Background

At present, in the existing traditional polaroid cutting production process, the molds are required to be opened according to different sizes in the cutting process, each set of molds can only cut one single size correspondingly, and finished products after cutting are required to be subjected to edging treatment. The consumption of auxiliary materials such as a cutting die, an edging cutter and the like in the cutting and grinding process is too high. And the flow is complicated.

In the existing polaroid laser cutting production process, the maximum linear speed of the laser cutting polaroid is about 200mm/s due to technical reasons, and when the cutting size is large, the time consumed by cutting is correspondingly long. Therefore, when the current laser cutting is applied to large-size cutting, the efficiency is very low.

In view of the above, for cutting large-size polarizer products, it is necessary to provide a cutting device with low cost, simple processing flow and high efficiency.

Chinese patent CN216758617U discloses a method for laser cutting processing of polarizer, which mainly comprises cutting raw materials into master, positioning, splitting, conveying to a cutting platform to cut small pieces, conveying to a distributing table via a blanking mechanism, and butt-jointing the rear ends for a series of processing. The processing mode is only suitable for cutting products smaller than or equal to 15 inches, when cutting large-size products, the cutting stroke is limited by the speed of a laser cutting line, and the method disclosed by the patent requires a mechanical arm to transfer the products, and the waiting time is long, so that the processing efficiency is too low, and the aim of the utility model cannot be realized.

Chinese patent CN213794862U discloses a method for laser cutting processing of a polarizer, in which a polarizer master is placed on a flow belt of a cutting table mainly through a suction device, left and right cutting of the polarizer is completed through left and right movement of the flow belt, and then front and rear cutting of the polarizer is completed through front and rear movement of a laser device on a cross bar, so as to obtain a final product. The processing mode needs to divide the cutting work into two parts of left and right cutting and front and back cutting, and the aim of the utility model can not be realized. The process is relatively complex and the limit of the laser cutting line speed cannot be solved.
