[0001] This invention relates to the field of mechanical watch technology, and in particular to a method, apparatus, computer equipment, and storage medium for precise adjustment of the outer stud of a mechanical watch. Background Technology

[0002] The polarization of a mechanical watch must be controlled within a certain range to ensure reliable and accurate timekeeping. Currently, a watch calibrator is typically used to identify the polarization data of a mechanical watch, and the polarization is adjusted manually. This usually involves adjusting the angle of the outer stud (or outer stud ring), which in turn rotates the inner stud, hairspring, balance axis, double discs, and disc pins by a corresponding angle, bringing the disc pins to a balance position or near an acceptable balance position, thus ensuring the polarization meets the tolerance. However, this manual method of adjusting the polarization of a mechanical watch is inefficient due to the small size of the watch movement components. Summary of the Invention

[0036] Please see Figures 1 to 8 The method for precise adjustment of the outer stud of a mechanical watch provided in this embodiment of the invention includes steps S11 to S16.

[0037] S11. Control the sound sensor to contact the mechanical watch to obtain the watch tone signal, and obtain the first polarization data based on the watch tone signal.

[0038] In this embodiment, the precise adjustment method for the outer stud of a mechanical watch provided by this invention is specifically used to adjust the polarization of a mechanical watch employing a fork-palm escapement mechanism. See also... Figure 2In a mechanical watch with a fork escapement mechanism, the balance wheel 25 and hairspring 20 form a periodic oscillation system with a fixed period T. The system receives energy periodically through the escapement mechanism to maintain its cyclical operation and transmits the number of oscillations to the hands, thus indicating the time. Theoretically, one period T consists of two half-cycles. One half-cycle is the time it takes for the balance wheel and hairspring system to move from the equilibrium position to the amplitude position and back to the equilibrium position. If the two half-cycles take the same amount of time, then the balance wheel and hairspring system is in the equilibrium position, meaning the center line of the disc pin 24 on the balance wheel 25 coincides with the center line 23 connecting the balance wheel 25 and the escapement fork axis.

[0039] When a mechanical watch is running, the escapement mechanism produces three distinct striking sounds at the equilibrium position: a release sound, b impulse sound, and c drop sound. These three striking sounds constitute the watch's chime at the equilibrium position. Figure 3 As shown. Because the position of the outer stud 21 is unsuitable, the center line of the disc pin 24 on the balance wheel 25 does not coincide with the center line 23 connecting the balance wheel 25 and the escapement fork shaft. The balance wheel and hairspring system is not in equilibrium, resulting in different times for the two half-cycles to reach the equilibrium position. Consequently, the time intervals between adjacent tones are also different, leading to a polarization phenomenon. The magnitude of the polarization can be determined by identifying the interval between identical striking tones in adjacent tones produced within a single cycle. See also... Figure 4 The oscillation time t and rotation angle of the escapement mechanism theory The relationship between them can be expressed as: Figure 4 The simple harmonic motion curve is used to represent this, where the amplitude (i.e., the swing amplitude) is A, and the period is T. Within one period T, the theoretical half-period is X = Y = T / 2. However, when the center line of the disc pin 24 on the balance wheel 25 does not coincide with the center line 23 connecting the balance wheel 25 and the escapement fork axis, the time interval between adjacent tones differs, specifically X′ = T / 2 + t. 偏 Y′=T / 2-t 偏 , where t 偏 This is the polarization quantity (i.e., polarization value), measured in milliseconds (ms). Therefore, the polarization value is t. 偏 =|X′-Y′| / 2, based on the tone of a mechanical watch, the current mechanical watch's period, amplitude, and polarization value can be obtained, and polarization data is composed of the period, amplitude, and polarization value.

[0040] The sound of a mechanical watch is picked up by a sound sensor. When the sound sensor comes into contact with the mechanical watch, it can identify sounds such as... Figure 2The indicated tone signal is shown. Therefore, by controlling the sound sensor to contact the mechanical watch, the tone signal of the mechanical watch can be obtained. The sound sensor can effectively contact any identifiable part of the mechanical watch, such as the watch case, watch crystal, or crown. The tone signal can be a signal from different directions according to preset settings. Furthermore, by processing the obtained tone signal, the first polarization data corresponding to the tone signal can be obtained.

[0041] S12. Calculate the first outer pile rotation angle based on the first polarization data and the preset first rotation angle strategy, and determine the first preset rotation direction corresponding to the first outer pile rotation angle.

[0042] In this embodiment, after obtaining the first polarization data, the first outer stud rotation angle needs to be calculated based on the first polarization data and a preset first rotation angle strategy. The first outer stud rotation angle is the angle at which the outer stud 21 is subsequently adjusted. Simultaneously, due to the inherent limitations of the design, the rotation direction of the disc pin 24 (or balance wheel 25) cannot be determined solely by the first polarization data. Therefore, a direction needs to be selected for adjustment. A first preset rotation direction corresponding to the first outer stud rotation angle can be determined based on a pre-set mapping relationship between rotation angle and direction. This allows for subsequent adjustment of the outer stud 21 to rotate the first outer stud rotation angle according to the first preset rotation direction, thereby calibrating the polarization of the mechanical watch.

[0043] In one embodiment, the first polarization data includes a first period, a first swing amplitude, and a first polarization value; the calculation of the first outer pile rotation angle based on the first polarization data and a preset first rotation angle strategy includes:

[0044] The first outer pile rotation angle is calculated based on the first period, the first swing amplitude, the first polarization value, and the first rotation angle strategy.

[0045] The formula corresponding to the rotation angle strategy is as follows: δ is the rotation angle of the first outer pile, A′ is the first swing amplitude, T′ is the first period, and t′ is the first period. 偏 This is the first polarization value.

