Description

Method of manufacturing pannel door panel

The present invention relates to a method of manufacturing a door panel for a storage closet, and more particularly, to a method for manufacturing a door panel for a storage closet having a structure in which film papers having different patterns are attached in a mosaic manner.

Storage doors For example, a sink door is generally used by attaching a patterned film to a substrate such as medium density fiberboard (MDF) or high density fiberboard (HDF). Film paper with a printed pattern is usually a sheet of paper, such as LPM or HPM is used as a sheet of paper that is printed with a variety of color patterns printed on the melamine resin and then dried.

However, in the related art, one film paper attached to a substrate is used, and various patterns may be difficult to express and implement.

On the other hand, there is a method in which a film of a predetermined color is coated on the substrate and then the film paper is attached so that the part coated with the paint is partially exposed. There is a disadvantage in that the work efficiency is lowered because the film must be attached after applying the adhesive.

In addition, it may be considered to cut each of the films in a mosaic manner and then attach them to the substrate, but in this case, there is a problem that it is not easy to attach the film pieces to each other precisely at the corresponding positions, which makes it difficult to work.

The present invention was devised to improve the above problems, and an object thereof is to provide a manufacturing method of a door panel for a cabinet that can be reproducibly attached in a desired pattern to different film papers.

In order to achieve the above object, the manufacturing method of the door panel for the cabinet according to the present invention comprises the steps of sequentially forming at least one concentrically independent bone concentrically on the upper surface of the substrate; Applying an adhesive to the entire upper surface of the substrate; Sequentially stacking film papers corresponding to the outer line areas partitioned by the valleys and having different patterns, starting from the innermost area for each area partitioned by the valleys; Treating each film sheet to be attached to the substrate by the adhesive; And clipping the overlap area of the film paper not coated with the adhesive.

The adhesive application step is preferably applied to the top and side surfaces of the substrate.

The method may further include attaching a film of a predetermined color to a lower surface of the substrate before the bone forming step.

More preferably, in the film paper stacking step, the film paper laminated in the lower order is applied with at least one hole in which a portion of the film paper stacked in the prior order is exposed.

Hereinafter, a manufacturing method of the door panel for the cabinet according to a preferred embodiment of the present invention with reference to the accompanying drawings.

1 is a perspective view showing an example of a door panel for the cabinet according to the invention, Figure 2 is a cross-sectional view taken along the line A-A of FIG.

Referring to the drawing, the cabinet door panel 10 includes a substrate 11, a first film layer 13, a second film layer 14, and a third film layer 15.

The substrate 11 may be a material capable of attaching a film paper while having a strength that can be applied for a door, and a medium density fiber board (MDF) or a high density fiber board (HDF) generally used is preferably applied.

The film paper 12 of predetermined color is affixed on the lower surface of the board | substrate 11. Alternatively, the lower surface of the substrate 11 may be coated with a paint.

On the upper surface of the substrate 11, a plurality of valleys 21 and 22 are sequentially spaced concentrically and form a closed trajectory. In the following description, the orders of the valleys 21 and 22 are sequentially given in the order of enclosing from the center to the outside and correspond to the stacking order on the substrate 11.

The width, the track shape and the number of the valleys 21 and 22 may be formed in various ways depending on the shape of the pattern to be implemented.

The portions defined by the valleys 21 and 22 form a pattern. In addition, the valleys 21 and 22 form a predetermined angle with the upper surface so that they can be used as a boundary portion where the different film papers are bonded to each other so that the joints between the film papers can be processed so as not to protrude too much. That is, the portions marked C1 and C2 in FIG. 2 are attached to the second film layer 14 to be in contact with the first film layer 13, but are finished in a form of slightly covering the edges of the first film layer 13, The portions marked C3 and C4 are attached to the third film layer 15 to be in contact with the second film layer 14, but are finished in a form that slightly covers the edge of the second film layer 14.

In such a structure, a user's hand moves relatively from the edge of the panel 10 toward the center portion of the panel 10 after the handle is attached to the door, and the panel 10 is relatively in contact with the film layer 13. 14 and 15 are bonded to each other in the direction in which the joints are pressed, that is, in the direction in which the bone formation order is low, so that separation of the boundary portions of the film layers 13, 14 and 15 is suppressed. .

A manufacturing process of the cabinet door panel 10 having the above structure will be described in more detail with reference to FIGS. 3 and 10. Hereinafter, the case of using an MDF substrate will be described.

