After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.

[0062] Please refer to Figure 1-4 This utility model embodiment provides an automatic testing machine with a quick board replacement function, including a test box 1 and a test board 2;

[0063] Specifically, the internal space of the test chamber 1 is designed to house the integrated circuit board 3 to be tested. A workbench 4 is installed on top of the test chamber 1, and a probe module 5 is mounted on the workbench 4, which can make an electrical connection with the integrated circuit board 3. Furthermore, the test board 2 is cleverly placed on the workbench 4, and through direct contact with the probe module 5, the necessary electrical connection path is established.

[0064] Furthermore, a handle 6 and a double-elbow lever clamping mechanism are cleverly designed on the top area of ​​the test box 1. The handle 6 and the double-elbow lever clamping mechanism are connected by a mechanical structure, allowing the operator to simply operate the handle 6 to drive the double-elbow lever clamping mechanism to clamp or release the test board 2.

[0065] The innovation of this embodiment lies in the innovative configuration of an interconnected handle 6 and a double-elbow lever clamping mechanism on the top area of ​​the test chamber 1. This design allows the operator to effectively control the double-elbow lever clamping mechanism simply by operating the handle 6, thereby quickly and securely clamping or releasing the test board 2 placed on the top worktable 4 of the test chamber 1. This improvement not only greatly enhances the convenience and speed of the test board 2 replacement process, thus significantly improving overall work efficiency, but also provides operators with a smoother and more efficient operating experience, undoubtedly representing a significant advancement in the design of automated testing equipment.

[0066] Please refer to this again. Figure 2 To gain a deeper understanding of a specific implementation detail of this embodiment, the double elbow lever clamping mechanism exhibits its complex and ingenious construction. The core component of this mechanism includes a connecting rod 7, which is carefully designed to connect to the handle 6, thereby ensuring a stable and flexible linkage between the two.

[0067] Furthermore, a connecting frame 8 is securely mounted on the connecting rod 7. This design not only enhances the overall stability of the mechanism but also provides necessary support for subsequent mechanical actions. Hinged elbows 9 are respectively installed on both sides of the connecting frame 8. These elbows 9, like robotic arms, can swing and extend flexibly through precise hinge design, providing a powerful power source for subsequent clamping actions.

[0068] At the end of each lever 9, a clamping block 10 is cleverly connected. These two clamping blocks 10, as key components directly acting on the test board 2, are designed to ensure sufficient clamping force while preventing any damage to the test board 2. More importantly, these two clamping blocks 10 are respectively mounted on corresponding slide rails 11. This design allows the clamping blocks 10 to slide smoothly and precisely along the slide rails 11 under the drive of the handle 6, thereby achieving rapid and stable clamping or releasing actions on the test board 2.

[0069] In summary, through this series of meticulous designs and layouts, the double elbow clamping mechanism in this embodiment not only achieves efficient and safe clamping of the test board 2, but also greatly improves the ease of operation and work efficiency of the entire automated testing equipment.

[0070] Please refer to this again. Figure 2 This allows for a deeper understanding of a unique design in this embodiment. In this embodiment, the test board 2 and its clamping mechanism have undergone more refined processing.

[0071] Specifically, guide posts 12 are cleverly installed on both sides of the test board 2. These guide posts 12 not only serve the functions of positioning and support, but also provide precise guidance for the subsequent clamping action.

[0072] Meanwhile, guide grooves 13 are specially designed on the clamping block 10 for the positions of the guide posts 12. The shape and size of these guide grooves 13 perfectly match the guide posts 12, ensuring that the guide posts 12 can be accurately engaged. When the operator drives the clamping block 10 to slide along the slide rail 11 using the handle 6, the guide posts 12 will move smoothly and in a controlled manner under the guidance of the guide grooves 13. This design not only ensures the accuracy and stability of the clamping action, but also effectively prevents the test board 2 from shifting or shaking during the clamping process.

[0073] More importantly, as the guide post 12 moves within the guide groove 13, the clamping block 10 gradually approaches and ultimately locks the test board 2 securely. This process is both fast and efficient, greatly improving the ease of operation and work efficiency of the automated testing equipment. Simultaneously, the precise fit between the guide post 12 and the guide groove 13 ensures the stability and safety of the test board 2 in the clamped state, providing a solid guarantee for subsequent testing.

[0074] In conclusion, this unique design in this embodiment not only demonstrates a high degree of innovation and practicality, but also injects new vitality into the development of automated testing equipment.

