Description

[0001] The present invention relates to a joining material drawing nozzle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bonded material draw-out nozzle for supplying an encapsulating material silicone, a sealant or the like, which is used for achieving sealing bonding between panel-to-panel bonding parts such as automobiles or structures having different surface structures.

The present invention relates to a method and apparatus for automatically sealing a sealing material, such as a silicone or a sealant, by an application robot in order to seal and adhere bonding structures between panels or structures having different surface structures, And is fixed by adhesion.

The materials serve not only to bond the sheet metal parts in a sticky manner, but also to function as a temperature blocking agent and a sealant as noise, waterproof or heat insulating materials.

Unlike the embodiment in a large factory, the sealing material has a nozzle (repair or application nozzle) through which a material is drawn and can be quickly supplied to the joint by a robot supplied with a large amount of material. There is a problem that an expensive robot can not be purchased in a small-scale car-center or a maintenance factory for restoring and repairing an accident after an accident occurred.

A repair or application nozzle is detachably attached to the container by a screw connection so as to eject the viscous material with the container containing the viscous material of the present invention, Unlike a robot that uses air pressure in a large factory, which consists of a piston and a piston, the small-sized car repair shop is used as a hand-operated gun and an air-type gun.

When the material is jetted out, the mechanical robot can generate a high extrusion pressure and can continuously supply the uniform pressure, but it can not perform the uniform operation due to the manual operation.

In other words, the ejection of the material through the nozzle can not achieve uniform ejection when the forces and pressures are applied uniformly, and the problem of deterioration of the surrounding pollution and sealing function,

The material ejected by these nozzles may be distributed over a wide area enclosing the entire horizontal joint, or may be coated with appropriate thickness and width in the corners and gaps, and may be blocked by adhesive bonding, noise or temperature effects, In order to increase the role, the drawn material is in the form of continuous wrinkles in the form of "ssss" shaped wrinkles.

In order to accomplish the above object, the prior art Korean Patent Laid-Open Publication No. 10-2011-0128912 describes a nozzle for forming a continuous wrinkle shape. However, the description is based on a combination of a container and a nozzle, And an elongated discharge hole is formed in the curved end portion so that the material to be jetted is drawn out in a wide area and the drawing speed is controlled to form the continuous wrinkle shape described above.

This prior art is not applied to a pullout robot or improves the aforementioned drawbacks in manual work.

As another prior art, a conventional utility model registration No. 20-0409723 which is not a continuous wrinkle shape has a triangular configuration in which the nozzle is sharpened at the tip of a junction part, and the utility model registration No. 20-0435113 A cutting means for cutting a sharp end to a required size, and a guide for guiding the exit.

In addition, the No. 10-0638276 discloses a configuration in which a nozzle having a sharp end is bended so that the nozzle can be brought into close contact with the abutment portion, and a guide piece is closely attached to the adhesion portion at the lower end of the nozzle, , This configuration can not provide a continuous wrinkle shape of the above-mentioned new type.

As described above, the prior art is limited to the nozzle which can be cut according to the size of the guide piece and the draw-out hole for the close contact with the joint and the guide for the conveyance, so that when the pressure is unbalanced, It can not supply the desired thickness and amount because it can not be discharged, and the amount according to the extrusion pressure is poor, so that the disadvantage that the applied surface is thick, thin, or spouted around is not improved at all.

And, Registration Practical Utility Model No. 20-0330865 constitutes anti-bubble generation part in the silicone application cap to attenuate the bubbles flowing from the outside, so that uniform and uniform silicone application work can be performed. However, as described above, merely the shape of the embossing on the nozzle is merely to attenuate the bubbles flowing in from the outside, and there is a disadvantage in that the flow rate of the silicon can not be controlled evenly by the pressure change, and Patent Document 10-2011-0035299 Since the entire length of the nozzle is not extended due to the multi-stage nozzle, the pulling pressure applied when the worker pulls the sealant is not high, so it can be easily pulled when pulling the sealant gun. However, No. 20-2014-0003847 discloses a method of manufacturing a nozzle having a silicone outlet formed in a container and an elongated member extending from the nozzle to form an elongated nozzle so as to facilitate nozzle access to a narrow space, It is possible to form the continuous wrinkle-like material of the present invention There is no clear purpose structure.
