Description

Technical Field

[0001] This application relates to the field of detection technology, and more specifically, to a detection device and a detection system. Background Technology

[0002] With modern industrial products (such as automotive parts and medical devices) requiring high-precision testing of parameters such as sealing and material strength, general-purpose equipment is insufficient to cover all specific scenarios. Targeted devices can provide early warnings of risks, reduce human error in testing, shorten production cycles, and reduce safety risks. In fields such as medical devices and cybersecurity, which require compliance with strict safety regulations, specialized testing devices are essential tools for compliance.

[0003] Aviation connectors (aviation plugs) are widely used in fields with high connector performance requirements due to their high reliability, strong environmental resistance, vibration resistance, and good sealing. For example, in the vacuum field, molecular pumps are mostly connected to their controllers (drivers) via aviation connectors during production. During the soldering of aviation connectors, various factors such as materials and soldering techniques can lead to incomplete solder joints. Obvious incomplete solder joints can be detected visually or with a multimeter. However, subtle incomplete solder joints are undetectable by visual inspection or multimeters. Equipment with such incomplete solder joints may not necessarily malfunction under prolonged low current or short-term high current conditions; however, problems will arise under prolonged high current conditions. This can lead to production stoppages or even fires. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a detection device and a detection system to improve the above-mentioned problems existing in the prior art.

[0005] In a first aspect, this application provides a detection device comprising: a clamping assembly, a detection assembly, an adjustment assembly, and a monitoring assembly; the clamping assembly is used to fix a workpiece to be tested; wherein the detection assembly is configured to detect a region of the workpiece to be tested; the adjustment assembly includes a connecting rod and a magnetic base; the clamping assembly and / or the detection assembly are disposed on the connecting rod, the connecting rod is disposed on the magnetic base, and the magnetic base is attracted to the plane of the workpiece to be tested; wherein the connecting rod is perpendicular to the plane of the workpiece to be tested; the monitoring assembly is communicatively connected to the detection assembly, and the monitoring assembly is configured to receive detection data from the detection assembly; wherein the detection data is used to be analyzed to obtain a detection conclusion.

[0006] In the above implementation process, by integrating the clamping component, detection component, adjustment component, and monitoring component into one unit, efficient and stable detection of the workpiece is achieved. The magnetic base can quickly adhere to the plane where the workpiece is located, and combined with the vertical positioning of the connecting rod, it ensures high alignment accuracy between the detection component and the area to be detected, while also facilitating installation and disassembly to adapt to different detection scenarios. The monitoring component receives detection data in real time, facilitating subsequent analysis and rapid conclusions, thus improving the efficiency of the detection process.

[0007] Optionally, the adjustment assembly further includes: a sliding bracket; the sliding bracket moves along the extension direction of the connecting rod; the sliding bracket includes a first connecting portion and a second connecting portion, the first connecting portion being used to connect the connecting rod, and the second connecting portion being used to fix the clamping assembly or the detection assembly.

[0008] In the above implementation process, the sliding bracket allows the clamping assembly or detection assembly to be adjusted in height along the extension direction of the connecting rod, thereby accommodating workpieces of different sizes and detection depths. Rapid positioning is achieved through the sliding engagement of the first connecting part and the connecting rod; the second connecting part can fix the clamping assembly or detection assembly as needed, enhancing the versatility and operational flexibility of the device, and further improving detection efficiency and accuracy.

[0009] Optionally, the sliding bracket further includes: a first adjustment knob and a second adjustment knob; the first adjustment knob is configured to adjust the fastening force between the sliding bracket and the connecting rod; the second adjustment knob is configured to adjust the fastening force between the clamping assembly and / or the detection assembly and the connecting rod.

[0010] In the above implementation process, the introduction of the first and second adjustment knobs enables control over the clamping forces between the sliding bracket and the connecting rod, as well as between the clamping assembly and / or the detection assembly and the connecting rod. This improves the repeatability and ease of operation of the device, reduces debugging time, and enhances detection efficiency and reliability. Optionally, the clamping assembly includes: an elastic clamping part, a clamping unit, and a quick-release structure; the elastic clamping part is disposed on the contact surface between the clamping unit and the quick-release structure; the clamping unit is connected to the adjustment assembly through the quick-release structure; wherein the specifications of the clamping unit match the workpiece to be tested.