[0046] In this embodiment, the first polarization data is obtained based on the watch tone signal of the mechanical watch. The actual first period T′, first amplitude A′, and first polarization value t′ of the mechanical watch are identified based on the watch tone signal. 偏 The first period T′, the first swing A′, and the first polarization value t′ in the first polarization data 偏 Substitute the formula corresponding to the rotation angle strategy The rotation angle δ of the first outer pile can be obtained by calculation.

[0047] S13. Perform image recognition on the mechanical watch to obtain recognition data, and determine the tool type and tool adjustment position based on the recognition data, the first preset rotation direction and the preset adjustment mapping relationship.

[0048] In this embodiment, the mechanical watch is image-recognized by a controlled image recognition module to obtain recognition data. Furthermore, the tool type and adjustment position can be determined based on the recognition data, a first preset rotation direction, and a preset adjustment mapping relationship.

[0049] In one embodiment, step S13 includes:

[0050] Image recognition is performed on the mechanical watch to obtain the movement type, adjustment area, and balance wheel rotation center, and the recognition data is formed.

[0051] The tool type is determined based on the movement type and the adjustment mapping relationship;

[0052] The tool adjustment position is determined based on the tool type, the adjustment area, the first preset rotation direction, and the adjustment mapping relationship.

[0053] In this embodiment, the structure of the outer stud 21 may differ for different mechanical watch movements, resulting in different adjustment areas and applicable adjustment tools. However, the adjustment area is generally located on both sides of the outer stud cantilever 27. (See reference...) Figure 5 Generally, the first area 28 and the second area 29 on both sides of the outer stud arm 27 of the movement can be adjusted using an adjusting tool to adjust the polarization of the mechanical watch. When the adjusting tool is used in the first area 28, it should be rotated clockwise; when used in the second area 29, it should be rotated counterclockwise. Different types of adjusting tools have different usage methods. For pin-shaped adjusting tools, the usage is exactly as described above. When the pin-shaped adjusting tool is placed in a different area, it should be rotated according to the clock direction corresponding to that area. For U-shaped adjusting tools (see...),... Figure 6 The U-shaped adjustment tool can be attached to the outer pile cantilever 27 in one go. One side of the tool is positioned in the first area 28, and the other side in the second area 29. Polarization adjustment can be performed bidirectionally, meaning the tool can be rotated clockwise or counterclockwise. Sometimes the outer pile cantilever 27 has a slot, i.e. Figure 5The third region 30 allows for the placement of a needle-shaped adjustment tool for polarization adjustment. Inserting the tool into the third region 30 allows for bidirectional adjustment; the tool can be rotated clockwise or counter-clockwise. Alternatively, a needle-like protrusion can be added between the two sides of the U-shaped adjustment tool before insertion into the third region 30, also allowing for bidirectional adjustment. The adjustment area of ​​the mechanical watch includes a first region 28 and a second region 29. The first region 28 is located to the left of the outer stud arm 27 and is an area that can accommodate the adjustment tool without interfering with other parts. The second region 29 is located to the right of the outer stud arm 27 and to the left of the regulator arm 27 (between the outer stud arm 27 and the regulator arm 27), and is also an area that can accommodate the adjustment tool without interfering with other parts. Optionally, the adjustment area of ​​the mechanical watch may also include a third region 30, located within the slot of the outer stud arm 27.

[0054] The image recognition module performs image recognition on the mechanical watch. Specifically, it compares the watch's movement image with a preset set of movement images to determine the watch's movement type. Then, based on the movement type and adjustment mapping relationship, it determines the appropriate tool type for the watch. Furthermore, a preset target detection model can be used to obtain the watch's adjustment area and balance wheel rotation center 26. Specifically, the tool adjustment position can be determined based on the tool type, adjustment area, first preset rotation direction, and adjustment mapping relationship. For example, referring to Table 1, which shows the adjustment mapping relationship provided in this embodiment, if the watch's movement type is determined to be movement 1, then based on the adjustment mapping relationship, the appropriate tool type is a pin-shaped adjustment tool. Then, based on the identified adjustment area of ​​the watch, including the first area 28 and the second area 29, and the first preset rotation direction corresponding to the rotation direction in the adjustment mapping relationship, when the first preset rotation direction is clockwise, the preset point A position in the first area 28 (e.g., ...) is adjusted. Figure 8 Point A shown is used as the tool adjustment position; when the first preset rotation direction is counterclockwise, the preset point C position (not shown) in the second region 29 is used as the tool adjustment position. The tool adjustment position in the adjustment region, such as the preset point A position in the first region 28, the preset point C position in the second region 29, or the preset point D position (not shown) in the third region 30, is determined after taking into account that the adjustment tool can be accommodated.

[0058] S14. Control the execution device to drive the adjustment tool of the tool type to be inserted into the tool adjustment position, and control the execution device to drive the adjustment tool to rotate the first outer stud rotation angle around the balance wheel rotation center of the mechanical watch in the first preset rotation direction.

[0059] In this embodiment, refer to Figure 7 and Figure 8 After determining the tool type and adjustment position, the control actuator drives the adjustment tool of that type to be inserted into the adjustment position. Once the adjustment tool is inserted into the adjustment position, the control actuator drives the adjustment tool to rotate the outer stud 21 around the balance wheel rotation center 26 of the mechanical watch in a first preset rotation direction by a first preset rotation angle. This, in turn, pushes the outer stud 21 to rotate around the balance wheel rotation center 26, thereby adjusting the position of the outer stud 21 and achieving the adjustment of the mechanical watch's polarization. The balance wheel rotation center 26 is identified through image recognition of the mechanical watch, and the identification data includes the balance wheel rotation center 26. The actuator can be of various types, including a combination of multiple linear actuators, rotation mechanisms, oscillating mechanisms, etc., a multi-axis robotic arm, an XY table, or an XYZ table. The purpose of the actuator is to insert the adjustment tool into the adjustment position and drive the adjustment tool to perform angular or displacement operations. In practice, the adjustment tool is not necessarily inserted vertically into the adjustment position perpendicular to the movement's assembly surface. This is because, due to accuracy issues, the adjustment tool may collide with the outer cantilever 27, potentially damaging the movement. Preferably, the adjustment tool is moved into an adjustment area corresponding to the tool's adjustment position, where it does not contact other parts. After reaching the set depth, the tool is controlled to translate to the desired adjustment position. Optionally, the insertion depth of the adjustment tool can be determined using image recognition, laser recognition, or similar methods.

