An automated production method for small prefabricated components according to any one of claims 1 to 9, characterized in that: The steps include: Step 1, batching, controlling the fabric delivery bin (11) and the base material batching bin (12) to deliver the fabric and base material to the vertical shaft mixer and the double shaft mixer respectively, controlling the cement bin to deliver cement to the double shaft mixer to form aggregate and fabric, controlling the plate delivery machine (4) to deliver the plate to the block forming machine (2), and the double shaft mixer and the vertical shaft mixer to deliver the fabric and aggregate to the fabric machine and the aggregate delivery device respectively through the belt conveyor (13); Step 2, batching and loading, controlling the aggregate lifting cylinder (226) to extend, lifting the aggregate hopper (221) so that the aggregates arranged on the belt conveyor (13) enter the aggregate hopper (221), controlling the material lifting cylinder (233) to lift the material hopper (231) so that the material on another belt conveyor (13) enters the material hopper (231), then controlling the aggregate lifting cylinder (226) and the material lifting cylinder (233) to respectively drive the aggregate hopper (221) and the material hopper (231) to descend, controlling the aggregate door opening cylinder (228) and the material door opening cylinder (234) to open the aggregate hopper door and the material hopper door, respectively, so that the aggregates and the material enter the aggregate vehicle (225) and the material vehicle (235), and then lifting the aggregate hopper (221) and the material hopper (231); Step 3, pressing the wet product, controlling the demoulding cylinder (217) to extend, the demoulding cylinder (217) drives the mold frame to move downward, so that the mold frame is located at the top center of the support plate, respectively controlling the aggregate feeding cylinder (227) and the fabric feeding cylinder (236) to extend, respectively pushing the movable ends of the aggregate cart (225) and the fabric cart (232) to tilt, pouring the aggregate and fabric in the aggregate cart (225) and the fabric cart (232) into the mold frame, first pouring in part of the fabric, then dumping the aggregate, and finally pouring in the remaining fabric, then controlling the pressing head cylinder (212) to extend, the pressing head cylinder (212) drives the upper pressing head (216) to move downward, and the upper pressing head (216) cooperates with the mold frame to press the aggregate and fabric to form a wet product; Step 4: demoulding, controlling the vibration motor on the upper pressing head (216) to vibrate to demould the wet product, then controlling the pressing head oil cylinder (212) to drive the upper pressing head (216) to rise, and then controlling the demoulding oil cylinder (217) to drive the mold frame to rise and separate from the wet product; Step 5, transfer and curing, the pallet with the wet product is transported to the plate lifter through the conveyor belt in the block forming machine (2), the plate lifter lifts the pallet, controls the sub-carriage (33) in the programmable mother-and-child car (3) to move to the sub-carriage track in the plate lifter, and then controls the plate lifter to lower the lifted pallet onto the sub-carriage (33), the sub-carriage (33) transports the pallet and the wet product to the programmable mother-and-child car (3), then the programmable mother-and-child car (3) moves to the curing kiln (5), the sub-carriage (33) moves to the sub-carriage track in the curing kiln (5), places the pallet and the wet product in the curing kiln (5), then controls the sub-carriage (33) to take out the dry product that has been cured in the curing kiln (5), and controls the sub-carriage (33) to move to the programmable mother-and-child car (3) at the discharge end of the curing kiln (5); Step 6: Product output. The program-controlled mother-and-child carriage (3) receiving the dry product moves to the pallet lowering machine (9). The child carriage (33) moves to the child carriage track in the pallet lowering machine (9). The pallet on the child carriage (33) is grabbed in the pallet lowering machine (9). After grabbing, the child carriage (33) moves to the program-controlled mother-and-child carriage (3). The pallet lowering machine (9) places the pallet and the dry product on the conveyor belt and transports them to the fully automatic stacking system (8). The fully automatic stacking system (8) separates the pallet and the dry product through the pallet pusher. The dry product is pushed to the finished product conveying system for delivery. The pallet enters the pallet cleaning device for surface cleaning. The pallet is then transported to the pallet turning machine (6) for 180° flipping. After flipping, it is transported to the pallet feeding machine (4) to continue loading the pallet.
