[0036] In the process of manufacturing electronic devices, it is often necessary to bend the pins of the electronic devices to meet the assembly requirements. However, the existing pin bending devices have obvious limitations: the adaptability of the devices to electronic devices is poor, and it is difficult to adapt to electronic devices of different sizes and shapes.

[0037] The main object of the present invention is to propose a pin bending device, aiming to at least solve the technical problem in the related art that the adaptability to electronic devices is poor and it is difficult to adapt to electronic devices of different sizes and shapes.

[0038] Please refer to Figures 1 to 3, in an embodiment of the present invention, the pin bending device 100 is used to bend the pins of the electronic device 200. The pin bending device 100 includes a base 1, a pin support structure 2, a limiting structure 3, and a bending structure 5. The pin support structure 2 includes a support member 21 disposed on one side of the base 1 in the first horizontal direction. The upper end of the support member 21 protrudes from the base 1 and is used to support the pins of the electronic device 200. The limiting structure 3 includes a limiting member 31 and a first driving member 32 disposed on the upper side of the base 1. A limiting channel 4 extending in the second horizontal direction is defined between the limiting member 31 and the support member 21. The limiting channel 4 is formed with a loading position 41 and a bending position 42 spaced apart in the first direction. The limiting channel 4 is used to limit the main body of the electronic device 200. The first driving member 32 is used to drive the limiting member 31 to move along the first horizontal direction to adjust the size of the limiting channel 4 in the second horizontal direction. The bending structure 5 is disposed corresponding to the bending position 42. The bending structure 5 includes a pressing head 51 and a pressing driving member 52. The pressing head 51 can move in the vertical direction and can be attached to the side of the support member 21 away from the limiting member 31 within its moving stroke to bend the pins. The pressing driving member 52 is used to drive the pressing head 51 to move.

[0039] In the technical solution of the present invention, the precise positioning of the main body of the electronic device 200 is realized through the limiting structure 3 that can adjust the size of the limiting channel 4, and the adaptable bending of pins with different sizes is realized in cooperation with the movable bending structure 5, solving the technical problem of poor adaptability of existing devices.

[0040] Specifically, the limiting member 31 moves horizontally under the driving action to make the channel width adapt to the size of the device main body, and the electronic device 200 can be moved along the limiting channel 4 from the initial loading position 41 to the bending position 42. The protruding upper end of the support member 21 forms a stable pin support surface, keeping the pin root fixed during the bending process. When the device reaches the bending position 42, the pressing head 51 presses vertically under the driving action, and the bending surface at the end of its movement path is in close contact with the outside of the support member 21, bending the pin part extending above the support member 21 downward along the contact surface. Since the width of the limiting channel 4 has been adjusted according to the device size, the device main body will not have a horizontal displacement during the bending process, ensuring the accuracy of the bending angle. After the bending is completed, the pressing head 51 resets, and the limiting member 31 can be repositioned according to the size requirements of the next workpiece.

[0041] Of course, in order to further improve the stability during the bending process, a pressing mechanism can be provided at the bending position 42, that is, when the electronic device 200 reaches the bending position 42, the electronic device 200 is pressed and fixed through the pressing mechanism to keep it fixed.

[0042] The present application further proposes a conveying member 6 provided on the base 1, and the conveying member 6 is used to convey the electronic device 200 from the loading position 41 to the bending position 42.

[0043] Among them, the conveying member 6 refers to a mechanical structure capable of conveying materials along a preset path, and specifically, a conveyor belt, a roller group or a slide rail mechanism can be used to implement it. In the technical solution, the conveying member 6 is arranged on the surface of the base 1 and forms a spatial fit with the limiting channel 4, and the electronic device 200 is transferred between workstations through continuous or intermittent movement. This component replaces manual handling through automated mechanical transmission to ensure the positioning accuracy of the electronic device 200 in the bending process.

[0044] Specifically, the conveying member 6 is integrated on the surface of the base 1 and extends through the working area of the limiting channel 4. When the electronic device 200 is placed at the loading position 41, the conveying member 6 starts and drives the main body of the electronic device 200 to move along the limiting channel 4. During the movement, the support members 21 and the limiting members 31 on both sides of the limiting channel 4 jointly restrict the displacement of the electronic device 200 to ensure the linearity of the movement trajectory. Through the above technical solution, the present application realizes the automatic transfer of workstations of the electronic device 200 in the bending process, effectively shortening the single-piece processing cycle.

