Abstract
The invention discloses a kind of material loading framework for the lead frame with staggered pin, it comprises framework (1) and is fixed in two handles (5) outside framework (1) side, be provided with several in described framework (1) to be used for holding up the holding frame (6) with the lead frame of staggered pin, the horizontal pane line of described holding frame (6) is connected with holder bar, and described holder strip is consistent with the seam shape that lead frame interlocks between pin.The present invention is stretched into by the holder bar that the gap between the staggered pin of shape and lead frame is consistent and holds up lead frame between the staggered pin of lead frame die face utilance is improved, it is more steady that supporting plate makes lead frame place, four holding frames make doses larger, reach eight.
Description
Technical field
The present invention relates to material loading framework, particularly relate to a kind of material loading framework for the lead frame with staggered pin.
Background technology
At present, after IC semiconductor in road packaging process, because the structural design of lead frame is to the development of many row's multiple rows, and the width of lead frame is widened and is also had limitation, so just requiring that on the band of original width enable encapsulation is mostly is products, and the single spacing of product is less, closeer.The design of feeding device of lead frame is so just made to have come out gradually bottleneck, all have higher requirement to the design of lead frame, processing, quality, existing material loading of lead frame frame is more and more not suitable with the high speed development of the industry such as road encapsulation after IC semiconductor chip design, semiconductor.Existing material loading of lead frame shelf structure is single, and each loading efficiency is very low, each material loading lead frame quantity is few, it is low that mould enters a precision, and die face utilance is low, and traditional small lot material loading, encapsulation can not meet the production of client, skill upgrading and development.So rely on original simple material loading framework can not meet the development of many row's encapsulating moulds.
Summary of the invention
The problem to be solved in the present invention be existing material loading framework can only small lot material loading, die face utilance low, a kind of material loading framework for the lead frame with staggered pin is provided for this reason.
Technical scheme of the present invention is: a kind of material loading framework for the lead frame with staggered pin, it comprises framework and is fixed in two handles outside framework side, be provided with several in described framework to be used for holding up the holding frame with the lead frame of staggered pin, the horizontal pane line of described holding frame is connected with holder bar, and described holder strip is consistent with the seam shape that lead frame interlocks between pin.
The improvement of such scheme is described holding frame is four, framework quadrisection.
The improvement of such scheme is 2 the bracketing holder bars every bar horizontal pane line of described holder bar in holding frame being divided into 2 of positioning guidewire framework locate holder bar and being positioned at the bracketing lead frame inside location holder bar.
The improvement of such scheme be described holding frame the longitudinal frame line of every bar on be evenly connected with 2 and coordinate with the holder bar on holding frame two horizontal pane lines the supporting plate that lead frame is steadily placed respectively.
The improvement of such scheme is described holder bar is steel holder bar.
The improvement of such scheme is described supporting plate is steel supporting plate.
The improvement of such scheme be described holder bar by lining floating connection in holding frame.
The improvement of such scheme be described supporting plate by lining floating connection in holding frame.
Holding up lead frame between the staggered pin that the consistent holder bar in gap between the invention has the beneficial effects as follows by the staggered pin of shape and lead frame stretches into lead frame makes die face utilance improve, it is more steady that supporting plate makes lead frame place, four holding frames make doses larger, reach eight.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, two handles 5 that the present invention includes framework 1 and be fixed in outside framework 1 side, be provided with several in described framework 1 to be used for holding up the holding frame 6 with the lead frame of staggered pin, the horizontal pane line of described holding frame 6 is connected with holder bar, and described holder strip is consistent with the seam shape that lead frame interlocks between pin.
Described holding frame 6 can be one, two, four, preferably four, be uniformly distributed in framework 1, so once go up doses more, single can go up more than the eight ultra dense staggered lead frames of ultra-wide, framework less grid can certainly be separated into, more lead frame can be once held.
Because the product on lead frame is staggered Small Distance close-packed arrays, the holder bar of original shape just can not put in lead frame and hold up framework, if conventional design concept holder bar will be adopted just very narrow, does not have intensity and is not easy processing, modification etc.So holder strip adoption S type of the present invention, S type curve radian and the lead frame pin gap designed that is staggered is consistent.When lead frame is placed in the holding frame 6 of material loading framework, the holding frame at the two ends, left and right of lead frame respectively arranges a supporting plate 4 and helps out, like this could the strong and staggered lead frame of the picking-up of equilibrium.Be provided with two handles 5 in the active side of material loading framework, handle is connected on framework by handle connecting rod (handle connecting rod carries out the bending of 150 °, has conveniently held material loading framework), handle fixed block.
Described holder bar has 8 in each holding frame, and the horizontal up and down frame line of holding frame 6 distributes symmetrically and evenly in four or four.The horizontal frame line of holder bar in each holding frame is divided into the location of 2 positioning guidewire frameworks to hold in the palm bar 2 and is positioned at the bracketing holder bar 3 that 2 bracketing lead frames inside bar 2 are held in the palm in location.4 location holder bars 2 and 4 bracketing holder bars 3 are had like this in each holding frame.First by the locating pin on location holder bar 2, lead frame is located in use, therefore enter a precision high, bracketing holder bar 3 plays the effect holding up lead frame, prevents lead frame to be out of shape.Two of lead frame corrects on the supporting plate that is positioned over about holding frame on two longitudinal frame lines, avoids lead frame to bend like this.
Described holder bar and supporting plate 4 are all steels, and intensity is high, not frangibility.
Holder bar, supporting plate adopt with framework 1 that lining is floating type to be connected, there is the monolateral gap of about 0.2MM and upper and lower 0.1MM between holder bar and framework, lead frame and material loading framework that mismachining tolerance brings could be solved like this and a difficult problem is forbidden in the position that enters between material loading framework and diaphragm capsule.The present invention goes between material loading framework to solve the overall weight of material loading framework, groove can be alleviated when not affecting overall structure and the performance of material loading framework in the increase many places, the back side of material loading framework, effectively can alleviate the overall weight of material loading framework like this, for operator alleviates operating pressure, increase work efficiency.
