The seam shape that frame interlocks between pin is consistent, which holds up lead frame using supporting bar, it is difficult to make lead frame
Uniform stressed, for the lead frame of the multiple rows of 300X100 of ultra-wide, since encapsulating products density is very big in unit area, lead frame
Frame is very thin, hold it is a little very small, if using above-mentioned feeding frame can make lead frame deformation even crack, it is difficult to throw
It puts, positioning is inaccurate, loading efficiency is low.
Utility model content
The technical problems to be solved in the utility model is that the existing feeding device for ultra-wide multi-row lead frame frame can make
Lead frame deforms, and positioning is inaccurate, loading efficiency is low, provides a kind of ultra-wide multi-row lead frame frame abnormity holding frame feeding therefore
Device.
The technical solution of the utility model is：Ultra-wide multi-row lead frame frame abnormity holding frame feeding device, it includes at least one
A lower holding frame, the interior of the lower holding frame peripherally offer recessed channel, and bottom is connected with several horizontal subiculums in the female slot
Item is fitted with holding frame in the female slot, be connected in the upper holding frame with the horizontal lower corresponding horizontal upper supporting bar of supporting bar,
The upper holding frame is connected with lower holding frame by being located at the detachable mechanism of frame.
The depth of recessed channel described in said program is consistent with the overall height of lead frame and upper holding frame.
Horizontal lower supporting bar and horizontal upper supporting bar are special-shaped supporting bars described in said program.
The improvement of said program is to be connected with handle on one of frame of the lower holding frame.
Detachable mechanism described in said program is to be located at upper holding frame and the magnet of the magnetic cooperation in lower holding frame respectively
And metal gasket.
Detachable mechanism described in said program further includes the frame positioned at horizontal lower supporting bar and/or horizontal upper supporting bar end
Frame locating pin.
Being further improved for said program is that supporting bar and/or the horizontal end of supporting bar down offer frame and determine in the level
Position hole 9.
The beneficial effects of the utility model are that recessed channel can carry out horizontal location to ultra-wide multi-row lead frame frame, and can
To hold up the periphery of ultra-wide multi-row lead frame frame, the lower supporting bar of level and horizontal upper supporting bar can be more to ultra-wide from upper and lower both direction
Row lead frame forms clamping, ensures that its whole uniform force is indeformable.

Specific embodiment
As shown in Figure 2,3, the utility model includes at least one lower holding frame 1, and the interior of lower holding frame peripherally offers
Recessed channel 2, bottom is connected with several horizontal lower supporting bars 3 in the female slot, and holding frame 4 is fitted in the female slot, described
The corresponding horizontal upper supporting bar 5 of supporting bar under being connected in upper holding frame and being horizontal, the upper holding frame and lower holding frame are by being located at frame
Detachable mechanism connection.
The utility model is described further with reference to the accompanying drawings and embodiments.
Embodiment 1：Ultra-wide multi-row lead frame frame abnormity holding frame feeding device, it includes a lower holding frame, the lower holding frame
It is interior peripherally offer recessed channel, bottom is connected with several horizontal lower supporting bars in the female slot, adaptation in the female slot
There is upper holding frame, be connected in the upper holding frame and the horizontal lower corresponding horizontal upper supporting bar of supporting bar, the upper holding frame and lower holding frame
It is connected by the detachable mechanism for being located at frame.The detachable mechanism can be the magnet 7 and metal gasket of magnetic cooperation
