Liquid crystal display module backboard and preparation process thereof

Abstract

The invention provides a liquid crystal display module backboard and a preparation process thereof. The preparation process comprises the following steps: cutting a plate-shaped backboard piece; placing the backboard piece below an upper die and above a lower die; sending a positioning instruction to a positioning device by a controller, so that the distance between the top surface of the positioning device located below the backboard piece and the preset starting point of the backboard piece is 0.1-1 mm; moving the backboard piece until the positioning device detects that the preset starting point position is correct and the distance is within the set threshold range, sending the instruction to the controller, and sending an operation instruction by the controller; enabling the upper die and the lower die to run according to a set track, and enabling the backboard piece to sink downwards in parallel and deform to form a reinforcing part; keeping the preset track consistent with the position of the reinforcing part; and overturning the backboard piece, and using a numerical control turret rib punching and rolling die for punching to form a fixing part. The integrally-formed numerical control turret rib punching and rolling method is adopted, the flexibility is high, the position of the reinforcing rib can be changed at will, and the reinforcing rib can be recovered; and the die is simple in structure and low in processing cost.

Description

technical field [0001] The invention relates to the field of liquid crystal screen preparation, in particular to a liquid crystal screen module backplane and a preparation process thereof. Background technique [0002] The back panel of the LCD screen module is used on the LCD screen, which can block dust and play a fixed role. [0003] When the backplane is applied, the ribs are installed later, and there is no fit between the backplane, and there are many complicated processing procedures, and an external large rear shell is required to cover the ribs to achieve an aesthetic effect, eliminating the need for ribs Costs can be controlled to a greater extent. [0004] The existing technology adopts stamping die forming technology, and utilizes cold stamping die to realize pressure on the material, causing it to deform to form reinforcing ribs. However, this production method involves complex molds and high processing costs. Once the processing is completed and finalized, it...
