[0002] As a kind of special equipment, the harness assembly detection bench aims to accurately assess the performance of harness assembly in multiple industries (such as automobiles, aircraft, electric vehicle control systems and home appliance industries, etc.). However, the current market harness assembly detection benches face some challenges in automation and flexibility.

[0003] The operation process often combines manual and mechanical detection, resulting in limited automation. In actual use, a large amount of manual placement, fixation and detection result reading of the harness is relied on, which not only increases labor cost, but also limits the improvement of detection efficiency.

[0004] Although the detection bench is equipped with mechanical detection equipment, the automation level of these equipment is generally not high, and it is difficult to completely realize automatic operation. For different models or configurations of the harness, manual adjustment of the parameters or position of the detection equipment may be required, further increasing the complexity and time cost of operation.

[0005] The variety, specification and connection method of the harness have diversity, making the existing detection bench have limitations in adaptability. For some special harness, specific detection equipment and unique operation method may be required, which undoubtedly increases the complexity and difficulty of detection. SUMMARY

[0025] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0026] As Figs. 1 to 4 shown, we show a wire harness assembly detection table, which mainly consists of the following parts: rack 1, support frame 9, mechanical hand 10, placement clamp 11, and the object for detection-wire harness terminal 8.

[0027] The support frame 9 is carefully placed beside the rack 1, and the mechanical hand 10 is firmly installed on the support frame 9. At the free end of the mechanical hand 10, we placed the placement clamp 11 specially used for clamping the wire harness terminal 8.

[0028] Let's focus on the top of the rack 1, where a workbench 2 is set up, and a stand 3 is installed at the corner of the workbench 2. The end of the stand 3 is installed with a visual detection head 4, which is mainly responsible for monitoring the entire detection process.

[0029] Above the workbench 2, we designed multiple slide rail assemblies 5. The sliding seat of these slide rail assemblies 5 is installed with a connecting seat 6, which is connected with a screw rod through threads, and then connected with a clamping seat 7. The clamping seat 7 can be flexibly adjusted in height through the screw rod, ensuring that the wire harness terminal 8 can accurately face the socket of the plug-in head detection assembly 13.

[0030] The workbench 2 is also installed with a track 12, on which a movable connector detection assembly 13 is installed. This connector detection assembly 13 moves on the track 12 through a sliding block, and it includes a connector, a hydraulic cylinder and a detection module. The connector is electrically connected with the detection module and is installed at the telescopic end of the hydraulic cylinder. When the hydraulic cylinder works, it can drive the connector to move so as to connect with the wire harness terminal 8, thereby realizing connector detection.

[0031] The slide rail assembly 5 is a ball screw assembly, which has the characteristics of high precision and high stability. The connecting seat 6 is installed on the sliding seat of the slide rail assembly 5 through bolts, ensuring the firmness of the connection.

[0032] The track 12 is perpendicular to the slide rail assembly 5, and multiple slide rail assemblies 5 are designed in parallel. Such a layout makes the entire detection table more compact and efficient.

[0033] Finally, the column 3 is installed on the workbench 2 through bolts, nuts and non-slip washers, and the visual detection head 4 is directly opposite the end of the three slide rail assemblies 5, which can clearly capture the entire process of the connection between the wire harness terminal 8 and the connector detection assembly 13, providing important visual support for detection.

[0034] Detection process: The mechanical hand 10 cooperates with the placement clamp 11. Initially, the mechanical hand 10 is positioned to the position where the wire harness terminal 8 needs to be grabbed through its control system. Then, the mechanical hand 10 starts to accurately grab the wire harness terminal 8 using the end placement clamp 11. After the wire harness terminal 8 is grabbed, the mechanical hand 10 moves according to the preset trajectory to transport the wire harness terminal 8 above the clamping seat 7.

[0035] Placement of the wire harness terminal 8: When the mechanical hand 10 transports the wire harness terminal 8 above the clamping seat 7, the placement clamp 11 is loosened to release the wire harness terminal 8. Under the action of gravity, the wire harness terminal 8 naturally falls into the clamping seat 7 and is stably fixed in position by the clamping seat 7.

[0036] Adjustment of the clamping seat 7: The height of the clamping seat 7 can be flexibly changed by adjusting the threaded connection between the connecting seat 6 and the screw rod. During this process, the operator will adjust the clamping seat 7 as needed to ensure that the wire harness terminal 8 can accurately face the connector of the connector detection assembly 13.

[0037] The detection process of the plug-in connector detection assembly 13; the plug-in connector of the plug-in connector detection assembly 13 is installed at the telescopic end of the hydraulic cylinder and is electrically connected with the detection module. When the hydraulic cylinder works, it drives the plug-in connector to move and connect with the wire harness terminal 8. During the plugging process, the detection module monitors the plugging state in real time, such as whether the plugging is in place and whether the contact is good. If abnormalities are found, such as the plugging is not in place or the contact is not good, the detection module will immediately send a signal to stop the work of the hydraulic cylinder and notify the operator to take corresponding measures.

[0038] The monitoring of the visual detection head 4; the visual detection head 4 is opposite to the end of the three slide rail assemblies 5 and can clearly shoot the whole process of the plugging of the wire harness terminal 8 and the plug-in connector detection assembly 13. Through the analysis of the shot image, the operator can further confirm the plugging state and result.

[0039] The whole detection process realizes the efficient and accurate detection of the wire harness terminal 8 through the cooperation of the mechanical hand 10, the placing clamp 11, the clamping seat 7 and the plug-in connector detection assembly 13. At the same time, the monitoring function of the visual detection head 4 provides important visual support for the detection, ensuring the reliability and accuracy of the detection result.
