[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

The application of the detection mechanism 10 can refer to the existing public technology without limitation and duplication. It also includes:

[0032] A transition box 2, the transition box 2 is fixed to the top of the test bench 1, a side plate 3 is fixed to the front and rear sides of the transition box 2, a support driving assembly is installed between the two side plates 3 on the left and right sides of the transition box 2, the support driving assembly is used to separate the multiple wire harnesses 16, and the two support driving assemblies are used to drive the two ends of the wire harness 16 away from each other;

The two ends of the driving shaft are rotatably connected to the two side plates 3. A plurality of conveying rollers are damped and rotatably installed on the driving shaft. The conveying roller adopts an arc-shaped concave structure in the middle. A motor 5 for driving the driving shaft of a conveying roller member 14 at the outer end is also fixed on the side plate 3. By driving a conveying roller member 14 to rotate, the driving of the wiring harness 16 can be achieved to meet the use requirements.

[0039] In order to improve the stability of the side plate 3 , support rods 4 are fixed to the lower sides of both ends of the side plate 3 , and the lower ends of the support rods 4 are fixed on the detection platform 1 .

[0040] An auxiliary plate 33 is provided between two adjacent conveying roller members 14 and on the outer side of the conveying roller member 14 at the outer end. The auxiliary plate 33 is matched with the contour clearance of the conveying roller member 14, and the two ends of the auxiliary plate 33 are fixedly connected to the two side plates 3 accordingly. The auxiliary plate 33 can block the wire harness 16 to prevent the wire harness 16 from falling into the gap between the two conveying roller members 14.

[0041] like Figure 1-5 As shown, as a preferred embodiment of the present invention, the positioning and clamping assembly includes a vertical telescopic cylinder 6, a bearing frame 11, a guide rod 12, an adjusting nut 13, an inverted U-shaped frame 18, a support shaft 19, a pressure wheel 20, a stop head 21, a spring 22, a movable plate 32 and a switch positioning member, the end of the side plate 3 is provided with a bearing frame 11, both sides of the bearing frame 11 are fixed with a vertical telescopic cylinder 6, the lower end of the vertical telescopic cylinder 6 is fixed to the side plate 3, the upper lower side of the bearing frame 11 is provided with an inverted U-shaped frame 18, a support shaft 19 is fixed on the inverted U-shaped frame 18, and a plurality of conveying rollers 14 at the outer end are rotatably installed on the support shaft 19. The roller vertically corresponds to the pressure wheel 20, and the pressure wheel 20 adopts a middle arc-shaped concave structure. A plurality of guide rods 12 corresponding to the pressure wheel 20 are fixed on the top of the inverted U-shaped frame 18, and the guide rods 12 also slide through the upper part of the supporting frame 11. An adjusting nut 13 is threadedly connected to the guide rod 12 on the upper side of the supporting frame 11, and a spring 22 is sleeved on the guide rod 12 between the supporting frame 11 and the inverted U-shaped frame 18. A stop head 21 for braking the pressure wheel 20 is also fixed to the lower end of the guide rod 12, and the stop head 21 is located between the horizontal part of the inverted U-shaped frame 18 and the pressure wheel 20. The stop head 21 adopts a middle arc-shaped concave structure, which can better and reliably brake the pressure wheel 20.

[0042] The lower part of the carrier frame 11 is horizontally slidably provided with a plurality of switch positioning members corresponding one to one with the conveying rollers of the conveying roller member 14. A movable plate 32 is also provided on the side of the carrier frame 11 away from the conveying roller member 14. The movable plate 32 is fixedly connected to the plurality of switch positioning members. A horizontal telescopic cylinder 2 34 is also fixedly provided in the middle of the lower part of the carrier frame 11. The output end of the horizontal telescopic cylinder 2 34 is fixedly connected to the movable plate 32. When the switch positioning members installed on the same carrier frame 11 are all triggered, the motor 5 of the support drive assembly corresponding to the carrier frame 11 stops working.

[0043] The test plug-in assembly includes a horizontal telescopic cylinder 7, a fixed block 8 and a fixed plate 9. A horizontal telescopic cylinder 7 is also fixed to the outer side of the lower part of the carrier frame 11. The output end of the horizontal telescopic cylinder 7 is fixed to the fixed block 8. The end of the fixed block 8 is fixed to the fixed plate 9. The fixed plate 9 is fixed to the side of the detection mechanism 10. The horizontal telescopic cylinder 7 is used to drive the detection mechanism 10 to move horizontally close to or away from the conveying roller 14.

[0044] Preferably, the detection socket 23 installed on the detection mechanism 10 corresponds one-to-one to the conveying roller of the conveying roller member 14 , so that the detection socket 23 can be plugged into the connector 29 accordingly.

[0045] Preferably, the supporting frame 11 includes an inclined plate 26, a vertical plate 27 and a horizontal plate 28, and an inclined plate 26 is fixed to the front and rear sides of the bottom of the horizontal plate 28 respectively, and a vertical plate 27 is fixed between the ends of the two inclined plates 26 away from the horizontal plate 28; the vertical telescopic cylinder 16 is fixed to the lower sides of both ends of the horizontal plate 28, and the guide rod 12 slides through the horizontal plate 28; the switch positioning member is slidably installed on the vertical plate 27, and a horizontal telescopic cylinder 17 is fixed to the two ends of the outer side of the vertical plate 27 respectively.

