Abstract

A stamping device includes a stamping data generator configured to create stamping data to form a stamp image on a surface of a processing target, a positioning data generator configured to create positioning data to position the processing target, and a controller configured or programmed to control an operation of the processing tool. The controller includes a first controller configured or programmed to control the processing tool such that stamping is performed, based on the positioning data at a first stamping energy, on the processing target including a protective sheet attached thereto in a predetermined area including a stamping area where the stamp image is to be formed, and a second controller configured or programmed to control the processing tool such that stamping is performed, based on the stamping data at a second stamping energy equal to or different from the first stamping energy, on the processing tool in a state of having the protective sheet peeled off therefrom.

First claim

What is claimed is:

1. A stamping device that performs stamping on a surface of a processing target, the stamping device comprising:
a processing tool movable at least upward and downward;
a protective sheet that is able to be attached to and peeled off from the surface of the processing target;
a table supporting the processing target;
a stamping data generator that generates stamping data to form a stamp image on the surface of the processing target, based on image data corresponding to the stamp image;
a positioning data generator that generates positioning data based on the stamping data, the positioning data indicating a first stamping position of the processing tool; and
a controller that controls an operation of the processing tool; wherein
the controller includes:
a first controller that controls the processing tool to perform a first stamping located at the first stamping position and at a first stamping energy; and
a second controller that controls the processing tool to perform a second stamping based on the stamping data at a second stamping energy which is greater than the first stamping energy;

the first stamping stamps the protective sheet attached to the surface of the processing target, and does not stamp the surface of the processing target; and
after the protective sheet is peeled off from the surface of the processing target, the second stamping stamps the stamp image on the surface of the processing target.

2. A stamping device according to claim 1 , wherein the positioning data represents a plurality of stamping indentations for positioning on an outermost line of the stamping area.

3. A stamping device according to claim 1 , wherein
the stamping area is square or rectangular, and the image data represents a two-dimensional symbol that is to be formed in the stamping area;
the stamping data generator generates the stamping data based on the image data representing the two-dimensional symbol; and
the positioning data generator generates positioning data representing a plurality of stamping indentations for positioning on a horizontal line in the stamping area and a plurality of stamping indentations for positioning on a vertical line that is vertical to the horizontal line and is in the stamping area.

4. A stamping device according to claim 3 , wherein the positioning data generator generates positioning data representing a plurality of stamping indentations for positioning on each of outermost horizontal lines in the stamping area and a plurality of stamping indentations for positioning on each of outermost vertical lines in the stamping area.

5. A stamping device according to claim 4 , wherein the positioning data generator generates positioning data representing a stamping indentation for positioning at each of four corners of the stamping area, at least one stamping indentation for positioning on the horizontal line extending from each of the corners and at least one stamping indentation for positioning on the vertical line extending from each of the corners, the at least one stamping indentation for positioning on the horizontal line and the at least one stamping indentation for positioning on the vertical line being of the same number.

6. A stamping device according to claim 5 , wherein a total number of the stamping indentation for positioning at each of the corners, the at least one stamping indentation for positioning on the horizontal line extending from the each corner and the at least one stamping indentation for positioning on the vertical line extending from the each corner is seven.

7. A stamping device according to claim 1 , wherein the protective sheet is softer than the processing target.

8. A stamping device according to claim 1 , wherein the protective sheet is made of a synthetic resin transparent adhesive tape.

9. A stamping device according to claim 1 , wherein the processing target is a steel medical tool.
