Description

Technical Field

[0001] This utility model relates to the field of helium testing technology for automotive parts, specifically to an automated helium testing device for automotive electrical components and controls. Background Technology

[0002] With the rapid development of the automotive industry, especially the popularization of new energy vehicles and intelligent connected vehicles, the importance of automotive electronic components (such as engine control units (ECUs), transmission control units (TCUs), battery management systems (BMSs), and on-board chargers (OBCs)) in the vehicle is becoming increasingly prominent. These electronic control units (ECUs) are typically encapsulated in precision housings, integrating highly sensitive electronic components. To ensure their long-term reliability and stability under complex vehicle operating environments (such as high temperature, high humidity, vibration, and water exposure), their housings must possess extremely high sealing performance to prevent the intrusion of moisture, dust, and other corrosive gases.

[0003] Currently, leak detection of automotive electronic control units (ECUs) is a crucial quality control step in the production process. In recent years, helium mass spectrometry (HMS) leak detection has become the "gold standard" for high-precision leak detection due to its extremely high sensitivity and accuracy. This method uses helium as a tracer gas and a helium mass spectrometer to detect leaks, enabling the quantitative detection of even extremely small leaks. However, applying helium mass spectrometry leak detection technology to large-scale production lines for automotive ECUs still faces many challenges. However, existing helium testing equipment usually only performs helium testing on a certain type of electronic control, which has a limited scope of application and cannot meet the diversified testing needs of electronic control in new energy vehicles. Therefore, we propose an automated helium testing equipment for automotive electronic control. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1, as Figures 1-5 As shown, this embodiment proposes an automated helium detection device for automotive electrical components, including a frame 1. A base 6 is fixedly connected inside the frame 1. An electric slide rail 3 is fixedly connected inside the frame 1 via a bracket. An electric sliding block 4 is slidably connected to the outer surface of the electric slide rail 3. A detection module 5 is fixedly connected to the outer surface of the electric sliding block 4.

Control buttons 9 are fixedly connected to the outer surface of the controller 2. A control keyboard 10 is fixedly connected to the lower end of the controller 2 near the front end. A drag chain 8 is connected inside the frame 1 to the sliding part corresponding to the electric sliding block 4. The detection module 5 is used to perform helium detection on the electrical components. The detection module 5 is moved up and down by the electric sliding block 4 to perform helium detection. The controller 2 is used to display relevant helium detection data. The control buttons 9 are used to control the operation of the helium detection. The control keyboard 10 is used to input relevant parameters for the helium detection.

[0019] The base 6 includes a connecting groove 71 opened at the upper end of the base 6, a movable block 72 connected to the upper end of the base 6, a protrusion 73 fixedly connected to the upper end of the movable block 72, a connecting module 74 connected to the lower end of the movable block 72, and a connecting head 75 fixedly connected to the upper end of the protrusion 73.

[0020] The connecting module 74 includes a connecting block 741 fixedly connected to the lower end of the movable block 72; the connecting module 74 includes a groove 742 formed on the lower surface of the movable block 72, the connecting block 741 is slidably connected to the inner side of the lower end of the movable block 72 corresponding to the groove 742, a recessed groove 743 is formed on the top surface of the connecting block 741, a fixing post 744 is fixedly connected to the inner side of the lower end of the movable block 72, and a pushing spring 745 is sleeved on the outer surface of the fixing post 744; the connecting groove 71 is a groove-shaped structure of a regular square prism, the lower end of the connecting block 741 matches the connecting groove 71, the connecting head 75 together with the protrusion 73 is used to position the detection electronic control module, the movable block 72 is used to support the electronic control module to be tested, and helium detection is performed by contacting the electronic control module through the lower end of the detection module 5.

[0021] The connecting block 741 slides up and down along the slide groove 742. The recessed groove 743 matches the lower end of the fixed post 744. The inner diameter of the actuating spring 745 is larger than the diameter of the fixed post 744. The outer diameter of the actuating spring 745 is smaller than the diameter of the slide groove 742. The actuating spring 745 provides buffering during the installation of the movable block 72. The connecting block 741 and the movable block 72 are slidably connected.

[0022] In this embodiment, the movable block 72 used for positioning the electronic control module can be replaced, so that the protrusions 73 and connectors 75 with different structures can position different electronic control modules.

[0023] In summary, the practical principle of this utility model is as follows: When testing is required, the user can vertically place the lower end of the electronic control module to be tested, corresponding to the position of the connector 75 and the protrusion 73, downwards. At this time, the electronic control module is positioned and maintains positional stability. Then, the electric sliding block 4 drives the detection module 5 to slide downwards, so that the lower end of the detection module 5 contacts the electronic control module, thereby performing helium testing. After the test is completed, the electric sliding block 4 drives the detection module 5 upwards, and then the electronic control module is vertically removed upwards, thus completing the test of the set of electronic control modules. It should be noted that the installation and movement of the aforementioned electrical control module can also be automatically controlled by a robotic arm, and the entire process can be automated for production and testing through a PLC control module.

[0024] When other electronic control modules need to be tested, the user can vertically grasp the movable block 72 and remove the movable block 72, connecting module 74, movable block 72, and connecting head 75. Then, the connecting block 741 at the lower end of the new movable block 72 is vertically inserted downwards, corresponding to the opening of the connecting groove 71. During this process, the push spring 745 will retract a certain distance, and the connecting block 741 will also retract a certain distance into the groove 742 until the movable block 72 is in contact with the upper end of the base 6. At this point, the installation of the movable block 72 is completed. Based on the replaceable feature of the movable block 72, different positions or sizes of protrusions 73 and connecting heads 75 can be replaced to meet the needs of helium testing of different electronic control modules, resulting in better performance.