[0060] In one embodiment, controlling the execution device to drive the adjustment tool to rotate the first outer stud rotation angle around the balance wheel rotation center of the mechanical watch in the first preset rotation direction includes:

[0061] The radius of rotation is determined based on the tool's adjustment position and the center of rotation of the pendulum wheel.

[0062] The circular arc path is obtained based on the rotation radius, the rotation angle of the first outer pile, the preset arc length calculation strategy, the tool adjustment position, and the first preset rotation direction, and the execution device is controlled to drive the adjustment tool to move along the circular arc path.

[0063] Alternatively, a straight path can be obtained based on the rotation radius, the rotation angle of the first outer pile, the preset movement distance strategy, the tool adjustment position, and the first preset rotation direction, and the execution device can be controlled to drive the adjustment tool to move along the straight path.

[0064] In this embodiment, refer to Figure 7 and Figure 8 Adjust the position using tools (e.g.) Figure 7 and Figure 8 A rotation radius is determined by connecting point A (as shown in the diagram) to the center of rotation 26 of the pendulum wheel. This rotation radius allows the actual starting angle of rotation to be obtained, which is then used as the basis for rotating the adjustment tool by the first rotation angle of the outer stake. When the adjustment tool is inserted into the tool adjustment position, it will touch the outer stake cantilever 27. Optionally, a function can be provided to identify when the adjustment tool touches the outer stake cantilever 27. This identification function can be based on electrical factors (e.g., the adjustment tool and the outer stake cantilever 27 creating a circuit), pressure factors (a pressure sensor on the adjustment tool or its connecting structure), or magnetic factors. This ensures that the actual insertion position of the adjustment tool is the correct adjustment position, thus guaranteeing that the rotation radius is the actual radius determined by the line connecting the actual insertion position of the adjustment tool and the center of rotation 26 of the pendulum wheel. Specifically, the actuator can be controlled to drive the adjustment tool in an arc motion to rotate the first outer stake around the center of rotation 26 of the pendulum wheel by an arc angle. The arc length is determined based on the rotation radius, the rotation angle of the first outer stake, and an 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 of the first outer stake, and r is the rotation radius. The arc path is obtained based on the arc length, the tool adjustment position, and the first preset rotation direction. Controlling the actuator to drive the adjustment tool along the arc path allows the adjustment tool to rotate δ around the center of rotation 26 of the pendulum wheel in the first preset rotation direction. Alternatively, the actuator can be controlled to drive the adjustment tool in a straight line motion. The straight line movement distance is determined based on the rotation radius, the rotation angle of the first outer stake, and a movement distance strategy. The formula for the movement distance strategy is L. AB =2rsin(δ / 2), L AB The linear movement distance is δ, the rotation angle of the first outer pile is r, and the rotation radius is r. The linear path is obtained based on the linear movement distance, the tool adjustment position, and the first preset rotation 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. The moving and adjusting tool moves from A to B. The angle of rotation of the adjusting tool around the center of rotation 26 of the pendulum wheel in the first preset rotation direction is δ.

[0065] S15. Obtain the current tone signal of the mechanical watch and obtain the second polarization data based on the current tone signal.

[0066] In this embodiment, after the adjustment tool rotates the first outer stake rotation angle around the center of rotation 26 of the pendulum wheel in the first preset rotation direction, it indicates that the polarization of the mechanical watch has been adjusted. Then, the current tone signal of the mechanical watch is acquired, and the second polarization data is obtained based on the current tone signal, that is, the polarization data of the mechanical watch after adjustment is obtained, so as to detect whether the polarization of the current mechanical watch is accurately adjusted, that is, to detect whether the polarization of the mechanical watch is controlled within a certain range.

[0067] In one embodiment, after step S15, the method further includes:

[0068] If it is determined that the polarization value of the mechanical watch has increased based on the first polarization data and the second polarization data, then the second outer peg rotation angle is obtained according to the preset angle strategy.

[0069] The second preset rotation direction is determined based on the opposite direction of the first preset rotation direction;

[0070] If the tool adjustment position is determined to be a preset bidirectional position, the execution device is controlled to drive the adjustment tool to rotate around the center of rotation of the pendulum wheel by the second outer pile rotation angle in the second preset rotation direction, and then return to the execution step S15;

[0071] If the tool adjustment position is determined to be a preset unidirectional position, then the second tool adjustment position is determined according to the identification data, the second preset rotation direction and the adjustment mapping relationship. The execution device is controlled to drive the adjustment tool to insert into the second tool adjustment position. The execution device is controlled to drive the adjustment tool to rotate the second outer pile rotation angle around the center of rotation of the pendulum wheel in the second preset rotation direction, and then return to the execution step S15.

