Abstract

The invention discloses an electronic component vibration test workbench, which comprises a housing, an impact cylinder, a support, a spring, a vibration motor, a top plate, a pressing plate and a loading grid. The impact cylinder is cylindrical, two ends of the impact cylinder are provided with a water inlet and a water outlet, the water inlet is provided with a water pump, the water pump is arranged on a side plate at the water inlet, and the water flow injected by the water pump can be adjusted. A bottom plate is installed in the middle of the support, an air cylinder is installed on the bottom plate, and a telescopic rod of the air cylinder is detachably connected with the limiting plate and can be connected with the impact barrel in a clamped mode. And the impact cylinder is supported on the housing through the fixed seat and the spring. And a plurality of vibration motors are arranged on the side plate of the impact cylinder. The pressing plate is matched with the top plate, the number of the carrying grids is multiple, and electronic elements can be placed in the cavity. Various sinusoidal vibration modes are set, vibration can be simulated through the water pump and the impact cylinder by changing the water injection pressure and utilizing irregularity of water flow, other random vibration scenes can also be simulated, and the testing efficiency is high.

Description

technical field [0001] The invention relates to the field of electronic component detection, in particular to an electronic component vibration test workbench. Background technique [0002] Electronic components are basic elements in electronic circuits, usually individually packaged, and have two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with specific functions, such as amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electronic components is to solder them to a printed circuit board. The stability of electronic components is related to the ambient temperature and humidity, and is also affected by vibration, such as automobiles, generator sets, trains, air-conditioning units, etc. The vibration test is to simulate various vibrations encountered by the product in the transportation, installation and use environment Environmental impact, used to determine whether the pr...
