AI Technical Summary
When laser cutting polarizers, the molten edge of the polarizer tends to stick to the leftover material, and the molten adhesive tends to adhere to the surface of the fixture plate, affecting the removal of the polarizer product and subsequent loading.
A POL cutting fixture was designed, including a substrate, a stage, a flange, a pressure ring, and a negative pressure chamber. By setting a discharge groove and a suction hole on the top of the stage, the molten raw material is adsorbed by negative pressure, which reduces the possibility of it adhering to the cut polarizer product and facilitates waste cleaning.
It effectively reduces the possibility of adhesion between molten raw materials and cut polarizer products, improves the efficiency of polarizer removal and the smoothness of subsequent feeding, and simplifies the waste cleaning process.
