Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic testing machine for integrated circuit boards. Background Technology

[0002] Integrated circuit boards, as a revolutionary technology, have greatly promoted the miniaturization and visualization of circuits, playing a crucial role in realizing the large-scale production of fixed circuits and optimizing the layout of electronic devices.

[0003] Given their widespread use in daily life, numerous manufacturers specializing in integrated circuit board production have emerged. However, as highly precise electronic components, even the slightest deviation in specifications can lead to a significant decrease in performance or even complete malfunction. Furthermore, integrated circuit boards are densely packed with numerous tiny solder joints; manually connecting and testing each one is clearly insufficient to meet the stringent efficiency and precision requirements of modern production. Therefore, comprehensive and rigorous testing of integrated circuit boards before they leave the factory and are put into practical use is crucial to ensure their quality and reliability.

[0073] In view of the deficiencies of the existing technology, the applicant, based on years of practical experience and professional knowledge in this field, and in conjunction with the application of theoretical principles, has actively conducted research and innovation in order to create a technology that can solve the deficiencies of the existing technology. After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.

[0074] Please refer to Figure 1-9 This utility model provides a highly innovative automatic testing machine for integrated circuit boards, which includes several key components such as a test chamber 1, a water-cooled chamber 2, a water-cooled plate 3, and test boards 4. The test chamber 1 is composed of a lower chamber 101 and an upper cover 102. The lower chamber 101 has an internal cavity with an opening directly connected to it; the upper cover 102 cleverly covers this opening, forming a closed space.

[0075] The water-cooled plate 3 is carefully placed inside the cavity of the lower housing 101. Its two opposing surfaces bear the important task of fixing the integrated circuit board 24 to be tested, and at the same time, they are responsible for efficiently dissipating heat from the integrated circuit board 24. In order to build a complete cooling system, the water-cooled box 2 is connected to the water-cooled plate 3 through a precision circulation pipe 5. This design allows the coolant to be smoothly injected into the water-cooled plate 3 and effectively recycled back into the water-cooled box 2 after completing its heat dissipation task, thus forming a complete coolant circulation system.

[0076] In addition, a workbench 6 is cleverly set on the top cover 102, which is further equipped with a probe module 7 that is electrically connected to the integrated circuit board 24. The test board 4 is securely mounted on the workbench 6 and in close contact with the probe module 7, thereby ensuring that a stable and reliable electrical connection can be established between them.

[0077] From the perspective of structural design and functional implementation, this embodiment of the invention cleverly incorporates a water-cooled plate 3 inside the cavity of the lower housing 101. This design aims to effectively manage the heat generated by the integrated circuit board 24 during testing. Subsequently, a closed cooling circulation system is constructed through the connection of the circulation pipe 5 with the water-cooled box 2, thereby further improving heat dissipation efficiency.

[0078] Based on this, the integrated circuit board 24 to be tested is securely fixed on two opposing surfaces of the water-cooled plate 3. This arrangement not only ensures that the integrated circuit board 24 can receive timely and uniform heat dissipation support during the test, but also effectively reduces the risk of damage to the integrated circuit board 24 due to excessive heat accumulation.

[0079] Through this innovative design, the water-cooled plate 3 can efficiently absorb and remove the heat generated by the integrated circuit board 24 during operation, thereby significantly improving the factory quality control level of the integrated circuit board 24 and ensuring that each circuit board meets the predetermined performance standards. At the same time, this improvement also greatly enhances the market appeal of this automated testing equipment, laying a solid foundation for its widespread application in the field of integrated circuit board testing.

[0080] In conclusion, the implementation of this utility model not only helps to improve the product quality of integrated circuit boards, but also plays a positive role in promoting the market and popularization of this testing equipment.

[0081] Please refer to this again. Figure 4This allows for a deeper understanding of a specific implementation detail of this utility model. In this embodiment, a hinge connection mechanism is cleverly employed to tightly connect the upper cover 102 to the lower housing 101. This design not only ensures that the upper cover 102 can be opened and closed flexibly, but also greatly improves the structural stability and durability of the entire testing machine.

[0082] Of particular note is that, in order to further enhance the convenience and stability of the upper cover 102 during use, this utility model also features a multi-angle positioning support component 8 carefully designed between the upper cover 102 and the lower housing 101. The purpose of this component is to provide stable support when the upper cover 102 is opened to different angles, thereby preventing the upper cover 102 from accidentally closing or shaking due to its own weight or external forces, effectively ensuring the continuity and safety of the testing process.

