Three-axis adjusting device for spacing paper taking machine and adjusting method thereof

Abstract

The invention discloses a three-axis adjusting device for a spacing paper taking machine and an adjusting method thereof. The structure of the three-axis adjusting device comprises a support frame, an X-axis walking unit and a second sliding pair, wherein the X-axis walking unit is assembled on the support frame by means of a first sliding pair; the second sliding pair is arranged on the bottom surface of the X-axis walking unit; a Z-axis rotating mechanism is fixedly connected to a sliding component of the second sliding pair; the rotating end of the Z-axis rotating mechanism is fixedly connected with the spacing paper taking mechanism; and the spacing paper taking mechanism has an adjusting degree of freedom along an X axis, the second sliding pair and a Z axis by means of the X-axis walking unit, the second sliding pair and the Z-axis rotating mechanism. Moreover, the adjusting amount and adjusting direction of the Z-axis rotating mechanism are calculated and adjusted by adopting a PLC (Programmable Logic Controller), so that the parallelism of a paper taking unit and a glass substrate can be controlled accurately, and the paper taking success rate is increased; and moreover, the three-axis adjusting device is simple in structure, and is low in cost.

Description

technical field [0001] The invention relates to the field of plasma (PDP) glass substrate processing, in particular to the field of spacer paper handling at the input end of the glass substrate, in particular to a three-axis adjustment device and an adjustment method for a spacer machine. Background technique [0002] Plasma display is a new generation of display following CRT and LCD. It came out in the 1960s and began mass production in the mid-1990s. It is currently recognized as the most promising device for realizing high-definition digital TV and large-screen wall-mounted TV. With the continuous expansion of the size of the plasma TV screen, the size of the glass substrate is also expanding, which has been expanded to 2470mm×2310mm, and the requirements for the processing, storage and packaging of the glass substrate are getting higher and higher. [0003] In the prior art, it is often necessary to place the processed glass substrate on the A-frame and transport i...

AI Technical Summary

Problems solved by technology

Insufficient A-frame accuracy, inaccurate positioning of the turntable, or inconsistencies in the placement of glass substrates will cause the two-axis controlled paper picker to be out of parallel with the position of the glass substrate on the A-frame, resulting in failure to pick up paper

As the size of the glass substrate increases, improving the positioning accuracy of the A-frame and the turntable becomes a difficult point, and the processing and debugging costs cannot be ignored; if a high-precision robot is used to pick up paper, there are also design difficulties and increased costs.
