embodiment, considering issues such as device accuracy, the polarization value of the mechanical watch may not meet the tolerance requirements after polarization correction. Therefore, after step S108, it is necessary to obtain the current tone signal set of the mechanical watch to obtain the current polarization data, i.e., the polarization data after polarization correction. The current polarization data includes the polarization value of the mechanical watch after polarization correction. By comparing the polarization value in the current polarization data with the preset polarization tolerance value, it is detected whether the polarization of the corrected mechanical watch meets the tolerance requirements. If it is determined from the current polarization data that the polarization value of the mechanical watch is less than the polarization tolerance value, it indicates that the polarization of the corrected mechanical watch meets the tolerance requirements, and the polarization correction process for the mechanical watch can be terminated.

[0092] In one embodiment, see Figure 5 After step S109, the method further includes:

[0093] S111. If the polarization value of the mechanical watch is determined to be greater than the polarization tolerance value based on the current polarization data, then the current balance wheel image set obtained by the image acquisition module for image acquisition of the balance wheel 4 at the system time of the first current watch tone signal in the current watch tone signal set is obtained, and the current balance wheel direction corresponding to the first current watch tone signal in the current watch tone signal set is identified based on the current balance wheel image set.

[0094] S112. Obtain the system time corresponding to each current tone signal in the current tone signal set to form a current time parameter set;

[0095] S113. Update the polarization data with the current polarization data, update the time parameter set with the current time parameter set, update the balance wheel direction with the current balance wheel direction, and return to execute step S104.

[0096] In this embodiment, if the polarization value of the mechanical watch is determined to be greater than the polarization tolerance value based on the current polarization data, it indicates that the polarization of the corrected mechanical watch still does not meet the tolerance requirements, and the polarization of the mechanical watch needs to be recalibrated. When the sound sensor acquires the system time corresponding to the first current tone signal in the current tone signal set, the image acquisition module immediately acquires an image of the balance wheel 4 to obtain the current balance wheel image set. Therefore, after determining that the polarization value of the mechanical watch is greater than the polarization tolerance value, the current balance wheel image set is acquired to identify the current balance wheel direction corresponding to the first current tone signal in the current tone signal set. Furthermore, the current time parameter set is acquired, the polarization data is updated with the current polarization data, the time parameter set is updated with the current time parameter set, and the balance wheel direction is updated with the current balance wheel direction. The process then returns to step S104, thereby recalibrating the polarization of the corrected mechanical watch to ensure that the polarization of the mechanical watch meets the tolerance requirements. This improves the accuracy of the polarization correction and the precision of the mechanical watch's polarization.

[0097] The present invention discloses a polarization correction method for mechanical watches. Based on polarization data and the balance wheel direction, it can quickly determine the angle and direction of rotation of the adjustment tool, and then quickly adjust the position of the disc pin 41, so that the polarization of the mechanical watch meets the tolerance requirements, and can achieve rapid and quantitative correction of the polarization of the mechanical watch.

[0098] This invention also provides a polarization correction device for mechanical watches, which is used to perform any of the aforementioned polarization correction methods for mechanical watches. Specifically, please refer to... Figure 9 , Figure 9 This is a schematic block diagram of a mechanical watch polarization correction device provided in an embodiment of the present invention. The mechanical watch polarization correction device 100 provided in this embodiment of the present invention includes a data acquisition unit 101, a time parameter acquisition unit 102, a data direction acquisition unit 103, a polarization direction acquisition unit 104, a rotation angle acquisition unit 105, a tool data acquisition unit 106, a correction direction acquisition unit 107, and a polarization correction unit 108.

[0099] The acquisition unit 101 is used to control the sound sensor to contact the mechanical watch to obtain a set of watch sound signals, and to control the image acquisition module to acquire an image of the balance wheel 4 of the mechanical watch at the system time of the first watch sound signal in the set of watch sound signals to obtain a set of balance wheel images.