[0072] In this embodiment, the first polarization data and the second polarization data respectively include the polarization value of the mechanical watch before polarization adjustment (i.e., the first polarization value) and the polarization value after polarization adjustment (i.e., the second polarization value). By comparing the magnitudes of the first polarization value and the second polarization value, it can be determined whether the polarization value of the mechanical watch has increased after adjustment. If it is determined that the polarization value of the mechanical watch has increased, that is, the second polarization value is greater than the first polarization value, it indicates that the direction of polarization adjustment is reversed, that is, the adjustment tool is rotating incorrectly according to the first preset rotation direction, and the adjustment tool should be readjusted in the opposite direction to control the polarization of the mechanical watch within a certain range. Therefore, the second outer stake rotation angle is obtained according to the angle strategy to determine the angle that needs to be rotated in the opposite direction for the reverse adjustment. The second preset rotation direction is determined based on the opposite direction of the first preset rotation direction. If the first preset rotation direction is clockwise, then the second preset rotation direction is counterclockwise; if the first preset rotation direction is counterclockwise, then the second preset rotation direction is clockwise. Furthermore, if the adjustment tool is inserted into a preset bidirectional position, it indicates that the adjustment tool inserted into that position can be used for bidirectional adjustment. This controls the execution device to drive the adjustment tool to rotate the second outer stud around the center 26 of the pendulum wheel in the second preset rotation direction by an angle. The adjustment tool then pushes the outer stud 21 for reverse adjustment and returns to step S15. If the adjustment tool is inserted into a preset unidirectional position, it indicates that the adjustment tool cannot be inserted into that position for bidirectional adjustment. The adjustment tool needs to be pulled out and re-inserted into the adjustment area of ​​the mechanical watch corresponding to the second preset rotation direction. Referring to Table 1 above, the second preset rotation direction corresponds to the rotation direction in the adjustment mapping relationship. Based on the identification data, the second preset rotation direction, and the adjustment mapping relationship, the second tool adjustment position is re-determined. The execution device is then controlled to drive the adjustment tool to be inserted into the second tool adjustment position and rotate the second outer stud around the center 26 of the pendulum wheel in the second preset rotation direction by an angle, thereby completing the reverse adjustment and returning to step S15.

[0073] In one embodiment, obtaining the second outer pile rotation angle according to a preset angle strategy includes:

[0074] The rotation angle of the first outer pile and a preset multiple are obtained according to the angle strategy, and the rotation angle of the second outer pile is calculated based on the product of the rotation angle of the first outer pile and the preset multiple.

[0075] Alternatively, the second polarization data and a preset second rotation angle strategy can be obtained according to the angle strategy, and the second outer pile rotation angle can be calculated based on the second polarization data and the second rotation angle strategy.

[0076] In this embodiment, if the polarization adjustment direction is reversed, the adjustment tool should be readjusted in the opposite direction. The angle of the reverse adjustment (i.e., the second outer pile rotation angle, denoted as δ2) is obtained according to the angle strategy. The first outer pile rotation angle and a preset multiple can be obtained according to the angle strategy, where the preset multiple is 2, the first outer pile rotation angle is δ, and the second outer pile rotation angle δ2 = 2δ. Alternatively, the second polarization data and a preset second rotation angle strategy can be obtained according to the angle strategy. The second outer pile rotation angle δ2 is calculated based on the second polarization data and the second rotation angle strategy. Specifically, the second polarization data includes the second period T", the second swing amplitude A", and the second polarization value t". 偏 By substituting the second polarization data into the formula corresponding to the rotation angle strategy The rotation angle δ2 of the second outer pile can be obtained by calculation.

[0077] In one embodiment, after step S15, the method further includes:

[0078] If it is determined, based on the first polarization data and the second polarization data, that the polarization value of the mechanical watch has decreased, and based on the second polarization data, it is determined that the polarization value of the mechanical watch exceeds the normal value range, then the actuator is controlled to drive the adjustment tool to rotate around the balance wheel's rotation center by a preset correction angle in the first preset rotation direction, and the adjustment process is controlled to end.

[0079] In this embodiment, if the first polarization value in the first polarization data is greater than the second polarization value in the second polarization data, it is determined that the polarization value of the mechanical watch has decreased, indicating that the direction of polarization adjustment is correct, that is, the adjustment tool is rotating in the first preset rotation direction. Then, the second polarization value in the second polarization data is used to detect whether the adjusted polarization value of the mechanical watch exceeds the theoretical range (i.e., the normal value range). If it is determined that the polarization value of the mechanical watch exceeds the normal value range, the execution device is controlled to drive the adjustment tool to rotate around the center of the balance wheel in the first preset rotation direction by a preset correction angle. The correction angle is set according to theory or empirical formulas, thereby improving the accuracy of the polarization of the mechanical watch, improving the accuracy of the polarization adjustment of the mechanical watch, and controlling the end of the adjustment process to end the adjustment of the mechanical watch.

[0080] S16. If it is determined that the polarization value of the mechanical watch has decreased based on the first polarization data and the second polarization data, and it is determined based on the second polarization data that the polarization value of the mechanical watch has not exceeded the preset normal value range, then the adjustment process ends.

[0081] In this embodiment, if the first polarization value in the first polarization data is greater than the second polarization value in the second polarization data, it is determined that the polarization value of the mechanical watch has decreased, indicating that the direction of polarization adjustment is correct. Simultaneously, the second polarization value in the second polarization data confirms that the adjusted polarization value of the mechanical watch does not exceed the normal range, indicating that the polarization of the mechanical watch has been controlled within a certain range, and the polarization adjustment of the mechanical watch is accurate. The adjustment process can then be terminated, ending the adjustment of the mechanical watch.

[0082] This invention discloses a method for precise adjustment of the outer stud of a mechanical watch. Based on the polarization data of the mechanical watch, the method controls the execution device to drive the adjustment tool to perform polarization adjustment, which can accurately and quickly adjust the polarization of the mechanical watch and improve the adjustment efficiency.

[0083] This invention also provides a device for precisely adjusting the outer stud of a mechanical watch. This device is used to perform any of the aforementioned methods for precisely adjusting the outer stud of a mechanical watch. Specifically, please refer to... Figure 9 , Figure 9 This is a schematic block diagram of a mechanical watch stud precision adjustment device according to an embodiment of the present invention. The mechanical watch stud precision adjustment device 100 provided in this embodiment of the present invention includes a first data acquisition unit 11, a first angle acquisition unit 12, an image recognition unit 13, a rotation control unit 14, a second data acquisition unit 15, and an adjustment end unit 16.

