Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] figure 1 A method for producing a liquid crystal display frame according to an embodiment of the present invention is schematically shown. Such as figure 1 As shown, the liquid crystal display frame production method of the present invention comprises the following steps: stamping out the front frame substrate from the material roll;

[0032] Bending the front frame substrate;

[0033] Punch the window hole on the bent front frame substrate to obtain scrap substrate and front frame;

[0034] Stamping the back panel flange from the roll and then bending the back panel flange;

[0035] The waste substrate is fixedly connected with the folded edge of the bent backplane to form the backplane.

[0036] Such as Figure 2 to Figure 4 As shown, a punching machine is used to punch out a front frame substrate 101 from a roll, and t...

Abstract

The invention relates to a production method of a liquid crystal display frame. The method comprises the following steps of: stamping a front frame substrate from a material coil, then bending the front frame substrate and stamping a window hole on the bent front frame substrate to obtain a waste substrate and a front frame; then stamping a back plate flanging from the material coil and bending the back plate flanging; and finally, fixedly connecting the waste substrate with the bent back plate flanging to form a back plate. The middle waste substrate generated in the production process of the front frame is used for producing a back plate substrate, so that the material use cost is greatly reduced and the raw materials are saved.

Description

technical field [0001] The invention relates to the field of liquid crystal display frames, in particular to a method for producing a liquid crystal display frame. Background technique [0002] In the existing production method of the liquid crystal display frame, the front frame is cut and punched, and then the rough edge and the font are pressed out, and then the convex hull is punched and the four sides are bent, and then the window hole waste is cut off on the substrate, and finally the front frame is formed. In the production of the backboard, it is necessary to retake the material from the roll and then punch holes, punch out convex hulls and ribs, and then bend them into shape. Due to the frame structure of the front frame, a large number of raw materials are cut off during the process of obtaining materials for the front frame, which increases a lot of cost. In the production process of the backplane, because the material is taken together with the backplane substra...