[0100] In this embodiment, when performing polarization correction on the mechanical watch, a sound sensor is brought into contact with the watch to collect multiple watch tone signals generated by the watch, thus obtaining a set of watch tone signals. The sound sensor can be a microphone, fiber optic sound sensor, etc., and can effectively contact any identifiable part of the mechanical watch (such as the watch case, crown, watch glass, etc.). Simultaneously, when the system time corresponding to the first watch tone signal in the set is determined by the sound sensor, the image acquisition module is controlled to acquire an image of the balance wheel 4 of the mechanical watch at that moment, thus obtaining a balance wheel image set.

[0101] In one embodiment, the acquisition unit 101 is specifically used for:

[0102] The sound sensor is controlled to contact the mechanical watch to collect multiple watch tone signals in a time sequence and form the watch tone signal set;

[0103] The image acquisition module is controlled to acquire multiple balance wheel images of the balance wheel 4 in sequence according to the system time of the first sound signal acquired in the sound signal set, and form the balance wheel image set.

[0104] In this embodiment, the watch tone signal set includes multiple watch tone signals generated by the mechanical watch, which are sequentially acquired by the sound sensor in a time sequence. The sound sensor is controlled to contact the mechanical watch and acquire multiple watch tone signals sequentially in a time sequence, forming the watch tone signal set. Simultaneously, the balance wheel image set includes multiple balance wheel images sequentially acquired by the image acquisition module at the system time acquired by the first watch tone signal in the watch tone signal set. That is, at the system time acquired by the first watch tone signal in the watch tone signal set, the image acquisition module will acquire images of the balance wheel 4 of the mechanical watch, obtaining multiple balance wheel images acquired sequentially in a time sequence, forming the balance wheel image set.

[0105] The time parameter acquisition unit 102 is used to acquire the system time corresponding to each tone signal in the tone signal set collected by the sound sensor, which constitutes a time parameter set.

[0106] In this embodiment, the system time is used as a reference to record the system time corresponding to the time when the sound sensor collects the watch tone signal of the mechanical watch. A time parameter set is formed by obtaining the system time corresponding to each watch tone signal in the set of watch tone signals collected by the sound sensor, so as to obtain the time interval between adjacent watch tone signals.

[0107] The data direction acquisition unit 103 is used to obtain polarization data based on the tone signal set and identify the balance wheel direction corresponding to the first tone signal in the tone signal set based on the balance wheel image set.

[0108] In this embodiment, polarization data can be obtained from the watch tone signal set, including the period, amplitude, and polarization value. Simultaneously, by performing image recognition on the balance wheel image set, the balance wheel direction corresponding to the first watch tone signal in the set can be identified. The balance wheel direction is the rotation direction of the balance wheel 4 when the mechanical watch generates the first watch tone signal. This allows the polarization direction to be obtained subsequently using the time parameter set and the balance wheel direction, thereby quickly determining the direction in which the disc pin 41 needs to be adjusted.

[0109] In one embodiment, when the data direction acquisition unit 103 performs the step of identifying the balance wheel direction corresponding to the first tone signal in the tone signal set based on the balance wheel image set, it is specifically used for:

[0110] The positions of preset feature points in each balance wheel image in the balance wheel image set are identified sequentially to obtain feature point position data;

[0111] The direction of the balance wheel is obtained based on the location data of the feature points.

[0112] In this embodiment, the balance wheel image set includes multiple balance wheel images acquired sequentially by the image acquisition module based on the system time of the first sound signal in the sound signal set. The positions of preset feature points in each balance wheel image are identified sequentially to obtain feature point position data. The feature point position data indicates the direction of position change of the preset feature points during the rotation of the mechanical watch. The direction of rotation of the preset feature points can be determined by the direction of position change of the preset feature points, thereby determining the rotation direction of the balance wheel 4. Therefore, the balance wheel direction can be obtained through the feature point position data. The preset feature points can be the balance beam, weights, screws, or other non-circular structures on the balance wheel 4.

[0113] The polarization direction acquisition unit 104 is used to obtain the polarization direction based on the time parameter set and the balance wheel direction.

