Problems solved by technology
[0004] 1. Different equipment uses the same process parameters in the production process, and the machine difference between the equipment cannot be adjusted in time during the production process, resulting in poor uniformity and stability of friction strength
[0005] 2. There are fluctuations in the friction cloth as a production raw material. These fluctuations need to be measured with professional equipment before reproduction, but the results of these measurements cannot be systematically and directly fed back to the friction equipment
[0006] 3. The property of the friction cloth itself is a changing process in the production process. There is no friction cloth monitoring device in the production process of the existing friction equipment. It can only be monitored theoretically through the accumulation of previous production data. It cannot be quantified for each time. Production is monitored
[0007] The above problems cannot be solved on the existing friction equipment, and these problems will cause fluctuations in product quality

Embodiment Construction
[0039] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0040] The elastic recovery force of the friction cloth is the elastic force in the opposite direction produced by the friction cloth when it is pressed down. Such as figure 1 As shown, the greater the pressing distance of the friction cloth, the greater the elastic recovery force of the friction cloth. figure 1 The middle abscissa is the pressing distance, and the ordinate is the elastic restoring force. With the use of friction cloth, the elastic recovery force of friction cloth will change to a certain extent (decreasing trend), the elastic recovery force of friction cloth will affect the friction effect, and the elastic recovery force measured by friction cloth with ...

Description
technical field [0001] The invention relates to a rubbing cloth monitoring device, a rubbing orientation device and a rubbing equipment adjustment method, belonging to the technical field of liquid crystal manufacturing. Background technique [0002] At present, in the TFT-LCD manufacturing industry, the method used in the manufacturing process of the alignment film is: first, the alignment film is coated on the inner side of the upper and lower electrode substrates of the liquid crystal display; the alignment film is rubbed with a rubbing cloth on the rubbing device. The alignment film after rubbing will produce grooves arranged in a certain direction, and the liquid crystal material can achieve the alignment effect due to the intermolecular force. [0003] Existing friction devices mainly have the following problems: [0004] 1. Different equipment uses the same process parameters in the production process, and the machine difference between the equipment cannot be adjust...