[0084] The first data acquisition unit 11 is used to control the sound sensor to contact the mechanical watch to obtain the watch sound signal, and to obtain the first polarization data based on the watch sound signal.

[0085] In this embodiment, the precise adjustment method for the outer stud of a mechanical watch provided by this invention is specifically used to adjust the polarization of a mechanical watch employing a fork escapement mechanism. In a mechanical watch with a fork escapement mechanism, the balance wheel 25 and hairspring 20 form a periodic oscillation system with a fixed period T. The system receives energy periodically through the escapement mechanism to maintain its periodic operation, while simultaneously transmitting the number of oscillations to the hands, thus indicating the time. Theoretically, one period T includes two half-cycles. One half-cycle is the time taken for the balance wheel and hairspring system to move from the equilibrium position to the amplitude position and back to the equilibrium position. If the time taken for these two half-cycles is the same, then the balance wheel and hairspring system is at the equilibrium position, meaning the center line of the disc pin 24 on the balance wheel 25 coincides with the center line 23 connecting the balance wheel 25 and the escapement fork axis. (See reference...) Figure 2 .

[0086] When a mechanical watch is running, the escapement mechanism produces three distinct striking sounds at the equilibrium position: a release sound, b impulse sound, and c drop sound. These three striking sounds constitute the watch's chime at the equilibrium position. Figure 3 As shown. Because the position of the outer stud 21 is unsuitable, the center line of the disc pin 24 on the balance wheel 25 does not coincide with the center line 23 connecting the balance wheel 25 and the escapement fork shaft. The balance wheel and hairspring system is not in equilibrium, resulting in different times for the two half-cycles to reach the equilibrium position. Consequently, the time intervals between adjacent tones are also different, leading to a polarization phenomenon. The magnitude of the polarization can be determined by identifying the interval between identical striking tones in adjacent tones produced within a single cycle. See also... Figure 4 The oscillation time t and rotation angle of the escapement mechanism theory The relationship between them can be expressed as: Figure 4 The simple harmonic motion curve is used to represent this, where the amplitude (i.e., the swing amplitude) is A, and the period is T. Within one period T, the theoretical half-period is X = Y = T / 2. However, when the center line of the disc pin 24 on the balance wheel 25 does not coincide with the center line 23 connecting the balance wheel 25 and the escapement fork axis, the time interval between adjacent tones differs, specifically X′ = T / 2 + t. 偏 Y′=T / 2-t 偏 , where t 偏 This is the polarization quantity (i.e., polarization value), measured in milliseconds (ms). Therefore, the polarization value is t. 偏 =|X′-Y′| / 2, based on the tone of a mechanical watch, the current mechanical watch's period, amplitude, and polarization value can be obtained, and polarization data is composed of the period, amplitude, and polarization value.

[0087] The sound of a mechanical watch is picked up by a sound sensor. When the sound sensor comes into contact with the mechanical watch, it can identify sounds such as... Figure 2 The indicated tone signal is shown. Therefore, by controlling the sound sensor to contact the mechanical watch, the tone signal of the mechanical watch can be obtained. The sound sensor can effectively contact any identifiable part of the mechanical watch, such as the watch case, watch crystal, or crown. The tone signal can be a signal from different directions according to preset settings. Furthermore, by processing the obtained tone signal, the first polarization data corresponding to the tone signal can be obtained.

[0088] The first angle acquisition unit 12 is used to calculate the first outer pile rotation angle based on the first polarization data and the preset first rotation angle strategy, and to determine the first preset rotation direction corresponding to the first outer pile rotation angle.

[0089] In this embodiment, after obtaining the first polarization data, the first outer stud rotation angle needs to be calculated based on the first polarization data and a preset first rotation angle strategy. The first outer stud rotation angle is the angle at which the outer stud 21 is subsequently adjusted. Simultaneously, due to the inherent limitations of the design, the rotation direction of the disc pin 24 (or balance wheel 25) cannot be determined solely by the first polarization data. Therefore, a direction needs to be selected for adjustment. A first preset rotation direction corresponding to the first outer stud rotation angle can be determined based on a pre-set mapping relationship between rotation angle and direction. This allows for subsequent adjustment of the outer stud 21 to rotate the first outer stud rotation angle according to the first preset rotation direction, thereby calibrating the polarization of the mechanical watch.

[0090] In one embodiment, the first polarization data includes a first period, a first swing amplitude, and a first polarization value; when the first angle acquisition unit 12 performs the step of calculating the first outer pile rotation angle based on the first polarization data and a preset first rotation angle strategy, it is specifically used for:

[0091] The first outer pile rotation angle is calculated based on the first period, the first swing amplitude, the first polarization value, and the first rotation angle strategy.

[0092] The formula corresponding to the rotation angle strategy is as follows: δ is the rotation angle of the first outer pile, A′ is the first swing amplitude, T′ is the first period, and t′ is the first period. 偏 This is the first polarization value.

[0093] In this embodiment, the first polarization data is obtained based on the watch tone signal of the mechanical watch. The actual first period T′, first amplitude A′, and first polarization value t′ of the mechanical watch are identified based on the watch tone signal. 偏 The first period T′, the first swing A′, and the first polarization value t′ in the first polarization data 偏 Substitute the formula corresponding to the rotation angle strategy The rotation angle δ of the first outer pile can be obtained by calculation.

[0094] The image recognition unit 13 is used to perform image recognition on the mechanical watch to obtain recognition data, and to determine the tool type and tool adjustment position based on the recognition data, the first preset rotation direction and the preset adjustment mapping relationship.

[0095] In this embodiment, the mechanical watch is image-recognized by a controlled image recognition module to obtain recognition data. Furthermore, the tool type and adjustment position can be determined based on the recognition data, the first preset rotation direction, and a preset adjustment mapping relationship.

