Abstract
A braille printing device includes a device body; a linear actuator with an actuator body and an actuator hammer; a liquid ejection unit, including a liquid container a piston assembly including a piston member with a conical bottom end and an o-ring that resides in a ring indentation with a tapered indentation, a lubrication canal system, a connection tube, and a tapering tube; and a control unit, such that the braille printing device ejects projectiles of ejected resin droplets, which are deposited as spherical domes of printing resin on a printing substrate to form a braille text.
Claims27
A braille printing device, comprising:
- (a) a device body, which is configured to be detachably connected to a moveable portion of an engraving machine, such that the device body is configured to be longitudinally and laterally moveable by a corresponding movement of the moveable portion of the engraving machine;
- (b) a linear actuator, which comprises:
- an actuator body, which is connected to the device body;
- and
- an actuator hammer, which is configured to be vertically slidable, relative to the actuator body;
- and
- (c) a liquid ejection unit, comprising:
- a liquid container, which comprises a container interior with an upper opening, such that the container interior is configured to contain a liquid resin;
- a piston assembly, which penetrates into the container interior via the upper opening, such that a lower part of the piston assembly seals walls of the container interior, and such that downward pressure on an upper part of the piston assembly pressurizes the liquid resin in the container interior;
- and
- an ejection aperture, which is in fluid contact with the liquid container;
- such that when the actuator hammer strikes the upper part of the piston assembly, this causes the lower part of the piston assembly to impact with the liquid resin, such that the lower part of the piston assembly causes a shockwave to travel through the liquid resin, such that the shockwave pushes out an ejected resin droplet from the ejection aperture, such that the ejected resin droplet is ejected downwards from the ejection aperture;
- such that the ejected resin droplet impacts with a surface of a printing substrate below the ejection aperture, such that the ejected resin droplet forms a braille dot on the surface of the printing substrate.
