Description

Jig for making door panels and method for making door panels

The present invention relates to a jig for making door panels and a method for making door panels, in particular, a panel body is provided with a recessed portion and a protruding portion, and a jig is provided on the outer side of the recessed portion and assembled on the recessed portion, and a magnetically attracted material is combined on the surface of the protruding portion, and a magnet is provided inside the jig, so that the panel body can be firmly attracted to the jig through magnetic attraction, thereby maintaining the beauty and flatness of the panel body surface.

According to the current situation, most of the doors, indoor partitions, and building partitions in homes or businesses still use the main body of the door panel and the two sides of the main body are respectively composed of panels, and the two panels are further filled with fillers inside the main body. The fillers are used as materials for sound insulation, heat insulation, or warmth preservation, and they evolve with the times and are applied to various occasions in daily life. Many colors and styles have been derived in terms of shape and appearance. What remains unchanged is that the door panel still retains the concave or convex decorative design on the board surface to cater to the preferences of consumers.

During the filling process of the door panel, the filler will expand and swell inside the main body, causing the inner side of the panel to be squeezed outward by the filler. In addition, the concave or convex decorative designs on the surface of the door panel are unevenly compressed inside the panel, which is easy to cause expansion and deformation at the decorative design part of the panel, resulting in cracks or damage, resulting in defective products in the manufacturing process of the door panel, and thus resulting in waste of raw materials.

However, in the manufacturing process of the basic door panel, the panel is fixed to the main body by means of a jig, and the jig is supported on the surface of the panel to prevent damage when the filler is filled inside the main body. In general, the jig and the panel are positioned by sticking or gluing with tape to fix the panel on the jig for subsequent processing. After the manufacturing process of the door panel is completed, the jig will be separated from the panel, so that residual glue will be attached to the surface of the panel, and human resources and time will be consumed to remove the residual glue, which will lead to a relatively increased cost and affect the appearance and flatness of the panel surface. Therefore, there is a lack of application, which is not cost-effective and needs to be improved.

Therefore, how to solve the above problems and deficiencies is the key point that manufacturers in this industry are eager to study and improve.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information, evaluated and considered various aspects, and used his many years of experience in this industry to continuously try and modify, and finally designed this kind of jig for making door panels and the invention patent of the door panel manufacturing method.

The main purpose of the invention for manufacturing a door panel jig is that a filling space is hollowed out at the central position of the frame of the door panel, and an opening is provided on one side of the filling space on the frame, and the two plates of the door panel are respectively combined with the upper and lower sides of the frame, so that the frame forms a completely covered closed state of the filling space through the two plates, and the two plates are respectively provided with a concave portion and a convex portion corresponding to the concave portion on the surface of the two sides, and a magnetically attracted material is combined on the surface of the convex portion, so that the jig The fixture is assembled on the outer side of each recessed part of the two plates, and the number of recessed parts installed on the fixture corresponds to that of the fixture. A magnet is provided inside the fixture, so that the plate can be fixed on the fixture by magnetic attraction, so as to avoid the use of adhesive tape or other methods for positioning, thereby preventing the residual glue formed when the fixture is separated from the surface of the plate, and at the same time reducing manpower resources and time for residual glue removal, and can effectively maintain the beauty and flatness of the surface of the plate.

Another purpose of the jig for making door panels of the present invention is that the outer surface of the jig corresponds to the inner wall surface of the recessed part. When the two plates of the present invention are combined with the frame and filled with fillers, the fillers will foam and expand in the filling space, so that the protruding part is subjected to outward extrusion, so that the outer surface of the jig is closely attached to the inner wall surface of the recessed part, so that the outer surface of the jig is supported against the recessed part to prevent the protruding part on the other side from being subjected to outward extrusion and expanding, deforming or damaging, thereby achieving the effect of improving the yield rate.

