Description

[0001] The present invention relates to a polishing apparatus of a glass plate,

The present invention relates to a glass plate polishing apparatus, and more particularly, to a glass plate polishing apparatus which is provided with a spray hole formed in the center of a rotation axis of a motor to penetrate the spray hole along a longitudinal direction of the axis, The polishing liquid is sprayed directly to the portion to be processed in the glass through the spray hole of the rotary shaft and the guide hole of the polishing member so as to be polished so that the polishing efficiency against the glass is remarkably improved and at the same time, And to simplify the structure.

In addition, when the upper and lower protective members are fixedly installed on the outer side of the motor and the lower cover, the rotating shaft is pierced and coupled so that the upper and lower protective members are prevented from flowing into the motor when the polishing liquid splashes toward the motor. Thereby preventing the bearing and the seal coupled to the rotating shaft from being damaged by the polishing liquid.

It is also possible to provide a structure in which magnets are provided on the adapter and ring mass constituting the abrasive member and adhered to and separated from each other by adhesion and dehydration so that the ring velcro and the hook velcro are respectively attached to and separated from the ring mass and the polishing portion, The present invention relates to a glass plate polishing apparatus which can remarkably improve the convenience of replacing the polishing section by allowing the polishing section to be easily separated from the ring mass to be exchanged.

Generally, a polishing apparatus polishes a polishing pad with a polishing pad while supplying the polishing liquid to a glass. Such a polishing apparatus has a complicated structure because the polishing liquid injection nozzle is arranged outside the polishing pad and is injected, The bearing and the seal coupled to the rotating shaft constituting the motor are easily damaged, and the polishing pad is assembled to the rotating shaft, which is inconvenient when exchanging work. Therefore, in recent years, .

On the other hand, the prior art KR 10-1490458 B1 2015.1.30. "Curved surface window glass inner diameter and planar grinder of mobile device"

A vacuum suction pipe 62 is connected to a jig 111 for fixing a glass on a table 112 of a polishing machine and a motor 221 for lifting and lowering the polishing jig 111 is mounted on the jig 111, And a polishing liquid jetting nozzle 32 is disposed outside the polishing jig 211. The polishing liquid jetting nozzle

After the glass is mounted on the jig 111 as described above and fixed with vacuum air pressure, the motor 221 is operated to lower the polishing jig 211 to the front surface of the glass while rotating the polishing jig 211, And the polishing liquid is sprayed onto the glass.

Therefore, the polishing jig 211 is polished with a polishing liquid.

Such a conventional technique has a problem in that the structure of the polishing machine is complicated because the injection nozzle is arranged outside the polishing jig 211 and the movement of the polishing pad and the jetting nozzles are inconsistent to achieve a uniform quality .

Another problem is that when the abrasive liquid is sprayed, it is splashed in the polishing process, and a part thereof flows into the motor 221, at which time the bearings and seals coupled to the rotation shaft are damaged by the abrasive liquid.

Another problem is that the polishing pad 211 is assembled with the polishing pad 211, which makes it difficult to separate and assemble the polishing pad.

The polishing unit 130 includes a hook hole 128, a sponge 132 and a polishing pad 134. The guide hole 56 is formed at the center of the hook hole 128, But the present invention is not limited thereto.

Hereinafter, the operation of the present invention will be described.

First, when the cylinder 24 is operated to perform the polishing operation on the glass 2 fixed to the jig 6 (see FIG. 2), the rod 26 is advanced and the moving plate 18 is pushed The move sleeve 16 descends along the guide rod 12 with the motor 20 coupled to the lower end of the move sleeve 16 and the housing 28 of the motor 20 moves down And goes down through the guide hole 11 of the table 10.

The polishing member 54 coupled to the distal end of the rotary shaft 34 is lowered onto the glass 2 in the course of descending of the motor 20 as described above, A part of the cleaning liquid 28 passes through the cleaner 92 coupled to the ring 88 of the cleaning member 62 (see FIG. 6B).

The motor 20 is operated to rotate the rotary shaft 34 together with the abrasive member 54 in accordance with the information transmitted from the inverter 46 The cap 66 of the protection member 58 and the cap 76 of the lower protection member 60 are coupled together by the set screws 72 and 86 and rotate together.

As described above, the rotation speed of the motor 20 is controlled by the inverter 46 from 1200 rpm to 2400 rpm during the operation of the motor 20, but is not limited thereto.

The polishing liquid supplied from the polishing liquid supply device 52 passes through the rotary joint 50 and moves along the injection hole 48 of the rotary shaft 34 and then passes through the guide hole 56 of the abrasive member 54, And the polishing pad 134 is polished with the polishing liquid.

As described above, in the process of polishing the glass 2 by the polishing pad 134, the abrasive liquid sprayed on the polishing pad splashes to the top and the bottom of the table 10 while scattering in four directions. 60 and the housing 28 of the motor 20, as shown in Fig.

