Description

Technical Field

[0001] The utility model relates to the technical field of display processing, in particular to a cover plate positioning and gluing device. Background Art

[0002] At present, in the general assembly process of circular liquid crystal modules, a circular cover plate gluing process is required. Some circular cover plates have a transparent viewing area with a pure circular shape and no logo or text on the exterior. In this case, there is no direction requirement when gluing. Some cover plates have a non-pure circular viewing area, or a logo or text pattern is printed on the front of the cover plate, which creates directionality. The existing alignment method for this type of cover plate is manual pasting alignment, specifically: a silk screen line is set on the back of the cover plate, the cover plate is buckled face down on the operating table, and the double-sided tape is aligned with the silk screen line on the back of the cover plate before pasting. In the above alignment method, in order to see the silk screen line, the worker adopts an inverted buckle method to paste, which is easy to scratch the front of the cover plate. In addition, because the double-sided tape will shake when held in hand, the alignment accuracy is very low, and the double-sided tape is easy to stick outside the outer edge of the cover plate. In addition, in order to facilitate alignment, many silk screen lines must be printed on the back, which is very inconvenient to use. Therefore, a cover plate positioning and gluing device is now provided. Utility Model Content
