摘要：
Disclosed is an automatic metal printer which prints a camera-photographed and computer-processed image on a surface of a hard material, such as a metal sheet, through a dot matrix printing type method wherein brightness of the printed image is expressed in accordance with density of dots in the dot matrix formed on the surface of the hard material. The automatic metal printer includes a platform which reciprocates forward and rearward in a lower portion of a body by a motor-operated first ball screw. A saddle is installed at a position above the platform so as to reciprocate to the left and right in the body by a motor-operated second ball screw. A dotter is vertically installed on the saddle so as to dot the upper surface of the hard material seated on the platform to print a desired image.
技术问题语段：
However, the cutting process of printing an image on a metal surface using the cutting tool is problematic in that it consumes excessive time and generates dust and chips while printing.|However, the conventional three-dimensional metal printer uses a cutting process to print an image on a metal surface, so the metal printer generates dust and chips during the rough-cutting process and the fine-cutting process, and fails to produce a precise image on the metal surface.|In addition, the three-dimensional metal printer must be provided with a belt transmission mechanism comprising belts and pulleys to transmit rotating force to the spindles, thereby undesirably having a complex construction.|Another problem of the conventional metal printers including the three-dimensional metal printer resides in that it is necessary for a user to manually load and unload metal materials on and from a printing position of a printer, thus increasing time consumption and sometimes causing safety hazards while printing.
技术功效语段：
Another object of the present invention is to provide an automatic metal printer which has a means for automatically loading and unloading hard materials on and from a printing position, thus being completely automated.
权利要求：
What is claimed is:
1. An automatic metal printer, comprising:
a platform reciprocating forward and rearward in a lower portion of a body by a motor-operated first ball screw, with a seat depression formed at a middle portion of an upper surface of said platform to seat thereon a hard material to be printed with an image by the printer;
a saddle installed at a position above the platform so as to reciprocate to the left and right in said body by a motor-operated second ball screw; and
a dotter vertically installed on said saddle so as to dot an upper surface of the hard material seated on the platform to print the image on the surface of the hard material, said dotter comprising:
a diamond tip vertically installed at a lower portion of a front surface of said saddle while being biased by a spring so as to reciprocate upward and downward;
a solenoid actuator vertically installed at the front surface of said saddle such that a plunger of the solenoid actuator comes into contact with an upper surface of said diamond tip and repeatedly pushes the upper surface of the diamond tip downward; and
an automatic loading unit, said automatic loading unit comprising:
two vertical cartridges standing upright at a rear portion of said body, and each sequentially receiving a plurality of metal materials therein; and
a feeder installed at the rear portion of the body to surround lower ends of the two vertical cartridges, said feeder reciprocating to the left and right in the body by a motor-operated third ball screw so that the feeder alternately pushes metal materials stacked in the two cartridges to sequentially load the metal materials into the seat depression of the platform.
2. The automatic metal printer according to claim 1, further comprising an automatic unloading unit mounted to a central portion of a front of said body such that the automatic unloading unit automatically unloads each metal material from the platform when the platform is moved forward to a predetermined position.
3. The automatic metal printer according to claim 1, wherein a shock absorbing material is attached to the upper surface of said diamond tip.
4. The automatic metal printer according to claim 1, wherein a height adjusting screw is installed on said saddle at an upper portion above the solenoid actuator so as to adjust a height of said plunger.