[0045] The present application further proposes that the pin bending device 100 includes a conveyor belt provided on the upper side of the base 1, and the conveyor belt is located in the limiting channel 4.

[0046] Specifically, after the electronic device 200 is placed on the surface of the conveyor belt, it moves along the second horizontal direction with the conveyor belt. At the same time, the limiting channel 4 forms constraints on both sides of the main body of the electronic device 200 to prevent it from shifting or tilting during the conveying process. The conveyor belt is completely accommodated in the limiting channel 4, so that the movement trajectory of the electronic device 200 is consistent with the extending direction of the limiting channel 4. When the width of the limiting channel 4 is adjusted by the limiting member 31, the conveyor belt can still maintain the conveying stability of the electronic device 200 in the adjusted channel without additional adjustment of the conveying mechanism.

[0047] Compared with the prior art, traditional devices usually adopt an independently arranged conveying device and a limiting structure 3, resulting in a complex equipment layout and difficulty in synchronously adjusting the conveying and limiting functions. In this solution, by embedding the conveyor belt in the limiting channel 4, the conveying and limiting functions are integrated in space, which not only simplifies the mechanical structure, but also directly accommodates electronic devices 200 of different sizes through the adjustability of the limiting channel 4.

[0048] The present application further proposes that the size of the conveyor belt in the first horizontal direction is smaller than that of the limiting channel 4.

[0049] Among them, the conveyor belt refers to a transmission component arranged on the upper side of the base 1 for carrying and conveying the electronic device 200. Specifically, it can be implemented by an annular belt structure made of rubber or metal, and anti-slip textures can be provided on its surface to increase friction. The limiting channel 4 refers to the space structure formed between the limiting member 31 and the supporting member 21. Specifically, the width of the channel can be changed by adjusting the horizontal displacement of the limiting member 31, and its size is limited to accommodate the main body of the electronic device 200 and allow it to move along the second horizontal direction.

[0050] Specifically, the width of the conveyor belt is designed to be smaller than the maximum adjustment range of the limiting channel 4 in the first horizontal direction, so that when the limiting member 31 is driven to move in the first horizontal direction, there are always gaps between both sides of the conveyor belt and the inner wall of the limiting channel 4. This gap provides a moving space for the movement of the limiting member 31 and prevents structural interference between the conveyor belt and the limiting member 31. Under this condition, the width adjustment process of the limiting channel 4 is not restricted by the size of the conveyor belt, so as to adapt to the main bodies of electronic devices 200 of different sizes, and at the same time, the conveyor belt can still maintain a stable conveying function within the limiting channel 4.

[0051] Compared with the prior art, the sizes of the conveyor belt and the limiting channel 4 in traditional equipment are usually fixedly matched, resulting in a limited adjustment range of the limiting channel 4 and being unable to be compatible with electronic devices 200 of different specifications. However, in this solution, by restricting the dimensional relationship between the conveyor belt and the limiting channel 4, not only the conveying function is retained, but also the adjustment freedom of the limiting channel 4 is significantly improved.

[0052] Through the above technical solution, the present application realizes the collaborative work of the conveying system and the limiting structure 3. On the premise of ensuring that the main body of the electronic device 200 is stably supported, the limiting channel 4 is allowed to be flexibly adjusted according to the device size, thereby expanding the adaptability of the equipment to electronic devices 200 of different specifications, and at the same time avoiding component wear or positioning deviation caused by structural interference.

[0053] The present application further proposes a pin bending device 100, in which the downward pressing driving member 52 can be movably arranged along the first horizontal direction, and the supporting member 21 includes a first supporting portion 211 and a second supporting portion 212. The first supporting portion 211 is arranged in contact with the side of the base 1 and defines the limiting channel 4 together with the limiting member 31, and the upper side of the first supporting portion 211 is used to support the pins. The second supporting portion 212 is arranged on the side of the first supporting portion 211 away from the limiting member 31, and can be in contact with the pressing head 51 within its moving stroke, and the second supporting portion 212 can be movably arranged along the first horizontal direction to adjust the supporting position.

