Abstract

The utility model discloses a level correction device used for a lead frame. The level correction device used for the lead frame comprises a slope sliding bar (1) which is fitted in a female mould plate and can slide up and down; the slope of the slope sliding bar is matched with a slope gasket (2); the slope gasket is provided with a flat gasket (3) in a matched manner; the flat gasket is provided with a correction block (4) in a matched manner, wherein the correction block (4) is used for correcting the level bending of the lead frame; and the flat gasket, the slope gasket and the slope sliding bar are fixedly connected onto the correction block sequentially through screws. With the level correction device used for the lead frame of the utility model adopted, under a situation that pieces are not disassembled, a tensioning bolt and a jacking bolt can be adjusted to make the slope sliding bar to slide up and down in the female mould plate and to cooperate with the slope gasket, so that position change of the correction block can be driven, and therefore, the level correction device used for the lead frame is advantageous in convenient and flexible adjustment, no need for disassembling the gasket, improvement of work efficiency and labor-saving property; a spring enables enough level movement quantity for the slope sliding bar, and the slope angles of the slope sliding bar and the slope gasket are small angles, and therefore, the position of the correction block can be adjusted finely, and thus, the level correction device used for the lead frame is further advantageous in more accurate adjustment.

Description

For the rectification device of lead frame
Technical field
The utility model relates to the lead frame mould for semiconductor packages, relates in particular to the rectification device for lead frame.
Background technology
Lead frame is as the chip carrier of integrated circuit, it is a kind of electrical connection that realizes chip internal circuit exit and outer lead by means of bonding material (spun gold, aluminium wire, copper wire), form the key structure part of electric loop, it has played the function served as bridge being connected with outer lead, in the semiconductor integrated block of the overwhelming majority, all needing to use lead frame, is basic material important in electronics and information industry.Lead frame is to be formed by copper strips compacting, lead frame out-of-flatness after compacting, there will be buckling, the namely bending of vertical direction, need to be through overcorrection, the buckling of lead frame can solve by levelling machine before punching press, easily in punching course, produce the bending that transverse curvature is horizontal direction, for this horizontal curvature is corrected, need to use means for correcting to proofread and correct the position that occurs horizontal curvature, and existing means for correcting comprises correcting block and pad with boss, correcting block and pad are directly fixedly connected in concave template, can not adjust, but in actual production, each lead frame occurs that the position of horizontal curvature is different, need to unload lower gasket or increase pad adjust correcting block position to guarantee accurate correction, operation inconvenience, affect operating efficiency, expend a large amount of man power and materials, increase the die debugging time, affect product delivery date.
Utility model content
The technical problems to be solved in the utility model is existingly to adjust inconvenient quick for the means for correcting of proofreading and correct lead frame horizontal curvature, increase the die debugging time, affect operating efficiency, provide a kind of conveniently for the rectification device of lead frame for this reason.
The technical solution of the utility model is: for the rectification device of lead frame, it comprises and fits in the inclined-plane slide bar that can slide up and down in concave template, on the inclined-plane of described inclined-plane slide bar, be combined with inclined-plane pad, on described inclined-plane pad, be combined with flat pad, the adaptive correcting block of proofreading and correct lead frame horizontal curvature that is useful in described flat pad, described flat pad, inclined-plane pad and inclined-plane slide bar are fixed on correcting block by screw successively.
The improvement of such scheme is that between described inclined-plane slide bar and concave template, adaptation has spring.
The slide bar of inclined-plane described in such scheme is connected on concave template by tightening bolt is dismountable, between inclined-plane slide bar and concave template, is provided with puller bolt.
The angle of inclination, inclined-plane of the slide bar of inclined-plane described in such scheme is 1 °-5 °.
The beneficial effects of the utility model are in the situation that not dismantling part, by adjusting strain and puller bolt slides up and down inclined-plane slide bar in concave template and with the change in location that coordinates and then drive correcting block of inclined-plane pad, easy to adjust flexible, without dismounting pad, improve operating efficiency, saved manpower; The effect of spring is to give inclined-plane slide bar enough horizontal anomalous movement amounts, and the angle of inclination of inclined-plane slide bar and inclined-plane pad is low-angle, can finely tune the position of correcting block, adjusts more accurate.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram;
In figure, 1, inclined-plane slide bar, 2, inclined-plane pad, 3, flat pad, 4, correcting block, 5, spring, 6, tightening bolt, 7, puller bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises and fits in the inclined-plane slide bar 1 that can slide up and down in concave template, on the inclined-plane of described inclined-plane slide bar, be combined with inclined-plane pad 2, on described inclined-plane pad, be combined with flat pad 3, the adaptive correcting block 4 of proofreading and correct lead frame horizontal curvature that is useful in described flat pad, described flat pad, inclined-plane pad and inclined-plane slide bar are fixed on correcting block by screw successively.
Inclined-plane slide bar specifically can be fastened on concave template by tightening bolt 7 and puller bolt 6, in the female blind hole of the upper surface of inclined-plane slide bar processing belt, tightening bolt adaptation wherein, puller bolt is for being fixed inclined-plane slide bar position with tightening bolt, one end of puller bolt is fixed on concave template, and the other end holds out against the upper surface of inclined-plane slide bar.Certain the utility model can also adopt alternate manner to connect inclined-plane slide bar and can on concave template, slide, such as slide rail type.
The utility model preferably between inclined-plane slide bar and concave template adaptation have spring 5, spring can give inclined-plane slide bar enough activities, increases the space of inclined-plane slide bar, also can not account for the space between inclined-plane slide bar and concave template while adjustment at ordinary times.
Inclined-plane slide bar and the with it angle of inclination of the inclined-plane pad of cooperation are preferably 1 °-5 °, because low-angle can be finely tuned the position of correcting block, operate more accurate.This angle of inclination is with respect to installed surface namely the vertical plane in Fig. 1, and in the time that installation site changes, angle of inclination also changes datum line thereupon.
When use, unscrew puller bolt and tightening bolt, inclined-plane slide bar slided up and down on concave template, and then drive inclined-plane pad, flat pad to the left motion shown in figure, thus adjust correcting block stretch into through the degree of depth of lead frame.Do not need in process of production to dismantle mould and just can adjust, simple and efficient.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
