Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a semi-automatic device for automatic wire harness pulling and inspection. Background Technology

[0002] Pulling the lead wire into the soft plug provides stable fixation and protection for the lead wire, preventing it from loosening, becoming scattered, or being damaged by external interference, thus ensuring the reliability of the electrical connection. Testing is conducted to ensure that the position and state of the lead wire after being pulled into the soft plug meet the design requirements, avoiding problems such as the lead wire not being pulled in properly or the soft plug not sealing tightly, which affect the performance and safety of the equipment, thereby ensuring that the entire wiring harness system can transmit power and signals stably and accurately.

[0003] Currently, existing wire harness pulling and testing equipment usually requires manual operation. Although it can perform some wire harness processing operations and meet basic production needs to a certain extent, it is difficult to automatically complete the continuous and demanding operations such as lead wire pre-pulling, accurate detection of heat shrink tubing size, and subsequent accurate pulling of lead wire into soft plug. This results in low automation, poor operational accuracy, low production efficiency, and inconsistent product quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in automatically completing continuous and demanding operations like lead wire pre-pulling, accurate detection of heat shrink tubing dimensions, and subsequent accurate pulling of the lead wire into the soft plug, which leads to low automation, efficiency, and product quality. Therefore, this invention proposes a semi-automatic device for automatic wire harness pulling and detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A semi-automatic device for automatic wire harness pulling and inspection includes: The machine body has a working compartment inside, and a bottom plate is fixedly installed on the bottom wall of the working compartment; The base plate is provided with a moving mechanism, which is used to drive the wire pulling mechanism to move in the X, Y and Z axis directions to pull the lead wire out a set distance. The moving mechanism is provided with a wire pulling mechanism, which is used to pull the lead wire into the soft plug to complete the insertion of the lead wire.

[0006] In one possible design, the moving mechanism includes two X-axis single-axis modules symmetrically fixedly disposed on the top of the base plate. A Y-axis single-axis module is fixedly disposed on the top of the movable sliders on both X-axis single-axis modules. A support frame is fixedly disposed on the top of the movable sliders on both Y-axis single-axis modules. A moving frame is slidably disposed on the front side of both support frames. A Z-axis cylinder is fixedly disposed on the inner side of both support frames. The two Z-axis cylinders are respectively fixedly connected to the bottom of the two moving frames.

[0007] In one possible design, a parallel finger cylinder I is fixedly installed on one side of each of the two movable frames, and a wire harness clamp is fixedly installed on each of the two movable grippers on the two parallel finger cylinders I. A clamping plate is fixedly installed on the side of the two wire harness clamps that are close to each other.

[0008] In one possible design, the top of the base plate is located inside the X-axis single-axis module and below the two Y-axis single-axis modules, and a fixed bracket is fixedly installed on each of the two fixed brackets. A motor is fixedly installed on the front side of each of the two fixed brackets, and a parallel finger cylinder II is rotatably installed on each of the two fixed brackets near the motor. A soft plug clamp is fixedly installed on each of the two movable grippers on the parallel finger cylinder II.

[0009] In one possible design, the rear side of the fixed frame is rotatably provided with a rotating shaft, and a synchronous pulley is fixedly provided on the outside of the two rotating shafts. The two synchronous pulleys are externally driven by the same synchronous belt, and the two rotating shafts are respectively fixedly connected to the motor output shaft and the parallel finger cylinder II.

[0010] In one possible design, a gantry is fixedly mounted on the top of the base plate, and two cameras are symmetrically fixedly mounted on one side of the two gantry frames, with supplementary lights fixedly mounted on the bottom outer ring of the cameras.

[0011] In one possible design, a sealing plate is fixedly installed on the machine body at the working compartment, and two inlet windows are symmetrically opened on one side of the sealing plate corresponding to the soft plug clamp.