[0011] In the above implementation process, by arranging the elastic clamping part on the contact surface between the clamping unit and the quick-release structure, a flexible buffer layer is formed, avoiding scratches, indentations, or stress concentrations caused by rigid clamping. Furthermore, elastic damping is formed between the quick-release structure and the adjustment assembly, reducing errors caused by vibration or minute displacements during testing. Simultaneously, the quick-release structure allows for rapid disassembly and replacement of the clamping unit. When the specifications of the part to be tested change, only a clamping unit with matching specifications needs to be replaced, eliminating the need for complete disassembly of the adjustment assembly. This significantly shortens changeover time and improves equipment versatility and testing efficiency.

[0012] Optionally, the quick-release structure includes: a first fixed end and an adjusting end; the first fixed end is connected to the adjusting component, and the first fixed end is configured to fix the clamping component to the adjusting component; the adjusting end includes a screw and a nut; wherein the screw and the nut cooperate to drive the clamping unit to lock and unlock.

[0013] In the above implementation process, the first fixed end is pre-connected to the adjustment component. When it is necessary to replace the clamping unit with a different specification, simply rotate the nut on the adjustment end to lock or loosen the clamping unit within seconds, avoiding the cumbersome operation caused by traditional multi-bolt disassembly and assembly. At the same time, by adjusting the screw insertion depth, the clamping force can be finely adjusted to adapt to the clamping requirements of different materials or fragile workpieces, taking into account both ease of operation and clamping reliability.

[0014] Optionally, the detection component includes: a temperature sensor and a probe bracket; the temperature sensor is mounted on the probe bracket, and the probe of the temperature sensor faces the area to be detected; the temperature sensor is configured to collect temperature data of the area to be detected of the object to be tested; the temperature sensor includes a second fixed end, and the probe bracket includes a connecting portion and an adjusting arm; the second fixed end is fixed to the connecting portion by a connector; the adjusting arm is configured to adjust the position of the temperature sensor relative to the area to be detected.

[0015] In the above implementation process, by integrating the temperature sensor onto the probe bracket and using an adjusting arm to finely adjust the sensor's position and orientation with multiple degrees of freedom, the probe is always aligned with the area to be detected and maintains optimal contact or spacing, thereby improving the accuracy of temperature measurement. The second fixed end is fixed to the connecting part using a detachable connector, which ensures the stability of the temperature sensor under high-speed or vibration conditions and allows for quick assembly and disassembly when the sensor needs to be replaced or maintained, reducing downtime.

[0016] Optionally, the detection component further includes a third adjustment knob; the third adjustment knob is configured to control the angle of the adjustment arm relative to the area to be detected.

[0017] In the above implementation process, the introduction of a third adjustment knob allows the adjustment arm to be finely adjusted around its pivot, changing the incident angle or fit of the temperature sensor probe relative to the area to be detected. This not only allows for rapid adaptation to detection scenarios with different surface curvatures, inclinations, or limited space, but also enables immediate angle correction when abnormal temperature data is detected, avoiding measurement errors caused by probe misalignment.

[0018] Optionally, the monitoring component includes an alarm unit configured to issue an alarm signal and / or shut down when the analysis results are abnormal.

[0019] In the above implementation process, the alarm unit is integrated into the monitoring component, which can receive and analyze the detection data transmitted by the detection component in real time. When the system determines that the analysis result exceeds the preset threshold or an abnormal trend occurs, the alarm unit can immediately trigger at least one of the two response mechanisms: issuing an alarm signal and automatic shutdown. Secondly, embodiments of this application provide a detection system, which includes a plurality of the aforementioned detection devices; wherein the plurality of detection devices are arranged around the workpiece to be detected.

[0020] In the above implementation process, by arranging multiple detection devices as described in the first aspect around the workpiece to be tested, the detection space is covered without blind spots. All temperature sensors work simultaneously, and the monitoring components can aggregate data from multiple points in real time. When a device causes data anomalies due to obstruction or malfunction, the data from adjacent devices can be cross-verified and the abnormal values ​​can be automatically removed, improving the overall reliability.

