Method and device for conveying plastic substrate

Abstract

The embodiment of the invention provides a method and a device for conveying a plastic substrate and belongs to the field of industrial control. The method comprises the following steps that when a first optical signal of throwing equipment is in a first threshold range, an inlet unit is switched into a horizontal state, and a plastic substrate is thrown into the inlet unit; when a plurality of second optical signals of the inlet unit are all in a second threshold range, the inlet unit is switched into an inclined state with a preset inclined angle; an outlet electric signal at an outlet of the inlet unit or a middle unit is received, and when the outlet electric signal is in a third threshold range, a next conveying unit of a conveying unit, corresponding to the outlet electric signal, isswitched into the inclined state with a preset inclined angle; and a plurality of third optical signals of a plurality of second preset positions of the outlet unit are received, and when a pluralityof fourth optical signals are all in a fourth threshold range, the outlet unit is switched into the horizontal state. The method and the device can enable the plastic substrate to be successfully conveyed in production equipment, so that the plastic substrate can be avoided from being broken, and the rate of good products is increased.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a method and device for transporting glass substrates. Background technique [0002] Currently, the size of displays tends to be larger, and large-size displays are widely used in home televisions, display devices in public places, and the like. Generally speaking, large-size monitors refer to monitors over 40 inches. The glass substrate is a necessary raw material for the production of the display panel of the display. With the large-scale display, and in order to improve the production efficiency and save the cost of raw materials, the size of the glass substrate put into production is also increasing. Taking the current domestic 8.5-generation line as an example, the size of the glass substrate reaches 2200×2500 (mm). And with the continuous pursuit of production efficiency and raw material costs, the size of the glass substrate will become larger. [0003] However, the gl...

AI Technical Summary

Problems solved by technology

For large-sized glass substrates, due to gravity and the thinness of the glass substrate itself, the central part of the glass substrate will sag, and the resulting problem is that when the glass substrate is transported in the production equipment, the liquid will accumulate in the center. drooping position without smooth flow from the glass substrate

This will lead to poor cleaning effect of the glass substrate, poor circuit patterns on the glass substrate, and fragile glass substrates
