Abstract

The invention discloses a device and method for detecting the impact effect of a vehicle-mounted liquid crystal screen. The device comprises a control terminal, an ejection impact module, a track, a high-speed camera, a fixing module, a clamping module, a force detection module, and a micro-processing drive unit. The fixing module and the clamping module are used for fixing and clamping a to-be-tested liquid crystal screen; the ejection impact module is used for ejecting a small ball so that the small ball impacts the to-be-tested liquid crystal screen along the track; the control terminal calculates the speed of the small ball, the clamping pressure and the impact force borne by the liquid crystal screen and the fitting of the impact force according to set control parameters and data fed back by the high-speed camera and the force detection module, and various detection results of the impact effect of the liquid crystal screen are obtained. The detection device designed by the invention can generate head-on collision and side pressure tests, realizes automation and intelligence of vehicle-mounted liquid crystal screen detection in combination with a detection method, can accurately generate collision in a specified direction and with force requirements, detects forces in all directions borne by the liquid crystal screen, and can be used for quality detection of the vehicle-mounted liquid crystal screen.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal screen detection, relates to the quality detection of a vehicle-mounted liquid crystal screen, and is a detection device and method for the impact effect of a vehicle-mounted liquid crystal screen. Background technique [0002] The vehicle-mounted LCD screen is an important electronic component used in the central control of the car. Its performance plays a very important role in the safe driving of the car. Therefore, its performance testing is also very important. [0003] When the vehicle-mounted LCD screen is used as the central control of the car, it is combined with the edge frame of the LCD screen through fasteners to form an integral part. When the car is hit, the resulting acceleration will be transmitted to the edge frame of the LCD screen through the fasteners, and then to the LCD screen, forming an impact force. For the LCD screen, the edge of the LCD screen is easy to break or...
