Description

Technical Field

[0001] This utility model relates to the field of wire harness testing technology, specifically to a wire harness testing bench assembly with an adjustable bracket and a quick-change connector module. Background Technology

[0002] In the automotive, consumer electronics, and industrial control industries, wire harnesses serve as the "nerve vessels" of various electrical devices, undertaking the core functions of signal transmission and power supply. Their connection reliability and conductivity directly determine the operational stability of end products. Therefore, the quality inspection process in wire harness production is crucial, and the wire harness testing bench, as the core equipment for this process, has become a key factor affecting a company's production pace and product yield due to its testing efficiency, adaptability, and ease of operation.

[0003] Currently, most mainstream wire harness testing benches on the market adopt a "fixed module + single adapter" design, which has gradually revealed many technical pain points in practical applications, making it difficult to meet the production needs of modern manufacturing industries for small batches and multiple varieties. Specific problems are as follows: The core testing component (i.e., the plug-in module) of the existing wire harness testing bench is usually fixed to the bench base by rigid connection methods such as bolts and screws. When it is necessary to test wire harnesses of different specifications (such as different number of terminals, spacing, and interface types), it is necessary to use tools such as wrenches and screwdrivers to disassemble the fixing parts one by one and then re-align and install the new module, which is very cumbersome. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a wire harness testing bench assembly with an adjustable bracket and a quick-change connector module.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a wire harness testing bench assembly with an adjustable bracket and a quick-change plug-in module, including a fixed installation mechanism, wherein a plug-in module mechanism is slidably arranged inside the fixed installation mechanism, and the plug-in module mechanism is used to test the wire harness; The two side walls inside the fixed installation mechanism are also provided with quick-release structures. The two quick-release structures are used to fix the plug-in module mechanism, thereby realizing the quick replacement of the plug-in module mechanism. The top of the fixed installation mechanism is also provided with a support mechanism, which is used to separate the wire bundle ends.

[0006] The fixed installation mechanism provides a stable assembly base for each component, the plug-in module mechanism enables wire harness testing, the quick-release structure simplifies the replacement process of the plug-in module mechanism, and the bracket mechanism prevents the wire harness ends from becoming messy, thus ensuring the stability and orderliness of the testing process as a whole.

[0007] Furthermore, the fixed installation mechanism includes a base, the top of which has an installation cavity, and two slide rails are fixedly installed inside the installation cavity. Installation grooves are provided on both sides of the inner side wall of the base.

[0008] The base provides overall support, the mounting cavity provides space for the plug-in module mechanism, the slide rail provides guidance for the sliding assembly of the plug-in module mechanism, and the mounting slot provides a dedicated installation position for the quick-release structure, ensuring that the assembly position of each component is accurate and the structure is stable.

[0009] Furthermore, the plug-in module mechanism includes an integrated base, the top of which is provided with several plug-in modules, the bottom of which has two sliding grooves, and the two side walls of which are provided with snap-fit ​​grooves.

[0010] The integrated base integrates multiple plug-in modules to achieve centralized testing. The slide groove can cooperate with the slide rail of the fixed installation mechanism to achieve sliding assembly, and the snap-fit ​​groove can cooperate with the quick-release structure to achieve fixation, providing a structural foundation for the disassembly, assembly and testing functions of the plug-in module mechanism.

[0011] Furthermore, the quick-release structure includes a first fixing ring, a second fixing ring on the outer side of the first fixing ring, a mounting plate between the first fixing ring and the second fixing ring, a support spring fixed between the mounting plate and the second fixing ring, a locking rod on the inner side wall of the mounting plate, a connecting rod on the outer side wall of the mounting plate, and a pull plate on the outer side wall of the connecting rod.

[0012] The first and second fixing rings provide sliding guidance and limit for the mounting plate, the support spring can drive the mounting plate to reset, the locking rod can fix the plug-in module mechanism, and the connecting rod and the pull plate can conveniently control the movement of the mounting plate, thereby realizing tool-free quick unlocking and locking, simplifying the replacement operation of the plug-in module mechanism.

[0013] Furthermore, the two sliding grooves at the bottom of the integrated base are slidably connected to the two sliding rails, the integrated base is slidably installed inside the mounting cavity, and after the sliding installation is completed, the locking rod is inserted into the snap-fit ​​groove to form a fixation.

[0014] The sliding fit between the slide rail and the slide groove ensures smooth assembly and precise positioning of the integrated base. The insertion fit between the locking rod and the snap-fit ​​groove can stably fix the integrated base in the installation cavity, preventing the integrated base from shifting during the testing process and affecting the testing accuracy.

