[0002] Microchannel aluminum flat tubes are a new type of high-efficiency heat exchange material, widely used in air conditioning, automotive radiators, and electronic device heat dissipation. Microchannel aluminum flat tubes contain multiple tiny channels that increase the contact area between the fluid and the tube wall, thereby improving heat exchange efficiency.

Existing technologies typically employ defect marking devices to pinpoint the defect locations. These devices include inkjet nozzles that spray ink onto the aluminum flat tube surface to facilitate subsequent inspection and repair.

[0042] Microchannel aluminum flat tubes are a new type of high-efficiency heat exchange material, widely used in air conditioning, automotive radiators, and electronic device heat dissipation. Microchannel aluminum flat tubes contain multiple tiny channels that increase the contact area between the fluid and the tube wall, thereby improving heat exchange efficiency.

[0043] During the production of microchannel aluminum flat tubes, defects such as scratches, dents, oxide spots, or uneven surfaces are prone to occur. Existing technologies typically employ defect marking devices to pinpoint the defect locations. These devices include inkjet nozzles that use inkjet printing to mark the surface of the aluminum flat tube, facilitating subsequent inspection and repair.

[0046] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0047] Please refer to Figure 1 This embodiment provides a defect detection device, including a support assembly 100, which includes a support platform 110; a defect detection assembly, which is used to detect defects on the surface of the workpiece 500 when it passes the support platform 110; and a marking assembly 200, which is mounted above the support platform 110 and includes a defect marking element 210 and a driving element 220. The driving element 220 is connected to the defect marking element 210 and is used to drive the defect marking element 210 to swing relative to the support platform 110 so that defects on the workpiece 500 are marked by the defect marking element 210 when it passes the defect marking element 210.

[0048] Specifically, in this embodiment, the support component 100 is used to support and position the test piece 500 and the marking component 200. The support component 100 includes a support platform 110, the surface of which is flat, to provide stable support for the test piece 500 and the marking component 200, ensuring that the test piece 500 and the marking component 200 can be placed stably on the support platform 110.

[0049] In this embodiment, the shape and size of the support platform 110 can be adaptively adjusted according to the shape and size of the test piece 500 and the marking component 200. This embodiment does not impose any restrictions on this.

[0050] In this embodiment, the component to be tested 500 is a microchannel aluminum flat tube. To enable continuous testing of the microchannel aluminum flat tube, an unwinding device is connected to the support assembly 100. The unwinding device is used to gradually unwind the rolled microchannel aluminum flat tube and transport it to the support platform 110 of the support assembly 100.

[0051] The unwinding equipment includes an unwinding shaft and a tension control device. The unwinding shaft is used to fix the roll of microchannel aluminum flat tube, and the tension control device is used to adjust the tension of the microchannel aluminum flat tube during the unwinding process to ensure that the microchannel aluminum flat tube does not become loose or overstretched during transportation.

[0052] In other embodiments, the workpiece to be inspected 500 may also be other workpieces that require defect identification and marking, and this embodiment does not impose any restrictions on this.

[0053] Specifically, the defect detection device provided in this embodiment includes a defect detection component and a marking component 200. The defect detection component is used to detect defects on the surface of the workpiece 500 when it passes through the support platform 110, so as to determine whether there are defects on the surface of the workpiece 500.

[0054] The marking assembly 200 is mounted above the support platform 110. The marking assembly 200 includes a defect marking element 210 and a driving element 220. The driving element 220 is connected to the defect marking element 210 and is used to drive the defect marking element 210 to swing relative to the support platform 110 so that when the part to be inspected 500 passes by the defect marking element 210, the defect on the part to be inspected 500 is marked by the defect marking element 210.

[0055] Specifically, in this embodiment, when the defect detection component detects a defect on the surface of the current workpiece 500 to be inspected, it sends a command to the drive component 220 to start the drive component 220 and drive the defect marker 210 to swing relative to the support platform 110. This allows the defect on the workpiece 500 to be quickly marked by the defect marker 210 as it passes by, ensuring the accuracy of the defect marking. This facilitates subsequent operators in quickly locating the defect and carrying out further inspection or repair work.

[0056] Specifically, in some embodiments, when the drive member 220 drives the defect marker 210 to swing relative to the support platform 110, the swing speed and action mode can be flexibly controlled according to the length of the defect on the test piece 500.

