Description

Technical Field

[0001] The utility model belongs to the technical field of heading machine equipment, and in particular relates to a semiconductor lead heading mechanism. Background Art

[0002] The diode lead is a metal conductor that connects the diode chip to the external circuit. It is usually made of metal materials with good conductivity. The diode lead plays the role of transmitting current and signals. Through the diode lead, the diode can be connected to the pads on the circuit board, the pins of other devices, etc., to achieve circuit conduction and function realization. It is an important "bridge" for the diode to interact with the external circuit.

[0003] At present, the end forming of some diodes is mostly formed by mechanical stamping, such as using a bumper to align with the clamped lead end to impact and extrude it. In order to ensure the yield rate of the end forming, the bumper is usually used to quickly impact the lead end several times, so that the lead end is gradually formed;

[0004] Although copper leads have good ductility, the impact force cannot be controlled well during the impact process, resulting in deformation of the end shape and cracking of the edges, which reduces the yield rate of the leads. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a semiconductor lead header mechanism for solving the problem of low lead yield.

[0006] The utility model solves the above technical problems with the following technical solutions: a semiconductor lead-tipped mechanism, comprising:

[0007] a base, the base being configured to reciprocate along a first direction;

[0008] A slider, wherein the slider is slidably connected to the base along a second direction perpendicular to the first direction;

[0009] At least two impact heads, the impact heads are sequentially mounted on the slider along the second direction, and a molding groove is formed on the surface of one of the impact heads;

[0010] The drive cylinder has an output rod end connected to the slider and is used to drive the slider to reciprocate along the second direction.

[0011] Compared with the prior art, the above technical solution has the following beneficial effects:

In this way, the impact head with the forming groove is first aligned with the lead end, and the base as a whole drives the impact head to reciprocate along the first direction to hit the lead end into a lump. After that, the driving cylinder is moved to align the other impact head with the lead end, and then the lead end is flattened and hit. In this way, the lead end can be better flattened without deformation or cracking, thereby improving the yield rate.

[0015] In one embodiment, a dovetail groove is provided in the base, and the slider is configured as a dovetail-type slider matching the dovetail groove.

[0016] In one embodiment, a groove is formed on the inner wall of the dovetail groove along the second direction, the groove is filled with a pressure strip, and at least one adjusting screw penetrating the groove is connected to the base.

[0017] In one embodiment, a positioning groove for positioning the impact head is provided on the surface of the sliding block, and the positioning groove is a strip-shaped positioning groove provided along the second direction.

[0023] In one embodiment, a second waist-shaped hole is formed on the connecting seat perpendicular to the second direction to adjust the alignment center of the impact head. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Example

[0044] like Figure 1-3 As shown, the semiconductor lead heading mechanism provided by the utility model comprises: a base, a slider, two impact heads and a driving cylinder.

[0045] The base is used to reciprocate along a first direction, specifically, the first direction is a lateral horizontal direction, and the slider is slidably connected to the base along a second direction perpendicular to the first direction, wherein the second direction is a vertical direction perpendicular to the horizontal, that is, the slider can slide in the vertical direction, and the two impact heads are sequentially installed on the slider along the second direction, one of the impact heads has a molded groove on its surface, and the impact surface on the other impact head can be set to different shapes such as grooves and planes according to actual needs, and the molded groove is specifically opened on the impact surface of the impact head, and the first direction is perpendicular to the impact surface, and the output rod end of the driving cylinder is connected to the slider for driving the slider to reciprocate along the second direction, and the output rod of the driving cylinder can drive the slider to reciprocate in the vertical second direction, and selectively align the two impact heads with the lead end. In this embodiment, the impact head with the molded groove first collides with the lead end, and then the other impact head collides with the lead.