Another purpose of the door panel manufacturing method of the present invention is to manufacture the door panel by sequentially performing the following steps: (A01) at least one or more recessed portions are formed on one side of two plate bodies through pre-processing, and at least one or more protrusions corresponding to the recessed portions are formed on the other side; (A02) a magnetically attracted material is bonded to the surface of each protrusion of the two plate bodies; (A03) each jig connected to the preset working equipment extends toward each plate body into the interior of each recessed portion to form a close attachment, so that the magnet of each jig can magnetically attract the magnetically attracted material on the surface of each protrusion, and each plate body is firmly positioned on the jig through the magnetic attraction; (A04) a plurality of openings are provided on the jig; and The frame is placed on the preset working equipment so that the two plates are respectively located at the hollowed-out places on the two sides of the frame; (A05) the preset working equipment drives the jigs and the two plates on the jigs to move toward the frame and combine, so that the two plates are fixed on the upper and lower sides of the frame, so that the filling space of the frame is formed into a closed state; (A06) the preset tube located outside extends into the filling space along the opening of the frame, and the filling space is filled with fillers through the preset tube; (A07) after the filling space is filled with fillers, the preset working equipment drives the jigs to separate from the recessed parts, so that the two plates and the frame are formed into a whole, thereby completing the step flow of the door panel manufacturing method.

Another purpose of the door panel manufacturing method of the present invention is to implement the following steps in sequence after implementing the step (A01) and the step (A02): (A021) aligning and tightly attaching the concave portion of one of the two plates to the outer surface of the fixture located at the lower side of the preset working equipment, so that the plate is firmly positioned on the fixture through magnetic attraction; (A022) placing the frame with the opening on the preset working equipment, and the preset working equipment drives the fixture located at the lower side and the plate on the fixture to move toward the frame and combine, thereby forming a plate fixed to the hollow part on one side of the frame; (A023) the preset working equipment positions the plate and the jig fixed to the frame of the plate body rotates so that the jig located at the lower side of the preset working equipment rotates and moves to the upper side of the preset working equipment; (A024) the concave portion of the other plate of the two plates is aligned and tightly attached to the outer surface of the jig located at the lower side of the preset working equipment, and the plate body is firmly magnetically positioned on the jig through magnetic attraction; (A025) the preset working equipment drives the jig located at the lower side and the other plate body on the jig to move toward the frame body and combine, thereby forming another plate body fixed to the hollow part on the other side of the frame body, so that the filling space of the frame body is formed into a closed state, and then continue to perform the step (A06) and the step (A07).

In order to achieve the above-mentioned purpose and effect, the technical means and structure, implementation method, etc. adopted by the present invention are described in detail in the following figure for the preferred embodiment of the present invention, so as to facilitate a complete understanding.

Please refer to Figures 1 to 5, which are the three-dimensional exploded schematic diagram of the present invention, the cross-sectional schematic diagram of the manufacturing process (I), the cross-sectional schematic diagram of the manufacturing process (II), the cross-sectional schematic diagram of the manufacturing process (III) and the cross-sectional schematic diagram of the manufacturing process (IV). It can be clearly seen from the figures that the jig for making door panels and the door panel manufacturing method of the present invention include a door panel 1 and a plurality of jigs 2 for forming the door panel 1, wherein:

The door panel 1 comprises a frame 11 and two plates 12. The frame 11 is hollowed out at the center to form a filling space 110. The filling space 110 is provided with an opening 111 on one side of the frame 11 to pass outwards. The preset tube 3 located outside can extend from the outside to the filling space 110 through the opening 111 to be filled with a filler 4 for foaming and filling. The two plates 12 are respectively combined with the hollowed-out portions on the two sides of the frame 11, and the plane dimensions of the two plates 12 are cut to correspond to the plane dimensions of the frame 11. The surface size is such that the frame 11 completely covers the filling space 110 through the two plates 12 in a sealed state, and the two plates 12 are respectively provided with at least one or more recessed portions 121 on the outer surfaces away from one side of the frame 11 toward the frame 11, so that the surfaces of the two plates 12 facing one side of the frame 11 are respectively formed with at least one or more protruding portions 122 corresponding to the recessed portions 121 toward the frame 11, and the surfaces of the protruding portions 122 are combined with magnetically attracted materials 1221.

The plurality of fixtures 2 are connected and mounted on the external preset working equipment 5 to be arranged in an upper and lower relative manner, and the plurality of fixtures 2 are assembled on the outer sides of the recessed portions 121 of the two plates 12, and the number of fixtures 2 corresponding to the recessed portions 121 of the two plates 12, and a magnet 21 is embedded in each fixture 2, wherein the outer surface of the fixture 2 corresponds to the inner wall surface of the recessed portion 121, when the two plates 12 of the present invention are combined with the frame 1 1 and using filler 4 for filling, the filler 4 will foam and expand due to filling in the filling space 110, so that the protrusions 122 of the two plates 12 are subjected to outward extrusion, and the outer surface of the jig 2 is closely attached to the inner wall surface of the recessed part 121, so that the outer surface of the jig 2 is supported against the inner wall surface of the recessed part 121 to prevent the protrusion 122 on the other side from being subjected to extrusion and expansion deformation, rupture or damage.

