Description

Technical Field

[0001] This utility model relates to the field of small electronic component processing, specifically to a pin header shearing and transistor pin bending device. Background Technology

[0002] Pin headers are connectors used in circuit boards, widely applied for PCB connections. Their structure includes a frame and pin bars, and multiple pin bars can be used together to meet different application needs. To improve production efficiency and expand the applicability of pin headers, they are typically manufactured as a large plate. This means the number of pin bars is not limited to a specific product requirement, but rather different for different models, with varying frame sizes and spacing between pin bars, making them universal pin headers of the same model. In practical applications, this large plate of pin headers needs to be cut to meet the required number of pin bars.

[0003] Currently, when producing small batches of needles with a specific number of needle bars, it is not possible to use large-scale equipment for large-batch cutting. Only small equipment can be used, but small equipment is expensive, and manual processing cannot guarantee cutting quality, while cutting efficiency is low.

[0004] Transistors are essential components in modern electronic devices, and their mounting structures on circuit boards are mainly through-hole and through-hole. For through-hole transistors, the transistor leads need to be bent at a 90-degree angle, requiring separate equipment for this bending process. For a small number of transistor bending operations, the cost of using advanced equipment is high, while manual bending requires specific tooling and suffers from poor quality and stability.

[0106] The transistor 14 adjustment seat is set on the placement platform 3 to position the distance between the tail of the transistor 14 to be bent and the extrusion surface 911 of the bending mechanism.

[0107] In this embodiment, the bending mechanism includes an extrusion block 91, which is fixedly connected to the lifting end of the vertical lifting mechanism 4.

[0108] The placement platform 3 is provided with a groove 31 directly opposite the adjustment seat of the transistor 14; the groove 31 is provided with several internal threaded holes;

[0109] The transistor 14 adjustment socket includes:

[0110] The placement base 101 is provided with a plurality of mounting holes that match the internal threaded holes in the groove 31; the placement base 101 is fixedly connected to the internal threaded holes in the groove 31 by screws passing through the mounting holes;

[0113] This embodiment also includes:

[0114] The protective cover 11 is U-shaped and is fastened to the outside of the bending mechanism and fixed to the upright plate 2.

[0119] The lifting cylinder 41 of the vertical lifting mechanism 4 extends, causing the extrusion block 91 to extrude the tube foot 141. The tube foot 141 is bent under the action of the support flange 103 and the extrusion block 91. At the same time, the worker presses the tube body 142 of the transistor with his fingers to prevent the transistor 14 from tilting up, ensuring that its tube foot 141 is bent smoothly.

[0120] After bending, the transistor is moved along the positioning protrusion 102 toward the discharge inclined plate 12, and the bent transistor 14 is discharged from the device.

[0121] When bending a large number of tubes, other plate-shaped tools can be used to press the tube body 142 of the tertiary tube to reduce the stability of the pressing and reduce the pressure on the worker's hands.
