Description

Technical Field

[0001] This application relates to the technical field of watches, and particularly to a watch automatic needle mounting device and a watch automatic needle mounting method. Background Art

[0002] Currently, many watch assembly manufacturers in China are labor-intensive enterprises, mainly relying on manual assembly with high labor costs. In the watch needle mounting process, the hands of a watch may include an hour hand and a minute hand; or, the hands of a watch may also include an hour hand, a minute hand and a second hand; or, the hands of a watch may further include an hour hand, a minute hand, a second hand and other hands. When using manual assembly, it is time-consuming and laborious, and the stability and reliability of assembly are relatively low.

[0003] Existing automatic needle mounting machines have functions such as automatically mounting the hour hand, minute hand and second hand. Such automatic needle mounting machines are suitable for watches without a calendar. For watches with a calendar, an additional process must be added, that is, manually adjusting the calendar mechanism to make the calendar reach near the date change position, which increases the labor cost and is not suitable for automated production. Summary of the Invention

[0004] In view of this, this application provides a watch automatic needle mounting device and a watch automatic needle mounting method to solve the technical problems of complex manual processes and low automation in the needle mounting of watches with a calendar in the prior art.

[0009] A processor electrically connected to the vision recognition mechanism and the calendar dialing mechanism respectively. The processor is used to obtain the information of the calendar ring and judge whether the calendar ring is in the date change state. The date change state means that the number at the window of the calendar ring changes; the processor is also used to judge to generate a needle mounting instruction when the calendar ring is in the date change state;

[0022] When receiving the driving instruction, the encoder drives the rotating dial head to rotate so as to turn the calendar ring and collects the number of rotations of the rotating dial head, and sends the number of rotations of the rotating dial head to the processor;

[0023] The needle loading mechanism is specifically used for:

[0024] When the needle installation instruction is received, the pointer is installed on the needle shaft of the movement, and the indicating end of the pointer points to the twelve o'clock position.

[0025] In one embodiment, the information of the calendar ring is a number at the window;

[0026] Alternatively, the information of the calendar ring is the rotation angle of the calendar ring.

[0027] The above-mentioned automatic watch needle mounting device fixes the movement through the fixing mechanism, drives the calendar ring to rotate through the calendar setting mechanism, acquires the information of the calendar ring through the visual recognition mechanism, and the processor can obtain the information of the calendar ring and judge whether the calendar ring is in the date change state. Since the processor can generate a needle mounting instruction when the calendar ring is in the date change state, the needle mounting mechanism can mount the pointer on the needle shaft of the movement after receiving the needle mounting instruction. That is to say, the pointer is mounted when the calendar ring is near the date change position, so as to ensure the accuracy of the calendar ring date change during the subsequent use of the watch. In addition, the installation process of the pointer does not require manual adjustment of the rotation of the calendar ring, saving manual processes and improving the automation degree of the watch pointer installation process, thus effectively solving the technical problems of complex manual processes and low automation degree in the prior art when assembling the pointer of a watch with a calendar.

[0028] An embodiment of the second aspect of the present application further provides an automatic watch needle mounting method, which uses the automatic watch needle mounting device as described in any embodiment of the first aspect. The automatic watch needle mounting method includes:

[0029] Fix the movement of the watch component on the fixing mechanism;

[0034] The processor generates a needle mounting instruction when judging that the calendar ring is in the date change state according to the first feature information and the second feature information;

[0035] The needle mounting mechanism receives the needle mounting instruction and mounts the pointer on the needle shaft of the movement.

[0036] In an embodiment, the processor generates a needle mounting instruction when judging that the calendar ring is in the date change state according to the first feature information and the second feature information, including:

[0037] The processor judges whether the number at the window of the calendar ring changes according to the first feature information and the second feature information; if the number changes, it is determined that the calendar ring is in the date change state;

[0038] Alternatively, the processor determines whether the rotation angle of the calendar ring is within a preset angle range according to the first feature information and the second feature information; if the rotation angle of the calendar ring is within the preset angle range, it is determined that the calendar ring is in the date jump state.

[0042] The processor receives the length information of the stem and determines the gear position. The gear positions include the time gear position and the zero gear position.

[0043] If the gear position is the zero gear position, the driving member is used to drive the rotating dial head and the stem to move to the time gear position.

