Description

Pad printing device

The present invention relates to a pad printing apparatus, and more particularly, to a pad printing apparatus for printing on a substrate having a curved surface.

As is well known, the window glass substrate forming the front surface of the portable terminal has a trend that one or both edges are rounded with a certain curvature in order to enhance the aesthetics of the appearance and to enhance the side effect.

Conventionally, an edge cover film is attached to the edge of the window glass substrate so that the edge portion of the display panel of the mobile terminal is exposed to the outside so as not to damage the front appearance of the mobile terminal.

However, instead of the edge cover film that is recently attached to the magnetic field of the window glass substrate, it is easy to apply the design according to the various sizes, reduce the work process and reduce the manufacturing cost. Printing method is applied.

In particular, a pad printing method is mainly used to perform the above edge cover printing on the edge of a curved window glass substrate having rounded edges.

Pad printing is one of the printing techniques for transferring a two-dimensional plane image into a three-dimensional object. The pad printing method is used to transfer an image from a printing plate using a soft pad such as silicon, and then again. By transferring to a three-dimensional print object, there is an advantage in that the printing process is simple and the image can be easily printed on a curved three-dimensional solid surface.

Korean Unexamined Patent Publication No. 10-2003-0051579 discloses a "printing apparatus for a mobile phone front cover" to which the pad printing method described above is applied.

 The printing pad 60 pressurized on the tape support 193 elastically deforms on the ink removing adhesive tape, and the lower surface used for transferring the ink comes into contact with the adhesive surface of the ink removing adhesive tape 185, thereby eventually printing the substrate 10. The remaining ink is separated and removed by the adhesive force of the ink removing adhesive tape 195.

Then, when the remaining ink remaining in the printing pad 60 is removed through the ink removing adhesive tape 195 and the printing pad 60 is lifted and separated, the ink removing adhesive tape 195 through the tape feeder 192. The used portion of the tape to the tape collection winding roll (196).

Thus, a new portion of the ink removal adhesive tape 195 released from the tape supply take-up roll 192 is laid on the tape support 193 to make the remaining ink removable state of the next printing pad.

As described above, the pad printing apparatus 100 according to the present exemplary embodiment transfers the curved edges of the substrate 10 through the printing pad 60 to the substrate transfer, substrate alignment, pad transfer, ink coating, ink transfer, ink transfer, and ink drying required for the edge cover printing process. In addition, the substrate printing and residual ink removal processes are automatically performed to increase productivity of the substrate printing operation, and also to enable precise printing of the substrate.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications or changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. In addition, it is natural that it belongs to the scope of the present invention.
