Description

Technical Field

[0001] This invention relates to the field of electronic component lead bending technology, specifically to an electronic component processing equipment. Background Technology

[0002] In the PCB assembly process, a large number of packaged devices, connectors and other electronic components adopt a double-row symmetrical pin layout. In order to adapt to the soldering and installation requirements of the circuit board, the two rows of pins on both sides of the component need to be bent outward by 90° to form a horizontal mounting structure.

[0003] Currently, most of the mainstream pin bending processing equipment in the industry has a single-sided bending structure, which can only complete the bending and forming of a single row of pins at a time.

[0004] The actual processing flow is as follows: the operator first positions and clamps the electronic components, and the equipment completes the 90° outward bending of one row of pins; after processing, the operator manually removes the components, manually flips the components, re-clamps and positions them, and then starts the equipment to perform the bending process on the other row of pins.

[0005] This processing method has many obvious drawbacks: Firstly, the components need to be clamped twice and manually flipped and placed once, resulting in many process steps, a long processing cycle for a single product, and low overall processing efficiency in mass production, making it difficult to meet the continuous operation requirements of automated production lines. Secondly, the two manual loading and unloading and flipping operations rely on manual intervention, which is labor-intensive and has high labor costs. Third, repeated disassembly and reassembly can easily cause component clamping misalignment, inconsistent bending references between the two bends, and quality problems such as deviation in bending angle of the pins on both sides and poor coplanarity of the pins, which increases the defect rate. Fourth, frequent manual handling of components can easily damage the pins and scratch the component's plastic package, causing damage to the product's appearance and electrical performance, making it difficult to guarantee product yield. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide an electronic component processing equipment to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electronic component processing equipment, including a main support, wherein a stepped groove for limiting and guiding the sliding of components is provided at the middle position of the top of the main support, the stepped groove is used to limit and guide the components, and provides a positioning channel for the stepping conveying of components; The main support is fixed with a support frame and a mounting frame. A bending mechanism is installed on the mounting frame. The bending mechanism includes a first bending plate and a second bending plate that perform reverse synchronous linear motion. The first bending plate and the second bending plate are used to perform bending and forming operations on the pins on both sides of the component, respectively. The bending mechanism also includes a motor, a hollow shaft, gears, a first toothed plate, and a second toothed plate mounted on a mounting frame; The output end of the motor is connected to a hollow shaft, and a gear is fixed to the outside of the hollow shaft. The first gear plate and the second gear plate mesh on both sides of the gear respectively. The first gear plate and the second gear plate are fixed to the first bending plate and the second bending plate respectively. The motor drives the gear to rotate, which can drive the first bending plate and the second bending plate to move in opposite synchronous linear motion to complete the bending. Two sets of guide blocks are fixed at the top of the support frame. The two sets of guide blocks extend into the first toothed plate and the second toothed plate respectively. The bottom of the first toothed plate and the second toothed plate are provided with sliding grooves that cooperate with the guide blocks, so as to guide the first toothed plate and the second toothed plate. The inner side of the support frame is fixed with an inner support mechanism located at the top of the stepped groove inside the main support frame, and the inner support mechanism includes an inner support plate fixedly connected to the support frame. The inner support mechanism is used to flexibly support the root of the pin from the inside of the component pin before the bending action is performed, so as to prevent the pin from shifting or being damaged during bending. The internal support mechanism also includes airbag strips, connecting pipes, air cylinders, fixing rings, spiral grooves, hexagonal transmission rods, friction wheels, friction rings, transmission columns, limit slide rods, and piston plates; The hollow rotating shaft has a fixed friction ring on its inner wall. The friction ring has a friction wheel inside it. The friction wheel slides axially and is radially limited and is sleeved on the outside of the hexagonal transmission rod. The lower end of the hexagonal transmission rod is connected to the transmission column. The air cylinder is fixed to the top of the inner support plate, and the fixing ring is fixed to the top of the air cylinder; Two sets of limiting slide rods are fixed to the outer wall of the transmission column, and a spiral groove matching the limiting slide rods is opened on the inner wall of the fixing ring; When the transmission column rotates, the limiting slide rod slides along the spiral groove, driving the transmission column to rise and fall synchronously in the axial direction. The bottom of the transmission column is fixed with a piston plate that extends into the air cylinder. The bottom of the air cylinder is connected to the airbag strips symmetrically arranged on both sides of the inner support plate through two connecting pipes located inside the inner support plate; The piston plate descends and compresses the air in the air cylinder. The airflow passes through the connecting pipe and fills the air bag strip, causing it to expand and clamp the inner side of the component pin. When the piston plate moves upward, the airbag strip depressurizes, contracts, and releases its pins. When the airbag strip expands to its maximum limit, relative slippage occurs between the friction wheel and the friction ring. The hollow rotating shaft can continue to drive the gear to rotate and drive the first bending plate and the second bending plate to complete the bending stroke. The inner support action and the bending action share the same motor power source and their timing does not interfere with each other. The conveying mechanism is arranged below the stepped groove of the main support. The conveying mechanism is used to drive the components to move intermittently in steps, so as to realize the automatic switching of components to different bending stations without the need for manual flipping and reassembly. The conveying mechanism is an intermittent step conveying structure. After a single shift, the component that has been bent on one side is conveyed to the first bending plate station, while the component to be processed is conveyed to the second bending plate station, so that the bending operation of the two components can be carried out simultaneously.