[0044] In one embodiment, after the needle mounting mechanism receives the needle mounting instruction and mounts the pointer on the needle shaft of the movement, the automatic watch needle mounting method further includes:

[0045] The date setting mechanism pushes the stem to the zero gear position. The zero gear position refers to the gear position where the distance between the stem and the dial is the smallest.

[0046] The date setting mechanism releases the stem.

[0047] The fixing mechanism releases the movement.

[0048] In the above automatic watch needle mounting method, the date setting mechanism, the visual recognition mechanism, and the needle mounting mechanism are all connected and cooperate with the processor. The processor can continuously monitor the information of the calendar ring at any time, and then receive and judge the information of the calendar ring, so as to judge whether the calendar ring is in the date jump state, and generate a needle mounting instruction when the calendar ring is in the date jump state. After receiving the needle mounting instruction, the needle mounting mechanism can mount the pointer on the needle shaft of the movement. That is to say, the pointer is mounted when the calendar ring is near the date jump position, so as to ensure the accuracy of the date jump of the calendar ring in the subsequent use of the watch. In addition, the installation process of the pointer does not require manual adjustment of the rotation of the calendar ring, saving manual processes and improving the automation degree of the watch pointer installation process, thus effectively solving the technical problems of complex manual processes and low automation degree in the prior art when assembling the pointer of a watch with a calendar.

[0067] In order to illustrate the technical solutions described in the present application, the following will be described in conjunction with specific drawings and embodiments.

[0068] An embodiment of the first aspect of the present application provides a watch automatic needle - installing device, which is used to install hands on a watch component to automatically assemble the hands of a watch with a calendar function, reduce the process of manual calendar adjustment, and save labor costs.

[0069] Among them, the watch component includes a connected movement, a dial, a stem, and a calendar ring. The dial is installed on the movement, the stem is provided on the periphery of the dial, and the stem can be in different gears to adjust the time and calendar of the watch. Among them, the gear is related to the length of the stem exposed outside the dial. Specifically, when the stem is in the innermost position, it is in the zero gear, that is, when the distance between the stem and the dial is the smallest, it is in the zero gear. At this time, rotating the stem will not adjust the time or calendar; when the stem moves away from the dial to the calendar gear, at this time, rotating the stem can quickly adjust the calendar, but will not adjust the time; when the stem moves away from the dial to the time gear, at this time, rotating the stem can adjust the time, and the calendar can be adjusted by adjusting the time. The calendar ring is annular, and it is provided with numbers for indicating the date. The numbers are evenly spaced and circular. In this embodiment, the numbers on the calendar ring are the monthly calendar, including the numbers 1 to 31.

[0070] Please refer to Figure 1 and Figure 2 , in an embodiment of the present application, the automatic watch needle loading device 100 includes a fixing mechanism 10, a calendar adjusting mechanism 20, a vision recognition mechanism 30, a processor 40, and a needle loading mechanism 50.

[0071] The fixing mechanism 10 is used to fix the movement. It can be understood that the fixing mechanism 10 and the movement can be fixedly connected by detachable connection methods such as clamping, snap connection, or vacuum adsorption, to prevent the movement from shaking easily and affecting the accuracy of the subsequent needle loading process. Specifically, the movement can be connected to the watch case, and the movement is fixed through the fixed connection between the fixing mechanism 10 and the watch case. It can be understood that in other embodiments of the present application, the watch case can also be omitted, and the movement is in direct contact with the fixing mechanism, and the movement is fixedly connected to the fixing mechanism 10, which can also achieve the fixation of the movement, and no limitation is made here.

[0072] The calendar adjusting mechanism 20 is used to rotate the stem to drive the calendar ring to rotate. That is to say, the calendar adjusting mechanism 20 can be connected to the stem to drive the stem to rotate.

[0073] The vision recognition mechanism 30 is disposed opposite to the fixing mechanism 10, and the vision recognition mechanism 30 is used to collect information of the calendar ring. Among them, the vision recognition mechanism 30 includes a CCD camera, which can be used to collect image information of the calendar ring and send it to the processor 40.

