For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example like Figure 1-3 As shown, the diode lead bending mechanism provided by this utility model includes: a driving device 1, a first transmission component 2, a second transmission component 3, a bending component 5, and a bending rod 6.

[0025] The driving device 1 includes a driving cam through which other driving rods pass and drive the driving cam to rotate. The driving cam has a raised point on its circumferential surface, and the first end of the first transmission member 2 abuts against the circumferential surface of the driving cam.

[0026] The second end of the first transmission component 2 is provided with a wedge block 4. The first end of the second transmission component 3 abuts against the inclined surface of the wedge block 4. When the high point of the driving cam contacts the first transmission component 2, it drives the wedge block 4 to move. The inclined surface of the wedge block 4 drives the second transmission component 3 to move, thereby realizing the transmission of driving force.

[0027] The bending component 5 is installed on the second end of the second transmission component 3. The wire clamping module 7 is located below the bending component 5. The length direction of the wire clamping module 7 is parallel to the length direction of the second transmission component 3. The bending rod 6 is vertically inserted through the bending component 5. The bottom end of the bending rod 6 is located at the opening and closing position of the wire clamping module 7. The bending rod 6 reciprocates along the opening and closing direction of the wire clamping module 7 as driven by the second transmission component 3. The opening and closing direction of the wire clamping module 7 is the direction of movement of the wire clamping modules 7 towards or away from each other, and the length direction of the wire clamping module 7. The reciprocating movement of the bending rod 6 is used to bend the wire extending out of the wire clamping module 7.

[0028] The driving force of the drive device 1 is transmitted sequentially through the first transmission component 2 and the second transmission component 3. The position of the bending component 5 relative to the wire clamping module 7 is adjusted by the bending component 5. The bending rod 6 on the bending component 5 moves back and forth through the second transmission component 3. The bending rod 6 can bend the end of the wire clamping module, thereby achieving rapid forming of the lead wire end and improving the overall lead wire forming efficiency.

[0029] Specifically, the first transmission component 2 includes two first positioning seats 201 and a first transmission rod 202. The first positioning seats 201 are fixed on the machine base of the heading machine, and the first transmission rod 202 is slidably connected in the first positioning seats 201. The first end of the first transmission rod 202 is rotatably connected to a first roller 205. The circumferential surface of the first roller 205 abuts against the circumferential surface of the drive cam. The drive cam contacts the first transmission rod 202 through the first roller 205, ensuring that the frictional force between them is small. The first transmission rod 202 can be arranged on the side of the machine base.

[0030] To ensure that the first transmission component 2 is always in contact with the drive cam, the first transmission component 2 includes a first reset component 203, which is sleeved on the first transmission rod 202. The first reset component 203 can be implemented by a spring. The first transmission rod 202 is provided with a positioning screw 204. One end of the first reset component 203 abuts against the positioning screw 204, and the other end abuts against the first positioning seat 201, for pushing the first transmission rod 202 toward the drive device 1. The spring can be a compression spring or a tension spring, and its elastic force is sufficient to pull the first transmission rod 202 toward the drive cam.

[0031] In this embodiment, the second transmission component 3 includes: a second positioning seat 301 and a second transmission rod 302.

[0032] The second positioning seat 301 is disposed on the heading machine platform. Similarly, the second positioning seat 301 has the same function as the first positioning seat 201, which serves as a limit and controls the movement direction of the first transmission rod 202. The second transmission rod 302 is slidably connected in the second positioning seat 301. The second transmission rod 302 is disposed parallel to the wire clamping module 7. The first end of the second transmission rod 302 is rotatably connected to the second roller 304. The circumferential surface of the second roller 304 abuts against the inclined surface of the wedge block 4. The bending member 5 is disposed on the second transmission rod 302. By setting the second roller 304, the frictional force between the second transmission rod 302 and the first transmission rod 202 is reduced.

[0033] In this embodiment, a second reset member 303 is also included. One end of the second reset member 303 is connected to the second end of the second transmission rod 302, and the other end is connected to the heading machine platform. It is used to pull the second transmission rod 302 toward the side of the wedge block 4 away from its inclined surface. Specifically, the side of the wedge block 4 away from its inclined surface pulls the second roller 304 on the first end of the second transmission rod 302 against the inclined surface of the wedge block 4, ensuring that the second roller 304 is always in contact with the inclined surface of the wedge block 4, and ensuring that the driving force of the first transmission rod 202 is always transmitted to the second transmission rod 302 through the inclined surface of the wedge block 4.

[0034] To facilitate the position adjustment of the bending component 5, a waist-shaped hole 8 is provided on the bending component 5 along its length direction. The bending component 5 is connected to the second transmission rod 302 through the waist-shaped hole 8. Specifically, after fasteners such as bolts pass through the waist-shaped hole 8, they are connected to the second transmission rod 302 to fasten the bending component 5 to the second transmission rod 302. The waist-shaped hole 8 facilitates the adjustment of the bending machine's position on the second transmission rod 302.

[0035] In this embodiment, as Figure 3 As shown, the wire clamping module 7 includes two wire clamping blocks 701 arranged opposite to each other and an adjustment component 702.

[0036] Two clamping blocks 701 are arranged opposite each other and clamp the wire when they are closed together. One of the clamping blocks 701 is installed in the adjusting component 702, which is used to adjust the distance between the clamping block 701 and the other clamping block 701. Specifically, the wire clamping block 701 connected to the adjusting component 702 is the first wire clamping block 701, and the other wire clamping block 701 is the second wire clamping block 701. The first wire clamping block 701 is a fixed wire clamping block 701, and the second wire clamping block 701 is a movable wire clamping block 701. By controlling the movement of the second wire clamping block 701 to approach or move away from the first wire clamping block 701, the wire can be clamped and released. The second wire clamping block 701 can be driven by other drive mechanisms in the heading machine, which will not be described in detail here.

[0037] Specifically, the adjustment assembly 702 includes: an adjustment seat 7021, a snap-fit ​​block 7023, an adjustment block 7024, and an adjustment bolt 7025.

[0038] The adjusting seat 7021 is fixed on the machine table of the heading machine. The adjusting seat 7021 has a groove 7022. The size of the groove 7022 is larger than that of the wire clamping block 701. The wire clamping block 701 is disposed in the groove 7022.

[0039] The snap-fit ​​block 7023 is matched and snapped into the groove 7022 on one side of the wire clamping block 701 to fix the side position of the wire clamping block 701. The adjusting block 7024 is disposed at the end of the snap-fit ​​block 7023 away from the other snap-fit ​​block 7023. The adjusting block 7024 is used to fix the tail position of the wire clamping block 701. The size of the adjusting block 7024 is adjustable to adjust the position of the wire clamping block 701. The adjusting bolt 7025 is screwed into the side wall of the adjusting seat 7021. The end of the adjusting bolt 7025 abuts against the adjusting block 7024. The depth of the adjusting bolt 7025 can be used to fine adjust the position of the wire clamping block 701 and can also serve to fasten the wire clamping block 701. Together with the adjusting seat 7021 and the snap-fit ​​block 7023, the wire clamping block 701 is fixed securely.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
