Description

Technical Field

[0001] This invention relates to the field of watch accuracy adjustment technology, and in particular to a watch head timekeeping accuracy adjustment system and method. Background Technology

[0002] In the current mechanical watch manufacturing process, after assembling all the parts, the watch's polarization data and instantaneous daily rate data need to be adjusted. Polarization data and instantaneous daily rate data are two important parameters used to evaluate the timekeeping accuracy of a mechanical watch. Polarization data refers to the difference in time required for the balance wheel to swing to the left and right, while instantaneous daily rate data is the timekeeping error data measured by a watch calibrator or other sensing instruments. In the current mechanical watch accuracy adjustment process, operators need to manually adjust the polarization data and instantaneous daily rate data. This accuracy adjustment method is not only inefficient but also difficult to guarantee accuracy. Summary of the Invention

[0005] Secondly, embodiments of the present invention also provide a method for adjusting the timekeeping accuracy of a watch head, applied to the watch head timekeeping accuracy adjustment system as described in the first aspect. The method includes: a control unit acquiring polarization data and instantaneous daily rate data of the watch head via a sensing device; if there is adjustable unqualified data in the polarization data and the instantaneous daily rate data, the control unit adjusts the posture of the watch head using a robotic arm to expose an insertable position for an adjusting body in the movement; the control unit acquires a first movement image of the movement via a side camera, and determines a first insertion position and a second insertion position in the movement corresponding to the adjusting body based on the first movement image, the polarization data, and the instantaneous daily rate data; wherein the first insertion position is used to adjust the polarization data.

[0022] This invention provides a watch head 20 timekeeping accuracy adjustment system 10, including a control unit 110, a robotic arm 120, a watch head clamp 140, a side camera 150, and a fixedly mounted adjustment body 160. The control unit 110 is electrically connected to the robotic arm 120. The end of the robotic arm 120 is provided with a sensor 130 and a gripper 121. The top of the watch head clamp 140 can hold the watch head 20. The robotic arm 120 can move the sensor 130 and the gripper 121 to the watch head clamp 140. The sensor 130 can abut against the end of the watch head 20 away from the watch head clamp 140 to fix the watch head 20 on the watch head clamp 140. The gripper 121 can be fixedly clamped from both sides of the watch head clamp 140. The robotic arm 120 holds the watch head clamp 140; the robotic arm 120 can move the watch head clamp 140 holding the watch head 20 to one side of the adjustment body 160 and the side camera 150; the adjustment body 160 can insert the movement 210 of the watch head 20 from the bottom end of the watch head 20 and adjust the timekeeping accuracy; the sensing device 130 is used to transmit the polarization data and instantaneous daily rate data of the watch head 20 to the control unit 110; the side camera 150 is used to capture the movement 210 image of the movement 210; the control unit 110 is used to control the movement of the robotic arm 120 relative to the adjustment body 160 according to the polarization data, the instantaneous daily rate data and the movement 210 image, so that the adjustment body 160 adjusts the timekeeping accuracy of the movement 210.

[0023] In this embodiment, the control unit 110 is a module responsible for receiving and processing data, as well as controlling the robotic arm 120. Specifically, it can be an operating terminal with a processor. The robotic arm 120 has a base, which is a structure fixedly installed in the operating space for fixation. The end of the robotic arm 120 is movably connected to the base, allowing it to move to any position in the operating space in response to the control unit 110. The meter clamp 140 is a device for clamping the meter head 20. The meter head 20 can be divided into a glass at the top, lugs on both sides, and a movement 210 at the bottom. The top of the meter clamp 140 has a protruding lug retainer for engaging the lugs. The meter head 20 can be stably fixed to the top of the meter clamp 140 through the interlocking of the lugs and the lug retainer, without rotation. The top of the watch head clamp 140 is also provided with a through hole, which allows the movement 210 located at the bottom of the watch head 20 to be exposed at the bottom of the watch head clamp 140. In subsequent processes, the adjustment body 160 can be inserted into the movement 210 from the bottom of the watch head clamp 140 for precision adjustment.