[0074] The processor 40 is communicatively connected to the vision recognition mechanism 30, the calendar adjusting mechanism 20, and the needle loading mechanism 50 respectively. The processor 40 is used to obtain the information of the calendar ring and judge whether the calendar ring is in the state of calendar jumping. The state of calendar jumping means that the numbers at the window of the calendar ring change; the processor 40 is also used to judge to generate a needle loading instruction when the calendar ring is in the state of calendar jumping.

[0075] It can be understood that the date jump state refers to the state where the date ring reaches near the date jump position, that is, the date jump state is a state of the date ring within a period of time. The date jump state can include various states in the short time before, during, and after the date jump. For example, within 15 minutes before and 15 minutes after the date jump, the date ring is in the date jump state.

[0076] The window of the date ring refers to the window opened on the dial after the watch is assembled. The wearer can observe a single digit on the date ring through this window. Usually, the window is set at the 3 o'clock or 6 o'clock position of the dial, but it is not limited to this.

[0077] The needle mounting mechanism 50 is used to receive the needle mounting instruction and mount the pointers on the needle shafts of the movement. Specifically, the pointers mounted by the needle mounting mechanism 50 include the hour hand, the minute hand, and the second hand, and the indicating ends of the pointers point to the 12 o'clock position. Among them, the indicating end of the pointer refers to the end of the pointer that is far from the central axis when the pointer makes a circular motion around the central axis. In this way, when the pointers rotate normally for two circles to the 12 o'clock position, the date ring reaches near the date jump position again.

[0078] The above-mentioned automatic watch needle mounting device 100 fixes the movement through the fixing mechanism 10, drives the date ring to rotate through the date setting mechanism 20, acquires the information of the date ring through the vision recognition mechanism 30, and the processor 40 can obtain the information of the date ring and judge whether the date ring is in the date jump state. Since the processor 40 can generate a needle mounting instruction when the date ring is in the date jump state, the needle mounting mechanism 50 can mount the pointers on the needle shafts of the movement after receiving the needle mounting instruction. That is to say, the pointers are mounted when the date ring is near the date jump position, so as to ensure the accuracy of the date jump of the date ring in the subsequent use process of the watch. In addition, the installation process of the pointers does not require manual adjustment of the rotation of the date ring, saving manual processes and improving the automation degree of the process of mounting the pointers on the watch, thus effectively solving the technical problems of complex manual processes and low automation degree in the prior art when assembling the pointers of a watch with a date.

[0079] Among them, the vision recognition mechanism 30 can also be used to identify the information of the watch components 200, pointers, etc.; or, the information of the watch components 200 and pointers, etc. can also be obtained through another set of vision recognition mechanisms, which is not limited here.

[0080] Among them, please refer to Figure 1 and Figure 2, the needle installation mechanism 50 is movably arranged on the fixing mechanism 10, and can be moved to the top of the watch assembly 200 and install the pointer when the calendar ring jumps. Secondly, an observation hole 11 is also opened on the fixing mechanism 10, and the watch automatic needle installation device 100 can also include a detection mechanism arranged at the observation hole 11, and the detection mechanism includes a CCD lens or a magnifying glass, and is used to detect whether the distance between the pointers meets the requirements after the pointers are installed on the watch assembly 200. Specifically, the distance between the pointers refers to the spacing between the pointers in the vertical direction. In addition, the processor 40 can send display information such as information of the calendar ring to the display screen 60, and the display screen 60 displays according to the display information, which can facilitate the operator to observe the needle installation progress and modify parameters in real time.

[0081] In one embodiment of the present application, the information of the calendar ring is the number at the window. Specifically, the visual recognition mechanism 30 collects the information of the calendar ring, which means that the visual recognition mechanism 30 collects the number at the calendar window and sends the collected number at the window to the processor 40. In this way, the information to be collected by the visual recognition mechanism is more intuitive and easy to be observed.

[0082] In other embodiments of the present application, the information of the calendar ring may be other, for example, the information of the calendar ring may be the rotation angle of the calendar ring. In this case, the visual recognition mechanism 30 collects the information of the calendar ring, which means that the visual recognition mechanism 30 collects the position of the designated point on the calendar ring at that moment, and the line between the position of the designated point at that moment and the center of the calendar ring and the line between the position of the designated point at another moment and the center of the calendar ring is the rotation angle of the calendar ring.