[0096] In one embodiment, the image recognition unit 13 is specifically used for:

[0097] Image recognition is performed on the mechanical watch to obtain the movement type, adjustment area, and balance wheel rotation center, and the recognition data is formed.

[0098] The tool type is determined based on the movement type and the adjustment mapping relationship;

[0099] The tool adjustment position is determined based on the tool type, the adjustment area, the first preset rotation direction, and the adjustment mapping relationship.

[0100] In this embodiment, the structure of the outer stud 21 may differ for different mechanical watch movements, resulting in different adjustment areas and applicable adjustment tools. However, the adjustment area is generally located on both sides of the outer stud cantilever 27. (See reference...) Figure 5 Generally, the first area 28 and the second area 29 on both sides of the outer stud arm 27 of the movement can be adjusted using an adjusting tool to adjust the polarization of the mechanical watch. When the adjusting tool is used in the first area 28, it should be rotated clockwise; when used in the second area 29, it should be rotated counterclockwise. Different types of adjusting tools have different usage methods. For pin-shaped adjusting tools, the usage is exactly as described above. When the pin-shaped adjusting tool is placed in a different area, it should be rotated according to the clock direction corresponding to that area. For U-shaped adjusting tools (see...),... Figure 6 The U-shaped adjustment tool can be attached to the outer pile cantilever 27 in one go. One side of the tool is positioned in the first area 28, and the other side in the second area 29. Polarization adjustment can be performed bidirectionally, meaning the tool can be rotated clockwise or counterclockwise. Sometimes the outer pile cantilever 27 has a slot, i.e. Figure 5 The third region 30 allows for the placement of a needle-shaped adjustment tool for polarization adjustment. Inserting the tool into the third region 30 allows for bidirectional adjustment; the tool can be rotated clockwise or counter-clockwise. Alternatively, a needle-like protrusion can be added between the two sides of the U-shaped adjustment tool before insertion into the third region 30, also allowing for bidirectional adjustment. The adjustment area of ​​the mechanical watch includes a first region 28 and a second region 29. The first region 28 is located to the left of the outer stud arm 27 and is an area that can accommodate the adjustment tool without interfering with other parts. The second region 29 is located to the right of the outer stud arm 27 and to the left of the regulator arm 27 (between the outer stud arm 27 and the regulator arm 27), and is also an area that can accommodate the adjustment tool without interfering with other parts. Optionally, the adjustment area of ​​the mechanical watch may also include a third region 30, located within the slot of the outer stud arm 27.

[0101] The image recognition module performs image recognition on the mechanical watch. Specifically, it compares the watch's movement image with a preset set of movement images to determine the watch's movement type. Then, based on the movement type and adjustment mapping relationship, it determines the appropriate tool type for the watch. Furthermore, a preset target detection model can be used to obtain the watch's adjustment area and balance wheel rotation center 26. Specifically, the tool adjustment position can be determined based on the tool type, adjustment area, first preset rotation direction, and adjustment mapping relationship. For example, referring to Table 1 above, if the watch's movement type is determined to be movement 1, then based on the adjustment mapping relationship, the appropriate tool type is a pin-shaped adjustment tool. Then, based on the identified adjustment area of ​​the watch, including the first area 28 and the second area 29, and the first preset rotation direction corresponding to the rotation direction in the adjustment mapping relationship, when the first preset rotation direction is clockwise, the preset point A position in the first area 28 (e.g., ...) is adjusted. Figure 8 Point A shown is used as the tool adjustment position; when the first preset rotation direction is counterclockwise, the preset point C position (not shown) in the second region 29 is used as the tool adjustment position. The tool adjustment position in the adjustment region, such as the preset point A position in the first region 28, the preset point C position in the second region 29, or the preset point D position (not shown) in the third region 30, is determined after taking into account that the adjustment tool can be accommodated.

[0102] The rotation control unit 14 is used to control the execution device to drive the adjustment tool of the tool type to be inserted into the tool adjustment position, and to control the execution device to drive the adjustment tool to rotate the first outer stud rotation angle around the balance wheel rotation center of the mechanical watch in the first preset rotation direction.

[0103] In this embodiment, refer to Figure 7 and Figure 8After determining the tool type and adjustment position, the control actuator drives the adjustment tool of that type to be inserted into the adjustment position. Once the adjustment tool is inserted into the adjustment position, the control actuator drives the adjustment tool to rotate the outer stud 21 around the balance wheel rotation center 26 of the mechanical watch in a first preset rotation direction by a first preset rotation angle. This, in turn, pushes the outer stud 21 to rotate around the balance wheel rotation center 26, thereby adjusting the position of the outer stud 21 and achieving the adjustment of the mechanical watch's polarization. The balance wheel rotation center 26 is identified through image recognition of the mechanical watch, and the identification data includes the balance wheel rotation center 26. The actuator can be of various types, including a combination of multiple linear actuators, rotation mechanisms, oscillating mechanisms, etc., a multi-axis robotic arm, an XY table, or an XYZ table. The purpose of the actuator is to insert the adjustment tool into the adjustment position and drive the adjustment tool to perform angular or displacement operations. In practice, the adjustment tool is not necessarily inserted vertically into the adjustment position perpendicular to the movement's assembly surface. This is because, due to accuracy issues, the adjustment tool may collide with the outer cantilever 27, potentially damaging the movement. Preferably, the adjustment tool is moved into an adjustment area corresponding to the tool's adjustment position, where it does not contact other parts. After reaching the set depth, the tool is controlled to translate to the desired adjustment position. Optionally, the insertion depth of the adjustment tool can be determined using image recognition, laser recognition, or similar methods.

[0104] In one embodiment, when the rotation control unit 14 executes the step of controlling the execution device to drive the adjustment tool to rotate the first outer stud around the balance wheel rotation center of the mechanical watch in the first preset rotation direction, it is specifically used for:

[0105] The radius of rotation is determined based on the tool's adjustment position and the center of rotation of the pendulum wheel.

