8. A working method of a curved glass cover plate production device is characterized by comprising the following steps: comprises the following steps

S1: the first mould transfer platform moves to a mould opening station, and after the mould is grabbed from the outlet of the thermoforming machine, the mould is transferred to the first mould transfer platform positioned at the mould opening station under the drive of the mould blanking driving assembly; at this time, the child-mother die of the die is positioned above the bottom die;

s2: after the die blanking driving assembly drives the die blanking clamping assembly to move upwards by a set distance, the first die blanking clamping assembly just clamps the female die of the sub-female die, the sucker vertical moving assembly drives the blanking sucker to move downwards to be in contact with the upper surface of the sub-die, and then the die blanking driving assembly drives the blanking clamping assembly to move upwards by the set distance again, and at the moment, the female die moves upwards by the set distance relative to the bottom die; then the blanking sucker is adsorbed on the upper end surface of the sub-die at least once and then releases the sub-die; then, the first die blanking clamping assembly and the second die blanking clamping assembly simultaneously clamp and adsorb the master die and the sub die respectively, and the clamping and adsorbing die blanking driving assembly drives the die blanking driving assembly to move upwards for a set distance to separate the sub die from the bottom die; opening the die;

S3: the first mould transfer platform drives the bottom mould to move to a glass blanking station, and the glass blanking mechanism takes out and transfers the glass cover plate in the bottom mould to the discharging material rack;

s4: the first mould transfer platform drives the bottom mould to move to a pouring station, and the pouring mechanism clamps and overturns the bottom mould by 180 degrees and then returns the bottom mould to the first mould transfer platform;

s5: the first mould transfer platform drives the bottom mould to return to the mould opening station; the mold blanking clamping assembly moves downwards for a set distance to enable the child-mother mold and the bottom mold to be buckled, and then the first mold blanking clamping assembly and the second mold blanking clamping assembly simultaneously release the mother mold and the child mold; after releasing, the die blanking clamping assembly moves upwards;

s6: the first mould transfer platform transfers the moulds to the inlet end of the mould conveying mechanism, the mould conveying mechanism acts to convey the moulds to the second mould transfer platform, and at the moment, the second mould transfer platform moves to the outlet end of the mould conveying mechanism;

s7: the turnover mechanism clamps and turns over the die on the die conveying mechanism by 180 degrees and then returns the die to the die conveying mechanism, and the die conveying mechanism continuously drives the die to move to the outlet end of the die conveying mechanism; at this time, the bottom die of the die is positioned above the sub-master die;

S8: the second mould transferring platform transfers the mould at the outlet end of the mould conveying mechanism to a mould closing station; the mold feeding clamping assembly is driven by the mold feeding clamping driving assembly to move downwards for a set distance, a feeding sucker of the second mold clamping assembly is adsorbed on the bottom surface of the bottom mold, and then the mold feeding clamping assembly moves upwards to separate the bottom mold from the sub-female mold, so that a cavity of the sub-female mold is exposed upwards;

s9: the second mould transfer platform transfers the sub-mother mould to a glass loading station; the glass feeding mechanism is used for pre-placing the glass cover plate to be processed on the glass positioning mechanism for positioning, and the positioned glass cover plate is taken out by the glass feeding mechanism and placed into the child-mother die;

s10: the second mould transfer platform transfers the sub-master mould to a mould closing station; the mold feeding clamping assembly is driven by the mold feeding clamping driving assembly to move downwards so as to enable the bottom mold to be buckled on the sub-female mold, and then the feeding sucker of the second mold clamping assembly releases the bottom mold, so that the bottom mold and the sub-female mold are clamped; after the die is closed, the feeding clamping component of the die moves upwards;

s11: the second mould transfer platform transfers the child and mother moulds to the outlet end of the mould conveying mechanism, the mould conveying mechanism reversely conveys the moulds to the turnover mechanism, the turnover mechanism reversely overturns the moulds for 180 degrees again and then positively conveys the moulds to the outlet end by the mould conveying mechanism, and the second mould transfer platform transfers the moulds to the mould closing station by the outlet end of the mould conveying mechanism again;

S12: the die feeding clamping assembly is driven by the die feeding clamping driving assembly to move downwards for a set distance which is not more than the set distance in the step S8, so that the first die feeding clamping assembly of the die feeding clamping assembly just clamps the bottom die of the die, but the sucker of the second die feeding clamping assembly is not contacted with the upper end face of the sub-master die of the die; the mold feeding clamping assembly is driven by the mold feeding clamping driving assembly to move upwards and move to the position above the inlet of the thermoforming machine;

s13: the mold loading clamping assembly moves downwards, the mold is moved into an inlet of the thermoforming machine to release the mold, and the mold enters the thermoforming machine;

s14: and sequentially cycling according to the steps.
