Description

Technical Field

[0001] This utility model relates to the field of electronic component processing technology, and in particular to a pin forming device. Background Technology

[0002] In the manufacturing process of electronic devices, electronic components need to be assembled and soldered onto integrated circuit boards. In automated production, it is essential to ensure that parameters such as the pin height and pin position of the electronic components conform to the design of the integrated circuit board. Therefore, before assembling and soldering the electronic components onto the integrated circuit board, the pins of the electronic components need to be shaped, molded, and cut. In existing technologies, this shaping and molding process is performed manually. Utility Model Content

[0003] The purpose of this invention is to provide a pin forming device that can automatically form and cut the pins of electronic components to meet the design requirements of integrated circuit boards, and with high processing efficiency.

[0004] This invention provides a pin forming device for forming the pins of electronic components. The pin forming device includes a first support base, a second support base, and a forming slider. The first support base includes a forming support portion. A limiting member and a cutting block are fixedly disposed on the second support base; the limiting member has a sliding groove extending along a sliding direction; the cutting block is disposed between the second support base and the limiting member, and its surface facing the first support base has a cutting portion. The forming slider has a forming structure cooperating with the forming support portion at one end facing the first support base, and its end facing away from the first support base is disposed in the sliding groove. A first spring is disposed between the forming slider and the limiting member. When the second support base moves relative to the first support base along the sliding direction, the forming slider, under the action of the first spring, can compress the pin located at the forming support portion to form the pin of the electronic component through the forming structure. The cutting block, under the action of the second support base, can continue to move relative to the forming slider along the sliding direction to cut the pin of the electronic component. The pin forming device of this invention can automatically process the pins of electronic components to meet the design requirements of integrated circuit boards. It has a simple structure and only requires one device to form and cut the pins of electronic components in one workflow, resulting in high processing efficiency.

[0005] In another illustrative embodiment of the pin forming device of this utility model, a first limiting ridge protrudes from the plane of the forming support portion facing the forming slider, the extending direction of the first limiting ridge being perpendicular to the sliding direction and the extending direction of the electronic component pin; the forming structure of the forming slider includes a first limiting groove; wherein, when the second support seat moves relative to the first support seat along the sliding direction, the first limiting ridge can extend into the first limiting groove, and cooperate with the first limiting groove to bend the portion of the pin located at the position of the first limiting groove. The pin forming device of this utility model, by providing the first limiting ridge and the first limiting groove, can provide a bent portion on the first pin to precisely control the pin mounting height of the electronic component.

[0006] In another illustrative embodiment of the pin forming device of this utility model, a second limiting groove is further provided on the plane where the first limiting protrusion is located. The second limiting groove contains a first supporting surface and a second limiting inclined surface. The first supporting surface is perpendicular to the sliding direction, and the angle between the second limiting inclined surface and the first supporting surface is greater than 90 degrees, and the inclined surface faces the free end of the pin in the extension direction of the pin. The forming structure of the forming slider also includes a second limiting protrusion, which has a second supporting surface that mates with the first supporting surface and a first limiting inclined surface that mates with the second limiting inclined surface. By providing the second limiting groove and the second limiting protrusion, the pin forming device of this utility model can bend the second pin and accurately control the bending angle and the length of the bent segment of the second pin. This device allows the bent portion of the first pin and the bent segment of the intermediate pin (i.e., the second pin 13) of the electronic component to be formed simultaneously, improving production efficiency.

[0007] In another illustrative embodiment of the pin forming device of this utility model, in the extension direction of the pin, the edge formed by the intersection of the first limiting groove facing the free end of the pin and the second supporting surface and the second limiting inclined surface is at the same height. The pin forming device of this utility model enables the mounting height of the second pin to be consistent with the mounting height of the first pin.

[0008] In another illustrative embodiment of the pin forming apparatus of this utility model, in the extension direction of the pin, the end of the cutter portion facing the forming support portion is adjacent to the forming support portion.

[0009] In another illustrative embodiment of the pin forming device of this utility model, the limiting member is further provided with a limiting groove; the forming slider is provided with a slider limiting part, and the slider limiting part is at least partially disposed in the limiting groove; wherein, when the second support seat moves relative to the first support seat, the slider limiting part can slide in the limiting groove along the sliding direction.

