A method for calibrating the start and alarm points of clocks and watches

Abstract

The invention relates to the technical field of clocks, in particular to a method for calibrating an alarm staring point of a clock. The method for calibrating the alarm staring point of the clock comprises the following steps that a motor is started, wherein an output shaft of the motor drives a hand setting bar on a clock movement to rotate in the direction for adjustment; whether the output endof a signal collector outputs an electrical signal or not is judged, wherein the input end of the signal collector is separately electrically connected with a first metal guide piece and a second metal guide piece which are positioned in the clock movement, and the electrical signal is generated by the electrical contact between the first metal guide piece and the second metal guide piece; and ifso, the motor is stopped. The traditional manual operation is replaced with a way that the motor drives the hand setting bar on the clock movement to rotate so as to achieve the purpose of improvingthe working efficiency. Whether the hand setting bar is adjusted to a calibration point or not is judged by the way of the electrical signal. Once the hand setting bar is adjusted to the calibration point, the first metal guide piece and the second metal guide piece are electrically connected to generate the electrical signal on the signal collector so as to control the motor to stop, intelligentadjustment is achieved, and meanwhile, objective accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of clocks and watches, in particular to a method for calibrating the alarm point of a clock. Background technique [0002] Clocks and watches are mainly divided into two categories, one is electronic clocks and watches, which is a kind of timer powered by electric energy, liquid crystal display digital and quartz pointer; The energy is released as power to drive a series of gears to rotate, the speed of the gear train is adjusted by the escapement governor, and the pointer indicates the time and the timer for measuring time. [0003] Before leaving the factory, clocks and watches need to be equipped with needles. During the operation of needles, it is necessary to calibrate the start and alarm points of the clock without installing needles. When the clock is adjusted to the calibration point, the calibration process is completed. Pointer loaded. However, manual work is used in the above-mentioned needle lo...

Problems solved by technology

However, manual work is used in the above-mentioned needle loading operation, and the work efficiency is extremely low, and each operator’s judgment standard is affected by subjective factors, so the objective accuracy cannot be guaranteed, and the accuracy is often low. Slow adjustment thus affects work efficiency