[0114] In this embodiment, the time interval between adjacent tone signals can be obtained through the time parameter set, thereby determining the duration occupied by two tone signals generated sequentially in one cycle. Furthermore, the rotation direction of the balance wheel 4 corresponding to each of the remaining tone signals in the tone signal set can be obtained based on the balance wheel direction. The polarization direction is the direction in which the center line of the disc pin 41 on the balance wheel 4 deviates from the line 6 connecting the balance wheel 4 and the escapement fork axis. If the duration occupied by the tone signal generated first in one cycle is greater than the duration occupied by the tone signal generated later, it means that the direction in which the center line of the disc pin 41 deviates from the line 6 connecting the balance wheel 4 and the escapement fork axis is the rotation direction of the balance wheel 4 corresponding to the tone signal generated first in that cycle. Therefore, the rotation direction of the balance wheel 4 corresponding to the tone signal generated first in that cycle is taken as the polarization direction. If the duration of the first tone signal in a cycle is less than the duration of the second tone signal, it means that the direction of the center line of the disc pin 41 deviating from the center line 6 connecting the balance wheel 4 and the escapement fork axis is the opposite direction of the rotation direction of the balance wheel 4 corresponding to the first tone signal in that cycle. Therefore, the opposite direction of the rotation direction of the balance wheel 4 corresponding to the first tone signal in that cycle is taken as the polarization direction.

[0115] In one embodiment, the polarization direction acquisition unit 104 is specifically used for:

[0116] The system time corresponding to the i-th tone signal in the tone signal set is obtained as the i-th time parameter, the system time corresponding to the (i+1)-th tone signal in the tone signal set is obtained as the (i+1)-th time parameter, and the system time corresponding to the (i+2)-th tone signal in the tone signal set is obtained as the (i+2)-th time parameter; where i ≤ (n-2), and n is the number of tone signals included in the tone signal set;

[0117] The first duration is obtained based on the difference between the (i+1)th time parameter and the ith time parameter, and the second duration is obtained based on the difference between the (i+2)th time parameter and the (i+1)th time parameter.

[0118] The direction of the i-th balance wheel corresponding to the i-th tone signal in the tone signal set is obtained based on the direction of the balance wheel.

[0119] If it is determined that the first duration is greater than the second duration, then the direction of the i-th balance wheel is taken as the polarization direction;

[0120] If it is determined that the first duration is less than the second duration, then the polarization direction is taken as the opposite direction of the i-th balance wheel.

[0121] In this embodiment, the rotation direction of the balance wheel 4 corresponding to each of the remaining tone signals in the tone signal set can be obtained according to the direction of the balance wheel. (Refer to...) Figure 3The tone signal corresponding to curve E is the first tone signal in the tone signal set (i.e., the 1st tone signal), the tone signal corresponding to curve F is the 2nd tone signal in the tone signal set, and the tone signal corresponding to curve G is the 3rd tone signal in the tone signal set. If the direction of the balance wheel corresponding to the 1st tone signal is clockwise, then it can be determined that when the 2nd tone signal is generated at curve F, the balance wheel 4 rotates counterclockwise, and the rotation direction of the balance wheel 4 corresponding to the 2nd tone signal (i.e., the 2nd balance wheel direction) is counterclockwise. Similarly, it can be determined that when the 3rd tone signal is generated at curve G, the balance wheel 4 rotates clockwise, and the rotation direction of the balance wheel 4 corresponding to the 3rd tone signal (i.e., the 3rd balance wheel direction) is clockwise, and so on. Furthermore, if the balance wheel direction corresponding to the first tone signal is counterclockwise, then it can be determined that when the second tone signal is generated at curve F, balance wheel 4 rotates clockwise, and the rotation direction of balance wheel 4 corresponding to the second tone signal (i.e., the second balance wheel direction) is clockwise; similarly, it can be determined that when the third tone signal is generated at curve G, balance wheel 4 rotates counterclockwise, and the rotation direction of balance wheel 4 corresponding to the third tone signal (i.e., the third balance wheel direction) is counterclockwise, and so on. Therefore, if i is odd, then the direction of the i-th balance wheel corresponding to the i-th tone signal in the tone signal set is the balance wheel direction; if i is even, then the direction of the i-th balance wheel corresponding to the i-th tone signal in the tone signal set is the opposite direction of the balance wheel direction. Specifically, the first duration and the second duration represent the durations occupied by two tone signals generated sequentially within one cycle. If the first duration is determined to be greater than the second duration, the direction of the i-th pendulum wheel is used as the polarization direction; if the first duration is determined to be less than the second duration, the opposite direction of the i-th pendulum wheel is used as the polarization direction. For example, the time parameter corresponding to the first tone signal in the tone signal set is obtained as the first time parameter t1, the time parameter corresponding to the second tone signal in the tone signal set is obtained as the second time parameter t2, and the time parameter corresponding to the third tone signal in the tone signal set is obtained as the third time parameter t3; the first duration X' is obtained based on the difference between t2 and t1, and the second duration Y' is obtained based on the difference between t3 and t2; the direction of the first pendulum wheel corresponding to the first tone signal in the tone signal set is the pendulum wheel direction. If X' > Y', the pendulum wheel direction is used as the polarization direction; if X' < Y', the opposite direction of the pendulum wheel direction is used as the polarization direction.