[0012] In this application, when the wire harness is first used, the worker puts it in through the two windows on the cover plate so that the wire harness is placed between the two soft plug clamps. When placing it, the left and right workstations should be placed in a cross manner. After the wire harness is placed in the soft plug clamp, the parallel finger cylinder II is activated. The two movable jaws on the parallel finger cylinder II move in a direction that is close to each other, which drives the soft plug clamps on the two movable jaws to move, thereby clamping and fixing the wire harness placed in the soft plug clamp. Next, start the left or right workstation as needed by moving the corresponding lever. After the lever is activated, two cameras symmetrically fixed on one side of the gantry at the top of the base plate begin to work, taking pictures of the wire harness at the corresponding workstation. During this process, the motor starts, and the motor output shaft drives the rotating shaft fixed to it to rotate. The synchronous wheel fixed outside the rotating shaft rotates accordingly. Through the same synchronous belt sleeved outside the two synchronous wheels, the other synchronous wheel is driven to rotate, which in turn drives the other rotating shaft fixed to the synchronous wheel to rotate. Finally, the wire harness clamped in the soft plug holder rotates. In this way, the camera can capture the position of each color of wire harness, completing the color position detection of the six wire harnesses and the detection of whether the initial position of the wire harness meets the requirements. After the test is completed, the two X-axis single-axis modules start working. (The two X-axis single-axis modules are driven by a drive motor to drive the transmission mechanism (such as the rotation of a lead screw to drive the linear movement of the nut seat, or the synchronous belt pulley to drive the slider to move along the guide rail). Combined with the guide mechanism, stability is ensured, and precise position control is achieved using limit switches and feedback systems (such as servo encoders). Finally, the rotational motion is converted into the linear reciprocating motion of the slider.) The movement of the X-axis slider can drive the Y-axis single-axis module fixed on its top to move. At this time, the two Y-axis single-axis modules start working. (The two X-axis single-axis modules are driven by a drive motor to drive the transmission mechanism (such as the rotation of a lead screw to drive the linear movement of the nut seat, or the synchronous belt pulley to drive the slider to move along the guide rail). Combined with the guide mechanism, stability is ensured, and precise position control is achieved using limit switches and feedback systems (such as servo encoders). Finally, the rotational motion is converted into the linear reciprocating motion of the slider.) The movement of the Y-axis slider drives the support frame fixed on its top to move. The movable frame, which is slidably set on the front side of the two support frames, moves up and down under the action of the Z-axis cylinder fixed on the inside of the support frame. This causes the parallel finger cylinder I, which is fixed on one side of the movable frame, to move. The parallel finger cylinder I moves closer to the lead wire to be pulled out. Then, the wire harness clamp, which is fixed on the two movable jaws on the parallel finger cylinder I, moves with the movement of the two movable jaws on the parallel finger cylinder I. This allows the wire harness clamp to grab the lead wire in the middle of the wire harness. Then, the lead wire is pulled out a set distance (pre-pulling out) according to the above principle. After the pre-pulling out is completed, the camera takes a picture of the heat shrink tubing on the wire harness. The final size is obtained by analysis and calculation, and the data is transmitted to the PLC. Then, the remaining lead wires are pulled out according to the above operating principle. Finally, the lead wires are pulled into the soft plug to complete the insertion of the lead wires. After the wire harness is pulled out, the wire harness is manually removed through the inlet window on the sealing plate. The left and right stations take materials in a cross manner. Through this process, the entire equipment realizes the automatic wire harness pulling and detection functions.

[0013] This utility model has the following beneficial effects: This invention achieves smooth and precise linear motion of the wire pulling mechanism through the setting of the moving mechanism. It can not only quickly position the wire pulling execution component to the wire harness lead, improving the operation response speed and positioning accuracy, but also flexibly adapt to the processing requirements of different specifications of wire harnesses. It provides reliable displacement guarantee for automated wire harness pulling and inspection, effectively improving production efficiency and product quality stability.

[0014] This invention utilizes a wire-pulling mechanism to precisely and securely clamp the wire harness lead. Through coordination with a moving mechanism, it enables precise pre-pulling of the lead according to set parameters and subsequent insertion of the soft plug. With the assistance of a detection camera, data can be fed back in a timely manner to adjust the wire-pulling action. This not only significantly improves the automation and operational precision of wire harness pulling, effectively ensuring stable product quality, but also reduces manual intervention, lowers labor costs, and ultimately improves overall production efficiency.

[0015] This invention combines a moving mechanism and a wire pulling mechanism to complete operations such as lead wire pre-pulling, heat shrink tubing size detection, and subsequent precise pull-in of the lead wire into the soft plug. This greatly improves the automation level, operational accuracy, and production efficiency of wire harness pulling and detection, ensuring the consistency and stability of product quality, while reducing manual intervention and lowering labor and management costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In one embodiment Reference Figure 1-4 A semi-automatic device, comprising: The main body 1 forms the main frame. A working chamber is opened inside the main body 1. A base plate 2 is fixedly installed on the bottom wall of the working chamber to provide a stable installation foundation for each component.

