[0022] Combined with Figure 1 、 Figure 2 And Figure 3As shown, the airtightness inspection equipment for PHA wire harness terminals includes a cabinet body 1. Inside the cabinet body 1, there is a partition board 2. On the partition board 2, there is a detection device 3. The detection device 3 includes a terminal head jig 4 on the partition board 2 for placing the terminal head of the PHA wire harness terminal 9. On the front of the terminal head jig 4, there is a wire harness support seat 5 for placing the wire harness of the PHA wire harness terminal 9. On the back of the terminal head jig 4, there is a code scanning mechanism 6. On one side of the wire harness support seat 5, there is a manipulator 7. Specifically, the airtightness inspection equipment for PHA wire harness terminals aims to ensure that the airtightness of PHA wire harness terminals meets strict standards during the production process, thereby improving the overall quality and reliability of the products. The cabinet body 1 is made of high-strength and corrosion-resistant metal materials, and its surface is treated with rust prevention and anti-static measures to ensure the stable operation of the equipment in harsh industrial environments. The partition board 2, as an important component inside the cabinet body 1, supports the detection device 3 through its stable structure to ensure the stability and accuracy of the detection process.

The detection device 3 is also equipped with high-precision sensors and a data processing system, which can record and analyze the detection results in real time and automatically judge whether the product is qualified. The terminal head jig 4 is manufactured using precision machining processes to ensure a perfect match with the terminal head of the PHA wire harness terminal 9. The surface of the terminal head jig 4 is covered with soft materials to prevent damage to the terminals during the detection process. At the same time, the terminal head jig 4 is internally designed with air guiding channels to facilitate the injection and leakage detection of gas. The wire harness support seat 5 is located on the front of the terminal head jig 4 and is used to stably support the PHA wire harness. The code scanning mechanism 6 is installed on the back of the terminal head jig 4 and is used to automatically identify the barcode or QR code information on the PHA wire harness terminal 9 to achieve rapid product traceability and data management. The manipulator 7 is set on one side of the wire harness support seat 5 and has the characteristics of high precision and high flexibility. The manipulator 7 can automatically grasp, move, and release the PHA wire harness under program control to achieve the automation of the detection process. This not only improves the detection efficiency but also reduces the errors and safety hazards caused by manual operations. The airtightness inspection equipment for PHA wire harness terminals provides an efficient and accurate solution for the airtightness detection of PHA wire harness terminals through its advanced detection technologies and highly automated design. The application of this equipment will greatly improve the production efficiency and quality level of products and meet the market's demand for high-quality electronic products.

[0023] Combined with Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the terminal head jig 4 includes a jig seat 41, a lower jig 42 is arranged on the jig seat 41, and screw rods 43 are symmetrically arranged on both sides of the lower jig 42. An upper jig 44 matching the lower jig 42 is slidably connected to the screw rod 43, and the upper jig 44 has a driving mechanism 45 for driving it to move up and down along the screw rod 43. Specifically, the terminal head jig 4 ensures the stability and accuracy of the PHA harness terminal during the detection process. The jig seat 41 is made of high-strength and high-stability materials, such as high-quality aluminum alloy or stainless steel, to ensure that the entire jig structure can be firmly supported during the detection process. The lower jig 42 is custom-designed according to the specific shape and size of the PHA harness terminal 9 to ensure a perfect match with the terminal head. In order to ensure the precise positioning of the PHA harness terminal during the detection process, a plurality of positioning pins or positioning grooves are provided on the lower jig 42. These positioning structures can closely match the corresponding parts of the PHA harness terminal to prevent displacement or shaking during the detection process. The screw rod 43 serves as the lifting guide rail of the upper jig 44, so that the upper jig 44 can slide steadily and smoothly on the screw rod 43 to achieve vertical lifting. The upper jig 44 is also custom-designed according to the shape and size of the PHA harness terminal, forming a clamping structure with the lower jig 42. The driving mechanism 45 usually includes components such as a motor, a reducer, and a transmission mechanism, which are used to drive the upper jig 44 to move up and down along the screw rod 43. The driving mechanism 45 of the terminal head jig 4 can be integrated with the overall control system of the equipment to achieve automatic control and data interaction. Through programming settings, the lifting height and speed of the upper jig 44 can be automatically adjusted to meet different detection requirements.

