Description

  The present invention relates to an automatic mainspring winding device for a mechanical wristwatch.

A so-called automatic mainspring winding device is a device for automatically winding a mainspring on a mechanical wristwatch.
Since the mechanical watch automatically achieves the mainspring winding and power generation by the movement of the user's hand, the automatic mainspring winding device is replaced with the movement of the user's hand with a specific operation method. It is something to wind.

  As in the US patent US6254270, the prior art of the automatic mainspring winding device includes a storage box, which includes a partition plate inside, and a motor is fixed to the partition plate. The output shaft of the motor passes through the septum and is coupled to the rotating seat, which provides a space for stereotaxic storage in the mechanical wristwatch. When the mechanical wristwatch is positioned on the rotating seat, the motor is started and the rotating seat is rotated, the purpose of the automatic mainspring winding is achieved for the mechanical wristwatch.

The mainspring winding device similar to the above-mentioned prior art can set the operation time of the mainspring winding by itself according to the necessity of the mainspring winding of the user's mechanical wristwatch. For example, the mainspring winding device can be set to 20 minutes or 30 minutes. Winding the mainspring of a mechanical wristwatch continuously in time, the purpose of the mainspring is achieved.
However, the rotational speed of the motor of the mainspring winding device can be influenced by voltage instability, and the rotational speed cannot always be maintained at a constant speed. It cannot be controlled, and a problem of insufficient winding or excessive winding of the mechanical wristwatch tends to occur.

  In addition, the vibration problem during the operation of the mainspring winding device can lead to damage to the wristwatch or the mainspring winding device itself, or when the rotating seat of the mainspring winding device encounters an external force that is contrary to the driving direction, the motor and its reduction mechanism Is damaged, so how to prevent such problems is not described in the prior art.

  This proposal presents an automatic winding device for mechanical watches.

  It is a type of automatic mainspring winding device, which has an interface for inputting the number of mainspring windings and the direction of rotation required by the mechanical wristwatch to the user, and a transmission device for the mainspring winding device according to a command input by the user. And a control unit that drives the rotating seat to which the mechanical wristwatch is attached a predetermined number of times.

  The purpose of this plan is to rotate the mainspring of the mechanical wristwatch with the planned direction and the planned number of rotations according to the user's setting, to achieve the purpose of the mainspring winding of the mechanical wristwatch, and the problem of insufficient or excessive spring winding Is to provide a watch mainspring winding device.

  The next purpose of this proposal is to provide the mainspring winding device with a function to relax the resonance, to reduce the operating noise of the mainspring winding device, and to reduce the transmission of seismic power to the mechanical wristwatch during the mainspring winding due to the resonance of the device. It is the provision of a watch mainspring winding device that reduces the probability of mechanical watches being damaged by vibration.

  Another object of the present plan is to provide an anti-vibration cushion structure for protecting the power unit, and the anti-vibration cushion structure further protects the reduction gear of the power unit, which is reversely rotated or improperly operated by an improper external force. The present invention provides a watch mainspring winding device that avoids the problem that rotation is accelerated by an external force.

  A further object of the present plan is to control the number of turns of the mainspring of the watch with a control unit, stop the operation when it reaches a sufficient number of rotations, the mechanical wristwatch is effectively wound, and the mainspring is insufficiently wound or the mainspring is wound. It is the provision of a watch mainspring winding device that avoids excessive problems.

  The mainspring winding device described in the prior art calculates the mainspring winding time, for example, if the motor runs continuously for 20 or 30 minutes, the mainspring winding device continuously moves the mechanical wristwatch within this time, When the motor is continuously operated within this time, the rotational speed is changed due to the voltage difference, which may cause a problem of excessive or insufficient number of mainspring windings within the set time. However, since the mainspring winding device of the present invention calculates the number of times of mainspring winding, it cannot stop until the sufficient number of times of operation is reached, and the problem of insufficient mainspring winding or excessive winding of the mainspring can be avoided.

