Description

An apparatus for cleaning coupling

The present invention relates to a coupling cleaning device, and more particularly, by automatically proceeding the entire cleaning process, the cleaning process can be reduced and the cleaning time can be reduced, and alkaline ionized water can be used as the cleaning water. It relates to a coupling cleaning device capable of preventing contamination.

In general, machinery and equipment used in various industrial sites and industrial products such as automobiles and ships are manufactured using various parts.

Among them, parts such as heavy gears and couplings are indispensably mounted on heavy-duty industrial products such as automobiles and ships. As described above, before mounting the parts, foreign substances on the surface of the parts are removed and rust is prevented. Washing and rust prevention work is performed so as to do so.

1 is a flow chart schematically showing the cleaning and rust prevention work process of a conventional gear part, and the work is largely performed through washing, drying, rust prevention, and drying processes, and most of the work is performed depending on manual work.

In other words, in the general manual process, the cleaning process removes foreign substances on the surface of gear parts through spraying of cleaning liquid by the worker's spray gun on a cleaning workbench equipped with a drainage facility.

In addition, after the above-described cleaning process, the cleaning liquid on the surface of the part is removed with a spray air gun to dry the cleaning liquid and dried naturally, thereby completing the cleaning operation of the part surface.

After completion of the cleaning process, in the rust prevention process, the rust prevention liquid to be coated is placed in a bathtub, and the cleaned gear parts are immersed in the bathtub for a certain period of time, and then dried naturally, thereby completing the rust prevention work on the surface of the parts.

In this way, after the parts are cleaned and rust prevented, the parts manufacturing process is completed through product inspection and packaging processes.

However, in the conventional parts cleaning and rust prevention work as described above, due to the nature of work performed by hand, the operator must directly transfer heavy parts and perform cleaning and rust prevention work.

Therefore, there is a disadvantage in which industrial accidents such as musculoskeletal disorders such as waist, knee, and shoulder frequently occur due to repetitive transportation work in the process of washing parts and preventing rust.

Moreover, as described above, since the part rust prevention process is largely carried out by hand, the rust prevention liquid of an organic solvent component with high volatility in the rust prevention process scatters into the atmosphere and is absorbed into the human body by the worker's breath, which affects the central nervous system. There were also bad things that caused fatal problems in the human body, such as causing neurological disorders.

In addition, due to the nature of manual cleaning and rust prevention work, it is impossible to continue working without a break, so there was a problem that it was difficult to ensure uniform product quality as well as poor product production efficiency, and sufficient manpower due to the arduous work environment Not only was it difficult to secure, but there was also a problem that caused the company's profitability to deteriorate due to significant labor expenses.
