The present invention relates to an LCD glass cleaning device, and more particularly, by constructing a bidirectional cleaning mechanism for repeatedly operating the disk brush for cleaning the LCD glass in the forward and reverse directions, compared to the conventional unidirectional cleaning device that rotates only on one side. It relates to an LCD glass cleaning device that can maximize the cleaning effect.

Generally, glass used for flat panel displays, photo masks, LCD monitors, and the like is manufactured through a process such as photosensitive agent coating, exposure, development, corrosion, peeling, cleaning, and drying.

In these processes, the cleaning process is a process of removing foreign matters, etc., from the glass using a cleaning liquid.

Glass is usually made of glass and is easily damaged or broken.

In particular, the surface is damaged by foreign matter such as dust and the like, and scratches are likely to occur.

Therefore, the cleaning process for removing foreign matters and the like adhering to the surface of the glass is a very important process for determining the quality of the product.

1 and 2 are schematic plan and side views showing a conventional LCD glass cleaning apparatus.

At this time, each of the disk brushes 12 is unidirectionally rotated to receive power simultaneously by one belt 14 and rotate in one direction.

However, the conventional cleaning device has a disadvantage in that the foreign matter removal efficiency of the glass surface is reduced since the disk brush rotates in only one direction.

In other words, the disk brush rotates in only one direction, thereby cleaning the surface of the glass, thereby limiting the cleaning efficiency. In order to compensate for this, a method of adding a disk brush arranged in the longitudinal direction of the glass may be used. However, in this case, not only the installation cost increases but also a problem of inferior economic efficiency because a larger space is required for the cleaning process.

In addition, the transmission means further comprises a guide device for guiding the linear reciprocating operation of the rack gear.

In addition, the transmission means is composed of a worm wheel mounted on the shaft of each disk brush and a worm that is arranged in engagement with each of the worm wheels to rotate the worm wheel in both directions while rotating in the forward and reverse directions, the worm Drive motor connected to one end of the power supply is characterized in that the forward and reverse motor.

In addition, the transmission means is formed on the upper end of the disk brush and a protruding bearing support having a curved bearing contact portion, connected to the axis of the drive motor is disposed across the width direction of the conveyor bearing support portion each disk brush It characterized in that it is composed of a plurality of cam / bearing assembly eccentrically bound to each other.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 are a schematic plan view and a side view showing an embodiment of the LCD glass cleaning apparatus according to the present invention.

As shown in Figures 3 and 4, it shows an example in which a transmission means consisting of a rack and pinion combination is applied.

A plurality of disk brushes 12 are arranged side by side at a predetermined interval along the width direction on the conveyor 10 for conveying the glass 11, the pinion gear 17 on the axis of each disk brush 12 Each is equipped.

At this time, each of the disk brushes 12 is supported as a rotatable structure on the frame structure as before.

In order to rotate each disk brush 12, one rack gear 18 is arranged between two rows of disk brushes 12 in parallel with the width direction of the conveyor 10 and simultaneously with the respective disk brushes 12. Interlocked.

One end of the rack gear 18 is thus connected is connected to the connecting rod 20 side to be described later, the other end is supported while being accommodated in the guide device 21 that can perform the local area and guide role at the same time, The rack gear 18 may have a structure in which both ends are supported as a whole.

The guide device 21 can be applied to a kind of block-type means having a groove portion that can accommodate a part of the rack gear 18 while being installed on the frame structure.

That is, during the linear reciprocation of the rack gear 18, the end of the rack gear 18 may be guided in a form in which the end of the rack gear 18 is received or drawn out in the groove of the block.

In addition, a disc-shaped electric wheel 19 is mounted on a shaft of the drive motor 16 provided on one side of the conveyor 10, and one side of the electric wheel 19, for example, one side of the edge and the rack gear. The connecting rod 20 is connected and installed between one end of the 18.

At this time, both ends of the connecting rod 20 have a pin coupling structure to accommodate the interference between the rotary motion and the linear motion.

Accordingly, when the driving motor 16 is operated, the rotation of the electric wheel 19 is transmitted to the rack gear 18 via the connecting rod 20, thereby allowing linear reciprocation of the rack gear 18.

That is, the rack gear 18 performs one linear reciprocating motion while the electric wheel 19 is rotated once.

Figures 5a and 5b is a schematic plan view showing the operating state of the cleaning device having a drive means of the rack and pinion combination as described above.

As shown in FIGS. 5A and 5B, when the glass 11 traveling along the conveyor 10 enters the working area of the disk brush 12, the glass 11 is rotated on the surface of the glass 11 by the rotation of the disk brush 12. Foreign matter can be removed.

At this time, the electric wheel 19 and the connecting rod 20 is operated by the operation of the drive motor 16, and the rack gear 18 is to repeat the linear reciprocating motion along the width direction of the conveyor 10 Each of the pinion gears 17 engaged with the rack gear 18 is repeatedly rotated in both directions, for example, clockwise and counterclockwise, in accordance with the linear reciprocation of the rack gear 18.

As a result, the disk brush 12 integrally rotating with the pinion gear 17 also rotates in both directions to remove foreign matters on the surface of the glass 11.

For example, as shown in FIG. 5A, when the rack gear 18 moves upward in the direction of the arrow, the first row of disk brushes 12 rotate counterclockwise while the second row of disk brushes 12 are clockwise. Direction, and on the contrary, when the rack gear 18 moves downward in the direction of the arrow as shown in FIG. 5B, the first row of disk brushes 12 rotate clockwise and the second row of disk brushes 12 half. Since it rotates in a clockwise direction, each of the disc brushes 12 is repeatedly rotated in both directions.

Thus, since the disk brush 12 rubs the glass 11 repeatedly in both directions, it is possible to clean the glass 11 more effectively than the conventional wiping in only one direction.

6 and 7 are schematic plan and side views showing another embodiment of the LCD glass cleaning apparatus according to the present invention.

As shown in Figures 6 and 7, here shows an example of applying a transmission means consisting of a combination of a worm and a worm wheel.

A plurality of disk brushes 12 are arranged side by side at a predetermined interval along the width direction on the conveyor 10 for the transfer of the glass 11, the worm wheel 22 on the axis of each disk brush 12, respectively Is mounted.

At this time, the respective disk brushes 12 are also supported in a rotatable structure on the frame structure as above.

The motor 16 is applied to the forward and reverse motor capable of forward and reverse operation.

Accordingly, when the driving motor 16 operates in the forward direction, the worm 23 also rotates in the forward direction (clockwise), while the worm wheels 22 in the first front row rotate in the reverse direction (counterclockwise) and at the same time in the rear second row. The worm wheels 22 rotate in the forward direction (clockwise). When the driving motor 16 operates in the reverse direction, the worm 23 also rotates in the reverse direction (counterclockwise), and the respective worm wheels 22 rotate in opposite directions. It turns into the rotation.

Therefore, the disk brush 12 which is integrally rotated with the worm wheel 22 also removes foreign substances, etc., deposited on the surface of the glass 11 while repeatedly rotating in both directions, and thus the disk brush 12 repeatedly scans in both directions. 11), the more effective glass cleaning can be done.