[0075] Please observe carefully again. Figure 2To fully understand the innovative design of precise positioning and fixation between the workbench 4 and the test board 2 in this embodiment, guide positioning pins 14 are cleverly installed at appropriate positions on the workbench 4. These guide positioning pins 14, as key positioning elements, have been carefully designed and calculated in terms of shape, size, and distribution to ensure that they can accurately match the corresponding structures on the test board 2.

[0076] Correspondingly, guide positioning holes 15 that perfectly match the guide positioning pins 14 are also provided on the test board 2. The position, shape and size of these guide positioning holes 15 correspond strictly to the guide positioning pins 14, thereby ensuring that the test board 2 can quickly and accurately find its correct position during installation.

[0077] When the test board 2 is placed on the worktable 4, the guide positioning pin 14 naturally inserts into the corresponding guide positioning hole 15. This process not only provides stable and reliable support for the test board 2, but also ensures its precise positioning on the worktable 4. This design greatly simplifies the installation process of the test board 2, reduces errors and malfunctions caused by positional deviations, thereby improving the accuracy and reliability of the entire automated testing equipment.

[0078] Furthermore, the matching design of the guide positioning pin 14 and the guide positioning hole 15 enhances the stability of the test board 2 on the worktable 4, making it less prone to shaking or shifting during testing. This feature is crucial for ensuring the accuracy and consistency of test results and provides a solid guarantee for subsequent testing work.

[0079] In summary, this innovative design in this embodiment not only demonstrates a high degree of professionalism and precision, but also makes a significant contribution to improving the performance and optimizing the efficiency of automated testing equipment.

[0080] In one specific and creative embodiment of this invention, the guide positioning pins 14 on the worktable 4 are designed in a more detailed and differentiated manner. Specifically, guide positioning pins 14 are provided at opposite ends of the worktable 4, but the guide positioning pins 14 at these two ends differ in size and / or shape.

[0081] The starting point of this design is that the test board 2 may have certain asymmetries in structure and function, or need to follow a specific orientation during installation. Therefore, by setting guide positioning pins 14 of different sizes and / or shapes at both ends of the workbench 4, it can be ensured that the test board 2 can be placed accurately in the predetermined direction and position during installation, thus preventing mistake-proofing.

[0082] Specifically, when the test board 2 is placed on the worktable 4, the guide positioning hole 15 at one end matches and inserts into the guide positioning pin 14 of the corresponding size, while the guide positioning hole 15 at the other end matches and inserts into the guide positioning pin 14 of another size or shape. This process not only provides precise positioning and support for the test board 2, but also ensures its stability and orientation on the worktable 4.

[0083] Furthermore, this differentiated design helps prevent misoperation or misalignment of the test board 2 during installation, thereby further improving the accuracy and reliability of the automated testing equipment. Simultaneously, due to the precise matching of the guide positioning pin 14 and the guide positioning hole 15, the test board 2 is more firmly and stably fixed on the worktable 4, providing a solid guarantee for subsequent testing work.

[0084] In summary, this innovative design in this embodiment not only demonstrates a high degree of professionalism and precision, but also makes a significant contribution to improving the performance and optimizing the efficiency of automated testing equipment. In particular, it shows its unique advantages and value when dealing with test boards with specific orientations or structural asymmetries.

[0085] Please refer to this again. Figure 3-4 In one embodiment of this invention, the test box 1 is innovatively divided into two main parts: a lower box body 101 and an upper cover 102.

[0086] The lower housing 101 constitutes the main structure of the test chamber 1, and it has a cavity and an opening. The cavity is carefully designed to accommodate the integrated circuit board 3 to be tested, while the opening is connected to the cavity, providing the necessary channel for the insertion and removal of the integrated circuit board 3.

[0087] The top cover 102 serves as the top sealing structure of the lower housing 101, tightly covering the opening to ensure the airtightness and safety of the test chamber 1. This design not only effectively prevents harmful substances such as external dust and moisture from damaging the integrated circuit board 3, but also provides a stable and controllable environment for the testing process.

[0088] What's even more unique is that in this embodiment, the workbench 4, handle 6, and double elbow clamping mechanism are all cleverly positioned on the top of the cover 102. This layout not only brings these key components closer to the integrated circuit board 3 to be tested, thereby improving the convenience and efficiency of operation, but also makes the entire test box 1 more compact and integrated.

[0089] Specifically, the workbench 4 provides the necessary operating platform, enabling the test board 2 to be stably placed and electrically connected to its probe module 5. The handle 6 serves as a control tool for the operator, allowing for simple operation to drive the double-elbow clamping mechanism to clamp or release the test board 2. The double-elbow clamping mechanism, with its precise and stable clamping action, ensures the stability and reliability of the test board 2 during the testing process.

