Abstract
Description
Technical Field
[0001] The present invention relates to an automatic buffing device for marine aluminum corner windows. More specifically, in the manufacturing process of marine aluminum windows, it relates to an automatic buffing device for marine aluminum corner windows that utilizes a vertical multi-joint robot arm to execute the buffing process, which influences the product quality competitiveness. In this device, in order to eliminate incomplete polishing caused by errors in the bending and welding processes of the automatic buffing machine, the existing 360-degree rotating turntable method is excluded, and the precision and effectiveness of the buffing process are maximized by manufacturing an automatic buffing machine using a vertical multi-joint robot arm.
[0002] According to such a present invention, it does not require a high level of technical ability in the manufacturing of aluminum corner windows. In the buffing process where the working conditions are not good due to dust and it is most difficult to employ manpower, by arranging a dust suction inlet near the grinding machine to suck dust, it is expected to greatly contribute to improving the working environment, constructing process automation, reducing costs, and improving productivity.
Background Art
[0003] An aluminum corner window cover means a manufactured product for finishing an aluminum window as shown in FIG. 1.
[0004] Such an aluminum corner window cover usually has a horizontal length of 400 - 600 cm, a vertical length of 300 - 450 cm, and a thickness of 0.5 - 0.7 cm. The material is aluminum, which is advantageous for processing and deformation.
[0005] Such an aluminum corner window cover is obtained by banding an aluminum flat plate, performing aluminum welding work, then straightening work, then hole processing, and after an anodic oxidation treatment film work, it is installed on an aluminum window frame.
[0006] However, when processing the entire surface and sides of an aluminum square window cover by hand using a sanding machine, the worker has to adjust the force they apply, which results in an uneven surface finish depending on the individual's strength and skill. Furthermore, as shown in Figure 2, processing by hand can cause the aluminum square window cover to deform.
[0007] Furthermore, the high-speed rotation of the sandpaper grinding machine poses a safety risk to the workers.
[0008] In other words, during the processing of aluminum square windows, the polishing work is performed manually by the workers, which can lead to problems such as uneven surface finishes depending on the skill level of the workers, or the need to redo the polishing of the aluminum square windows due to poor workmanship. Furthermore, the high rotation speed of the buffing machine can threaten worker safety and become a factor in causing industrial accidents.
[0009] Furthermore, the manual nature of the buffing process makes it difficult to achieve product quality standardization and increased production volume, highlighting the need for solutions to overcome these challenges.
[0010] Therefore, we aim to develop a robotic automatic buffing machine specifically for aluminum square windows that can perform a buffing process using a vertical articulated robotic arm after banding and welding the chassis, which is the core material of the aluminum square window, and then performing automatic clamping according to specifications.

[Modes for carrying out the invention]
[0025] Terms and words used in this specification and in the claims should not be construed to be limited to their ordinary or dictionary meanings, but rather to be interpreted in a way that is consistent with the technical idea of the present invention, in accordance with the principle that inventors may appropriately define the concepts of terms in order to best describe their invention.
[0026] Therefore, the embodiments and configurations shown in the drawings disclosed herein are merely preferred embodiments of the present invention and do not represent the entire technical concept of the present invention. It should be understood that there are various equivalents and modifications that can be substituted therewith at the time of filing.
[0027] Before describing the present invention with reference to the drawings, it should be made clear that matters not necessary to illustrate the gist of the present invention, i.e., known configurations that can be obviously added by a person skilled in the art, are not shown or specifically described.
[0028] This invention relates to an automatic buffing device for aluminum rectangular windows used in ships.
[0029] Specifically, the present invention relates to an automatic buffing device for aluminum rectangular windows for ships, which utilizes a vertical articulated robot arm to perform the buffing process, a process that significantly impacts the quality competitiveness of the product in the manufacturing process of aluminum windows for ships. In order to eliminate incomplete polishing caused by errors in the bending and welding processes of the automatic buffing machine, the present invention eliminates the existing 360-degree rotating turntable system and maximizes the precision and effectiveness of the buffing process by manufacturing an automatic buffing machine that utilizes a vertical articulated robot arm.
[0030] According to this invention, the production of aluminum square windows does not require advanced technical skills, and in the buffing process, where dust makes working conditions good but manual labor is most difficult, the dust intake port is placed close to the polishing machine to suck up the dust. This is expected to improve the working environment and enable process automation, thereby contributing significantly not only to cost reduction but also to increased productivity.
[0031] The automatic buffing device for aluminum rectangular windows for ships according to the present invention will be described below with reference to the attached drawings.