[0021] Optionally, the plurality of detection devices include: a first detection device, a second detection device, and a third detection device; the first detection device includes a clamping assembly for clamping the workpiece to be tested; the second detection device includes a first detection assembly and a second detection assembly; wherein a first temperature sensor in the first detection assembly faces a first detection area of ​​the workpiece to be tested, and a second temperature sensor in the second detection assembly faces a second detection area of ​​the workpiece to be tested; the third detection device includes a third detection assembly and a fourth detection assembly; wherein a third temperature sensor in the third detection assembly faces a third detection area of ​​the workpiece to be tested, and a fourth temperature sensor in the fourth detection assembly faces a fourth detection area of ​​the workpiece to be tested; wherein the first detection area, the second detection area, the third detection area, and the fourth detection area are not located at the same position on the workpiece to be tested.

[0022] In the above process, the first detection device performs the clamping task, and its clamping components are firmly attached to the workpiece reference surface by a magnetic base. The second detection device carries the first and second temperature sensors, which are aligned with the first and second areas to be detected, respectively; the third detection device carries the third and fourth temperature sensors, which are aligned with the third and fourth areas to be detected, respectively. The four areas do not overlap, and the temperature distribution scan of different positions on the workpiece can be completed in one go, eliminating the random errors of single-point measurement. When the workpiece model or detection area changes, only the second and third detection devices need to be moved or added, while the first detection device remains stationary.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. 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 the embodiments of this application.

[0027] Firstly, please refer to Figure 1 , Figure 1 The detection device provided in the embodiments of this application.

[0028] This application discloses a testing device comprising: a clamping assembly 100, a testing assembly 200, an adjusting assembly 300, and a monitoring assembly 400; the clamping assembly 100 is used to fix the workpiece to be tested; wherein, the testing assembly 200 is configured to test the area to be tested of the workpiece; the adjusting assembly 300 includes a connecting rod 310 and a magnetic base 320; the clamping assembly 100 and / or the testing assembly 200 are disposed on the connecting rod 310, the connecting rod 310 is disposed on the magnetic base 320, and the magnetic base 320 is adsorbed onto the plane of the workpiece to be tested; wherein, the connecting rod 310 is perpendicular to the plane of the workpiece to be tested; the monitoring assembly 400 is communicatively connected to the testing assembly 200, and the monitoring assembly 400 is configured to receive the testing data from the testing assembly 200; wherein, the testing data is used for analysis to obtain testing conclusions.

[0029] In the above implementation process, the clamping component 100 fixes the workpiece to be tested, ensuring its stability during testing and avoiding testing errors caused by shaking or displacement. The detection component 200 acts directly on the area to be tested to acquire key data, while the adjustment component 300, through the vertical setting of the magnetic base 320 and the connecting rod 310, achieves the positioning and support of the detection component 200 or the clamping component 100, adapting to different planes and testing angle requirements. The adsorption characteristics of the magnetic base 320 simplify the installation process, eliminating the need for additional fixing tools and improving operational efficiency. The monitoring component 400 receives and stores the testing data in real time, providing a reliable basis for subsequent analysis and ensuring the accuracy and traceability of the testing conclusions. The overall structure is compact and modular, facilitating rapid on-site deployment and repeated adjustments, and is suitable for the high-efficiency quality inspection needs in industrial scenarios.

[0030] Optionally, the adjustment assembly 300 further includes: a sliding bracket 330; the sliding bracket 330 moves along the extension direction of the connecting rod 310; the sliding bracket 330 includes a first connecting part 331 and a second connecting part 332, the first connecting part 331 is used to connect the connecting rod 310, and the second connecting part 332 is used to fix the clamping assembly 100 or the detection assembly 200.

