In fig. 1, 2, and 3, the direction of arrow F is defined as the conveyance direction of the glass substrate G.
For convenience, in the following description, a direction perpendicular to the up-down direction and the front-back direction is defined as a width direction of the cleaning apparatus 1 for the glass substrate G.
For convenience of understanding, the relationship between the glass substrate G and the cleaning apparatus 1 shown in fig. 1 to 3 will be described as a size thicker than usual.
As shown in fig. 1, a cleaning apparatus 1 for a glass substrate G (hereinafter, simply referred to as a cleaning apparatus 1) according to the present embodiment is an apparatus for cleaning both surfaces (front and back surfaces) of a glass surface of a glass substrate G by driving a cleaning member to rotate by a rotary drive mechanism while conveying the glass substrate G in a conveying direction.
The cleaning apparatus 1 is, for example, an apparatus for cleaning both surfaces (front and back surfaces) of a glass surface of a rectangular glass substrate G which is arranged on a conveyance path of a conveyance apparatus of a manufacturing apparatus (not shown) of the glass substrate G and is conveyed by the conveyance apparatus from an upstream side to a downstream side in a conveyance direction (from a right side to a left side in the drawings in fig. 1 and 2) in a horizontal state (including an inclined state of 0 to 10 °).
A processing device (not shown) for performing various processes such as cutting and edge processing on the glass substrate G is provided upstream of the cleaning device 1, and an inspection device (not shown) for performing inspection of the glass substrate G is provided downstream of the cleaning device 1. The entire apparatus including the processing apparatus, the cleaning apparatus 1, the inspection apparatus, and the like constitutes a manufacturing apparatus of the glass substrate G.
The cleaning apparatus 1 is an apparatus for performing a cleaning process for removing foreign substances such as fine glass powder and dust adhering to the front and back surfaces of the glass surface of the glass substrate G through various processing steps provided on the upstream side.
As shown in fig. 1 and 2, the cleaning apparatus 1 includes an upstream roller brush cleaning section 10, a disk cleaning section 20, a downstream roller brush cleaning section 30, a flushing section 40, and a conveying section 50 in this order from the upstream side in the conveying direction. The cleaning apparatus 1 carries the glass substrate G in the carrying direction by a plurality of carrying rollers 2 provided in the carrying section 50, and performs the processes of the respective parts of the upstream side roller brush cleaning section 10, the tray cleaning section 20, the downstream side roller brush cleaning section 30, and the rinsing section 40. In the present embodiment, any number of driving rollers 2a and driven rollers are provided in the plurality of conveyance rollers 2.
in the cleaning apparatus 1 shown in fig. 1, a plurality of conveying rollers and a liquid supply mechanism (for example, a nozzle) described later, which are disposed on the lower surface side of the glass substrate G shown in fig. 2, are omitted, and a plurality of cleaning members, pinch rollers, press rollers, and the like, which are disposed on the upper surface side of the glass substrate G, are illustrated.
the glass substrate G processed by the glass substrate G processing apparatus (not shown) is conveyed in the horizontal direction along the conveying direction indicated by the arrow F by the conveying apparatus provided in the manufacturing apparatus, and is sent to the upstream roll brush cleaning section 10 provided on the upstream side of the cleaning apparatus 1.
The upstream roll brush cleaning unit 10 includes: an upper side roller brush 11; a lower side roller brush 12; press rollers 13, 13 disposed opposite to each other in the vertical direction with respect to the glass substrate G; a rotation driving mechanism (not shown) for driving the upper roller brush 11, the lower roller brush 12, and the press rollers 13, 13 to rotate, respectively; and a liquid supply mechanism 3.
The upper roller brush 11 is a cleaning member for cleaning the upper surface (front surface) of the glass substrate G. As shown in fig. 2, the upper roller brush 11 rotates in the direction of arrow a, which is the direction opposite to the conveyance direction of the glass substrate G.
