[0014] Furthermore, the method for a static pressure air floating direct drive turntable comprises the following steps:

[0015] S1: Start the air pump before use. The air pump will draw air into the circular bellows through the connecting pipe. At this time, the transmission blades will rotate under the action of the air, and the transmission blades will drive the circular rod to rotate, and the circular rod will drive the connecting plate to rotate, and the connecting plate will drive the lever to rotate. During the rotation of the lever, the lever will contact the inclined plate. Under the action of the inclined surface of the inclined plate and the push of the lever, the inclined plate will move toward the direction close to the base, and the inclined plate will drive the transmission rod to move, and the transmission rod will drive the circular plate to move. At this time, the vibration spring will be compressed and deformed. After the lever leaves the inclined plate, under the elastic force of the vibration spring, the vibration spring will push the circular plate to move toward the connecting plate. At this time, the circular plate will hit the front inner wall of the circular groove, and the vibration generated will shake off the fine dust impurities in the filter hole, and the shaken dust will be discharged out of the circular groove along the inclined groove in the circular groove;

[0016] S2: During the rotation of the circular rod, the limit circular plate will be driven to rotate, the limit circular plate will be driven to rotate the fixed plate, the fixed plate will be driven to rotate the strip box, the strip box will be driven to rotate the cleaning spring, the cleaning spring will be driven to rotate the trapezoidal block, the centrifugal force generated by the rotation will throw the trapezoidal block out, and the trapezoidal block will move away from the circular rod. During the rotation of the trapezoidal block, the dust on the surface of the circular plate will be scraped off to prevent stubborn impurities from being adsorbed on the circular plate and affecting the gas transmission of the device. When the circular plate hits the front inner wall of the circular groove, it will first contact the inclined surface of the trapezoidal block. At this time, the trapezoidal block will slide into the strip box under the action of the inclined surface, which will not affect the distance of the circular plate hitting the circular groove. After the circular plate hits the circular groove, the dust will be directly shaken out of the circular groove;

[0017] S3: The air sucked into the air pump will be discharged from the air pipe into the annular air box, and then the air will enter the circular air groove from several air inlet holes. As the air is continuously input into the circular air groove, the air pressure will continue to increase, and the air pressure will push the shaft upward. At this time, the shaft will drive the turntable to rise, and the corresponding rectangular rod will be stuck in a fixed position and remain motionless. The gas in the circular air groove will be discharged from the ventilation circular hole into the circular installation groove. At this time, the device will be propped up by the air, thus completing the support effect of the device;

[0018] S4: After the air passes through the circular mounting groove, it will move along the gap between the circular mounting groove and the turntable and enter the sealing box. The air will push the annular limit plate down. At this time, several sealing springs will be stretched and deformed. When the annular limit plate passes through several air outlets, the gas in the device will be discharged from several air outlets. When the device is not used, the sealing spring will recover and drive the annular limit plate to rise and pass through the air outlet again. At this time, a closed space will be formed in the sealing box.

[0019] The present invention has the following beneficial effects:

During the rotation of the lever, the lever will contact the inclined plate. Under the action of the inclined surface of the inclined plate and the push of the lever, the inclined plate will move toward the direction close to the base, and the inclined plate will drive the transmission rod to move, and the transmission rod will drive the circular plate to move. At this time, the vibration spring will be compressed and deformed. After the lever leaves the inclined plate, under the elastic force of the vibration spring, the vibration spring will push the circular plate to move toward the connecting plate. At this time, the circular plate will hit the front inner wall of the circular groove, and the vibration generated will shake off the fine dust impurities in the filter hole. The shaken dust will be discharged out of the circular groove along the inclined groove in the circular groove, effectively preventing the dust impurities from clogging the filter hole, so that the air pressure of the device cannot keep up and affect the operation of the device, thereby affecting the normal operation of the device;

During the rotation of the trapezoidal block, dust on the surface of the circular plate will be scraped off to avoid stubborn impurities adsorbed on the circular plate and affecting the gas supply of the device. When the circular plate hits the front inner wall of the circular groove, it will first contact the inclined surface of the trapezoidal block. At this time, the trapezoidal block will slide into the strip box under the action of the inclined surface, which will not affect the distance of the circular plate hitting the circular groove. After the circular plate hits the circular groove, the dust will be directly vibrated out of the circular groove, thereby improving the cleaning effect and reducing the residual dust in the circular groove.

