[0002] A wire harness is a bundle of wires of different specifications and colors that is bundled together using insulating materials. Wire harnesses are characterized by their integrity and reliability, ensuring that electrical equipment can operate under the harshest conditions. They are used for data transmission in electrical equipment, facilitating subsequent installation and maintenance by staff. Therefore, they are widely used in many electrical fields. During the manufacturing process, the conductivity of the wire harness needs to be inspected to ensure that the produced wire harnesses are usable.
[0003] Existing testing devices determine wire harness continuity by inserting the wire harness plug into a testing head connected to a computer terminal. After testing, the wire harness plug needs to be manually unplugged, and the wire harnesses are then placed in designated areas for qualified or unqualified workpieces. This process is highly reliant on manual labor, and for large-scale wire harness quality inspection, significant manpower is required. Furthermore, the insertion and removal processes vary due to human factors; either the insertion is incomplete or the removal is laborious, affecting the testing progress. Additionally, the high labor intensity makes this a low-efficiency production line for mass wire harness testing, failing to meet operational requirements. Utility Model Content
[0004] This utility model addresses the technical problems existing in the above-mentioned cable harness continuity testing process by proposing a cable harness continuity testing fixture that is reasonably designed, simple in structure, easy to process, and integrates functions such as workpiece input, clamping and insertion / removal, and workpiece output. On the one hand, it can replace manual labor in completing the continuity testing of cable harnesses, reducing labor intensity and saving labor costs. On the other hand, the investment in mechanical equipment can improve the automation level of production and processing to a certain extent, especially for testing large batches of workpieces, which can significantly improve the work process, enhance the practicality of the device, and meet the needs of users.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0015] Examples, such as Figures 1-5As shown, a cable harness continuity testing fixture includes a housing 1. A feeding conveyor belt 2 is located on the upper right side of the housing 1, and a discharging conveyor belt 3 is located on the upper left side of the housing 1. The feeding conveyor belt 2 can receive the workpieces to be processed, thus inputting them, and discharging the workpieces after testing, ensuring smooth workpiece transport. A support platform 4 is located between the feeding conveyor belt 2 and the discharging conveyor belt 3. A longitudinal screw moving mechanism 5 is located above the support platform 4, which can move the testing cable strip 8 to different positions to accommodate cable harness plugs of different specifications and sizes. A longitudinal shifting frame 6 is located at the moving end of the longitudinal screw moving mechanism 5. A testing box 7 is located above the longitudinal shifting frame 6. The testing cable strip 8 is located on the longitudinal shifting frame 6 on one side of the testing box 7. The testing cable strip 8 is a conventional cable strip used for existing cable harness testing and is electrically connected to the testing box 7. The testing box 7 is also a conventional technical means for testing the continuity of cable harnesses in the prior art. The specific working principle and operation method will not be elaborated further. A support frame 9 is provided on the rear side of the housing 1. A horizontal moving component 10 is provided on the support frame 9, which can drive the clamping mechanism 14 to move and adjust horizontally to complete the clamping of the workpiece and insert it into the detection line 8. At the same time, it can also remove the detected workpiece and output it outward, realizing convenient loading and unloading of workpieces and improving the practicality of the device. A vertical lifting mechanism 11 is provided on the moving end of the horizontal moving component 10. A carrier frame 12 is provided on the moving end of the vertical lifting mechanism 11. A longitudinal moving adjustment mechanism 13 is provided on the carrier frame 12, which can ensure that the clamping mechanism 14 can complete the insertion or removal of the wire harness, ensuring the smooth progress of the detection work. A clamping mechanism 14 is provided on the moving end of the longitudinal moving adjustment mechanism 13, which can not only clamp the workpiece in an adaptive manner, but also rotate and turn the end of the workpiece so that the end of the wire harness is arranged perpendicular to the detection line 8, ensuring the smooth realization of subsequent insertion and removal work and improving the work process. In the above process: the feeding conveyor belt 2 and the discharging conveyor belt 3 can, on the one hand, receive the workpieces to be processed, realizing the input of the workpieces, and on the other hand, output the workpieces that have been inspected, ensuring the smoothness of the workpiece conveying process. The longitudinal lead screw moving mechanism 5 can drive the inspection cable tray 8 to be placed in different positions to adapt to wire harness plugs of different specifications and sizes. The transverse moving component 10 can drive the clamping mechanism 14 to move and adjust laterally, completing the clamping of the workpiece and inserting the wire onto the inspection cable tray 8. At the same time, it can also unplug the inspected workpiece and output it, realizing convenient loading and unloading of workpieces and improving the practicality of the equipment. The longitudinal moving adjustment mechanism 13 can ensure that the clamping mechanism 14 completes the operation of the workpieces. The insertion or removal of paired wire harnesses ensures the smooth progress of the testing work. The clamping mechanism 14 not only clamps the workpiece appropriately but also rotates the end of the workpiece, ensuring the wire harness end is perpendicular to the testing cable tray 8. This ensures smooth subsequent insertion and removal, improving the work process. This device is rationally designed, simple in structure, and easy to manufacture. It integrates functions such as wire harness workpiece input, clamping, insertion / removal, and workpiece output. On the one hand, it can replace manual labor in conducting continuity testing of wire harnesses, reducing labor intensity and saving labor costs. On the other hand, the investment in mechanical equipment can improve the automation level of production and processing to a certain extent, especially for testing large quantities of workpieces, significantly improving the work process, enhancing the practicality of the device, and meeting usage requirements.