[0015] Furthermore, the first fixing ring and the second fixing ring are respectively fixedly installed on both sides inside the mounting groove. The mounting plate is slidably installed between the second fixing ring and the first fixing ring. The pulling plate is installed on the outside of the base. By pulling the pulling plate, the connecting rod and the mounting plate move synchronously, thereby driving the locking rod to move away from the snap-fit ​​groove, and squeezing the support spring in the process.

[0016] By fixing the first and second fixing rings in the mounting groove, the quick-release structure is assembled stably. The pull plate on the outside makes it easy for the operator to apply force. The pulling operation can simultaneously move the mounting plate and compress the support spring, quickly releasing the lock and providing a convenient operation path for disassembling the plug-in module mechanism.

[0017] Furthermore, the support mechanism includes two support seats, one of which has a lead screw inside and the other has a linear optical axis inside. Both the lead screw and the linear optical axis are provided with sliding blocks. A servo motor is provided at the input end of the lead screw and at the top of the support seat. A separator is provided between the two sliding blocks.

[0018] Two support seats provide mounting support for the lead screw and the linear optical axis respectively. The servo motor can drive the lead screw to rotate, which in turn drives the sliding block to move smoothly along the linear optical axis, thereby adjusting the position of the separator seat. The separator position can be flexibly adjusted according to the number and distribution requirements of the wire bundle ends, ensuring that the wire bundle ends are separated in an orderly manner and avoiding mutual entanglement that may affect the detection operation.

[0019] The beneficial effects of this utility model are as follows: Through the design of the quick-release structure and the sliding rail-slide groove combination, tool-free rapid replacement of the plug-in module is achieved: pulling the pull plate on the outside of the base allows the connecting rod to drive the mounting plate to compress the support spring, causing the locking rod to simultaneously disengage from the snap-fit ​​groove of the integrated base; at this time, the integrated base can slide smoothly along the slide rail of the fixed mounting mechanism, easily completing the removal and installation of the new module. After releasing the pull plate, the restoring force of the support spring can push the locking rod to automatically snap into the snap-fit ​​groove of the new integrated base, forming a reliable fixation. The entire process does not require disassembling bolts, avoiding the problems of mounting hole wear and positioning reference offset caused by traditional disassembly and assembly, significantly shortening the module replacement time, and effectively adapting to the rapid production changeover needs of modern manufacturing industries with multiple types of wire harnesses.

[0020] The support mechanism allows for precise separation and positioning of wire bundle ends: two support seats are respectively equipped with a lead screw and a linear optical axis. When the servo motor drives the lead screw to rotate, the sliding block can drive the separator seat to move smoothly along the linear optical axis, thereby adjusting the position of the separator seat according to the number and length of the wire bundles, orderly separating the wire bundle ends and preventing the wires from tangling. This not only eliminates the step of manually organizing the wire bundles, reducing labor costs, but also prevents problems such as incorrect terminal insertion and misjudgment caused by wire tangling. At the same time, it avoids terminal deformation caused by wire tension, protects the original performance of the wire bundle, and reduces material loss. Attached Figure Description

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0026] Example 1 Figure 1 This is a structural diagram of the main body of this utility model. Figure 2 This is a structural diagram of the plug-in module mechanism of this utility model. Figure 3 This is a schematic diagram of the quick-release structure of this utility model. Figure 4 This is a cross-sectional schematic diagram of the present invention, as shown below. Figures 1 to 4 As shown, the device includes a fixed mounting mechanism 10, inside which a plug-in module mechanism 20 is slidably disposed, which is used to detect the wire harness; quick-release structures 30 are also provided on both sides of the fixed mounting mechanism 10, which are used to fix the plug-in module mechanism 20, thereby realizing quick replacement of the plug-in module mechanism 20; a bracket mechanism 40 is also provided on the top of the fixed mounting mechanism 10, which is used to separate the wire harness ends.

[0027] During testing, the plug-in module mechanism 20 slides within the fixed installation mechanism 10 to adapt to the wire harness docking requirements to complete the testing; the quick-release structure 30 can quickly release the fixation of the plug-in module mechanism 20 through locking / unlocking actions, allowing it to slide out, and can also quickly fix it after the new module is installed, improving replacement efficiency; the bracket mechanism 40 orderly separates the wire harness ends, avoiding wire harness tangling and facilitating testing operations.

