Device and method for supplementing and correcting cassette offset

Abstract

The invention provides a device for supplementing and correcting cassette offset. The device comprises a first axial ranging sensor, a first transverse ranging sensor, a second transverse ranging sensor, an offset calculator and a supplementing and correcting regulator, wherein the first axial ranging sensor is arranged at the tail end of a moving carrier and used for measuring a first axial distance value between the tail end of the moving carrier and a cassette; the first transverse ranging sensor and the second transverse ranging sensor are arranged at the same side of the moving carrier and used for respectively measuring a first transverse distance value between the side, on which the first transverse ranging sensor is arranged, of the moving carrier and the cassette and a second transverse distance value between one side, on which the second transverse ranging sensor is arranged, of the moving carrier and the cassette; the offset calculator is used for calculating an offset supplementing and correcting value of the cassette when the cassette is judged to undergo offset; and the supplementing and correcting regulator is used for regulating a motion trail of the moving carrier to complete the supplementing and correcting of the cassette so as to obtain the offset supplementing and correcting value. By adoption of the device and a method for supplementing and correcting the cassette offset, provided by the invention, the offset produced when the cassette is placed onto the moving carrier can be automatically supplemented and corrected, so that the moving efficiency of substrates is increased.

Description

technical field [0001] The present application relates to the field of plasma display screen manufacturing, in particular to a correction device and correction method for cassette offset. Background technique [0002] PDP (Plasma Display Panel) plasma screen has developed rapidly since its appearance, and has great market development potential, which has aroused the special attention of major manufacturers around the world. At this stage, it is mainly used for information display and automatic monitoring systems in public places such as airports, railway stations, exhibition venues, corporate seminars, academic conferences, and remote conferences. [0003] With the development of volumetric circuit components towards high-density design, the size of components defined on the glass substrate continues to decrease, making the related circuit design more complicated. It also leads to a considerable number of steps in the manufacture of related displays to produce the required ...

AI Technical Summary

Problems solved by technology

[0006] However, in actual operation, there will be some errors in the placement of the cassette on the carrier

Due to the small space reserved for the cassette in the process machine or warehouse, when the cassette is not placed in the standard position on the carrier, the cassette cannot be accurately placed in the reserved position of the process machine or warehouse. It is necessary to manually adjust the position of the cassette, resulting in low substrate handling efficiency and inconvenient operation
