Description

Technical Field

[0001] This utility model relates to the field of bending device technology, specifically a connector pin bending device. Background Technology

[0002] In the field of connector manufacturing, especially in the production of connectors with pins, accurately inserting metal pins into the connector insulation body and completing the fixing and shaping is a key process. Traditional production methods mostly rely on manual or semi-automatic equipment for pin insertion, riveting and bending operations. Manual operation is not only inefficient and costly, but also prone to quality problems such as incomplete pin insertion, weak riveting, and inconsistent bending angles due to human factors, making it difficult to guarantee the consistency and reliability of the products.

[0003] While some automated equipment has emerged to replace manual labor, these devices often suffer from poor overall coordination and disjointed processes. For example, the lack of unified and precise collaborative control between connector loading and positioning, pin separation and conveying, and subsequent riveting and bending actions results in slow production cycles and poor equipment stability. Furthermore, for the pin bending process, existing equipment often employs simple direct-push or oscillating structures, making it difficult to achieve complex and precise control of the circular bending path. There is still significant room for improvement in bending accuracy and product yield.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a connector pin bending device to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of this invention is to provide a connector pin bending device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connector pin bending device, comprising:

[0007] Workbench;

[0008] A conveyor channel, set on the workbench, is used to convey connectors;

[0009] A conveying mechanism, mounted on the workbench, is used to convey connectors to the conveying channel;

[0010] The feeding mechanism, set on the workbench, is used to transport the needles;

[0011] A pre-insertion mechanism, set on the worktable, is used to receive pins from the feeding mechanism and pre-insert them into the connector located on the conveyor channel;

[0012] The riveting mechanism, set on the worktable and downstream of the pre-pin insertion mechanism, is used to rivet the pins inserted into the connector.

[0013] The bending mechanism, located on the workbench and downstream of the riveting mechanism, is used to bend the riveted needles.

[0014] Specifically, by integrating connector conveying channels, conveying mechanisms, feeding mechanisms, pre-insertion mechanisms, riveting mechanisms, and bending mechanisms on the workbench, and having them work in tandem along the processing flow, a complete automated processing system is constructed. This achieves full-process integration and automation from automatic connector and pin feeding, precise pre-insertion, reliable riveting to final bending and forming, thereby significantly improving production efficiency and product consistency, while effectively reducing labor costs and the risk of operational errors.

[0015] Preferably, the conveying mechanism includes a linear feeder, a transfer component, and a pushing component; the linear feeder is set on the workbench and has a trough, the input end of which is used to receive connectors supplied externally; the transfer component is set at the beginning of the conveying channel and is used to transfer the connectors output by the linear feeder to the conveying channel; the pushing component is set on the conveying channel and is used to push the connectors along the conveying channel to the subsequent workstation.

[0016] Specifically, the conveying mechanism integrates a linear feeder, a transfer component, and a pushing component to construct an efficient and precise automated flow path for connectors. The linear feeder provides directional supply of connectors, the transfer component is responsible for accurately transferring and positioning the connectors to the starting position of the conveying channel, and then the pushing component steadily pushes the connectors to subsequent processing stations according to a set rhythm. This ensures the continuity of material transfer, positioning accuracy, and operational reliability throughout the entire pin insertion and bending process, laying a solid foundation for the stable execution of subsequent pin insertion, riveting, and bending processes.

[0017] Preferably, the transfer component includes:

[0018] The support frame is fixed to the conveyor channel;

[0019] The transfer trough, slidably mounted on the bracket, is used to receive the connector from the linear feeder;

[0020] The first drive cylinder is mounted on the bracket, and its drive end is connected to the transfer trough, which is used to drive the transfer trough to move between the receiving position and the discharging position.

[0021] The positioning pin is fixed on the bracket. When the transfer trough moves to the receiving position, the receiving connector is blocked by the positioning pin to achieve precise positioning.

[0022] Specifically, the transfer assembly achieves a smooth transition and precise positioning of the connector from feeding to positioning through its structural design. The bracket fixed on the conveyor channel provides a stable installation foundation for the entire assembly. The sliding transfer trough, driven by the first drive cylinder, can accurately reciprocate between the receiving and unloading stations to complete the gripping and transfer of the connector. The positioning pin fixed on the bracket physically blocks and forcibly limits the connector when the transfer trough reaches the receiving position, effectively eliminating the positional deviation caused by cumulative errors or inertia. This ensures that each connector is in the preset precise position before entering the next process, thus providing a reliable guarantee for subsequent high-precision pin insertion operations.

