Description

Technical Field

[0001] This invention relates to the field of defective product detection devices, and more specifically, to a defective product detection device for automotive wiring harness testing. Background Technology

[0002] Automotive wiring harnesses are critical components in automotive circuits, connecting various electrical and electronic devices and forming the main framework of the vehicle's electrical system. Without wiring harnesses, a car cannot function properly. Automotive wiring harnesses primarily consist of connectors and wires. During production, wires are typically crimped to the pins of the connectors. To ensure the quality of automotive wiring harnesses, a pin-removal test is performed after production to assess the connection reliability and overall quality of the wiring harness, checking the pin's stability.

[0003] During the pin removal test, the insert shaft is usually inserted into the connector and applied to the pin. If the pin is loose, it will detach from the connector. At this time, the insert shaft can be smoothly inserted into the connector, but it cannot establish a connection with the subsequent conductive parts. In this case, the test equipment will issue a prompt indicating that the wire harness is defective and is a non-conforming product.

[0004] Furthermore, if the pins bend during the insertion of the connector, although the pins will not fall out of the connector and the testing equipment may judge it as qualified, in reality, the bent pins may cause unstable connections in subsequent use, thereby affecting the performance and reliability of the automotive wiring harness. Summary of the Invention

[0005] This invention provides a defective product detection device for automotive wiring harness testing, solving the technical problem in related technologies that cannot perform detection when bent.

[0006] The present invention provides a defect detection device for automotive wiring harness testing, including a housing and a fixture, wherein the housing is provided with an insertion mechanism for inserting into the connector to detect the pins; The insertion mechanism includes a shaft for applying force to the pin, and the insertion end of the shaft has a receiving groove for detecting the flatness of the pin, so as to determine that it is in a non-bent state when it is fully fitted onto the pin. The housing is equipped with a continuity detection mechanism that cooperates with the insertion mechanism; The continuity detection mechanism detects the positional state between the insertion mechanism and the conduction detection mechanism to detect the presence of PIN retraction and PIN bending.

[0007] As a further optimization of the present invention, the insertion mechanism further includes a movable seat, a linear driver, and a return component. The movable seat is slidably disposed in the housing and driven by the linear driver. The insertion shaft is slidably disposed on the movable seat and connected to the movable seat through the return component. When the receiving groove is fully fitted onto the PIN pin and driven by the linear driver to perform PIN removal detection, if PIN removal occurs, the insertion shaft cannot ultimately conduct with the continuity detection mechanism.

[0008] As a further optimization of the present invention, the return component includes a return spring and a connecting block. The connecting block is fixedly mounted on the insert shaft and connected to the movable seat through the return spring.

[0009] As a further optimization of the present invention, a polished layer is embedded on the inner circumference of the receiving groove.

[0010] As a further optimization of the present invention, the interior of the receiving groove is provided with a cleaning component; The cleaning component includes a top block, a return spring, brush bristles, and a guide rod. The top block is located inside the receiving groove and is connected to the inner wall of the receiving groove through the return spring. The guide rod is located in the middle of the return spring, with one end fixedly connected to the top block and the other end sliding out of the insertion shaft and fixedly connected to a conductive block. The brush bristles are assembled on the outer periphery of the top block to clean the polishing layer.

[0011] As a further optimization of the present invention, the continuity detection mechanism includes a bushing, a pressure sensor and a return spring. The bushing is fixedly mounted on the movable seat and is correspondingly arranged with the insert shaft. One end of the bushing facing the insert shaft has a through groove adapted to the conductive block. The pressure sensor is slidably mounted inside the through groove. One end of the return spring is connected to the inner wall of the through groove, and the other end is connected to the pressure sensor. The pressure sensor is used to detect pressure when the groove is not completely fitted onto the PIN.

[0012] As a further optimization of the present invention, the return spring is provided with a movable shaft in the middle, one end of the movable shaft is fixedly connected to the pressure sensor, and the other end slides into the inside of the bushing.

[0013] As a further optimization of the present invention, multiple bushings and conductive blocks are provided, and the bushings form conductive parts when they are sleeved on the outside of the conductive blocks. The multiple conductive parts are connected end to end in sequence and connected in series with the power supply and current sensor to form a closed loop; an alarm module is also included.

[0014] As a further optimization of the present invention, the guide rod includes segment A and segment B, and there is a gap between segment A and segment B. A magnetic block is embedded in segment B facing segment A, and the magnetic block attracts segment A.

[0015] As a further optimization of the present invention, one end of the insert shaft into the connector is flexibly configured.