A part of the polishing liquid splashed toward the upper protective member 58 moves down while hitting against the outer peripheral wall surface of the cap 66 and then the polishing liquid is supplied to the upper portion of the flange 68 and the upper cover 30 ), And then falls downward.

At the same time, some of the abrasive liquid flows into the interior of the upper protective member 58 through the gap between the cap 66 and the flange 68. However, the abrasive liquid is supplied to the sleeve 70 inserted from the inside of the cap 66 to the upper side, And then flows out through the gap between the cap 66 and the flange 68 again.

Accordingly, since the abrasive liquid splashing as described above can not enter the inside of the housing 28 along the rotation axis 34 of the motor 20, the rotation shaft 34 and the bearing (not shown) 36 and the seal 38 are protected from being damaged by the polishing liquid.

Part of the polishing liquid splashed toward the lower protective member 60 (see FIG. 5B) flows down and falls down against the outer wall of the block 78 of the body 74, and at the same time, The polishing liquid is mostly returned to the outside but partially moved upward along the inner circumferential surface of the inner sleeve 80, and then the inner circumferential surface of the inner sleeve 80 is moved upward, And moves along the outer peripheral surface of the sleeve 80 to reach the bottom surface of the U-shaped groove 82.

Thereafter, the polishing liquid is dropped from the U-shaped groove 82 through the orifice 84 to the outside of the block 78 and falls downward.

Therefore, the abrasive liquid that splashes while being scattered can not enter the block 78 along the rotation axis 34 of the motor 20, so that the rotation of the rotary shaft 34 and the bearing (not shown) 36 and the seal 38 are protected from being damaged by the polishing liquid.

A part of the polishing liquid splashed toward the cleaning member 62 (see FIG. 6A) is applied to the outer peripheral surface of the housing 28 of the motor 20 exposed below the table 10, The polishing liquid on the outer circumferential surface of the housing 28 is upwardly raised on the table 10 while being cleaned by the cleaner 92 provided on the cleaning member 62 in the process of the upward movement of the motor 20. [

Therefore, the housing 28 of the motor 20 located below the cleaner 92 is still in the state of being abraded with the polishing liquid, and the housing 28 located above the table 10 is polished with the polishing liquid.

8A, when the polishing liquid splashes toward the bellows 186 formed of another embodiment, the polishing liquid is applied to the outer surface of the bellows 186, and the polishing liquid, which is located inside the bellows 186, The abrasive liquid does not adhere to the member 62 and the housing 28 of the motor 20 and the lower protection member 60 and the like.

At this time, when the motor 20 is moved up and down, the bellows 186 is folded as shown in FIG. 8A, and the bellows 186 is unfolded as shown in FIG. 8B.

A part of the polishing liquid flows into the block 78 constituting the lower protective member 60 along the rotary shaft 34 and then is discharged through the orifice 84 of the block 78 At this time, as shown in FIG. 8C, the polishing liquid is discharged to the outside through the discharge hole 188 located in the lower part of the bellows 186 formed in another embodiment.

7A), a part of the abrasive liquid splashes toward the adapter 94. This abrasive liquid is applied to the block 96 (FIG. 7A) constituting the adapter 94 And then the polishing liquid flows through the orifice 114 to the inside of the block 96 through the gap of the block 96 in which the lateral groove 104 or the rotational axis 34 of the block 96 is coupled. And exits to the outside.

The abrasive liquid flowing into the coupling groove 102 escapes to the outside due to the centrifugal force of the adapter 94 rotating together with the rotation shaft 34. Thus, the abrasive liquid quickly escapes from the adapter 94.

Meanwhile, when a large amount of glass 2 is polished with the polishing member 54, the function of the polishing pad 134 is deteriorated. In this case, the process of exchanging the polishing member 54 will be described.

When the ring mass 122 constituting the abrasive member 54 is pulled and separated from the adapter 94, the magnets 120 installed on the ring mass 122 and the magnets 120 installed on the adapter 94, And at the same time the projection 124 of the ring mass 122 is released from the coupling groove 102 of the adapter 94. [

After that, when the polishing unit 130 is pulled to separate from the ring mass 122, the hook velcro 128 of the polishing unit 130 is separated from the ring velcro 126 provided in the ring mass 122 .

When the hook part 128 constituting the new part 130 is attached to the hook hook part 126 after the used part 130 is removed and the hook part 130 is attached to the ring part 122, As shown in Fig.

The protrusion 124 of the ring mass 122 is inserted into the coupling groove 118 of the adapter 94 so that the magnet 120 of the ring mass 122 is inserted into the magnet 120 of the adapter 94, So that the replacement operation of the new polishing unit 130 is completed.

Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the disclosed embodiments.
