Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a circuit board pin bending device. Background Technology

[0002] In modern electronics manufacturing, printed circuit boards (PCBs) serve as the core support and electrical connection carrier for electronic components. Their design and manufacturing processes directly affect the performance and reliability of the final product. PCBs typically have numerous pin-based electronic components soldered onto them, such as connectors, sockets, or specific discrete components. To meet specific spatial layout, mechanical fixation, or electrical connection requirements, the pins of these components often need to be bent after soldering, for example, bent at 90 degrees or a specific angle, to allow for mating or fixing with another circuit board, metal casing, or other structural components.

[0003] Currently, the traditional process commonly used in the industry for bending component pins on circuit boards is "separate boards first, then bend." Specifically, the entire panel after component mounting and reflow soldering is first divided into pre-designed individual boards (i.e., unit boards) using methods such as V-cut, milling, or stamping. Then, operators or dedicated single-board bending equipment bend the pins on these separated unit boards one by one or in batches. However, this traditional production process is no longer suitable for the demands of modern manufacturing for high efficiency, high consistency, and low cost. Utility Model Content

[0004] Therefore, it is necessary to provide a circuit board pin bending device to address the problem that traditional circuit board pin bending processes are no longer suitable for the requirements of modern manufacturing industries for high efficiency, high consistency, and low cost.

[0005] A circuit board pin bending device is used to bend the pins of components on a circuit board. The device includes a base plate, a stripping plate, and a bending plate. The stripping plate is installed between the base plate and the bending plate. The circuit board is installed between the stripping plate and the bending plate, with the pin face of the circuit board facing the bending plate. The bending plate has bending holes for mating with component pins. A slide rail is installed on the base plate, a crossbeam is installed on the slide rail, and rollers are installed on the crossbeam. The rollers are used to bend the component pins extending out of the bending holes. The unloading plate is connected to the first positioning pin, the bottom plate is provided with a guide groove that cooperates with the first positioning pin, the unloading plate is connected to a driving mechanism, the driving mechanism is used to drive the unloading plate to move so that the first positioning pin moves in the guide groove, the movement direction of the roller is parallel to the extension direction of the guide groove and the bending hole, the two ends of the guide groove are respectively provided with a first groove wall and a second groove wall, and the two ends of the bending hole are respectively provided with a first hole wall and a second hole wall. When the first positioning pin contacts the first groove wall, the component pin is located on one side of the first hole wall, so that the roller can press and bend the component pin along the movement direction from the second hole wall to the first hole wall; when the first positioning pin contacts the second groove wall, the component pin is located on one side of the second hole wall, so as to cooperate with the circuit board unloading.

[0006] When this circuit board pin bending device bends the pins of components on a circuit board, it first installs a stripper plate on a base plate, allowing the first locating pin to enter the guide groove. Then, the stripper plate is driven by a drive mechanism to move, causing the first locating pin to contact the first groove wall. Next, the circuit board is installed on the stripper plate, and a bending plate is installed so that the component pins extend out of the bending holes and are located on one side of the first hole wall. Then, the drive rollers move along the direction from the second hole wall to the first hole wall to press and bend the component pins, so that the bent part of the component pins is located outside the bending hole. Next, the drive mechanism drives the stripper plate to move, causing the first locating pin to contact the second groove wall, and the bent part of the component pins is located directly above the bending hole. Finally, the bending plate is removed, and the circuit board is unloaded. As can be seen, this circuit board pin bending device can achieve efficient bending of the entire circuit board. Through the modular structure design of the base plate, unloading plate, and bending plate, as well as the specially designed bending holes, the circuit board pin bending device can accommodate and position the entire circuit board that has not yet been separated. This allows all component pins to be bent at once and in batches, completely overturning the inefficient traditional "separate the boards first, then bend them one by one" mode, merging multiple operations into one, and improving production efficiency by orders of magnitude. Furthermore, through the precise cooperation between the first positioning pin and the guide groove, and the driving mechanism driving the unloading plate, precise positioning of two key stations is achieved: at the bending station, the first positioning pin contacts the first groove wall, ensuring that all component pins are precisely located on one side of the first hole wall before bending, providing a unified benchmark for the subsequent precise pressing and bending of the rollers, effectively ensuring the consistency of the bending angle and position of all component pins on the circuit board; at the unloading station, the first positioning pin contacts the second groove wall, ensuring that all component pins are precisely located on one side of the second hole wall after bending, with the bent part of the component pin located directly above the bending hole, thus effectively cooperating with the subsequent removal of the bending plate; this design cleverly utilizes the movement of the unloading plate, creating conditions for non-destructive unloading, and avoiding interference or collision between the bent component pins and the side wall of the bending hole during the unloading process, which could lead to deformation or damage. Furthermore, by setting the movement direction of the rollers parallel to the extension direction of the guide grooves and bending holes, the kinematic design of the entire device is highly unified. A single unidirectional movement of the rollers can complete the bending of an entire row or even an entire plate of pins. The action is simple and efficient, greatly simplifying the operation process, reducing the control complexity of the equipment, and improving reliability.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] This utility model discloses a circuit board pin bending device.

