[0002] The borderless TV structure is becoming more and more popular among consumers, and it has also been tested and recognized by the market. Correspondingly, the manufacturing process used for TVs with borderless structure design has also changed. The excellent appearance experience is the market demand, but reliable quality assurance is the soul of the product. The traditional structure of LCD TVs is mainly wrapped and fixed by plastic or metal parts on all sides, while the borderless structure of TVs cancels the wrapping of the three sides of the sky, left and right. During the screen assembly process, the screen edge and other parts of the product, such as the main body, middle frame, frame, etc., need to be connected, fixed and sealed. Generally speaking, this process requires the use of adhesive layers such as 3M glue and double-sided tape to paste, and then achieve connection and fixation. After pasting, it is generally necessary to maintain pressure for a certain period of time and apply pressure to the assembly so that the screen and the adhesive layer can be completely bonded and firmly, ensuring the tightness of the overall assembly of the product.
