Problems solved by technology

[0009]1. The table position of the fixed mobile phone cannot be adjusted;
[0010]2. The steel ball falls along the steel pipe and is rubbed by the pipe wall, causing the kinetic energy to decrease and deviate from the original falling track;
[0011]3. It takes time and effort to adjust the impact stroke, which prolongs the test time and cannot improve the test efficiency
[0012]4. The point of focus cannot be arbitrarily selected within the scope of the mobile phone screen, which cannot meet the requirements of the current test standards;
[0013]5. No secondary impact prevention function

Abstract

The invention discloses a steel ball drop test machine. The test machine comprises: a base plate, a support, a steel ball adsorption assembly, a coaming, a fixture assembly, a shielding assembly, an electrical box, an operation box, a first laser light, a photoelectric sensor, a guide rail and a second laser light. By using the above technical scheme, a platform clamping column which is used to fix a mobile phone can be suitable for the mobile phone with different sizes and can be adjusted up and down so as to adapt the mobile phone with different thicknesses. An acting point can be selected arbitrarily in a mobile phone screen scope and an accuracy is in positive or minus 1mm. A second drop prevention assembly is controlled simultaneously by a cylinder and an electromagnet so as to prevent sudden generation of power off or air-cut off. An infrared sensor can perceive the drop of the steel ball and start the second drop prevention assembly.

Description

technical field [0001] The invention relates to a steel ball drop testing machine. Background technique [0002] The steel ball drop test machine simulates the impact of uncertain objects on the mobile phone screen in daily life. Through the simulation of impact, the resistance of the screen part of the mobile phone (including the screen and its display driver part) to external force impact is tested. In recent years, with the development of communication technology and the continuous increase of people's demand for mobile phones, many changes have taken place in the functions, performance and structure of mobile phones. Especially since the advent of the iPhone and its wide application, more and more large-screen mobile phones have appeared on the market to meet the needs of consumers. Due to the gradual increase of mobile phone screens, the reliability test items of mobile phone screens have increased accordingly, and the requirements for test indicators have been contin...
