Problems solved by technology

However, it is unavoidable that the general stirring rod will rub against the metal cup during the stirring process and produce metal powder
The metal powder mixed into the frame glue will often increase the defect rate of the product. In severe cases, the entire batch of display panels may have serious defects and have to be scrapped, causing great losses.

Embodiment Construction

[0018] Please refer to FIG. 1A , which shows a schematic diagram of a stirring rod in a preferred embodiment of the present invention. The colloid stirring rod 100 is used for stirring a colloid, and includes a main body 110 and a stirring part 120 . The colloid is, for example, a sealant used to form the injection region in the ODF manufacturing process of the liquid crystal display panel, and its main component is a high-viscosity polymer material. Please refer to FIG. 1B , which shows a schematic view of the main body of the stirring rod shown in FIG. 1A . The main body 110 is made of the first material, and the rigidity of the first material must be enough to stir the glue without breaking. The material of the first material may be an engineering plastic, such as polyetheretherketone (PEEK). Because this material has high mechanical strength, high rigidity, and high hardness, it can withstand high temperatures of 250°C-310°C without deformation. In addition, the materia...

Abstract

A colloid stirring rod is used to stir a colloid, including a main body and a stirring part. The main body is made of the first material, and the stirring part and the main body are detachable structures. The stirring part is made of the second material, and the second material has chemical resistance and wear resistance. The stirring part is set outside the main part and closely combined with the main part to stir the colloid.

Description

technical field [0001] The invention relates to a stirring rod, and in particular to a colloidal stirring rod with a detachable structure. Background technique [0002] At present, due to the increasing panel size in the panel industry, the traditional liquid crystal filling method is time-consuming and prone to defects. Therefore, most of them have introduced the one drop filling (ODF) liquid crystal filling process. First of all, this kind of manufacturing process preliminarily forms an implanted area on a glass substrate, such as a thin film transistor (thin film transistor, TFT) substrate or a color filter (color filter, CF) substrate, and then drips Drop the liquid crystal into the head; then, align another glass substrate with the substrate on which the liquid crystal has been dropped; then, bake the frame glue with ultraviolet light to harden the frame glue; then, cut the substrate into pieces to become A display panel completed by pouring liquid crystals into multip...
