Description

Technical Field

[0001] This application relates to the field of product testing, and in particular to an automated testing device for radiators. Background Technology

[0002] In the field of machinery manufacturing, radiators, as a crucial heat dissipation component, have an extremely wide range of applications, covering many key areas such as electronic equipment and automotive engines. With the rapid development of technology, various industries are constantly raising their requirements for equipment performance and stability, which has driven the continuous expansion of radiator production. High-quality radiators play an indispensable role in the entire industrial system, effectively ensuring the stable operation of equipment, significantly extending its service life, and greatly reducing failures and losses caused by heat dissipation problems, providing a solid foundation for efficient and stable industrial production. One type of radiator mainly consists of a welded plate and several heat dissipation fins. The ends of the heat dissipation fins extend with welded sections to form a U-shaped structure. Each heat dissipation fin is arranged on the upper and lower surfaces of the welded plate and firmly welded to the surface of the welded plate through its welded sections. Therefore, during the production process of the radiator, it is necessary to ensure that the orientation of the U-shaped heat dissipation fins is correct during welding. Currently, the inspection of this type of radiator mainly relies on manual inspection, carried out sequentially step by step. The inspectors first use simple tools to check the welded points to see if they are secure and if there are any points prone to breakage. After completing this step, they carefully check the installation direction of the welded heat sinks to determine if they are installed backwards. This manual inspection method can ensure the quality of heat sinks to a certain extent in small-scale factory production.

[0003] However, existing methods for inspecting such radiators have significant drawbacks. Because the inspection process relies entirely on manual operation, its efficiency is insufficient to meet the demands of large-scale production. Furthermore, the precision of human visual inspection is limited, making it impossible to accurately assess the quality of the radiators. In addition, manual inspection is easily affected by factors such as the inspector's experience and fatigue, leading to frequent missed and false positives. This poses a significant challenge to ensuring the overall quality of radiators and fails to meet the requirements of modern large-scale, high-quality industrial production. Summary of the Invention

[0004] To meet the needs of automated testing of radiators, improve testing efficiency and accuracy, and effectively avoid missed or false detections, this application provides an automated radiator testing device.