[0020] like Figures 1 to 8As shown, this circuit board pin bending device is used to bend the pins of components on a circuit board. The device includes a base plate 10, a stripping plate 20, and a bending plate 30. The stripping plate 20 is installed between the base plate 10 and the bending plate 30. The circuit board 40 is installed between the stripping plate 20 and the bending plate 30, with the pin face of the circuit board 40 facing the bending plate 30. The bending plate 30 has bending holes 31 for mating with component pins 41. A slide rail 50 is installed on the base plate 10, a crossbeam 60 is installed on the slide rail 50, and rollers 70 are installed on the crossbeam 60. The rollers 70 are used to bend the component pins 41 extending out of the bending holes 31.

[0021] The unloading plate 20 is connected to the first positioning pin 21. The base plate 10 is provided with a guide groove 11 that cooperates with the first positioning pin 21. The unloading plate 20 is connected to a drive mechanism 80. The drive mechanism 80 is used to drive the unloading plate 20 to move so that the first positioning pin 21 moves in the guide groove 11. The movement direction of the roller 70 is parallel to the extension direction of the guide groove 11 and the bending hole 31. The two ends of the guide groove 11 are respectively provided with a first groove wall 111 and a second groove wall 112. The two ends of the bending hole 31 are respectively provided with a first hole wall 311 and a second hole wall 312. When the first positioning pin 21 contacts the first groove wall 111, the component pin is located on one side of the first hole wall 311 so that the roller 70 can press and bend the component pin 41 along the movement direction from the second hole wall 312 to the first hole wall 311. When the first positioning pin 21 contacts the second groove wall 112, the component pin 41 is located on one side of the second hole wall 312 so as to cooperate with the unloading of the circuit board 40.