[0016] To facilitate convenient repositioning of the clamping mechanism 14 and enable the device to perform workpiece loading, unloading, and conveying functions, the lateral movement assembly 10 includes rotating wheels 101 located at both ends of the outer side of the support frame 9. A synchronous belt 102 is mounted on each of the two rotating wheels 101. A lateral slide bar 103 is mounted on the support frame 9 below the synchronous belt 102, and a lateral slider 104 is mounted on the lateral slide bar 103. A connecting plate 105 connected to the synchronous belt 102 is mounted on the lateral slider 104. Two sets of lateral sliders 104 are provided, each connected to one of the vertical lifting mechanisms 11. Specifically, a motor is mounted on the outer side of the support frame 9 corresponding to one of the rotating wheels 101, with its output end connected to the rotating wheel 101. The motor controls the rotation of the rotating wheel 101, driving the synchronous belt 102 for conveying. The connecting plate 105 is used to connect the lateral slider 104. The slider 104 is connected to the synchronous belt 102. The distance between the two transverse sliders 104 corresponds to the distance between the two conveyor belts. When the transverse moving component 10 is running, the rotation of the rotating wheel 101 can drive the synchronous belt 102 to convey relative to the transverse slider 103 and drive the transverse slider 104 to move and adjust. For the clamping mechanism 14 located on the right, it can clamp the workpiece on the feeding conveyor belt 2 and, driven by the transverse moving component 10, insert the clamped workpiece into the detection line to place the wire harness. For the clamping mechanism 14 located on the left, it can clamp and remove the wire harness placed on the detection line 8. When the transverse moving component 10 moves, the workpiece can be placed onto the discharge conveyor belt 3. The above-mentioned device and equipment components integrate the functions of workpiece clamping and feeding and clamping output, which greatly improves the smoothness and convenience of the workpiece production and processing process and meets the usage requirements.
[0017] To further improve the rationality of the device setup, the vertical lifting mechanism 11 includes a vertical plate 111 connected to the horizontal slider 104. A vertical slide bar 112 is provided on the front side of the vertical plate 111, a vertical slider 113 is provided on the vertical slide bar 112, and a vertical moving plate 114 is provided on the vertical slider 113. A vertical drive cylinder 115 is provided above the vertical plate 111, and its output end is connected to the vertical moving plate 114. Specifically, the vertical drive cylinder 115 is controlled to operate, driving the vertical moving plate 114 and the vertical slider 113 to adjust their vertical position relative to the vertical slide bar 112. This allows the clamping mechanism 14 and the clamped workpiece to be adjusted in the vertical direction, enabling the workpiece to be placed at different detection positions on the detection line 8, ensuring the smooth progress of the detection work. It not only allows the workpiece to be conveniently inserted into the detection line 8, but also allows the workpiece to be removed after detection, improving the work process.
[0018] To ensure the smooth implementation of the insertion operation, the longitudinal movement adjustment mechanism 13 includes a carrier plate 131 connected to the carrier frame 12. A longitudinal slide bar 132 is provided on the carrier plate 131, and a longitudinal slider 133 is provided on the longitudinal slide bar 132. A longitudinal movement plate 134 is provided above the longitudinal slider 133. A longitudinal movement drive cylinder 135 is provided on one side of the carrier plate 131, and its output end is connected to the longitudinal movement plate 134. Specifically, when the longitudinal movement drive cylinder 135 is running, it can act on the longitudinal movement plate 134 to adjust its movement relative to the longitudinal slide bar 132. When the clamping mechanism 14 clamps the workpiece so that its end is arranged longitudinally, the longitudinal movement plate 134 is controlled to move, and the clamping mechanism 14 is driven to move closer to the detection line 8, so that the end of the workpiece cooperates with the detection line 8, ensuring the smooth progress of the continuity detection operation and meeting the usage requirements.
[0019] To facilitate workpiece clamping, the clamping mechanism 14 includes a crossbeam 141 positioned above the longitudinal transfer plate 134. A limiting slide bar 142 is mounted on the crossbeam 141. A rotating shaft 143 is located at the geometric center of the limiting slide bar 142. A rotating plate 144 is mounted on the rotating shaft 143. Connecting rods 145 are mounted on both sides of the rotating plate 144. An adjusting plate 146 is mounted on the limiting slide bar 142 located outside the rotating shaft 143 and connected to one end of the connecting rods 145. A rotating mechanism is located below the adjusting plate 146. The rotary clamping cylinder 147 is specifically described as follows: A cylinder is installed on the longitudinal moving plate 134 located on one side of the crossbeam 141. Its output end is connected to one side of the adjusting plate 146. For workpieces of different sizes, the cylinder is controlled to act on the adjusting plate 146, causing the adjusting plate 146 to move relative to the limiting slide bar 142. By using the established connecting rod 145 and rotating plate 144, the left and right adjusting plates 146 can be driven to move relative to or towards each other in the lateral direction on the limiting slide bar 142 to adapt to different sizes of workpieces. The device clamps workpieces of specific dimensions, greatly improving its functionality. When the rotary clamping cylinder 147 moves to the appropriate position, it clamps the workpiece laterally. When inspecting the wire harness end, the output end of the rotary clamping cylinder 147 is rotated, adjusting the wire harness end from a horizontal position to a vertical position. This allows the wire harness end to be placed perpendicular to the inspection wire rack 8. The longitudinal movement adjustment mechanism 13 then moves the wire harness end onto the inspection wire rack 8, ensuring the inspection is performed. This operation is performed by the clamping mechanism 14 on the right side. The clamping mechanism 14 on the left side clamps and removes the wire harness from the inspection wire rack 8, placing the removed workpiece onto the discharge conveyor belt 3 for convenient output after inspection. The operation is simple and convenient, with high functionality, meeting various usage needs and greatly improving the practicality of the device.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
