Example Embodiment

[0053] In order to make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clear, the technical solutions of the present invention will be further described below with reference to the drawings and specific implementations.

[0054] This embodiment provides a positioning device, which can be used, for example, to position the rubbing cloth in the applicator, so as to align the alignment film, so that the alignment film has liquid crystal alignment capability. In this embodiment, the positioning of the friction cloth is taken as an example. The friction cloth is the part to be positioned, and the friction roller is the positioning reference part of the friction cloth.

[0055] Such as Figure 4 As shown, the positioning device includes a first positioning component 410 and a second positioning component 420. The first positioning component 410 is installed on the friction roller 100, and the first position...

Abstract

The invention discloses a positioning device and a positioning method, and relates to the technical field of positioning and measuring devices. The positioning device comprises a vertical reflecting plate, a supporting rod and a distance measuring mechanism; the vertical reflecting plate is arranged on a positioning reference part and is parallel to the positioning reference part; one end of the supporting rod is rotatably connected with a workbench, the other end of the supporting rod is provided with a positioning block, and the end face of the side, far away from the supporting rod, of thepositioning block is perpendicular to the length direction of the supporting rod; and the distance measuring mechanism is arranged on the supporting rod and arranged to be opposite to the vertical reflecting plate, and the distance measuring mechanism is configured to detect the distances between at least two points on the supporting rod and the vertical reflecting plate. According to the positioning device, when the distances between the at least two points on the supporting rod and the vertical reflecting plate are equal, the supporting rod is parallel to the positioning reference part; andthen the edge of a to-be-positioned workpiece is arranged along the end face of the side, far away from the supporting rod, of the positioning block, therefore, the edge of the to-be-positioned workpiece can be perpendicular to the positioning reference part, skewing of the to-be-positioned workpiece is avoided, and the position precision of the to-be-positioned workpiece is guaranteed.

Description

technical field [0001] The invention relates to the technical field of positioning and measuring devices, in particular to a positioning device and a positioning method. Background technique [0002] In a liquid crystal display (Liquid Crystal Display, LCD) manufacturing process, in order to align the liquid crystals, it is necessary to align the cured alignment film. At present, a relatively mature alignment method is to roll a rubbing roller with a rubbing cloth, and the rubbing cloth rubs the alignment film, so that the alignment film has the ability to align liquid crystals. [0003] Such as figure 1 As shown, before alignment, according to the size of the friction roller 100', select a suitable friction cloth 300' and place it on the workbench 200', press the friction roller 100' to one side of the friction cloth 300', and the friction roller 100' rolls The rubbing cloth 300' may be adhered to the surface of the roller. Since the alignment direction of the alignment ...
