Abstract
A device for dispensing a viscid material includes a supporting body constructed by a carriage. A ball screw is installed within the supporting body. A rod piston is mounted on one end of the ball screw. A transmission module is mounted on a nut of the ball screw. The transmission module is engaged with an actuator controlled by a control circuit device. The control circuit device, which includes a switch and a circuit board, etc, controls the positive and negative rotations and the stop operation of the actuator. A trigger is set up on one side of the supporting body. When the trigger is pressed, the actuator is driven to rotate in the positive direction to drive the ball screw to move forwardly in a stable way. While the trigger is released, a sensor is activated to drive the actuator to rotate in the negative direction.
