Description

Technical Field

[0001] This application relates to the field of pin bending technology, and in particular to a pin bending device for electrical connectors. Background Technology

[0002] Connectors are indispensable key components in modern electronic devices, and their precision and reliability directly affect the performance of the entire device. In particular, some electrical connectors used in special applications not only need to be precisely assembled with the housing, but also need to undergo one or even multiple precise bends to adapt to specific mating angles and spatial layouts.

[0003] Currently, the manufacturing process for these electrical connectors, which involves pin assembly and multiple bending processes, generally adopts a separate workstation model. Specifically, the entire production process is divided into multiple independent, single-function workstations. For example, the assembly station: Individual pins are pressed or inserted into the plastic housing manually or using simple semi-automatic equipment, completing the initial assembly of the terminals. The bending station: The assembled terminals are transferred manually or via a simple conveyor belt to another independent bending machine for the first bending. If a second bending is required, it may need to be transferred again to a third machine.

[0004] However, this traditional separate production model has the following inherent technical defects that are difficult to overcome:

[0005] Low production efficiency and lengthy processes: Materials need to be frequently transferred and waited for between different workstations, resulting in a slow production cycle and a large amount of intermediate work-in-process inventory between workstations, which ties up a lot of space and capital.

[0006] Accumulated errors lead to poor accuracy: Each workstation transfer involves a secondary gripping and positioning of the workpiece. Tiny positioning errors generated during this process accumulate. For example, if the pin insertion position in the assembly workstation has a tolerance of ±0.05mm, and this ±0.05mm tolerance is introduced during the secondary positioning in the bending workstation, the final bending position accuracy will significantly decrease, making it difficult to meet the requirements of high-precision connectors.

[0007] In summary, this separate production model has become a technical bottleneck restricting the improvement of production efficiency and quality of high-precision, complex-structure electrical connectors. Utility Model Content

[0008] This application provides an electrical connector pin bending device to solve the problem of low production efficiency caused by the difficulty in simultaneously achieving automated assembly and bending.

[0009] An electrical connector pin bending device, comprising:

[0010] Base;

[0011] The feeding mechanism includes a housing conveying assembly and a pin conveying assembly. The housing conveying assembly is located at one end of the base along its length, and the pin conveying assembly is located on the base. The housing conveying assembly can convey housings, and the pin conveying assembly can convey pins.

[0012] An assembly mechanism is provided on the base and located on one side of the housing conveying assembly along the length direction. The assembly mechanism is capable of receiving the housing and the pin and assembling and fixing them to form a terminal.

[0013] A bending mechanism is provided on the base and located on the side of the assembly mechanism away from the housing conveying assembly. The bending mechanism is capable of bending the pin twice.

[0014] By adopting the above technical solution, this device achieves fully automated production of "automatic assembly of the outer shell and pin → double bending of the pin" through the coordinated design of the feeding mechanism, assembly mechanism, and bending mechanism. It replaces manual operation, significantly improving production efficiency, and allows for continuous conveying, assembly, and bending without manual material changes. It precisely controls the position and angle of assembly and bending, avoiding human error and ensuring that the terminals meet the design requirements of "connecting to a specific angle."

[0015] In one embodiment, the pin delivery assembly includes a conveyor and a shearing member. The conveyor extends along its length and is capable of conveying a pin assembly, which includes a plurality of pins and a strip connecting the pins. The shearing member is capable of separating the strip from the pins.

[0016] By adopting the above technical solution, the pin conveying assembly solves the problem of continuous conveying and precise separation of pin assemblies through a "conveyor + shearing" design. The conveyor utilizes the cooperation between the material belt hole and the pin gear to ensure equidistant and stable movement of the pin assembly, preventing pin misalignment. The shearing component, through a "slot + shearing block" structure, achieves rapid separation of the material belt and the pins, resulting in uniform pin lengths after separation, meeting assembly requirements. The material belt, acting as a temporary carrier, protects the pins from deformation during conveying and reduces the complexity of conveying individual pins.