[0022] (3) The present invention provides a static pressure air-floating direct-drive turntable. The air sucked into the air pump will be discharged from the air delivery pipe into the annular air delivery box, and then the air will enter the circular air groove from a plurality of air inlet holes. As the air is continuously input into the circular air groove, the air pressure will continue to increase, and the air pressure will push the rotating shaft upward. At this time, the rotating shaft will drive the turntable to rise, and the corresponding rectangular rod will be stuck in a fixed position and remain motionless. The gas in the circular air groove will be discharged from the ventilation circular hole into the circular mounting groove. At this time, the device will be propped up by the air, thus completing the support effect of the device;

[0023] (4) The present invention is a static pressure air floating direct-drive turntable. After the air passes through the circular mounting groove, it will move along the gap between the circular mounting groove and the turntable and enter into the sealing box. The air will push the annular limit plate down. At this time, a number of sealing springs will be stretched and deformed. After the annular limit plate passes through a number of air outlets, the gas in the device will be discharged from the several air outlets.

4. A method for using a static pressure air floating direct drive turntable, using the static pressure air floating direct drive turntable as claimed in claim 3, characterized in that: The steps are as follows: S1: Before use, the air pump (704) is started. The air pump (704) draws air into the circular bellows (701) through the connecting pipe (703). At this time, the transmission blade (702) rotates under the action of the air drawing. The transmission blade (702) drives the circular rod (507) to rotate. The circular rod (507) drives the connecting plate (508) to rotate. The connecting plate (508) drives the lever (509) to rotate. During the rotation of the lever (509), the lever (509) contacts the inclined plate (506). Under the action of the inclined surface of the inclined plate (506) and the push of the lever (509), the inclined plate (506) moves in a direction close to the base (1). The inclined plate ( The transmission rod (506) drives the transmission rod (505) to move, and the transmission rod (505) drives the circular plate (503) to move. At this time, the vibration spring (502) will be compressed and deformed. After the lever (509) leaves the inclined plate (506), under the elastic force of the vibration spring (502), the vibration spring (502) will push the circular plate (503) to move in a direction close to the connecting plate (508). At this time, the circular plate (503) will hit the front inner wall of the circular groove (501), and the vibration generated will shake off the fine dust impurities in the filter hole (504), and the shaken dust will be discharged from the circular groove (501) along the inclined groove in the circular groove (501); S2: During the rotation of the circular rod (507), the limiting circular plate (602) is driven to rotate, the limiting circular plate (602) is driven to rotate the fixing plate (603), the fixing plate (603) is driven to rotate the bar box (604), the bar box (604) is driven to rotate the cleaning spring (605), the cleaning spring (605) is driven to rotate the trapezoidal block (606), and the centrifugal force generated by the rotation will throw the trapezoidal block (606), at which time the trapezoidal block (606) will move in a direction away from the circular rod (507). During the rotation of the trapezoidal block (606), The dust on the surface of the circular plate (503) is scraped off to prevent stubborn impurities from being adsorbed on the circular plate (503) and affecting the gas transmission of the device. When the circular plate (503) hits the front inner wall of the circular groove (501), it first contacts the inclined surface of the trapezoidal block (606). At this time, the trapezoidal block (606) slides into the bar box (604) under the action of the inclined surface, and does not affect the distance of the circular plate (503) hitting the circular groove (501). After the circular plate (503) hits the circular groove (501), the dust is directly shaken out of the circular groove (501); S3: The air sucked into the air pump (704) will be discharged from the air delivery pipe (804) into the annular air delivery box (801), and then the air will enter the circular air groove (805) from a plurality of air inlet holes (806). As the air is continuously input into the circular air groove (805), the air pressure in the circular air groove (805) will continue to increase, and the air pressure will push the rotating shaft (707) upward. At this time, the rotating shaft (707) will drive the turntable (708) to rise, and the corresponding rectangular rod (807) will be stuck in a fixed position and remain motionless. The gas in the circular air groove (805) will be discharged from the ventilation circular hole (808) into the circular installation groove (706). At this time, the device will be propped up by the air, thus completing the support effect of the device; S4: After the air passes through the circular mounting groove (706), it moves along the gap between the circular mounting groove (706) and the turntable (708) and enters the sealing box (901). The air pushes the annular limiting plate (904) down. At this time, a plurality of sealing springs (902) are stretched and deformed. When the annular limiting plate (904) passes through a plurality of air outlet holes (903), the gas in the device is discharged from the plurality of air outlet holes (903). When the device is not used, the sealing spring (902) will recover and drive the annular limiting plate (904) to rise and pass through the air outlet holes (903) again. At this time, a closed space is formed in the sealing box (901).
