[0036] The present application discloses a polarizing film cleaning machine, referring to Figure 1 and Figure 2 The polarizer cleaning film machine includes a bracket 1 and a conveyor belt 4. The bracket 1 includes four legs 11 and two parallel mounting plates 12. The legs 11 are arranged in a vertical direction, and the two ends of the mounting plate 12 are fixedly connected to the two legs 11. The conveyor belt 4 includes a first driving member 41, a plurality of belts 43, and two supporting rollers 42 arranged in sequence along the length direction of the mounting plate 12. The supporting roller 42 is arranged between the two mounting plates 12. The two ends of the supporting roller 42 are rotatably connected to the two mounting plates 12, so that the axis of the supporting roller 42 is arranged in a horizontal direction and perpendicular to the length direction of the mounting plate 12. The plurality of belts 43 are arranged at intervals along the axis direction of the supporting roller 42. The belts 43 are wound around the two supporting rollers 42, and a clearance gap 44 is formed between adjacent belts 43, so that the conveying direction of the conveyor belt 4 is parallel to the length direction of the mounting plate 12. The first driving member 41 is a motor, the first driving member 41 is installed on the mounting plate 12, and the output end of the first driving member 41 is coaxially fixedly connected to the supporting roller 42.

[0037] Reference Figure 1 and Figure 2A polarizer cleaning film feeding machine includes a dust sticking assembly 5, which includes a first dust sticking roller 51, a guide portion 54, a second driving member 53 and a plurality of second dust sticking rollers 52. The first dust sticking roller 51 is rotatably connected to the top of the conveyor belt 4, and the rotation axis of the first dust sticking roller 51 is arranged in the horizontal direction and perpendicular to the conveying direction of the conveyor belt 4. The first dust sticking roller 51 and the guide portion 54 are arranged in sequence along the conveying direction of the conveyor belt 4, and the guide portion 54 is in the shape of a long strip, and the guide portion 54 is arranged in the horizontal direction and inclined to the conveying direction of the conveyor belt 4. One end of the guide portion 54 is fixedly connected to a mounting plate 12, and the distance between the connection between the guide portion 54 and the mounting plate 12 and the first dust sticking roller 51 is smaller than the distance between the other end of the guide portion 54 and the first dust sticking roller 51. A plurality of second dust-sticking rollers 52 are arranged below the guide portion 54 along the conveying direction of the conveyor belt 4. The second dust-sticking rollers 52 include a rotating shaft 521 and a plurality of dust-sticking portions 522. The axis of the rotating shaft 521 is arranged in the horizontal direction and is perpendicular to the conveying direction of the conveyor belt 4. The dust-sticking portion 522 is cylindrical with an outer diameter greater than the outer diameter of the rotating shaft 521. The plurality of dust-sticking portions 522 are fixedly connected to the rotating shaft 521 at intervals along the axis direction of the rotating shaft 521. The dust-sticking portions 522 protrude from the top surface of the belt 43 in the clearance gap 44. The second driving member 53 is a transmission structure composed of a motor, a belt and a plurality of pulleys. The pulley is coaxially fixedly connected to one end of the rotating shaft 521. The belt is sequentially wound around the output end of the motor and the plurality of pulleys, so that the motor can simultaneously drive the plurality of pulleys to rotate through the belt.

[0038] In other embodiments of the present application, a motor may be installed on the mounting plate 12, and an output end of the motor is coaxially fixedly connected to the first dust-sticking roller 51, so that the first dust-sticking roller 51 is driven to rotate by the motor.

[0039] The conveyor belt 4 is used to convey the polarizer, so that the polarizer passes through the first sticky roller 51 and multiple second sticky rollers 52 in sequence. When the polarizer passes through the first sticky roller 51, the first sticky roller 51 abuts against the top wall of the polarizer, thereby cleaning the dust on the top wall of the polarizer. Then the polarizer moves with the conveyor belt 4 to abut against the sticky part 522 of the second sticky roller 52, and moves along the guide part 54. When the polarizer moves along the guide part 54, since the moving direction of the polarizer is inclined to the conveying direction of the conveyor belt 4, different positions of the bottom wall of the polarizer abut against the multiple sticky parts 522 in sequence, so that the sticky parts 522 clean the dust on the bottom wall of the polarizer, thereby achieving the cleaning of the top and bottom walls of the polarizer, and improving the cleaning effect of the polarizer.

