[0006] Optionally, the torsion mechanism further includes a support frame, and the conveying assembly includes a feeding vibratory plate and a first conveying member. The feeding vibratory plate and the first torsion assembly are spaced apart from each other on the support frame along a second direction. The first conveying member is movably connected to the support frame, and the workpiece on the feeding vibratory plate is conveyed to the first torsion assembly through the first conveying member; wherein, the first direction is perpendicular to the second direction.

[0007] Optionally, the conveying assembly further includes a linear vibratory feeder and a second conveyor. The feeding vibratory plate, the linear vibratory feeder, the second conveyor, and the first torsional assembly are arranged sequentially along the second direction. The workpiece on the feeding vibratory plate is conveyed to the second conveyor via the linear vibratory feeder. The second conveyor can convey the workpiece on it along a third direction to the gripping station. The workpiece at the gripping station is conveyed to the first torsional assembly via the first conveyor. The first direction, the second direction, and the third direction are perpendicular to each other.

[0008] Optionally, the second conveying member includes a first driving member and a moving block, the moving block being connected to the output end of the first driving member, and the first driving member being used to drive the moving block to reciprocate along the third direction; The moving block has a receiving groove on the side facing the linear vibrating feeder. The feeding groove of the linear vibrating feeder passes through the linear vibrating feeder along the second direction. The receiving groove can connect with the feeding groove of the linear vibrating feeder.

[0009] Optionally, the first conveying member includes a gripping member, a first connecting seat, a second connecting seat, a second driving member, a third driving member, and a fourth driving member. The second driving member is disposed on the support frame. The first connecting seat is connected to the output end of the second driving member. The second driving member is used to drive the first connecting seat to reciprocate along the second direction. The third driving member and the second connecting seat are disposed on the first connecting seat, the second connecting seat is connected to the output end of the third driving member, and the third driving member is used to drive the second connecting seat to reciprocate along a third direction; The fourth driving member is disposed on the second connecting seat, and the gripper is connected to the output end of the fourth driving member. The fourth driving member is used to drive the gripper to reciprocate along the first direction; wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0010] Optionally, the support frame is provided with a feeding structure. Along the second direction, the first torsion assembly is located between the feeding vibratory plate and the feeding structure. The workpiece processed by the first torsion assembly and the second torsion assembly is conveyed to the feeding structure through the gripper.

[0011] Optionally, the gripper includes a first sub-gripper and a second sub-gripper, which are spaced apart along the second direction, and both the first and second sub-grippers are connected to the output end of the fourth drive unit.

[0012] Optionally, the torsion mechanism further includes a fifth driving member, the second torsion component is connected to the output end of the fifth driving member, and the fifth driving member is used to drive the second torsion component to reciprocate along the first direction so that the second torsion component moves closer to or further away from the first torsion component.

The second gripper is connected to the output end of the seventh drive member, and the seventh drive member applies torque along the second torsion direction to the second end through the second gripper.

[0014] According to the torsion mechanism provided in this embodiment of the utility model, the conveying component transports the workpiece (e.g., a national standard charging socket spring-type terminal) to the working position of the first torsion component according to a preset path, realizing precise loading and positioning of the workpiece. Since the first torsion component and the second torsion component are arranged opposite to each other along a first direction, when the workpiece arrives at the first torsion component, the first torsion component clamps the first end of the workpiece and applies a torque along the first torsion direction (e.g., clockwise) to that end. At the same time, the second torsion component simultaneously clamps the second end of the workpiece and applies a torque in the second torsion direction (e.g., counterclockwise) opposite to the first torsion direction to that end. Under the combined action of the two opposing torques, the workpiece is torsioned to form the required torsion spring structure. After the torsion processing is completed, the first torsion component and the second torsion component release the workpiece so that the processed workpiece can be transferred later. By automatically conveying the workpiece through the conveying component, replacing manual loading, and simultaneously applying opposing torques to both ends of the workpiece by the first torsion component and the second torsion component to complete the torsion, the manual operation links are greatly reduced, effectively solving the problem of low efficiency of manual operation, and significantly improving the production efficiency of national standard charging socket spring-type terminals, adapting to the needs of mass production. In addition, the first and second torsion components precisely clamp the two ends of the workpiece through mechanical structure and apply controllable reverse torque, avoiding the problem of workpiece misalignment caused by uneven force control and torsion angle deviation during manual operation. This ensures the processing accuracy of the torsion spring structure, thereby ensuring that the insertion and extraction force of the finished torsion spring terminals meets the usage standards, reducing the defect rate, and reducing direct manual involvement in the torsion operation, thus reducing the labor intensity of operators.

