A bottle grabbing mechanical arm, comprising a base (1), a left clamping claw (2), a right clamping claw (3), a stepper motor (4), a left clamping claw connecting member (5), a right clamping claw connecting member (6), a sliding rail (7), a sliding block (8), a closing positioning piece (9), an opening positioning piece (10), an opening detecting switch (11) and a closing detecting switch (12). The left clamping claw (2) and the right clamping claw (3) are symmetrical to each other, and the opposite inner sides thereof are both provided with a convex groove, the two convex grooves fitting together and corresponding to the shape of a bottle body. The left clamping claw (2) moving towards the right is the 'closing' process of the mechanical arm, and the positioning accuracy of grabbing a bottle during the 'closing' process of the mechanical arm is executed by means of the closing positioning piece (9) triggering the operation of the closing detecting switch (12); the left clamping claw (2) moving towards the left is the 'opening' process of the mechanical arm, and the positioning accuracy of releasing a bottle during the 'opening' process of the mechanical arm is executed by means of the opening positioning piece (10) triggering the operation of the opening detecting switch (11). The opening and closing of the clamping claws (2, 3) is driven by means of a leadscrew and nut pair of the stepper motor (4), and positioning accuracy thereof is controlled by means of the positioning pieces (9, 10) triggering the detecting switches (11, 12); the structure is simple, control is accurate, and safety performance is high. |