[0031] In the above implementation process, the sliding bracket 330 enables the clamping assembly 100 or the detection assembly 200 to be adjusted vertically along the axial direction of the connecting rod 310, expanding the adaptability of the detection device. Through the sliding engagement of the first connecting part 331 and the connecting rod 310, the user or operator can quickly adjust the position of the detection assembly 200 or the clamping assembly 100 on the plane perpendicular to the workpiece to be detected according to the height of the workpiece or the depth of the detection area, without reinstallation, thus improving operational efficiency. The second connecting part 332 provides a stable interface, ensuring that the clamping or detection components remain rigidly positioned after adjustment, reducing displacement caused by gravity or external forces. This reduces repeated positioning errors and ensures the consistency and reliability of the detection data.

[0032] Optionally, the sliding bracket 330 further includes: a first adjustment knob 341 and a second adjustment knob 342; the first adjustment knob 341 is configured to adjust the fastening force between the sliding bracket 330 and the connecting rod 310; the second adjustment knob 342 is configured to adjust the fastening force between the clamping assembly 100 and / or the detection assembly 200 and the connecting rod 310.

[0033] In the above implementation process, on the one hand, the first adjustment knob 341 can be quickly locked by the operator after the sliding bracket 330 is moved to the target height, so as to prevent the height deviation caused by vibration or external force during the detection process and ensure the detection stability; on the other hand, the second adjustment knob 342 allows the orientation and posture of the clamping component 100 or the detection component 200 to be finely adjusted and locked without changing the position of the sliding bracket 330, so as to adapt to the detection needs of complex surfaces or special angles.

[0034] Optionally, the clamping assembly 100 includes: an elastic clamping part 110, a clamping unit 120, and a quick-release structure 130; the elastic clamping part 110 is disposed on the contact surface between the clamping unit 120 and the quick-release structure 130; the clamping unit 120 is connected to the adjusting assembly 300 through the quick-release structure 130; wherein the specifications of the clamping unit 120 are matched with the workpiece to be tested.

[0035] In the above implementation process, the elastic clamping part 110 forms a buffer and adaptive layer between the clamping unit 120 and the quick-release structure 130. When the clamping unit 120 clamps the workpiece to be tested, the elastic clamping part 110 can generate a slight deformation according to the surface contour of the workpiece, increasing the effective contact area, dispersing the clamping stress, and preventing indentations, scratches, or plastic deformation of thin-walled, fragile, or coated workpieces. The quick-release structure 130 realizes the locking or releasing of the clamping unit 120 and the adjustment component 300, and the clamping specification can be switched without tools, meeting the multi-model mixed-flow testing needs of the production line.

[0036] Optionally, the fixture unit 120 can be designed to be interchangeable, with its internal cavity or positioning surface customized according to the geometric features of the part to be inspected, such as V-shaped, arc-shaped, or contoured groove.

[0037] In one embodiment of this application, the clamp unit 120 can be applied to an aviation plug, also known as a plug socket, which is widely used in various electrical circuits to connect or disconnect circuits. There are several common specifications for aviation plugs; the M12 series of round aviation plugs typically has an outer diameter of 12mm, while the M23 series has an outer diameter of approximately 23mm. Rectangular aviation plugs can also be used.

[0038] Optionally, the quick-release structure 130 includes: a first fixed end 131 and an adjusting end 132; the first fixed end 131 is connected to the adjusting assembly 300, and the first fixed end 131 is configured to fix the clamping assembly 100 onto the adjusting assembly 300; the adjusting end 132 includes a screw and a nut; wherein the screw and nut cooperate to drive the clamping unit 120 to lock and unlock.

[0039] In the above implementation process, the first fixed end 131 directly forms a shape fit or keyway positioning with the adjustment component 300, ensuring that the clamping component 100 maintains micron-level positioning stability when subjected to lateral forces or vibrations. When the nut is tightened at the adjustment end 132, the screw generates axial tension, quickly pressing the clamping unit 120 onto the reference surface of the first fixed end 131; loosening it completes the release. This allows for one-handed operation in narrow production lines or equipment gaps.

[0040] In one embodiment of this application, one end of the quick-release structure 130 is fixed to the sliding bracket 330, and the other end is adjusted by turning the butterfly nut to adjust the tightness of the clamp, thereby adapting to objects of different sizes.

[0041] Optionally, an anti-loosening spring washer and a limiting groove are added to the tail of the screw to prevent position drift caused by loosening during the test.

