[0028] Among them, in order to achieve the purpose of grinding the edge of the backlight source panel, the present device is implemented by the following technical scheme: the moving component includes a moving block 12, the moving block 12 is arranged on the outside of the threaded rod 7 and is threadedly connected to the threaded rod 7, the two moving blocks 12 have opposite thread directions, the top of the moving block 12 is fixedly connected to a frame 13, an electric screw 14 is arranged inside the frame 13, a sliding block 15 is arranged outside the electric screw 14, the sliding block 15 is connected to the electric screw 14 through a ball screw pair, one side of the sliding block 15 is fixedly connected to a connecting frame 16, a rotating rod is arranged inside the connecting frame 16, the top of the rotating rod passes through the top of the connecting frame 16 and is connected to the connecting frame 16 through a bearing, the top of the rotating rod is fixedly connected to a motor, a grinding cylinder 17 is fixedly sleeved on the outside of the rotating rod, a stabilizing groove is opened on the inner wall of the frame 13, a stabilizing block 18 is embedded in the stabilizing groove, the stabilizing block 18 is slidably connected to the stabilizing groove, and one side of the stabilizing block 18 is fixedly connected to one side of the sliding block 15;

[0029] Among them, in order to achieve the purpose of conveniently adjusting the position of the backlight panel, the present device is implemented by the following technical scheme: the rotating component includes a rotating rod 19, the top of the rotating rod 19 is fixedly connected to the bottom of the circular plate 5, the bottom of the table 1 is fixedly connected to an L-shaped plate, the top of the L-shaped plate is provided with a connecting rod 20, the connecting rod 20 is connected to the L-shaped plate through a bearing, the top of the connecting rod 20 is fixedly connected to a handwheel, the outer sides of the rotating rod 19 and the connecting rod 20 are fixedly sleeved with synchronous wheels 21, the outer sides of the two synchronous wheels 21 are sleeved with synchronous belts 22, the two synchronous wheels 21 are driven and connected by the synchronous belts 22, a limiting groove 23 is provided on the top of the table 1, the limiting groove 23 is provided on the rear side of the circular plate 5, two limiting blocks are embedded in the limiting groove 23, the two limiting blocks are slidably connected to the limiting groove 23, the tops of the two limiting blocks are respectively fixedly connected to the bottoms of the two frames 13, and the four corners of the bottom of the table 1 are fixedly connected with support columns 24.

[0030] The use process of the utility model is as follows: first, the backlight panel is placed on the circular plate 5, and then the electric cylinder 4 is started. The electric cylinder 4 works to drive the connecting plate 8 to move. The movement of the connecting plate 8 will drive the telescopic rod 10 and the spring 11 to move. The movement of the telescopic rod 10 will cause the pressure plate 9 and the cushion to move. When the cushion contacts the backlight panel, under the action of the telescopic rod 10 and the spring 11, the electric cylinder 4 can still be extended, and the spring 11 will be compressed and the telescopic rod 10 will also shrink.

The movement of the sliding block 15 drives the connecting frame 16, the rotating rod, the motor and the grinding cylinder 17 to move. When the grinding cylinder 17 contacts the edge of the backlight source panel, the motor and the electric screw 14 are started. The motor works to rotate the rotating rod and the grinding cylinder 17 is rotated through the rotating rod. At the same time, the rotation of the electric screw 14 will cause the sliding block 15 to reciprocate back and forth on the electric screw 14, so that the grinding cylinder 17 can grind the edge of the backlight source panel. When it is necessary to change the edge, first rotate the threaded rod 7 so that the grinding cylinder 17 does not contact the backlight source panel, and then start the electric cylinder 4 again so that the pressure plate 9 and the soft pad do not contact the backlight source panel, and then turn the hand wheel to rotate the connecting rod 20. The rotation of the connecting rod 20 will rotate the rotating rod 19 through the synchronous wheel 21 and the synchronous belt 22. The rotation of the rotating rod 19 will cause the circular plate 5 to rotate. The rotation of the circular plate 5 can adjust the backlight source panel.
