The invention provides a watch antimagnetic performance detection device. The watch antimagnetic performance detection device comprises a control device, wherein the control device is provided with a controller; a magnetizing device, wherein the magnetizing device comprises a magnetizing coil and a first installation shaft, the magnetizing coil is installed on the first installation shaft, the magnetizing coil is capable of rotating 360 degrees around the first installation shaft, the magnetizing coil is electrically connected with the controller, and a magnetic field is generated when the magnetizing coil is powered; and a pallet device, wherein the pallet device comprises a placing disk and a support, the support is installed in the first installation shaft, the placing disk is installed on the support, the placing disk is used for holding a watch and is capable of rotating 360 degrees relative to the support, the placing disk is arranged at the middle region of the magnetizing coil, and the magnetic field covers the displacing disk. After the placing disk and the magnetizing coil rotate, the controller controls the magnetizing coil to generate the magnetic field. By randomly adjusting the rotation angle of the magnetizing coil and the rotation angle of the placing disk, comprehensive antimagnetic performance data of the watch can be obtained, the measurement accuracy is ensured, an error is reduced, and the performance of the watch is ensured.
Description
technical field [0001] The invention relates to the field of detection equipment, in particular to a detection equipment for the antimagnetic performance of a watch. Background technique [0002] At present, watches, especially analog quartz watches, are easily affected by the magnetic field, resulting in the phenomenon of stopping the watch. According to the characteristics of the magnetic field, the external magnetic field will strengthen or cancel the original magnetic field. Since the pointer quartz watch is realized by a stepping motor, the rotor of the stepping motor is made of magnetic steel, and the stator is made of soft magnetic material. in reverse. The superposition effect is most obvious when the direction of the magnetic field generated by the coil is consistent with the direction of the applied magnetic field. Therefore, considering the direction of the applied magnetic field, it has a greater impact on analog quartz watches. [0003] Therefore, in the rese...
