Description

Technical Field

[0001] This invention relates to the field of pin bending technology, specifically to an adjustable electronic component pin bending device. Background Technology

[0002] Currently, there are several main methods for bending the leads of electronic components: 1. Manual bending: Operators use pliers or other hand tools to bend the pins one by one. This method is difficult to achieve the required precision and consistency, and as the number of times the work is done increases, worker fatigue intensifies, and work efficiency decreases.

[0003] 2. Stamping bending equipment: This type of equipment uses an upper and lower die. The component is placed in the positioning groove of the lower die, with the lead extending out of the groove. The upper die presses down, causing the lead to bend upwards under the pressure of the outer edge of the positioning groove. While this type of equipment improves efficiency, it has many problems.

[0004] 3. Rotary / oscillating bending equipment: The bending of the pin is achieved by rotating the rotating plate or bending claw. Some equipment can change the bending angle by adjusting the rotation angle.

[0005] CN117960949B discloses an electronic component lead bending device. This device improves overall work efficiency by simultaneously limiting and bending multiple capacitors. The limiting method also ensures the stability of the capacitors during bending, preventing unusable capacitors due to poor lead bending quality. To address the issue in existing technologies where metal leads exhibit elastic recovery after bending, leading to deviations between the actual and expected bending angles, current equipment lacks an effective compensation mechanism for the springback effect. Summary of the Invention

[0006] The technical solution provided by this invention is as follows: An adjustable electronic component pin bending device, comprising: The equipment base is a hollow frame structure. A feeding device is fixedly connected to the top of the equipment base. A fixed end of a telescopic rod is fixedly connected to the top of the feeding device. An extrusion seat is fixedly connected to the movable end of the telescopic rod. A rotating device is fixedly connected to the inner wall side of the equipment base. A bending device is fixedly connected to the side of the rotating device. The receiving box is configured as a guide structure and is located on one side of the bottom of the rotating device; Preferably, the rotating wheel is configured as a circular rotating frame structure, the side of the rotating wheel is provided with a through hole, and the side of the rotating wheel is rotatably connected to the inner wall side of the equipment base; A fixing frame, wherein the fixing frame is configured as a horizontal through-type structure, and the bottom of the fixing frame is fixedly connected to the top of the rotating wheel; A compression spring, wherein the compression spring is configured as a symmetrical structure and is disposed on the inner wall side of the fixing frame; A guide plate is configured as a guide structure at a certain angle to the top of the extrusion spring. A guide groove is provided on the side of the guide plate. The chip is fed along the top of the feeding device and slides along the top of the feeding device. The chip enters the bottom of the extrusion seat. Driven by the movable end of the telescopic rod, the extrusion seat is lowered. The lowering of the extrusion seat causes the workpiece to enter the interior of the rotating device. Under the guidance of the guide plate, it is pressed down and squeezed into the inner wall side of the extrusion spring. The chip is guided and squeezed along the side of the extrusion spring and fixed to the bottom of the inner wall of the fixing frame.

[0007] The rotating wheel rotates under the support of the equipment base. Activating the bending device causes the rotating wheel to rotate. The through-hole design facilitates airflow and visual observation during rotation, allowing for real-time monitoring of the workpiece's bending status. After bending, the leads detach from the inner wall of the mounting bracket under the drive of the bending device and enter the receiving box for collection, thus completing the chip lead bending. The rotating wheel drives multiple chips to slide along the side of the bending device to achieve progressive bending. Compared to the traditional direct bending method, this gradually eliminates stress, preventing springback after lead bending.

[0008] Preferably, the rotating bracket is configured as a hollow frame structure, and a guide hole is provided on the side of the rotating bracket. The guide hole is configured as a guide structure with a certain arc. The fixed end of the first motor is fixedly connected to the side of the rotating bracket. The drive shaft of the first motor is fixedly connected to a drive gear. The top of the drive gear meshes with a first driven gear. The bottom of the drive gear meshes with a pressing component. The bottom of the rotating bracket is fixedly connected to a guide frame through a bracket.

[0009] Preferably, the side of the guide frame is fixedly connected to the side of the receiving box, the bottom of the guide frame is fixedly connected to the bottom of the inner wall of the equipment base, the side of the first driven gear is fixedly connected to the side of the rotating wheel, and the rotating wheel is rotatably connected to the side of the rotating bracket through a bracket.