[0054] Among them, the downward pressing driving member 52 being movably arranged along the first horizontal direction means that the power component driving the downward pressing head 51 can move in the horizontal direction. Specifically, it can be realized by a linear slide rail cooperating with a servo motor, and the position of the downward pressing head 51 is adjusted to match the position of the supporting portion. The first supporting portion 211 refers to a rigid supporting structure fixed to the side of the base 1, and can be specifically made of a metal block or high-strength plastic, and is used to provide stable support for the main body of the electronic device 200 on the fixed side of the limiting channel 4. The second supporting portion 212 refers to a movable supporting structure located outside the first supporting portion 211, and can be specifically realized by a combination of a slider and a guide rail, and the position of the supporting point for the pin is changed through horizontal displacement.

[0055] Specifically, when there are differences in the pin positions or dimensions of the electronic device 200, the second supporting portion 212 adjusts the position of the supporting point for the pins through horizontal movement, and the downward pressing driving member 52 moves horizontally synchronously therewith, so that the downward pressing head 51 always aligns with the preset contact surface of the second supporting portion 212. When the downward pressing head 51 fits with the side of the second supporting portion 212 away from the limiting member 31 during the vertical stroke, the vertical pressure is converted into a bending force for the pins. The limiting channel 4 formed by the first supporting portion 211 and the limiting member 31 restricts the main body of the electronic device 200 to prevent it from shifting during the bending process, and the adjustability of the second supporting portion 212 enables the same device to adapt to electronic devices 200 with different pin pitches or protrusion lengths.

[0056] Compared with the prior art, the traditional pin bending device 100 adopts a fixed supporting structure and cannot adapt to devices with different pin layouts, resulting in deviations in the bending position 42 or the device being unable to be installed. This solution solves the adaptability problem caused by pin size differences by introducing a linkage structure of the horizontally movable second supporting portion 212 and the downward pressing driving member 52, enabling the supporting position and the downward pressing action to be dynamically adjusted according to the pin position.

[0057] Through the above technical solution, the present application realizes the dynamic adjustment of the supporting position of the pins of the electronic device 200, ensures that pins of different sizes or positions obtain precise support during the bending process, and avoids bending angle deviations or device damage caused by fixed supporting positions. At the same time, the movable downward pressing driving member 52 and the adjustable supporting portion form a coordinated cooperation, enabling the device to be compatible with various specifications of electronic devices 200 and expanding the applicable range of the device.

[0058] The present application further proposes that the supporting member 21 further includes a second driving portion 213 drivingly connected to the second supporting portion 212, and the second driving portion 213 is used to drive the second supporting portion 212 to move along the first horizontal direction.

[0059] Among them, the second driving part 213 refers to a power output device capable of generating linear motion. Specifically, a servo motor cooperating with a lead screw, a cylinder or a hydraulic cylinder can be adopted, and the driving force is transmitted through the rigid connection between the output end and the second supporting part 212.

[0060] Specifically, when the pin length or bending position 42 of the electronic device 200 changes, the second driving part 213 receives an external control signal and starts to operate, driving the second supporting part 212 to translate along the first horizontal direction. The displacement of the second supporting part 212 can be preset according to the specific specifications of the electronic device 200 or adjusted in real time through a sensor, ensuring that the pins are always accurately supported within a predetermined area during the bending process. This adjustment process does not require replacing parts and can be completed through the direct linkage of the driving mechanism and the supporting structure, enabling the same device to be compatible with various types of electronic devices 200.

[0061] Through the above technical solution, the present application can quickly adjust the position of the second supporting part 212 without replacing the hardware structure, ensuring that the pins of electronic devices 200 with different specifications are stably supported during the bending process, effectively improving the versatility of the device and the bending processing accuracy.

[0062] The present application further proposes that the pin supporting structure 2 further includes a connecting member 7 connecting the second supporting part 212 and the downward pressing driving member 52. The connecting member 7 is used to drive the downward pressing driving member 52 to move along the first horizontal direction when the second supporting part 212 moves along the first horizontal direction.

