Description

{Adhesive Spreading Apparatus}

The present invention provides automotive vibration attenuating parts, in particular, an automobile which can improve the quality of a product by providing an application device capable of automatically applying and precisely applying an adhesive to the inner or outer surface of an anti-vibration bushing, And more particularly, to an automatic precision applying apparatus for vibration damping parts.

The vehicle continuously receives vibrations or shocks from the road surface through the wheels during driving, thereby providing a shock absorber between the vehicle body and the axle to prevent the shock and vibration from being directly transmitted to the vehicle body, thereby improving ride comfort and running stability.

The pivot portion of the suspension link mechanism is provided with a ball joint, a screw bushing, a rubber bushing, etc. In order to mitigate vibration and impact from the road surface and to secure stability and stability, Rubber bushings are widely used.

Since the anti-vibration bushing parts for automobiles are subjected to a large load depending on the application position, when there is adhesion failure between the metal pipe part and the rubber inside, damage and detachment often cause significant performance and safety problems.

For this reason, the process of applying the adhesive to the inner pipe of the rubber bushing is a very important process which determines the quality of the rubber bushing component.

However, in the conventional adhesive applying apparatus, it is possible to process a product having a simple shape, but it is difficult to apply the product to a product having a complicated shape, and in particular, it is impossible to apply the product on the inner surface.

As a result, the application process of products having a complicated shape at present is performed by the manual operation of the operator, and there is a problem that replacement of the JIG or PIN is required in accordance with the specification change of the product, and preparation time is long.

For this reason, application of a product having a complicated shape at present is remarkably lowered in productivity compared to other processes, and it is difficult to produce a stable product due to the degree of application depending on the skill of a worker, and it is difficult to spray at a constant speed. There is a problem in that defects are continuously generated.

Also, the adhesive sprayed by the turbulence phenomenon generated in the application booth scatters, thereby reducing the adhesion rate of the adhesive, and also exposing the worker to the dust generated during the process, which adversely affects the work environment.

In addition, in the case of conventional coating apparatuses, it is easy to incorporate flammable substances in the drying apparatus, thereby exposing the apparatus to the risk of fire. In the case of the actual adhesive application process, one or two fire accidents occur annually.

In addition, the hot-air drying apparatus, which is commonly used in the drying process, has a difficulty in maintaining a constant temperature, so that when the temperature control fails, the rate of occurrence of defects due to the flowing down of the adhesive is high and it is difficult to secure the reliability of the product. And it is in urgent need of improvement.

In addition, most current manufacturers of rubber bushing parts use manual spraying method to apply adhesives directly. Therefore, it is necessary to uniformly apply the adhesive to the inside of the cylindrical metal pipe due to non-uniform amount of adhesive application, unevenness of film thickness, There is a problem that a large number of defects occur.

In the adhesive application process, the worker bends his / her waist to apply heavy materials such as product and iron, and rotates to perform a coating operation. At this time, since the waist is bent and the worker manually rotates the table, the worker may cause musculoskeletal diseases , There is a problem that the worker tilts the body into the application booth in order to rotate the table, thereby exposing the human body to the spraying liquid, thereby causing a high possibility of causing skin diseases and respiratory disorders.

Accordingly, there is an urgent need to develop a coating apparatus capable of improving the above-described conventional problems, improving the working environment, and improving the quality and productivity of the product.
