Background Art

[0003] According to the shipbuilding industry, the three major domestic shipbuilders in Korea, such as Hyundai Heavy Industries, Samsung Heavy Industries, and Daewoo Shipbuilding & Marine Engineering, received a total order of $30.52 billion by last July. This is a level reaching about 86.9% of the $35.14 billion target value presented at the beginning of the year by the three shipbuilders.

[0004] According to the semi-annual reports submitted by the three shipbuilders this year, the total number of employees of the three shipbuilders at the end of last February was 36,594. Considering that the total number of employees of the three shipbuilders at the end of last year was 37,330, this is rather a decreased figure.

[0005] Major domestic shipbuilders in Korea plan to expand the introduction of robots in the shipbuilding process as an alternative to the shortage of manpower in the shipbuilding industry. Therefore, they plan to promote (such as collaborative welding robots) so that they can cooperate with workers. For the purpose of expanding the application to the site, they plan to concentrate on research and development of miniaturization / lightweighting of welding robots, and contribute to reducing the risk rate of safety accidents by the work of robots.

[0006] On the other hand, examining the current state of the aluminum industry in the shipbuilding sector reveals that the use of aluminum is expanding due to its lightweight and environmentally friendly effects. In the case of ships, steel has traditionally had a high specific gravity, but in the case of special vessels such as high-speed ships, LNG carriers, and leisure boats, aluminum sheets / profiles are used to manufacture and apply lightweight hulls and components.

[0007] While aluminum vessels offer the advantage of improved fuel efficiency and speed due to their lighter weight, they also have drawbacks such as high manufacturing costs and poor weldability. However, with the recent problems surrounding waste disposal of FRP vessels, there has been an increase in the construction of environmentally friendly vessels using aluminum.

[0008] However, in South Korea, there is no domestic production of high-strength aluminum plates for ships, so most of the aluminum plates used are imported. In order to build high-value-added vessels such as LNG carriers, high-speed ships, and leisure boats, which have seen an increase in construction volume recently, there is a need for domestic production of high-strength aluminum plates for ships.

[0009] In particular, in the case of aluminum windows for ships, ship windows are broadly classified into square windows and round windows, and the materials used are classified into steel and aluminum, which are the main materials used in shipbuilding, but the majority are manufactured using aluminum.

[0010] Although it varies depending on the size and type of vessel, a typical deckhouse on a large merchant ship has around 40 to 80 square windows. To meet the requirement for a certain level of structural strength even for square windows, each corner is bent into a rounded shape, requiring a single butt weld.

[0011] Recently, the sharp rise in international material prices, such as aluminum, has led to increased manufacturing costs. However, there are limitations to reflecting these costs in the order price of ships. Therefore, there is a need to develop automation technologies for simple, manual processes to ensure competitiveness in delivery prices.

[0012] In this regard, the manufacturing of aluminum square windows for ships requires more than 10 steps, and while some of the major processes have been automated, the welding process is still carried out entirely by hand.

[0013] This is because, unlike a simple rail-type welding method, the shape of the joint surface is diverse, and welding must be performed while rotating along the cross-section of the corner window. Therefore, implementing automation requires highly advanced technology and high development costs, and the related industries / companies are small and medium-sized enterprises with low sales volume and insufficient investment / response capabilities.

[0014] On the other hand, the key processes in the main manufacturing process of ship windows are "bending," "welding," and "finishing." These are the main manufacturing processes that prevent seawater from flowing into the hull due to adverse sea conditions, while the remaining main processes are simple processing and assembly processes.

[0015] Here, in the manufacturing process, a groundbreaking improvement in productivity and sales is expected when developing and applying dedicated automatic welding equipment in the "welding process."

[0016] In relation to automatic welding, Korean Patent No. 10-1153956 discloses a rail-driven automatic welding apparatus.

[0017] The aforementioned technology relates to a rail-running automatic welding apparatus, and more specifically, to a rail-running automatic welding apparatus comprising a fixed frame equipped with a control box that can travel along a rail and has a gear inside that is interlocked with a drive motor, a fixed guide portion provided at the lower part of the fixed frame and in close contact with the side surface of the rail, and a movable guide portion whose spacing with respect to the rail can be adjusted, wherein a slide bracket with a screw hole is provided on the movable guide portion side of the fixed frame to prevent the movable guide portion from detaching from the fixed frame, and one end of a screw shaft coupled to the screw hole is fixed to the movable guide portion to enable horizontal movement of the movable guide portion, and the spacing between the rail and the movable guide portion can be adjusted by rotating the screw shaft to fix it to the rail or move it away from it.

[0018] Furthermore, Korean Patent No. 10-2533753 discloses an automatic welding apparatus for round surfaces.

