Embodiment 1

[0023] Embodiment one, see figure 1 with figure 2 Shown, a kind of manufacturing method of TV backplane is characterized in that: by metal surface layer 1, sandwich layer 2, metal bottom layer 3, comprises the following steps: the metal coil is preferably an aluminum coil,

[0024] Step 1: Take the metal coil as the raw material, straighten the metal coil, roll it flat, and use it as a metal strip, clean both sides of the metal strip, and roll the top paint on the top surface of the metal strip, and roll coat the adhesive layer on the bottom surface 20 The edges of the adhesive layer 20 on the bottom surface of the metal strip are continuously rolled with the strip anti-sticking paint 11 along the length direction, and the adhesive layer 20 on the bottom surface of the metal strip is evenly spaced along the width direction and rolled with the horizontal strip anti-sticking paint 12, to form a metal surface layer 1;

[0025] Step 2: Use the metal coil as the raw material, st...

Embodiment 2

[0031] Embodiment two, image 3 As shown, the difference between it and Embodiment 1 is that the sandwich layer 2 is a metal corrugated layer 21, and by coating the adhesive layer 20 on both sides of the metal corrugated layer 21, the adhesive layer 20 is preferably a polymer resin film layer, and the metal corrugated layer The two sides of the layer 21 are respectively bonded to the metal surface layer 1 and the metal bottom layer 3 through the adhesive layer 20 to form a backplane.

Embodiment 3

[0032] Embodiment three, Figure 4 As shown, its difference from Embodiment 1 is that the sandwich layer 2 is a metal honeycomb layer 22, and by coating the adhesive layer 20 on both sides of the metal honeycomb layer 22, the adhesive layer 20 is preferably a polymer resin film layer, and the metal honeycomb layer The two sides of the layer 22 are respectively bonded to the metal surface layer 1 and the metal bottom layer 2 through the adhesive layer 20 to form a backplane.

Abstract

The invention relates to a manufacturing method of a TV set backplane. The method includes the steps of: 1. preparing a metal surface layer: conducting roller coating of finish paint at the top of a metal strip, performing roller coating of an adhesive layer at the bottom surface, carrying out continuous roller coating of strip anti-sticking paint on the adhesive layer along the length direction,and conducting uniformly spaced roller coating of horizontal stripe anti-sticking paint on the adhesive layer along the width direction; 2. preparing a metal base layer: conducting roller coating of finish paint at the bottom surface of a metal strip, and performing roller coating of an adhesive layer at the top surface; 3. rolling the metal surface layer, a sandwich layer and the metal base layerin order into a whole and performing cutting; 4. milling a frame-shaped groove in the inner contour of the anti-sticking paint on the metal base layer; and 5. tearing off the redundant metal base layer and sandwich layer, and bending the exposed metal surface layer stamped towards one side of the metal base layer into a frame. The TV set backplane obtained by the method provided by the inventionis reasonable in design, four sides of the metal surface layer cannot be compounded with the sandwich layer and the metal base layer, thus facilitating cutting of the sandwich layer and the metal baselayer off the four sides of the metal surface layer, the bottom surface around the four sides of the metal surface layer is exposed and can be processed into a frame, so that the frame and the backplane can form an integral structure.

Description

technical field [0001] The invention relates to the technical field of TV backplanes, in particular to a method for manufacturing a TV backplane. Background technique [0002] In traditional TVs, the display panel is clamped and fixed by the front frame or the rear cover. However, with the improvement of living standards, people have higher requirements for display devices, and display devices are developing in the direction of ultra-thin, large-size, and frameless. Existing TV sets are composed of a display panel and a backplane directly fixed. The backplane is composed of a composite board and a frame. The composite board and the frame are produced separately. Display panel assembly. The structure of the backplane is complex and the production process is complicated. Contents of the invention [0003] The object of the present invention is to provide an integrated backplane, a backplane for a display device with a simple structure and easy production. [0004] The pur...
