Description

[Technical field]

[0001] The present invention relates to an automatic buffing device for aluminum square windows for ships, and more particularly, to an automatic buffing device for aluminum square windows for ships that uses a vertical articulated robot arm to perform a buffing process that determines the quality competitiveness of products 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 existing 360-degree rotation turntable method has been eliminated, and the automatic buffing machine uses a vertical articulated robot arm to maximize the precision and effectiveness of the buffing process.

[0002] According to the present invention, the manufacturing of aluminum square windows does not require high technical capabilities, and in the buffing process where manual labor is the most difficult due to poor working conditions caused by dust, a dust suction port is installed close to the polishing machine to suck in dust, improving the working environment and automating the process, which is expected to greatly contribute to cost reduction as well as productivity improvement. [Background technology]

[0003] Aluminum square window covering means a finished product for an aluminum window, as shown in FIG.

[0004] Such an aluminum square window cover usually has a width of 400 to 600 cm, a length of 300 to 450 cm, and a thickness of 0.5 to 0.7 cm, and is made of aluminum material, which is convenient for processing and deformation.

[0005] Such an aluminum square window cover is manufactured by banding an aluminum flat plate, performing an aluminum welding operation, performing a straightening operation, performing a hole processing, and then performing an anodizing coating operation, and then installing it on an aluminum window frame.

[0006] However, when processing the entire surface and sides of an aluminum square window cover with a sandpaper grinder while holding it in the hand, the worker must adjust his / her strength while working, which can result in uneven processing depending on the individual's strength and ability. In addition, as shown in Figure 2, there is also the problem that the aluminum square window cover can be deformed when processed by holding it in the hand.

[0007] There is also the problem that the high speed rotation of the sandpaper machine poses a safety risk to the worker.

[0008] That is, in the process of machining the aluminum rectangular window, since the worker performs the polishing work manually, problems occur in that the machined surface is not uniform depending on the worker's level of skill, or the polishing of the aluminum rectangular window must be repeated due to poor workmanship, and furthermore, the high rotation speed of the buffing machine poses a threat to the safety of the worker, which may be a factor in inducing industrial accidents.

[0009] In addition, since the buffing process is performed manually, it is difficult to standardize product quality and increase production volume. Therefore, a solution to overcome this problem is required.

[0010] Therefore, we are trying to develop an automatic robot buffing machine for aluminum square windows that can band and weld the chassis, which is the core material of aluminum square windows, perform automatic clamping according to the standard, and then perform the buffing work process using a vertical articulated robot arm.

[0034] FIG. 7 is a diagram showing a table of an automatic buffing device for aluminum square window for ships according to the present invention.

[0035] Here, Figure 9 is an enlarged view of the fixing area of ​​the square window on the table of Figure 7, and Figure 9 is a view showing the configuration of a cylinder fixing device that fixes the square window on the table of the automatic buffing apparatus for aluminum square windows for marine use according to the present invention.

[0036] First, referring to FIG. 1 of the accompanying drawings, an automatic buffing device for aluminum square windows for ships according to the present invention (hereinafter referred to as “buffing device 10 ”) comprises a robot arm 11 and a table 12 .

[0037] The robot arm 11 is an arm-type robot that is configured with multiple joints and is driven, and a polisher 119 for a buffing process is connected to the end of the robot arm 11. The polisher 119 is not shown in FIG. 3, but is illustrated in FIG. 6.

[0038] A table 12 is arranged adjacent to one side of the robot arm 11, and an aluminum square window 124 is attached and fixed to the table 12. When 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 arranged with multiple joints and driven to move along the upper surface of the table 12.

[0039] The robot arm 11 will now be described with reference to Figures 4, 5 and 6 of the accompanying drawings.

[0040] The robot arm 11 includes a body 112 that is configured on the upper surface of the base 111 and has a motor therein, a rotor 113 that is connected to the upper side of the body 112 and connected to the motor of the body 112 to receive a rotational force, a support 114 that is connected to the upper side of the rotor 113 and rotates by the rotational force of the rotor 113, a first arm 115 that is connected to a motor that receives power (electricity, air, hydraulics, etc.) at one side of the support 114 and rotates at a predetermined angle from the support 114 with the motor as a reference axis, and an auxiliary arm 116 having a cylinder configuration, both ends of which are connected from the other side of the support 114 to one side of the first arm 115 via hinges.

[0041] That is, when the first arm 115 rotates around a reference axis, 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 ordinary engineers, and referring to FIG. 4 of the attached drawings, it is sufficient if it includes a reference structure that is coupled to the upper surface of the body 112 and a rotating structure that contacts the reference structure and is coupled to the shaft of a motor to rotate.

[0043] In addition, although the present invention does not describe in detail the hydraulic connection structure for driving each arm configuration, a person of ordinary skill in the art would be able to easily apply the hydraulic line connection structure.

[0044] In other words, the main feature of the present invention is that it uses a multi-joint robot arm having an arm structure and can approach a table by rotating or rotary driving each joint. Since the hydraulic connection structure for driving the robot arm will be clear to a person of ordinary skill in the art, it will not be described in further detail.