[0024] The gripper 121 at the end of the robotic arm 120 can securely hold the meter holder 140 from both sides. Before gripping, the meter 20 has been placed at the top of the meter holder 140. When the robotic arm 120 moves downward from the top of the meter holder 140 and grips the meter holder 140, the sensing component comes into contact with the glass of the meter 20. The top and bottom of the meter 20 are gripped by the sensing component and the meter holder 140, respectively. Thus, it can be held by the robotic arm 120 along with the meter holder 140, and the meter 20 will not fall out of the meter holder 140 no matter what angle the robotic arm 120 rotates. After the sensing component comes into contact with the meter 20, it can directly acquire the polarization data and instantaneous daily rate data of the meter 20 and transmit them to the control unit 110 for analysis.

[0025] The side camera 150 and the adjustment body 160 are two other components fixedly installed in the operating space. The side camera 150 is located to one side of the adjustment body 160. When the robotic arm 120 moves the dial indicator 20 and the dial indicator clamp 140 to the end of the adjustment body 160 where the movement 210 needs to be inserted, the side camera 150 can face the movement 210 and the adjustment body 160 directly and capture images of the movement 210. It can also transmit the captured images of the movement 210 and the adjustment body 160 to the control unit 110 for analysis. It is understood that the adjustment body 160 is fixed, and its adjustment function is achieved by the robotic arm 120 actively moving the movement 210 relative to the adjustment body 160. By having the control unit 110 actively drive the dial indicator 20 for precision adjustment, efficiency and accuracy can be improved. The adjusting body 160 can be a rod-shaped structure with one end set as an adjusting tip. The diameter of the adjusting tip is smaller than the gap between the various components in the movement 210. Thus, the adjusting tip in the adjusting body 160 can be smoothly inserted into the movement 210 for precision adjustment.

[0026] In one embodiment, the mechanism 210 includes an automatic hammer 211, an outer stud 212, and a speed control needle 213; the automatic hammer 211, the outer stud 212, and the speed control needle 213 are all rotatably disposed inside the mechanism 210; when the automatic hammer 211 rotates in the direction of gravity under the action of gravity, the automatic hammer 211 may be directly opposite the outer stud 212 and the speed control needle 213 and located between the outer stud 212 and the speed control needle 213 and the adjusting body 160, or may be opposite the outer stud 212 and the speed control needle. 213 are offset so that the outer stud 212 and the regulator 213 are directly opposite the adjusting body 160; the adjusting body 160 can abut against one side of the outer stud 212 or one side of the regulator 213; when the meter head 20 is driven by the robotic arm 120 and moves relative to the adjusting body 160, the outer stud 212 or the regulator 213 is driven to rotate by the adjusting body 160 to adjust the timekeeping accuracy; wherein, the outer stud 212 is used to adjust the polarization data; the regulator 213 is used to adjust the instantaneous daily rate data.

[0027] In this embodiment, the automatic hammer 211 is a rotatable structure located at the bottom of the watch head 20. Its fan-shaped shape allows it to obscure other components of the movement 210 within the cylindrical watch head 20. The rotation axis of the automatic hammer 211 coincides with the central axis of the cylindrical watch head 20. When the watch head 20 is rotated by the robotic arm 120, the automatic hammer 211 rotates in the direction of gravity due to gravity. Since the automatic hammer 211 only obscures a portion of the structure within the movement 210, when it rotates to a specific position, it exposes the outer stud 212 and the regulator needle 213 within the movement 210, allowing the adjusting body 160 to actuate either the outer stud 212 or the regulator needle 213.