[0010] In another illustrative embodiment of the pin forming apparatus of this utility model, when the forming slider leaves the forming support, the first spring can drive the forming slider so that the slider limiting part abuts against the surface of the limiting groove near the forming support, thereby preventing the forming slider from dislodging from the limiting member.

[0011] In another illustrative embodiment of the pin forming device of this utility model, the second support base further includes a support base receiving groove; the first support base further includes a support base limiting part; wherein, when the first support base and the second support base move relative to each other, the end of the support base limiting part is received in the support base receiving groove, and a second spring is also provided between the end of the support base limiting part and the support base receiving groove. After completing one forming and cutting process, the second support base of this utility model can quickly return to its initial position.

[0012] In another illustrative embodiment of the pin forming device of this utility model, the pin forming device further includes a mounting base and a mounting bracket. One end of the mounting bracket is fixedly connected to the mounting base, and a second adjusting rod is provided on the mounting bracket, extending along the extension direction of the pin. The end of the second support seat opposite to the first support seat has a mounting portion, which is screwed to the second adjusting rod. A first adjusting rod is also provided on the mounting portion, and the end of the first adjusting rod can lock the second support seat onto the mounting bracket. The forming device of this utility model facilitates adjustment of the height of the second support seat.

[0013] In another illustrative embodiment of the pin forming device of this utility model, a driving device includes a cylinder and a push rod disposed in the cylinder. One end of the push rod is disposed in the cylinder and the other end is connected to the mounting base. The push rod can push the mounting base to move along the sliding direction.

[0034] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0035] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0036] To keep the drawings concise, only the parts related to this utility model are shown schematically in each figure, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some figures, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0037] In this document, "one" can mean not only "only one" but also "more than one". In this document, "first", "second", etc., are used only to distinguish them from each other, not to indicate their importance or order. Electronic components with leads, especially those with three leads, such as LED dual-color indicator lights, are referred to in this document. The extension direction B of the leads, as referred to in this document, refers to the direction of the leads when the electronic component 10 is placed in the first support 30 position but before the leads have been processed. The mounting height of the leads, as referred to in this document, refers to the height of the leads above the integrated circuit board when the leads are placed on the integrated circuit board.

[0038] Figure 1 This is a schematic structural diagram illustrating the pin forming device of this utility model.

[0039] like Figure 1 As shown, the lead forming device includes a first support 30 and a second support 23, which are used to process the leads of electronic components. During processing, the first support 30 and the second support 23 cooperate to compress the leads of the electronic components, thereby shaping the leads into the required shape so that the mounting height, position between leads, bending angle, and length of the leads on the circuit board meet the design requirements of the integrated circuit board. During processing, an auxiliary device can be used to clamp the head of the electronic component and place it near the first support 30. Furthermore, the distance between the head of the electronic component and the first support 30 can be controlled by the auxiliary device to ensure the consistency of lead forming for the batch of electronic components. For example, the auxiliary device can be controlled to press the head of the electronic component against the first support 30, or the auxiliary device can be controlled to clamp the electronic component at a specific position and hover at a specific height on the first support 30, or other methods can be used.

[0040] The first support 30 of the pin forming device includes a forming support 31, on which a forming structure is provided.

[0041] A limiting member 26 and a cutting block 24 are fixedly mounted on the second support base 23. The cutting block 24 is disposed between the second support base 23 and the limiting member 26, and a cutting part 241 is provided on its surface facing the first support base 30. Specifically, the limiting member 26 and the second support base 23 can be fixed to two opposing surfaces of the cutting block 24 by welding; alternatively, screws can be used to sequentially pass through the limiting member 26, the cutting block 24, and the second support base 23 to fix them together.

[0042] like Figure 1 As shown, the limiting member 26 is generally U-shaped, with a sliding groove 261 on it. The sliding groove 261 extends along the sliding direction A. A forming slider 25 is disposed in the sliding groove 261, with one end of the forming slider 25 located inside the sliding groove 261 and the other end extending out of the sliding groove 261. The end of the forming slider 25 extending out of the sliding groove 261 faces the first support base 30, and is provided with a forming structure that cooperates with the forming structure of the forming support part 31. A first spring 27 is connected between the end of the forming slider 25 away from the first support base 30 and the limiting member 26.