Detailed Implementation

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 8 As shown, one embodiment of the present invention provides a torsion mechanism, including a conveying component 1, a first torsion component 2, and a second torsion component 3; The first torsion assembly 2 and the second torsion assembly 3 are arranged opposite to each other along the first direction, and the conveying assembly 1 is used to convey the workpiece 10 to the first torsion assembly 2; The first torsion assembly 2 is used to clamp the first end of the workpiece 10 and is capable of applying torque to the first end in the first torsion direction; The second torsion assembly 3 is used to clamp the second end of the workpiece 10 and can apply torque to the second end in a second torsion direction; the first torsion direction is opposite to the second torsion direction. The first end and the second end are the two ends of the workpiece 10 opposite to each other in the first direction. The first torsion assembly 2 and the second torsion assembly 3 are arranged opposite each other in the first direction. When the workpiece 10 is conveyed to the working position of the first torsion assembly 2 by the conveying assembly 1, the two torsion assemblies clamp the two ends of the workpiece 10 simultaneously. The first torsion assembly 2 applies torque in the first torsion direction to the first end of the workpiece 10, and the second torsion assembly 3 simultaneously applies torque in the second torsion direction opposite to the first torsion direction to the second end of the workpiece 10. This synchronous reverse force application method enables the workpiece 10 to achieve uniform and precise torsion under double-head clamping, avoiding the problem of misalignment caused by single-hand torsion in manual operation. Since the torque of the two torsion assemblies is applied synchronously, the torsion process of the workpiece 10 is more stable and the torsion angle is more accurate, thereby ensuring the processing accuracy and product quality consistency of the torsion spring structure, and making the insertion and extraction force of the finished torsion spring terminals fully meet the usage standards. The first direction refers to the direction in which the first torsion assembly 2 and the second torsion assembly 3 are arranged relative to each other, that is, the axial direction of the workpiece 10 (from one end to the other). In this embodiment, the first direction is the attached... Figure 1 The Z-direction. The first torsion direction refers to the torsion direction applied by the first torsion component 2 to the first end of the workpiece 10 (e.g., clockwise). The second torsion direction refers to the torsion direction applied by the second torsion component 3 to the second end of the workpiece 10 (e.g., counterclockwise), which is opposite to the first torsion direction. Through the automated double-headed opposing torsion design, the drawbacks of manual operation are fundamentally overcome. It greatly improves processing efficiency and realizes continuous and automated production, far exceeding the speed of manual operation; at the same time, it ensures extremely high product quality consistency. Because the two torsion components apply reverse torque to both ends of the workpiece 10 precisely and synchronously, it ensures that the torsion axis always coincides with the theoretical axis of the workpiece 10, thus perfectly solving the problem of poor insertion and extraction force caused by "torsion misalignment", and significantly improving the reliability and yield of products such as national standard charging socket springs.