[0083] In one embodiment of the present application, the watch assembly 200 further includes a movement transmission member, wherein the crown and the calendar ring can be transmission-connected to the movement transmission member, and the calendar dial mechanism 20 includes a rotating dial head 21 and an encoder.

[0084] The rotating dial head 21 can clamp the crown and drive the crown to rotate so as to turn the date ring through the movement transmission member. The encoder is connected to the rotating dial head 21 and is used to control and identify the number of rotations of the rotating dial head 21. In this way, the number of rotations of the rotating dial head 21 can be accurately controlled through the information input of the encoder. Since the rotating dial head 21 can drive the crown to rotate so as to turn the date ring through the movement transmission member, the rotation of the crown and the date ring can also be accurately controlled.

[0085] Specifically, the movement rotating member includes a plurality of gears that are drivingly connected. A plurality of internal teeth are provided on the inner side of the date ring. Some of the gears are drivingly connected to the stem, and some of the gears are drivingly connected to the date ring. It can be understood that in a common watch, the dial has 12-hour scales. The hour hand rotates one full circle in 12 hours, and two full circles are one day. Correspondingly, when the date ring is moved forward one grid, the effect of changing the date is achieved. In addition, there are watches with 24-hour scales on the dial. The 24-hour hand rotates one full circle in 24 hours, that is, one day. Correspondingly, when the date ring is moved forward one grid, the effect of changing the date is achieved. This application does not make any limitations.

[0086] Further, the date setting mechanism 20 further includes a torque sensor. The torque sensor is used to monitor the torque of the rotating knob 21. It can be understood that if the torque is too large, the rotation speed of the rotating knob 21 is too fast, and the rotation speed of the stem and the rotation speed of the date ring are too fast, which is not conducive to accurately controlling the jumping position of the date ring. If the torque is too small, the rotation speed of the stem and the rotation speed of the date ring are too slow, resulting in low work efficiency. Therefore, when the torque is moderate, the rotation speed of the rotating knob 21 is moderate, and the rotation speed of the stem and the rotation speed of the date ring are moderate, which is convenient for the visual recognition mechanism 30 to accurately control the jumping position of the date ring.

[0087] In an embodiment of the present application, please refer to Figure 1 , the date setting mechanism 20 further includes a driving member 22 connected to the rotating knob 21. The driving member 22 is used to drive the rotating knob 21 to move closer to or away from the dial, so as to change the gear position of the stem. The gear positions include the time gear position and other gear positions. Specifically, the other gear positions include the zero gear position and the date gear position. In this way, when the rotating knob 21 clamps the stem, the stem can also move closer to or away from the dial under the action of the driving member 22, so as to realize the adjustment of the gear position, so that after the needle installation is completed, the stem can be restored from the time gear position to other gear positions.

[0088] In addition, since the relative distance between the stem and the dial is fixed when the stem is in the time gear position or other gear positions, that is, the displacement amount when the stem switches between the time gear position and other gear positions is fixed, the driving member 22 can also be used to control the displacement amount of the rotating knob and the stem, so as to realize the gear position switching of the stem.

[0089] Specifically, the driving member 22 can be a linear driving module such as a driving cylinder or a motor-driven lead screw to realize the linear reciprocating movement of the stem, so as to avoid the stem connected to the stem from being subjected to an external force inclined to the extending direction of the stem, and reduce the possibility of deformation of the stem.

[0090] In one embodiment of the present application, the calendar dial mechanism 20 further includes a push-pull force sensor connected to the driving member 22, and the push-pull force sensor is used to monitor the push or pull force of the driving member 22 to monitor the switching of the time slot and other slots. It can be understood that when the crown is in the time slot or other slots, the relative distance between the crown and the dial is fixed, that is, the displacement of the crown when switching between the time slot and other slots is fixed, and the absolute value of the force required by the driving member 22 to push and pull the dial to drive the crown to move the fixed displacement is constant, therefore, the push-pull force sensor can be used to monitor the switching of the time slot and other slots.

[0091] Optionally, in one embodiment of the present application, the processor 40 is specifically configured to:

[0092] An information collection instruction is sent to the visual recognition mechanism 30 , a driving instruction is sent to the calendar dialing mechanism 20 , and a needle installation instruction is sent to the needle installation mechanism 50 .

[0093] The visual recognition mechanism 30 is specifically used for:

[0094] When the information collection instruction is received, the information of the calendar ring is collected and sent to the processor 40 .