[0057] For example, when the defect detected by the defect detection component is relatively long, the drive unit 220 can control the defect marker 210 to swing to a position where it contacts the workpiece 500 under inspection and remain there. As the unwinding equipment continues to transport the workpiece 500 under inspection, the defect marker 210 will draw a long line on the surface of the workpiece 500 under inspection until it reaches the end position of the defect. Then, the drive unit 220 controls the defect marker 210 to swing back to its initial position and disengage from the workpiece 500 under inspection. This allows the defect marker 210 to form a clear and continuous mark on a long defect, making it easier for subsequent operators to identify and further improving the accuracy of defect marking.

[0058] Conversely, when the defect detected by the defect detection component is short, the drive unit 220 can control the defect marker 210 to quickly perform a reciprocating swing without stopping. This causes the defect marker 210 to form a dot or a short straight line on the surface of the workpiece 500. Because the unwinding device continuously transports the workpiece 500, marking of short defects can be completed quickly in a short time, while avoiding excessively long marks or unnecessary marking traces caused by stopping, and preventing contamination of the surface of the workpiece 500.

[0059] In this embodiment, the defect marker 210 is a marking pen. The marking pen directly contacts the part to be inspected 500 to mark defects, avoiding clogging that may occur during inkjet printing, thus ensuring the stability and continuity of the marking process. Simultaneously, the marking process of the marking pen does not produce liquid diffusion or contamination, and after marking, no excess residue is left on the surface of the part to be inspected 500, ensuring the cleanliness of the surface of the part to be inspected 500 and the clarity of the defect marking.

[0060] When the marking pen wears out or runs out, operators can quickly replace it with a new one without complicated maintenance procedures, thus improving the operating efficiency and maintenance convenience of the defect detection equipment.

[0061] Please refer to Figure 1 In some embodiments, the defect detection component includes an image-taking module and a detection module. The image-taking module is used to take an image of the part to be inspected 500 as it passes the support platform 110. The detection module is used to determine whether there is a defect on the part to be inspected 500 based on the image data taken by the image-taking module.

[0062] Specifically, in this embodiment, the defect detection component includes an image-taking module and a detection module. The image-taking module is located above the support platform 110 and is used to take a picture of the part to be inspected 500 as it passes by, acquiring surface image data of the part to be inspected 500. The detection module is connected to the image-taking module and is used to receive the captured data and analyze and determine whether there are defects on the surface of the part to be inspected 500.

[0063] Specifically, in this embodiment, the imaging module includes a line scan camera and an area scan camera. The line scan camera uses a line array sensor, capable of scanning the surface of the workpiece 500 line by line, enabling rapid and high-precision image acquisition of the continuously moving workpiece 500. The area scan camera uses a two-dimensional sensor, capable of capturing a large area of ​​the surface of the workpiece 500 at once, allowing for comprehensive inspection of the workpiece 500. Through the coordinated operation of the line scan camera and the area scan camera, defects on the surface of the workpiece 500 can be accurately detected, ensuring the accuracy of defect identification.

[0064] In other embodiments, only line scan cameras or only area scan cameras may be set. At the same time, this embodiment does not impose any restrictions on the specific arrangement and number of line scan cameras and area scan cameras, and can make an adaptive selection according to actual needs.

[0065] In this embodiment, the detection module processes the image data acquired by the imaging module. The detection module compares the images captured by the imaging module with pre-stored defect-free standard images. These defect-free standard images are obtained during the production process by capturing images of the surface of the workpiece 500 that is normal and without defects, and are used as a benchmark for inspection. By comparing the differences between the acquired images and the standard images, the detection module identifies whether defects exist on the surface of the workpiece 500, and the specific location and type of the defects. For example, if a certain area in the image captured by the imaging module has a significant difference in brightness, color, or shape compared to the defect-free standard image, it can be determined that the area may contain defects such as scratches, dents, or oxide spots, ensuring the accuracy of defect identification.

[0066] Furthermore, it should be noted that in this embodiment, the detection module can calculate the time when the defect of the part to be inspected 500 reaches the defect marker 210 based on the shooting speed of the camera module and the transportation speed of the part to be inspected 500. At the same time, it can also calculate the response speed of the drive unit 220 and the running time of the defect marker 210, so that when the part to be inspected 500 reaches the defect marker 210, the defect marker 210 can accurately mark the defect position of the part to be inspected 500.