[0023] Preferably, the push component includes:

[0024] A push slider is slidably installed inside the conveyor channel;

[0025] The second drive cylinder is fixed at the end of the conveying channel. Its drive end is connected to the push slider and is used to drive the push slider to slide back and forth to push the connectors forward one by one.

[0026] Specifically, this design achieves precise step-by-step conveying of connectors within the conveying channel. A second drive cylinder, fixed at the end of the channel, provides a stable and reliable power source for the pushing action, driving a sliding pusher within the channel to reciprocate linearly. This allows for stable and controllable stroke and thrust, precisely pushing each connector to the next processing station. This structural design not only achieves complete automation of the conveying process, effectively improving production efficiency, but its simple and reliable mechanical structure also ensures the repeatability and long-term stability of the pushing action, providing a crucial guarantee for the continuous and reliable operation of the entire device.

[0027] Preferably, the feeding mechanism includes:

[0028] A direct vibrating feeder is installed on the workbench;

[0029] The conveyor plate, mounted on the vibrating feeder, has its input end used to receive externally supplied needles and to orient the needles to the pre-insertion mechanism.

[0030] Specifically, this design achieves efficient and orderly needle feeding. The high-frequency, low-amplitude vibration generated by the vibrating feeder automatically orients and sorts the randomly piled needles, allowing them to move neatly forward along the conveyor plate on the feeder and ultimately be stably conveyed to the receiving position of the pre-insertion mechanism in the correct preset posture. This structural design not only achieves complete automation of the needle feeding process, significantly improving feeding efficiency and continuity, but more importantly, it ensures the consistency and accuracy of the posture of each needle before entering the critical insertion process. This provides a crucial foundation for subsequent precise insertion, reliable riveting, and bending, thereby effectively improving overall production quality and stability.

[0031] Preferably, the pre-insertion mechanism includes:

[0032] A sliding seat is slidably mounted on the worktable;

[0033] A fixture, mounted on a sliding seat, is used to receive needles from the feeding mechanism;

[0034] The third drive cylinder is set on the worktable, and its drive end is connected to the sliding seat. It is used to drive the sliding seat and the fixture to move closer to or away from the conveying channel.

[0035] The pusher plate is slidably mounted on the sliding seat;

[0036] The fourth drive cylinder, located on the worktable, is used to drive the pusher plate to push out the pins in the fixture and insert them into the connector;

[0037] A positioning component, disposed on the delivery channel and opposite to the fixture, is used to position the other end of the needle during insertion.

[0038] Specifically, the pre-insertion mechanism achieves fully automated precision operation of pin pickup, positioning, and insertion. After receiving the pin from the feeding mechanism, the fixture, driven by the third drive cylinder, smoothly moves the pin to the position aligned with the connector on the conveyor channel via a sliding seat. Simultaneously, the positioning component firmly presses the connector from the opposite side, providing a reliable reference for pin insertion. Subsequently, the fourth drive cylinder precisely drives the pusher plate, smoothly and accurately pushing the pin in the fixture into the predetermined socket of the connector. This composite action design ensures the positional accuracy and operational reliability of the pin insertion process, effectively avoiding quality problems such as pin bending or incomplete insertion, and providing qualified semi-finished products for subsequent riveting and bending processes.

[0039] Preferably, the positioning component includes:

[0040] Mounting base, fixed on the conveyor channel;

[0041] The top plate is slidably mounted on the mounting base for pressing the connector from one side;

[0042] The transmission plate is slidably mounted on the mounting base and connected to the end of the top plate;

[0043] The boss plate is slidably mounted on the mounting base;

[0044] The fifth drive cylinder is mounted on the mounting base and is used to drive the boss plate to move. The boss plate pushes the transmission plate and the top plate to move through the inclined plane or cam structure.