It is a three-dimensional exploded view of the transmission of the mainspring winding device of the present plan. It is a combination external view of the transmission device of the mainspring winding device of the present plan. It is a block diagram of the control module of the mainspring winding device of this proposal. It is a top view of the user interface of this plan. FIG. 3 is a schematic diagram of a usage state of a user interface of the present plan. FIG. 3 is a schematic diagram 2 of a usage state of a user interface of the present plan.

As shown in FIGS. 1 and 2, the mainspring winding device of the present watch includes the following.
The box 50 includes an inclined partition plate 51, and the partition plate 51 divides the box 50 into an internal space 52 and an external space 53. The box 50 further includes a lid 55 that can be opened. When the lid 55 closes the box 50, the external space 53 can be shielded.

  The transmission device 10 is fixed to the inner side 511 of the partition plate 51 and located in the inner space 52. The power shaft 101 of the transmission device 10 penetrates the partition plate 51 and is exposed to the external space 53.

  The rotary seat 11, which is connected to the power shaft 101 of the transmission device 10, is located in the external space 53, and a mechanical wristwatch (not shown in the drawing) is attached to the rotary seat 11.

  The sensor 12, which is installed at a fixed position relative to the transmission 10, is used to detect the number of rotations of the power shaft 101 of the transmission 10 or the number of rotations of the output shaft 105 of the reduction gear box 103 of the transmission 10. . The sensor 12 is realized by a well-known optical encoder.

  A user interface 20, which includes a display unit 21 and a command input unit 25, is provided at a convenient location for viewing and operation by the user on the surface of the box 50.

  As shown in FIGS. 3 and 4, the transmission 10 is fixed to the partition plate 51 by a base 13. An elastic sheet 14 is provided between the relative contact portions of the base 13 and the partition plate 51. When the transmission device 10 starts rotating, the elastic sheet 14 exhibits a vibration-proof function, reduces the vibration force transmitted to the separation plate 51 by the transmission device 10, and further reduces the resonance frequency of the entire box 50, The operation noise of the mainspring winding device can be reduced, and the vibration force transmitted to the wristwatch by the resonance of the box 50 is reduced, and the probability that the wristwatch is damaged by the vibration is reduced.

  The transmission device 10 causes a motor 102 to generate a predetermined rotational speed on the power shaft 101 through a reduction gear box 103, and drives and rotates a rotating seat 11 connected thereto. A soft elastic anti-vibration cover 104 is attached to the outside of the reduction gear box 103, and the anti-vibration cover 104 is positioned inside the base seat 13 and closely attached to the inner wall of the base seat 13. A soft elastic shaft cover 106 is attached to the outside of the output shaft 105 of the reduction gear box 103, and the shaft cover 106 has a polygonal outer wall, which is connected to the polygonal hole 107 of the connecting shaft portion 108 of the power shaft 101. And is closely attached to the inner wall of the connecting shaft portion 108. Since the anti-vibration cover 104 has the effect of anti-vibration and cushioning, it is possible to avoid the operation vibration of the motor 102 or the operation vibration of the rotary seat 11 from affecting the precision gear inside the reduction gear box 103. The shaft cover 106 tightly couples the output shaft 105 and the power shaft 101. Therefore, the output shaft 105 reliably moves and rotates the power shaft 101, causing the output shaft 105 to idle and causing uncertain rotation of the power shaft 101. Thus, it is ensured that the expected number of rotations of the rotary seat connected to the power shaft 101 is reached. However, the user applies an inappropriate torsional external force to the rotating seat 11 and rotates it in the direction opposite to the rotation direction of the output shaft 105, or applies the torsional external force in the same direction as the rotation direction of the output shaft 105. When rotating in acceleration, the power shaft 101 rotates around the shaft cover 106 with the interlocking shaft 108 and has a blocking force on the rotation. Based on this, the undue torsional external force is not transmitted to the output shaft 105, so that the precision gear inside the reduction gear box 103 can be protected.