Please continue to refer to Figure 6, which is a step flow chart of the present invention. It can be clearly seen from the figure that the jig for making door panels and the door panel manufacturing method of the present invention include a door panel 1 and a plurality of jigs 2 for forming the door panel 1, and the manufacturing operation of the door panel 1 is implemented according to the following steps:

(A01) The two plates 12 are respectively provided with at least one or more recessed portions 121 on one side surface through pre-processing, and at least one or more protruding portions 122 corresponding to the recessed portions 121 are formed on the other side;

(A02) The surfaces of the protruding parts 122 of the two plates 12 are bonded with magnetically attracted materials 1221;

(A03) Each fixture 2 connected to the preset working equipment 5 extends toward each plate 12 into each recessed portion 121 to form a close fit, so that the magnet 21 of each fixture 2 can magnetically attract the magnetically attracted material 1221 on the surface of each protruding portion 122, and each plate 12 is firmly positioned on the fixture 2 through the magnetic attraction;

(A04) Place the frame 11 with the opening 111 on the preset working equipment 5 so that the two plates 12 are respectively located at the hollowed-out areas on the two sides of the frame 11;

(A05) The preset working device 5 drives each fixture 2 and the two plates 12 on each fixture 2 to move toward the frame 11 and combine, so that the two plates 12 are fixed to the upper and lower sides of the frame 11, so that the filling space 110 of the frame 11 is formed into a closed state;

(A06) The preset tube body 3 located outside extends into the filling space 110 along the opening 111 of the frame body 11, and the filling space 110 is filled with the filler 4 through the preset tube body 3;

(A07) After the filling space 110 is filled with the filler 4, the preset working device 5 drives each fixture 2 to separate from each recessed portion 121, so that the two plates 12 and the frame 11 are formed into a single body, thereby completing the step flow of the door panel 1 manufacturing method.

In the above step (A02), the magnetically attracted material 1221 is in the form of an iron sheet and is attached to the surface of each protrusion 122, so that the magnetically attracted material 1221 and the magnet 21 of the fixture 2 generate a magnetic attraction. Therefore, the magnetically attracted material 1221 is not necessarily designed in the form of an iron sheet. It can also be made of iron powder or other powder with magnetic attraction properties, which is applied to the surface of each protrusion 122 in the form of paint to provide the magnet 21 with a magnetic attraction. Therefore, the surface of the protrusion 122 only needs to be added with magnetic attraction properties. This simple equalization and modification does not limit the protection scope of the present invention, and it is appropriate to express it.

In the above step (A03), the jig 2 and the preset working equipment 5 can be designed to be separated, so that in the process of manufacturing the door panel 1, various patterns or designs are set on the surface of the plate body 12, and in order to match the various patterns or designs, the jig 2 can be removed from the preset working equipment 5 for replacement, so that in the process of manufacturing the door panel 1, it is not necessary to adjust the preset working equipment 5 significantly, thereby relatively reducing the assembly time and testing of the equipment, and the jig 2 is embedded with a magnet 21, so that the jig 2 can be used as a magnetic attraction through the magnet 21 and the magnetically attracted material 1221, thereby forming the plate body 12 adsorbed on the jig 2, so that the jig 2 The magnet 21 is not necessarily designed to be embedded. A recessed space can be provided inside the fixture 2 so that the recessed space is equipped with a magnet 21 or an electromagnet. The fixture 2 can be made of plastic or other materials, so that it can be quickly used to correspond to various patterns or designs of the plate 12 by injection molding or heat and pressure molding. When the main body of the fixture 2 is made of a material such as a magnet, it needs to be manufactured through complicated production to correspond to various patterns or designs of the plate 12, which will increase the production cost of the process accordingly and is not cost-effective. However, such simple equalization changes and modifications should still be included in the patent scope covered by the present invention.

In the above step (A06), the two plates 12 can be made of non-magnetic metal materials such as wood, fiberglass, plastic or melamine, and the frame 11 can be made of wood, plastic or other materials, and the frame 11 can be integrally formed or made by splicing angle materials. However, the two plates 12 and the frame 11 can be combined by bonding, etc., and the combination method is not the main technical content of the present invention, so the technical content of its component range will not be described in detail.

In the above step (A06), the filler 4 can be a material such as PE (polyethylene polymer) to provide sound insulation, heat insulation or flame retardancy for the door panel 1.

