[0034] like Figure 1-4As shown, an integrated notebook microphone hole sealing inspection fixture includes: a lower template 1, a placement slot 2, an air suction component 3, a booster cylinder 31, a sliding connection 32, a slide 33, an air nozzle 34, an upper template 5, a connecting plate 6, and a buffer block 7. The lower template 1 is fixed to the desktop, the placement slot 2 is opened on the lower template 1, and the air suction component 3 includes a booster cylinder 31, a sliding connection 32, a slide 33 and an air nozzle 34. The booster cylinder 31 is located on one side of the placement slot 2, and the sliding connection 32 is installed at the output end of the booster cylinder 31. The slide 33 is embedded in the sliding connection 32 to ensure that the air nozzle 34 moves smoothly along a straight line to improve the detection accuracy. The air nozzle 34 is installed on one side of the sliding connection 32. As a key part, the air nozzle 34 directly contacts the microphone hole and is used to extract air to form a negative pressure. The position of the upper template 5 corresponds to the lower template 1. The upper template 5 is located above the lower template 1. The connecting plate 6 is installed on the upper template 5 to form a frame structure to support the entire upper component and ensure overall stability.
[0035] Preferably, the buffer block 7 is distributed on the top of the connecting plate 6. There are four buffer blocks 7, which are evenly distributed on the top of the connecting plate 6. The buffer block 7 can provide a buffer for the lowered upper template 5 when the upper template 5 is installed on the lifting mechanism to prevent shaking. The top of the isolation plate 8 is connected to the connecting plate 6, and the bottom of the isolation plate 8 is connected to the isolation plate 8. The isolation plate 8 and the connecting plate 6 form an upper space. The divided space is formed in cooperation with the connecting plate 6 to form an independent upper space, which is conducive to the layout and operation of the upper nozzle 11 assembly.
[0036] In this embodiment, the displacement cylinder 9 is installed in the upper space formed by the isolation plate 8 and the connecting plate 6, the upper nozzle 11 connector 10 is installed at the bottom of the upper template 5, the upper nozzle 11 is set at the bottom of the upper nozzle 11 connector 10, the pull-distance member 12 is located in the extension direction of the upper nozzle 11 connector 10, and the vacuum generator 2613 is connected to the air nozzle 34 through a hose through the sliding connector 32, which is a key device for generating negative pressure. It is connected to the air nozzle 34 through a hose to form a negative pressure environment. The solenoid valve 2714 is installed on the tube body of the hose, the upper template 5 is provided with a weight reduction groove, and the upper nozzle 11 connector 10 is provided with an interface. Control the gas flow, realize the switching between negative pressure generation and pressure maintenance, and facilitate monitoring data collection.
[0037] In this embodiment, the displacement cylinder is installed on the bottom surface of the X-axis displacement plate 13, the card rail 14 is opened on the bottom surface of the X-axis displacement plate 13, and the buffer block is embedded in the card rail 14, the Y-axis telescopic plate 15 is installed on the top of the card rail 14, the Y-axis sleeve plate 16 is sleeved on one end of the Y-axis telescopic plate 15, the Y-axis fixed plate 17 is sleeved on the Y-axis sleeve plate 16, the extension motor 18 is installed above the Y-axis fixed plate 17, the extension screw 19 is installed on the output end of the extension motor 18, the extension connector 20 is sleeved on the extension screw 19, and the extension connector 20 is on the Y-axis telescopic plate 15. When the X-axis displacement is required, the output end of the displacement cylinder only needs to be popped out to push the upper template 5 to perform the X-axis displacement. During the displacement process, the buffer block will slide in the card rail 14 to prevent displacement. When performing Y-axis displacement, the extension motor 18 is started, and the output end of the extension motor 18 drives the extension screw 19. The extension connector 20 slides on the extension screw 19, and the extension connector 20 then drives the Y-axis extension plate 15 and the Y-axis socket plate 16 to perform Y-axis extension and retraction, thereby completing the Y-axis movement.
[0038] Preferably, the Y-axis fixing plate 17 is sleeved on the rod body of the Z-axis screw 21, the top of the lifting plate 22 is connected to the Y-axis fixing plate 17, and slots are provided at both ends of the lifting plate 22. The lifting frame body 23 is erected on one side of the lower template, and two groups of slide rails 24 are provided. The two groups of slide rails 24 are longitudinally distributed on the lifting frame body 23. The lifting motor 25 is installed on the top of the lifting frame body 23. The top of the Z-axis screw 21 is connected to the output end of the lifting motor 25. When the output end of the lifting motor 25 rotates, it will drive the Z-axis screw 21. The rotation of the Z-axis screw 21 will cause the lifting plate 22 of the rod body and the Y-axis fixing plate 17 to rise and fall, thereby completing the Z-axis displacement. Through the coordinated work of the displacement cylinder, the extension motor, the lifting motor and other components, the position of the detection component can be flexibly adjusted to meet the detection requirements of the microphone holes in different positions.
[0039] It should be noted that the integrated notebook microphone hole sealing inspection fixture designed by the present invention, when used, places the notebook computer shell on the placement slot 2, and the microphone hole on the computer shell side is aligned with the suction component 3. Start the booster cylinder 31, the output end of the booster cylinder 31 pushes the sliding connector 32 to slide on the slide rail 24, and the sliding connector 32 drives the air nozzle 34 to move until it reaches the microphone hole, and then starts the vacuum generator 2613, and the air pressure enters the microphone hole through the pipeline through the air nozzle 34 to start suction, so that a negative pressure environment is created inside the notebook shell. After reaching the preset negative pressure, the vacuum source is cut off by the solenoid valve 2714, and the pressure holding stage is entered. After that, the changes in the pressure value and the flow value can be recorded by the instrument monitoring the vacuum. If the pressure drop does not exceed the set 10% within a certain period of time, it means that the microphone hole is well sealed and the test is passed. If the pressure drop exceeds 10%, it indicates that there is a leak and the test fails. When performing a sealing test on the microphone hole on the top of the notebook, the displacement cylinder 9 will start to drive the upper template 5 to move to the test position, and then the upper template 5 will be lowered. The downward moving upper template 5 will drive the upper nozzle 11 connector 10 to move downward, and the distance member 12 will press down together against the shell to prevent the shell from shaking or shifting during detection. After the upper nozzle 11 reaches the top microphone hole, the vacuum generator 26 is connected to the interface of the upper nozzle 11 connector 10. At this time, the vacuum generator 26 is started, and the upper nozzle 11 will start to extract air to form a negative pressure. For detection, after reaching the preset negative pressure, the vacuum source is cut off by the solenoid valve 27, and the pressure holding stage is entered. Start monitoring.
