Description

Technical Field

[0001] The utility model relates to the technical field of polaroid inspection, in particular to an automatic polaroid inspection and packaging device. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarizing films in front and back tightly attached to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. The basic structure of the polarizer includes polyvinyl alcohol in the middle, two layers of triacetate cellulose, pressure-sensitive adhesive, release film and protective film. Among them, the polyvinyl alcohol layer plays a polarizing role, but polyvinyl alcohol is easily hydrolyzed. In order to protect the physical properties of the polarizing film, a layer of film with high light transmittance, good water resistance and certain mechanical strength is compounded on both sides of the polyvinyl alcohol for protection.

[0003] With the continuous advancement of display technology, the application scope of polarizers has gradually expanded, and the demand has also gradually increased. At present, the post-processing stage of polarizers has basically achieved fully automated production, but large polarizers over 100 inches still rely on manual grading, testing and packaging. Compared with the TV and MNT models, which are fully automated from cutting and molding to shipment and packaging, there are certain risks in the manual handling of large polarizers: large polarizers are not easy to lift and move manually, which greatly increases the risk of manual damage during the handling process; the manual operation mode prolongs the operation time and reduces the output efficiency compared to the fully automatic mode. It is necessary to design an automatic inspection and packaging equipment for polarizers to solve the problem of handling the super-large 100-inch polarizers during the automatic inspection process.
