Problems solved by technology

[0005] Through the analysis and research of the existing technology, it is found that the following problems still exist in the current structure design of the blister tray for liquid crystal display and the production and processing technology of the blister tray: 1. The structure of the blister tray has high requirements for flatness and precision. There are also certain requirements for stability and safety during stacking and transportation, and there are many supporting components for LCD screens, so it is necessary to design a variety of accommodating cavities and buckle structures to meet the needs of use; 2. Blister molding during production and processing The cutting and forming process needs to be carried out immediately, but there is a lack of effective cutting distance adjustment control, and the separation of formed and unformed products cannot be carried out in time, which makes the production efficiency of the production line low and the scope of application is small; 3. Raw materials for blister trays The sheet material is generally made of PET or PVC, which has good processability and mechanical properties, but the antistatic property needs to be further improved, and a standardized and clean production process is required

Abstract

The invention discloses a blister tray for a liquid crystal display and its processing technology. The blister tray is improved in structure on the basis of a frame body composed of a protruding outer frame and a concave inner frame. Setting multiple depressions, reinforcing ribs, weight-reducing grooves, and sinking grooves not only facilitates the compact stacking of blister trays up and down, facilitates transportation, and improves safety, but also supports the various components of the LCD screen to achieve liquid crystal display. Stable placement and transportation of screen pairs; the processing technology of the blister tray of the present invention includes raw material preparation, feeding heating, blister molding, cutting, stacking points, transmission inspection, and the process design is scientific and reasonable. Combined with the supporting production line, the production efficiency is high ,Wide range of applications.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a blister tray for a liquid crystal display and its processing technology. Background technique [0002] Blister trays, also known as trays, are mainly used to package products to prevent them from being affected by external forces or external environments during production or transportation, and can also be used to temporarily place raw materials, semi-finished products or finished products. General electronic products, such as mobile phones, MP3, MP4, GPS, semi-finished products or finished products of LCD screens, need to be packed in blister trays and cartons. [0003] At present, for liquid crystal display products, the commonly used materials for its blister trays need to meet strict anti-static requirements, and the anti-static index is 10 5 Ω≤R≤10 11 Ω, commonly used materials are PVC, PS, PP, ABS, PET. At present, the common processing technology of bliste...
