[0057] Wire harnesses are crucial structures for connecting electrical components, and their functionality directly impacts the normal operation of equipment. During wire harness production, various functional tests are required, including traditional tests such as continuity testing, high-frequency testing, and high-voltage testing. Traditional testing methods largely rely on manual inspection, using multiple testing devices on an assembly line to sequentially insert and remove wire harnesses, testing their functionality after establishing electrical connections with the corresponding devices. This method is labor-intensive and unreliable; manual insertion and removal of connectors can easily affect test accuracy and lead to missed detections.

[0058] This invention proposes a wire harness testing workbench 100.

[0059] Please see Figure 1 , Figure 2 and 4As shown, in one embodiment of the present invention, the wire harness testing workbench 100 can simultaneously perform multiple tests on the wire harness. Specifically, multiple testing stations are provided on the workbench 11 in the middle of the frame 1. The multiple testing stations are evenly spaced around the vertical axis of the workbench 11, which can simultaneously meet the simultaneous testing needs of multiple testing stations, effectively improving testing efficiency in actual testing. Specifically, multiple testing structures 2 are provided at the upward end of the frame 1 corresponding to the multiple testing stations. Each testing structure 2 includes multiple testing devices. It should be noted that each testing device corresponds to one performance test of the wire harness. Before testing, the wire harnesses to be tested are first fixed on carrier components 4. Each carrier component 4 can hold multiple wire harnesses. During testing, multiple carrier components 4 are respectively mounted on multiple fixing components 3 for fixation. Each drive structure 5 drives the corresponding fixing component 3 to move. During the movement of multiple fixing components 3, the multiple wire harnesses on the carrier components 4 are sequentially connected to multiple testing devices, thereby performing various performance tests on the multiple wire harnesses on the carrier components 4. It can be imagined that during this process, multiple wire harnesses are fixed on multiple carrier components 4 for testing, and multiple testing stations are set up to work simultaneously. Therefore, in this embodiment, compared with traditional testing methods and testing equipment, its testing efficiency is greatly improved. Furthermore, corresponding loading and unloading structures can be equipped for automatic loading and unloading, such as using a robotic arm structure to replace traditional loading operations, thereby further improving the testing efficiency and effect of the entire equipment.

[0060] like Figures 5 to 7 As shown, the carrier component 4 mainly includes a base portion 41 and an inner core portion 42 slidably mounted on the base portion 41. The hollow portion 411 at the end of the base portion 41 is provided corresponding to the bottom of the inner core portion 42. The inner core portion 42 is provided with multiple mounting features for fixing the wire harness. Specifically, multiple recessed mounting portions 421 are evenly spaced along the axial direction on the peripheral wall of the inner core portion 42. The connection ends of the two ends of the test wire harness can be fixed on the fixing structure 43 on the mounting portion 421. After fixing, the two connection ends of the wire harness are set vertically upward. One test wire harness can be fixed on each mounting portion 421. During the test, the test of multiple wire harnesses can be completed simultaneously.

[0061] Among them, such as Figure 3 and Figure 6As shown, a plurality of guide plates 413 are provided on the base portion 41, and a guide portion 423 is formed between two adjacent mounting portions 421. The plurality of guide portions 423 respectively guide the movement of the inner core portion 42 in the vertical direction. One end of the driving structure 5 drives the inner core portion 42 to move on the base portion 41 through the hollow portion 411, so that the two connecting ends of the wire harness on the fixing structure 43 are respectively connected to the plurality of testing devices, thereby completing the corresponding performance test of the wire harness. In this process, in order to enable the inner core portion 42 to return to its original position on the base portion 41, a return spring 424 is provided between one end of the guide portion 423 and the base portion 41. When one end of the driving structure 5 is separated from the inner core portion 42, the inner core portion 42 can return to its original position on the base portion 41. In addition, a corresponding winding structure 44 is provided on the mounting part 421. The winding structure 44 and the mounting part 421 form a detachable connection. When the test wire harness is long, the wire harness can be pre-wound onto the winding structure 44, and then the two ends of the wire harness can be fixed by the fixing structure 43. Thus, during the test, the excessive length of the wire harness can be effectively avoided from affecting the movement of the fixing member 3.

