Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a fully automatic special-shaped polarizer bonding machine and a bonding process thereof. Background technique [0002] Glass substrates and polarizers are the most basic assembly materials in the production and assembly process of mobile phone screens and TV screens. Glass substrates are used as carriers. Various optical requirements can be achieved by attaching polarizers to the surface of glass substrates. According to the characteristics of the glass substrate, it is divided into flexible screen or rigid screen. In the actual manufacturing process of the display, a polarizer needs to be attached to the surface of the glass substrate. With the continuous improvement of display manufacturing technology, foreign display manufacturers have gradually introduced automated production lines into screen manufacturing. Domestic screen manufacturers have also increased investment in ...

AI Technical Summary

Problems solved by technology

[0003] The following technical problems need to be solved in the process of upgrading the automatic production line of polarizer lamination: 1. Since the polarizer lamination process involves the process requirements of attaching polarizers to both sides of the glass substrate, the traditional attachment equipment Generally, the glass substrate is placed flat on the stacking platform and then the polarizer is attached to the surface of the glass substrate. The requirements for the reverse attachment process of the glass substrate cannot be met, so it is necessary to solve the problem of the reverse attachment. In the actual processing process , the front and back sides of the glass substrate often need to attach polarizers. At this time, after a piece of glass substrate is pasted, the glass substrate needs to be rotated 180° to attach a polarizer on the other side. Based on the above process requirements, it is necessary Solve the problem of automatic connection of glass substrates between different stations and the exchange of glass substrate attachment surfaces; 2. Before attachment, it also involves automatic loading and transfer of glass substrates and polarizers; 3. Traditional The attachment process is generally a single patch, that is, the material is attached after one application. This process has a standby time, that is, it cannot be attached when the polarizer is loaded, and it cannot be loaded when it is attached;4 . Since the surface quality needs to be guaranteed before placement to improve the yield rate of subsequent placement, it is necessary to solve the surface cleaning and detection problems of glass and polarizers before placement; 5. During the placement process, polarizers made of flexible materials When attaching to the glass substrate, it is necessary to solve the problem of bonding air bubbles; 6. In addition, the surface of the polarizer is covered with a protective film when it is supplied, so it is necessary to solve the problem of automatic tearing of the film before the patch; 7. On the glass After the polarizer is attached to the base material, the positional error of the polarizer will be caused by the possible positional deviation during the attachment process. Therefore, it is necessary to solve the problem of the position accuracy detection of the polarizer; especially for special-shaped polarizers, due to Its size or position to be inspected is irregular, which is more difficult than traditional inspection