[0090] In summary, this innovative design not only demonstrates a high degree of professionalism and precision but also makes a significant contribution to the structural optimization and performance improvement of automated testing equipment. By integrating the workbench 4, handle 6, and double elbow clamping mechanism onto the top of the cover 102, this embodiment simplifies the testing process, improves testing efficiency, and provides operators with a more comfortable and convenient operating experience.

[0091] Please refer to this again. Figure 4 This study aims to explore in depth the unique design of the connection between the upper cover 102 and the lower housing 101 of the test chamber 1 in this embodiment. In this particular embodiment, a hinge connection is innovatively used to achieve a flexible and stable connection between the upper cover 102 and the lower housing 101.

[0092] The hinged design allows the top cover 102 to rotate around a fixed axis, thus easily opening or closing the test chamber 1. This design not only provides users with great operational convenience but also ensures the stability and safety of the top cover 102 during opening or closing.

[0093] What's even more unique is that, to further enhance the stability and support of the upper cover 102 in the open state, a multi-angle positioning support assembly 20 is cleverly set between the upper cover 102 and the lower housing 101. This assembly can provide precise support and positioning for the upper cover 102 when it is opened to different angles, thereby ensuring that the upper cover 102 can be stably stopped in any desired position.

[0094] The multi-angle positioning support component 20 is designed to meet the diverse needs of users in actual operation. Whether it is for fine-tuning or for quickly checking the inside of the test chamber 1, users can adjust the opening angle of the top cover 102 as needed and ensure its stability through the multi-angle positioning support component 20.

[0095] Furthermore, the addition of the multi-angle positioning support component 20 enhances the overall structural strength and durability of the test chamber 1. During long-term use, it effectively reduces wear and damage to the top cover 102 caused by frequent opening and closing, thereby extending the service life of the test chamber 1.

[0096] In summary, this innovative design not only demonstrates a high degree of professionalism and practicality but also makes a significant contribution to the ease of operation, stability, and durability of automated testing equipment. By employing hinged connections and multi-angle positioning support components 20, this embodiment successfully solves the problem of insufficient stability of traditional test chambers in the open state, providing users with a superior operating experience.

[0097] Please refer to Figure 5-7 This allows for a deeper understanding of another innovative design of the automated test machine with rapid board replacement capability in this embodiment: the water-cooling system. This system consists of three core components: a water-cooling plate 18, a circulation pipeline 19, and a water-cooling box 16. It aims to efficiently solve the heat dissipation problem generated by the integrated circuit board 3 during high-intensity testing.

[0098] The water-cooled plate 18 is carefully designed and placed inside the cavity of the test chamber 1, with its two opposing surfaces specifically designed to fix the integrated circuit board 3. This design not only ensures the stability and safety of the integrated circuit board 3, but more importantly, the water-cooled plate 18 can fit tightly against the integrated circuit board 3, and through the circulation of coolant inside, it can quickly remove the heat generated by the test, thereby achieving effective heat dissipation for the integrated circuit board 3.

[0099] The circulation pipe 19 acts as a bridge connecting the water-cooled plate 18 and the water-cooled box 16, responsible for transporting coolant from the water-cooled box 16 to the water-cooled plate 18. After completing its heat dissipation task, it returns the coolant to the water-cooled box 16 for further cooling and recycling. This design not only improves the utilization rate of the coolant but also ensures the continuous and stable operation of the water-cooled heat dissipation system.

[0100] The water-cooled tank 16, as the "heart" of the entire water-cooling system, is responsible for storing, cooling, and circulating the coolant. It is equipped with specialized cooling devices and a circulation system to ensure the coolant is always kept within a suitable temperature range, thereby maximizing heat dissipation efficiency.

[0101] More notably, the water-cooling system in this embodiment adopts a modular design, allowing components such as the water-cooling plate 18, circulation pipes 19, and water-cooling box 16 to be easily disassembled and replaced. This design not only greatly facilitates system maintenance and upgrades but also enables the entire automated testing machine to maintain efficient and stable heat dissipation performance when dealing with different testing requirements and board replacements.

[0102] In summary, the water-cooling system in this embodiment not only demonstrates a high degree of innovation and practicality, but also makes a significant contribution to improving the performance and optimizing the efficiency of the automated test machine. Through an efficient, stable, and maintainable water-cooling method, this embodiment successfully solves the heat dissipation problem of the integrated circuit board 3 during high-intensity testing, providing a solid guarantee for the long-term stable operation of the automated test machine.