[0023] In one embodiment, the torsion mechanism further includes a support frame 4, and the conveying assembly 1 includes a feeding vibratory feeder 11 and a first conveying member 12. The feeding vibratory feeder 11 and the first torsion assembly 2 are spaced apart on the support frame 4 along a second direction. The first conveying member 12 is movably connected to the support frame 4, and the workpiece 10 on the feeding vibratory feeder 11 is conveyed to the first torsion assembly 2 through the first conveying member 12; wherein, the first direction is perpendicular to the second direction. In this embodiment, the second direction is the adjacent direction. Figure 1The X-axis is used in the process. By introducing a support frame 4 and planning the vertical layout of the feeding vibratory feeder 11 and the torsion component, a compact and stable automated workstation is constructed. The space utilization and operation flow of the equipment are optimized, making the entire process from automatic feeding to precision torsion seamless. While ensuring the aforementioned torsion quality advantages, the continuity of production and overall efficiency are significantly improved. It is understood that the feeding vibratory feeder 11 is a mature existing technology in the field of automation, and it is not an improvement point of this application. Its function is to use its internal track and vibration sorting principle to automatically orient the messy rotating spring workpiece 10 and output a preset posture of "standing" along the first direction (i.e., the axis of the torsion component), preparing for subsequent automatic conveying and clamping torsion. The innovation of this application lies in the unique layout of the entire system and the subsequent collaborative torsion method after utilizing this existing feeding device. At the same time, the first conveying component 12 can be composed of a gripping component 121 and a driving component. The driving component moves the gripper 121 to the discharge port of the vibratory feeder 11 → the gripper 121 actuates, clamping the workpiece 10 in an "upright" position → the driving component then moves the gripper 121 and the workpiece 10, precisely transporting them to the working position of the first torsion assembly 2. The gripper 121 can be a pneumatic finger or a dedicated gripper, its function being to reliably hold the single workpiece 10 output by the vibratory feeder 11. The driving component can be a linear module (such as a cylinder or a motor-driven slide), its function being to drive the gripper 121, which has clamped the workpiece 10, to perform precise linear motion. Through this automated "grip-move-release" process, the first conveyor 12 achieves unmanned, high-precision transfer of the workpiece 10 from the vibratory feeder to the first torsion assembly 2.

[0024] In one embodiment, the conveying assembly 1 further includes a linear vibratory feeder 13 and a second conveyor 14. The feeding vibratory plate 11, the linear vibratory feeder 13, the second conveyor 14, and the first torsion assembly 2 are arranged sequentially along a second direction. The workpiece 10 on the feeding vibratory plate 11 is conveyed to the second conveyor 14 via the linear vibratory feeder 13. The second conveyor 14 can convey the workpiece 10 on it to the gripping station along a third direction. The workpiece 10 at the gripping station is conveyed to the first torsion assembly 2 via the first conveyor 12. The first direction, the second direction, and the third direction are perpendicular to each other. In this embodiment, the third direction is the auxiliary direction. Figure 1The Y-axis of the process is incorporated. By introducing a linear vibratory feeder 13 and a second conveyor 14, arranged sequentially with the vibratory feeder 11 and the first conveyor 12 along the second direction, a multi-step, highly stable precision production line is constructed. This design of "vibratory feeder → linear vibratory feeder → second conveyor 14 (buffering and positioning) → first conveyor 12 (transfer) → torsion assembly" achieves smooth material transition and precise positioning. It separates continuous feeding from cycle-based processing, effectively eliminating equipment interference and ensuring that each torsion cycle has a precisely positioned workpiece 10 ready to go, thereby improving the reliability of individual links and further optimizing the overall machine's cycle time and production efficiency. The spatial layout with three mutually perpendicular directions makes the equipment structure compact, the action logic clear, and avoids conflicts in motion trajectories. Among them, the linear vibratory feeder 13 is a common existing technology component in automated equipment. This application only applies this mature component and does not make any improvements to it. Its function is to transport the workpieces 10, initially sorted and output by the vibratory feeder, over a long distance in a single, directional, and stable manner, while also acting as a buffer and connector to ensure a continuous and stable supply of workpieces 10 to the next stage (i.e., the second conveyor 14). Understandably, the "position to be picked up" refers to a pre-defined, static, and fixed location in the automated production line. It serves as a "transfer point" where workpieces 10 pause and wait stably to be picked up by the subsequent first conveyor 12.