First, as shown in FIG. 4, the film paper 12 is attached to the bottom surface of the substrate 11.

Next, as shown in FIG. 5, at least one valley 21 or 22 corresponding to a pattern of a desired shape is formed on the upper surface 11a of the substrate 11. The formation of the troughs 21 and 22 uses an numerical control machine (NC) as an example.

Then, the adhesive 23 is applied to the upper surface 11a or the upper surface 11a and the side surface 11b of the substrate 11. Preferably, as shown in FIG. 6, the adhesive 23 is applied to the entire upper surface 11a and the entire side surface 11b of the substrate 11.

As the adhesive 23, it is preferable to use a thermosetting adhesive capable of adhering a film sheet by heat and compression at a predetermined temperature. Thermosetting adhesives are used in various ways, detailed description thereof will be omitted.

Subsequently, as illustrated in FIG. 7, the film paper corresponding to the first film layer 13 manufactured in a shape corresponding to the inner region partitioned by the innermost primary valley 21 is formed in the primary valley 21. Place it in the area partitioned by. Hereinafter, the film paper corresponding to the first film layer is denoted by the same reference numeral because no separate cutting process is performed.

Next, the second film paper 14a produced in the shape corresponding to the area partitioned by the next valley 22 is placed in accordance with the area partitioned by the secondary valley 22 (see Fig. 8). Preferably, as shown in FIG. 3, when the second film paper 14a having a shape corresponding to the outer line of the secondary valley 22 is placed on the corresponding area of the substrate 11, the first film paper 13 It is preferable to apply a cut treatment having at least one hole 14b so that a portion is exposed. The shape of the holes 14b formed in the second film paper 14a, which is a laminated film paper, stacked on the first film paper 13, which is a laminated film paper, is smaller than the outer shape of the first film paper 13, which is laminated, but is laminated. It is only necessary to expose a part of the first film paper 13 in the state, and it is not necessary to necessarily correspond to the outer shape of the first film paper 13 pre-laminated.

In this case, the cutting operation of the portion to be cut non-bonded with the adhesive 23 in the cutting process described later becomes much easier.

In the next process, as shown in FIG. 9, the third film paper 15a that can cover the edge region of the substrate 11 from the secondary valley 22 is placed on the corresponding position of the substrate 11. Even in the case of the third film 15a, at least one hole 15b is exposed so that a part of the second film 14a is exposed when the third film 15a is placed on the corresponding area of the substrate 11 for ease of cutting. It is preferable to apply the cut with a).

Then, the film sheets 13, 14a, 15a are attached to the substrate 11 by the adhesive 23 by thermocompression bonding.

Subsequently, as shown in FIG. 10, a portion of the third film 15a overlapped with the adhesive 23 is not applied, that is, the second film 14a overlapped on the second film 14a. And forming a second film layer 14 by cutting a part of the second film paper 14a overlapped on the first film paper 13 to form the second film paper attaching door panel having the structure shown in FIG. Is completed. Here, it is preferable to cut | disconnect so that the part which mutually borders among each film paper 13 (14a) 15b overlaps slightly.

For reference, in FIG. 9 and FIG. 10, the adhesive 23 is initially maintained during the thermocompression process, and then slightly along the gap between the boundary portions of the film paper 13, 14a and 15a by thermocompression. It is marked in bold to show entry.

The door panel manufactured by such a manufacturing method is to cut each film sheet 13, 14a, 15a prepared by cutting to correspond to the outer line of the region to be attached to each film sheet by an operation of sequentially placing the film sheets in the corresponding region according to the order. It is possible to easily adjust the alignment of the multi-tone door panels using different types of film papers of different colors and patterns.

In the above description, a case in which three dissimilar film papers are sequentially stacked and cut is described. However, even if three or more film papers are to be applied, the above-described process may be manufactured by lamination orders corresponding to the bones according to the above-described process.

In addition, when there are a plurality of bones formed to be spaced apart from each other within a predetermined degree of bone, the same order may be applied to each of the bones, and the above-described processes may be manufactured according to the corresponding order.

As described so far, according to the manufacturing method of the door panel for the cabinet according to the present invention, it is possible to increase the reproducibility of the process for attaching the heterogeneous film paper to the substrate by mosaic-shape, and to provide ease of operation.