[0005] This application provides an automated radiator testing device, including a frame, a loading and clamping mechanism, a solder joint detection mechanism, a transfer mechanism, a front and back detection mechanism, an unloading and clamping mechanism, and an image acquisition mechanism mounted on the frame. The loading and clamping mechanism transports the radiator to be tested to the solder joint detection mechanism for solder joint firmness testing. The image acquisition mechanism acquires solder joint image information during the detection process of the solder joint detection mechanism and provides feedback on the recognition results. The transfer mechanism transfers the radiator with normal solder joints to the front and back detection mechanism for identification and detection of the front and back of the heat sink, and provides feedback on the identification results. The unloading and clamping mechanism transports the radiator with normal front and back detection to the finished product area. By adopting the above technical solution, the loading and clamping mechanism can automatically transport the radiator to be tested to the solder joint detection mechanism, changing the previous manual step-by-step inspection method, avoiding the problem of low efficiency of manual operation, and improving the initial efficiency of the inspection process. The image acquisition mechanism can acquire solder joint image information and provide feedback on the recognition results during the solder joint inspection process. Compared to the limited accuracy of human visual inspection, the image acquisition mechanism can accurately identify the solder joint condition, reducing misjudgments caused by insufficient accuracy of manual inspection and improving the accuracy of solder joint inspection. The transfer mechanism automatically transfers the heat sink with normal solder joints to the front and back inspection mechanism for identification and inspection of the front and back of the heat sink and provides feedback on the results. This makes the inspection process smooth and orderly, avoiding errors and delays that may occur during manual transfer, and further improving inspection efficiency. The unloading and clamping mechanism transports the heat sink with normal front and back inspection to the finished product area, realizing the automatic classification and transportation of the heat sink after inspection. This ensures the automation and efficiency of the entire inspection process, adapts to the requirements of large-scale, high-quality production in modern industry, improves the overall efficiency and quality of heat sink inspection, and reduces the occurrence of missed and false inspections. Preferably, the solder joint inspection mechanism includes a first base and two impact plate assemblies. The first base has a first positioning groove in the middle for placing the heat sink to be inspected. The two impact plate assemblies are located on both sides of the first positioning groove and are used to apply impact force to both sides of the heat sink to be inspected for impact testing. By adopting the above technical solution, in the solder joint inspection mechanism, a first positioning groove is provided in the middle of the first base for placing the heat sink to be inspected, providing a stable placement position for the heat sink. Two impact plate assemblies located on either side of the first positioning groove can apply impact force to both sides of the heat sink to be inspected. Since the solder joints of the heat sink are prone to breakage when subjected to impact force if they are not strong, this impact test method can effectively detect the strength of the solder joints, thereby improving the accuracy of the solder joint quality inspection. Preferably, the impact plate assembly includes an impact plate and an impact driving component. The impact driving component is disposed on the top of the first base, and an elastic buffer plate is provided on the side of the impact plate near the heat sink to be inspected. The impact driving component drives the impact plate to move until the elastic buffer plate contacts the heat sink to be inspected.By adopting the above technical solution, the impact driving component is disposed on the top of the first base, which can stably drive the impact plate to move. When the impact driving component drives the impact plate to move towards the heat sink under test, since the side of the impact plate close to the heat sink under test is provided with an elastic buffer plate, the elastic buffer plate can play a buffering role at the moment of contact with the heat sink under test, avoiding damage to the heat sink under test due to excessive impact force. At the same time, it can also make the impact force more evenly applied to the heat sink under test, thereby more accurately detecting the firmness of the weld. Preferably, both ends of the first positioning groove extend to the edge of the first base to form two openings, and a positioning plate is provided at one end opening of the first positioning groove. Gaps are formed between the two sides of the positioning plate and the first positioning groove. By adopting the above technical solution, the two ends of the first positioning groove extend to the edge of the first base to form two openings, which facilitates the placement and removal of the heat sink under test. The positioning plate provided at one end opening of the first positioning groove can play a positioning role for the heat sink under test, so that the heat sink is accurately placed in the first positioning groove. A gap is formed between the two sides of the positioning plate and the first positioning groove, providing space for the push rods of the subsequent transfer mechanism to pass through. This allows the push rods to pass through the gaps and enter the first positioning groove to contact the heat sink under test, thereby realizing the transfer operation of the heat sink and improving the automation level and detection efficiency of the device. Preferably, the transfer mechanism includes two push rods and a push rod driver. The push rods correspond one-to-one with the gaps, and the push rod driver drives the two push rods to pass through the gaps respectively into the first positioning groove and contact the heat sink under test. By adopting the above technical solution, the push rods of the transfer mechanism correspond one-to-one with the gaps formed between the two sides of the positioning plate and the first positioning groove at one end of the opening of the first positioning groove. The push rod driver drives the two push rods to pass through the gaps respectively into the first positioning groove and contact the heat sink under test. The existence of the gaps provides a channel for the movement of the push rods, allowing them to smoothly enter the first positioning groove and thus push the heat sink under test to move within the first positioning groove, realizing the transfer operation of the heat sink under test and improving the automation level and continuity of the detection process. Preferably, the front and back detection mechanism includes a second base and a sliding detection block. The second base has a second positioning groove in its center for placing the heatsink to be tested. The second positioning groove and the first positioning groove are axially connected and share the same central axis. The sliding detection block is suspended above the second positioning groove and can move along the arrangement direction of the heatsink fins to identify the front and back of each heatsink fin. By adopting the above technical solution, since the second positioning groove and the first positioning groove are axially connected and share the same central axis, the heatsink that has undergone solder joint testing can smoothly enter the second positioning groove.Furthermore, because the sliding detection block is suspended above the second positioning groove and can move along the arrangement direction of the heat sink fins of the heat sink to be tested, when the heat sink is placed in the second positioning groove, the sliding detection block can fully contact each heat sink fin during its movement, thereby identifying the front and back of each heat sink fin. This achieves automated detection of the front and back of the heat sink fins, improving detection efficiency and accuracy. Preferably, the second base is provided with a moving push block and a limiting block. The moving push block pushes the heat sink to be tested against the limiting block. By adopting the above technical solution, the moving push block on the second base can apply a pushing force to the heat sink to be tested placed in the second positioning groove. Due to the existence of the limiting block, under the push of the moving push block, the heat sink to be tested will continuously move closer to the limiting block until it abuts against it. This ensures that the heat sink to be tested is in an accurate and stable position in the second positioning groove, providing a good foundation for the subsequent identification and detection of the front and back of the heat sink fins by the sliding detection block, improving the accuracy and reliability of the detection. Preferably, the sliding detection block is provided with a detection protrusion that matches the U-shaped groove of the heat sink to be tested. By adopting the above technical solution, since the sliding detection block is provided with a detection protrusion that matches the U-shaped groove of the heat sink to be tested, when the sliding detection block moves along the arrangement direction of several heat sink fins of the heat sink to be tested, the detection protrusion can be accurately embedded in the U-shaped groove. If the heat sink is installed in the correct direction, the matching between the detection protrusion and the U-shaped groove will be relatively smooth; if the heat sink is installed backwards, the matching between the detection protrusion and the U-shaped groove will be abnormal, and the sliding detection block will not be able to slide smoothly. Thus, accurate identification of the front and back sides of each heat sink can be achieved. Preferably, a pressure sensor is provided on the surface of the detection protrusion. When the pressure sensor detects a pressure signal, the sliding detection block resets. By adopting the above technical solution, by providing a pressure sensor on the surface of the detection protrusion, when the sliding detection block moves along the arrangement direction of several heat sink fins of the heat sink to be tested, if the detection protrusion contacts the heat sink, the pressure sensor will detect a pressure signal. Since the detection protrusion matches the U-shaped groove of the heatsink under test, the detection protrusion should move smoothly within the U-shaped groove under normal circumstances. If the detection protrusion is obstructed and generates a pressure signal, it means that there may be an abnormality such as incorrect installation of the heatsink on the front or back. At this time, the sliding detection block is reset to facilitate subsequent re-inspection or other operations, thus improving the accuracy and efficiency of the inspection. Preferably, it also includes a removal mechanism. The bottom of the first positioning groove and the second positioning groove are movable lifting plates. When an abnormal solder joint or an abnormal front or back is detected in the heatsink under test, the lifting plate moves the heatsink under test downward, and the removal mechanism removes the heatsink under test from the lifting plate.By adopting the above technical solution, when the device detects that the solder joints of the heat sink to be tested are abnormal or that the front and back sides are abnormal, since the bottom of the first positioning groove and the second positioning groove are both movable lifting plates, the lifting plates will drive the heat sink to be tested to move downwards, providing operating space and a suitable position for the removal mechanism, thereby enabling the removal mechanism to smoothly remove the heat sink to be tested from the lifting plate, avoiding defective products from entering the normal process, and ensuring the accuracy and efficiency of the testing process.