In the above steps (A03) to (A06), the order of the implementation step of combining the jig 2 with the plate 12 and the implementation step of placing the frame 11 on the preset working equipment 5 can be changed according to the process design or equipment setting. In the embodiment of the present invention, the manufacturing method of the door panel 1 is to set the plate 12 and the frame 11 to a horizontal processing type. The jig 2 can be displaced longitudinally to support the depressed portion 121. The plate 12 and the frame 11 can be changed to a vertical processing type according to the equipment setting, so that the jig 2 can be displaced horizontally to support the depressed portion 121. Such simple equal changes and modifications should still be included in the patent scope covered by the present invention.

Please continue to refer to Figure 7, which is another step flow chart of the present invention. It can be clearly seen from the figure that the main difference between another implementation step of the present invention and the aforementioned preferred implementation step is that the preset working equipment 5 can rotate and displace the multiple fixtures 2, and the frame 11 can be a movable assembly. After implementing the step (A01) and the step (A02), the following steps are implemented in sequence:

(A021) Align the recessed portion 121 of one of the two plates 12 and tightly adhere it to the outer surface of the fixture 2 located at the lower side of the preset working equipment 5, so that the plate 12 is firmly magnetically positioned on the fixture 2 through magnetic attraction;

(A022) The frame 11 with the opening 111 is placed on the preset working device 5, and the preset working device 5 drives the jig 2 located on the lower side and the plate 12 on the jig 2 to move toward the frame 11 and combine, thereby forming a plate 12 fixed to the hollow part on one side of the frame 11;

(A023) The preset working device 5 rotates the jig 2 having the plate 12 and the frame 11 fixed to the plate 12, so that the jig 2 located at the lower side of the preset working device 5 rotates and moves to the upper side of the preset working device 5;

(A024) Align the recessed portion 121 of the other plate 12 of the two plates 12 and tightly adhere it to the outer surface of the fixture 2 located at the lower side of the preset working equipment 5, and allow the plate 12 to be firmly magnetically positioned on the fixture 2 through magnetic attraction;

(A025) The preset working device 5 drives the jig 2 located on the lower side and the other plate 12 on the jig 2 to move toward the frame 11 and combine, thereby forming another plate 12 fixed to the hollow part on the other side of the frame 11, so that the filling space 110 of the frame 11 is formed into a closed state, and then continue to perform the step (A06) and the step (A07).

Therefore, the present invention has the following advantages:

1. The surfaces of the protruding parts 122 of the two plates 12 are combined with magnetically attracted materials 1221, and a magnet 21 is provided inside the fixture 2, so that the plate 12 can be firmly magnetically positioned on the fixture 2 through magnetic attraction for subsequent processing, so as to avoid the use of adhesive tape or other methods for positioning, thereby preventing the fixture 2 from being separated from the surface of the plate 12 and forming residual glue, while reducing manpower resources and time for residual glue removal, and effectively maintaining the beauty and flatness of the surface of the plate 12.

Second, when the filler 4 is filled in the filling space 110, the filler 4 will foam and expand, so that the plates 12 combined with the two sides of the frame 11 are subjected to the outward extrusion of the filler 4. The thickness of the two plates 12 is narrow, and the two plates 12 are designed in the form of a recessed portion 121 and a protruding portion 122, so that the protruding portion 122 is subjected to a larger pressure area during the filling process, thereby supporting the inner wall surface of the recessed portion 121 through the outer surface of the fixture 2 to prevent the protruding portion 122 on the other side from being subjected to the outward extrusion of the filler 4 and causing expansion, deformation or damage, thereby achieving the effect of improving the yield rate.

3. The manufacturing method of the door panel 1 of the present invention can retain the original process and the materials of the plate body 12 and the frame body 11, which can be used as the basis for setting up the manufacturing method of the present invention, and can also be quickly applied to the original process, thereby reducing the cost of changing or modifying the process and materials.

However, the above detailed description is only for a preferred feasible embodiment of the present invention, but the embodiment is not used to limit the scope of the patent application of the present invention. All other equivalent changes and modifications that are completed without departing from the technical spirit disclosed by the present invention should be included in the scope of the patent covered by the present invention.

In summary, the jig for making door panels and the method for making door panels of this invention have significant improvement in performance when used, and meet the application requirements for invention patents. Therefore, we have filed an application in accordance with the law, and hope that the review committee will approve this case as soon as possible to protect the inventor's hard work.