[0046] The overall base reciprocates along a first direction, so that the impact head installed on the slider connected to the base can play a heading role, and a driving cylinder is set in a second direction perpendicular to the first direction to drive the slider to reciprocate, so that the two impact heads set along the second direction can respectively contact the lead end. In this way, the impact head with the forming groove is first aligned with the lead end, and the base as a whole drives the impact head to reciprocate along the first direction to hit the lead end into a lump. After that, the driving cylinder is moved to align the other impact head with the lead end, and then the lead end is flattened and hit. In this way, the lead end can be better flattened without deformation or cracking, thereby improving the yield rate.

[0047] In one embodiment, it further comprises a protective cover, which is arranged outside the driving cylinder, and a limiting rod is screwed on the protective cover along the second direction, and the limiting rod is used to limit the output rod of the driving cylinder;

[0048] On the one hand, the protective cover can play the role of protecting the driving cylinder. At the same time, a limit rod can be set on the protective cover. The limit rod can be a screw rod, which is threaded with the protective cover. The limit rod is coaxially arranged with the output rod of the driving cylinder. The driving cylinder can adopt a double-rod driving cylinder, one end of which is fixedly connected to the slider and the other end is opposite to the limit rod. The limit rod can limit the maximum displacement range of the output rod of the driving cylinder.

[0049] Specifically, a dovetail groove is provided in the base, and the slider is configured as a dovetail-type slider matching the dovetail groove. Through the configuration of the dovetail groove and the dovetail-type slider, the slider can be kept moving in the second vertical direction to avoid shaking.

[0050] In order to make the tightness of the dovetail groove and the dovetail slider adjustable, a groove is opened on the inner wall of the dovetail groove along the second direction, and the groove is filled with a pressure strip. At least one adjusting screw that passes through the groove is connected to the base, and the end of the adjusting screw extends into the groove and can abut against the surface of the pressure strip. By screwing the adjusting screw in and out, the pressure strip can be pressed against the surface of the slider or loosened, thereby adjusting the tightness between the slip ring and the dovetail groove.

[0051] The surface of the slider is provided with a positioning groove for positioning the impact head, and the positioning groove is a strip positioning groove opened along the second direction. The positioning groove is set as a vertical strip positioning groove, so that the impact head can be further vertically adjusted in this direction, while the horizontal direction is restricted by the positioning groove and no deviation occurs.

[0052] In this embodiment, the impact head includes: a base and a collision block.

[0053] An extension portion is formed on one side of the base, and a fastener for fixing the connection is passed through the extension portion. The fastener can be a screw, and the base is tightened in the positioning groove by the screw. The impact block is installed on the top of the base so that the impact block faces the lead end.

[0054] The extension portion is provided with a first waist-shaped hole arranged along the second direction for passing the fastener. The arrangement of the first waist-shaped hole enables the positions of the two impact heads to be adjusted in the second vertical direction.

[0055] A connecting seat is provided on the side of the base away from the impact head, and the connecting seat is detachably connected to the base. A positioning connecting handle is provided on the surface of the connecting seat along the first direction. The setting of the positioning connecting handle can make the connection between the entire base and the external driving device of the horizontal driving base more accurately positioned.

[0056] A second waist-shaped hole is provided on the connecting seat perpendicular to the second direction to adjust the alignment center of the impact head;

[0057] Specifically, the connecting seat has a transverse dovetail-shaped protrusion, and a groove matching the dovetail-shaped protrusion is provided on the back of the base, so that the connecting seat is connected to the base through the dovetail-shaped protrusion, thereby ensuring stability in the first direction and avoiding deviation in the first direction, and being able to achieve horizontal movement perpendicular to the second direction and matching the length direction of the waist-shaped hole, thereby facilitating adjustment of the base and the connecting seat in this direction.

[0058] Since the impact head is installed in the positioning groove, the impact head can be adjusted in the second vertical direction, and the second waist-shaped hole on the connecting seat is opened in a horizontal direction perpendicular to the second direction, so that the base as a whole can be adjusted in a horizontal direction and perpendicular to the positioning groove, and then the position of the impact head can be adjusted in the horizontal direction, which is convenient for aligning the impact head with the lead end.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
