This invention discloses a testing device and method for liquid crystal display modules, relating to the field of liquid crystal display module testing technology. The device includes a base, a flipping bracket, a housing, and a testing platform. The testing platform is equipped with a bidirectional clamping device driven by a first motor for automatically clamping the liquid crystal display module for bending resistance testing, and an auxiliary bending mechanism to ensure uniform force distribution. The housing also houses a click-resistance testing mechanism, including an electric hammer, a pressure sensor, and a displacement sensor, for testing the screen's resistance to click pressure. After testing, debris is automatically removed by a multi-stage cleaning mechanism including a scraper and a spray nozzle. When the testing platform flips, the spray nozzle moves closer to the testing platform to improve the cleaning effect. This invention features a high degree of automation, integrating bending resistance testing and click testing, providing accurate testing and thorough cleaning, effectively improving the efficiency and safety of liquid crystal display module mechanical performance testing.