[0006] In summary, this application includes at least one of the following beneficial technical effects:

[0007] 1. The feeding clamping mechanism transports the radiator to be inspected to the solder joint inspection mechanism, the transfer mechanism transfers the radiator with normal solder joint inspection to the front and back inspection mechanism, and the unloading clamping mechanism transports the radiator with normal front and back inspection to the finished product area. The various mechanisms cooperate with each other to realize the automated inspection of radiators, avoid the tedious manual inspection of each process, thereby improving the inspection efficiency and meeting the needs of large-scale production.

[0008] 2. The image acquisition mechanism acquires solder joint image information and feeds back the recognition results during the solder joint inspection process. The image recognition technology is used to analyze the solder joint condition. The detection protrusion of the sliding detection block is equipped with a pressure sensor to detect whether the protrusion contacts the heat sink to be inspected during the sliding process of the sliding detection block, thereby identifying the front and back sides. Compared with manual visual observation, the firmness of the solder joint can be accurately judged, solving the problem of limited accuracy of manual inspection.

[0009] 3. A removal mechanism is provided. By designing the bottom of the first and second positioning slots as movable and liftable lifting plates, the lifting plates will drive the heat sink to be tested to move downwards. The removal mechanism will remove the heat sink to be tested from the lifting plates. This application adopts an automated testing method, which eliminates the need for manual operation by testing personnel, further improving testing efficiency. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0016] This application provides an automated radiator testing device, which, according to an embodiment, is... Figure 1 The system includes a frame 1, a loading clamping mechanism 2, a solder joint detection mechanism 3, a transfer mechanism 4, a forward and reverse detection mechanism 5, a unloading clamping mechanism 6, an image acquisition mechanism, a removal mechanism 7, and a control mechanism. In this embodiment, the transfer mechanism 4, solder joint detection mechanism 3, and forward and reverse detection mechanism 5 are sequentially arranged along the Y-axis on the frame 1. The image acquisition mechanism is positioned directly above the solder joint detection mechanism 3 to acquire solder joint image information. The loading clamping mechanism 2 is located beside the solder joint detection mechanism 3, and the unloading clamping mechanism 6 is located beside the forward and reverse detection mechanism 5. Both the solder joint detection mechanism 3 and the forward and reverse detection mechanism 5 have a removal mechanism 7 at their bottom. The control mechanism controls the sequential operation of each mechanism, enabling comprehensive inspection of the heat sink according to a preset process, achieving automated heat sink inspection, and improving inspection efficiency and accuracy. Figure 1 The image acquisition mechanism is not displayed.