[0032] Figure 3 shows an automatic buffing device for aluminum square windows for ships according to the present invention, Figure 4 is a magnified view of the lower end of the automatic buffing device for aluminum square windows for ships shown in Figure 3, and Figure 5 is a magnified view of the upper end of the automatic buffing device for aluminum square windows for ships shown in Figure 3.
[0033] Here, Figure 6 shows a polishing machine configured at one end of the robot arm of the automatic buffing device for aluminum square windows for ships according to the present invention.
[0034] Figure 7 shows the table of the automatic buffing device for aluminum rectangular windows for ships according to the present invention.
[0035] Here, Figure 9 is a magnified view of the fixing area of the rectangular window in the table of Figure 7, and Figure 9 is a diagram showing the configuration of the cylinder fixing device for fixing the rectangular window in the table of the automatic buffing device for aluminum rectangular windows for ships according to the present invention.
[0036] First, referring to Figure 1 of the attached drawings, the automatic buffing device for aluminum rectangular windows for ships according to the present invention (hereinafter referred to as "buffing device 10") includes a robot arm 11 and a table 12.
[0037] The robot arm 11 is a multi-jointed, driven arm-type robot, and a polishing machine 119 for the buffing process is attached to its end. The polishing machine 119 is not shown in Figure 3, but is illustrated in Figure 6.
[0038] A table 12 is configured adjacent to one side of the robot arm 11, and an aluminum square window 124 is mounted and fixed to the table 12. Once the square window 124 is fixed to the upper surface of the table 12, the square window 124 is buffed by a polishing machine 119. For this purpose, the robot arm 11 is configured with multiple joints and driven along the upper surface of the table 12.
[0039] The robot arm 11 will be described below with reference to Figures 4, 5, and 6 of the attached drawings.
[0040] The robot arm 11 includes, with respect to the base 111, a body 112 configured on the upper surface of the base 111 and equipped with a motor inside, a rotating body 113 connected to the upper side of the body 112 and connected to the motor of the body 112 and receiving rotational force, a support body 114 connected to the upper side of the rotating body 113 and rotating by the rotational force of the rotating body 113, a first arm 115 connected to a motor that receives power (electric, air, or hydraulic, etc.) and rotates on one side of the support body 114 and rotates from the support body 114 at a predetermined angle with the motor as the reference axis, and a cylindrical auxiliary arm 116 whose ends are connected via hinges from the other side of the support body 114 to one side of the first arm 115.
[0041] In other words, when the first arm 115 rotates around a reference shaft, which is the lower end connected to the support 114, by the power of the motor, the rotation of the first arm 115 is assisted by adjusting the extension length of the auxiliary arm 116, which is composed of a cylinder.
[0042] Here, the rotating body 113 can be easily designed by an ordinary engineer, but as explained with reference to Figure 4 of the attached drawings, it is sufficient to include a base configuration that is coupled to the upper surface of the fuselage 112 and a rotating configuration that contacts the base configuration and is coupled to the motor shaft to rotate.
[0043] Furthermore, although the hydraulic coupling structure for driving the configuration of each arm is not described in detail in this invention, an ordinary engineer should be able to easily apply a hydraulic line coupling structure.
[0044] In other words, the main feature of the present invention is a multi-joint robot arm having an arm structure, which can approach a table by the rotation or rotational drive of each joint. The hydraulic coupling structure for driving the robot arm is obvious to the average engineer and will not be described in further detail.
[0045] Referring to Figure 5, a coupling body 117 is attached to the other end of the first arm 115 using a motor that rotates with a separate power source. The coupling body 117 can rotate from the first arm 115 to a predetermined angle with respect to the shaft of the motor provided at the other end of the first arm 115.
[0046] A second arm 118 extends from one side of the aforementioned coupling 117. The second arm 118 is configured to be coupled to the shaft of a motor provided on the other side of the coupling 117, so that the second arm 118 can rotate in a 360° direction by the rotation of the motor on the coupling 117.
[0047] Furthermore, a front end rotating arm 118a is provided at one end of the second arm 118, which is connected by a motor, and the front end rotating arm 118a can be rotated to a predetermined angle by the rotation of the motor.
[0048] A polishing machine 119 is vertically coupled to the end of this front rotating arm 118a.
[0049] With a robot arm 11 having such a configuration, it can rotate in all directions by the rotating body 113, the first arm 115 can rotate to a predetermined angle in the front-rear direction, the second arm 118 can rotate to a predetermined angle vertically from the first arm 115, the second arm 118 can rotate around its axis by the motor of the connecting body 117, and the front end rotating arm 118a can also rotate to a predetermined angle, thus having the advantage of being able to accommodate multiple joint directions on the upper surface of the table 12.
