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.

This utility model relates to the field of battery performance testing technology and discloses an automatic temperature acquisition and alarm device suitable for large-scale battery testing. It includes a battery body for providing electrical energy, a membrane switch for monitoring contact status fixedly connected to one side of the battery body, adhesive tape for connecting the membrane switch and the battery body fixedly connected to the surface of the membrane switch, and a thermocouple sensor for acquiring the battery surface temperature fixedly connected to the end of the membrane switch away from the battery body. The two sides of the thermocouple sensor are fixedly connected to the adhesive tape on the surface of the membrane switch via the adhesive tape. Through integrated design, the membrane switch, thermocouple sensor, and adhesive tape are collaboratively fixed to the battery body, forming a precise temperature acquisition and contact monitoring system. The adhesive tape uses specific materials and reasonable specifications to ensure stable fixation and electrical safety at high temperatures, solving the problem of temperature acquisition failure caused by traditional fixing methods.
