[0001] This utility model relates to the technical field of electronic component lead bending equipment, and specifically to a lead bending processing device. Background Technology

[0002] With the rapid development of the automation industry, its applications are particularly prominent in the electronics and electrical industries. These industries use a large number of electronic components, and to meet the requirements of connecting with other parts or circuits, it is often necessary to bend the leads of workpieces into the required shapes. In existing technical solutions, most bending of workpiece leads is done manually using jigs and other processing devices. Some commercially available processing devices have complex transmission structures, resulting in high manufacturing and maintenance costs; their transmission structure also has low stability, easily leading to shaking and jamming during operation, affecting the normal operation and lifespan of the equipment. Therefore, there is a need to design a processing device that is simple in structure, stable in operation, and highly reliable. Utility Model Content

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model provides a pin bending processing device, including a work platform. The work platform is equipped with a transmission rod, a guide, a cutting tool, a linkage mechanism, and a handle. The guide guide moves the transmission rod along its axis. One end of the linkage mechanism is hinged to the work platform, and the hinge point remains constant relative to the work platform; the other end is hinged to the transmission rod. The handle is connected to the linkage mechanism, and a force can be applied to the handle to drive the transmission rod to reciprocate along its axis via the linkage mechanism. The cutting tool is connected to the transmission rod so that it can bend the pin of the workpiece as the transmission rod moves.

[0006] Optionally, the linkage mechanism includes a main link and a secondary link. One end of the main link is hinged to the working platform, and the position of the hinge point remains unchanged relative to the working platform. The other end is hinged to one end of the secondary link, and the other end of the secondary link is hinged to the end of the transmission rod. The handle is perpendicular to and fixedly connected to the main link. The linkage mechanism is configured such that when the handle is in a horizontal state, the hinge points of the main link and the working platform, the main link and the secondary link, and the secondary link and the transmission rod are located on the same vertical line, and the tool can perform a bending action on the workpiece pin.

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figure 1-3 This embodiment provides a pin bending processing device, including a work platform 1. The work platform 1 includes a mounting frame 2, on which a transmission rod 3, a guide 4, a linkage mechanism 6, a handle 7, and a cutting tool 5 are disposed. The guide 4 guides the transmission rod 3 to move along its axis. One end of the linkage mechanism 6 is hinged to the work platform 1, and the position of this hinge point remains unchanged relative to the work platform 1; the other end is hinged to the transmission rod 3. The handle 7 is connected to the linkage mechanism 6, and a force can be applied to the handle 7 to drive the transmission rod 3 to reciprocate along its axis via the linkage mechanism 6. The cutting tool 5 is connected to the transmission rod 3 so that the cutting tool 5 can bend the pin of the workpiece as the transmission rod 3 moves. In this embodiment, the transmission rod 3 is arranged vertically, and its orientation is described in this state.

[0023] Specifically, the linkage mechanism 6 includes a main link 61 and a secondary link 62. One end of the main link 61 is hinged to the mounting bracket 2, and this hinge point remains constant relative to the working platform 1. The other end is hinged to one end of the secondary link 62, and the other end of the secondary link 62 is hinged to the end of the transmission rod 3. One end of the handle 7 is fixedly connected to the end of the main link 61 near the secondary link 62. In this embodiment, the handle 7 is integrally connected to the main link 61 and is L-shaped. Applying force to the handle 7 causes the main link 61 to swing, which in turn drives the transmission rod 3 via the secondary link 62, thus achieving power transmission and motion transformation. The linkage mechanism 6 is configured such that when the handle 7 is in a horizontal state, the hinge points of the main link 61, the secondary link 62, and the transmission rod 3 are located on the same vertical line, and the cutter 5 can complete the bending action on the workpiece pin; that is, at this time, the force applied vertically downward on the handle 7 is transmitted to the secondary link 62 and the transmission rod 3. Since both the secondary link 62 and the transmission rod 3 are in a vertical state, the force is almost not decomposed, which can further improve the transmission efficiency.

[0024] In addition, wear-resistant bushings are installed at each hinge point of the linkage mechanism 6 to reduce friction and wear, and improve transmission efficiency and service life. By designing the linkage mechanism 6 and the handle 7, the up and down movement of the transmission rod 3 is realized. The transmission structure design is simple, the transmission efficiency is high, the number of components is small, the manufacturing difficulty and cost are reduced, and it is also convenient for later maintenance and repair.

[0025] The work platform 1 is equipped with a guide plate 8 and a first guide rod 9. The guide plate 8 is fixedly connected to the lower end of the transmission rod 3, and the plane of the guide plate 8 is perpendicular to the axis of the transmission rod 3. The first guide rod 9 is parallel to the axis of the transmission rod 3, and the lower end of the first guide rod 9 is fixed to the work platform 1, while the other end slidably passes through the guide plate 8. One side of the guide plate 8 is fixedly connected to the tool 5. A guide sleeve 10 is configured on the guide plate 8 corresponding to the first guide rod 9, and the first guide rod 9 slidably passes through the guide sleeve 10. The arrangement of the guide plate 8 and the first guide rod 9 makes the tool 5 move more smoothly during the process, thereby improving the machining quality of the workpiece. The number of first guide rods 9 is set according to the actual situation.

[0026] like Figure 3 To facilitate bending of the workpiece leads, a limiting seat 11 is fixedly installed on the work platform 1. The limiting seat 11 has a limiting groove 12 for placing the workpiece. Driven by the transmission rod 3, the tool 5 can approach the limiting seat 11 and bend the leads on the workpiece. In other embodiments, multiple limiting grooves 12 can be arranged side by side, so that the tool 5 can bend the leads of multiple workpieces in one operation.

[0027] The guide plate 8 is equipped with a return spring 13 and a spring seat 14. A second guide rod 15 is fixedly mounted on the spring seat 14. The axis of the second guide rod 15 is parallel to the axis of the transmission rod 3. The second guide rod 15 slidably passes through the guide plate 8. Similarly, the guide plate 8 is equipped with a guide sleeve 10 for the second guide rod 15 to slide through. One end of the return spring 13 is connected to the spring seat 14, and the other end is connected to the guide plate 8, so that the spring seat 14 can move closer to or further away from the limiting seat 11 as the guide plate 8 moves. When the guide plate 8 descends, the lower end face of the spring seat 14 can descend with the guide plate 8 and press against the limiting groove 12 to limit the workpiece displacement and ensure that the tool 5 performs bending processing on the accurate position of the workpiece pin. After the return spring 13 is released, it can drive the guide plate 8 away from the limiting seat 11, thereby allowing the tool 5 to return to its initial state.

[0028] The cutting tool 5 is detachably mounted on one side of the guide plate 8. Specifically, the cutting tool 5 has a first mounting hole 16, which is a strip-shaped hole arranged vertically along its length. The cutting tool 5 is locked to one side of the guide plate 8 by bolts passing through the first mounting hole 16, so that the height of the cutting tool 5 can be adjusted vertically. In this way, it is convenient to replace or adjust the height of the cutting tool 5 to adapt to different working conditions.

[0029] In addition, the mounting frame 2 is also equipped with a mounting base 17, which is height-adjustable relative to the work platform 1. The linkage mechanism 6 and the guide part 4 are both arranged and connected to the mounting base 17, wherein the guide part 4 is a sleeve structure and is integrally connected to the mounting base 17. Specifically, the mounting frame 2 is provided with a second mounting hole 18, which is a strip-shaped hole with its length arranged vertically. The mounting base 17 is locked and fixed to the mounting frame 2 by bolts passing through the second mounting hole 18, so that the mounting base 17 can be height-adjusted relative to the work platform 1.

[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
