Rotary press table for machining laminated polarizers in middle and small size

Abstract

The invention discloses a rotary press table for machining laminated polarizers in middle and small size. The rotary press stable solves the problems of complicated structure, low positioning precision and inconvenience in operation of the existing equipment and comprises a framework, an upper rotary table and a lower rotary table. The upper rotary table is fixedly arranged on a horizontal cross beam on the upper portion of the framework. A direct-drive motor rotary table which is hollow is arranged on the upper portion of an upper rotary table fixed plate, a spline shaft of a ball spline pair penetrates through a center hole of the direct-drive motor rotary table and the center of a spacer sleeve, the upper end of the spline shaft is connected with a push rod of an air cylinder through a spline connecting flange, two thrust bearings, a transfer shaft and a floating joint, and the lower end of the spline shaft is connected with an upper press head through an upper press head connecting flange. The lower rotary table is fixedly arranged on a bottom frame of the framework through a lower rotary table fixed plate, and the other direct-drive motor rotary table is fixedly arranged on the lower rotary table fixed plate. By the rotary press table, a stack of laminated polarizers can be pressed, positioned accurately and rotate synchronously.

Description

technical field [0001] The invention relates to a side edge processing device of a liquid crystal polarizer, in particular to a pressing and rotating mechanism for cutting and processing the edge of a polarizer of a liquid crystal display with a small or medium size. Background technique [0002] Liquid crystal polarizers are part of the display screens of computers and mobile phones. At present, the shearing process is mainly used for small and medium-sized polarizers, and its side dimension accuracy and surface quality cannot meet the requirements of high-end products. Polarizer side processing equipment is to stack the cut polarizers into a stack and then perform precision cutting on the side. Since the polarizer has a layered structure, the layers are coated with viscous materials, each polarizer has a small thickness and a smooth surface. When a stack of polarizers are stacked and pressed together for processing, when the pressing pressure is small, it cannot be corre...