[0024] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, sealing strips 46 are provided at the interfaces of the upper jig 44 and the lower jig 42. A buffer 47 is installed on the lower jig 42, and a negative pressure vacuum machine is connected to the back of the lower jig 42. Specifically, the upper jig 44 and the lower jig 42, as clamping components in the PHA wire harness terminal airtightness inspection equipment, are not only related to the accurate positioning of the terminals but also directly affect the accuracy and reliability of the airtightness detection. The sealing strip 46 is made of materials with high elasticity and aging resistance, such as silicone, rubber, or high molecular elastomers. These materials have good sealing performance and chemical corrosion resistance, ensuring that a tight sealing interface is formed when the upper jig 44 and the lower jig 42 are closed to prevent gas leakage. The design of the sealing strip 46 fully considers the shape and size of the PHA wire harness terminals to ensure perfect fit with the interfaces of the upper jig 44 and the lower jig 42. The cross-sectional shape may be circular, square, or irregular to increase the contact area of the sealing surface and the sealing effect. At the same time, the sealing strip 46 also has a certain amount of compression to compensate for the wear and deformation of the jigs during long-term use. The sealing strip 46 is fixed to the interfaces of the upper jig 44 and the lower jig 42 through special card slots or adhesives, and the installation is simple and fast. During use, regularly checking the wear condition of the sealing strip and promptly replacing the damaged sealing strip are important measures to maintain the detection accuracy and extend the service life of the equipment. The buffer 47 is installed on the lower jig 42 and mainly plays a role in buffering and shock absorption. When the upper jig 44 moves downward under the drive of the drive mechanism 45, the buffer 47 can absorb part of the impact energy, slow down the collision speed between the upper jig 44 and the lower jig 42, and protect the PHA wire harness terminals from damage. At the same time, the buffer 47 can also improve the smoothness and accuracy of the detection process to a certain extent. The back of the lower jig 42 is connected to the negative pressure vacuum machine to form a closed air pressure detection system. During the detection process, the negative pressure vacuum machine pumps air into the terminal head jig 4 through the pipeline to create a negative pressure environment inside the terminal head jig 4. At this time, if the airtightness of the PHA wire harness terminal is good, external gas cannot enter the terminal head jig 4; on the contrary, if there is a leakage point in the terminal, external gas will enter the terminal head jig 4 through the leakage point, resulting in a decrease in negative pressure. By monitoring the change of negative pressure, it can be judged whether the airtightness of the PHA wire harness terminal is qualified.

[0025] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the wire harness support base 5 includes a fixing base 51 for placing the wire harness, and an adjusting mechanism 52 is provided at the bottom of the fixing base 51 for adjusting the relative distance between the wire harness support base 5 and the terminal head jig 4. Specifically, the fixing base 51 is the main part of the wire harness support base 5 and is made of a sturdy and durable material such as high-strength plastic or aluminum alloy. Its surface is specially treated, such as with an anti-slip texture design, to ensure that the wire harness does not affect the accuracy of the test results due to sliding or shaking during the detection process. The shape and size of the fixing base 51 are designed according to the actual specifications of the PHA wire harness to provide the best support effect. The adjusting mechanism 52 is installed at the bottom of the fixing base 51 for adjusting the relative distance between the wire harness support base 5 and the terminal head jig 4, enabling the device to flexibly handle wire harnesses of different lengths and specifications, ensuring that the wire harness can accurately dock with the terminal head jig 4 during the detection process, thereby achieving precise airtightness detection. The adjusting mechanism 52 may adopt various adjustment methods, such as manual adjustment, electric adjustment, or pneumatic adjustment, etc. The manual adjustment method usually realizes the fine adjustment of the distance by rotating a knob, moving a slider, or adjusting a screw, etc.; the electric adjustment method realizes the precise control of the distance through a transmission mechanism such as a motor driving a lead screw or a slide rail; the pneumatic adjustment method uses components such as a pneumatic cylinder to achieve fast and stable adjustment. Which adjustment method to specifically adopt needs to be comprehensively considered according to the actual requirements of the device and the production cost.

