Embodiment Construction

[0043] The above objects of the present invention are achieved by adopting aluminum alloy rolled parts and a rotational friction welding method.

[0044] A reinforced frame using aluminum alloy rolled parts for an LCD panel according to the present invention is obtained by rolling four frame parts so as to obtain an L-shaped section, cutting these parts to a suitable length, and then closely connecting these parts to each other into a square shape frame shape. The technical feature is that the corresponding ends of the frame parts are brought into contact, and the four corners are joined by a rotational friction welding method.

[0045]The aluminum alloys used to reinforce the frame according to the invention are wrought aluminum, the most widely acceptable classification of which is as follows: 1000 series are pure aluminum with an aluminum content of at least 99.00 wt %; 2000 series are aluminum copper alloys; 3000 series are aluminum manganese alloys; 4000 series is alumin...

Abstract

The present invention discloses a reinforcement frame for a display panel using aluminum alloy extrusion members and an apparatus and a method for manufacturing the same, wherein, while a number of unitary aluminum alloy extrusion members abut one another, a welding head is used to cause the abutting portions to undergo friction resulting from high-speed rotation so that the members are melted and welded to one another by the resulting frictional heat.

Description

technical field [0001] The present invention relates to a reinforced frame for a display panel using aluminum alloy rolled parts and its manufacturing device and method, wherein a plurality of single The one-piece aluminum alloy rolled parts are adjacent to each other, and the welding head is used to force the adjoining parts to withstand the friction caused by high-speed rotation, so that these parts are fused and welded to each other by the frictional heat generated. Background technique [0002] It is well known in the art that with the improvement of living standards and the substantial improvement of electronic technology, the screen quality of display devices is getting better and better, and the screen size is getting bigger and bigger. A CRT (cathode ray tube), also called a Braun tube, is widely used as a typical display device that is used as a terminal medium (for example, television, computer) to transmit various information, but there are technical limitations,...
