After the paint spraying or the sand blasting is finished, the index plate 62 rotates 90 degrees within 2 seconds, the next workpiece is switched to continue to be processed, when the workpiece subjected to the paint spraying or the sand blasting is rotated to the lowest end, the vacuum chuck 64 rotates from negative pressure to positive pressure, the blocking cylinder 40 descends and returns to the original position, the blocking guide rod 38 is lower than the plane of the conveying belt, the abrasive material in the workpiece can be dumped when the workpiece subjected to the sand blasting is placed on the conveying belt, the pneumatic mechanical clamping jaw piece 59 on the pneumatic mechanical clamp 46 drives the arc clamping arm to open when the workpiece flows to the reversing turnover module 15, the lifting cylinder 48 descends to enable the arc clamping arm to be flush with the waist of the workpiece, the lifting cylinder 48 ascends again when sensing a clamping signal of the pneumatic mechanical clamp 46, meanwhile, the conveying belt 08 moves towards the output direction, and the rotating cylinder 47 rotates for 180 degrees when in the moving process, so that the pneumatic mechanical clamp rotates to realize the front and back of the workpiece. When the workpiece with the front side and the back side switched reaches the upper side of the output conveyer belt 08, the lifting cylinder 48 descends again, the workpiece is placed on the output conveyer belt 08, then the lifting cylinder 48 ascends and returns to the original position, the rotary cylinder 47 also rotates and returns to the original position in the process that the sliding table moves towards the direction of the input conveyer belt, the output conveyer belt 08 continuously runs, the workpiece reaches the output end overturning module, and the matching of the limiting module and the overturning module and the spray painting and sand blasting actions are repeated. When the spray gun module is replaced with the sand blasting gun, the sprayed dust passes through the negative pressure buffer area below the dust collection opening baffle 84, large-particle dust falls back into the sand storage hopper 05, small-particle dust is sucked into the dust separator 02 through the negative pressure dust collection opening 12 and the exhaust pipe 01, and after secondary buffer screening, the relatively large-particle dust is separated again and is recovered into the sand storage hopper 05, and finally dust and waste gas are discharged through the outlet above the dust separator 02. The rear part of the reversing and overturning area 04 of the equipment is provided with a shutter type rear door 14, and the negative pressure environment is arranged in the equipment during operation, so that external air can be sucked into the equipment through the shutter, the dust amount of the reversing and overturning module area 04 is reduced to the greatest extent, and the influence of dust on the reversing and overturning module is reduced.
When the workpiece rotates back to the bottommost part, the blocking air cylinder 40 descends and returns to the original position, the vacuum chuck 64 changes to positive pressure, the workpiece subjected to paint spraying or sand blasting is placed on the output conveying belt 08 and conveyed to the equipment outlet, the vacuum chuck 64 continuously blows air outwards at the positive pressure until the workpiece to be treated in the next round contacts the vacuum chuck 64 again, the negative pressure is converted, and therefore dust covered on the workpiece can be blown away, and dust entering the air pipe before the workpiece is sucked can be prevented. When the workpiece with the processed front and back faces flows to the outlet sand-avoiding area 16, the high-speed air curtain of the air knife 86 blows the surface of the conveying belt and abrasive dust on the surface of the workpiece into the sand storage hopper 05, so that the loss of the silicon carbide abrasive is prevented, and the sprayed workpiece does not need to be cleaned by starting the air knife 86. The device inlet and outlet can be externally connected with two production lines, so that full-automatic unmanned operation is realized.
