Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin glass plate, and more particularly to a processing method and a processing device for notching a glass plate having a thickness of 2 mm or less, and a blood test glass case used in an electrophoresis method.

[0002]

2. Description of the Related Art Conventionally, for example, a thin glass is used for a blood test glass case used in an electrophoresis method, and the following cases are used when the thickness is about 3 mm or less than 2 mm. It used different processing methods.
As shown in FIG. 5, when a cutout is formed in a plate glass having a thickness of 3 mm, holes A and B are formed at the cutout positions with a core drill.
Then, cuts C and D are made with a rotary blade, and then a line F connecting the holes A and B is made with a glass cutter, and then a fold is made. It is possible to use the core drill in this way because the glass has a sufficient thickness.

If the thickness is 2 mm or less, since the thickness is too thin and the glass is broken when the core drill is used, as shown in FIG. A method of cutting to a predetermined position with a wheel blade or a grindstone having a width corresponding to the width is adopted.

[0004]

When the core drill shown in FIG. 5 is used, the opening portion of the core drill remains arcuate, which is not preferable as a blood test glass case in which a sharp notch is desired. There's a problem.
In addition, there is also a drawback that a process using a core drill is required, which increases processing cost.

Further, when the perforation method using the thick blade shown in FIG. 6 is adopted, it is possible to process a plurality of glass plates at a time, but since a cutting step of sequentially scraping is required, it takes time and cutting. As the processing progresses, the edge R of the blade becomes worn and rounded, and as a result, the cutout corner portion is rounded as in the case of FIG. 5, which is not preferable as a blood test glass case.

In view of the above problems, the present invention is capable of processing thin glass, particularly those having a thickness of 2 mm or less, in a short time and while the cut surface can be processed neatly, and the cutout corners are always at right angles. An object of the present invention is to provide a method and apparatus for processing thin glass that can be formed, and a glass case for blood test used in an electrophoresis method.

[0007]

The thin glass processing method according to the present invention has a thickness of 2 to achieve the above object.
A method for notching thin glass of not more than mm, in which at least one cut is made at a predetermined position from the side edge of the thin glass with a disk-shaped blade, and the cut end and the side edge or cut end of the thin glass A measure was taken to tie the lines and draw a line with a glass cutter, and then to fold the part surrounded by the cut and the line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the processing method of the present invention, a thin plate, in particular, one which cannot be perforated by a core drill having a thickness of 2 mm or less is cut with a thin disk-shaped blade, and a score line with a glass cutter is used. By doing so, it is possible to easily fold it, and compared with the above-mentioned conventional technology, this makes it possible to make the cut surface clean, while keeping the cutout corners always at right angles and greatly shortening the processing time. .

Further, in the present invention, if the disc type blade is a diamond blade or a grindstone having a thickness of 0.2 to 0.5 mm, it is possible to perform a clean cutting without causing cracking when cutting into thin glass sheets. .

According to the device of the present invention, the thickness is 2 m.
The notch in the notch processing of the thin glass sheet having a size of m or less can be easily regulated by the operation position regulating tool by manually feeding the placing table to make the notch to the predetermined position.

Further, in the present invention, when the cylinder driving means for driving the mounting table is provided,
The above table can be fed automatically,
Work can be done efficiently.

Further, according to the glass case for blood test used in the electrophoretic method of the present invention, since the thin glass processed by the above-mentioned processing method is used, the cut surface is clean and the cutout corner is formed. Can always be formed at a right angle, which is very useful as a case of this kind, and the processing cost can be reduced, so that it can be provided at a low cost.
