Description
Technical field
The utility model relates to the technical field of QFN encapsulation, is specially a kind of plastic packaging material stock shelf of QFN packaging technology.
Background technology
Existing QFN packaging technology is manual material loading, is about to cylindrical plastic packaging material and puts into plastic package die one by one with hand, and then single through the molding press plastic packaging, it makes that the operating efficiency of molding press is low.
Summary of the invention
To the problems referred to above, the utility model provides a kind of plastic packaging material stock shelf of QFN packaging technology, and it makes the high efficiency of molding press.
A kind of plastic packaging material stock shelf of QFN packaging technology; Its technical scheme is such: it comprises top panel, lower panel, front panel, rear board; It is characterized in that: the upper surface of said top panel is evenly equipped with eight and goes up material through hole; The upper surface of said lower panel is evenly equipped with eight following material through hole; The upside of said front panel, rear board is fastenedly connected the forward and backward side of said top panel respectively, and the downside of said front panel, rear board has axially extending bore, and the both sides, bottom of said lower panel have major axis to through hole; Two fixed axis run through the major axis of axially extending bore, lower panel of said front panel respectively successively to the axially extending bore of through hole, rear board; The rear end face of said lower panel has the spring blind hole, and spring is installed in the said spring blind hole and its rear side is mounted on the front end face of said rear board, and the rear end face of said rear board is connected with operating grip; Said top panel is supported on the upper surface of said lower panel; Eight eight following material through hole going up material through hole and said lower panel of said top panel are corresponding one by one, and there is fixedly axial spacing in said one to one center of going up material through hole, following material through hole, and the distance that said spring is stretched in said spring blind hole outward equals said fixedly axial spacing.
It is further characterized in that: the rear end face of said rear board has the handle installing blind, and the front end of said operating grip is plugged in the said handle installing blind.
After adopting the utility model, successively eight columniform plastic packaging materials are put into eight respectively and go up material through hole, because there is fixedly axial spacing in said one to one center of going up material through hole, following material through hole; So eight plastic packaging materials are placed in the said top panel, directly eight plastic packaging materials are put into plastic package die simultaneously after the plastic package die die sinking, at this moment; Only need to promote operating grip; Make length of spring compressed, thus make saidly one to one go up material through hole, the center of material through hole overlaps down, this moment, eight plastic packaging materials can fall into plastic package die from the following material through hole of correspondence; It has saved the operating time; Utilize the time of the moulding press course of work, simultaneously manually put into this stock shelf to eight plastic packaging materials, it makes the high efficiency of molding press.