[0122] The rotation angle acquisition unit 105 is used to calculate the rotation angle based on the polarization data and the preset rotation angle strategy.

[0123] In this embodiment, the rotation angle is calculated using polarization data and a rotation angle strategy to determine the angle that needs to be adjusted later, so that the position of the disc nail 41 can be quickly adjusted according to the polarization direction and rotation angle.

[0124] In one embodiment, the polarization data includes period, swing amplitude, and polarization value, and the rotation angle acquisition unit 105 is specifically used for:

[0125] The rotation angle is calculated based on the period, the swing amplitude, the polarization value, and the rotation angle strategy.

[0126] The formula corresponding to the rotation angle strategy is as follows: δ is the rotation angle, A′ is the swing amplitude, T′ is the period, and t′ is the swing angle. 偏 The polarization value is given.

[0127] In this embodiment, the actual period T′, amplitude A′, and polarization value t′ of the mechanical watch can be obtained from the watch tone signal set. 偏 It consists of the period T′, the swing amplitude A′ and the polarization value t′ 偏 The polarization data is composed of the period T′, amplitude A′, and polarization value t′. 偏 Substitute the formula corresponding to the rotation angle strategy The rotation angle δ can be obtained by calculation.

[0128] The tool data acquisition unit 106 is used to perform image recognition on the mechanical watch to obtain recognition data, and to determine the tool type and tool insertion position based on the recognition data, the polarization direction and the preset correction mapping relationship.

[0129] In this embodiment, a pre-set image recognition module can perform image recognition on the mechanical watch to obtain recognition data. This recognition data includes the movement type, adjustment area, and balance wheel rotation center 42. The movement image of the mechanical watch can be obtained and compared with a pre-set set of movement images to identify the movement type. A pre-set target detection model can be used to obtain the adjustment area and balance wheel rotation center 42 of the mechanical watch. (See reference...) Figure 6 The adjustment area of ​​a mechanical watch is generally on both sides of the outer stud arm 8 (e.g., Figure 6 The first region 1 and the second region 2 in the middle). However, sometimes the outer pile cantilever 8 will have a slot (such as Figure 6 The third region 3), where the adjustment area of ​​the mechanical watch is located on both sides of the outer stud arm 8 and in the slot of the outer stud arm 8. Therefore, the adjustment area of ​​the mechanical watch includes a first region 1 and a second region 2, wherein the first region 1 is located on the left side of the outer stud arm 8, and is an area that can accommodate the insertion of the adjustment tool without interfering with other parts; the second region 2 is located on the right side of the outer stud arm 8 and the left side of the regulator arm 5 (i.e., between the outer stud arm 8 and the regulator arm 5), and is an area that can accommodate the insertion of the adjustment tool without interfering with other parts. Optionally, the adjustment area of ​​the mechanical watch may also include a third region 3, which is located in the slot of the outer stud arm 8.

