Device for measuring length of jackscrew of traction roller for substrate glass

Abstract

The invention discloses a device for measuring length of a jackscrew of a traction roller for substrate glass. The device comprises a retaining wall and a rotating base installed on the outer side face of the retaining wall, wherein an L-shaped connecting piece is rotatably installed on the rotating base, a limiting clamping piece is installed at the outer end of the L-shaped connecting piece, a balance weight limiting piece is installed at one end of the L-shaped connecting piece, and the other end of the L-shaped limiting piece is provided with a measuring mechanism and an adjusting screw rod; balancing weights are evenly distributed at the inner ends of the balancing weight limiting piece, a propelling connecting rod is installed below the rotating base, and the outer end of the propelling connecting rod is connected with the L-shaped connecting piece through a hinge base. Through scientific and reasonable structural design, accurate measurement can be carried out when the traction roller is adjusted, the running position of the traction roller is accurately judged, stable production is facilitated, the structure is simple, operation is convenient, and the traction roller adjusting device is worthy of application and popularization.

Description

Technical field [0001] The invention belongs to the field of glass substrates, and more particularly to a substrate glass traction roller top wire length measuring device. Background technique [0002] During the manufacturing process of the TFT-LCD liquid crystal glass substrate, the traction roller is required to operate at a high speed, a stable state in a clamping force, a non-misleashed blank, and the like to ensure that the glass plate is stable in the lower process during the pull-down process, thereby reducing defects The occurrence of ensuring normal production. [0003] At present, the TFT-LCD liquid crystal glass substrate uses multi-roller clamping during annealed drop-down process, which provides a stable clamping in glass drop, and the longitudinal adjustment of the traction roller is very important to the longitude position of the traction roller in the annealing furnace. . At present, the length of the long adjustment of the traction roller can only be measured by...

Problems solved by technology

At present, the length adjustment of the top wire of the traction roller can only be measured manually. Due to the incorrect position of the measuring ruler during manual measurement, the accuracy of the measurement results is open to question.
