Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of forming a print layer by thermal transfer,

In addition, a 1: 1 size focal point between the transferred body and the ink layer is aligned by thermally transferring a print area of the transfer film to be transferred to the transfer target body in a state where the print area is larger than the transfer body and printing defects at the corners or rim And more particularly to a window heat transfer method for mobile devices and tablet PCs that can reduce costs, increase yields, and reduce costs.

A smart device such as a smart phone or a tablet PC generally includes a touch panel as an input device and prevents an electrode due to the electrode wiring from being visible in a bezel area (area other than the display) formed at a rim of the touch panel And a printing layer is formed by a design element that imparts various textures and colors.

A screen printing method, a thermal transfer method, or the like is used as a method of forming a print layer on one surface of a glass or synthetic resin film.

The screen printing method is advantageous in that the manufacturing process is simple and the printing quality is high. However, there is a problem in that steps are generated due to the thickness of the ink, thereby making it difficult to reduce the durability and slimness of the entire apparatus.

Therefore, a thermal transfer method is widely used in order to minimize steps caused by the print layer.

In the thermal transfer method, a hot stamping method is used in which a transfer method in which a transfer film coated with a transfer layer is brought into contact with a surface of a transfer object and is transferred by pressing and heating is transferred to a transfer body by heating and pressing using a hot stamping machine have.

However, in the conventional roller system, when the roller passes over a transfer body while applying a certain pressure and heat, the pressure is generally biased to the edge portion of the transfer object, And the ink used for printing is pushed when the roller passes, so that it is impossible to correct the dimension correction or the step difference of the printing region uniformly, and the yield of the work such as bubbles is lowered.

According to the conventional hot stamping method, there is a problem that the transferred printing state deviates in accordance with the flatness of the jig to be pressed and the to-be-transferred body to be engaged with the jig and thus the ink is peeled off or bubbles are generated, There is a problem that the maintenance cost is large and the yield is low.

In addition, in the conventional thermal transfer method, since the transferred body and the transferred film as transfer materials are manufactured and transferred, unprinted areas are present at edges or rim portions of the transferred body due to printing layer jamming or pressure imbalance on the surface of the transferred body, The layer is not uniformly transferred and the printing quality is deteriorated and there is a problem that a print failure that the printing pint of the ink layer on the transfer film and the outer periphery of the transferred body and the rim of the view area does not fall to 1:

If the printing failure as described above occurs, not only the transfer film but also the transferred object must be discarded, thereby lowering the yield and increasing the cost.

  In the event of a printing quality problem such as printing steps, ink jamming, bubble generation, etc. after the above-mentioned adhesion step, the printing layer is easily regenerated with a cleaning solution in which organic solvents are manufactured at an optimized ratio, To 99.9%, which is the main verification process that can reduce the production cost.

The drying step may be initial drying at a low temperature and finally drying at a high temperature in order to remove the phenomenon of change in thought of the ink generated by the high temperature during the thermal transfer, and the initial drying is performed at 70 to 80 degrees for 10 to 20 minutes , And final drying is performed at 120 to 150 degrees for 30 to 60 minutes.

The jig 20 is configured to receive and mount a transfer target body to which a transfer film is to be transferred, and is responsible for accurately aligning the positions of the transfer film and the transfer target body.

Next, the transfer body 120 is press-contacted with the transfer body 120 by press-heating the transfer body 110 having the transfer film aligned through the hot stamping module 30.

The cushioning pad may be provided on the bottom surface of the jig for accommodating the transferred object and capable of cushioning the transfer film as a transferred object by buffering the pressure of the hot stamping module. The pad may be made of a material having elasticity such as urethane, silicone, synthetic rubber, Teflon and the like. In order to fix the bottom surface of the jig and the body to be fixed and reduce the probability of bubbling during fusion, And an air hole connected to the vacuum pump is provided on the surface so that the interior of the receiving body and the seating jig can be vacuumed just before fusing.

The hot stamping module 30 may include a stamper portion having a heater which is in contact with or contacted with the body to which the transfer film is aligned by applying heat and pressure, and a lift portion for vertically moving the stamper. Here, the elevating portion may be constituted by a pressurizing cylinder operating with hydraulic pressure or pneumatic pressure.

The configuration of the hot stamping module is the same as that of the conventional hot stamping type hot stamper, and a detailed description thereof will be omitted.

