Technical Field

[0001] The utility model relates to the technical field of polaroid processing equipment and discloses a polaroid edge grinding device. Background Art

[0002] Polarizer edging refers to the process of edge processing of polarizers during the manufacturing process of liquid crystal displays (LCDs). Polarizers are an important component of LCD screens, which can control the direction of light transmission to achieve image display.

[0003] During the LCD panel production process, polarizers need to be precisely attached to the glass substrate. To achieve this, edge grinding equipment is required to ensure the flatness and precision of the polarizer edges, avoiding any impact on the display or other quality issues. However, in actual use, some edge grinding equipment lacks a positioning mechanism, making precise positioning impossible.

The two support bases 1 are connected together by bolts to form an edge grinding box 2. The front side of the edge grinding box 2 is rotatably provided with a protective door 3, and the handle 4 is fixedly connected to the protective door 3. The interior of the edge grinding box 2 is fixedly connected with a fixed plate 6, and the interior of the edge grinding box 2 is provided with a limit frame 12 by bolts. The rear side of the limit frame 12 is provided with an electric push rod Ⅰ 13 by means of bolt connection, and a pressure plate 14 is slidably provided on the limit frame 12. The telescopic rod of the electric push rod Ⅰ 13 is connected to the pressure plate 14. The top of the edge grinding box 2 is provided with an electric slide 15 by means of bolt connection, and an electric push rod Ⅱ 16 is provided on the electric slide 15 by means of bolt connection. The telescopic rod of the electric push rod Ⅱ 16 is connected with a grinding component 17. By setting different parameters for the grinding component 17, it can adapt to the grinding of polarizers of different thicknesses. An angle adjustment mechanism is provided inside the edge box 2, a placement plate 7 is rotatably provided on the fixed plate 6, a rotating shaft 8 is fixedly connected to the bottom of the placement plate 7, a drive motor 9 is provided in the edge grinding box 2 by means of bolt connection, the output shaft of the drive motor 9 is connected to a worm 10 through a coupling, a worm gear 11 is fixedly connected to the rotating shaft 8, the worm gear 11 is meshed with the worm 10, a scanner 18 is provided on the rear side of the edge grinding box 2 by means of bolt connection, a controller 19 is provided on the scanner 18, and the controller 19 is connected to the signal of the electric slide 15 The handle 4 is connected, and a protective cover 5 is provided on the protective cover 5. The protective cover 5 is provided with concave and convex patterns to increase the friction between the hand and the handle 4, thereby preventing the hand from slipping. A protective shell 20 is provided on the rear side of the edge grinding box 2, and the scanner 18 and the controller 19 are both located inside the protective shell 20, thereby protecting the scanner 18 and the controller 19, thereby preventing debris from entering the scanner 18 and the controller 19 during grinding. A buffer pad 30 is embedded in the bottom of the pressure plate 14, which will not cause damage or wear to the polarizer when pressed.

[0025] When it is necessary to edge the polarizer, hold the handle 4 and turn the protective door 3 outward to open the edge grinding box 2, place the polarizer on the placement plate 7, and then turn on the electric push rod Ⅰ13 to control the telescopic rod of the electric push rod Ⅰ13 to retract, so that the pressure plate 14 moves downward along the limit frame 12 and contacts the polarizer, thereby pressing and fixing the polarizer. Subsequently, turn on the scanner 18, and the scanner 18 scans the polarizer. The controller 19 starts the electric slide 15 according to the position parameter information scanned by the scanner 18, so that the electric push rod Ⅱ16 drives the grinding assembly 17 to move to the appropriate position above the polarizer, thereby achieving precise positioning, enhancing the degree of automation of the equipment, and improving the grinding efficiency. After the grinding assembly 17 moves to the appropriate position above the polarizer, turn on the electric push rod Ⅱ16 and the grinding assembly 17. Component 17 controls the extension of the telescopic rod of the electric push rod II 16, so that the grinding component 17 contacts the edge of the polarizer, so that the grinding component 17 grinds the polarizer. After the multiple sides of the polarizer are polished, the telescopic rod of the electric push rod I 13 is controlled to extend, so that the pressure plate 14 no longer presses and fixes the polarizer, and then the drive motor 9 is started. The output shaft of the drive motor 9 rotates to drive the worm 10 to rotate. Under the meshing action of the worm 10 and the worm gear 11, the worm gear 11 also rotates, so that the rotating shaft 8 drives the placement plate 7 to rotate, and then the angle of the polarizer is adjusted. After the adjustment is completed, the telescopic rod of the electric push rod I 13 is controlled to retract, so that the pressure plate 14 presses and fixes the polarizer again, so that the polarizer can continue to be polished without adjusting the position of the grinding component 17, thereby improving the polishing efficiency.

[0027] After placing the polarizer on the placement plate 7, start the electric slide rail 22, so that the electric slider 23 drives the clamping plate 24 to move inward, so that the clamping plate 24 adjusts the polarizer left and right. At the same time, turn on the motor 25, and the drive shaft of the motor 25 rotates to drive the screw 26, and the screw 26 drives the adjustment plate 27 to move inward, so that the adjustment plate 27 adjusts the polarizer front and back, thereby making the polarizer located in the center position of the placement plate 7, thereby avoiding the position offset of the polarizer affecting the polishing effect.