[0010] Preferably, the extrusion assembly includes a second driven gear, the side of which is rotatably connected to the rotating end of an electric screw via a bracket, the fixed end of the electric screw being rotatably connected to the side of a rotating bracket via a bracket, a rotating wheel being fixedly connected to the side of the second driven gear, an extrusion wheel being fixedly connected to the bottom of the rotating wheel, bending grooves being provided on the sides of both the rotating wheel and the extrusion wheel, and a stripping frame being fixedly connected to the side of the rotating wheel away from the second driven gear.

[0011] Preferably, the unloading rack is configured as a forked structure, the bending groove is configured as a guiding structure, the top of the second driven gear meshes with the bottom of the driving gear, the first motor is started, the drive shaft of the first motor rotates to drive the driving gear, the driving gear rotates to drive the first driven gear to rotate, the first driven gear rotates to drive the rotating wheel to rotate, the bottom of the driving gear rotates to drive the extrusion assembly to rotate, and the second driven gear rotates to drive the rotating wheel to rotate.

[0012] The rotating wheel drives the extrusion wheel and bending groove to move, extruding and bending the part of the pin that has moved to the top of the guide frame. The eccentric setting of the extrusion wheel increases the extrusion force, thereby preventing the pin from springing back after bending. After the chip pin is bent, the rotating wheel drives the stripping frame to move and extrude the top of the chip downward, thereby pushing the chip out of the fixed frame and completing the automatic stripping. Compared with traditional equipment, the bending groove makes it easier to extrude and bend the pin in one direction, and the eccentric setting of the extrusion wheel makes it easier to increase the extrusion force and avoid springback.

[0013] Preferably, the guide frame includes a guide base, and an arc-shaped frame is fixedly connected to the top of the guide base, and an extrusion groove is formed on the top of the arc-shaped frame.

[0014] Preferably, the arc-shaped frame is configured as an involute guide structure, and the bottom of the guide base is fixedly connected to the bottom of the inner wall of the equipment base. The guide base supports the arc-shaped frame. When the electric screw is started, the rotating part of the electric screw rotates and drives the second driven gear to slide along the inner wall side of the guide hole through the thread. The pin slides along the top of the arc-shaped frame, gradually increasing the extrusion force on the pin for pre-bending. The arc of the arc-shaped frame is configured as an involute guide, so that when the second driven gear slides along the inside of the guide hole, it changes the contact point between the extrusion wheel and the top of the arc-shaped frame, thereby adapting to the bending of pins of different sizes.

[0015] The extrusion groove is designed in conjunction with the bending groove to bend the chip into a specific shape. When the chip is loaded, the telescopic rod is activated. The movable end of the telescopic rod drives the lower pressure bracket to descend. The descending lower pressure bracket extrudes and guides the top of the chip. The stepped plate design changes the bottom of the lower pressure bracket into an extrusion plate structure of different heights, which facilitates the extrusion of the chip while simultaneously extruding and targeting the pins, making it easier to position the pins.

[0016] Preferably, the extrusion seat includes a lower pressure bracket, the bottom of the lower pressure bracket is provided with a stepped plate, the top of the lower pressure bracket is fixedly connected to the movable end of the telescopic rod, and the side of the lower pressure bracket is slidably connected to the inner wall side of the feeding device.

[0017] Preferably, the feeding device includes a sliding frame, a stepped base is fixedly connected to the inner side of the sliding frame, a discharge hole is opened at one end of the inner side of the sliding frame, a guide strip is fixedly connected to the top of the sliding frame, a feed pipe is fixedly connected to the top of the guide strip, a drive assembly is fixedly connected to the side of the sliding frame, and the guide strip is configured as a guide structure.

[0018] Preferably, the drive assembly includes a second motor, a spring is fixedly connected to the drive shaft of the second motor, a drive wheel is fixedly connected to the side of the spring, a conveyor belt is sleeved on the side of the drive wheel, an extrusion strip is fixedly connected to the top of the conveyor belt, and the conveyor belt is located at the bottom center of the stepped base.