[0017] In one embodiment, the assembly mechanism includes a positioning component, a first moving component, a second moving component, and a limiting component. The positioning component is located at the end of the housing conveying component. The first moving component is located on the side of the positioning component away from the housing conveying component. The second moving component is located at the end of the pin conveying component and on one side of the width direction of the first moving component. The limiting component is located on the other side of the first moving component along the width direction. The positioning component can receive the housing delivered by the housing conveying component and deliver it into the first moving component. The limiting component can restrict the housing. The second moving component can receive the pins from the pin conveying component and insert and fix them to the housing.

[0018] By adopting the above technical solution, the positioning component ensures that the shell enters the assembly stage in the preset position, avoiding shell displacement that could lead to pin insertion failure; the first moving component drives the shell to move along the sliding groove and align with the pin conveying path, and the second moving component pushes the pin to insert into the shell, achieving precise insertion through bidirectional movement; the limiting component restricts the position of the shell to prevent it from sliding during insertion, thereby improving the stability and pass rate of the assembly.

[0019] In one embodiment, the positioning component includes a fixed plate, a first movable member, a movable plate, a movable block, and a positioning block. The fixed plate is fixed to the base. The first movable member is disposed on the fixed plate. The movable plate is fixed to the first movable member and passes through the fixed plate. The movable block is disposed on the side of the fixed plate away from the first movable member and is fixed to the movable plate. The positioning block is disposed on the fixed plate and extends into the movable block. The outer shell can enter the movable block and abut against the positioning block. The first movable member can control the movable block and the outer shell to descend and align with the first movable component.

[0020] By adopting the above technical solution, the positioning block abuts against the outer shell, thereby limiting the position of the outer shell in the length direction and ensuring that the position of the outer shell in the moving block is unique; the first moving component controls the lowering of the moving block to align with the subsequent sliding groove, avoiding the displacement of the outer shell due to height difference during the transfer process.

[0021] In one embodiment, the first moving component includes a second moving member, a sliding block, and a sliding plate. The second moving member is fixed to the base. The sliding plate and the sliding block are both disposed above the second moving member. The sliding block extends along the length direction and has a recessed sliding groove. The sliding plate extends along the length direction and passes through the sliding block. The second moving member is connected to the sliding plate, and the sliding plate can abut against the outer shell in the moving block. The second moving member can drive the sliding plate to move along the length direction, thereby causing the outer shell to move in the sliding groove.

[0022] By adopting the above technical solution, the sliding plate's retractable design allows the sliding plate to push the outer shell in only one direction. When it approaches the positioning component, the rotating plate retracts, and when it moves away, it abuts against the outer shell, preventing the outer shell from retracting and ensuring production continuity. The sliding groove is adapted to the shape of the outer shell to limit the position of the outer shell in the width direction, ensuring that the outer shell does not deviate when moving. The second moving component drives the sliding plate to move along the length direction, precisely controlling the moving distance of the outer shell and matching the height of the pin assembly position.

[0023] In one embodiment, the second movable component includes a plug plate, a third movable member, and a fourth movable member. The sliding block is also provided with a plug hole, which is close to the second movable component and communicates with the sliding groove. The plug plate can receive multiple pins. The third movable member can push the fourth movable member and the plug plate to move along the length direction. The fourth movable member can push the plug plate to move along the width direction and pass through the plug hole so that the pins are plugged and fixed to the housing.

[0024] By adopting the above technical solution, the third moving component adjusts the position of the plug plate in the length direction to align with the position of the outer shell in the sliding groove; the fourth moving component pushes the plug plate to move in the width direction so that the pin passes through the plug hole and is inserted into the outer shell, ensuring that the mating depth of the pin and the outer shell is consistent.

[0025] In one embodiment, the limiting component includes a fifth moving member and a limiting plate. The fifth moving member is fixed to the base. Two limiting plates are provided and spaced apart along the length direction. The limiting plates are fixed to the fifth moving member. The fifth moving member can control the limiting plates to move along the width direction and extend into the sliding groove and abut against both ends of the outer shell.