[0042] Optionally, the standardized first fixed end 131 interface allows clamping units 120 of different specifications to share the same adjustment component 300.

[0043] In one embodiment of this application, the quality of the solder joint directly affects conductivity. If the solder joint has defects such as poor soldering, oxidation, or poor contact, it may lead to increased resistance, unstable signal transmission, or even short circuits or open circuits. Testing ensures that the solder joint is full, free of voids, and that the contact resistance meets standards. Solder joints must withstand environmental stresses such as vibration and impact. Insufficient solder joint strength may cause pins to detach or result in poor contact due to vibration. Aviation connectors are often exposed to harsh environments such as high temperatures, low temperatures, and salt spray. Insufficient solder joint sealing may lead to corrosion or leakage risks.

[0044] In this context, solder joints of varying quality exhibit different thermodynamic properties. Good solder joints have a dense internal structure, high metal content (primarily tin-lead or lead-free solder paste), and excellent bonding with component leads and pads. They possess a large heat capacity, low thermal resistance, and require more heat to raise their temperature. However, poor solder joints are filled with air or flux residue at defective areas. Air is an insulator with extremely poor thermal conductivity; cold solder joints or cracks result in an actual contact area between the solder and the leads / pads that is far smaller than the theoretical value. In other words, poor solder joints, such as cold solder joints, cracks, and voids, lead to a decrease in heat capacity, a significant increase in thermal resistance, and are more easily heated. When electrical testing cannot predict long-term reliability, temperature monitoring becomes crucial.

[0045] Optionally, the detection assembly 200 includes: a temperature sensor 210 and a probe holder 220; the temperature sensor 210 is mounted on the probe holder 220, and the probe of the temperature sensor 210 faces the area to be detected; the temperature sensor 210 is configured to collect temperature data of the area to be detected of the object to be tested; the temperature sensor 210 includes a second fixed end, and the probe holder 220 includes a connecting portion 221 and an adjusting arm 222; the second fixed end is fixed to the connecting portion 221 by a connector; the adjusting arm 222 is configured to adjust the position of the temperature sensor 210 relative to the area to be detected.

[0046] In the above implementation process, the temperature sensor 210 is mounted on the probe bracket 220 with its probe facing the area to be detected. This design ensures that the sensor can be directly aligned with the area to be detected, acquiring accurate temperature data. The second fixed end is fixed to the joint 221 of the probe bracket 220 via a connector. This fixing method not only ensures the stability of the temperature sensor 210 but also facilitates installation and disassembly, maintenance, and replacement. The joint 221 provides a stable mounting platform for fixing the second fixed end of the temperature sensor 210. The adjusting arm 222 can be adjusted in multiple directions, including but not limited to up / down, left / right, and rotational adjustments, ensuring that the temperature sensor 210 can be accurately aligned with the area to be detected. The monitoring component is communicatively connected to the detection component 200, receiving the temperature data collected by the temperature sensor 210. The monitoring component can analyze this data in real time, generate a temperature distribution map, promptly detect anomalies, and issue alarms.

[0047] Optionally, the detection assembly 200 further includes a third adjustment knob 231; the third adjustment knob 231 is configured to control the angle of the adjustment arm 222 relative to the area to be detected.

[0048] In the above implementation process, the third adjustment knob 231 provides the detection component 200 with flexibility in angle adjustment, enabling the detection arm to be precisely adjusted in angle according to the specific position and shape of the area to be detected. In actual operation, by rotating the third adjustment knob 231, the adjustment arm 222 can be adjusted at multiple angles relative to the area to be detected, thereby ensuring that the detection component 200 can contact or scan the area to be detected at the optimal angle, improving the accuracy and reliability of the detection.

[0049] Optionally, the third adjustment knob 231 is marked with graduations, allowing the operator to precisely adjust the angle as needed.

[0050] Optionally, setting the damping of the third adjustment knob 231 can ensure that the adjusted angle is stable and will not be easily changed by external force or vibration.

[0051] Optionally, the monitoring component 400 includes: an alarm unit (not shown); the alarm unit is configured to issue an alarm signal and / or shut down when the analysis results are abnormal.

