- the present invention relates to laminated parts on which two-dimensional codes are printed.
- a two-dimensional code can be easily printed by printing it on a substantially flat surface with an appropriate width on the part.
- a two-dimensional code printed on a substantially flat surface can be easily read because the light and dark portions reflect light substantially uniformly.
- FIG. 6 is a perspective view illustrating a stator (laminated part) included in the electric motor.
- the laminated component 1 is configured by laminating a plurality of metal thin plates 2 each formed in an annular shape. Each thin plate 2 is provided with a plurality of protrusions 3 projecting inwardly of the ring. The thin plates 2 are laminated at positions where the convex portions 3 overlap each other.
- the laminated component 1 When the laminated component 1 is incorporated into an electric motor, coils are attached to the overlapping protrusions 3, and then flanges are attached to the upper surface 11 and the lower surface 12 of the core block. Thus, the upper surface 11 and the lower surface 12 of the core block are not exposed to the outside in use.
- the two-dimensional code when a two-dimensional code is printed on the laminated surface, the two-dimensional code may not be printed cleanly due to the streaks between the laminated thin plates. Also, when reading the printed two-dimensional code, there is a problem that the reading becomes difficult due to the reflection of light on the streaks.
- the above problem is solved by tilting the printing direction of the two-dimensional code from the streaks on the laminated surface.
- One aspect of the present disclosure is a laminated component configured by laminating thin plates, wherein the side portions of the thin plates are inclined at a predetermined angle with respect to the lamination direction of the thin plates on the lamination surface formed by laminating the thin plates. It is a laminated part on which a two-dimensional code is printed.
- One aspect of the present disclosure facilitates printing of two-dimensional codes and reduces reading errors.

- FIG. FIG. 3 is a perspective view illustrating a laminated component according to another embodiment of the invention
- 1 is a schematic diagram illustrating a two-dimensional code
- FIG. 4 is a diagram showing an example of a two-dimensional code printed at an angle with respect to the streaks on the layered surface
- FIG. 10 is a diagram illustrating the positional relationship between dark cells and streaks when a two-dimensional code is printed at an angle to the streaks
- It is a perspective view which illustrates the stator with which an electric motor is provided.
- FIG. 1 is a perspective view illustrating a laminated component according to one embodiment of the invention.
- FIG. 1 shows a circular stator included in an electric motor as an example of a laminated component 1.
- FIG. 2 also shows a polygonal (rectangular) stator included in an electric motor as an example of the laminated part 1 .
- the laminated part 1 in addition to the core block used for the stator and rotor of the electric motor, any part may be used, such as a core block of a transformer, as long as it is formed by laminating thin plate-like members. can be anything.
- the laminated component 1 is configured by laminating a plurality of metal thin plates 2 each formed in an annular shape.
- a two-dimensional code 4 is printed on a laminated surface 13 formed by laminating a plurality of thin plates 2 .
- a characteristic configuration of the laminated component 1 according to this embodiment is that the two-dimensional code 4 is printed at a predetermined angle with respect to the lines 15 formed between the thin plates 2 on the laminated surface 13 . be.
- the two-dimensional code 4 is printed on the lamination surface 13 of the laminated part 1 at a predetermined angle with respect to the lamination direction of the thin plates 2 .
- the two-dimensional code 4 may be printed by directly transferring or spraying dark ink onto the lamination surface 13 by, for example, a thermal transfer method or an inkjet method. Alternatively, the two-dimensional code 4 may be printed by stamping the two-dimensional code 4 directly on the lamination surface 13 using a laser stamping machine. As the two-dimensional code 4, a general matrix-type two-dimensional code such as QR code (registered trademark), DataMatrix, or MaxiCode can be used.

- MaxiCode MaxiCode
- FIG. 3 is a schematic diagram illustrating a two-dimensional code.
- a two-dimensional code is generally configured as a rectangular shape in which a plurality of cells are arranged in a grid. Each cell is square in its outline and reflects light with a predetermined reflectance on its surface.
- dark cells 5 with low light reflectance and bright cells 6 with high light reflectance are arranged in a grid.
- the two-dimensional code 4 also includes a predetermined characteristic pattern 7 (finder pattern) used for detecting the code position and cell size.
- FIG. 4 is a diagram showing an example of a two-dimensional code printed at an angle with respect to the streaks on the laminated surface.
- FIG. 5 is a diagram illustrating the positional relationship between the dark cells 5 and the streaks when the two-dimensional code is printed at an angle to the streaks. 4 and 5, one side of the rectangular shape of the two-dimensional code 4 is printed at angles of 0, 10, 15, 25 and 45 degrees with respect to the streaks 15 of the lamination surface 13. shows an example.
- FIGS. 4 and 5 when the two-dimensional code 4 is printed without setting an angle (at 0 degrees) with respect to the lines 15, there are many portions where all sides of the dark cells 5 overlap the lines 15. occur.
- the streaks 15 are portions between the laminated thin plates 2 and are streak-like recessed or swollen with respect to the laminated surface 13 . Therefore, it looks like a dark black line compared to the side of the thin plate 2 . If the side of the dark cell 5 overlaps this portion, it becomes difficult to identify the contour position of the dark cell 5, and errors are likely to occur when reading the two-dimensional code 4.
- FIG. when the two-dimensional code 4 is printed, there are some areas where the sides of the dark cells 5 cannot be printed well.
- the sides of the dark cells 5 only partially overlap the lines 15. FIG. Therefore, errors during reading of the two-dimensional code 4 are reduced, and problems during printing are less likely to occur.
- the angle of the two-dimensional code 4 with respect to the lines 15 should be such that the contours of the cells forming the two-dimensional code 4 become clear. This angle changes depending on the length of the sides of the cells forming the two-dimensional code 4 and the width of the lines 15 formed on the layered surface 13 . For example, if the length of the side of the cell is A [mm], the thickness of the line 15 is T [mm], and the angle of inclination is ⁇ [degrees], the two-dimensional code It has been found from experiments and the like that the reading error of 4 is sufficiently low.
- the inclination of the two-dimensional code 4 with respect to the lines 15 may be relatively small (for example, 5 degrees ⁇ 10 degrees).
- the inclination of the two-dimensional code 4 with respect to the lines 15 must be increased to some extent (for example, 15 degrees or more).
- the thickness of the lines 15 varies depending on the size of the gap between the thin plates 2, the size of the fracture surface when the thin plate 2 is punched (because the fracture surface looks black due to light reflection), and the like. Therefore, the printing angle of the two-dimensional code 4 may be appropriately changed according to the streaks generated on the lamination surface 13 of the laminated component 1 .
- a vision sensor is attached to a laser marking machine, a robot, or the like to image the lamination surface 13 of laminated parts. Then, a known image analysis is performed on the captured image of the laminated surface 13 to detect the streaks 15 formed on the laminated surface 13 . Then, the thickness T of the detected streaks 15 is calculated, and the angle at which the two-dimensional code 4 is tilted based on the calculated thickness T of the streaks 15 and the cell side length A of the two-dimensional code 4 to be printed. Calculate ⁇ . Then, the two-dimensional code 4 can be printed by inclining the angle of the laminated component with respect to the laser marking machine based on the calculated ⁇ .
- the laminated component 1 when the two-dimensional code 4 is printed on the laminated surface 13, it is possible to print so that the outline of each cell becomes clear. Further, reading errors when reading the two-dimensional code 4 printed on the lamination surface 13 are reduced.