[0095] The calendar mechanism 20 is specifically used for:

[0096] When receiving the driving instruction, the encoder drives the rotating dial head 21 to rotate to turn the calendar ring and collects the number of rotations of the rotating dial head 21, and sends the number of rotations of the rotating dial head 21 to the processor 40. The processor 40 can count the number of rotations of the crown head and the rotation of the calendar ring according to the number of rotations of the rotating dial head 21.

[0097] The needle loading mechanism 50 is specifically used for:

[0098] When receiving the needle installation instruction, a pointer is installed on the needle shaft of the movement, and the indicating end of the pointer points to the twelve o'clock position.

[0099] In this way, the processor 40 can send information collection instructions to the visual recognition mechanism 30, drive instructions to the calendar dialing mechanism 20, and needle installation instructions to the needle installation mechanism 50, and assist the visual recognition mechanism 30, the calendar dialing mechanism 20, and the needle installation mechanism 50 to realize the automation of pointer installation.

[0100] The above-mentioned automatic watch needle installation device 100 fixes the movement through the fixing mechanism 10, drives the calendar ring to rotate through the calendar adjusting mechanism 20, acquires the information of the calendar ring through the vision recognition mechanism 30, and the processor 40 can obtain the information of the calendar ring and judge whether the calendar ring is in the date-changing state. Since the processor 40 can generate a needle installation instruction when the calendar ring is in the date-changing state, the needle installation mechanism 50 can install the pointer on the needle shaft of the movement after receiving the needle installation instruction. That is to say, the pointer is installed when the calendar ring is near the date-changing position, so as to ensure the accuracy of the calendar ring date-changing during the subsequent use of the watch. In addition, the installation process of the pointer does not require manual adjustment of the rotation of the calendar ring, saving manual processes and improving the automation degree of the watch pointer installation process, thus effectively solving the technical problems of complex manual processes and low automation degree in the prior art when assembling the pointer of a watch with a calendar.

[0101] An embodiment of the second aspect of the present application proposes an automatic watch needle installation method, which uses the automatic watch needle installation device in any embodiment of the first aspect. Please refer to Figures 1 to 3 , in an embodiment of the present application, the automatic watch needle installation method includes:

[0102] Step S1, fix the movement of the watch assembly 200 on the fixing mechanism 10.

[0103] Specifically, the movement including the dial is fixed on the fixing mechanism 10 by clamping, snap connection or fixture clamping. Among them, the movement can be connected to the watch case, and the movement is fixed through the fixed connection between the fixing mechanism 10 and the watch case. It can be understood that in other embodiments of the present application, the watch case can also be omitted, and the movement directly contacts the fixing mechanism, and the movement is fixedly connected to the fixing mechanism 10.

[0104] Step S2, clamp the stem of the watch assembly 200 through the calendar adjusting mechanism 20.

[0105] Specifically, the calendar adjusting mechanism 20 includes a rotating dial head 21, and the rotating dial head 21 can clamp the stem of the watch assembly 200.

[0106] Step S3, collect the information of the calendar ring of the watch assembly 200 as the first feature information through the vision recognition mechanism 30, and send the first feature information to the processor 40.

[0107] Specifically, the vision recognition mechanism 30 includes a CCD camera. The vision recognition mechanism 30 can take pictures of the calendar ring and the stem of the watch assembly 200 at the first time point. Then, at the first time point, the information of the calendar ring is the first feature information, and the first feature information is sent to the processor 40 through the vision recognition mechanism 30.

[0108] Step S4, rotate the stem through the calendar adjusting mechanism 20.

[0109] Specifically, when the calendar dial mechanism 20 rotates the crown, the rotation of the crown can be transmitted to the calendar ring through the movement transmission member to dial the calendar ring. The calendar dial mechanism 20 also includes an encoder, and the rotating dial head 21 clamped on the crown rotates and drives the crown to rotate. The encoder can be used to control and identify the number of rotations of the rotating dial head 21, so as to facilitate the subsequent feedback of the number of rotations of the crown to the processor 40.

