Thus, there is an advantage that the transfer film (F) can be continuously supplied into the water tank (510).

In addition, in the water pressure transfer automation system, the transfer film supply unit 500 divides the transfer film F on the water surface S by a predetermined length L, and the water surface S of the aqueous solution S And a compartment separation unit 530 running at the same movement speed and direction A as the movement speed and direction of the chain belt 520. While floating on the water surface S partitioned by 530, the chain belt 520 and the partition separation unit 530 may travel at the same speed in the direction A in which the aqueous solution flows. Accordingly, even when the transfer film F is continuously supplied into the water tank 510 and advanced in the travel direction A, the transfer film 400 moves on the transfer film F by the transfer robot 400. There is an advantage that the pressure can be made by pressing (P).

In addition, the hydrostatic transfer automation system, the compartment separation unit 530 is advanced by a predetermined distance (W) in the running direction (A) of the transfer film (F) in the state of partitioning the water surface (S). Afterwards, the reciprocating movement in the water tank 510 is possible so as to be reversed by a predetermined distance W in a direction opposite to the traveling direction A of the transfer film F in a state spaced apart from the water surface S. Therefore, there is an advantage that can be repeatedly partitioned a predetermined region of the transfer film (F) continuously supplied from the rear of the water tank (510).

In addition, the hydraulic transfer transcription system, the compartment separation unit 530 is disposed in a state extending in a direction crossing the traveling direction (A) of the transfer film (F), the contact with the water surface (S) Thus, the partition member 531 which partitions the water surface S, and the partition member 531 at the rear of the partition member 531 in a state spaced apart from the partition member 531 by a predetermined interval L. Since the active liquid blocking member 532 is disposed side by side and blocks the active liquid Q to be prevented from propagating to the rear region of the transfer film F floating on the partitioned water surface S, the partition is separated. The active liquid Q can be sprayed only on the water surface S partitioned by the unit 530.

In addition, the hydraulic pressure transfer automation system is a flat member which is arranged so that the active liquid blocking member 532 of the compartment separation unit 530 does not contact the water surface S, and is erected against the water surface S. When the compartment separation unit 530 runs forward, the active liquid Q remaining in the active liquid blocking member 532 mostly flows down to be removed. Accordingly, as shown in FIG. 13, the partition separation unit 530 is opposite to the traveling direction A of the transfer film F in the state where the partition member 531 is raised (530c in FIG. 13). In the case of reversing by a predetermined distance (W) (530d in FIG. 13), the new transfer film supplied from the rear of the water tank 510 is dropped by the active liquid Q remaining in the active liquid blocking member 532. F) It has the advantage that there is no fear of contamination.

And, the water pressure transfer automation system, the transfer film supply unit 500, the water tank 510 so as to spray the active liquid (Q) on the surface (S) partitioned by the partition separation unit 530. Since the active liquid nozzle 550 is reciprocated in the traveling direction A of the transfer film F and the opposite direction therein, the active liquid (S) is partitioned on the water surface S partitioned by the partition separation unit 530. Q) can be sprayed quickly and uniformly.

In addition, the hydrostatic transfer automation system, the articulated robot 400 is configured to hold the jig 10 to move up and down and left and right and tilt, the transfer robot 400 is shown in FIG. As described above, in the state where the holding portion 14 of the jig 10 is gripped so that the falling surface of the transfer object P is inclined by the water surface S by a predetermined inclination angle α, the transfer object P Since any one of the lower surfaces of the first contacting the upper surface of the transfer film (F), and then the other side of the lower surface of the transfer object (P) can be gradually lowered until it contacts the water surface (S), Compared to the case where the object P is held horizontally to contact the entire surface of the descending surface of the transfer object P at the same time, the generation of bubbles in the aqueous solution is reduced and the printing of the desired pattern can be accurately performed. .

In addition, the hydrostatic transfer automation system, the transfer robot 400, the fixed bar 410 coupled to the final joint of the articulated joint, and the jig is rotatably coupled to both ends of the fixed bar 410, respectively, the jig Since the first gripping lever 420 and the second gripping lever 430 are provided to grip 10, the gripping portion 14 of the jig 10 can be quickly grasped or released.

In addition, the hydrostatic transfer automation system, when the second rotating unit 620 of the second reversing unit 600 is in the first position, the transfer object (P) is mounted for a predetermined time to be inclined with respect to the horizontal plane. Therefore, the aqueous solution and the transfer film (F) buried on the surface of the transfer object (P) can be quickly flowed down along the inclined surface of the transfer object (P) can be removed.

In the following, an example of a method of hydraulically transferring using the hydraulic transfer automation system having the above-described configuration will be described.