[0040] Reference Figure 1 and Figure 2A tensioning roller 2 is arranged between the first dust-sticking roller 51 and the second dust-sticking roller 52, and a belt 43 is wound around the tensioning roller 2. Both ends of the tensioning roller 2 are rotatably connected to two mounting plates 12 respectively. The rotation axis of the tensioning roller 2 is parallel to the rotation axis of the supporting roller 42, and the outer diameter of the tensioning roller 2 is larger than the outer diameter of the supporting roller 42.

[0041] The outer diameter of the tensioning roller 2 is greater than the outer diameter of the supporting roller 42 , thereby tensioning the belt 43 of the conveyor belt 4 , reducing the deviation of the belt 43 , and improving the running stability of the conveyor belt 4 .

[0042] Reference Figure 1 and Figure 2 A polarizing film cleaning machine includes two ion wind rods 3, one ion wind rod 3 is installed on the mounting plate 12 between the first sticky roller 51 and the second sticky roller 52, and is located above the belt 43, and the other ion wind rod 3 is arranged on the mounting plate 12 on the side of the second sticky roller 52 away from the first sticky roller 51, and is located below the belt 43.

[0043] When the polarizer passes through the first dust-adhering roller 51 and moves to the ion wind rod 3, the ion wind rod 3 blows air masses with corresponding charges to the top wall of the polarizer to neutralize the static electricity of the polarizer. When the polarizer moves to the separation guide 54, the polarizer abuts against the belt 43 again, and the ion wind rod 3 under the belt 43 blows air masses with corresponding charges to the bottom wall of the polarizer to neutralize the static electricity of the polarizer again, thereby reducing dust attached to the polarizer due to static electricity.

[0044] Reference Figure 2 and Figure 3 A polarizer cleaning film machine includes a dust collecting assembly 6, which includes a dust collecting box 61, a brush 62 and a dust collector 63. The dust collecting box 61 is arranged between two mounting plates 12, and the dust collecting box 61 is fixedly connected to the mounting plates 12. Two brushes 62 are rotatably connected to the dust collecting box 61 through bearings. The two brushes 62 are arranged in a vertical direction, and the rotation axis of the brush 62 is parallel to the rotation axis of the support roller 42. The brush 62 is cylindrical, and the output end of the dust collector 63 is arranged inside the dust collecting box 61. The belt 43 at the bottom of the conveyor belt 4 passes through the dust collecting box 61, and the belt 43 inside the dust collecting box 61 is located between the two brushes 62.

[0045] After conveying the polarizer, the belt 43 enters the dust box 61 and passes through the upper and lower brushes 62. The two brushes 62 clean the dust attached to the belt 43. At the same time, the dust collector 63 sucks away the dust inside the dust box 61. Then the belt 43 passes through the dust box 61, thereby reducing the dust attached to the belt 43 from contaminating the polarizer. The dust box 61 can reduce the dust that escapes to the external environment, and the dust collector 63 can reduce the dust in the dust box 61 from attaching to the belt 43 again.

[0046] The implementation principle of a polarizer cleaning machine in the embodiment of the present application is as follows: the polarizer is transported by the conveyor belt 4, so that the polarizer passes through the first dust-sticking roller 51 and the second dust-sticking roller 52 in sequence. When the polarizer passes through the first dust-sticking roller 51, the first dust-sticking roller 51 abuts against the top surface of the polarizer, thereby cleaning the dust on the top surface of the polarizer. After the polarizer passes through the first dust-sticking roller 51, the polarizer moves with the conveyor belt 4 to abut against the guide part 54 and moves along the guide part 54. At the same time, the polarizer abutting against the guide part 54 is lifted up by the dust-sticking part 522. Since the moving direction of the polarizer is inclined to the conveying direction of the conveyor belt 4 at this time, different positions of the bottom wall of the polarizer pass through the dust-sticking part 522 in sequence, and the dust-sticking part 522 cleans the bottom wall of the polarizer, so that both the top wall and the bottom wall of the polarizer can be cleaned to improve the cleaning effect of the polarizer.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
