[0002] The wire rod assembly comprises a terminal and a wire connected to the terminal, and the terminal serves as a connecting piece to facilitate the connection of the wire with other devices or circuit boards, and is widely used in electronic devices. In the electronic devices, the space is usually limited, and the wire of the wire rod assembly is usually bent to adapt to the space layout of the device.

[0003] At present, the bending of the wire rod assembly is usually achieved by holding the wire with one hand and operating the clamp with the other hand to clamp and rotate the wire by a certain angle, thereby realizing the bending of the wire. However, the manual operation results in low production efficiency and is not conducive to improving the automation efficiency. UTILITY MODEL CONTENT

[0004] The main purpose of the utility model is to provide a wire rod bending mechanism and wire rod forming equipment, which realizes the automatic bending of the wire and improves the automation efficiency.

[0005] To achieve the above purpose, the wire rod bending mechanism comprises a jig, a rotary drive assembly and a first clamping assembly, the jig is used for clamping the wire, the rotary drive assembly and the jig are arranged at intervals and have a first rotary shaft that can rotate around the vertical direction, the first clamping assembly comprises a clamping drive member and two first clamping members connected to the clamping drive member, the clamping drive member is connected to the first rotary shaft, and the two first clamping members are driven by the clamping drive member to open and close along the horizontal direction to clamp the part of the wire that is not clamped by the jig, and the rotary shaft drives the two first clamping members to bend the wire in the horizontal plane.

[0006] In an embodiment, the opposite parts of the two clamping members are respectively concave to form guide grooves, and the two guide grooves are used for clamping the opposite sides of the wire.

[0007] In an embodiment, the size of the groove of the guide groove decreases from the opening to the bottom wall.

[0008] In an embodiment, the guide groove is formed by the first clamping member extending along the circumference.

[0009] In one embodiment, the rotary drive assembly includes a rotary drive member, a drive wheel, and a driven wheel. The rotary drive member and the fixture are spaced apart and are provided with a first rotary shaft. The drive wheel is sleeved on the first rotary shaft to rotate. The driven wheel is arranged perpendicular to the vertical direction and spaced apart from the drive wheel, and is drively connected to the drive wheel. The clamping drive member is connected to the driven wheel to rotate.

[0010] In one embodiment, the wire bending mechanism further includes a lifting drive assembly, which is spaced apart from the fixture, and the rotary drive assembly is tractively connected to the lifting drive assembly to bend the wire in a vertical direction.

[0011] In one embodiment, the lifting drive assembly includes a lifting mounting base, a lifting drive component, a lifting guide rail, and a lifting slider. The lifting drive component and the fixture are spaced apart. The lifting drive component is connected to the lifting mounting base. The lifting guide rail is connected to the side of the lifting mounting base facing the rotary drive assembly. The lifting slider is connected to the rotary drive assembly and slidably connected to the lifting guide rail, so that the rotary drive assembly moves up and down along the extension direction of the lifting guide rail under the drive of the lifting drive component.

[0012] In one embodiment, the lifting drive assembly further includes a plurality of stroke sensors, which are spaced apart on the lifting mounting base along the lifting direction of the rotary drive assembly to detect the lifting stroke of the rotary drive assembly. And / or, the wire bending mechanism further includes a horizontal drive module, which is spaced apart from the fixture, and the lifting drive assembly is driveably connected to the horizontal drive module for translation in the horizontal direction.

[0013] In one embodiment, the fixture includes a support base and a plurality of second clamping assemblies, which are spaced apart along the same axial direction on the support base to clamp various portions of the conductor along the axial direction.

[0014] This utility model also proposes a wire forming device, which includes a first forming device and a second forming device. The first forming device is used to bend a first portion of the wire to form a first bent portion of the wire. The second forming device and the first forming device are arranged at intervals and include the wire bending mechanism as described above. The wire bending mechanism is used to bend a second portion of the wire to form a second bent portion of the wire.

