Multi-stage telescopic mechanism for carrying glass in liquid crystal glass substrate production

Abstract

The invention discloses a multi-stage telescopic mechanism for carrying glass in liquid crystal glass substrate production. The multi-stage telescopic mechanism comprises a first-stage telescopic support arm assembly, an end part fixed connecting arm frame rod is fixedly arranged at one end of the first-stage telescopic support arm assembly, and a second-stage telescopic support arm assembly is telescopically arranged in the first-stage telescopic support arm assembly. A third-stage telescopic support arm assembly is telescopically arranged in the second-stage telescopic support arm assembly.A U-shaped second-stage telescopic support arm frame plate telescopically moves in a U-shaped first-stage telescopic support arm frame plate through left-right reciprocating movement of an inner threaded pipe on a threaded rod, and when the U-shaped second-stage telescopic support arm frame plate telescopically moves in the U-shaped first-stage telescopic support arm frame plate, a plate body of arectangular tertiary telescopic support arm frame plate telescopically moves in the U-shaped second-stage telescopic support arm frame plate through the matching of a rotating gear, a first-stage rack plate and a third-stage rack plate.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal substrate glass production, and in particular relates to a multi-stage telescopic mechanism for transporting glass in the production of liquid crystal glass substrates. Background technique [0002] At present, in the production of liquid crystal glass substrates, during the edging process of the glass, the glass needs to be carried by the handling claws to realize rotation and displacement, so as to complete the edging and chamfering of the four sides. [0003] The existing technology has the following problems: During the whole process of transportation, the upper surface of the product is not allowed to have any contact, so it is necessary to use a telescopic transportation mechanism to extend from the lower surface of the glass substrate, and then lift the substrate glass to achieve the purpose of transfer. However, the current handling claws are limited by space limitations. If the ope...

Problems solved by technology

[0003] The existing technology has the following problems: During the entire process of handling, the upper surface of the product is not allowed to have any contact, so it is necessary to use a telescopic handling mechanism to lower the glass substrate The surface is extended in, and then the substrate glass is lifted to achieve the purpose of transfer. However, the current handling claws are limited by the limited space. If the opening is too large, it will interfere with the peripheral equipment, but if the opening is too small, it will fall. It interferes with the substrate glass, so in order to achieve the purpose of handling, the lower supporting claws cannot be extended too long, resulting in the lower claws being too short when handling the glass and can only hold up a limited range of the edge of the board, so that the middle of the board is suspended too much, resulting in the middle Due to the sinking of gravity, the deflection of the board is too large, which affects the accuracy of positioning, and it is also easy to cause the substrate glass to break due to the gravity in the middle
