Description

PRINTING APPARATUS

The present invention relates to a printing apparatus, and more particularly, to a printing apparatus capable of forming a pattern on a substrate.

In recent years, imprinting technology that can replace technologies based on existing lithography processes has become an issue in order to realize low cost products mainly in the display and semiconductor industries.

The imprinting technique is a pattern forming technique by press molding used for manufacturing displays such as liquid crystal display (LCD), plasma display panel (PDP), organic light emitting diode (OLED)

Various electronic devices such as an electronic circuit, a sensor, a solar cell, a flexible display, and an RFID can be easily manufactured using such a printing technique.

Further, the printing technique can simplify the process as compared with the existing lithography process, and can significantly reduce the production time and the production cost of the product. In addition, printing technology can mass produce a product with low manufacturing cost.

Unlike the conventional glass substrate, when printing technology is used, various materials such as plastic, fiber, and paper can be used as a substrate.

In the printing technique according to the related art, direct printing or indirect printing using an intaglio board or an iron plate which can realize very sharp printing is used. Depending on the superposition accuracy required for the duplicate print, the printing plate will have the form of a roll or a plate.

Depending on the characteristics of the plate-making process, the plate-type printing plate has higher precision than the roll-type printing plate. Therefore, plate-type printing plates are mainly used in processes such as semiconductors and displays that require superimposing accuracy at the exposure process level.

However, since the plate printing plate requires periodic cleaning for reasons such as drying, contamination, etc. of the ink during the printing process, it is common to provide a separate washing machine outside the printing apparatus or to install a washing machine inside the printing apparatus in order to increase the production efficiency.

However, in the conventional printing apparatus, when the conventional external or internal washing machine is used, the production efficiency is deteriorated due to the time required for cleaning and drying, and the defective cleaning leads to defective printing result. As the printing pattern becomes finer The penetration of the cleaning liquid and the cleaning agent into the inside of the printing plate pattern is reduced, and the problem of poor cleaning can be more remarkable.

Particularly, in the case of printing using the reverse offset method, the tact time for one printing is long because the cleaning must be performed after each printing, and there is a problem in which a plurality of printing plates must be operated in order to shorten the tact time .

The stage alignment unit 250 is coupled to the upper surface of the stage support frame 231 and the lower surface of the stage 210 to connect the stage support frame 231 to the stage 210.

The stage alignment unit 250 is disposed substantially in a rectangular configuration with respect to the plate surface of the stage 210 so that the stage 210 can be moved in the plate surface direction (X axis, Y axis and? Axis direction) It is the role of supporting.

 The stage alignment unit 250 includes four stage unit alignment units 260a to 260d that are disposed at four corners of the stage 210 and allow the stage 210 to move relative to the dispenser 310 do.

When the four stage unit alignment units 260a to 260d are arranged in the four corners of the stage 210 in a rectangular shape, the web pressing unit 500, which will be described later in the imprinting operation, ) Is pressed with a high pressing force, the stage 210 is not moved in any direction. That is, it is possible to prevent the stage 210 from being pushed by the web pressing portion 500.

Further, the stage 210 itself can be finely moved easily and efficiently in the X-axis, Y-axis, and? -Axis directions.

Hereinafter, for convenience of explanation, each of the four-stage unit alignment units 260a to 260d is divided into first to fourth-stage unit alignment units 260a to 260d along the counterclockwise direction with reference to the area A in FIG. 5, .

Each of the first to fourth stage alignment units 260a to 260d includes first to fourth drive motors 261a to 261d and first to fourth drive motors 261a to 261d, First through fourth ball screws 262a through 262d rotatable in forward and reverse directions by the four drive motors 261a through 261d and first through fourth ball screws 262a through 262d through the first through fourth ball screws 262a through 262d, First to fourth rotation supporting portions 267a to 267d provided on the opposite sides of the first to fourth driving motors 261a to 261d for rotatably supporting the ends of the first to fourth ball screws 262a to 262d, The first to fourth ball screws 262a to 262d and the first to fourth ball screws 262a to 262d which are movable along the longitudinal direction of the first to fourth ball screws 262a to 262d during rotation of the first to fourth ball screws 262a to 262d. 4 moving blocks 263a through 263d and the first through fourth moving blocks 263a through 263d and is freely movable in a direction intersecting the moving direction of the first through fourth moving blocks 263a through 263d First to fourth fixing blocks 265a to 264d which are respectively fixed to the upper surface of the first to fourth intersecting blocks 264a to 264d and the lower surface of the stage 210, To 265d.

The first to fourth drive motors 261a to 261d are independently controlled by a control unit (not shown). That is, when the degree to which the master M vacuum-attracted on the stage 210 with respect to the dispenser 310 is deflected in the X-axis, Y-axis, and the? -Axis directions is calculated, the control unit controls the first to fourth driving motors 261a 261d are independently controlled so that the stage 210 can be moved through the movement of the first to fourth moving blocks 263a to 263d and the first to fourth intersecting blocks 264a to 264d.

