Control method and system for glass coating export pan division

Abstract

The invention discloses a glass coating outlet pot-separating control method and a glass coating outlet pot-separating control system. The method is used for pot-separating control in an outlet transition chamber for glass coated with film in a vacuum sputtering chamber, and comprises the following steps: S1, acquiring ith glass data of the glass in the ith pot, wherein the ith glass data comprises a measured length of the glass in the ith pot before entering the vacuum sputtering chamber, and i is larger than or equal to 1; S2, uploading the ith glass data to a background server; S3, taking out the ith glass data from the background server, and using the measured length of the ith glass data as a length standard, and performing outlet pot-separating on the glass in the ith pot in the outlet transition chamber; when the glass in the ith pot enters the vacuum sputtering chamber, i being plus with 1, executing the steps S1-S3 for the glass in the (i+1)th pot and performing the pot-separating control. According to the glass coating outlet pot-separating control method and the system disclosed by the invention, the glass in the ith pot can be divided into another pot in the process of being transferred from the vacuum sputtering chamber to the outlet transition chamber, so that the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of glass sputtering coating, in particular to a method and system for controlling glass coating outlet split pots. Background technique [0002] The glass sputtering coating is completed in a vacuum chamber, the glass moves at a constant speed in the vacuum sputtering chamber, and the sputtering chamber is operated at a high speed after being divided into pots. In the production process of vacuum sputtering glass coating, the glass vacuum sputtering chamber splitting process has the greatest impact on production efficiency, and also has a considerable impact on the control of reject rate. Therefore, the accuracy, effectiveness and stability of the cooking process are very important. [0003] A batch of glass delivered as a whole at a time is called a pot of glass. Because of the production process, the length and overall quantity of single glass contained in each pot of glass are determined according to the actual p...

AI Technical Summary

Problems solved by technology

[0004] The current split pot control is unstable. First, when entering the sputtering chamber, there is only one measuring point in the transition section of the inlet. Sometimes the calculated length data and the actual glass length have a large error.

Second, by sampling the motor transmission speed to track the transmission data, the transmission stability is relatively poor, especially when changing the motor speed

And there will be an error in the data tracking of one pot, and a corresponding transmission error in the next pot, forming a cumulative error

Third, when the system is switched to manual, data tracking is easy to lose

4. When an exception occurs, after the system is manually transferred, the data will be lost or messed up after the manual transmission. All the glass in the vacuum sputtering chamber needs to be transferred manually, which not only delays a lot of time for processing, but also increases the probability of the chamber glass colliding.
