[0026] The sheet Mylar automatic assembly equipment of the present application has a sheet feeder that can automatically transfer the sheet Mylar stacked in the material rack to the loading rack in sequence, and then automatically transfer the sheet Mylar on the loading rack to the fixture plate through the transfer robot arm. The Mylar sheet assembly process has a high degree of automation and high production efficiency. Four loading suction cups are symmetrically installed on the lower side of the suction cup suspension of the loading robot arm, which can evenly and reliably absorb the sheet Mylar to ensure that the sheet Mylar does not fall during the loading and transfer process, and the reliability is high. The loading robot arm adopts a linear motor and a lifting motor to realize the horizontal movement and the up and down movement of the loading suction cup. The movement is stable during the material transfer process and the reliability is good.
