In order to make the overall structure have a better appearance.

Figure 8 is a cross-sectional view showing a separation membrane, a first double-sided tape, and a second double-sided tape according to another embodiment of the present invention. Referring to FIG. 8 , in the embodiment, the spacing between the first double-sided tape 530 and the second double-sided tape 540 is gradually increased in the direction D (the spacing L2 is smaller than the spacing L1), so that the user can easily pull the separation film 550. The protruding portion 552 drives the separation film 550 to detach from the first double-sided tape 530 and the second double-sided tape 540 in the direction D. In the present embodiment, the direction D is perpendicular to the longitudinal direction of the separation film 550. In another embodiment, the direction D is parallel to the length direction of the separation membrane 550.

Figure 9 is a partial plan view of an adhesive structure in accordance with another embodiment of the present invention. Figure 10 is a cross-sectional view of the adhesive structure of Figure 9 taken along line C-C. Referring to FIG. 9 and FIG. 10, the separation membrane 650 of the present embodiment includes a plurality of sub-separation membranes 650a to 650c, and the sub-separation membranes 650a to 650c are sequentially arranged adjacent to each other along the width direction of the separation membrane 650. The first double-sided tape 630 is adhered between the first object 610 and the sub-separation films 650a-650c, and the second double-sided tape 640 is adhered between the second object 620 and the sub-separation films 650a-650c. The ends of the sub-separation membranes 650a to 650c protrude from between the first double-sided tape 630 and the second double-sided tape 640 to constitute a projection 652 of the separation membrane 650.

Since the width of the sub-separation membrane 650a, the width of the sub-separation membrane 650b, and the width of the sub-separation membrane 650c are both smaller than the width of the separation membrane 650, it is necessary to resist the separation of the sub-separation membrane 650a, the sub-separation membrane 650b, or the sub-separation membrane 650c. The adhesion is less than the adhesion that must be resisted when pulling the entire separation membrane 650. The user can sequentially pull the sub-separation membranes 650c-650a from between the first object 610 and the second object 620 by the protrusions 652 to make the removal of the separation membrane 650 more labor-saving.

In summary, the embodiment of the present invention has at least one of the following advantages. In the above embodiment of the present invention, the protruding portion of the separation film protrudes from between the first double-sided tape and the second double-sided tape, so that The user facilitates the application of the force to the protruding portion to pull the separation film from between the first object and the second object to release the bonding relationship between the separation film and the first object and the second object. Thereby, the adhesion between the first object and the second object can be maintained, the convenience of disassembly and rework of the adhesive structure can be improved, and the first object and the first object can be reduced due to improper application of the user during disassembly and rework. The probability of damage to two objects.
