The present invention relates to a coupling structure of a roll flange and a spindle in a rubbing device. In particular, the present invention is to install the roll flanges on both ends of the rubbing rollers, and the separation of the rubbing rollers to the roll head by allowing the spindle to be coupled to the roll flange in the state supported by the roll head to move in the longitudinal direction of the rubbing rollers In particular, the roll flange and spindle of the rubbing roller can be used for cemented carbide or cold die alloy tool steel (SKD11), high speed tool steel (HSS), high-speed oral steel (SKHS), and high-speed steel for cutting hard-working materials (SKH10). The present invention relates to a coupling structure between a roll flange and a spindle in a rubbing device which is formed of a material having high wear resistance such as a roll flange that transmits rotational force to a rubbing roller and induces a stable coupling state with the spindle.

In general, a liquid crystal display device forms a liquid crystal layer between two glass substrates, and on the inner surface of the two glass substrates, a transparent electrode for applying an electric field to the liquid crystal layer, a switching element for turning the electric field on / off, and a color display The color filter and the alignment film for orientating a liquid crystal molecule are formed, respectively. A liquid crystal material is enclosed between two glass substrates to produce a liquid crystal display element. The alignment film is made of a resin layer such as polyimide resin (PI) coated on a substrate, and the liquid crystal is aligned in a predetermined direction by rubbing treatment with a rubbing device after curing the alignment film.

A common rubbing device includes a rubbing roller with both ends rotatably supported above a stage on which a glass substrate is placed and fixed. A rubbing cloth is wound on a surface of the rubbing roller by a double-sided tape or the like. As the rubbing roller rotates, the brush is brought into contact with the surface of the alignment layer of the glass substrate, and the surface of the glass substrate is rubbed in a predetermined direction to give the same effect as the uniaxial stretching direction of the film, and to align the liquid crystal material in that direction. .

In order to maintain the luminance and responsiveness of the liquid crystal display element uniformly, it is important to rub the surface of the alignment layer uniformly in the rubbing process to give the orientation of the surface of the alignment layer so that the liquid crystal is uniformly aligned. For this reason, it is necessary to maintain the separation distance between the rubbing roller and the glass substrate, in particular, the separation distance between the rubbing roller and the alignment film on the glass substrate.

Hereinafter, the present invention will be described in detail.

Figure 1 shows a rubbing device according to the present invention, a table 2 for transferring a glass substrate to be rubbed is located at the upper center portion of the main frame (1). The table 2 is linked to a power source (not shown) to transfer the glass substrate at a fixed speed in a fixed state so that rubbing by the rubbing roller 9 can be performed while the table 2 and the rubbing roller 9, ie, The rubbing roller 9 is configured to be movable up and down in accordance with the gap between the glass substrate fixed to the table 2 and the rubbing roller 9.

Various rubbing rollers with large length differences for rubbing the substrate can be easily mounted on the spindle.

Here, when the fixed spindle support device 12b is moved in the longitudinal direction of the rubbing roller 9 by a cylinder or other power not shown, the servo motor 5 which transmits power to the spindle support device 12b is also fixed. Naturally, it should be possible to move the longitudinal direction of the rubbing roller 9 by a cylinder or other power not shown with the spindle support 12b.

2A and 2B illustrate the chucking process of the roll head, i.e., the spindle 7, and the rubbing roller 9, and the cylinder 6 for coupling the rubbing roller 9 to the roll head, i.e., the spindle 7, ) To move the movable spindle support 12a in the opposite direction to the spindle 7 as shown in FIG.

In this way, the movable spindle support device 12a is moved in the opposite direction to the direction of the spindle 7 as shown in FIG. 2B, that is, in the opposite direction to which the rubbing roller 9 is mounted, and then the rubbing roller 9 by a conveying means (not shown). ) Is aligned with the spindle 7 of the movable spindle support 12a and the spindle 7 of the fixed spindle support 12b.

Then, as the cylinder 6 is driven to move the movable spindle support device 12a in the direction in which the rubbing roller 9 is located as shown in FIG. 2A, the spindle 7 roll roll 8 of the rubbing roller 9 While coupled to the rubbing roller 9 is supported to be rotatable by the two spindle (7).

The chucking process described above is an example in which only one movable spindle support device 12a moves. Hereinafter, the chucking process when the two movable and fixed spindle support devices 12a and 12b are moved as another embodiment of the present invention will be described with reference to FIGS. 2A, 2B, and 2C.

First, in order to mount the rubbing roller 9 to the two spindles 7, a cylinder 6 and an unillustrated cylinder or power source are driven to move and fix the spindle support 12a (as shown in FIGS. 2B and 2C) ( 12b) is moved in the opposite direction that the two spindles 7 face.

In this way, the movable and fixed spindle support devices 12a and 12b are moved in the opposite direction to the front of the spindle 7, that is, in the opposite direction to which the rubbing roller 9 is mounted, and then the rubbing roller 9 by a conveying means (not shown). ) Is aligned with the spindle 7 of the movable spindle support 12a and the spindle 7 of the fixed spindle support 12b.

