Description

Technical Field

[0001] The present invention relates to the technical field of polarizers, and in particular to a polarizer cutting device. Background Art

[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarizers in front and back that are tightly attached to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. Due to the different sizes of liquid crystal glass, the required size of polarizers is also different, so the polarizers must be cut. However, when cutting the polarizer, the polarizer is prone to offset or fluctuation, resulting in inaccurate cutting position and affecting the cutting quality. In addition, when cutting the polarizer, the existing cutter has a fixed size of cut polarizer due to the fixed size of the cutter, and it is impossible to cut polarizers of different sizes, which is inconvenient for people to use.

[0042] Working principle:

[0043] When the polarizer needs to be cut and fixed, the first cylinder 1101 moves to drive the first slider 1113 to slide in the second groove 1112, and the movement of the first slider 1113 drives the first connecting rod 117 rotatably connected thereto to move. The first connecting rod 117 is rotatably connected to the first telescopic rod 5, so the first connecting rod 117 pushes the first telescopic rod 5 to move. Since the structures of the first driving member and the second driving member are exactly the same, the first telescopic rod 5 and the second telescopic rod 6 rotate in the first rotating groove 11 respectively. When the first cylinder 1101 stops moving, the first telescopic rod 5, the second telescopic rod 6 and the first fixed block 116 are at a vertical angle, and the movement of the first telescopic rod 5 and the second telescopic rod 6 drives the first roller 16 rotatably connected thereto to move. At this time, the polarizer wrapped around the first roller 16 is pulled, and the polarizer is passed through the top and bottom of several second rollers 110 in the fifth rotating groove 19, so that the polarizer can be supported and polarization can be facilitated. The transmission of the film, and then the polarizer is inserted into the second through hole 231 on the first support block 237, so that the polarizer passes between the third roller 2313 in the third rotating groove 2311 and the fourth roller 232 in the fourth rotating groove 2312. Since the two ends of the fourth roller 232 are respectively rotatably connected to the first pushing frame 233 and the second pushing frame 234, the first pushing frame 233 and the second pushing frame 234 are respectively slidably connected to the two sides of the first support block 237, and the fourth roller 232 is driven away from and close to the third roller 2313 by driving the movement of the first pushing frame 233 and the second pushing frame 234, so that the polarizer can be fixed and clamped, and at the same time, the polarizer can be protected to prevent the polarizer from being scratched on uneven places and causing damage. At this time, the polarizer is continued to be pulled to be flattened on the cutting plate 212. Since the structures of the first support member 23 and the second support member 24 are exactly the same, the polarizer is passed through the second support member 24.

[0044] At this time, the second cylinder 25 and the third cylinder 26 fixedly connected to the support frame 22 move, driving the sliding block 27 to slide downward in the support frame 22. At the same time, the sliding block 27 slides on a plurality of sliding posts 29 in the support frame 22. The movement of the sliding block 27 drives the movement of the rotating shaft 281 fixedly connected thereto. The movement of the rotating shaft 281 drives the movement of a plurality of rotating disks 282 fixedly connected thereto. The rotating disk 282 drives the movement of a plurality of cutters 283 threadedly connected thereto. When the sliding block 27 moves, The first sliding rod 210 fixedly connected thereto moves, and the first sliding rod 210 drives the second sliding rod 211 slidably connected thereto to move. When the sliding block 27 slides downward, the second sliding rod 211 first touches the polarizer on the cutting plate 212 to fix the polarizer, and then the cutter 283 on the rotating disk 282 cuts the polarizer, and the cut polarizer slides through the second sliding groove 289 into the storage box 291 in the first sliding groove 290, thereby realizing the cutting, fixing and storage of the polarizer. The rotating shaft 281 is driven by rotating the driving disk 287 to rotate, and the rotating shaft 281 drives the plurality of rotating disks 282 fixedly connected thereto and the plurality of cutters 283 on the rotating disks 282 to rotate, thereby adjusting the cutters 283 of different sizes to realize cutting of polarizers of different sizes.

[0045] After the polarizer is cut, the second cylinder 25 and the third cylinder drive the sliding block 27 to move upward, and at this time, the polarizer is pulled to pass between the fifth roller 34 and the sixth roller 35 on the first connecting plate 32 and the second connecting plate 33, and then the polarizer is wound onto the seventh roller 38 on the third connecting plate 36 and the fourth connecting plate 37, so as to collect the residual polarizer.

[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form.
