Description

Technical Field

[0001] This utility model specifically relates to the field of wire end positioning technology, and more specifically to a conductive wire end positioning mechanism. Background Technology

[0002] In the manufacturing of products such as wires and cables and electronic wire harnesses, accurate positioning of wire ends is a key prerequisite for ensuring the quality of subsequent processing. Insufficient positioning accuracy of wire ends will directly lead to problems such as wire end processing defects and wire harness assembly misalignment, which in turn will affect the electrical performance and service life of the products, while also reducing production efficiency.

[0003] Currently, the main wire end positioning methods in the electronic wire harness industry mostly adopt sensor detection. However, this method has certain limitations. It is constrained by the performance of the sensor itself and installation errors, making it difficult to meet the stringent positioning accuracy requirements of high-end electronic wire harnesses. Even a small positioning deviation can lead to poor contact between the terminal and the wire, causing signal transmission failure. Utility Model Content

The conductive shaft and the conductive positioning plate are respectively connected to wires. When no material is loaded, the two are not conductive. When the wire harness is loaded, the wire harness pushes the conductive shaft to move and forms effective contact with the conductive positioning plate, the circuit is connected, and the trigger indicator light is lit, providing intuitive feedback on the accurate positioning of the wire end. This solves the problem of insufficient accuracy in traditional wire end positioning and is especially suitable for scenarios in the wire harness processing field where high accuracy and conductivity of wire end positioning are required, thereby improving production efficiency and product quality.

[0007] As a further technical solution of this utility model, a baffle is fixedly connected to one end of the guide shaft, and the diameter of the baffle is larger than the diameter of the hole opened in the middle of the support. The other end of the guide shaft has a certain gap with the guide positioning plate. An open clamping plate is fixedly connected to the middle of the guide shaft, and the diameter of the open clamping plate is larger than the diameter of the hole on the support.

[0008] As a further technical solution of this utility model, a rectangular groove is provided in the middle of the base, and a servo motor is fixedly connected to the bottom of the groove. A coupling is installed at one end of the output shaft of the servo motor, and a lead screw is fixedly connected to the other end of the coupling. A baffle is fixedly connected to the tail end of the lead screw. The front end of the lead screw extends to the bottom of the bracket and is rotatably connected to the bracket.

[0009] As a further technical solution of this utility model, the lead screw is provided with a first slide rail on both sides, the first slide rail is fixedly connected to the base, and a slide block is slidably connected on the first slide rail. The slide block is fixedly connected to the bracket. Both ends of the first slide rail are provided with a stop block, and the stop block is fixedly connected to the base.

[0010] As a further technical solution of this utility model, an inlet pipe is fixedly connected above the upright plate on one side of the bracket, opposite to the guide shaft, and a second slide rail is provided at the bottom of the inlet pipe. The second slide rail is fixedly connected to the upright plate on one side of the bracket. Two sets of slide seats are slidably connected on the second slide rail, and each slide seat is fixedly connected to a clamp, and the clamps are symmetrically arranged.

[0011] As a further technical solution of this utility model, the gripper is provided with a control plate at the bottom, and a sliding groove is provided on the control plate. The sliding groove is V-shaped, and a sliding shaft is provided in the sliding groove. One end of the sliding shaft is fixedly connected to the gripper, and the other end is fitted with a rotating wheel and rotatably connected to the sliding groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the cooperation of the conductive shaft and the conductive positioning plate, uses the circuit formed by the first and second wires to detect the continuity status in real time when the wire end is positioned. The indicator light can intuitively reflect whether the positioning is accurate and whether the contact is good, without the need for additional testing procedures, thus greatly improving production efficiency.

[0017] 2. In this utility model, the conductive shaft is movably connected to the support and works with a spring. When the wire harness is being fed, the conductive shaft is pushed to move and contact the conductive positioning plate, thus completing the circuit connection between the first and second wires. When not being fed, the elasticity of the spring can separate the conductive shaft and the conductive positioning plate, thus disconnecting the circuit and turning off the indicator light. The baffle and the open clamping plate of the conductive shaft form a bidirectional limit, ensuring that it moves flexibly within its effective stroke and avoiding excessive displacement that would affect the positioning accuracy. This is especially suitable for high-precision positioning scenarios involving small wire ends and precision wire harnesses.

