Fig. 1 to 3 show the display back plate of the present invention, which includes a main body 10, a boss 20 and a frame 30.

The main body 10 is embossed such that the main body 10 is provided with a plurality of patterns 11, and the patterns 11 protrude outward from one side and are recessed inward from the other side of the main body 10. The depth of the pattern 11 is 0.1-0.3 mm. Preferably, the depth of the pattern 11 is 0.2 mm. When the depth of the pattern 11 is too small, the effect of enhancing the structural strength cannot be achieved; when the depth is too large, the structural strength of the body 10 is rather weakened. The body 10 has smooth peripheral edges and is not embossed. The thickness of the body 10 is 0.5-1.5 mm. Preferably, the thickness of the body 10 is 1.2 mm.

The boss 20 extends from the body 10. Is the same as the thickness of the body 10. The boss 20 is 0.8mm higher than the body 10. When the glass is used, the glass is attached to the boss 20, and a gap of 0.8mm is formed between the glass and the main body 10 and used for installing the backlight module. The width of the boss 20 is 3 mm.

The frame 30 includes a connecting portion 31, an outer edge 32, a bending portion 33, and an inner edge 34. The connecting portion 31 extends from the boss 20. The outer edge 32 is formed by bending the connecting portion 31. Inner edge 34 is formed by bending outer edge 32. The bending portion 33 is the bending portion between the outer edge 32 and the inner edge 34. The outer edge 32 is perpendicular to the connecting portion 31 and the inner edge 34 is parallel to the outer edge 32. The width of the connecting portion 31 and the bent portion 33 is 2.5 mm. The connecting portion 31 is arc-connected to the outer edge 32. The bent portion 33 is a flat surface.

The main body 10, the boss 20 and the frame 30 are formed by stamping a whole substrate. The boss 20 is located between the main body 10 and the bezel 30. The outer edge 32 is located outermost, away from the body 10. Inner edge 34 is located between outer edge 32 and boss 20.

The utility model discloses still relate to the manufacturing method of above-mentioned display backplate, including following step:

embossing: embossing the base material to form a plurality of patterns 11 with one side concave and one side convex;

blanking: trimming and blanking the embossed base material;

bending: bending the periphery of the base material to form an inner edge 34, wherein the inner edge 34 is vertical to the center of the base material;

leveling: pushing the inner edge 34 flat so that the inner edge 34 is parallel to the center of the substrate;

double bending: bending the substrate again to form outer edge 32, wherein outer edge 32 is parallel to inner edge 34 and outer edge 32 is perpendicular to the center of the substrate;

stamping: bosses 20 are stamped and formed into the substrate adjacent outer edge 32, and bosses 20 are used to engage the glass.

Specifically, the embossing step is as follows: through direct punch forming, the upper die moves downwards, the embossing convex die contacts the base material to extrude the base material into the concave die, and the base material is deformed to form the patterns 11, so that the required embossing shape is achieved. The embossing process with different sizes and specifications can be simultaneously met by one set of die, and if the number of the arranged rows is 20, the stamping can be carried out by only punching 20. When each punching is finished, the material is sent forward by a feeding machine by an embossing center distance (equal feeding).

Specifically, the blanking step is as follows: adopting a contour cutting process, and directly punching and integrally blanking; the upper die moves downwards, the upper die inner stripper and the lower die plate press the base material, the upper die continues to move downwards, the lower die plate and the upper die inner stripper drive the base material to enter the upper die plate, and the middle base material is separated from the outer frame base material, so that the required shape is achieved.

Specifically, the bending step is as follows: integrally forming by direct stamping; the upper die moves downwards, and the upper die is released from the lower die plate to press the base material; the upper die continues to move downwards, the lower die plate and the upper die are internally detached to drive the base material to enter the upper die plate, so that the peripheral base material is deformed, the required edge is bent to form an inner edge 34, and the inner edge 34 is perpendicular to the center of the base material at the moment.

Specifically, the flattening step comprises: integrally forming by direct stamping; the upper die moves downwards, and the upper stripper plate and the lower die plate press the base material; the upper die continues to move downwards, the upper die slotting tool moves downwards to push the side-push flattening sliding blocks to move horizontally towards the middle, the base materials are extruded, the peripheral base materials are deformed, the required flattening effect is achieved, and the inner edges 34 are parallel to the center of the base materials.

Specifically, the double bending step is as follows: integrally forming by direct stamping; the upper die moves downwards, and the upper die is released from the lower die plate to press the base material; the upper die continues to move downwards, the lower die plate and the upper die are separated from each other to drive the base material to enter the upper die plate, so that the peripheral base material is deformed, the required shape is bent, the outer edge 32 is formed, the outer edge 32 is parallel to the inner edge 34, and the outer edge 32 is perpendicular to the center of the base material.

Before the stamping step, a step of trimming is further included, which is to trim the bending part 33 between the outer edge 32 and the inner edge 34 into a plane from an arc shape. Specifically, the step of patting and finishing is as follows: integrally forming by direct stamping; the upper die moves downwards, and the upper inner stripper and the lower die inner stripper press the base material; the upper die continues to move downwards, the lower die inner stripper and the upper die inner stripper drive the base material to enter the upper die plate, and the bent part of the double materials is clamped; the upper die continues to move downwards, the upper die plate, the upper die inner stripper and the lower die inner stripper drive the base material to press downwards, when the base material contacts the lower die shaping block, the base material is extruded (extruded by the force from bottom to top), and finally the bent part 33 is forged and pressed, so that the required product effect and the folding height are formed.

Specifically, the stamping step is as follows: integrally forming by direct stamping; the upper die moves downwards, and the upper stripper plate and the lower die plate press the base material; the upper die continues to move downwards, and the upper die slotting tool moves downwards to push the side push sliding block to clamp the bending edge of the product; and the upper die continues to move downwards, and the convex punching head drives the material to enter the lower die profiling female die, so that the raw material is deformed, and the required shape of the boss 20 is achieved.

Through knurling on the backplate, reinforcing backplate structural strength makes the backplate can be made thin when keeping intensity, lightens weight and volume, reduce cost.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, all according to the equivalent modifications and evolutions of the present invention, which are made to the above embodiments by the essential technology, and all belong to the protection scope of the present invention.