  Here, the user interface 20 will be described with reference to FIGS. 5 and 6 again. The display unit 21 of the user interface 20 mainly represents information such as the number of rotations of the rotating seat 11 (or the remaining number of unexecuted rotations) and the rotation direction. The number of rotations is displayed as a number, and the rotation direction is displayed as a figure. The command input unit 25 is composed of some push buttons, which are mainly used by a user to input commands such as the number of rotations and the rotation direction.

  The control unit 30, which is coupled to the user interface 20 and the transmission device 10, receives and processes the command input from the command input unit 25, and rotates the power shaft 101 of the transmission device 10 in a predetermined direction according to the command. The sensor 12 is controlled to receive and process the number-of-times signal sensed. When the number of rotations of the rotating seat 11 reaches a certain value, it is determined that the transmission 10 is stopped. The control unit 30 further displays on the display unit 21 the number of rotations input by the user and the number of rotations already executed or not yet executed.

  The display unit 21 is a liquid crystal display, and includes a main display area 211, a direction display area 212, a command presentation area 213, and a tense presentation area 214.

  The main display area 211 represents the current time or the number of times the rotating seat 11 has already been rotated (or the remaining number of unexecuted rotations) in an electronic clock “hour: minute” number system. For example: 23:10 indicates that the current time is 23:10. For example: 25:00 indicates that the number of rotations remaining in the rotary seat is 25.

  The direction display area 212 shows a rotation direction with a figure such as a forward rotation code, a reverse rotation code, and a forward / reverse rotation code.

  The command presentation area 213 represents related command characters, for example: REMAIN (remaining number of times), CLOCK (clock), and SETUP (setting). For example: If the main display area 211 represents the current time, the command presentation area 213 represents “CLOCK”. When the main display area 211 indicates the remaining number of rotations, the command presentation area 213 indicates “REMAIN”. When a setting button 254 described below is pressed, the command presentation area 213 indicates “SETUP”.

  The tense presentation area 214 represents AM, PM, 24H.

  The command input unit 25 includes a start button (turn) 251, a switch button (switch) 252, a light button (light) 253, and a setting button (setup) 254.

  The start button 251 is used to start the transmission device 10.

  A switch button 252 controls the remaining number of rotations or the current time of the main display area 211.

  The illumination button 253 controls blinking of the illumination lamp 15 provided in the box 50, and the illumination lamp 15 is used for the illumination of the external space 53.

  When the setting button 254 is pressed, the start button 251 becomes a function selection (mode) button, the switching button 252 becomes an `` increase button (UP) '' that increases the numerical value, and the illumination button 253 decreases the `` decrease button (DOWN) )"become. When the start button 251 is pressed, the hour, minute, tense (AM / PM / 24 hour), number of forward rotations and number of reverse rotations are set in order. Pressing "Increase button (UP)" 252 or "Decrease button (DOWN)" 253 will increase or decrease the value in the selected item.

Further, the operation state of the start button 251 and the mainspring winding device of the present plan will be described.
As shown in FIG. 7, when the start button 251 is pressed once, the positive rotation code of the direction display area 212 is lit, the main display area 211 indicates “the remaining number of rotations”, and the transmission 10 starts to rotate forward. The sensor 12 detects the number of rotations of the rotating seat 11, and when it rotates once, the remaining number of rotations is automatically reduced by 1, and when the value becomes 0, the operation stops. After that, drive once every hour and every 30 minutes, 48 times a day.

  As shown in FIG. 8, when the start button 251 is pressed for the second time, the reverse rotation code of the direction display area 212 is lit, the transmission device 10 starts reverse rotation, and the operation operation, the sensor 12, and the display method are in the upper stage. It is the same as the explanation of.

  When the start button 251 is pressed for the third time, the forward / reverse rotation sign in the direction display area 212 is lit, the transmission 10 starts to rotate forward, and when the remaining number of rotations becomes 0, the operation stops and the next time or 30 minutes When it becomes, reverse rotation is executed.
