Description

Method for manufacturing magnet charging type cell phone case}

The present invention relates to a method of manufacturing a glass case for a magnetic rechargeable mobile phone. In particular, it can prevent the magnetic force from weakening or reducing charging efficiency during wireless charging, as well as eliminate the risk of losing the magnet module, and in particular, improve the appearance of the case. This relates to a method of manufacturing a magnetically rechargeable cell phone glass case that can increase durability by preventing the case from discoloring yellow due to light while creating a flashy appearance.

Wireless charging technology is used for simple and fast charging of mobile phones, etc. One of these technologies is the recently released wireless charging connector that supports wireless charging, also called MagSafe, especially for certain models. These wireless charging connectors use magnets to connect wirelessly to the mobile phone and then charge the mobile phone wirelessly. For reference, MagSafe wireless charging refers to the name of the technology standard for accessories for magnetically attached iPhones.

Meanwhile, if you charge your mobile phone by attaching it directly to the wireless charging connector mentioned above, there will be no problem with charging. However, wireless charging is difficult if you cover your expensive phone with a phone case to protect it. For this reason, cell phone cases incorporating wireless charging technology have been manufactured recently.

In particular, these cell phone cases are equipped with technology that magnetically adheres to the wireless charging connector and prevents them from being separated arbitrarily during charging. Cases equipped with this technology are called magnetic rechargeable cell phone glass cases.

A method of manufacturing a conventional magnetic rechargeable mobile phone glass case will be described.

First, a magnet module groove into which a MagSafe magnet module can be inserted is machined on the inner surface of the case.

Then, insert the MagSafe magnet module (hereinafter referred to as magnet module) into the module insertion groove of the case. Afterwards, the inserted magnet module is manufactured by attaching a sticker so that it cannot be separated and is not visible. At this time, the sticker used mainly takes the form of a white strip and is attached to the back of the case.

However, the manufacturing method of the conventional magnetic rechargeable mobile phone glass case manufactured in this way causes the following problems due to its structural or methodological limitations.

First, cases are generally made by nc (numerical control) processing of PC (polycarbonate) material. When the module insertion groove is processed in such cases, the thickness is thin, which causes damage due to injection pressure, increasing the defect rate. There is a problem. Accordingly, increasing the thickness of the case may be considered, but simply increasing the thickness of the case may widen the gap between the wireless charging connector and the magnet module, weakening the magnetic force, and also causing a problem of reduced charging efficiency.

Second, there is a problem that the sticker attached to protect the magnet module inserted into the module insertion groove may fall off and the magnet module may be lost from time to time.

Third, since the finishing process is mainly done with stickers in the form of a white strip, it is difficult to form various colors and patterns on the case for decoration, which makes it difficult to enhance the beauty of the exterior of the case.

To solve this problem, the applicant has previously applied for a patent for the invention of a 'magnetic rechargeable cell phone case', and is currently undergoing examination.

However, since the above-mentioned previously filed invention does not apply a means to prevent discoloration, when used for a long period of time, the value of the product may decrease as the case turns yellow due to light, so there is a need to develop technology to supplement this.

The flowchart of the case manufacturing method, Figures 4 to 8 are process diagrams of part of the manufacturing method of Figure 3, and Figures 9 to 13 are cross-sectional views of the product of the corresponding process corresponding to Figures 4 to 8.

Referring to these drawings, the present invention can prevent the magnetic force from weakening or charging efficiency from decreasing during wireless charging, and also eliminates the risk of losing the magnet module (140) by not using a sticker. Accordingly, the exterior can be created splendidly, thereby enhancing the beauty of the exterior of the case 100.

The present invention, which can provide these effects, is applicable to the magnetic rechargeable mobile phone glass case 100 as shown in FIGS. 1 and 2, and the method of manufacturing the magnetically rechargeable mobile phone glass case as shown in FIGS. 3 to 13. You can.