Here, the transfer film is not completely bonded onto the film through the folded hot stamping module 30 or the roll stamping module 40, but the transfer film is aligned at the correct position on the film, and the transferred film is transferred This is the main process for bonding the film.

The pressing may be performed at a temperature of 100 to 250 DEG C under a pressure of 1 to 5 tons for 1 to 10 seconds.

At this time, various conditions can be set by adjusting the temperature, pressure, and time conditions under the pressing conditions of the above-mentioned warp depending on the size and thickness of the film, the physical properties of the ink, and the like.

As described above, since the transfer film is stuck on the film through the hot stamping module 30 or the roll stamping module 40, the pressure is only applied to only one side of the main plate by the roller module, It is possible to prevent the printing defects beforehand and to reproduce the printing layer easily by using the cleaning solution which has made the organic solvents at an optimized ratio in the case of the printing quality problems such as the printing step, It is possible to increase the reclamation rate of glass and other materials to 95 ~ 99.9%, which can lead to a major verification process that can reduce production costs.

FIG. 5 is a schematic view illustrating a process of attaching or bonding a transfer film to a film through a roll stamping module 40 according to a preferred embodiment of the present invention.

5, after the roll stamping module 40 is placed on the film in a state in which the transfer film 120 is stuck on the body 110 through the hot stamping module 30 as described above, You can perform this folding by stamping. Here, in the case where the transfer module is constituted by a single hot stamping module 30, the case where the present contact is performed by the hot stamping module 30 and the transfer module is constituted by a single roll stamping module 40, Is performed by the contact roll stamping module (40). That is, in the case of a single hot stamping module 30 or a single roll stamping module 40, it is possible to carry out the contact and the main contact in two consecutive processes with a time difference.

In the case where the transfer module is constituted by the hot stamping module 30 and the roll stamping module 40, contrary to the embodiment of FIG. 1, the folding is performed by the roll stamping module 40, and the present folding is performed by the hot stamping module 30 And transferred.

The buffering means 410 may be made of elastic material such as urethane or rubber.

When the transfer film 120 is aligned on the transferred body 110 and fused via the roll stamping module 40, the transfer film on the transfer body is pushed to push the ink in the print layer, Even if the static pressure roll stamping control is performed, it is difficult to press uniformly as the sequential thermal pressure is applied, and the possibility that the print layer is not uniformly transferred due to the concentration of pressure locally at the edge portion However, if the transfer film is primarily bonded to the film through the hot stamping module 30 and then folded by the roll stamping module 40 in a secondary manner, the problems occurring in the hot stamping method can be compensated The print layer of the transfer film can be transferred to the transfer body without the above-described problems.

As described above, when the transfer film is placed on the transfer target body, the transfer film is released to leave only the print layer on the transfer target body, and the formation of the print layer on the transfer target body is completed.

FIG. 6 is a flow chart schematically illustrating a thermal transfer method according to a preferred embodiment of the present invention, and FIG. 7 is a schematic view of a transferred body and a transfer film according to FIG.

A thermal transfer method according to another embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG.

First, a transfer body and a transfer film are prepared.

Here, the transferred body may be made of a synthetic resin material such as glass, PET, or PC as a base material on which a printing layer is formed. The printed layer may be made of a separate film and joined with a touch panel or a touch window. However, in the case of an integrated touch window in which a touch panel and a window are integrally formed, the integrated touch window itself may be a film.

The transfer film is a film for transferring the printing layer to the printing area of the transfer target.

The thermal transfer method according to the present invention is characterized in that the transfer film is transferred onto the transfer target body in a state in which the print area of the transfer film is formed to have an offset area larger than the print area of the transfer target body.

If the transferred body and the transfer film are made to have the same size, an unprinted area is generated at the edge or rim of the body due to a slight film size tolerance or a pressure imbalance at the time of thermal transfer, Defects are likely to occur.

Therefore, in order to eliminate the printing defects as described above, the present invention is characterized in that a transfer film is formed larger than a transfer body and a printing area on a transfer film is wider than an outer periphery of a transfer body to prevent printing defects It is possible to prevent the occurrence of the print area at the source.

The size of the offset region may vary depending on the size of the transferred body and the print region. When the offset region is formed excessively, since the transfer film and the printing ink are very small, the offset region A is formed with a size of 1 to 10 mm .