[0015] In the initial state of this invention, the fixture clamps the wire, and the portion of the wire to be bent is in a straight line. Then, the clamping drive unit drives two first clamping members to horizontally clamp the wire. Driven by the rotation of the rotary drive assembly's rotating shaft, the portion of the wire clamped by the two first clamping members bends relative to the portion clamped by the fixture. The rotation angle can be precisely set by controlling the rotary drive assembly to ensure consistent bending angles each time. Once the predetermined bending angle is reached, the rotary drive assembly stops, and the first clamping members release the wire. The fixture also opens, completing one bending operation. Therefore, this invention can achieve automated wire bending, resulting in higher production efficiency and improved automation efficiency.

[0016] It is worth noting that, because the wire is held horizontally, when it bends vertically, the direction of the clamping force and the bending angle of the wire are on the same plane, which allows the wire to have a better bending shape and helps to further improve the forming quality of the wire.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] A wire assembly includes terminals and wires connected to the terminals. The terminals act as connectors, allowing the wires to be easily connected to other devices or circuit boards, and are widely used in electronic devices. However, within electronic devices, space is often limited, necessitating the bending of the wires in the wire assembly to adapt to the device's spatial layout.

[0034] Currently, bending wire assemblies mostly involves an operator holding the wire with one hand and using a clamp to hold and rotate it at a certain angle to achieve the bend. However, this manual operation results in low production efficiency and hinders the improvement of automation efficiency.

[0035] To address the aforementioned issues, this invention proposes a wire bending mechanism 10, which aims to automate the bending of the conductor 933 to improve automation efficiency.

[0036] Reference Figures 1 to 10In one embodiment of this utility model, the wire bending mechanism 10 includes a fixture 1, a rotary drive assembly 4, and a first clamping assembly 5. The fixture 1 is used to clamp the wire 933. The rotary drive assembly 4 and the fixture 1 are spaced apart and have a first rotating shaft 411 that can rotate around the vertical direction. The first clamping assembly 5 includes a clamping drive member 51 and two first clamping members 53 driven to the clamping drive member 51. The clamping drive member 51 is connected to the first rotating shaft 411. The two first clamping members 53 open and close in the horizontal direction under the drive of the clamping drive member 51 to clamp the part of the wire 933 that is not clamped by the fixture 1. The rotating shaft 411 drives the two first clamping members 53 to bend the wire 933 in the horizontal plane.

[0037] in, Figure 9 A structural diagram of an embodiment of a wire assembly is provided. The wire assembly may include a terminal 931 and two wires 933 connected to the terminal 931. The two wires 933 are joined together by a sleeve body 935, and then the first bending portion 9331 is bent by a wire bending mechanism 10.

[0038] In the initial state of this invention, the fixture 1 clamps the wire 933, and the portion of the wire 933 to be bent is in a straight line. Then, the clamping drive 51 drives the two first clamping members 53 to horizontally clamp the wire 933. Driven by the rotation of the rotating shaft 411 of the rotating drive assembly 4, the portion of the wire 933 clamped by the two first clamping members 53 is bent relative to the portion clamped by the fixture 1. The rotation angle can be precisely set by controlling the rotating drive assembly 4 to ensure that the bending angle is consistent each time. When the predetermined bending angle is reached, the rotating drive assembly 4 stops, and the first clamping assembly 5 releases the wire 933. The fixture 1 also opens, completing one bending action. Therefore, this invention can achieve automated bending of the wire 933, resulting in high production efficiency and improving automation efficiency.

[0039] It is worth noting that, due to the horizontal clamping method, when the wire 933 is bent in the vertical direction, the direction of the clamping force and the bending angle of the wire 933 are on the same plane, which allows the wire 933 to have a better bending shape, which is beneficial to further improve the forming quality of the wire 933.

[0040] Reference Figure 4 In one embodiment of the present invention, the opposing portions of the two first clamping members 53 are respectively provided with guide grooves 5311, and the two guide grooves 5311 are used to hold the wire 933 on opposite sides.

[0041] In this embodiment, the design of the guide groove 5311 can be customized according to customer needs, ensuring that the wire 933 is bent according to the predetermined arc, thereby improving the consistency and accuracy of the finished product. Furthermore, the recessed design of the guide groove 5311 can reduce the pressure on the wire 933 during bending, preventing damage to the wire 933.