[0018] 3. In this utility model, the servo motor drives the bracket to move as a whole through the lead screw and the first slide rail, realizing the automatic adjustment of the positioning position. The cylinder drives the V-shaped sliding groove of the control board to drive the gripper to open and close symmetrically, so as to stably clamp the wire harness when the wire end is positioned, without the need for manual intervention. It is suitable for the high-speed operation requirements of automated production lines and reduces labor costs and operation errors. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 In this embodiment of the utility model, a base 1 is included. A bracket 7 is provided on one side of the base 1, and a support 14 is fixedly connected to the top of the bracket 7. A hole is opened in the middle of the support 14, and a conductive shaft 19 is provided in the hole. The conductive shaft 19 is movably connected to the support 14, and a spring 18 is installed on the conductive shaft 19. A first wire 15 is provided on one side of the spring 18. The first wire 15 is fixedly connected to the conductive shaft 19 through a fixing plate below. A conductive positioning plate 17 is fixedly connected to the outside of one side of the support 14, and a second wire 16 is fixedly connected to the conductive positioning plate 17.

[0029] By adopting the above technical solution, the conductive shaft 19 is movably connected to the support 14. Under normal conditions, under the elastic force of the spring 18, the conductive shaft 19 and the conductive positioning plate 17 maintain a certain gap, and the first wire 15 and the second wire 16 are in a disconnected state. When the end of the wire harness is pushed to the positioning position, it will push the conductive shaft 19 to overcome the elastic force of the spring 18 and move to the conductive positioning plate 17 until the two contact. At this time, the first wire 15 and the second wire 16 contact and conduct, forming a path, which directly reflects whether the wire end is accurately positioned. Its positioning accuracy is higher than that of traditional sensor detection, and it can accurately capture the positioning position of the wire end.

[0030] In this embodiment, a baffle is fixedly connected to one end of the conductive shaft 19, and the diameter of the baffle is larger than the diameter of the hole opened in the middle of the support 14. The other end of the conductive shaft 19 has a certain gap with the conductive positioning plate 17. An open clamping plate 20 is fixedly connected to the middle of the conductive shaft 19, and the diameter of the open clamping plate 20 is larger than the diameter of the hole on the support 14.

[0031] By adopting the above technical solution, the diameter of the baffle at one end of the conductive shaft 19 is larger than the diameter of the hole in the middle of the support 14, which can prevent the conductive shaft 19 from moving excessively in the direction of the conductive positioning plate 17 when pushed by the wire harness. The diameter of the opening plate 20 in the middle is also larger than the hole diameter, which prevents the conductive shaft 19 from coming out of the hole in the support 14 under the action of the return force of the spring 18. The two form a bidirectional limit, strictly controlling the movement stroke of the conductive shaft 19, ensuring that it always moves within the preset range, and avoiding component collision damage or conduction failure due to excessive displacement.

[0032] In this embodiment, a rectangular groove is provided in the middle of the base 1, and a servo motor 3 is fixedly connected to the bottom of the groove. A coupling 4 is installed at one end of the output shaft of the servo motor 3, and a lead screw 5 is fixedly connected to the other end of the coupling 4. A baffle 6 is fixedly connected to the tail end of the lead screw 5. The front end of the lead screw 5 extends to the bottom of the bracket 7 and is rotatably connected to the bracket 7.

[0033] By adopting the above technical solution, the output shaft of the servo motor 3 is connected to the lead screw 5 through the coupling 4, which can accurately convert the rotation of the motor into the rotation of the lead screw 5. Since the lead screw 5 and the bottom of the bracket 7 form a threaded fit, when the lead screw 5 rotates, it will drive the bracket 7 to move linearly along the axial direction, thereby driving the positioning components such as the support 14 to move synchronously. It can accurately adjust the positioning reference position according to the length of different wire harnesses, processing requirements and working scenarios, which greatly improves the adaptability of the mechanism to diverse production scenarios.