[0020] The moving mechanism is mounted on the base plate 2 and includes two X-axis single-axis modules 4 symmetrically fixed on the top of the base plate 2 as the basic components for the movement of the moving mechanism in the X-axis direction. Each X-axis single-axis module 4 is equipped with a movable slider. A Y-axis single-axis module 5 is fixedly mounted on the top of each of the two sliders. The Y-axis single-axis module 5 is also equipped with a movable slider, and a support frame 6 is fixedly mounted on the top of its slider. A moving frame 7 is slidably mounted on the front side of each of the two support frames 6, and a Z-axis cylinder 8 is fixedly mounted on the inner side of the support frame 6. The Z-axis cylinder 8 is fixedly connected to the bottom of each of the two moving frames 7. Through the coordinated operation of the X-axis single-axis module 4, the Y-axis single-axis module 5, and the Z-axis cylinder 8, the wire pulling mechanism can move in the X-axis, Y-axis, and X-axis directions. Precise movement in the Z-axis direction (X-axis single-axis module and Y-axis single-axis module (model: YCTH5-8 / 12) mainly consists of drive motor (such as servo motor or stepper motor), transmission mechanism (ball screw or synchronous belt), guide mechanism (linear guide rail), moving platform (slider), base and support structure, as well as auxiliary components such as coupling, limit switch, proximity switch, etc. Its working principle is to drive the transmission mechanism through the motor (such as the screw rotation to drive the nut seat to move linearly, or the synchronous belt pulley to drive the slider to move along the guide rail), combined with the guide mechanism to ensure stability, and use limit switches and feedback system (such as servo encoder) to achieve precise position control, and finally convert the rotational motion into the linear reciprocating motion of the slider).

[0021] The wire pulling mechanism is mounted on the moving mechanism. Parallel finger cylinders I9 are fixedly mounted on one side of each of the two moving frames 7. Wire harness clamps 10 are fixedly mounted on the two movable grippers of the parallel finger cylinders I9. A clamping plate is fixedly mounted on the side of the wire harness clamps 10 that is close to each other. During operation, the parallel finger cylinders I9 (model: MHZL-16 / 20 / 25 / 32D) drive the grippers to clamp the wire harness clamps 10 and pull the wires out of the set distance under the action of the moving mechanism. Then, the operation continues to pull the wires into the soft plug, completing the insertion of the wires (there are six wires in total, and a heat shrink tubing is fitted between the six wires).

[0022] On the base plate 2, inside the X-axis single-axis module 4 and below the two Y-axis single-axis modules 5, a fixing bracket 11 is fixedly installed. A motor 12 is fixedly installed on the front side of the two fixing brackets 11. A parallel finger cylinder II 13 (model: MHZL-16 / 20 / 25 / 32D) is rotatably installed near the motor 12. A soft plug clamp 14 is fixedly installed on the two movable grippers on the parallel finger cylinder II 13. The soft plug clamp 14 is located in front of the wire harness clamp 10. When the wire harness is manually placed into the soft plug clamp 14, the parallel finger cylinder II 13 can drive the soft plug clamp 14 to clamp the wire harness.

[0023] A rotating shaft is rotatably mounted on the rear side of the fixed frame 11. Synchronous pulleys 15 are fixedly mounted on the outside of the two rotating shafts. The two synchronous pulleys 15 are externally driven by the same synchronous belt 16. The two rotating shafts are respectively fixedly connected to the output shaft of the motor 12 and the parallel finger cylinder II 13. After the motor 12 starts, it drives the parallel finger cylinder II 13 to rotate through the synchronous belt 16 and the synchronous pulleys 15, which in turn drives the wire harness clamped on the soft plug clamp 14 to rotate, so as to facilitate subsequent photographing and inspection.

[0024] This application can be used in the field of semi-automatic equipment technology for automatic wire harness pulling and testing, and can also be used in other fields applicable to this application.

[0025] In another embodiment Reference Figure 1-3 A semi-automatic device for automatic wire harness pulling and inspection is described. It is applied to the technical field of semi-automatic equipment for automatic wire harness pulling and inspection. A gantry frame 17 is fixedly installed on the top of the base plate 2. Two cameras 18 (including lenses) are symmetrically fixed on one side of the two gantry frames 17. A supplementary light is fixedly installed on the bottom outer ring of the camera 18. The two cameras 18 take pictures of the wire harness at the corresponding workstation. The color position of the six wire harnesses can be identified, and the initial position of the wire harness can be detected as meeting the requirements.

[0026] The machine body 1 is fixedly installed with a sealing plate 3 in the working chamber. Two wire inlet windows are symmetrically opened on one side of the sealing plate 3 corresponding to the soft plug clamp 14. The wire harness is placed into the soft plug clamp 14 by the operator through the wire inlet window. When placing, the left and right workstations are placed in a cross manner. After the wire harness is pulled, the wire harness is also taken out by the operator through the wire inlet window.

Those skilled in the art can make any selections according to their needs or convenience.
