Description
Technical field
The utility model relates to a kind of lead frame transverse curvature controllability means for correcting.
Background technology
As everyone knows, the height of semiconductor lead frame dimension precision requirement.Lead frame transverse curvature is one of important monitoring project of production process size.For ensureing framework production required precision, mould often adopts the techniques such as correcting block, to the part of product even certain specific dimensions correct.Correcting block technological principle: correct punching press effect by the PUNCH correcting block 22 on mould and DIE correcting block 44, makes the lead-in wire 33 upwarped have a downward extruding, thus realizes product size and meet required precision scope, as shown in Figure 1.
Original use transverse curvature means for correcting, have employed the technique of installing correcting block on die socket.This production technology also exists some deficiency following:
(1) former technique is used on die socket and installs correcting block, and when mould is produced, lead frame transverse curvature can not adjust on lathe.By the relative altitude of correcting block on adjustment mould, operating efficiency can only be greatly reduced like this.
(2) original correcting block acts on lead frame, can leave certain technique impression.To product structure, performance within controlled range, certain impact can be there is for product appearance.
(3) it is comparatively wide that original correcting block acts on scope on framework, and the possibility affecting other sizes of framework is higher.
Utility model content
The purpose of this utility model solves the problem correcting lead frame transverse curvature.
The technical solution adopted in the utility model is: a kind of lead frame transverse curvature controllability means for correcting, comprise die socket 4 and the adjusting device be arranged in die socket 4 die head and means for correcting, described adjusting device comprises top shoe 2 and sliding block 3, sliding block 3 is connected with lateral adjustments screw 11 one end, and the fixed plate A 8 of the other end of lateral adjustments screw 11 is connected with fixed head B10; Described means for correcting comprises correcting block 1 and coordinating block 7, and correcting block 1 is connected with bottom die socket 4 by screw 6, correcting block 1 and top shoe 2 close contact, and coordinating block 7 is arranged on directly over correcting block 1; Described correcting block 1 working face is provided with some boss, and coordinating block 7 working face is provided with some grooves, and boss is corresponding with groove.
As further improvement of the utility model, top shoe 2 is tilting with the contact surface of sliding block 3.
As further improvement of the utility model, be hollow out in the middle of top shoe 2 and sliding block 3.
As further improvement of the utility model, between screw 6 and die socket 4 bottom surface, be provided with spring.
The beneficial effects of the utility model are: the utility model structure is reliable, and function admirable, has some advantage following:
(1) original correcting block is comparatively wide in framework active area, affects very large for properties of product, constructional appearance.Novel lead frame transverse curvature means for correcting directly acts on support lead, and the adverse effect brought for other aspect sizes of product is negligible;
(2) the utility model provides a kind of bearing calibration directly acting on support lead, decreases the influence factor of means for correcting for frame appearance;
(3) original correcting block is inlayed, be installed in mould, and when calibration result does not reach ideal effect, mould must unload equipment and carry out maintenance and debugging.The present invention directly provides a kind of means for correcting that can directly regulate on equipment, greatly improves operating efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of prior art.
Fig. 2 is schematic diagram of the present utility model.
Shown in figure: 1 correcting block, 2 top shoes, 3 sliding blocks, 4 die sockets, 5 springs, 6 screws, 7 coordinating blocks, 8 fixed plate A, 9 fixed head B, 11 lateral adjustments screws, 22PUNCH correcting block, 33 lead-in wires, 44DIE correcting block.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model detailed description of the invention is elaborated.
As shown in Figure 2, the present embodiment comprises die socket 4 and the adjusting device be arranged in die socket 4 die head and means for correcting, adjusting device comprises top shoe 2 and sliding block 3, sliding block 3 is connected with lateral adjustments screw (11) one end, and the fixed plate A 8 of the other end of lateral adjustments screw 11 is connected with fixed head B10; Means for correcting comprises correcting block 1 and coordinating block 7, and correcting block 1 is connected with bottom die socket 4 by screw 6, correcting block 1 and top shoe 2 close contact, and coordinating block 7 is arranged on directly over correcting block 1; Correcting block 1 working face is provided with some boss, coordinating block 7 working face is provided with some grooves, and boss is corresponding with groove, and top shoe 2 is tilting with the contact surface of sliding block 3, be hollow out in the middle of top shoe 2 and sliding block 3, between screw 6 and die socket 4 bottom surface, be provided with spring 5.
Correcting block 1 and coordinating block 7 mating reaction be mounted on stripper, by the adjustment of correcting block 1 for framework calibrated force size, thus realize the controllability of calibration result, the punching press of correcting block 1 pair of support lead corrects, by the mode of gravitation in release lead-in wire, to realize the correction of lead frame transverse curvature.
Top shoe 2 and sliding block 3 contact surface are designed to certain angle of inclination, thus realize the controllability of correcting block 1 height.Lateral adjustments screw 11 is connected with 3 sliding blocks, just can realize moving left and right of sliding block 3 by lateral adjustments screw 11, indirectly realizes the adjustment of top shoe 2 height.The mating reaction of fixed head a8 and fixed head b10, object is the movement limited in the horizontal direction of lateral adjustments screw 11, the lateral adjustments screw 11 be fixed just controls moving left and right of sliding block 3 by rotating, and fixed head a8 and fixed head b10 is fixed by screws on die socket 4.Screw 6 is threaded connection, fixed correction block 1, and spring 5 provides support power for screw 6, and after ensureing that correcting block 1 highly regulates, screw 6 is firm fixing by it.
Below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.
