[0002] A polarizer, full name polarization light sheet, is one of the imaging components of a liquid crystal display. The basic structure of a polarizer includes PVA (polyvinyl alcohol) in the middle, two layers of TAC (triacetyl cellulose), PSA film (pressure-sensitive adhesive), Release film (release film), and Protective film (protective film). There are absorption polarizers and reflection polarizers, which have the characteristics of good flexibility, lightness, and unrestricted area.

[0003] According to a protective film appearance defect detection device with the publication number CN216386841U, including a base, a detection box is installed on the top of the base.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] The present invention provides technical solutions as follows: As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, in this embodiment, a polarizer surface trace detection device includes an external box 1. Inside the external box 1, there is a polarizer film 2. The polarizer film 2 moves inside the external box 1 through an external conveying roller. There is also a light 1 3 and a light 2 4 arranged inside the external box 1 for illuminating the polarizer film 2, and a light spot induction device 5 arranged inside the external box 1 for detecting the polarizer film 2. There is an internal box 6 fixedly arranged inside the external box 1. The polarizer film 2 moves inside the internal box 6. A cleaning mechanism 7 is arranged inside the internal box 6 to wipe the surface of the moving polarizer film 2. A fixing member 8 is fixedly arranged inside the internal box 6 to fix the position of the cleaning mechanism 7. A driving member 9 is arranged inside the internal box 6 to move the cleaning mechanism 7 in position. A dust suction member 10 is arranged on one side of the cleaning mechanism 7 to absorb the raised dust. The light 1 3 is located on one side of the polarizer film 2, the light 2 4 is located directly below the polarizer film 2, and the light spot induction device 5 is located above the polarizer film 2 and the light 2 4 to effectively irradiate the polarizer film 2 for subsequent trace detection work. As the polarizer film 2 moves inside the external box 1 and the internal box 6, during the lighting of the light 1 3 and the light 2 4 and the detection by the light spot induction device 5, with the driving of the driving member 9, the cleaning mechanism 7 works inside the internal box 6, that is, the square plate 75 drives the sponge strip 76 to descend, so that the sponge strip 76 wipes and cleans the dust on the surface of the polarizer film 2. And the provided dust suction member 10 can absorb and transfer the raised dust to prevent secondary adhesion on the surface of the polarizer film 2. This structure can clean the dust before trace detection, thereby improving the detection effect of high-definition traces. The light spot induction device 5 in this article is the same as the light spot induction device 10 in the disclosed component cited in the specification.

[0030] As Figure 2 , Figure 3 and Figure 4As shown, the cleaning mechanism 7 includes a support box 71, a slider 72 and a slide shaft 73 are inserted in the support box 71, the slider 72 slides on the outside of the slide shaft 73, a spring 74 is sleeved on the outside of the slide shaft 73, and the two ends of the spring 74 respectively contact the outside of the slider 72 and the inside of the support box 71, one end of the slider 72 is fixedly connected to a square plate 75, a sponge strip 76 is arranged below the square plate 75, a T-slot 78 is opened on the lower surface of the square plate 75, a T-block 79 is inserted in the T-slot 78, and the T-block 79 is fixedly installed on the upper surface of the sponge strip 76, the outer box 1 An external hole 13 is opened on the outside, and a door panel 14 is rotatably connected to the external hole 13 through a hinge. The door panel 14 is located at one side of the cleaning mechanism 7, and is provided with a T-slot 78 and a T-block 79 to facilitate personnel to remove and install the sponge strip 76. Through this structure, the column 77 is subsequently driven by the driving member 9 to squeeze the square plate 75 downward, so that the sponge strip 76 can be in contact with the upper surface of the polarizer film 2 to wipe and clean the dust on the surface of the polarizer film 2. In addition, this structure can replace the sponge strip 76 without stopping the machine.

[0031] like Figure 2 and Figure 3 As shown, the fixing member 8 includes a fixing column 81, and the fixing column 81 is fixedly installed on the inner wall of the built-in box 6. A V-shaped plate 82 is fixedly installed on the bottom end of the fixing column 81, and the V-shaped plate 82 is fixedly installed on the outer side of the support box 71. A connecting rod 83 is fixedly installed on the outer side of the V-shaped plate 82, and the connecting rod 83 is fixedly installed on the outer side of the support box 71. Through this structure, the position of the cleaning mechanism 7 can be effectively fixed.

[0032] like Figure 2 and Figure 3 As shown, the driving member 9 includes a servo motor 91, which is fixedly installed on the upper surface of the built-in box 6. A rotating shaft 92 is fixedly connected to the rotating shaft of the servo motor 91. A toggle rod 93 is fixedly provided on the outer side of the rotating shaft 92. One side of the toggle rod 93 abuts against the top of the column 77. Through this structure, as the servo motor 91 drives the rotating shaft 92 to rotate, the toggle rod 93 can push the column 77 to move downward.

[0033] like Figure 1 and Figure 2 As shown, the dust collecting member 10 includes an internal tube 11, which is located at one side of the cleaning mechanism 7. An external tube 12 is fixedly installed on the outside of the internal tube 11, and the other end of the external tube 12 is connected to an external vacuum pump. Through the cooperation between the internal tube 11 and the external tube 12, the raised dust can be effectively absorbed and transferred.

[0034] likeFigure 5 As shown, a cylinder 15 is fixedly installed on the outside of the external box 1. The telescopic end of the cylinder 15 is fixedly connected to a box body 16. The top end of the box body 16 is fixedly connected to a hose 17, and the hose 17 is connected to an external feeding pump. A sponge block 18 is fixedly installed on the box body 16, and the sponge block 18 is located on one side of the polarizing film 2.

[0036] During the use of this device, as the polarizing film 2 moves in the external box 1 and the internal box 6, driven by the servo motor 91, the rotating shaft 92 drives the toggle rod 93 to rotate. Thus, the toggle rod 93 presses down on the top end of the square plate 75, causing the column 77 to drive the square plate 75 to descend, so that the sponge strip 76 wipes the dust on the surface of the polarizing film 2. During this period, the slider 72 slides on the outside of the sliding shaft 73 and the spring 74 is in a tightened state. Then, the air pump pumps air into the external pipe 12, so that the internal pipe 11 absorbs the dust raised on one side of the sponge strip 76. Then, the light one 3 and the light two 4 emit light, and the light spot induction device 5 detects the polarizing film 2. During this period, the cylinder 15 drives the box body 16 to move, so that the sponge block 18 after absorbing the color can gently touch the outside of the polarizing film 2, thus playing a role of trace marking to facilitate the subsequent search work for personnel.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