In addition, as shown in FIG. 2A, the movable spindle support device 12a moves in the direction in which the rubbing roller 9 is located, while the fixed spindle support device 12b is also driven by the driving of the cylinder 6 and the power source (not shown). As the 9 moves in the direction in which it is located, the two spindles 7 are coupled to the roll flanges 8 of the rubbing rollers 9 so that the rubbing rollers 9 are rotatably supported by the two spindles 7. do.

3A and 3B show a state in which the spindle 7 is mounted on the roll flange 8 of the rubbing roller 9 in the present invention, and is rotatably installed on the movable and fixed spindle support devices 12a and 12b. The spindle 7, which is separated from the roll flange 8 of the rubbing roller 9, is coupled to the shaft 13. In addition, both sides of the rubbing roller (9) is provided with a flange (8) for separate coupling with the spindle (7).

Here, the spindle 7 has an inclined surface whose diameter gradually decreases toward the direction in which it is coupled with the rubbing roller 9 in the axial direction, and the engaging groove 16 of the roll flange 8 of the rubbing roller 9 is a spindle. For smooth separation and coupling with (7) it has a feature that has an inclined surface that gradually decreases the inner diameter in the direction in which the spindle 7 is coupled.

In particular, when the spindle 7 is engaged with the engaging groove 16 of the roll flange 8, the outer circumferential surface of the spindle 7 coincides with the inner circumferential surface of the roll flange 8 engaging groove 16, so that Despite the rotation, the spindle 7 does not flow in the engagement recess 16 of the roll flange 8, thereby minimizing the friction between the spindle 7 and the roll flange 8 and also of the rubbing roller 9 The height can be kept constant.

In addition, the pin flange 15 in contact with the coupling groove 16 is formed in the roll flange 8 so as to be orthogonal to the engagement direction of the spindle 7 coupled to the coupling groove 16, and the roll flange has a roll flange at the spindle 7. Positioning pins 14 for the separate coupling with the pin groove 15 of (8) are orthogonally coupled to the engagement direction of the spindle 7, wherein the positioning pins 14 of the spindle 7 and the roll The pin groove 15 of the flange 8 allows the spindle 7 to remain engaged without slipping in the engaging groove 16 of the roll flange 8, so that the rotational force transmitted through the spindle 7 is rubbing. It serves to be delivered to the roller (9).

Here, the pin groove 15 and the positioning pin 14 coupled thereto rubbing the rotational force of the spindle 7 while minimizing frictional force when the spindle 7 is coupled to the engaging groove 16 of the roll flange 8. It is preferable that the pin groove 15 or the positioning pin 14 has a shape, shape, and number such that the pin groove 15 or the positioning pin 14 is not worn or deformed in the process of transferring to the roller 9.

In particular, the material of the spindle 7, the shaft 13, the positioning pin 14, and the roll flange 8 coupled thereto are made of cemented carbide, alloy tool steel for cold die (SKD11), and high speed tool steel (HSS). , High-speed coated oral steels (SKHS), high-speed steels for cutting hard cutting materials (SKH10), etc., can be molded into alloys with excellent wear resistance to minimize errors caused by friction or vibration between the spindle 7 and the roll flange 8 ( See Patent No. 070453, Patent No. 0594338, Patent No. 038977, Patent No. 0611201, and Patent No. 0600618).

Here, the cemented carbide is molded and sintered by adding 3 to 20% by weight of Co as a binder to powders such as WC. Types include WC-TiC-Co and WC-TiC-TaC in addition to WC-Co. The hardness and degree are adjusted according to the amount of Co. The hardness of the cemented carbide is HRA85, whereas the hardness of ordinary alloy steel is about HRA83.4. However, it should not be used in areas subject to impact because of its low viscosity.

4A, 4B and 4C show the rubbing roller 9 of the rubbing device, and an aluminum bracket 19 for fastening the roll flange 8 to both ends of the rubbing roller 9 is fastened. In order to reduce the deflection of the rubbing roller (9) on the inner surface of the rubbing roller (9) made of SUS or SUS, the reinforcing member made of CFRP (carbon reinforced plastic) material having superior rigidity and weight reduction as well as excellent shock absorption ability (17) Is implied.

Compare the amount of deflection of the rubbing roller (9) when combined with the case that does not combine the reinforcement (17) of the above CFRP material.

First, when the length of the aluminum rubbing roller is 2300 mm, the outer diameter is 130 mm, the thickness is 7 mm, and the weight is 8.6 kg, the deflection amount of the rubbing roller is 65.9 m.

Next, by combining the reinforcing material of the CFRP material on the inner surface of the rubbing roller, the length is 2300 mm, the outer diameter is 130 mm, the thickness is 7 mm, the weight is 5.4 kg, the deflection amount of the rubbing roller is 26.6 ㎛.

However, this is a data value measured without the roll flange coupled to the rubbing roller.

In other words, simply combining the reinforcement of CFRP material on the inner surface of the rubbing roller of aluminum or SUS material can be reduced to 1/3 of the deflection amount of the rubbing roller.