[0045] Specifically, the positioning component achieves precise positioning and reliable clamping of the connector through its unique transmission mechanism. The mounting base fixed on the conveyor channel provides a stable mounting foundation for the entire component. When the fifth drive cylinder drives the boss plate to move, the inclined surface or cam structure on the boss plate converts the vertical thrust into horizontal motion, which pushes the transmission plate to smoothly extend the top plate towards the connector, thereby precisely clamping the connector from one side. This lever-type transmission method not only achieves effective force transmission and amplification, ensuring sufficient and stable clamping force, but its compact structural design also saves installation space. This component provides a precise and reliable positioning reference for the pre-pin insertion process, effectively preventing the connector from shifting during the pin insertion process, ensuring the perpendicularity and positional accuracy of the pin insertion, and laying a solid foundation for the smooth progress of subsequent processes.

[0046] Preferably, the riveting mechanism includes:

[0047] The sixth drive cylinder is mounted on the worktable;

[0048] The riveting component is located at the drive end of the sixth drive cylinder and is used to perform riveting action on the end of the pin under the drive of the sixth drive cylinder.

[0049] Specifically, the riveting mechanism, through the cooperation of the sixth drive cylinder and the riveting component, achieves automated riveting of the pin ends inserted into the connector. The sixth drive cylinder, located on the worktable, provides stable and controllable power output for the riveting action, driving the riveting component at its end to precisely perform the forward pressing action, causing the pin ends to produce the expected plastic deformation. This structural design not only achieves complete automation of the riveting process and significantly improves production efficiency, but more importantly, through the stability and repeatability of the cylinder drive, it ensures that the riveting pressure and deformation depth borne by each pin remain highly consistent, thereby effectively improving the mechanical strength of the pin fixation and the reliability of the electrical connection, providing a solid guarantee for the subsequent bending process and the final quality of the product.

[0050] Preferably, the bending mechanism includes:

[0051] Double semi-circular slide rails, fixed on the worktable;

[0052] A semi-circular toothed ring is slidably set within a double semi-circular slide rail;

[0053] The rack slides through the support of the worktable or double semi-circular slide rail and meshes with the semi-circular gear ring.

[0054] The bending component is fixed to the end of the semi-circular toothed ring and bends the pins as it rotates.

[0055] The seventh drive cylinder is set on the worktable and is used to drive the rack to move linearly, which in turn drives the semi-circular gear ring and the bent part to rotate through the rack.

[0056] The lifting frame slides through the support of the worktable or double semi-circular slide rails;

[0057] The pressing component, located on the lifting frame, is used to press and fix the connector when the pins are bent.

[0058] The eighth drive cylinder, located on the worktable, is used to drive the lifting frame to move up and down, thereby driving the end pressing component to press and fix the connector.

[0059] Specifically, the bending mechanism achieves precise bending motion control through a unique combination of gear and rack transmission and arc-shaped guide rails. The double semi-circular slide rails fixed to the worktable provide precise arc-shaped motion trajectory guidance for the semi-circular gear ring. When the seventh drive cylinder drives the rack in linear motion, the linear motion is precisely converted into rotational motion at a set angle through meshing with the semi-circular gear ring, driving the bending component fixed to the end of the gear ring to complete the bending operation on the pins. This mechanism cleverly utilizes the high-precision characteristics of gear and gear ring transmission to ensure the consistency and repeatability of the bending angle. Its arc-shaped slide rail guide structure effectively eliminates motion backlash, making the bending process smoother and more reliable, thus significantly improving product forming quality and processing consistency, fully meeting the process requirements of high-precision electronic connector manufacturing.

[0060] Preferably, auxiliary equipment is also included;

[0061] Auxiliary equipment includes:

[0062] A connector feeding device, located near the workbench, is used to supply connectors to the linear feeder of the conveying mechanism;

[0063] A needle feeding device is installed near the workbench and is used to supply needles to the feeding mechanism;

[0064] The unloading mechanism, located at the end of the conveyor channel, is used to receive and transfer the finished products that have been processed.

[0065] Specifically, the connector feeding device and pin feeding device located near the workbench continuously and stably supply raw materials to the linear feeder and feeding mechanism of the conveying system, ensuring the continuity of the production process. Simultaneously, the unloading mechanism at the end of the conveying channel automatically receives and transfers the finished products, achieving full automation from raw material supply to finished product output. This auxiliary equipment significantly reduces manual intervention, improves production efficiency, reduces labor intensity, and ensures consistent product quality through stable automated conveying.

