Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display processing, in particular to a polarizing film cutting edge cleaning device. Background Art

[0002] In electronic devices, polarizer is a very important part. It mainly helps the display to generate polarized light to realize the display function, removes unnecessary glare and reflection, and enhances the contrast and clarity of the image.

[0003] The polarizing function of the polarizer is realized by the polarizer (PVA layer). As a practical product, the polarizer must have high durability, ensure compatibility with the TAC layer, and have good heat resistance, moisture resistance, impact resistance, cold resistance and light resistance. Maintaining the shape of the polarizer and protecting PVA from moisture are achieved through the TAC layers on the upper and lower sides of the polarizer; photosensitive adhesive is the component that connects the polarizer and the glass substrate, and is required to have suitable adhesion. The original packaging sheets of the polarizer are separated by white paper. When cutting, the polarizer to be cut is placed on the table and covered with white paper for cutting. If glue overflows or foreign matter is attached to the cutting edge during the attachment process of the cut polarizer, it will not only cause product defects but also cause pollution to the production line. Therefore, the cleanliness of the polarizer is an important indicator of the patch process. Glue overflow or foreign matter on the cutting edge will cause some uneven display around the product after the polarizer is attached. In a high temperature and high humidity environment, the polarizer is prone to thermal shrinkage. In the existing technology, the cleaning of the cutting edge of the polarizer still relies on manual cleaning with a handheld tape, which is extremely inefficient.

[0034] In the embodiment, the support and steering member 3 is installed on the moving block of the transverse track conveying mechanism 2, and the support and steering member 3 is configured to carry the polarizer and realize the rotation of the polarizer; illustratively, as shown in the attached Figure 1 and 2 As shown, the supporting and steering member 3 includes a lower side plate 31 and an upper side plate 33 which are arranged in parallel and a plurality of support rods 34 connected therebetween.
