The automatic laminating machine according to claim 1, wherein the sheet material belt retracting mechanism comprises: The sheet material tape unwinding shaft, on which the rolled sheet material tape with sheet material unit is assembled and the sheet material tape is supplied externally; a sheet material belt take-up spool for rewinding the sheet material belt from which the sheet material unit has been stripped; and The sheet material belt conveying roller is arranged between the sheet material belt discharging shaft and the sheet material belt receiving shaft for pulling the sheet material belt to move, and the sheet material belt conveying roller includes: an upper drum, a middle drum and a lower drum, Wherein, the middle roller is driven to rotate by the sheet material belt driving member, and the sheet material belt with the sheet material unit output from the sheet material belt discharge shaft passes between the upper roller and the middle roller, and passes through the stripping member. The sheet material belt stripped of the sheet material unit passes between the middle drum and the lower drum and is wound onto the sheet material belt take-up shaft. 8. An automatic bonding method, characterized in that, utilizing the automatic bonding machine described in any one of claims 1 to 7 to carry out sheet-to-roll bonding, the bonding method comprises the steps of: separately supplying a web of sheet material with sheet units to be transferred and a web of base material for transferring said sheet units; Carrying out positioning detection on the sheet material belt and the base material belt with the sheet material unit respectively; Control the conveying speed of the sheet material belt and/or the base material belt according to the detection results of the positioning of the sheet material belt and the base material belt; Peel off the sheet unit to be transferred on the sheet material belt, so that the peeled sheet unit falls on the predetermined area of the base material belt; Pressure is applied to a predetermined area of the base material belt carrying the sheet material unit, so that the sheet material unit is attached to the predetermined area of the base material belt. 9. The automatic laminating method according to claim 8, wherein the positioning detection of the sheet material belt and the base material belt respectively comprises: Perform positioning detection with the front edge or rear edge of the sheet unit as the positioning detection point; and/or The positioning detection is carried out by using the positioning hole set on the side of the predetermined area on the base material belt as the positioning detection point. 10. The automatic laminating method according to claim 8, further comprising: laminating a protective film on the surface of the base material belt on which the sheet unit is pasted.
