Technical Field

[0001] This utility model relates to a lead bending fixture for metal flat packages of hybrid integrated circuits. Background Technology

[0002] Currently, most lead wire bending fixtures use two metal fixed molds to clamp the lead wire, and then use metal rods or metal blocks to apply force to bend the lead wire.

[0039] like Figure 1-7 As shown, the lead bending fixture for the hybrid integrated circuit metal flat package of this embodiment includes a clamping fixture 4; an upper movable mold 3 is movable below the clamping fixture 4, which moves up and down to facilitate the placement, bending and removal of the integrated circuit.

[0040] The lower fixed mold 2 is fitted below the upper movable mold 3;

[0041] The lower fixed mold 2 and the upper movable mold 3 are used to clamp the integrated circuit component 22;

[0042] A side insertion hole D13 is provided horizontally in the upper movable mold 3;

[0043] A bent bracket 5 is inserted into the side socket D13;

[0044] A pressing roller 19 is provided on the lower side of the bending bracket 5 for pressing down the lead wire, which facilitates the fixed connection. Its rolling setting reduces friction, thereby reducing wear on the lead wire.

[0045] An extended hollow column C21 is provided on the top surface of the clamping fixture 4; it serves as a guide.

[0046] A screw hole C14 is provided on the top of the upper movable mold 3;

[0047] An upper connecting bolt 6 passes underneath the extended hollow column C21;

[0048] The upper connecting bolt 6 is threaded into the upper screw hole C14 to achieve connection and support. By adjusting the bolt screw length, it can meet the needs of integrated circuits of different heights.

[0049] A base component 1 is provided below the fixed mold 2 to serve as a fixed support.

[0050] As a specific technological innovation, a lower mold stop 8 is provided in the middle of the base component 1; a lower mold connecting hole B9 is provided at the lower mold stop 8; thereby achieving positioning and avoiding obstruction.

[0051] A base connection hole A7 is provided on the base component 1;

[0052] The clamping fixture 4 is a gantry frame, which facilitates the assembly and disassembly of the upper mold. The bottom of the gantry frame is provided with a bottom threaded hole A20 that is connected to the base connection hole A7 by bolts.

[0053] The bottom of the lower fixed mold 2 is set in the base connection hole A7;

[0054] The bottom surface of the lower fixed mold 2 is provided with a lower screw hole B12 that is connected to the lower mold connection hole B9 by bolts.

[0055] A lower positioning stop 10 is provided on the upper surface of the lower fixed mold 2 for positioning the lower part of the integrated circuit component 22. Lower lateral grooves 11 are provided on both sides of the lower positioning stop 10 for exposing the leads of the integrated circuit component 22.

[0056] A process groove 15 is provided on the top of the upper movable mold 3;

[0057] An upper positioning stop 16 is provided at the bottom of the upper movable mold 3;

[0061] The crossbar D18 is used to insert into the side insertion holes D13 from both sides respectively.

[0062] The downward roller 19 is located at the corner of the crossbar D18 and the inclined hand holder 23, so that the crossbar D18 can be inserted into the hole as much as possible. The inclined hand holder 23 is set at an angle, thereby generating downward and inward component forces, preventing the crossbar D18 from moving outward during the downward pressing process, thus keeping the force inward at all times. At the same time, it is convenient for people to operate with both hands.

[0063] The working principle is as follows: The lower fixed mold 2 and the clamping fixture 4 are installed on the base component 1. The upper movable mold 3 is installed on the clamping fixture 4 through the upper connecting bolt 6, and its range of motion is adjusted. The integrated circuit component 22 is placed in the lower positioning stop 10, and the crossbar D18 of the bending bracket 5 is inserted into the side insertion hole D13. Both hands press down on the inclined hand-held brackets 23 on both sides, and exert force downward together, so that the downward pressing roller 19 presses down on the lead wire, thereby realizing bending. It is convenient, flexible, and versatile, and is suitable for manual small-batch processing of lead wires.
