Abstract

The utility model discloses a front hardware frame as a main backlight-module spare part for a liquid-crystal display or a liquid-crystal television, in particular to the front hardware frame for a liquid-crystal display panel, which is characterized by comprising two L-shaped material sheets, wherein the two L-shaped material sheets are oppositely welded into a hollow rectangle. By adopting the front hardware frame for the liquid-crystal display panel disclosed by the utility model, a front-frame structure can be formed by a splicing-welding processing method after raw materials are processed through punching, and no large-sheet intermediate waste materials are wasted, so that the purpose of saving the materials is achieved, the utilization ratio of the materials can be improved to 90 percent from 70 percent, and the production cost is saved.

Description

The display panels preceding frame of five metals

Technical field

The utility model relates to a kind of LCD and liquid crystal display television by using module spare and accessory parts backlight, frame before the handware.

Background technology

Along with the expansion in LCD (Liquid Crystal Display is called for short LCD) market, the production and processing amount of module series products backlight increases gradually among the LCD.Frame, backboard are requisite spare parts in the module series products backlight before the handware, and the manufacturer that produces the preceding frame of handware, backboard in the hardware stamping industry significantly increases, and also when the river rises the boat goes up to raw-material demand.Present preceding mount structure during the frame series products, needs to use the whole piece raw material sheet to process before production, center section is peeled off washed out again, about 70% material is wasted with the form of middle waste material, cause utilization rate of raw materials lower, be unfavorable for the economical with materials cost, increased production cost virtually.

The utility model content

Technical problem to be solved in the utility model is to overcome defective of the prior art, provides a kind of display panels with frame before the five metals and laser welding process, improves utilization rate of raw materials, the economical with materials cost.

For solving the problems of the technologies described above, the utility model provides a kind of display panels with frame before the five metals, it is characterized in that comprise two L moulding mixture sheets, two L moulding mixture sheets are to being welded into the rectangle of hollow.

Described L moulding mixture sheet is a standard L moulding mixture sheet: the two ends of L type are straight end;

Or be non-standard L moulding mixture sheet: the two ends of L type all have termination, a right angle.

Described standard L moulding mixture sheet embeds and constitutes a wide L moulding mixture sheet in the described non-standard L moulding mixture sheet.

Described L moulding mixture sheet is in place, L type right angle chamfering.

The outer right-angle side chamfering of termination, described non-standard L moulding mixture sheet right angle.

The described display panels laser welding process of the preceding frame of five metals comprises following steps:

(1) punch process: starting material are struck out L moulding mixture sheet through mould;

(2) laser assembly solder: the square type that L moulding mixture sheet is welded into hollow with the laser assembly solder machine.

L moulding mixture sheet described in the step (1) comprises,

Standard L moulding mixture sheet: the two ends of L type are straight end;

Non-standard L moulding mixture sheet: the two ends of L type all have termination, a right angle.

Described L moulding mixture sheet is in place, L type right angle chamfering, the outer right-angle side chamfering of termination, described non-standard L moulding mixture sheet right angle.

Described standard L moulding mixture sheet, described non-standard L moulding mixture sheet, described chamfering are one time punching molded through mould by starting material.

The beneficial effect that the utility model reached: adopt the display panels of the present utility model preceding frame of five metals, starting material are after punch process, can be welded into the preceding mount structure of hollow with the welding method for processing, change and originally process by the whole piece raw material sheet, center section is peeled off, the situation of waste material reached the purpose of saving material in the middle of waste was large stretch of again, stock utilization can bring up to 90% by 70%, has saved production cost.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model display panels comprises 1 pair of rectangle that is welded into hollow of two L moulding mixture sheets, 1, two L moulding mixture sheet with frame before the five metals.Preferable embodiment is that two L moulding mixture sheet 1 a slices are that the two ends of standard L moulding mixture sheet 2:L type are straight end; Another sheet is that the two ends of non-standard L moulding mixture sheet 3:L type all have termination, a right angle 31.Standard L moulding mixture sheet 2 embeds just and constitutes a wide L moulding mixture sheet in the non-standard L moulding mixture sheet 3, L moulding mixture sheet 1 all has chamfering 4 at place, L type right angle, the outer right-angle side intersection of termination, non-standard L moulding mixture sheet 3 right angle 31 is provided with chamfering 5, abundant reasonable use starting material, chamfering 4,5 is located on the limit of starting material 6, neither need to carry out separately chamfering, saved material again.As shown in Figure 2, on starting material 6, preset standard L moulding mixture sheet 2, non-standard L moulding mixture sheet 3 positions, make its tight arrangement, make full use of starting material, then, starting material 6 are struck out L moulding mixture sheet 1 through mould, as shown in Figure 3, can a punching press next group L moulding mixture sheet, be a slice standard L moulding mixture sheet 2 and the non-standard L moulding mixture of a slice sheet 3, also designing mould as required, array L moulding mixture sheet under the punching press.As shown in Figure 4, the straight end 21 of a slice standard L moulding mixture sheet 2 is relative with 31 positions, termination, right angle of the non-standard L moulding mixture of a slice sheet 3, weld together, just constituted the preceding mount structure of hollow, rectangular.

The above-mentioned display panels preceding frame laser welding process of five metals comprises following steps:

The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