[0067] Please refer to Figure 1 In some embodiments, the defect detection device further includes a control component. The drive component 220 has a rotatable drive section connected to the defect marker 210, and the drive section, when rotating, can cause the defect marker 210 to swing relative to the support platform 110. The control component is connected to the drive component 220 and is used to control the rotation of the drive section when the defect detection assembly detects a defect.

[0068] Specifically, in this embodiment, the defect detection device further includes a control component. The drive component 220 has a rotatable drive section connected to the defect marker 210, so that when the drive component 220 is activated, the defect marker 210 can be rotated via the drive section.

[0069] Specifically, the control unit is electrically connected to the drive unit 220, and the control unit can receive signals from the defect detection component. When the defect detection component detects a defect on the surface of the workpiece 500 to be inspected, the control unit activates the drive unit 220 to rotate the drive unit, thereby moving the defect marker 210 above the defect to mark the defect on the workpiece 500 to be inspected.

[0070] In this embodiment, the driving component 220 can be a motor, and the driving part is the output shaft of the motor. When the control component receives a signal from the defect detection component, the output shaft of the motor rotates forward, causing the defect marker 210 to swing to a position in contact with the part to be inspected 500, thus marking the defect. After marking is completed, the output shaft of the motor reverses, causing the defect marker 210 to swing to a position away from the part to be inspected 500, completing one marking action. This ensures that the defect marker 210 is in contact with the part to be inspected 500 during marking and quickly detaches after marking, avoiding contamination of the part to be inspected 500 and facilitating identification by subsequent operators.

[0071] Please refer to Figure 1 In some embodiments, the defect detection device further includes a host computer, which is communicatively connected to both the defect detection component and the control component. The host computer transmits instructions to the control component when the defect detection component detects a defect, and the control component controls the drive unit to rotate upon receiving the instructions.

[0072] Specifically, the defect detection equipment also includes a host computer. The host computer is communicatively connected to both the defect detection component and the control component. When the defect detection component detects a defect on the surface of the workpiece 500, the host computer receives a signal from the defect detection component, generates a corresponding control command based on the signal, and transmits the control command to the control component. Upon receiving the command from the host computer, the control component immediately controls the drive unit to rotate, thereby causing the defect marker 210 to perform corresponding actions to mark the defect location.

[0073] In this embodiment, the host computer is a computer. The computer has a data processing module inside, which can receive and process signals from the defect detection component.

[0074] Specifically, the data processing module can analyze the signals transmitted from the defect detection component to determine the location of the defect. Simultaneously, the data processing module can generate corresponding control commands and send these commands to the control component via the communication interface, thereby achieving precise control of the drive component 220 and ensuring that the defect marker 210 can accurately mark the defect location.

[0075] Please refer to Figure 1 In some embodiments, the defect marker 210 has a fixed end 211 and a marking end 212. The fixed end 211 is connected to and fixed relative to the drive unit. The fixed end 211 is used to drive the marking end 212 to swing relative to the support platform 110 when the drive unit rotates, so as to mark the defects on the test piece 500.

[0076] Specifically, in this embodiment, the defect marker 210 has a fixed end 211 and a marking end 212. The fixed end 211 is connected to and fixed relative to the drive unit, so that when the drive unit rotates, the fixed end 211 drives the marking end 212 to swing relative to the support platform 110 to mark the defects on the test piece 500.

[0077] In this embodiment, the marking end 212 is the tip of the defect marking element 210, used to mark the part to be inspected 500.

[0078] In some embodiments, the fixed end 211 of the defect marker 210 is connected to the drive unit via a detachable connection, such as a threaded connection, a snap-fit ​​connection, or a plug-in connection. This allows operators to quickly remove the defect marker 210 from the drive unit when it needs to be replaced or maintained, thereby improving the maintenance efficiency of the defect detection equipment and reducing maintenance costs.

[0079] Please refer to Figure 1 In some embodiments, the marking assembly 200 further includes a retaining sleeve 230 and a locking member. A retaining end 211 passes through the retaining sleeve 230 along its axial direction, and a driving part is connected to the retaining sleeve 230. The retaining sleeve 230 has two connecting portions 231 bent away from the driving part in the circumferential direction, and a gap exists between the two connecting portions 231 along the circumferential direction of the retaining sleeve 230. The two connecting portions 231 are used to ensure that the retaining end 211 is located within the retaining sleeve 230 and is fixed to the retaining sleeve 230 when they are connected and close to each other. The locking member passes through the two connecting portions 231 to connect them.