[0019] The fixed end of the second motor is fixedly connected to the side of the sliding frame. The chip slides along the inside of the feed tube into the inner wall of the sliding frame. The drive assembly is activated, and the drive shaft of the second motor drives the spring to rotate. The rotation of the spring drives the drive wheel to rotate, and the rotation of the drive wheel drives the conveyor belt to move.

[0020] The conveyor belt moves, causing the extrusion bar to move. The extrusion bar extrudes and pushes the chip along its sides, causing the chip to slide along the top of the stepped base. The stepped height of the stepped base provides targeted support and protection for the pins. The guide bar guides and fixes the chip to the inner wall of the sliding frame. The chip is then fed by sliding down the inner wall of the discharge hole through the extrusion of the lower support. The spring mechanism provides elastic drive between the drive shaft of the second motor and the conveyor belt, preventing chip damage caused by direct drive.

[0021] The beneficial effects of the technical solution provided by this invention include: 1. The chip slides along the top of the feeding device to below the extrusion seat. The extrusion seat descends, guiding the chip into the rotating device. Under the action of the guide plate, the chip is pressed down and embedded inside the extrusion spring. The spring clamps the chip laterally, fixing it to the bottom of the mounting frame. The roller rotates on the base, and the bending device is activated accordingly. As the roller rotates, airflow is allowed through the through-hole to observe the internal situation, allowing for real-time monitoring of the lead bending process. After bending, the lead detaches from the inner wall of the mounting frame and falls into the receiving box, completing the bending process. The roller rotates continuously, causing multiple sets of chips to slide sequentially along the side of the bending device, achieving progressive bending. The stress during the bending process is gradually released, and lead springback is suppressed.

[0022] 2. A first motor drives a drive gear, which in turn drives a first driven gear to rotate the rotary wheel. Simultaneously, the bottom of the drive gear drives the extrusion assembly. A second driven gear drives a rotating wheel, which in turn moves the extrusion wheel and bending groove, bending the portion of the lead located at the top of the guide frame. The extrusion wheel is eccentrically positioned, increasing the extrusion pressure during bending and further preventing lead springback. After bending, the rotating wheel moves the stripper frame, pushing the chip downwards from the top, causing it to detach from the holder and automatically completing the unloading process. The bending groove performs unidirectional extrusion bending on the lead, and in conjunction with the eccentric extrusion wheel, springback is controlled.

[0023] 3. The guide base supports the arc-shaped frame. After the electric screw is started, the second driven gear slides along the side wall of the guide hole, and the pin slides along the top of the arc-shaped frame. The extrusion pressure gradually increases, achieving pre-bending. The arc-shaped frame adopts an involute profile. When the second driven gear slides, the contact point between the extrusion wheel and the top of the arc-shaped frame changes accordingly, which can accommodate pins of different sizes. The extrusion groove and bending groove cooperate to bend the pin into a specific shape. When the chip is loaded, the telescopic rod pushes the lower pressure bracket down. The top of the bracket extrudes the chip for guidance. The stepped plate creates extrusion surfaces of different heights at the bottom of the lower pressure bracket, which facilitates chip ejection and also positions and extrudes the pin.

[0024] 4. The chip slides into the sliding frame along the feed tube. The second motor drive shaft drives the drive wheel via a spring. The drive wheel moves the conveyor belt, and the pressing strips on the conveyor belt push the side of the chip. The chip slides along the top of the stepped base. The height difference of the stepped base provides support and protection for the pins. The guide strip keeps the chip positioned within the sliding frame. Finally, it is pressed by the lower support and slides down through the discharge hole to complete the feeding process. The spring connects the motor drive shaft and the conveyor belt, achieving elastic transmission and avoiding damage to the chip from rigid direct drive. Attached Figure Description