[0050] The aforementioned table 12 will be explained based on Figures 7 to 9 of the attached drawings.
[0051] The table 12 comprises a table body 121 configured at a predetermined height from the ground, a transport means 122 coupled to the underside of the upper surface of the table body 121, one or more cylinder fixing devices 123 configured on one side of a transport plate 1223 configured on one side of the upper surface of the table body 121, and a corner window 124 fixed by the cylinder fixing devices 123.
[0052] Here, the transfer means 122 functions to allow the transfer plate 1223 to be transferred in a predetermined direction on the upper surface of the table body 121, and may include a predetermined conveyor belt, but as shown in Figure 4 of the attached drawings, it is configured in a cylindrical shape on one side of the table body 121, the rod of the cylinder is the transfer body 1221, a guide body 1222 is connected vertically upward to one side of the transfer body 1221, and the transfer plate 1223 is connected to the guide body 1222.
[0053] Here, for the configuration of the guide body 1222, one side of the upper surface of the table body 121 may include a guide hole (not shown) through which the guide body 1222 can move.
[0054] In other words, although Figure 7 shows two transfer plates 1223, this figure represents the state in which the transfer plates 1223 have moved.
[0055] Furthermore, the reason why the cylinder fixing device 123 consists of one or more units is to fix the rectangular corner window 124 in at least two directions on the upper surface of a single transfer plate 1223.
[0056] Such a cylinder fixing device 123 includes a rod 1231, and the end of the rod 1231 includes a corner window fixing portion 1232, thereby providing a lateral fitting hole ( A rectangular window 124 having an end of the shape of JPEG0007864153000002.jpg99 is supported at the lower end of the protruding region.
[0057] On the other hand, although not indicated by a drawing reference numeral, auxiliary supports having the same height as or lower than the corner window fixing portion 1232 can be configured perpendicular to the corner window fixing portion 1232 in both directions. Such auxiliary supports are provided to ensure support force for fixing the corner window 124 even when pressed from above during the buffing process using the polishing machine 119.
[0058] Such a cylinder fixing device 123 will be described based on Figure 9 of the attached drawings.
[0059] As shown in the uppermost diagram of Figure 9, the cylinder fixing device 123 includes a U-shaped holder 12311 having a "U" shape and provided at the end of the rod 1231 of the cylinder fixing device 123, a rotating part 12313 whose end is located inside the hollow of the U-shaped holder 12311 and is connected via a hinge 12312, and an extension body 12314 connected to the end of the rotating part 12313, with a corner window fixing part 1232 vertically connected to the end of the extension body 12314.
[0060] On the other hand, as another example, as shown at the lower end of Figure 8, the corner window fixing portion 1232 may have two auxiliary rotating portions 12321 configured symmetrically in one direction, in addition to the plate portion.
[0061] As a result, a hollow 12322 is formed between the two auxiliary rotating parts 12321, and the other end of the extension 12313 is inserted into the hollow 12322 and connected via a hinge.
[0062] Here, the hinge connecting the extension and the auxiliary rotating part may further include a torsion spring.
[0063] Furthermore, by connecting a motor and gears to one side of the hinge 12312 that connects the rotating part 12313 and the U-shaped holder 12311, the rotating part 12313 and the extension body 12314 can be raised or lowered relative to the cylinder fixing device 123. When the extension body 12314 is raised in this manner, the corner window fixing part 1232 can rotate slightly to support the corner window 124 in a vertical direction, thus usefully addressing situations where some height adjustment of the corner window 124 is necessary.
[0064] As described above, the present invention provides an automatic buffing device for aluminum square windows for ships, which utilizes a vertical articulated robot arm to perform the buffing process, a process that significantly impacts the quality competitiveness of products in the manufacturing process of aluminum square windows for ships. In order to eliminate incomplete polishing caused by errors in the bending and welding processes of the automatic buffing machine, the existing 360-degree rotating turntable system is eliminated, and the precision and effectiveness of the buffing process can be maximized by manufacturing an automatic buffing machine that utilizes a vertical articulated robot arm.
[0065] Furthermore, in the production of aluminum square windows, improving the working environment and automating the buffing process—which does not require highly advanced technical skills and is the most difficult process to implement manually due to dust—will not only reduce costs but also significantly improve productivity.
[0066] It is expected that they will be able to contribute. 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. [Explanation of Symbols]
