Description

Technical Field

[0001] This application relates to the field of wire harness processing technology, and more specifically, to a terminal height detection mechanism. Background Technology

[0002] In industrial production, terminals, as key components for electrical connections, directly impact the reliability of connections and the overall performance of equipment due to the accuracy of their height dimensions. Especially in high-end manufacturing sectors such as automotive, aerospace, and precision electronics, height deviations after terminal riveting or assembly can lead to poor contact, signal transmission failures, or even equipment malfunctions. Therefore, accurate measurement of terminal height is crucial for ensuring product quality. Currently, commonly used methods for terminal height measurement in the industry include manual caliper measurement, visual inspection equipment, and contact sensor detection. Among these, visual inspection equipment, due to its high efficiency, has found some application in mass production scenarios.

[0003] Existing visual inspection equipment relies on optical imaging principles, which are easily affected by factors such as terminal surface reflection, color differences, changes in ambient lighting, and complex background interference. This leads to inaccurate edge extraction of the inspection image, resulting in height measurement errors. In particular, for terminals with complex surface structures or those with minor protrusions or depressions, visual inspection often struggles to accurately capture their actual height information, and the stability and reliability of the inspection results need to be improved.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figures 1-5 A terminal height detection mechanism includes a base plate 1, a Y-axis linear module 2 fixedly connected to the top of the base plate 1, a placement seat 15 slidably connected to the top of the Y-axis linear module 2, and a height detection component provided above the placement seat 15.

[0029] The height detection assembly includes a displacement detection component and a clamping component;

[0030] The displacement detection component includes a sensor body 6 and a detection head 5, and the clamping assembly includes a gripper 4 for fixing the terminal and a reference block 11 that cooperates with the detection head 5.

[0031] First, the operator or an external robotic arm places the riveted part to be inspected on the reference block 11. At this time, the gripper 4 starts and clamps and fixes the riveted part from both sides. The clamping force of the gripper 4 can be adjusted according to the material and structural characteristics of the riveted part (usually 5-30N) to ensure that the riveted part will not loosen or shift during the inspection process, providing a stable foundation for subsequent multi-point inspection.

[0032] Next, the device's displacement drive system begins to operate according to the preset program. The Y-axis linear module 2 starts first, driving the placement seat 15 and the fixed riveting parts on it to move along the Y-axis direction. At the same time, the slider 14 slides along the first slide rail 3, cooperating with the movement of the Y-axis linear module 2 to adjust the position of the riveting parts, so that the first riveting point to be detected on the riveting parts is within the detection range of the detection head 5.

[0033] Subsequently, the displacement cylinder 8 pushes the fixing plate 13 and the detection head 5 to move horizontally, so that the detection head 5 is precisely aligned with the top of the riveting point. Then, the connecting seat 12 slides along the second slide rail 7, driving the sensor body 6 and the detection head 5 to move slowly downward (the feed speed is generally controlled at 0.5-2mm / s). When the lower end face of the detection head 5 contacts the top of the riveting point, the displacement sensing element built into the sensor body 6 will instantly capture the contact signal. At this time, the displacement cylinder 8 and the second slide rail 7 immediately stop moving, and the sensor body 6 synchronously records the current position parameters of the detection head 5, repeating the above process of contact, signal capture, and position parameter recording.

[0034] Following this process, the equipment sequentially inspects all preset riveting points. After each point is inspected, the relevant data is transmitted in real time to an external control system (existing technology, not shown in the diagram). After acquiring the position parameters of all riveting points, the control system combines this with the reference parameter of the detection surface height of the reference block 11 to calculate the actual height value of each riveting point.

[0035] Finally, the external control system (existing technology, not shown in the diagram) analyzes all calculated height values ​​to determine whether the height of each riveting point is within the preset acceptable range. If the height of all points meets the standard, the riveted part is deemed acceptable; if any point does not meet the standard, it is deemed unacceptable. After the inspection is completed, the gripper 4 is released, the riveted part is released, and components such as the Y-axis linear module 2, slider 14, displacement cylinder 8, and connecting seat 12 are reset, awaiting the inspection process of the next riveted part.

[0036] Reference Figures 1-3 The top of the base plate 1 is provided with a first slide rail 3, and a slider 14 is slidably fitted on the outer wall of the first slide rail 3. A gripper cylinder 9 is fixedly connected to one end of the slider 14. The gripper 4 is fixedly connected to the gripper cylinder 9. A connecting plate 10 is fixedly connected to the front end of the slider 14. One end of the reference block 11 is fixedly connected to the connecting plate 10.

[0037] Reference Figures 1-4 The top of the placement seat 15 is provided with a second slide rail 7, and the outer wall of the second slide rail 7 is slidably fitted with a connecting seat 12. The front side of the connecting seat 12 is provided with a displacement cylinder 8, and the output end of the displacement cylinder 8 is connected to a fixing plate 13.

[0038] Reference Figures 3-4 The fixing plate 13 is provided with mounting holes for mounting the sensor body 6. The sensor body 6 is fixed in the mounting holes. The detection head 5 and the detection surface of the reference block 11 are aligned in the vertical direction. The vertical distance between the detection head 5 and the detection surface of the reference block 11 can be adjusted synchronously as the slider 14 slides along the first slide rail 3.

[0039] Working principle: The operator or external robotic arm places the riveted part to be inspected on the reference block 11. The gripper 4 then starts to clamp and fix the riveted part from both sides. The clamping force can be adjusted within the range of 5-30N according to the material and structural characteristics of the riveted part, ensuring that the riveted part does not loosen or shift during the inspection process, providing a stable foundation for subsequent multi-point inspection.

[0040] Next, the displacement drive system operates according to the preset program. The Y-axis linear module 2 is started, driving the placement seat 15 and the riveting parts on it to move along the Y-axis. At the same time, the slider 14 slides along the first slide rail 3. The two work together to adjust the position of the riveting parts so that the first riveting point to be detected enters the detection range of the detection head 5.

[0041] Subsequently, the displacement cylinder 8 pushes the fixing plate 13 and the detection head 5 to move horizontally, so that the detection head 5 is precisely aligned with the top of the riveting point. The connecting seat 12 then slides along the second slide rail 7, driving the sensor body 6 and the detection head 5 to move slowly downward at a speed of 0.5-2mm / s. When the lower end face of the detection head 5 contacts the top of the riveting point, the displacement sensing element built into the sensor body 6 captures the contact signal. At this time, the relevant components stop moving, and the sensor body 6 records the current position parameters of the detection head 5.

[0042] Afterward, the equipment repeats the above-mentioned process of contact, signal capture, and parameter recording, sequentially detecting all preset riveting points. Upon completion of the detection of each point, the data is transmitted to the external control system in real time. After acquiring all position parameters, the control system calculates the actual height value of each riveting point based on the detection surface height reference of reference block 11, and analyzes whether these height values ​​are within the preset acceptable range. If all meet the standard, the riveted part is deemed acceptable; otherwise, it is deemed unacceptable.

[0043] After the inspection is completed, the gripper 4 releases the riveted parts, and the Y-axis linear module 2, slider 14, displacement cylinder 8, connecting seat 12 and other components are reset, waiting for the inspection of the next riveted part.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
