Abstract
The utility model discloses a printed circuit board vibration test device. The device aims to enable amplitude adjustment at any time in the test process. The device comprises a fixing base plate, an installation plate for fixing a motor, a damping spring, a support rod for holding a circuit board, and a power unit for driving the installation plate to vibrate. The power unit is a controller for controlling the rotating speeds of an eccentric motor and a control motor. The eccentric motor is directly fixedly connected to the installation plate. The installation plate is fixedly connected to the support rod. The motor rotates to drive the installation plate and the support rod to vibrate. Since the motor installation plate is slidingly connected to a fixing rod, the installation plate enables up-down free motion. The damping spring supports and is disposed between the motor installation plate and a vertical rod, so that the whole test deice is prevented from vibrating, the amplitude is adjusted at any time, then the test results are closer to the on-site environments, and reliability of the test results is improved. Since the device is simple in structure, convenient in usage and low in cost, and enables batch manufacturing and usage, production efficiency is greatly improved.