[0022] When this circuit board pin bending device bends the pins of components on a circuit board, it first installs a stripper plate on a base plate, allowing the first locating pin to enter the guide groove. Then, the stripper plate is driven by a drive mechanism to move, causing the first locating pin to contact the first groove wall. Next, the circuit board is installed on the stripper plate, and a bending plate is installed so that the component pins extend out of the bending holes and are located on one side of the first hole wall. Then, the drive rollers move along the direction from the second hole wall to the first hole wall to press and bend the component pins, so that the bent part of the component pins is located outside the bending hole. Next, the drive mechanism drives the stripper plate to move, causing the first locating pin to contact the second groove wall, and the bent part of the component pins is located directly above the bending hole. Finally, the bending plate is removed, and the circuit board is unloaded. As can be seen, this circuit board pin bending device can achieve efficient bending of the entire circuit board. Through the modular structure design of the base plate, unloading plate, and bending plate, as well as the specially designed bending holes, the circuit board pin bending device can accommodate and position the entire circuit board that has not yet been separated. This allows all component pins to be bent at once and in batches, completely overturning the inefficient traditional "separate the boards first, then bend them one by one" mode, merging multiple operations into one, and improving production efficiency by orders of magnitude. Furthermore, through the precise cooperation between the first positioning pin and the guide groove, and the driving mechanism driving the unloading plate, precise positioning of two key stations is achieved: at the bending station, the first positioning pin contacts the first groove wall, ensuring that all component pins are precisely located on one side of the first hole wall before bending, providing a unified benchmark for the subsequent precise pressing and bending of the rollers, effectively ensuring the consistency of the bending angle and position of all component pins on the circuit board; at the unloading station, the first positioning pin contacts the second groove wall, ensuring that all component pins are precisely located on one side of the second hole wall after bending, with the bent part of the component pin located directly above the bending hole, thus effectively cooperating with the subsequent removal of the bending plate; this design cleverly utilizes the movement of the unloading plate, creating conditions for non-destructive unloading, and avoiding interference or collision between the bent component pins and the side wall of the bending hole during the unloading process, which could lead to deformation or damage. Furthermore, by setting the movement direction of the rollers parallel to the extension direction of the guide grooves and bending holes, the kinematic design of the entire device is highly unified. A single unidirectional movement of the rollers can complete the bending of an entire row or even an entire plate of pins. The action is simple and efficient, greatly simplifying the operation process, reducing the control complexity of the equipment, and improving reliability.

[0023] The crossbeam 60 is equipped with a handle 61, and the handle 61 and roller 70 are respectively installed on the upper and lower sides of the crossbeam 60. By installing the handle 61 on the crossbeam 60, an ergonomically designed point of force is provided for the operator. The roller 70 can be driven to complete the bending operation by manually pulling the handle 61, reducing the intensity of operation and improving safety and convenience. The separate placement of the handle 61 and roller 70 on both sides makes the circuit board pin bending device more compact.

[0024] The bending plate 30 is provided with a groove 32 that mates with the unloading plate 20. By providing the groove 32 on the bending plate 30, it is ensured that the unloading plate 20 and the bending plate 30 can form a flat and coplanar bearing surface after installation. This prevents the circuit board 40 from being stressed or warped due to unevenness during installation and pressing, ensuring that the component pins are subjected to uniform force during bending, and further ensuring the stability of the bending quality.

[0025] The slide rail 50 includes a first slide rail 51 and a second slide rail 52, with the unloading plate 20 and bending plate 30 installed between the first slide rail 51 and the second slide rail 52. By employing the double-rail structure of the first slide rail 51 and the second slide rail 52, symmetrical and stable guiding support is provided for the movement of the crossbeam 60 and the roller 70, effectively preventing the crossbeam 60 from skewing or jamming during movement. This ensures that the bending force applied by the roller 70 to the entire row of component pins is uniform and consistent, thereby guaranteeing the accuracy of the bending angle of all component pins.

[0026] The drive mechanism 80 includes a drive block 81, a connecting rod 82, a drive wheel 83, and a handle 84. The unloading plate 20 is connected to the drive block 81, the drive block 81 is connected to the connecting rod 82, the connecting rod 82 is connected to the drive wheel 83, and the drive wheel 83 is connected to the handle 84. The drive block 81, connecting rod 82, drive wheel 83, and handle 84 constitute a linkage mechanism, giving the drive mechanism 80 self-locking and force amplification capabilities. By easily pushing the handle 84, the operator can amplify the force through the drive mechanism 80 and precisely control the movement and positioning of the unloading plate 20. The drive mechanism 80 has a simple and reliable structure, low manufacturing cost, and can provide a sufficiently large locking force to ensure that there is no relative displacement between the unloading plate 20 and the bending plate 30 during the bending process.

[0027] The circuit board pin bending device also includes a worktable, with a base plate 10 mounted on the worktable and a pad 90 installed between the base plate 10 and the worktable. By setting the pad 90, the height of the entire circuit board pin bending device can be adjusted to adapt to different working environments or the height of operators, improving the adaptability and ergonomics of the device. At the same time, the pad 90 also reduces the impact of external vibrations on bending accuracy.