[0052] In the above implementation process, the alarm unit adds active early warning and safety protection functions to the detection device. During the detection process, the monitoring component 400 analyzes the detection data in real time. Once the analysis results are found to exceed the preset normal range, the alarm unit will be activated immediately. Exceeding the preset normal range includes: dimensional deviations exceeding tolerances, surface defects exceeding acceptable standards, etc.

[0053] In one embodiment of this application, the alarm signal can be an audible and visual alarm, such as emitting a piercing alarm sound and flashing warning lights, to attract the attention of on-site operators and ensure that operators can respond to abnormal situations in a timely manner. Simultaneously, the alarm unit can also be configured to trigger a shutdown command upon detecting an abnormality, automatically stopping the operation of the detection device.

[0054] In one embodiment of this application, when inspecting high-speed rotating mechanical parts, if cracks or other serious defects are detected, the alarm unit can immediately issue an alarm and stop the machine to prevent equipment damage or personal injury caused by component breakage. In the inspection of electronic components, if abnormal electrical performance is found, the alarm unit can promptly alert operators to take action, preventing defective products from entering subsequent production stages.

[0055] Secondly, please refer to Figure 2 , Figure 2 The detection system provided in the embodiments of this application.

[0056] This application provides a detection system, which includes multiple detection devices arranged around the workpiece to be detected.

[0057] In the above process, multiple inspection devices inspect the workpiece from different directions, ensuring that every area of ​​the workpiece is covered. This avoids missing some critical areas due to the limited field of view of a single inspection device, thereby improving the comprehensiveness and accuracy of the inspection. Multiple inspection devices work simultaneously, and through parallel inspection, comprehensive inspection of complex or large workpieces can be completed in a short time, improving production efficiency and reducing production cycles.

[0058] Optionally, for workpieces with complex structures or multiple inspection areas, multiple inspection devices can perform specialized inspections on different areas. For example, one inspection device can focus on inspecting the surface quality of the workpiece, another can inspect the internal structure, and yet another can inspect dimensional accuracy. This clearly defined inspection method can improve the targeting and effectiveness of the inspection.

[0059] Optionally, the number of detection devices, the number of detection components on the detection devices, and the angle can be increased or decreased as needed for the area to be detected.

[0060] Optionally, the multiple detection devices include: a first detection device 10, a second detection device 20, and a third detection device 30; the first detection device 10 includes a clamping assembly 100 for clamping the workpiece to be tested; the second detection device 20 includes a first detection assembly 21 and a second detection assembly 22; wherein, the first temperature sensor 210 in the first detection assembly 21 faces the first detection area of ​​the workpiece to be tested, and the second temperature sensor 210 in the second detection assembly 22 faces the second detection area of ​​the workpiece to be tested; the third detection device 30 includes a third detection assembly 31 and a fourth detection assembly 32; wherein, the third temperature sensor 210 in the third detection assembly 31 faces the third detection area of ​​the workpiece to be tested, and the fourth temperature sensor 210 in the fourth detection assembly 32 faces the fourth detection area of ​​the workpiece to be tested; wherein the first detection area, the second detection area, the third detection area, and the fourth detection area are not in the same location on the workpiece to be tested.

[0061] In the above implementation process, by setting temperature sensors 210 at different locations, multiple key areas of the workpiece under test can be monitored simultaneously. The clamping component 100 in the first detection device 10 fixes the workpiece under test, ensuring its stability during the detection process. In the second detection device 20, the first detection component 21 and the second detection component 22 monitor the temperatures of the first and second test areas, respectively. In the third detection device 30, the third detection component 31 and the fourth detection component 32 monitor the temperatures of the third and fourth test areas, respectively. The first temperature sensor 210 specifically monitors the temperature of the first test area, the second temperature sensor 210 specifically monitors the temperature of the second test area, the third temperature sensor 210 specifically monitors the temperature of the third test area, and the fourth temperature sensor 210 specifically monitors the temperature of the fourth test area. The temperature sensor 210 of each detection component 200 can collect temperature data in real time and transmit the data to the monitoring component 400. The monitoring component 400 can analyze this data in real time and promptly detect temperature anomalies. Multiple detection devices operate simultaneously; through parallel detection, comprehensive temperature detection of complex or large workpieces can be completed in a short time, improving production efficiency and reducing production cycles.

