[0002] The POL polarizing sheet is one of three key components of a liquid crystal display, is a composite material made of a polyvinyl alcohol film (PVA) stretched and a triacetate cellulose film (TAC) compounded, and can realize high brightness and high contrast characteristics of the liquid crystal display. The polarizing sheet needs to be cleaned and dusted during production.

[0003] The prior art CN207971169U discloses a polarizing sheet dust removing device, which comprises a frame, a conveying belt arranged on the frame, and a first rubber wheel arranged at a middle position of the frame. The first rubber wheel is arranged in two parts, i.e., an upper part and a lower part. The first rubber wheel is respectively tangent to a second rubber wheel with a higher viscosity than the first rubber wheel. The upper and lower first rubber wheels are used for double-sided dust removal. The second rubber wheel tangent to the first rubber wheel and having a higher viscosity than the first rubber wheel is used to carry away dust, thereby realizing efficient dust removal of the polarizing sheet and good protection of the polarizing sheet.

[0004] However, the above-mentioned patent can only remove dust from the front and back surfaces of the polarizing sheet, and cannot remove dust from the four side edges of the polarizing sheet. At present, the research on dust removal of the polarizing sheet is only for the front and back surfaces of the polarizing sheet, and there is no device for dust removal of the four side edges of the polarizing sheet. Therefore, manual dust removal is currently used for the side edges of the polarizing sheet. During dust removal, the work staff places the transfer paper on the table top, and then manually takes the polarizing sheet to sequentially attach the four side edges of the polarizing sheet to the transfer paper. The dust on the side edges of the polarizing sheet is stuck to the transfer paper. This manual dust sticking and cleaning method of the polarizing sheet has high labor intensity of the work staff and low efficiency. SUMMARY