[0028] In one embodiment, the sensing device 130 includes a telescopic assembly 131, a connecting plate 132, a sensor 133, a buffer block 134, and a compression spring 135; one end of the telescopic assembly 131 is fixedly connected to the robotic arm 120, and the other end of the telescopic assembly 131 is telescopically connected to one end of the connecting plate 132; the other end of the connecting plate 132 is connected to the top end of the buffer block 134; the sensor 133 passes through the buffer block 134, and the top and bottom ends of the sensor 133 protrude from the top and bottom ends of the buffer block 134, respectively; the compression spring 135... A spring 135 is disposed at the top of the connecting plate 132, and the compression spring 135 abuts against the top of the sensor 133; the sensor 133 is communicatively connected to the control unit 110, and is used to acquire the polarization data and the instantaneous daily rate data and transmit them to the control unit 110; when the sensing device 130 abuts against the meter head 20 located at the top of the meter head clamp 140, the top of the sensor 133 moves away from the buffer block 134, and the bottom end of the buffer block 134 and the bottom end of the sensor 133 are both attached to the top of the meter head 20.

[0029] In this embodiment, the telescopic component 131 can be a telescopic cylinder or other component capable of axial extension and retraction, which can drive the entire assembly formed by the connecting plate 132, sensor 133, buffer block 134, and compression spring 135 to move axially. When the gripper 121 of the robotic arm 120 clamps onto both sides of the meter head clamp 140, the telescopic component 131 drives the entire assembly formed by the connecting plate 132, sensor 133, buffer block 134, and compression spring 135 to move closer to the meter head 20. During this process, the sensor 133, protruding from the bottom of the buffer block 134, first contacts the glass at the top of the meter head 20 and is pushed upward by the meter head 20, with the top of the sensor 133 moving away from the buffer block 134; subsequently, the bottom end of the buffer block 134 abuts against the glass at the top of the meter head 20, together with the sensor 133, abutting against the meter head 20. At this time, the buffer block 134 and the sensor 133 together fix the meter head 20 onto the meter head clamp 140. Since the top of sensor 133 is connected to compression spring 135, after the accuracy adjustment is completed, the telescopic assembly 131 drives the entire assembly formed by connecting plate 132, sensor 133, buffer block 134, and compression spring 135 to move away from the meter head 20. Sensor 133 can rebound via compression spring 135, thus returning to its original position. The central axis of connecting plate 132 can be perpendicular to the moving axis of telescopic assembly 131. Connecting plate 132 can extend from between grippers 121 above the meter head 20, aligning buffer block 134 and sensor 133 with the top of meter head 20. Sensor 133 can sensitively detect the polarization data and instantaneous daily rate data of meter head 20 and transmit them to control unit 110. Buffer block 134 prevents pressure from damaging meter head 20.

[0030] In one embodiment, the end of the robotic arm 120 is also provided with a suction cup 122; the suction cup 122 can be attracted to the top of the meter head 20 for transporting the meter head 20 to or away from the meter head clamp 140.

[0031] In this embodiment, the suction cup 122 is electrically connected to the control unit 110, and its suction force can be adjusted by the control unit 110. When it is necessary to transport the meter head 20 to the meter head clamp 140, the suction cup 122 can be adsorbed onto the glass at the top of the meter head 20 and the suction force can be increased to fix the meter head 20 on the suction cup 122; after the accuracy adjustment is completed, the robotic arm 120 can use the suction cup 122 to remove the meter head 20 from the meter head clamp 140 and transport the meter head 20 to the storage area.

[0032] In one embodiment, the gripper 121 includes a first gripper 1211 and a second gripper 1212 symmetrically arranged; a first clamping portion 141 and a second clamping portion 142 are respectively provided on both sides of the meter clamp 140; the first gripper 1211 and the second gripper 1212 can abut against the meter clamp 140 from both sides of the meter clamp 140 respectively, and the first gripper 1211 and the second gripper 1212 can respectively engage with the first clamping portion 141 and the second clamping portion 142.

[0033] In this embodiment, the first jaw 1211 and the second jaw 1212 can be respectively engaged in the first clamping part 141 and the second clamping part 142 to achieve a stable clamping of the watch head clamp 140. The first clamping part 141 and the second clamping part 142 can be groove structures adapted to the first jaw 1211 and the second jaw 1212 respectively.

