Abstract

PURPOSE:To keep constant the distance between very small parts and the tips of needles, not to feel the needles with your fingers when handling and to prevent the damage, deformation, etc., of the needles by vertically and downward installing a ring-shaped projecting part a little higher than the needles outside the needles. CONSTITUTION:Plural needles 3 are arranged vertically downward in the central part of a bottom plate 2 of a nozzle body 1, and a ring-shaped projecting part 6 0.1-0.5mm higher than the needles 3 is vertically downward in the outside of the needles 3. In a multinozzle of such a construction, when used, by abutting the ring-shaped projecting part 6 on very small parts, the distance between the very small parts and the ring-shaped projecting part 6 is kept constant to prevent the damage of the tips of the needles 3. And since the needles 3 are completely surrounded by the ring-shaped projected part 6, you do not feel the needles 3 with your fingers when handling the multinozzle, and even when it is left on a work bench in disorder, the thin needle 3 are prevented from being bent or their tips from being crushed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a multi-nozzle for spraying an adhesive, spraying a coating material, or spraying a gas or a solvent on a minute component.

[0002]

2. Description of the Related Art In one of the conventional multi-nozzles for the above-mentioned use, a plurality of needles 3 are arranged vertically downward at a central portion of a bottom plate 2 of a nozzle body 1 as shown in FIG. There is one in which a guide rod 4 longer than the needle 3 is arranged vertically below. By the way, in the multi-nozzle 5 having such a structure, the guide rod 4 keeps a constant distance between the minute component and the tip of the needle 3 during use to prevent the needle 3 from being damaged, but the circumference of the needle 3 is completely surrounded. Therefore, the thin needle 3 may be bent or the tip may be crushed by a finger touching the gap of the guide rod 4 during handling. The same thing occurs when the multi-nozzle 5 is left undisturbed on the work table.

[0003]

Therefore, the present invention can keep the distance between the minute component and the tip of the needle constant during use, prevent the finger from touching the needle during handling, and clutter the workbench. It is intended to provide a multi-nozzle which prevents the needle from hitting the needle even when left unattended.

[0004]

The multi-nozzle of the present invention for solving the above-mentioned problems is a multi-nozzle in which a plurality of needles are arranged vertically downward in the central portion of the nozzle body, and It is characterized in that a ring-shaped convex portion slightly higher than the needle is provided vertically below.

[0005]

As described above, in the multi-nozzle of the present invention, a ring-shaped convex portion slightly higher than the needle is provided on the outside of the needle in the vertically downward direction. By contacting each other, the distance between the minute component and the tip of the needle is kept constant, and the needle is prevented from being damaged. In addition, since the circumference of the needle is completely surrounded by the ring-shaped convex portion, the needle does not touch the finger during handling, and the needle does not hit even when left undisturbed on the workbench, so a thin needle Does not bend or crush the tip. Further, when the adhesive or the coating material is discharged and applied, the application surface of the minute component is surrounded by the ring-shaped convex portion, so that the adhesive or the coating material does not flow to the outside, and the application amount becomes constant and uniform. Can be applied to thickness.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the multi-nozzle of the present invention will be described with reference to FIG. 1. A plurality of needles 3 are vertically arranged at the center of a bottom plate 2 of a nozzle body 1, and the needles 3 are provided outside the needles 3. 0.1 mm to 0.5 mm higher than the ring-shaped protrusion 6
Is provided vertically below. According to the multi-nozzle 5'having such a structure, the ring-shaped convex portion 6 is brought into contact with the minute component during use, so that the distance between the minute component and the tip of the needle 3 is kept constant and damage to the needle 3 is prevented. It
Further, since the circumference of the needle 3 is completely surrounded by the ring-shaped convex portion 6, the finger 3 does not touch the finger during handling, and the needle 3 does not hit even when left undisturbed on the workbench, Therefore, the thin needle 3 is not bent or the tip is not crushed. Furthermore, when the adhesive or the coating material is discharged and applied, the application surface of the minute component is surrounded by the ring-shaped convex portion 6, so that the adhesive or the coating material does not flow to the outside, and the application amount becomes constant and uniform. It can be applied in various thicknesses.

[0007]

As described above, according to the multi-nozzle of the present invention, the distance between the minute parts and the tip of the needle can be kept constant during use, the finger does not touch the needle during handling, and the work table is cluttered. Since the needle does not hit even if left unattended, it is possible to prevent damage, deformation, crushing of the tip, etc. of the needle. Further, since the adhesive and the coating material applied to the minute parts are not leaked to the outside, the application amount is constant and the application is performed with a uniform thickness.
