Description
Technical Field
[0001] The present invention relates to the technical field of semiconductor packaging, and in particular to an adaptable and adjustable preheating plate for semiconductor packaging. Background Art
[0002] During semiconductor production, semiconductors need to be plastic-sealed. An automatic sheet arranging machine is required for plastic sealing. The automatic sheet arranging machine is equipped with a preheating plate, which is installed on the loading rack of the automatic sheet arranging machine. The preheating plate preheats the product frame, and the loading arm structure drives the product frame to move and arrange the product frame into the preheating plate.

The present invention adopts a frame assembly, and integrates structures such as a preheating assembly, a manipulator assembly and a pressure plate assembly through a bottom plate, a side plate and a movable plate, so that the lead frame can be completed in the frame assembly during the preheating process, reducing the stroke of the manipulator assembly and avoiding heat loss; the movable plate of the present invention can be movable relative to the side plate, and when grabbing a workpiece, the movable plate can drive the manipulator assembly to move above the lead frame, and then grab the lead frame, and the entire grabbing process cycle is short, thereby improving work efficiency; the pressure plate assembly and the preheating assembly of the present invention are both provided with a heat insulation plate, which can reduce unnecessary heat exchange and further improve the heat preservation effect of the lead frame.
[0004] However, the preheating plate is generally provided with a side fixed groove structure.