[0019] The aforementioned technology relates to an automatic round-surface welding apparatus that facilitates the fixing and alignment of tubular members and allows for easy removal of foreign matter remaining on the outer surface during welding of the inner surfaces between tubular members. This welding apparatus comprises a base portion 10 supported on the ground, a rotating portion 20 provided on one side of the base portion 10 for fixing and rotating the tubular members, a vertical moving portion 30 provided on the other side of the base portion 10 that is vertically movable, and a horizontal moving portion mounted on the vertical moving portion 30. The device includes a horizontally movable section 40, a welding section 50 provided at the end of the horizontally movable section 40 for welding with a welding wire, a tubular member support section 60 provided on the base section 10 between the rotating section 20 and the vertically movable section 30 for rotatably supporting the lower surface of the tubular member, a foreign matter combustion section 70 provided on the welding section 50 for burning off foreign matter on the rounded surface outside the tubular member, and a foreign matter removal section 80 provided on the welding section 50 for scraping out and removing the burnt foreign matter from the rounded surface outside the tubular member.

[0020] Although various technologies related to automatic welding have been disclosed, there is no technology that can perform automatic welding specialized for aluminum corner windows.

[0032] This invention relates to an automated production apparatus for aluminum square windows capable of automatic welding.

[0033] Specifically, this invention relates to an automated production system for aluminum square windows capable of automatic welding, which is configured to automatically weld aluminum square windows using a 360° turnover method, thereby ensuring purely domestic technological capabilities to automate the conventional manual welding process for aluminum square windows for ships.

[0039] Furthermore, the automatic aluminum square window production apparatus according to the present invention, which is capable of automatic welding, includes a table section and a welding section inside the frame section. The welding section is composed of an arm having multiple rotation axes, and by adopting a conventional arm structure in which one side of the welding section is rotatable, welding can be performed at multiple angles and in multiple directions, and such a welding section is driven by control from a control panel.

[0040] Furthermore, the table section serves to secure the aluminum square window and is capable of 360° rotation and lateral movement, enabling multi-directional welding of the aluminum square window.

[0041] Refer to Figure 2 in the attached drawings for an example of the aforementioned table section.

[0042] The table section shown in Figure 2 of the attached drawing includes a base made up of multiple frames, a work plate configured on the upper side of the base, a rail on the upper surface of the work plate, and a guide that moves along the rail.

[0043] Here, the guide may be an LM guide, but is not necessarily limited to it. The guide receives power via a power unit provided on one side of the work plate.

[0044] Furthermore, two of the aforementioned guides are provided on the work plate, and a fixing part for securing the aluminum square window is provided between the two guides. This fixing part is connected between the two guides, and the fixing part moves as the guides move. At this time, the aluminum square window fixed to the fixing part can move laterally.

[0045] Here, the fixing part only needs to be able to securely fasten the aluminum square window.

[0046] Furthermore, one side of the work plate is equipped with a rotating part that allows the aluminum square window to be rotated, and this rotating part will be explained with reference to Figures 3 to 5 of the attached drawings.

[0047] According to Figure 3 of the attached drawings, a base arm bent upward extends from one side of the lower surface of the work plate. One end of the base arm is connected to the lower surface of the work plate, and the other end is connected to the first arm. A second arm is connected to the other end of the first arm, a third arm is connected to the other end of the second arm, and a fourth arm is connected to the other end of the third arm. The other end of the fourth arm is provided with a projection.

[0048] Here, each arm coupling region from the base arm to the fourth arm is rotatably coupled, and a projection provided on the fourth arm is configured to contact a clamp (not shown) that connects the aluminum square window to the work plate.

[0049] Refer to Figure 5 in the attached drawing for the clamp.

[0050] The clamp includes a fixed body having a U-shaped cross-section so as to fit onto a work plate, the fixed body having a hollow interior, and the rotating shaft is connected via a hinge so as to be able to rotate.

[0051] The aforementioned rotating shaft has a block-shaped rotating body integrally formed on one side, and a pressing body is connected to the rotating body via a shaft.

[0056] On the other hand, the aforementioned fixing body is composed of an LM guide, and when the aluminum square window, which is fixed to the upper side of the work plate via a fixing part, is moved laterally along the guide, the fixing body can also move together with it.

[0057] Furthermore, since the aluminum square window is constructed to be hollow inside, when the aluminum square window rotates as shown in Figure 4 due to the rotation of the rotating body while the aluminum square window is fixed between the pressing body and the rotating body, the aluminum square window can pass through the first to fourth arms of the rotating part shown in Figure 3.

[0058] In other words, when the rotating shaft rotates due to the power transmitted to the hinge, the projection provided at the other end of the fourth arm assists the rotation by pressing against one side of the clamp as shown in Figure 4 of the attached drawing.

[0059] Thus, the automatic welding-capable automatic aluminum square window production apparatus according to the present invention has the advantage of securing purely domestic technological capabilities that enable the automatic execution of the conventional manual welding process for aluminum square windows for ships, by proposing an automatic welding apparatus with a structure specifically designed for aluminum square windows.

[0060] Furthermore, according to the present invention, by automating the conventional manual welding process, it is possible to reduce the number of man-hours required for the work, simplify the process, and reduce labor by preventing manual labor from being used for simple tasks, thus having the advantage of improving the productivity of companies.

[0061] The above description, based on the attached drawings, only discloses the main aspects of the present invention. Since a variety of designs are possible within its technical scope, it is clear that the present invention is not limited to the configuration shown in the drawings.