In addition, the middle portion of the inside of the rubbing roller 9 is made of a material such as aluminum to prevent the rubbing roller 9 from sagging due to its own weight of the rubbing roller 9 or centrifugal force caused by the rotation of the rubbing roller 9. The balance weight 18 is inherent.

Here, the materials of the rubbing roller 9, the balance weight 18, and the bracket 19 may be made of aluminum.

In order to couple the roll flange 8 of cemented carbide material to the brackets 19 on both sides of the rubbing roller 9, four bolt tabs 21 are formed at a predetermined interval on the bracket 19 so that the wrench bolt is used. Thus, the roll flanges 8 may be coupled to both sides of the bracket 19, respectively.

In addition, at the outside of the bracket 19, 36 tanned bolt tabs 20 are formed concentrically with a predetermined interval. That is, 36 tanned bolt tabs 20 are formed at intervals of 10 ° around the center of rotation of the rubbing roller 9, which are combined with tanned bolts to hold the center of gravity of the rubbing roller 9. will be.

5a to 5e show the spindle 7 coupled to the roll flange 8 of the rubbing roller 9 and the shaft 13 coupled thereto, wherein the spindle 7 and the shaft 13 are made of cemented carbide. Is done. In the coupling process of the shaft 13 and the spindle 7, the coupling protrusion of the spindle 7 is inserted into the coupling groove of the shaft 13 expanded by high temperature, and then cooled. As the groove shrinks, it is to be integrally coupled with the engaging projection of the spindle 7.

The inclined surface of the spindle 7 is formed with a pin hole 23 penetrating the center of the spindle 7, the pin hole 23 is separated from the pin groove 15 of the roll flange (8) Positioning pin 14 is coupled to.

In addition, a screw tab 24 facing the center of the spindle 7 is formed in front of the spindle 7, and the countersunk head screw 25 is coupled to the screw tab 24. At this time, the countersunk head screw 25 penetrates completely through the screw tab 24 and enters the fixing hole 26 of the positioning pin 14 coupled to the pin hole 23, so that the roll flange 8 and the spindle 7 The positioning pin 14 is not detached from the pin hole 23 even in a separate coupling with the pin.

Here, it is preferable that the angle of the inclined surface of the spindle 7 and the roll flange 8 engaging groove 16 in which the spindle 7 is separated and coupled is set to 10 to 20 degrees.

6A to 6B, the tannery bolt tab 20 of the bracket 19 shown in FIG. 6a to 6b uses a tannery bolt 27 fastened thereto to hold a center of gravity centered on the rotational center of the rubbing roller 9 to provide a rubbing roller ( In order to suppress the vibration of 9), one of the tannery bolts 27 is also manufactured without being fastened to the tannery bolt tab 20 at first.

At this time, the tannery bolt tab 20 formed on the outer side of the bracket 19 is a total of 36 are formed at regular intervals with a 10 ° interval around the rotation center of the rubbing roller 9. The tannery bolt 27 coupled to this is made of SUS or plastic material.

The vibration amount of the rubbing roller 9 produced as described above is installed at one end of the rubbing roller 9, and is detected by using the laser of the vibration sensing device, and then detected at a portion having a smaller weight than the other part. By coupling one or more bolts 27 to the formed tanned bolt tab 20 to eliminate the weight error, the vibration of the rubbing roller 9 can be adjusted to an error range.

7A to 7C show that the eccentricity of the roll flange 8 coupled to the bracket 19 of the rubbing roller 9 is measured and adjusted. The bracket 19 on both sides of the rubbing roller 9 has a roll flange ( 8) Four bolt tabs 21 for joining are formed at regular intervals, and the bolt tabs 21 are made of SUS wrench bolts 28 with roll flanges 8 on both sides of the bracket 19. It is fixed while being fixed.

In the process of adjusting the eccentricity of the rubbing roller 9, that is, the roll flange 8, first, the wrench bolt 28 is fastened to the bolt tab 21 to roll the bracket 19 of the rubbing roller 9. After the flange 8 is engaged, at least five indicator measuring units 29 are installed at the lower end of the rubbing roller 9 to measure the inclination of the rubbing roller 9, and then four wrench bolts fixing the roll flange 8. After loosening the 28, the tilt of the rubbing roller 9 is adjusted while moving the roll flange 8 of the rubbing roller 9 in a specific direction using a hammer or the like.

As described above, the process of adjusting the eccentricity of the roll flange 8 coupled to the bracket 19 of the rubbing roller 9 while tightening or releasing the wrench bolt 28 that couples the roll flange 8 to the bracket 19 is performed. It is repeated until the eccentricity error measured by each indicator measuring unit 29 is 15 microns or less.

Therefore, according to the present invention, by installing the roll flanges on both ends of the rubbing rollers, so that the spindle to be coupled to the roll flange in the state supported by the roll head can be moved in the longitudinal direction of the rubbing rollers to easily move the rubbing rollers to the roll head There is an effect that can be separated and combined.
