[0015] The present invention has the following beneficial effects: (1) The present invention places the polarizer body on the top of the carrier, starts the electric telescopic rod, and drives the square plate to move. At the same time, the motor is started, and the motor drives the rotating shaft to rotate. The rotating shaft drives the milling disk to rotate. The square plate drives the motor to move. The motor drives the rotating shaft to move. The rotating shaft drives the milling disk to move. During the movement of the milling disk, the top of the polarizer body can be contacted, so as to grind the polarizer body. When the square plate moves toward the electric telescopic rod, the square plate drives the rotating plate to move. The rotating plate is limited by the vertical rod, and the lifting plate drives the lifting plate to move along the vertical rod. The outer wall moves upward vertically, and the lifting plate drives the bending bar to move upward. During the upward movement of the bending bar, it will contact the bottom protrusion of the ring, so that the ring moves upward along the outer wall of the circular shell, and the ring drives the bending rod to move upward, the bending rod drives the bearing shell to move upward, the bearing shell drives the sliding plate to move upward, the sliding plate drives the bearing frame to move upward, and the bearing frame drives the polarizer body to move upward, thereby further moving the polarizer body upward, improving the fitting effect between the polarizer body and the milling disk, preventing the milling disk from failing to contact the top of the polarizer body during the reciprocating movement and grinding process, and improving the grinding effect of the milling disk from the side.

[0016] (2) In the present invention, when the carrier drives the polarizer body to move upward, it is subjected to the reaction force of the milling disk, causing the polarizer body to move downward, and the polarizer body drives the carrier to move downward, and the carrier drives the sliding plate to enter the interior of the carrier shell to prevent the carrier shell from moving upward excessively, which would cause the milling disk to over-grind the polarizer body, thereby improving the grinding effect of the milling disk. When the carrier moves toward the interior of the carrier shell, the rotating bar is subjected to the downward pressure of the carrier, causing the rotating bar to rotate, and subjected to the limiting groove provided at the bottom of the carrier, the rotating bar drives the first sliding block to slide along the inner wall of the limiting groove, the first sliding block drives the cross bar to move, and the cross bar drives the flexible card plate to move, and the two flexible card plates move closer to each other, thereby clamping the two sides of the polarizer body, preventing the polarizer body from being offset when being ground, improving the grinding stability, and thereby improving the grinding effect of the milling disk.

[0017] (3) In the present invention, when the collar moves upward, the collar drives the rotating rod to move. Due to the setting of the slide groove, the rotating rod drives the second slider to slide along the inner wall of the slide groove. The second slider drives the connecting frame to move. The connecting frame drives the clamping plate to move. The two clamping plates move closer to each other. During the movement of the clamping plate, the side wall of the flexible cardboard will come into contact with the side wall of the flexible cardboard, pushing the side wall of the flexible cardboard to prevent the top of the flexible cardboard from warping when the flexible cardboard clamps the polarizer body, further improving the clamping effect of the flexible cardboard on the polarizer body, and improving the grinding effect of the milling disk on the polarizer body. When the electric telescopic rod moves in the opposite direction, the lifting and lowering The plate moves downward, and the lifting plate no longer squeezes the ring. At this time, the polarizer body's own gravity and the elastic deformation of the second spring cause the bearing shell to vertically descend along the inner wall of the circular shell. During the downward movement of the bearing shell, the airflow inside the circular shell enters the inside of the bent pipe, and the airflow enters the inside of the annular shell through the bent pipe, and the airflow is discharged to the outside through the annular shell. At this time, the polarizer body is falling and is sprayed by the airflow, so that the powder generated by grinding the top of the polarizer body is sprayed off, preventing the powder from adhering to the top of the polarizer body and affecting the subsequent repeated grinding of the polarizer body by the milling disk, thereby improving the grinding effect of the milling disk on the polarizer body.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 3 A clamping assembly 67 is provided at the bottom of the collar 656. The clamping assembly 67 includes a rotating rod 671 rotatably connected to both sides of the bottom of the collar 656. Slide grooves 672 are respectively provided on both sides of the top of the workbench 1. The bottom end of the rotating rod 671 is rotatably connected to a second slider 673. The outer wall of the bottom end of the second slider 673 is slidably connected to the inner wall of the slide groove 672. The second slider 673 is fixedly connected to a connecting frame 674 near the top of the rotating rod 671. The end of the connecting frame 674 away from the second slider 673 is fixedly connected to a clamping plate 675. When the collar 656 moves up, the collar 656 drives the rotating rod 671 to move. Affected by the setting of the slide groove 672, the rotating rod 6 71 drives the second slider 673 to slide along the inner wall of the slide groove 672, the second slider 673 drives the connecting frame 674 to move, the connecting frame 674 drives the clamping plate 675 to move, the two clamping plates 675 approach each other, and the clamping plate 675 will contact with the side wall of the flexible card board 669 during the movement, and push the side wall of the flexible card board 669 to prevent the top of the flexible card board 669 from warping when the flexible card board 669 clamps the polarizer body 6610, thereby further improving the clamping effect of the flexible card board 669 on the polarizer body 6610, and the grinding effect of the milling disk 63 on the polarizer body 6610 is improved.