[0034] This invention also provides a method for adjusting the timekeeping accuracy of a watch head, which is applied in the aforementioned watch head timekeeping accuracy adjustment system 10. The method includes the following steps S110-S160:

[0035] S110 The control unit acquires the polarization data and instantaneous daily rate data of the meter through the sensing device.

[0036] The sensor 130 can directly acquire the polarization data and instantaneous daily rate data from the meter 20, and then send them to the control unit 110. The control unit 110 then specifies a corresponding strategy for accuracy adjustment based on the polarization data and instantaneous daily rate data.

[0037] In one embodiment, step S110 may specifically include:

[0038] S111. The control unit drives the meter head to rotate to one of the preset meter head postures in the preset meter head posture combination through the robotic arm, and takes the preset meter head posture as the current preset meter head posture.

[0039] S112. The control unit obtains the current polarization data and the current instantaneous daily range data corresponding to the current preset meter head posture through the sensing device;

[0040] S113. The control unit determines whether each preset meter attitude in the preset meter attitude combination has acquired the corresponding current polarization data and current instantaneous daily deviation data; if yes, execute step S115; if no, execute step S114.

[0041] This continues until each preset meter head posture in the preset meter head posture combination has acquired the corresponding current polarization data and the current instantaneous daily deviation data.

[0042] S114. The control unit drives the meter head to rotate to the next preset meter head posture in the preset meter head posture combination through the robotic arm, updates the next preset meter head posture to the current preset meter head posture, and returns to the execution step S112.

[0043] S115. The control unit determines the polarization data and the instantaneous daily deviation data based on the current polarization data and the current instantaneous daily deviation data corresponding to each preset meter attitude.

[0044] In this embodiment, the control unit 110 has pre-set each preset meter head posture in the preset meter head posture combination. Since the current polarization data and current instantaneous daily range data of the meter head 20 will have slight differences when it is in different postures, the current polarization data and current instantaneous daily range data corresponding to each preset meter head posture will change with different preset meter head postures. Therefore, after collecting the current polarization data and current instantaneous daily range data corresponding to each preset meter head posture, it is necessary to perform centralized processing on each current polarization data and each current instantaneous daily range data. For example, the average value of each current polarization data can be calculated to obtain polarization data, and the average value of each current instantaneous daily range data can be calculated to obtain instantaneous daily range data.

[0045] Regarding the speed of instantaneous daily difference data, different preset header postures may result in different trends in the current instantaneous daily difference data. Some current instantaneous daily difference data may be too fast, while others may be too slow. In this case, an instantaneous daily difference tolerance range needs to be set in the control unit 110. This tolerance range is the range of differences between various current instantaneous daily difference data. If the difference between a certain current instantaneous daily difference data and all other current instantaneous daily difference data exceeds the tolerance range, it can be determined that the current instantaneous daily difference data has a large error, and the accuracy of the header 20 also has a large error. In this case, adjustments need to be made based on the current instantaneous daily difference data, i.e., the current instantaneous daily difference data is used as the basis for calculating the instantaneous daily difference data. If the differences between the current instantaneous daily difference data corresponding to all preset header postures do not exceed the tolerance range, the instantaneous daily difference data of the header 20 can be determined as qualified data.

[0046] S120: The control unit determines whether there is any adjustable non-compliant data in the polarization data and the instantaneous daily range data; if yes, then proceed to step S130; if no, then proceed to the following steps S210-S230:

[0047] S210. The control unit determines whether the polarization data is unacceptable data that cannot be adjusted; if yes, proceed to step S220; if no, proceed to step S230.

[0048] S220. The header is determined to be an unqualified header.

[0049] S230. Determine that the header is a qualified header.