For stable movement of the first to fourth moving blocks 263a to 263d, a plurality of first to fourth moving blocks 263a to 263d for guiding the movement of the first to fourth moving blocks 263a to 263d are formed on the upper surface of the stage supporting frame 231, And guide rails 266a through 266d are provided.

Accordingly, the first to fourth moving blocks 263a to 263d, which move along the longitudinal direction of the first to fourth ball screws 262a to 262d by the rotation of the first to fourth ball screws 262a to 262d, The first to fourth guide rails 266a to 266d can be stably moved along the first to fourth guide rails 266a to 266d.

As described above, the first to fourth moving blocks 263a to 263d are moved by the operation of the first to fourth driving motors 261a to 261d. However, unlike the first to fourth moving blocks 263a to 263d, the first to fourth intersecting blocks 264a to 264d are freely moved on the first to fourth moving blocks 263a to 263d.

6 and 7, a plurality of protrusions 269a protruding upward from the upper surface of the first moving block 263a and having a through hole 268a formed therein, Is further movably coupled to the projection 269a to pass through the first intersection block 268a and is further provided with a movement axis 270 at least a portion of which is fixed to the first intersection block 264a.

The stage 210 can be more stably supported by arranging the first to fourth stage unit alignment units 260a to 260d in the four corners of the stage support frame 231 in a rectangular configuration.

However, since the stage 210 is moved in the X-axis, Y-axis, and? -Axis directions as needed for the alignment operation of the master M with respect to the dispenser 310, 260d are also important factors.

In this embodiment, the first through fourth ball screws (260a through 260d) formed in the first through fourth unit alignment units 260a through 260d are formed so that the stage 210 can be moved in the X axis, Y axis, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, 262d, And the first to fourth drive motors 261a to 261d provided in the first and second drive motors 261a to 261d are positioned opposite to each other.

This structural feature allows the stage 210 to be easily moved in the X-axis, Y-axis, and the &thetas; axis directions (see FIGS. 8 to 10), thereby making the alignment operation for the dispenser 310 more efficient .

Hereinafter, the alignment operation of the master M with respect to the dispenser 310 based on the primary alignment marks P1 and secondary alignment marks P2 on the master M photographed by the alignment vision unit 330 The following is an explanation.

8, when the stage 210 is to be moved a predetermined distance in the right (X-axis) direction, the controller operates the first and third driving motors 261a and 261c to move the first and third balls The screws 262a and 262c are rotated in one direction. At this time, the second and fourth drive motors 261b and 261d are not operated.

Therefore, the first and third moving blocks 263a and 263c coupled to the first and third ball screws 262a and 262c are moved along the first to third guide rails 266a and 266c under the first and third ball screws 262a and 262c, respectively, And is moved in the right (X-axis) direction as shown.

At this time, although the first and third moving blocks 263a and 263c and the second and fourth moving blocks 263b and 263d located in the diagonal direction are fixed, the upper and the lower ends of the second and fourth moving blocks 263b and 263d The second and fourth intersection blocks 264b and 264d provided on the first and second movable blocks 263b and 263d move freely to the right.

By such a series of operations, the stage 210 is moved in the right (X-axis) direction as shown in Fig.

At this time, the first and third moving blocks 263a and 263c positioned in the diagonal direction from the second and fourth moving blocks 263b and 263d are fixed, but the upper and lower ends of the first and third moving blocks 263a and 263c The first and third intersection blocks 264a and 264c provided on the first and third moving blocks 263a and 263c move freely upward.

By such a series of operations, the stage 210 is moved in the upward direction (Y axis) as shown in Fig.

10, when the stage 210 is rotated clockwise by a predetermined angle (theta axis), the control section operates all of the first to fourth drive motors 261a to 261d.

When the first to fourth driving motors 261a to 261d are operated, the first to fourth moving blocks 263a to 263d are driven by the first to fourth ball screws 262a to 262d rotating in one direction And the first to fourth intersecting blocks 263a to 263d are freely moved in the corresponding directions on the first to fourth moving blocks 263a to 263d so that as shown in Figure 10, So that the rotating shaft 210 can be rotated clockwise by a predetermined angle. As such, the rotation operation of the stage 210 as in Fig. 10 can be realized by appropriately combining the operations of Figs. 8 and 9. Fig.

As described above, when the dispenser 310 is moved relative to the dispenser 310 to align the dispenser 310 and the master M and the resin for the imprint pattern is applied to the imprint pattern circle M1 of the master M The master M is moved in the direction of the web pressing portion 500 by the stage portion 200. Then,

In this embodiment, the web pressing portion 500 allows the web F to form an imprint pattern while the stage 210 on which the master M is placed passes under the web F.

The roll-to-roll module 400 for unwinding or rewinding the web F is first described and then the web pressing portion 500 of the imprint forming module 600 I will explain.