[0017] Specifically, in this embodiment, both the loading and unloading clamping mechanisms are conventional suction-type robotic arm structures. These structures consist of a robotic arm body and an end effector. The robotic arm body employs a conventional multi-joint robotic arm structure, driven by a servo motor to achieve precise spatial positioning and complete loading, handling, and unloading actions. The end effector is an integrated vacuum suction cup assembly, a key component that directly contacts the welding plate of the heat sink to be inspected. An air pump or vacuum generator extracts air from the suction cup, creating a localized vacuum environment and generating a pressure difference between the inside and outside of the suction cup, thus achieving non-destructive gripping of the heat sink. Since suction-type robotic arm structures are existing technology, their specific structure and working principle will not be described in detail.

[0018] Reference Figure 2Specifically, the weld joint inspection mechanism 3 includes a first base 31 and two impact plate assemblies 32. The first base 31 is made of cast iron, which has good stability and rigidity, providing stable support for the entire inspection process. A first positioning groove 311 is provided in the middle of the first base 31 for placing the heatsink to be inspected. The shape of the first positioning groove 311 is adapted to the heatsink, accurately fixing its position and preventing displacement during inspection. The two impact plate assemblies 32 are located on both sides of the first positioning groove 311, used to apply impact force to both sides of the heatsink to be inspected for impact testing.

[0019] Specifically, both ends of the first positioning groove 311 extend to the edge of the first base 31 to form two openings. A positioning plate 312 is provided at one end of the opening of the first positioning groove 311, and gaps 313 are formed between the positioning plate 312 and the first positioning groove 311 on both sides. The positioning plate 312 is used to further determine the position of the heat sink, and the gaps 313 provide space for subsequent transfer operations.

[0020] The impact plate assembly 32 includes an impact plate 321 and an impact drive component 322. The impact drive component 322 is disposed on the top of the first base 31, and an elastic buffer plate 323 is disposed on the side of the impact plate 321 near the heat sink under test. The impact drive component 322 is a cylinder that drives the piston rod to move, thereby providing a large driving force to make the impact plate 321 move quickly. The elastic buffer plate 323 is usually made of rubber material. Rubber has good elasticity and can play a buffering role during impact, avoiding excessive damage to the heat sink.

[0021] The working principle of the weld joint inspection mechanism 3 is as follows: the feeding clamping mechanism 2 places the heat sink in the first positioning groove 311, and the positioning plate 312 further positions the heat sink. The impact driving component 322 drives the impact plate 321 to move towards the heat sink, so that the elastic buffer plate 323 contacts the heat sink and applies an impact force. The strength of the weld joint is detected by observing the condition of the heat sink weld joint under the impact force.

[0022] Specifically, the transfer mechanism 4 includes two push rods 41 and a push rod drive 42. The push rods 41 correspond one-to-one with the gaps 313 on both sides of the positioning plate 312 at one end of the first positioning groove 311. The push rod drive 42 drives the two push rods 41 to pass through the gaps 313 into the first positioning groove 311 and contact the heat sink under test. The push rod drive 42 is an electric push rod, which pushes the push rods 41 to extend and retract, enabling rapid extension and retraction of the push rods 41. When the image acquisition mechanism reports a normal solder joint detection result, the push rod drive 42 drives the push rods 41 through the gaps 313 into the first positioning groove 311, pushing the heat sink towards the forward and reverse detection mechanism 5, transferring the heat sink from the first positioning groove 311 to the forward and reverse detection mechanism 5.

[0023] Reference Figure 3 Specifically, the forward and reverse detection mechanism 5 includes a second base 51 and a sliding detection block 52. The second base 51 is also made of cast iron to ensure structural stability. A second positioning groove 511 for placing the heat sink to be tested is provided in the middle of the second base 51. In particular, in this embodiment, the side of the second positioning groove 511 near the first positioning groove 311 has an opening. The second positioning groove 511 and the first positioning groove 311 are axially connected and share the same central axis, which facilitates the transfer of the heat sink from the first positioning groove 311 to the second positioning groove 511.

[0024] The second base 51 is equipped with a movable push block 512 and a limiting block 513. The movable push block 512 and the limiting block 513 are located on opposite sides of the second positioning groove 511. The movable push block 512 can be driven by a cylinder; the extension and retraction of the cylinder causes the movable push block 512 to move, quickly pushing the heatsink. The limiting block 513 restricts the position of the heatsink, ensuring the accuracy of the test. The movable push block 512 pushes the heatsink under test against the limiting block 513, ensuring the accurate positioning of the heatsink during the test.

