Title:
DEVICE FOR DETECTING SERVICE LIFE OF ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2019/213994
Kind Code:
A1
Abstract:
Disclosed is a device for detecting the service life of an electronic component (3), the device comprising a workbench (1), a detection module, a piezoelectric ceramic drive power source (8), an alternating-current power source module and a counting module. The detection module comprises a piezoelectric ceramic driver (2) and two identical detection circuits connected in parallel at two ends of the alternating-current power source module. The detection circuits are connected in series via the electronic component (3) and reset switches (9). The reset switches (9) are respectively located on two sides of a metal sheet (203) in the piezoelectric ceramic driver (2), the piezoelectric ceramic driver (2) is electrically connected to the piezoelectric ceramic drive power source (8), and the piezoelectric ceramic drive power source (8) generates an alternating electric field to make the metal sheet (203) produce vibration and deformation so that the reset switch (9) located on the side, generating vibration and deformation, of the metal sheet (203) is closed. The counting module is used to obtain the service life of the electronic component (3). The device can detect the service life of the electronic component (3) under different switch on/off frequencies and can also detect the service life of the component (3) in a frequent switch-on state.