[0042] Specifically, each of the two first clamping members 53 has a first clamping jaw 531, and each of the two first clamping jaws 531 has a guide groove 5311. Clamping is achieved by opening and closing the two first clamping jaws 531.

[0043] Reference Figure 4 In one embodiment of the present invention, the groove size of the guide groove 5311 is reduced along the direction from the opening to the bottom wall.

[0044] In this embodiment, the tapered slot design makes it easier for the wire 933 to enter the slot, and the clamping force gradually increases as the clamping member closes, thereby ensuring that the wire 933 will not slip during bending. In addition, since the slot is wider at the opening and gradually narrows after entering the slot, the direct pressure on the surface of the wire 933 can be reduced, avoiding damage to the wire 933 during clamping.

[0045] Reference Figure 4 In one embodiment of the present invention, the guide groove 5311 is formed by the first clamping member 53 extending circumferentially.

[0046] In this embodiment, the circumferentially extending guide groove 5311 provides a larger contact area, ensuring good clamping of the wire 933 at any angle and increasing clamping stability. Furthermore, the circumferential distribution of the guide groove 5311 evenly distributes the clamping force across different parts of the wire 933, reducing damage to the wire 933 caused by excessive localized force.

[0047] Reference Figure 3 In one embodiment of this utility model, the rotary drive assembly 4 includes a rotary drive member 41, a drive wheel 451, and a driven wheel 453. The rotary drive member 41 and the fixture 1 are spaced apart and are provided with a first rotary shaft 411. The drive wheel 451 is sleeved on the first rotary shaft 411 to rotate. The driven wheel 453 is arranged perpendicular to the vertical direction and spaced apart from the drive wheel 451, and is drively connected to the drive wheel 451. The clamping drive member 51 is connected to the driven wheel 453 to rotate.

[0048] In this embodiment, the power of the rotary drive 41 can be effectively transmitted to the clamping drive 51 through the gear transmission of the driving wheel 451 and the driven wheel 453, achieving precise rotation control. Furthermore, the rotary drive 41 and the fixture 1 are spaced apart, making the overall layout of the mechanism more rational and saving space. In addition, the gear transmission method is relatively simple, facilitating daily maintenance and repair.

[0049] Optionally, the rotary drive 41 includes a drive motor and a rotary sensor. The drive motor has a rotary shaft 411 and precisely controls the overall rotation of the first clamping assembly 5. The rotary sensor can also detect the rotational position of the rotary shaft 411 to further improve the stability of the device.

[0050] Reference Figure 2 In one embodiment of the present invention, the wire bending mechanism 10 further includes a lifting drive component 3, the lifting drive component 3 and the fixture 1 are spaced apart, and the rotation drive component 4 is connected to the lifting drive component 3 to bend the wire 933 in the vertical direction.

[0051] In this embodiment, the lifting drive component 3 enables the wire 933 to bend vertically, increasing the bending dimension and allowing for the processing of wires with complex shapes. Furthermore, the vertical movement makes the entire bending process more flexible, adapting to more diverse processing needs.

[0052] Reference Figure 2 and Figure 3 In one embodiment of this utility model, the lifting drive assembly 3 includes a lifting mounting base 31, a lifting drive component 33, a lifting guide rail 35, and a lifting slider 37. The lifting drive component 33 and the fixture 1 are spaced apart. The lifting drive component 33 is connected to the lifting mounting base 31. The lifting guide rail 35 is connected to the side of the lifting mounting base 31 facing the rotary drive assembly 4. The lifting slider 37 is connected to the rotary drive assembly 4 and slidably connected to the lifting guide rail 35, so that the rotary drive assembly 4 moves up and down along the extension direction of the lifting guide rail 35 under the drive of the lifting drive component 33.

[0053] In this embodiment, the cooperation between the lifting guide rail 35 and the lifting slider 37 ensures the stability of the rotary drive assembly 4 during the lifting process. Furthermore, the lifting drive component 33 can precisely control the lifting height, thereby precisely controlling the bending position of the guide wire 933, achieving automated lifting action, and thus improving production efficiency.

