Abstract
This utility model is lead frame feeding guide, belongs to semiconductor integrated circuit lead frame former.Its objective is to prevent lead frame blanking process to be deformed, it is ensured that punching quality, improve the quality product rate of product.This utility model is made up of guide and clamping element, and guide includes rail body and guide pad, and rail body is made up of guide rail upper plate and guide rail bottom plate, and guide pad is arranged on guide rail upper plate, guide rail bottom plate float support material strip.The clamping element is the gentle pawl of clamp, and clamp is arranged on above and below rail body, by gas pawl drive work.The guiding of adjustment guide pad scalable lead frame material strip so as to which, clamp clamps material strip frame nonfunctional area in feeding process with mould relative position accurately, in X direction to die entrance feeding, reciprocation cycle work.This utility model is used for the making of semiconductor integrated circuit lead frame, is particularly suited for thin material, the making of wide material lead frame.
Description
Technical field
This utility model is related to semiconductor integrated circuit lead frame former, and specifically a kind of lead frame feeding is led
Rail.
Background technology
Lead frame is the chip carrier of semiconductor integrated circuit, is the crucial knot for realizing circuit electrical connection inside and outside chip
Component, the making of lead frame have two kinds of pressing and etching method, and punch forming operation is to cut the rolling semi-finished product after plating
Break as strip finished product, as lead frame is towards material is wider, thinner, multiple rows of, high foot position direction is developed, former feeding guide structure
Can not meet requirement, it is easy to cause lead frame to deform, such as：Draw angular variation, tilting, slide glass skew, inclination etc., serious shadow
Product quality is rung, therefore pole need to be improved.
The content of the invention
For the problem for avoiding existing feeder equipment from existing, this utility model offer is a kind of to ensure product quality well
Lead frame feeding guide.
The technical solution of the utility model is as follows：Lead frame feeding guide includes guide and clamping element, the guiding
Part is rail body and guide pad, and rail body is made up of guide rail upper plate and guide rail bottom plate, and guide pad is arranged on guide rail upper plate
On, guide rail bottom plate float support lead frame material strip, the clamping element are the gentle pawl of clamp, and clamp is arranged in rail body
Side and lower section, adjust the guiding of guide pad scalable lead frame material strip so as to accurate with mould relative position in feeding process
Really, clamp clamps the frame of lead frame material strip, carries out feeding according to the feeding step for arranging.
The beneficial effects of the utility model are as follows：1st, lead frame material strip is by guide rail bottom plate float support, anti-stopping materials strip
The deformation that feeding interval causes because of height, change in location in feeding process, it is ensured that material strip is accurate in Z-direction position；By
Make material strip corresponding with die entrance position in the adjustment effect of guide pad, it is ensured that the position in material strip y-axis direction is accurate；Due to folder
The clamping action of pincers, it is ensured that material strip is in the x-direction to mould feeding, it is therefore prevented that the issuable deformation of lead frame, therefore ensure
The shape of product, the correctness of size, improve the qualification rate of product；2nd, as the position folded by clamp is the frame of material strip
Nonfunctional area, it is to avoid the deformation of functional areas, is conducive to improve product quality；3rd, structural framing is exquisite, low cost of manufacture.

Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings, and as shown in Figure 1 and Figure 2, lead frame feeding is led
Rail includes guide and clamping element, and the guide is rail body 2 and guide pad 1 and 7, and rail body 2 is by 6 He of guide rail upper plate
Guide rail bottom plate 8 is constituted, and guide pad 1 and 7 is arranged on guide rail upper plate 6,8 float support lead frame material strip 4 of guide rail bottom plate,
Guide pad 1 and 7 is to adjust material strip 4 and die entrance position, it is ensured that material strip is accurate in the position in y directions.The clamping element bag
5 gentle pawl 3 of clamp is included, clamp there are upper and lower two, clamp frame nonfunctional area of the position for material strip 4, driven along X side by gas pawl 3
To die entrance feeding, return when clamp unclamps, reciprocation cycle realizes automated production.Fig. 4 is the three-dimensional knot of this utility model
Structure has marked three-dimensional and component names with reference to figure, in figure.
Gas pawl of the present utility model, clamp are finished parts, and rail body is metalwork.
