Description

Technical Field

[0001] The invention relates to the technical field of cooler leakage detection, in particular to a production leakage detection device for automobile oil coolers. Background Art

[0002] In terms of leak detection, the core technology of traditional equipment relies on a single pressure detection method. It can only determine whether there is a leak by the change of the internal pressure curve of the cooler, but cannot spatially locate the leak point based on the principles of fluid mechanics or the trajectory of molecular motion. For components such as automotive oil coolers with complex internal pipelines and dense welding interfaces, tiny leaks are often hidden in the bends of the pipelines or in the brazing gaps, and the detection results are non-standard. In addition, during the pressure detection process, the traditional clamping mechanism uses a rigid metal clamp to directly contact the surface of the cooler, and the clamping force is concentrated in a local area. According to statistics, this will cause scratches or dents on the surface of the cooler, especially for coolers with precision surface treatments such as nickel plating and anodizing, causing irreversible damage and increasing the scrap rate. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that traditional equipment relies on a single pressure detection method for leak detection, which can only determine whether there is a leak but cannot locate the location.

[0021] Working principle: Figures 1-9 As shown, cooler loading and conveying: the automobile oil cooler to be tested is placed on the conveyor belt 803 of the conveyor assembly 8, and the second rotary motor 801 drives the roller 802 to rotate, driving the conveyor belt 803 to run, and conveying the cooler to the conveyor belt 505 of the conveyor assembly 5; during this process, the speed of the conveyor belt 803 and the conveyor belt 505 are preset and coordinated by the control panel 11 to ensure smooth transfer of the cooler; Cooler positioning: The cooler moves with the conveyor belt 505 to the top of the inspection station, and the positioning component 9 starts working; the slide plate 901 slides along the slide rail on the support base 1, driving the positioning frame 902 to move to both sides of the cooler. The tension spring in the elastic telescopic rod 903 pushes the clamping plate 904 to clamp the cooler. The elastic cotton 905 prevents the clamping from damaging the cooler surface, achieving precise positioning. At the same time, the conveyor belt 505 is driven by the rotating motor 502 through the rotating rod 503 and the rotating shaft 504, and can be paused or fine-tuned according to positioning requirements; Sealing and pressure application: After positioning is completed, the hydraulic cylinder 303 of the lifting assembly 3 drives the pressure plate 4 to descend, pressing the top of the cooler; at the same time, the clamping assemblies 6 at both ends of the bottom of the lifting assembly 3 are activated, and the inflator 603 inflates the air chambers in the right clamping plate 601 and the left clamping plate 602, so that the sealing gaskets on the inner side of the clamping plates are tightly attached to the two sides of the cooler; Leak detection: After sealing is complete, detection assembly 2 is activated. The pressure sensor array in the array sensor 203 monitors the pressure changes inside the cooler in real time. By filling the cooler with test gas and observing the pressure drop, it is determined whether there is a major leak. The helium mass spectrometer sensor array is used to detect micro leaks. If there is a small gap in the cooler, the helium gas injected will escape and be captured and detected by the helium mass spectrometer sensor array. The sensor array on the inner side of the outer cover plate 202 is closely arranged to ensure all-round monitoring of the cooler's outer surface. Appearance monitoring: During the inspection process, the camera of the monitoring component 7 captures images of the cooler during inspection and transmits them to the image recognition module. The module analyzes the images using a preset algorithm to identify whether there are any appearance defects such as scratches and dents on the cooler surface, and transmits the results to the control panel 11. Result processing and unloading: After the test is completed, the control panel 11 determines whether the cooler is qualified based on the data from the pressure sensor array, the helium mass spectrometer sensor array and the image recognition module. Qualified products are lifted by the lifting component 3, the pressure plate 4 is lifted, the clamping component 6 deflates and releases the clamping plate, and the conveyor belt 505 transports them to the unloading area. Unqualified products trigger an alarm and are removed by manual or automatic sorting devices. Throughout the entire process, each component is precisely linked and time-controlled by the PLC controller in the control panel 11 to ensure efficient and accurate leak detection.