[0110] Furthermore, the calendar dial mechanism 20 also includes a torque sensor, which is used to monitor the torque of the rotating dial head 21. When the torque is moderate, the rotation speed of the rotating dial head 21 is moderate, and the rotation speed of the crown and the calendar ring is moderate, which is convenient for the subsequent visual recognition mechanism 30 to accurately control the calendar jump position of the calendar ring.

[0111] Step S5 , collecting the information of the calendar ring again as the second characteristic information through the visual recognition mechanism 30 , and sending the second characteristic information to the processor 40 .

[0112] Specifically, the visual recognition mechanism 30 uses a CCD camera to take pictures of the calendar ring and the crown of the watch component 200 at the second time point. At the second time point, the information of the calendar ring is the second characteristic information, and the second characteristic information is sent to the processor 40 through the visual recognition mechanism 30.

[0113] Step S6: The processor 40 generates a needle installation instruction when it determines that the calendar ring is in a calendar skipping state according to the first characteristic information and the second characteristic information.

[0114] Specifically, the processor 40 generates a needle installation instruction and sends it to the needle installation mechanism 50. It can be understood that the visual recognition mechanism 30 is in a normally open state, and between the first time point and the second time point, the visual recognition mechanism 30 continues to recognize the information of the calendar ring of the watch component 200 in real time until the second time point. In other words, before the second time point, the calendar ring rotates a certain angle, but the calendar ring of the watch component 200 recognized by the visual recognition mechanism 30 has not reached the calendar skipping position. It can be understood that the calendar skipping state refers to the calendar ring reaching the vicinity of the calendar skipping position, that is, the calendar skipping state is a state of the calendar ring within a time period, and the calendar skipping state may include a variety of states in a short period of time before the calendar skipping, the calendar skipping, and after the calendar skipping.

[0115] Step S7, receiving the needle installation instruction through the needle installation mechanism 50 and installing the pointer on the needle shaft of the machine core.

[0116] Specifically, the hand installation mechanism 50 installs the hour hand on the movement, and the indicating end of the hand points to the twelve o'clock position.

[0117] Among them, the visual recognition mechanism 30 in step S3 can be normally open, that is, the calendar ring information can be recognized at the moment when the movement to be loaded with needles is fixed on the fixing mechanism 10. Secondly, the recognition of the first characteristic information is not necessarily carried out when the crown is stationary. After the crown is turned, the first characteristic information can be stopped and then recognized. The first characteristic information can also be recognized under the premise that the calendar ring moves slowly so that the visual recognition mechanism 30 can easily recognize it. Therefore, step S3 can be before step S2, or after step S4, or between step S2 and step S4, but step S4 does not exceed step S2.

[0118] In the above-mentioned automatic needle installation method for watches, the calendar dialing mechanism 20, the visual recognition mechanism 30, and the needle installation mechanism 50 are all connected and cooperated with the processor 40. The processor 40 can continuously monitor the information of the calendar ring at any time, and then receive and judge the information of the calendar ring, so as to judge whether the calendar ring is in the calendar skipping state, and generate a needle installation instruction when the calendar ring is in the calendar skipping state. After receiving the needle installation instruction, the needle installation mechanism 50 can install the pointer on the needle shaft of the movement, that is, the pointer is installed when the calendar ring is near the calendar skipping position, so as to ensure the accuracy of the calendar ring jumping in the subsequent use of the watch. In addition, the installation process of the pointer does not require manual adjustment of the rotation of the calendar ring, which saves manual processes and improves the automation degree of the watch pointer installation process, thereby effectively solving the technical problems of complex manual processes and low automation degree when assembling the pointer of a watch with a calendar in the prior art.

[0119] In one embodiment of the present application, in step S6, the processor 40 generates a needle installation instruction when it determines that the calendar ring is in a calendar skipping state according to the first characteristic information and the second characteristic information, including:

[0120] In step S61, the processor 40 determines whether the number in the window of the calendar ring changes according to the first characteristic information and the second characteristic information; if the number changes, it is determined that the calendar ring is in a calendar skipping state.

[0121] Specifically, the processor 40 identifies the number in the window of the calendar ring at the first time point based on the first characteristic information. According to the rule of calendar changes, the number in the window when the calendar ring is in a skipping state at the second time point should change from the number in the window of the calendar ring at the first time point. Then, based on the font characteristic information of the number, that is, the writing method of the number, the processor 40 identifies the writing method of the number in the window of the calendar ring at the second time point based on the second characteristic information. If the number in the window of the calendar ring at the second time point is different from the number in the window of the calendar ring at the first time point, and the difference is 1 or 30, the calendar ring is in a skipping state, that is, at the second time point, the calendar ring of the watch assembly 200 is located near the skipping position.