[0083] The working principle of the multi-angle positioning support component 8 is quite ingenious: it can automatically adjust and lock the position of the top cover 102 at different stages of opening through internal mechanical structures (such as a multi-section interlocking structure similar to an umbrella pole) or elastic elements, so that it can stably stay at the required angle. In this way, testers can freely adjust the opening angle of the top cover 102 as needed, so as to facilitate the installation, testing, and result observation of integrated circuit boards.

[0084] In summary, by incorporating a hinge connection and a multi-angle positioning support assembly 8 between the upper cover 102 and the lower housing 101, this invention not only improves the structural stability and durability of the testing machine but also greatly enhances its convenience and flexibility during use. This innovative design undoubtedly provides a more efficient, safe, and reliable solution for the automated testing of integrated circuit boards.

[0085] Please refer to this again. Figure 7 and 9 This allows for a deeper understanding of another important implementation detail in the embodiments of this utility model. In this embodiment, the functionality of the automatic integrated circuit board testing machine is further enriched, and a comprehensive upgrade of heat management during the testing process is achieved by cleverly introducing the air-cooling component 9.

[0086] The air-cooling component 9 is carefully positioned within the lower chamber 101 cavity of the test chamber 1, cleverly located at the bottom of the water-cooling plate 3. This layout aims to fully utilize the advantages of combining air and water cooling to form a more efficient and comprehensive heat dissipation system. The air-cooling component 9 generates directional airflow through internal fans or blowers, effectively carrying away heat from the lower chamber 101 cavity and expelling it from the test machine through a dedicated exhaust channel.

[0087] When the integrated circuit board 24 generates a large amount of heat during testing, the water-cooled plate 3 first directly dissipates and cools the integrated circuit board 24 through the circulation of its internal coolant. At the same time, the air-cooled component 9 provides additional heat dissipation support below, further removing heat from the cavity through the generated airflow, thereby accelerating the entire heat dissipation process and improving heat dissipation efficiency.

[0088] This innovative design not only significantly improves the stability of the testing machine under long-term, high-intensity testing, but also effectively extends the service life of the integrated circuit board 24 and other electronic components inside the testing machine. Through the organic combination of air cooling and water cooling, this invention achieves precise control of heat management during the testing process, providing a more efficient and reliable solution for the automated testing of integrated circuit boards.

[0089] In summary, by introducing the air-cooling component 9 and cleverly placing it at the bottom of the water-cooling plate 3, this invention further improves the heat dissipation performance of the automatic integrated circuit board testing machine, providing strong assurance for the continuity and accuracy of the testing process. This innovative design undoubtedly brings more advanced and efficient technical means to the field of integrated circuit board testing.

[0090] Please refer to Figure 10-11 This allows for a deeper understanding of another key implementation detail in this utility model embodiment. In this embodiment, a cleverly designed fixing mechanism between the water-cooled plate 3 and the lower housing 101 is achieved. Through the perfect combination of the hook 10 and the buckle groove 11, the water-cooled plate 3 is securely installed in the lower housing 101.

[0091] Specifically, hooks 10 are carefully designed on the opposite sides of the water-cooled plate 3, while the inner wall of the lower housing 101 is cleverly designed with buckle grooves 11 corresponding to the positions of the hooks 10. The shape of these buckle grooves 11 matches the hooks 10, which can ensure that the hooks 10 can be tightly embedded in them when fastened and are not easy to fall off.

[0092] When it is necessary to fix the installed water-cooled plate 3, simply align the hook 10 on it with the snap-fit ​​groove 11 of the lower housing 101, and then press gently to make the hook 10 rotate and smoothly snap into the snap-fit ​​groove 11. Once the hook 10 is fully engaged in the snap-fit ​​groove 11, they will be tightly locked together, thereby firmly fixing the water-cooled plate 3 in the lower housing 101. Figure 10 This indicates the locked state. Figure 11 This indicates the unlocked state. This fixing method is not only simple and easy to implement, but also very secure, effectively preventing the water-cooled plate 3 from shaking or shifting during testing.

[0093] Furthermore, the fixing mechanism of the hook 10 and the latching slot 11 facilitates the disassembly and replacement of the water-cooled plate 3. When it is necessary to clean, repair, or replace the water-cooled plate 3, or to disassemble the tested integrated circuit board 24, simply press the hook 10 gently to release it from the latching slot 11, and the water-cooled plate 3 along with the integrated circuit board 24 attached to it can be easily removed from the lower housing 101. This design not only improves the operability and maintainability of the testing machine, but also reduces operating time and maintenance costs.