[0034] In this embodiment, the lead screw 5 is provided with first slide rails 2 on both sides. The first slide rails 2 are fixedly connected to the base 1, and a slide block is slidably connected on the first slide rails 2. The slide block is fixedly connected to the bracket 7. Both ends of the first slide rails 2 are provided with blocks, and the blocks are fixedly connected to the base 1.

[0035] By adopting the above technical solution, the first slide rails 2 on both sides of the lead screw 5 are fixedly connected to the base 1, and the bracket 7 slides with the slide rail through the slide block to form a symmetrical guide support structure, which can ensure that the bracket 7 moves linearly along the axis of the slide rail, avoid the bracket tilting and shaking caused by the unilateral force of the lead screw 5 or installation error, reduce jamming or offset during movement, and ensure the positional accuracy of the bracket 7 and the positioning components.

[0036] Furthermore, the stops at both ends of the first slide rail 2 are fixed to the base, which can provide rigid blocking when the bracket moves to the limit of its stroke, preventing the bracket 7 from exceeding the safe range due to overdrive of the servo motor 3 or failure of the control system, thus protecting the equipment from damage.

[0037] In this embodiment, an inlet pipe 11 is fixedly connected above the upright plate on one side of the bracket 7, opposite to the guide shaft 19, and a second slide rail 10 is provided at the bottom of the inlet pipe 11. The second slide rail 10 is fixedly connected to the upright plate on one side of the bracket 7. Two sets of slide seats are slidably connected on the second slide rail 10, and each slide seat is fixedly connected to a clamp 12. The clamps 12 are symmetrically arranged.

[0038] By adopting the above technical solution, the inlet pipe 11 is fixed above the upright plate of the bracket 7 and opposite to the guide shaft 19. Its internal channel can accurately guide the conveyed wire harness, ensuring that the wire harness can be pushed to the guide shaft 19 along the preset path, avoiding the wire harness from deviating during the conveying process, thereby ensuring that the wire end can accurately contact and push the guide shaft 19.

[0039] Furthermore, the two sets of symmetrical grippers 12 slidably connected on the second slide rail 10 can move synchronously in opposite directions along the slide rail to form a symmetrical clamping force on the wire end, ensuring that the wire end is subjected to uniform force during clamping, avoiding wire end deviation due to unilateral force, and ensuring that the position of the wire end after clamping is consistent with the reference during positioning, providing a stable workpiece posture for subsequent processing steps such as wire stripping and crimping.

[0040] In this embodiment, the gripper 12 is provided with a control plate 9 at its bottom, and a sliding groove is provided on the control plate 9. The sliding groove is V-shaped, and a sliding shaft is provided in the sliding groove. One end of the sliding shaft is fixedly connected to the gripper 12, and the other end is fitted with a rotating wheel and rotatably connected to the sliding groove.

[0041] By adopting the above technical solution, the V-shaped sliding groove on the control board 9 provides a linkage trajectory for the sliding shafts of the two sets of grippers 12. When the control board 9 moves up and down, the sliding shaft slides synchronously along the inclined surfaces on both sides of the V-shaped groove. Since the two sides of the V-shaped groove are symmetrical, the two sets of grippers 12 will move symmetrically in opposite directions along the second slide rail 10 under the drive of the sliding shaft. When the control board 9 moves up, the grippers 12 move closer to each other to clamp. When the control board 9 moves down, the grippers 12 move further apart to release. This ensures that the movement distance of the two grippers is completely consistent, avoids clamping misalignment caused by unilateral offset, and ensures that the wire end is always clamped in the center position. The rotating wheel at the end of the sliding shaft is rotatably connected to the V-shaped groove, which converts sliding friction into rolling friction, reduces the resistance during the movement, and makes the opening and closing action of the grippers 12 more stable and smooth, avoiding unstable clamping or damage to the wire end due to jamming.

[0042] In this embodiment, a sliding seat is fixedly connected to the outside of the control board 9, and a slide rail is slidably connected to the sliding seat. The slide rail is fixedly connected to the upright plate of the bracket 7.