[0043] When the second support 23 moves along the sliding direction A toward the first support 30, the forming slider 25 first contacts the pin located at the forming support 31 and presses it onto the first support 30. As the second support 23 continues to move toward the first support 30, the first spring 27 is compressed to provide a force along the sliding direction A to the forming slider 25. The force gradually increases as the second support 23 continues to move toward the first support 30, causing the forming slider 25 to work with the first support 30 to press the pin, thereby forming the pin of the electronic component 10 through the forming structure. The second support 23 moves further along the sliding direction A toward the first support 30, and the cutting block 24 continues to move relative to the forming slider 25 along the sliding direction A under the drive of the second support 23. Its cutting part 241 abuts against the pin and moves further to cut the pin. Therefore, this pin forming device can automatically process the pins of electronic components to meet the design requirements of integrated circuit boards. Moreover, its structure is simple, requiring only one device to perform pin forming and cutting in one workflow, resulting in high processing efficiency.

[0044] The lead forming device may further include a mounting base 21 and a mounting bracket 22. One end of the mounting bracket 22 is fixedly connected to the mounting base 21. A second adjusting rod 222, which is a screw, is provided on the mounting bracket 22 and extends along the extension direction B of the lead. The end of the second support 23 opposite to the first support 30 is provided with a mounting portion, which can extend into the mounting bracket 22 and be screwed to the second adjusting rod 222. A first adjusting rod 221, which is a screw, is also provided on the mounting portion, and its end can lock the second support 23 onto the mounting bracket 22. In use, first insert the mounting part of the second support 23 into the mounting frame 22. Then, install the second adjusting rod 222, passing one end through the mounting part and mounting it on the mounting frame 22. Since the mounting part and the second adjusting rod 222 are connected by a threaded connection, the height of the second support 23 can be adjusted by rotating the head of the second adjusting rod 222. Next, install the first adjusting rod 221 onto the mounting part of the second support 23 and tighten the first adjusting rod 221. The head of the first adjusting rod 221 and the main structure of the second support 23 can then clamp the mounting frame 22 together, thereby locking the second support 23 onto the mounting frame 22.

[0045] Figure 2 This is a schematic structural diagram illustrating part of the pin forming device of this utility model. Figure 3 This is a schematic structural diagram illustrating part of the pin forming device of this utility model. Figure 3 The image shows an electronic component 10 after molding and cutting. The electronic component 10 includes three pins, two of which, 11 and 12, are first pins, and the other pin, 13, is a second pin. Each of the two first pins has a bent portion, and the second pin, from its fixed end towards its free end, has a vertical section, a bent section, and a vertical section arranged sequentially.

[0046] like Figure 2 , Figure 3As shown, the molding support portion 31 of the first support base 30 has a first limiting ridge 311, 312 protruding from its plane facing the molding slider 25. The extending direction of the first limiting ridge 311, 312 is perpendicular to the sliding direction A and the extending direction B of the pin of the electronic component 10. The molding structure on the molding slider 25 includes first limiting grooves 251, 252 that match the first limiting ridges 311, 312. When the second support base 23 moves relative to the first support base 30 along the sliding direction A, the first limiting ridges 311, 312 can extend into the first limiting grooves 251, 252, and cooperate with the first limiting grooves 251, 252 to bend the portion of the pin located at the position of the first limiting grooves 251, 252. The pin portion at the upper and lower positions of the bent portion remains straight because it abuts against the plane of the molding support portion 31 and the molding slider 25. Therefore, by setting the first limiting protrusion and the first limiting groove, a curved part can be set on the first pin. The curved end determines the mounting height of the first pin of the electronic component on the circuit board. The pin forming device can ensure that the mounting height of the first pins 11 and 12 is uniform and meets the requirements.

