Description

The present invention relates to a portable electronic device equipped with a touch screen display having a function as a receiver, and a method for manufacturing the portable electronic device .

  Conventionally, a technique using a double-sided tape for joining a display or the like in a portable electronic device such as a cellular phone has been proposed (for example, see Patent Document 1).

JP 2012-42550 A

  Some portable electronic devices have a touch screen display. Some types of the touch screen display have a function as a receiver (hereinafter, a touch screen display having a function as a receiver is also referred to as a “touch screen display” for short).

  The touch screen display is configured such that the display portion vibrates and generates sound. When the casing of the portable electronic device and the touch screen display are joined with a bond (adhesive), sufficient strength and waterproof performance can be obtained. However, since the display portion is less likely to vibrate, the function as a receiver is impaired.

  In addition, when the casing of the portable electronic device and the touch screen display are joined with a waterproof double-sided adhesive tape, good waterproof performance can be obtained without disturbing the vibration of the display portion. However, when the double-sided adhesive tape is crushed in the pressurizing step after joining and the double-sided adhesive tape is stretched and thinned, the touch screen display is easily broken when an impact is applied to the portable electronic device due to dropping or the like.

  Therefore, there is a model that employs a so-called hybrid structure in which the casing of the portable electronic device and the region excluding the outer peripheral portion of the touch screen display are bonded with a double-sided adhesive tape and the outer peripheral portion of the touch screen display is bonded with a bond. According to this hybrid structure, sufficient strength and waterproof performance can be obtained without disturbing the vibration of the display portion in the touch screen display.

  By the way, when the double-sided adhesive tape is excessively pressurized in the pressurizing step after joining the housing and the touch screen display, the double-sided adhesive tape is liable to be crushed. In the hybrid structure described above, when the double-sided adhesive tape that joins the housing and the touch screen display is crushed, the air (bubbles) contained in the double-sided adhesive tape moves to the bond side, and the air in the bond layer A passage (crack) is formed. For this reason, moisture easily enters the inside of the portable electronic device from the air passage formed in the bond layer, and the waterproof performance is deteriorated. In the pressurizing step after joining, if the pressure for pressurizing the double-sided adhesive tape is weakened, the double-sided adhesive tape becomes difficult to be crushed, but the adhesion between the housing and the touch screen display is lowered. Therefore, there is a need for a portable electronic device that can obtain sufficient strength and waterproof performance without impairing the adhesion between the housing and the touch screen display.

An object of the present invention is to provide a portable electronic device and a method for manufacturing the portable electronic device that can obtain sufficient strength and waterproof performance without impairing the adhesion between the housing and the touch screen display. .

  The portable electronic device according to the present invention includes a housing having a first surface and a second surface opposite to the first surface, an adherend member disposed on the first surface side of the housing, and the housing of the housing. A double-sided adhesive tape disposed between the first surface and the adherend member, and disposed around the double-sided adhesive tape to seal between the first surface of the housing and the adherend member. An adhesive member, wherein the housing communicates the first surface side and the second surface side of the housing, and a part of the double-sided adhesive tape on the second surface side of the housing Has a first opening for exposing the.

  Moreover, the portable electronic device which concerns on this invention WHEREIN: The said 1st opening part of the said housing | casing is good also as a structure provided in the vicinity of the said adhesive member.

  Further, in the portable electronic device according to the present invention, the double-sided adhesive tape has the first opening of the housing and the bonded member at a position overlapping the first opening of the housing in plan view. It is good also as a structure which has the 2nd opening part which connects between.

It is a circular hole communicating between the two.

  The housing side hole 213 provided in the first housing 21 and the tape side hole 251 provided in the double-sided adhesive tape 25 have a size in which a pin 101 provided in the jig 100 described later can be inserted.

  Next, the operation | work which joins the 1st housing | casing 21 and the touch screen display 3 is demonstrated. 5A to 5D are explanatory diagrams of each process of joining the first housing 21 and the touch screen display 3 of the first embodiment. Hereinafter, the first to fifth steps of joining the first housing 21 and the touch screen display 3 will be described with reference to FIGS. 5A to 5D. In addition, the work of the 1st process-the 5th process demonstrated below is implemented by automatic work, such as a manual work by an operator, or an industrial robot.

<First step>
As shown in FIG. 5A, the first housing 21 is placed on the jig 100. The jig 100 is a member used when the first housing 21 and the touch screen display 3 are joined. A plurality of pins 101 protrude from the flat surface 100 a of the jig 100. The pin 101 is a cylindrical protrusion protruding from the flat surface 100 a of the jig 100. The first housing 21 is placed on the jig 100 so that the housing side hole 213 provided in the first housing 21 and the pin 101 of the jig 100 are engaged.

<Second step>
As shown in FIG. 5B, a double-sided adhesive tape 25 is affixed to the back surface side (first housing 21 side) of the touch screen display 3. Further, the bond B is applied around the double-sided adhesive tape 25 attached to the touch screen display 3. The double-sided adhesive tape 25 is applied to the back side of the touch screen display 3 and the bond B is applied to the touch screen display 3, as shown in FIG. 5B. It may be performed with the tape 25 facing the second surface 212 side of the first housing 21, or with the double-sided adhesive tape 25 affixed to the touch screen display 3 facing the upper side of FIG. 5B. You may go.

