DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0024] according to Figure 1 , 2 As shown in Figures 3 and 4, a polarizer defoaming auxiliary device is proposed in this embodiment, including a rectangular frame 1, and two roller cleaning members are arranged above the rectangular frame 1; the polarizer to be cleaned passes between the two roller cleaning members, and the roller cleaning members brush the polarizer.
[0025] A top plate 2 is provided at the upper end of the rectangular frame 1, a bottom plate 13 is provided at the lower end of the rectangular frame 1, two second inclined wedge blocks 8 are provided between the top plate 2 and the bottom plate 13, the second inclined wedge blocks 8 are slidably connected with the top plate 2 and the bottom plate 13, a first inclined wedge block 7 is provided between the two second inclined wedge blocks 8, a first inclined surface 71 is provided on the side of the first inclined wedge block 7, and the first inclined surface 71 is slidably connected with a second inclined surface 81 provided on the side of the second inclined wedge block 8;
[0026] The second inclined wedge block 8 is arranged on both sides of the first inclined wedge block 7, and together with the first inclined wedge block 7, forms an inclined wedge mechanism, which works on the principle of inclined plane and is mainly used to transmit force, change the direction of force, and realize the clamping and releasing of objects.
[0027] A pushing assembly is provided on the outside of the rectangular frame 1 for pushing the first inclined wedge block 7 to open the two second inclined wedge blocks 8, and a spring structure is provided on the inside of the rectangular frame 1 for pushing the two second inclined wedge blocks 8 to close. The two second inclined wedge blocks 8 are fixedly connected to the two roller cleaning members respectively.
[0028] The first inclined wedge block 7 is driven by the push assembly to enter between the two second inclined wedge blocks 8. As the first inclined wedge block 7 goes deeper, the positive pressure between the first inclined surface 71 and the second inclined surface 81 increases, and the two second inclined wedge blocks 8 open with the two roller cleaning members, and no longer contact the front and back surfaces of the polarizer. The second inclined wedge block 8 is moved in the opposite direction, and the positive pressure between the first inclined surface 71 and the second inclined surface 81 is reduced. The spring structure pushes the two second inclined wedge blocks 8 to close together, and the two roller cleaning members contact the surface of the polarizer when they close together. Due to the existence of the elastic thrust, the cleaning roller member will not over-exert the polarizer, and the appearance of bubbles can be effectively reduced during the cleaning process.
[0029] For the specific structure of the roller cleaning element, please refer to the following description.
[0030] The roller cleaning member includes a driving motor 3, which is placed above the top plate 2. A fixing frame 9 is provided at the lower end of the driving motor 3, and the fixing frame 9 is fixedly connected to the two ends of the second inclined wedge block 8. A roller shaft 5 is provided at the output end of the driving motor 3, and a cotton sleeve 4 is provided on the outer side of the roller shaft 5. When the polarizer to be cleaned passes between the two roller shafts 5, the cotton sleeve 4 will contact the front and back sides of the polarizer, and the driving motor 3 controls the cotton sleeve 4 to rotate through the roller shaft 5 to clean the surface of the polarizer.
[0031] For the specific structure of the push component, please refer to the following description.
[0032] The push assembly includes an electric push rod 6, the mounting end of the electric push rod 6 is fixedly connected to the outside of the rectangular frame 1, and the output end of the electric push rod 6 penetrates into the rectangular frame 1 and is fixedly connected to the first inclined wedge 7. The horizontal movement of the first inclined wedge 7 is controlled by the electric push rod 6. Of course, in addition to the electric push rod 6, other linear push mechanisms, such as pneumatic push rods, hydraulic push rods, etc., can also be used as substitutes, which will not be described in detail here.
[0033] About the spring assembly:
[0034] The spring structure includes a spring 10, which is fixedly connected to the side of the second inclined wedge block 8 away from the first inclined wedge block 7, and one end of the spring 10 away from the second inclined wedge block 8 is fixedly connected to the inner wall of the rectangular frame 1. The two springs 10 are fixedly connected to the side of the two second inclined wedge blocks 8 away from the first inclined wedge block 7, and under the push of the springs 10, the second inclined surface 81 on the second inclined wedge block 8 will always remain in a state of close contact with the first inclined surface 71 on the first inclined wedge block 7.
[0035] In order to prevent the second inclined wedge block 8 from deflecting when being pushed, a slide rail 12 is provided on the side of the bottom plate 13 close to the second inclined wedge block 8, and the slide rail 12 is fixedly connected to the bottom plate 13. A slider is provided on the bottom plate 13, and the slider is slidably connected to the slide rail 12, and the slider is fixedly connected to the second inclined wedge block 8. When the second inclined wedge block 8 is pushed by the spring 10 or the first inclined wedge block 7, the slider fixed to the second inclined wedge block 8 will slide along the slide rail 12, and the slide rail 12 guides the second inclined wedge block 8 by cooperating with the slider, so that the second inclined wedge block 8 always maintains a horizontal sliding state when being pushed.
[0036] See also Figure 4 A better implementation is that a limiting rod 11 is provided inside the rectangular frame 1, the limiting rod 11 is fixedly connected to the rectangular frame 1, the limiting rod 11 is perpendicular to the bottom plate 13, the limiting rod 11 penetrates the first oblique wedge block 7, and the first oblique wedge block 7 is slidably connected to the limiting rod 11. In addition to limiting the second oblique wedge block 8, the rectangular frame 1 also limits the first oblique wedge block 7 through the limiting rod 11, so that when the first oblique wedge block 7 is pushed, it can move vertically along the rod body of the limiting rod 11 without deviation.
[0037] See also Figure 5 Another better implementation is that the first inclined surface 71 is provided with a guide groove 72, which is integrally formed with the first inclined wedge block 7, and the second inclined surface 81 is provided with a limit groove 82, and the first inclined surface 71 is inserted into the limit groove 82 and slidably connected with the limit groove 82. When the first inclined wedge block 7 is pushed, the first inclined surfaces 71 on both sides of the first inclined wedge block 7 will slide along the limit groove 82 on the second inclined surface 81, and the limit groove 82 guides the first inclined wedge block 7 by cooperating with the first inclined surface 71, so that the first inclined wedge block 7 will not deviate when being pushed.
[0038] The working principle of the present application is as follows: the polarizer to be cleaned passes between two roller cleaning members, and the roller cleaning members scrub the polarizer.
[0039] The first inclined wedge block 7 is driven by the push assembly to enter between the two second inclined wedge blocks 8. As the first inclined wedge block 7 goes deeper, the positive pressure between the first inclined surface 71 and the second inclined surface 81 increases, and the two second inclined wedge blocks 8 open with the two roller cleaning members, and no longer contact the front and back surfaces of the polarizer. The second inclined wedge block 8 is moved in the opposite direction, and the positive pressure between the first inclined surface 71 and the second inclined surface 81 is reduced. The spring structure pushes the two second inclined wedge blocks 8 to close together, and the two roller cleaning members contact the surface of the polarizer when they close together. Due to the existence of the elastic thrust, the cleaning roller member will not over-exert the polarizer, and the appearance of bubbles can be effectively reduced during the cleaning process.