[0026] By adopting the above technical solution, the double limiting plates are spaced apart along the length direction and can abut against both ends of the outer shell, restricting the freedom of the outer shell in the width direction and preventing the outer shell from shifting due to the thrust of the inserted pin; the fifth moving part controls the movement of the limiting plates, making it easy for the limiting plates to flexibly exit the sliding groove or extend into the sliding groove to abut against the outer shell; the limiting plates are in rigid contact with the outer shell, and the positioning is reliable, ensuring that the insertion angle of the pin and the outer shell is perpendicular, and avoiding bending or breakage of the pin.

[0027] In one embodiment, the bending mechanism includes a first bending component and a second bending component. The first bending component is located on the side of the first moving component away from the positioning component, and the second bending component is located on the side of the first bending component away from the first moving component. The first bending component is capable of bending the pin once, and the second bending component is capable of bending the pin twice.

[0028] By adopting the above technical solution, the first and second bends are completed in steps, avoiding material deformation or breakage caused by a single bend; the two components are arranged sequentially along the length direction and are consistent with the moving path of the shell, realizing the continuity of the bending process without the need for manual transfer; the step-by-step bending allows for adjustment of angle parameters to adapt to the needs of different connection ports and offers high flexibility.

[0029] In one embodiment, the first bending assembly includes a first rotating member, a first bending plate, and a first abutting member. The first rotating member and the first bending plate are fixed and rotatable. The sliding block passes through the first rotating member. The first bending plate can abut against the pin upward and bend. The first abutting member is located at the upper end of the first rotating member and can pass through the sliding block along the height direction to abut against the outer shell.

[0030] By adopting the above technical solution, the first rotating component controls the rotation angle of the first bending plate with high precision, is reusable, and can adjust the angle so that the first bending plate abuts against the pin upwards, ensuring that the bending angle is fixed. Of course, the rotation angle of the bending plate can also be adjusted to adjust the angle of the pin. The first abutting component is fitted with a sliding block to abut against the outer shell, which is used to fix the position of the outer shell and prevent the outer shell from shifting during bending, causing the pin angle to deviate.

[0031] In one embodiment, the second bending assembly includes a second rotating member, a second bending plate, and a second abutting member. The second rotating member and the second bending plate are fixed and rotatable. The sliding block also passes through the second rotating member. The second bending plate can abut downward against the pin and bend. The second abutting member is located on one side of the second rotating member along the width direction and can abut upward at an angle against the pin.

[0032] By adopting the above technical solution, the second bending plate abuts the pin downwards; the second abutting part abuts the pin upwards at an angle, which can help fix the bending position and ensure that the pin is between the second bending plate and the second abutting part; the rotating part drives the bending plate to rotate, so as to meet the assembly requirements of the specific connection port.

[0033] In summary, this application includes at least one beneficial effect:

[0034] 1. This device, through the coordinated design of the feeding mechanism, assembly mechanism, and bending mechanism, achieves fully automated production of the entire process from "automatic assembly of the outer shell and pins → double bending of the pins." It replaces manual operation, significantly improving production efficiency. It can continuously convey, assemble, and bend without manual material changes; it precisely controls the position and angle of assembly and bending, avoiding human error and ensuring that the terminals meet the design requirements of "connecting to a specific angle."

[0035] 2. The positioning component ensures that the shell enters the assembly stage in the preset position, avoiding shell misalignment that could lead to pin insertion failure; the first moving component drives the shell to move along the sliding groove and align with the pin conveying path, and the second moving component pushes the pin to insert into the shell, achieving precise insertion through bidirectional movement; the limiting component restricts the position of the shell to prevent it from sliding during insertion, thereby improving the stability and pass rate of the assembly.

[0036] 3. The sliding plate's retractable rotating plate design allows the sliding plate to push the outer shell in only one direction: when it approaches the positioning component, the rotating plate retracts, and when it moves away, it abuts against the outer shell, preventing the outer shell from retracting and ensuring production continuity; the sliding groove is adapted to the shape of the outer shell to limit the position of the outer shell in the width direction, ensuring that the outer shell does not deviate when moving; the second moving component drives the sliding plate to move along the length direction, precisely controlling the moving distance of the outer shell and matching the height of the pin assembly position.

