[0038] Principle: When the floor drain is processed by CNC machine, the loading and unloading manipulator 2 on the truss 1 is used to grab the floor drain in the loading rack 4, and then the loading and unloading manipulator 2 can grab the floor drain into the CNC machine tools on both sides for processing. After the floor drain is processed, the loading and unloading manipulator 2 is used to set the floor drain on the unloading column 5; wherein, when a group of loading racks 4 and unloading columns 5 complete loading and unloading, the first servo motor 33 drives the driving gear 331 to rotate, and the driving gear 331 can drive the rotating seat 32 to rotate through the gear ring 321, and the rotating seat 32 can drive the turntable 31 to rotate, so as to move the next group of loading racks 4 and unloading columns 5 to the grabbing position of the loading and unloading manipulator 2, and finally the floor drain can be stably loaded and unloaded conveniently on the lower side of the loading and unloading manipulator 2; When the loading and unloading robot 2 grabs the floor drains in the loading rack 4 one by one, the second servo motor 781 is first used to drive the cam 782 to rotate, and the cam 782 can drive the driving arm 783 to swing downward, thereby driving the connecting swing arm 73 to swing upward, and the connecting spring 784 is stretched, and when the cam 782 rotates toward the side away from the driving arm 783, the connecting spring 784 can elastically recover, and the driving arm 783 can be driven to swing upward through the connecting spring 784, thereby driving the connecting swing arm 73 to swing downward, and finally the connecting swing arm 73 can be driven to swing up and down; at the same time, when the connecting swing arm 73 swings downward, the connecting swing arm 73 drives the driving swing arm 74 to move downward, and the lower end of the driving swing arm 74 is always in contact with the step platform 72 under the action of its own weight until the driving swing arm 74 crosses a step platform 72; then the connecting swing arm 73 can swing upward, and at this time the connecting swing arm The cam 72 is pressed against the bottom surface of the step 72, and the locking cam 73 is pressed against the bottom surface of the step 72, so that the locking cam 73 is pressed against the bottom surface of the step 72. At the same time, when the loading and unloading robot 2 sets the floor drain on the unloading column 5, the driving cylinder 323 is used to drive the second push plate 52 to move downward step by step, so as to facilitate the stable stacking of multiple floor drains on the unloading column 5, and each floor drain set on the unloading column 5 will first be aligned with the position of the airway 51 at the upper end of the unloading column 5; wherein when the second servo motor 781 drives the cam 782 to rotate downward, the cam 782 can also drive the piston column 83 and the piston block 82 to move downward in the piston cylinder 81 through the cross bar 84, and the return spring 85 is compressed, so that the air in the piston cylinder 81 is pressed into the air supply hose 86, and the gas in the air supply hose 86 can enter the airway 51, and then the gas ejected from the airway 51 can The inner wall of the floor drain is sprayed and cleaned, and at the same time, the second servo motor 781 will also drive the active bevel gear 7811 to rotate. At this time, the active bevel gear 7811 can drive the discharge column 5 to rotate through the driven bevel gear 53. After the discharge column 5 rotates, it can drive the airway 51 to rotate around the central axis of the discharge column 5, and then the inner wall around the floor drain is comprehensively sprayed. There is no need for the operator to perform additional spraying and cleaning on each floor drain subsequently, and finally the inner wall of the floor drain can be cleaned on the discharge column 5; and when the second servo motor 781 drives the cam 782 to rotate upward, the reset spring 85 can recover elastically, thereby attracting external gas through the airway 51 and the air supply hose 86 for the next jet.