[0103] Please refer to this again. Figure 7 This allows for a deeper understanding of another innovative design of the automated test machine with quick board replacement functionality in this embodiment: the integration of the air-cooling component 17. This design not only further enhances the heat dissipation capacity inside the test chamber 1 but also provides a more reliable guarantee for the stable operation of the integrated circuit board 3 under high-intensity testing environments.

[0104] The air-cooling component 17 is cleverly positioned within the cavity of the test chamber 1, at the bottom of the water-cooling plate 18. This arrangement allows the air-cooling component 17 to fully utilize the space within the cavity, while simultaneously complementing the heat dissipation effect of the water-cooling plate 18. Through its internal fan or air duct design, the air-cooling component 17 generates a stable airflow, rapidly removing heat generated by the integrated circuit board 3 and its surroundings, and expelling it outside the test chamber 1 through its ventilation holes or other exhaust devices.

[0105] Compared to the water-cooled plate 18, the air-cooled assembly 17 has a different heat dissipation mechanism and advantages. The water-cooled plate 18 mainly removes heat through direct contact between the coolant and the integrated circuit board 3, while the air-cooled assembly 17 achieves heat transfer and dissipation through airflow. These two heat dissipation methods work together to more comprehensively and efficiently solve the heat dissipation problem of the integrated circuit board 3 during high-intensity testing.

[0106] Furthermore, the addition of the air-cooling component 17 enables the entire automated test machine to have a more flexible and adjustable heat dissipation solution when dealing with different test requirements and board replacements. For example, when the test power is low or the heat dissipation requirement is not high, the air-cooling component 17 can be used for heat dissipation alone; while when the test power is high or the heat dissipation requirement is high, the water-cooling plate 18 and the air-cooling component 17 can be activated simultaneously to achieve a more efficient heat dissipation effect.

[0107] In summary, the integration of the air-cooled component 17 in this embodiment not only further enhances the heat dissipation capacity inside the test chamber 1, but also makes a significant contribution to the performance improvement and efficiency optimization of the automatic testing machine. Through its cooperation with the water-cooled plate 18, this embodiment successfully constructs a highly efficient, stable, and adjustable heat dissipation system.

[0108] In one specific and innovative embodiment of this invention, the water-cooled chamber 16 employs a variable frequency water-cooled chamber, which serves as a key heat dissipation component of the automatic testing machine. This design not only further improves the performance and efficiency of the heat dissipation system but also provides the automatic testing machine with a more flexible and adjustable heat dissipation solution when dealing with different testing requirements and heat dissipation conditions.

[0109] The core advantage of the variable frequency water-cooled box lies in its built-in variable frequency technology. By intelligently adjusting the speed of the water pump and cooling fan, the variable frequency water-cooled box can adjust the circulation speed of the coolant and the flow intensity of the airflow in real time according to the current heat dissipation requirements. When the test power is low or the heat dissipation requirements are not high, the variable frequency water-cooled box can automatically reduce the speed of the water pump and fan, thereby reducing energy consumption and noise; while when the test power is high or the heat dissipation requirements are high, the variable frequency water-cooled box can quickly increase the speed of the water pump and fan to ensure efficient circulation of the coolant and sufficient airflow, thereby achieving rapid heat dissipation of the integrated circuit board 3.

[0110] Furthermore, the variable frequency water-cooled chamber boasts excellent stability and durability. Its built-in intelligent control system can monitor the operating status of the cooling system and the temperature of the coolant in real time, and automatically adjust and optimize according to actual conditions. This design not only extends the service life of the cooling system but also ensures the stability and reliability of the automatic testing machine during long-term, high-intensity testing.

[0111] In summary, this embodiment utilizes a variable frequency water-cooled box as the core component of the heat dissipation system, demonstrating not only high innovation and practicality but also making a significant contribution to improving the performance and optimizing the efficiency of the automatic testing machine. By intelligently adjusting the speed of the water pump and fan, the variable frequency water-cooled box can achieve efficient heat dissipation for the integrated circuit board 3, while reducing energy consumption and noise.

[0112] Although this application uses terms such as test box and handle 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.

[0113] This utility model provides an automatic testing machine with a quick board replacement function. By setting an interconnected handle and a double elbow clamping mechanism on the top of the test chamber, the test boards located on the top worktable of the test chamber can be clamped or released by operating the handle to drive the double elbow clamping mechanism, thereby realizing quick and convenient replacement of test boards. This not only helps to significantly improve work efficiency, but also brings a better operating experience to the operator.

[0114] 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.