[0028] The pad 90 includes a first pad 91 and a second pad 92, which are symmetrically arranged on both sides of the bottom of the base plate 10. By setting the first pad 91 and the second pad 92 respectively, the base plate 10 is ensured to be subjected to balanced force, avoiding deformation caused by uneven force on one side over a long period of time, extending the service life of the circuit board pin bending device, and maintaining the accuracy for long-term use.

[0029] The circuit board 40 is connected to the second positioning pin 42, and the unloading plate 20 is provided with a first positioning hole 22 that cooperates with the second positioning pin 42. Through the cooperation between the second positioning pin 42 and the first positioning hole 22, the circuit board 40 is accurately positioned on the unloading plate 20, preventing the circuit board 40 from sliding or misaligning during processing. This ensures the relative positional accuracy of the component pins 41 and the bending holes 31 from the source, thus ensuring the final bending quality.

[0030] The bending plate 30 is connected to the third positioning pin 33, and the base plate 10 is provided with a second positioning hole 12 that cooperates with the third positioning pin 33. Through the cooperation between the third positioning pin 33 and the second positioning hole 12, the bending plate 30 is accurately positioned on the base plate 10, ensuring that the relative position between the bending hole 31 and the movement trajectory of the roller 70 remains unchanged, thereby ensuring the consistency of bending accuracy in different batches of production.

[0031] This utility model also discloses a working method of the above-mentioned circuit board pin bending device, including steps S1 to S6, as described below: Step S1: Install the unloading plate on the base plate so that the first positioning pin enters the guide groove.

[0032] This step completed the initial assembly of the core functional modules and established a reference positioning system for the entire circuit board pin bending device, laying the foundation for the precise movement of the subsequent unloading plate.

[0033] Step S2: Drive the unloading plate to move through the drive mechanism, so that the first positioning pin contacts the first groove wall.

[0034] This step completes the precise positioning before bending. By locking the stripper plate at the bending station, it ensures that all component pins are in a uniform position before bending, thus providing the conditions for batch bending of component pins.

[0035] Step S3: Install the circuit board onto the unloading plate and install the bending plate so that the component pins extend out of the bending hole and are located on one side of the first hole wall.

[0036] This step, by installing the circuit board and bending plate, provides accurate working space and force support points for the pressing and bending of the rollers.

[0037] Step S4: Drive the roller to press and bend the component pin along the movement direction from the second hole wall to the first hole wall, so that the bent part of the component pin is located outside the bending hole.

[0038] This step involves continuous rolling and pressing with rollers, applying force evenly and avoiding impact, resulting in high-quality and consistent bending of component pins.

[0039] Step S5: Drive the unloading plate to move through the drive mechanism, so that the first positioning pin contacts the second groove wall, and the bent part of the component pin is located directly above the bending hole.

[0040] This step is crucial for achieving non-destructive unloading. The entire unloading board carrying the circuit board is moved to the unloading station by the drive mechanism, so that the bent component pins are completely misaligned with the sidewalls of the bending holes in the vertical direction, eliminating the possibility of physical interference.

[0041] Step S6: After removing the bending plate, cut the circuit board into pieces.

[0042] Since the aforementioned steps have eliminated interference between component pins and bending holes, the bent board can be easily and directly removed without scratching or bumping the bent component pins. The circuit board can then be safely removed, perfectly solving the industry pain point of difficulty in removing the bent circuit board and ensuring the final quality of the product.

[0043] As can be seen, the working method of this circuit board pin bending device can achieve efficient bending of the entire circuit board. Through the modular structure design of the base plate, unloading plate, and bending plate, as well as the specially set bending holes, the circuit board pin bending device can accommodate and position the entire circuit board that has not yet been separated. This allows all component pins to be bent at once and in batches, completely overturning the inefficient traditional "separate the boards first, then bend them one by one" mode, merging multiple operations into one, and improving production efficiency by orders of magnitude.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