Referring to Figures 1 and 2, the magnetic rechargeable mobile phone glass case 100 according to this embodiment inserts a magnet module 140, that is, a MagSafe magnet module (140), into the case plate 110. It is manufactured in the form of Of course, unlike the conventional case, the magnet module 140 is inserted from the outside of the case, and the decorative exterior sheet 161 is further placed on top of it, providing the advantage of printing or design expression. For this example, a dog was selected as the design expression. Of course, unlike drawings, it is okay to use other forms of design expression.

The case plate 110 is an external structure of the magnetic rechargeable mobile phone glass case 100 according to this embodiment. The case plate 110 is made of transparent polycarbonate material. In this embodiment, the thickness of the case plate 110 is 1.1 mm to 1.3 mm. If the thickness of the case plate 110 is thinner than 1.1 mm, processing of the module insertion groove 120 is difficult, and if the thickness of the case plate 110 is thicker than 1.3 mm, the magnetic force becomes weak. Therefore, it is advantageous for the case plate 110 to have a thickness of 1.1 mm to 1.3 mm, preferably 1.2 mm.

A module insertion groove 120 is formed in the case plate 110. The module insertion groove 120 may be performed by an NC machine (170, numerically controlled machine). It is advantageous for the depth of the module insertion groove 120 to be 0.8 mm to 1.0 mm, preferably 0.9 mm.

Since the case plate 110 is made of transparent polycarbonate material as described above, when the magnet module 140 is inserted into the module insertion groove 120 of the case plate 110, the inserted magnet module 140 is visible.

If the magnet module 140 is visible like this, the beauty of the exterior may deteriorate in some cases. Accordingly, an opaque forming material 130 is provided to cover this, that is, to make it invisible even though the magnet module 140 is inserted. The opaque forming material 130 is provided on the bottom surface of the module insertion groove 120 so that the bottom surface of the module insertion groove 120 becomes opaque. At this time, the opaque forming material 130 may be an opaque adhesive tape 130 made of an opaque material.

After the opaque forming material 130, which is the opaque adhesive tape 130, is provided or attached to the bottom surface of the module insertion groove 120, the magnet module 140 is inserted thereon. As described above, the magnet module 140 is a module that is inserted into the module insertion groove 120 on the opaque forming material 130 and is magnetically attached to the wireless charging connector. That is, in this embodiment, the magnet module 140 is a MagSafe magnet module (140).

After the magnet module 140 is inserted, UV (ultraviolet rays) liquid 150 is applied and cured. That is, the UV liquid 150 is applied and cured to the area of the magnet module 140 so that the magnet module 140 is covered.

In addition, a cell (160) is formed by laminating a decorative exterior sheet (161) that allows printing or design expression on the layer formed by curing the UV liquid (150) and glass (162) that prevents discoloration. ) are combined.

The design expression of the dog picture shown in FIG. 1 is formed on the decorative exterior sheet 161, and since the decorative exterior sheet 161 is disposed on the outer surface, the beauty of the decorative appearance of the case can be improved. In particular, since the magnet module 140 inserted inside is not visible, the beauty of the exterior can be prevented from being reduced.

In addition, since the glass 162 is laminated on the outside of the decorative exterior sheet 161, the case 100 can be prevented from turning yellow due to light. Therefore, the case 100 can be used for a long period of time.

Meanwhile, this magnetic rechargeable mobile phone glass case 100 can be manufactured by the method below for mass production. That is, the method of manufacturing a magnetic rechargeable mobile phone glass case according to this embodiment includes a case plate preparation step (S110), a module insertion groove processing step (S120), an opaque forming material preparation step (S130), a magnet module insertion step (S140), and a UV It may include a liquid application step (S150), a UV liquid curing and flatness adjustment step (S161), a case plate cutting step (S170), a cell lamination step (S180), and a case molding step (S190).

The case plate preparation step (S110) is a process of preparing the case plate 110 as shown in FIG. 4. As previously described, the case plate 110 is made of transparent polycarbonate. Additionally, the case plate 110 is formed to be relatively thicker than the thickness of the wireless charging connector and the magnet module 140 to be magnetically attached. That is, in this embodiment, the thickness of the case plate 110 may be 1.1 mm to 1.3 mm, preferably 1.2 mm.

