Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing equipment technology, and specifically relates to a visual testing device for encapsulated voids. Background Technology
[0002] In today's era of rapid technological advancement, electronic devices are constantly evolving towards miniaturization and integration, with packaging technology playing a crucial role. Especially for core components such as chips, packaging not only protects them from external environmental damage but also enables electrical connections and signal transmission. However, voids generated during the packaging process act like hidden "time bombs," seriously threatening the performance and reliability of electronic products.
[0003] Traditional inspection methods, such as manual visual inspection, are completely ineffective at detecting voids and defects inside packages because they cannot penetrate the packaging material to observe the internal structure. While automated optical inspection (AOI) has certain advantages in detecting surface defects in electronic components, it also cannot accurately and efficiently detect internal voids obscured by the package. Existing inspection technologies cannot accurately inspect the internal packaging process of the package, thus reducing inspection efficiency.
[0004] Therefore, a visual inspection device for encapsulated voids is needed to solve the problem that existing technologies cannot accurately and efficiently inspect the interior of the encapsulated body. Utility Model Content
[0005] The purpose of this invention is to provide a visual inspection device for encapsulated voids, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection device for encapsulating cavities, comprising an operating table, support legs, and a support frame. The support legs are fixedly installed at the bottom of the operating table, and the support frame is fixedly connected to the rear side of the operating table. A slide is fixedly installed on the top of the operating table, and a detection placement mechanism is slidably installed on the upper part of the slide. A matching mechanism is provided at the front of the support frame, and a pressure sensor is fixedly installed at the rear of the slide. The detection placement mechanism is aligned with the matching mechanism below it via the slide and the pressure sensor. A display screen is fixedly installed on the right side of the slide at the top of the operating table for data analysis and display of the detection placement mechanism and the matching mechanism.
[0007] It should be noted in the solution that the placement and testing mechanism includes a testing platform, a limiting seat, a placement slot and a sound wave transmitter. The testing platform is slidably installed on the upper part of the slide, the limiting seat is fixedly installed on the top of the testing platform, the placement slot is opened on the limiting seat, and the sound wave transmitter is fixedly installed inside the testing platform and located below the placement slot.
[0008] It is worth noting that the limiting seat is provided with a four-claw limiting structure for fixing and limiting the package.
[0009] Furthermore, it should be noted that the matching mechanism includes an electric telescopic rod, a mounting plate, a protective cover, and a sound wave receiver. The electric telescopic rod is fixedly installed on the upper part of the support frame, the mounting plate is fixedly installed on the bottom end of the electric telescopic rod, the protective cover is fixedly connected to the bottom of the mounting plate, and the sound wave receiver is fixedly installed on the bottom of the mounting plate and located inside the protective cover.
[0010] In a preferred embodiment, the inner diameter of the protective cover is matched to the size of the limiting seat, and the protective cover and the limiting seat are sealed together.
[0011] Compared with the prior art, the visual detection device for encapsulated voids provided by this utility model has at least the following beneficial effects:
[0012] The placement and detection mechanism facilitates stable and convenient placement and detection of the package. In conjunction with the matching mechanism, when detecting the package, a sound wave is emitted by a sound wave transmitter, guided through the package, and then received by a sound wave receiver. The received sound waves can be analyzed on the display screen, thereby accurately determining whether there are voids inside the package, thus improving the accuracy of the detection.

[0018] The present invention will be further described below with reference to the embodiments.
[0019] Please see Figure 1-4This utility model provides a visual inspection device for encapsulating voids, including an operating table 1, a support leg 2, and a support frame 3. The support leg 2 is fixedly installed at the bottom of the operating table 1, and the support frame 3 is fixedly connected to the rear side of the operating table 1. A slide 4 is fixedly installed on the top of the operating table 1, and a detection placement mechanism 5 is slidably installed on the upper part of the slide 4. A matching mechanism 6 is provided at the front of the support frame 3, and a pressure sensor 401 is fixedly installed at the rear of the slide 4. The detection placement mechanism 5 is aligned with the matching mechanism 6 below it through the slide 4 and the pressure sensor 401. A display screen 7 is fixedly installed on the right side of the slide 4 at the top of the operating table 1 for data analysis and display of the detection placement mechanism 5 and the matching mechanism 6.