[0094] In summary, by cleverly designing the fixing mechanism of the hook 10 and the snap-fit ​​groove 11, this utility model achieves stable installation and convenient disassembly of the water-cooled plate 3 within the lower housing 101. This innovative design not only improves the structural stability and durability of the testing machine but also greatly facilitates subsequent maintenance and replacement work.

[0095] Please refer to this again. Figure 10-11 In one embodiment of this example, the connection method between the water-cooled plate 3 and the hook 10 is further explained. By introducing the pivot 12 and the first handle 13, the hook 10 is rotatably hinged on the water-cooled plate 3, which greatly improves the convenience of operation.

[0096] Specifically, the hook 10 features a cleverly designed pivot hole, allowing the pivot 12 to pass smoothly through it, thus tightly connecting the hook 10 to the water-cooling plate 3. More advanced is the fact that this connection is not fixed; instead, the pivot 12 enables the hook 10 to be rotatably hinged relative to the water-cooling plate 3. This means that the hook 10 can rotate freely within a certain range to meet the requirements of engaging or disengaging from the latching slot 11.

[0097] To further enhance ease of operation, a first handle 13 is carefully designed into the hook component 10. This design allows testers to easily press or grip the first handle 13, and the hook component 10 can be engaged or disengaged through a simple rotation. The shape and size of the first handle 13 have been carefully considered, conforming to ergonomic principles and facilitating one-handed operation by testers, thereby greatly improving work efficiency.

[0098] In practical applications, when the water-cooling plate 3 needs to be installed, the tester can press the first handle 13, rotate the hook 10 to a suitable angle, and then easily lock it into the latching slot 11 of the lower housing 101. Similarly, when the water-cooling plate 3 needs to be removed, simply hold the first handle 13 and rotate the hook 10 slightly to make it pop out of the latching slot 11. This design not only simplifies the installation and disassembly process but also reduces the difficulty of operation and time costs.

[0099] In summary, by introducing the innovative design of the pivot 12 and the first handle 13, this utility model achieves rotatable hinge and convenient operation of the hook 10 on the water-cooled plate 3. This unique design improves the structural flexibility and ease of use of the testing machine.

[0100] Please refer to points 1-2 and 4 again, and combine them with other relevant information. Figure 12 This allows for a comprehensive understanding of another key innovation in this utility model embodiment. In this embodiment, the structure of the upper cover 102 is carefully designed. By introducing the second handle 14 and the ingenious combination of the double elbow clamping mechanism, efficient and stable clamping and convenient replacement of the test board 4 are achieved.

[0101] Specifically, a second handle 14 is cleverly designed on the top cover 102. This design not only conforms to ergonomic principles, facilitating one-handed operation by the tester, but also is closely connected to the double-elbow lever clamping mechanism. The double-elbow lever clamping mechanism, as an advanced mechanical structure, is renowned for its stable and reliable clamping performance and convenient operation. By operating the second handle 14, the tester can easily drive the double-elbow lever clamping mechanism to clamp or release the test board 4.

[0102] Figure 1 and Figure 2 The images show two different positions of the second handle 14: locked and unlocked. When the second handle 14 is locked (e.g., ...), ... Figure 2 As shown), the double-elbow clamping mechanism tightly clamps the test board 4, ensuring that it will not shake or shift due to external forces during testing, thereby greatly improving the stability and accuracy of the testing process. When the second handle 14 is in the unlocked state (as shown...), Figure 1 As shown), the double elbow clamping mechanism automatically releases the clamp on the test board 4, allowing the tester to easily remove or replace different test boards 4 to meet different testing needs.

[0103] Test boards 4, as important tools for testing the performance, functionality, and reliability of integrated circuit boards 24, play a crucial role in the production and quality control of integrated circuit boards. They simulate real-world working environments to conduct comprehensive tests on integrated circuit boards 24, including electrical performance testing, functional verification, reliability assessment, and other aspects, to ensure their stability and reliability in practical applications.

[0104] In summary, by introducing the innovative design of the second handle 14 and the double elbow clamping mechanism, this utility model not only achieves efficient and stable clamping of the test board 4, but also greatly simplifies the operation process of replacing the test board 4.