The module insertion groove processing step (S120) is a process of machining the module insertion groove 120 into which the magnet module 140 will be inserted into the case plate 110 prepared as shown in FIG. 4. The module insertion groove processing step (S120) can be performed by an NC machine (170, numerically controlled machine). Therefore, fast and accurate processing can be achieved. As previously described, in this embodiment, the depth of the module insertion groove 120 may be 0.8 mm to 1.0 mm, preferably 0.9 mm.

The module insertion groove 120 consists of a set of a circular groove portion 120a and a linear groove portion 120b. The corresponding magnet module 140 is inserted into both the circular groove 120a and the linear groove 120b. At this time, the magnet module 140 inserted into the linear groove portion 120b serves to prevent random rotation of the case.

In the case of this embodiment, it is shown that six module insertion grooves 120 are formed in one case plate 110. In this case, there is an advantage of being able to make a total of 6 magnetic rechargeable cell phone glass cases (100) at once. Of course, the scope of the present invention is not limited to this number.

The opaque forming material preparation step (S130) is a process of providing an opaque forming material 130 on the bottom surface of the module insertion groove 120 so that the bottom surface of the module insertion groove 120 can become opaque, as shown in FIG. 5. As described above, in this embodiment, the opaque forming material 130 is applied as an opaque adhesive tape 130 made of an opaque material. Therefore, the step of preparing an opaque forming material (S130) may be a step of attaching the opaque adhesive tape 130 to the bottom surface of the module insertion groove 120. When the opaque adhesive tape 130 is attached in this way, the bottom surface of the module insertion groove 120 may become opaque due to the opaque adhesive tape 130. Therefore, the magnet module 140 inserted here is not visible from the outside.

The magnet module insertion step (S140) is a process of inserting the magnet module 140 into the module insertion groove 120 on the opaque forming material 130 as shown in FIG. 6. Since the module insertion groove 120 is made up of a set of a circular groove portion 120a and a linear groove portion 120b, although not shown, the magnet module 140 also has a shape corresponding to the circular groove portion 120a and the linear groove portion 120b. It can be made and inserted into the corresponding groove portions 120a and 120b, respectively. The magnet module 140 is inserted from the outside of the case plate 110. Since the magnet module 140 is inserted from the outside, the magnet module 140 must be inserted correctly in the front and back direction.

The UV liquid application step (S150) is a process of applying UV (ultraviolet rays) liquid 150 to the area of the magnet module 140 so that the magnet module 140 is covered as shown in FIG. 7. The liquid UV solution 150 is applied to cover the entire exposed surface of the magnet module 140, including the space of the module insertion groove 120 remaining after the magnet module 140 is inserted.

The UV liquid curing and flatness control step (S161) is a process of curing the applied UV liquid 150 as shown in FIG. 7 and controlling the flatness of the UV liquid 150. The UV liquid curing and flatness control step (S161) can be performed by a heating roller (180). That is, the action of the heating roller 180 allows the UV liquid 150 to be hardened, while also allowing the layer of the cured UV liquid 150 to be flattened without being uneven.

The cell lamination step (S180) is a decorative exterior sheet 161 that can print or express a design on the layer formed by curing the UV liquid 150 as shown in Figure 8 and a glass 162 that prevents discoloration. This is a process in which the laminated cells 160 are laminated.

The decorative exterior sheet 161 may be a type of printable film. In the case of this embodiment, a dog picture was printed on the decorative exterior sheet 161. Additionally, the glass 162 is disposed on the outside of the decorative exterior sheet 161 to prevent discoloration.

At this time, in the case of this embodiment, rather than laminating the decorative exterior sheet 161 and the glass 162 in order, the decorative exterior sheet 161 and the glass 162 are laminated through another process to form a single body (cell ( Since it is a method of taking 160) and laminating them, the convenience of the laminating process increases and the time can be shortened.

As described above, the design expression of the dog picture shown in FIG. 1 is formed on the decorative exterior sheet 161, and the glass 162 is laminated on the outside of the decorative exterior sheet 161.