[0062] It is conceivable that the multiple mounting portions 421 on the inner core 42 can be equipped with pre-used prompting elements, such as indicator lights of different colors. When the wire harness fixed at the current position fails the test, it can display the corresponding color so that the relevant defective products can be classified in the future, which can greatly improve the efficiency of classification.

[0063] At the same time, such as Figure 7 As shown, in order to effectively reduce the overall weight of the inner core 42, the inner core 42 can be made of plastic material, and a recessed hole 422 is provided on the end face of the inner core 42 away from the base portion 41, thereby effectively reducing the overall weight of the inner core 42.

[0064] like Figure 3 and Figure 6As shown, the fixing structure 43 includes two receiving blocks 431 and two rotating pressing blocks 432. Specifically, both receiving blocks 431 are installed at the mounting part 421, and each of the two receiving blocks 431 has a corresponding recessed groove 4311 corresponding to the shape of the wire harness connection end. The two rotating pressing blocks 432 are respectively installed on the two receiving blocks 431. In actual use, the two connection ends of the test wire harness are placed upwards in the two recessed grooves 4311 for fixing, and then the rotating pressing blocks 432 are rotated to press down and fix one side of the wire harness. It can be imagined that the shape of the recessed groove 4311 can be set according to the shape of the connection end of the test wire harness. Furthermore, in order to achieve a better fixing effect, a corresponding snap-fit ​​structure can be set between the receiving blocks 431 and the rotating pressing blocks 432. The above structures are all existing conventional structures and will not be described in detail here.

[0065] like Figure 3 and Figure 6 As shown, the winding structure mainly includes a winding roller and a limiting structure disposed at the mounting part 421. The winding roller has two outward protrusions 4411 at both ends. The limiting structure mainly includes two locking heads 442. Each locking head 442 has an inclined portion corresponding to both the inner and outer sides of the mounting part 421. The mounting part 421 has two locking holes 443. The two locking heads 442 are slidably installed in the two locking holes 443, and one end of each locking head 442 is connected to the mounting part 421 by a locking spring 444. After the wire harness is wound onto the take-up roller 441, the two protrusions 4411 corresponding to the inclined portions of the two locking heads 442 are pushed inward toward the mounting portion 421, thereby causing the two locking heads 442 to slide in the locking hole 443. At this time, the locking spring 444 is compressed, ultimately limiting the two protrusions 4411 to one side of the locking hole 443 corresponding to the mounting portion 421. After the test is completed, pulling the take-up roller outward can move the locking heads 442, thereby releasing the limitation on the protrusions 4411. The above structure makes fixing and releasing the take-up roller relatively simple, and can also assist in the winding and fixing of longer wire harnesses, which is beneficial for dealing with different test wire harness specifications.

[0066] like Figure 3 and Figure 4As shown, the workbench 11 has multiple circular holes 112 corresponding to multiple test stations, and multiple fixing members 3 are respectively provided inside the multiple circular holes 112. Specifically, the fixing member 3 mainly includes a rotating disk 31 and a cylinder 32 installed on the rotating disk 31. The rotating disk 31 is rotatably installed inside the circular hole 112, and the two can be connected by a bearing. A mounting hole 311 is provided on the downward end of the rotating disk 31. One end of the drive structure 5 is connected to the mounting hole 311, which can drive the rotating disk 31 to rotate. The connecting end of the drive structure 5 can be connected to the inner core 42 through the mounting hole 311, thereby driving the inner core 42 to move. When the base part 41 is placed, the multiple protruding parts 412 are aligned with the multiple slots 313 on the annular part 312, and then the base part 41 is fixed to the upper surface of the rotating disk 31. In order to enhance the fixing effect, the cylinder 32 drives the pressure head 321 to move, so that the end face of the pressure head 321 with the beveled part 322 moves to the upper surface of the base part 41, thereby limiting and fixing the base part 41. During the movement of the inner core part 42, the base part 41 can also maintain a good fixed state. During this process, the setting of the beveled part 322 can also prevent the pressure head 321 from making hard contact with the base part 41 during the movement when the carrier part 4 is not properly placed, thereby preventing damage to the base part 41.