[0051] The following is in conjunction with the appendix Figure 1-13 The present application provides a further detailed description of the electrical connector pin bending device.

[0052] Example 1

[0053] Please see Figure 1-13 The electrical connector pin bending device provided in this application includes a base 1, a feeding mechanism 2, an assembly mechanism 3, and a bending mechanism 4.

[0054] like Figures 1 to 4As shown, the feeding mechanism 2 includes a housing conveying assembly 21 and a pin conveying assembly 22. Specifically, the housing conveying assembly 21 is located at one end of the base 1 along its length and may include a chute. The housings 6 can sequentially enter the chute and slide to the end for subsequent assembly processing. The pin conveying assembly 22 is located on the base 1 and includes a conveying component 221 and a shearing component 222. The conveying component 221 extends along its length and can convey the pin assembly 5. The pin assembly 5 includes multiple pins 51 and a material strip 52 connecting the pins 51. In this embodiment, the conveying component 221 may be a transmission mechanism with a pinion gear. The pinion gear has multiple protrusions, and the material strip 52 has multiple holes. The protrusions of the pinion gear cooperate with the holes on the material strip 52. When the pinion gear rotates, it can drive the pin assembly 5 to move. The shearing component 222 can cut the material strip 52. It includes a slot 2221 located below the material strip 52 and a shearing block 2222 above the material strip 52. The conveying component 221 places the material strip 52 of appropriate length onto the slot 2221. Then, the shearing block 2222, driven by a power device such as a cylinder, pushes the material strip 52 into the slot, thereby separating the pin 51 from the material strip 52 and ensuring that multiple pins 51 can be received by the subsequent assembly mechanism 3. This arrangement of the feeding mechanism 2 allows the housing 6 and the pins 51 to be transported to the assembly mechanism 3 in an orderly and efficient manner. The housing conveying assembly 21 and the pin conveying assembly 22 have clear division of labor and each plays its role. They separate the pins 51 from the material strip 52 through the shearing component 222, preparing for the subsequent assembly work.

[0055] like Figures 5 to 6 As shown, the assembly mechanism 3 is located on the base 1 and on one side of the outer casing conveying assembly 21 along its length. Specifically, it includes a positioning assembly 31, a first moving assembly 32, a second moving assembly 33, and a limiting assembly 34. In this embodiment, the positioning assembly 31 includes a fixed plate 311, a first moving member 312, a moving plate 313, a moving block 314, and a positioning block 315. The fixed plate 311 is fixed to the base 1, serving to support the entire positioning assembly 31. The first moving member 312 is located on the fixed plate 311 and can be an electric push rod or a hydraulic push rod, providing power for movement along the height direction. The moving plate 313 passes through the fixed plate 311 and is fixed to the first moving member 312. The moving block 314 is fixed to the moving plate 313 and has a limiting groove 3141 recessed inside. The positioning block 315 is located on the fixed plate 311 and extends downward into the limiting groove 3141 of the moving block 314. The outer casing 6 enters the limiting groove 3141 from the outer casing conveying assembly 21, and then the other end abuts against the positioning block 315, which can ensure the accurate position of the outer casing 6. Subsequently, the first moving member 312 can control the moving plate 313, the moving block 314 and the outer casing 6 to descend a fixed distance and align with the subsequent first moving assembly 32.