[0106] The circular arc path is obtained based on the rotation radius, the rotation angle of the first outer pile, the preset arc length calculation strategy, the tool adjustment position, and the first preset rotation direction, and the execution device is controlled to drive the adjustment tool to move along the circular arc path.

[0107] Alternatively, a straight path can be obtained based on the rotation radius, the rotation angle of the first outer pile, the preset movement distance strategy, the tool adjustment position, and the first preset rotation direction, and the execution device can be controlled to drive the adjustment tool to move along the straight path.

[0108] In this embodiment, refer to Figure 7 and Figure 8 Adjust the position using tools (e.g.) Figure 7 and Figure 8A rotation radius is determined by connecting point A (as shown in the diagram) to the center of rotation 26 of the pendulum wheel. This rotation radius allows the actual starting angle of rotation to be obtained, which is then used as the basis for rotating the adjustment tool by the first rotation angle of the outer stake. When the adjustment tool is inserted into the tool adjustment position, it will touch the outer stake cantilever 27. Optionally, a function can be provided to identify when the adjustment tool touches the outer stake cantilever 27. This identification function can be based on electrical factors (e.g., the adjustment tool and the outer stake cantilever 27 creating a circuit), pressure factors (a pressure sensor on the adjustment tool or its connecting structure), or magnetic factors. This ensures that the actual insertion position of the adjustment tool is the correct adjustment position, thus guaranteeing that the rotation radius is the actual radius determined by the line connecting the actual insertion position of the adjustment tool and the center of rotation 26 of the pendulum wheel. Specifically, the actuator can be controlled to drive the adjustment tool in an arc motion to rotate the first outer stake around the center of rotation 26 of the pendulum wheel by an arc angle. The arc length is determined based on the rotation radius, the rotation angle of the first outer stake, and an 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 of the first outer stake, and r is the rotation radius. The arc path is obtained based on the arc length, the tool adjustment position, and the first preset rotation direction. Controlling the actuator to drive the adjustment tool along the arc path allows the adjustment tool to rotate δ around the center of rotation 26 of the pendulum wheel in the first preset rotation direction. Alternatively, the actuator can be controlled to drive the adjustment tool in a straight line motion. The straight line movement distance is determined based on the rotation radius, the rotation angle of the first outer stake, and a movement distance strategy. The formula for the movement distance strategy is L. AB =2rsin(δ / 2), L AB The linear movement distance is δ, the rotation angle of the first outer pile is r, and the rotation radius is r. The linear path is obtained based on the linear movement distance, the tool adjustment position, and the first preset rotation 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. The moving and adjusting tool moves from A to B. The angle of rotation of the adjusting tool around the center of rotation 26 of the pendulum wheel in the first preset rotation direction is δ.

[0109] The second data acquisition unit 15 is used to acquire the current tone signal of the mechanical watch and obtain second polarization data based on the current tone signal.

[0110] In this embodiment, after the adjustment tool rotates the first outer stake rotation angle around the center of rotation 26 of the pendulum wheel in the first preset rotation direction, it indicates that the polarization of the mechanical watch has been adjusted. Then, the current tone signal of the mechanical watch is acquired, and the second polarization data is obtained based on the current tone signal, that is, the polarization data of the mechanical watch after adjustment is obtained, so as to detect whether the polarization of the current mechanical watch is accurately adjusted, that is, to detect whether the polarization of the mechanical watch is controlled within a certain range.

[0111] In one embodiment, the precision adjustment device for the mechanical watch stud 21 further includes an enlargement adjustment unit. After the second data acquisition unit 15 performs the steps of acquiring the current tone signal of the mechanical watch and obtaining the second polarization data based on the current tone signal, the enlargement adjustment unit is specifically used for:

[0112] If it is determined that the polarization value of the mechanical watch has increased based on the first polarization data and the second polarization data, then the second outer peg rotation angle is obtained according to the preset angle strategy.

[0113] The second preset rotation direction is determined based on the opposite direction of the first preset rotation direction;

[0114] If the tool adjustment position is determined to be a preset bidirectional position, then the execution device is controlled to drive the adjustment tool to rotate around the balance wheel rotation center 26 by a second outer stud rotation angle in the second preset rotation direction, and then return to execute the step of obtaining the current watch tone signal of the mechanical watch and obtaining the second polarization data based on the current watch tone signal;

[0115] If the tool adjustment position is determined to be a preset unidirectional position, then the second tool adjustment position is determined according to the identification data, the second preset rotation direction and the adjustment mapping relationship. The execution device is controlled to drive the adjustment tool to insert into the second tool adjustment position. The execution device is controlled to drive the adjustment tool to rotate the second outer stud rotation angle around the balance wheel rotation center 26 according to the second preset rotation direction. Then, the execution returns to the step of obtaining the current watch tone signal of the mechanical watch and obtaining the second polarization data according to the current watch tone signal.

