Automatic pill grasping apparatus

An automatic pill grasping apparatus, comprising:

• an enclosure comprising a base;
• a control chip;
• a pill grasping mechanism comprising a grasping arm, a nozzle, and a driving mechanism attached to the base, the grasping arm comprising a main arm, and the nozzle connected to main arm;
• and
• a pill storage mechanism comprising a plurality of pill storage cases for storing pills and an actuating mechanism attached to the base;
• wherein the control chip is configured to control the actuating mechanism to rotate the plurality of pill storage cases in a first plane substantially parallel to the base and control the to rotate the main arm about a first axis in a second plane perpendicular to the first plane, for rotating the nozzle to stretch into the one of the plurality of pill storage cases to pick a pill;
• and
• wherein the grasping arm further comprises a linkage mechanism, and a transfer mechanism;
• the linkage mechanism is pivotably mounted to the main arm, the main arm defines an opening, the transfer mechanism comprises a transfer cam which is rotatable about a second axis driven by the driving mechanism and a driving wheel mounted to the transfer cam and received in the opening of the main arm, wherein when the transfer cam rotates about the second axis, the driving wheel is rotated about the second axis by the transfer cam and is adapted to press an edge of the opening of the main arm and to drive the main arm to rotate about the first axis.