[0056] like Figures 7 to 9As shown, the first moving component 32 includes a second moving member 321, a sliding block 322, and a sliding plate 323. Specifically, the second moving member 321 is fixed to the base 1, and it can also be driven by an electric push rod or a servo motor to drive a lead screw. The sliding plate 323 and the sliding block 322 are both located above the second moving member 321. The sliding block 322 extends along the length direction and has a recessed sliding groove 3221. The sliding plate 323 extends along the length direction and passes through the sliding block 322. The second moving member 321 is connected to the sliding plate 323 and can control the movement of the sliding plate 323 to abut against the outer shell 6 in the moving block 314. In this embodiment, the sliding plate 323 is provided with a plurality of rotating plates 3231 spaced apart along the length direction. The rotating plates 3231 can extend and retract on the sliding plate 323. When the second moving member 321 moves the sliding plate 323 along the direction close to the positioning component 31, the rotating plate 3231 abuts against the outer shell 6 and retracts into the sliding plate 323. When the sliding plate 323 moves along the direction away from the positioning component 31, the rotating plate 3231 abuts against the outer shell 6 and carries the outer shell 6 into the sliding groove 3221 and moves in the sliding groove 3221. Therefore, by the second moving member 321 moving the sliding plate 323 back and forth along the length direction, multiple outer shells 6 can move in the sliding groove 3221.

[0057] like Figures 10 to 11 As shown, the second moving component 33 includes a plug-in plate 331, a third moving member 332, and a fourth moving member 333. In this embodiment, the sliding block 322 is also provided with a plug-in hole 3222, which is close to the second moving component 33 and communicates with the sliding groove 3221. The plug-in plate 331 can receive multiple pins 51. The third moving member 332 can push the fourth moving member 333 and the plug-in plate 331 to move along the length direction, and the fourth moving member 333 can push the plug-in plate 331 to move along the width direction. After the pins 51 are separated from the strip 52, the fourth moving member 333 pushes the plug-in plate 331 to receive the pins 51. Then, the fourth moving member 333 retracts, and the third moving member 332 first pushes it to a suitable position. Then, the fourth moving member 333 pushes the plug-in plate 331 to move along the width direction and pass through the plug-in hole 3222, so that the pins 51 are plugged into and fixed with the housing 6 to form a terminal. Both the third moving part 332 and the fourth moving part 333 can be telescopic cylinders.

[0058] like Figure 12As shown, the limiting component 34 includes a fifth moving part 341 and a limiting plate 342. Specifically, the fifth moving part 341 is fixed to the base 1, and two limiting plates 342 are provided and spaced apart along the length direction. The limiting plates 342 are fixed to the fifth moving part 341. The fifth moving part 341 can control the limiting plate 342 to move along the width direction, thereby extending into the sliding groove 3221 and abutting against both ends of the outer shell 6, thus limiting the position of the outer shell 6 and ensuring accurate insertion of the pin 51 into the outer shell 6. The various components of the assembly mechanism 3 cooperate with each other. The positioning component 31 ensures that the outer shell 6 is accurately positioned, the first moving component 32 moves the outer shell 6 to the appropriate position, the second moving component 33 realizes the insertion of the pin 51 into the outer shell 6, and the limiting component 34 ensures the stability of the outer shell 6 during the insertion process. They work together to improve the assembly accuracy and efficiency of the pin 51 and the outer shell 6.

[0059] like Figure 13As shown, the bending mechanism 4 is located on the base 1 and on the side of the assembly mechanism 3 away from the outer shell conveying assembly 21. Specifically, it includes a first bending assembly 41 and a second bending assembly 42. The first bending assembly 41 includes a first rotating member 411, a first bending plate 412, and a first abutting member 413. The first rotating member 411 and the first bending plate 412 are fixed and rotatable, and a sliding block 322 passes through the first rotating member 411. In this embodiment, the first rotating member 411 can be a transmission mechanism composed of a telescopic cylinder, a rack, and a gear. The sliding block 322 passes through the gear, and the telescopic cylinder moves the rack along the width direction. The rack meshes with the gear, thereby causing the gear to drive the first bending plate 412 to rotate at a certain angle. The first bending plate 412 abuts against the insert pin 51 upwards and bends it. The first abutting member 413 is located at the upper end of the first rotating member 411 and can pass through the sliding block 322 along the height direction to abut against the outer shell 6, playing the role of fixing the outer shell 6 during the bending process. The second bending assembly 42 includes a second rotating member 421, a second bending plate 422, and a second abutting member 423. The second rotating member 421 and the second bending plate 422 are fixed but rotatable. The second rotating member 421 has the same structure as the first rotating member 411, and a gear passes through the sliding block 322 in the second rotating member 421. The second bending plate 422 can abut downwards against the pin 51 and bend it. The second abutting member 423 is located on one side of the second rotating member 421 along its width direction and can abut upwards at the pin 51, ensuring that the pin 51 is located between the second bending plate 422 and the second abutting member 423. This ensures that during the secondary bending process, the pin 51 can be bent by the second bending plate 422 until it abuts against the second abutting member 423. Through the cooperation of the first bending assembly 41 and the second bending assembly 42, the bending mechanism 4 achieves two bends of the pin 51, enabling the pin 51 to meet the requirements of a specific connection angle. The first abutment 413 and the second abutment 423 ensure the stability of the outer shell 6 and the pin 51 during bending, and improve the bending accuracy. Both the first abutment 413 and the second abutment 423 may include a telescopic motor and an abutment plate. The telescopic motor drives the abutment plate to abut against the outer shell or the pin, so as to ensure that the pin can be bent stably.