[0032] The inner wall of the circular shell 64 is provided with a cleaning assembly 68, which includes a curved pipe 681 connected to one side of the bottom end of the inner wall of the circular shell 64, one end of the curved pipe 681 passes through the collar 656 and extends to the outside of the collar 656, and the end of the curved pipe 681 away from the circular shell 64 is connected to the annular shell 682, and the bottom of the annular shell 682 is fixedly connected to the top of the circular shell 64. When the electric telescopic rod 4 moves in the reverse direction, the lifting plate 653 moves downward, and the lifting plate 653 no longer squeezes the collar 656. At this time, the self-gravity of the polarizer body 6610 and the elastic deformation of the second spring 659 cause the bearing shell 658 to move along the circular shell 64. The inner wall of the shell 64 descends vertically, and during the downward movement of the supporting shell 658, the airflow inside the circular shell 64 enters into the interior of the curved pipe 681, and then enters into the interior of the annular shell 682 through the curved pipe 681, and then is discharged to the outside through the annular shell 682. At this time, the polarizer body 6610 is sprayed by the airflow during its falling process, so that the powder produced by grinding the top of the polarizer body 6610 is sprayed off, and the powder is prevented from adhering to the top of the polarizer body 6610, which affects the subsequent repeated grinding of the polarizer body 6610 by the milling disk 63, and the grinding effect of the milling disk 63 on the polarizer body 6610 is improved.

[0033] When in use, the polarizer body 6610 is placed on the top of the carrier 663, and the electric telescopic rod 4 is started, the electric telescopic rod 4 drives the square plate 5 to move, and the motor 61 is started at the same time, the motor 61 drives the rotating shaft 62 to rotate, the rotating shaft 62 drives the milling disk 63 to rotate, the square plate 5 drives the motor 61 to move, the motor 61 drives the rotating shaft 62 to move, the rotating shaft 62 drives the milling disk 63 to move, and the milling disk 63 can contact the top of the polarizer body 6610 during the movement, so as to grind the polarizer body 6610. When the square plate 5 moves toward the electric telescopic rod 4, the square plate 5 drives the rotating plate 651 to move, and is limited by the vertical rod 652, and the rotating plate 651 drives the lifting plate 653 to move vertically along the outer wall of the vertical rod 652. The lifting plate 653 moves straight up, and the bending bar 655 is driven to move up. During the upward movement of the bending bar 655, it will contact with the bottom protrusion of the collar 656, so that the collar 656 moves up along the outer wall of the circular shell 64. The collar 656 drives the bending rod 657 to move up, and the bending rod 657 drives the bearing shell 658 to move up. The bearing shell 658 drives the sliding plate 661 to move up, and the sliding plate 661 drives the bearing frame 663 to move up. The bearing frame 663 drives the polarizer body 6610 to move up, so that the polarizer body 6610 is further moved upward, which improves the fitting effect between the polarizer body 6610 and the milling disk 63, prevents the milling disk 63 from failing to contact the top of the polarizer body 6610 during the reciprocating grinding process, and improves the grinding effect of the milling disk 63 from the side.

[0034] When the carrier 663 drives the polarizer body 6610 to move upward, the reaction force of the milling disk 63 causes the polarizer body 6610 to move downward, and the polarizer body 6610 drives the carrier 663 to move downward. The carrier 663 drives the sliding plate 661 to enter the interior of the carrier shell 658 to prevent the carrier shell 658 from moving upward excessively, causing the milling disk 63 to grind the polarizer body 6610 excessively, thereby improving the grinding effect of the milling disk 63. When the carrier 663 moves toward the interior of the carrier shell 658, the rotating bar 665 is affected by the downward force of the carrier 663. The pressure causes the rotating bar 665 to rotate, and is affected by the limiting groove 666 opened at the bottom of the supporting frame 663. The rotating bar 665 drives the first sliding block 667 to slide along the inner wall of the limiting groove 666, and the first sliding block 667 drives the cross bar 668 to move, and the cross bar 668 drives the flexible card plate 669 to move. The two flexible card plates 669 approach each other, thereby clamping the two sides of the polarizer body 6610 to prevent the position of the polarizer body 6610 from shifting when being ground, thereby improving the stability of grinding and the grinding effect of the milling disk 63.

[0035] When the collar 656 moves up, the collar 656 drives the rotating rod 671 to move. Affected by the setting of the slide groove 672, the rotating rod 671 drives the second slider 673 to slide along the inner wall of the slide groove 672. The second slider 673 drives the connecting frame 674 to move. The connecting frame 674 drives the clamping plate 675 to move. The two clamping plates 675 approach each other. During the movement of the clamping plate 675, the side wall of the flexible card board 669 is contacted to push the side wall of the flexible card board 669 to prevent the top of the flexible card board 669 from tilting when the flexible card board 669 clamps the polarizer body 6610, thereby further improving the clamping effect of the flexible card board 669 on the polarizer body 6610 and improving the grinding effect of the milling disk 63 on the polarizer body 6610. When the electric telescopic rod 4 moves in the opposite direction, the lifting and lowering The plate 653 moves downward, and the lifting plate 653 no longer squeezes the ring 656. At this time, due to the gravity of the polarizer body 6610 and the elastic deformation of the second spring 659, the supporting shell 658 descends vertically along the inner wall of the circular shell 64. During the downward movement of the supporting shell 658, the airflow inside the circular shell 64 enters the interior of the curved pipe 681, and the airflow enters the interior of the annular shell 682 through the curved pipe 681, and the airflow is discharged to the outside through the annular shell 682. At this time, the polarizer body 6610 is sprayed by the airflow during its falling process, so that the powder generated by the grinding of the top of the polarizer body 6610 is sprayed off, so as to prevent the powder from adhering to the top of the polarizer body 6610 and affecting the subsequent repeated grinding of the polarizer body 6610 by the milling disk 63, thereby improving the grinding effect of the milling disk 63 on the polarizer body 6610.