[0008] In summary, the present invention has the following main beneficial effects: 1. This invention realizes the intermittent continuous feeding of components through a conveying mechanism. The components are only loaded once, without the need for manual removal, flipping, and secondary clamping. The workpiece first moves to the second bending plate station to complete the bending of one side of the pins, and then automatically moves to the first bending plate station with the conveying mechanism to complete the bending of the other row of pins. At the same time, adjacent components can be bent simultaneously, forming an uninterrupted production line processing mode. 2. The bending mechanism and the inner support mechanism of this invention share the same motor as the power source. At the initial stage of bending, the hollow rotating shaft drives the friction wheel synchronously through the friction ring, and sequentially drives the hexagonal transmission rod, transmission column, and piston plate to compress the air inside the air cylinder. The airflow fills the air bag strip to make it expand, and flexibly supports and clamps the root of the pin from the inside of the two rows of pins of the component, and completes the limit fixation before the bending action contacts the pin.

[0009] Once the airbag strip has inflated to its full extent and the pins are completely fixed, the friction wheel and friction ring slip relative to each other, the inner support mechanism stops operating, and the motor can continue to drive the bending plate to complete the bending stroke. The clamping and bending actions share a common existing motor control circuit, with time separation and no interference between them; no manual contact with components is required throughout the entire processing, avoiding pin collisions and shell scratches, and steadily improving the yield of finished products.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0013] The embodiments of the present invention will now be described.

[0014] Example like Figure 1-9 As shown, an electronic component processing equipment includes a main support 1, which serves as the foundation for supporting all components of the machine. A stepped groove is provided at the top center of the main support 1. The stepped groove is used to place double-row pin electronic components, limit and guide the electronic components, and provide a stable positioning channel for the step-by-step conveying of the components.

[0015] The main support frame 1 is fixedly installed with a support frame 2 and a mounting frame 3 on its top surface. The support frame 2 is located in the area above the stepped groove, and the mounting frame 3 is arranged on the rear side of the support frame 2.

[0016] Two sets of guide blocks 201 are fixedly mounted on the top of the support frame 2. The two sets of guide blocks 201 extend forward into the first toothed plate 404 and the second toothed plate 406 of the bending mechanism 4, respectively. The bottom of the first toothed plate 404 and the second toothed plate 406 are provided with sliding grooves that match the shape of the guide blocks 201. The guide blocks 201 can play a sliding guiding and constraining role for the reciprocating linear motion of the first toothed plate 404 and the second toothed plate 406.

[0017] The bending mechanism 4 is assembled on the mounting frame 3. The bending mechanism 4 includes a motor 401, a hollow rotating shaft 402, a gear 403, a first toothed plate 404, a first bending plate 405, a second toothed plate 406, and a second bending plate 407. The motor 401 is fixed on the upper part of the mounting frame 3. The output shaft of the motor 401 is coaxially and fixedly connected to the hollow rotating shaft 402. The gear 403 is fixedly sleeved on the outside of the hollow rotating shaft 402. The left and right sides of the gear 403 are respectively engaged with the first toothed plate 404 and the second toothed plate 406. The lower end of the first toothed plate 404 is fixedly connected to the first bending plate 405, and the lower end of the second toothed plate 406 is fixedly connected to the second bending plate 407. The motor 401 drives the hollow shaft 402 and gear 403 to rotate synchronously. The gear 403 drives the toothed plates on both sides to move in opposite synchronous linear motion. The first bending plate 405 and the second bending plate 407 move synchronously towards each other, respectively performing a 90° outward bending forming operation on the two rows of pins on both sides of the electronic component.