[0016] The beneficial effects of this invention are as follows: 1. The defective product detection device for automotive wiring harness testing described in this invention judges bending defects by the fitting state of the insert shaft and the pin, and at the same time detects pin removal defects by utilizing the positional relationship between the continuity detection mechanism and the insertion mechanism and the on / off state of the closed circuit. This solves the problem that traditional equipment cannot detect bending defects simultaneously, greatly improves the comprehensiveness of the detection, and prevents defective products from flowing into subsequent processes.

[0017] 2. The defective product detection device for automotive wiring harness testing described in this invention can polish the oxide layer on the surface of the pin during the detection process by means of the polishing layer on the inner circumference of the receiving groove, and automatically clean the polishing debris with the help of the cleaning component, so as to realize the integration of "detection-repair-cleaning", reduce individual processing steps, and reduce production costs.

[0025] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0026] Example 1 like Figure 1 , Figure 2 and Figure 4 As shown in the embodiment of the present invention, a defective product detection device for automotive wiring harness testing includes a housing 1 and a fixture 2. The housing 1 is provided with an insertion mechanism 3 for inserting into the connector 4 to detect the pins. The insertion mechanism 3 includes a shaft 31 for applying force to the pin. The insertion end of the shaft 31 is provided with a receiving groove 3101 for detecting the flatness of the pin, so as to determine that it is in a non-bent state when it is fully fitted on the pin. The housing 1 is equipped with a continuity detection mechanism 5 that cooperates with the insertion mechanism 3; The positional status between the continuity detection mechanism 5 and the insertion mechanism 3 is used to detect the presence of PIN retraction and PIN bending.

[0027] Fixture 2 is used to fix the automotive wiring harness connector 4 to be tested, and housing 1 provides the mounting base for each mechanism. The insertion shaft 31 of the insertion mechanism 3 can extend into the connector 4, and its receiving groove 3101 at the insertion end is adapted to the PIN: if the receiving groove 3101 can be completely fitted onto the PIN, it indicates that the PIN is not bent; if it cannot be completely fitted, it is determined that the PIN is bent. At the same time, the continuity detection mechanism 5 and the insertion mechanism 3 cooperate through relative position: when the PIN is retracted, the positional relationship between the insertion shaft 31 and the continuity detection mechanism 5 is abnormal, thereby simultaneously detecting the PIN retraction defect, realizing the simultaneous detection of PIN bending and PIN retraction, solving the problem that traditional devices cannot detect bending defects, and improving the comprehensiveness of the detection. like Figure 4As shown, the insertion mechanism 3 also includes a movable seat 32, a linear driver 33, and a return component. The movable seat 32 is slidably disposed in the housing 1 and is driven by the linear driver 33. The insertion shaft 31 is slidably disposed on the movable seat 32 and is connected to the movable seat 32 through the return component. When the receiving groove 3101 is fully fitted on the PIN pin and is driven by the linear driver 33 to perform PIN removal detection, if there is PIN removal, the insertion shaft 31 cannot finally conduct with the continuity detection mechanism 5.

[0028] The linear actuator 33 drives the movable seat 32 to slide within the housing 1, causing the insert shaft 31, which is slidably mounted on the movable seat 32, to move toward the connector 4. The insert shaft 31 is connected to the movable seat 32 via a return member and can slide relative to the movable seat 32. As the receiving groove 3101 is gradually fitted onto the PIN, the linear actuator 33 continues to drive to apply a pushing force to the PIN for PIN removal detection. If the PIN is secure (no PIN removal), the insert shaft 31 is connected to the continuity detection mechanism 5. If there is PIN removal, the PIN position is offset, and the insert shaft 31 cannot ultimately connect with the continuity detection mechanism 5. The detection is automated through the linear actuator 33, and the return member ensures that the insert shaft 31 can be reset after being subjected to force.

[0029] like Figure 4 As shown, the return component includes a return spring 34 and a connecting block 35. The connecting block 35 is fixedly mounted on the insert shaft 31 and connected to the movable seat 32 through the return spring 34.

[0030] The connecting block 35 is fixedly mounted on the insert shaft 31 and connected to the moving seat 32 via the return spring 34. When the insert shaft 31 is subjected to the reaction force of the PIN pin during the testing process, the connecting block 35 slides relative to the moving seat 32 with the insert shaft 31 and stretches the return spring 34. After the test is completed, the return spring 34 releases its elastic potential energy, pushing the connecting block 35 and the insert shaft 31 back to their initial positions, providing stable reset power for the insert shaft 31, ensuring that it can accurately return to its initial position after each test, and guaranteeing the repeatability and stability of subsequent tests.

[0031] like Figure 4 As shown, further, a polished layer 36 is embedded on the inner circumference of the receiving groove 3101.

