Automated key pressing device having two key pressing modules and a loading stage

An automated key pressing device, comprising:

• a base having a test area for placing a keyboard therein, wherein the keyboard has a plurality of key rows which are parallel to each other;
• a plurality of key pressing modules arranged abreast on the base along a long axis of the base, and respectively extending outwardly into the test area from the base, wherein lengths of the key pressing modules extending into the test area are incrementally increased along a direction respectively for pressing at least different two of the key rows of the keyboard respectively;
• and
• a control unit configured to respectively trigger the key pressing modules to press the keyboard.

An automated key pressing device, comprising:

• a loading stage configured to load a keyboard of an electronic device;
• a base located at one side of the loading stage;
• a transmission module reciprocatedly slidable on the base;
• at least one first key pressing module disposed on the transmission module, and extending outwardly towards the loading stage from the transmission module for pressing one of keys of the keyboard, and the at least one first key pressing module comprising a servo motor located on the transmission module, and electrically connected to the control unit;
• a rod coaxially coupled to a rotary shaft of the servo motor;
• and a cam coaxially connected to the rod for pressing the one of the keys of the keyboard by the servo motor, and the cam comprising a main body coaxially coupled to the rod;
• and a protrusive portion formed on a circumferential surface of the main body, wherein, when the servo motor rotates the cam by one of different rotation angles, the cam is rotated to press the one of the keys through one of the main body and the protrusive portion so that the one of the keys is pressed down by one of two different declining distances;
• at least one second key pressing module disposed on the base, and extending outwardly towards the loading stage from the base for pressing another of the keys of the keyboard;
• and
• a control unit electrically connected to the servo motor of the at least one first key pressing module, the at least one second key pressing module and the transmission module,
• wherein comparing to the at least one second key pressing module, the at least one first key pressing module is more prominently extended above the loading stage.