First, as shown in FIG. 3, the worker mounts and transfers the transfer object P to the mounting part 15 of the jig 10. (Subject installation step, S100)

The jig 10 on which the transfer object P is mounted is placed on a conveyor belt (not shown) of the initial cleaning unit 100 so that the mounting portion 15 of the jig 10 faces upwards. When the initial cleaning unit 100 is operated, the jig 10 is moved at a predetermined speed by the conveyor belt (not shown), and the dust or other foreign matter is washed from the transfer object P, and thereafter, high pressure air Foreign matter and static electricity remaining on the surface is additionally removed by the antistatic unit 200 for spraying. (Initial Cleaning Step, S200)

Thus, the transfer object P from which foreign substances and static electricity are removed by the antistatic unit 200 is transferred to the first reversing unit 300, and the jig 10 on which the transfer object P is mounted is made of the first transfer unit P. 1 In the state held by the first jig gripping portion 330 of the inversion unit 300, the jig 10 from the first position (shown in FIG. 4) where the mounting portion 15 of the jig 10 is directed upward. ) Is rotated by 180 degrees to the second position (shown in FIG. 7) facing downward. After the change of direction is completed, the first jig gripping portion 330 is moved to a release position (shown in FIG. 5) for releasing the jig 10. (First reversal step, S300)

On the other hand, after changing the jig 10 in the 180-degree direction, the transfer film supply unit 500 continuously supplies the pattern-printed transfer film F while floating on the aqueous solution of the water tank 510. The transfer film F thus supplied is the same speed as the moving speed and direction of the chain belt 520 by the flow of the aqueous solution and the rotation of the chain belt 520, as shown in FIG. 10. And it continues to travel forward on the water surface (S) phase of the aqueous solution in the direction (A), it runs without stopping during the operation of the hydraulic system. At this time, the partition separating unit 530 also partitions the water surface S by a predetermined length L by the partition member 531 contacting the water surface S (530a in FIG. 12). At the same movement speed and direction A as the moving speed and direction A of the chain belt 520, driving starts on the water surface S of the aqueous solution. (Transfer film supply stage, S400)

As shown in FIG. 12, while the compartment separation unit 530 starts to move forward by a predetermined distance W, the active liquid nozzle 550 is a water surface partitioned by the compartment separation unit 530. The water surface S partitioned by the partition separation unit 530 while reciprocating 2 to 3 times by a predetermined distance L in the traveling direction A and the opposite direction of the transfer film F on the S By spraying the active liquid (Q) evenly on the upper surface of the transfer film (F) floating on the), to make the transfer film (F) in the transferable active state. At this time, the active liquid Q sprayed by the active liquid blocking member 532 and the barrier film 540 is transferred to the transfer film so that the active liquid Q is sprayed only on the foremost region of the transfer film F floating on the aqueous solution. (F) is blocked so as not to propagate to the rear region. (Active liquid spraying step, S500)

After the transfer film F on the water surface S is activated in this way, the transfer robot 400 includes the first grip lever 420 and the second grip lever 430 as shown in FIG. 9. The tank 510 of the transfer film supply unit 500 includes the transfer object P while the grip portion 14 of the jig 10 is turned by the first inversion unit 300. 14, and after holding the jig 10 so that the falling surface of the transfer object P is inclined by the predetermined angle of inclination α with the water surface S, the transfer object P The lower end of the lower surface of the) is first contacted by pressing the upper surface of the transfer film (F), and then gradually lowered the transfer object (P), as shown in Figure 15 the lower end of the lower surface of the transfer object (P) By pressurizing and contacting the negative water surface, the whole of the falling surface of the said to-be-transferred object P is hydraulic-transferred. This transfer process, as shown in Figure 12, the transfer film (F) on the water surface (S), the chain in the state floating on the water surface (S) partitioned by the partition separation unit 530, Together with the belt 520 and the compartment separation unit 530, the driving is performed for a predetermined distance W in the direction A in which the aqueous solution flows. Thus, when the transfer process of the transfer object (P) is completed, the transfer robot 400 takes out the jig 10 from the water tank 510, the compartment separation unit 530, as shown in FIG. Likewise, after the partition member 531 is raised to be spaced apart from the water surface S (530c in FIG. 13), the predetermined distance in the opposite direction to the traveling direction A of the transfer film F in this raised state ( Backward (W) (530d in FIG. 13), and the partition member 531 is lowered again (530a in FIG. 13) to contact the water surface (S) to return to the initial position. (Transfer phase, S600)