The lower roller brush 12 is a cleaning member for cleaning the lower surface (back surface) of the glass substrate G. The lower roller brush 12 is disposed to face the upper roller brush 11, and as shown in fig. 2, the lower roller brush 12 rotates in the direction of arrow B, which is the direction opposite to the conveyance direction of the glass substrate G.
The upper roller brush 11 and the lower roller brush 12 are positioned above and below the glass substrate G of the glass substrate G, and are arranged such that the respective rotation shafts 11a and 12a are vertically aligned. That is, the upper roller brush 11 and the lower roller brush 12 are arranged in a pair on the upper surface side (front surface side) and the lower surface side (back surface side) of the glass substrate G. The pair of upper roller brush 11 and lower roller brush 12 is configured to sandwich the glass substrate G in the thickness direction. The upper roller brush 11 and the lower roller brush 12 have the same diameter and the same length in the width direction. The upper roller brush 11 and the lower roller brush 12 are rotated by the rotation driving mechanism around respective rotation shafts 11a and 12a extending in the width direction of the glass substrate G, and thereby the entire width of the upper surface and the lower surface of the glass substrate G can be cleaned.
The press rollers 13 and 13 are disposed upstream and downstream of the upper roller brush 11 and the lower roller brush 12 in the conveyance direction, and sandwich the glass substrate G in the width direction on both surfaces of the glass substrate G. The press roller 13 includes a rotating shaft portion 13a extending in the width direction of the glass substrate G, and a columnar contact portion 13b which is in contact with the glass substrate G, has a diameter larger than the rotating shaft portion 13a, and is longer than the width dimension of the glass substrate G. The outer peripheral surface of the contact portion 13b serves as a contact surface with the glass substrate G.
The press rollers 13, 13 are disposed on the upstream side and the downstream side in the conveyance direction of the upper roller brush 11 and the lower roller brush 12, and sandwich the glass substrate G between the contact portions 13b, 13b of the press rollers 13, 13 from above and below. The press rollers 13 and 13 are rotated in the same direction as the conveyance direction by the rotary drive mechanism while sandwiching both surfaces of the glass substrate G, so as to stably convey the glass substrate G in the conveyance direction. Accordingly, even when the upper roller brush 11 and the lower roller brush 12 are rotated in the direction opposite to the conveying direction of the glass substrate G, since the glass substrate G is sandwiched by the press rollers 13 and 13, deformation of the glass substrate G such as deflection can be suppressed and a good cleaning performance can be maintained.
A plurality of liquid supply mechanisms 3 are disposed along the transport path so as to face the upper and lower sides of the glass substrate G, and supply, as a cleaning liquid, for example, pure water, water mixed with a detergent, or the like to the upper surface side and the lower surface side of the glass substrate G.
The liquid supply mechanism 3 is provided above and below the glass substrate G at each of the upstream roller brush cleaning unit 10, the disk cleaning unit 20, and the downstream roller brush cleaning unit 30.
the glass substrate G cleaned by the upstream roll brush cleaning unit 10 is conveyed from the upstream roll brush cleaning unit 10 to the tray cleaning unit 20 by the conveying unit 50.
The disk cleaning unit 20 includes: a plurality of cleaning members 21, 21 … … in a disk shape; rotary shafts 22, 22 … … supporting the plurality of cleaning members 21, 21 … …, respectively; a rotation driving mechanism (not shown) for driving the rotation shafts 22 and 22 … … …, respectively; and the liquid supply mechanism 3 described above.
The cleaning member 21 has a cleaning pad (not shown) made of an elastic body disposed to face the glass surface of the glass substrate G. The cleaning members 21 and 21 … … are arranged in a plurality of rows (two rows in the present invention) along the width direction of the glass substrate G. The plurality of cleaning members 21 and 21 … are arranged to face each other in the vertical direction with the glass substrate G interposed therebetween, in order to clean the front and back surfaces (upper and lower surfaces) of the glass surface of the glass substrate G.