[0130] The adjustment area of ​​a mechanical watch is determined by the outer stud 7 structure. Different movements may have different outer stud 7 structures, resulting in different adjustment areas and thus different types of adjustment tools. Furthermore, different types of adjustment tools have different usage methods. Different types of adjustment tools, when inserted into different adjustment areas, need to be rotated in the corresponding direction to rotate the outer stud 7, which in turn rotates the disc pin 41 on the balance wheel 4 by the corresponding angle. For a pin-shaped adjustment tool, when inserted into the first area 1, it needs to be rotated clockwise; when inserted into the second area 2, it needs to be rotated counterclockwise; when inserted into the third area 3, it can be adjusted in both directions, i.e., rotated clockwise or counterclockwise. For a U-shaped adjustment tool (see...),... Figure 7 The U-shaped adjustment tool is attached to the outer cantilever arm 8, with one side inserted into the first region 1 and the other into the second region 2. This allows for bidirectional adjustment; the U-shaped tool can be rotated clockwise or counterclockwise. Alternatively, a needle-like protrusion can be added between the two sides of the U-shaped tool and inserted into the third region 3, again enabling bidirectional adjustment. Therefore, after obtaining the identification data, it is necessary to determine the appropriate tool type for the mechanical watch, and the insertion position of the adjustment tool based on the identification data, polarization direction, and correction mapping relationship.

[0131] More specifically, the tool type and insertion position are determined based on the identification data, polarization direction, and a preset correction mapping relationship. This includes: determining the tool type based on the movement type in the identification data and the correction mapping relationship; and determining the tool insertion position based on the tool type, adjustment area, polarization direction, and adjustment mapping relationship. The preset correction mapping relationship specifies the applicable tool types for different movement types of mechanical watches. Furthermore, since the polarization direction is the direction in which the center line of the disc pin 41 on the balance wheel 4 deviates from the line 6 connecting the balance wheel 4 and the escapement fork axis, the outer stud 7 needs to rotate in the opposite direction of the polarization direction. Therefore, the adjustment tool needs to rotate in the opposite direction of the polarization direction. Thus, the tool insertion position can be determined based on the tool type, adjustment area, polarization direction, and adjustment mapping relationship. The tool insertion position is the specific location within the adjustment area where the adjustment tool needs to be inserted. This position is determined after considering that the adjustment tool can be accommodated, such as the preset point A position in the first area 1 (e.g., Figure 8Point A in the diagram, the preset point C in the second region 2 (not shown), or the preset point D in the third region 3 (not shown), etc. For example, referring to Table 1 above, if the movement type of the mechanical watch is determined to be movement 11, then according to the correction mapping relationship, the suitable tool type for this mechanical watch can be determined to be a needle-shaped adjustment tool. Then, based on the identified adjustment areas of the mechanical watch, including the first region 1 and the second region 2, and when the polarization direction is counterclockwise, it indicates that the adjustment tool needs to be inserted into the first region 1 to rotate clockwise, thereby causing the outer stud 7 to rotate clockwise. Thus, the preset point A in the first region 1 can be used as the tool insertion position; when the polarization direction is counterclockwise, it indicates that the adjustment tool needs to be inserted into the second region 2 to rotate counterclockwise. Thus, the preset point C in the second region 2 can be used as the tool insertion position.

[0132] The correction direction acquisition unit 107 is used to obtain the correction direction based on the opposite direction of the polarization direction.

[0133] In this embodiment, since the polarization direction is the direction in which the center line of the disc pin 41 on the balance wheel 4 deviates from the line 6 connecting the balance wheel 4 and the escapement fork shaft, the outer stud 7 needs to rotate in the opposite direction of the polarization direction to drive the disc pin 41 to rotate, so that the center line of the disc pin 41 coincides with the line 6 connecting the balance wheel 4 and the escapement fork shaft, or so that the disc pin 41 is near the allowable position of the line 6 connecting the balance wheel 4 and the escapement fork shaft, thereby correcting the polarization of the mechanical watch within the allowable range.

[0134] The polarization correction unit 108 is used to control the execution device to drive the adjustment tool of the tool type to be inserted into the tool insertion position, and to control the execution device to drive the adjustment tool to rotate around the balance wheel rotation center 42 of the mechanical watch in the correction direction by the rotation angle.

