Abstract

The invention provides a manufacture method of a liquid crystal display front frame. Firstly, raw materials are cut into rectangular material pieces, the four rectangular material pieces are connected to form a rectangular frame, four connection corner portions of the rectangular frame are polished, then the rectangular frame after being polished is placed into a die for stamping so that the edges of the rectangular frame are bent inwards, the bending angle is 0-180 degrees, and finally, the outer surface of the rectangular frame is polished. Compared with the prior art, the manufacture method can improve a utilization rate of the raw materials greatly and protect a liquid crystal display and the front frame from being corroded by water and acid-base materials. In addition, according to the manufacture method, a cutting procedure is simplified, the utilization rate of the raw materials is improved, a rejection rate is reduced, and cost is saved.

Description

A kind of method for making of front frame of liquid crystal display

Technical field

The present invention relates to the method for making of liquid crystal display accessory, especially relate to a kind of method for making of front frame of liquid crystal display.

Background technology

LCD TV likes and welcomes with its frivolous user's of being subject to, and its accessory such as front frame, backboard etc. are requisite assemblies in lcd products.At present, during the front frame of liquid crystal display is produced, typically use the whole piece starting material and carry out cutting processing, and the center section that is cut normally falls with the formal layout of middle waste material, cause raw-material utilization factor very low, in case and the fracture in the cutting punching course, just directly products waste, increased production cost.

Summary of the invention

In order to solve deficiency of the prior art, the invention provides a kind of method for making of front frame of liquid crystal display, improved raw-material utilization factor, reduced production cost.

Technical scheme of the present invention is as follows:

A kind of method for making of front frame of liquid crystal display comprises the steps:

(a) raw material is cut into the rectangle tablet;

(b) 4 rectangle tablets are connected into rectangle frame;

(c) 4 connection rotation angle positions of rectangle frame are polished;

(d) rectangle frame after polishing is put into mould and is carried out punching press, and the edge of rectangle frame is bent inwards, and bending angle is 0~180 degree.

(e) outside surface with rectangle frame carries out polishing.

Further, the surface of described rectangle frame is provided with protective seam.

Further, described raw material is metal or plastics.

Compared with prior art; the invention has the beneficial effects as follows; due to the method that has adopted the raw material cutting to connect again; can greatly improve the utilization factor of raw material, owing to being provided with protective seam, can better protect liquid crystal display and front frame to avoid the corrosion of moisture and acid-base material; this method has been simplified cutting process; improve the utilization factor of raw material, reduced rejection rate, saved cost.

Embodiment

below the present invention is described further: first raw material is delivered to cutting machine, length and width according to liquid crystal display, raw material is cut into the rectangle tablet that is fit to liquid crystal display length and width, 4 rectangle tablets are connected into rectangle frame with welding or bonding method, the size of rectangle frame and the in the same size of liquid crystal display, the rotation angle position that connects is polished with sander, make the surfacing of rectangle frame, rectangle frame after polishing is put into diel carry out punching press, the edge of rectangle frame is bent inwards, bending angle is 0~180 degree, the outside surface of rectangle frame after punching press is carried out polishing with buffing machine, with protective paint on the surface brush of the rectangle frame after polishing.

Draw according to experiment, when the bending angle at the edge of rectangle frame is 80~100 when spending, best results of the present invention.

Need to prove above is preferred embodiment of the present invention, and is not to limit the scope of protection of present invention, and every being equal to of doing on the basis of the above replaces or conversion, all belongs to the scope of protection of the invention.