The disk cleaning unit 20 can clean the upper and lower surfaces of the glass substrate G by bringing a cleaning pad of the cleaning member 21 into contact with the glass substrate G conveyed by the conveying unit 50, and supplying a cleaning liquid to the upper and lower surfaces of the glass substrate by the liquid supply mechanism 3 to rotationally drive the glass substrate G. The disk cleaning unit 20 may be configured to provide a supply hole for the cleaning liquid on the rotation center axis of the cleaning member 21 instead of the liquid supply mechanism 3, and to supply the cleaning liquid from the rotation axis 22.
further, by providing the disk cleaning unit 20 with the cleaning member 21 which is a disk-shaped pad having a shape different from that of the roller brush, various stains adhering to the glass substrate G can be efficiently removed.
After the cleaning of the tray cleaning unit 20, the glass substrate G is conveyed from the tray cleaning unit 20 to the downstream roller brush cleaning unit 30 by the conveying unit 50.
The downstream side roller brush cleaning unit 30 includes: an upper side roller brush 31; a lower side roller brush 32; pinch rollers 33, 33 as both end holding parts; a rotation drive mechanism (not shown) for driving the upper roller brush 31, the lower roller brush 32, and the pinch rollers 33 and 33 to rotate, respectively; drive rollers 2a, 2a disposed opposite to the pinch rollers 33, respectively; and a liquid supply mechanism 3.
the upper roller brush 31 is a cleaning member for cleaning the upper surface (front surface) of the glass substrate G. As shown in fig. 2 and 3, the upper roller brush 31 rotates in the direction of arrow a, which is the direction opposite to the conveyance direction of the glass substrate G.
The lower roller brush 32 is a cleaning member for cleaning the lower surface (back surface) of the glass substrate G. The lower roller brush 32 is disposed to face the upper roller brush 31, and rotates in the direction of arrow B, which is the direction opposite to the conveyance direction of the glass substrate G, as shown in fig. 2 and 3.
The upper roller brush 31 and the lower roller brush 32 are positioned above and below the glass substrate G, and are disposed such that the respective rotation shafts 31a and 32a are vertically aligned. That is, the upper roller brush 31 and the lower roller brush 32 are arranged in a pair on the upper surface side (front surface side) and the lower surface side (back surface side) of the glass substrate G. The pair of upper roller brush 31 and lower roller brush 32 is configured to sandwich the glass substrate G in the thickness direction. The upper roller brush 31 and the lower roller brush 32 have the same diameter and the same length in the width direction. The upper roller brush 31 and the lower roller brush 32 are rotated by the rotation driving mechanism around respective rotation shafts 31a and 32a extending in the width direction of the glass substrate G, and thereby the entire width of the upper surface and the lower surface of the glass substrate G can be cleaned.
the pinch rollers 33 and 33 are disposed on the upstream side and the downstream side in the conveyance direction of the upper roller brush 31, and press both end portions in the width direction on the upper surface side of the glass substrate G downward. The pinch roller 33 includes a rotating shaft 33a extending in the width direction of the glass substrate G, and contact portions 33b, 33b which are in contact with the glass substrate G and have a disk shape with a diameter larger than that of the rotating shaft 33 a. The outer peripheral surface of the contact portion 33b serves as a contact surface with the glass substrate G.
The pinch rollers 33, 33 are in a form in which the drive rollers 2a, 2a of the conveyance unit 50 are disposed at positions facing each other with the glass substrate G interposed therebetween, and the glass substrate G is sandwiched from above and below by the contact portion 33b of the pinch rollers 33, 33 and the drive rollers 2a, 2 a. The pinch rollers 33 and 33 are rotated in the same direction as the conveyance direction by the rotary drive mechanism while pressing the upper surface of the glass substrate G, so that the glass substrate G is stably conveyed in the conveyance direction. Accordingly, even when the upper roller brush 31 and the lower roller brush 32 are rotated in the direction opposite to the conveying direction of the glass substrate G, the upper surface of the glass substrate G is pressed downward by the pinch rollers 33 and 33, and therefore, deformation such as deflection of the glass substrate G can be suppressed and a good cleaning performance can be maintained.
