AI Technical Summary

Technical Problem

During the forming process of the glass substrate, the change in the thickness of the glass plate causes unstable pull-down speed of the traction roller, affecting the quality of the finished product.

Method used

A glass traction forming device is designed, including a vertically arranged flow channel, a roller group, a thickness sensor and a controller. By real-time detection of the glass thickness and adjusting the rotation speed and rotation direction of the roller body, the consistency of the glass thickness is maintained.

Benefits of technology

By adjusting the roller body rotation speed and rotation direction in real time, the consistency of glass thickness is maintained, the finished product quality of the glass substrate is improved, and the plate thickness fluctuations are avoided.

Abstract

The invention relates to the technical field of liquid crystal substrate glass manufacturing, in particular to a glass traction forming device which is characterized in that a vertically-arranged runner is arranged in the device, the extending direction of the runner is vertically downward, and the size of the runner is matched with the preset thickness and width of a glass product; the runner is provided with an inlet for leading in overflow glass and an outlet for leading out a cured glass product, the device comprises a roller group consisting of a first roller body and a second roller body, a power assembly for connecting the first roller body and the second roller body, a thickness sensor and a controller, the first roller body and the second roller body are horizontally arranged, the first roller body and the second roller body are arranged in parallel, and the controller is connected with the controller. The first roller body and the second roller body are both located in the device and attached to the two sides of glass flowing through a first position in the flow channel respectively, the thickness sensor is used for detecting the instant thickness of the glass close to the downstream of the first position in real time, and the controller is in communication connection with the thickness sensor and is in control connection with the power assembly.