[0063] Among them, the connecting member 7 refers to a mechanical component that realizes the rigid linkage between the second supporting part 212 and the downward pressing driving member 52. Specifically, a combination structure of a sliding guide rail and a connecting rod can be adopted, and the displacement amounts of the two are transmitted through fixed connection points to ensure that the relative positions remain constant during horizontal movement.

[0064] Specifically, when the second supporting part 212 moves along the first horizontal direction according to the size of the electronic device 200, the connecting member 7 synchronously transmits the displacement amount to the downward pressing driving member 52, so that the downward pressing driving member 52 and the second supporting part 212 generate an equal-distance displacement. This linkage mechanism enables the distance between the downward pressing head 51 and the outside of the second supporting part 212 to always remain a preset value. No matter what adjustment position the supporting part is in, when the downward pressing head 51 presses down, it can accurately abut against the preset bending surface of the second supporting part 212, eliminating the deviation of the downward pressing path caused by the movement of the supporting part.

[0065] Compared with the prior art, in traditional equipment, after the supporting part is adjusted, the position of the downward pressing mechanism needs to be manually recalibrated, while in this solution, automatic positioning is achieved through mechanical linkage, avoiding the positioning error caused by manual intervention. In the prior art, there is a problem of cumulative tolerance when independently adjusting the supporting part and the downward pressing mechanism. In this solution, the relative displacement deviation between the two parts is eliminated through the rigid connecting member 7.

[0066] With the above technical solution, the present application ensures that when the pin support position is adjusted, the bending actuator automatically follows the positioning, maintaining the spatial correspondence between the lower pressing head 51 and the bending reference plane on the outer side of the support part, solving the problem of misalignment of the bending position 42 caused by the movement of the support part, and improving the bending consistency of electronic devices 200 of different sizes. Further, the linkage structure simplifies the equipment adjustment process, avoids repeated positioning operations, and improves the processing efficiency and automation level.

[0067] The present application further proposes a lifting mechanism 8 drivingly connected to the support 21. The lifting mechanism 8 is used to drive the support 21 to move in the up and down directions, and the connecting member 7 can be telescopically arranged in the up and down directions.

[0068] Among them, the lifting mechanism 8 refers to a driving device capable of adjusting the position in the vertical direction. Specifically, an electric push rod, a hydraulic cylinder or a lead screw nut mechanism can be used to achieve it. Its function is to adapt to the main body of the electronic device 200 with different thicknesses by adjusting the height position of the support 21.

[0069] Among them, the connecting member 7 that can be telescopically arranged in the up and down directions refers to a transmission component with the ability to adjust the longitudinal length. Specifically, a sliding nested sleeve structure or a guide rail slider combination structure can be used to achieve it. Its function is to automatically adjust its own length during the lifting process of the support 21 and maintain the power transmission relationship between the second support part 212 and the lower pressing driving part 52.

[0070] Specifically, when processing electronic devices 200 with different thicknesses, the lifting mechanism 8 drives the support 21 to move up or down to make the pin support plane match the actual thickness of the main body of the electronic device 200. At this time, the connecting member 7 compensates for the height difference caused by the position change of the support 21 through up and down telescopic movements, ensuring that the lower pressing driving part 52 and the second support part 212 always maintain an effective connection. For example, when the support 21 rises, the first connection part of the connecting member 7 slides upward along the second connection part to avoid equipment jamming caused by rigid connection; when the support 21 descends, the connecting member 7 automatically contracts by its own weight or a return spring. This dynamic cooperation enables the downward pressing stroke of the bending structure 5 to always be precisely corresponding to the support position of the pins, eliminating the bending angle deviation caused by height misalignment.

[0071] The present application further proposes a structure of the connecting member 7, including a first connection part and a second connection part. The first connection part is fixedly connected to the lower pressing driving part 52 and is slidably arranged up and down with the second connection part, and the second connection part is fixedly connected to the second support part 212.

