the utility model provides a buffering copper foil sticky tape under LCD screen, includes first copper foil layer, sets up in first copper foil layer below and the rubber buffer layer who is connected with first copper foil layer viscose, sets up in rubber buffer layer below and the second copper foil layer of being connected with rubber buffer layer viscose and sets up the viscose layer in second copper foil layer below, the viscose layer is used for bonding LCD screen and second copper foil layer, the thickness on second copper foil layer is greater than the thickness on first copper foil layer.

Further, the method comprises the following steps: the thickness of the first copper foil layer is 18-35um.

Further, the method comprises the following steps: the thickness of the rubber buffer layer is 50-200um.

Further, the method comprises the following steps: the thickness of the second copper foil layer is 25-60um.

Further, the method comprises the following steps: the thickness of viscose layer is 10-50um.

Utility model's beneficial effect: the second copper foil layer, the rubber buffer layer and the first copper foil layer are sequentially arranged below the liquid crystal screen, so that point-surface buffering is formed when the liquid crystal screen is impacted, and the liquid crystal screen is effectively protected.

Drawings

Fig. 1 is a schematic view of a buffer copper foil tape under a liquid crystal display panel according to an embodiment of the present disclosure.

Labeled as: 1. a first copper foil layer; 2. a rubber buffer layer; 3. a second copper foil layer; 4. an adhesive layer; 5. a liquid crystal panel.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in the figure, the embodiment of this application provides a cushion copper foil sticky tape under LCD screen 5, including first copper foil layer 1, set up in 1 below of first copper foil layer and with 1 viscose connection's of first copper foil layer rubber buffer layer 2, set up in 2 below of rubber buffer layer and with 2 viscose connection's of rubber buffer layer second copper foil layer 3 and set up viscose layer 4 in 3 below of second copper foil layer, viscose layer 4 is used for bonding LCD screen 5 and second copper foil layer 3, the thickness of second copper foil layer 3 is greater than the thickness of first copper foil layer 1.

The manufacturing process comprises the following steps: firstly, arranging a buffer glue layer on the surface of a first copper foil layer 1 and conforming to a second copper foil layer 3 to form a copper foil rubber composite film; secondly, arranging an adhesive layer 4 on the surface of the copper foil rubber composite film; and thirdly, attaching the copper foil rubber composite film to the liquid crystal screen 5 through the adhesive layer 4.

In the design, the second copper foil layer 3, the rubber buffer layer 2 and the first copper foil layer 1 are sequentially arranged below the liquid crystal screen 5, so that point-surface buffering is formed when the liquid crystal screen 5 is impacted, and the liquid crystal screen 5 is effectively protected.

Specifically, the method comprises the following steps: the thickness of the first copper foil layer 1 is 18-35um.

In the above design, the thickness of the first copper foil layer 1 is obtained when the first copper foil releases energy while ensuring the thinning of the whole product, and the energy can be released based on the first copper foil layer 1 in the range of 18-35um.

Specifically, the method comprises the following steps: the thickness of the rubber buffer layer 2 is 50-200um.

In the above design, the thickness of the rubber buffer layer 2 is formed by combining the rubber expansion coefficient and the impact energy.

Specifically, the method comprises the following steps: the thickness of the second copper foil layer 3 is 25-60um.

In the above design, the second copper foil layer 3 mainly plays a role of energy resistance, and resists the energy transmitted and filtered by the rubber buffer layer 2, and the thickness of the second copper foil layer 3 is obtained by combining the hardness, the adhesive force and the heat conduction effect thereof, and the requirement of thinning the product is met.

Specifically, the method comprises the following steps: the thickness of the adhesive layer 4 is 10-50um.

In the above design, the thickness of the adhesive layer 4 is determined comprehensively according to the adhesive force required by the combined weight of the first copper foil layer 1, the rubber buffer layer 2 and the second copper foil layer 3, the adhesive coefficient of the adhesive layer 4 and the adhesive coefficient of the liquid crystal screen 5.

In the following detailed description, it is to be understood that the above-described embodiments are merely exemplary of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
