能率的であつた。 Conventionally, as a method for applying a fixed amount of adhesive, a syringe-like liquid dispensing device (dispenser) is used, and the adhesive is dropped onto the coating surface of the glass substrate 1 from the tip of the needle of the dispenser. However, with this method, the adhesive does not rise sufficiently on the coated surface, so it is necessary to spread the dropped adhesive onto the coated surface with the tip of a needle, and the width of the stretched adhesive It has the disadvantage of poor accuracy. As described above, conventional adhesive quantitative application methods are mostly manual and inefficient.

る。 Hereinafter, the present invention will be explained with reference to illustrated embodiments.
FIG. 2 shows an embodiment of the coating method according to the present invention, in which a is a side view, b is a front view, and FIG. 3 is a plan view of the scratching jig. As shown in the figure, a plurality of substrate storage grooves 3a are formed in the substrate holder 3 that holds the glass substrate 1 so as to vertically store the glass substrate 1 forming the liquid crystal display element container. A receiving portion 3b for receiving the glass substrate 1 is formed at the lower end of the groove 3a. A rotary disk 4 for applying adhesive to the glass substrate 1 is provided to rotate in the direction of arrow A, and its lower part is immersed in adhesive 6 in an adhesive tank 5. A groove 4a is provided on the outer periphery of the rotating disk 4, and in order to apply a fixed amount of the adhesive 6 carried by the groove 4a to the glass substrate 1, no unnecessary material is provided on the outer periphery of the rotating disk 4. A scraping jig 7 for scraping off the adhesive is lightly pressed.

布される。 Therefore, the substrate holder 3 is set at a constant height so that the lower end of the glass substrate 1 contacts the upper surface of the rotating disk 4, and the rotating disk 4 is rotated in the direction of arrow A. Move in direction B. When the rotating disk 4 rotates, the adhesive 6 in the adhesive tank 5 adheres to the groove 4a and the outer periphery of the rotating disk 4, and moves upward as the rotating disk 4 rotates. Then, the excess adhesive is scraped off by a scraping jig 7 and collected into the adhesive tank 5. The adhesive remaining in the groove 4a after being adjusted to a certain amount is transferred to the rotating disk 4.
A fixed amount is applied by contacting the glass substrate 1 set on top of the glass substrate 1. In this case, the substrate holder 3 is also
Since the glass substrates 1 are moved in the same direction, a fixed amount of adhesive is continuously applied to the plurality of glass substrates 1 in the substrate holder 3 one after another.

の接着剤の盛り上りを防止できる。 Here, the amount of adhesive that rises from the groove 4a can be adjusted by providing a depression in the scratching jig 7 or making it flat. Furthermore, if the circumferential speed of the rotating disk 4 and the moving speed of the substrate holder 3 and the rotational direction of the rotating disk 4 and the rotational direction of the substrate holder 3 are made the same, the adhesive can be applied to both sides of the glass substrate 1. It can prevent climbing.

状であつても適用できる。 In the above embodiment, the groove portion 4a is provided on the outer periphery of the rotating disk 4, but a cloth or the like is wrapped around the outer periphery of the rotating disk 4 as a quantitative adhesion means, and the adhesive impregnated in this cloth is applied to the glass substrate 1. It may also be applied by coating. Alternatively, the substrate holder 3 may be fixed and the rotating disk 4 may be moved in the direction of arrow C. Further, in the above embodiment, the case where the coating is applied to the end surface of the glass substrate has been described, but the coating can be applied even if the coating surface of the object to be coated is flat or curved.

定量の接着剤を高精度に塗布することができる。 As is clear from the above explanation, according to the method for quantitatively applying adhesive according to the present invention, the object to be coated is brought into contact with the adhesive adhered to the groove provided on the outer periphery of the rotating disk or to the quantitatively applying means. Since the rotating disk is rotated and the rotating disk and the object to be coated are moved relative to each other for coating, it is possible to automatically and continuously apply a fixed amount of adhesive in a constant width with high precision.
