An automatic positioning, encapsulation and bonding equipment for polarizers and its production process

Abstract

The invention relates to the field of processing of polarizing films, in particular to automatic positioning packaging and attaching equipment of a polaroid and a production technology thereof. The equipment comprises a machine body, a cutting mechanism, a drawing mechanism, an up-rolling mechanism and a thin film removing mechanism which are arranged in the machine body. The machine body comprises two slide rails in approximate L shapes, the slide rails are horizontally arranged, a guide pulley is arranged in each slide rail respectively, the drawing mechanism can be movably arranged betweenthe two guide pulleys in the extending direction of the slide rails through the two guide pulleys, the up-rolling mechanism is arranged at the tail ends of the slide rails and can be vertically or horizontally and movably arranged through a linkage device, an attaching shaft capable of rotating around the axis is arranged between the tail ends of the two slide rails, an extending mechanism used for driving the attaching shaft to move vertically is arranged at the end of the attaching shaft, the thin film removing mechanism can be movably arranged to be directly close to or away from the attaching shaft through a hydraulic rod, and an anti-warping piece is arranged at the turning part of each slide rail. The automatic positioning packaging and attaching equipment of the polaroid can cut thepolaroid automatically and locate the end part of drawn and pre-attached polaroid.

Description

technical field [0001] The invention relates to the field of polarizing film processing, in particular to an automatic positioning, encapsulating and laminating equipment for a polarizing film and a production process thereof. Background technique [0002] The full name of polarizer is polarizer. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two front and rear polarizers attached to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1mm. If any one is missing Polarizers and LCDs cannot display images. [0003] There are many steps in the processing of polarizers, one of which is to attach the polarizing film to the main film material. The existing processing equipment is semi-automatic, that is, it can only automatically unwind and lay the polarizing film. However, the loading of polarizing film, unrolling and positioning of the end film are all done manually, so it is a waste of time, which...

[0003] There are many steps in the processing of polarizers, one of which is to attach the polarizing film to the main film material. The existing processing equipment is semi-automatic, that is, it can only automatically unwind and lay the polarizing film. However, the loading of the polarizing film, the unrolling of the end film and the positioning work are all done manually, so it is a waste of time, which in turn reduces the output in disguise.