<Third step>
Subsequently, as shown in FIG. 5B, the touch screen display 3 is placed so that the double-sided adhesive tape 25 and the bond B come into contact with the first surface 211 side of the first housing 21 placed on the jig 100. Join. The bond B applied to the periphery of the double-sided adhesive tape 25 is cured after pressurization in the fourth step to be described later to become the bond layer 26.

<4th process (pressurization process)>
As shown in FIG. 5C, the touch screen display 3 bonded to the first housing 21 is pressed toward the jig 100 by the pressing head 200. The pressure head 200 is a device that can move up and down in a direction (vertical direction) perpendicular to the flat surface 100 a of the jig 100, and can press the touch screen display 3 toward the jig 100 with a predetermined pressure. In the fourth step, the pressure head 200 starts to press the touch screen display 3 joined to the first housing 21 toward the jig 100, and the back surface side of the touch screen display 3 and the pin 101 of the jig 100 are moved. Pressurization is stopped after contact.

  Note that when the touch screen display 3 joined to the first housing 21 starts to be pressed toward the jig 100, the back surface side of the touch screen display 3 and the pin 101 of the jig 100 come into contact with each other. Therefore, the double-sided adhesive tape 25 disposed between the first housing 21 of the touch screen display 3 is pressed further from the position where the back surface side of the touch screen display 3 and the pin 101 of the jig 100 abut. It will not be done. Therefore, when the touch screen display 3 bonded to the first housing 21 is pressed toward the jig 100 by the pressure head 200, the double-sided adhesive tape 25 can be prevented from being pressed more than necessary.

<5th process>
As illustrated in FIG. 5D, the pressure head 200 is raised to separate the first housing 21 from the jig 100.

  Through the first to fifth steps described above, the first housing 21 in which the touch screen display 3 is bonded to the first surface 211 can be manufactured as shown in FIG.

  According to the mobile terminal device 1 of the first embodiment described above, for example, the following effects are exhibited.

  The first housing 21 according to the present embodiment communicates the first surface 211 side and the second surface 212 side, and exposes a part of the double-sided adhesive tape 25 on the second surface 212 side. Is provided. Further, the double-sided adhesive tape 25 of the present embodiment includes a housing-side hole 213 of the first housing 21 and a double-sided adhesive tape 25 at a position overlapping the housing-side hole 213 of the first housing 21 in plan view. A tape side hole 251 is provided to communicate between the two.

  Therefore, as shown in FIG. 5C, when the touch screen display 3 joined to the first housing 21 is pressed toward the jig 100, the double-sided adhesive tape 25 is attached to the back side of the touch screen display 3 and the jig 100. No further pressing is performed from the position where the pin 101 comes into contact. Therefore, the double-sided adhesive tape 25 is crushed in the pressurizing step, and air contained in the double-sided adhesive tape 25 is moved to the bond layer 26 side to suppress the formation of air passages in the layer of the bond layer 26. be able to. According to this, since it becomes difficult for moisture to enter the interior of the portable electronic device 1 from the air passage formed in the layer of the bond layer 26, the waterproof performance can be improved. Moreover, since the double-sided adhesive tape 25 is not easily crushed, the double-sided adhesive tape 25 is prevented from being stretched and thinned. Therefore, it is possible to prevent the touch screen display 3 from being cracked when an impact is applied.

  Moreover, since the touch screen display 3 joined to the first housing 21 can be pressed toward the jig 100 with a predetermined pressure, the adhesion between the first housing 21 and the touch screen display 3 is ensured. Can do.

  Therefore, in the portable terminal device 1 of the present embodiment, sufficient strength and waterproof performance can be obtained without impairing the adhesion between the first housing 21 and the touch screen display 3.

  Further, when the housing side hole 213 and the tape side hole 251 are provided in the vicinity of the bond layer 26 disposed on the outer peripheral portion of the touch screen display 3, the first housing 21 of the first housing 21 is provided after the pressurizing step. Bond B can be easily replenished from the housing side hole 213. Thereby, the waterproof performance between the 1st surface 211 of the 1st housing | casing 21 and the touch screen display 3 can be improved more. Moreover, the waterproof performance between the 1st surface 211 of the 1st housing | casing 21 and the touch screen display 3 is improved further by filling the housing | casing side hole 213 of the 1st housing | casing 21 with the replenished bond B. Can do.

  By the way, the structure which provides a pin in the 1st surface 211 of the 1st housing | casing 21 instead of providing the pin 101 in the jig 100 is also considered. However, when a pin is provided on the first surface 211 of the first housing 21, when an impact is applied to the portable electronic device due to a drop, stress is concentrated between the touch screen display 3 and the pin, and the touch is performed. The screen display 3 may be broken. However, in the mobile terminal device 1 of the present embodiment, the pin 101 of the jig 100 does not remain inside the first casing 21 after the first casing 21 and the touch screen display 3 are joined. It is possible to prevent the occurrence of the above-described problems when pins are provided in the case.