[0105] Please refer to this again. Figure 12This allows for a more detailed understanding of the specific structure and working principle of the double elbow clamping mechanism in this embodiment. In this ingenious design, the double elbow clamping mechanism achieves stable clamping and convenient operation of the test board 4 through a series of precise mechanical connections.

[0106] First, the connecting rod 15, as one of the core components of the double elbow clamping mechanism, is closely connected to the second handle 14. By operating the second handle 14, the tester can indirectly control the movement of the connecting rod 15, thereby driving the entire double elbow clamping mechanism to work.

[0107] A connecting frame 16 is fixedly connected to the connecting rod 15. This connecting frame acts as a bridge, transmitting the movement of the connecting rod 15 to the elbows 17 on both sides. The connecting frame 16 is reasonably designed and robust, ensuring the stability and reliability of the entire clamping mechanism during operation.

[0108] Two elbow levers 17 are hinged to both sides of the connecting frame 16. As key components of the double elbow lever clamping mechanism, the elbow levers 17 possess excellent mechanical properties and motion characteristics. They are connected to the connecting frame 16 via hinges and can move in a coordinated manner under the drive of the connecting rod 15.

[0109] Each elbow 17 is hinged to a clamping block 18 at its end. These two clamping blocks 18 are respectively located on both sides of the test board 4, and can clamp the test board 4 when they come close to each other. The design of the clamping blocks 18 takes into full account the size and shape of the test board 4, ensuring the stability and reliability of the clamping process.

[0110] Furthermore, each clamping block 18 is mounted on a corresponding slide rail 19. The slide rail 19 provides a stable movement trajectory for the clamping blocks 18, allowing them to slide along the slide rail 19 under the drive of the second handle 14. This design not only simplifies the structure of the clamping mechanism but also improves its motion accuracy and stability.

[0111] In summary, the double-elbow clamping mechanism in this embodiment achieves efficient and stable clamping of the test board 4 through the precise cooperation of the connecting rod 15, connecting frame 16, elbow 17, clamping block 18, and slide rail 19. The tester can easily control the clamping mechanism to perform clamping or releasing operations simply by operating the second handle 14, greatly improving the convenience and efficiency of the testing process.

[0112] Please refer to this again. Figure 12 This study aims to further explore the precise fit between the double-elbow clamping mechanism and the test board 4 in this embodiment. This design not only improves the stability and reliability of the clamping mechanism but also ensures the accurate positioning and secure clamping of the test board 4 during the testing process.

[0113] Guide posts 20 are cleverly placed on both sides of the test board 4. These guide posts 20 serve as positioning elements, guiding the movement of the clamping block 18 and limiting the position of the test board 4. They are reasonably designed and robust, capable of withstanding various forces and torques that may be generated during the test, ensuring the stability of the test board 4.

[0114] Meanwhile, guide grooves 21 are formed on the clamping block 18 corresponding to the positions of the guide posts 20. The shape and size of these guide grooves 21 match the guide posts 20, allowing the guide posts 20 to smoothly engage within them. When the clamping block 18 slides along the slide rail 19 under the drive of the second handle 14, the guide posts 20 move along the guide grooves 21, thereby pressing down and locking the test board 4.

[0115] The advantage of this design is that it not only ensures the stability and accuracy of the test board 4 during the clamping process, but also allows for precise control of the downward pressure position of the test board 4 through the cooperation of the guide post 20 and the guide groove 21. In this way, even under different testing conditions, the test board 4 can always maintain the correct position and orientation, thus ensuring contact with the probe module 7 and guaranteeing the accuracy and reliability of the test results.

[0116] Furthermore, the design of the guide groove 21 is flexible, meaning its width can be appropriately increased to accommodate test boards 4 with guide posts 20 of different sizes and shapes. This flexibility allows the double elbow clamping mechanism in this embodiment to be widely used in various types of integrated circuit board testing applications, improving its versatility and practicality.

[0117] In summary, the double elbow clamping mechanism in this embodiment achieves efficient, stable clamping and precise positioning of the test board 4 through the precise cooperation of the guide post 20 and the guide groove 21. This design not only improves the convenience and efficiency of the testing process, but also provides a more reliable technical guarantee for the production and quality control of integrated circuit boards.

[0118] Please refer to Figure 13-15 As can be seen in this embodiment, the automatic integrated circuit board testing machine features an innovative design: the rotating support frame 22 and its ingenious integration with the lower housing 101. This design not only enhances the functionality and flexibility of the testing machine but also provides testers with a more convenient and efficient testing experience.