[0025] In one embodiment, the second conveying member 14 includes a first driving member 141 and a moving block 142. The moving block 142 is connected to the output end of the first driving member 141. The first driving member 141 is used to drive the moving block 142 to reciprocate along a third direction. The moving block 142 has a receiving groove 1421 on the side facing the vibrating feeder 13. The feeding groove 131 of the vibrating feeder 13 passes through the vibrating feeder 13 along the second direction, and the receiving groove 1421 can connect to the feeding groove 131 of the vibrating feeder 13. In this embodiment, the receiving groove 1421 is a groove with a shape that matches the workpiece 10, and its core function is to accurately receive a single workpiece 10. When the moving block 142 moves to the end of its stroke and aligns with the feeding groove 131 of the vibrating feeder 13, the receiving groove 1421 is exactly aligned with the outlet of the feeding groove 131, ready to receive a workpiece 10. When the moving block 142 carries a workpiece 10 and moves to the gripping station so that the first conveyor 12 can grip it, the receiving groove 1421 of the moving block 142 will be offset from the feeding groove 131 of the vibrating feeder. At this point, the receiving slot 1421 is no longer connected to the feeding slot 131, and the solid side wall of the moving block 142 will move precisely to block the outlet of the feeding slot 131. The subsequent workpiece 10 queue in the direct vibration feeder is blocked by this "wall," unable to continue moving forward or fall, thus ensuring the orderly operation of the workflow. By concretizing the second conveying component 14 into a moving block 142 with a receiving slot 1421 consisting of the first driving component 141, a reliable single workpiece 10 indexing and positioning mechanism is achieved. A precise and reliable conversion from continuous feeding to intermittent gripping is realized. The moving block 142 and its receiving slot 1421, as a movable "single workpiece 10 fixture," can not only accurately receive and isolate a single workpiece 10, but also block the feeding slot 131 at a specific position through its side wall, effectively preventing jamming or chaos caused by the accidental fall of subsequent workpieces 10 during the transfer process. This significantly improves the stability and reliability of the equipment operation, structurally eliminating common failures in the feeding process and providing a solid guarantee for subsequent high-precision torsion. Furthermore, the moving block 142 is slidably connected to the guide rail, which extends along a third direction, ensuring the accuracy of the moving block 142's movement.

[0026] In one embodiment, the first conveying member 12 includes a gripping member 121, a first connecting seat 122, a second connecting seat 123, a second driving member 124, a third driving member 125, and a fourth driving member 126. The second driving member 124 is disposed on the support frame 4. The first connecting seat 122 is connected to the output end of the second driving member 124. The second driving member 124 is used to drive the first connecting seat 122 to reciprocate along a second direction. The third driving member 125 and the second connecting seat 123 are disposed on the first connecting seat 122. The second connecting seat 123 is connected to the output end of the third driving member 125. The third driving member 125 is used to drive the second connecting seat 123 to reciprocate along a third direction. The fourth drive component 126 is located on the second connecting seat 123. The gripper 121 is connected to the output end of the fourth drive component 126. The fourth drive component 126 is used to drive the gripper 121 to reciprocate along the first direction; wherein, the first direction, the second direction, and the third direction are perpendicular to each other. By concretizing the first conveyor 12 into a three-axis Cartesian coordinate robot (composed of the second, third, and fourth drive components 126), high degree of freedom and high precision movement of the gripper 121 in three-dimensional space is achieved. Its core beneficial effect is that it gives the gripping end a great degree of motion flexibility, enabling it to accurately complete complex material handling paths. This design allows the gripper 121 to first descend from above (the first direction) to avoid interference, then move horizontally along the second and third directions, accurately reaching the gripping station above the second conveyor 14, then descending and gripping the workpiece 10, and finally safely and accurately transferring the workpiece 10 to the clamping center (working position) of the first torsion assembly 2 with an optimized trajectory. This avoids interference with surrounding mechanisms and ensures the positioning accuracy of workpiece 10 during handover, laying a solid foundation for subsequent high concentricity torsion. Understandably, the gripper 121 can be a two-finger pneumatic gripper. By controlling the opening and closing of its two gripping fingers through airflow, the gripping and releasing actions of workpiece 10 are reliably achieved. This is the most direct and efficient existing technical solution for automated gripping. Since it needs to drive the entire first connecting seat 122 and all its components to move along the second direction for potentially long distances, the second drive unit 124 often adopts a servo motor (or stepper motor) combined with a synchronous belt. This motor-belt structure can provide high-speed, smooth, and precise long-distance linear motion. The third drive unit 125 and the fourth drive unit 126 can adopt a cylinder or servo motor-screw structure to achieve more precise position and speed control.

