Polaroid bubble-free laminating device

Abstract

The invention discloses a polaroid bubble-free laminating device. The device comprises a support. One side of the upper end of the support is fixed with two first installation plates. The two first installation plates are rotatably connected to an adhesive cloth recovery shaft. One end side wall of the one first installation plate is provided with a third torque motor. The tail end of the output shaft of the third torque motor is fixed to one end of the adhesive cloth recovery shaft. The two first installation plates are provided with first openings. A first support block is fixed to one end side wall in each first opening. Through improving the laminating device, a problem that bubbles are easy to generate during an attaching process is solved. Attaching quality is improved, cost is reduced, shutdown time is shortened, production power is increased and the replacing frequency of viscose cloth is reduced; attaching efficiency is increased, and a service life is prolonged; and through the accurate adjusting of an adjusting valve and a tensioning cylinder, the tensile force of the viscose cloth is always maintained and usage is convenient.

Description

technical field [0001] The invention relates to the technical field of laminating polarizers, in particular to a device for laminating polarizers without air bubbles. 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. [0003] At present, metal vacuum suction cups are often used to attach polarizers on the market. A short section of the polarizer is exposed from the suction cup. The sticking rubber roller (46) is pressed down to make the polarizer stick to one end of the glass, and the glass is moved to make the polarizer stick. on the glass. This method of application is prone to air bubbles at the initial position of application; and during the application process, the polarizer is prone to drop on the glass due to poor vacuum s...

AI Technical Summary

Problems solved by technology

Although the problem of vacuum adsorption is solved, due to the limited application times of the adhesive cloth at the same position, it is often necessary to stop the machine to replace the adhesive cloth, resulting in a loss of production capacity; each piece of the annular adhesive cloth needs to be rotated, which is prone to dust falling. There is a liquid crystal glass without a polarizer on the bottom. The liquid crystal glass is very strict against dust falling, which has a great impact on the quality of the paste. Therefore, we propose a polarizer without bubble bonding device to solve the above problems
