The long-stroke cylinder 62 and the blocking cylinder 67 are fixed on the limiting module fixing frame 66 through the cylinder fixing plate 65, the three blocking guide rods 63 are fixed on the blocking cylinder 67 through the blocking cylinder flange 64, and when the front-end magnetic contact sensor 69 senses that a workpiece passes through, the blocking cylinder 67 is triggered to ascend, so that the blocking guide rods 63 block the workpiece to stop moving. The carrier 60 is fixed on a long-stroke cylinder 62 through a carrier support 61, so that the carrier can vertically move up and down through the conveyor belt, and when the workpiece is blocked by a blocking guide rod 63, the workpiece can simultaneously sense a rear-end magnetic contact sensor 68, so that the long-stroke cylinder 62 is triggered to ascend. When the external air pressure sensor of the turnover module 36 senses that the negative pressure value of the vacuum chuck 01 reaches the standard, the long-stroke air cylinder 62 descends and returns to the original position.
After the equipment is started, the conveyer belt motor 34 drives the conveyer belt 39 to continuously run, workpieces enter the equipment from the inlet sand avoiding area 33, when the front-end magnetic contact sensor 69 is sensed, the blocking cylinder 67 rises, the blocking guide rod 63 is used for blocking and stopping the workpieces and simultaneously sensing the rear-end magnetic contact sensor 68, the long guide rod cylinder 62 is triggered to support the carrying platform 60 to rise, the workpieces are made to contact with the vacuum chuck 01 on the overturning module 36, and the vacuum chuck 01 turns from positive pressure to negative pressure to tightly suck the workpieces.

After painting or sandblasting, the index plate 05 rotates 90 degrees in 2 seconds, the next workpiece is switched to continue processing, when the workpiece which is painted or sandblasted rotates to the lowest end, the vacuum suction cup 01 turns to positive pressure from negative pressure, the air cylinder 67 is stopped from descending and returning, the stopping guide rod 63 is lower than the plane of the conveying belt, the abrasive inside the workpiece can be poured when the workpiece which is sandblasted is placed on the conveying belt, when the workpiece flows to the outlet of the equipment and reaches the outlet sand avoiding area 38, the abrasive dust on the surface of the conveying belt and the surface of the workpiece is blown to the sand storage hopper 40 by the high-speed air curtain of the air knife 46, and the workpiece which is painted does not need to be cleaned by the air knife 46. The negative pressure buffer zone of spun dust when the spray gun module trades with sand blasting gun through dust absorption mouth baffle 48 below, and in the large granule dust fell back to storing up sand hopper, the small granule dust was inhaled dust separator 35 through negative pressure dust absorption mouth 47 and tuber pipe 30 in, through secondary buffering screening, will relatively more large granule dust separates once more and come back to receive and store up sand hopper 40 in, through dust separator 35 top export discharge dust waste gas at last.

When the workpiece after sand blasting is conveyed to the outlet sand avoiding area 38 along with the belt line 39, the air knife 46 at the outlet inclines by 45 degrees to blow air into the equipment so as to clean the dust carried on the conveying belt and the workpiece, thereby the dust is left in the equipment to reduce the loss of the carborundum raw material, and the workpiece after paint spraying does not need to use the air knife 46. The inlet and the outlet at the two ends of the equipment can be externally connected with two assembly lines, so that unmanned operation is realized.