[0067] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the workbench 11 is configured as a double-layer structure, which includes a first plate 111 and a second plate 113. The first plate 111 and the second plate 113 are connected by multiple connecting shafts 115. Specifically, the second plate 113 is fixedly connected to the frame 1, and multiple rotating disks 31 are mounted on the first plate 111.

[0068] The second plate 113 is provided with multiple mounting brackets 114 corresponding to the multiple rotating disks 31 for mounting multiple drive structures 5. Specifically, the drive structure 5 includes a sleeve shaft structure 51, a motor component 52, and a push rod component 53. The sleeve shaft structure 51 is configured as a double-layer structure, wherein the rotating shaft 511 is sleeved on the outside of the top shaft component 512. When the motor component 52 is working, it drives the rotating shaft 511 to rotate through the transmission structure, thereby realizing the rotation of the rotating disk 31 within the circular hole 112. During the rotation of the rotating disk 31, the correspondence between multiple wire harnesses and multiple testing devices can be switched, thereby enabling multiple tests of multiple wire harnesses on one rotating disk 31. In the actual docking process, after the rotating disk 31 rotates to a suitable position, that is, when the connection ends of multiple testing devices correspond vertically to the two connection ends of multiple wire harnesses, the push rod 53 drives the top shaft 512 to move upward within the inner cavity of the rotating shaft 511. Its upward end contacts the bottom end of the inner core 42, and drives... The inner core 42 moves on the base 41, thereby aligning the end connectors of multiple wire harnesses with the connectors of multiple testing devices to form a conductive state. At this time, multiple wire harnesses can be tested by multiple testing devices. After the current performance test of the corresponding wire harness is completed, the motor 52 drives the rotating disk 31 to rotate at a certain angle, thereby driving the inner core 42 to move again through the push rod 53. Thus, through the coordinated movement of the motor 52 and the push rod 53, the testing and switching of multiple performance of multiple wire harnesses can be realized.

[0069] Above the frame 1 is a test piece mounting plate 12. On the test piece mounting plate 12, there are corresponding test head mounting frames 121 for multiple test stations. The connection ends of multiple test devices corresponding to the same test station are fixed on the corresponding test head mounting frames 121.

[0070] Specifically, such as Figure 1 , Figure 2 and Figure 8As shown, the test head mounting bracket 121 is provided with multiple fixing parts 1212. The number of the multiple fixing parts 1212 corresponds to the number and position of the multiple mounting parts 421 on the inner core 42. In this embodiment, four are provided, and their corresponding vertical positions correspond to the multiple mounting parts 421 in the vertical direction. The multiple test devices include a continuity test device 21, a high voltage test device 22, a high frequency test device 23, and a concentric test device 24. The test connection ends of the continuity test device 21, the high voltage test device 22, the high frequency test device 23, and the concentric test device 24 are respectively installed on the multiple fixing parts 1212. During the process of the push rod 53 driving the inner core 42 to move in the vertical direction, the connection ends of the multiple test devices can be connected to the connection ends of the multiple wire harnesses, thereby simultaneously performing different performance tests on the multiple wire harnesses.

[0071] To improve the accuracy of the docking between the testing equipment and the wire harness ends, a corresponding visual inspection device 6 is also provided. The visual inspection device 6 includes multiple mounting brackets 62, multiple inspection lenses 63, and an inspection device 61. The inspection lenses 63 on the mounting brackets 62 can monitor the insertion positions of multiple wire harness connection ends on the multiple inner cores 42 in real time and feed back the relevant image information to the inspection device 61. When the end position of the corresponding wire harness deviates, an early warning can be issued, and the docking action of the corresponding drive structure 5 can be stopped. Furthermore, to obtain better image information, in this embodiment, an arc-shaped clearance groove 1211 is provided on the end of the test head mounting bracket 121 corresponding to the inspection lens 63.

[0072] There is a space below the frame 1 for installing the control cabinet 14, and a corresponding protective structure can be set below the frame 1 to improve the safety of the entire equipment operation.

[0073] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
