Description

Technical Field

[0001] This utility model relates to the field of radiator testing technology, and in particular to a device for detecting defects in radiator cores. Background Technology

[0002] The radiator core of an automotive radiator consists of radiator fins, radiator tubes, main fins, and side plates. Before brazing, the radiator core needs to be assembled with a frame to secure it. The frame is removed after brazing. After the radiator core is assembled with the frame, the overall structure of the radiator core and frame needs to be visually inspected to check for defects such as tube breakage or short fins. Brazing can only proceed after these defects are ruled out. Currently, this defect inspection is done manually. Workers must lift the entire structure consisting of the radiator core and frame and then visually inspect it. A complete radiator core and frame structure weighs approximately 15 kg, and manual inspection significantly increases the workload of workers and reduces inspection efficiency.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components.

[0034] The radiator core of an automotive radiator consists of radiator fins, radiator tubes, main fins, and side plates. Before brazing, the radiator core needs to be assembled with a frame to secure it. The frame is removed after brazing. After the radiator core is assembled with the frame, the overall structure of the radiator core and frame needs to be visually inspected to check for defects such as tube breakage or short fins. Brazing can only proceed after the inspection is completed without defects. Currently, this defect inspection is done manually. Workers need to lift the entire radiator core and frame structure and then visually inspect it. A complete radiator core and frame structure weighs approximately 15 kg, and manual inspection significantly increases the workload of workers and reduces inspection efficiency.

[0035] Therefore, this embodiment provides a heat sink defect detection device 100 to solve the above problems. The heat sink defect detection device 100 can help reduce manual input and improve detection efficiency.

[0036] like Figures 1-4 As shown, the heat sink defect detection device 100 of this embodiment includes a clamping unit and an imaging unit. The clamping unit is used to place and clamp the heat sink 200 and the frame 300 as a whole, preventing the heat sink 200 and the frame 300 from shaking or shifting during the imaging process, thus helping to ensure clear images. The imaging unit is connected to the clamping unit and includes a first imaging component and a second imaging component. The first imaging component is used to photograph the heat dissipation strip 201 of the heat sink 200, and the second imaging component is used to photograph the heat dissipation pipe 202 of the heat sink 200.

[0037] Staff can check the results of the first and second photo-taking components to determine whether there are any appearance defects in the heat dissipation strips 201 and heat dissipation pipes 202 of the heat dissipation core 200. It is no longer necessary to manually lift the entire structure of the heat dissipation core 200 and frame 300 and change the angle. Therefore, the heat dissipation core defect detection device 100 helps to reduce manual input and improve detection efficiency.

[0038] Optionally, the clamping unit includes a placement frame, which is horizontally positioned. The overall structure of the heat sink 200 and the frame 300 is horizontally placed on the placement frame, and for ease of shooting, the heat sink 200 is positioned above the frame 300.

[0039] Optionally, multiple sets of first imaging components are arranged at intervals along a first direction, and all sets of first imaging components are located above the heat sink 200, with the first direction being horizontal. Figure 1 In the diagram, direction ab is the first direction, and direction cd is the second direction. The second direction is horizontal and perpendicular to the first direction. Setting multiple sets of first imaging components ensures that even when the heat sink 200 has a large dimension along the first direction, clear images can be obtained from all areas. Optionally, each set of first imaging components is equipped with a support frame 12, which supports the first imaging component.

[0040] Optionally, the first imaging component includes a first camera 1, the lens of which is directed toward the heat sink 200 for imaging. Optionally, since the first camera 1 is located above the heat sink 200, the lens of the first camera 1 is directed vertically downwards. Of course, in other embodiments, the lens of the first camera 1 can be adjusted to be tilted downwards.

[0041] Optionally, the first photographing component includes a first fill light 2, which emits light toward the heat sink 200 to ensure sufficient light at the heat dissipation strip 201 visible on the end face of the heat sink 200, so that the first camera 1 can capture a clear image.

[0042] Optionally, the second imaging component is provided in two sets, with the two sets of second imaging components located on both sides of the heat sink 200 along the first direction, respectively corresponding to the heat sink pipes 202 on both sides of the heat sink 200 along the first direction.

[0043] Optionally, the second imaging component includes a second camera 3, the lens of which is directed toward the heat sink 200 for imaging. Optionally, since the second camera 3 is located on the side of the heat sink 200, the lens of the second camera 3 is oriented horizontally. Of course, in other embodiments, the lens of the second camera 3 can be adjusted to a tilted position so that the heat sink 202 of the heat sink 200 is located at the center of the image captured by the second camera 3.

[0044] Optionally, the second photographing component includes a second fill light 4, which emits light toward the heat sink 200 to ensure sufficient light at the heat sink 202 visible on the side of the heat sink 200, so that the second camera 3 can capture a clear image.

[0045] When the size of the heat sink 200 is large, in order to ensure that clear images are obtained from all areas, optionally, multiple sets of first imaging components can be moved along a first direction and a second direction. That is, if the first imaging component can be moved along the first direction, images of multiple areas sequentially arranged along the first direction on the end face of the heat sink 200 can be obtained; if the first imaging component can be moved along the second direction, images of multiple areas sequentially arranged along the second direction on the end face of the heat sink 200 can be obtained.

