Description

a friction device

technical field

The invention relates to the technical field of liquid crystal display production, in particular to a rubbing device.

Background technique

In recent years, the TFT-LCD industry has developed vigorously, and product technology has become more and more advanced. We have put forward higher requirements for quality control in the production process of products. The rubbing process is to rub the glass substrate with a rubbing roller on the glass substrate before dropping the liquid crystal, so that the liquid crystal molecules can be arranged in an orderly manner. It is an important part of the box-making process, and the dust has a great impact on the rubbing process. Therefore, glass substrates must be cleaned by USC before entering the friction machine, and some advanced production lines are equipped with friction roller cleaning devices. However, since the current roll changing unit is designed in a closed space with the friction machine, it is inevitable that dust from the production line will enter the body of the friction machine when changing rolls, causing pollution to the friction environment; and the friction roll will also adhere to produce Line dust, and these dust will reduce the quality of the product. In addition, when using the current roll changing unit for roll changing, you must wait until the friction machine stops working and unlock the roll changing entrance door before pushing a new roll in for roll changing. This way of changing rolls caused the friction machine to be idle for at least 5 minutes, reducing the production efficiency of the entire production line. At the same time, after opening the roll change entrance door, the operator will directly face the inside of the friction machine, and there is a danger of being irradiated by the soft X-ray installed inside it, and there is a certain potential safety hazard.
