Abstract:
1. A bonding method comprising: (a) providing a bonding apparatus comprising a frame, a first feeding mechanism mounted on the frame, a second feeding mechanism mounted on the frame, and a bonding mechanism, the first feeding mechanism comprising a turntable capable of rotating relative to the frame, and a plurality of workpiece seats arranged on the turntable, the second feeding mechanism comprising a first carrier and a second carrier, the first carrier comprising a plurality of holding seats and the second carrier comprising a plurality of temporary holding seats, wherein the first carrier is capable of rotating to stack on the second carrier, the bonding mechanism is movably mounted on the frame to correspond to the workpiece seats or the second carrier; (b) mounting eligible first workpieces on the first feeding mechanism at a position being measured; (c) mounting second workpieces on the second feeding mechanism, the second workpieces arranged as a group attached on one protecting film; (d) separating the protecting film from the second workpieces and removing the second workpieces from the first carrier to the second carrier; (e) picking up one of the second workpieces by the bonding mechanism; (f) selecting an eligible second workpiece after determining a position of the selected second workpiece being measured and comparing positions of the first workpiece and the second workpiece to put the second workpiece in a desired position; (g) bonding the first workpiece and the second workpiece together by the bonding mechanism; (h) unloading the bonded first workpiece and second workpiece from the bonding apparatus; (i) turning off the bonding apparatus if no more first workpiece and second workpiece need to be bonded together or repeating at least part of above steps and mounting the first workpieces on the first feeding mechanism if more first and second workpieces need to be bonded together; if more first and second workpieces need to be bonded together and one or more eligible second workpiece are on the second carrier, repeating steps (b) and (e) to (h); if more first workpiece and second workpiece need to be bonded together and no eligible second workpieces are on the second carrier, repeating steps (b) to (h) and the removing ineligible second workpiece from the second carrier.