In this way, since the decorative exterior sheet 161 is disposed on the outer surface and the glass 162 is disposed on the outer surface, the beauty of the decorative exterior can be improved and the case 100 can be prevented from being discolored yellow by light. there is.

Meanwhile, as described above, the cell 160 is a sheet in which the decorative exterior sheet 161 and the glass 162 are laminated, and the cell 160 is applied using an optically clear adhesive (OCA) or an ultraviolet rays (UV) adhesive. As shown in Figure 8, the UV liquid 150 can be cured and laminated onto the formed layer.

At this time, when laminating the cells 160 using OCA, they can be made as semi-finished products and then laminated. In addition, when laminating the cell 160 with UV adhesive, it can be laminated one-to-one with the case plate 110 into which the magnet module 140 is inserted, rather than a semi-finished product, and then proceed with post-processing to complete the cell 160 into a finished product.

The case plate cutting step (S170), not shown, is a process of cutting the case plate 110 into case unit plates (not shown) of unit size before performing the cell lamination step (S180). In this embodiment, one case plate 110 can be cut into a total of six case unit plates. Depending on the embodiment, the cell lamination step (S180) may be performed, and the case plate cutting step (S170) may be performed. .

Of course, in the case of this embodiment, since several module insertion grooves 120 are formed in a single case plate 110, the case plate cutting step (S170) is applied. However, if one magnetic rechargeable mobile phone glass case 100 is made from a single case plate 110, the case plate cutting step (S170) is not necessary.

The case forming step (S190), which is not shown, is a process of forming a case using a case unit plate. In other words, by going through this step, a practical magnetic rechargeable mobile phone glass case 100 as shown in FIG. 1 can be made.

Hereinafter, the process for manufacturing the magnetic rechargeable mobile phone glass case 100 will be described in turn.

First, prepare a case plate 110 made of transparent polycarbonate material as shown in Figure 4. As described above, in this embodiment, six magnetic rechargeable mobile phone glass cases 100 can be made with one case plate 110. The thickness of the case plate 110 may be 1.1 mm to 1.3 mm, preferably 1.2 mm.

Next, the module insertion groove 120 into which the magnet module 140 will be inserted is machined into the case plate 110 prepared as shown in FIG. 4 using an NC machine (170, numerically controlled machine). The depth of the module insertion groove 120 to be processed may be 0.8 mm to 1.0 mm, preferably 0.9 mm.

Next, as shown in FIG. 5, an opaque adhesive tape 130 is attached as an opaque forming material 130 to the bottom surface of the module insertion groove 120 so that the bottom surface of the module insertion groove 120 becomes opaque. When the opaque adhesive tape 130 is attached in this way, the bottom surface of the module insertion groove 120 may become opaque due to the opaque adhesive tape 130. Therefore, the magnet module 140 inserted here is not visible from the outside.

Next, the magnet module 140 is inserted into the module insertion groove 120 on the opaque forming material 130 as shown in FIG. 6. The magnet module 140 is inserted from the outside of the case plate 110. Since the magnet module 140 is inserted from the outside, the magnet module 140 must be inserted correctly in the front and back directions.

Next, UV liquid 150 is applied to the area of the magnet module 140 so that the magnet module 140 is covered as shown in FIG. 7. The liquid UV solution 150 is applied to cover the entire exposed surface of the magnet module 140, including the space of the module insertion groove 120 remaining after the magnet module 140 is inserted.

Next, as shown in FIG. 7, the applied UV liquid 150 is cured by the action of the heating roller 180, while the flatness of the UV liquid 150 is adjusted.

Next, as shown in FIG. 8, a cell 160 in which a decorative exterior sheet 161 capable of printing or design expression on the layer formed by curing the UV liquid 150 and glass 162 to prevent discoloration are laminated together. Combine. When laminating the cells 160, OCA (Optically Clear Adhesive) or UV (ultraviolet rays) adhesive may be used.

Next, the case plate 110 is cut into case unit plates (not shown) of unit size. In this embodiment, one case plate 110 can be cut into a total of six case unit plates.