[0080] Specifically, in this embodiment, the fixing sleeve 230 is a hollow structure, and a receiving cavity is formed inside the fixing sleeve 230 to accommodate the fixing end 211. The receiving cavity is matched and configured to accommodate the fixing end 211. The fixing end 211 is inserted into and passes through the fixing sleeve 230 along the axial direction, thereby positioning the fixing end 211 through the receiving cavity and ensuring the stability of the fixing end 211.

[0081] In this embodiment, the driving unit is connected to the fixed sleeve 230 to drive the fixed sleeve 230 and the defect marker 210 to swing so as to mark the workpiece 500 to be inspected.

[0082] For example, in this embodiment, the drive unit is provided with an external thread. The drive unit is inserted into the fixed sleeve 230 along the circumferential direction of the fixed sleeve 230, and the insertion end of the drive unit extends out of the fixed sleeve 230. The operator can achieve a fixed connection between the fixed sleeve 230 and the drive unit by screwing the nut at the insertion end.

[0083] In other embodiments, the connection method between the drive unit and the fixed sleeve 230 can be adapted according to actual needs. This embodiment does not impose any restrictions on this.

[0084] Specifically, in this embodiment, the fixing sleeve 230 has two connecting portions 231 bent toward the side opposite to the driving part in the circumferential direction. A gap exists between the two connecting portions 231 along the circumferential direction of the fixing sleeve 230. When the two connecting portions 231 approach and connect to each other, the connecting portions 231 can firmly clamp the fixing end 211 within the fixing sleeve 230, thereby achieving mutual fixation between the fixing end 211 and the fixing sleeve 230.

[0085] A locking element is used to connect the two connecting parts 231. During installation, the locking element can be inserted into the two connecting parts 231, causing them to approach and fit tightly together. Specifically, the locking element can be a bolt. The threaded portion of the bolt matches the threaded hole on the connecting part 231. When the bolt is tightened, it forces the two connecting parts 231 closer together, thereby firmly clamping the fixed end 211 within the fixing sleeve 230. This ensures the stability of the fixed end 211 within the fixing sleeve 230 while facilitating quick disassembly and replacement of the defect marking element 210.

[0086] In other embodiments, locking elements may be selected adaptively according to actual needs, and this embodiment does not impose any restrictions on this.

[0087] Please refer to Figure 1 In some embodiments, the drive element 220 includes a pneumatic electromagnetic element, and the drive part is a rotating shaft in the pneumatic electromagnetic element.

[0088] Specifically, in this embodiment, the pneumatic electromagnetic component is a pneumatic solenoid valve, which includes a solenoid valve and a pneumatic system. The driving part is the rotating shaft of the pneumatic system. The airflow direction and pressure of the pneumatic system are controlled by the solenoid valve, which can drive the rotating shaft to rotate and control the rotation direction of the rotating shaft.

[0089] Specifically, when the defect detection component detects a defect on the surface of the workpiece 500, the control component sends an electrical signal to the solenoid valve. Upon receiving the signal, the solenoid valve controls the airflow direction, driving the drive unit to rotate. The rotation of the drive unit causes the fixed end 211 of the defect marker 210 to rotate, causing the defect marker 210 to swing relative to the support platform 110, thereby marking the workpiece 500.

[0090] Specifically, because the pneumatic solenoid valve has a fast response speed, it can complete the entire process from signal reception and airflow switching to shaft rotation in a short time. Therefore, it can ensure that the defect marker 210 can still accurately mark the defect location during the rapid movement of the workpiece 500 under test, thus ensuring the accuracy and reliability of the marking.

[0091] Please refer to Figure 1 In some embodiments, the defect detection device further includes a mounting component 300, which is disposed on the support component 100, and a marking component 200 is movably disposed on the mounting component 300 along the height direction of the support component 100.

[0092] Specifically, in this embodiment, the mounting component 300 is disposed on the support component 100 for supporting and positioning the marking component 200. The marking component 200 is movably disposed on the mounting component 300 along the height direction of the support component 100, thereby accommodating test pieces 500 of different heights.