[0046] Optionally, both sets of second imaging components can be moved along the first direction and the second direction. That is, if the second imaging component can be moved along the first direction, images of multiple areas sequentially arranged along the first direction can be obtained; if the second imaging component can be moved along the second direction, images of multiple areas sequentially arranged along the second direction can be obtained.

[0047] To enable the first imaging component to move along the first direction, the imaging unit may optionally include multiple shifting drive components 5, each shifting drive component 5 driving a group of the first imaging components to move along the first direction. The shifting drive components 5 are mounted on the support frame 12. Optionally, in this embodiment, two sets of the first imaging components and the shifting drive components 5 are provided, with the two sets of shifting drive components 5 arranged opposite each other along the first direction, and each set of shifting drive components 5 driving two sets of the first imaging components to move along the first direction. The output end of the shifting drive component 5 is connected to the first support component, and the first camera 1 and the first fill light 2 are both mounted on the first support component. Optionally, the shifting drive component 5 is a cylinder or a linear motor.

[0048] To enable the second imaging component to move along the first direction, the imaging unit may optionally further include two sets of first sliding components, such as... Figure 2 As shown, each set of first sliding components includes a first slide rail 6 and a first slide table 7. The first slide table 7 and the first slide rail 6 are slidably engaged. Both first slide rails 6 extend along a first direction. The two sets of second imaging components are respectively set on the two first slide tables 7. The first slide table 7 can drive the second imaging components to move along the first slide rail 6.

[0049] Optionally, both sets of first sliding components are equipped with a first sliding drive, and the first slide table 7 is connected to the output end of the first sliding drive. The first sliding drive is used to drive the first slide table 7 to move along the first slide rail 6. Optionally, the first sliding drive is a linear motor.

[0050] To enable the movement of the first and second imaging components along the second direction, the imaging unit may optionally include two sets of second sliding components. In this embodiment, one set of first imaging components and one set of second imaging components move synchronously, and another set of first imaging components and another set of second imaging components move synchronously. The two sets of second sliding components are respectively located on both sides of the heat sink 200 along the first direction.

[0051] Each set of second sliding components includes a second slide rail 8 and a second slide table 9. The second slide table 9 is slidably engaged with the second slide rail 8. Both second slide rails 8 extend along a second direction. A shifting drive 5 and a first slide rail 6 are each connected to one second slide table 9. The shifting drive 5 is connected to the second slide table 9 via a support frame 12. When the second slide table 9 moves along the second slide rail 8, it drives the shifting drive 5, the first imaging component, the first sliding component, and the second imaging component to move synchronously along the second direction. Another shifting drive 5 and another first slide rail 6 are each connected to another second slide table 9. When this second slide table 9 moves along the second slide rail 8, it drives the shifting drive 5, the first imaging component, the first sliding component, and the second imaging component on the other side to move synchronously along the second direction. Optionally, both second slide rails 8 are connected to a placement frame.

[0052] Optionally, both sets of second sliding components are equipped with a second sliding drive, and the second slide table 9 is connected to the output end of the second sliding drive. The second sliding drive is used to drive the second slide table 9 to move along the second slide rail 8. Optionally, the second sliding drive is a linear motor.

[0053] Optionally, the clamping unit includes at least two clamping assemblies, both of which are mounted on the mounting bracket. The at least two clamping assemblies are located at at least two corners of the overall structure, one-to-one. Figure 2 As shown, in this embodiment, there are two sets of clamping components, which are located at opposite corners of the overall structure.

[0054] like Figure 3 As shown, optionally, each clamping assembly includes a clamping member 10, which can be moved downwards to clamp the top of the frame 300. The clamping assembly secures the overall structure by fixing the frame 300, thus preventing damage to the heat sink 200.

[0055] Optionally, the clamping member 10 has a connected horizontal surface and a vertical surface, with the horizontal surface facing vertically downward and the vertical surface facing the frame 300 and located outside the area enclosed by the frame 300. When the clamping member 10 moves downward, the horizontal surface can press against the top of the frame 300, and the vertical surface can contact the outer side of the frame 300, that is, the vertical surface can restrict the horizontal position of the overall structure.

[0056] Optionally, in this embodiment, since the placement rack can move as a whole along the first direction, the two vertical surfaces of the two clamping members 10 are respectively located on the two outer surfaces of the frame 300 along the first direction, so as to jointly restrict the position of the frame 300 relative to the placement rack along the first direction.

[0057] Optionally, each clamping assembly includes a lifting drive 11, and the clamping member 10 is connected to the output end of the lifting drive 11 via a second support member, so that the lifting drive 11 can drive the clamping member 10 to move up and down. Optionally, the lifting drive 11 is a cylinder or a linear motor.

[0058] The operating steps of the heat sink defect detection device 100 are as follows:

[0059] In the assembly area, a robotic arm places the heat sink 200 and frame 300 together onto the placement platform of the heat sink defect detection device 100. Then, the clamping member 10 clamps the frame 300. The imaging unit then takes a picture of the heat sink 200. The image can be manually reviewed to determine if the heat sink 200 has any appearance defects, or the image can be analyzed using inspection software. Next, a robotic arm in the unloading area is manually controlled to remove the heat sink 200 and frame 300 together and place it in the acceptable or unacceptable area. Alternatively, the robotic arm can be electrically controlled to complete the appearance defect detection and classification of the heat sink 200.
