Abstract

The invention provides an alignment ultraviolet meter. The meter includes a chamber, a heating stage, a heat-conducting plate, and a vacuum adsorption mechanism; the vacuum adsorption mechanism includes an adsorption unit, a vacuuming unit and a driving unit; When the meter is used, the driving unit drives the adsorption unit into the chamber, adsorption is performed on a display panel from the upper side of the display panel, thereby picking up or putting down the display panel from the heat-conducting plate, through arrangement of the vacuum adsorption mechanism, the meter performs pick-and-place of the display panel on the heat-conducting plate, thereby eliminating the need to dispose a lifting column structure in the heating stage, an opening hole is avoided to be disposed corresponding to a lifting column on the heat-conducting plate, so that a product layout is flexible, the heat-conducting plate also does not need to be specially customized according to different products, so that when ultraviolet alignment is performed on the different products, switching of a production line is not required, the problems that the switching the heat-conducting plate in an existing alignmentultraviolet meter affects production power, deformation of the heat-conducting plate affects yield rate, design of the lifting column limits layouts of subsequent new products, and the like are solved, and the production power can be greatly improved.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to an alignment ultraviolet irradiation machine. Background technique

[0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight type liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Usually, a liquid crystal display panel consists of a color filter (Color Filter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) substrate, a liquid crystal (Liquid Crystal, LC) sandwiched between the color filter substrate and the TFT substrate, and a sealant (Sealant) composition. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal mole...
