The invention discloses an automatic laminator which comprises a transplant jacking mechanism, a product positioning frame, a first discharging component, a second discharging component, a third discharging component, an edge covering and laminating mechanism, a conveying mechanism, a barcode scanning gun, a short-edge material laminating mechanical-arm component, a long-edge material laminating mechanical-arm component, a short-edge material peeling mechanism, a long-edge material peeling mechanism, a short-edge material detecting device, a long-edge material detecting device, a product short-edge camera positioning component, a product long-edge camera positioning component, etc., which are arranged on an operation table. Through the mutual coordination and match of the transplant jacking mechanism, the material peeling mechanisms, the laminating mechanical-arm components, the edge covering and laminating mechanism, the conveying mechanism, etc., the automatic laminator completes theprocess of feeding, positioning, material peeling, laminating, edge covering, discharging, etc. in order. The automatic laminator realizes the automatic laminating operation of products, reduces thelabor intensity of workers, shortens the laminating time, greatly improves the laminating precision and the laminating efficiency, and reduces the production cost.
