s32 flat turning: then, the upper clamp is pushed to the flat rotating unit through the first left-right translation mechanism, the upper clamp pushed to the flat rotating unit is firstly cleaned by one horizontal rotation and then powdered again, and then is reset by two horizontal rotations, and meanwhile, the lower clamp with the powdered clamp needle is sent to a preheating device of the flat rotating unit by the lower conveying mechanism to be heated;
s33 vertical rotation: the upper clamp with the clamp needle stuck with the powder is pushed to the vertical rotation unit through the first left-right translation mechanism, and is converted into the lower clamp with the clamp needle stuck with the powder after vertical rotation;
s34 turning: sending the lower fixture with the crystal beads subjected to A-side grinding and polishing processing into a turnover unit, pushing the lower fixture bonded with the crystal beads to the turnover unit through a lower conveying mechanism, turning the lower fixture to form an upper fixture, pushing the upper fixture to the next procedure through a second left-right translation mechanism to carry out B-side grinding and polishing operation, and turning the turnover unit with the fixture removed again to enable the lower fixture of the turnover unit to be a vacant position;
the conveying process of the step S3 is as follows: after the butt joint unit finishes working, a first left-right translation mechanism synchronously acts to transfer an upper clamp with crystal beads subjected to A-surface grinding and polishing processing to the butt joint unit, transfer the upper clamp without the beads to a translation unit, transfer the upper clamp with the clamp needles cleaned by brushing needles and subjected to powdering again to a vertical rotation unit, simultaneously with the action of the first left-right translation mechanism, a lower conveying mechanism synchronously acts to convey the lower clamp with the powder applied to the clamp needles after vertical rotation into the translation unit, convey the lower clamp with the powder applied to the clamp needles and heated by rubber powder into the butt joint unit, and convey the lower clamp with the crystal beads bonded after butt joint to an overturning unit, and the action of carrying out B-surface grinding and polishing on the upper clamp bonded with the crystal beads after overturning to the next process by a second left-right translation mechanism is finished within the processing step time of the step S3;
and (S4) grinding and polishing surface B: pushing the upper fixture turned after the butting to each process of B-surface grinding and polishing, and grinding and polishing the crystal beads at each angle according to the processing requirements of products;
s5, blanking: the upper clamp which is ground and polished with crystal beads is sent into a blanking device, the crystal beads on the clamp needles are separated through heating of the high-frequency tube, and then the crystal beads are guaranteed to fall into a blanking channel through needle brushing, so that the processing action is completed.
2. A method of controlling an automatic production inspection system of a polishing machine as claimed in claim 1, wherein: in the step S3, before the upper fixture for finishing the grinding and polishing of the surface A of the first crystal bead reaches the butt joint unit, the hollow fixture is subjected to powdering in the flat-turn unit in advance, and is vertically turned and then conveyed to the flat-turn unit to finish the preheating action, so that the upper fixture for finishing the grinding and polishing of the surface A of the crystal bead and the lower fixture for heating the rubber powder can be synchronously conveyed to the butt joint unit, and the butt joint operation can be quickly started.
3. A method of controlling an automatic production inspection system of a polishing and grinding machine according to any one of claims 1 to 2, wherein: the step of S2 includes 90 ° grinding, 54 ° primary grinding, 18 ° secondary grinding, 54 ° secondary grinding, 18 ° polishing, 54 ° polishing, and 90 ° polishing processes performed in this order; the step of S4 comprises the working procedures of 90-degree grinding, 54-degree primary grinding, 18-degree primary grinding, 54-degree secondary grinding, 18-degree polishing, 54-degree polishing and 90-degree polishing which are sequentially carried out; a vacancy cooling step is arranged after the step S1 and before the step S5; each step is provided with a visual detection device, the product processing process of the crystal beads is detected in real time, and the fault warning function is realized.