[0135] In this embodiment, the control execution device drives the determined adjustment tool of a specific type to be inserted into the tool insertion position. After confirming that the adjustment tool is inserted into the tool insertion position, the control execution device drives the adjustment tool to rotate around the balance wheel rotation center 42 of the mechanical watch in the correction direction by a corresponding rotation angle. This causes the adjustment tool to push the outer stud 7 to rotate around the balance wheel rotation center 42 by a corresponding angle, thereby causing the disc pin 41 to rotate by a corresponding angle. This ensures that the center line of the disc pin 41 coincides with the center line 6 connecting the balance wheel 4 and the escapement fork axis, or that the disc pin 41 is positioned near the allowable center line 6 connecting the balance wheel 4 and the escapement fork axis, thus correcting the polarization of the mechanical watch. Ideally, performing a single correction process can precisely adjust the polarization of the mechanical watch, ensuring that the polarization value of the mechanical watch meets the tolerance requirements, thereby ending the polarization correction process. The balance wheel rotation center 42 is identified through image recognition of the mechanical watch, and the identification data includes the balance wheel rotation center 42. The actuating device can be a multi-axis robotic arm, a combination of multiple linear actuators, swing mechanisms, rotation mechanisms, etc., and can be an XY table or an XYZ table, etc. The actuating device is used to drive the adjustment tool to the insertion position and to perform angular or displacement operations on the adjustment tool. In actual operation, the adjustment tool is not necessarily inserted vertically perpendicular to the mechanism's assembly surface into the insertion position, as this may cause the adjustment tool to collide with the outer cantilever arm 8 due to accuracy issues, resulting in damage to the mechanism. Preferably, the actuating device can be controlled to move the adjustment tool into an adjustment area corresponding to the insertion position where it does not contact other parts, and after the adjustment tool reaches the set depth, the actuating device can be controlled to move the adjustment tool translatably to the insertion position. Optionally, the insertion depth of the adjustment tool can be determined by image recognition, laser recognition, etc.

[0136] More specifically, in one embodiment, when the polarization correction unit 108 is used to perform the step of controlling the execution device to drive the adjustment tool to rotate around the balance wheel rotation center 42 of the mechanical watch in the correction direction by the rotation angle, it is specifically used for:

[0137] The radius of rotation is determined based on the tool insertion position and the rotation center 42 of the pendulum wheel.

[0138] The circular arc path is obtained based on the rotation radius, the rotation angle, the preset arc length calculation strategy, the tool insertion position, and the correction direction, and the execution device is controlled to drive the adjustment tool to move along the circular arc path.

[0139] Alternatively, a straight path can be obtained based on the rotation radius, the rotation angle, a preset straight distance strategy, the tool insertion position, and the correction direction, and the execution device can be controlled to drive the adjustment tool to move along the straight path.

[0140] In this embodiment, refer to Figure 8 According to the tool insertion position (e.g. Figure 8 The line connecting point A (shown in the diagram) and the center of rotation 42 of the pendulum wheel can determine a rotation radius. Based on this radius, the actual starting angle of rotation can be obtained, and the adjusting tool can be rotated by the corresponding angle. Since the adjusting tool touches the outer pile cantilever 8 when inserted into its insertion position, rotating the adjusting tool will cause the outer pile 7 to rotate. Optionally, a function to identify when the adjusting tool touches the outer pile cantilever 8 can be provided. This identification can be based on pressure (pressure sensors on the adjusting tool or its connecting structure), electrical (e.g., a circuit is created when the adjusting tool contacts the outer pile cantilever 8), or magnetic properties. This function detects whether the actual insertion position of the adjusting tool is the correct insertion position, ensuring that the rotation radius is the actual radius determined by the line connecting the actual insertion position of the adjusting tool and the center of rotation 42 of the pendulum wheel. Specifically, the actuator can be controlled to drive the adjustment tool in an arc motion to rotate around the pendulum's rotation center 42 by a corresponding rotation angle. The arc length is determined based on the rotation radius, rotation angle, and arc length calculation strategy. The formula for the arc length calculation strategy is L = δπr / 180, where L is the arc length, δ is the rotation angle, and r is the rotation radius. The arc path is obtained based on the arc length, tool insertion position, and correction direction. Controlling the actuator to drive the adjustment tool in a circular motion along the arc path allows the adjustment tool to rotate δ around the pendulum's rotation center 42 in the correction direction. Alternatively, since the rotation angle is very small, the actuator can also be controlled to drive the adjustment tool in a straight line to rotate around the pendulum's rotation center 42 by a corresponding rotation angle. The straight-line movement distance is determined based on the rotation radius, rotation angle, and straight-line distance strategy. The formula for the straight-line distance strategy is L. AB =2rsin(δ / 2), L AB δ is the linear movement distance, δ is the rotation angle, and r is the rotation radius. The straight path is obtained based on the linear movement distance, tool insertion position, and correction direction. (See [reference]). Figure 8 The straight path is The direction is from A to B, and the control actuator drives the adjustment tool along a straight path. If the adjustment tool is moved from A to B, the adjustment tool can rotate around the center of rotation of the pendulum wheel by an angle δ in the correction direction.