[0018] An inner support mechanism 5 is fixedly installed inside the support frame 2. The inner support mechanism 5 is located at the top of the stepped groove inside the main support frame 1. The inner support mechanism 5 includes an inner support plate 501, an airbag strip 502, a connecting pipe 503, an air cylinder 504, a fixing ring 505, a spiral groove 506, a hexagonal transmission rod 507, a friction wheel 508, a friction ring 509, a transmission column 510, a limiting slide rod 511, and a piston plate 512. The inner support plate 501 is fixedly connected to the bottom of the support frame 2. The air cylinder 504 is fixedly installed on the top of the inner support plate 501. The fixing ring 505 is locked and fixed at the upper opening of the air cylinder 504. The inner wall of the fixing ring 505 is machined into a spiral groove 506.

[0019] A friction ring 509 is fixedly installed on the inner wall of the hollow rotating shaft 402. The inner cavity of the friction ring 509 is in frictional contact with a friction wheel 508. The friction wheel 508 is fitted on the outside of the hexagonal transmission rod 507. The friction wheel 508 and the hexagonal transmission rod 507 are radially limited and axially slidable. The lower end of the hexagonal transmission rod 507 is fixedly connected to the top end of the transmission column 510. Two sets of limiting slide rods 511 are fixed on the outer wall of the transmission column 510. The two sets of limiting slide rods 511 are embedded in the spiral groove 506 on the inner wall of the fixed ring 505. A piston plate 512 is fixed at the bottom end of the transmission column 510. The piston plate 512 extends into the inner cavity of the air cylinder 504 in a sealed manner.

[0020] The bottom of the air cylinder 504 is connected to two connecting pipes 503. The two connecting pipes 503 pass through the inside of the inner support plate 501. The ends of the connecting pipes 503 are respectively connected to a set of airbag strips 502. The two sets of airbag strips 502 are symmetrically arranged on the left and right sides of the inner support plate 501.

[0021] The conveying mechanism 6 is arranged below the stepped groove of the main support 1. The conveying mechanism 6 adopts an intermittent step conveying structure to continuously drive the electronic components inside the stepped groove to move forward intermittently, so that the components are automatically switched to the second bending plate 407 station and the first bending plate 405 station. The components do not need to be manually removed, flipped, or re-clamped throughout the process.