Then, a practical magnetic rechargeable mobile phone glass case 100 as shown in FIG. 1 can be formed using the case unit plate.

As described above, the magnetic rechargeable mobile phone glass case 100 according to this embodiment is formed by forming a module insertion groove 120 on a case plate 110, which is a medium-hard PC flat sheet, and then attaching an opaque adhesive tape 130. After inserting the magnet module 140, applying and curing the UV liquid 150, the decorative exterior sheet 161 and the glass 162 are manufactured by laminating the integrated cell 160. There is no need to insert the magnet module 140 and attach a sticker as before. Therefore, not only can the phenomenon of stickers falling off be eliminated, but the magnet module 140 cannot be easily separated from the product. Therefore, it can be a semi-permanent product.

According to the present embodiment, which operates based on the structure described above, it is possible to prevent weakening of magnetic force or a decrease in charging efficiency during wireless charging, as well as eliminating the risk of losing the magnet module 140, especially in the case. In creating a splendid appearance of the case 100, durability can be increased by preventing the case 100 from discoloring yellow due to light.

Figure 14 is a schematic cross-sectional structural diagram of a magnetically rechargeable mobile phone glass case according to another embodiment of the present invention, and Figure 15 is a flowchart of a method of manufacturing the magnetically rechargeable mobile phone glass case of Figure 14.

Referring to these drawings, the magnetically rechargeable mobile phone glass case 200 according to this embodiment is also formed by forming a module insertion groove 220 in the case plate 210, which is a medium-hard PC flat sheet, and then forming an opaque forming material 230. ) is prepared, the magnet module 140 is inserted, the UV liquid 150 is applied and cured, and then the cell 160 in which the decorative exterior sheet 161 and the glass 162 are integrated is treated with OCA (Optically Clear Adhesive). ) or UV (ultraviolet rays) adhesive.

At this time, an uneven surface 222 having a certain roughness is additionally processed at the bottom of the module insertion groove 220. Then, the opaque forming material 230, that is, the opaque glue solution 230, is filled and solidified through this uneven surface 222. At this time, the uneven surface 222 expands the adhesion area of the opaque glue solution 230 so that the opaque glue solution 230 adheres well to the bottom of the module insertion groove 220.

The method of manufacturing this magnetic rechargeable mobile phone glass case 200 includes a case plate preparation step (S110), a module insertion groove processing step (S220a), a groove bottom roughness forming step (S220b), an opaque forming material preparation step (S130), Magnet module insertion step (S140), UV liquid application step (S150), UV liquid curing and flatness adjustment step (S161), case plate cutting step (S170), cell lamination step (S180), and case molding step (S190). It can be included.

In the case of this embodiment, after performing the module insertion groove processing step (S220a), the groove bottom roughness forming step (S220b) is additionally performed before proceeding with the opaque forming material preparation step (S130), which is similar to the above-described embodiment. Different.

That is, the groove bottom roughness forming step (S220b) is a process of additionally processing the uneven surface 222 having a certain roughness at the bottom of the module insertion groove 220 by the action of a rotating tool such as a sand grinder. When the groove bottom roughness forming step (S220b) is performed, an uneven surface 222 having a certain roughness is formed at the bottom of the module insertion groove 220 as described above. By filling and solidifying the opaque forming material 230, that is, the opaque glue solution 230, through the uneven surface 222, the effect is achieved so that the magnet module 140 inserted into the module insertion groove 220 is not visible from the outside. can be provided. The opaque glue solution 230 is an opaque material, and its color can be changed as desired. That is, after making and filling the opaque glue solution 230 with the desired color, it can be solidified and used as the opaque forming material 230.

Even if this embodiment is applied, it is possible to prevent the magnetic force from weakening or charging efficiency to decrease during wireless charging, as well as to eliminate the risk of losing the magnet module 140, and in particular, to create a splendid appearance of the case 100. Durability can be increased by preventing (100) from turning yellow due to light.

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, it should be said that such modifications or variations fall within the scope of the claims of the present invention.