[0027] In one embodiment, a feeding structure 5 is provided on the support frame 4. Along the second direction, the first torsion assembly 2 is located between the feeding vibratory feeder 11 and the feeding structure 5. The workpiece 10 processed by the first torsion assembly 2 and the second torsion assembly 3 is conveyed to the feeding structure 5 through the gripper 121. By introducing the feeding structure 5 and arranging it sequentially with the feeding vibratory feeder 11 and the first torsion assembly 2 along the second direction, a complete integrated fully automated production line of "feeding-processing-feeding" is constructed. This achieves a closed-loop production process and optimized spatial layout.

[0028] In one embodiment, the gripper 121 includes a first sub-grip 1211 and a second sub-grip 1212, which are spaced apart along a second direction. Both the first sub-grip 1211 and the second sub-grip 1212 are connected to the output end of the fourth drive member 126. By setting the gripper 121 as a first sub-grip 1211 and a second sub-grip 1212 spaced apart along the second direction, and synchronously driving them by the same fourth drive member 126, a highly efficient "grab and release, parallel operation" mode is achieved. This optimizes the equipment's working cycle and achieves near-seamless material flow. Specifically, when the first conveyor 12 moves, the first sub-grip 1211 can grip a new workpiece 10 to be processed, while the second sub-grip 1212 simultaneously carries a processed workpiece 10. When they move to the processing and unloading positions, the two sub-grippers 121 can simultaneously perform "unloading" and "gripping" actions. This design virtually eliminates the inherent waiting time of a single gripper 121 during loading and unloading, highly parallelizing the originally serial gripping, moving, and placing process, thereby significantly improving the overall production efficiency and capacity of the equipment. The first sub-gripper 1211 and the second sub-gripper 1212 can be mature two-finger pneumatic grippers. They are installed side by side, with independent functions, and their clamping and releasing can be controlled separately, thereby achieving simultaneous gripping or releasing of two workpieces 10. Understandably, the fourth drive unit 126 may include two independent cylinders, with the piston rod of one cylinder connected to the first sub-gripper 1211 and the piston rod of the other cylinder connected to the second sub-gripper 1212. In other embodiments, the fourth drive member 126 includes a cylinder and a mounting plate disposed on the piston rod of the cylinder. The first sub-grip member 1211 and the second sub-grip member 1212 are disposed on the mounting plate, and the two sub-grip members 121 are driven to move synchronously by a cylinder.

[0029] In one embodiment, the torsion mechanism further includes a fifth drive member 6. The second torsion assembly 3 is connected to the output end of the fifth drive member 6. The fifth drive member 6 drives the second torsion assembly 3 to reciprocate along a first direction, so that the second torsion assembly 3 moves closer to or further away from the first torsion assembly 2. By adding the fifth drive member 6 to the second torsion assembly 3, enabling it to reciprocate along the first direction (i.e., the torsion axis), a key adaptive adjustment capability is provided for the core torsion function. This greatly improves the compatibility of the equipment with workpieces 10 of different specifications and the reliability of clamping. By adjusting the axial distance between the two torsion assemblies, the equipment can easily adapt to spring terminals of different lengths, significantly expanding the processing range of the equipment. This ensures that the workpiece 10 is accurately centered and firmly clamped before torsion, preventing slippage or displacement of the workpiece 10 during the torsion process, and further ensuring the concentricity of the torsion, thereby improving product quality and processing consistency. The fifth drive member 6 can be a motor-screw structure.

