Prefabricated part mechanical demolding detection device and demolding detection method thereof

The invention relates to a prefabricated part mechanical demolding detection device and a demolding detection method thereof.The demolding detection device comprises a demolding piece (2) and an upper mold (72) and is characterized in that the demolding piece (2) is formed by combining a first lower mold (20) and a second lower mold (21), and a prefabricated part is placed in an arc-shaped groove (24) formed by the first lower mold (20) and the second lower mold (21); the first lower die (20) and the second lower die (21) can rotate to form a discharging channel so that a prefabricated part can be placed on the base (1). The arc-shaped grooves (24) of the first lower mold (20) and the second lower mold (21) are provided with pneumatic mechanisms and/or cooling mechanisms for assisting demolding; before the prefabricated part is demoulded, the upper camera (61) and the lower camera (62) respectively collect image data of the front surface and the back surface of the prefabricated part, and the control unit com
