Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of liquid crystal dimming film processing, and in particular to a device for removing residual solidified particles after cutting liquid crystal dimming film. Background Technology
[0002] In the processing of digital liquid crystal display (PDLC) films, laser cutting is becoming increasingly common. However, after laser cutting, black solidified particles from the ablation of the PET substrate are left at the cut edges. These solidified particles not only affect the aesthetics but can also cause localized edge arcing or short circuits in the PDLC film, making subsequent processing difficult. Currently, the most common method to remove these solidified particles is to wipe them back and forth with a hand-held lint-free cloth and alcohol. However, due to the strong adhesion of the ablated solidified particles, wiping is laborious and inefficient, affecting the production efficiency of PDLC films. Utility Model Content
[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a device for removing residual solidified particles after cutting liquid crystal dimming film to solve the above-mentioned technical problems.
[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:
[0005] According to one aspect of this utility model, a device for removing residual solidified particles after cutting a liquid crystal dimming film is designed, comprising:
[0006] A longitudinal drive unit is used to drive the first platform to move longitudinally.
[0007] A lateral drive unit is mounted on the first platform, and the lateral drive unit is used to drive the second platform to move laterally.
[0008] A fine-tuning drive unit, mounted on the second platform, is used to fine-tune the lateral movement of the mounting base;
[0009] A polishing drive unit, mounted on the mounting base, is used to drive the polishing wheel to rotate;
[0010] The detection unit is installed at the left end of the mounting base with its detection end facing downwards, and is used to detect the edge of the liquid crystal dimming film;
[0011] The control device is electrically connected to the longitudinal drive unit, the transverse drive unit, the fine-tuning drive unit, the polishing drive unit, and the detection unit.
[0012] Using the above technical solution, when using this device, it is placed on one side of the worktable, the liquid crystal dimming film is placed on the worktable, and the side where the solidified particles need to be removed is suspended outside the worktable, corresponding to the polishing wheel. Then, the liquid crystal dimming film is pressed down by the pressure block. The starting of each driving component of this device is controlled by the control device. After the device is started, the horizontal driving unit starts to drive the second platform to move to the left, which in turn drives the fine-tuning driving unit, the mounting base, the polishing driving unit, and the polishing wheel to move to the left. After the polishing wheel is close to the liquid crystal dimming film, the control device controls the horizontal driving unit to stop. Then, the polishing driving unit starts to drive the polishing wheel to rotate, and the fine-tuning drive... The drive unit starts and drives the mounting base to move to the left, which in turn moves the mounting base, polishing drive unit, and polishing wheel to the left, bringing the polishing wheel close to the liquid crystal dimming film. When the detection unit detects the edge of the liquid crystal dimming film, it feeds back information to the control device. The control device then controls the fine-tuning drive unit to stop. At this point, the polishing wheel contacts the liquid crystal dimming film. Then, the longitudinal drive unit starts and drives the first platform to move longitudinally, which in turn moves the polishing wheel longitudinally. The polishing wheel removes the solidified particles on the edge of the liquid crystal dimming film. Thus, this device can automatically remove solidified particles from the edge of the liquid crystal dimming film with high speed and efficiency, thereby improving the production efficiency of liquid crystal dimming films.
[0013] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:
[0014] In some embodiments, the polishing drive unit is a motor, and two motors are provided. The polishing wheels include a coarse polishing wheel and a fine polishing wheel, with one motor connected to the coarse polishing wheel and the other connected to the fine polishing wheel. The coarse and fine polishing wheels can improve the polishing effect at the edges of the liquid crystal dimming film.
[0015] In some embodiments, a dropper connected to the mounting base is provided above the coarse polishing wheel for applying polishing fluid to the coarse polishing wheel. This can further improve the polishing effect at the edge of the liquid crystal dimming film.
[0016] In some embodiments, the second platform slides laterally with the first platform via guide rails and sliders.
[0017] In some embodiments, the longitudinal drive unit consists of two linear modules arranged longitudinally, and the drive ends of both linear modules are connected to the first platform.
[0018] In some embodiments, the lateral drive unit is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, and its drive end is connected to the second platform.

[0020] In some embodiments, the motor is a continuously variable speed motor.
[0021] In some implementations, the detection unit is an ultrasonic probe or an infrared sensor.
[0022] In some embodiments, the mounting base is provided with a strip-shaped through hole for laterally adjusting the fixed position of the motor. Attached Figure Description
