[0002] Polarizer, also known as polarizing film, is one of the imaging components of liquid crystal display. Polarizer is punched out from polarizer master (polarizing tape). The master usually comes in the form of roll material. The roll material is unwound into a strip shape and passed through the die-cutting machine on the conveyor line, and then punched out to form polarizer.

[0003] Chinese patent announcement number CN213766121U discloses an automatic polarizer film collection device, including a polarizer belt conveyor line arranged below a die-cutting machine, a stripping roller is arranged at the end of the polarizer belt conveyor line, a transfer roller is arranged at the lower left of the stripping roller, a waste winding roller is arranged at the lower right of the transfer roller, an inclined film collection slot is arranged below the stripping roller, and the film collection slot is provided with a rectangular through hole through which the polarizer belt passes. The film collection device can automatically collect the film, and the polarizer belt is suddenly bent by the stripping roller, and the polarizer on the polarizer belt is tilted and automatically detached from the polarizer belt, falls into the film collection slot and falls into the next conveyor line for sorting, and the film collection is completed. The whole process does not require manual film collection, thereby improving the production efficiency of the polarizer.

[0004] However, the above technical solution has the following shortcomings: when the polarizer is detached by the stripping roller, the polarizer is detached directly from the side close to the stripping roller to the other side, which not only has large friction, but also easily causes the edge of the polarizer to be easily worn. In addition, when the material of the polarizer is relatively soft, it sometimes follows the bending of the mother tape through the rectangular through hole and cannot be collected.

DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figure 1-Figure 4 As shown, a polarizer punching and collecting device proposed in this embodiment includes a workbench 1 and a collecting device; a collecting trough and two symmetrically distributed supports 2 are provided on the workbench 1; the collecting device is arranged on the workbench 1, and includes a pressing mechanism arranged on the support 2, two vertical plates 13 arranged in the collecting trough and vertically distributed, a collecting box 25 arranged in the collecting trough, and a collecting mechanism arranged on the vertical plate 13, the pressing mechanism includes a pressing plate 7 with a groove arranged at the bottom and three rollers 8 horizontally distributed in the groove in sequence, a driving component for driving the pressing plate 7 to move vertically, and a connecting component for connecting the driving component and the pressing plate 7, and the collecting box 25 is located at the lower side of the collecting mechanism.

[0022] The pressing mechanism includes a support frame 3 arranged on a support 2, a first cylinder 4 vertically arranged on the support frame 3, and a piston rod 5 drivingly connected to the first cylinder 4. The connecting assembly includes a fixed block 6 arranged at the bottom end of the piston rod 5 and a connecting block 9 arranged on a pressing plate 7. A rectangular groove for inserting the connecting block 9 is arranged inside the fixed block 6. The connecting assembly also includes a bolt 10 threadedly connected to the connecting block 9 and a nut 11 threadedly connected to the bolt 10. The bolt 10 passes through the fixed block 6 and the connecting block 9, and the nut 11 abuts against the fixed block 6. The pressing plate 7 can be replaced according to the size of the punched polaroid to ensure that the force area of ​​the pressing plate 7 on the polaroid is appropriate, so as to facilitate the detachment of the polaroid.

[0023] The material receiving mechanism includes a roller 12 located below the pressing mechanism, a slideway arranged on the vertical plate 13 and distributed vertically, a slider 16 slidably arranged in the slideway, a motor 14 arranged on one side of the slider 16, a rotating shaft 15 arranged at both ends of the roller 12 and a recovery component for supporting the slider 16, the motor 14 is drivingly connected to the rotating shaft 15, the rotating shaft 15 is rotatably connected to the slider 16, the supporting component includes a support rod 17 arranged at the bottom of the slider 16, a fixed cylinder 18 vertically arranged on the vertical plate 13, and a spring 19 connected to the support rod 17 and the fixed cylinder 18 at both ends respectively, the spring 19 is arranged inside the fixed cylinder 18, when the slider 16 is located at the top of the slideway, the spring 19 is still in a compressed state, and the spring 19 has a high stiffness coefficient to avoid long-term oscillation of the spring 19 when it returns to its initial height.

[0024] In this embodiment, when the cut polaroid and the mother tape are transported to the bottom of the pressing mechanism, the first cylinder 4 is started to drive the piston rod 5 to extend, and the piston rod 5 pushes the pressing plate 7 to descend until the roller 8 squeezes the punched polaroid. Since the roller 12 is in contact with the bottom of the polaroid, the roller 12 is also pushed downward, so that it supports the polaroid, avoiding the middle part of the polaroid being much larger than the edge, resulting in an irreversible deformation of the middle part, thereby reducing the quality of the workpiece. At the same time, the spring 19 will be compressed so that the side of the polaroid can be separated from the edge of the mother tape punching. When the polaroid is separated from the mother tape downward, the motor 14 is started to drive the rotating shaft 15 to rotate, and the rotating shaft 15 drives the roller 12 to rotate. In cooperation with the rolling effect of the roller 8, the polaroid between the roller 12 and the roller 8 is transported outward until the polaroid is transported into the receiving box 25, and then the motor 14 is turned off, and the first cylinder 4 drives the piston rod 5 to rise and restore the initial height. The roller 12 also restores the initial height under the action of the spring 19, so as to facilitate the next collection of the polaroid.

[0025] Embodiment 2

[0029] In this embodiment, the mother tape is conveyed by a conveying device (not shown). When the mother tape is located at the processing position of the cutting mechanism, the second cylinder 22 is started to drive the connecting seat 23 to descend, and the connecting seat 23 drives the cutting die 24 to descend, so as to punch out the polarizer from the mother tape, and the polarizer continues to be conveyed with the mother tape until the polarizer is detached from the mother tape and collected.