Subsequently, the transfer robot 400 moves the jig 10 to the second inversion unit 600 in which the second rotation part 620 is in the first position, as shown in FIG. 17. The second jig gripping portion 630 moves to a gripping position (shown by a solid line in FIG. 16) for gripping the jig 10 to grip the jig 10. Thereafter, the second rotating part 620 maintains the posture for a predetermined time at the first position, whereby the transfer object P is mounted for a predetermined time in a state inclined 30 degrees with respect to the horizontal plane. As described above, while the transfer object P is placed in an inclined state, the aqueous solution and the transfer film F that are buried on the surface of the transfer object P quickly follow the inclined surface of the transfer object P. It is removed by flowing down. (Residue removal step, S700)

After the aqueous solution and the transfer film F, which are buried on the surface of the transfer object P, are first removed, the second rotating part 620 may have the mounting part 15 of the jig 10 facing downward. From the first position (shown in FIG. 17) in which the object to be transferred P is inclined 30 degrees with respect to the horizontal plane, from the mounting portion 15 of the jig 10 to the second position (shown in FIG. 18) upwards. By rotating, the jig 10 is turned so that the mounting portion 15 on which the transfer object P is mounted is directed upward. (Second inversion step, S800)

In this way, the jig 10 redirected by the second inversion unit 600 is transferred to the late cleaning unit 700 by the transfer device 650, and the late cleaning unit 700 is transferred to the piezoelectric body. By spraying the washing water onto the object P, the aqueous solution and the transfer film F remaining in the transfer object P on which the pattern is printed are washed and removed. (Later cleaning step, S900)

The transfer object P washed by the late cleaning unit 700 continues to move and is transferred to the drying unit 800, and the drying unit 800 applies hot air to the surface of the transfer object P. By drying the washing water, the water pressure transfer step of the transfer object P is completed. (Drying stage, S950)

In the above-described hydraulic transfer method, the first reversal step (S300) for redirecting the jig 10 so that the mounting portion 15 of the jig 10 to which the transfer object P is mounted is directed downward, and the transfer is performed. The robot 400 grips the jig 10 and presses one surface of the transfer object P on the upper surface of the transfer film F to transfer the transfer film F, and the transfer object. Since the mounting part 15 of the jig 10 to which the (P) is mounted is provided with a second inversion step S800 for turning the jig 10 to face upward, a series of processes are simultaneously performed. It can be easy to automate the process, and through this automation there is an advantage that it is possible to perform a uniform and rapid hydraulic transfer printing on a large number of the transfer (P).

In addition, the hydraulic transfer method, after the transfer step (S600), by mounting the jig 10 to the second inversion unit 600 inclined for a predetermined time, the aqueous solution remaining in the transfer object (P) and Since the residue removal step (S700) for removing the transfer film (F) is provided, the aqueous solution and the transfer film (F) buried on the surface of the transfer object (P) is inclined surface of the transfer object (P) Therefore, there is an advantage that can be removed quickly flowing down.

In addition, the hydraulic transfer method, in the transfer step (S600), the transfer film (F) floating on the aqueous solution in the water tank 510 together with the compartment separation unit 530 predetermined speed and direction (A). Since the transfer film (F) continues to move forward, the transfer film (F) to run by the transfer robot 400, while the transfer film (F) is continuously supplied into the water tank (510) to advance in the travel direction (A). There is an advantage that the water pressure transfer can be continued by pressing the transfer object (P) on the phase.

In the hydraulic transfer method, the active liquid Q injected by the active liquid blocking member 532 and the blocking membrane 540 does not propagate to the rear region of the transfer film F in the active liquid injection step S500. Since it is blocked, the active liquid (Q) can be sprayed only to the foremost region of the transfer film (F) floating on the aqueous solution, the transfer film (F) supplied from the rear of the water tank 510 by the active liquid (Q) By maintaining a constant tension without melting, there is an advantage that the transfer film (F) can be continuously supplied to the front of the water tank 510 at a predetermined speed.

In the present embodiment, the length of the connection member 533 that connects the partition member 531 and the active liquid blocking member 532 to each other is not fixed but fixed, but the length of the connection member 533 is variable. By configuring to be adjustable, the distance between the partition member 531 and the active liquid blocking member 532 may be configured to be variably adjustable. When the distance between the partition member 531 and the active liquid blocking member 532 is adjusted, the area of the transfer film F partitioned by the partition separation unit 530 can be adjusted, thereby providing a pith having various lengths. The object P can be easily transferred by hydraulic pressure.

The technical scope of the present invention is not limited to the contents described in the above embodiments, and the equivalent structure modified or changed by those skilled in the art can be applied to the technical It is clear that the present invention does not depart from the scope of thought.