[0116] In this embodiment, the first polarization data and the second polarization data respectively include the polarization value of the mechanical watch before polarization adjustment (i.e., the first polarization value) and the polarization value after polarization adjustment (i.e., the second polarization value). By comparing the magnitudes of the first polarization value and the second polarization value, it can be determined whether the polarization value of the mechanical watch has increased after adjustment. If it is determined that the polarization value of the mechanical watch has increased, that is, the second polarization value is greater than the first polarization value, it indicates that the direction of polarization adjustment is reversed, that is, the adjustment tool is rotating incorrectly according to the first preset rotation direction, and the adjustment tool should be readjusted in the opposite direction to control the polarization of the mechanical watch within a certain range. Therefore, the second outer stake rotation angle is obtained according to the angle strategy to determine the angle that needs to be rotated in the opposite direction for the reverse adjustment. The second preset rotation direction is determined based on the opposite direction of the first preset rotation direction. If the first preset rotation direction is clockwise, then the second preset rotation direction is counterclockwise; if the first preset rotation direction is counterclockwise, then the second preset rotation direction is clockwise. Furthermore, if the adjustment tool is inserted into a preset bidirectional position, it means that the adjustment tool inserted into that adjustment position can be used for bidirectional adjustment, thereby controlling the execution device to drive the adjustment tool to rotate around the center of rotation 26 of the balance wheel in the second preset rotation direction by the second outer stud rotation angle. The adjustment tool pushes the outer stud 21 to make reverse adjustment, and returns to the step of obtaining the current tone signal of the mechanical watch and obtaining the second polarization data based on the current tone signal. If the adjustment tool is inserted into a preset unidirectional position, it means that the adjustment tool cannot be adjusted bidirectionally when inserted into that position. The adjustment tool needs to be pulled out and re-inserted into the adjustment area of ​​the mechanical watch corresponding to the second preset rotation direction. Referring to Table 1 above, the second preset rotation direction corresponds to the rotation direction in the adjustment mapping relationship. Based on the identification data, the second preset rotation direction and the adjustment mapping relationship, the second tool adjustment position is re-determined. The execution device is controlled to drive the adjustment tool to be inserted into the second tool adjustment position and rotate the second outer stud around the center of rotation 26 of the balance wheel according to the second preset rotation direction, thereby completing the reverse adjustment. Then, the process returns to the step of obtaining the current tone signal of the mechanical watch and obtaining the second polarization data based on the current tone signal.

[0117] In one embodiment, obtaining the second outer pile rotation angle according to a preset angle strategy includes:

[0118] The rotation angle of the first outer pile and a preset multiple are obtained according to the angle strategy, and the rotation angle of the second outer pile is calculated based on the product of the rotation angle of the first outer pile and the preset multiple.

[0119] Alternatively, the second polarization data and a preset second rotation angle strategy can be obtained according to the angle strategy, and the second outer pile rotation angle can be calculated based on the second polarization data and the second rotation angle strategy.

[0120] In this embodiment, if the polarization adjustment direction is reversed, the adjustment tool should be readjusted in the opposite direction. The angle of the reverse adjustment (i.e., the second outer pile rotation angle, denoted as δ2) is obtained according to the angle strategy. The first outer pile rotation angle and a preset multiple can be obtained according to the angle strategy, where the preset multiple is 2, the first outer pile rotation angle is δ, and the second outer pile rotation angle δ2 = 2δ. Alternatively, the second polarization data and a preset second rotation angle strategy can be obtained according to the angle strategy. The second outer pile rotation angle δ2 is calculated based on the second polarization data and the second rotation angle strategy. Specifically, the second polarization data includes the second period T", the second swing amplitude A", and the second polarization value t". 偏 By substituting the second polarization data into the formula corresponding to the rotation angle strategy The rotation angle δ2 of the second outer pile can be obtained by calculation.

[0121] In one embodiment, the mechanical watch external stud precision adjustment device further includes a correction and adjustment unit. After the second data acquisition unit 15 performs the steps of acquiring the current tone signal of the mechanical watch and obtaining the second polarization data based on the current tone signal, the correction and adjustment unit is specifically used for:

[0122] If it is determined, based on the first polarization data and the second polarization data, that the polarization value of the mechanical watch has decreased, and based on the second polarization data, it is determined that the polarization value of the mechanical watch exceeds the normal value range, then the actuator is controlled to drive the adjustment tool to rotate around the balance wheel's rotation center by a preset correction angle in the first preset rotation direction, and the adjustment process is controlled to end.

[0123] In this embodiment, if the first polarization value in the first polarization data is greater than the second polarization value in the second polarization data, it is determined that the polarization value of the mechanical watch has decreased, indicating that the direction of polarization adjustment is correct, that is, the adjustment tool is rotating in the first preset rotation direction. Then, the second polarization value in the second polarization data is used to detect whether the adjusted polarization value of the mechanical watch exceeds the theoretical range (i.e., the normal value range). If it is determined that the polarization value of the mechanical watch exceeds the normal value range, the execution device is controlled to drive the adjustment tool to rotate around the center of the balance wheel in the first preset rotation direction by a preset correction angle. The correction angle is set according to theory or empirical formulas, thereby improving the accuracy of the polarization of the mechanical watch, improving the accuracy of the polarization adjustment of the mechanical watch, and controlling the end of the adjustment process to end the adjustment of the mechanical watch.

[0124] The calibration termination unit is used to control the termination of the calibration process if it is determined, based on the first polarization data and the second polarization data, that the polarization value of the mechanical watch has decreased, and based on the second polarization data, it is determined that the polarization value of the mechanical watch has not exceeded the preset normal value range.

[0125] In this embodiment, if the first polarization value in the first polarization data is greater than the second polarization value in the second polarization data, it is determined that the polarization value of the mechanical watch has decreased, indicating that the direction of polarization adjustment is correct. Simultaneously, the second polarization value in the second polarization data confirms that the adjusted polarization value of the mechanical watch does not exceed the normal range, indicating that the polarization of the mechanical watch has been controlled within a certain range, and the polarization adjustment of the mechanical watch is accurate. The adjustment process can then be terminated, ending the adjustment of the mechanical watch.

[0126] The present invention discloses a device for precise adjustment of the outer stud of a mechanical watch, used to perform any embodiment of the aforementioned method for precise adjustment of the outer stud of a mechanical watch. It can control the execution device to drive the adjustment tool to perform polarization adjustment based on the polarization data of the mechanical watch, and can accurately and quickly adjust the polarization of the mechanical watch, thereby improving the adjustment efficiency.

[0127] The aforementioned method for precisely adjusting the outer stud of a mechanical watch can be implemented as a computer program, which can be used in various ways, such as... Figure 10 It runs on the computer device shown.
