Description

Technical Field

[0001] The utility model relates to the technical field of polarizer processing, and specifically relates to a polarizer edge cutting device. Background Technique

[0002] During the use of the existing polarizer edge cutting device, due to its suspended positioning mechanism, the polarizer is in a suspended state after being clamped and fixed. At present, most polarizer materials are soft and will bend after being suspended, making it impossible to use a rotary blade for edge cutting. At the same time, the debris generated by rotary edge cutting needs to be collected using a supporting collection device, greatly increasing the cost.

[0003] In the authorized Chinese utility model patent with the publication number CN219153105U and the name of a polarizer edge cutting device, it includes a device main body. The device main body includes a machine table, a motor, a transmission block, a lead screw, and an electric push rod. The telescopic part of the electric push rod is fixedly connected with a fixing part. The fixing part includes a pressing plate, a spring, and a pull rod. The output end of the motor is fixedly connected with a blade. One side of the machine table is fixedly connected with a support plate. The top of the support plate is fixedly connected with an L-shaped plate and a dust suction mechanism. The dust suction mechanism is arranged on the L-shaped plate and is used to suck the waste chips and dust generated after cutting. The dust suction mechanism includes a dust removal fan, a filter frame, a mounting plate, a support plate, three connecting pipes, and a dust suction hood. After the fixing part in this patent solution presses and fixes the polarizer, the whole polarizer is higher than the surface of the machine table, and the polarizer will bend under the action of gravity, making it impossible to perform edge cutting operations. Moreover, a large amount of debris generated by the rotary edge cutting method of the blade needs to be removed using a complex dust suction mechanism composed of multiple parts, not only greatly increasing the cost, but also requiring frequent cleaning and having a high failure rate.

[0004] In view of the problems existing in the existing polarizer edge cutting device, it is necessary to provide a new technical solution. Content of the Utility Model

[0031] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0032] A polarizer edge-cutting device, which includes:

[0033] Equipment rack 1, a first servo motor 2 is fixedly installed inside the bottom of the equipment rack 1. At the end of the output shaft at the top of the first servo motor 2, a storage tray 3 is fixedly installed. At the bottom surface of the horizontal part at the top of the equipment rack 1, a top shaft 4 is installed. At the bottom end of the top shaft 4, a base plate 5 is fixed.

The centers of the storage tray 3, the top shaft 4, the base plate 5, and the positioning plate 7 are on the same vertical line. The diameter of the positioning plate 7 is less than 1 / 3 of the diameter of the storage tray 3. The above structural design enables the positioning plate 7 to be stably aligned with the storage tray 3, stably extrude the polarizer on the storage tray 3, and the positioning plate 7 does not block the blade 15. The first electric telescopic rods 6 are symmetrically distributed about the center of the positioning plate 7. The center of the positioning plate 7 and the center of the blade 15 are on the same vertical plane. The above structural design enables the first electric telescopic rods 6 to stably drive the positioning plate 7 to move vertically, facilitating the blade 15 to stably trim the polarizer fixed by the positioning plate 7;

The top surface of the movable plate 10 is in contact with the bottom surface of the horizontal part at the top of the equipment rack 1. The above structural design enables the horizontal threaded rod 9 to stably drive the movable plate 10 to move along the bottom surface of the horizontal part at the top of the equipment rack 1 when rotating;

[0035] Movable plate 10, a stabilizing plate 11 is fixedly installed on the top surface of the movable plate 10.

The movable plate 10 drives the second electric telescopic rod 13, the mounting clamp 14 and the blade 15 to move synchronously until the bottom end of the blade 15 is vertically aligned with the position where the polarizer needs to be trimmed. Control the second servo motor 8 to stop working and lock the horizontal threaded rod 9. The horizontal threaded rod 9 fixes the horizontal positions of the movable plate 10, the second electric telescopic rod 13, the mounting clamp 14 and the blade 15 through thread self-locking. Control the second electric telescopic rod 13 to extend, push the mounting clamp 14 and the blade 15 to move vertically downward, and vertically cut the edge of the polarizer on the positioning disc 7 below the blade 15. Subsequently, control the second electric telescopic rod 13 to shorten, drive the mounting clamp 14 and the blade 15 to move upward. Again, control the first servo motor 2 to drive the placing disc 3 to rotate through the output shaft, so that the placing disc 3 drives the polarizer, the positioning disc 7, the first electric telescopic rod 6 and the substrate 5 to rotate synchronously around the top shaft 4, align the untrimmed side of the polarizer parallel to the blade 15. Control the first servo motor 2 to stop working and lock the placing disc 3. Subsequently, control the second electric telescopic rod 13 to extend again, drive the blade 15 to move vertically downward for re-cutting. Repeat the above steps to complete the trimming of all edges of the polarizer. Control the first electric telescopic rod 6 to shorten, drive the positioning disc 7 to move upward, no longer squeeze and fix the polarizer, and remove the polarizer.