[0050] Among them, unadjustable non-compliant data refers to non-compliant data that exceeds the adjustable range. Since the adjustable range of polarization data and instantaneous daily rate data in the mechanical structure is limited, some non-compliant polarization data or instantaneous daily rate data cannot be transformed into compliant data through adjustment of the adjusting body 160. Because adjustment requires the adjusting body 160 to move the movement 210 at a certain angle and distance, if the control unit 110 and the robotic arm 120 cannot drive the movement 210 to achieve a certain angle and distance relative to the adjusting body 160, or if the polarization data or instantaneous daily rate data exceeds the preset adjustable range in the control unit 110, then the non-compliant data will be judged as unadjustable non-compliant data. Therefore, if adjustable non-compliant data exists, precision adjustment is necessary; if unadjustable data exists, adjustment is not possible; if neither exists, it represents compliant data.

[0051] S130, The control unit adjusts the posture of the watch head through the robotic arm and exposes the position where the adjustment body in the movement can be inserted.

[0052] Due to the varying angles at which the movement 210 is positioned, it will rotate, affecting the insertion of the adjusting body 160. Therefore, the orientation of the watch head 20 needs to be adjusted to allow the movement 210 to move and expose the insertion position of the adjusting body 160 within it. This insertion position is where the automatic hammer 211 is not obstructed, and the outer stud 212 and the regulator 213 must be exposed in this position.

[0053] In one embodiment, the mechanism 210 includes an automatic hammer 211, an outer stud 212, and a speed control needle 213; the automatic hammer 211, the outer stud 212, and the speed control needle 213 are all rotatably disposed inside the mechanism 210; when the automatic hammer 211 rotates in the direction of gravity under the action of gravity, the automatic hammer 211 may be directly opposite the outer stud 212 and the speed control needle 213 and located between the outer stud 212 and the speed control needle 213 and the adjusting body 160, or it may be offset from the outer stud 212 and the speed control needle 213 so that the outer stud 211... 2. The speed regulator 213 is directly opposite the adjusting body 160; the adjusting body 160 can abut against one side of the outer stud 212 or one side of the speed regulator 213; when the meter head 20 is driven by the robotic arm 120 and moves relative to the adjusting body 160, the outer stud 212 or the speed regulator 213 is driven to rotate by the adjusting body 160 to adjust the timekeeping accuracy; wherein, the outer stud 212 is used to adjust the polarization data; the speed regulator 213 is used to adjust the instantaneous daily deviation data; at this time, step S130 may specifically include steps S131-S135:

[0054] S131. The control unit drives the meter head to rotate through the robotic arm, so that the plane corresponding to the meter head forms a first angle with the ground.

[0055] S132. The control unit acquires a second movement image of the movement through the side camera, and determines the position of the automatic hammer based on the second movement image.

[0056] S133. The control unit determines whether the outer pile and the speed needle are blocked by the automatic hammer; if not, proceed to step S135; if yes, proceed to step S134.

[0057] S134. The control unit drives the meter head to rotate around the central axis of the meter head through the robotic arm to change the position of the automatic hammer, and then returns to the execution step S132.

[0058] S135. The control unit determines whether the position of the automatic hammer is below the current direction of gravity. If yes, then step S136 is executed; if no, then step S1367 is executed.

[0059] S136, The control unit uses the robotic arm to maintain the meter head at the first angle to the ground.

[0060] S137. The control unit drives the meter head to rotate via the robotic arm to adjust the first included angle, and then returns to step S132.