[0119] Specifically, the rotating support frame 22, as an important component of the testing machine, is securely installed in a suitable position on the testing machine. Its main function is to provide rotational support, enabling the lower housing 101 to rotate around the rotating axis 23.

[0120] Rotating shafts 23 are cleverly arranged on both sides of the lower housing 101. These rotating shafts not only serve as key components connecting the lower housing 101 and the rotating support frame 22, but also ensure the smoothness and reliability of the rotational movement. They are precisely installed at corresponding positions on the rotating support frame 22, allowing the lower housing 101 to rotate freely under the support of the rotating support frame 22.

[0121] This design allows testers to easily adjust the tilt angle of the lower housing 101 to meet various testing needs. For example, in some testing scenarios, testers may need to place the test board at different angles to obtain chip performance data at different angles. In this case, testers can achieve this simply by gently rotating the lower housing 101.

[0122] It is worth mentioning that the materials and manufacturing processes of the rotating support frame 22 and the rotating shaft 23 have also been carefully selected and optimized. They are made of high-strength, corrosion-resistant materials, ensuring the stability and reliability of the testing machine during long-term use. At the same time, the manufacturing process has also undergone strict control and inspection to ensure the accuracy and smoothness of the rotational motion.

[0123] In summary, the integrated circuit board automatic testing machine in this embodiment achieves flexible rotation and tilt angle adjustment of the lower housing 101 through the innovative design of the rotating support frame 22 and the rotating shaft 23. This design not only improves the convenience and efficiency of testing, but also provides testers with a more diverse and personalized testing experience.

[0124] In this innovative design, the integrated circuit board automatic testing machine further incorporates a rotary drive mechanism, which is cleverly mounted on the rotary support frame 22, and its drive rod is connected to one of the rotating shafts 23. This design not only greatly improves the automation level of the testing machine but also brings users a more intelligent and efficient testing experience.

[0125] As one of the core components of the testing machine, the rotary drive mechanism undertakes the important task of driving the rotary shaft 23 to rotate. It adopts advanced drive technology and a precision transmission mechanism to ensure the smoothness, accuracy and reliability of the rotational motion.

[0126] Through its transmission connection with the rotating shaft 23, the rotary drive mechanism can easily achieve the rotational movement of the lower housing 101. Users can remotely control the rotary drive mechanism to adjust the tilt angle of the lower housing 101 simply by using the control panel or other operating methods.

[0127] The advantage of this design is that it greatly simplifies the operation steps during the testing process, improving the convenience and efficiency of testing. Users do not need to manually rotate the lower housing 101; they can adjust the tilt angle with a simple operation, thus saving testing time and costs.

[0128] Furthermore, the rotary drive mechanism also possesses certain intelligent functions. It can automatically adjust the rotation angle and speed according to user settings or testing requirements, achieving a more precise and stable testing process. Simultaneously, it can be linked and controlled with other testing equipment to accomplish more complex and diverse testing tasks.

[0129] It is worth mentioning that the materials and manufacturing process of the rotary drive mechanism have also been carefully selected and optimized. It is made of high-strength, wear-resistant materials, ensuring stability and reliability during long-term use. At the same time, the manufacturing process has undergone strict control and inspection, ensuring the accuracy and durability of the transmission mechanism.

[0130] In summary, the integrated circuit board automatic testing machine in this embodiment achieves automated rotation and precise adjustment of the tilt angle of the lower housing 101 through the innovative design of a rotary drive mechanism. This design not only improves the convenience and efficiency of testing but also provides users with a more intelligent and efficient testing experience.

[0131] Although this application uses terms such as test chamber and water-cooled plate frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0132] This utility model provides an automatic integrated circuit board testing machine. By installing a water-cooled plate within the cavity of the lower housing, and connecting the water-cooled plate to a water-cooled chamber via a circulation pipeline, the integrated circuit board to be tested is fixed to the opposite surfaces of the water-cooled plate. This allows the water-cooled plate to dissipate heat from the integrated circuit board, preventing excessive heat buildup and damage. This improvement not only significantly enhances the quality control level of integrated circuit boards before they leave the factory, ensuring that each integrated circuit board meets the predetermined performance standards, but also further enhances the market appeal of this automated testing machine, laying a solid foundation for its widespread application in the field of integrated circuit board testing.

[0133] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