[0122] It can be understood that in other embodiments of the present application, the method for judging the change of the number at the window of the calendar ring can also be other. For example, the processor 40 identifies the number at the window of the calendar ring at the first time point according to the first feature information, and the processor 40 identifies the number at the window of the calendar ring at the second time point according to the second feature information. If the difference between the number at the window of the calendar ring at the second time point and the number at the window of the calendar ring at the first time point is 1 or 30, the calendar ring is in the state of date jumping, that is, at the second time point, the calendar ring of the watch assembly 200 is located near the date jumping position.

[0123] Alternatively, in step S62, the processor 40 judges whether the rotation angle of the calendar ring is within a preset angle range according to the first feature information and the second feature information; if the rotation angle of the calendar ring is within the preset angle range, it is determined that the calendar ring is in the state of date jumping.

[0124] Specifically, in the first feature information, the number at the window of the calendar ring is the target number, and the position where the target number is located is the first point. In the second feature information, the position where the target number is located is the second point. If the included angle between the line connecting the first point and the center of the calendar ring and the line connecting the second point and the center of the calendar ring is equal to the preset angle, the calendar ring is in the state of date jumping, that is, at the second time point, the calendar ring of the watch assembly 200 is located near the date jumping position. Among them, the preset angle range is 10° to 12°.

[0125] Both of the above two methods for judging that the calendar ring is in the state of date jumping can quickly identify whether the calendar ring reaches near the date jumping position during the rotation process, and either method can be selected for identification according to the watch assembly 200 designed with different movements, with strong applicability.

[0126] Please refer to Figure 1 and Figure 3 , in an embodiment of the present application, the date setting mechanism 20 includes a rotating dial head 21 and a driving member 22. Step S2, clamping the stem of the watch assembly 200 through the date setting mechanism 20 includes:

[0127] Step S21, clamping the stem through the rotating dial head 21.

[0128] Step S22, the visual recognition mechanism 30 recognizes the length information of the stem and sends the length information of the stem to the processor 40. The length information of the stem refers to the length value of the stem exposed outside the dial.

[0129] Step S23, the processor 40 receives the length information of the stem and judges the gear position. The gear positions include the time gear position and other gear positions;

[0130] If the gear position is other gear positions, the driving member 22 drives the rotating dial head 21 and the stem to move to the time gear position.

[0131] Specifically, the processor 40 receives the length of the stem and determines that the gear position is other than the time gear. The processor 40 sends a displacement instruction to the driving member 22. The driving member 22 receives the displacement instruction and drives the rotating dial head 21 and the stem to move to the time gear.

[0132] Among them, the driving member 22 of the calendar adjusting mechanism 20 is a linear driving module such as a driving cylinder or a motor-driven lead screw to realize the linear reciprocating movement of the stem.

[0133] Optionally, in other embodiments of the present application, the processor 40 receives the length of the stem and determines that the gear position is other than the time gear. The processor 40 sends a pulling force instruction or a pushing force instruction to the driving member 22. The driving member 22 receives the pulling force instruction or the pushing force instruction and moves the stem to the time gear according to the pulling force instruction or the pushing force instruction. In addition, the calendar adjusting mechanism 20 may further include a pulling and pushing force sensor for monitoring the pulling force or the pushing force of the driving member 22 to monitor and feedback the magnitude of the pulling force or the pushing force during the process of moving the stem to the time gear.

[0134] Optionally, in another embodiment of the present application, the driving member 22 can be used to identify and control the displacement amount of the rotating dial head 21 and the stem. When the processor 40 receives the length of the stem and determines that the gear position is other than the time gear, the processor 40 sends a gear shifting instruction to the driving member 22. The driving member 22 receives the gear shifting instruction and controls the displacement amount of the rotating dial head 21 and the stem until it reaches the time gear.

[0135] In this way, regardless of whether the gear position of the stem is the time gear or other gears when the watch assembly 200 comes in, the observation and adjustment of the gear position can be realized through the cooperation of the visual recognition mechanism 30, the processor 40, and the calendar adjusting mechanism 20.

