The present invention relates to a printing apparatus for a mobile phone front cover, and more particularly, having a track-shaped conveying portion, which improves productivity according to a shortening of printing time, and removes static electricity generated on the surface of the front cover and a printed pattern. It is to obtain a good printing state by providing a drying function.

1 is a perspective view of a mobile phone front cover described above.

Referring to FIG. 1, the mobile phone front cover 1 includes a plurality of through holes for exposing the key pad and the display unit to the outside of each of the built-in components, and checks the display contents in the through holes for exposing the display unit. The transparent window 2 of the transparent body is attached.

Such a front cover 1 requires a printing mechanism to print a specific design or logo.

The above printing mechanism is mainly a transfer printing mechanism (pad printing mechanism) for transferring the original drawing and printing on the front cover 1, or a direct printing mechanism (screen printing mechanism) for injecting ink into a screen plate formed by penetrating a specific shape. Is applied.

Looking at the conventional configuration of these, it is composed of a printing drive unit for performing printing, a mounting table for the built-in printing drive unit, a jig in which the front cover 1 is fixed in position in the vertical downward of the printing drive unit.

Here, when the pad printing mechanism is provided as the printing driver, an ink supply mechanism for supplying ink to a transfer pad, a printing plate for transferring a pattern or a logo onto the transfer pad, and a driving mechanism for moving the transfer pad and the ink supply mechanism. It consists of.

In addition, the screen printing mechanism includes a screen plate formed by penetrating a pattern or logo to be printed, an ink supply mechanism for supplying ink through the screen plate, and a driving mechanism for driving them.

Each printing work mechanism configured as described above mounts the front cover 1 to the jig and drives the driving mechanism so that the desired printing work can be performed.

In the above-described conventional printing tool, the operator attaches the front cover to a single jig and after the printing operation is completed, the delay of the working time occurs because the front cover has to be replaced one by one by the operator's manual operation.

In addition, the printing part is dried by the printing finishing process after the printing operation, such a drying operation is to separately collect the front cover with the logo, the pattern is printed, and put it into a drying work mechanism provided independently to complete the printing operation Done.

Such a separate drying process causes disadvantages of economic and time work due to the accompanying independent drying tools, and in particular, the front cover made of synthetic resin material is printed in a state in which static electricity remains on its surface. Since the work is performed, the ink spreading or printing position is uneven due to static electricity, which makes it difficult to expect an excellent printing state.

The present invention has been devised to solve the above-described problems, so that a large number of front cover printing operations can be performed quickly, and the front cover of a mobile phone provided with a function of removing static electricity before printing and drying after printing. It is an object of the present invention to provide a printing apparatus.

As described above, a plurality of front covers are orbitally conveyed by the transfer mechanism unit, and printing is performed by the print work unit, thereby enabling rapid work on a large number of front covers.

The transfer mechanism portion is provided on a work table before the front cover printed in the printing operation portion is discharged from the discharge portion is provided with a drying mechanism for drying the printing surface of the front cover.

The process of drying the printed side by this configuration is carried out in one apparatus to realize the simplification of the manufacturing process.

The transfer mechanism is characterized in that the front cover supplied by the jig from the supply unit is provided on the work table before proceeding to the printing work unit is provided with an electrostatic removal mechanism for inducing and removing the static electricity remaining on the outer surface of the front cover .

This configuration allows the front cover to remove static electricity from the surface to be printed before printing is performed so that the surface adhesion of the ink is more stable.