[0062] Please see Figure 3 , Figure 3 Examples of detection results provided for embodiments of this application.

[0063] The component to be tested is fixed by the clamping assembly 100 in the first testing device 10. The first testing component 21 and the second testing component 22 in the second testing device 20 monitor the temperatures of the first and second testing areas, respectively. The third testing component 31 and the fourth testing component 32 in the third testing device 30 monitor the temperatures of the third and fourth testing areas, respectively. The first testing component 21, the second testing component 22, the third testing component 31, and the fourth testing component 32 each generate four temperature curves. In the context of solder joint testing, these temperature curves represent the temperature changes of different solder joints (different testing areas) on electronic components or circuit boards during the heating process. Solder joint testing is typically used to evaluate soldering quality, ensuring the reliability of solder joints and the stability of the circuit. A significant temperature increase in CH03 (green curve) may indicate excessive heat input during the soldering process, requiring investigation to determine if overheating or improper soldering parameter settings have occurred. The temperature change trends of channels CH01 (red curve) and CH02 (blue curve) are similar, both showing a tendency to stabilize after initial slight fluctuations, with relatively stable temperature changes. This indicates that the heat input to these two solder joints is relatively uniform during the soldering process, and the soldering quality may be good. CH04 (cyan curve) shows the smallest temperature change, which may indicate that the heat input to this solder joint is less during the soldering process. It is necessary to check whether this leads to insufficient soldering or soldering defects.

[0064] In solder joint detection, the temperature curve can help engineers understand the behavior of solder joints under different temperature conditions, thereby evaluating the quality and reliability of solder joints. For example, by observing the temperature changes of solder joints during the heating process, it is possible to detect whether there are voids, cracks or other defects in the solder joints, and these defects may affect the thermal conductivity and mechanical strength of the solder joints. In addition, by comparing the temperature changes of different solder joints, the consistency of the welding process and the uniformity of the solder joints can be evaluated.

[0065] Optionally, when the temperature in a certain area suddenly rises, drops or changes unusually, the monitoring component 400 can immediately issue an alarm through the indicator light 410 and the display screen 420 to remind the operator to check.

[0066] Optionally, when the detection is qualified, the indicator light 410 emits a green light; when the detection is unqualified, the indicator light 410 emits a yellow light; the collected data is read in the display screen 420 to generate a real-time temperature curve. When a temperature sensor 210 detects that the temperature exceeds the set critical value, an over-temperature alarm will be triggered, the indicator light 410 will turn red and the device will stop running.

[0067] Optionally, in the detection of electronic components, the temperatures in different areas have different effects on the performance and lifespan of the components. Through multi-area monitoring, the thermal performance of the components can be comprehensively evaluated.

[0068] Optionally, in machining, the temperature changes in different machining areas can reflect the distribution of thermal stress during the machining process, helping to optimize the machining process.

[0069] Optionally, a data export port 430 is set to support data export, which is used to back up and uniformly save the temperature rise data after each test for later traceability.

[0070] In an embodiment of the present application, the product is tested under a constant temperature environment and high current conditions; the temperature of each solder joint is collected starting from 1 s / run after power-on. Under long-term operation, there will be a temperature rise curve for each solder joint; then the tested temperature rise curve is compared with the normal temperature rise curve in the database. If the temperature rise is within the database threshold range, it is determined that the welding is qualified; if the temperature rise is outside the threshold range, it is determined that it is unqualified and needs to be re-welded. During the test, a maximum temperature critical value can be set. When a certain solder joint exceeds the critical temperature value, an alarm device can be triggered and the tested product can be stopped to avoid accidents.

[0071] In one embodiment of the present application, the test starts with well-welded joints under the same test conditions. A set or several sets of temperature rise curves of the welds are obtained through the test and entered into the database of the control system as the standard control group. Then, the weld joints to be tested are tested, and the test curves are compared with those of the standard control group. If the temperature rise range is within the given error value, it is judged as qualified; otherwise, it is judged as unqualified.