[0061] In this embodiment, the control unit 110 can control the robotic arm 120 to rotate the watch head 20. In the initial state, the plane corresponding to the watch head 20 is horizontal with the ground, and the automatic hammer 211 remains horizontal and will not rotate due to gravity. When the watch head 20 rotates to form a first angle with the ground, the automatic hammer 211 will rotate clockwise or counterclockwise under the action of gravity, and thus, the part of it that obstructs other components inside the movement 210 will also change. The second movement image includes the overall shape information of the movement 210, and the control unit 110 can identify and determine the position of the automatic hammer 211, the outer stud 212, and the regulator 213 based on the second movement image. If the outer stud 212 and the regulator 213 are not identified, or only one of them is identified, it means that the automatic hammer 211 has not rotated to the correct position, and the watch head 20 needs to be rotated around its own central axis to change the position of the automatic hammer 211. When the automatic hammer 211 is positioned below the current direction of gravity, it hangs naturally and will not rotate further. At this point, both the watch head 20 and the movement 210 are stable, and the outer stud 212 and the regulator 213 are exposed. The adjusting body 160 can then insert and adjust the outer stud 212 and the regulator 213. If the automatic hammer 211 is in another position, it may rotate or wobble further. If precision adjustments are made in this case, the further rotation or wobble of the automatic hammer 211 may affect the adjustment accuracy, thus reducing the accuracy. Therefore, further adjustment of the first angle is required to rotate the automatic hammer 211 to below the direction of gravity. Preferably, the outer stud 212 and the regulator 213 should be positioned opposite to the direction of gravity, so that they are fully exposed and the adjusting body 160 can smoothly perform precision adjustments.

The control unit acquires a first movement image of the movement through a side camera, and determines a first insertion position and a second insertion position in the movement corresponding to the adjustment body based on the first movement image, the polarization data, and the instantaneous daily rate data; wherein, the first insertion position is used to adjust the polarization data; and the second insertion position is used to adjust the instantaneous daily rate data.

[0063] The first movement image includes the position information of the outer stud 212 and the position information of the speed regulator 213 at this time. The control unit 110 can determine the first insertion position and the second insertion position according to the position information of the outer stud 212 and the position information of the speed regulator 213, respectively, and determine the relative positional relationship between the first insertion position and the outer stud 212 according to the polarization data, and determine the relative positional relationship between the second insertion position and the speed regulator 213 according to the instantaneous daily difference data.

[0064] In one embodiment, the mechanism 210 includes an automatic hammer 211, an outer stud 212, and a speed control needle 213; the automatic hammer 211, the outer stud 212, and the speed control needle 213 are all rotatably disposed inside the mechanism 210; when the automatic hammer 211 is subjected to gravity and rotates in the direction of gravity, the automatic hammer 211 may be directly opposite the outer stud 212 and the speed control needle 213 and located between the outer stud 212 and the speed control needle 213 and the adjusting body 160, or it may be offset from the outer stud 212 and the speed control needle 213 so that the outer stud 212 and the speed control needle 213 are aligned with the adjusting body 160. The stud 212 and the speed regulator 213 are directly opposite the adjusting body 160; the adjusting body 160 can abut against one side of the stud 212 or one side of the speed regulator 213; when the meter head 20 is driven by the robotic arm 120 and moves relative to the adjusting body 160, the stud 212 or the speed regulator 213 is driven to rotate by the adjusting body 160 to adjust the timekeeping accuracy; wherein, the stud 212 is used to adjust the polarization data; the speed regulator 213 is used to adjust the instantaneous daily deviation data; at this time, step S140 may specifically include the following steps:

[0068] In this embodiment, the second insertion position can be located to the left or right of the speed regulator 213 relative to its second position. If the instantaneous daily rate data is too fast, the adjustment body 160 needs to turn the speed regulator 213 clockwise. In this case, the second insertion position needs to be set to the left of the speed regulator 213 so that the speed regulator 213 can be turned counterclockwise from the left to slow down the instantaneous daily rate data. Conversely, if the instantaneous daily rate data is too slow, the adjustment body 160 needs to turn the speed regulator 213 counterclockwise. In this case, the second insertion position needs to be set to the right of the speed regulator 213 so that the speed regulator 213 can be turned clockwise from the right to speed up the instantaneous daily rate data.

[0069] S150: The control unit determines whether the polarization data is adjustable unqualified data. If yes, steps S160 and S170 are executed sequentially; if no, step S170 is executed.

[0070] Since the non-compliant data in the polarization data and instantaneous daily deviation data cannot be determined at this time, it is necessary to determine whether the polarization data and instantaneous daily deviation data are adjustable non-compliant data.