[0136] In an embodiment of the present application, in step S7, after the needle mounting mechanism 50 receives the needle mounting instruction and mounts the pointer on the needle shaft of the movement, the automatic watch needle mounting method further includes:

[0137] Step S8, pushing the stem to the zero gear through the calendar adjusting mechanism 20. The zero gear refers to the gear position where the distance between the stem and the dial is the smallest, that is, the innermost gear position of the stem.

[0138] Specifically, the processor 40 sends a pushing force instruction to the driving member 22. The driving member 22 receives the pushing force instruction and pushes the rotating dial head 21 and the stem to the zero gear according to the pushing force instruction. In addition, the pulling and pushing force sensor is used to monitor the pushing force of the driving member 22 to monitor and feedback the magnitude of the pushing force during the process of pushing the stem to the zero gear.

[0139] Step S9, the calendar adjusting mechanism 20 releases the stem.

[0140] Specifically, the rotating dial head 21 releases the stem.

[0141] Step S10, the fixing mechanism 10 releases the movement.

[0142] Specifically, the watch assembly 200 can be transferred from the fixing mechanism 10 by a moving mechanism such as a manipulator.

[0143] In an embodiment of the present application, the automatic watch needle mounting method includes:

[0144] Step S1, fixing the movement of the watch assembly 200 on the watch fixing mechanism 10.

[0145] Step S2, first, clamping the stem of the watch assembly 200 by the rotating head 21 of the calendar mechanism 20; second, identifying the length of the stem through the vision recognition mechanism 30 and sending the length of the stem to the processor 40, where the length of the stem refers to the length of the stem exposed outside the dial; second, the processor 40 receives the length of the stem and judges the gear position, and the gear positions include the time gear and other gears. If the gear position is other gears, the rotating head 21 and the stem are driven by the driving member 22 to move to the time gear. If the gear position is the time gear, then step S3 is performed. That is to say, according to the arrangement of the assembly production process, if the previous station or process has pushed or pulled the stem to other gears, it is necessary to push or pull the stem to the time gear through the calendar mechanism 20 to facilitate the subsequent steps of dialing the needle and changing the calendar and installing the pointer.

[0146] Step S3, collecting the information of the calendar ring of the watch assembly 200 at the first time point by the vision recognition mechanism 30 as the first characteristic information, and sending the first characteristic information to the processor 40 through the vision recognition mechanism 30.

[0147] Step S4, rotating the stem by the calendar mechanism 20.

[0148] Step S5, collecting the information of the calendar ring of the watch assembly 200 at the second time point by the vision recognition mechanism 30 as the second characteristic information, and sending the second characteristic information to the processor 40 through the vision recognition mechanism 30.

[0149] Step S6, the processor 40 generates a needle mounting instruction when judging that the calendar ring is in the jumping calendar state according to the first characteristic information and the second characteristic information.

[0150] Step S7, the needle mounting mechanism 50 receives the needle mounting instruction and installs the pointer on the needle shaft of the movement.

[0151] Step S8, pushing the stem to the zero gear by the calendar module, where the zero gear refers to the gear position where the stem is at the innermost side.

[0152] Step S9, the calendar mechanism 20 releases the stem.

[0153] Step S10, the fixing mechanism 10 releases the movement.

[0154] In the above-described method for automatically installing watch hands, the date setting mechanism 20, the vision recognition mechanism 30, and the hand installing mechanism 50 are all connected and coordinated with the processor 40. The processor 40 can continuously monitor the information of the calendar ring at any time, receive and judge the information of the calendar ring, so as to judge whether the calendar ring is in the date jumping state, and generate a hand installing instruction when the calendar ring is in the date jumping state. After receiving the hand installing instruction, the hand installing mechanism 50 can install the watch hands on the arbors of the movement. That is to say, the hands are installed when the calendar ring is near the date jumping position, so as to ensure the accuracy of the date jumping of the calendar ring during the subsequent use of the watch. In addition, the installation process of the hands does not require manual adjustment of the rotation of the calendar ring, saving manual processes and improving the automation degree of the watch hand installation process, thus effectively solving the technical problems of complex manual processes and low automation degree in the prior art when assembling the hands of a watch with a calendar.