[0028] like Figure 2 As shown, the fixed installation mechanism 10 includes a base 101, an installation cavity 102 is provided on the top of the base 101, two slide rails 103 are fixedly installed inside the installation cavity 102, and installation grooves 104 are provided on both sides of the inner side wall of the base 101.

[0029] The base 101 provides a stable mounting platform for other mechanisms; the mounting cavity 102 accommodates the plug-in module mechanism 20 and allows it to slide; the slide rail 103 provides precise guidance for the sliding of the plug-in module mechanism 20; the mounting slot 104 provides dedicated mounting space for the quick-release structure 30, ensuring that the quick-release structure 30 is securely assembled to reliably fix and unlock the plug-in module mechanism 20.

[0030] The plug-in module mechanism 20 includes an integrated base 201. The top of the integrated base 201 is provided with several plug-in modules 202. The bottom of the integrated base 201 has two sliding grooves 203. The two side walls of the integrated base 201 are provided with snap-fit ​​grooves 204.

[0031] The integrated base 201 integrates and carries multiple plug-in modules 202, enabling simultaneous detection of multiple wire harnesses or wire harnesses of different types; the bottom slide groove 203 cooperates with the slide rail 103 of the fixed installation mechanism 10, allowing the integrated base 201 to slide smoothly along the slide rail 103 in the installation cavity 102 to adjust the docking position; the side wall snap-fit ​​grooves 204 cooperate with the locking components of the quick-release structure 30, and when the locking components are inserted, the integrated base 201 is fixed, ensuring stability during detection.

[0032] Such as 3 and Figure 4 As shown, the quick-release structure 30 includes a first fixing ring 301, a second fixing ring 302 on the outer side of the first fixing ring 301, a mounting plate 303 between the first fixing ring 301 and the second fixing ring 302, a support spring 305 fixed between the mounting plate 303 and the second fixing ring 302, a locking rod 304 on the inner side wall of the mounting plate 303, a connecting rod 306 on the outer side wall of the mounting plate 303, and a pulling plate 307 on the outer side wall of the connecting rod 306.

[0033] The first and second fixing rings 302 provide sliding guidance and limiting space for the mounting plate 303, allowing the mounting plate 303 to slide smoothly. The support spring 305 is compressed and stores energy when the mounting plate 303 moves toward the second fixing ring 302. When the external force disappears, it pushes the mounting plate 303 back toward the first fixing ring 301. The inner locking rod 304 cooperates with the snap-fit ​​groove 204 of the plug-in module mechanism 20 to achieve fixation. The outer connecting rod 306 connects the mounting plate 303 and the pull plate 307. When the operator pulls the pull plate 307, the mounting plate 303 slides through the connecting rod 306, thereby controlling the extension and retraction of the locking rod 304 to complete the unlocking and locking of the plug-in module mechanism 20.

[0034] The two sliding grooves 203 at the bottom of the integrated base 201 are slidably connected to the two slide rails 103. The integrated base 201 is slidably installed inside the mounting cavity 102. After the sliding installation is completed, the locking rod 304 is inserted into the snap-fit ​​groove 204 to form a fixed position.

[0035] The bottom groove 203 of the integrated base 201 cooperates with the slide rail 103 of the fixed installation mechanism 10 to form a sliding connection, so that the integrated base 201 can slide along the slide rail 103 in the installation cavity 102, which is convenient to push to the designated position or pull out. When the integrated base 201 is installed in place, the locking rod 304 of the quick release structure 30 is precisely inserted into the snap-fit ​​groove 204 on both sides of the integrated base 201 under the elastic force of the support spring 305, so as to stably fix the integrated base 201 in the installation cavity 102, prevent displacement due to wire harness insertion and extraction force during testing, and ensure testing accuracy.

[0036] The first fixing ring 301 and the second fixing ring 302 are respectively fixedly installed on both sides inside the mounting groove 104. The mounting plate 303 is slidably installed between the second fixing ring 302 and the first fixing ring 301. The pulling plate 307 is installed on the outside of the base 101. By pulling the pulling plate 307, the connecting rod 306 and the mounting plate 303 move synchronously, thereby driving the locking rod 304 to move away from the snap-fit ​​groove 204, and in the process, the support spring 305 is squeezed.