Further, since the pinch rollers 33 and 33 are in contact with only a part of the glass substrate G in the width direction, there is an advantage that it is difficult to add a roller mark generated by the contact to the upper surface side (effective surface side).
In the present embodiment, the two pinch rollers 33 are disposed on the upstream side and the downstream side of the upper roller brush 31 in the conveying direction, but the effect of the invention can be achieved even when disposed on at least one of the upstream side and the downstream side.
The contact pressure of the pinch rollers 33, 33 with respect to the glass substrate G is higher than the contact pressure of the upper roller brush 11 and the lower roller brush 12 with respect to the glass substrate G. Accordingly, even if the glass substrate G attempts to be deformed by the rotation of the upper roller brush 31 and the lower roller brush 32, the glass substrate G can be stably conveyed against the force.
The pinch rollers 33 and 33 are integrally provided at predetermined positions above the conveying unit 50. Thus, the pinch rollers 33 and 33 are integrated with the conveyance unit 50, and therefore, the pinch rollers 33 and 33 can be easily positioned with respect to the glass substrate G.
When the thickness of the glass substrate G is 0.2mm or more, the rotation direction of the upper roller brush 31 and the lower roller brush 32 is preferably the reverse rotation direction with respect to the conveyance direction of the glass substrate G.
On the other hand, when the thickness of the glass substrate G is less than 0.2mm, it is preferable to appropriately change the rotation direction of the upper roller brush 31 and the lower roller brush 32 for one glass substrate G. Specifically, it is preferable that, after the upstream end of the glass substrate G being conveyed enters between the upper roller brush 31 and the lower roller brush 32, the rotation direction of the upper roller brush 31 and the lower roller brush 32 is the same as the conveyance direction of the glass substrate G before the upstream end of the glass substrate G reaches 20mm in the conveyance direction from the respective rotation shafts 31a and 32a of the upper roller brush 31 and the lower roller brush 32, and the rotation direction is reversed from 20mm and thereafter, and the rotation direction is set to be the reverse of the conveyance direction of the glass substrate G.
Accordingly, when the upstream end of the glass substrate G enters between the upper roller brush 31 and the lower roller brush 32, the glass substrate G can be smoothly guided between the upper roller brush 31 and the lower roller brush 32, and when a predetermined length (for example, 20mm) is sandwiched between the upper roller brush 11 and the lower roller brush 12, the rotation direction is reversed to improve the cleaning ability, and the rotation direction is reversed with respect to the conveyance direction of the glass substrate G, thereby improving the cleaning ability.
After the cleaning of the glass substrate G by the downstream side roller brush cleaning unit 30, the glass substrate G is conveyed from the downstream side roller brush cleaning unit 30 to the rinsing unit 40 by the conveying unit 50.
The rinse unit 40 includes a plurality of nozzles 4 as liquid supply mechanisms for spraying rinse liquid toward the upper and lower surfaces of the glass substrate G conveyed by the conveyance unit 50. This enables the glass substrate G to be washed and removed of dirt and the like adhering thereto by spraying the rinse liquid from the nozzle 4 during cleaning. As the rinse liquid, for example, pure water, water mixed with a detergent, or the like can be used.
The conveying unit 50 includes: a conveyance roller 2 having a plurality of driving rollers 2a and driven rollers; and a rotation driving mechanism (not shown) for driving the driving roller 2a to rotate. The conveying unit 50 can convey the glass substrate G in the horizontal direction by rotationally driving the rotational driving mechanism. The conveying rollers 2 may be all the drive rollers 2 a.
As described above, according to the present invention, even when the roller brush is rotated in the direction opposite to the conveying direction of the glass substrate, the glass substrate can be prevented from being deformed such as bent, and a good cleaning performance can be maintained.