[0071] S160. The control unit moves the movement closer to the adjustment body via the robotic arm so that the adjustment body enters the first insertion position, and drives the movement of the movement relative to the adjustment body via the robotic arm according to the first adjustment strategy so that the adjustment body adjusts the polarization data of the movement.

[0072] The first adjustment strategy involves the robotic arm 120 driving the mechanism 210 to move a distance or angle equivalent to the adjusting body 160, in order to make precise adjustments to the external pile 212.

[0073] In one embodiment, step S160 may specifically include the following steps:

[0075] The control unit uses the robotic arm to align the first insertion position in the movement with the adjusting body, and moves the movement closer to the adjusting body so that the adjusting body enters the first insertion position.

[0076] According to the first adjustment strategy, the control unit drives the mechanism to move relative to the adjustment body via the robotic arm, so that the adjustment body moves the outer stake.

[0077] In this embodiment, the control unit 110 drives the outer pile 212 to move a certain distance or angle relative to the adjusting body 160 via the robotic arm 120. This distance or angle is determined based on the difference between the polarization data and the preset standard polarization data.

[0078] S170. The control unit determines whether the polarization data is adjustable unqualified data. If yes, step S180 is executed; if no, step S190 is executed.

[0079] After the polarization data is adjusted, the control unit 110 also needs to determine whether there are any unqualified data that can be adjusted in the instantaneous daily deviation data, so as to adjust the instantaneous daily deviation data.

The control unit moves the movement closer to the adjustment body via the robotic arm so that the adjustment body enters the second insertion position, and drives the movement relative to the adjustment body via the robotic arm according to the second adjustment strategy so that the adjustment body adjusts the instantaneous daily rate data of the movement.

[0081] The first adjustment strategy involves the robotic arm 120 driving the movement 210, equivalent to the adjustment body 160, to move a certain distance or angle in order to make precise adjustments to the speed regulator 213.

[0082] In one embodiment, step S180 may specifically include the following steps:

[0083] The control unit determines a second adjustment strategy based on the speed of the instantaneous daily variation data.

[0084] The control unit uses the robotic arm to align the second insertion position in the movement with the adjusting body, and moves the movement closer to the adjusting body so that the adjusting body enters the second insertion position.

[0085] According to the second adjustment strategy, the control unit drives the movement relative to the adjustment body via the robotic arm, so that the adjustment body moves the speed dial.

[0086] In this embodiment, the control unit 110 uses the robotic arm 120 to move the outer stake 212 a certain distance or angle relative to the adjusting body 160. This distance or angle is determined based on the magnitude of the instantaneous daily deviation data. Ideally, the instantaneous daily deviation data should be close to 0 to best approximate the standard time.

[0087] S190, The control unit determines that the polarization data and the instantaneous diurnal variation data have been adjusted.

[0088] After the adjustment is completed, the control unit 110 can execute step S110 again through the sensing device 130. If it is found that the adjustment is not in place, steps S120-S180 are executed again.

[0089] As can be seen, the sensing device 130 in the watch head 20 timekeeping accuracy adjustment system 10 provided in this embodiment of the invention can obtain the current polarization data and instantaneous daily rate data of the watch head 20 and transmit them to the control unit 110. The control unit 110 can clamp the watch head 20 and the watch head clamp 140 through the robotic arm 120, exposing the movement 210 in the watch head 20. Then, the movement 210 is moved to the fixed adjustment body 160 and the adjustment body 160 is inserted into the first insertion position or the second insertion position in the movement 210 for adjusting accuracy. Then, according to the first adjustment strategy or the second adjustment strategy, the movement 210 is moved relative to the adjustment body 160 so that the adjustment body 160 adjusts the polarization data and instantaneous daily rate data of the watch head 20. This adjustment system and adjustment method can realize automatic analysis and automatic adjustment of polarization data and instantaneous daily rate data, which greatly improves the efficiency and accuracy of watch accuracy adjustment.
