Base plate glass lifting and extracting rack arm device

Abstract

The invention discloses a base plate glass lifting and extracting rack arm device. When base plate glass is in contact, lifted and extracted for use, a rack arm mounting footstock cone at the top of a rack arm mounting footstock stand assembly is fixedly connected with an end seat of an external mechanical arm through a mounting hole and a fastening bolt, and a base plate glass contact vacuum suction cup communicates with external vacuum generation equipment through a hose; a lifting driving motor drives a main driving fluted disc to rotate, and the main driving fluted disc drives an auxiliary driving fluted disc to rotate; and through driven rotation of the main driving fluted disc and the auxiliary driving fluted disc, opening and closing stretching and closing contraction movement of a base plate glass lifting and extracting telescopic arm are achieved. In this way, lifting and descending placement during contact, lifting and extracting of the base plate glass is achieved, and secondary stretching, lifting and extracting and secondary contraction movement during contact between the external mechanical arm and the base plate glass are achieved through cooperation of the base plate glass lifting and extracting rack arm device and the external mechanical arm.

Description

technical field [0001] The invention belongs to the technical field of substrate manufacturing, and in particular relates to a frame arm device for lifting and extracting substrate glass. Background technique [0002] With the continuous development and innovation of electronic technology, TFT-LCD (liquid crystal display) is widely used in various electronic products. A basic component of the device, which is a thin glass sheet produced by the float process with an extremely flat surface, the liquid crystal glass substrate is an important part of the liquid crystal flat panel display and has very broad development prospects.

Problems solved by technology

[0003] The existing technology has the following problems: the grinding process in the production process occupies an important position in the entire production process flow, and the quality of grinding depends on the overall grinding equipment and production process flow, but the existing G6 generation substrate grinding equipment and process flow Realize the grinding process of the edge and corner of the glass substrate. In this process, the external mechanical arm and the lifting and extracting device are required to realize the lifting and extraction of the substrate glass. However, when the substrate glass is lifted and extracted, it lacks a flexible contact. , the lifting and extracting arm device that can be freely extended and contacted, and the lifting and extraction is stable and convenient to use cannot meet the current production needs. When the existing substrate glass external robot arm is used alone, it directly contacts the substrate glass, which is easy to cause damage. Lack of An intermediate connecting device, which cannot better meet the current lifting and extraction production needs
