Background
Generally, in the backlight module assembling process, the shading adhesive tape can be used for coating, and when the shading adhesive tape is used for feeding, the shading adhesive tape can be attached to a release film for convenience of transportation and production line operation. When the attached of actual shading sticky tape, generally divide into two sections with convenient attached with the parting film, tear earlier first half from the type membrane, accomplish afterwards, tear the lower half again from the type membrane, produce the line and for factors such as production efficiency, time cost, productivity, the operation personnel generally all move very fast, if meet the shading sticky tape of special shape, factor such as the shading sticky tape is ultra-thin is considered again, when the lower half that tears off like this from the type membrane, lead to shading sticky tape bight to split easily.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a backlight unit can effectively avoid tearing the shading sticky tape that leads to from the type membrane and damage.
The utility model provides a backlight module, which comprises a first release film, a second release film and a shading adhesive tape; the shading adhesive tape is adhered to the first release film and the second release film; a first cutting line is arranged between the first release film and the second release film, and the first release film can be torn from the shading adhesive tape along the first cutting line; the second is equipped with the second cut-off line respectively from type membrane both ends, and the second cut-off line is crossing with first cut-off line, the second can be followed the second cut-off line from type membrane and torn from the shading sticky tape.
Preferably, the first cutting line comprises a first straight line segment, a second straight line segment connected with the first straight line segment and vertically downward, a third straight line segment connected with the second straight line segment and vertically rightward, a fourth straight line segment connected with the third straight line segment and vertically upward, and a fifth straight line segment connected with the fourth straight line segment and vertically rightward.
Preferably, the two second cutting lines are arc-shaped curves, one second cutting line is bent and extended from the intersection point of the second straight line segment and the third straight line segment to the second release film side, and the other second cutting line is bent and extended from the intersection point of the third straight line segment and the fourth straight line segment to the second release film side.
The utility model discloses a first cut-off line that sets up between the type membrane is released from type membrane and second in first, and the second sets up the second cut-off line respectively from type membrane both ends, shifts the second from the impetus when type membrane tears, can effectively avoid tearing the second and damage from the shading sticky tape that the type membrane leads to.
Drawings
Fig. 1 is a schematic view of a first cut-off line structure of the present invention;
fig. 2 is a schematic view of the backlight module of the present invention.
Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
For the sake of simplicity, only the parts relevant to the present invention are schematically shown in the drawings, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".
The utility model provides a backlight module, as shown in fig. 1 and fig. 2, comprising a first release film 10, a second release film 20 and a shading adhesive tape 30; the shading adhesive tape 30 is adhered to the first release film 10 and the second release film 20; a first cutting line is arranged between the first release film 10 and the second release film 20, and the first release film 10 can be torn from the shading tape 30 along the first cutting line; the two ends of the second release film 20 are respectively provided with a second cut line 50, the second cut line 50 is intersected with the first cut line, and the second release film 20 can be torn from the shading adhesive tape 30 along the second cut line 20.
The first cutting line includes a first straight line segment 41, a second straight line segment 42 connected to the first straight line segment 41 and vertically downward, a third straight line segment 43 connected to the second straight line segment 42 and vertically rightward, a fourth straight line segment 44 connected to the third straight line segment 43 and vertically upward, and a fifth straight line segment 45 connected to the fourth straight line segment 44 and vertically rightward.
The two second cutting lines 50 are arc-shaped curves, one second cutting line 50 is bent and extended from the intersection point of the second straight line segment 42 and the third straight line segment 43 to the second release film 20 side, and the other second cutting line 50 is bent and extended from the intersection point of the third straight line segment 43 and the fourth straight line segment 44 to the second release film 20 side.
When the actual light-shielding tape is attached, the first release film 10 is firstly torn from the light-shielding tape 30 along the first cutting line, then the second release film 20 is torn from the light-shielding tape 30 along the second cutting line 50, and when the second release film 20 is torn, the tearing point of the second release film 20 and the light-shielding tape 30 is shifted from the point a to the point b in the figure, so that the risk that the light-shielding tape 30 cracks at the point a is avoided.
