[0023] The lifting assembly includes a plurality of vertically arranged lifting cylinders 6, the tops of the plurality of lifting cylinders 6 are fixed at the bottom edge of the lower fixture plate 2, and a plurality of first through holes 7 are vertically opened at the bottom edge of the lower fixture plate 2, and the plurality of first through holes 7 correspond to the plurality of lifting cylinders 6 one by one up and down, respectively. The tops of the output shafts of the lifting cylinders 6 vertically penetrate the corresponding first through holes 7, and the plurality of first through holes 7 correspond to the plurality of semi-sunk holes 5 one by one up and down, respectively. Positioning pins 8 are fixed to the tops of the lifting cylinders 6, and the plurality of positioning pins 8 correspond to the plurality of semi-sunk holes 5 one by one, respectively. The positioning pins 8 are inserted into the corresponding semi-sunk holes 5. Specifically, when the lifting cylinders 6 are running, the middle plate 4 can be driven to rise and fall, and the use of the upper fixture plate 1 that is turned over and pressed down can be used to squeeze and fit the flexible circuit board covering film with the upper pressing plate 3, and the middle plate 4 is not penetrated by the designed semi-sunk hole 5 structure, so that the defect of carbon oxygen aluminum foreign matter being brought into the fixture surface through the through hole as the lifting cylinders 6 are running is effectively avoided;

[0024] The covering film positioning assembly includes four second through holes 9, and the four second through holes 9 are vertically opened at the four corners of the lower fixture plate 2, and the four corners of the top of the middle plate 4 are provided with mounting grooves 10, and the bottom of the mounting grooves 10 are vertically provided with third through holes 11, and the four third through holes 11 correspond to the four second through holes 9 one by one up and down, and the bottom ends of the third through holes 11 are connected to the top ends of the corresponding second through holes 9, and vacuum suction cups 12 are fixed in the mounting grooves 10, and the bottom ends of the four vacuum suction cups 12 are fixedly connected with suction hoses 13.