[0046] Preferably, in order to improve the translational stability of the detection mechanism 10, a guide rail 30 is fixed to the lower side of the detection mechanism 10, and a slider 31 is slidably provided on the guide rail 30, and a vertical telescopic cylinder 2 17 is fixed to the lower side of the slider 31, and the lower end of the vertical telescopic cylinder 2 17 is fixed on the detection platform 1, and the vertical telescopic cylinder 2 17 and the vertical telescopic cylinder 1 6 perform telescopic actions synchronously, that is, to ensure the consistency of the detection mechanism 10 and the supporting frame 11, avoid the detection socket 23 from touching the supporting frame 11, and improve reliability.

[0047] Preferably, the switch positioning member includes a switch seat 24 and a trigger head 25, the trigger head 25 is elastically and telescopically mounted on the switch seat 24, the switch seat 24 is slidably connected to the vertical plate 27, the movable plate 32 is fixedly connected to the switch seat 24, and the triggering of the switch positioning member is linked to the motor 5 in a conventional arrangement without limitation or elaboration.

[0048] Preferably, when the pressure wheel 20 abuts against the surface of the wiring harness 16 on the conveying roller member 14, the stop head 21 and the pressure wheel 20 are in a separated state, and the pressure wheel 20 can rotate, at this time, the switch positioning member also corresponds horizontally one by one with the wiring harness 16 on the conveying roller member 14; when the stop head 21 abuts against the pressure wheel 20, the pressure wheel 20 cannot rotate, and at this time, the detection socket 23 corresponds horizontally one by one with the wiring harness 16 on the conveying roller member 14.

[0049] When in use, firstly, the switch positioning piece on the vertical plate 27 is controlled to correspond to the connector 29 of the wiring harness 16 through the vertical telescopic cylinder 16. At this time, the pressure wheel 20 presses the wiring harness 16, and cooperates with the rotation of the conveying roller 14 to drive the wiring harness 16 to move. When the connector 29 of the wiring harness 16 triggers the switch positioning piece, the corresponding conveying roller on the conveying roller 14 rotates, that is, the corresponding wiring harness 16 cannot be transmitted, and the remaining conveying rollers continue to rotate and wait for all the wiring harnesses 16 to be triggered by the switch positioning piece, thereby completing the driven movement and positioning of all the wiring harnesses 16.

[0050] The limited movable plate 32 and horizontal telescopic cylinder 2 34 are used to drive the movable plate 32 to move by the horizontal telescopic cylinder 2 34 after all the wiring harnesses 16 are positioned, so that the switch positioning member is separated from the connector 29, ensuring the smooth descent of the carrier frame 11 and improving reliability.

[0051] When the wiring harness 16 is positioned and the switch positioning piece is separated from the connector 29, the vertical telescopic cylinder 6 contracts. When the stop head 21 abuts against the pressure wheel 20, the pressure wheel 20 cannot rotate. At this time, the detection socket 23 and the wiring harness 16 on the conveying roller 14 correspond horizontally one by one, which ensures the stability of the wiring harness 16 and moves the detection socket 23 into place. Then, the detection mechanism 10 is driven to move by the horizontal telescopic cylinder 7, so that the detection socket 23 and the connector 29 can be plugged in.

[0052] In addition, the gap between the stopper 21 and the pressure wheel 20 is the distance from the rotation state to the fixed state of the pressure wheel 20, which enables the pressure wheel 20 and the conveying roller 14 to cooperate with the wire harnesses 16 of different thicknesses for transmission; the position of the adjusting nut 13 can also be adjusted as needed to change the initial distance between the horizontal plate 28 and the inverted U-shaped frame 18; when the stopper 21 abuts against the pressure wheel 20 and brakes the pressure wheel 20, the vertical telescopic cylinder 6 can be continued to be controlled to shrink, and the spring 22 is continued to be compressed at this time, which can further ensure that the detection socket 23 corresponds to the connector 29 of the wire harness 16 of different models, which is flexible and reliable. It should be noted that when the stopper 21 abuts against the pressure wheel 20 and brakes the pressure wheel 20, the vertical telescopic cylinder 6 is continued to be controlled to shrink, and the spring 22 is continued to be compressed. Generally, the difference in models is small, and the wire harness 16 will not be compressed and deformed, which can meet the needs of flexible use.

[0053] like Figure 1As shown, as a preferred embodiment of the present invention, the top of the transition box 2 is also provided with a wire harness groove 15 corresponding to the conveying roller of the conveying roller member 14, and both ends of the wire harness groove 15 extend to the conveying roller members 14 on both sides. The wire harness groove 15 is used to store the middle part of the wire harness 16 and to separate and position the wire harness 16, thereby improving the separation efficiency.

[0054] The above-mentioned embodiment of the present invention provides a new energy cable harness detection device, which controls the position of the harness by positioning and clamping components to ensure the accuracy of the test. From the separation, positioning, clamping to the test plugging of the harness 16, the entire process is highly automated, which reduces manual intervention and improves work efficiency. In addition, through the adjustable pressure wheel 20 and the conveying roller 14, it can adapt to the testing requirements of harnesses 16 of different specifications; the spring 22 is cleverly used to achieve the transition and connection of the test process, which improves the efficiency of the harness 16 detection, and also has good adaptability and stability.

[0055] There is no specific limitation on the control, model and circuit connection of each component, which can be flexibly set in practical application. The circuits, electronic components and modules involved are all prior art, and those skilled in the art can fully implement them. It is needless to say that the content protected by the present invention does not involve improvements to software and methods.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