Since a special adhesive layer such as a binder for bonding a transfer object and a print layer is conventionally unnecessary by using a thermal transfer ink which is specially produced when printing the transfer film, it is possible to further reduce the additional process for adding the adhesive layer.

When the transferred body and the transfer film are prepared as described above, the transfer film formed by extending the print layer by the offset region on the transfer body is aligned.

Here, since the transfer film is formed to be larger than the transferred body by an offset region, it is necessary to accurately align the transfer film on the transfer body and the display region (unprinted region) of the transfer body and the transfer film on the film loading portion for loading the film A pinhole for alignment is formed, and the transferred body and the transfer film can be accurately aligned through the pinhole.

In order to reduce the probability that bubbles are generated when the bottom surface of the subject jig is fixed to the bottom surface of the jig and the air bubbles are generated at the time of welding, air holes connected to the vacuum pump are formed on the bottom surface of the jig, The interior is made to be in a vacuum state, and a heating and cooling function is added to the seating jig and the heated stamping portion so as to maintain a constantly optimized temperature for maintaining a constant printing quality.

When the transferred body and the transferred film are aligned, the printed layer of the transferred film is transferred to the transferred body by heat pressurization.

At this time, the hot stamping module 30 and the roll stamping module 40 described with reference to FIGS.

Also, the print layer of the transfer film can be fused and transferred to the transfer target body through the two-step bonding of the contact and the main contact by only transferring through the hot stamping module alone.

The two layers of the hot stamping module are separated from each other, and the printed layer of the transfer film can be fused and transferred to the transfer body through the two-step bonding.

In addition, it is possible to use two hot stamping modules to separate the welded joint and the main joint.

In other words, the pressing module used for the contact to the abutment is not limited to either the hot stamping or the heated roller, and the stamping part can be changed flexibly according to the characteristics of the film, ink and the body to be transferred. For example, the hot stamping module can be bonded or folded, and the roll stamping module can perform both of the function of attaching and attaching, thereby featuring a thermal transfer method that maximizes the efficiency of the work in some cases.

Here, when transferring at a time, ink jamming, bubbles, or the like may occur and print quality may be deteriorated due to unfused adhesion or printing failure may occur. Therefore, the above-described problems can be solved through two thermal fusing between the adhesion and the main surface.

The joining and joining may be performed under a pressing condition of 1 to 5 tons at a temperature of 100 to 250 DEG C for 1 to 10 seconds.

And a condition of at least one of temperature, pressure, and time may be set to be low among the set contact conditions.

In spite of the physical configuration of the compression springs, shock absorbing units, and flat support units to ensure flatness, the printed state deviations caused by the flatness are severely caused when the direct contact is performed (single thermal bonding) . Therefore, after the flatness problem is minimized by the splice, the ground contact is performed.

After completion of the thermal transfer by the contact and the completion as described above, the transfer target film and the transferred film are dried, and after the hot stamping module or the roll stamping module is subjected to the sealing process, Can be selectively added, and when there is no need for additional folding, it is feasible to start the drying process and to be able to efficiently produce the thermal transfer method.

More specifically, at the time of drying, the ink is initially dried at a relatively low temperature in order to remove a phenomenon (for example, white ink → yellowing) in which the color of ink generated by high temperature upon thermal transfer is changed, The printing quality can be improved.

The initial drying may be carried out at 70 to 80 degrees for 10 to 20 minutes, and the final drying may be carried out at 120 to 150 degrees for 30 to 60 minutes.

Further, in order to solve the problem that the adhesiveness of the print layer is poor in the case of the glass material, the plasma processing step may be further included.

When the thermal transfer is completed as described above, the transfer film is released from the transferred body to complete the formation of the print layer on the transferred body.

In the step of releasing and releasing the transfer film, a width of the print layer formed on the transfer film is made as large as an offset area, and a cutting layer is automatically formed upon pressing with the hot stamping module, the roll stamping module, etc., When the ink layer is transferred to the transfer target layer, the outer dimension fits of the glass and the ink layer are coincided with each other at a ratio of 1: 1 without a separate finishing step or operation. When the transfer film is released after transferring, It is possible to prevent printing defects such that the printing state such as the outer edge portion or the corner portion of the glass is not made smooth due to the phenomenon of partial ink fading or the like and unnecessary finishing process for smoothing the printing state of the outer frame portion, Can be removed.

 While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