[0037] The first and second fixing rings 302 are fixed on both sides of the mounting groove 104, providing a stable guiding range for the sliding of the mounting plate 303; the mounting plate 303 slides freely between the second and first fixing rings 301; the pull plate 307 is installed on the outside of the base 101 for easy application of force, and when pulled, it drives the connecting rod 306 and the mounting plate 303 to slide towards the second fixing ring 302. During this process, the mounting plate 303 compresses the support spring 305, and at the same time, the inner locking rod 304 moves with the mounting plate 303 and disengages from the snap-fit ​​groove 204, thereby unlocking the plug-in module mechanism 20 and facilitating its disassembly or replacement.

[0038] Example 2 Based on the above embodiments, this embodiment also makes the following improvements, such as... Figure 1 and Figure 2 As shown, the support mechanism 40 includes two support seats 401. One support seat 401 has a lead screw 402 inside, and the other support seat 401 has a linear optical axis inside. Both the lead screw 402 and the linear optical axis are provided with sliding blocks 403. A servo motor 404 is provided at the input end of the lead screw 402 and at the top of the support seat 401. A separator seat 405 is provided between the two sliding blocks 403.

[0039] Two support seats 401 provide mounting support for the lead screw 402 and the linear optical axis, respectively. The servo motor 404 drives the lead screw 402 to rotate. Since the lead screw 402 is threadedly engaged with the corresponding sliding block 403, the rotation of the lead screw 402 is converted into the linear movement of the sliding block 403 along the lead screw 402. The linear optical axis provides linear guidance for the other sliding block 403, ensuring the linearity of the movement of the sliding block 403. The synchronous movement of the two sliding blocks 403 drives the separator seat 405 to move. The position of the separator seat 405 can be flexibly adjusted according to the number and distribution of the wire ends, so as to achieve orderly separation of the wire ends, avoid tangling, and facilitate wire harness docking and inspection.

[0040] It should be noted that the electrical equipment and components mentioned above are all programmed and controlled using existing PLC controllers. Since these are mature technologies, they will not be described in detail here.

[0041] Workflow Step 1, Install the plug-in module: Align the bottom slide groove 203 of the integrated base 201 of the plug-in module mechanism 20 with the slide rail 103 of the fixed mounting mechanism 10, and smoothly push the integrated base 201 into the mounting cavity 102 along the slide rail 103. When the integrated base 201 is fully inserted into the mounting cavity 102, the compressed support spring 305 in the quick-release structure 30 releases its elasticity, pushing the mounting plate 303 to move inward, and driving the locking rod 304 to accurately insert into the snap-fit ​​grooves 204 on both sides of the integrated base 201, thus completing the fixing of the plug-in module mechanism 20 and ensuring no displacement during testing.

[0042] Step 2, Adjustment of the support mechanism 40: Based on the number, distribution and length of the wire ends of the wire harness to be tested, start the servo motor 404 of the support mechanism 40. The servo motor 404 drives the lead screw 402 to rotate, so that the sliding block 403 on the lead screw 402 moves linearly along the lead screw 402. At the same time, the sliding block 403 on the linear optical axis moves synchronously with it, driving the separator 405 between the two sliding blocks 403 to adjust to a suitable position, so as to orderly separate the wire ends and avoid them from getting tangled together.

[0043] Step 3, wire harness testing operation: Insert the terminals of the wire harness to be tested into the corresponding plug-in module 202 at the top of the plug-in module mechanism 20. The plug-in module 202 completes the performance testing of the wire harness, such as conductivity and insulation. During the testing process, the locking rod 304 of the quick-release structure 30 continuously clamps the locking slot 204 to ensure the stability of the integrated base 201; the partition seat 405 of the bracket mechanism 40 maintains the orderly state of the wire harness ends to avoid pulling of the wire harness or incorrect insertion of terminals.

[0044] Step 4, Replacement of the plug-in module (if necessary): When it is necessary to test different specifications of wire harnesses, pull the pull plate 307 of the quick-release structure 30 outward, and drive the mounting plate 303 to move outward through the connecting rod 306, compress the support spring 305, so that the locking rod 304 disengages from the snap-fit ​​groove 204, release the fixation of the integrated base 201, slide the old integrated base 201 out of the mounting cavity 102 along the slide rail 103, and then push the new plug-in module mechanism 20 into the mounting cavity 102 and fix it in the manner of step 1, to complete the quick replacement.

[0045] Step 5, Reset after testing: After the test is completed, disconnect the wiring harness terminal. If you need to test again, you can repeat steps 2-3. If the test is finished, you can reset the separator 405 to the initial position through the servo motor 404 to prepare for the next test.
