1. Field of the Invention
The present invention relates to a back cover manufacturing method, and more specifically, to a back cover manufacturing method by bending a striped sheet to form a back cover.
2. Description of the Prior Art
In general, a conventional backlight module has a back cover and disposal of the back cover is as shown in
In the prior art, forming of the back cover 20 is performed by a material removing process. Please refer to
An objective of the present invention is to provide a back cover manufacturing method by bending a striped sheet to form a back cover for solving the aforesaid problem.
The present invention provides a back cover manufacturing method. The back cover manufacturing method includes providing a striped sheet, bending the striped sheet along a long side of the striped sheet to form a hem, cutting the striped sheet to make the striped sheet have at least one concave portion formed thereon for correspondingly forming a plurality of striped sections, and bending the plurality of striped sections to form a back cover. The back cover is used for being disposed in a backlight module to hold at least one optical component of the backlight module.
Compared with the prior art, the present invention utilizes the design in which a striped sheet is bent to form a back cover for holding backlight components in a backlight module, to replace the aforesaid material removing design. In such a manner, since the back cover manufacturing method provided by the present invention can be completed without additionally performing a material removing process, the present invention can efficiently solve the material waste problem mentioned in the prior art, so as to decrease the material cost of the backlight module in manufacturing the back cover.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
Please refer to
More detailed description for the forming process of the back cover 110 is provided as follows. Please refer to
Step 400: Provide a striped sheet 112;
Step 402: Bend the striped sheet 112 along a long side 111 of the striped sheet 112 to form a hem 113;
Step 404: Cut the striped sheet 112 to make the striped sheet 112 have at least one concave portion 114 formed thereon for correspondingly forming a plurality of striped sections 115 on the striped sheet 112;
Step 406: Bend the plurality of striped sections 115 to form the back cover 110.
The aforesaid steps are described in details herein. Please refer to
Subsequently, the striped sheet 112 is cut to have at least one concave portion 114 formed thereon by a conventional cutting process, so as to correspondingly form the plurality of striped sections 115 on the striped sheet 112 (Step 404). To be more specific, in this embodiment, the striped sheet 112 is preferably cut to form four concave portions 114 as shown in
Finally, in Step 406, the striped sections 115 on the striped sheet 112 as shown in
It should be mentioned that forming of the back cover is not limited to the aforesaid embodiment and varies with number of the concaves portions and the striped sections on the striped sheet. For example, according the aforesaid steps, the striped sheet 112 is cut to form three concave portions 114 thereon for correspondingly forming four striped sections 115, and then the four striped sections 115 are bent to make any two adjacent striped sections 115 perpendicular to each other, so as to form a back cover 110′ in a rectangular shape as shown in
Compared with the prior art, the present invention utilizes the design in which a striped sheet is bent to form a back cover for holding backlight components in a backlight module, to replace the aforesaid material removing design. In such a manner, since the back cover manufacturing method provided by the present invention can be completed without additionally performing a material removing process, the present invention can efficiently solve the material waste problem mentioned in the prior art, so as to decrease the material cost of the backlight module in manufacturing the back cover.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