[0045] 5, a connecting member 117 is connected to the other end of the first arm 115 using a motor that rotates by receiving a separate power. The connecting member 117 can rotate at a predetermined angle from the first arm 115 based on the axis of the motor provided at the other end of the first arm 115.

[0046] A second arm 118 extends from one side of the connecting body 117. The second arm 118 is configured to be connected to the shaft of a motor provided on the other side of the connecting body 117, so that the second arm 118 can rotate in a 360° direction by the rotation of the motor of the connecting body 117.

[0047] In addition, a front end rotating arm 118a connected to a motor is formed at one end of the second arm 118, and the front end rotating arm 118a can be rotated to a predetermined angle by the rotation of the motor.

[0048] A grinder 119 is vertically coupled to the end of the front end rotating arm 118a.

[0049] A robot arm 11 having such a configuration can rotate in all directions by the rotating body 113, the first arm 115 can rotate in the front-to-rear direction at a predetermined angle, and the second arm 118 can rotate in the up-down direction from the first arm 115 at a predetermined angle, the second arm 118 can rotate about an axis by the motor of the connecting body 117, and the front-end rotating arm 118a can also rotate at a predetermined angle, so that it has the advantage of being able to respond to multiple joint directions on the top surface of the table 12.

[0050] The table 12 will be described with reference to the accompanying drawings, FIGS.

[0051] The table 12 includes 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 square window 124 fixed by the cylinder fixing device 123.

[0052] Here, the transport means 122 functions to transport the transport plate 1223 in a predetermined direction on the upper surface of the table body 121, and may include a predetermined conveyor belt, but as shown in the attached Figure 4, it is configured in a cylindrical shape on one side of the table body 121, the rod of the cylinder is the transport body 1221, a guide body 1222 is connected vertically upward to one side of the transport body 1221, and the transport 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] That is, although FIG. 7 shows two transfer plates 1223, this is a diagram showing a state in which the transfer plates 1223 have been moved.

[0055] The reason why one or more cylinder fixing devices 123 are provided is that the rectangular window 124 is fixed in at least two directions on the upper surface of a single conveying plate 1223 .

[0056] As shown in FIG. 8 of the attached drawings, the cylinder fixing device 123 includes a rod 1231 and a square window fixing part 1232 at the end of the rod 1231, so that the horizontal fitting hole ( A rectangular window 124 having a rectangular (99) shaped end is supported at the lower end of the protruding region.

[0057] Meanwhile, although not indicated by a reference number, auxiliary supports having the same or lower height as the square window fixing part 1232 may be configured perpendicularly to the square window fixing part 1232 on both sides of the square window fixing part 1232. Such auxiliary supports are provided to ensure a supporting force for fixing the square window 124 even when pressed from above when performing a buffing process using the polisher 119.

[0058] Such a cylinder fixing device 123 will be described with reference to FIG.

[0059] As shown in the top view of Figure 9, the cylinder fixing device 123 includes a U-shaped holder 12311 having a U-shape, a rotating part 12313 whose end is located in the internal hollow of the U-shaped holder 12311 and connected via a hinge 12312, and an extension body 12314 connected to the end of the rotating part 12313, and a square window fixing part 1232 is vertically connected to the end of the extension body 12314.

[0060] Meanwhile, as another example, as shown in the lower end of FIG. 8, the square window fixing portion 1232 may be configured with two auxiliary rotation portions 12321 symmetrically arranged in one direction in addition to the plate portion configuration.

[0061] As a result, a hollow 12322 is formed between the two auxiliary rotating parts 12321, and the other end of the extension body 12313 is inserted into the hollow 12322 and joined via a hinge.

[0062] Here, the hinge connecting the extension and the auxiliary rotating part may further include a torsion spring.

[0063] In addition, by combining and connecting a motor and a gear 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 rise or fall based on the cylinder fixing device 123. When the extension body 12314 rises, the square window fixing part 1232 rotates slightly to support the square window 124 in a vertical direction, which is useful when the height of the square window 124 needs to be adjusted slightly.

[0064] According to the automatic buffing apparatus for aluminum square windows for ships according to the present invention configured as described above, in the manufacturing process of aluminum windows for ships, the automatic buffing apparatus performs the buffing process, which determines the quality competitiveness of the product, by using a vertical articulated robot arm. In order to eliminate incomplete polishing due to errors in the bending and welding processes of the automatic buffing machine, the existing 360-degree rotating turntable method is eliminated, and the precision and effectiveness of the buffing process can be maximized by manufacturing an automatic buffing machine using a vertical articulated robot arm.

[0065] In addition, in the manufacture of aluminum square windows, it does not require high technical skills, and the buffing process is the most difficult to employ manually due to poor working conditions caused by dust. By improving the working environment and automating the process, it is possible to reduce costs and greatly improve productivity.

[0066] It is expected that this will be possible. The above description based on the attached drawings discloses only the main points of the present invention, and since various designs are possible within the technical scope, it is clear that the present invention is not limited to the configuration of the drawings.