[0025] The sliding detection block 52 is slidably mounted on one side of the second positioning groove 511 via a linear drive structure 53. The sliding detection block 52 is suspended above the second positioning groove 511 and can move along the arrangement direction of the heat sink fins to identify the front and back of each heat sink fin. Specifically, the sliding detection block 52 has a detection protrusion 521 that matches the U-shaped groove of the heat sink. A pressure sensor 522 is mounted on the surface of the detection protrusion 521. When the pressure sensor 522 detects a pressure signal, the sliding detection block 52 resets. The shape of the detection protrusion 521 matches the U-shaped groove, accurately detecting the front and back of the heat sink fins. The pressure sensor 522 can monitor the contact between the detection protrusion 521 and the heat sink fins in real time. When abnormal pressure is detected, it indicates a potential problem with the front and back of the heat sink fins. At this time, the control mechanism controls the linear drive structure 53 to drive the sliding detection block 52 to reset for further processing. The linear drive structure 53 consists of a linear slide rail and an electric push rod. The linear slide rail is set on the second base 51 along the arrangement direction of several heat sinks of the heat sink to be tested. The electric push rod pushes the sliding detection block 52 to move along the linear slide rail.

[0026] Since the U-shaped groove structure of the three parts of the heat sink in this embodiment faces outward, there are three detection protrusions 521 in this embodiment, which correspond to the U-shaped groove structure of the three parts of the heat sink respectively.

[0027] When the transfer mechanism 4 transfers the heat sink into the second positioning groove 511, the moving push block 512 pushes the heat sink against the limiting block 513, fixing the heat sink in position. The sliding detection block 52 moves along the arrangement direction of the heat sink fins, and the detection protrusion 521 contacts the U-shaped groove of the heat sink fin. The pressure sensor 522 monitors the contact pressure in real time. If the pressure is normal, it indicates that the heat sink fins are installed correctly; if the pressure is abnormal, it indicates that the heat sink fins may be installed backwards, and the sliding detection block 52 will reset.

[0028] Specifically, in this embodiment, the bottom of the first positioning groove 311 and the second positioning groove 511 are both movable lifting plates 8. Specifically, the bottom of the first positioning groove 311 and the second positioning groove 511 are provided with openings. The lifting plates 8 are driven to move up and down by a cylinder. The cylinder can drive the lifting plates 8 to move upward until the lifting plates 8 just block the openings at the bottom of the first positioning groove 311 and the second positioning groove 511, so as to support the heat sink to be tested during the testing process.

[0029] Specifically, in this embodiment, the removal mechanism 7 includes a removal plate 71 and a cylinder. When an abnormal solder joint or an abnormal front and back side of the radiator to be tested is detected, the lifting plate 8 moves the radiator to be tested downward, and the cylinder drives the removal plate 71 to move horizontally until it contacts the radiator, thereby removing the radiator from the testing area.

[0030] Reference Figure 4 Specifically, the image acquisition mechanism includes a support frame and an industrial camera and recognition system mounted on the support frame. The industrial camera features high resolution and high frame rate, enabling it to clearly capture image information of the weld points during the inspection process of the weld point inspection mechanism 3. It can be installed in a suitable position on the support frame to ensure accurate capture of weld point details. During the impact test of the weld point inspection mechanism 3, the industrial camera acquires image information of the weld points in real time and feeds this image information back to the recognition system. The recognition system analyzes the images to determine whether the weld points are normal. The control mechanism operates according to the judgment result of the recognition system.

[0031] The implementation principle of this embodiment is as follows: This automated radiator testing device achieves automated radiator testing through the coordinated operation of various mechanisms. The loading and clamping mechanism 2 transports the radiator to be tested to the solder joint testing mechanism 3. The solder joint testing mechanism 3 tests the solder joint firmness through an impact test, and the image acquisition mechanism acquires solder joint image information in real time. If the solder joint is normal, the transfer mechanism 4 transfers the radiator to the front and back testing mechanism 5 for identification and testing of the front and back of the heat sink. Finally, the unloading and clamping mechanism 6 transports qualified radiators to the finished product area, while unqualified radiators are removed by the removal mechanism 7. This automated testing method greatly improves testing efficiency and accuracy, reduces missed and false detections, and meets the requirements of large-scale, high-quality production in modern industry.

[0032] 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.