[0054] Reference Figure 2 and Figure 3In one embodiment of this utility model, the lifting drive assembly 3 further includes a plurality of stroke sensors 38, which are arranged at intervals on the lifting mounting base 31 along the lifting direction of the rotary drive assembly 4 to detect the lifting stroke of the rotary drive assembly 4. And / or, the wire bending mechanism 10 further includes a horizontal drive module 2, which is spaced apart from the fixture 1, and the lifting drive assembly 3 is tractively connected to the horizontal drive module 2 to perform translation in the horizontal direction.

[0055] In this embodiment, multiple stroke sensors 38 can monitor the vertical position of the rotary drive assembly 4 in real time, ensuring precise control of the bending position of the guide wire 933. Furthermore, the stroke sensors 38 can detect extreme positions to prevent mechanical damage caused by overload or misoperation. Real-time monitoring allows for timely detection and correction of deviations, improving the safety and reliability of the system.

[0056] Optionally, the horizontal drive module 2 may include a first translation component 21 and a second translation component 23. Through the cooperation of the first translation component 21 and the second translation component 23, the position of the lifting drive component 3 can be adjusted in the horizontal direction. Combined with the vertical lifting adjustment, the position of the wire 933 can be precisely adjusted in three-dimensional space, which enhances the operational flexibility of the equipment and enables it to handle wires 933 at different heights and positions.

[0057] Reference Figure 5 and Figure 6 In one embodiment of the present invention, the fixture 1 includes a support base 11 and a plurality of second clamping components 13. The plurality of second clamping components 13 are arranged at intervals along the same axial direction on the support base 11 to clamp the various parts of the conductor 933 along the axial direction.

[0058] In this embodiment, multiple second clamping components 13 can simultaneously fix different parts of the wire 933, ensuring that the wire 933 remains stable during bending. This reduces the risk of the wire 933 shifting during bending and improves the bending accuracy. Furthermore, when a specific segment of the wire 933 needs to be bent, the corresponding second clamping component 13 can be opened for clamping and bending by the first clamping component 5, thus facilitating the multi-segment bending of the wire 933.

[0059] Reference Figures 5 to 7In one embodiment of the present invention, a storage hole 111 is vertically provided on one surface of the support base 11, and a telescopic hole 1111 is respectively recessed on the opposite side walls of the storage hole 111. The second clamping assembly 13 includes a second clamping member 131 and a third clamping member 133. The second clamping member 131 is movably disposed along the depth direction of one of the telescopic holes 1111, and the third clamping member 133 is movably disposed along the depth direction of the other telescopic hole 1111, so that the second clamping member 131 and the third clamping member 133 can move toward each other or away to clamp or release the wire 933.

[0060] In this embodiment, the design of the storage hole 111 allows the second clamping member 131 and the third clamping member 133 to partially extend into the storage hole 111 and slide along the depth of the telescopic hole 1111. Furthermore, through the design of the telescopic hole 1111, the second clamping member 131 and the third clamping member 133 can automatically align with different parts of the wire 933, simplifying the operation process.

[0061] Optionally, a spring is arranged within each telescopic hole 1111. One end of the spring is connected to the inner wall of the telescopic hole 1111, and the other end is connected to the second clamping member 131 or the third clamping member 133. The constant pressure provided by the spring ensures stable clamping force between the second clamping member 131 and the third clamping member 133, reducing the risk of damage or slippage of the wire 933 due to insufficient clamping force or over-clamping. Furthermore, the spring helps the second clamping member 131 and the third clamping member 133 to automatically reset, reducing the time required for manual adjustment by the operator and simplifying the operation process.

[0062] In another embodiment, one of the second and third clamping members remains stationary while the other moves toward or away from each other to clamp the wire 933.

[0063] Reference Figure 6 and Figure 8 In one embodiment of the present invention, the fixture 1 further includes a clamp release assembly 80, which includes a clamp release drive assembly 83 and a clamp release member 81. The clamp release drive assembly 83 and the fixture 1 are spaced apart. The clamp release member 81 is located at the output end of the clamp release drive assembly 83 and is movably abutted against the second clamping member 131 and the third clamping member 133, thereby driving the second clamping member 131 and the third clamping member 133 to move in a direction away from each other.