[0093] Specifically, in this embodiment, the mounting assembly 300 includes a guide rail disposed along the height direction of the support assembly 100, and the marking assembly 200 is connected to the guide rail via a slider. The slider can slide along the guide rail, thereby driving the marking assembly 200 to move along the height direction of the support assembly 100 to accommodate test pieces 500 of different heights.

[0094] In some embodiments, the height adjustment of the marking component 200 is achieved manually. Specifically, the mounting component 300 has multiple height adjustment holes, which are evenly and spaced apart. The operator can manually control the marking component 200 to slide along the guide rail. When the marking component 200 reaches the desired height position, a pin is inserted through the marking component 200 into the corresponding height adjustment hole on the mounting component 300, thereby fixing the marking component 200 in that position and ensuring that the marking component 200 does not shift during operation.

[0095] In other embodiments, the mounting assembly 300 includes a push rod motor. The push rod motor is capable of precisely controlling the marking assembly 200 to slide along the guide rail to the desired height. When the desired height position is reached, the push rod motor is capable of holding the marking assembly 200 in that position, thereby achieving stepless height adjustment of the marking assembly 200 and facilitating precise control of the height of the marking assembly 200.

[0096] Please refer to Figure 1 In some embodiments, the mounting assembly 300 includes a mounting base 310 and a rotating member 320. The mounting base 310 is disposed on the support assembly 100, and the rotating member 320 is disposed on the mounting base 310. The marking assembly 200 also includes a movable member, and a driving member 220 is disposed on the side of the movable member facing the support platform 110. The movable member is threadedly connected to the rotating member 320, and the rotating member 320 is used to drive the movable member to move along the height direction of the support assembly 100 when rotating.

[0097] Specifically, in this embodiment, the mounting assembly 300 includes a mounting base 310 and a rotating member 320. The mounting base 310 is fixedly mounted on the support assembly 100 and is used to support and position the marking assembly 200. The rotating member 320 is mounted on the mounting base 310 and is capable of rotating about its own axis.

[0098] The marking assembly 200 also includes a movable component, and a driving component 220 is disposed on the side of the movable component facing the support platform 110, for driving the movement of the defect marking component 210. The movable component and the rotating component 320 are connected by threads. When the rotating component 320 rotates, due to the action of the threads, the movable component will move along the thread direction, that is, move up and down along the height direction of the support assembly 100, thereby realizing the height adjustment and positioning of the marking assembly 200 to accommodate the inspection component 500 at different heights.

[0099] Please refer to Figure 1 In some embodiments, the defect detection device further includes a limiting member 400, which is rotatably disposed above the support platform 110 and has a space between itself and the support platform 110 for the test piece 500 to pass through. The limiting member 400 is used to contact the test piece 500 when it passes through the space.

[0100] Specifically, in this embodiment, the defect detection equipment also includes a limiting member 400. The limiting member 400 is rotatably disposed above the support platform 110 and has a space between it and the support platform 110 for the test piece 500 to pass through. When the test piece 500 passes through the space between the limiting member 400 and the support platform 110 during transmission, the limiting member 400 can contact the test piece 500, thereby positioning and guiding the test piece 500, preventing the test piece 500 from shifting or shaking during transmission, and ensuring the accuracy and reliability of the detection and marking process.

[0101] In some embodiments, the defect detection device further includes a detection element 500, which is mounted above the support platform 110 and is used to detect information about the component to be inspected 500, including whether the component to be inspected 500 has a mark.

[0102] Specifically, in this embodiment, the detection element 500 is a color sensor, which is mounted above the support platform 110, along the transmission direction of the element to be detected 500, and located after the marking assembly 200. The color sensor determines the presence of a mark by detecting color changes on the surface of the element to be detected 500. When the element to be detected 500 passes by the color sensor, the color sensor can identify the color difference between marked and unmarked areas, thereby determining whether there is a mark on the element to be detected 500.

[0103] Specifically, if the defect marker 210 performs a marking action or the control unit issues a command, but the color sensor does not detect the mark, it means that the marking action was not successfully completed. The color sensor can send relevant information to the host computer. The host computer will process the received information and issue an alarm signal so that operators can promptly repair the defect detection equipment.

[0104] In other embodiments, the detection element 500 may also be of other structures, and an adaptive selection can be made according to actual needs. This embodiment does not impose any restrictions on this.

[0105] Finally, it should be noted that other embodiments of this utility model will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of this utility model that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