[0022] The working principle of this invention is as follows: The main support 1 serves as the overall installation base of this device, and a stepped groove is formed at the middle position of the top of the main support 1. The cross-sectional shape of the stepped groove is consistent with the cross-sectional shape of the component whose pins are to be bent. Thus, the external feeding device can sequentially feed the arranged components into the stepped groove in the main support 1. With the intermittent operation of the conveying mechanism 6, multiple groups of arranged components can advance in a step-by-step manner. When the first component enters the main support 1 and moves to the position corresponding to the second bending plate 407, the bending mechanism 4 is started. The motor 401 of the bending mechanism 4 drives the gear 403 to rotate through the hollow rotating shaft 402. Then, the gear 403 meshes with the first toothed plate 404 and the second toothed plate 406 on both sides to move in opposite directions. Then, the second toothed plate 406 can move to bend one row of pins of the component. Prior to this, when the hollow shaft 402 rotates, the hollow shaft 402 will first drive the friction wheel 508 to rotate through the friction ring 509. The rotating friction wheel 508 will then drive the hexagonal transmission rod 507, which is radially limited and axially slidingly connected to it, to rotate. The rotation of the hexagonal transmission rod 507 will drive the transmission column 510 to rotate inside the fixed ring 505. Two sets of limiting slide rods 511 are fixed on the outside of the transmission column 510, and a spiral groove 506 that cooperates with the two sets of limiting slide rods 511 is opened on the inner wall of the fixed ring 505. At the same time, a piston plate 512 extending into the air cylinder 504 is fixed at the bottom of the transmission column 510. In other words, when the transmission column 510 rotates radially, it will simultaneously descend axially under the cooperation of the limiting slide rod 511 and the spiral groove 506. The descent will drive the piston plate 512 to descend axially inside the air cylinder 504, and then the air at the bottom of the air cylinder 504 will be forced into the two sets of airbag strips 502 through the two sets of connecting pipes 503. Since the two sets of airbag strips 502 are located on both sides of the inner support plate 501, when the airbag strips 502 expand, they can fix and limit the two rows of pins of the component from the inside, thus ensuring that the second bending plate 407 will not damage the root of the pins during the bending process. Furthermore, when the airbag strip 502 expands to its maximum extent, the second bending plate 407 is in contact with the pins. As the gear 403 continues to rotate, the bending of a row of pins is completed. At this time, the hollow shaft 402 continues to rotate, which will drive the friction ring 509 to continue to rotate. The friction ring 509 and the friction wheel 508 slip relative to each other, so there will be no interference with the pin bending action. After the first component's pins are bent, the bending mechanism 4 rotates in the opposite direction, causing the bending mechanism 4 to reset as a whole. At the same time, the piston plate 512 of the inner support mechanism 5 rises inside the air cylinder 504, thereby releasing the expansion of the air bag strip 502. At this time, in conjunction with the step-by-step conveying of the conveying mechanism 6, the first component moves to the first bending plate 405, while the subsequent second component continues to move to the second bending plate 407. At this time, the bending mechanism 4 is restarted. In the early stage of operation of the bending mechanism 4, the two sets of airbag strips 502 will simultaneously support and fix the two rows of pins of the two components. Then the first bending plate 405 will bend the other row of pins of the first component, and the second bending plate 407 will bend the row of pins of the second component. In this way, the equipment can continuously perform sequential bending operations on the two rows of pins of the components. In summary, the present invention features a double bending station with a symmetrically arranged first bending plate 405 and a second bending plate 407, which, together with a stepping conveyor mechanism 6, enables continuous stepping feeding of components. After a single component is loaded, the bending station is automatically switched by the conveyor mechanism 6, eliminating the need for manual removal, flipping, and secondary clamping of components throughout the entire process. The equipment can simultaneously perform different pin bending actions on two components. After the preceding component completes the single-sided bending, it is automatically transferred to another bending station by the conveyor mechanism 6 to complete the remaining pin bending. The subsequent material enters the first bending station for processing at the same time, forming a continuous production line mode. This completely eliminates the intermediate waiting process of two clamping and manual flipping and picking in the traditional process. The processing cycle of a single piece is significantly shortened, and the overall capacity is greatly improved under mass production conditions. It can be directly connected to automated upstream and downstream production lines to meet the needs of large-scale continuous production. The overall operation of the equipment is uniformly scheduled by the existing PLC control system. It is equipped with conventional electrical control components such as photoelectric sensors, servo drive motors, pneumatic control valves, and timing control modules to realize the timing linkage of bending, internal support fixing, and conveying actions. All positioning, clamping, bending, and feeding processes are completed automatically. Operators only need to replenish materials and inspect the equipment periodically. This eliminates the need for dedicated operators to repeatedly pick up, flip, and re-clamp parts in traditional processes, effectively reducing the labor intensity of the job and long-term labor production costs. The inner support mechanism 5 and the bending mechanism 4 operate synchronously. Before the bending action is started, the airbag strip 502 completes the pin support limit first. During the bending process, the pin root is subjected to uniform force, which effectively avoids defects such as inconsistent bending angles of pins on both sides and excessive pin coplanarity, and greatly reduces the product defect rate. The transmission and friction transmission clutch structure of the air cylinder 504 and piston plate 512 of the inner support mechanism 5 share a power source with the bending drive of the whole machine. There is no need to add additional independent drive electrical components, which fully reuses the existing motor and transmission control circuit and simplifies the overall electrical control layout of the machine. The internal support clamping action and the bending action are separated by the friction transmission pair. After the airbag strip 502 expands to the position, the friction wheel 508 and the friction ring 509 slip and rotate freely. The bending mechanism 4 can continue to complete the bending stroke independently. The two sets of actions share the same motor 401 drive and the same existing motor control circuit. There is no need to add an independent control axis and matching electrical control components, which reduces the difficulty of multi-axis synchronous control debugging. The whole machine moves smoothly, the failure rate is lower, and the continuous fault-free operation time of the equipment is extended. The equipment drive end uses mature existing electromechanical components such as general motor 401 and gear 403 meshing transmission. The clutch structure composed of friction wheel 508 and friction ring 509 can reuse conventional torque friction transmission standard parts. The matching pneumatic control circuit and timing detection sensing element are all industry-standard existing control components, and there is no need to customize special electrical control components.
