The core of quartz crystal sensor of quartz clock core is the sensing element piezoelectric quartz crystal. Its principle is the piezoelectric effect, that is, after the quartz crystal is subjected to mechanical stress in some direction, it produces electric dipole. On the contrary, if the voltage is applied in a certain direction of quartz, the deformation will occur in its particular direction. This phenomenon is a phenomenon. It is called the reverse piezoelectric effect. If an alternating electric field is applied to the quartz crystal, the crystal lattice will produce mechanical vibration. When the frequency of the applied electric field is in accordance with the inherent oscillation frequency of the crystal, the resonance of the crystal appears. Because the intensity of the electric field produced by the quartz crystal under pressure is very small, the deformation can be produced by only a very weak external electric field, which makes the piezoelectric quartz crystal very easy to resonate under the excitation of the applied alternating electric field. Its oscillating energy loss is small and the oscillating frequency is very stable. In addition to the excellent mechanical, electrical and chemical stability of quartz, it has become a frequency reference element related to the digital circuit since 40s.
A hair bar is a part that provides energy for a watch. The circle is circled in a box. Use the milling square slot on the shaft to tighten the hair. The square groove of the bar shaft is driven by the upper bar mechanism. The watch can travel for about 36 to 50 hours without rewinding. Because clockwork is subjected to obvious stress, it often causes fracture. Therefore, alloy material is used at present to make the spring almost break free. The clockwork stores certain energy to distribute evenly to the oscillator. To this end, the energy provided by the wheel train group increases the number of cycles by reducing the transmission force in the same proportion. The wheel set consists of 4 wheels and 4 gears, and the latter 3 wheels are riveted on the front 3 gears. In the schematic diagram, the diagonal line represents the engagement between the moving parts, while the transverse line indicates that the riveting is on the same axis. The first wheel is a box wheel with a circumferential milling tooth. The last wheel is the escapement gear, and the escapement wheel is riveted on the gear. The escapement wheel belongs to the distribution mechanism and counter. The box turns around for about 6 hours. During this period, the escapement gear and the escapement wheel rotate about 3600 times. This figure represents the rotation frequency ratio between the first wheel and the last wheel. The ratio is always within this numerical range. Usually try to make the gear and sub wheels in the center of the watch and turn around every hour.
add electricity on the crystal sheet in the quartz clock movement, and the crystal will vibrate correctly at the number of 32768 Hertz waves; then the frequency must be converted to the number of signal currents of the 1Hz (one second of the current). Add the amplitude of some signals (because the current caused by vibration is very weak), followed by some signal current to start the rotor gear, the second hand on the table will be started, then the needle, the time pin is related to the mechanical structure of the principle, such as: the second pin 60, the needle will jump.
All quartz clock movement are equipped with a battery. It provides energy for an integrated circuit and a quartz resonator, vibrating 32768 times per second. And it's faster than that. The integrated circuit is the "brain" of the table. It controls the vibration of quartz resonators and acts as a divider. The 32768 vibration is segmented 15 times to achieve one pulse per second. With one second, the raw material of this time can drive the monitor.
