At this time, the slider 15 slides in the slide groove 14 to drive the grinding wheel 16 to move at the same time, so that the edges around the LCD screen can be polished. In this step, by setting the slider 15 to slide in the slide groove 14 and drive the grinding wheel 16 to move at the same time, the edges around the LCD screen placed on the top of the fixed table 11 can be polished, so as to reduce the need to frequently adjust the position of the LCD screen when grinding the edge of the LCD screen, so as to improve the convenience during grinding.
[0025] like Figure 1 and Figure 2 As shown, the fixing assembly includes a first fixing plate 2; the first fixing plate 2 is fixedly connected to the side wall of the fixing frame 13; an electric push rod 21 is fixedly connected to the bottom of the first fixing plate 2; a second fixing plate 22 is fixedly connected to the end of the electric push rod 21; during operation, when the LCD screen is placed on the top of the fixing table 11, the electric push rod 21 is started to move downward to drive the second fixing plate 22 to move at the same time, and when the second fixing plate 22 contacts the LCD screen placed on the top of the fixing table 11, the LCD screen can be pressed to fix the position of the LCD screen. In this step, the electric push rod 21 is set to drive the second fixing plate 22 to move and press the LCD screen to fix the position of the LCD screen, so as to reduce the situation where the grinding wheel 16 moves the position of the LCD screen when grinding the LCD screen, resulting in uneven grinding, so as to improve the effect of grinding the edge of the LCD screen.
[0026] like Figure 2 As shown, a plurality of spring rods 3 are provided in the middle of the second fixing plate 22; a third fixing plate 31 is fixedly connected to the end of the spring rod 3; during operation, when the electric push rod 21 drives the second fixing plate 22 to contact the LCD screen, the third fixing plate 31 located below the second fixing plate 22 will contact the LCD screen, and at this time, the plurality of spring rods 3 will contract to reduce the impact force generated when the third fixing plate 31 contacts the LCD screen, and the position of the LCD screen can be fixed at the same time. In this step, the spring rods 3 are arranged to connect the third fixing plate 31 and the second fixing plate 22, so that the spring rods 3 are contracted when the third fixing plate 31 contacts the LCD screen, and the third fixing plate 31 is driven to move toward the second fixing plate 22 to reduce the impact force generated when the third fixing plate 31 contacts the LCD screen, which may cause damage to the LCD screen, thereby playing a protective role.
[0027] like Figure 1 As shown, a plurality of collecting holes 4 are provided in the middle of the operating table 1; a collecting box 41 is fixedly connected to the bottom of the operating table 1; the collecting box 41 is hollow; during operation, when the grinding wheel 16 grinds the edge of the LCD screen, more debris will be generated, and the debris will fall to the top of the operating table 1. At this time, part of the debris will fall from the collecting holes 4 on the top of the operating table 1 into the collecting box 41 below, and the collecting box 41 can collect the falling debris. In this step, the collecting holes 4 and the collecting box 41 are set to collect the debris generated when grinding the edge of the LCD screen, so as to reduce the situation where the debris remains on the top of the operating table 1 and causes pollution and corrosion to the top of the operating table 1, and at the same time, it can reduce the situation where the debris adheres to the surface of the LCD screen and affects the grinding effect.
[0028] like Figure 1As shown, a pull-out box 5 is provided in the collection box 41; the pull-out box 5 is slidably matched with the collection box 41; during operation, when the debris generated during grinding falls into the collection box 41, the pull-out box 5 is located in the collection box 41, so that the debris can enter the pull-out box 5 and be collected. When the collection is completed, the pull-out box 5 can be pulled out of the collection box 41 to pour out the debris, and then the pull-out box 5 can be put back into the collection box 41. In this step, the pull-out box 5 is arranged to be located in the collection box 41 to collect the fallen debris.

[0031] Working principle: during operation, when grinding the edge of the LCD screen, the LCD screen is placed on the surface of the fixed platform 11 and then the fixing component is started to fix it, so that the edge of the LCD screen contacts the grinding wheel 16 and then the grinding wheel 16 is started to grind the edge of the LCD screen. At this time, the slider 15 slides in the slide groove 14 to drive the grinding wheel 16 to move at the same time, and the edges around the LCD screen can be polished. After the LCD screen is placed on the top of the fixed platform 11, the electric push rod 21 is started to move downward to drive the second fixed plate 22 to move at the same time. When the second fixed plate 22 contacts the LCD screen placed on the top of the fixed platform 11, the LCD screen can be pressed to fix the position of the LCD screen. When the electric push rod 21 drives the second fixed plate 22 to contact the LCD screen, the third fixed plate 31 located below the second fixed plate 22 will contact the LCD screen. At this time, multiple spring rods 3 will shrink to reduce the impact force generated when the third fixed plate 31 contacts the LCD screen, and the position of the LCD screen can be fixed at the same time. When the grinding wheel 16 grinds the edge of the LCD screen, a lot of debris will be generated, and the debris will fall to the top of the operating table 1. At this time, part of the debris will fall from the collection hole 4 on the top of the operating table 1 into the collection box 41 below. At this time, the collection box 41 can collect the falling debris. When the debris generated during grinding falls into the collection box 41, the pull-out box 5 is located in the collection box 41, allowing the debris to enter the pull-out box 5 and be collected. When the collection is completed, the pull-out box 5 can be pulled out of the collection box 41. The debris is poured out, and then the pull-out box 5 is put back into the collection box 41. During polishing, the air pump 6 can be started to drive the air flow into the air outlet pipe 61, and then flow out from the air outlet 62 at the bottom of the air outlet pipe 61. The air flow will blow toward the surface of the LCD screen when flowing downward, and the generated debris can be blown off and the polishing position can be cooled. When the LCD screen is placed on the top of the fixing table 11 and fixed, the suction cup 7 is located on the top of the fixing table 11 and will contact the LCD screen. At this time, the suction cup 7 will be adsorbed on the surface of the LCD screen.