[0026] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the code scanning mechanism 6 includes a fixing frame 61 provided on the partition plate 2, and a code scanner 62 is provided at the top of the fixing frame 61, and the scanning head of the code scanner 62 is precisely aligned with the two-dimensional code on the PHA wire harness terminal 9. Specifically, the code scanning mechanism 6, as an automated identification component in the PHA wire harness terminal airtightness inspection device, efficient and accurate code scanning ability is crucial for realizing the rapid traceability and data management of products. The fixing frame 61 is installed on the partition plate 2 and is made of a high-strength and corrosion-resistant material to ensure a stable posture during the operation of the device and not to shift or loosen due to vibration or external force. To meet the code scanning requirements of PHA wire harness terminals 9 of different specifications and positions, the fixing frame 61 is designed with adjustable mounting holes or slide rail structures, which enables the code scanner 62 to be finely adjusted in the horizontal and vertical directions according to the actual situation to ensure the precise alignment of the scanning head. The core component of the code scanner 62 is the scanning head, which adopts advanced image recognition technology and high-precision optical elements and can quickly and accurately identify the two-dimensional code on the PHA wire harness terminal 9. The design of the scanning head fully considers the size, density, and reflective characteristics of the two-dimensional code to ensure a stable scanning effect under various light conditions.

[0027] Combined with Figure 2 , Figure 4, Figure 5 and Figure 6 As shown, the manipulator 7 can grasp and rotate the PHA wire harness terminal 9 on the wire harness support base 5 to simulate the rotation and movement in actual use. Specifically, the manipulator 7, as a key execution component in the PHA wire harness terminal airtightness inspection equipment, aims to simulate the rotation and movement experienced by the PHA wire harness terminal 9 wire harness in actual use. The clamping mechanism of the manipulator 7 adopts a multi-degree-of-freedom design, which can flexibly adapt to PHA wire harness terminals 9 with different sizes, shapes, and materials. The inside of the clamping jaw is equipped with precise transmission mechanisms and sensors to ensure accurate and stable grasping of the wire harness during the clamping process while avoiding damage to the wire harness.

[0028] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick-release structure is provided on the fixture base 41, and fixed pull rings 48 are provided on both the upper fixture 44 and the lower fixture 42. Specifically, the quick-release structure on the fixture base 41 greatly simplifies the disassembly and assembly process of the upper fixture 44 and the lower fixture 42. Traditional disassembly and assembly methods may require tools for tightening or loosening, which is time-consuming and laborious. The quick-release structure, through ingenious mechanical designs such as snap fasteners, locking pins, or quick clamps, makes the disassembly and assembly of the fixture easy and fast, greatly improving work efficiency. The quick-release structure not only pursues the speed of disassembly and assembly but also pays attention to the accuracy of positioning. During the disassembly and assembly process, the quick-release structure can ensure that the relative positions between the upper fixture 44 and the lower fixture 42 and the fixture base 41 remain unchanged, avoiding deviations caused by disassembly and assembly operations, thus ensuring the accuracy of the detection results. The fixed pull rings 48 provided on the upper fixture 44 and the lower fixture 42 provide a convenient means of handling for the operator. When it is necessary to move or adjust the position of the fixture, the operator can apply force by grasping the pull ring to easily and safely complete the handling work. The design of the fixed pull ring 48 fully considers the ergonomic principle, making the handling process more labor-saving and comfortable.

[0029] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a control panel 8 is provided on the cabinet body 1. Specifically, the cabinet body 1 serves as the main structure of the PHA wire harness terminal airtightness inspection equipment, which not only bears various components inside the equipment but also realizes the monitoring and operation of the overall operation state of the equipment through the control panel 8 thereon. The control panel 8 adopts an intuitive and easy-to-understand graphical interface design, enabling operators to quickly get started without professional training. The interface usually includes various function buttons, indicator lights, and display screens, clearly marking the operation instructions and status information of the equipment. To ensure the convenience and safety of operation, the various controls on the control panel 8 are carefully arranged. The commonly used function buttons are placed in easily accessible positions, while the important status indicator lights adopt eye-catching colors and sizes for operators to observe the operation state of the equipment at any time. The control panel 8 is provided with start and stop buttons for controlling the start and shutdown of the equipment. These buttons are usually equipped with anti-misoperation designs to ensure that they will not be accidentally shut down during the operation of the equipment. As an important part of the PHA wire harness terminal airtightness inspection equipment, the control panel 8 not only provides a convenient operation interface and rich functional features but also continuously meets the needs and development trends of users through intelligent upgrading and expandability design.