[0060] The coordinated operation of this device is controlled by a central control system, such as a PLC or industrial computer. This PLC is connected to multiple sensors, including a photoelectric sensor at the end of the housing conveyor assembly 21, a limit switch to detect when the moving block 314 has descended to its designated position, and an angle sensor to confirm the completion of bending. Based on the signals input from each sensor, the PLC sequentially outputs control signals to each moving and rotating component according to a preset program logic, thereby precisely controlling the timing and stroke of a series of actions such as feeding, positioning, assembly, bending, and retrieving, achieving full-process automation.

[0061] The connector pin bending device also includes a receiving component 7, which is located on the side of the bending assembly away from the first moving component 32. The rotating plate 3231 on the sliding plate 323 can push the terminal after secondary bending into the receiving component 7 for recycling under the action of the second moving component 321, facilitating subsequent processing. In this embodiment, the receiving component 7 includes an inclined chute and a receiving plate. The terminal falls into the receiving plate through the chute for easy subsequent collection.

[0062] The implementation principle of this embodiment is as follows: The outer shell 6 is sequentially conveyed by the outer shell conveying assembly 21. When the outer shell 6 enters the limiting groove 3141 of the moving block 314 and abuts against the positioning block 315, the photoelectric sensor triggers a signal to the PLC. After receiving the positioning signal, the PLC controls the first moving component 312 to start, driving the moving block 314 and the outer shell 6 to descend to a predetermined height, and the limit switch confirms that it is in place. Subsequently, the second moving component 321 starts, driving the sliding plate 323 to move the outer shell 6 horizontally to the assembly station. The limiting plate 342 of the limiting assembly 34 then extends into the sliding groove 3221 to fix the position of the outer shell 6. At the same time, the pin assembly 5 is driven by the conveying component 221 and the pins 51 are separated by the shearing component 222. Then, the PLC sequentially activates the third moving part 332 and the fourth moving part 333. First, the fourth moving part 333 controls the plug plate 331 to collect the pin 51. Then, the third moving part 332 pushes the plug plate 331 along the length direction to the plug hole 3222 position, and the fourth moving part 333 pushes the plug plate 331 along the width direction to complete the assembly of the pin 51 and the housing 6, forming a terminal. Subsequently, under the action of the second moving part 321, the terminal enters the bending mechanism 4 and the first bending assembly 41 is activated. The first abutting part 413 first abuts against the housing 6, and then the first rotating part 411 drives the first bending plate 412 to rotate upward, completing the first bending of the pin 51. The terminal continues to move to the second bending assembly 42, where the second abutting part 423 abuts against the lower end of the pin 51, and the second bending plate 422 abuts against the pin 51 downward to complete the second bending. Finally, the bent terminal is pushed into the receiving part 7 by the rotating plate 3231 on the sliding plate 323. Compared with traditional manual assembly and single bending methods, this device greatly improves the accuracy and efficiency of pin assembly and bending, resulting in more stable product quality. It can adapt to connectors with specific connection angles, meeting the needs of some special application scenarios and making significant improvements and contributions to existing technologies.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