[0020] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the placement and testing mechanism 5 includes a testing platform 501, a limiting seat 502, a placement groove 503, and an acoustic wave transmitter 504. The testing platform 501 is slidably installed on the upper part of the slide block 4. The limiting seat 502 is fixedly installed on the top of the testing platform 501. The placement groove 503 is opened on the limiting seat 502. The acoustic wave transmitter 504 is fixedly installed in the testing platform 501 and located below the placement groove 503. The limiting seat 502 is provided with a four-claw limiting structure for fixing and limiting the package.
[0021] In use, the qualified package is first placed in the limiting seat 502 for limiting, and the electric telescopic rod 601 is operated to make the protective cover 603 cooperate with the limiting seat 502 for detection and protection. At this time, the sound wave transmitter 504 is operated to emit sound waves, and the sound wave receiver 604 receives the sound waves. The received sound waves are analyzed on the display screen 7 to form a reference waveform of the qualified package. The detection table 501 slides on the slide 4. The contact between the detection table 501 and the pressure sensor 401 forms pressure data. At this time, the operation of the electric telescopic rod 601 can make the protective cover 603 slide downward, so that the protective cover 603 matches the limiting seat 502 and seals the protective cover 603 outside the limiting seat 502, thereby ensuring the accuracy of the detection.
[0022] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that the matching mechanism 6 includes an electric telescopic rod 601, a mounting plate 602, a protective cover 603, and a sound wave receiver 604. The electric telescopic rod 601 is fixedly installed on the upper part of the support frame 3. The mounting plate 602 is fixedly installed on the bottom end of the electric telescopic rod 601. The protective cover 603 is fixedly connected to the bottom of the mounting plate 602. The sound wave receiver 604 is fixedly installed on the bottom of the mounting plate 602 and located inside the protective cover 603. The inner diameter of the protective cover 603 is matched to the size of the limiting seat 502. The protective cover 603 and the limiting seat 502 are sealed together. A silicone sealing ring (not shown in the figure) is provided at the bottom of the protective cover 603, which contacts the limiting seat 502 to form a sealed cavity and isolate environmental noise.
[0023] In use, the operation of the electric telescopic rod 601 allows the protective cover 603 to slide downwards, thereby matching the protective cover 603 with the limiting seat 502 and sealing the protective cover 603 outside the limiting seat 502, thus ensuring the accuracy of the test. The sound wave signal received by the sound wave receiver 604 is compared and analyzed with the qualified spectrum on the display screen 7 to determine whether there are encapsulation voids inside the package, thereby improving the accuracy and convenience of the test.
[0024] Specifically, the acoustic wave transmitter 504 uses a piezoelectric ceramic transducer; the acoustic wave receiver 604 is coaxially aligned with the acoustic wave transmitter 504; the placement groove 503 and the package body are filled with ultrasonic coupling gel (not shown in the figure) and acoustic impedance matching encapsulation material.
[0025] This solution has the following working process: When this device is used to test the package, firstly, the qualified package is placed and limited within the limiting seat 502, and the electric telescopic rod 601 is operated so that the protective cover 603 cooperates with the limiting seat 502 to test and protect it. At this time, the sound wave transmitter 504 operates to emit sound waves, and the sound wave receiver 604 receives the sound waves. The received sound waves are analyzed on the display screen 7 to form a reference waveform for the qualified package. Then, the package is installed and limited on the limiting seat 502, and the test table 50... 1. Slide on slide block 4. Pressure data is generated through contact between detection stage 501 and pressure sensor 401. At this time, the operation of electric telescopic rod 601 can make protective cover 603 slide downward, so that protective cover 603 matches limit seat 502 and seals protective cover 603 outside limit seat 502, thereby ensuring the accuracy of detection. The sound wave signal received by sound wave receiver 604 is compared and analyzed with qualified reference waveform on display screen 7 to determine whether there is a sealing hole inside the package, thereby improving detection accuracy and convenience.
[0026] In summary: The placement and detection mechanism 5 facilitates stable and convenient placement and detection of the package, which works in conjunction with the matching mechanism 6. When detecting the package, sound waves are emitted by the sound wave transmitter 504, guided through the package, and then received by the sound wave receiver 604. The received sound waves can be analyzed through the display screen 7, thereby accurately determining whether there are voids inside the package, thus improving the accuracy of the detection.
