A smart phone oled curved screen hardness and drop test device

Abstract

The invention discloses a hardness and floor drop testing device for an OLED curved screen of a smart phone. The hardness and floor drop testing device for the OLED curved screen of the smart phone comprises a base, a lifting motor, a lead screw, a lifting plate, a rotating plate, a driving motor and an impact head, wherein the lower end of an output shaft of the lifting motor is connected with the lead screw through a coupler; the lead screw is further in threaded connection with the lifting plate; the upper end of an impact rod is in threaded connection with a matching block; and the lower end of the impact rod is further connected with the impact head. By a principle that an electromagnet produces magnetism after being electrified, clamping arms on two sides are indirectly driven to move towards the middle so as to tightly clamp the smart phone, therefore, smart phones with different lengths can be clamped, universality of the device is improved, the clamping arms can loosen rapidlywhen in a floor drop test, and the device is simple and effective; and after hardness detection is implemented, floor drop test can further be carried out, the detection period is shortened, the height of the lifting plate is adjusted by the lifting motor, therefore, floor drop tests at different heights are realized, and the device is simple and effective.

Description

technical field [0001] The invention relates to a test device, in particular to a hardness and drop test device of an OLED curved screen of a smart phone. Background technique [0002] OLED displays are displays made of organic electroluminescent diodes. Due to the self-luminous organic electroluminescent diode, no backlight, high contrast ratio, thin thickness, wide viewing angle, fast response speed, flexible panels, wide operating temperature range, simple structure and process are excellent characteristics. , is considered to be the next-generation flat-panel display emerging application technology; China's OLED industry has a very broad prospect, and companies in the industry are also trying to accumulate development experience, but the upstream links of the domestic industry chain are weak, and the industry's supporting capabilities are lacking. major developmental barriers. [0003] Developed foreign mobile phone manufacturers, such as Samsung, have applied OLED cur...

AI Technical Summary

Problems solved by technology

[0003] Foreign developed mobile phone manufacturers such as Samsung have already applied OLED curved screens to mobile phones. However, since curved screens are relatively expensive, the hardness of curved screens has become a key factor in evaluating their pros and cons. Existing testing equipment cannot test the hardness Combined with the drop test test, the test procedure is more complicated. At the same time, during the drop test, the mobile phone is often held by hand, and then it does a free fall movement, and the test method is not standardized.