[0043] By adopting the above technical solution, the sliding seat on the outside of the control board 9 slides in cooperation with the slide rail on the support plate 7, which restricts the movement trajectory of the control board, so that it can only move up and down in the vertical direction along the slide rail. This prevents the control board 9 from shifting left and right, tilting or shaking during the driving process of the cylinder 8. This directional guidance is the basis for the synchronous movement of the gripper 12 driven by the V-groove. It can prevent the gripper from opening and closing asynchronously due to the posture deviation of the control board 9, and ensure that the clamping position always accurately corresponds to the wire end positioning area.

[0044] In this embodiment, the bottom of the control board 9 is provided with a cylinder 8, which is fixedly connected to the upright plate of the bracket 7, and the cylinder head of the cylinder 8 is connected to the control board 9.

[0045] By adopting the above technical solution, the cylinder 8 provides driving force through compressed air. Its cylinder head is directly connected to the control board 9, which can output a continuous and uniform thrust or pull force, driving the control board 9 to move up and down smoothly. By adjusting the pressure of the compressed air, the output force of the cylinder 8 can be precisely controlled, thereby adjusting the clamping force of the gripper 12 on the wire end. This adjustability allows the mechanism to adapt to wire harnesses of different materials and diameters, improving the versatility of the mechanism.

[0046] In this embodiment, a signal light 13 is fixedly connected to the top of the support 14, and the signal light 13 is electrically connected to the first wire 15 and the second wire 16.

[0047] By adopting the above technical solution, the signal light 13 is electrically connected to the first wire 15 and the second wire 16 to form a complete conductive circuit. When the wire end pushes the conductive shaft 19 to contact the conductive positioning plate 17, the circuit is connected and the signal light 13 lights up; when the wire end is not in place or is detached, the circuit is disconnected and the signal light goes out. This allows the operator or the automation system to instantly determine whether the wire end is accurately positioned without additional detection steps, which greatly shortens the positioning confirmation time.

[0048] The working principle of this utility model is as follows: First, according to the scenario of the wire harness to be positioned, the servo motor 3 on the base 1 is started by the control system. The servo motor 3 drives the lead screw 5 to rotate through the coupling 4, which will drive the bracket 7 to move smoothly along the first slide rail 2 until it reaches the appropriate wire harness conveying path alignment, thus completing the initial position adjustment of the positioning component.

[0049] Next, the wire harness is fed in from one end of the inlet tube 11. The inlet tube 11 guides the wire harness, ensuring that the wire harness is pushed along the preset path to the conductor shaft 19. As the wire harness continues to advance, its end will contact one end of the conductor shaft 19 and push the conductor shaft 19 to overcome the elastic force of the spring 18 and move in the direction of the conductor positioning plate 17 until the conductor shaft 19 contacts the conductor positioning plate 17. At this time, the first wire 15 fixed to the conductor shaft 19 and the second wire 16 fixed to the conductor positioning plate 17 form a conductive circuit through contact. The indicator light 13 on the top of the support 14 then lights up, indicating that the wire end has been accurately positioned.

[0050] Subsequently, the lighting signal of the signal light 13 is transmitted to the control system. The control system instructs the cylinder 8 on the support plate 7 to start. The cylinder head of the cylinder 8 pushes the control plate 9 to move upward along the slide rail on its outer side. The sliding shaft in the V-shaped sliding groove on the control plate 9 slides synchronously along the inclined surface of the V-shaped groove, thereby driving the two sets of symmetrical grippers 12 to move towards each other along the second slide rail 10 until the grippers 12 hold the positioned wire end, thus fixing the wire end posture for subsequent wire stripping, crimping and other processing steps.

[0051] Finally, after the subsequent processing is completed, the control system commands cylinder 8 to reset, the cylinder head pulls control plate 9 to move downward, the sliding shaft slides in the opposite direction along the V-shaped groove slope, driving the gripper 12 to separate in the opposite direction along the second slide rail 10, releasing the wire end; at the same time, the wire harness is removed, the conductive shaft 19 returns to the initial position under the reset force of spring 18, restores the preset gap with the conductive positioning plate 17, the circuit between the first wire 15 and the second wire 16 is disconnected, the indicator light 13 is turned off, and the mechanism waits for the next positioning operation to complete the entire work cycle.
