Description

Chamfer grinding device

The present invention is a polishing apparatus which performs chamfering processing on edges of both sides of a board surface of a substrate such as a glass substrate or a ceramic board.

In the prior art, there is a method in which the two corners of the end faces of the plate surface are chamfered by a grinding wheel (plural gangue) (refer to Patent Document 1).

Patent Document 1: Japanese Patent Laid-Open Publication No. 2007-223027.

[New Problem to be Solved] However, according to the grinding method of the prior art 1, the two corners of the end face of the plate are brought into contact with the periphery of the grinding wheel to perform chamfering.

In this way, since sludge or glass slag which is scattered with the grinding is not recovered, the sludge or glass swarf will adhere to the surface of the sheet, and thus the sludge or glass cullet must be removed in the next project. The problem.

In addition, there is a problem that the grinding portion is burnt due to an increase in temperature at the time of grinding.

In addition to the above problems, the surface of the sheet material becomes dirty, which is inconvenient to eliminate the stain, thereby deriving the problem that the washing operation must be performed in the next project.

In summary, the present invention provides a grinding apparatus that solves the above problems.

In order to solve the above problems, the present invention adopts a configuration in which a work table has an adsorption function to hold a substrate placed thereon, and a meandering vermiculite and a lower side vermiculite, the protruding portions of which are vertically engaged with each other to Grinding a plate angle of the upper and lower plate faces of the edge of the substrate protruding from the front edge of the table; first and second motors connecting the upper side vermiculite and the driving shaft of the lower side vermiculite; and a cover body covering the upper side vermiculite And the lower side vermiculite having an opening embedded in a portion of the polishing edge of the substrate; the upper nozzle and the lower nozzle, the upper and lower surfaces of the substrate edge protruding from the table, and the mixed fluid for jetting air and grinding cooling water toward the opening And a mixed fluid for washing water and air; a suction port for absorbing and guiding the inside of the cover; and a moving mechanism provided as any one of the work table or the cover body to advance and retreat in the left-right direction.

[New effect] As shown above, the polishing apparatus of the present invention inserts the polishing edge of the substrate held by the substrate held on the table from the opening into the inside of the cover. In this case, the table can be borrowed from the substrate. Moved by the moving mechanism (can also replace the workbench, so that the upper side vermiculite and the lower side meteorite move with the cover).

With this movement, the mixed fluid of the air and the cooling water, the mixed fluid of the washing water and the air are sprayed from the upper nozzle onto the upper surface of the substrate, and are ejected from the lower nozzle to the lower surface of the substrate, while the upper side vermiculite and the lower side are simultaneously The grinding protrusions that the meteorites bite to each other contact the upper and lower corners respectively, so that the upper and lower corners of the edge are ground, and the chamfering of the two corners can be simultaneously performed.

In other words, it is possible to prevent the scorching caused by the grinding of the upper and lower vermiculite, or to improve the polishing efficiency and the grinding speed during polishing, and to remove the sludge adhering to the grinding portion, and to extract the use of the vermiculite. Limit, reduce the number of grindings, and avoid the water or sludge from scattering by the suction inside the cover to recover.

Then, by spraying the washing water and the air, the inconvenience caused by the contamination of the substrate surface is eliminated, and the washing water or the sewage sprayed and recovered by the suction in the cover body is absorbed by the suction force in the cover body, thereby avoiding the problem that the sewage is scattered to the outside. .

According to the above-described effects, it is possible to avoid the lack of judgment of defective products due to an inspection error such as debris in the inspection after the grinding (the camera interpretation) after scattering to the outside with the grinding. The reason for this is that there is no residual water droplets in the suction cap body, in other words, because two fluid nozzles and a capping body covering the upper and lower vermiculite are provided.

At this time, the mist of the mixed fluid generated by the grinding (grinding) and the glass frit mixed with the mist also flow from the opening to the lid, and are flushed by the mixed fluid of the washing water and the air, and suction is applied from the inside of the lid to the suction. When the mouth flows, the mist and the glass swarf inside the lid are recovered, which simplifies the inconvenience of adhering to the substrate surface on the outside of the opening due to scattering, that is, simplifies the work such as contamination or removal of the deposit after polishing.

Hereinafter, an embodiment of the present creation will be described based on the drawings. In the embodiment of the present invention, as shown in FIG. 1 to FIG. 4, the table A has an adsorption holding function, and a substrate such as a glass substrate or a ceramic plate is placed thereon.

As shown in FIG. 2, FIG. 3 and FIG. 4, the upper side vermiculite 3 and the lower side vermiculite 4 are polishing the annular protruding portions 5 for polishing the upper and lower corners of the upper and lower plates of the substrate a, and are engaged with each other (intrusion). And arranged in a zigzag shape (so-called parallel, as shown in FIG. 2 and FIG. 3, the upper side vermiculite 3 is provided with two protruding portions 5, and the lower side vermiculite 4 is provided with one protruding portion 5, but not limited thereto, When juxtaposed, the spacers 6 are interposed between the disc-shaped vermiculite forming the protruding portion 5 to form the aforementioned serration.

