[0002] A car radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. Coolant flows inside the radiator core, while air passes outside. To prevent coolant leaks, the radiator core needs to be leak-tested.

[0003] Currently, common testing equipment uses a light source generator to emit light, a charge-coupled device to detect light leakage points, and then manual marking is required before rework. This method of light-based leak testing does not damage the heat sink core. However, the heat sink core consists of multiple flat tubes, and there may be tiny light leakage points that are difficult to detect in the gaps between these tubes, affecting the testing results.

[0004] Therefore, there is an urgent need for a device that facilitates the inspection of radiator core welding to solve this problem. Utility Model Content

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0022] like Figures 1 to 2 As shown, a device for facilitating the welding and inspection of radiator cores includes: a housing 100, a mounting bracket 200, a first moving mechanism, a second moving mechanism, a light source mechanism, a detection mechanism, a lifting mechanism, a sensor 700, and a control system. The housing 100 has an internal cavity, and the mounting bracket 200 is disposed within the cavity. The first moving mechanism is mounted on the mounting bracket 200 and drives the second moving mechanism, which in turn drives the detection mechanism. The light source mechanism and the sensor 700 are both mounted on the detection mechanism. The lifting mechanism is movably mounted on the mounting bracket 200, and the control system is also mounted on the mounting bracket 200. The first moving mechanism, the second moving mechanism, the light source mechanism, the detection mechanism, the lifting mechanism, and the sensor 700 are all electrically connected to the control system.

[0023] Specifically, there are two of each of the first moving mechanism, the second moving mechanism, the light source mechanism, and the detection mechanism. Two placement plates 210 are provided on the mounting frame 200, and each first moving mechanism is located on one side of one placement plate 210. Each first moving mechanism includes a first drive motor 310, a first lead screw 320, and two first slide rails 330. The first drive motor 310, the first lead screw 320, and the two first slide rails 330 are all located on one side of the placement plate 210. The two first slide rails 330 are located on both sides of the first lead screw 320. The output shaft of the first drive motor 310 is connected to the first lead screw 320. A first slider 340 is slidably disposed on the first lead screw 320. The first slider 340 is slidably connected to the two first slide rails 330 respectively. A second moving mechanism is disposed on one of the first sliders 340. Each of the second moving mechanisms includes a second drive motor 410, a connecting frame 420, a second lead screw 430, and a light-blocking plate 440. The connecting frame 420 is disposed on the first slider 340, the second drive motor 410 is disposed on the connecting frame 420, and the output shaft of the second drive motor 410 is connected to the second lead screw 430. The light-blocking plate 440 is slidably disposed on the second lead screw 430. Each of the light source mechanisms includes a first light source 510 and a second light source 520, both of which are disposed on the light-blocking plate 440. Both detection mechanisms are vision cameras. The lifting mechanism includes a tooling plate 610, a lifter 620, and a placement seat 630. The tooling plate 610 is used for external connection, the lifter 620 is disposed on one side of the tooling plate 610, and the lifter 620 is used to drive the placement seat 630. The placement seat 630 is used to place the heat sink core. The sensor 700 is used to detect the position of the placement seat 630. An electrical box 800 is mounted on the mounting bracket 200, and the control system is located inside the electrical box 800. The control system is a PLC control system.

[0024] In other words, this device for testing the welding of radiator cores needs to be used in conjunction with an external conveying device. That is, the lifting mechanism can be mounted on the external conveying device, which will pass through the middle of the housing 100, and will carry the lifting mechanism through the middle of the two light-blocking plates 440.

[0025] In operation, the operator places the radiator core to be tested on a placement seat 630. Then, as it is conveyed by the conveyor belt, the radiator core enters the housing 100. When the radiator core moves to the middle of the two light-blocking plates 440, a sensor 700 detects whether the entire radiator core is positioned between the two light-blocking plates 440, which is equivalent to being within the detection area. In other words, the control system determines whether the position of the radiator core needs adjustment based on the signal detected by the sensor 700, for example, by adjusting it forward and backward via the conveyor belt, or by adjusting it up and down via the lifting device 620.

[0026] In other words, after the position of the radiator core is adjusted, the inspection begins. The light-blocking plates 440 on both sides are adjusted by the first and second drive motors 310, respectively, to bring the first light source 510, the second light source 520, and the vision camera close to the area of ​​the radiator core requiring light leakage detection. Then, the first light source 510 is turned on, illuminating the area from above. The vision camera then takes pictures to confirm whether light leakage occurs and sends the images to the control system. Next, the first light source 510 is turned off, and the second light source 520 is turned on, illuminating the area from the front. The vision camera again takes pictures to confirm whether black spots appear and sends the images to the control system, thus completing the entire light leakage detection process. The control system then identifies and judges the captured images to draw specific conclusions. In other words, the staff can directly see the condition of each radiator core being inspected on the control system and can intuitively see whether light leakage occurs. The entire process is simple, convenient, and provides good detection results.

[0027] In summary, the above embodiments are not limiting embodiments of this utility model. Any modifications or equivalent variations made by those skilled in the art based on the substantive content of this utility model are within the technical scope of this utility model.
