The invention belongs to the field of stylus testing and particularly discloses a roboticized stylus testing device and method. The device comprises a working table unit, an operation arm arranged onthe working table unit and a clamping testing unit connected with the operation arm. The clamping testing unit comprises a pressure testing mechanism and a function key pressing mechanism connected tothe pressure testing mechanism, the pressure testing mechanism comprises a mounting flange, an outer sleeve, an inner sleeve, a spring, a pressure sensor and a three-claw chuck assembly, and the outer sleeve sleeves the exteriors of the mounting flange and the inner sleeve; the spring and the pressure sensor are arranged in the outer sleeve and located between the mounting flange and the inner sleeve, the spring is arranged at the bottom of the mounting flange and connected with the upper end of the pressure sensor, the lower end of the pressure sensor is connected with the inner sleeve, andthe three-claw chuck assembly is installed at the lower end of the inner sleeve. According to the method, the device is adopted for stylus testing. According to the device, multi-gesture touch controltesting of a stylus can be achieved, and the device has the advantages of being high in automation degree and testing efficiency and the like.