(Second Embodiment)
Next, the portable terminal device 1A in the second embodiment will be described. Since the overall configuration of the mobile terminal device 1A in the second embodiment is the same as that of the first embodiment (FIGS. 1 to 3), differences will be mainly described here. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate. Further, members characteristic of the second embodiment will be described with “A” added to the reference numerals.

  FIG. 6 is a schematic cross-sectional view showing a characteristic part of the mobile terminal device 1A in the second embodiment, and corresponds to the same cross-section along the line AA as FIG. 6 shows the configuration of the housing 2 on the first housing 21A side as in FIG.

  As shown in FIG. 6, in the present embodiment, the bond layer 26 </ b> A is disposed so that a part thereof extends between the double-sided adhesive tape 25 </ b> A and the touch screen display 3. Further, the housing side hole 213 of the first housing 21A and the tape side hole 251 of the double-sided adhesive tape 25 are flat with a part of the bond layer 26A extending between the double-sided adhesive tape 25A and the touch screen display 3. It is provided at an overlapping position in view.

  The configuration shown in FIG. 6 is an embodiment of the case side hole 213 and the tape side hole 251 provided in the vicinity of the bond layer 26, and the case side hole 213 and the tape side hole 251 provided in other regions. Is configured in the same manner as in the first embodiment (FIG. 4).

  Further, in the mobile terminal device 1A in the present embodiment, the operation of joining the first casing 21A and the touch screen display 3 is the same as that in the first embodiment (FIGS. 5A to 5D), and therefore the description by illustration is given. Omitted.

  According to the mobile terminal device 1A of the second embodiment, the same effects as those of the first embodiment described above can be obtained. In particular, in the second embodiment, a part of the bond layer 26A extends between the double-sided adhesive tape 25A and the touch screen display 3, and the housing side hole 213 and the tape side hole 251 are included in the bond layer 26A. It is provided at a position overlapping with a part in plan view. Therefore, after the pressurizing step, the bond B can be replenished to the bond layer 26A more efficiently and quickly from the case side hole 213 of the first case 21A. Therefore, according to 1 A of portable terminal devices of 2nd Embodiment, the waterproof performance between the 1st surface 211 of the 1st housing | casing 21 and the touch screen display 3 can be improved more.

  The present invention is not limited to the first and second embodiments described above, and can be appropriately changed as shown below, and these are also included in the scope of the present invention.

  For example, in the said embodiment, the example which provided the tape side hole 251 in the double-sided adhesive tape 25 (25A) was demonstrated. Not only this but the structure which does not provide the tape side hole part 251 in the double-sided adhesive tape 25 (25A) is good.

  In such a configuration, a part of the double-sided adhesive tape 25 (25A) is pressed by the pin 101 of the jig 100 in the pressing step. However, by appropriately setting the position and the number of pins 101 protruding from the jig 100, the double-sided adhesive tape 25 (25A) can be prevented from being crushed to the extent that no substantial influence is caused. For example, when the pin 101 protruding to the jig 100 is provided at a position away from the bond layer 26 (26A), the air contained in the double-sided adhesive tape 25 is moved to the side of the bond layer 26 due to the collapse of the double-sided adhesive tape 25. It is possible to minimize the formation of air passages in the bond layer 26 as much as possible.

  Accordingly, even when the double-sided adhesive tape 25 (25A) is not provided with the tape side hole portion 251, it is possible to suppress the formation of air passages in the bond layer 26 (26A), and moisture can be bonded to the bond layer. It is possible to make it difficult to enter the inside of the portable electronic device 1 (1A) from the air passage formed in the layer 26 (26A). Moreover, since it is not necessary to provide the tape side hole 251 in the double-sided adhesive tape 25 (25A), it is possible to reduce work man-hours and costs.

  In the above-described embodiment, an example in which the casing side hole 213 provided in the first casing 21 and the tape side hole 251 provided in the double-sided adhesive tape 25 (25A) are circular holes has been described. Not limited to this example, the housing side hole 213 and the tape side hole 251 may be triangular or square holes, or may be polygonal holes. Moreover, in the said embodiment, although the example which used the pin 101 provided in the jig 100 as the column-shaped protrusion was demonstrated, the pin 101 is good also as a protrusion of a triangular prism or a quadratic prism, and also the columnar protrusion by a polygon. As good.

  Further, the shape and size of the hole may be changed according to the position where the housing side hole 213 and the tape side hole 251 are provided. For example, it is conceivable that the size of the hole provided at a position close to the bond layer 26 (26A) is made smaller than the holes provided at other positions (the pin 101 provided in the jig 100 is also the size of the hole). To make it smaller.) In this case, when the double-sided adhesive tape 25 (25A) is crushed in the pressurizing step, the amount of air moving from the double-sided adhesive tape 25 (25A) to the bond layer 26 (26A) can be reduced.

  In the above embodiment, the example in which the mobile electronic device according to the present invention is applied to the mobile terminal device 1 (1A) has been described. The present invention is not limited to this, and the portable electronic device according to the present invention can be applied to all portable electronic devices equipped with a touch screen display having a function as a receiver.