[0032] The inner circumference of the receiving groove 3101 of the insert 31 is inlaid with a polishing layer 36. When the receiving groove 3101 covers the PIN and moves with the moving seat 32, the polishing layer 36 is in close contact with the surface of the PIN. The oxide layer on the surface of the PIN is polished by relative sliding. The finishing process is completed while the PIN condition is detected, which is beneficial to the subsequent connection and transmission effect.

[0033] like Figure 4 As shown, the interior of the receiving groove 3101 is equipped with a cleaning component; The cleaning component includes a top block 37, a return spring 38, bristles 39, and a guide rod 310. The top block 37 is located inside the receiving groove 3101 and is connected to the inner wall of the receiving groove 3101 through the return spring 38. The guide rod 310 is located in the middle of the return spring 38, with one end fixedly connected to the top block 37 and the other end sliding out of the insertion shaft 31 and fixedly connected to a conductive block 311. The bristles 39 are assembled on the outer periphery of the top block 37 to clean the polishing layer 36.

[0034] When the pin enters the receiving groove 3101, it pushes the top block 37 to compress the return spring 38. The guide rod 310 slides into the insertion shaft 31 synchronously with the top block 37. When the pin exits the receiving groove 3101, the return spring 38 resets and pushes the top block 37 back. The bristles 39 on the outer periphery of the top block 37 contact the polishing layer 36 on the inner periphery of the receiving groove 3101 to clean the polishing debris remaining on the surface of the polishing layer 36. The debris on the polishing layer 36 is automatically cleaned to facilitate reuse.

[0035] like Figure 4 and Figure 6 As shown, the guide rod 310 includes section A 310A and section B 310B, and there is a gap between section A 310A and section B 310B. A magnetic block 312 is embedded in section B 310B facing section A 310A, and the magnetic block 312 attracts section A 310A.

[0036] Segment A 310A is fixedly connected to conductive block 311, and segment B 310B is fixedly connected to top block 37. Due to the gap between segment A 310A and segment B 310B, when the insert shaft 31 is fully fitted onto the PIN, conductive block 311 extends into bushing 51 to conduct electricity. When the end of the PIN is bent not near segment B 310B, conductive block 311 cannot extend into bushing 51 to conduct electricity. When the end of the PIN is bent not near segment B 310B, conductive block 311 extends into bushing 51 to act on pressure sensor 52.

[0037] like Figure 3 and Figure 4 As shown, the continuity detection mechanism 5 includes a bushing 51, a pressure sensor 52, and a return spring 53. The bushing 51 is fixedly mounted on the movable seat 32 and is correspondingly arranged with the insert shaft 31. One end of the bushing 51 facing the insert shaft 31 has a through groove adapted to the conductive block 311. The pressure sensor 52 is slidably mounted inside the through groove. One end of the return spring 53 is connected to the inner wall of the through groove, and the other end is connected to the pressure sensor 52. The pressure sensor 52 is used for pressure detection when the receiving groove 3101 is not completely fitted onto the PIN.

[0038] The bushing 51 of the continuity detection mechanism 5 is fixed on the movable seat 32 and corresponds to the insert shaft 31. Its through groove is adapted to the insert shaft 31. When the PIN is bent and the receiving groove 3101 cannot be fully fitted, the bushing 51 moves continuously. Since the insert shaft 31 cannot move, the bushing 51 is gradually fitted onto the outside of the insert shaft 31. The insert shaft 31 touches the pressure sensor 52 in the through groove of the bushing 51 and pushes the pressure sensor 52 to compress the return spring 53. After the pressure sensor 52 detects the pressure signal, it determines that the PIN has a bending defect. If the PIN is normal, the bushing 51 is fitted onto the insert shaft 31 and does not trigger the pressure sensor 52. The bending state of the PIN is accurately identified by the pressure signal, which makes up for the limitation of judging by only the fitting of the receiving groove 3101 and improves the sensitivity of bending detection.

[0039] Furthermore, the return spring 53 has a moving shaft 54 ​​in the middle. One end of the moving shaft 54 ​​is fixedly connected to the pressure sensor 52, and the other end slides into the inside of the bushing 51.

[0040] When the pressure sensor 52 is pushed by the insert shaft 31, the moving shaft 54 ​​moves along the sliding path inside the bushing 51, providing guidance for the movement of the pressure sensor 52. When the pressure disappears, the return spring 53 drives the pressure sensor 52 to reset, and the moving shaft 54 ​​moves back synchronously, ensuring that the pressure sensor 52 accurately returns to its initial position, limiting the movement trajectory of the pressure sensor 52, avoiding pressure detection errors caused by force deviation, and ensuring the stability of bending detection.