The upper side vermiculite 3 and the lower side vermiculite are mounted in the lid body 7 to be bearings, and the drive shaft 21 of the first motor 8 and the second motor 9 is connected to the center of the upper side vermiculite 3 and the lower side vermiculite 4, whereby the upper side vermiculite 3, the first motor 8 attached to the cover body 7 rotates in the counterclockwise direction in Fig. 1, and the lower side vermiculite 4 is rotated in the clockwise direction in Fig. 1 by the second motor 9 attached to the cover body 7.

The front edge of the table A of the cover 7 and its relative position are provided with an opening 10 that breaks into the polishing front edge of the substrate a, whereby the two protrusions 5 of the upper side vermiculite 3 and the lower side vermiculite 4 are inserted into the opening 10 The corners of the upper and lower plates of the edge are ground.

Further, a nozzle 11 and a lower nozzle 12 provided on the upper side of the lid body 7 are provided, and the outer periphery of the upper side vermiculite 3 and the lower side vermiculite 4, that is, the substrate polished (grinded) by the protruding portion 5, is opened from the opening 10. The upper side surface and the lower side surface of the edge of a are sprayed with a mixed pressure feed fluid to be described later.

The end side of the upper nozzle 11 and the lower nozzle 12 is provided with a storage portion 13 that is inserted into the hollow.

As shown in FIG. 1 and FIG. 5, the washing water from the first passage 14 that connects the two groups and the cooling water for polishing from the second passage 15 are individually supplied to the upper storage portion 13 and the lower storage portion 13, Thereby, the pressure air supplied from the air pressure inlet 16 in the middle of the first passage 14 and the second passage 15 speeds up the flow rate of the washing water and the polishing cooling water, and the outflow injection with the high speed is greatly reduced. The temperature rises due to washing or grinding; in addition to the significant improvement in washing efficiency and grinding (grinding) efficiency, the inflow (or recycling) of the lid body 7 can also be promoted.

In the inside of the lid body 7, the mist and the polishing powder accompanying the polishing are collected at the same time as the rinsing, and are recovered by a nozzle (not shown) that connects the suction port 20 at the bottom of the lid body 7, thereby avoiding the substrate a. A lot of inconvenience such as stains or glass shards remaining on the board surface. Of course, the upper side vermiculite 3 and the lower side vermiculite 4 may be washed by the fluid ejected from the upper nozzle 11 and the lower nozzle 12.

As shown in FIG. 5, the first passage 14 and the second passage 15 of the two sets of the above two groups have two protrusions 5 of the upper side vermiculite 3, so that the left and right two sets are juxtaposed, and the protrusions 5 of the lower side vermiculite 4 are only One set is provided, and each of the protrusions 5 is sufficiently washed with washing water or cooling cooling water, but not limited thereto, and the injection range of the upper nozzle 11 and the lower nozzle 12 can be used to achieve good results. Washing range.

Further, either the table A or the lid 7 is reciprocated in the right and left direction by the advancing and retracting movement mechanism B.

The moving mechanism B is arranged to move the table A as shown in the figure, but not limited thereto, the moving mechanism B can also be replaced with the support portion 22 under the cover 7 to move the cover 7 (Fig. Not shown).

The moving mechanism B is provided such that, as shown in the drawing, the rails 17 in the left-right direction are freely engaged with the slide rails 18 disposed under the casing 1, and the linear motors 19 are provided on the sliding surfaces of the rails 17 and the slide rails 18 To move forward and backward, but not limited to this, it can also be used for other forms of movement.

In this manner, the upper and lower corners of the substrate a can be simultaneously chamfered by moving the respective protruding portions 5 of the upper side vermiculite 3 and the lower side vermiculite 4 with the substrate a. As shown, the support portion 22 supports the cover body 7, and the lower side vermiculite 4 has a positioning swivel 23.

Further, as shown in FIG. 2, the discharge range (left-right direction) of the upper nozzle 11 and the lower nozzle 12 is larger than the parallel spacing of the side protrusions 5 which are engaged with each other, and this large range is used to achieve the upper and lower sides of the substrate A. The grinding (grinding) range is more widely sprayed.

According to the above configuration, the cooling water sprayed by the upper nozzle 11 and the lower nozzle 12 prevents the scorching of the upper vermiculite 3 and the lower vermiculite 4 during polishing (grinding), thereby improving the polishing effect. At the same time, it also achieved an increase in the grinding speed. Further, it has the effect of removing sludge adhering to the grinding portion, and the use limit of the vermiculite is accelerated, the number of times of grinding is reduced, and the water or sludge which is splashed outside is recovered under the suction force inside the lid body 7.

The washing of the first passage 14 and the spraying of the air wash the dirt on the surface of the substrate a, thereby avoiding the inconvenience caused by the dirt, and at the same time, under the suction inside the cover 7, the sewage is prevented from splashing outward (washing water) And it can be recycled for it.

Therefore, it is possible to avoid the erroneous determination of the defective product due to an inspection error such as debris in the inspection after the grinding (interpretation by the camera) after scattering to the outside. The main reason for this is that no water droplets remain under the suction force inside the lid body 7, and the two types of ejection fluid are sucked by the lid body 7 having the adsorption function. In this way, it can be carried out in conjunction with an inspection performed by a camera (omitted from the drawings).
