Description

Maintenance equipment for instrument display system of aviation aircraft

Technical Field

The invention relates to the technical field of display system maintenance equipment, in particular to maintenance equipment for an aviation aircraft instrument display system.

Background

Aviation aircraft's control and state condition all need monitor through display device, need timely maintenance when display device goes wrong, all need unpack display device apart before the maintenance, present display device is mostly LCD, artifical dismantlement is too slow still bumps bad inner screen easily, so dismantle with tearing the screen machine open, the glass apron and the liquid crystal assembly of display are dismantled to the screen machine is torn open to present multi-purpose for laser, the edge at the display is beaten to laser tear open the screen machine open to laser, thereby the glued membrane that will bond between glass apron and the liquid crystal assembly melts separation glass apron and liquid crystal assembly. The existing laser screen dismantling machine has the following problems:

1. when carrying out the LCD location, often adopt anchor clamps to fix LCD's four sides, though can be fixed LCD like this, but can't guarantee that glass apron is parallel with the laser head, it can lead to the laser to shine askew and reflect not parallel, will directly lead to the inner screen to damage when the laser shines on the liquid crystal module, the further damage that has caused the display even directly destroys the display, and when one side was hit to the laser, the molten glued membrane can lead to the distance reduction between this limit glass apron and the liquid crystal module, cause glass apron height on one side low on the whole, also can cause follow-up laser to beat askew and refraction, the damage of indirectly leading to the inner screen aggravates.

2. The laser that now adopts tears screen machine open adopts laser to produce high temperature melting glued membrane in the short time, but stops equipment after melting and take liquid crystal display to tear the screen still very much expend time, probably the glued membrane solidifies once more at normal atmospheric temperature and glues glutinous like this, is unfavorable for dismantling the glass apron, beats laser again and also big to liquid crystal display's damage moreover, and the time of expending has also increased, does not utilize normal maintenance operation.
