The first section of the film released from the roll is laid on each station. The splicing between the tail section of the previous roll and the first section of the next roll is completed according to steps 1-6. Step 1: The film splicing equipment feeds the film material (A01) of the previous roll of film. When it is detected that the roll of film has been supplied to the end, the film material feeding is stopped; the film splicing assembly (3042) moves downward along Z and presses the film material onto the lower station through the film pressing head (B13) and the heat splicing module (B06); Step 2: The cutter (B05) in the film bonding assembly (3042) cuts the film material, and the heat bonding module (B06) vacuum adsorbs the film material below it through the air hole. Then the film bonding assembly (3042) moves upward along Z. Step 3: The working module (304) moves along the Y direction, so that the heat bonding module (B06) moves with the adsorbed film material to the top of the next station; then the film bonding assembly (3042) moves downward along the Z direction, so that the film material adsorbed by the heat bonding module is pressed together with the first section of the film material of the next roll of film at the lower station. Step 4: The heating element in the heat bonding module (B06) releases heat energy, which enables the two layers of film to be thermally bonded; after the heat bonding is completed, the heat bonding module (B06) blows cooling gas to the heat bonding position of the film through the air hole to dissipate heat, and the film bonding assembly (3042) stops after moving along the Z direction.
