BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of separating each cell from a drum during manufacturing a thin film glass product used for a display, an optical device and various accessories of an electronic product.

In general, a variety of electronic products such as smart phones, notebooks, and PDAs are equipped with a small-sized camera or a touch sensor to provide various functions. In order to protect the lens and the touch sensor of such a small camera, a very thin thin film glass is used.

In addition, thin-film glass is widely used as a component of various products in the optical field, and various accessories using thin-film glass are manufactured and sold.

Because these thin glass products are very thin, they are almost impossible to process on a sheet-by-piece basis because the thin glass is broken when a processing tool such as a cutter touches it.

When the thin film glass product is processed due to such a problem, a thin film glass ledge 10 having a large size is laminated to form the ledger laminate 20 as shown in Fig. 1, and the ledge laminate 20 is cut into a predetermined size 30), and then the drum 30 is used as a processing unit in various glass processing processes.

The laminate 20 is laminated by laminating the ledges 10 and applying the adhesive 11 between the ledge 10 and the ledge 10 and then curing the adhesive 11 so that the ledges 10 are stacked It is fixed.

The drum 30 is sliced to a predetermined size to form the drum 30 and the drum 30 is subjected to thin film processing such as healing and CNC processing and then processed from the drum 30 in the final stage The cell 31 is separated to complete the thin-film glass product.

A method of separating the cell 31 from the drum 30 is to immerse the processed drum 30 in lukewarm water to dissolve the adhesive 11 in water to separate each cell 31 from the drum 30 It takes a long time for the adhesive 11 to dissolve and when the cell 31 is detached from the drum 30, the gel-like adhesive 11 is often left on the surface of the cell 31, There is a time-consuming problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the accompanying drawings, wherein like reference numerals refer to like elements.

It is to be understood that when an element is referred to as being "comprising" another element in the description of the invention or in the claims, it is not to be construed as being limited to only that element, And the like.

As described above, since the thin glass is very thin, processing into a single sheet is very difficult. 1, a predetermined thin-film glass laminate 20 is formed by laminating a thin-film glass laminate 10 having a large size, and the cut laminated body 20 is cut with the cutter 40 20 are cut to a predetermined size to produce a hexahedron shaped book 30 as shown in FIG.

1, an adhesive 11 is applied between the ledge 10 and the ledge 10 to adhere and fix the ledge so that the ledged laminate 20 is stacked in the handling process of the ledged laminate 200, Fix the ledge (10) so that it does not move.

The adhesive (11) uses a template as a UV adhesive that hardens rapidly upon receiving ultraviolet rays.

1, the ultraviolet rays are irradiated to the laminate 20 to cure the adhesive 11 applied between the laminate 10 and the laminate 10, .

The drum 30 formed into a hexahedron shape as shown in FIG. 3 is processed into a thin film glass product through a process such as CNC machining, a groove is formed in the rim, or a hole in the form of a hole is machined.

In the final step, each of the cells 31 is separated from the drum 30 by the processed drum 30, which is a thin film glass product.

Conventionally, in order to separate the cells from the drum 30, the processed drum 30 is immersed in a tank filled with lukewarm water as shown in FIG. 8, thereby separating each of the cells 31 from the drum 30.

When the drum 30 is immersed in lukewarm hot water as described above, the adhesive agent 11 for dissolving the cells 31 is dissolved in the hot water to separate the cells 31. The adhesive agent 11 is completely dissolved in the hot water it takes a lot of time.

When the worker removes the cell 31 from the drum 30 before the adhesive 11 is completely dissolved, the adhesive 11 in the gel state appears on the surface of the cell 31, Since the burnt adhesive 11 must be wiped off, the production efficiency is greatly reduced.

The present invention irradiates ultraviolet rays to the machined drum 30 with the ultraviolet lamp 50 as shown in Fig. 5 before immersing the machined drum 30 in the hot water, The adhesive 11 to which adhesive is fixed is completely cured.

At this time, as shown in Fig. 6, the length between the faces opposed to each other in the hexahedron shaped drum 30 is set so that the ultraviolet rays are radiated from the four directions to the drum 30 in the planar direction, and from 3,750 to 6,250 mJ in each direction It is preferable to irradiate the drum 30 with ultraviolet rays in a total amount of 15,000 mJ to 25,000 mJ.

When the ultraviolet rays are irradiated in the four directions as described above, the adhesive 11 is uniformly cured, rather than irradiating ultraviolet rays in one direction.

If the ultraviolet total irradiation amount is less than 15,000 mJ in a thin glass having a thickness of 0.3 mm or less depending on the thickness of the thin film glass, the adhesive 11 is not cured properly and the interface between the adhesive 11 and the cell 31 is activated If the ultraviolet total irradiation amount exceeds 25,000 mJ, it is preferable to irradiate the ultraviolet total irradiation amount of 15,000 mJ to 25,000 mJ since the cell 31 is deteriorated by heat.

6, the adhesive 11 for adhering and fixing the respective cells 31 of the drum 30 is completely cured and ultraviolet rays are irradiated to the processed drum 30 to form the cells 31 of the drum 30 And the adhesive 11 is activated.

That is, the adhesive 11 is completely cured by ultraviolet irradiation, and the interface between the cell 31 and the adhesive 11 is activated to form a fine gap between the cell 31 and the adhesive 11 as shown in FIG.

The drum 30, in which the interface between the cell 31 and the adhesive 11 is activated by ultraviolet irradiation as described above, is immersed in a lukewarm hot water tank as shown in FIG.

Hot water flows into the fine gap between the cell 31 and the adhesive 11 and the adhesive 11 flows into the gap between the cell 31 and the adhesive 11 by immersing the drum 30 in which the interface between the cell 31 and the adhesive 11 is activated in the warm water tank. The cells 31 are separated from the drum 30 with fast dissolving.

The present invention constructed as described above can quickly separate the cell 31 from the drum 30 and can cleanly separate the cell 31 so that the adhesive 11 does not remain on the surface of the cell 31 at the time of separation. Therefore, the production time of the thin film glass product can be remarkably shortened.

The technical idea of the present invention has been described above with reference to the embodiments.

It will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described above from the description of the present invention.

Further, although not explicitly shown or described, those skilled in the art can make various modifications including the technical idea of the present invention from the description of the present invention Which is still within the scope of the present invention.

The above-described embodiments described with reference to the accompanying drawings are intended to illustrate the present invention and the scope of the present invention is not limited to these embodiments.
