Transmission system capable of adjusting tension of base materials and control method thereof

Abstract

The invention discloses a transmission system capable of adjusting tension of base materials and a control method thereof. The transmission system comprises a transmission mechanism and a roller assembly. The transmission mechanism drives the base materials to move along a transmission method. The roller assembly comprises an adjusting roller provided with a first end and a second end. The second end moves relative to a first end selectively. The adjusting roller is used for abutting against with the base materials and allowing the base materials to be arranged between the second end and the first end in a crossed manner. When the second end moves relative to the first end, the axis of the adjusting roller deviates so as to provide component force on the surfaces of the base materials and adjust the tension of the base materials, wherein an included angle is formed between the component force and the transmission direction. Thus, the tension borne by the base materials is evened and the base materials are effectively led to move along the transmission direction, so yield rate of the finished products of follow-up manufacture procedures or processing of the base materials is increased.

Description

technical field [0001] The invention relates to a transmission system for conveying substrates, in particular to a transmission system capable of adjusting the tension of substrates and a control method thereof. Background technique [0002] Washing machine, developing machine, etching machine, stripping machine, coating machine, exposure machine, slitting machine, cutting machine, printing machine, laminating machine, chemical liquid deposition equipment (CBD) and other machines have a transmission mechanism. The transmission mechanism is used to drive the film-shaped substrate to move along a conveying direction, so as to facilitate the process or processing on the film-shaped substrate. [0003] When the traditional transmission mechanism transports the film-shaped substrate, it is easy to have problems such as uneven tension of the film-shaped substrate and the deviation of the film-shaped substrate from the centerline of the transmission direction, which will cause the...

AI Technical Summary

Problems solved by technology

[0003] When the traditional transmission mechanism transports the film-shaped substrate, it is easy to have problems such as uneven tension of the film-shaped substrate and the deviation of the film-shaped substrate from the centerline of the transmission direction, which will cause the film-shaped substrate to accumulate tension and be deformed or damaged, or the film-shaped substrate Deviating from the center line of the transmission direction causes manufacturing process or processing errors, which in turn greatly reduces the process yield and affects the profit of the industry

[0004] However, taking the film-shaped substrate rolled by at least two rollers in the transmission mechanism as an example, in order to solve the problem of uneven tension of the film-shaped substrate, the practice is to adjust the tension control of the film-shaped substrate through the speed difference between the rollers , but for the problem that the film-shaped substrate deviates from the centerline of the roller transmission direction, an additional electronic device is used for forced correction. This electronic device is expensive and difficult to install, so the above-mentioned problems still cannot be properly improved