[0064] In this embodiment, the clamp release drive assembly 83 drives the second clamping member 131 and the third clamping member 133 to move away from each other via the clamp release member 81, thereby realizing the automatic clamp release function. Therefore, the need for manual intervention is reduced, and the second clamping member 131 and the third clamping member 133 move quickly when releasing the wire 933, thus improving the production speed.

[0065] Optionally, the loosening clamp 81 includes two loosening clamp blocks 811 and a loosening clamp drive assembly 83. The loosening clamp drive assembly 83 includes a loosening clamp cylinder 831 and a lifting cylinder 833, etc. The two loosening clamp blocks 811 can be kept open or closed under the drive of the loosening clamp cylinder 831, and the movement of the two loosening clamp blocks 811 is driven by the lifting cylinder 833 and other drive components. Furthermore, the movement of the second clamping member 131 and the third clamping member 133 can be achieved through the transmission hole 113, so that the second clamping member 131 and the third clamping member 133 move in a direction away from each other, thereby loosening the jig 1. In order to reduce the contact friction between the second clamping member 131 and the third clamping member 133 and the two loosening clamp blocks 811, the second clamping member 131 and the third clamping member 133 are also respectively provided with rollers 1311 for rolling contact.

[0066] It is worth noting that this utility model does not specifically limit the clamping method of the fixture 1. Any technical solution that uses the clamping drive component 83 to drive the clamping component 81 to move in order to achieve the clamping of the fixture 1 falls within the protection scope of this utility model.

[0067] This utility model also proposes a wire forming device 1000, which includes a first forming device 600 and a second forming device 100. The first forming device 600 is used to bend a first portion of a conductor 933 so that the conductor 933 forms a first bent portion 9331. The second forming device 100 and the first forming device 600 are arranged at intervals and include a wire bending mechanism 10 as described above. The wire bending mechanism 10 is used to bend a second portion of the conductor 933 so that the conductor 933 forms a second bent portion 9333.

[0068] Since the wire bending mechanism 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. In addition, the first forming device 600 and the second forming device 100 may each include a heating component 70. The heating component 70 includes a main body 73, a heating tube 73, and a third translation component 71, etc., for adjusting the air outlet position of the heating tube 73, so as to heat the bent wire 933, thereby realizing further thermoforming.

[0069] In the technical solution of this utility model, by using the first forming device 600 and the second forming device 100 to process different parts of the wire 933 respectively, multi-segment bending of the wire 933 can be achieved, forming a more complex shape. In addition, each forming device is independently controlled, which can achieve precise control of different parts of the wire 933 and improve bending accuracy.

[0070] For example, refer to Figure 9 The wire assembly includes connected terminals 931 and two conductors 933 passing through an insulating tube 935. It is sequentially processed according to the number of bends, their positions, and shapes to form the following structural states: an initial wire assembly 90, a wire assembly 91 after the first bend, a wire assembly 92 after the second bend, and a wire assembly 93 after the third bend. Specifically, the conductors 933 are bent and heated by a first forming device 600 to form the first bent portion 9331, and the conductors 933 are bent and heated by a second forming device 100 to form the second bent portion 9333. Since the bending positions and shapes of the first and second bent portions differ—the first bent portion is located near the terminal 931, and the second bent portion is located in the middle of the conductor 933—the bending mechanisms of the first forming device 600 and the second forming device 100 can be two different mechanisms. It is worth noting that the composition of the forming device is not specifically limited. Any bending and forming of the wire 933 of the wire assembly by multiple forming devices falls within the protection scope of this utility model.

[0071] Optionally, the wire forming equipment 1000 further includes a third forming device, which is used to bend and heat the conductor 933 of the wire assembly to form a third bend 9335 on the conductor 933, thereby achieving a tail bend on the side of the conductor 933 away from the terminal 931. Since the composition of the third forming device is the same as that of the second forming device 100, it will not be described in detail here.

[0072] Optionally, the wire forming equipment 1000 also includes a turntable 16, on which the fixture 1 is mounted. The turntable 16 enables the switching between the first forming device 600 and the second forming device 100, which helps to further reduce the overall volume of the wire forming equipment 1000.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
