Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method of manufacturing a patterned casing. [Prior Art] As consumers' demands for appearance patterns of electronic products increase, the industry continues to innovate in the appearance of electronic products in order to stimulate consumers' desire to purchase. At the same time, in order to meet the requirements of mass production, it is increasingly important to increase the process efficiency of pattern setting and reduce production costs. However, when the pattern is formed on the electronic product casing, when there are many openings in the casing, since the ink pattern is printed in a large amount, when the ink pattern is printed, the cost is not saved on the casing. The corresponding opening of the opening is white. This, after the ink pattern is formed on the casing, leaves excess residue of the ink pattern at the opening in the casing. Moreover, the positional error in the forming process also leaves excess residue of the ink pattern at the opening in the casing. The conventional technique for removing excess residue is by a staff member using a brush to remove excess residue of the ink pattern at the opening in the casing, or by using a sticky tape to remove excess residue. . However, with these methods, the staff can only remove excess residue from the holes in different parts of the casing in sequence, which takes a long time and is inefficient. However, if the manpower is increased in order to increase the overall efficiency of work, it will also increase the cost. Moreover, due to improper application of the staff, damage to the ink pattern that does not need to be removed may also result in product defects, which further increases the cost. 1312723 Therefore, how to design a manufacturing method of a patterned casing that can increase the efficiency of removing excess residue without increasing the cost is one of the important issues at present. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a method of manufacturing a patterned casing which can increase the work efficiency of removing excess residue without increasing the cost. • The edge is that, in order to achieve the above object, a method of manufacturing a patterned casing according to the present invention comprises the steps of: forming a pattern onto a casing, wherein the casing has a plurality of openings, and the pattern covers the Wait at least part of the opening. The pattern covering the openings is removed by a gas ejection device. In summary, a method of fabricating a patterned housing in accordance with the present invention utilizes a gas ejection device to abrade and remove patterns of the openings covering the housing. Compared with the prior art, the present invention utilizes a gas ejection device to simultaneously grind and remove excess residue of holes in different parts of the casing, thereby improving the work efficiency of removing excess residue. This will not only increase the cost of manpower, but also reduce labor costs, further reduce the price of products and increase product competitiveness. [Embodiment] Hereinafter, a method of manufacturing a patterned casing according to a preferred embodiment of the present invention will be described with reference to the related drawings. 1312723 Referring to Figure 1, a method of fabricating a patterned housing in accordance with a preferred embodiment of the present invention includes steps S1 and S2. Among them, the casing is, for example, but not limited to, a casing of various types of products such as a notebook computer, a mobile phone, and a monitor. Referring to FIG. 1 , FIG. 2A to FIG. 2D and FIG. 3 simultaneously, step S1 forms a film 10 having an ink pattern 101 on the surface of the casing 11 , wherein the casing 11 has a plurality of apertures, and the film 10 is Covering at least a portion of the apertures. • The film 10 is first printed with an ink pattern 101 to be formed on the casing 11, and the material of the casing 11 is, for example, a high molecular polymer or a metal. When the material of the casing 11 is a high molecular polymer, the pattern can be formed by In Mold Decoration (IMD) technology, and when the material of the casing 11 is metal, the pattern can be formed by using heat. Pressure transfer. Among them, the in-mold decoration technology can be further divided into In Mold Reprint (IMR) and In Mold Lamination (IML), and the embodiment is described by taking in-mold transfer as an example. ® The following is a brief description of the steps of the above-described transfer, as shown in Figs. 2A to 2D. Referring first to FIG. 2A, first, a film 10 printed with an ink pattern 101 is fed into an injection molding apparatus 2 by a foil-delivered system (not shown), and the film 10 is clamped. It is disposed between an injection mold 21 and a forming mold 22. Next, referring to Fig. 2B, the injection mold 21 and the molding die 22 are pressed against each other, and the film 10 is adsorbed to the injection mold 21 side by vacuum. Next, referring to Fig. 2C, the injection hole 21h of the injection mold 21 is injected into the high molecular weight 1312723 polymer forming the casing 11. Finally, referring to Fig. 2D, after the injection molding of the casing u and the molding die 22 are separated, the ink pattern 1〇1 is transferred from the film 10 to the casing U. According to the above, the difference between the in-mold transfer and the in-mold bonding is that after the film is adhered to the process, the film 10 remains as a protective film on the surface of the casing of the electronic product. The in-mold transfer removes the film 10 after the transfer of the ink pattern 1〇1, leaving only the ink pattern 101 on the casing 11. The hot press transfer used in the case where the body 11 is a metal material transfers the ink pattern 1〇1 on the film 10 to the metal surface of the casing by the heat month b. However, the manner of formation is not the technical focus of the present invention and will not be described herein. Next, referring to FIG. 3, when the housing n is designed with a plurality of apertures, since the film 10 having the ink pattern 101 is printed in a large amount, the ink pattern 101 is printed on the ink, thereby saving The cost will not be left at the corresponding opening of the hole ^. This causes the ink to be formed on the housing U with the 101, and the ink pattern ι〇ι is left at the opening on the housing U. The positional error produced by X' on the forming process also leaves excess residue ρ of the ink pattern ιοί at the opening of the casing. Referring to Figures 1 and 4 simultaneously, the step Μ is to remove the ink pattern covering the apertures by means of the rolling and discharging device 3. The chaotic ejection device 3 is, for example, a sand blasting grinder having a gas compressor 32 connected to each other. After the gas is discharged from the gas discharge/removal machine 32, the gas is discharged by the gas compressor %: -i'. The high-volume 1312723 gas from the gas compressor 32* is mixed with a plurality of granular grinding stones supplied from a grinding sand supply pipe by a pipe 33, and then discharged through the nozzle 31. Since the blasting grinder also has a plurality of different aspects, only the blasting grinder of the above-described aspect is taken as an example. In the above-mentioned sand blasting machine, the abrasive sands s which are sprayed together with the high-pressure gas have high kinetic energy, and the present invention utilizes the abrasive sands to strike the ink pattern 1〇1 at the opening of the casing 11. Excess residue p, l = remove excess residue P to remove. Further, since a plurality of different abrasive sands S are discharged at the same time, the excess residue P of the same opening portion of the casing u can be removed at the same time. In addition, the blasting mill can set an appropriate grinding range by the selection of the bucket: nozzle 31 to increase the work efficiency of removing excess residue. , ^ Note that 'grinding sand s must be selected to not damage the shell π surface, material shell 'The sand s selected for this embodiment is, for example, spherical, and ^ is less than 3 ' and the size of the particle size is between The method of manufacturing a patterned casing according to the present invention utilizes a mouth sand grinder to grind and remove the cover «. Compared with the f-knowledge technology, the present invention _ sandblasting research = ^ grinding to remove excess residue in different parts of the shell, and then: the selection of the nozzle of the sand grinder to set the appropriate grinding range, can be 2 The work efficiency of the excess residue is further improved. Further, the situation in which the ink pattern on the casing is damaged can be avoided by appropriately arranging this m'. By adding more labor costs, it is even more possible to reduce labor costs, 1312723 to further reduce the price of products and increase product competitiveness. The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
