[0035] The working principle and use process of the present invention are as follows: when in use, the second retractable driving member 389 is controlled to extend so that the second supporting metal plate 393 moves upward, and then the user places the LCD panel to be ground (hereinafter referred to as the workpiece) on the material fixing member 392, and then the material fixing member 392 is controlled to adsorb and fix the workpiece, and then the second retractable driving member 389 is controlled to contract so that the second supporting metal plate 393 returns to the initial position, and then the first retractable driving member 30 is controlled to extend, and the movable pressure regulating plug 388 is moved downward by the extension of the first retractable driving member 30, and part of the dustproof liquid 33 at the bottom of the convex storage box 34 is instantly pressed into the adjustable material storage tube 31 by the downward movement of the movable pressure regulating plug 388, so that the dustproof liquid 33 instantly submerges the workpiece to achieve wetting of the workpiece, and at the same time, the second supporting metal plate 393 is driven to vibrate by the vibration motor 394, and the workpiece vibrates at this time, and the vibration of the workpiece causes the workpiece to collide with the dustproof liquid 33 to achieve flushing of the workpiece surface;

[0036] Then, the first retractable driving member 30 is controlled to retract so that the movable pressure regulating plug 388 is reset, and then the third retractable driving member 64 is controlled to extend so that the grinding disc 60 moves downward, and the grinding disc 60 contacts the workpiece by moving downward, and then the grinding disc 60 is driven to rotate by the power output member 65 to grind the workpiece. During the grinding process, the workpiece is continuously moistened by the flushing nozzle 383 to avoid a large amount of dust being dispersed during the grinding process. At the same time, the power supply of the exhaust fan 35 is turned on, and the air at the top of the adjustable material storage pipe 31 is extracted through the operation of the exhaust fan 35, so as to generate negative pressure at the top of the adjustable material storage pipe 31 to achieve further dust removal, and the shielding effect of the ring-shaped metal cover 384 on the dust can effectively avoid the phenomenon of dust dispersion;

[0037] After grinding is completed, the power output member 65 is controlled to return to the initial position, and then the first retractable driving member 30 is controlled to extend. The movable pressure regulating plug 388 is moved downward by the extension of the first retractable driving member 30. The movable pressure regulating plug 388 is moved downward to instantly press part of the dustproof liquid 33 at the bottom of the convex storage box 34 into the adjustable material storage tube 31, so that the dustproof liquid 33 instantly submerges the workpiece to achieve flushing of the workpiece. At the same time, the second supporting metal plate 393 is driven to vibrate by the vibration motor 394. At this time, the workpiece vibrates to achieve further flushing of the workpiece. After flushing is completed, the control The first retractable driving member 30 contracts to reset the movable pressure regulating plug 388, and then the workpiece is further rinsed by spraying water through the flushing nozzle 383, so as to further rinse the workpiece. After the rinsing is completed, the second retractable driving member 389 is controlled to extend so that the upper surface of the workpiece is flush with the bottom of the gas transmission metal pipe 385. At this time, the power of the exhaust fan 35 is turned on, and the exhaust fan 35 forms a negative pressure airflow on the upper surface of the workpiece to achieve rapid drying of the workpiece. Then, the second retractable driving member 389 is controlled to further extend to lift the workpiece, so that the user can take out the processed workpiece;

[0038] Therefore, the LCD panel can be quickly and fully ground through the cooperation of multiple structures, and multiple dust removal is performed during the grinding process, which effectively prevents the device from emitting dust during use and prevents the dust from scattering everywhere and causing harm to the health of the staff. Secondly, the present invention can quickly and fully clean and dry the ground LCD panel, which is convenient for users to perform subsequent processing on the ground LCD panel. In addition, the present invention has a simple structure, is easy to use, and is worthy of promotion and use.