[0072] Among them, the first connecting part refers to the component rigidly connected to the downward pressing driving part 52, which can be specifically realized by combining a rectangular metal block with bolt fastening, and is used to transmit the driving force of the downward pressing driving part 52 to the bending structure 5. The second connecting part refers to the component fixedly connected to the second supporting part 212, which can be specifically realized by a sliding seat structure with a guiding groove, and is used to drive the downward pressing driving part 52 to displace synchronously when the supporting part 21 moves horizontally. The up-and-down sliding setting means that the two connecting components form a telescopic sliding fit relationship in the vertical direction, which can be specifically realized by a dovetail groove guide rail or a linear bearing structure, so that the connecting piece 7 can freely expand and contract when the supporting part 21 moves up and down.

[0073] Specifically, when the lifting mechanism 8 drives the supporting part 21 to move up and down, the second connecting part rises and falls synchronously with the supporting part 21. The sliding fit between the first connecting part and the second connecting part allows relative displacement between the two in the vertical direction, avoiding movement interference caused by a rigid connection between the downward pressing driving part 52 and the supporting part 21. When the second supporting part 212 adjusts its position in the horizontal direction, the second connecting part drives the first connecting part and the downward pressing driving part 52 to move as a whole, ensuring that the bending cooperation position between the downward pressing head 51 and the second supporting part 212 remains constant. This sliding structure enables the downward pressing driving system to not only adapt to the height change of the supporting part 21, but also follow the horizontal adjustment of the second supporting part 212 to achieve linkage, maintaining the accuracy of the bending action.

[0074] In some specific embodiments, the first connecting part can be designed as a component with a T-shaped slider, and the second connecting part is correspondingly provided with a T-shaped sliding groove, and the two realize up-and-down sliding through a slide rail. Threaded holes can be provided at the bottom of the second connecting part, and it is fixedly connected to the top surface of the second supporting part 212 by bolts.

[0075] Compared with the prior art, in the traditional solution, a fixed connection structure is adopted between the downward pressing driving part 52 and the supporting part 21. When the supporting part 21 moves up and down, it is easy to cause the driving mechanism to be deformed by force or the position to shift. This solution adopts a split sliding connection structure, which not only realizes dynamic compensation during the lifting process, but also ensures position synchronization during horizontal adjustment, effectively solving the problems of reduced bending accuracy and limited equipment adaptability existing in the traditional rigid connection.

[0076] Through the above technical solutions, the present application realizes a stable connection between the downward pressing driving system and the adjustable supporting structure, avoids mechanical interference and stress concentration during the lifting process of the supporting part 21, and at the same time maintains the precise alignment of the bending structure 5 during horizontal adjustment, ensuring the consistency of the bending angles of the pins of the electronic device 200, so that the equipment can adapt to the processing requirements of electronic devices 200 with different thicknesses and pin spacings.

[0077] The present application further proposes a combined structure of a driving motor, a threaded rod, and a slider. The driving motor is arranged on the base 1, the threaded rod is fixedly connected to the output end of the driving motor, and the slider is threadedly connected to the threaded rod and fixedly connected to the limiting member 31.

[0078] Among them, the driving motor refers to a device that provides linear motion power. Specifically, a stepper motor can be used to achieve it, and the displacement amount can be accurately controlled by controlling the number of turns of the motor. The threaded rod refers to a transmission component that converts rotational motion into linear motion. Specifically, a trapezoidal threaded rod can be used to achieve it, and its pitch determines the movement accuracy. The slider refers to a moving component that cooperates with the threaded rod. Specifically, a copper nut seat can be used to achieve it, and the rotational motion is converted into linear displacement through meshing with the threaded rod.

[0079] Specifically, after the driving motor is powered on, it drives the threaded rod to rotate, and the slider moves axially under the guidance of the spiral groove of the threaded rod. Since the slider is rigidly connected to the limiting member 31, the limiting member 31 moves synchronously with the slider, thereby changing the width dimension of the limiting channel 4. The self-locking characteristic of the screw drive enables the slider to maintain its position fixed after power supply is stopped, preventing displacement deviation caused by vibration or external force. By setting the proportional relationship between the rotation angle of the driving motor and the displacement amount of the slider, precise control of each adjustment action can be achieved.

[0080] The above description is only an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