[0047] like Figure 2 , Figure 3 As shown, a second limiting groove 313 is also provided on the plane where the first limiting protrusions 311 and 312 are located. The second limiting groove 313 contains a first supporting surface and a second limiting inclined surface 3131. The first supporting surface is perpendicular to the sliding direction A, and the angle between the second limiting inclined surface 3131 and the first supporting surface is greater than 90 degrees, and it faces the free end of the pin in the extending direction B of the pin. The forming structure of the forming slider 25 also includes a second limiting protrusion 253 that mates with the second limiting groove 313. The cross-section of the second limiting protrusion 253, perpendicular to the extending direction of the first limiting grooves 251 and 252, is a right-angled stepped shape. The second limiting protrusion 253 has a second supporting surface that mates with the first supporting surface and a first limiting inclined surface 2531 that mates with the second limiting inclined surface 3131. Therefore, by setting the second limiting groove and the second limiting protrusion, the second pin can be bent, so that the second pin forms a structure of "first straight section - bent section - second straight section" from the head of the electronic component. This pin forming device can ensure that the mounting height of the second pin 13 is uniform and meets the requirements. With this device, the bent part of the first pin and the bent section of the middle pin (i.e., the second pin 13) of the electronic component can be formed simultaneously, improving production efficiency.

[0048] Furthermore, to ensure that the mounting height of the first pins 11 and 12 is the same as that of the second pin 13, in the pin extension direction B, the edge formed by the intersection of the second supporting surface and the second limiting inclined surface 3131 can be positioned at the same height as the end of the first limiting grooves 251 and 252 facing the free end of the pin. Therefore, the bending point between the "bent section and the second straight section" on the second pin 13 is at the same height as the end of the bent portion of the first pins 11 and 12 near the free end of the pin. The pin forming device of this utility model enables the mounting height of the second pin to be the same as that of the first pin.

[0049] like Figure 1 , Figure 2 As shown, the limiting member 26 is also provided with a limiting groove 262, and the molding slider 25 is also provided with a slider limiting part 254. The slider limiting part 254 is at least partially disposed in the limiting groove 262. When the second support 23 moves relative to the first support 30, the slider limiting part 254 can slide in the limiting groove 262 along the sliding direction A. When the molding slider 25 leaves the molding support 31, the slider limiting part 254 can abut against the surface of the limiting groove 262 near the molding support 31 to prevent the molding slider 25 from falling out of the limiting member 26.

[0050] After completing a single forming and cutting process, a second spring can be installed between the first support 30 and the second support 23 to allow the second support 23 to quickly return to its initial position. For example... Figure 1 , Figure 2 As shown, a support seat limiting part 32 is provided on the first support seat 30, and a support seat receiving groove 231 is provided on the second support seat 23. When the first support seat 30 and the second support seat 23 move relative to each other, the end of the support seat limiting part 32 is received in the support seat receiving groove 231, and a second spring is also provided between it and the support seat receiving groove 231.

[0051] Figure 4a 4b is a structural schematic diagram illustrating the working principle of the pin forming device of this utility model.

[0052] Figure 4a The structural diagram shows that the pins have been extruded but not yet cut. Figure 4a In this state, the second support 23 is further driven to move towards the first support 30. The cutting block 24 moves towards the pin, with the end of its cutting blade 241 approaching the pin. Since the pin is confined between the first support 30 and the second support 23, as the cutting blade 241 moves further, as... Figure 4bAs shown, the cutter portion 241 cuts off the excess portion of the pin. The cutter portion 241 is positioned adjacent to the molding support portion 31 at its end in the pin's extension direction B.

[0053] To drive the second support 23 to move towards the first support 30, the pin forming device can also be equipped with a driving device. The driving device includes a cylinder and a push rod disposed within the cylinder. One end of the push rod is disposed inside the cylinder, and the other end is connected to the mounting base 21. The push rod can push the mounting base 21 to move along the sliding direction A, while the position of the first support 30 remains fixed. Alternatively, the position of the second support 23 can be fixed, and the push rod of the driving device can be connected to the first support 30 to push the first support 30 to move towards the second support 23 in the opposite direction of the sliding direction A. Two driving devices can also be provided, one driving the first support 30 and the other driving the second support 23, so that the first support 30 and the second support 23 move towards each other.

[0054] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other implementations that can be understood by those skilled in the art.
