Description

Technical Field

[0001] This patent application relates to the field of automatic tape application and transportation of large-generation glass substrates, and in particular to an efficient tape application device for glass substrates of 0.5 mm and below. Background Art

[0002] With the rapid development of the LCD industry, people's demand for displays is increasing, and the production capacity of LCD panels has also greatly increased to keep up with the increasing demand; therefore, the production speed and efficiency of LCD panels are particularly important. The production process of LCD panels involves some tape sticking processes; for example, the process of evaporating AR coating layer on the surface of LCD panels requires sticking many pieces of tape on a large substrate.

[0003] In the prior art, there are two working principles of automatic tape machines. The first one: for a carrier board that is relatively thick and high in strength, the tape machine can work directly on its surface to apply tape. This method is not suitable for liquid crystal panels, because the panel is made of thin glass, and the tape applying mechanism will cause the panel to break. The second one: the substrate is taken out from the roller conveyor device by a transfer mechanism and transported to the tape applying platform for tape application. After the tape application is completed, the transfer mechanism returns the substrate to the roller conveyor device. This method is the current method for applying tape to glass substrates in the panel manufacturing industry; this method involves three workstations to achieve the tape application of the substrate; this method has the problems of large equipment space occupation, slow glass conveying speed, low efficiency and high production cost.

Nine rollers 2.1 are equidistantly mounted on the shaft 2.2 on the glass conveying mechanism 2 to form a roller group. Twenty-one rows of roller groups are equidistantly mounted on the frame 2.3; a motor 2.4 is mounted on the frame 2.3 and connected to the shaft 2.2 through a bevel gear; when the motor 2.4 rotates, it can drive the rollers 2.1 and the shaft 2.2 to rotate. There are four sensors 2.5, which are arranged in sequence in the middle of the roller group; the four sensors 2.5 are used to detect the position of the glass substrate 3; the signals of the four sensors 2.5 are respectively defined as: entry, deceleration, stop, and outflow signals. There are eight correction mechanisms 2.6, which are distributed in the middle of the roller group and are used to correct and position the glass substrate position 3.
