Problems solved by technology
The adhesion of the frame glue after curing directly affects the sealing performance and reliability of the LCD unit. Therefore, it is necessary to test the adhesion of the frame glue in the LCD unit during quality inspection. In the current production and application process, there is no such frame The glue adhesion testing process mainly relies on visual inspection or manual force on the liquid crystal display unit and judgment based on experience, so there is an urgent need for a frame glue adhesion testing equipment that can be used in mass production

The invention discloses a frame glue adhesion detecting device for liquid crystal display. The frame glue adhesion detecting device comprises a clamping assembly, an auxiliary positioning assembly and a punching assembly, wherein the clamping assembly is used for clamping a glass panel in the thickness direction, the auxiliary positioning assembly is arranged beside the clamping assembly and comprises an auxiliary positioning face facing the clamping assembly and used for positioning the side face of the glass panel, the punching assembly comprises an ejector pin arranged between the clamping assembly and the auxiliary positioning face, the axis of the ejector pin is parallel to the auxiliary positioning face, and the ejector pin can reciprocate in the direction perpendicular to the clamping face of the clamping assembly. The glass panel is clamped by the clamping assembly in the thickness direction, the side face of the glass panel is positioned by the auxiliary positioning assembly, when frame glue adhesion of the glass panel punched by the punching assembly is detected, the edges of a glass panel sample can be reliably fixed, all test points of the boundary of the glass panel sample are uniform in stress, and the repeatability and accuracy of sample testing can be well ensured.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a frame glue adhesion force detection device for liquid crystal display. Background technique [0002] TFT-LCD (Thin film transistor-liquid crystal display, thin film transistor-liquid crystal display) is currently a display device that performs well in terms of brightness, contrast, power consumption, life, volume and weight. It has excellent performance and large-scale With good production characteristics, high degree of automation and broad development space, it has gradually occupied a dominant position in the display field. The liquid crystal panel is composed of TFT substrate (thin film transistor array substrate), CF substrate (color filter array substrate) and liquid crystal sandwiched between the two substrates. [0003] According to the current liquid crystal display unit manufacturing process, CF substrates or TFT substrates are coated with sealant afte...