[0141] In one embodiment, the mechanical watch polarization correction device 100 further includes a polarization detection unit, specifically used for:

[0142] Obtain the current tone signal set of the mechanical watch, and obtain the current polarization data based on the current tone signal set;

[0143] If the polarization value of the mechanical watch is determined to be less than the preset polarization tolerance value based on the current polarization data, the calibration process is terminated.

[0144] In this embodiment, considering issues such as device accuracy, the polarization value of the mechanical watch may not meet the tolerance requirements after polarization correction. Therefore, it is necessary to obtain the current tone signal set of the mechanical watch to obtain the current polarization data, i.e., the polarization data after polarization correction. The current polarization data includes the polarization value of the mechanical watch after polarization correction. By comparing the polarization value in the current polarization data with the preset polarization tolerance value, it is determined whether the polarization of the corrected mechanical watch meets the tolerance requirements. If the polarization value of the mechanical watch is determined to be less than the polarization tolerance value based on the current polarization data, it indicates that the polarization of the corrected mechanical watch meets the tolerance requirements, and the polarization correction process for the mechanical watch can be terminated.

[0145] In one embodiment, after performing the steps of acquiring the current tone signal set of the mechanical watch and obtaining the current polarization data based on the current tone signal set, the polarization detection unit is further configured to:

[0146] If the polarization value of the mechanical watch is determined to be greater than the polarization tolerance value based on the current polarization data, then the current balance wheel image set obtained by the image acquisition module for image acquisition of the balance wheel 4 at the system time of the first current watch tone signal in the current watch tone signal set is obtained, and the current balance wheel direction corresponding to the first current watch tone signal in the current watch tone signal set is identified based on the current balance wheel image set.

[0147] The system time corresponding to each current tone signal in the collected current tone signal set is used to form the current time parameter set;

[0148] The polarization data is updated with the current polarization data, the time parameter set is updated with the current time parameter set, the balance wheel direction is updated with the current balance wheel direction, and the process returns to the step of obtaining the polarization direction based on the time parameter set and the balance wheel direction.

[0149] In this embodiment, if the polarization value of the mechanical watch is determined to be greater than the polarization tolerance value based on the current polarization data, it indicates that the polarization of the corrected mechanical watch still does not meet the tolerance requirements, and the polarization of the mechanical watch needs to be recalibrated. The image acquisition module immediately acquires an image of the balance wheel 4 when the sound sensor acquires the system time corresponding to the first current tone signal in the current tone signal set, thus obtaining the current balance wheel image set. Therefore, after determining that the polarization value of the mechanical watch is greater than the polarization tolerance value, the current balance wheel image set is acquired to identify the current balance wheel direction corresponding to the first current tone signal in the current tone signal set. Furthermore, the current time parameter set is acquired, the polarization data is updated with the current polarization data, the time parameter set is updated with the current time parameter set, and the balance wheel direction is updated with the current balance wheel direction. The process then returns to execute the step of obtaining the polarization direction based on the time parameter set and the balance wheel direction, thereby recalibrating the polarization of the corrected mechanical watch to ensure that the polarization of the mechanical watch meets the tolerance requirements. This improves the accuracy of the polarization correction and the precision of the mechanical watch's polarization.

Based on polarization data and the balance wheel direction, it can quickly determine the angle and direction of rotation required by the adjustment tool, and then quickly adjust the position of the disc pin 41, so that the polarization of the mechanical watch meets the tolerance requirements, and can achieve rapid and quantitative correction of the polarization of the mechanical watch.
