Description

Technology Field

[0001] The present invention relates to a method for manufacturing a standing sign, and more specifically, to a method for manufacturing a standing sign using a 3D printer that can be easily installed on a table at an exhibition or conference room and can be easily manufactured in various forms. Background Technology

[0002] A conventional signboard for a desk is disclosed in Korean Patent Registration No. 10-2146389 and is illustrated in FIG. 1.

[0003] This consists of a lower body (100), a rib (200), and a text body (300), all of which are connected with their rear ends open. Multiple LEDs are installed in the lower body (100), and the open portion has a structure filled with epoxy.

[0004] In addition, to implement signs of various colors, epoxy of different colors is laminated and filled, and the open ends filled with epoxy are finished with acrylic sheets.

[0005] The above-described signboard for book cutting has the inconvenience of requiring NC processing of an acrylic plate to form the bottom body (100), rib (200), and text body (300), and performing side processing (curved bending, etc.) in various shapes.

[0006] In addition, since different colored epoxy is laminated and filled, color interference occurs at the boundaries between the different colored epoxy when illuminated by LEDs, making it difficult to produce a clear sign. Prior art literature

[0039] The method for producing a standing sign using a 3D printer according to the embodiment of the present invention and the sign produced thereby allow the side walls of the sign to be easily produced in various shapes, such as curved shapes, shorten the production time of the sign, enable even unskilled workers to produce the front panel (translucent resin) of the sign with a uniform thickness, and reduce color interference caused by the color difference between the side walls and the front panel when illuminated.

[0040] The method for manufacturing a standing sign and the sign of the embodiment of the present invention are as follows.

[0041] Referring to FIGS. 2 to 4 and FIG. 13, the standing sign of the embodiment of the present invention consists of a stand (100) and a stationery body mounted on the stand (100).

[0042] The above stand (100) is supported on the floor and has a horizontal support (110) on which a power supply unit (200) is mounted, and a mounting bracket (120) connected to the horizontal support (110) and on which the main body of the stationery is fixed.

[0043] Referring to FIG. 4, the stationery body is composed of a cylindrical side wall (10), a light-transmitting resin (20) disposed at one end of the side wall (10), and a rear plate (30) disposed at the other end of the side wall (10) and having a lighting module (40) fixed thereto.

[0044] The method for manufacturing the above stationery body is as follows.

[0045] First, create and save a 3D design drawing of the side wall shape to be manufactured on a computer terminal.

[0046] Referring to FIGS. 5a and 6a, a coating solution is applied to a work plate (1), such as glass, to facilitate the subsequent separation of the side wall (10).

[0047] Next, referring to FIGS. 5 and 6, a filament printed by a 3D printer according to the 3D design is stacked on a work plate (1) to form a side wall (10).

[0048] As shown in FIGS. 6a and 6b, the filament output by the head (2) of the 3D printer is sequentially stacked on the work plate (1) to form a side wall (10) according to the 3D design.

[0049] The filaments are stacked in a loop shape to form a side wall (10).

[0050] Referring to FIG. 5a and FIG. 13, the side wall (10) can be formed by laminating filaments (10a, 10b) of different colors with different light transmittances to enhance the visual effect of the signboard.

[0051] Referring to FIG. 5b and FIG. 7, when the side wall (10) is completed, a transparent resin (20) is applied to the work plate (1) on the inner side of the side wall (10) with a predetermined thickness.

[0052] The above side wall (10) and transparent resin (20) are placed on the above work plate (1) and cured through a UV curing machine.

[0053] Meanwhile, referring to FIG. 8, a lighting module (40), such as an LED strip, is attached to the rear plate (30) attached to the end of the side wall (10).

[0054] Referring to FIG. 5c, the hardened side wall (10) and the transparent resin (20) are separated from the work plate (1), and the back plate (30) is attached to the open end of the side wall (10).

[0055] At this time, the lighting module (40) irradiates light in the direction of the cured transparent resin (20).

[0056] Figure 9 shows a sample photo of a stationery body produced by a 3D printer.

[0057] The stationery body produced as described above is manufactured in a tubular shape (loop shape) by stacking 3D printer filaments so that the upper and lower parts of the side wall (10) are penetrated, and a transparent resin (20) is applied to the bottom of the work plate (1) and cured to form the front plate, thereby shortening the production time of the stationery body and making production easier.

[0058] FIGS. 10a and FIGS. 10b show other examples of the method for manufacturing a stationery body according to the present invention.

[0059] This involves forming a boundary rib (11) by protruding it toward the lower inner surface of the side wall (10) while forming a side wall (10) by stacking filaments of the 3D printer, and the boundary rib (11) is formed spaced apart from the work plate (1).

[0060] In the step of applying the above-mentioned transparent resin (20), the above-mentioned transparent resin (20) is applied up to the boundary rib (11) as shown in FIG. 10b.

[0061] In this case, even an unskilled person can produce the transparent resin (20) constituting the front panel of the signboard with a uniform thickness, and the boundary rib (11) can block and reduce color interference caused by the color difference between the side wall (10) and the transparent resin (20) when the lighting module (40) is illuminated.

[0062] Referring to Fig. 11, which shows a method of manufacturing another example,

[0063] This involves forming a support rib (12) by protruding it toward the upper inner surface of the side wall (10) while forming the side wall (10) by stacking the filament of the 3D printer, and the support rib (12) is formed spaced apart from the top of the side wall (10).

[0064] The rear plate (30) is attached to the support rib (12).

[0065] The above rear plate (30) is formed by stacking filaments printed with a 3D printer, thereby enabling improved assembly precision of the rear plate (30) that is coupled to the side wall (10) and the support rib (12).

[0066] Referring to FIG. 12a and FIG. 12b, which illustrate another example of a manufacturing method, a concave groove (13) is formed on the lower inner surface of the side wall (10) while the filament of the 3D printer is being stacked to form the side wall (10), wherein the concave groove (13) is formed between the work plate (1) and the boundary rib (11).

[0067] In this case, the transparent resin (20) is applied by entering the concave groove (13), so that the subsequently cured transparent resin (20) can be firmly bonded to the side wall (10) without detaching.

[0068] Meanwhile, a transparent filament can be layered on the surface of the cured transparent resin (20) using the 3D printer to form a three-dimensional pattern of a predetermined pattern. In this case, the effect of the three-dimensional sign can be further enhanced through the transparent resin (20) through which light passes.

[0069] As shown in FIGS. 2 to 4, the stationery body produced as described above forms a protruding ridge (121) on the mounting base (120) and mounts the end of the side wall (10) by joining it to the protruding ridge (121). The lighting module (40) is connected to the power supply unit (200) and operates.

[0070] Meanwhile, the stationery body produced as described above can be fixed to the mounting base (120) with a bolt (300) as shown in FIGS. 14 and 15. Explanation of the symbols