[0030] In one embodiment, the first torsion assembly 2 includes a first gripper 21 and a sixth drive member 22. The first gripper 21 is connected to the output end of the sixth drive member 22, and the sixth drive member 22 applies a torque along the first torsion direction to the first end through the first gripper 21. The second torsion assembly 3 includes a second gripper 31 and a seventh drive member 32. The output ends of the second gripper 31 and the seventh drive member 32 are connected. The seventh drive member 32 applies a torque along the second torsion direction to the second end through the second gripper 31. The sixth drive member 22 and the seventh drive member 32 can be torsion motors. The first gripper 21 and the second gripper 31 can be three-finger pneumatic grippers. By specifying the first torsion assembly and the second torsion assembly 3 as structures where the sixth drive member 22 and the seventh drive member 32 directly drive the first and second grippers 31 respectively, a high-precision and highly controllable core for the torsion action is established. Independent, precise, and powerful direct control of the torsion process at both ends of the workpiece 10 is achieved. This allows each gripper to apply a pure and controlled rotational torque to the end of the workpiece 10 under the drive of its corresponding drive member. Because the two drive components can precisely control the rotation angle, speed, and torque, and strictly maintain opposite directions and synchronous operation, this ensures that the torsional force is precisely applied along the axial direction of the workpiece 10, fundamentally eliminating problems such as torsional misalignment, workpiece 10 twisting, or surface damage caused by asynchronous or uneven torque. This structure is the ultimate guarantee for achieving high-quality, high-consistency torsional machining, directly transforming the technical advantages of this invention into stable and reliable product quality.

[0031] According to the torsion mechanism provided in this embodiment of the present invention, the conveying component 1 conveys the workpiece 10 (e.g., a national standard charging socket spring terminal) to the working position of the first torsion component 2 according to a preset path, so as to achieve precise loading and positioning of the workpiece 10. Since the first torsion component 2 and the second torsion component 3 are arranged opposite to each other along the first direction, when the workpiece 10 arrives at the first torsion component 2, the first torsion component 2 clamps the first end of the workpiece 10 and applies a torque along the first torsion direction (e.g., clockwise) to the end. At the same time, the second torsion component 3 clamps the second end of the workpiece 10 and applies a torque in the second torsion direction (e.g., counterclockwise) opposite to the first torsion direction to the end. Under the combined action of the two opposing torques, the workpiece 10 is torsioned to form the required torsion spring structure. After the torsion processing is completed, the first torsion component 2 and the second torsion component 3 release the workpiece 10 so that the processed workpiece 10 can be transferred in the future. The workpiece 10 is automatically conveyed by the conveying component 1, replacing manual feeding. Simultaneously, the first torsion component 2 and the second torsion component 3 apply reverse torque to both ends of the workpiece 10 to complete the torsion, significantly reducing manual operation and effectively solving the problem of low efficiency in manual operation. This significantly improves the production efficiency of national standard charging socket spring terminals and meets the needs of mass production. In addition, the first torsion component 2 and the second torsion component 3 precisely clamp both ends of the workpiece 10 through mechanical structure and apply controllable reverse torque, avoiding the problem of misalignment of the workpiece 10 caused by uneven force control and torsion angle deviation in manual operation. This ensures the processing accuracy of the torsion spring structure, thereby ensuring that the insertion and extraction force of the finished spring terminals meets the usage standards, reducing the defect rate, and reducing direct manual intervention in the torsion operation, thus reducing the labor intensity of operators.
