Description

  The present invention relates to a terminal device manufacturing apparatus in which a display member is bonded to a housing by an adhesive member, and a method of manufacturing the terminal device.

  In a terminal device typified by a mobile phone, a technique is known in which a display member is bonded to a housing with a double-sided tape in order to ensure the waterproof function of the device (see Patent Document 1). In this technique, the display member is generally bonded to the housing using a dedicated jig.

  FIG. 5 is a diagram for explaining a terminal device and its manufacturing apparatus related to the present invention. Fig.5 (a) is a perspective view which shows the principal part structure of the terminal device 200 relevant to this invention. FIG.5 (b) is sectional drawing which shows the structure of the manufacturing apparatus 100 relevant to this invention. FIG. 5B corresponds to a cross-sectional view along the cutting line AA shown in FIG.

  As shown in FIG. 5B, the terminal device 200 includes a display member 201, a double-sided tape 202, and a housing 203. The manufacturing apparatus 100 includes a pressing jig 101 and a pressing jig 102. When the display member 201 and the casing 203 are pressed while being sandwiched between the pressing jig 101 and the pressing jig 102, the double-sided tape 202 is crushed and the display member 201 adheres to the casing 203.

JP 2008-109495 A

  In the manufacturing apparatus 100 shown in FIG. 5B, the surface of the pressing jig 101 that contacts the display member 201 and the surface of the pressing jig 102 that contacts the housing 203 are both flat surfaces. Therefore, there is a possibility that the double-sided tape 11 is bonded to the casing 203 from both ends thereof toward the center due to the warp of the casing 12 accompanying the pressing of the pushing jig 101. When the display member 201 adheres to the housing 203 through such an adhesion process, air S (see the hatched portion shown in FIG. 6A) gathers at the center of the double-sided tape 11 as shown in FIG. Is likely to be. Since the air S has no escape space, it may remain between the double-sided tape 202 and the housing 203 after the pushing jigs 101 and 102 are removed from the terminal device 200 (see FIG. 6B). In this case, there is a high possibility that many defective products are generated due to poor adhesion of the double-sided tape 202. In order to make this defective product a non-defective product, it is necessary to disassemble the terminal device 200 and reassemble it, which takes a lot of work time.

(First embodiment)
FIG. 1 is a perspective view showing the configuration of the manufacturing apparatus according to the first embodiment of the present invention. 2 is a cross-sectional view of the manufacturing apparatus shown in FIG. The manufacturing apparatus 1 of this embodiment is an apparatus for manufacturing the terminal device 10.

  First, the configuration of the terminal device 10 will be described. The terminal device 10 includes a flat display member 11 on which an image is displayed on one side, a frame-like adhesive member 12 attached to the other surface of the display member 11, and an adhesive surface 13 a in contact with the adhesive member 12. And a housing 13. In the present embodiment, the terminal device 10 is a mobile phone, the display member 11 is configured to display an image using a liquid crystal technology or an organic electroluminescence technology, and the adhesive member 12 is a double-sided tape or an adhesive.

  Next, the configuration of the manufacturing apparatus 1 will be described. The manufacturing apparatus 1 includes a pair of pushing jigs 2 and 3. The pressing jig 2 is formed in a rectangular frame shape. A curved surface 2 a that is curved in a convex shape is formed on each side of the pressing jig 2. On the other hand, a curved surface 3a that is curved in a convex shape is also formed on one surface of the pushing jig 3. The material of the pair of pushing jigs 2 and 3 is an elastic member such as rubber, for example.

  Next, the process of bonding the display member 11 to the housing 13 using the manufacturing apparatus 1 described above will be described. As shown in FIG. 2, the top of the curved surface 2 a of the pressing jig 2 faces the top of the curved surface 3 a of the pressing jig 3 across the center of the side (short side) of the adhesive member 12. The display member 11 and the housing 13 are sandwiched and pressed. Then, the curved surfaces 2a and 3a are deformed so that the range in which the adhesive member 12 is pressed from the central portion of the side portion toward the both end portions of the side portion is widened between the adhesive surface 13a and the display member 11. Thereby, since it becomes easy for air to escape outside, air becomes difficult to remain between the adhesion member 12 and the housing 13. As a result, the manufacturing apparatus 1 of the present embodiment can reduce adhesion failure when the display member 11 is bonded to the housing 13 as compared with the manufacturing apparatus 100 described above.

  Further, in the present embodiment, the pressing jigs 2 and 3 are made of rubber, so that the pressing jigs 2 and 3 can reliably and evenly bond the adhesive member 12 to the entire bonding surface 13a during pressurization. Become.

  In the present invention, the shape of the pushing jig 3 is not limited to the kamaboko shape in which the curved surface 3a is in contact with the entire housing 13 as shown in FIG. For example, as shown in FIG. 3, the curved surface 3 a of the pressing jig 3 is formed in a frame shape corresponding to each side (long side and short side) of the adhesive member 12 (4 The shape may be such that two semi-cylindrical bodies are connected in a rectangular shape). Even when the curved surface 3a has such a shape, it is possible to widen the pressing range from the central part of the side part of the adhesive member 12 toward both end parts of the side part during pressurization.

(Second Embodiment)
FIG. 4 is a cross-sectional view of the manufacturing apparatus 1a of the present embodiment. Hereinafter, the same reference numerals are given to the same configurations as those of the manufacturing apparatus 1 of the first embodiment described above, and detailed description thereof is omitted.

  The manufacturing apparatus 1a of the present embodiment includes a pressing jig 2 and a pressing jig 4. A flat surface 4 a is formed on the pressing jig 4. When the display member 11 is bonded to the housing 13 using the manufacturing apparatus 1a, first, the top of the curved surface 2a of the pressing jig 2 is pressed and pressed across the center of the side (short side) of the bonding member 12. The display member 11 and the housing 13 are sandwiched and pressed while facing the flat surface 4 a of the tool 4. Then, similarly to the first embodiment, the adhesive member 12 is curved between the adhesive surface 13a and the display member 11 so that a range in which the adhesive member 12 is pressed from the central portion of the side portion toward both end portions of the side portion is widened. The surface 2a is deformed. Therefore, the air entrained at the time of pressurization easily escapes to the outside, so that the air hardly remains between the adhesive member 12 and the housing 13. As a result, the manufacturing apparatus 1a according to the present embodiment can reduce adhesion failure when the display member is bonded to the housing, as compared with the manufacturing apparatus 100 described above.

  In this embodiment, the push jig 2 has a curved surface 2a and the push jig 4 has a flat surface 4a. However, the push jig 2 has a flat surface and the push jig 4 is curved. The structure provided with a surface may be sufficient. Even in such a configuration, it is possible to widen the pressing range from the center of the side of the adhesive member 12 toward both ends of the side during pressurization.