[0041] Example 2 Based on Example 1, such as Figure 4 and Figure 5 As shown, multiple bushings 51 and conductive blocks 311 are provided. When the bushing 51 is sleeved on the outside of the conductive block 311, it forms a conductive part. Multiple conductive parts are connected end to end in sequence and connected in series with the power supply and current sensor to form a closed loop. The current sensor is connected to the control module, the control module is connected to the warning module, and the control module is connected to the pressure sensor 52.

[0042] Multiple bushings 51 correspond one-to-one with multiple insert shafts 31. When the bushing 51 is fitted onto the outside of the insert shaft 31, it forms a conductive part. After the multiple conductive parts are connected end to end, they are connected in series with the power supply module and the current sensor to form a closed loop. When the PIN is not bent and there is no PIN removal, the insert shaft 31 and the bushing 51 cooperate normally through the conductive block 311, the loop is connected, and the warning module indicates normal operation. When there is bending or PIN removal, the insert shaft 31 and the bushing 51 cannot cooperate normally, the loop cannot be connected, and the warning module indicates abnormal operation.

[0043] Specifically, the warning module is a buzzer or a display.

[0044] The end of the insert shaft 31 that is inserted into the connector 4 is flexible.

[0045] When the insert shaft 31 extends into the connector 4 and contacts the PIN, the flexible end detects the force applied to the PIN by the insert shaft 31 during continuous insertion.

[0046] Working principle: Workpiece fixing and initial preparation: The automotive wiring harness connector 4 to be tested is limited by the fixture 2; The movement of insertion mechanism 3 and the alignment of the pins: When the linear driver 33 of the insertion mechanism 3 is activated, it drives the moving seat 32 to slide inside the housing 1, which in turn drives the insertion shaft 31, which is slidably set on the moving seat 32, to move closer to the insertion piece 4. The insertion shaft 31 is connected to the moving seat 32 through the return piece. The connecting block 35 is fixed on the insertion shaft 31. The two ends of the return spring 34 are connected to the connecting block 35 and the moving seat 32 respectively, ensuring that the insertion shaft 31 can slide flexibly relative to the moving seat 32 and avoid rigid collision.

[0047] Pin bending test: Segment A 310A is fixedly connected to conductive block 311, and segment B 310B is fixedly connected to top block 37. Due to the gap between segment A 310A and segment B 310B, when the insert shaft 31 is fully fitted onto the PIN, conductive block 311 extends into bushing 51 to conduct electricity. When the end of the PIN is bent not near segment B 310B, conductive block 311 cannot extend into bushing 51 to conduct electricity. When the end of the PIN is bent not near segment B 310B, conductive block 311 extends into bushing 51 to act on pressure sensor 52.

[0048] PIN pin removal PIN detection: After the receiving slot 3101 is fully fitted with the pin, the linear driver 33 continues to drive the moving seat 32 to apply a pushing force to the pin for pin removal detection. If the pin is secure (no pin is ejected), the insert shaft 31 slides relative to the moving seat 32 under the reaction force of the pin, and the return spring 34 is stretched. At the same time, the conductive block 311 on the insert shaft 31 moves with the insert shaft 31 and enters the through groove of the bushing 51. The bushing 51 is fitted on the outside of the conductive block 311 to form a conductive part. After multiple conductive parts are connected end to end, they are connected in series with the power supply module to form a closed loop. When the loop is connected, the control module detects the path through the current sensor and processes the pressure data to determine whether it is normal. If the PIN is loose or falls off, the PIN is pushed out by the insert shaft 31, the insert shaft 31 cannot slide relative to the moving seat 32, the conductive block 311 cannot enter the through groove of the bushing 51 to form a conductive part, the circuit is broken, indicating that there is a PIN removal defect.

[0049] Polishing and cleaning: Grinding: The grinding layer 36 on the inner circumference of the receiving groove 3101 comes into contact with and rubs against the surface of the pin during the pin fitting process, removing the oxide layer, burrs and other defects on the surface of the pin, and improving the smoothness of the pin. Cleaning: During testing, the PIN pushes the top block 37 in the receiving groove 3101, the top block 37 compresses the reset spring 38, the guide rod 310 moves with the top block 37 and drives the conductive block 311 to extend out of the insertion shaft 31; after the test is completed, the PIN exits the receiving groove 3101, the reset spring 38 resets and pushes the top block 37 back, the bristles 39 on the outer periphery of the top block 37 contact the polishing layer 36, and clean the residual debris from polishing.

[0050] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