[0027] Example 1, please refer to Figures 1-2 This invention provides a technical solution: an adjustable electronic component pin bending device. A chip is fed along the top of a feeding device 2 and slides along the top of the feeding device 2. The chip enters the bottom of an extrusion seat 4. Driven by the movable end of a telescopic rod 3, the extrusion seat 4 descends. The descending extrusion seat 4 pulls the workpiece into the interior of a rotating device 5, and under the guidance of a guide plate 505, it is pressed and squeezed into the inner wall of an extrusion spring 504. The chip is guided and pressed along the side of the extrusion spring 504 and fixed to the bottom of the inner wall of a fixing frame 503. A rotating wheel 501 rotates under the rotational support of a base 1. The bending device 6 is activated, which drives the rotating wheel 501 to rotate. The through hole 502 facilitates air circulation and visual observation during the rotation of the rotating wheel 501, thereby enabling real-time monitoring of the bending status of the workpiece. After bending, the pins are separated from the inner wall of the fixing frame 503 under the drive of the bending device 6 and enter the receiving box 7 for collection, thus completing the pin bending of the chip. The rotating wheel 501 drives multiple sets of chips to slide along the side of the bending device 6 to achieve progressive bending. Compared with the traditional direct bending method, this gradually eliminates stress and prevents the pins from springing back after bending.

[0028] Example 2, please refer to Figures 1-4Based on the first embodiment, the first motor 602 is started. The drive shaft of the first motor 602 rotates, driving the drive gear 603. The drive gear 603 rotates, driving the first driven gear 604 to rotate. The first driven gear 604 rotates, driving the rotating wheel 501 to rotate. The bottom of the drive gear 603 rotates, driving the extrusion assembly 606 to rotate. 601 and the rotating bracket 601 fix the drive gear 603 and the extrusion assembly 606. The second driven gear 6061 rotates, driving the rotating wheel 6063 to rotate. The rotating wheel 6063 rotates, driving the extrusion wheel 6064 and the bending groove 6065 to move. The device moves the pins to the top of the guide frame 607 and presses and bends them. The eccentric setting of the pressing roller 6064 increases the pressing force to prevent the pins from springing back after bending. After the chip pins are bent, the rotating roller 6063 drives the stripper frame 6066 to move and press the top of the chip downward, thereby pushing the chip out of the inside of the fixed frame 503, thus completing the automatic stripping. Compared with traditional equipment, the setting of the bending groove 6065 facilitates unidirectional pressing and bending of the pins, and the eccentric setting of the pressing roller 6064 facilitates additional pressing force to avoid springback.

[0029] Example 3, please refer to Figures 1-6 Based on the second embodiment, the guide base 6071 supports the arc frame 6072. The electric screw 6062 is activated, and its rotating part rotates, driving the second driven gear 6061 to slide along the inner wall of the guide hole 605 via a thread. The pin slides along the top of the arc frame 6072, gradually increasing the pressure on the pin for pre-bending. The arc of the arc frame 6072 is set as an involute guide, so that when the second driven gear 6061 slides along the inside of the guide hole 605, it changes the relationship between the extrusion wheel 6064 and the arc. The contact point at the top of the formwork 6072 allows for bending of pins of different sizes. The extrusion groove 6073, in conjunction with the bending groove 6065, enables bending of specific shapes. When the chip is loaded, the telescopic rod 3 is activated, and the movable end of the telescopic rod 3 drives the lowering bracket 401 to descend. The descending lowering bracket 401 extrudes and guides the top of the chip. The stepped plate 402 changes the bottom of the lowering bracket 401 into an extrusion plate structure of different heights, which facilitates the extrusion of the chip while simultaneously extruding and specifically extruding the pins, making pin positioning easier.

[0030] Example 4, please refer to Figures 1-8Based on the third embodiment, the chip slides along the inside of the feed tube 205 into the inner wall of the sliding frame 201. The drive assembly 206 is activated, and the drive shaft of the second motor 2061 drives the spring 2062 to rotate. The rotation of the spring 2062 drives the drive wheel 2063 to rotate. The rotation of the drive wheel 2063 drives the conveyor belt 2064 to move. The movement of the conveyor belt 2064 drives the extrusion bar 2065 to move. The movement of the extrusion bar 2065 extrudes and extrudes the side of the chip, causing the chip to slide along the top of the stepped base 202. The stepped height of the stepped base 202 is set to provide targeted support and protection for the pins. The guide bar 204 guides and fixes the chip to the inner wall of the sliding frame 201. The chip is fed by sliding down the inner wall of the discharge hole 203 through the extrusion of the pressing bracket 401. The spring 2062 provides elastic drive between the drive shaft of the second motor 2061 and the conveyor belt 2064, avoiding chip damage caused by direct drive.
