[0033] Working principle: When rounding the corners, place the display panel on the support plate 3, and place the edge of the panel against the limit plate 4. At this time, start the motor 12, and the motor 12 will drive the drive shaft 14 to rotate through the coupling 13. The rotation of the drive shaft 14 will cause the wind wheel 29 to rotate. When the wind wheel 29 rotates, wind will be generated inside the wind cover 30. After the wind is generated, it will be transported through the connecting pipe 43 and the connecting pipe 31. Since the end of the connecting pipe 31 is connected to the sealing pipe 32, and the sealing block 38 and the spring 40 are arranged inside the sealing pipe 32, the wind will encounter resistance after entering the sealing pipe 32 and cannot pass. Therefore, the wind will enter the sleeve 42 through the connecting pipe 43, so that the air inside the sleeve 42 The pressure increases, and the sliding block 44 is moved by the action of the air pressure, and the movement of the sliding block 44 causes the sliding rod 45 to drive the extrusion plate 47 to move, so that the extrusion roller 49 moves to fit the panel, and the extrusion roller 49 pressurizes and fixes the panel by the action of the air pressure. After that, since the extrusion roller 49 cannot continue to move, the wind force cannot continue to be delivered to the inside of the sleeve 42. At this time, the wind force is concentrated into the sealing tube 32. The wind force at this time is enough to blow the sealing block 38, so the wind force will enter the inside of the connecting hose 34 through the sealing tube 32, and then enter the inside of the sleeve 26 through the connecting hose 34, so that the pressure inside the sleeve 26 increases, so the movable block 25 drives the push rod 24 to move by the action of the air pressure. , the movement of the push rod 24 drives the moving block 23 to move, and then the sliding plate 7 drives the fixed plate 8 and the angle grinder 9 to move, so that the angle grinder 9 fits the corner of the panel. In this process, the rotation of the driving shaft 14 causes the incomplete gear 18 to rotate. When the incomplete gear 18 rotates, it will mesh with the first rack 19 and the second rack 21 respectively. When the incomplete gear 18 meshes with the first rack 19, it will drive the first rack 19 to move. Therefore, the movement of the first rack 19 causes the connecting plate 20 to drive the second rack 21 to move. Therefore, the movement of the second rack 21 causes the third rack 22 to move. The movement of the third rack 22 causes the first flat gear 16 to rotate, thereby causing the rotation The shaft 5 drives the rotating rod 6 to rotate, so the sliding plate 7 and the fixed plate 8 drive the angle grinder 9 to rotate, and then the incomplete gear 18 will mesh with the second rack 21. After the incomplete gear 18 meshes with the second rack 21, the incomplete gear 18 will drive the second rack 21 to move in the opposite direction. At this time, the third rack 22 causes the first flat gear 16 to rotate in the opposite direction due to the reverse movement of the second rack 21, thereby driving the rotating shaft 5 to rotate in the opposite direction, thereby rotating the rotating rod 6 in the opposite direction. Therefore, under the rotation action of the incomplete gear 18, the rotating shaft 5 will rotate back and forth left and right, thereby causing the angle grinder 9 to swing left and right, and cooperate with the movement of the moving block 23 to keep the angle grinder 9 in a state of being in contact with the panel, thereby automatically grinding the panel.

[0034] It is worth noting that: after the operation is completed, the motor 12 will reverse, and suction will be generated inside the wind hood 30, so that the airflow inside the sleeve 26 and the sleeve 42 will be sucked away, so that the air pressure inside the sleeve 26 and the sleeve 42 will be reduced. At this time, the sliding block 44 and the movable block 25 will move in the opposite direction and reset due to the action of negative pressure. A first tension spring 27 is arranged inside the sleeve 26, and a second tension spring 56 is arranged inside the sleeve 42. Through the arrangement of the first tension spring 27 and the second tension spring 56, the sliding block 44 and the movable block 25 can be quickly reset to improve work efficiency.

[0035] It is particularly noted that when grinding the angle of the panel, after placing the panel against the limit plate 4, starting the switch can operate another machine to grind the angle of the panel. After the grinding is completed, you only need to change the angle of the panel. That is, during the process of grinding the angle of the panel, no manual intervention is required. During this period of time, the workers can operate another one or more machines, thereby improving efficiency and reducing labor input.

[0036] It is also worth noting that: when the squeezing roller 49 squeezes the panel, by starting the motor 51, the motor 51 will drive the second flat gear 52 to rotate, and the rotation of the second flat gear 52 will drive the third flat gear 53 to rotate, thereby driving the gear belt 54 to rotate, and the gear belt 54 will drive the fourth flat gear 55 to rotate. Therefore, when the motor is started, multiple groups of connecting shafts 48 all rotate at the same time, and the rotation of the connecting shaft 48 drives the squeezing roller 49 to rotate. The rotation of the squeezing roller 49 makes the panel fit tightly with the limit plate 4, thereby avoiding the situation where the angle grinder 9 squeezes the panel and causes the panel to shift.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