[0066] Compared with the prior art, the present invention provides a connector pin bending device, which has the following advantages:

[0067] Through integrated automation design, multiple processes such as automatic feeding, precise conveying, coordinated pin insertion, reliable riveting, and precision bending of connectors and pins are seamlessly connected to build a complete fully automated production line. This completely replaces the traditional operation mode that relies on manual or semi-automatic equipment. Through precise coordination and control between various functional modules, it not only significantly improves production efficiency and greatly reduces labor costs and labor intensity, but more importantly, it effectively solves the previous quality problems of incomplete pin insertion, weak riveting, and inconsistent bending angles. This ensures the consistency of product processing accuracy, mechanical strength, and electrical connection reliability, fundamentally improving the product qualification rate and stability.

The high-frequency, low-amplitude vibration generated by the vibratory feeder 410 automatically orients and sorts the randomly piled needles, allowing them to move neatly forward along the conveyor plate 420 on the vibratory feeder 410. Finally, they are stably conveyed to the receiving position of the pre-insertion mechanism 50 in the correct preset posture.

[0135] Specifically, the bending mechanism 70 achieves precise bending action control through a unique combination of gear and rack transmission and arc-shaped guide rails. The double semi-circular slide rails 710, fixed on the worktable 10, provide precise arc-shaped motion trajectory guidance for the semi-circular gear ring 720. When the seventh drive cylinder 750 drives the rack 730 in linear motion, the linear motion is precisely converted into rotational motion at a set angle through meshing with the semi-circular gear ring 720, driving the bending component 740 fixed to the end of the gear ring to complete the bending operation of the pins. This mechanism cleverly utilizes the high-precision characteristics of gear and gear ring transmission to ensure the consistency and repeatability of the bending angle. Its arc-shaped slide rail guide structure effectively eliminates motion backlash, making the bending process smoother and more reliable, thereby significantly improving product forming quality and processing consistency, fully meeting the process requirements of high-precision electronic connector manufacturing.

[0136] Preferably, it also includes auxiliary equipment 80;

[0137] Auxiliary equipment 80 includes:

[0138] A connector feeding device 810 is provided adjacent to the worktable 10 for supplying connectors to the linear feeder 310 of the conveying mechanism 30.

[0139] A needle feeding device 820 is installed adjacent to the worktable 10 and is used to supply needles to the feeding mechanism 40.

[0140] The unloading mechanism 830 is located at the end of the conveying channel 20 and is used to receive and transfer the finished products that have been processed.

[0141] Specifically, the connector feeding device 810 and pin feeding device 820, located adjacent to the workbench 10, continuously and stably supply raw materials to the linear feeder 310 and feeding mechanism 40 of the conveying mechanism 30, respectively, ensuring the continuity of the production process. Simultaneously, the unloading mechanism 830, located at the end of the conveying channel 20, can automatically receive and transfer the finished products, realizing full automation from raw material supply to finished product output. The configuration of this auxiliary equipment 80 significantly reduces manual intervention, improves production efficiency, reduces labor intensity, and ensures consistent product processing quality through stable automated conveying.

[0142] Working principle: The connector feeding device 810 and the pin feeding device 820 respectively transport the connector and pin into the device. The connector is output by the linear feeder 310 of the conveying mechanism 30 and is accurately transferred to the conveying channel 20 by the transfer component 320, and then gradually pushed by the pushing component 330. During this process, the feeding mechanism 40 orderly transports the pin into the fixture 520 of the pre-insertion mechanism 50. The fixture 520, driven by the third drive cylinder 530, carries the pin close to the connector. At the same time, the boss plate 564 of the positioning component 560, driven by the fifth drive cylinder 565, uses the vertical thrust it receives to pass through the inclined plane or cam structure. The mechanism is converted into a horizontal movement to press the connector, and then the fourth drive cylinder 550 drives the pusher plate 540 to insert the pins into the connector; the connector with the pins inserted is then conveyed to the riveting mechanism 60, where the sixth drive cylinder 610 drives the riveting part 620 at its end to precisely perform the forward pressing action to rivet the pin ends; finally, the seventh drive cylinder 750 of the bending mechanism 70 drives the rack 730 to move, which drives the semi-circular gear ring 720 that meshes with it to rotate in the double semi-circular slide rail 710, so that the bending part 740 completes the precision bending of the pins, and the finished product is finally output by the unloading mechanism 830, thus completing the fully automatic operation cycle.
